Description

Die Erfindung betrifft einen Wegkörper gemäß den oberbegrifflichen Merkmalen des Anspruches 1. Ein derartiger Aufbau ist aus der GB-A-2 300 009 bekannt.The invention relates to a path body according to the preamble features of claim 1. Such a structure is known from GB-A-2 300 009 known.

Wege, insbesondere Straßen oder Plätze müssen in der Regel wegen der hohen Gewichtsbelastung durch die darüber fahrenden Fahrzeuge befestigt werden z.B. mit Pflasterbelägen. Durch den Unterbau soll zudem eine stabile Unterlage für die durch die Befahrung auftretenden hohen Belastungen des Wegkörpers, insbesondere bei stark frequentierten Straßen oder Plätzen geschaffen werden. Aus diesen Gründen sind Wegekörper in der Regel mehrschichtig aufgebaut und zudem zur Erleichterung des Wasserabflusses zu den Rändern hin abgesenkt. Der Unterbau hat dabei verschiedene Aufgaben zu erfüllen. Eine der Hauptaufgaben ist es, dass Niederschläge möglichst rasch abtransportiert werden, um so das Eindringen und den Verbleib von eingedrungenem Wasser zu verringen und um somit die dadurch entstehenden Schäden am Wegkörper und der Deckschicht zu vermeiden.Ways, in particular roads or squares, usually have to be fastened because of the high weight load by the vehicles driving over them, e.g. with pavement. The substructure is also intended to create a stable underlay for the high loads of the roadway body that occur as a result of driving, especially in heavily frequented streets or squares. For these reasons, pathway body are usually constructed multi-layered and also lowered to facilitate the flow of water to the edges. The substructure has to fulfill different tasks. One of the main tasks is to remove precipitation as quickly as possible in order to reduce the penetration and whereabouts of penetrated water and thus to avoid the resulting damage to the pathway and the cover layer.

Als unterste Schicht ist meist eine verdichtete Schicht aus Kies/Schotter mit ca. 40-100 cm Aufbau vorgesehen, auf der eine Ausgleichsschicht aufgetragen wird, wie dies im Dokument DE 203 05 149 U1 beschrieben ist. Die Ausgleichsschicht (= Verlegebett) stellt die Auflagefläche für die Deckschicht bereit und gibt deren Form vor. Als Deckschicht wird ein Fahrbelag aufgebracht, auf dem beispielsweise die Fahrzeuge bewegt werden. Bekannte Wegkörper sind somit in der Regel bis zum Baugrund 80 cm tief und durch Rütteln hochverdichtet, um die nötige Tragfähigkeit und Frostsicherheit bieten zu können. Der Fahrbelag besteht häufig aus Asphalt oder Pflastersteinen, die eine durchgängige Fläche bilden.As the lowest layer is usually a compacted layer of gravel / gravel with about 40-100 cm structure provided on which a leveling layer is applied, as in the document DE 203 05 149 U1 is described. The leveling layer (= laying bed) provides the support surface for the cover layer and specifies its shape. As cover layer, a driving surface is applied, on which, for example, the vehicles are moved. Known path body are thus usually up to the ground 80 cm deep and highly compacted by shaking to provide the necessary capacity and frost resistance can. The driving surface often consists of asphalt or paving stones, which form a continuous surface.

Nachteil des bekannten Wegkörpers ist insbesondere dessen aufwändige Herstellung durch die erforderliche Verdichtung der Schichten, der hohe Materialaufwand und das daraus resultierende hohe Gewicht. Dies gilt auch für den Aufbau gemäß der GB-A-2 300 009 , da dort Stahlmatten eingelegt und mit Beton vergossen werden. Bei der DE 20 60 274 A1 werden sogar durchgängige Stahlplatten verwendet. Zudem wird durch die Befestigung der Untergrund relativ hoch verdichtet, wodurch die Sickerfähigkeit stark reduziert wird. Eine Kanalisation oder Entwässerung wird dadurch unumgänglich. Dies führt zu weiteren erheblichen Kosten, da neben der Flächenentwässerung auch Ablaufschächte und Kanalrohre angelegt werden müssen.Disadvantage of the known path body is in particular its complex production by the required densification of the layers, the high cost of materials and the resulting high weight. This also applies to the structure according to the GB-A-2 300 009 because there steel mats are inserted and cast with concrete. In the DE 20 60 274 A1 even continuous steel plates are used. In addition, the substrate is relatively highly compressed by the attachment, whereby the seepage is greatly reduced. A sewer or drainage is inevitable. This leads to further considerable costs, since in addition to the surface drainage also drain shafts and sewer pipes must be created.

