Abstract

Une natte (12) élastomère extrudée en une seule pièce ou composée de sections longitudinales séparées (11, 13), qui sert à recouvrir un joint de dilatation d'une chaussée comprend, sur les bords parallèles au joint, des nervures (17) qui font saillie vers le bas et s'engagent par liaison de forme dans une rainure, ouverte vers le haut, d'un profilé marginal ou intermédiaire (4), laissant un espace résiduel vide (21) entre les nervures et la périphérie inférieure de la rainure. Cet espace résiduel (21) est rempli avec une masse de scellement (20) en résine synthétique élastomère ayant approximativement la même dureté que la natte (12), cette masse étant coulée d'en haut à travers des orifices ou des fentes (26) ménagés dans la natte (12) qui forment des canaux de coulée, entièrement remplis eux aussi par la masse de scellement, ce qui permet d'établir une liaison permanente entre les nervures (17) et les profilés de retenue (4) correspondants. Lorsque la natte (12) se compose de sections longitudinales séparées, les fentes de coulée (26) sont formées par les joints entre les sections (11, 13). Une bande (10) qui chevauche la couche d'isolation (9) de la chaussée est moulée sur le bord de la natte, ou sur sa section marginale (11).An elastomeric mat (12) extruded in one piece or composed of separate longitudinal sections (11, 13), which serves to cover an expansion joint of a roadway comprises, on the edges parallel to the joint, ribs (17) which protrude downwards and formally engage in a groove, open upwards, of a marginal or intermediate profile (4), leaving a residual empty space (21) between the ribs and the lower periphery of the groove. This residual space (21) is filled with a sealing mass (20) of elastomeric synthetic resin having approximately the same hardness as the mat (12), this mass being poured from above through holes or slits (26). formed in the mat (12) which form pouring channels, also completely filled with the sealing compound, which makes it possible to establish a permanent connection between the ribs (17) and the corresponding retaining profiles (4). When the mat (12) consists of separate longitudinal sections, the tapping slots (26) are formed by the joints between the sections (11, 13). A strip (10) which overlaps the insulation layer (9) of the pavement is molded on the edge of the mat, or on its marginal section (11).

Description

Beschreibungdescription
Vorrichtung zur Überbrückung von DehnungsfugenDevice for bridging expansion joints
Die Erfindung betrifft eine Vorrichtung zur Über¬ brückung von Dehnungsfugen in Fahrbahnen, mit einer die Fuge überbrückenden extrudierten Matte aus ela- stomerem Werkstoff, deren zur Fuge parallele Längs¬ ränder jeweils in einer nach oben offenen Nut eines randseitigen Halteprofils befestigt sind, wozu an der Mattenunterseite Rippen angeformt sind, die in die Nut formschlüssig eingreifen und diese bis auf einen verbleibenden Verankerungsraum im wesentlichen aus- fül len.The invention relates to a device for bridging expansion joints in roadways, having an extruded mat made of elastomeric material bridging the joint, the longitudinal edges of which are parallel to the joint and are each fastened in an upwardly open groove of a retaining profile on the edge, for which purpose the Ribs are formed on the underside of the mat, which engage in the groove in a form-fitting manner and essentially fill this apart from a remaining anchoring space.
Eine derartige Vorrichtung ist durch die europäische Patentanmeldung 86 277 Bl bekanntgeworden. Die bekannte Vorrichtung umfaßt eine Matte mit extrudierbarem Pro¬ filquerschnitt. Dessen randseitige nach unten vorsprin¬ gende Rippen greifen jeweils in eine nach oben offene Nut eines Halteprofils ein, welches im Betonunterbau des Fugenrands verankert ist. Die Matte deckt nach oben das Halteprofil vollständig db und schließt mit den Seitenrändern bündig an die Fahrbahnoberfl che an. Dieser Anschluß ist jedoch der direkten Walkarbeit durch den darüberrollenden Verkehr ausgesetzt, was zu vorzeitiger Ermüdung des elastomeren Mattenmaterials und in der Folge davon zu einem Ausreißen der Matte aus der Verankerung führen kann. Hinzu kommt, daß die hinter einen seitlichen Vorsprung des Halteprofils einschnappenden Rippen funktionsbedingt die Nuten nicht vollständig ausfüllen; dies ermöglicht eine Deformation des Mattenrands unter den auftretenden Radlasten, wo¬ raus ebenfalls eine vorzeitige Ermüdung des elastomeren Materials resultiert.Such a device has become known from European patent application 86 277 B1. The known device comprises a mat with an extrudable profile cross section. Its ribs projecting downwards on the edge each engage in an upwardly open groove of a holding profile which is anchored in the concrete substructure of the joint edge. The mat covers the holding profile completely db and closes with the side edges flush with the road surface. However, this connection is exposed to direct flexing work due to the traffic rolling over it, which can lead to premature fatigue of the elastomeric mat material and, as a result, to the mat being torn out of the anchorage. In addition, the ribs which snap behind a lateral projection of the holding profile do not completely fill the grooves due to their function; this enables the edge of the mat to be deformed under the wheel loads that occur, which likewise results in premature fatigue of the elastomeric material.
