The lower end corresponds up and down with the positions of the bolt holes. By setting the number of bolt holes to two, two leveling and positioning devices can be placed to further improve the accuracy of positioning in the horizontal direction between the upper and lower assembled shear wall structures.

As a preferred solution of the present invention, a square hole is arranged on the upper part of each vertical through hole. By setting a square hole on the upper part of the vertical through hole, the wedge is wedged into the gap between the steel pipe and the vertical through hole, so as to ensure the overall verticality of the upper and lower assembled shear wall structures.

As a preferred solution of the present invention, the side length of the square hole is 7-15 mm longer than the diameter of the vertical through hole.

As a preferred solution of the present utility model, the side length of the square hole is 10 mm longer than the diameter of the vertical through hole.

As a preferred solution of the present invention, several evenly arranged ring bars are respectively arranged at the upper and lower ends of the main body of the shear wall.

To sum up, the advantages of the prefabricated shear wall structure and its installation method of the present invention are that the prefabricated shear wall structure can be accurately and quickly positioned horizontally, has good integrity, is quick to install, and does not need support by diagonal braces, saving Auxiliary material costs.

Detailed ways

As shown in Figures 1 to 4, the utility model's assembled shear wall structure includes a shear wall main body 1, and at least one vertical through hole 2 is arranged inside the shear wall main body 1, and the vertical through hole 2 The number is preferably two or three, (three are taken as an example in the figure) three vertical through holes 2 are evenly arranged inside the main body of the shear wall 1, and the three vertical through holes 2 can strengthen the upper and lower two assembled shears. Stability of force-wall structural connections. A square hole 5 is arranged on the upper part of each vertical through hole 2, and the side length of the square hole 5 is 7-15 mm longer than the diameter of the vertical through hole, preferably 10 mm.

At least one bolt hole 3 is provided at the upper end of the shear wall main body 1, and at least one reserved guide hole 4 is provided at the lower end of the shear wall main body 1, and the position of the reserved guide hole 4 corresponds to the position of the bolt hole 3 up and down. The number of the bolt holes 3 is two, and the two bolt holes 3 are evenly distributed on the upper end of the shear wall main body 1, and the number of the reserved guide holes 4 is the same as the number of the bolt holes 3, which are arranged at the lower end of the shear wall main body 1 and It corresponds up and down to the position of the bolt hole 3. The bolt hole 3 can be placed into a leveling and positioning device to further improve the accuracy of positioning in the horizontal direction between the upper and lower assembled shear wall structures.

A number of uniformly arranged ring bars 6 are respectively arranged at the upper and lower ends of the shear wall main body 1 . The vertical through hole 2 is used to insert steel pipes before pouring, so as to temporarily connect the upper and lower assembled shear wall structures in the vertical direction, and the bolt holes 3 and reserved guide holes 4 are used to accommodate leveling and positioning devices 7. Position and adjust the upper and lower assembled shear wall structures in the horizontal direction. The setting of the ring reinforcement 6 serves to strengthen the connection between the upper and lower assembled shear wall structures.

The installation method of the prefabricated shear wall structure of the utility model is as follows:

a. Place a steel pipe in the vertical through hole 2 of the lower prefabricated shear wall, and install a leveling and positioning device 7 in the bolt hole 3;

b. Hoist the through hole of the upper prefabricated shear wall to the installation position along the steel pipe, and insert the upper end of the leveling and positioning device into the reserved guide hole 4 to realize the horizontal position positioning of the upper and lower prefabricated shear walls; The upper shear wall acts as a temporary support to keep it from overturning;
