Definitions
- the invention relates to a prefabricated formwork element for the production of blasted concrete corners, with a room-side flat, with reinforcement, as lost formwork serving building board and steel lattice girders as main reinforcement above the building board, which are attached to it, with an angular or round foot and an undercut headboard provided holders is worn.
- the invention now aims to create a formwork element that can be concreted after being moved to a blasted concrete ceiling, etc. without or with only minor assumptions. If necessary, the desired dimensions should only be determined at the construction site, where changes could also be made at short notice.
- Another advantage should be that the elements to be transported to the construction site are relatively light in terms of their weight and with simple mechanical aids, e.g. Light cranes can be moved. In the production of self-made ceilings, one often only needs small ceiling elements, the manufacture of which can be carried out manually without a crane.
- the holders are mushroom-shaped anchors that are non-positively connected to the building board, the reinforcement beams with their longitudinal or tension rods engaging under the heads of the mushroom-shaped anchors or engaging in incisions formed on the anchors, so that a there is a self-supporting formwork element that can be concreted without any supports after moving.
- Self-supporting reinforcement beams are thus arranged on the building board between the rows of anchors, which engage under the heads of the anchors or engage in incisions formed on the anchors. After the reinforcement beams have been latched in between two parallel rows of anchors and these parts, which are now firmly connected to each other, have been placed on corresponding support bearings of the building to be erected, the concrete is introduced onto the building board as so-called lost formwork.
- the reinforcement beams can be designed statically in such a way that either no or only minor supports are to be arranged in order to adequately support the reinforced concrete slab during the setting time of the concrete.
- the formwork parts of the ceiling are assembled in the factory and then stacked and stored on top of each other.
- bars of additional reinforcement can also be inserted into the incisions of the anchors.
- This reinforcement can be installed both in the factory and only on the construction site. So you have an easy to move and easy to transport element that consists of lost formwork, the required ceiling reinforcement and the aforementioned mushroom-shaped anchors, and into which - after moving to the construction site - only the required concrete has to be poured to get the finished reinforced concrete floor.
- the installations can be inserted and the concreting work carried out, as with conventional in-situ concrete ceilings.
- a prefabricated "lost formwork element" is used for the production of, in particular, inclined, reinforced concrete ceilings provided with self-supporting reinforcement beams, preferably lattice girders, with two base plates forming the finished wall or ceiling surface proposed, the special feature of which is that mushroom-shaped anchors are placed on the base plates in parallel rows at intervals, preferably in cross section, and are non-positively connected to the base plates, and that the longitudinal or tension rods of the reinforcement beams, which also serve as spacers, are the heads of the anchors of both Reach under base plates or engage in incisions formed in the anchors.
- FIG. 1 shows a base plate, on which anchors designed in the form of mushrooms are attached in parallel rows.
- Fig. 2 illustrates perspective an apparatus with which the anchor on a Base plate can be placed mechanically.
- Fig. 3 shows stacked base plates with attached anchors for space-saving storage or for transport to the construction site.
- Fig. 4 is a perspective view of a ready-to-move element. 5-12 show different embodiments of anchors in a view or in plan view. 13 illustrates another embodiment of the invention.
- the mushroom-shaped anchors 1 essentially consist of a plate-shaped base 2, the underside of which can be smooth, grooved or structured or also perforated, and possibly have pins 3 around the anchor 1 placed on a formwork panel 4 with the panel during the gluing process in secure in the horizontal direction against displacement. Instead of these two pins (nails), the anchor can also have a hole through which a nail is struck.
- the anchors 1 are displaced in parallel rows in accordance with the grid indicated on the base plate 4 in Fig. 1, e.g. after applying an adhesive on the underside of the anchor, tap it onto the base plate 4 with a hammer, the pins 3 of the anchor penetrating into the material of the plate and thus allowing precise fixing.
- the mushroom-shaped design of the anchors they have a tapered intermediate part or incision 5, which widens again at the upper end and forms a mushroom-shaped head 6.
