[0002] In modern construction, the construction of shear walls is mainly divided into prefabricated solid shear walls and composite slab shear walls. The main difficulty in the construction of composite slab shear walls is how to connect the wall panels. At present, the connection of composite slab shear walls mainly adopts the method of prefabricated components combined with concrete pouring.

[0003] At present, the prefabricated components of the composite slab shear wall are mainly vertical steel parts. During the connection process of the composite slab shear wall, they are often only connected to the steel bars connecting the shear wall panels. This results in limited connection force between the vertical steel bars and the shear wall panels on both sides during application, which is prone to cracking of the shear wall surface due to internal concrete stress and other problems. In view of this, in-depth research was conducted on the above-mentioned problems, which led to the creation of this case. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: in the application process of modern composite plate shear walls, the vertical connection between walls often adopts a single vertical steel bar to connect with the wall, while the composite plates on the other two sides have limited contact and limited bonding, which reduces the bearing capacity of the shear wall.

[0022] In response to the above problems, according to the instructions attached Figure 1-3 It can be seen that the present application discloses a composite plate shear wall connection structure, the composite plate shear wall is mainly composed of a first composite plate 1 and a second composite plate 2, the first composite plate 1 and the second composite plate 2 are arranged in parallel, the first composite plate 1 and the second composite plate 2 are connected by a matrix steel bar 3, the ends of the matrix steel bar 3 are respectively buried in the first composite plate 1 and the second composite plate 2, a connection structure is provided in the gap between the first composite plate 1 and the second composite plate 2, the upper and lower double-layer shear walls are guided and connected by the connection structure, and after installation, concrete is poured in the gap between the first composite plate 1 and the second composite plate 2 of the double-layer shear wall to form an integral shear wall;

[0023] According to the instruction manual Figure 1-3 It can be seen that the above connection structure includes at least one pair of vertical steel bars 4 arranged in a linear array, and the upper and lower ends of the vertical steel bars 4 are provided with connecting members 5 perpendicular to the first composite plate 1 and the second composite plate 2, and the two ends of the connecting member 5 are threadedly connected with a pair of telescopic rods 6;

[0024] In the specific implementation process, the two sides of the vertical steel bar 4 are attached to the relative wall surfaces of the first composite plate 1 and the second composite plate 2, so that the vertical steel bar 4 is in contact with and fused with the inner wall surfaces of the first composite plate 1 and the second composite plate 2 during casting to form a first connection structure, and at the same time, a connector 5 is respectively provided at the bottom and top ends of the vertical steel bar 4, a pair of telescopic rods 6 are threadedly connected to the connector 5, the telescopic rods 6 are movably connected to the connector 5 and partially embedded in the connector 5, and a plurality of pairs of reinforcing rods 7 are embedded in the first composite plate 1 and the second composite plate 2, and the number and position of the reinforcing rods 7 correspond to the telescopic rods 6 respectively;

[0025] The telescopic rod 6 and the connecting piece 5 are connected by threads.

[0026] As a preferred solution, further, the vertical steel bars 4 are oblong structural steel bars, and a pair of reinforcing rods 8 are symmetrically welded on both inner sides of the vertical steel bars 4.

The pair of reinforcing rods 8 play a limiting role. After being inserted into the first composite plate 1 and the second composite plate 2, they are limited by the reinforcing rods 8.
