[0003] In existing technologies, shear walls are generally cast on-site using concrete. This results in complex construction steps and a long construction period. Furthermore, the shear walls are heavy and prone to cracking or breaking.

[0004] An existing patent (publication number: CN210597743U) discloses an assembled PEC recycled concrete beam-column and steel plate combined shear wall. The utility model is an assembled PEC recycled concrete beam-column and steel plate combined shear wall. The support beams and steel plate combined shear wall can be prefabricated in the factory. All components are welded in the factory. During construction, only the support columns need to be cast on site and the remaining parts can be assembled. The construction is simple and easy to operate; the bearing capacity is high and the structure can be quickly replaced after earthquake damage.

[0005] In response to the above problems, although the solution provided by the existing patent can be prefabricated in advance through the cooperation of components such as support beams and then assembled on site, when assembling the shear wall panels, several bolts need to be installed for fixing, resulting in low assembly efficiency and high labor intensity.

One side of the positioning blocks 606 on both sides of the outer wall of the prefabricated shear plate 603 is provided with a positioning groove 605. A material injection port 607 is provided at the front end of the prefabricated shear plate 603. The slot 601 and the slide groove 602 are perpendicular to each other.

The prefabricated shear plate 603 forms a sliding structure with the prefabricated beam 3 through the slide block 604. The prefabricated beam 3 and the prefabricated column 1 are perpendicular to each other.

[0029] By adopting the above technical solution, first, high-strength bolts are inserted into the mounting holes 5 to fix the connecting plates 2 and the receiving plates 4, thereby allowing the prefabricated columns 1 and the prefabricated beams 3 to be assembled. Subsequently, the sliders 604 of the prefabricated shear plates 603 are inserted into the slide grooves 602 through the card grooves 601 and slide, and are quickly assembled with each other. The slide grooves 602 are used to limit the position, thereby avoiding the troublesome and low efficiency of assembling multiple bolts. At the same time, the positioning blocks 606 are inserted into the positioning grooves 605 of the adjacent prefabricated shear plates 603 to improve the overall connection stability, thereby improving the stability of the shear wall. Concrete mortar is injected through the injection port 607 to increase the deadweight of the entire wall and improve stability.

[0030] Specifically, such as Figure 1 、 Figure 4 and Figure 5 As shown, a connecting hole 7 is provided on the other side of the outer wall of the prefabricated beam 3, and a supporting mechanism 8 is provided on one side of the connecting hole 7. The supporting mechanism 8 includes a prefabricated supporting frame 801, which is slidably connected to the outside of the prefabricated beam 3, and a corresponding hole 802 is provided on the outer wall of the prefabricated supporting frame 801 corresponding to the connecting hole 7.

High-strength bolts are inserted into the connecting plates 2 and the receiving plates 4 through the mounting holes 5 for assembly. The steel prefabricated shear plates 603 pass through the sliders 604 and the slots 601 into the slide grooves 602 and slide. Several prefabricated shear plates 603 are inserted into the positioning grooves 605 through the positioning blocks 606 to improve stability, so that the prefabricated shear plates 603 can be quickly assembled. Concrete mortar is injected in a countercurrent manner through the injection port 607 to improve the overall firmness and stability. The prefabricated support frame 801 is also made of steel. And slide along the prefabricated beam 3. When the prefabricated shear plate 603 is installed, the prefabricated support frame 801 is fixed by inserting high-strength bolts into the connecting hole 7 and the corresponding hole 802. Then the abutment shell 805 is inserted into the groove 803 and abuts against the empty position of the two prefabricated shear plates 603 to limit and support. At the same time, the connecting plate 804 is fixed to the prefabricated support frame 801 by bolts, so that it can be quickly assembled. The prefabricated support frame 801 prevents the prefabricated beam 3 from being subjected to excessive stress due to excessive span and provides a certain degree of support. Concrete mortar is injected in a countercurrent manner through the feed port 806 to form a complete prefabricated beam-column and steel plate combined shear wall.