- these can optionally also be welded or screwed to the base plate 4.
- Free-spanned reinforcement e.g. in the form of a lattice girder 7, as best shown in FIG. 4.
- This reinforcement is advantageously introduced by latching the lower longitudinal rods 8 of the lattice girder, which transmit the tensile forces.
- any suitably designed lattice girder can be used.
- the distances between the anchors 1 in the longitudinal and transverse directions must be dimensioned in accordance with the load when the concrete is placed on the lost formwork.
- the base plate 4 represents lost formwork, e.g. Wood panels, composite panels, asbestos cement panels, wood cement panels, plastic u. Metal plates and the like. Since the base plate 4 can also form the finished ceiling view as lost formwork, it is expedient to choose a material for the formwork with a structure with which one can achieve the desired final appearance of the ceiling.
- anchors 1 serve as spacers both for the self-supporting reinforcement to be latched in and for the additional reinforcement.
- the anchors 1, e.g. Plastic, metal and wood.
- the reinforced concrete ceiling according to the invention has the advantage that no subordination is required for the final manufacture at the construction site. It can be seen that elements of any size can only be cut to size on the construction site and can be moved by hand, depending on the lifting equipment available.
- elements can also be created in the factory by means of a simple device, which elements can have any length corresponding to the usual commercially available panels and a width which allows easy transportation from the factory to the construction site.
- the anchors 1 used thereon are lowered by means of a holder 10 and on the base plate 4 e.g. glued. You can then raise the bracket 10 for the anchors by one step, as indicated by the double arrow, and place the next base plate on the already finished base plate 4 and provide it with anchors, so that a stack is produced, as shown in FIG. 3 is shown.
- FIGS. 9 and 10 show an anchor 1 with a round anchor base 2.
- the anchor according to FIGS. 9 and 10 is provided with an angular base plate 11 and the anchor head consists of a plate 12 undercut on both sides.
- a variant of FIGS. 9 and 10 is an extruded anchor 1, with the same cross section, wherein the thickness of the plate 12 can be equal to or less than the width of the base plate 11.
- the anchor head consists of two intersecting and undercut plates 13 (cross anchors).
- two parallel base plates 14, 14 ' are provided, on which anchors 15 which are mushroom-shaped are provided in parallel rows and at a distance. These anchors are non-positively connected to the base plates 14, 14 ', be it by gluing, nailing or screws 16.
- the anchors 15 have an annular groove 17 in which the tension rods 18 of, for example, X-shaped lattice girders 19 engage and so on Hold two opposing anchors 15 and thus firmly together with each other on both base plates 14, 14 '.
- the assembly of the formwork can easily be carried out on the construction site in that the X-shaped lattice girders 19 are stretched somewhat in the area of their tension rods 18 and engage over the conical upper part 20.
- the spacing of the rows of anchors can be varied and the steel girders themselves can also be dimensioned as desired.
- the same anchor can therefore be different pick up large steel girders with the appropriate strength.
- Another option is to insert additional reinforcement.

Abstract
Description
Die Erfindung betrifft ein vorgefertigtes Schalungselement für die Herstellung von Strahlbetoncken, mit einer raumseitig ebenen, mit Bewehrung versehenen, als verlorene Schalung dienenden Bauplatte und Stahlgitterträgern als Hauptbewehrung über der Bauplatte, die von an ihr befestigten, mit einem eckigen oder runden Fuß und einem hinterschnittenen Kopfteil versehenen Haltern getragen ist.The invention relates to a prefabricated formwork element for the production of blasted concrete corners, with a room-side flat, with reinforcement, as lost formwork serving building board and steel lattice girders as main reinforcement above the building board, which are attached to it, with an angular or round foot and an undercut headboard provided holders is worn.
