Connecting method and connecting structure for box-type steel pipe column and shear wall end post

Abstract

The invention discloses a connecting method and a connecting structure for a box-type steel pipe column and a shear wall end post. The connecting method comprises the following steps: the box-type steel pipe column is provided; a plurality of shear resisting connecting bonds are fixedly connected onto one side of the box-type steel pipe column; a rebar structure for bonding a shear wall end post enables the vertical rebar part of the shear wall end post to be arranged in the shear resisting connecting bonds in a penetrating manner; form erecting is performed and the shear wall end post is poured. A row of shear resisting connecting bonds is fixed at a side part of the box-type steel pipe column, the vertical rebar part of the shear wall end post is arranged into the shear resisting connecting bonds in a penetrating manner, and a plurality of composition steel bars are arranged in the shear wall end post in a matching manner, so the shear wall end post is tightly buckled onto the shear resisting connecting bonds, and meanwhile, a reliable connection effect of shear resisting and pulling resisting between shear resisting connecting bonds and the shear wall end post can be played. The connecting strength between the box-type steel pipe column and the shear wall end post can be enhanced, the entire anti-seismic property of the structure is enhanced, and compared with a like method, the method provided by the invention has the advantages that the on-site construction difficulty is low, the construction quality is high, the working period is shortened and the cost is reduced.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a connection method and a connection structure suitable for a box-shaped steel pipe column and a shear wall end column in a cast-in-place steel-concrete composite structure. Background technique [0002] The seismic performance of shear wall structures plays a vital role in the safety and reliability of high-rise buildings, but the disadvantage of concrete shear walls is that the ductility of concrete walls is poor. Although the use of box-shaped steel pipe columns has improved the performance of the structure, how to effectively connect them with the concrete shear walls and make the two coordinate work has become a difficult problem. There are many connection nodes between the box-shaped steel pipe column and the end column of the concrete shear wall, and the construction is difficult. The connection between traditional box-shaped steel columns and shear wall end column...
