Technical Field

[0001] The utility model relates to the technical field of composite plate type shear walls, in particular to a composite plate type shear wall connection structure. Background Art

[0002] The composite slab shear wall is formed by connecting two layers of prefabricated reinforced concrete slabs through steel trusses or connectors to form a wall panel component with a middle cavity. After prefabrication in the factory, there is a cavity between the slabs. After installation on site, concrete is poured in the cavity. The wall formed by prefabricated and cast-in-place concrete is a composite slab shear wall, commonly known as a "double-skin wall";

[0003] At present, the vertical connection method of composite plate shear wall mostly adopts extended steel bar connection, specifically, the steel bar is extended between the two walls, and the prefabricated connection piece is welded between the two steel bars. The problem in this process is that the construction process is complicated, and because the mold for making the wall panels is the same, the positions of the reserved stirrups between the two shear walls are the same, and collisions often occur during the construction process, which is not conducive to the standardization of construction and affects the construction quality;

[0004] Based on the above problems, there may already be technical means in the current technology to solve the above technical solutions. This case intends to provide an alternative or replacement technical means. Utility Model Content

[0006] Preferably, a reinforcing gasket is provided at the connection between the second bolt and the notch.

[0007] Preferably, a PE reinforcement block matching the vertical seam is sleeved on the outer side of the first bolt.

[0008] Preferably, the inner side of the reinforcement plate and the PE reinforcement block are filled with a building sealant layer.

[0009] Preferably, grooves corresponding to the first bolt nut and the second nut are respectively provided on the inner side of the connecting member.

[0010] Preferably, the connecting piece is configured as a U-shaped piece as a whole.

[0011] Beneficial Effects

[0012] The utility model provides a composite plate shear wall connection structure, which has the following beneficial effects: the technical solution sets a connecting piece between the first wall and the second wall, and through the threaded connection cooperation between the first bolt, the first nut, the second bolt and the second nut, the connecting piece can be firmly connected to the first wall and the second wall, and the connection strength between the first wall and the second wall is further increased by the reinforcement plate, the PE reinforcement block and the building sealant layer. Compared with the existing extended steel bar connection method, the overall operation of the technical solution is simple and the connection is stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example

[0019] See also Figure 1-3 , the utility model provides a technical solution: a composite plate type shear wall connection structure;

[0020] This case aims to provide a composite plate shear wall connection structure that is conducive to quick connection. The existing composite plate shear wall connection method is complicated to operate;

[0021] Based on the above problems, the components in this case include a first wall 1 and a second wall 2, a connecting piece 3 is provided between the first wall 1 and the second wall 2, first bolts 4 are inserted on both sides of the connecting piece 3, the first bolts 4 extend from the vertical gap between the first wall 1 and the second wall 2, a reinforcing plate 5 is provided on one side of the first wall 1 and the second wall 2, the first bolt 4 penetrates the reinforcing plate 5 and is threadedly connected with a first nut 6, notches are provided on the upper and lower sides of the reinforcing plate 5, second bolts 7 are provided at the notches, the second bolts 7 penetrate the first wall 1 and the connecting piece 3 respectively, and are threadedly connected with a second nut 8;

[0022] It should be noted that, during the construction process, the connector 3 is first inserted into the bottom of the first wall 1 and the top of the second wall 2. At this time, the PE reinforcement block 10 sleeved on the outside of the first bolt 4 is inserted into the vertical seam of the first wall 1 and the second wall 2, and then the reinforcement plate 5 is covered on the outside of the vertical seam. At this time, the first bolt 4 penetrates the reinforcement plate 5, and then is threadedly connected with the first bolt 4 through the first nut 6, completing the preliminary fixation of the reinforcement plate 5 and the connector 3;
