Problems solved by technology

At present, the arrangement of shear studs mainly adopts the uniform distribution type, and the force of the shear studs is relatively uniform, but it also causes the concrete bridge deck to be divided into blocks and more wet joints, which causes construction inconvenience and increases the construction period

Embodiment

[0040] Example: The Yuxi River Super Bridge Project of Chaohu-Wuwei Section of North Yanjiang Expressway in Anhui Province:

[0041] 1. Project overview

[0042] The starting point of this project is connected to the end of the Maanshan-Chaohu section of the North Yanjiang Expressway, and a Chaohu hub interchange is set up to connect to Hechaowu Expressway; the end point is a T-shaped hub interchange to connect to the planned Tongling Yangtze River Highway and Railway Bridge highway connection at Taqiao.

[0043] This project includes the engineering design, construction, construction and monitoring of the Yuxi River Main Bridge, the Zhui Sanhe Bridge and the Yuxi River Super Bridge. Continuous box girder bridge and other bridge types. The project design concept is advanced, the bridge structure is complex, the construction scale is large, and the construction difficulty is high, representing the advanced level of domestic expressway bridge construction.

[0044] Among them,...

Abstract

The invention discloses a shear connector of a steel-concrete combined beam bridge, comprising a clustered shear connector and an open-end plate shear connector. The invention has the following beneficial effects: the construction is simple, only holes are required to be processed in a steel plate, without needing any special machining; the welding is convenient, skirting weld seam welding is adopted along two sides of the steel plate, without needing any special welding equipment; a perforated plate is arranged along a longitudinal bridge direction of a wing plate, and can play a role of a reinforced plate; and the shear connector has the advantages of high anti-fatigue performance, high rigidity, small slippage, improved force performance of the structure and simplified construction.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to a shear connector of a steel-concrete composite beam bridge. Background technique [0002] Prestressed concrete girder bridge is a bridge structure widely used in highway bridge construction in my country. Large and medium bridges with a span of 50 to 100 meters mostly use prestressed concrete beams. Compared with developed countries, the development of my country's steel bridge technology is extremely unbalanced. On the one hand, it is a high-level application of super-large bridges and large bridges; on the other hand, it is a low-level application of small and medium bridges with a small total amount. [0003] Due to unbalanced technological development, there are many quality problems in general concrete bridges in my country, and there are technical bottlenecks such as hole plugging, inaccurate control of tension and prestress, and insufficient grouting in the prestressed p...
