Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to an impact-resistant prefabricated shear wall. Background Art

[0002] A precast shear wall is a type of shear wall structure in which components (such as concrete panels and steel plates) are prefabricated in a factory before construction. It primarily consists of precast concrete panels, precast concrete columns, connecting steel bars to panels, and grouting between columns and panels. Through the assembly of precast components and on-site grouting, the precast shear wall forms a load-bearing wall structure.

[0003] A search revealed a utility model patent with Chinese patent publication number CN211899072U, which discloses a prefabricated shear wall, relating to the field of building construction technology. The main technical features of the prefabricated shear wall are as follows: the prefabricated shear wall comprises a lower wall and an upper wall, wherein vertical steel bars are arranged at intervals along the length of the lower wall on the top surface of the lower wall, the prefabricated shear wall comprises sleeves arranged at intervals along the length of the upper wall on the bottom surface of the upper wall, the sleeves being located within the upper wall, the side walls of the upper wall comprising first grouting holes, a connector fixed to the steel bars within the lower wall on the top surface of the lower wall and located between the two vertical steel bars, the bottom surface of the upper wall comprising a receiving groove, the receiving groove comprising a connecting frame for engaging with the connector and being fixedly connected to the steel bars within the upper wall, and the side walls of the upper wall comprising connecting pipes for securing the connector to the connecting frame. The prefabricated shear wall has the advantage of enhancing the firmness of the shear wall.

[0004] Upon searching, the above patents have been found to have dealt with the splicing of prefabricated shear walls, but the structure has failed to deal with the impact resistance of the shear walls. Therefore, the structure has relatively weak resistance to external impacts. Utility Model Content

[0012] Preferably, a plurality of pouring holes are provided at the upper ends of the first wall and the second wall, the plurality of pouring holes are arranged at equal distances, and the pouring holes are connected to the cavity.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The operator moves Wall 1 to the designated location for installation, and then installs Wall 2 on one side of the wall. At this time, Wall 2 fits against one side of the wall. Then, push Wall 2 so that the fixing block slides into the through groove and the protrusion, thereby performing a preliminary snap connection between Wall 1 and Wall 2.

[0022] Reference Figure 1-4 A shock-resistant prefabricated shear wall includes a wall 1, a plate 2 is fixedly connected to the side wall of the wall 1, and the plate 2 is located at the lower end of the side wall of the wall 1. A plurality of protrusions 3 are distributed in a rectangular array on the side wall of the wall 1, and a through groove 4 is provided inside the protrusion 3; a wall 2 7 is provided on the side wall of the wall 1, and the side wall of the wall 2 7 is fitted with the side wall of the plate 2, and the side wall of the wall 2 7 is fixedly connected to the plate 2 8, and the side wall of the plate 2 8 is fitted with the side wall of the wall 1, and a plurality of fixed blocks 10 are distributed in a rectangular array on the side wall of the wall 2 7, and the fixed blocks 10 are slidably connected to the through groove 4. A plurality of reinforcing ribs 14 are provided inside the wall 1 and the wall 2 7. The operator moves the wall 1 to the designated installation location. Then install wall 2 7 on the side wall of wall 1. At this time, wall 2 7 is fitted with the side wall of wall 1. Then push wall 2 7 so that the fixing block 10 slides into the through groove 4 and the protrusion 3, thereby performing a preliminary snap-fit ​​connection between wall 1 and wall 2 7. After wall 1 and wall 2 7 are connected, a cavity is formed in the middle part. The upper and lower ends of the cavity are sealed by plate 1 2 and plate 2 8. Then, the mixed concrete is poured into the cavity to fill the inside of the cavity so that the concrete fills the gap between the fixing block 10 and the protrusion 3. At the same time, by installing reinforcing ribs 14 inside wall 1 and wall 2 7, the impact resistance of wall 1 and wall 2 7 is improved.

[0023] A plurality of pouring holes 9 are provided through the upper end of the second plate 8 , and the plurality of pouring holes 9 are arranged at equal intervals. Concrete is transported into the cavity through the plurality of pouring holes 9 to fill the gap between the fixing block 10 and the protrusion 3 .