Demgegenüber liegt der vorliegenden Erfindung die Auf¬ gabe zugrunde, bei einer gattungsgemäßen Vorrichtung den Randanschluß für die elasto ere Matte so auszubil¬ den, daß Hohlräume und örtliche Überdehnungen im Ver¬ bindungsbereich vermieden werden und daß trotz einfa¬ cher Herstellung eine funktionssichere und dauerhafte Verbindung zwischen Mattenrand und Fugenrand ge¬ währleistet ist. In contrast, the present invention is based on the task of designing the edge connection for the elastic mat in a generic device in such a way that cavities and local overexpansions in the connection area are avoided and that despite simple manufacture a functionally reliable and permanent connection between the edge of the mat and the edge of the joint is guaranteed.
Diese Aufgabe wird nach dem erfindungsgemäßen Vorschlag dadurch gelöst, daß der Verankerungsraum über Gußkanäle bildende Löcher oder Schlitze der Matte mit deren «Oberseite verbunden ist und daß die Rippen mittels eines die Gußkanäle und den Verankerungsraum füllenden Gußkörpers aus einem elastomeren Kunstharz mit dem Halteprofil verbunden sind.This object is achieved according to the proposal according to the invention in that the anchoring space is connected to the top side by means of holes or slits of the mat forming casting channels and that the ribs are connected to the holding profile by means of a cast body filling the casting channels and the anchoring space from an elastomeric synthetic resin.
Nach diesem Vorschlag bildet das Halteprofil einen geschlossenen Verankerungsraum, in dessen Innerem der Mattenrand verspannungsfrei aufgenommen und dauerhaft befestigt ist. Der Gußkörper bildet eine feste unlös¬ bare Verbindung zwischen dem Mattenrand und dem Halte¬ profil. Er kann in der Werkstatt oder erst vor Ort gegossen werden.According to this proposal, the holding profile forms a closed anchoring space, in the interior of which the edge of the mat is received tension-free and permanently attached. The cast body forms a firm, non-detachable connection between the mat edge and the holding profile. It can be cast in the workshop or only on site.
Da der Verankerungsbereich durch das Halteprofil gewis¬ sermaßen gekammert ist, wird eine besonders dauerhafte Verbindung geschaffen, die insbesondere unempfindlich gegenüber der durch die Radlasten ausgeübten Walkar¬ beit ist. Since the anchoring area is, as it were, chambered by the holding profile, a particularly permanent connection is created which is particularly insensitive to the walking work performed by the wheel loads.
Als geeignetes Material für den Gußkörper bietet sich Polyurethan an, dessen Härte derjenigen der elastomeren Matte ähnlich sein sollte. Beim Vergießen ist zu beach¬ ten, daß keinerlei Hohlräume im Verankerungsbereich verbleiben, ά .ft . der zwischen Halteprofil und Matte vor dem Vergießen vorhandene Verankerungsraum muß voll¬ ständig mit elastomerem Gießharz ausgefüllt werden.A suitable material for the cast body is polyurethane, the hardness of which should be similar to that of the elastomeric mat. When casting, it should be noted that no voids remain in the anchoring area, ft .ft. the anchoring space between the holding profile and the mat before casting must be completely filled with elastomeric resin.
Eine bevorzugte Ausführungsform sieht vor, daß die Schlitze durch Trennfugen zwischen getrennten Matten¬ teilen, nämlich zwischen Mittelabschnitten oder einem Mittelabschnitt und jeweils einem Randabschnitt- der Matte gebildet sind. Bei mittelsymetrischer Ausbildung der Randabschnitte ergibt sich dabei die Möglichkeit, mit zwei Extrudierformen, eine für den Mittelabschnitt und eine für die beiden Randabschπrtte, auszukommen.A preferred embodiment provides that the slots are formed by parting lines between separate mat parts, namely between central sections or a central section and in each case one edge section of the mat. If the edge sections are formed by means of symmetry, there is the possibility of using two extrusion molds, one for the middle section and one for the two edge sections.
