[0002] With the vigorous popularization and promotion of the national fabricated building, local and enterprises actively respond and implement, prefabricated building occupies a proportion more and more in industry and civil building. At the same time, many problems also appear in the hoisting process of the fabricated shear wall. The general fabricated shear wall structure is connected by post-poured concrete structure between the prefabricated wall, so the prefabricated wall will reserve the steel bar laterally, and the reserved closed steel bar will appear the phenomenon of "fighting" when hoisting the adjacent shear wall, which affects the construction progress and greatly reduces the efficiency of prefabricated hoisting operation.

[0003] Because of the vertical steel bar or grouting sleeve at the installation plug-in place of the prefabricated shear wall and the bottom plate, when completing the installation of single prefabricated shear wall plate, the reserved closed stirrup of the adjacent shear wall plate will interfere with the reserved closed stirrup of the last shear wall plate, and the phenomenon of "fighting" appears. In the field hoisting, the reserved lateral closed stirrup is often bent and pulled and pulled, which realizes the requirement of field hoisting and speeds up the engineering construction progress, but also affects the mechanical properties and durability of the steel bar.

[0004] The technical problem to be solved by the utility model is that in order to overcome the deficiencies in the prior art, a combined prefabricated shear wall installation structure is provided.

[0005] The technical scheme adopted by the utility model to solve the technical problem is that a combined prefabricated shear wall installation structure comprises at least two prefabricated shear wall plates which are sequentially assembled laterally, and the left and right sides of the prefabricated shear wall plate are provided with reserved closed stirrups, and the reserved closed stirrups of the two adjacent prefabricated shear wall plates at the butt joint are arranged in a staggered manner.

[0006] The two adjacent prefabricated shear wall plates are connected through a reinforcing channel steel group.

[0007] Further, the reinforcing channel steel group comprises upper and lower reinforcing channel steel groups arranged on the front and / or back of the prefabricated shear wall plate.

[0008] Further, the prefabricated shear wall plate and the reinforcing channel steel are provided with corresponding reserved holes and are connected through bolts.

[0009] The precast shear wall plate is usually 200mm thick, and the punching position of the high-strength bolt must avoid the embedded steel mesh, and the selection of the reinforcing channel steel and the high-strength bolt is determined according to the size of the wall plate and through calculation. Meanwhile, according to the requirements of the project, a 10mm gap is left between the closed stirrup and the adjacent shear wall at the staggered contact position.

[0010] Further, the upper end of the shear wall plate is provided with vertical steel bars.

[0011] The utility model discloses utilize the bending tensile capacity of reinforcing channel steel and the shearing capacity of high-strength bolt, realize the integral hoisting of precast shear wall.

[0012] The utility model has the advantages that: the utility model realizes that a plurality of precast shear wall plates are assembled into a whole in advance through structure improvement, avoids the mutual interference of lateral closed stirrups when hoisting the precast shear wall alone, avoids the forced bending and pulling of the closed stirrup in construction operation, enhances the integrity of adjacent precast shear wall bodies, and greatly improves the construction efficiency of assembly type vertical operation hoisting.
