S-shaped steel structure bridge

Abstract

The invention discloses an S-shaped steel structure bridge comprising: a S-shaped shock absorbing steel, a handholding beam bar, a first through beam, a second through beam, a third through beam, a fourth through beam, a pedestal welded panel, a support side plate, a force-release sloping plate and a section bar basket; the handholding beam bar is paralleled to the pedestal welded panel; the firstthrough beam, the second through beam, the third through beam and the fourth through beam are arranged between the handholding beam bar and the pedestal welded panel; the first through beam, the second through beam, the third through beam and the fourth through beam vertically penetrate the S-shaped steel structure bridge; the S-shaped steel structure bridge is vertically welded between the handholding beam bar and the pedestal welded panel. The S-shaped shock-absorbing steel of the invention is provided with a shock-absorbing steel welded block, a front shock-absorbing steel plate, a rubbershock-absorbing pad and a rear shock-absorbing steel plate. The S-shaped steel structure bridge realizes both the force and load relief, and the cushioning and shock absorption stability effect. The bridge with the multi-functional steel structure is safer.

Description

technical field [0001] The invention is an S-shaped steel structure bridge, which belongs to the field of steel structure bridge equipment. Background technique [0002] Steel bridge, the bridge whose main load-bearing structure adopts steel, that is, steel structure bridge, steel bridge. Prefabricated steel bridges are widely used all over the world. The original fabricated steel bridge was designed by British engineer Donald Bailey in 1938 at the beginning of World War II. The main design concept is to assemble the least types of unit components into a prefabricated steel bridge capable of carrying various loads and different spans, and it only needs to be transported by ordinary medium-sized trucks. In special cases, it can be built entirely by manpower. [0003] The prior art discloses an S-shaped steel structure bridge with application number CN201120129499.8, which includes a main girder and piers, and the main girder includes at least one section of "S"-shaped struc...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an S-shaped steel structure bridge to solve the problem that the S-shaped steel structure bridge has no shock absorption effect and cannot buffer shock absorption to protect the stability of the bridge steel structure under an earthquake state
