Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shear wall assembly construction, in particular to a kind of prefabricated shear wall connecting mechanism and method thereof. BACKGROUND

[0002] Shear wall (shear wall) is also called wind-resistant wall, anti-seismic wall or structural wall. The wall in building or structure mainly bears horizontal load and vertical load (gravity) caused by wind load or earthquake action, to prevent structural shear (shear) damage. Also known as anti-seismic wall, generally made of reinforced concrete.

[0003] It is divided into plane shear wall and cylinder shear wall. Plane shear wall is used in reinforced concrete frame structure, raised floor structure, beamless floor system. To increase the stiffness, strength and anti-collapse ability of structure, in some parts, precast reinforced concrete shear wall can be cast-in-place or assembled. Cast-in-place shear wall is poured at the same time with surrounding beam and column, and has good integrity. Cylinder shear wall is used in high-rise building, high-rise structure and suspension structure, and is surrounded by interval wall of elevator room, stairwell, equipment and auxiliary room. The cylinder wall is cast-in-place reinforced concrete wall, which has higher stiffness and strength than plane shear wall and can bear larger horizontal load.

[0004] All or part of precast shear wall structure realizes the overall connection of structure through vertical joint node area post-poured concrete and horizontal joint node area post-poured concrete belt or ring beam. This kind of shear wall structure has high industrialization degree. However, the assembly precision and quality of precast shear wall seriously affect the stability and seismic capacity of the whole building structure when it is assembled with existing wall. The quality requirement of connecting mechanism is higher during assembly. Auxiliary positioning is carried out by connecting piece during assembly process, which can effectively improve the assembly precision of shear wall. The existing prefabricated shear wall does not use auxiliary connecting piece during assembly process, which leads to low assembly precision. Therefore, the present application provides a kind of prefabricated shear wall connecting mechanism and method thereof. SUMMARY

During assembly, the fixed end and connecting end are first aligned and matched. Then, by swinging the lever back and forth, the fixed end and connecting end are gradually brought closer together, facilitating operation and effectively reducing the difficulty of operation. During the mating process between the fixed end and connecting end, pressure detection is used to determine whether the fit between the fixed end and connecting end is complete and whether there are any gaps. The location of any gaps can be determined, and adjusting the threaded rod in the corresponding location can achieve tightening, ensuring stable assembly between the shear walls and effectively improving the overall strength and mechanical properties of the prefabricated shear wall. During the assembly process, the influence of the shear wall's center of gravity and weight on the connecting mechanism is fully considered, and the assembly point is accurately calculated to ensure that each connecting mechanism is subjected to uniform force, facilitating assembly alignment.
