Description

Technical Field

[0001] The utility model belongs to the technical field of modular buildings, and in particular relates to a composite shear wall. Background Art

[0002] Prefabricated buildings, due to their short construction cycles and minimal environmental impact, have become a key direction for achieving green building and industrialization. Modular buildings, with their highest assembly rate and highest degree of industrialization, have become a key area of ​​transformation for the construction industry. The development of composite shear walls is crucial to the development of modular buildings. In concrete modular buildings, the separation of modules results in the internal walls of the structure being split into two separate modules. To save materials, the walls of the two modules typically have a central cavity. The two prefabricated walls are then combined into a composite shear wall using cast-in-place concrete. Because pouring concrete into the cavity creates horizontal pressure, tie bolts must be installed during pouring, as in traditional wall construction methods. In modular buildings, the interior is already finished, and installing tie bolts would damage the finish, reducing the practicality of modular buildings. Patent CN117127714A proposes an internal tie system with bolted connecting rods. This prevents damage to the finish during the casting of the composite wall's central cavity.

[0003] However, in this system, the installation gap left to facilitate the installation of the tension connecting rods will be squeezed under the action of horizontal pressure when pouring concrete, making the wall pouring thickness thicker than the designed thickness. Utility Model Content

[0035] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0036] like Figure 1-7 As shown, the present invention provides a composite shear wall, comprising a connection structure 1, a first wall form 2, a second wall form 3, an operating rod 4 and a concrete layer (not shown in the figure). Figure 1 、 Figure 5-7 As shown, the first wall formwork 2 and the second wall formwork 3 are arranged opposite to each other, and the connecting structure 1 is installed between the first wall formwork 2 and the second wall formwork 3 so that the first wall formwork 2 and the second wall formwork 3 form a counter-tension.

[0037] Specifically, a plurality of first opening slots 21 are provided on the surface of the first wall form 2 opposite to the second wall form 3, and the plurality of first opening slots 21 are arranged transversely. A plurality of second opening slots 31 are provided on the surface of the second wall form 3 opposite to the first wall form 2, and the plurality of second opening slots 31 are arranged transversely. The plurality of first opening slots 21 correspond to the plurality of second opening slots 31 one by one. Figure 7 As shown, the connection structure 1 includes a plurality of connection members 11 and two channel steels 12. Figure 1-2 、 Figure 5-7 As shown, two channel steels 12 are parallel and vertically arranged in the first wall form 2 and the second wall form 3 with their open ends facing each other. Figure 7As shown, multiple connectors 11 are arranged parallel to each other and arranged along the height direction of the two channel steels 12 between the two channel steels 12, with the ends of the connectors 11 respectively located within the two channel steels 12. The first opening slot 21 and the second opening slot 31 are adapted to the shape of the channel steels 12. The connection structure 1 is installed between the first wall form 2 and the second wall form 3, with the two channel steels 12 respectively located within the corresponding first opening slot 21 and second opening slot 31, so that the first wall form 2 and the second wall form 3 form a tensioning relationship.

[0038] like Figure 1 、 Figure 5-7 As shown, the connecting member 11 includes a connecting rod 111 and a first end plate 112 and a second end plate 113 disposed at both ends of the connecting rod 111. One end of the connecting rod 111 is detachably fixed to the first end plate 112 to allow adjustment of the length of the connecting rod 111 between the first end plate 112 and the second end plate 113. The other end of the connecting rod 111 is fixed to the second end plate 113. In this embodiment, the end of the connecting rod 111 that is detachably fixed to the first end plate 112 is threaded, the first end plate 112 is a nut, and the other end of the connecting rod 111 is welded to the second end plate 113.

[0039] like Figure 1-3 、 Figure 5-7 As shown, two folded edges 121 extending toward each other are provided on both sides of the open end of the channel steel 12. A plurality of elastic plates 13 are provided inside the groove of the folded edges 121. The plurality of elastic plates 13 are arranged along the height direction of the channel steel 12. The upper end of each elastic plate 13 is fixed to the channel steel 12, and the lower end of the elastic plate 13 is away from the channel steel 12 so that the elastic plate 13 is naturally inclined downward. The elastic plate 13 can be attached to the folded edges 121 under the action of external force. The elastic plate 13 is a steel plate with a thickness range of 5mm-8mm.

[0040] like Figure 1 As shown, the width of the first end plate 112 and the second end plate 113 is greater than the distance between the folded edges 121 and smaller than the width of the channel steel 12, so that the first end plate 112 and the second end plate 113 can enter the channel steel 12 and cannot be detached from the channel steel 12.

[0041] like Figure 5-7 As shown, when the connector 11 is placed downward from the top of the shear wall into the two channel steels 12 and contacts the elastic plate 13, the connector 11 applies external force to the elastic plate 13, so that the elastic plate 13 fits with the folded edge 121 and fills the gap between the connector 11 and the folded edge 121.

[0042] Because the elastic plate 13 only needs to be arranged in the channel steel 12 on one side to ensure that the connecting rod 111 is in a tensioned state, in this embodiment, the elastic plate 13 is arranged in the channel steel 12 where the first end plate 112 is located, and fills the gap between the first end plate 112 and the folded edge 121.

[0043] like Figure 7 As shown, the multiple connecting members 11 are perpendicular to the operating rod 4 and arranged along the extension direction of the operating rod 4. The operating rod 4 connects the multiple connecting members 11 together to form a whole. The spacing between the multiple connecting members 11 is consistent with the spacing between the multiple elastic plates 13 in the first opening groove 21. During installation, by pressing the operating rod 4, multiple connecting members 11 can be installed simultaneously at the same vertical position, which is simple and quick to operate.

[0044] like Figure 1 、 Figure 5-7 As shown, the length of the connecting rod 111 is greater than the distance between the opposite surfaces of the first wall form 2 and the second wall form 3 and less than the distance between the bottom of the first opening groove 21 and the bottom of the corresponding second opening groove 31 .

[0045] Concrete is poured into the cavity between the first wall formwork 2 and the second wall formwork 3 to form a concrete layer, and the connecting structure 1 is located in the concrete layer.

[0046] Installation steps:

[0047] S1: First, fix the operating rod 4 and all the connecting parts 11 to be installed vertically at the same position.

[0048] S2: Adjust the positions of the first end plates 112 on all the connecting members 11 on the connecting rods 111 so that the connecting members 11 can be inserted into the channel steels 12 and can press the corresponding elastic plates 13 .

[0049] S3: Press the operating rod 4 hard so that the first end plate 112 can press the corresponding elastic plate 13 to reach a specified height to complete the installation.

[0050] S4: pouring concrete in the cavity between the first wall form 2 and the second wall form 3 to complete the construction of the shear wall.
