Abstract

The invention discloses a connection node structure for a rectangular steel pipe concrete column and a reinforced concrete beam, and the structure comprises a rectangular steel pipe, an end plate, fixed connecting parts, and the reinforced concrete beam. The end plate is fixed on an outer side wall of the rectangular steel pipe through a split bolt. Two opposite sides of an end part of the reinforced concrete beam are respectively provided with the fixed connecting parts, and the fixed connecting parts are connected with the end plate. The structure provided by the invention is large in bearing capacity, is reliable in bearing performance, and is simple. The invention also discloses a construction method for the structure, and the method is quick, convenient and simple, can remarkably shorten the construction cycle, and is good in economic performance.

Description

technical field [0001] The invention relates to the technical field of construction engineering and composite structures, in particular to a connection node structure and a construction method of a square 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. However, at present, the connection between the square concrete-filled steel tube column and the reinforced concrete beam is relatively difficult, and the connection forms are not rich enough. The previous joint design is relatively complicated, and the on-site construction is difficult. 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 between a...
