Description

Die Erfindung betrifft eine Tragplatte für eine Fahrbahn 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 Schenkel in Verbindung stehen, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a support plate for bridges and ramps having a carriageway, with longitudinal beams arranged on both sides, which are connected by a multiplicity of parallel, rectangular or square hollow cross sections, the mutually facing legs of which are connected, according to the preamble of patent claim 1.

Bei bekannten Tragplatten für Brücken und Rampen der obigen Art sind die einander zugekehrten Schenkel benachbarter Querprofile derart über die gesamte Länge der Querprofile hinweg profiliert, dass ein Vorsprung eines Schenkels in eine Vertiefung des anderen Schenkels eingreifen kann ( EP-A-0 223 147 ).In known support plates for bridges and ramps of the above type, the mutually facing legs of adjacent cross profiles are profiled over the entire length of the cross profiles in such a way that a projection of one leg can engage in a recess in the other leg (EP-A-0 223 147).

Ausgehend von der Erkenntnis, dass eine gute Schenkelverbindung der Querprofile eine günstige Lastverteilung auf mehrere Querprofile zur Folge hat und demgemäss auch zu einer grösseren Belastbarkeit führt, liegt der Erfindung die Aufgabe zugrunde, die eingangs erwähnten Tragplatten so auszubilden, dass die Schenkelverbindung mit geringem technischen Aufwand zustandekommen kann und darüber hinaus die Möglichkeit gegeben ist, beim Zusammenbau der Tragplatte die Querprofile einfach zusammenzusetzen, ohne dazu zusätzliche Verbindungsmittel in Anspruch nehmen zu müssen.Based on the knowledge that a good leg connection of the cross profiles results in a favorable load distribution over several cross profiles and accordingly also leads to greater resilience, the object of the invention is to design the support plates mentioned in the introduction in such a way that the leg connection with little technical effort can come about and, moreover, there is the possibility of simply assembling the cross profiles when assembling the support plate without having to use additional connecting means.

Zur Lösung dieser Aufgabe sind erfindungsgemäss die Merkmale nach dem Kennzeichnungsteil des Patentanspruchs 1 vorgesehen.To achieve this object, the features according to the characterizing part of claim 1 are provided according to the invention.

Dabei können die Winkelstücke als schmale Abschnitte von Winkeleisen ausgeführt sein, die über die Länge der Querprofile verteilt angeordnet werden. Diese Winkelstücke werden vor dem Zusammenbau der Tragplatte bzw. der Rampe befestigt.The angle pieces can be designed as narrow sections of angle iron, which are arranged distributed over the length of the cross sections. These elbows are attached before the support plate or ramp is assembled.

Die Erfindung schlägt weiterhin wirksame Mittel vor, um die Rutschsicherheit der Fahrbahn zu erhöhen., eine Massnahme, die besonders bei schräg anstehenden Rampen von Bedeutung ist.Aus diesem Grunde werden zumindest auf einige Querprofile U-Profile aufgesetzt, deren Steg profiliert ist und deren Abwinkelungen zwischen benachbarte Querprofile eingeführt sind. Die Stege dieser U-Profile können Noppen, Ausstanzungen, Beläge od. dgl. aufweisen, um die Griffigkeit zu verbessern.The invention also proposes effective means to increase the slip resistance of the road, a measure that is particularly important in the case of inclined ramps. For this reason, at least some cross profiles are placed on U profiles, the web of which is profiled and the angles thereof are inserted between adjacent cross sections. The webs of these U-profiles can have knobs, punched-out areas, coverings or the like in order to improve the grip.

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.

Es zeigen :

  • Fig. 1 einen Teilquerschnitt durch eine Tragplatte für eine stationäre oder verfahrbare, schräge oder horizontale Rampe,
  • Fig. 2 einen Teilschnitt nach der Linie II-II von Fig. 1,
  • Fig. 3 ein U-Profil zur Erhöhung der Rutschsicherheit im Querschnitt und
  • Fig. 4 das Profil gemäss Fig. 3 in der Seitenansicht.
Show it :
  • Fig. 1 shows a partial cross section through a support plate for a stationary or movable, oblique or horizontal ramp,
  • 2 shows a partial section along the line II-II of FIG. 1,
  • Fig. 3 is a U-profile to increase the slip resistance in cross section and
  • Fig. 4 shows the profile of FIG. 3 in side view.

