AI Technical Summary
Existing prefabricated shear wall structures lack direct connections between upper and lower shear walls, resulting in poor stability and insufficient horizontal load-bearing capacity.
By setting up components such as connecting rods, limiting frames, pressure blocks, and bolts between the lower shear wall body and the upper shear wall body, the bolts are tightened to drive the pressure blocks to move and fix the reinforcing bars. Combined with cement injection, the upper and lower shear walls are directly connected and stably fixed.
It improves the stability of the shear wall structure, enhances its ability to withstand horizontal loads, ensures the limiting support of the upper shear wall in the X, Y and Z directions, and simplifies the problem of steel bar interference during assembly.
