Abstract
Description
Technical Field
[0001] This utility model relates to precast walls, specifically to a hollow shear wall. Background Technology
[0002] The use of precast hollow shear walls is becoming increasingly widespread, especially in rural areas where they are increasingly used to construct buildings. Existing hollow shear walls have one or more of the following problems: 1. The wall panels are large, making transportation inconvenient; 2. Leakage is prone to occur at the junctions between the shear wall and beams, adjacent shear walls, or other structures, and the connection strength is low. To solve these problems, this utility model provides a hollow shear wall. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a hollow shear wall, which mainly solves the problems of water leakage and low connection strength at the connection between the shear wall and beams and other structures.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a hollow shear wall, including a wall panel, with through holes running vertically through the wall panel, and a connecting groove on the upper end face of the wall panel, the connecting groove penetrating the two end faces of the wall panel not used as the wall surface and communicating with each through hole, and reinforcing steel members installed inside the wall panel, extending out of the two end faces of the wall panel not used as the wall surface, and at least one connecting hole is vertically distributed on the end face of the wall panel not used as the wall surface. The connecting groove is located on the top surface of the wall panel and communicates with each through hole. When in use, the wall panel is cast integrally with the horizontal and vertical beams, and the connecting groove forms a recessed gap, which has a waterproof effect and improves the connection strength between the wall panel and the horizontal beams and other structures.
[0005] As an optional technical solution of this utility model, at least two through holes are provided in the wall.
[0006] As an optional technical solution of this utility model, the connecting groove is an arc-shaped groove, and adjacent through holes are connected through the connecting groove. The connecting groove is in the form of an arc-shaped groove, and when the hollow shear wall is used, an arc-shaped concave gap is formed at the connecting groove by pouring concrete, resulting in good waterproofing.
[0007] As an optional technical solution of this utility model, a lifting ring is provided on the wall panel.
[0008] As an optional technical solution of this utility model, a steel reinforcement skeleton is provided inside the wall panel. The steel reinforcement skeleton extends out of the wall panel and is not used as the two end faces of the wall surface, or each steel reinforcement component is connected to the steel reinforcement skeleton.
[0009] As an optional technical solution of this utility model, the connecting hole is an flared hole, which facilitates demolding during wall panel manufacturing.
[0010] As an optional technical solution of this utility model, the connecting hole is connected to the adjacent through hole.
[0011] As an optional technical solution of this utility model, at least two wall panels are used, which are stacked vertically, and the through holes of adjacent wall panels correspond to and are interconnected. The combination of multiple wall panels facilitates the transportation of wall panels in rural areas with width and height restrictions.
[0012] Compared with the prior art, the advantages of this utility model are as follows: 1. A connecting groove is provided at the top of the wall panel, which runs through the left and right ends of the wall panel and is connected to each through hole. When the wall panel is in use, the concrete poured at the connecting groove is integrated with the adjacent through holes and the upper beam or the upper wall panel, which not only improves the structure of the formed wall, but also forms a recessed gap between the concrete and the connecting groove, which can also play a waterproof role and prevent rainwater from outside the wall from entering the room through the gap; 2. The hollow shear wall can be used in combination. When used in combination, the wall panels are stacked and the through holes of the adjacent wall panels are connected respectively. The shear wall can be disassembled during transportation for convenient transportation. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0018] like Figure 1 and Figure 2As shown, a hollow shear wall includes a wall panel 1. Through holes 2 are provided within the wall panel 1, vertically arranged and penetrating the upper and lower surfaces of the wall panel 1. Preferably, there are two or more through holes 2, distributed along the left-right direction of the wall panel 1. A connecting groove 3 is provided on the upper surface of the wall panel 1, penetrating the left and right surfaces of the wall panel 1 along the left-right direction and communicating with each through hole 2. The left and right surfaces of the wall panel 1 are its non-wall surfaces. Reinforcing steel members 4 are provided within the wall panel 1, extending from the left and right surfaces of the wall.
