Definitions
- the present invention relates to a movable weather protection roof according to the preamble of claim 1.
- Temporary roofing is a great advantage for longer construction or renovation work on buildings. This allows you to work largely independently of the weather and protects not only the workers involved but also the building. This is particularly important if, for example, a roof has to be re-covered or a complete roof structure has to be renewed. Since this work usually takes a few days to weeks, the affected building would be unprotected against rain and other precipitation in the meantime. Temporary covering with tarpaulins and other makeshift materials reduces the risk of major damage, but then it is not possible to continue work during a bad weather phase.
- Temporary canopies are known in the form of roof trusses supporting a roof membrane, which are supported on a support and span the site to be protected.
- the supports on both sides of the site are usually formed by scaffolding or lattice girders.
- other options can also be used, such as walls or walls in the vicinity of shell constructions or neighboring buildings. This is especially true when the workplace in the midst of dense development, where there is no space to erect scaffolding, is perhaps the only way to support a temporary weather protection roof.
- the roof trusses can be lattice girders or be constructed in some other way.
- the roof skin can be a rigid roof skin in the form of panels, in which case a single roof truss would be sufficient to support a weather protection roof of limited dimensions. Panels also have the advantage of being more stable and offering better protection against snow and hail, for example.
- Fabric or plastic tarpaulins are more common than roof skins because they are cheaper and lighter. These are then either stretched as a whole tent-like over the roof trusses or, much easier and safer in the wind, stretched in sections between the roof trusses.
- the roof trusses are equipped with rollers, with the usual double-ended roof trusses at least one roller per end, and a guide means is placed on the upper end of the support, which can guide the rollers along a path in a track.
- the guiding means are lattice girders with a triangular cross-section, each consisting of a round belt at each corner and transverse and diagonal struts running between them. Two round belts lie on the support and the top of the third forms a guide rail for rollers of the roof trusses.
- the disclosure document DE 1 684 162 shows movable weather protection roofs in which rollers are mounted in downwardly open U-shaped rails and run on C-profiles serving as running rails, whereby excavation protection is achieved in that the U-shaped roller bearing has an L-shaped on one side into which C-profile has engaging extension.
- the publication font JP-H-5-195633A discloses a weather protection roof which can be moved over rollers running on rails in the form of I-beams, the roller bearing being extended downwards and having additional, smaller rollers that engage behind the roller support surface of the I-beam and form a low-friction excavation protection. What all these anti-excavation safeguards have in common is that they are firmly integrated into the weather protection roof or at least cannot be attached easily and quickly.
- the present invention has therefore set itself the task of creating a movable weather protection roof which has a simple and quick-to-attach anti-excavation protection device which hinders the placing of the weather protection roof on its running rail as little as possible.
- a running rail as a guide means for the role (s) of the roof truss, which compared to those known in the prior art Runways have an additional structure, namely securing beads, which interact mechanically with appropriately shaped securing means of the rollers.
- Bead is to be understood here as a bulge or thickening of the rail profile extending over a certain length along the rail.
- a width of the rail or of the rail cross-section measured essentially perpendicular to the vertical direction of the installed running rail has at least a maximum in the course from top to bottom.
- a bead in the sense of the present invention can also be realized, for example, by choosing a rail whose cross-sectional outline comprises an arc of a circle, an ellipse or an oval with an angular extent of more than 180 degrees.
- the bead and / or the running rail have a constant cross section along their course.
- the beads can have a variable size in the course of the rail or they can not be present in sections.
- Such “gaps” can be bridged by a corresponding design of the securing means of the rollers, especially with regard to their extension in the direction of travel along the rail.
- the running rail or its cross-section it is generally not necessary for the running rail or its cross-section to have a symmetry, for example a mirror symmetry.
- this can be useful for further considerations, for example because it allows the running rail to be installed in both orientations, which on the one hand eliminates a source of error and on the other hand, it also enables even wear.
- the securing means of the rollers are to be understood as structures or shapes of the rollers, which are adapted to the shape of the bead in such a way that the roller has only a small play of perhaps one to a few millimeters in the vertical direction, but cannot be moved beyond that and thus against Lifting or lifting are secured.
- the securing means are designed so that they engage behind the bead of the running rail.
- the present invention proposes that these be designed as retaining clips that are attached or molded to the roller bearing in a stationary manner.
- the clamp can be formed as an integral part, as it were as a continuation, of the roller bearing and can be released or moved by inserting a lockable hinge.
- it is proposed as possibly the simplest solution to provide the retaining clip as a separate part that is clamped between the axle nut and the roller bearing. On the one hand, this is an inexpensive solution and also enables the retaining clips to be retrofitted to existing rollers.
- the present invention proposes releasably connecting the securing means of the rollers to the rollers.
- these can be clamped between the roller bearing and the axle nuts.
- a concave indentation of the roller surface is the securing means, a deliberate lifting can be achieved that the securing bead has interruptions, for example in one or both end regions of the running rail or also at certain, for example regular intervals between them. It is important here that the roller can be moved along the entire length of the running rail without any obstacles, so that the bead is not expanded by further protruding parts attached in places, thus preventing a smooth interaction with the securing means.
- the use according to the invention provides that the running rail is first mounted on the support, which includes placing, aligning and fastening, for example by screwing. Then the roof truss with the roller attached on the underside is lifted, usually by means of a crane, possibly also by hand in the case of small weather protection roofs, and placed with the roller on the installed running rail.
- the roof truss with the roller attached on the underside is lifted, usually by means of a crane, possibly also by hand in the case of small weather protection roofs, and placed with the roller on the installed running rail.
- rollers with a running surface that is complementary to the rail with beads this is only possible at points on the rail where the beads are interrupted, ie the roof truss must in this case still be moved from the placement point to its final position.
- the same procedure can be used, which allows the securing means to be attached to the ground before the roof truss is lifted. Or the roof truss is first lifted on the roller with or without an opened securing device and placed on the running rail and the securing device is only attached or closed there. This has the advantage that the roof truss can also be placed at its approximate end position, even if the securing beads are not interrupted there.
- the present invention thus enables a movable weather protection roof which is secured against unintentional lifting at any time during its use and remains movable as required.
- the additional effort in the form of additional material for the production of the rail and the securing means and their attachment is minimal and, at best, only consists of attaching a retaining clip to the roller bearing.
