Safe and convenient connection structure for precast reinforced concrete beam and steel pipe column

Abstract

The invention discloses a safe and convenient connection structure for a precast reinforced concrete beam and a steel pipe column and belongs to the field of building structures. The safe and convenient structure comprises the precast reinforced concrete beam and the steel pipe column, and a positioning plate, an upper partition and a lower partition are arranged at the positions of nodes of the steel pipe column; upper node steel plates and lower node steel plates are respectively in lap joint at two ends of an upper horizontal steel bar and a lower horizontal steel bar of the precast reinforced concrete beam, and positioning connecting plates are arranged at ends of the upper node steel plate; the strength of the upper and lower node steel plates is identical to total strength, replaced at the corresponding position, of longitudinal steel bars; positioning connecting plates at two ends of the precast reinforced concrete beam are connecting with the positioning plates of the steel pipe column, the upper and lower node steel plates are respectively correspondingly connected with the upper and lower partitions of the steel pipe columns, and the precast reinforced concrete beam and the steel pipe column are molded in casting in situ and integrally connected. The safe and convenient connection structure is concise, the upper and lower node steel plates are in lap joint with the longitudinal steel bars at the set positions, requirements on equal strength are met, mechanics characteristics of the beam are met, and the beam and the nodes are guaranteed in safety and reliability.

Description

technical field [0001] The invention relates to a safe and convenient connection structure between a prefabricated reinforced concrete beam and a steel pipe column, which belongs to the field of building structures. Background technique [0002] In the prior art, the reinforced concrete beams connected with steel pipe columns are basically cast-in-place reinforced concrete beams. The operation is: interspersing steel bars at the joints or constructing reinforced concrete ring beams. Prefabricated buildings require high prefabrication rate, fast assembly speed and convenient installation. Therefore, with the development of prefabricated buildings, it is urgent to solve the problem of safe and convenient connection structure of prefabricated reinforced concrete beams, reinforced concrete composite beams and steel pipe columns. . Contents of the invention [0003] The purpose of the present invention is to provide a safe and convenient connection structure between prefabrica...
