DETAILED DESCRIPTION

[0025] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0026] Reference Figure 1 This embodiment provides a prefabricated shear wall sleeve-free connection structure, including a shear wall body 1 and a first embedded part 2. A mounting groove 11 is provided in the middle of the side end surface of the body 1, and planes are provided at the ends of the body 1 on both sides of the mounting groove 11 to facilitate later alignment and pouring. One end of the first embedded part 2 is fixedly connected to the inside of the body 1, and the other end of the first embedded part 2 is provided with a connecting ring 20, which is located in the mounting groove 11. The body 1 is a hardened concrete or reinforced concrete structure.

[0027] Reference Figure 1 and 2 The first embedded part 2 includes a sleeve 21 and a screw-on part 22. The sleeve 21 is a straight cylindrical structure. The outer surface of the sleeve 21 is fixedly connected to the main body 1 (for example, by pre-embedded fixed connection), and the inner surface of the sleeve 21 is connected to the screw-on part 22 by threads. The inner surface of the sleeve 21 is provided with an internal thread, and the outer surface of the screw-on part 22 is provided with an external thread. The internal thread and the external thread are meshed with each other to achieve fine adjustment of the extension length of the screw-on part 22 to ensure convenient construction.

[0028] Reference Figure 2The utility model further includes a second embedded part 3, which is in a straight plate structure; the second embedded part 3 is provided with a first through hole 31, which is sleeved with the outer surface of the sleeve 21. The end of the sleeve 21 away from the rotating part 22 is fixedly connected with an abutment plate 211 (for example, connected by integral molding), and the abutment plate 211 and the rotating part 22 are respectively arranged on both sides of the second embedded part 3. The abutment plate 211 fits with the second embedded part 3, so that the second embedded part 3 can transmit resistance to the abutment plate 211, so that the second embedded part 3 can assist the first embedded part 2 in bearing force, thereby improving the structural stability of the utility model.

[0029] Reference Figure 2 The utility model also includes a third embedded part 4, which is an L-shaped rod structure; the third embedded part 4 includes a first pull-connecting rod 41 and a second pull-connecting rod 42 that are vertically fixed to each other (for example, connected by bending and integrally forming), and the length direction of the first pull-connecting rod 41 is arranged parallel to the axial direction of the first embedded part 2; the second embedded part 3 is provided with a second through hole 32, and the first pull-connecting rod 41 is plugged into the second through hole 32.

[0030] Reference Figure 2 The length direction of the second tie rod 42 is perpendicular to the axial direction of the first embedded part 2, and the second tie rod 42 points in a direction away from the first embedded part 2, so that the total side projection area of ​​the first embedded part 2, the second embedded part 3 and the third embedded part 4 is increased, thereby improving the pulling force transmitted from the main body 1 to the first embedded part 2 through the second tie rod 42.

[0031] Reference Figure 2 The second embedded part 3 is provided with a load-bearing protrusion 33, and the load-bearing protrusion 33 abuts against the side wall of the second tie rod 42. Since the first tie rod 41 and the second tie rod 42 are formed by bending, there must be a rounded corner at the connection position of the first tie rod 41 and the second tie rod 42. Therefore, the side of the second tie rod 42 cannot be directly fitted with the second embedded part 3, causing the rounded corner to abut against the sharp corner position of the end of the second through hole 32 and form a situation of concentrated force. Therefore, the load-bearing protrusion 33 is provided to enable the load-bearing protrusion 33 to transmit force between the second embedded part 3 and the second tie rod 42, thereby improving the stability and service life of the utility model.

[0032] Reference Figure 2 The first connecting rod 41 is located on the side of the abutting plate 211 , and a protrusion is provided on the surface of the first connecting rod 41 to increase the friction between the main body 1 and the first connecting rod 41 , thereby improving the force transmission effect from the main body 1 to the third embedded part 4 .

[0033] Reference Figure 3 and 4 The adjacent edges of two adjacent shear walls are close to each other so that the adjacent connecting rings 20 are located on the same axis, and then the connecting rod 5 is used to penetrate the two connecting rings 20 to achieve connection.

[0034] Reference Figure 6 The second embedded part 3 is circular; the bearing protrusion 33 is located at the edge of the second embedded part 3; the bearing protrusion 33 is located on the side of the second embedded part 3 away from the abutment plate 211. There are three second through holes 32; the three second through holes 32 are arranged in an equiangular circular array. There are three third embedded parts 4, and the three third embedded parts 4 are arranged in the three second through holes 32 to improve the uniformity and stability of force transmission.

[0035] The second embedded part 3 is provided with a reinforcement hole 34, through which the main bodies 1 on both sides of the second embedded part 3 can be connected to increase the connection strength of the main bodies 1 on both sides of the second embedded part 3. A plurality of reinforcement holes 34 are provided and arranged in an equiangular circular array inside the load-bearing protrusion 33 to improve uniformity.

[0036] The mounting groove 11 is trapezoidal or V-shaped to fit the installation of the screw-on component 22 .

[0037] Installation steps: ① Place several shear walls upright so that the ends of adjacent shear walls are close to each other and the connecting rings 20 of adjacent shear walls are in a coaxial state; ② Intersperse the connecting rod 5 and the connecting ring 20; ③ Install the formwork 6 on both sides of the end of the shear wall; ④ Pour concrete in the installation groove 11, and remove the formwork 6 after the concrete is cured.

[0038] The utility model utilizes adjacent connecting rings 20 as fulcrums to achieve the connection of the shear wall, avoiding the use of traditional sleeves, having a simple structure, convenient installation, and improved construction efficiency; at the same time, the utility model utilizes the second embedded part 3 and the third embedded part 4 to enhance the pulling force of the main body 1 on the first embedded part 2, thereby enhancing the structural stability and improving the engineering quality.