- the present invention can be implemented in the most general case with only a single roof truss, which has a roller on the underside, in particular if a rigid roof skin is used, for example in the form of a plate (s) attached to the roof truss.
- the equilibrium would either be maintained by the fact that the role lies in the vertical projection of the center of gravity of the roof truss and roof skin and has a corresponding lateral extent.
- the roof truss is mounted stationary with one end and only the other end is movable.
- a rail curved in the shape of an arc of a circle must be used, or the roller can be moved at least to a limited extent along the roof truss, for example by being fastened to a slide guided on a rail of the roof truss.
- roof truss there are more than one roof truss, which on the one hand facilitates a statically stable support of the weather canopy and, on the other hand, the use of elastic roof skins in the form of fabric or plastic tarpaulins which can be stretched over or between the roof trusses.
- elastic roof skins in the form of fabric or plastic tarpaulins which can be stretched over or between the roof trusses.
- keder tarpaulins which have a keder bead on their edges, which is inserted into a complementary keder groove or rail running along the side of the roof trusses.
- the roof trusses used also have more than one role.
- two or more rollers can also be attached to the roof truss one behind the other in the direction of travel.
- a configuration with 2x2 rollers also allows a symmetrically supported, individually stable movable roof truss with the smallest possible number of rollers. If a symmetrical support is dispensed with, a 1 + 2 configuration is also conceivable.
- the present invention preferably proposes the use of a straight running rail. This corresponds to the most common field of application for weather protection roofs, which should usually be able to be moved in a straight line. Alternatively, however, it is also conceivable to use curved rails, for example to move a weather protection roof along an angled or curvilinear building.
- the securing beads of the running rail can be part of the running surface or formed on it. However, it preferably runs along one, particularly preferably along opposite sides.
- the former enables excavation protection with minimal material expenditure, the latter guarantees excavation protection against oblique, ie not vertical, forces acting.
- the running rail of the present invention preferably has at least a large part of a symmetrical cross-section, more precisely a cross-section that is symmetrical with regard to straight line reflection on the vertical. This ensures that the orientation in which the rail is installed is not important, which makes installation easier and faster and also allows alternate installation only in one orientation, which ensures that wear is as uniform as possible.
- the running rail is advantageously connected to a base plate, or the latter is formed as an integral part of the rail.
- This base plate is used for the (detachable) connection to the support and for this purpose has, for example, downwardly protruding pins or holes for receiving bolts.
- steel is often used for the guide rails of weather protection roofs because it is cheap and has high strength.
- the running rail is preferably made of aluminum in order to save weight manufactured and also designed as a hollow rail. In order to guarantee sufficient strength in spite of this, it is proposed to equip the running rail with struts on the inside, in particular one or two diagonal struts.
- the securing beads can either be present continuously along the entire rail. Then, however, it would be difficult or impossible to put on roles with non-releasable securing means and even in the case of roles with releasable securing means this would have to be attached or brought into position afterwards, which would be very cumbersome in practice.
- the beads can also be interrupted at other points, for example at regular intervals. In the most general case, even if they have interruptions, the beads have a variable cross-section, so they could become wider and narrower or higher and lower in the course of the rail within certain limits without losing their basic function.
- the present invention preferably proposes that the cross-section of the bead be selected to be essentially constant, with the exception of any sections that are short compared to the entire length of the rail. This guarantees a uniform rolling and thus also a uniform wear and everywhere the same vertical play of the roles and, moreover, simplifies the production of the running rail according to the invention.
- the present invention proposes this either as a; to design complementary concave indentation of the roller or its running surface to the beads.
- the brackets can be formed as an integral part, to a certain extent as a continuation, of the roller bearing. But then they would not be detachable or movable. The latter could be achieved by inserting a lockable hinge.
- the support which carries the weather protection roof according to the invention and on which the running rail according to the invention is mounted on the upper side can be, for example, a (house) wall, a scaffolding or a lattice girder construction.
- an adapter comprising one, preferably two, essentially horizontally extending crossbars be mounted on the support.
- a carrier plate is also mounted on the top crossbar, which serves as a direct base for the running rail and is releasably connected to it, for example via bolts.
- the roller attached to the underside of the roof truss preferably has a concave running surface, which guarantees stable guidance laterally, i.e. transversely to the direction of travel, on the correspondingly convex and complementary shaped upper side of the running rail.
- the roll is lateral relative to the roof truss, i. E. in the longitudinal direction of the roof truss, attached to it so as to be displaceable by a certain distance. This is particularly preferably implemented by means of a slide which is guided on a rail extending in the longitudinal direction of the roof truss and to which the roller is attached.
- FIG. 1 shows a preferred embodiment of a movable weather protection roof according to the invention.
- Weather protection roof 1 comprises roof trusses 2 consisting of lattice girders, which are supported on both sides on a support 4. At the connection between the support 4 and the roof truss 2 there is a rail 3.
- Detail A shows an enlarged section of an end area of a roof truss 2, as well as the uppermost part of the support 4 with running rail 3 in between.
- the support 4 is closed at the top by an adapter 42 on which the running rail 3 is mounted.
- Roller 21, which is also attached to a slide 23 guided on lateral rail 22 by roof trusses 2, can be moved in a guided manner on running rail 3 along its longitudinal or longitudinal direction, which here extends into the plane of the drawing.
- roller 21 is also movable in the lateral direction, that is to say transversely to the direction of travel, which reduces the requirements for the exactly parallel alignment of the running rails 3 present on both sides of the roof center.
- Running rail 3 has a mirror-symmetrical cross-section with a securing bead 31 each on the left and right, which is engaged from behind by retaining clips 211 as securing means of roller 21, which are attached in the area of the axle bearing.
- the thus interacting securing means and securing bead guarantee a safeguard against unintentional lifting of the role, with a small amount of play remaining in the vertical direction in order to ensure smooth and low-wear running.
- Runway 2 is designed as a hollow rail to reduce its weight.
- struts in the form of diagonal struts 32 are provided inside. This is particularly advisable if, as preferred by the present invention, the running rail 3 is made of aluminum. Integral to rail 3 is formed on the underside of the base plate 33, which over Bolt makes the connection with carrier plate 422 of adapter 42.