[0019] In this embodiment, when the shear wall is installed and used, the wall panel 1 is placed in the middle frame formed by the steel reinforcement frames of the two horizontal beams and the two vertical beams. The steel reinforcement structure is inserted into the through hole 2. The steel reinforcement structure is connected to the steel reinforcement frames of the upper and lower horizontal beams. The steel reinforcement members 4 extending from the left and right ends of the wall panel 1 are respectively connected to the steel reinforcement frames of the two vertical beams. When the concrete is poured, the concrete of the horizontal beams and the through hole 2 are connected and form a whole. The wall panel 1 and the horizontal beams form a stable wall structure.
[0020] At least one connecting hole 5 is vertically distributed on the left and right end faces of wall panel 1. The connecting hole 5 is formed by a mold during the molding of wall panel 1. To facilitate demolding, the connecting hole 5 can be set as a flared hole in the shape of a truncated pyramid or other shapes. The connecting hole 5 is located in the position corresponding to the through hole 2. The connecting hole 5 can be set to communicate with the adjacent through hole 2, or it can be set to not communicate with the adjacent through hole 2. In the latter case, since the separation between the connecting hole 5 and the through hole 2 is relatively thin, it can be easily broken through the connecting hole 5 and the through hole 2 if necessary in actual use. After the connecting hole 5 and the through hole 2 are connected, the concrete of the vertical beam and the through hole 2 can be connected when pouring concrete, which improves the connection strength between the wall panel and the vertical beam.
[0021] The connecting groove 3 provided on the upper surface of the wall panel 1 can connect two adjacent through holes 2. The concrete of the two adjacent through holes 2 is connected through the connecting groove 3 and can form a whole with the concrete of the upper beam. The connecting groove 3 is preferably a U-shaped groove with an arc-shaped inner wall. Since the connecting groove 3 at the top of the wall panel 1 is recessed, the gap between the connecting groove 3 and the concrete is in the form of a concave arc. External rainwater is not easy to enter the room through the concave arc gap and cross the connecting groove 3, thus achieving a waterproof effect.
[0022] A steel reinforcement cage can also be provided inside the wall panel 1 to strengthen the structure of the wall panel 1. In some optional embodiments, some of the steel bars of the steel reinforcement cage extend out of the left and right end faces of the wall panel 1 for connection with the vertical beam when the wall panel 1 is installed and used. In other optional embodiments, the steel bar 4 passes through the interior of the wall panel 1 and is connected to the steel reinforcement cage inside the wall panel 1.
[0023] The wall panel 1 is also equipped with a lifting ring for easy lifting during production and use.
[0024] Please see Figure 2 In some embodiments, the hollow shear wall includes at least two wall panels 1, and multiple wall panels 1 are used in combination. Taking two wall panels 1 as an example, the two wall panels 1 are stacked vertically, and the through holes 2 of the upper wall correspond to and communicate with the through holes 2 of the lower wall. In use, the two walls are combined and placed in the middle frame formed by the steel reinforcement frames of the two horizontal beams and the two vertical beams. The steel reinforcement structure passes through the through holes 2 of the two wall panels 1 and is connected to the steel reinforcement frames of the upper and lower horizontal beams. The steel reinforcement members 4 extending from the left and right ends of each wall panel 1 are connected to the steel reinforcement frames of the two vertical beams, and then the wall is poured. The junction of the two wall panels 1 is connected and waterproofed through the connecting groove 3 of the lower wall.
[0025] In this embodiment, the hollow shear wall includes at least two wall panels 1. The wall panels 1 are assembled and cast together with the horizontal beams and vertical beams to form a wall. During transportation, each wall panel 1 can be separated, which can effectively solve the transportation problems caused by road width and height restrictions. Moreover, since the height of the wall is relatively low compared to the original wall, the load on the crane can be reduced during construction.