Es wurde bereits vorgeschlagen (DE-OS 1911 444), ein Schalungselement dieser Art zur Herstellung von Strahbetondecken mit putzfertiger Untersicht zu verwenden. Es handelt sich dabei im Grunde um eine verlorene Schalungsplatte, auf der Abstandhalter befestigt sind, von denen die Bewehrung getragen wird. Diese Abstandhalter weisen Ausnehmungen zur form-und/oder kraftschlüssigen Halterung der Bewehrung auf, d.h. zur Verbindung zwischen Abstandhalter und Bewehrung.It has already been proposed (DE-OS 1911 444) to use a formwork element of this type for the production of reinforced concrete ceilings with a ready-to-clean bottom view. It is basically a lost formwork panel on which spacers are attached, from which the reinforcement is carried. These spacers have recesses for positive and / or non-positive retention of the reinforcement, i.e. for the connection between spacer and reinforcement.
Die Erfindung zielt nun auf die Schaffung eines Schalungselementes ab, das nach dem Versetzen zu einer Strahlbetondecke ausbetoniert werden kann, u.zw. ohne oder mit nur geringen Unterstellungen. Die jeweils gewünschten Abmessungen sollen gegebenenfalls erst auf der Baustelle festgelegt werden, wo auch Abänderungen kurzfristig erfolgen könnten.The invention now aims to create a formwork element that can be concreted after being moved to a blasted concrete ceiling, etc. without or with only minor assumptions. If necessary, the desired dimensions should only be determined at the construction site, where changes could also be made at short notice.
Ein weiterer Vorteil soll darin bestehen, daß die zu der Baustelle zu transportierenden Elemente hinsichtlich ihres Gewichts relativ leicht sind und mit einfachen mechanischen Hilfsmitteln, z.B. Leichtkränen, versetzt werden können. Bei der Herstellung von Decken im Selbstbau benötigt man häufig nur kleine Deckenelemente, deren Herstellung händisch-ohne Kran-durchgeführt werden kann.Another advantage should be that the elements to be transported to the construction site are relatively light in terms of their weight and with simple mechanical aids, e.g. Light cranes can be moved. In the production of self-made ceilings, one often only needs small ceiling elements, the manufacture of which can be carried out manually without a crane.
Das Wesentliche des erfindungsgemäßen Schalungselementes besteht darin, daß die Halter pilzförmig ausgebildete, mit der Bauplatte kraftschlüssig verbundene Anker sind, wobei die Bewehrungsträger mit ihren Längs- bzw. Zugstäben die Köpfe der pilzförmigen Anker untergreifen oder in an den Ankern ausgebildeten Einschnitten eingreifen, so daß ein selbsttragendes, nach dem Versetzen ohne Unterstützungen ausbetonierbares Schalungselement vorliegt.The essence of the formwork element according to the invention is that the holders are mushroom-shaped anchors that are non-positively connected to the building board, the reinforcement beams with their longitudinal or tension rods engaging under the heads of the mushroom-shaped anchors or engaging in incisions formed on the anchors, so that a there is a self-supporting formwork element that can be concreted without any supports after moving.
Auf der Bauplatte sind also selbsttragende Bewehrungsträger zwischen den Ankerreihen angeordnet, die die Köpfe der Anker untergreifen oder in an den Ankern ausgebildeten Einschnitten eingreifen. Nach dem Einklinken der Bewehrungsträger zwischen zwei parallelen Ankerreihen und dem Aufsetzen dieser nunmehr fest miteinander verbundenen Teile auf entsprechende Stützlager des zu errichtenden Baues erfolgt das Einbringen des Betons auf die Bauplatte als sogenannte verlorene Schalung.Self-supporting reinforcement beams are thus arranged on the building board between the rows of anchors, which engage under the heads of the anchors or engage in incisions formed on the anchors. After the reinforcement beams have been latched in between two parallel rows of anchors and these parts, which are now firmly connected to each other, have been placed on corresponding support bearings of the building to be erected, the concrete is introduced onto the building board as so-called lost formwork.
