Abstract

The invention relates to a supporting plate for bridges or ramps having a roadway and/or walking surfaces, with longitudinal supports (1) arranged on both sides, which are connected by a large number of mutually parallel, rectangular or square hollow transverse profiles (3), the mutually facing legs (5) of which in turn are positively connected. In order to be able to use closed transverse profiles (3) and to implement a modular assembly of the supporting plate, the mutually facing side legs (5) are according to the invention provided with recesses (6) which correspond to one another and in which distance members (7, 8), which are inserted loosely between the transverse profiles (3), engage in a practically play-free manner with projections arranged on both sides. <IMAGE>

Description

Die Erfindung betrifft eine Tragplatte für eine Fahrbahn und/oder Gehflächen aufweisende Brücken oder Rampen mit zu beiden Seiten angeordneten Längsträgern, die durch eine Vielzahl einander paralleler, rechteckiger oder quadratischer hohler Querprofile verbunden sind, deren einander zugekehrte Schenkel ihrerseits in formschlüssiger Verbindung stehen.The invention relates to a support plate for a roadway and / or walkways having bridges or ramps with longitudinal beams arranged on both sides, which are connected by a plurality of mutually parallel, rectangular or square hollow cross sections, the mutually facing legs of which in turn are in a positive connection.

Bei bekannten Tragplatten dieser Art (EP-A-0 223 147) sind die unten offenen Querprofile an ihren Enden mit den Längsträgern verschraubt und seitlich mit längsverlaufenden, vorspringenden Leisten versehen, die in eine entsprechende Seitennute des benachbarten Profils eingreifen. Abgesehen davon, daß bei diesen Tragplatten wegen der Verschraubung nur unten offene Profile benutzt werden können, sind besonders profilierte Querprofile erforderlich, da sie längsverlaufende Profilabschnitte benötigen, die die seitlichen, senkrechten Schenkel der Querprofile bilden müssen.In known support plates of this type (EP-A-0 223 147), the cross profiles open at the bottom are screwed at their ends to the side members and laterally provided with longitudinal, projecting strips which engage in a corresponding side groove of the adjacent profile. In addition to the fact that only profiles open at the bottom can be used with these support plates because of the screw connection, particularly profiled cross profiles are required since they require longitudinal profile sections which must form the lateral, vertical legs of the cross profiles.

Bei einer anderen bekannten Tragplatte der eingangs genannten Art (EP-A-0 583 684) sind dagegen die Querprofile mit den Längsträgern verschweißt und untereinander über Zwischenglieder formschlüssig miteinander verbunden. Bei dieser Tragplatte entfällt die Notwendigkeit, besonders profilierte Querprofile zu verwenden, und es können auch steifere, geschlossene Querprofile benutzt werden.In another known support plate of the type mentioned at the outset (EP-A-0 583 684), on the other hand, the cross profiles are welded to the side members and positively connected to one another via intermediate members. This support plate eliminates the need to use specially profiled cross profiles, and stiffer, closed cross profiles can also be used.

Der Erfindung liegt die Aufgabe zugrunde, Tragplatten der eingangs erwähnten Art so zu verbessern, daß ein einfacher, baukastenartiger Zusammenbau der Tragplatte vollzogen werden kann.The invention has for its object to improve support plates of the type mentioned so that a simple, modular assembly of the support plate can be carried out.

Zur Lösung dieser Aufgabe sind erfindungsgemäß zumindest mehrere Querprofile, vorzugsweise jedoch alle zwischen den Endteilen der Tragplatte angeordneten Querprofile über eine Schweißung mit den Längsträgern verbunden, die zumindest im wesentlichen zwischen den Längsträgern und den Seitenschenkeln der Querprofile angeordnet ist, wobei die Schweißnähte von zumindest mehreren aufeinanderfolgenden Querprofilen einem Ende der Längsträger zugekehrt sind. Zweckmäßigerweise sind die Schweißnähte so bemessen, daß sie sich zumindest über den größten Teil ihrer Länge im Bereich der Seitenschenkel erstrecken, insb. wird die Schweißnaht jedoch so ausgelegt und angeordnet, daß sie sich praktisch über die Höhe des zugehörigen Seitenschenkels und somit nicht auch noch im Bereich der oben und unten gelegenen Wandungen der Querprofile vorgesehen wird.To achieve this object, according to the invention, at least several transverse profiles, but preferably all the transverse profiles arranged between the end parts of the support plate, are connected to the longitudinal members by means of a weld which is at least essentially arranged between the longitudinal members and the side legs of the transverse profiles, the weld seams being carried out by at least several successive ones Cross profiles are facing one end of the side members. The weld seams are expediently dimensioned such that they extend over at least most of their length in the region of the side legs, but in particular the weld seam is designed and arranged in such a way that it practically extends over the height of the associated side leg and therefore not even in Area of the top and bottom walls of the cross sections is provided.