- FIG 2 are cross-sections of the running rail in two partial figures Figure 1 shown.
- Part A shows running rail 3 from Figure 1 in cross section and illustrates its mirror-symmetrical structure, the axis of symmetry or plane being indicated by dashed lines and denoted by S. Accordingly, there are two securing beads 31, one on each side of the rail.
- the rail 3 is hollow in its interior, but is stiffened there by diagonal struts 32.
- a base plate 33 is molded on, which serves to further stabilize the rail against bending in the lateral direction and to fasten it to the support, more precisely preferably to the support plate 421 of the adapter 42 of the support.
- Part B shows the cross section of the rail 3 from part A, but supplemented by a roller 21 depicted in cross section with a concavely indented running surface.
- the flanks 212 of the roller 21, which serve as securing means, enclose and grip behind the securing beads 31 on both sides of the running rail 3 like pliers and thus form a further possible implementation of the excavation safeguard of the movable weather protection roof according to the invention.

Description
Vorliegende Erfindung befasst sich mit einem verfahrbaren Wetterschutzdach gemäß des Oberbegriffs des Anspruchs 1.The present invention relates to a movable weather protection roof according to the preamble of claim 1.
Bei längeren Bau- oder Renovierungsarbeiten an Gebäuden ist eine temporäre Überdachung von großem Vorteil. Diese erlaubt es, weitgehend unabhängig von der Witterung zu arbeiten und schützt hierbei nicht nur die beteiligten Arbeiter sondern genauso das Gebäude. Dies ist besonders wichtig wenn zum Beispiel ein Dach neu gedeckt oder ein kompletter Dachstuhl erneuert werden muss. Da diese Arbeiten üblicherweise einige Tage bis Wochen benötigen wäre das betroffene Gebäude in der Zwischenzeit gegen Regen und andere Niederschläge ungeschützt. Provisorisches Abdecken mit Planen und anderen Behelfsmitteln vermindert zwar die Gefahr, dass größere Schäden entstehen, jedoch ist dann während einer Schlechtwetterphase keine Fortführung der Arbeit möglich.Temporary roofing is a great advantage for longer construction or renovation work on buildings. This allows you to work largely independently of the weather and protects not only the workers involved but also the building. This is particularly important if, for example, a roof has to be re-covered or a complete roof structure has to be renewed. Since this work usually takes a few days to weeks, the affected building would be unprotected against rain and other precipitation in the meantime. Temporary covering with tarpaulins and other makeshift materials reduces the risk of major damage, but then it is not possible to continue work during a bad weather phase.
Temporäre Überdachungen sind bekannt in Form von eine Dachhaut tragenden Dachbindern, welche auf ein Auflager abgestützt werden und die zu schützende Stätte überspannen. Die Auflager zu beiden Seiten der Stätte sind meist durch Gerüste oder Gitterträger gebildet. Es können je nach Situation jedoch auch andere Möglichkeiten genutzt werden, etwa in der Nähe stehende Wände bzw. Mauen von Rohbauten oder Nachbargebäuden. Dies ist insbesondere dann, wenn die Arbeitsstätte inmitten dichter Bebauung liegt, wo kein Platz zum Errichten eines Gerüstes ist, vielleicht die einzige Möglichkeit zur Abstützung eines temporären Wetterschutzdaches.Temporary canopies are known in the form of roof trusses supporting a roof membrane, which are supported on a support and span the site to be protected. The supports on both sides of the site are usually formed by scaffolding or lattice girders. However, depending on the situation, other options can also be used, such as walls or walls in the vicinity of shell constructions or neighboring buildings. This is especially true when the workplace in the midst of dense development, where there is no space to erect scaffolding, is perhaps the only way to support a temporary weather protection roof.
Die Dachbinder können hierbei Gitterträger sein, oder anderweitig konstruiert sein. Die Dachhaut kann eine steife Dachhaut in Form von Platten sein, in welchem Falle auch ein einzelner Dachbinder ausreichen würde, um ein Wetterschutzdach begrenzter Abmessungen zu tragen. Weiterhin haben Platten den Vorteil, stabiler zu sein und beispielsweise gegen Schnee und Hagel besseren Schutz zu bieten. Häufiger weil kostengünstiger und leichter sind jedoch Stoff- oder Kunststoffplanen als Dachhäute. Diese werden dann entweder als Ganzes zeltartig über die Dachbinder gespannt oder, wesentlich einfacher und bei Wind auch sicherer, Abschnittsweise zwischen die Dachbinder gespannt.The roof trusses can be lattice girders or be constructed in some other way. The roof skin can be a rigid roof skin in the form of panels, in which case a single roof truss would be sufficient to support a weather protection roof of limited dimensions. Panels also have the advantage of being more stable and offering better protection against snow and hail, for example. Fabric or plastic tarpaulins are more common than roof skins because they are cheaper and lighter. These are then either stretched as a whole tent-like over the roof trusses or, much easier and safer in the wind, stretched in sections between the roof trusses.
Beim Errichten großer Wetterschutzdächer stellt sich das Problem, jeden Dachbinder an seine vorgesehene Position zu bringen. Dies ist dann möglich, wenn der oder die verwendeten Kräne über entsprechende Reichweite verfügen, entweder indem sie entsprechend lange Ausleger haben oder als Ganzes verfahrbar sind. Ist dies nicht der Fall, d.h. kann der Kran nicht jede Position des zu errichtenden Wetterschutzdaches erreichen, bleibt nur, die einzelnen Dachbinder verfahrbar zu gestalten. Dies hat zusätzlich noch den Vorteil, dass ein Wetterschutzdach auch kleiner als das zu bearbeitende Gebiet ausgelegt werden kann und nur immer über die konkrete Arbeitsstelle gefahren wird. Dies spart Material und Zeit.When erecting large weather protection roofs, the problem arises of bringing each roof truss to its intended position. This is possible if the crane or cranes used have an appropriate range, either by having correspondingly long booms or by being movable as a whole. If this is not the case, ie the crane cannot reach every position of the weather protection roof to be erected, all that remains is to make the individual roof trusses movable. This has the additional advantage that a weather protection roof can also be designed to be smaller than the area to be worked and is only driven over the specific work site. This saves material and time.
