Abstract

The invention discloses a connection joint structure for a circular concrete filled steel tubular column and a reinforced concrete beam. The connection joint structure comprises a circular steel tube,a joint adapting part and a reinforced concrete beam. A vertical square steel tube on the outer side wall of the joint adapting part is in sleeve joint with the circular steel tube. The upper end andthe lower end of the vertical square steel tube are respectively equipped with an upper end cover and a lower end cover. Concrete or mortar is poured between the vertical square steel tube and the circular steel tube. The side surface of the vertical square steel tube is equipped with end plates. Multiple double-head bolts respectively and horizontally penetrate through two sides of the circularsteel tube and the vertical square steel tube and stretch out of the end plates. Two sides at the end part of the reinforced concrete beam are equipped with steel plates. The multiple double-head bolts horizontally penetrate through the reinforced concrete beam and steel plates. The steel plates and the end plates are connected in a welding manner. The invention also discloses the construction method thereof for the connection joint structure for the circular concrete filled steel tubular column and the reinforced concrete beam. The connection joint structure is high in carrying capability andsimple in construction. The construction method is quick and simple. The construction period can be evidently shortened. The connection joint structure is highly cost-effective.

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 circular steel pipe concrete column and a reinforced concrete beam. 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. The circular steel pipe has a higher bearing capacity due to its stronger restraint on the internal concrete than the square steel pipe. However, at present, it is difficult to connect circular concrete-filled steel pipe columns and reinforced concrete beams, and the connection forms are not rich enough. The previous joint design is relatively complicated, and on-site construction is difficult. Contents of the invention [0003] Aiming at the problems exis...