Aufgabe der vorliegenden Erfindung ist daher, einen kostengünstigen, leicht zu erstellenden Wegkörper, insbesondere für Straßen und Plätze bereitzustellen, der planeben, wasserdurchlässig, stabil und langlebig ist und vorzugsweise auch das Gewicht des Aufbaus durch ein lastverteilendes System unter dem Pflasterbelag reduziert.Object of the present invention is therefore to provide a low-cost, easy to create path body, especially for roads and squares, which is level, permeable to water, stable and durable and preferably also reduces the weight of the structure by a load-distributing system under the pavement.

Diese Aufgabe wird gelöst durch einen Wegkörper nach Anspruch 1. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a path body according to claim 1. Advantageous embodiments are the subject of the dependent claims.

Der Wegkörper weist dabei einen geschichteten Aufbau auf, der aus mehreren Schichten besteht (Verlegebett für Pflaster / Gitter / Hartschaum, ggf. Geotextilien). Über dem Untergrund ist eine Isolationsschicht/Hilfstragschicht aus Hartschaumelementen, die mit Fugen voneinander beabstandet sind, vorgesehen, darüber eine Tragschicht aus lastverteilenden Gitterelementen und über dieser eine Deckschicht, die vorzugsweise als Fahrbelag ausgebildet ist, auf dem sich die Fahrzeuge bewegen, insbesondere Pflasterbeläge. Die Verwendung von Hartschaumelementen stellt sicher, dass der Wegkörper die aufgabengemäßen Anforderungen hinsichtlich Frostsicherheit, Stabilität und Langlebigkeit erfüllt und zudem durch die vorgesehenen Fugen Wasserdurchlässigkeit garantiert. Die Verwendung von Hartschaumelementen ermöglicht auch den planebenen Aufbau des Weges ohne die übliche konvexe Wölbung zu den Rändern herkömmlicher Wege, die zur Ableitung des Wassers notwendig ist. Dadurch wird durch den erfindungsgemäßen Wegkörper eine kostengünstige Alternative zu bekannten Wegkörpern erstellt. Ein weiterer Vorteil dieses Wegkörpers liegt in der erheblich reduzierten Stärke der einzelnen Schichten, was zu einem wesentlichen geringeren Aufwand bei der Erstellung des gesamten Wegkörpers führt. Zudem wird eine Gewichtsreduzierung und die Einsatzmöglichkeit bei besonders schlechten (nicht tragfähigen) Untergründen erzielt, insbesondere auch ein Absinken der Tragschicht verhindert.The path body has a layered structure that consists of several layers (laying bed for plaster / grid / hard foam, possibly geotextiles). Above the ground, an insulation layer / auxiliary layer of hard foam elements, which are spaced apart from each other, provided, above a support layer of load-distributing grid elements and above this a cover layer, which is preferably designed as a driving surface on which move the vehicles, in particular pavement. The use of hard foam elements ensures that the body of the road fulfills the requirements for frost protection, stability and longevity, and also guarantees water permeability through the provided joints. The use of hard foam elements also allows the planar construction of the path without the usual convex curvature to the edges of conventional ways, which is necessary for the discharge of the water. As a result, a cost-effective alternative to known path bodies is created by the path body according to the invention. Another advantage of this way body lies in the significantly reduced strength of the individual layers, which leads to a significantly lower effort in the creation of the entire path body. In addition, a reduction in weight and the possibility of using particularly poor (unsustainable) surfaces is achieved, in particular prevents a decrease in the support layer.

Die Verwendung von Elementen aus geschlossenzelligem, wasserabweisendem Hartschaum, insbesondere aus dichtem Polystyrol erhöht die Langlebigkeit des Wegkörpers durch die direkte Ableitung des anfallenden Wassers.The use of elements made of closed-cell, water-repellent hard foam, in particular of dense polystyrene, increases the longevity of the pathway body by the direct discharge of the resulting water.