Um das Dach verfahrbar zu machen, werden die Dachbinder mit Rollen ausgestattet, bei den üblichen zweiendigen Dachbindern mindestens eine Rolle je Ende, und auf das obere Ende des Auflagers wird ein Führungsmittel aufgelegt, welches die Rollen entlang eines Fahrweges in einer Spur führen kann. Als Führungsmittel sind im Stand der Technik Gitterträgers mit dreieckigem Querschnitt aus je einem Rundgurt an jeder Ecke und dazwischen verlaufenden Quer- und Diagonalstreben. Zwei Rundgurte liegen auf dem Auflager und der dritte bildet mit seiner Oberseite eine Führungsschiene für Rollen der Dachbinder.To make the roof movable, the roof trusses are equipped with rollers, with the usual double-ended roof trusses at least one roller per end, and a guide means is placed on the upper end of the support, which can guide the rollers along a path in a track. In the prior art, the guiding means are lattice girders with a triangular cross-section, each consisting of a round belt at each corner and transverse and diagonal struts running between them. Two round belts lie on the support and the top of the third forms a guide rail for rollers of the roof trusses.
Diese Lösung hat jedoch den Nachteil, das ein solchermaßen fahrbar gelagertes Dachsegment leicht durch Einwirkung von entsprechend starkem und/oder unter ungünstigem Winkel einfallendem Wind oder wenn die Führungsschienen nicht parallel ausgerichtet sind aus der Führung springen oder sogar ganz abgehoben und beschädigt werden.However, this solution has the disadvantage that such a movably mounted roof segment can easily jump out of the guide or even be completely lifted off and damaged by the action of correspondingly strong and / or incident winds at an unfavorable angle or if the guide rails are not aligned parallel.

What all these anti-excavation safeguards have in common is that they are firmly integrated into the weather protection roof or at least cannot be attached easily and quickly.
Vorliegende Erfindung hat sich daher die Aufgabe gestellt, ein verfahrbares Wetterschutzdach zu schaffen, welches über eine simple und schnell anzubringende Aushubsicherung verfügt, welche das Aufsetzen des Wetterschutzdachs auf seine Fahrschiene möglichst wenig behindert.The present invention has therefore set itself the task of creating a movable weather protection roof which has a simple and quick-to-attach anti-excavation protection device which hinders the placing of the weather protection roof on its running rail as little as possible.
Gelöst wird diese Aufgabe durch ein Wetterschutzdach mit den Merkmalen des unabhängigen Anspruchs 1, welches erfindungsgemäß wie in Anspruch 11 beschrieben verwendet wird.This object is achieved by a weather protection roof with the features of independent claim 1, which is used according to the invention as described in claim 11.
Wesentlich für vorliegende Erfindung ist das vorsehen einer Fahrschiene als Führungsmittel für die Rolle(n) des Dachbinders, welche gegenüber den im Stand der Technik bekannten Fahrschienen über eine zusätzliche Struktur, nämlich Sicherungswülste verfügt, welche mit entsprechend geformten Sicherungsmitteln der Rollen mechanisch zusammenwirken. Wulst ist hier als eine sich über eine gewisse Länge entlang der Schiene hinziehende Ausbuchtung oder Verdickung des Schienenprofils zu verstehen. Maßgeblich ist, dass eine im Wesentlichen senkrecht zur Vertikalrichtung der verlegten Fahrschiene gemessene Breite der Schiene bzw. des Schienen Querschnitts im Verlauf von oben nach unten zumindest ein Maximum aufweist. Somit kann ein Wulst im Sinne vorliegender Erfindung beispielsweise auch realisiert werden, indem eine Schiene gewählt wird, deren Querschnittsumriss einen Kreisbogen, eine Ellipse oder ein Oval mit einer Winkelerstreckung von mehr als 180 Grad umfasst.It is essential for the present invention to provide a running rail as a guide means for the role (s) of the roof truss, which compared to those known in the prior art Runways have an additional structure, namely securing beads, which interact mechanically with appropriately shaped securing means of the rollers. Bead is to be understood here as a bulge or thickening of the rail profile extending over a certain length along the rail. What is decisive is that a width of the rail or of the rail cross-section measured essentially perpendicular to the vertical direction of the installed running rail has at least a maximum in the course from top to bottom. Thus, a bead in the sense of the present invention can also be realized, for example, by choosing a rail whose cross-sectional outline comprises an arc of a circle, an ellipse or an oval with an angular extent of more than 180 degrees.
Dabei ist in der allgemeinsten Form vorliegender Erfindung nicht erforderlich, dass der Wulst und/oder die Fahrschiene entlang ihres Verlaufes einen gleichbleibenden Querschnitt haben. Die Wülste können im Schienenverlauf eine variable Größe aufweisen oder dabei abschnittsweise nicht vorhanden sein. Solche 'Lücken' können durch eine entsprechende Ausgestaltung der Sicherungsmittel der Rollen, besonders hinsichtlich ihrer Ausdehnung in Verfahrrichtung entlang der Schiene überbrückt werden.In the most general form of the present invention, it is not necessary that the bead and / or the running rail have a constant cross section along their course. The beads can have a variable size in the course of the rail or they can not be present in sections. Such “gaps” can be bridged by a corresponding design of the securing means of the rollers, especially with regard to their extension in the direction of travel along the rail.
Des Weiteren ist es allgemein zur Erreichung des Erfindungszweckes nicht erforderlich, dass die Fahrschiene bzw. ihr Querschnitt eine Symmetrie, etwa eine Spiegelsymmetrie aufweist. Dies kann jedoch aus weitergehenden Überlegungen sinnvoll sein, etwa weil es eine Montage der Fahrschiene in beiden Orientierungen erlaubt, was zum einen eine Fehlerquelle beseitigt und zum anderen auch eine gleichmäßige Abnutzung ermöglicht.Furthermore, in order to achieve the purpose of the invention, it is generally not necessary for the running rail or its cross-section to have a symmetry, for example a mirror symmetry. However, this can be useful for further considerations, for example because it allows the running rail to be installed in both orientations, which on the one hand eliminates a source of error and on the other hand, it also enables even wear.
