Round steel pipe concrete column joint for beam column connection and method for manufacturing the same

Abstract

The invention discloses a kind to use in beam column the connection round steel pipe coagulation earth pyramid pitch point and its the manufacture method, it mainly included the round steel pipe coagulation earth pyramid and the steel girder which connected with this column, the round steel pipe coagulation earth pyramid and filled in in this round steel pipe including the round steel pipe the concrete, in carried with steel pipe coagulation earth pyramid connection steel girder Liang is equipped with an end board, this steel pipe coagulation earth pyramid with stated between the end board to be equipped with the belt rib level the steel plate, level the steel plate solidified on the round steel pipe, carried the board, level the steel plate as well as the round steel pipe through as soon as passed through core excels in the bold fastening in together. The invention cost inexpensive, mechanics performance good, design succinct convenient, the construction difficulty is small, also can avoid the scene welding, improves the connection quality and the construction benefit.

Description

technical field [0001] The invention mainly relates to a building structure component, in particular to a node used for the structural connection of circular steel pipe concrete columns and steel beams. Background technique [0002] Concrete filled steel pipe has the advantages of high strength, good ductility, fatigue resistance, impact resistance, and easy construction. Therefore, this technology has been successfully applied to high-rise, long-span, heavy-load, earthquake-resistant and explosion-proof projects. The circular concrete-filled steel tube column has the advantages of strong hoop effect and large diameter (width)-thickness ratio under compression, so it is very popular. However, the traditional joint type of the circular steel tube concrete column steel beam structure system is relatively complicated, which has become a bottleneck restricting its wide application. [0003] In the prior art, the connection joints between the circular steel pipe column and the s...