Je nach Wunsch können die Bewehrungsträger statisch so ausgeführt werden, daß entweder gar keine oder nur geringfügige Unterstellungen anzuordnen sind, um die Stahlbetondeckewährend der Abbindezeit des Betons ausreichend abzustützen.If required, the reinforcement beams can be designed statically in such a way that either no or only minor supports are to be arranged in order to adequately support the reinforced concrete slab during the setting time of the concrete.
Mit Vorteil werden die Schalungsteile der Decke bereits im Werk zusammengesetzt und danach aufeinander gestapelt und gelagert.Advantageously, the formwork parts of the ceiling are assembled in the factory and then stacked and stored on top of each other.
Soweit erforderlich, können in die Einschnitte der Anker auch Stäbe einer Zusatzbewehrung eingelegt werden. Diese Bewehrung kann sowohl im Werk als auch erst auf der Baustelle verlegt werden. Somit verfügt man über ein leicht zu versetzendes und ohne Schwierigkeiten zu transportierendes Element, das aus einer verlorenen Schalung, der erforderlichen Deckenbewehrung und den erwähnten pilzförmigen Ankern besteht, und in das dann-nach dem Versetzen auf der Baustelle-nurmehr der erforderliche Beton eingebracht werden muß, um die fertige Stahlbetondecke zu erhalten.If necessary, bars of additional reinforcement can also be inserted into the incisions of the anchors. This reinforcement can be installed both in the factory and only on the construction site. So you have an easy to move and easy to transport element that consists of lost formwork, the required ceiling reinforcement and the aforementioned mushroom-shaped anchors, and into which - after moving to the construction site - only the required concrete has to be poured to get the finished reinforced concrete floor.
Sobald der Versetzvorgang abgeschlossen ist, können wie bei herkömmlichen Ortbetondecken die Installationen eingelegt und die Betonierarbeiten durchgeführt werden.As soon as the moving process is complete, the installations can be inserted and the concreting work carried out, as with conventional in-situ concrete ceilings.
Die Herstellung einer solchen Betonwand ist dann etwas problematisch, wenn sie zur Bildung von schrägen Decken, z.B. bei Dachausbauten verwendet werden soll, wobei eine "verlorene Schalung" aus beliebigem Material, die zugleich auch die fertige Wandoberfläche darstellt, zur Anwendung gelangt. In diesem Fall sollte die "verlorene Schalung" aus zwei die fertige Wand- bzw. Deckenoberflächen bildenden Grundplatten bestehen, und es wäre ferner von Vorteil, die "verlorene Schalung" für eine solche Wand oder schräge Decke in zwei Teilen herstellen zu können, um sie leicht zwischenlagern, auf das gewünschte Format zuschneiden, transportieren und erst zu einem späteren Zeitpunkt zusammenzufügen zu können. Dabei bestünde auch der Vorteil, daß man je nach den Anforderungen in die Schalung Ausschnitte und Öffnungen vorsehen sowie Leitungen oder Zusatzbewehrungen einlegen könnte und dies unabhängig von dem eigentlichen Setzvorgang der Schalung auf der Baustelle.The production of such a concrete wall is somewhat problematic if it is used to form sloping ceilings, e.g. to be used in roof extensions, whereby a "lost formwork" of any material, which also represents the finished wall surface, is used. In this case, the "lost formwork" should consist of two base plates which form the finished wall or ceiling surface, and it would also be advantageous to be able to produce the "lost formwork" for such a wall or sloping ceiling in two parts in order to be able to produce it can be stored temporarily, cut to the required format, transported and only put together at a later point in time. There would also be the advantage that, depending on the requirements, cutouts and openings could be provided in the formwork, and lines or additional reinforcements could be inserted, regardless of the actual setting process of the formwork on the construction site.
