[0049] The end of the steel pipe 6 connected with the connecting mechanism 5 is provided with anti-skid lines or clamping grooves, so that the friction force with the clamping structure is enhanced.

[0050] The axis of the pre-embedded sleeve 2 is perpendicular to the surface of the main structure 1 or has a preset inclination to adapt to different construction scenes.

[0051] The fixing unit 4 serves to fix the pre-embedded sleeve 2. The end of the pre-embedded sleeve 2 adhering to the formwork is provided with four small holes, and the fixing unit 4 passes through the small holes and is nailed to the formwork surface. The fixing unit 4 is tightened by using an electric screwdriver to fix the pre-embedded sleeve 2 on the formwork surface.

[0052] The pre-embedded sleeve 2 is made of plastic material and has a hollow structure, through which a long bolt 3 passes. The end of the pre-embedded sleeve 2 is embedded in a nut 32 matched with the long bolt 3. The inner diameter of the pre-embedded sleeve 2 at the nut 32 is larger than that at the bolt body, forming a stepped inner surface. The end surface of the nut 32 is attached to the stepped surface, and the nut 32 cannot be displaced in the pre-embedded sleeve 2 under the constraint of the stress in the main structure 1. A small cover plate can be provided on the end surface of the pre-embedded sleeve 2 on the side of the nut 32 according to the application situation. After embedding the nut 32, the small cover plate is closed to seal the end surface, or transparent adhesive tape is wound to seal the end surface to prevent the nut 32 from being contaminated. After the end surface of the pre-embedded sleeve 2 close to the formwork is sealed by winding the transparent adhesive tape, the pre-embedded sleeve 2 is fixed to the formwork surface by the fixing unit 4 to prevent the cement mortar from entering the cavity of the pre-embedded sleeve 2.

[0054] The first perforation 511 of the connecting mechanism 5 is passed through by the long bolt 3, and the connecting mechanism 5 is hinged with the long bolt 3, so that the connecting mechanism 5 can rotate around the axis of the long bolt 3. The upper cover body 51 and the lower cover body 52 of the connecting mechanism 5 are hinged through the hinge shaft 53. The rotation of the upper cover body 51 and the lower cover body 52 around the hinge shaft 53 can realize the size of the second perforation 512. The second perforation 512 of the connecting mechanism 5 is passed through by the steel pipe 6.

The main structure 1 is poured with concrete, and the embedded sleeve 2 is firmly embedded in the concrete. After the concrete strength reaches a certain requirement, the installation of the wall connecting piece can be carried out.

[0056] The above describes one embodiment of the present application in detail, but the content is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application.
