A prefabricated assembly shear wall vertical joint connection structure and its construction method

Abstract

The present invention provides a prefabricated assembly type shear wall vertical slit connecting structure which comprises a left side shear wall, left side pre-embedded profile steel, a right side shear wall, right side pre-embedded profile steel, and a plurality of split bolts. The left side pre-embedded profile steel and the right side pre-embedded profile steel are disposed between the left side shear wall and the right side shear wall and have the same structure. The left side pre-embedded profile steel comprises a side plate, a front side plate and a rear side plate, the front side plate and the rear side plate are disposed at front and rear positions of the side plate, each of the front side plate and the rear side plate is inwardly provided with a groove, and the grooves are provided with a plurality of bolt holes. The split bolts are disposed in the bolt holes to lock and fix the left side pre-embedded profile steel and the right side pre-embedded profile steel. The present invention also provides a construction method of the prefabricated assembly type shear wall vertical slit connecting structure. The connecting structure is high in bearing capacity, high in stiffness, good in seismic ductility, excellent in integrity, convenient in construction and good in construction quality, and concrete is effectively restrained.

Description

Technical field [0001] The invention relates to the technical field of prefabricated and assembled concrete structures in civil engineering, in particular to a prefabricated and assembled shear wall vertical joint connection structure and a construction method thereof. Background technique [0002] The traditional cast-in-place construction method is low in industrialization, poor construction conditions, time-consuming and laborious, common quality problems are difficult to eradicate, and safety accidents occur from time to time, which is not conducive to energy conservation and environmental protection. The use of prefabricated structures can save energy, water, and materials, greatly reduce construction waste, reduce noise pollution, reduce labor consumption and intensity, effectively improve the construction environment and improve project quality. The application of prefabricated concrete structures can achieve the goal of energy saving and emission reduction, improve the pe...

Problems solved by technology

In the traditional prefabricated shear wall structure, the vertical joint connection is mainly through the reserved steel bar of the prefabricated shear wall, which is connected with the longitudinally stressed steel bar at the vertical joint position, and then the formwork is erected and the concrete is poured afterwards. This vertical joint connection technology exists The following problems: the connection of steel bars is difficult, and the concrete needs to be poured with vertical formwork. The process is complicated, the construction is difficult, the construction period is long, and the quality is difficult to guarantee, which affects the integrity of the connection and the mechanical performance

However, this kind of connection only relies on the connectors at the joints, the steel is not continuous in the vertical direction, the concrete is not restrained, it is easy to crack and fall under the load, the overall mechanical performance is insufficient, and it is still necessary to install the formwork before proceeding pouring concrete
