Abstract

The invention discloses a core area strengthening type circular concrete-filled steel tube column and steel beam connecting joint structure. The core area strengthening type circular concrete-filled steel tube column and steel beam connecting joint structure comprises a circular steel pipe, a core area inner cylinder, an arc end plate and a steel beam. The core area inner cylinder is arranged in the circular steel pipe. The outer wall of the core area inner cylinder tightly attaches to the inner wall of the circular steel pipe. The arc end plate is sequentially connected with the circular steel pipe and the core area inner cylinder by a fastening piece. The inner wall of the arc end plate tightly attaches with the outer wall of the circular steel pipe. The end of the steel beam is connected with the arc end plate. The invention further discloses a construction method of the core area strengthening type circular concrete-filled steel tube column and steel beam connecting joint structure. The connecting joint structure is high in bearing capacity, reliable in mechanical capacity and simple in structure. The construction method is quick and simple, construction period can be obviouslyshortened, and excellent economic performance is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering and combined structures, in particular to a connection node structure and a construction method of a reinforced circular steel pipe concrete column and a steel beam in a core area. Background technique [0002] As a new building structure, the concrete-filled steel tube structure has been widely used in engineering practice due to its remarkable characteristics such as high strength, good seismic performance, and convenient construction. However, at present, there are not enough connection forms between circular concrete-filled steel tube columns and steel beams, and the existing forms also have problems such as complex design and difficult construction. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a connection node structure of a reinforced circular steel pipe concrete column and a steel ...