Die Sicherungsmittel der Rollen sind als Strukturen oder Formgebung der Rollen zu verstehen, welche der Form des Wulstes insofern angepasst sind, dass die Rolle in Vertikalrichtung nur ein geringes Spiel von vielleicht einem bis einigen Millimetern haben, jedoch darüber hinaus nicht bewegt werden können und somit gegen Ab- oder Ausheben gesichert sind. Hierzu sind die Sicherungsmittel so gestaltet, dass sie den Wulst der Fahrschiene hintergreifen.The securing means of the rollers are to be understood as structures or shapes of the rollers, which are adapted to the shape of the bead in such a way that the roller has only a small play of perhaps one to a few millimeters in the vertical direction, but cannot be moved beyond that and thus against Lifting or lifting are secured. For this purpose, the securing means are designed so that they engage behind the bead of the running rail.
Für die Sicherungsmittel der Rollen schlägt vorliegende Erfindung vor, diese als Halteklammern auszuführen, die stationär am Rollenlager angebracht oder angeformt werden. Die Klammer kann als integraler Teil, gewissermaßen als Fortsetzung, des Rollenlagers ausgeformt sein und durch Einfügen eines verriegelbaren Scharniers lösbar oder beweglich werden. Als möglicherweise einfachste Lösung wird alternativ vorgeschlagen, die Halteklammer als separates Teil vorzusehen, das zwischen Achsmutter und Rollenlager festgeklemmt wird. Dies ist zum einen eine günstige Lösung und ermöglicht weiterhin, die Halteklammern an bereits vorhandenen Rollen nachzurüsten.For the securing means of the rollers, the present invention proposes that these be designed as retaining clips that are attached or molded to the roller bearing in a stationary manner. The clamp can be formed as an integral part, as it were as a continuation, of the roller bearing and can be released or moved by inserting a lockable hinge. As an alternative, it is proposed as possibly the simplest solution to provide the retaining clip as a separate part that is clamped between the axle nut and the roller bearing. On the one hand, this is an inexpensive solution and also enables the retaining clips to be retrofitted to existing rollers.
In jedem Fall ist so vorteilhaft erreicht, dass eine Bewegung der Rollen in vertikale Richtung nur begrenzt möglich, ein ungewolltes ausheben also wirksam verhindert ist. Hierbei ist darauf zu achten, dass zur Vermeidung von Reibungsverlusten und vorzeitigem Verschleiß ein ausreichendes Spiel verbleibt, welches vorzugsweise im Bereich von einem Millimeter bis einem Zentimeter liegt.In any case, it is achieved so advantageously that a movement of the rollers in the vertical direction is only possible to a limited extent, so that unintentional digging is effectively prevented. It is important to ensure that sufficient play remains, which is preferably in the range of one millimeter to one centimeter, in order to avoid frictional losses and premature wear.
Um gewolltes Ab- oder Ausheben der Rollen und damit der Dachelemente zu ermöglichen, schlägt vorliegende Erfindung vor, die Sicherungsmittel der Rollen lösbar mit den Rollen zu verbinden. Bei Einsatz von stationären Klammern, können diese etwa zwischen Rollenlager und Achsmuttern festgeklemmt werden. Ist eine konkave Einbuchtung der Rollenoberfläche das Sicherungsmittel, kann ein ein gewolltes Ausheben dadurch erreicht werden, dass der Sicherungswulst Unterbrechungen aufweist, etwa in einem oder beiden Endbereichen der Fahrschiene oder auch in gewissen, beispielsweise regelmäßigen Abständen dazwischen. Wichtig ist hierbei, dass die Rolle entlang der gesamten Länge der Fahrschiene hindernislos verfahrbar ist, der Wulst also nicht durch stellenweise angebrachte weiter hervorstehende Teile erweitert und so ein reibungsloses Zusammenwirken mit den Sicherungsmitteln verhindert wird. Die erfindungsgemäße Verwendung sieht vor, dass zunächst die Fahrschiene auf dem Auflager montiert wird, was Aufsetzen, Ausrichten und Befestigen, etwa durch Festschrauben, umfasst. Danach wird der Dachbinder mit unterseitig angebrachter Rolle, üblicherweise mittels eines Krans, bei kleinen Wetterschutzdächern möglicherweise auch von Hand, angehoben und mit der Rolle auf die montierte Fahrschiene aufgesetzt. Bei Rollen mit komplementär zur Schiene mit Wülsten geformter Lauffläche ist dies nur an Stellen der Schiene möglich, wo die Wülste unterbrochen sind, d.h. der Dachbinder muss in diesem Falle von der Aufsetzstelle noch an seine endgültige Position gefahren werden. Bei einer Rolle mit lösbar angebrachten oder beweglichen Sicherungsmitteln, beispielsweise angeschraubten Klammern, kann entweder genauso vorgegangen werden, was es erlaubt die Sicherungsmittel schon am Boden vor dem Anheben des Dachbinders zu befestigen. Oder der Dachbinder wird zunächst ohne oder mit geöffnetem Sicherungsmittel an der Rolle angehoben und auf die Fahrschiene gesetzt und dass Sicherungsmittel erst dort angebracht bzw. geschlossen. Dies hat den Vorzug dass der Dachbinder auch gleich an seiner ungefähren Endposition aufgesetzt werden kann, auch wenn die Sicherungswülste dort nicht unterbrochen i sind.In order to enable the rollers and thus the roof elements to be lifted or lifted out, the present invention proposes releasably connecting the securing means of the rollers to the rollers. When using stationary clamps, these can be clamped between the roller bearing and the axle nuts. If a concave indentation of the roller surface is the securing means, a deliberate lifting can be achieved that the securing bead has interruptions, for example in one or both end regions of the running rail or also at certain, for example regular intervals between them. It is important here that the roller can be moved along the entire length of the running rail without any obstacles, so that the bead is not expanded by further protruding parts attached in places, thus preventing a smooth interaction with the securing means. The use according to the invention provides that the running rail is first mounted on the support, which includes placing, aligning and fastening, for example by screwing. Then the roof truss with the roller attached on the underside is lifted, usually by means of a crane, possibly also by hand in the case of small weather protection roofs, and placed with the roller on the installed running rail. In the case of rollers with a running surface that is complementary to the rail with beads, this is only possible at points on the rail where the beads are interrupted, ie the roof truss must in this case still be moved from the placement point to its final position. In the case of a roll with detachably attached or movable securing means, for example screwed-on clips, the same procedure can be used, which allows the securing means to be attached to the ground before the roof truss is lifted. Or the roof truss is first lifted on the roller with or without an opened securing device and placed on the running rail and the securing device is only attached or closed there. This has the advantage that the roof truss can also be placed at its approximate end position, even if the securing beads are not interrupted there.
