[0031] like Figures 1 to 6As shown, the embodiment provides a connecting structure of building wall plate, which comprises at least two groups of spaced composite shear wall plates a, the composite shear wall plate a is provided with embedded horizontal ribs a3 arranged in upper and lower spaces, and the two ends of the embedded horizontal ribs a3 extend to the left and right sides outside the composite shear wall plate a. The embedded horizontal ribs a3 of adjacent composite shear wall plates a are connected by a plurality of connecting pieces b. The connecting piece b comprises two connecting blocks b1 arranged in mirror image, the connecting block b1 is provided with a plurality of through holes b2 corresponding to the number of embedded horizontal ribs a3, the inner side of the through hole b2 is communicated with a circular truncated cone groove b3, and an anchor clamping piece b4 is matched and arranged in the circular truncated cone groove b3, and the anchor clamping piece b4 is sleeved on the embedded horizontal rib a3. It also includes a clamping unit for centering and tensioning the two connecting blocks b1.

[0032] In the design, the two embedded horizontal ribs a3 are connected by the connecting piece b, so as to realize the connection of the two adjacent composite shear wall plates a. The two connecting blocks b1 in the connecting piece b are centered and clamped by the clamping unit. In the process of centering and clamping, the circular truncated cone groove b3 in the connecting block b1 is embedded with the anchor clamping piece b4, so that the anchor clamping piece b4 is further compressed. The compression effect makes the anchor clamping piece b4 clamp the embedded horizontal rib a3, improves the friction between the two, improves the safety and reliability of the connection of the two composite shear wall plates a, and realizes the firm and stable connection between the two composite shear wall plates a.

[0033] In some embodiments, the clamping unit comprises a through hole b5 opened on the two connecting blocks b1, a threaded rod b6 penetrating through the two through holes b5 and diverging to the outside of the two through holes b5, and a nut b7 threadedly connected at both ends of the threaded rod b6. By rotating the two nuts b7, the two connecting blocks b1 are moved to the center, so as to adjust the distance between the two connecting blocks b1, further lock the anchor clamping piece b4, and make it clamp the embedded horizontal rib a3.

[0034] In some embodiments, the embedded horizontal ribs a3 on the composite shear wall plate a are arranged in two rows; correspondingly, the through hole b2, the circular truncated cone groove b3 and the anchor clamping piece b4 in each connecting block b1 are arranged in two groups. The through hole b5, the threaded rod b6 and the nut b7 are arranged between the two through holes b2. The design realizes the integral connection of the horizontal row of embedded horizontal ribs a3 by the two connecting blocks b1, improves the tensile strength; the threaded rod b6 is arranged in the middle of the connecting block b1, which ensures the balance of both sides, helps to evenly distribute the stress on the connecting block b1, and also provides stability when the connecting block b1 moves to the center.

[0035] In some embodiments, the outer side of the perforation b2 is rounded, which greatly improves the convenience of embedding the horizontal rib a3 into the perforation b2, and the rounded edge smoothes the entrance edge, so that the embedded horizontal rib a3 can be more smoothly aligned and passed through the perforation b2. It is worth noting that in the present application, the inner side is close to the middle position of the two superimposed shear wall plates a, and the outer side is away from the middle position of the two superimposed shear wall plates a.

[0036] As shown in Figure 2 In the present embodiment, two steel cages c are arranged between the two superimposed shear wall plates a, and the two steel cages c are located on both sides of the connecting piece b. The concrete between the two steel cages c connects the adjacent superimposed shear wall plates a. This design mainly enhances the connection strength and integrity between the superimposed shear wall plates a, and improves the stability and carrying capacity of the structure. The provision of the steel cage c provides additional support and reinforcement, which helps to disperse and bear external loads, and jointly resist deformation and damage. In addition, this connection method also helps to improve the seismic performance of the structure, ensuring safety and reliability under extreme conditions such as earthquakes.

[0037] In some embodiments, the superimposed shear wall plate a includes two corresponding split wall plates a1, and the connecting plate a2 is fixed between the split wall plates a1, the connecting plate a2 is arranged in a horizontal staggered manner, and the connecting plate a2 is arranged in a horizontal staggered manner. The opposite split wall plates a1 abut, and a plurality of groups of round holes are formed on the connecting plate a2, and the embedded horizontal rib a3 penetrates through the round hole. The connecting plate a2 is fixed by the embedded horizontal rib a3, so as to further realize the positioning of the two split wall plates a1, and the concrete is poured between the two split wall plates a1 to form the superimposed shear wall plate a. This design can enhance the stability and integrity of the superimposed shear wall plate a, improve its carrying capacity and seismic performance, and the combination of the connecting plate a2 and the embedded horizontal rib a3 ensures that the wall can uniformly distribute stress when subjected to external load, reducing deformation and crack generation. This structure is also convenient for construction and installation, improving construction efficiency.

[0038] Further, the diameter of the round hole is greater than the diameter of the embedded horizontal rib a3. This design ensures that the concrete slurry can flow smoothly from the round hole on the connecting plate a2 when pouring concrete, thereby facilitating the flow of slurry between the cavities. This flowability not only helps to ensure the uniformity and compactness of the concrete filling, but also increases the tightness of the connection between the two split wall plates a1, improving the overall stability and carrying capacity of the structure.

[0039] The construction steps of the present application are as follows:

[0040] Step one: precast composite shear wall plate a, two split wall plate a1 corresponding arrangement, using embedded horizontal muscle a3 through all connecting plate a2, so that two split wall plate a1 connected, then set formwork, between the formwork and split wall plate a1 pouring concrete, forming a composite shear wall plate a, and make embedded horizontal muscle a3 exposed with composite shear wall plate a both sides;

[0041] Step two: two composite shear wall plate a set to the design position, the connecting block b1 relative to the threaded rod b6 into the formation Figure 4 The structure is placed between the embedded horizontal muscle a3; then two connecting block b1 and anchor clip b4 in order to wear into the corresponding embedded horizontal muscle a3, the formation Figure 5 The structure; by screwing the nut b7 to achieve two connecting block b1 center clamping, in the process, two connecting block b1 gradually compresses the anchor clip b4 so that it clamps embedded horizontal muscle a3, the two embedded horizontal muscle a3 is connected.

[0042] The structure design makes two composite shear wall plate a in to both sides, can produce a significant pull. Under the action of the pull, the anchor clip b4 will further clamp embedded horizontal muscle a3, and embedded horizontal muscle a3 between the larger friction, thereby enhancing the stability of the connection between two composite shear wall plate a, significantly improve the tensile capacity of the structure.

[0043] Step three: in two composite shear wall plate a between the layout of fixed reinforcement cage c, then set the outer formwork, between the outer formwork and two composite shear wall plate a pouring concrete.