Eine derartige einfache, einseitige Befestigung der Querprofile an den Längsträgern ist deshalb möglich, weil der benachbarte, nicht angeschweißte Seitenschenkel des folgenden Querprofils formschlüssig mit dem folgenden Querprofil verbunden ist. Die an einer Seite des Querprofils vorgesehene Schweißung fixiert also nicht nur eine Seite des Querprofils, sondern über die Schweißverbindung auch die ihr zugekehrte Seite des benachbarten Querprofils.Such a simple, one-sided attachment of the cross profiles to the side members is possible because the adjacent, non-welded side leg of the following cross profile is positively connected to the following cross profile. The weld provided on one side of the cross profile thus fixes not only one side of the cross profile, but also the side of the adjacent cross profile facing it via the welded connection.

Die Herstellung der erfindungsgemäßen Tragplatte ist besonders günstig. So ist es möglich, beim Zusammenbau der Tragplatte z.B. senkrecht oder steil anstehende Längstrbäger nacheinander mit den Querprofilen zu versehen und nach Anbringung von Distanzkörpern auf dem schon montierten Querprofil des folgende Querprofil durch Aufsetzen auf die Distanzkörper zu montieren, wobei dann nach Montage eines Querprofils der jeweils oben liegende Seitenschenkel durch eine Schweissnaht mit dem zugehörigen Längsträger verbunden wird. Angesichts des Formschlusses durch die Distanzkörper ist nämlich eine Verankerung an den Längsträgern lediglich durch eine gut anzubringende Schweissnaht möglich. Es wird also jeweils nur der Seitenschenkel der Querprofile verschweisst und verankert, der bei der Montage der Querprofile oben angeordnet ist (infolge der steilen oder senkrechten Längsträger und der Unterstützung durch die eingelegten Distanzkörper). Ein sinngemässer Zusammenbau erfolgt, wenn des anzuschweissende Querprofil bereits von vornherein mit einem Vorsprung ausgestattet ist, auf den dann das folgende Querprofil aufgesetzt werden kann, wenn die Schweissung vollzogen ist.The production of the support plate according to the invention is particularly cheap. So it is possible to assemble the support plate, for example, vertically or to provide steeply positioned longitudinal beams with the cross profiles one after the other and after attaching spacers to the already mounted cross profile of the following cross profile by placing them on the spacers, whereby after mounting a cross profile the respective upper side leg is connected to the associated side member by a weld seam . In view of the form fit by the spacers, anchoring to the side members is only possible by means of a weld seam that is easy to attach. So only the side leg of the cross profiles is welded and anchored, which is arranged at the top during assembly of the cross profiles (due to the steep or vertical side members and the support provided by the inserted spacers). An analogous assembly takes place if the cross profile to be welded is already equipped with a projection from the outset, on which the following cross profile can then be placed when the welding is completed.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist.Further details of the invention will be explained with reference to the drawing, in which an embodiment of the invention is shown.

Die Rampe ist zu beiden Seiten mit je einem Längsträger 1 in Form eines U-Eisens versehen, dessen in der Gebrauchslage der Rampe senkrechter Steg mit 2 bezeichnet ist. Zwischen den Stegen 2 der beiden Längsträger 1 sind als geschlossene Hohlprofile mit rechteckigem Querschnitt ausgeführte Querprofile 3 angeordnet; deren oben gelegene Wandung 4 die zum Befahren oder Begehen dienende Fläche bildet, welche auch mit Belägen zur Verbesserung der Rutschsicherheit versehen sein kann. Die Querprofile 3 erstrecken sich somit über die gesamte Breite der Rampenarbeitsfläche und sind auch in einer solchen Vielzahl vorgesehen, dass sie sich auch übar die gesamte Länge dieser Arbeitsfläche erstrecken. Bei einer Profilbreita von z.8. 140 mm und einer Profilhbhe von etwa 80 mm der Seitenschenkel 5 sind die Querprofils 3 so angeordnet, dass ihr gegenseitiger Abstand etwa 5 mm beträgt.The ramp is provided on both sides with a longitudinal beam 1 in the form of a U-iron, the vertical web of which is designated by 2 in the position of use of the ramp. Between the webs 2 of the two longitudinal members 1 are arranged as closed hollow profiles with a rectangular cross section transverse profiles 3; whose upper wall 4 forms the surface used for driving or walking, which can also be provided with coverings to improve slip resistance. The cross sections 3 thus extend over the entire width of the ramp work surface and are also provided in such a large number that they also extend the entire length of this work surface. With a profile width of z.8. 140 mm and a profile height of about 80 mm of the side legs 5, the cross profile 3 are arranged so that their mutual distance is about 5 mm.

