AI Technical Summary
Existing technologies for reinforcing shear walls after openings are complex in structure, have insufficient connection reliability, and are difficult to construct, thus failing to meet the requirements for load-bearing capacity and seismic performance after shear wall reinforcement.
The structure employs a central reinforcement structure and a side reinforcement structure. It uses components such as the first inner angle steel, the first L-shaped flat steel, the second inner angle steel, the second L-shaped flat steel, and longitudinal flat steel, which are connected by screws to form a stable whole, enhancing the cooperative stress-bearing capacity. A high-strength concrete reinforcement zone is set at the bottom of the opening.
It effectively disperses stress at openings, enhances the coordinated load-bearing capacity of shear walls, simplifies construction processes, improves construction efficiency, and enhances load-bearing and seismic performance.