Um dies durchführen zu können, wird erfindungsgemäß in weiterer Ausgestaltung der Erfindung ein vorgefertigtes "verlorenes Schalungselement" für die Herstellung von insbesondere geneigten, mit einer aus selbsttragenden Bewehrungsträgern, vorzugsweise Gitterträgern, bestehende Bewehrung versehenen Stahlbetondecken mit zwei die fertige Wand- bzw. Deckenoberfläche bildenden Grundplatten vorgeschlagen, dessen Besonderheit darin besteht, daß auf den Grundplatten in parallelen Reihen in Abständen vorzugsweise im Querschnitt pilzförmig ausgebildete Anker aufgesetzt und mit den Grundplatten kraftschlüssig verbunden sind, und daß die Längs- bzw. Zugstäbe der zugleich als Abstandhalter dienenden Bewehrungsträger die Köpfe der Anker beider Grundplatten untergreifen oder in an den Ankern ausgebildeten Einschnitten eingreifen.In order to be able to do this, according to the invention, in a further embodiment of the invention, a prefabricated "lost formwork element" is used for the production of, in particular, inclined, reinforced concrete ceilings provided with self-supporting reinforcement beams, preferably lattice girders, with two base plates forming the finished wall or ceiling surface proposed, the special feature of which is that mushroom-shaped anchors are placed on the base plates in parallel rows at intervals, preferably in cross section, and are non-positively connected to the base plates, and that the longitudinal or tension rods of the reinforcement beams, which also serve as spacers, are the heads of the anchors of both Reach under base plates or engage in incisions formed in the anchors.
Nachstehend soll die Erfindung anhand der Zeichnungen näher erläutert werden, in denen Fig. 1 eine Grundplatte zeigt, auf der rasterartig pilzförmig ausgebildete Anker in parallelen Reihen aufgebracht sind. Fig. 2 veranschaulicht perspecktivisch eine Vorrichtung, mit der die Anker auf eine Grundplatte maschinell aufgesetzt werden können. Fig. 3 zeigt aufeinander gestapelte Grundplatten samt aufgesetzten Ankern für eine raumsparende Lagerung oder für den Transport zur Baustelle. Fig. 4 ist die perspektivische Darstellung eines versetzfertigen Elementes. Die Fig. 5-12 zeigen in Ansicht bzw. in Draufsicht verschiedene Ausführungsformen von Ankern. Fig. 13 veranschaulicht eine weitere Ausführungsform der Erfindung.The invention will be explained in more detail below with reference to the drawings, in which FIG. 1 shows a base plate, on which anchors designed in the form of mushrooms are attached in parallel rows. Fig. 2 illustrates perspective an apparatus with which the anchor on a Base plate can be placed mechanically. Fig. 3 shows stacked base plates with attached anchors for space-saving storage or for transport to the construction site. Fig. 4 is a perspective view of a ready-to-move element. 5-12 show different embodiments of anchors in a view or in plan view. 13 illustrates another embodiment of the invention.
Die pilzförmig ausgebildeten Anker 1 bestehen im wesentlichen aus einem plattenförmigen Fuß 2, dessen Unterseite glatt, gerillt bzw. strukturiert oder auch gelocht sein kann, und eventuell Stife 3 aufweist, um den auf eine Schalungsplatte 4 aufgesetzten Anker 1 mit der Platte während des Leimvorganges in horizontaler Richtung gegen Verschieben zu sichern. Anstelle dieser beiden Stifte (Nägel) kann der Anker auch ein Loch aufweisen, durch welches man einen Nagel schlägt.The mushroom-