Der Mittelabschnitt der Matte, gleichgültig ob mit den Randabschnitten verbunden oder unverbunden, ist hinsichtlich seiner Querschnittsform frei wählbar, d.h. der erfindungsgemäß vorgeschlagene Randanschluß ist nicht auf eine Kombination mit einem bestimmten Mattentyp eingeschränkt. The cross-sectional shape of the central section of the mat, regardless of whether it is connected or not connected to the edge sections, can be freely selected, ie the edge connection proposed according to the invention is not restricted to a combination with a specific type of mat.
Insbesondere bei der einteiligen Matte besteht eine zweckmäßige Ausführungsform darin, daß am Randcbschnitt ein Isolierstreifen angeformt ist.In the case of the one-piece mat in particular, an expedient embodiment consists in that an insulating strip is formed on the edge section.
Eine bevorzugte Ausführungsform sieht vor, daß das Halteprofil als C-Profil ausgebildet ist und daß die Rippen seitliche Ansätze aufweisen, welche hinter die nach innen gerichteten ProfilStege des C-Profils grei¬ fen.A preferred embodiment provides that the holding profile is designed as a C-profile and that the ribs have lateral shoulders which engage behind the inwardly directed profile webs of the C-profile.
Im folgenden wird ein Ausführungsbeispiel der Erfin¬ dung anhand der Zeichnung erläutert. Diese zeigt einen vertikalen Querschnitt durch eine Überbrückungsvorrich- tung im Bereich des Randanschlusses.An exemplary embodiment of the invention is explained below with reference to the drawing. This shows a vertical cross section through a bridging device in the area of the edge connection.
Die Zeichnung zeigt eine Überbrückungsvorrichtung am Beispiel einer Dehnfuge mit zwei Mittellamellen (1). Die Fugenmitte ist durch eine vertikale Mittellinie (2) angegeben. Sowohl auf jeder Lamelle (1) als auch auf einem L-förmigen Randprofil (3) ist jeweils ein C-förmiges Halteprofil (4) mit der Öffnung nach oben aufgeschweißt. The drawing shows a bridging device using the example of an expansion joint with two central slats (1). The middle of the joint is indicated by a vertical center line (2). A C-shaped holding profile (4) is welded with the opening facing upwards on each lamella (1) and on an L-shaped edge profile (3).
Das Randprofil (3) ist mittels seitlich daran ange¬ schweißter Platten (5) und durch Öffnungen (6) der Platten verlegter Verankerungstäbe (7) im Betonunter¬ bau des Fugenrands fest verankert. Auf der Oberseite (8) des Betonunterbaus ist eine Isolierung (9), z.B. aus einer Kunststoffolie verlegt. Dicht über der Iso¬ lierung (9) liegt ein Isolieranschluß (10), welcher an einen Randabschnitt (11) der die Fuge überbrücken¬ den elastomeren Matte (12) angeformt ist. Die elasto- mere Matte (12) z.B. aus Gummi, ist zusammengesetzt aus einem Mittelabschnitt (13) und den zwei Randab¬ schnitten (11"), von denen lediglich der linke Randab¬ schnitt (11) gezeichnet ist. Für den Mittelabschnitt (13) sind beliebige, die auftretenden Dehnungen im wesentlichen ohne Verwölben aufnehmende Querschnitts- formen denkbar. In dem gezeichneten Beispiel sind lediglich beispielhaft zwei Querschnittsformen ge¬ zeichnet, nämlich eine Ausführungsform mit Hohlräumen (14), die über offene Schlitze (15) mit der Unterseite der Matte (12) verbunden sind, und eine Ausführungsform mit abwechselnd an der Mattenoberseite und der Matten¬ unterseite vorgesehenen, im Querschnitt dreieckförmigen Einschnitten (16), wobei die Matte (12) in Art eines Faltmechanismus beweglich ist. An der Mattenunterseite angeformte Rippen (17) einer¬ seits des Randabschnitts (11), andererseits des Mit¬ telabschnitts (13) der Matte (12) greifen in das In¬ nere jeweils eines Halteprofils (4) ein. Die Rippen (17) weisen seitliche, zur Profilwand hin vorspringen¬ de Ansätze (18) auf, mit welchen sie die nach innen gerichteten Profilstege (19) des C-förmigen Halte¬ profils (4) hintergreifen. Dieses formschlüssige In¬ einandergreifen von Ansätzen (18) und ProfiIstegen (19) erleichtert das exakte Ausrichten der Mattenteile für das nachfolgende Vergießen. Der sich dabei bildende Gußkörper (20) füllt einerseits den Zwischenraum zwischen den Mattenabschnitten (11, 13), andererseits den zwischen den Ri pen (17) und der Innenwand des Halteprofils (4) verbleibenden Verankerungsraum (21) aus. Dabei entsteht eine elastomere Verbindung im Innenbereich der Halteprofile (4), welche unempfindlich ist gegen die darüber