Integral assembled steel bridge deck for temporary bridge to improve bridge durability

Abstract

The invention discloses an integral assembled steel bridge deck for a temporary bridge to improve bridge durability. The integral assembled steel bridge deck for the temporary bridge to improve the bridge durability comprises a bridge surface splicing plate, four fixed columns are fixedly connected to the side wall, close to a splicing joint, of the bridge surface splicing plate, the four fixed columns are symmetrically distributed on the upper side and the lower side of the bridge surface splicing plate, and a plurality of connecting plates are arranged on the side wall of the bridge surfacesplicing plate. Limiting holes are formed in the side wall of the connecting plates, limiting blocks are matched with the fixed columns, a pressing device is arranged on the side wall of the bridge surface splicing plate, and a knocking device is arranged on the lower side wall of the bridge surface splicing plate. According to the integral assembled steel bridge deck for the temporary bridge to improve the bridge durability, the bridge surface is conveniently spliced and convenient to disassemble and install, when external factors cause resonance, the vibration frequency of the bridge surfacecan be changed by knocking, the situation that a bridge is enabled to be damaged due to long time resonance is avoided, and the durability of the bridge is increased.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an integrally assembled steel bridge deck for a temporary bridge that improves the durability of the bridge. Background technique [0002] Looking at the field of infrastructure construction at home and abroad, or in front of emergency rescue and disaster relief, the first thing we need is a smooth material transportation line. Due to the constraints of the environment, geography and other conditions, a large part of the lines need to use temporary bridge structures, especially during the construction of permanent bridges across waters, and before emergency rescue and disaster relief. Temporary bridge structures to meet traffic needs. [0003] Temporary bridges are diversified and multi-form. According to the disaster situation, the terrain of overhaul construction, driving conditions, and safety conditions, temporary bridges that meet the requirements of safe driving, drainage ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing temporary bridge overlap is cumbersome, and installation and disassembly are inconvenient. At the same time, the vibration frequency of the bridge deck cannot be changed during resonance, which increases the safety hazard of the bridge.
