Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shear walls, in particular to a prefabricated building shear wall structure. BACKGROUND

[0002] In strong wind weather or when an earthquake occurs, high-rise buildings are subjected to a large impact in the horizontal direction, and a certain amplitude of swing or lateral displacement occurs, which exerts a great pressure on the root of the building, making the connection between the building and the ground prone to breakage, and ultimately leading to the collapse of the building. The shear wall, also known as a wind-resistant wall, an earthquake-resistant wall or a structural wall, is a wall that mainly bears the horizontal load caused by wind load or earthquake action in a building or structure, and can bear most of the horizontal load through its bending deformation, thereby sharing the pressure at the connection between the root of the building and the ground, effectively preventing shear failure of the building structure, and thus is widely used.

[0003] In the assembly process of the existing prefabricated shear wall, sleeve grouting connection is a widely used connection method. A certain length of steel bar is reserved outside the shear wall, a sleeve is reserved inside the shear wall, the steel bar is inserted into the sleeve and high-strength grouting material without shrinkage is poured into the sleeve, and the steel bar and the sleeve are fixedly connected together after the grouting material hardens, thereby realizing the connection and assembly of adjacent shear walls.

[0004] However, in the actual use process of the existing sleeve grouting connection, an external support structure is usually used to support the shear wall being assembled during the grouting process. However, during the process from the completion of grouting to the hardening of the grouting material, the external support structure is prone to slight shaking due to external forces, thereby easily affecting the connection stability of the steel bar and the sleeve after the grouting material hardens, and further affecting the overall stability of the shear wall after assembly.
