Reinforced steel structure bridge prefabricated assembly

Abstract

The invention relates to a reinforced steel structure bridge prefabricated assembly which comprises a column body, a base, a supporting block, fixing blocks, fixing mechanisms, locking mechanisms, supporting plates, limiting mechanisms and guiding mechanisms. The base is arranged on the outer side face of the column body in an up-down sliding fit mode, and the supporting block of a trapezoidal structure is installed at the upper end of the column body; the fixing blocks are evenly arranged on the outer side faces of the supporting block and the column body, the fixing mechanisms are arranged between the fixing blocks and the column body and between the fixing blocks and the supporting block, the supporting plates are arranged between the fixing blocks and the upper ends of the supporting block through locking mechanisms, the limiting mechanisms are arranged at the upper ends of the middles of the supporting plates, and the guiding mechanisms are arranged at the upper ends of the left sides and the right sides of the supporting plates. The problems that in the prior art, in the steel structure bridge building process, a common transport vehicle cannot transport bridge supporting columns conveniently, and the transport efficiency of the bridge supporting columns is reduced, the assembling steps of all the assemblies are tedious, and the assembling efficiency of the bridge supporting column is reduced are solved.

Description

technical field [0001] The invention relates to the field of bridge components, in particular to a reinforced steel structure bridge prefabricated component. Background technique [0002] Steel bridge, the bridge whose main load-bearing structure adopts steel, that is, steel structure bridge, steel bridge. Prefabricated steel bridges have been 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 only need to be transported by ordinary medium-sized trucks. In special cases, it can be built entirely by manpower; however, as With the development of the times, more and more steel structure bridges have appeared in cities. However, the following problems usually exist in the construction process of existing stee...

AI Technical Summary

Problems solved by technology

[0003] 1. The bridge support columns of existing steel structure bridges are usually large in size, which makes it inconvenient for general transport vehicles to transport them, thereby reducing the efficiency of transporting bridge support columns;

[0004] 2. The assembly steps between the various components of the bridge support column of the existing steel structure bridge are relatively cumbersome, and a large number of welding methods with low assembly efficiency are used, thereby reducing the efficiency of assembling the bridge support column
