Description

Technical Field

[0001] This invention belongs to the field of prefabricated building engineering technology, and in particular relates to a prefabricated shear wall installation and positioning device. Background Technology

[0002] With the rapid development of modern building technology, prefabricated modular building structures have gained widespread attention and application globally. Prefabricated modular shear wall structures, as a highly efficient, environmentally friendly, and energy-saving building form, are particularly favored by industry professionals.

[0003] Precast shear wall structures are a type of building where the main load-bearing components of the shear wall are prefabricated in a factory and then transported to the construction site for assembly. This structural form, through precise prefabrication and efficient assembly, significantly improves construction speed, reduces on-site wet work, and lowers energy consumption and environmental pollution. Furthermore, precast shear wall structures possess excellent seismic performance, overall stability, and durability, which are of great significance for improving building safety and service life.

[0004] The installation and positioning of precast shear walls often employs diagonal braces with external threads at both ends, combined with double adjusting bolts (patent CN217734932U), to achieve bidirectional fine-tuning of the connection between the wall panel and the floor slab. However, this adjustment process relies on manual operation, requiring repeated rotation of the bolts to correct installation accuracy, resulting in low efficiency. The single-point support of the diagonal braces is prone to displacement due to external disturbances, requiring multiple checks and adjustments. Furthermore, the adjusting bolts are prone to slippage between themselves and the embedded parts, and if the anchorage strength between the embedded parts and the concrete is insufficient, they may loosen, posing a safety hazard. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a precast shear wall installation and positioning device. This invention solves the core problems of conventional precast shear wall installation and positioning methods, such as excessive reliance on manual labor, insufficient connection stability, and low installation efficiency.

[0006] Therefore, the present invention is achieved through the following technical solution: an installation and positioning device for a precast shear wall, comprising a rotating limiting plate, a positioning plate, connecting bolts, adjusting shims, and pre-embedded bolts.

[0007] Preferably, in the aforementioned precast shear wall installation and positioning device, the positioning plate is fixed to the structure by pre-embedded bolts, and the connecting bolts bolt the rotating limiting plate to the positioning plate, which can rotate relative to each other along the bolted central axis.

[0008] Preferably, in the precast shear wall installation and positioning device, a matching adjusting shim is placed in the gap between the positioning plate and the rotating limiting plate for relative constraint, and the angle of the rotating limiting plate is accurately positioned by adjusting the shim.

[0009] The precast shear wall installation and positioning device includes a rotating limiting plate, a positioning plate, connecting bolts, adjusting shims, and pre-embedded bolts.

[0010] The rotating limiting plate is an L-shaped steel plate. The vertical section of the L-shaped steel plate is tilted outward at a certain angle to facilitate the smooth placement of the precast shear wall. The horizontal section of the L-shaped steel plate is fan-shaped at the end and has a protruding arc-shaped end plate in the middle. The end plate has a circular hole in the middle, and the hole diameter matches the connecting bolt. The L-shaped steel plate has a vertical web in the middle.

[0011] The positioning plate is a steel plate with a row of two round holes in the middle, the diameter of which matches the pre-embedded bolts; the middle of one end of the steel plate is a protruding arc-shaped end plate with a threaded hole in the middle, which matches the connecting bolts.

[0012] The rotating limiting plate and the positioning plate are connected and fixed by connecting bolts. The adjusting shim is used to adjust the angle of the rotating limiting plate to achieve better fit with the side of the precast shear wall. The positioning plate is fixed by pre-embedded bolts in the structure.

[0013] The present invention can achieve the following beneficial effects:

[0014] 1. This invention uses pre-embedded bolts to fix the limiting plate. Under the premise of fully considering the installation deviation of the pre-embedded bolts, the rotating limiting steel plate can be adjusted at multiple angles by placing matching adjusting shims to ensure the accurate positioning of the precast shear wall.

[0015] 2. This invention can ensure that the precast shear wall is accurately positioned in one go, significantly shortening the installation and adjustment time, greatly improving installation efficiency, effectively ensuring construction quality, and at the same time greatly reducing construction safety hazards. The installation process is more convenient, the installation accuracy is more accurate, and the operability is stronger.

[0016] 3. All components of this invention can be prefabricated in the factory. Through the flexible combination and application of multiple devices, the installation requirements of prefabricated shear walls of different forms (or sizes) can be met, making it more adaptable and having considerable long-term economic benefits.

The end of the vertical section of the L-shaped steel plate is tilted outward at a certain angle to facilitate the smooth placement of the precast shear wall.

The end plate has a circular hole in the middle, and the hole diameter matches the connecting bolt 3. The L-shaped steel plate has a vertical web in the middle.