Vorliegende Erfindung ermöglicht also ein verfahrbares Wetterschutzdach, welches während seiner Benutzung gegen ungewolltes Ausheben jederzeit gesichert ist und dabei beliebig verfahrbar bleibt. Der Zusatzaufwand in Form zusätzlichen Materials für die Herstellung der Schiene sowie die Sicherungsmittel und deren Anbringung ist minimal und besteht günstigenfalls nur aus der Anbringung einer Halteklammer am Rollenlager.The present invention thus enables a movable weather protection roof which is secured against unintentional lifting at any time during its use and remains movable as required. The additional effort in the form of additional material for the production of the rail and the securing means and their attachment is minimal and, at best, only consists of attaching a retaining clip to the roller bearing.
Vorteilhafte Weiterbildungen vorliegender Erfindung, welche Einzeln oder in Kombination realisierbar sind, sofern sie sich nicht offensichtlich gegenseitig ausschließen, sollen im Folgenden beschrieben werden.Advantageous developments of the present invention, which can be implemented individually or in combination, provided they are not obviously mutually exclusive, are to be described below.
Vorliegende Erfindung ist im allgemeinsten Fall mit nur einem einzelnen Dachbinder umsetzbar, der über eine unterseitige Rolle verfügt, insbesondere wenn eine steife Dachhaut eingesetzt wird, etwa in Form von (einer) am Dachbinder befestigten Platte(n). Das Gleichgewicht würde entweder dadurch gewahrt, dass die Rolle in der vertikalen Projektion des Massenschwerpunkts von Dachbinder und Dachhaut liegt und eine entsprechende laterale Ausdehnung aufweist. Oder der Dachbinder ist mit einem Ende stationär gelagert und nur das andere Ende ist beweglich. In diesem Fall muss entweder eine kreisbogenförmig gekrümmte Schiene eingesetzt werden, oder die Rolle ist entlang des Dachbinders zumindest begrenzt beweglich, etwa indem sie an einem auf einer Schiene des Dachbinders geführten Schlitten befestigt ist.The present invention can be implemented in the most general case with only a single roof truss, which has a roller on the underside, in particular if a rigid roof skin is used, for example in the form of a plate (s) attached to the roof truss. The equilibrium would either be maintained by the fact that the role lies in the vertical projection of the center of gravity of the roof truss and roof skin and has a corresponding lateral extent. Or the roof truss is mounted stationary with one end and only the other end is movable. In this case, either a rail curved in the shape of an arc of a circle must be used, or the roller can be moved at least to a limited extent along the roof truss, for example by being fastened to a slide guided on a rail of the roof truss.
Üblicherweise sind jedoch mehr als ein Dachbinder vorhanden, was es zum einen erleichtert eine statisch stabile Abstützung des Wetterdaches zu erreichen und zum anderen die Verwendung elastischer Dachhäute in Form von Stoff- oder Kunststoffplanen ermöglicht, welche über oder Zwischen den Dachbindern gespannt werden können. Diese sind billiger in der Anschaffung und einfacher in der Montage im Vergleich zu steifen Platten. Dies gilt insbesondere für sogenannte Kederplanen, welche an ihren Rändern über einen Kederwulst verfügen, der in eine seitlich an den Dachbindern entlang verlaufende komplementäre Kedernut oder -schiene eingeschoben werden. Diese erlauben eine besonders einfache Montage auch durch eine kleine Zahl von Arbeitern.Usually, however, there are more than one roof truss, which on the one hand facilitates a statically stable support of the weather canopy and, on the other hand, the use of elastic roof skins in the form of fabric or plastic tarpaulins which can be stretched over or between the roof trusses. These are cheaper to buy and easier to assemble compared to rigid panels. This applies in particular to so-called keder tarpaulins, which have a keder bead on their edges, which is inserted into a complementary keder groove or rail running along the side of the roof trusses. These allow a particularly simple assembly even by a small number of workers.
Weiterhin verfügen die eingesetzten Dachbinder auch über mehr als eine Rolle. Insbesondere wird vorgeschlagen zwei Rollen vorzusehen, von die beidseitig des Schwerpunktes des Dachbinders angebracht werden, beispielsweise im Bereich der Enden der üblicherweise zweiendigen Dachbinder. Um eine Stabilität eines einzelnen Dachbinders gegen umkippen in Richtung entlang der Fahrschiene zu garantieren, können auch zwei oder mehr Rollen in Fahrrichtung hintereinander am Dachbinder angebracht sein. Insbesondere eine Konfiguration mit 2x2 Rollen erlaubt einen auch einen symmetrisch abgestützten, einzeln stabil verfahrbaren Dachbinder mit einer möglichst kleinen Zahl an Rollen. Verzichtet man auf eine symmetrische Abstützung ist auch eine 1+2 Konfiguration denkbar.Furthermore, the roof trusses used also have more than one role. In particular, it is proposed to provide two rollers, which are attached on both sides of the center of gravity of the roof truss, for example in the area of the ends of the usually two-ended roof trusses. In order to guarantee the stability of a single roof truss against tipping over in the direction along the running rail, two or more rollers can also be attached to the roof truss one behind the other in the direction of travel. In particular, a configuration with 2x2 rollers also allows a symmetrically supported, individually stable movable roof truss with the smallest possible number of rollers. If a symmetrical support is dispensed with, a 1 + 2 configuration is also conceivable.
Vorliegende Erfindung schlägt bevorzugt vor, eine gerade Fahrschiene zu verwenden. Dies entspricht dem häufigsten Einsatzgebiet von Wetterschutzdächern, die üblicherweise geradlinig verfahrbar sein sollen. Alternativ ist jedoch auch denkbar, gekrümmt verlaufende Schienen zu verwenden um beispielsweise ein Wetterschutzdach entlang eines winkligen oder krummlinig verlaufenden Gebäudes verfahren zur können.The present invention preferably proposes the use of a straight running rail. This corresponds to the most common field of application for weather protection roofs, which should usually be able to be moved in a straight line. Alternatively, however, it is also conceivable to use curved rails, for example to move a weather protection roof along an angled or curvilinear building.
