Fully assembled column joints connected by double steel plate bolts and its construction method and calculation method

Abstract

A double-steel plate bolt connection fully assembled column node disclosed by the invention includes an assembled integral column, and double-layer connecting steel plates are arranged on the four side walls of the assembled integral column; the assembled integral column includes an upper prefabricated column, a middle The filling layer and the precast column in the lower section, the center of the bottom end of the precast column in the upper section is a protruding tenon, and the surface of the bottom end of the precast column in the upper section is wrapped with a pre-embedded steel plate at the end of the precast column in the upper section; the top end of the precast column in the lower section There is a cup opening at the center of the center for tenon installation, and the surface of the top end of the lower precast column is covered with a pre-embedded steel plate at the end of the lower precast column; the four side walls of the upper precast column are connected to the connecting steel plate through part of the precast bolts Unit connection, the four side walls of the prefabricated column in the lower section are connected with the double-layer connecting steel plates through part of the embedded bolts. The matching column node of the invention improves the bearing capacity and rigidity of the column connecting node. It also provides the construction method of the joint column joint and the method for determining the size of each component.

Description

technical field [0001] The invention belongs to the technical field of building assembly, and specifically relates to a fully assembled column joint connected by double steel plate bolts, and also relates to a construction method for fully assembled column joints connected by double steel plate bolts and a fully assembled column joint connected by double steel plate bolts The method for determining the size of each component of the node. Background technique [0002] First of all, the traditional prefabricated RC column connection requires on-site binding of steel bars, and the on-site pouring of concrete is greatly affected by temperature and requires curing time; second, although many domestic scholars have proposed a new connection form using steel plate hoops or steel hoop bolts, However, the deformation and energy consumption of these connection nodes are uncontrollable, and the repairable performance after the earthquake cannot be realized; or they have good deformatio...

Problems solved by technology

[0002] First of all, the traditional prefabricated RC column connection requires on-site binding of steel bars, and the on-site pouring of concrete is greatly affected by temperature and requires curing time; second, although many domestic scholars have proposed a new connection form using steel plate hoops or steel hoop bolts, However, the deformation and energy consumption of these connection nodes are uncontrollable, and the repairable performance after the earthquake cannot be realized; or they have good deformation and energy consumption performance of the connection nodes, but the structure is complicated, the production is difficult, and the cost is increased; third, the existing The steel plate hoop or steel plate hoop bolt connection also requires on-site pouring mortar or on-site welding, which increases the construction steps and difficulty