rollenden Radlasten. Lediglich außerhalb der Halteprofile (4) vorgesehene, daran an¬ schließende Hohlräume (22) dienen dem Ausgleich von Verformungen der Matte (12) quer zur Fuge. Diese Hohl¬ räume (22) haben keinen Einfluß auf die Festigkeit der Verbindung. Eine Lücke zwischen dem seitlichen Mattenrand und dem Fahrbahnbelag (23) kann ebenfalls mit elasto erem, aushärtbarem Kunstharz, beispielsweise Polyurethan, unter Ausbildung einer Dichtleiste (24) vergossen wer¬ den. Zum Erleichtern des Gießvorgangs können die auf¬ einander zugerichteten Ränder einerseits des Randab¬ schnitts (11) andererseits des Mittelabschnitts (13) der Matte (12) zur Mattenoberseite hin abgeschrägt oder ausgebuchtet sein, so daß ein Gußtrichter (25) entsteht.The edge profile (3) is firmly anchored in the concrete substructure of the joint edge by means of plates (5) welded to the side and anchoring rods (7) laid through openings (6) in the plates. On the top (8) of the concrete substructure there is insulation (9), for example made of a plastic film. An insulating connection (10) is located directly above the insulation (9) and is molded onto an edge section (11) of the elastomeric mat (12) bridging the joint. The elastomeric mat (12), for example made of rubber, is composed of a middle section (13) and the two edge sections (11 " ), of which only the left edge section (11) is drawn. For the middle section (13 Arbitrary cross-sectional shapes which absorb the strains essentially without warping are conceivable. In the example shown, only two cross-sectional shapes are shown by way of example, namely an embodiment with cavities (14) which are connected to the underside of the Mat (12) are connected, and an embodiment with incisions (16) which are triangular in cross section and are provided alternately on the mat top and the mat bottom, the mat (12) being movable in the manner of a folding mechanism. Ribs (17) formed on the underside of the mat on the one hand the edge section (11) and on the other hand the middle section (13) of the mat (12) engage in the interior of a respective holding profile (4). The ribs (17) have lateral projections (18) projecting towards the profile wall, with which they engage behind the inwardly directed profile webs (19) of the C-shaped retaining profile (4). This positive interlocking of lugs (18) and professional bars (19) facilitates the exact alignment of the mat parts for the subsequent casting. The cast body (20) that forms fills on the one hand the space between the mat sections (11, 13), on the other hand the anchoring space (21) remaining between the ri pen (17) and the inner wall of the holding profile (4). This creates an elastomeric connection in the interior of the holding profiles (4), which is insensitive to the wheel loads rolling over it. Only adjacent cavities (22) provided outside the holding profiles (4) serve to compensate for deformations of the mat (12) transverse to the joint. These cavities (22) have no influence on the strength of the connection. A gap between the side edge of the mat and the road surface (23) can also be sealed with an elastomeric, curable synthetic resin, for example polyurethane, to form a sealing strip (24). To facilitate the pouring process, the mutually facing edges of the edge section (11) on the one hand and the central section (13) of the mat (12) on the other hand can be chamfered or bulged so that a casting funnel (25) is created.
Wie bereits angedeutet kann der Zwischenraum zwischen dem Randabschnitt (11) und dem Mittelabschnitt (13) der Matte (12) entweder als durchgehender Schlitz (26) zwischen separaten Mattenabschnitten (11, 13) ausge¬ bildet sein; es können aber auch in Fugenl ngsrichtung begrenzte Schlitze (26) vorgesehen sein, die zweckmäßig in eine einteilige Matte (12) eingeschnitten werden; ebenso können anstelle der Schlitze (16) Bohrungen eingebracht werden, so daß zum Vergießen Löcher mit der in der Zeichnung dargestellten Querschnittsform entstehen. As already indicated, the space between the edge section (11) and the central section (13) of the mat (12) can either be a continuous slot (26) between separate mat sections (11, 13); but it is also possible to provide slots (26) which are limited in the direction of the joint and which are expediently cut into a one-piece mat (12); Likewise, holes can be made instead of the slots (16), so that holes with the cross-sectional shape shown in the drawing are formed for potting.