Die Hartschaumelemente werden mit Fugen von 1 bis 10 cm Breite verlegt, um eine optimale Wasserableitung zu gewährleisten. Als bevorzugte Fugenbreite gelten 3 bis 5 cm. Bei der Anlage des Wegkörpers soll zudem der Anteil der Fugen 2 bis 8 % der Gesamtwegfläche ausmachen, wobei sich 3 bis 5 % als besonders günstig erwiesen haben. Eine Verfüllung der Fugen mit Partikelmaterial erhöht die Stabilität der Hilfstragschicht , weil eine Verschiebung der Hartschaumelemente verhindert wird, und begünstigt darüber hinaus ebenfalls die Drainage des anfallenden Wassers.The hard foam elements are laid with joints of 1 to 10 cm width to ensure optimum drainage. The preferred joint width is 3 to 5 cm. When planting the path body, the proportion of joints should also account for 2 to 8% of the total area of the road, with 3 to 5% proving particularly favorable. Filling of the joints with particulate material increases the stability of the auxiliary support layer, because a displacement of the rigid foam elements is prevented, and also favors the drainage of the accumulating water.

Die Gitterelemente der Tragschicht werden so verlegt, dass die ihre Gitterstruktur bildenden Stege einen Winkel von 30 bis 60°, vorzugsweise 45°, zu den Seitenkanten der darunter liegenden Hartschaumelemente, die in der Regel plattenförmig ausgebildet sind, einnehmen. Es wird damit bei guter Lastverteilung die geringst mögliche Überlagerung zwischen den Gitterelementen der Tragschicht und den Fugen zwischen den Hartschaumelementen erreicht, um so die bestmögliche Wasserabführung zu gewährleisten.The grid elements of the support layer are laid so that the webs forming their grid structure occupy an angle of 30 to 60 °, preferably 45 °, to the side edges of the underlying rigid foam elements, which are generally plate-shaped. It is thus achieved with good load distribution, the lowest possible overlap between the grid elements of the support layer and the joints between the hard foam elements, so as to ensure the best possible drainage.

Die über Nuten und Federn oder Horizontalverzahnungen miteinander verbundenen Gitterelemente, die die Tragschicht bilden, leiten die auftretenden Kräfte sicher ab und verteilen diese über eine große Fläche. Außerdem wird durch die Verfüllung der Gitterelemente mit Partikelmaterial, insbesondere Split und Riesel, eine schnelle Abführung des eingedrungenen Wassers erreicht. Die auf der Unterseite vorgesehenen Durchbrüche der Gitterelemente begünstigen den Abfluss des anfallenden Wassers und sichern somit ebenfalls die Langlebigkeit des erfindungsgemäßen Wegkörpers.The interconnected via grooves and springs or horizontal gears grid elements that form the support layer, derive the forces occurring safely and distribute them over a large area. In addition, a rapid removal of the penetrated water is achieved by the backfilling of the grid elements with particulate material, in particular split and trickle. The measures provided for on the underside breakthroughs of the grid elements favor the outflow of the accumulating water and thus also ensure the longevity of the path body according to the invention.

Nachstehend wird die Erfindung anhand der Figuren näher erläutert und beschrieben. Es zeigen:

  • Fig. 1 einen erfindungsgemäßen Wegkörper für Straßen in schematischer Schnittdarstellung;
  • Fig. 2 eine Perspektivansicht des Wegkörper-Aufbaus; und
  • Fig. 3 ein Ausführungsbeispiel eines Wegkörpers in perspektivischer Darstellung.
The invention will be explained and described in more detail with reference to FIGS. Show it:
  • Fig. 1 a road body according to the invention for roads in a schematic sectional view;
  • Fig. 2 a perspective view of the body structure; and
  • Fig. 3 an embodiment of a path body in perspective view.

