Abstract

The invention relates to a modular bridge (BL) formed by at least two inter-coupled short bridges (BK), wherein a short bridge (BK) contains the following components: an inner section (BI), two upward pivoting ramp sections (BR), two lower chords (U) firmly connected to the inner section (BI) and the ramp sections (BR) of the bridge, and lower chords (UB) which can be displaced in the direction of the bridge span width in relation to the firmly connected lower chords (U). The short bridges (BK) are coupled together on the tips (RS) of the upwardly pivoted ramp sections (BR) and on the displaced lower chords (UB).

Description

Modular Bridge {MODULAR BRIDGE}

The object of the present invention is to produce a module bridge which can be assembled from existing short bridges as soon as possible.

The present invention relates in particular to a modular bridge that can be used flexibly, wherein the module bridge consists of at least two short bridges which can be interconnected.

The problem is solved by the application of claim 1. A useful embodiment of the invention is an application of the claims.

Modular bridges (hereinafter referred to as long bridges) according to the invention are made by interconnecting two or more short bridges. In this case, one short bridge has the following parts:

Internal fragment of one bridge

-Bridge plate fragment that can be flipped over two tops

Lower flanges rigidly connected to bridge inner and bridge plate segments

Long bridges are made up of individual short bridges by flipping the top of the lower bridge flange, which can be pushed in the bridge width direction against the firmly connected lower bridge, and by interconnecting by pushing the lower flanges of the two short bridges. do.

Useful embodiments of the invention are described in detail in the figures.

The short bridges BK, each represented by a load-bearing structure, have two bridge plate segments BR and one bridge inner segment BI, respectively (Figs. 1 and 5, 7). The plate fragment BR is connected to the end of the inner fragment BI through the link portion G. The inner piece BI and the plate piece BR each have two track pedestals in this embodiment, wherein each track pedestal includes one runway F and a side wall S. FIG. The runway plate simultaneously serves as a flex support. Each track pedestal of the inner piece BI is interconnected via a transverse pedestal Q. The bridge fragments BI, BR have a lower flange U firmly connected to the side wall S and are inverted in the shape of a U in the example shown in FIG. 7 (FIG. 7) in four U-shaped rigid lower flanges U. FIG. There is one movable lower flange (UB) each, which can be pushed in the bridge width direction and has a corresponding connection point for each connection point of the rigid lower flange (U). By closing this coupling (coupling is equally indicated by K in FIGS. 1 to 4), the rigid lower flange U of each bridge cross section is interconnected with the lower flange UB, which can be pushed as a joining plate, The pushable lower flange UB is connected according to its strength. In the exemplary embodiment shown here, the coupling is configured in the form of a trough connection using bolts BZ (FIG. 7).

The pushable lower flanges UB, shown as separate parts in the embodiments of FIGS. 1 to 4, can be installed in several pieces independently of one another. This is especially true when the plate segment BK and the inner segment BI are of different lengths or when two or more short bridges are connected by long bridges.

Opening the lower flange coupling allows the following (Figs. 2 and 3).

1. The plate fragment BR of the short bridge BK can be flipped upward.

2. The movable lower flange UB can be pushed and the plate fragment BR to the side where the upper end is flipped over.

Solid bottom of individual bridge segments (BI, RR) with plate fragment (BR) turned up by means of connecting point (KV) in pushable lower flange (UB) and pushed lower flange (UB) The flange (U) can be reconnected, so the short bridge (BK) of this configuration is a load-bearing structure.

By selecting the total length of the movable lower flange UB as required, the lower flange UB and the plate fragment BR with the two short bridges BK having this configuration in accordance with FIGS. Can be connected to plate end (RS). By doing this, a long bridge BL having a length twice as shown in FIG. 4 can be made.

The present invention is not limited to the long bridge consisting of two short bridges shown in FIGS. 4 and 6. Rather, according to the present invention, long bridges can be made by connecting short bridges in arbitrary numbers. In this case, the two plates lying inside the short bridge are flipped upwards. The length and number of pushable lower flanges can be adapted to the situation.
