Definitions
- the invention relates to a collapsible bridge, i.e. a transportable bridge for mobile use, according to the preamble of claim 1.
- CH 336 183 discloses a pyramidal support structure that can also be used for a bridge.
- Several connected pyramidal support structures form a truss with a triangular cross-section, with lower chords running through the two lower corners at the same height, and an upper chord running through the upper corner.
- DE 40 00 987 A1 discloses a bridge-laying method for a composite girder bridge with a concrete carriageway on a steel substructure.
- the individual precast concrete elements of the carriageway which were previously positioned on the bridge abutment in the axis of the bridge, are successively moved into their installation positions via the steel substructure and then seamlessly connected with in-situ concrete.
- the bridge according to the invention comprises track girders which are designed as truss girders with a triangular cross section, with lower chords running through the two lower corners lying at the same height, and an upper chord running through the upper corner, and roadway plates which form the roadway of the bridge.
- the road slabs are placed on the top chord.
- the track supports are reinforced by the roadway plates that are laid on them and connected in a force-locking and shear-resistant manner.
- the track carriers can be designed very easily, since the top flange cross section that is actually required is only created together with the shear-rigidly connected roadway plate, which absorbs the longitudinal forces.
- the minimized cross-section of the unreinforced track carrier results in favorable torque conditions for the laying of the bridge, which enable an easy laying device with low counterweights.
- the bridge consists of only a few individual parts and can therefore be installed very quickly using mechanized installation devices.
- a plurality of hinge lines are present on the individual carriageway slab sections in the longitudinal direction of the bridge, by means of which the carriageway slab sections can be folded together.
- the disassembled bridge can thus be stowed optimally in volume and thus air-transportable.
- the weight-optimized design of the bridge and the foldable deck sections allow air transport in all common transport aircraft.
- Typical spans of the bridge according to the invention are in the range of 25-30 m.
- the internal static connection of a track carrier is preferably realized with optimal weight through non-detachable connections (e.g. welding, riveting).
- the bridge can therefore be installed with a minimum number of connecting elements. There are no loose elements that could easily get lost in the rain, ice and snow and in the dark.
- Such a framework can be optimally designed to be lightweight and rigid.
- CFRP fiber-reinforced plastic
- FIG. 1 shows a bridge according to the invention in cross section (section transverse to the longitudinal direction of the bridge);
- Figure 2 shows a detail for the frictional and shear-resistant connection of the top chord and roadway plate in two cuts parallel and transverse to the longitudinal direction of the bridge.
- 3 shows a detail of a further embodiment of the non-positive and shear-resistant connection of the upper chord and roadway plate in two cuts parallel and transverse to the longitudinal direction of the bridge;
- Fig. 5 is a sketch of the method of laying the bridge according to the invention in two snapshots (side view).
- Fig. 1 shows a bridge according to the invention in cross section. It comprises two track supports 3 with a triangular cross section, which are composed of one or more track support sections in the longitudinal direction of the bridge.
- the track girders each represent a truss girder (diagonal bars 1), a lower flange 4 being provided in each of the two lower corners, and the upper flange 5 being present in the upper corner of the cross section.
- the two track supports are connected by transverse ribs 2, which ensure the parallelism of the two track supports 3.
- the top chord is dimensioned so that it is able to absorb the tensile forces from the laying process of the bridge.
- the upper belts are designed in such a way that they enable a non-positive and shear-resistant connection to the carriageway plate 6, which is placed on the upper belts 5 of the track carriers 3.
- the shear-resistant and non-positive connection between the deck plate 6 and the upper flange 5 can be achieved by means of push rods 9 that transmit tension and pressure.
- 2 shows two push rods 9 arranged in pairs and symmetrically to a horizontal central axis.
- Reference numeral 91 denotes a connecting element of the push rod.
- the two push rods 9 should be arranged at an angle as acute as possible to the road surface. The longitudinal force transmission between the roadway slabs themselves takes place by contacting the end face slab cross-sectional areas (pressurized bending side).
- the shear-resistant and non-positive connection between the road slab 6 and the upper flange 5 can be realized by a special flange element 8 (FIG. 3).
- Upper flange 5 and roadway plate 6 are clamped together by means of a clamping device 81, 82, 83.
- an intermediate piece 84 which is three-dimensionally structured on one side (e.g. having a toothing or corrugation) and is pressed with its toothed side against a second, plasticizing and shear-absorbing intermediate piece 85. By pressing the toothed side onto the second intermediate piece 85, the latter is plastically deformed.
- the surface structure of the structured intermediate piece 84 is impressed on the second intermediate piece, so that a form fit between the two intermediate pieces 84, 85 is achieved in this area.
- materials for the plastically deformable intermediate piece 85 preferably iron materials, steels, sheets with good plastic deformability can be used.
- the connection can be released again by loosening the tensioning device 81, 82, 83.
- the once deformed intermediate piece 85 can be replaced by a new one for the next construction of the bridge, so that optimum shear strength is always achieved.
- FIG. 4 shows a section of the carriageway slab 6 in the transport position.
- the roadway plates can be folded together on the hinge lines 10, so that dimensions suitable for air transport are achieved.
- FIG. 5 a laying method adapted to the construction of the bridge according to the invention is described.
- the first image in FIG. 5 shows the snapshot, after which two track plate sections 61, 62 have already been coupled together and connected to the track supports 3.
- a third carriageway slab section 63 is being pushed over the track supports 3 using the guide elements 7 supported on rollers.
- the guide system 7 can be designed to be light and multifunctional, for lifting, lowering and guiding.
- the jacking can be done manually or by means of manually operated jacking devices, eg winches.
- the second picture in FIG. 5 shows the completely built bridge after all four road slab sections 61-64 of the bridge have been laid and successively connected to the track supports 3 in a non-positive and shear-resistant manner.
- the installation procedure is as follows:
- the two track supports 4 of the bridge are cantilevered. As soon as the two track carriers 3 are deposited on both banks, the first
- Road slab section 61 opened and placed on this side end DE of the bridge on the top chords 5 of the two track supports 3.
- Guide elements 7 (in FIG. 5 are arranged on the carriageway plate section 63, which is being laid at the time shown) are provided on the carriageway slab section, by means of which the carriageway slab section 61 is then pushed over the track supports 5 to the other end JE of the bridge.
- the carriageway slab section 61 is non-positively and shear-rigidly connected to the track supports 3 so that the carriageway slabs can be integrated into the longitudinal force flow.
- next carriageway plate section 62 is then displaced in the same way over the track supports 3 and coupled to the previously laid carriageway plate section 61, and is also connected to the track supports 3 in a non-positive and shear-resistant manner.
- This procedure ensures in particular that the road surface plate is optimally adapted to the bending line of the track supports.
- the described laying of the carriageway slab sections is continued until the end of the bridge on this side is reached.
- the roller-based transport system can also be used, for example, to replace a defective section of a carriageway on a bridge that has already been laid.
- the shear-resistant connections to the track supports are released manually and the road slabs can be slid on and off in accordance with the required sequence.
- the described method is optimally adapted to the construction of the bridge according to the invention and enables the bridge to be built very quickly.
- the number of bridge sections used depends on the required span and is at least 1.
- the bridge shown in FIG. 5 consists, for example, of 4 bridge sections.
