Definitions

  • the invention relates to a collapsible bridge according to the preamble of claim 1.
  • a collapsible bridge which consists of several interconnectable bridge elements.
  • the bridge elements each contain a carriageway slab, lower chords and struts.
  • the bridge elements are designed either as central elements with a horizontally running lane or as ramp elements with an inclined lane. Ramp elements cannot be used as central elements, so that a relatively large number of parts must be carried when transporting the bridge.
  • DE-OS 38 14 502 discloses a bridge of the same type that can be dismantled from individual bridge elements that can be coupled together.
  • the bridge elements consist of a truss consisting of carriageway slabs, lower chords and diagonal struts. Since the lower chords and the diagonal struts are telescopic in their length or can be attached to certain coupling points, the height of the components can be adjusted.
  • the object of the invention is to improve such a bridge that it becomes lighter and simpler in construction.
  • the bridge according to the invention is lighter and simpler in construction than the one just described, since there are no telescopic parts (the double-walled design must be) are more necessary.
  • the height and inclination of the bridge modules are freely selectable.
  • the articulation of the diagonal elements at the ends of the lower chords allows for an easier construction of the lower chords than with an articulation in the middle.
  • the version with the very short diagonal elements (shorter than half the lower chords) further reduces the overall weight.
  • the shortness of the lower chords compared to the roadway automatically results in a higher bridge height (an arch) with the greater length.
  • the bridge module B here consists of a roadway element F , two lower chords U and four diagonal struts D.
  • the diagonal struts D and the lower flange U can be sunk into the track element F for space-saving transport.
  • the roadway element F here, as can be seen below, has a U-shaped cross section, which leaves space in the middle for a front-end beam or a front-end navel or a laying beam.
  • the lower flange U is shorter than the roadway element F , as a result of which the lower flange U can be completely "sunk" into the roadway element F.
  • the relatively short diagonal struts D can also be completely sunk in the roadway element F in the transport state or in the short bridge his.
  • the different fastening options for the diagonal elements D and the lower flange U in the carriageway element F can also be seen .
  • different fastening options 1, 2, 3, 0 for the diagonals D and for the lower flange U are shown at each end of the roadway element F.
  • the attachment points are at different locations.
  • the upper end of the diagonal D is here (for example in rails) in the carriageway element F. When folded, the upper end is at point 0 ( 0 ' ). When F is raised , U and D unfold automatically. The attachment point 1 is removed from the attachment point 0 by the length of a diagonal D.
  • FIG. 2 shows three versions of bridges according to the invention, each of which is assembled from 1, 2 or 3 of the bridge modules B shown in FIG. 1.
  • 1 shows a short bridge at the top, the length of which corresponds to a bridge module B and the height H1 of which corresponds to the height of the roadway element F.
  • the diagonals D and the lower chords U are, as shown in FIG. 1 above, sunk in the road element F.
  • Fig. 2 shows in the middle a bridge of medium span coupled together from two bridge modules B.
  • the lower chords U are no longer arranged at the outer fastening points 1 , but at the further inner fastening points 2 and 2 ' .
  • the other end of the lower chord is connected to the lower chord of the other bridge module.
  • the top Ends of the middle diagonal struts D shift from the points 0 or 0 ' to 3 or 3' during the unfolding.
  • the bridge has a greater height H2 and thus a load capacity adapted to the greater length.
  • 2 shows a long bridge composed of three bridge modules B with the correspondingly larger height H3 .
  • the lower flange U is articulated at the attachment point 3 , which is farther from the end than the attachment point 2 .
  • the left diagonal D has no function in the lane F.
  • the right diagonal of the left bridge module B is articulated at the fastening point 1 'of the road element F. The same applies to the right bridge module B in mirror image.
  • the middle bridge module B is coupled between the two bridge modules B mentioned .
  • the lower chords U of the three bridge modules are directly connected to each other, as are the carriageway elements, so that the desired higher curve results.
  • the diagonal struts D of the middle bridge module are fastened in the fastening points 3, 3 'of the roadway element F of the middle bridge module B.