Die Rampe ist zu beiden Seiten mit einem Längsprofil 1 versehen, dessen Steg mit 2 und dessen waagerechter Schenkel mit 3 bezeichnet sind.The ramp is provided on both sides with a longitudinal profile 1, the web of which is designated 2 and the horizontal leg of which is 3.

Zwischen den Stegen 2 der beiden Längsprofile 1 sind dicht bei dicht Querprofile 4 als Hohlprofile mit rechteckigem Querschnitt vorgesehen. Ihre obere Wandung 5 bildet die Wirkfläche, also die Fahrbahn der Rampe. Die Querprofile 4 erstrecken sich über die gesamte Breite der Fahrbahn und somit von einem zum anderen Längsträger 1, an denen sie durch Schweissen od.dgl. befestigt sind.Between the webs 2 of the two longitudinal profiles 1 cross profiles 4 are provided as hollow profiles with a rectangular cross section. Its upper wall 5 forms the active surface, that is the roadway of the ramp. The cross sections 4 extend over the entire width of the road and thus from one to the other side member 1, on which they are welded or the like. are attached.

Damit sich die Querprofile 4 gegenseitig abstützen können, wenn sie von oben belastet werden, sind die Querprofile 4 an einem Schenkelstück 6 mit mehreren Winkelstücken 7 versehen, die als asymmetrische Winkeleisenabschnitte ausgeführt sind, von denen ein Schenkelstück 8 mit einem Schenkelstück 6 der Querprofile 4 fest z.B. durch Schweissen verbunden ist. Das andere Schenkelstück 9 steht hingegen seitlich als Vorsprung ab und dient als Auflage für das benachbarte Querprofil 4. Die Winkelstücke 7 sind gleichmässig über die Rampenbreite verteilt mit einem Abstand von etwa 4o-8o cm, jedoch richtet sich der Abstand natürlich nach den geforderten Belastungen.So that the cross profiles 4 can support each other when they are loaded from above, the cross profiles 4 are provided on a leg piece 6 with a plurality of angle pieces 7, which are designed as asymmetrical angle iron sections, of which one leg piece 8 with a leg piece 6 of the cross profiles 4 fixed is connected by welding, for example. The other leg piece 9, however, protrudes laterally as a projection and serves as a support for the adjacent cross section 4. The angle pieces 7 are evenly distributed over the ramp width with a distance of about 4o-8o cm, but of course the distance depends on the required loads.

Aus Fig. 2 ist erkennbar, dass die einzelenen Querprofile 4 geringfügig gegeneinander versetzt sind, um eine erhöhte Griffigkeit durch Stufung zu erzielen. Dementsprechend sind auch die Winkelstücke 7 angeorodnet. Fig. 2 lässt ferner erkennen, dass die Wandstärke der Schenkelstücke 8 den gegenseitigen Abstand der Querprofile 4 bestimmt.From Fig. 2 it can be seen that the individual cross sections 4 are slightly offset from each other in order to achieve increased grip by gradation. Accordingly, the elbows 7 are arranged. FIG. 2 also shows that the wall thickness of the leg pieces 8 determines the mutual spacing of the cross profiles 4.

Damit eröffnet sich die Möglichkeit, auf die Querprofile 4 U-Profile 11 aufzusetzen, deren Steg 1o satt auf der Wandung 5 aufliegt und aussen mit kleinen Vorsprüngen 12 versehen ist, die die Rutschsicherheit verbessern. Die Abwinkelungen 13 der U-Profile 11 erstrecken sich in den Raum zwischen benachbarte Querprofile 4 und können dort eingeklemmt sein. Zur besseren Halterung entspricht die Länge der U-Profile 11 dem gegenseitigen Abstand der Winkelstücke 7. Zudem können die Abwinkelungen 13 auch so bemessen sein, dass sie verklemmt sind.This opens up the possibility of placing 4 U-profiles 11 on the transverse profiles, the web 10 of which rests snugly on the wall 5 and is provided on the outside with small projections 12 which improve the slip resistance. The bends 13 of the U-profiles 11 extend into the space between adjacent cross profiles 4 and can be clamped there. For better mounting, the length of the U-profiles 11 corresponds to the mutual distance between the angle pieces 7. In addition, the bends 13 can also be dimensioned such that they are jammed.

Vor dem Zusammenbau der Rampe werden die Querprofile 4 mit den Winkelstücken 7 versehen. Zum Zusammenbau sind also lediglich die Verbindungen zu den Längsträgern 1 herzustellen.Before assembling the ramp, the cross sections 4 are provided with the elbows 7. For assembly, only the connections to the side members 1 are to be made.
