A high-performance prefabricated steel-concrete composite girder deck assembly seam member

Abstract

The invention discloses a high-performance prefabricated steel-concrete composite girder bridge deck slab assembling joint member and relates to the field of highway bridges. The high-performance prefabricated steel-concrete composite girder bridge deck slab assembling joint member comprises bridge deck slabs and a steel pipe, wherein each bridge deck slab consists of connecting steel plates and asteel reinforcement structural net; and the first steel plates and the second steel plates are connected and fixed together through the steel reinforcement structural nets. According to the high-performance prefabricated steel-concrete composite girder bridge deck slab assembling joint member, by clamping rectangular toothed plates arranged on the first steel plates and the second steel plates inthe two groups of bridge deck slabs in a staggered and matched manner, the two groups of bridge deck slabs are effectively and rapidly aligned, and deviation between the two groups of bridge deck slabs is prevented. According to the high-performance prefabricated steel-concrete composite girder bridge deck slab assembling joint member, as steel reinforcement welding ends are arranged in the two groups of connected bridge deck slabs in a staggered manner, the steel pipes penetrate through through-holes formed by the staggered steel reinforcement welding ends arranged in the two groups of connected bridge deck slabs, and the steel reinforcement welding ends are welded and fixed to the external walls of the steel pipes, the tensile effect between the two groups of bridge deck slabs is effectively improved, and the structural stability is improved.

Description

technical field [0001] The invention relates to the field of highway bridges, in particular to a high-performance prefabricated steel-concrete composite girder deck assembly seam member. Background technique [0002] During the bridge construction process, each girder deck is hoisted into place step by step, and the girder decks are connected through reserved wet joints. The wet joints are weak parts in the transverse bridge direction. The wet joints in the prior art Most of the jointing process adopts the welding and fixing of the steel bars reserved on the edges of the adjacent two girder deck decks, and then performs wet joints. However, this process requires high positioning accuracy of the beam body, and the positioning is cumbersome. The fatigue problem of steel bars is prominent, which affects the engineering process. In addition, after the installation is in place, it is necessary to use external measurement tools to measure the distance between adjacent panels and e...