Die Anker 1 werden entsprechend dem auf der Grundplatte 4 in Fig. 1 angedeuteten Raster in parallelen Reihen versetzt, z.B. nach Aufbringen eines Klebers auf der Ankerunterseite mit einem Hammer auf die Grundplatte 4 aufgeklopft, wobei die Stifte 3 des Ankers in das Material der Platte eindringen und so eine genaue Fixierung ermöglichen. Entsprechend der pilzförmigen Ausgestaltung der Anker weisen diese einen verjüngten Zwischenteil bzw. Einschnitt 5 auf, der sich am oberen Ende wieder erweitert und einen pilzförmigen Kopf 6 bildet.The
Je nach dem Material, aus dem die Anker 1 bestehen, können diese gegebenenfalls auch mit der Grundplatte 4 verschweißt oder auch verschraubt werden.Depending on the material from which the
Zwischen den Ankerreihen wird eine freigespannte Bewehrung, z.B. in Form eines Gitterträgers 7, eingebracht, wie dies am besten der Fig. 4 zu entnehmen ist. Dieses Einbringen der Bewehrung erfolgt zweckmäßig durch Einklinken der unteren, die Zugkräfte übertragenden Längsstäbe 8 des Gitterträgers. Es versteht sich, daß jeder geeignet ausgebildete Gitterträger Verwendung finden kann. Entsprechend der Belastung beim Einbringen des Betons auf die verlorene Schalung sind die Abstände zwischen den Ankern 1 in Längs- und Querrichtung zu bemessen.Free-spanned reinforcement, e.g. in the form of a
Als Grundplatte 4, die eine verlorene Schalung darstellt, eignen sich die verschiedensten Materialien, z.B. Holzplatten, Verbundplatten, Asbest-Zementplatten, Holz-Zementplatten, Kunststoffu. Metallplatten u.dgl.. Da die Grundplatte 4 als verlorene Schalung zugleich die fertige Deckenuntersicht bilden kann, ist es zweckmäßig, für die Schalung ein Material mit einer Struktur zu wählen, mit der man das gewünschte endgültige Aussehen der Decke erzielen kann.A wide variety of materials are suitable as the base plate 4, which represents lost formwork, e.g. Wood panels, composite panels, asbestos cement panels, wood cement panels, plastic u. Metal plates and the like. Since the base plate 4 can also form the finished ceiling view as lost formwork, it is expedient to choose a material for the formwork with a structure with which one can achieve the desired final appearance of the ceiling.
Für größere Deckenspannweiten bzw. Deckenbelastungen kann auch eine Zusatzbewehrung, z.B. aus Baustahlmatten, neben den Längsstäben 8 der Gitterträger 7 eingelegt werden. Die Anker 1 dienen in diesem Falls zugleich als Abstandhalter sowohl für die einzuklinkende selbsttragende Bewehrung als auch für die Zusatzbewehrung.For larger slab spans or slab loads, additional reinforcement, e.g. of structural steel mats, in addition to the
Es versteht sich von selbst, daß für die Herstellung der Anker 1 die verschiedensten Materialien herangezogen werden können, z.B. Kunststoff, Metall und Holz.It goes without saying that a wide variety of materials can be used for the manufacture of the
Die erfindungsgemäße Stahlbetondecke ermöglicht den Vorteil, daß keine Unterstellung bei der endgültigen Herstellung an der Baustelle erforderlich ist. Es ist zu erkennen, daß Elemente von beliebiger Größe erst auf der Baustelle zugeschnitten und je nach vorhandenem Hebezeug, also auch händisch, versetzt werden können.The reinforced concrete ceiling according to the invention has the advantage that no subordination is required for the final manufacture at the construction site. It can be seen that elements of any size can only be cut to size on the construction site and can be moved by hand, depending on the lifting equipment available.