Die Sicherungswülste der Fahrschiene können Teil der Lauffläche bzw. auf dieser angeformt sein. Bevorzugt verläuft er jedoch entlang einer, besonders bevorzugt entlang gegenüberliegender Seiten. Ersteres ermöglicht eine Aushubsicherung mit minimalem Materialaufwand, letzteres garantiert eine Aushubsicherung auch gegenüber schräg, d.h. nicht vertikal, angreifenden Kräften.
Ferner bevorzugt weißt die Fahrschiene vorliegender Erfindung zumindest größtenteils einen symmetrischen Querschnitt, genauer einen Hinsichtlich Geradenspiegelung an der Vertikalen symmetrischen Querschnitt auf. Hierdurch ist erreicht, dass es auf die Orientierung, in der die Schiene montiert wird, nicht ankommt, was die Montage erleichtert und beschleunigt und auch ein Abwechselndes Montieren erst in der einen dann in der anderen Orientierung zulässt, wodurch eine möglichst gleichmäßige Abnutzung sichergestellt wird.
Die Fahrschiene ist vorteilhafterweise mit einer Grundplatte verbunden, bzw. letztere ist als integraler Teil der Schiene angeformt. Diese Grundplatte dient der (lösbaren) Verbindung mit dem Auflager und verfügt hierfür beispielsweise über nach unten abstehende Zapfen oder Löcher zur Aufnahme von Bolzen. Im Stand der Technik wird häufig Stahl für die Führungsschienen von Wetterschutzdächern eingesetzt, da er günstig ist und hohe Festigkeit aufweist. Von vorliegender Erfindung bevorzugt ist die Fahrschiene zur Gewichtsersparnis jedoch aus Aluminium gefertigt und zusätzlich als Hohlschiene ausgeführt. Um dabei trotzdem eine ausreichende Festigkeit zu garantieren, wird vorgeschlagen, die Fahrschiene im Inneren mit Verstrebungen auszustatten, insbesondere einer oder zwei Diagonalverstrebungen.The securing beads of the running rail can be part of the running surface or formed on it. However, it preferably runs along one, particularly preferably along opposite sides. The former enables excavation protection with minimal material expenditure, the latter guarantees excavation protection against oblique, ie not vertical, forces acting.
Furthermore, the running rail of the present invention preferably has at least a large part of a symmetrical cross-section, more precisely a cross-section that is symmetrical with regard to straight line reflection on the vertical. This ensures that the orientation in which the rail is installed is not important, which makes installation easier and faster and also allows alternate installation only in one orientation, which ensures that wear is as uniform as possible.
The running rail is advantageously connected to a base plate, or the latter is formed as an integral part of the rail. This base plate is used for the (detachable) connection to the support and for this purpose has, for example, downwardly protruding pins or holes for receiving bolts. In the prior art, steel is often used for the guide rails of weather protection roofs because it is cheap and has high strength. According to the present invention, however, the running rail is preferably made of aluminum in order to save weight manufactured and also designed as a hollow rail. In order to guarantee sufficient strength in spite of this, it is proposed to equip the running rail with struts on the inside, in particular one or two diagonal struts.
Die Sicherungswülste können entweder durchgängig entlang der gesamten Fahrschiene vorhanden sein. Dann wäre es jedoch schwierig oder nicht möglich, Rollen mit nicht lösbaren Sicherungsmitteln aufzusetzen und auch bei rollen mit lösbarem Sicherungsmittel müsste dieses nachträglich nach dem Aufsetzen angebracht bzw. in Position gebracht werden, was in der Praxis sehr umständlich wäre. Um dies möglich zu machen wir vorgeschlagen, zumindest an einem Ende der Schiene die Wülste zu unterbrechen und so an dieser Stelle ein Aufsetzen auch mit aktivem Sicherungsmittel zu erlauben. Zusätzlich können die Wülste auch an weiteren Stellen unterbrochen werden, beispielsweise in regelmäßigen Abständen. Im Allgemeinsten Fall, etwa auch wenn sie Unterbrechungen aufweisen, haben die Wülste einen variablen Querschnitt, könnte also im Verlauf der Schiene in gewissen Grenzen breiter und schmaler oder höher und niedriger werden, ohne das seine grundsätzliche Funktion verloren ginge. Vorliegende Erfindung schlägt jedoch bevorzugt vor, den Querschnitt des Wulstes mit der Ausnahme von etwaigen, im Vergleich zur gesamten Schienenlänge kurzen Abschnitten im Wesentlichen konstant zu wählen. Dies garantiert ein gleichmäßiges Abrollen und damit auch eine gleichmäßige Abnutzung und überall gleiches vertikales Spiel der Rollen und vereinfacht darüber hinaus die Herstellung der erfindungsgemäßen Fahrschiene.The securing beads can either be present continuously along the entire rail. Then, however, it would be difficult or impossible to put on roles with non-releasable securing means and even in the case of roles with releasable securing means this would have to be attached or brought into position afterwards, which would be very cumbersome in practice. In order to make this possible, we proposed to interrupt the beads at least at one end of the rail and thus to allow placement even with active securing means at this point. In addition, the beads can also be interrupted at other points, for example at regular intervals. In the most general case, even if they have interruptions, the beads have a variable cross-section, so they could become wider and narrower or higher and lower in the course of the rail within certain limits without losing their basic function. However, the present invention preferably proposes that the cross-section of the bead be selected to be essentially constant, with the exception of any sections that are short compared to the entire length of the rail. This guarantees a uniform rolling and thus also a uniform wear and everywhere the same vertical play of the roles and, moreover, simplifies the production of the running rail according to the invention.
