Description

一种钢管混凝土柱与钢梁的装配式连接节点A prefabricated connection node between a steel tube concrete column and a steel beam

技术领域technical field

With the development of economy and society, the demand for rapid construction and large-scale production of multi-storey high-rise buildings is increasing. The traditional rectangular concrete-filled steel tube column and steel beam joints are mainly welded on site. The construction speed is slow and the construction energy consumption is high, which is not conducive to the realization of assembly construction and large-scale production. The transmission of the joint is usually realized by the bending of the column wall plate, and the inner filling concrete cannot be fully utilized to improve the bearing capacity of the joint; at the same time, the seismic performance of the joint is greatly affected by the quality of the on-site welding. How to realize the full assembly between rectangular concrete filled steel tube columns and steel beams in high-rise buildings on the basis of making full use of the inner filling concrete to ensure the joint bearing capacity is a problem that needs to be solved urgently in engineering practice.
