Abstract

The invention relates to a supporting plate for bridges and ramps having roadways and/or walking areas, with longitudinal girders (1) arranged on both sides, which are connected by many hollow transverse profiles (3), the mutually facing legs (5) of which are connected positively. In order to be able to use closed transverse profiles (3) and to effect a modular construction of the supporting plate, the transverse profiles (3) are according to the invention connected via a weld (weld seam) to the longitudinal girders, which is arranged between the longitudinal girders and a side leg of the transverse profiles. The weld seams of all transverse profiles in this case face one end of the supporting plate. <IMAGE>

Description

Die Erfindung betrifft eine Tragplatte für Fahrbahnen und/oder Gehflächen aufweisende Brücken und Rampen mit zu beiden Seiten angeordneten Längsträgern, die durch eine Vielzahl einander paralleler, rechteckiger oder quadratischer, hohler Querprofile verbunden sind, deren einander zugekehrte senkrechte bzw. im wesentlichen senkrechte Schenkel in formschlüssiger Verbindung stehen.The invention relates to a support plate for lanes and / or walkways bridges and 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 vertical or substantially vertical legs in a form-fitting Connect.

Bei den bekannten Tragplatten dieser Art 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 Verschraubungen nur unten offene Querprofile benutzt werden können, sind besonders profilierte Querprofile erforderlich, da sie längsverlaufende Profilabschnitte benötigen, die die seitlichen, senkrechten Schenkel der Querprofile bilden müssen.In the known support plates of this type, the cross profiles which are open at the bottom are screwed at their ends to the longitudinal members and are provided laterally with longitudinal, projecting strips which engage in a corresponding side groove in the adjacent profile. In addition to the fact that only cross sections that are open at the bottom can be used with these support plates because of the screw connections, particularly profiled cross sections are required, since they require longitudinal profile sections that must form the lateral, vertical legs of the cross sections.

Der Erfindung liegt die Aufgabe zugrunde, Tragplatten der eingangs erwähnten Art so auszubilden, dass steifere, geschlossene Querprofile benutzt werden können, dennoch aber ein einfacher, baukastenartiger Zusammenbau der Tragplatte vollzogen werden kann.The invention has for its object to design support plates of the type mentioned so that stiffer, closed cross sections can be used, but still 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 ( Schweissnaht ) mit den Längsträgern verbunden, die zumindest im wesentlichen zwischen den Längsträgern und einem Seitenschenkel der Querträger angeordnet ist. Zweckmässigerweise sind dabei die Schweissnähte von zumindest mehreren aufeinander folgenden Querprofilen einem Ende der Längsträger zugekehrt. Zudem 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 erstreckt 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 cross profiles, but preferably all cross profiles arranged between the end parts of the support plate, are connected to the side members via a weld (weld seam), which is arranged at least essentially between the side members and a side leg of the cross members. The weld seams of at least several successive transverse profiles expediently face one end of the side members. In addition, the weld seams are dimensioned such that they extend at least over the greatest part of their length in the area of the side legs, 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 also is provided in the area of the upper and lower walls of the cross sections.

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 eines Querprofils, sondern über die Schweissverbindung auch die ihr zugekehrte Seite des benachbarten Querprofils.Such a simple, one-sided fastening 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 a cross profile, but also the side of the adjacent cross profile facing it via the weld connection.

Besonders günstig ist auch die Herstellung der erfindungsgemässen Tragplatten. So ist es möglich, beim Zusammenbau der Tragplatte z.B. senkrecht oder steil anstehende Längsträger nacheinander mit den Querprofilen zu versehen und nach Anbringung von Distanzkörpern auf dem schon montierten Querprofil das 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 das anzuschweissende Querprofil bereits von vornherein mit einem Vorsprung ausgestattet ist, auf den dann das folgende Querprofil aufgesetzt werden kann, wenn die Schweissung vollzogen ist. Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist.The production of the support plates according to the invention is also particularly favorable. It is possible, for example, to assemble the support plate vertically or to provide steeply standing longitudinal members with the cross profiles one after the other and, after attaching spacers to the already assembled cross profile, to mount the following cross profile by placing them on the spacers, whereby after mounting a cross profile the respective side leg located above 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 when installing the cross profiles (due to the steep or vertical side members and the support from 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. 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 über die gesamte Länge dieser Arbeitsfläche erstrecken.Bei einer Profilbreite von z.B. 14o mm und einer Profilhöhe von etwa 8o mm der Seitenschenkel 5 sind die Querprofile 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-shaped 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, the top wall 4 of which is used for driving or walking, which can also be provided with coverings to improve slip resistance. The cross profiles 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 over the entire length of this work surface. 14o mm and a profile height of about 8o mm of the side legs 5, the transverse profiles 3 are arranged so that their mutual distance is about 5 mm.

Die Seitenschenkel 5 der Querprofile 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 profiles 3 are provided slightly above half the height of the side legs 5 with bores 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 thrust and rotation when the ramp is loaded.

Wichtig ist die Herstellungsmethode 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 Montagestellung bequem oben; weitere Schweissnähte bzw. Verbindungsstellen werden im Regelfalle 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 production method of the support plate according to the invention is important. In the parallel position, the two longitudinal members 1 are arranged so as to 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 in the assembly position mentioned above; As a rule, no further welds or joints are drawn. When this welded connection has been made, the cross section 3 thus fastened is again fitted with the parts 7, 8 and the following cross section 3 can then 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 ).Total seen those side legs 5 are attached to the weld 9, which are facing 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, which may be arranged there).
