Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a prefabricated hollow shear wall structure. Background Technology
[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are walls in buildings or structures that primarily bear horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear failure. They are typically made of reinforced concrete.
[0003] In existing prefabricated shear walls, it is inconvenient to align and connect adjacent shear walls, requiring multiple adjustments to determine the appropriate assembly position, resulting in low assembly efficiency. Therefore, there is a need for a prefabricated hollow shear wall structure with good assembly effect and high assembly efficiency. Utility Model Content
[0004] The main purpose of this utility model is to provide a prefabricated hollow shear wall structure to solve the problems existing in the prior art.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A prefabricated hollow shear wall structure includes wall panels with assembly grooves. Each assembly groove includes a first groove and a second groove. The first groove has a trapezoidal cross-section, and the second groove has a rectangular cross-section. The first groove is located on the side surface of the wall panel, and the second groove is located at the end of the first groove away from the side wall of the wall panel. The second groove is connected to the short side of the trapezoidal first groove. A connecting structure is provided on the side of the wall panel to connect two adjacent wall panels.
[0007] Furthermore, the connection structure includes a rectangular plate groove and a pre-embedded bolt. The rectangular plate groove is located on the side of the wall panel, and the pre-embedded bolt is located inside the rectangular plate groove. The rectangular plate grooves of two adjacent wall panels are connected by a rectangular steel plate, and the rectangular steel plate is connected to the pre-embedded bolt by a nut.
[0008] Furthermore, the connection between the first groove and the second groove is an arc-shaped structure.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] Prefabricated hollow shear wall structures are easier to construct. Adjacent shear wall sections are connected by assembly slots, making the splicing between walls more accurate and convenient, thus improving construction efficiency.
[0011] Shear wall structures formed by connecting structural combinations have higher overall stability and better seismic resistance. Attached Figure Description

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0017] Example
[0018] Combination Figure 1-3 This utility model provides a prefabricated hollow shear wall structure, including a wall panel 1. The wall panel 1 is provided with an assembly groove 2, which includes a first groove 21 and a second groove 22. The first groove 21 has a trapezoidal cross-section, and the second groove 22 has a rectangular cross-section. The first groove 21 is located on the side surface of the wall panel 1, and the second groove 22 is located at the end of the first groove 21 away from the side wall of the wall panel 1. The second groove 22 is connected to the short side of the trapezoidal first groove 21. A connecting structure 3 is provided on the side of the wall panel 1, which is used to connect two adjacent wall panels 1.
[0019] The mounting groove 2 on the wall panel 1 can be either a straight line or a broken line. A straight mounting groove 2 is suitable for wall structures that only need to connect to other wall panels 1 on one side, while a broken line mounting groove 2 is suitable for wall structures that need to connect to other wall panels 1 on at least two sides. With the setting of the mounting groove 2, the insertion and assembly of adjacent wall panels 1 is more convenient.
[0020] Each assembly slot 2 may or may not include an extended steel reinforcement structure.
[0021] When assembling two adjacent wall panels 1, the assembly insertion end with steel bars of one wall panel 1 is inserted into the assembly groove 2 of the other wall panel 1. The trapezoidal structure of the first groove 21 facilitates the entry of the insertion end. Guided by the inclined surface of the trapezoidal structure of the first groove 21, the insertion end enters the second groove 22 to achieve plug-in assembly. After plug-in and fixing, grouting can be performed.
[0022] The connection structure 3 includes a rectangular plate groove 31 and a pre-embedded bolt 32. The rectangular plate groove 31 is located on the side of the wall panel 1, and the pre-embedded bolt 32 is located inside the rectangular plate groove 31. The rectangular plate grooves 31 of two adjacent wall panels 1 are connected by a rectangular steel plate, and the rectangular steel plate is connected to the pre-embedded bolt 32 by a nut.
[0023] As an optimization, the connection between the first groove 21 and the second groove 22 is an arc-shaped structure, which can ensure that the two adjacent wall panels are inserted more smoothly.
[0024] The prefabricated hollow shear wall structure disclosed in this utility model is more convenient to construct. The assembly groove 2 connects two adjacent shear wall bodies, making the splicing between the wall bodies 1 more accurate and convenient, thus improving construction efficiency. The shear wall structure formed by the connection structure 3 has higher overall stability and better seismic resistance.
[0025] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
