Face, the upper surface of steel corrugated plating are that rivet welding is connect with plane steel plate, are connected by bolt with the fashioned iron of stringer below steel corrugated plating
It connects, the wave crest of steel corrugated plating and the direction of trough and the length direction of stringer are vertical.
The above-mentioned steel construction Simple bridge having compared with high bearing capacity, the bridge pier have 2-3 at the both ends of bridge respectively, 2-
3 bridge piers are transversely arranged, corresponding to have 2-3 stringer to be erected on bridge pier in parallel, laterally set up floorings on adjacent stringer.
The above-mentioned steel construction Simple bridge having compared with high bearing capacity, the bridge pier have on the length direction of bridge it is multiple,
Stringer is set up on adjacent bridge pier respectively, is laid with floorings on stringer.
The above-mentioned steel construction Simple bridge having compared with high bearing capacity is filled out in the ripple gap of the steel corrugated plating of the floorings
Water-filling cement mortar or foamed material.
The beneficial effects of the utility model are:
The bridge pier, stringer, floorings of the utility model can take dismountable connection, and fast and easy dismounting is convenient for
In emergency circumstances carry out fast construction；Floorings use the composite structure of steel corrugated plating and plane wave, can play steel corrugated plating
Advantage light-weight, non-deformability is strong enables bridge floor will not deformation occurs when heavy weight vehicle passes through.
The utility model is simple and reasonable, light-weight, non-deformability is strong, be quickly and expediently installed, the construction time is short, can
It is built with quick assembling, heavier vehicle can be carried, be unlikely to deform damage, be particularly conducive to taking precautions against natural calamities, mitigation, meeting an urgent need, robbing
It plays a significant role when dangerous.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of Fig. 1；
Fig. 3 is the structural schematic diagram of floorings.
It is marked in figure as follows: bridge pier 1, stringer 2, floorings 3, steel corrugated plating 4, plane steel plate 5, bolt 6.
Specific embodiment
The utility model is made of bridge pier 1, stringer 2, floorings 3.
It is shown in figure, bridge pier 1 is steel column structure, and bridge pier 1 is located at the both ends of bridge, and bridge pier 1 vertically squeezes into ground.Bridge pier 1
Steel column structure can use fashioned iron or steel plate welding production, directly squeeze into ground at the construction field (site), or be put into foundation pit and fill out
It buries, be poured.Bridge pier 1 can also use reinforced concrete structure, can transport site operation after factory makes, if when
Between allow, can also pour at the scene.It, can also be using the bridge pier of damage bridge, to adapt to emergency in rescue and relief work.
It is shown in figure, stringer 2 is formed steel construction, is made by I-steel, channel steel, angle steel, or be welded as case using steel plate
Body, it is ensured that have enough intensity.The both ends of stringer 2 are erected on the bridge pier 1 at both ends, and 2 bottom surface of stringer passes through with 1 top surface of bridge pier
Reservation member is by being bolted, or to be welded to connect.
It is shown in figure, floorings 3 are laid on stringer 2, are walked for vehicle and pedestrian.Floorings 3 are by 4 He of steel corrugated plating
Plane steel plate 5 forms, and steel corrugated plating 4 is connected to below plane steel plate 5, the wave crest of steel corrugated plating 4 and the direction of trough and vertical
