Double-steel-plate bolt connection full-assembly type column joint as well as construction method and calculation method thereof

Abstract

The invention discloses a double-steel-plate bolt connection full-assembly type column joint. The double-steel-plate bolt connection full-assembly type column joint comprises an assembly type integralcolumn, double-layer connecting steel plates are arranged on the four side walls of the assembly type integral column, the assembly type integral column comprises an upper-section prefabricated column body, a middle filling layer and a lower-section prefabricated column body, a protruding tenon is arranged in the center of the bottom end of the upper-section prefabricated column body, an upper-section prefabricated column end tenon pre-embedded steel plate is wrapped around the surface of the bottom end portion of the upper-section prefabricated column body, a cup opening for mounting the tenon is formed in the center of the top end portion of the lower-section prefabricated column body, a lower-section prefabricated column end portion cup opening pre-embedded steel plate covers the surface of the top end portion of the lower-section prefabricated column body, the four side walls of the upper-section prefabricated column body are connected with connecting steel plate units through part of embedded bolts, and the four side walls of the lower-section prefabricated column body are connected with the double-layer connecting steel plates through part of embedded bolts. According to theassembly type column joint, the bearing capacity and rigidity of the column connecting joint are improved. The invention further provides a construction method of the assembly type column joint and amethod for determining the sizes of all parts of the assembly type column joint.

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
