Abstract

The invention relates to an assembling type concrete filled steel tube shear wall splitting and an assembling connection structure and assembling connection method. The structure comprises prefabricated concrete filled steel tube frame pillars, prefabricated shear walls, prefabricated flange walls and a cast-in-place floor; the upper ends of the prefabricated shear walls and the prefabricated flange walls are welded to rebar sleeves and steel tube sleeves respectively, the rebar sleeves and the steel tube sleeves are mutually embedded into rebar protruding segments and steel tube protruding segments respectively, and the upper prefabricated shear wall and the lower prefabricated shear wall are connected as a whole through pouring grouting materials into the sleeves and connected horizontal gaps; the prefabricated shear walls are separated from the prefabricated flange walls at the prefabricated concrete filled steel tube frame pillars, and by arranging sealed U-shaped connection ribs in the frame pillars in a protruding mode in the prefabricated shear walls and the adjacent prefabricated flange walls, erection formwork cast-in-place concrete enables the prefabricated shear walls and the adjacent prefabricated flange walls to form a whole. The assembling type concrete filled steel tube shear wall splitting and the assembling connection structure and assembling connection method greatly reduces the wet construction such as cast-in-place concreting to the largest extent, improves the assemblage degree of practical engineering, and the integrality of the assembly type shear wall structure can be guaranteed.

Description

technical field [0001] The invention relates to a prefabricated concrete shear wall structure, in particular to a disassembled and assembled connection structure and an assembling and connecting method of a prefabricated steel pipe concrete shear wall. Background technique [0002] At present, ordinary residential buildings in our country basically adopt the cast-in-place method. However, the cast-in-place structural system obviously has disadvantages such as high cost and long construction period. In order to meet the requirements of green production and sustainable development, prefabricated houses built in an industrialized manner have shorter construction periods, stable, reliable, green, and energy-saving quality, and can greatly relieve market pressure. However, the existing technology for prefabricated concrete shear wall structures is generally applied to pure shear wall structures. There are few researches on concrete shear wall structure. The current practice of...