Wie in Fig. 2 dargestellt ist, kann man auch Elemente mittels einer einfachen Vorrichtung im Werk erstellen, wobei diese Elemente eine beliebige Länge entsprechend üblicher im Handel erhältlicher Platten und eine Breite, die ein einfaches Transportieren vom Werk zur Baustelle zuläßt, aufweisen können. Auf die auf einen Tisch 9 aufgelegte Grundplatte 4 werden mittels einer Halterung 10 die auf dieser eingesetzten Anker 1 abgesenkt und auf der Grundplatte 4 z.B. aufgeklebt. Man kann dann die Halterung 10 für die Anker um eine Stufe heben, wie dies der Doppelpfeil andeutet, und auf die bereits fertig bestückte Grundplatte 4 die nächste Grundplatte auflegen und diese mit Ankern versehen, sodaß sich ein Stapel ergibt, wie er in Fig. 3 dargestellt ist.As shown in Fig. 2, elements can also be created in the factory by means of a simple device, which elements can have any length corresponding to the usual commercially available panels and a width which allows easy transportation from the factory to the construction site. On the base plate 4 placed on a table 9, the
Die Fig. 7 und 8 zeigen einen Anker 1 mit einem runden Ankerfuß 2. Der Anker gemäß Fig. 9 und 10 ist mit einer eckigen Fußplatte 11 versehen und der Ankerkopf besteht aus einer beidseitig hinterschnittenen Platte 12. Eine Variante der Fig. 9 und 10 ist ein extrudierter Anker 1, mit gleichem Querschnitt, wobei die Dicke der Platte 12 gleich oder kleiner als die Breite der Fußplatte 11 sein kann. Gemäß einer weiteren Variante (Fig. 11, 12) besteht der Ankerkopf aus zwei sich kreuzenden und hinterschnittenen Platten 13 (Kreuzanker).7 and 8 show an
Wie der Fig. 13 zu entnehmen ist, sind zwei parallele Grundplatten 14, 14' vorgesehen, auf denen im parallelen Reihen und im Abstand pilzförmig ausgebildete Anker 15 vorgesehen sind. Diese Anker sind mit den Grundplatten 14, 14' kraftschlüssig verbunden, sei es durch Kleben, Nageln oder Schrauben 16. Die Anker 15 haben im vorliegenden Fall eine ringförmige Nut 17, in denen die Zugstäbe 18 von beispielsweise X-förmigen Gitterträgern 19 eingreifen und so je zwei einander gegenüberliegende Anker 15 und damit bei beiden Grundplatten 14, 14' fest miteinander zusammenhalten.As can be seen in FIG. 13, two
Das Zusammenfügen der Schalung kann auf der Baustelle leicht dadurch ausgeführt werden, daß die X-förmigen Gitterträger 19 im Bereich ihrer Zugstäbe 18 etwas gedehnt und über den konische ausgebildeten Oberteil 20 einrasten.The assembly of the formwork can easily be carried out on the construction site in that the
Es ist ersichtlich, daß man je nach Erfordernis, z.B. entsprechend den statischen Bedingungen, den Abstand der Ankerreihen variieren und auch die Stahlträger selbst beliebig bemessen kann. Die gleichen Anker können somit verschieden große und in ihrer Festigkeit entsprechend bemessene Stahlträger aufnehmen. Eine weitere Möglichkeit besteht im Einlegen einer Zusatzbewehrung.It can be seen that depending on the requirements, for example the static conditions, the spacing of the rows of anchors can be varied and the steel girders themselves can also be dimensioned as desired. The same anchor can therefore be different pick up large steel girders with the appropriate strength. Another option is to insert additional reinforcement.
Weitere sich aus dem erfindungsgemäßen Vorschlag ergebende Effekte sind darin zu sehen, daß man im Werk lediglich die Grundplatten 14, 14' mit den aufgesetzten Ankern 15 herstellt und vorrätig hält. Je nach Bedarf kann man derartige Grundplatten mit Ausschnitten versehen und auch hinsichtlich ihrer äußeren Abmessungen zurechtschneiden. Die gitterförmigen Träger 19 könnten bereits im Werk auf eine der Platten aufgesetzt werden. Es ergibt sich somit eine erhebliche Erleichterung in der Lagerhaltung, da man vorbereitete Standardgrößen von Grundplatten leicht stapeln kann. Auf der Baustelle ist das Versetzen mit einfachen Hebezeugen ohne Schwierigkeiten durchführbar. Nach dem Einbringen des Betons liegt eine Stahlbetondecke vor, deren "verlorene Schalung" die Außenseiten der Decke bildet.Further effects resulting from the proposal according to the invention can be seen in the fact that only the
