Definitions

  • the invention relates to a bridge that can be assembled from individual bridge sections, in which each bridge section has the following parts which are detachably connected to one another: two truss girder arrangements - one on each bridge side - each with an upper chord, a lower chord and diagonals and at least one cross member (plus a cross member for the entire bridge).
  • Such a bridge is known from DE-OS 22 50 013. It is suitable for heavy vehicles, especially tanks, as a route over obstacles, e.g. B. rivers, gorges, etc. to serve.
  • the known bridge has heavy lattice girder arrangements with a triangular cross section, between which cross girders are fastened to the inner bottom chord profile, which in turn are connected in pairs by longitudinal girders. A large number of boards are placed on the side members to cover the roadway.
  • the disadvantage of this bridge is that the truss girder arrangements require a considerable amount of transport space.
  • the cross members connected by longitudinal members also require a corresponding transport space.
  • the many individual carriageway boards also require a lot of assembly work.
  • Another disadvantage is that the connection points arranged outside of the vertical center plane through the truss arrangements for the cross members are correspondingly rigid must be trained.
  • the invention has for its object to provide a relocatable bridge that can be transported in parts to planes or helicopters to the desired location, possibly dropped by parachutes and assembled there by little personnel without a separate device in the free stem.
  • the truss girder arrangements can be folded into one plane for the transport state, that the cross girders in the fully assembled bridge for direct or indirect support on the lower chord of the truss girder arrangement over the lower chord or - in the case of a truss girder arrangement with several lower chord profiles - protrudes laterally beyond the respective inner lower flange profile, and that on each side of the bridge there is a positive connection between the upper flange and cross member in two different planes, each running parallel to the longitudinal direction of the bridge.
  • Each bridge section and thus the entire main support system of the bridge has only a few differently designed components. These can be so easily formed by their dimensions and a material with a low specific mass that they can be z. B. carried from the drop point to the site and can be assembled there by hand.
  • the foldability of the truss girder arrangements significantly reduces the transport space required. In spite of this, no great assembly effort is required for the assembly, because the framework support arrangements only need to be unfolded.
  • the design of the cross beams and their support allows a uniform loading of the lower flange profiles of each truss arrangement, so that the connection can be made simple and easy to assemble.
  • the cross beams can be loaded compactly and only need a small transport space.
  • lattice girder arrangements In order to bring the lattice girder arrangements into a stable position immediately at the start of assembly, in a further development of the invention they consist of two lattice girder walls which are articulated in the area of the upper chord and which can be brought apart with their own lower chords by unfolding.
  • a cross bar to one of the truss walls of each truss arrangement, which cross bar is provided for resting on both lower chords of the truss arrangement.
  • the interlocking connection between the top flange and the crossbeams is preferably realized by means of posts hinged to the top flange, which can be pivoted into the plane of the truss walls for transport and pivoted out of them for assembly.
  • the planes of the posts can be at an angle to one another in the fully assembled state and can also be arranged symmetrically to the center plane of the truss arrangement.
  • the lattice girder arrangement can also consist of only a single lattice girder wall, which is supported on the crossbeam via pivoted supports or posts.
  • the support at the same time forms part of the positive connection between the upper chord and the cross member.
  • the cross members are provided with receptacles for roadway plates according to a development of the invention
  • Cross beams arranged pins are fixed in their position.
  • An aluminum alloy is provided as the material so that the individual parts can be carried by people.
  • fiber-reinforced plastics can also be used as construction material.
  • the bridge according to the invention can be used both as a fixed bridge for resting on the banks of obstacles and, when placed on floating bodies, can serve as a ferry or floating bridge. Additional ramps can be arranged.
  • the floating bridge B consists of individual, together connecting bridge sections A of z. B. 2.75 m in length, each supported on an inflatable boat D.
  • a special end field E is arranged on the outermost bridge sections, which is used to link a ramp plate R which rests on the bank of a water W. For handling the ramp plate R , it is connected to the top chord of the bridge truss at its ascending end via a length-adjustable cable pull S.
  • Each bridge section A has on each side a lattice girder arrangement 10 with two lattice girder walls (hereinafter also referred to only briefly as “wall” or “walls”) 11, 12.
  • Each truss girder wall 11, 12 has a tubular upper chord profile (hereinafter also referred to as “upper chord”) 13 and a tubular lower chord profile (hereinafter also referred to as “lower chord”) 14, which are supported by vertical supports 15 and diagonal struts 16 are connected.
  • top chords 13 of the two truss walls are held together by a buckle arrangement 17. Within this buckle arrangement, the upper straps 13 are pivoted about their own axis. On the lower chords 14 of the outer walls 11 cross bars 18 are hinged to bolts 19.
  • the bridge sections A also have two cross members 23 and two roadway plates 24. At the end of the bridge, a further cross member 23 is additionally required for completion.
  • the cantilevered end of a crossbeam 23 is placed on each of two adjacent crossbeams 18, pins 25 located on the underside of the crossbeams 23 engaging in corresponding recesses in the crossbeams 18.
  • the pins 25 grant and secure a perfect position of the parts to each other.
  • the crossbeams 18 serve for uniform introduction of the load on the crossbeams 23 into the lower chords 14.
  • the crossbeams 23 are located at the joint and in the middle of each bridge field or section A.
  • the roadway plates 24 are inserted.
  • the roadway plates 24 each lie with their transverse edges on a support plate 27 on the underside of the cross member 23.
  • pins 28 on the support plate 27 and corresponding recesses in the roadway plates 24 on the one hand the position of the roadway plates 24 and, at the same time, a large transverse stability of the individual bridge section A and the whole bridge.
  • the posts 21 are pivoted out of the wall 11 and the posts 22 out of the wall 12 in order to produce a fixed, form-fitting connection between the truss support assemblies 10 and the cross members 23 for the transmission of compressive and tensile forces.
  • the roadway has Schrammborde 31, which is on the top of the Roadway plates 24 are articulated.
  • the embodiment according to FIG. 5 differs from the embodiment described above essentially in that the posts 21, 22 which can be pivoted out of the truss walls 11, 12 produce a connection - in relation to the central plane of the truss assembly 10 - that is central.
  • the cross members 23 rest directly on the lower chords 14 of the walls 11, 12.
  • pins 32 are provided on the lower chords 14.
  • the posts 21, 22 articulated on the upper chords 13 for the positive connection between the framework support arrangement 10 and the cross members 23 remain in this embodiment within the planes of the walls 11, 12.
  • the truss arrangement merely consists of a truss wall 33, on the lower flange 14 of which the cross member 23 rests.
  • the form-fitting connection between the truss wall 33 and the cross beams 23 is established by means of posts 35 which can be pivoted within the plane of the wall 33 and posts or supports 36 which can be pivoted from this plane, the posts 36 being fastened to the projecting lateral ends of the support arms 23.
  • the truss girder walls 33 are carried by hand to the bridge point and placed there flat. After placing the cross member 23, the completely assembled bridge wall is erected and secured with the help of the posts 36 connected to the cross member 23.
