In view of the above, the utility model provides an assembled highway steel bridge end post which is simple and convenient to process and manufacture, has high erection and assembly speed, can reduce nonlinear deformation of the structure, and effectively overcomes the defects of the existing assembled highway steel bridge.
In order to solve the problems in the prior art, the utility model adopts the following technical scheme: an assembled highway steel bridge terminal post which is characterized in that: the end posts consist of web members and joint plates welded on two sides of the web members; the web members are double channel steel which are arranged back to back in parallel, and the two channel steel are connected into a whole through a plurality of connecting pieces.
Further, a cross beam backing plate is welded to the inner side of the longitudinal edge of the joint plate.
Further, the joint plate is an L-shaped steel block, pin holes are uniformly distributed on the longitudinal edges of the joint plate, and U-shaped grooves are formed on the transverse edges of the joint plate.
Further, the beam backing plate is welded perpendicularly to the longitudinal edge surface of the joint plate.
Further, the joint plate is arranged between the two channel steel through the transverse edge and is connected with the back of the channel steel.
Further, the connecting piece is a connecting plate and a supporting plate.
Further, the supporting plate is a rectangular steel plate with a hole in the middle.
Further, the connection plate and the stay plate are welded between the two channel steels.
Compared with the prior art, the utility model has the advantages that:
1) The end post has the same structure, adopts a symmetrical design, can realize indifferent installation, is convenient and quick to install, and saves time;
2) The utility model has simple structure and convenient factory manufacture.
3) The end column structure and the truss unit are connected through multiple pins, so that nonlinear deformation is small.
