Quick assembling and disassembling steel-structure pedestrian overpass

Abstract

The invention provides a quick assembling and disassembling steel-structure pedestrian overpass which comprises piers, a bridge arranged on the piers and provided with a bridge deck, stairs arranged at two ends of the bridge, and guardrails arranged on two sides of the bridge and the stairs. The quick assembling and disassembling steel-structure pedestrian overpass is characterized in that the bridge is composed of a plurality of I-beams with through holes and connecting components; the connecting components include end plates, clamping plates and connecting plates, the end plates are arranged at the head and tail ends of each I-beam and provided with through holes, the clamping plates are arranged in grooves of the I-beams and provided with through holes, and each connecting plate provided with through holes is arranged between every two adjacent clamping plates, and bolts and nuts are arranged in the through holes. The pedestrian overpass can be assembled or disassembled quickly and conveniently, so that time for building or demolishing is shortened greatly, and road traffic pressure is relieved; furthermore, the disassembled pedestrian overpass is reusable, thus materials and cost are saved greatly. In addition, due to an assembled structure, assembly parts can be produced and transported in batches, and the pedestrian overpass is beneficial to large-scale and intensive production, transportation and assembly.

Description

[0001] technical field [0002] The invention relates to a pedestrian bridge, in particular to a steel structure pedestrian bridge that can be quickly disassembled, and belongs to the technical field of bridge building design and manufacture. Background technique [0003] Pedestrian bridge is an indispensable building structure in urban construction, and it can solve the traffic safety problems existing in the mixed traffic of people and vehicles. However, since the existing pedestrian bridges are mostly steel-concrete structures, when they are constructed in cities with a large number of people and a large traffic flow, it will take a long time and occupy limited road resources, which will adversely affect urban road traffic and people's travel. At the same time, when the urban planning changes and the permanent bridge needs to be dismantled, it is not only time-consuming and labor-intensive, but also can no longer be used once dismantled, resulting in a waste of raw materi...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing pedestrian bridge uses steel-concrete structure, which takes up road resources during construction or dismantling, which is time-consuming and labor-intensive, and cannot be reused, or because of the steel structure, it has heavy weight, large amount of welding construction, and inconvenient disassembly and assembly, etc. Problem, the present invention provides a steel structure pedestrian bridge that can be quickly disassembled