Für die Sicherungsmittel der Rollen schlägt vorliegende Erfindung vor, diese entweder als eine ; zu den Wülsten komplementäre konkave Einbauchung der Rolle bzw. ihrer Lauffläche auszugestalten. Dies wäre besonders stabil, könnte also großen Vertikalkräften standhalten, ist aber auch aufwendiger als der zweite, bevorzugte, Vorschlag. Dieser besteht darin, die Sicherungsmittel als Halteklammern auszuführen, die entweder mitrotierend direkt mit den Rollen verbunden werden oder, besonders bevorzugt, stationär am Rollenlager angebracht oder angeformt werden. Die Klammern können als integraler Teil, gewissermaßen als Fortsetzung, des Rollenlagers ausgeformt sein. Dann wären sie jedoch nicht lösbar oder beweglich. Letzteres könnte einfügen eines verriegelbaren Scharniers erreicht werden. Als möglicherweise einfachste und in jedem Fall bevorzugte Lösung wird aber vorgeschlagen, die Halteklammern als separates Teile vorzusehen, die zwischen Achsmutter und Rollenlager festgeklemmt sind. Dies ist zum einen eine günstige Lösung und ermöglicht weiterhin, die Halteklammern an bereits vorhandenen Rollen nachzurüsten.For the securing means of the roles, the present invention proposes this either as a; to design complementary concave indentation of the roller or its running surface to the beads. This would be particularly stable, i.e. it could withstand large vertical forces, but is also more complex than the second, preferred, proposal. This consists in designing the securing means as retaining clips, which are either connected directly to the rollers in a rotating manner or, particularly preferably, are attached or formed in a stationary manner on the roller bearing. The brackets can be formed as an integral part, to a certain extent as a continuation, of the roller bearing. But then they would not be detachable or movable. The latter could be achieved by inserting a lockable hinge. As possibly the simplest and in any case preferred solution, it is proposed to provide the retaining clips as separate parts that are clamped between the axle nut and the roller bearing. On the one hand, this is an inexpensive solution and also enables the retaining clips to be retrofitted to existing rollers.
Das Auflager, welches das erfindungsgemäße Wetterschutzdach trägt und auf welches oberseitig die erfindungsgemäße Fahrschiene montiert wird, kann beispielsweise eine (Haus)Wand, ein Gerüst oder eine Gitterträgerkonstruktion sein. Um eine standardisierte Schnittstelle zur erfindungsgemäßen Fahrschiene bereitzustellen wird vorgeschlagen, dass auf das Auflager Adapter umfassend einen, bevorzugt zwei, im Wesentlichen horizontal verlaufenden Querriegel montiert wird. Auf dem obersten Querriegel wird weiterhin eine Trägerplatte montiert, welche als unmittelbare Unterlage für die Fahrschiene dient und mit dieser etwa über Bolzen lösbar verbunden ist.The support which carries the weather protection roof according to the invention and on which the running rail according to the invention is mounted on the upper side can be, for example, a (house) wall, a scaffolding or a lattice girder construction. In order to provide a standardized interface to the running rail according to the invention, it is proposed that an adapter comprising one, preferably two, essentially horizontally extending crossbars be mounted on the support. A carrier plate is also mounted on the top crossbar, which serves as a direct base for the running rail and is releasably connected to it, for example via bolts.
Die unterseitig des Dachbinders angebrachte Rolle hat bevorzugt eine konkave Lauffläche, was eine lateral, also quer zur Verfahrrichtung, stabile Führung auf der entsprechend konvex und komplementär geformten Oberseite der Fahrschiene garantiert. Besonders bevorzugt ist die Rolle lateral relativ zum Dachbinder, d.h. in Längsrichtung des Dachbinders, um eine gewisse Strecke verschiebbar an diesem angebracht. Dies ist besonders bevorzugt mittels eines auf einer sich in Längsrichtung des Dachbinders erstreckenden Schiene geführten Schlittens realisiert, an dem die Rolle befestigt ist.The roller attached to the underside of the roof truss preferably has a concave running surface, which guarantees stable guidance laterally, i.e. transversely to the direction of travel, on the correspondingly convex and complementary shaped upper side of the running rail. Most preferably the roll is lateral relative to the roof truss, i. E. in the longitudinal direction of the roof truss, attached to it so as to be displaceable by a certain distance. This is particularly preferably implemented by means of a slide which is guided on a rail extending in the longitudinal direction of the roof truss and to which the roller is attached.

Detail A zeigt einen vergrößerten Ausschnitt eines Endbereiches eines Dachbinders 2, sowie den obersten Teil des Auflagers 4 mit Fahrschiene 3 dazwischen. Wie zu sehen wird Auflager 4 zuoberst durch Adapter 42 abgeschlossen, auf welchem die Fahrschiene 3 montiert ist. Auf Fahrschiene 3 entlang deren Längs- oder Longitudinalrichtung, welche hier in die Zeichnungsebene hinreicht, geführt verfahrbar ist Rolle 21, welche weiterhin an einem auf Lateralschiene 22 von Dachbinder 2 geführten Schlitten 23 befestigt ist. Somit ist Rolle 21 auch in lateraler Richtung, also quer zur Verfahrrichtung beweglich, was die Anforderungen an die exakt parallele Ausrichtung der beidseitig des Dachmittelpunktes vorhandenen Fahrschienen 3 verringert.
Detail B stellt einen weiter vergrößerten Ausschnitt aus Detail A dar, in welchem die Fahrschiene 3, die auf ihr laufende Rolle 21 und die Verbindung mit dem Adapter 42 zu erkennen ist. Fahrschiene 3 hat einen spiegelsymmetrischen Querschnitt mit links und rechts je einem Sicherungswulst 31, welcher von im Bereich des Achslagers angebrachten Halteklammern 211 als Sicherungsmittel von Rolle 21 hintergriffen wird. Die so zusammenwirkenden Sicherungsmittel und Sicherungswulst garantieren eine Sicherung gegen ungewolltes Ausheben der Rolle, wobei in vertikaler Richtung ein geringes Spiel verbleibt um einen reibungsfreien und verschleißarmen Lauf zu gewährleisten. Fahrschiene 2 ist um ihr Gewicht zu reduzieren als Hohlschiene ausgeführt. Um dennoch eine ausreichende Festig- und Steifigkeit zu garantieren sind im Inneren Verstrebungen in Form von Diagonalstreben 32 vorgesehen. Dies ist besonders zu empfehlen, wenn, wie von vorliegender Erfindung bevorzugt, die Fahrschiene 3 aus Aluminium gefertigt wird. Integral zu Schiene 3 ist an deren Unterseite Grundplatte 33 angeformt, welche über Bolzen die Verbindung mit Trägerplatte 422 von Adapter 42 herstellt.Detail A shows an enlarged section of an end area of a