Im Ausführungsbeispiel der Fig. 1 sind zwei Schichten über einer Hilfstragschicht 101 vorgesehen, nämlich eine aus miteinander verzahnten Gitterelementen 130 gebildete Tragschicht 102 und ein Fahrbelag als Deckschicht 103. Die Verfüllung der Gitterelemente 130 der Tragschicht 102 mit Partikelmaterial und die auf der Unterseite der Gitterelemente 130 vorgesehenen Durchbrüche 133 gewährleisten eine optimale Drainage bzw. Regulation des anfallenden Wassers in derHilfstragschicht 101 aus Hartschaumelementen 110. Die Hartschaumelemente 110 der Hilfstragschicht 101 sind mit Fugen verlegt, die der Wasserableitung dienen und somit zur Vermeidung von durch Wasser verursachten Schäden beitragen. Die Deckschicht 103 wird in diesem Ausführungsbeispiel von einem durchgehenden Belag gebildet.In the embodiment of Fig. 1 two layers are provided over an auxiliary carrier layer 101, namely a grid element 130 made up of intermeshed gratings Supporting layer 102 and a driving surface as cover layer 103. The backfilling of the grid elements 130 of the support layer 102 with particulate material and the openings 133 provided on the underside of the grid elements 130 ensure optimum drainage or regulation of the accumulated water in the auxiliary layer 101 of hard foam elements 110. The hard foam elements 110 the auxiliary carrier layer 101 are laid with joints, which serve to drain water and thus contribute to the prevention of damage caused by water. The cover layer 103 is formed in this embodiment by a continuous covering.

Fig. 2 und 3 zeigen den Aufbau des erfindungsgemäßen Wegkörpers in perspektivischer Darstellung, wobei Fig. 2 dem Aufbau in Fig. 1 entspricht, während in Fig. 3 der Wegkörper hier noch zusätzliche Schichten besitzt, nämlich eine obere Verlegschicht 206 zwischen Deckschicht 203 und Tragschicht 202 sowie eine untere Verlegschicht 205 zwischen Tragschicht 202 und Hilfstragschicht 201. Die Hartschaumelemente 210 der Hilfstragschicht 201 sind ebenfalls auf einer Verlegschicht 204 aufgebracht. FIGS. 2 and 3 show the structure of the path body according to the invention in a perspective view, wherein Fig. 2 the construction in Fig. 1 corresponds while in Fig. 3 the body also has additional layers here, namely an upper layer 206 between the outer layer 203 and the base layer 202 and a lower layer 205 between the base layer 202 and the auxiliary layer 201. The hard foam elements 210 of the auxiliary layer 201 are also applied to an installation layer 204.

Die Deckschicht 203 besteht hier aus Pflastersteinen. Die Deckschicht 203 wird in diesem Ausführungsbeispiel von einem Bordstein mit dahinterliegender Rückenstütze 240 eingefasst, der dazu dient, den Weg zu begrenzen und das Pflaster in seiner ursprünglichen Position zu halten. Diese Stütze in Art eines Ringankers besteht aus Beton und reicht bis in das darunter liegende Gitterelement 230, um die notwendige Verankerung und damit seitliche Stabilität herzustellen. Das Pflaster wird auf der hier 3 bis 5 cm starken oberen Verlegschicht 206 verlegt, die in der Lage ist, leichte Unebenheiten zu nivellieren. Unter der oberen Verlegschicht 206 befindet sich die Tragschicht 202, die aus mit einem Partikelmaterial verfüllten Gitterelementen 230 besteht, die auf der unteren Verlegschicht 205 ausgelegt sind. Die Gitterelemente 230 verfügen auf der Unterseite über Durchbrüche (nicht dargestellt) und gewährleisten dadurch eine optimale Drainage des anfallenden Wassers im Mittelbau des Wegkörpers.The cover layer 203 consists here of paving stones. The cover layer 203 is bordered in this embodiment by a curb with underlying back support 240, which serves to limit the way and to hold the patch in its original position. This support in the form of a ring anchor is made of concrete and extends into the underlying grid element 230 in order to produce the necessary anchoring and thus lateral stability. The plaster is laid on the here 3 to 5 cm thick top layer 206, which is able to level slight bumps. Below the upper layer 206 is the base layer 202, which consists of grid elements 230 filled with a particulate material, which are laid out on the lower layer 205. The grid elements 230 have on the bottom through openings (not shown) and thereby ensure optimum drainage of the accumulating water in the central structure of the path body.