Die Seitenschenkel 5 der Querprofils 3 sind etwas oberhalb der halben Höhe der Seitenschenkel 5 mit Bohrungen 6 versehen, die gleichmässig über die Länge der Querprofile 3 verteilt sind. Diese Bohrungen 6 werden von zylindrischen fluchtenden Stummeln 7 praktisch spielfrei durchsetzt, die sich zu beiden Seiten von runden Scheiben 8 befinden, die die eigentlichen Distanzkörper für die Querprofile 3 bilden und angesichts des oben genannten Bemessungsbeispiels eine Breite von etwa 5 mm aufweisen.The side legs 5 of the cross profile 3 are provided slightly above half the height of the side legs 5 with holes 6 which are evenly distributed over the length of the cross profiles 3. These holes 6 are penetrated by cylindrical aligned stubs 7 practically without play, which are located on both sides of round disks 8, which form the actual spacers for the transverse profiles 3 and have a width of about 5 mm in view of the design example mentioned above.

Die Scheiben 8 mit den Stummeln 7 halten die Querprofile 3 auf Abstand und verbinden sie formschlüssig und bei einer Belastung der Rampe schub- und verdrehungsfest.The disks 8 with the stubs 7 keep the cross sections 3 at a distance and connect them in a form-fitting manner and are resistant to shear and rotation when the ramp is loaded.

Wichtig ist die Herstallungsmethode der erfindungsgemässen Tragplatte. Die beiden Längsträger 1 werden in Parallelstellung steil anstehend oder senkrecht angeordnet zunächst mit dem Querprofil 3 verbunden, das an der Tragplatte unten liegt, was durch Anschweissen der Enden am Steg 2 erfolgt. Dieses am weitesten unten gelegene Querprofil 3 wird dann mit den Löchern 6 entsprechenden Teilen gemäss Fig. 4 versehen, worauf das folgende Querprofil 3 aufgesetzt und durch die Teile 7, 8 in seiner genauen Lage gehalten und zentriert wird. Alsdann wird der oben liegende Seitenschenkel 5 mit dem Steg 2 durch eine Schweissnaht 9 verbunden, die sich im wesentlichen über die Länge der Seitenschenkel 5 erstreckt. Diese Bereiche liegen bei der oben erwähnten Montageztellung bequem oben; weitere Schweissnähte bzw. Verbindungsstellen werden im Ragelfalle nicht gezogen. Wenn diese Schweissverbindung hergestellt ist, wird das so befestigte Querprofil 3 wiederum mit den Teilen 7,8 bestückt, und alsdann kann das folgende Querprofil 3 montiert, bestückt und angeschweisst werden.The manufacturing method of the support plate according to the invention is important. In the parallel position, the two longitudinal beams 1 are positioned so that they stand up steeply or vertically, first connected to the transverse profile 3, which lies at the bottom of the support plate, which is achieved by welding the ends to the web 2 he follows. This cross-section 3 located at the bottom is then provided with the holes 6 corresponding parts according to FIG. 4, whereupon the following cross section 3 is placed and held and centered in its exact position by the parts 7, 8. Then the upper side leg 5 is connected to the web 2 by a weld 9, which extends essentially over the length of the side legs 5. These areas are comfortably at the top of the assembly position mentioned above; no further welds or joints are drawn in the rag trap. When this welded connection is made, the cross section 3 thus fastened is again fitted with the parts 7, 8, and then the following cross section 3 can be assembled, fitted and welded on.

Insg, gesehen sind also diejenigen Seitenschenkel 5 mit der Schweissnaht 9 befestigt, die einem Ende der Längsträger 1 bzw. der Tragplatte zugekehrt sind. Dies trifft im Regelfalle für alle Querprofile 3 zu (abgesehen von den am Ende der Tragplatte ggfs. vorgesehen geänderten Befestigungsarten und die dort ggfs, angeordneten Übergangsteile wie Auffahrtbleche )Seen as a whole, those side legs 5 are fastened to the weld seam 9 which face one end of the side members 1 or the support plate. This generally applies to all cross sections 3 (apart from the different types of fastening provided at the end of the support plate and the transition parts such as access panels, if any).
