Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, specifically to a self-locking sleeve hybrid connection prefabricated shear wall. Background Technology

[0002] Prefabricated shear wall structures are one of the most commonly used structural forms in mid- to high-rise buildings. They primarily bear horizontal loads and vertical loads (gravity) caused by wind or earthquakes, preventing shear failure and possessing high stiffness, strength, and stability. Prefabricated shear wall structures are assembled from different wall panels, resulting in numerous horizontal joints between the shear walls. The presence of these horizontal joints affects the mechanical properties and stress state of the shear wall structure. Therefore, horizontal joints are a key concern in prefabricated concrete shear wall structures and also one of their weakest points.

[0003] A scientifically sound and reasonable joint design helps resist external loads and deformations, improves the overall stability of the structure, enhances the collaborative working ability of components, and ensures the integrity of the structure and construction efficiency. Currently, most horizontal construction joints generated during the vertical connection of prefabricated shear wall components are straight joints, which significantly impacts the integrity and seismic resistance of the connected shear wall, resulting in weak structural performance. Therefore, it is urgent to design prefabricated shear walls with self-locking sleeve hybrid connections to solve the above problems. Utility Model Content

[0014] By adopting the above-mentioned utility model, the steel inner mold is used as a mortise template when pouring shear walls. After the shear wall is cured and formed, it is not removed and serves as a permanent steel inner mold. The steel outer mold with tenons is combined with the steel inner mold embedded in the mortise, which makes the precision controllable, greatly reduces the installation difficulty, and avoids installation difficulties caused by insufficient precision.

[0015] Preferably, both sides of the groove are provided with mating grooves, and both ends of the bottom of the mounting plate are fixedly installed with mating buckles, the size of which is adapted to the mating groove.
