[0002] A precast shear wall is a structural wall prefabricated in a factory and is one of the main elements for providing seismic and structural strength support in a building. It is a precast concrete or steel structure wall system. Precast shear walls are widely used in construction projects, especially in multi-story and high-rise buildings. They can be part of the structural system, forming an integral seismic frame, and providing overall seismic performance through connection with other structural elements. This precast system can improve construction speed, quality control, and engineering efficiency, while reducing the demand for labor and resources in on-site construction.
[0003] However, in the current use of existing shear walls in buildings, multiple shear walls are usually spliced together to make the building stable. However, when splicing multiple shear walls, traditionally, bolts or casting methods are used for splicing. This method is not only inconvenient to operate but also increases the fatigue of workers.

A plurality of second steel bars are arranged in the inner cavity of the second precast wall. Splicing components are arranged on both sides of the first precast wall. The splicing components are used for quickly splicing and using the second precast wall. Hoisting rings are connected to both sides of the top of the second precast wall.
[0007] In order to achieve the effect of quickly splicing and using the second precast wall, as the precast shear wall provided by the utility model, preferably, the splicing component includes a chute. One side of the chute is connected to the first precast wall. Sliders are slidably inserted in the inner cavity of the chute. One side of the slider is connected to the second precast wall.
[0008] In order to achieve the effect of fixing and positioning the slider, as the precast shear wall provided by the utility model, preferably, reinforcing blocks are connected to both ends of the slider. One side of each reinforcing block is connected to the second precast wall.
[0009] In order to achieve the effect of strengthening the lifting ring, as the precast shear wall provided by the present utility model, preferably, fixed blocks are connected to both sides of the lifting ring, and the bottoms of the fixed blocks are connected to the second precast wall.
[0010] In order to achieve the effect of supporting the first precast wall and the second precast wall, as the precast shear wall provided by the present utility model, preferably, support rods are connected to both ends of the first precast wall and the second precast wall through rotating shafts, and the bottoms of the support rods are connected to the ground through rotating shafts.

The precast shear wall includes a first precast wall 1. A second precast wall 2 is provided on one side of the first precast wall 1. A plurality of first steel bars 3 are welded and fixed inside the first precast wall 1 to increase firmness. A plurality of second steel bars 4 are welded and fixed inside the second precast wall 2. Splicing components 5 are provided on both sides of the first precast wall 1. The splicing components 5 are used for quickly splicing the second precast wall 2. Hoisting rings 6 are bolted and fixed on both sides of the top of the second precast wall 2.
[0019] In the specific implementation process, as Figure 1 Figure 2 and Figure 3 shown, the splicing component 5 includes a chute 51.

One side of the slider 52 is bolted and fixed to the second precast wall 2;
[0020] When the second precast wall 2 needs to be quickly spliced, first use a steel cable to hoist it into the inner cavity of the hoisting ring 6 and lift it. At this time, align the slider 52 with the inner cavity of the chute 51, then slowly release the steel cable and move it downward slowly. While moving, drive the slider 52 to be slidably inserted into the inner cavity of the chute 51. At this time, the second precast wall 2 can be quickly spliced and fixed, so as to effectively achieve the effect of quickly splicing the second precast wall 2.

[0027] The working principle of the precast shear wall provided by the present utility model is as follows:
[0028] During use, when it is necessary to quickly splice and use the second precast wall 2, first use a steel cable to lift it into the inner cavity of the lifting ring 6 and raise it.