Die Hartschaumelemente 210 werden mit Fugen von 1 bis 10 cm, insbesondere 3 bis 5 cm, verlegt. Ihre Seitenkanten nehmen einen Winkel α von 45° zur Hauptrichtung der Stege der Gitterelemente 230, die die Tragschicht 202 bilden, ein. Im Ausführungsbeispiel werden quadratische Gitterelemente verwendet. Die Verwendung von recht- bis vieleckigen Gitterelementen zur Bildung der Tragschicht ist ebenfalls möglich.The hard foam elements 210 are laid with joints of 1 to 10 cm, in particular 3 to 5 cm. Their side edges take an angle α of 45 ° to the main direction of the webs of the grid elements 230, which form the support layer 202, a. in the Embodiment square grid elements are used. The use of rectangular to polygonal grid elements to form the base layer is also possible.

Aufgrund ihrer Beschaffenheit aus einem geschlossenzelligen, wasserabweisenden Hartschaum, wie insbesondere hochdichtem Polystyrol, nehmen die Hartschaumelemente keine Feuchtigkeit auf, sondern leiten dieses vollständig ab. Da die Fugen zwischen den Hartschaumelementen mit Partikelmaterial, insbesondere Split oder Riesel, verfüllt sind, können diese das abgeführte Wasser effizient in auf beiden Seiten des Weges vorgesehene Drainagerohre 260 ableiten. Der beschriebene Aufbau ermöglicht es, den Wegkörper relativ wasserfrei zu halten, wodurch von dauerhaft anstehendem Stauwasser verursachte Schäden am gesamten Wegaufbau auf ein Minimum reduziert werden.Due to their nature of a closed-cell, water-repellent rigid foam, in particular high-density polystyrene, take the hard foam elements no moisture, but derive this completely. Since the joints between the rigid foam elements are filled with particulate material, in particular split or trickle, these can efficiently drain the discharged water into drainage pipes 260 provided on both sides of the path. The structure described makes it possible to keep the path body relatively free of water, which caused by permanently pending backwater damage to the entire path structure are reduced to a minimum.

Die Hartschaumelemente 210 (entsprechend den Hartschaumelementen 110 in Fig. 1 und 2) sind auf einer ca. 4 cm dicken Verlegschicht 204 aufgebracht. Diese gleicht vorhandene Unebenheiten des Untergrundes aus und ermöglicht eine planebene Verlegung der Hartschaumelemente 210. Im zweiten Ausführungsbeispiel ist der gesamte Wegeaufbau mit einer weiteren Betoneinfassung 270 zum Schutz der Drainagerohre 260 versehen.The foam elements 210 (corresponding to the rigid foam elements 110 in FIG Fig. 1 and 2 ) are applied to an approximately 4 cm thick laying layer 204. This compensates for existing unevenness of the substrate and allows a flat laying of the rigid foam elements 210. In the second embodiment, the entire path structure is provided with a further concrete enclosure 270 for protecting the drainage pipes 260.

Durch die vorgeschlagene Neuerung wird eine einfache und kostengünstige Möglichkeit des Wege- und Platzbaus geschaffen. Durch den erfindungsgemäßen Wegkörper wird somit der aufwändige Aufbau herkömmlicher Wegkörper, die zum Teil eine Stärke von mehr als 80 cm aufweisen, stark vereinfacht und reduziert. Durch die Verwendung von Hartschaumelementen 110, 210 als Hilfstragschicht 101 entfällt die Notwendigkeit zur aufwändigen Verdichtung der unteren Wegschichten. Zudem wird aufgrund von Drainagefugen zwischen den Hartschaumelementen, der ansonsten unerlässliche Drainage- und Kanalisationsaufwand für herkömmliche Wegekörper, überflüssig bzw. auf ein Minimum reduziert.The proposed innovation creates a simple and cost-effective way of path and space. As a result of the inventive travel body, the complex structure of conventional travel bodies, some of which have a thickness of more than 80 cm, is greatly simplified and reduced. The use of hard foam elements 110, 210 as the auxiliary carrier layer 101 eliminates the need for complicated compaction of the lower path layers. In addition, due to drainage joints between the hard foam elements, the otherwise essential drainage and drainage for conventional way body, superfluous or reduced to a minimum.
