[0025] See also Figure 1-3 The present embodiment provides a scaffolding free pre-embedded quick-disassembly wall connection component, including a sleeve, a bolt 2, a steel pipe 3 and a connection unit 4. The sleeve is pre-embedded in the wall column template, the bolt 2 is threadedly connected to the sleeve, the connection unit 4 is detachably connected to the bolt 2, the steel pipe 3 is detachably connected to the connection unit 4, and the connection unit 4 is used to determine the relative position of the steel pipe 3 and the wall column template. In this solution, the sleeve is pre-embedded in the wall column template, the sleeve is threadedly connected to the bolt 2, and then the connection unit 4 is detachably connected to the bolt 2 and the steel pipe 3 respectively. After the wall connection component is completed, the bolt 2 is directly removed to complete the removal of the steel pipe 3 and the connection unit 4 from the wall Compared with the existing wall ties, the disassembly on the column formwork requires cutting of the steel pipe 3 embedded in the wall column formwork after the construction is completed. The construction method of the wall ties in this scheme will not cause waste of the steel pipe 3 and can be recycled. It solves the problem that the existing wall ties include steel pipe 3, which needs to be inserted into the wall column formwork in advance, and then concrete is injected into the wall column formwork. After the wall ties are completed, one end of the steel pipe 3 is embedded in the concrete and cannot be taken out. Therefore, when dismantling, it is necessary to cut the steel pipe 3 extending out of the concrete. Such a construction method will cause great waste of the steel pipe 3, which is not conducive to material saving and environmental protection.

[0026] Further, the connection unit 4 of the present solution includes an upper fastening member 401 and a lower fastening member 402, the upper fastening member 401 is provided with a circular groove, the bolt 2 is coaxially connected to the circular groove, the upper fastening member 401 and the lower fastening member 402 are mutually fastened to form a matching groove that matches the steel pipe 3, the steel pipe 3 is coaxially connected to the matching groove, and the upper fastening member 401 is provided with a circular groove to realize the connection between the upper fastening member 401 and the bolt 2; and when the upper fastening member 401 and the lower fastening member 402 are mutually fastened, The two form a matching groove, which cooperates with the steel pipe 3 to realize the connection between the upper fastening part 401 and the lower fastening part 402 and the steel pipe 3, thereby realizing the matching connection between the bolt 2, the upper and lower fastening parts 402 and the steel pipe 3. It is worth mentioning that in order to ensure the connection stability between the bolt 2 and the upper fastening part 401, the circular groove of this scheme is provided with a thread, and the circular groove and the bolt 2 are connected by a thread, which further enhances the connection stability between the bolt 2 and the upper fastening part 401.

[0027] Specifically, the two ends of the upper fastening member 401 and the lower fastening member 402 of the present solution are respectively connected by a screw rod 1 to enhance the connection stability between the upper fastening member 401 and the lower fastening member 402 .

[0028] Furthermore, in order to solve the positioning problem between the steel pipe 3 of this solution and the upper fastening member 401 and the lower fastening member 402, one end surface of the steel pipe 3 of this solution is arranged to fit the side wall surface of the wall column formwork.

[0029] Furthermore, the bolt 2 of the present solution includes a coaxially connected nut 201 and a stud 202, the stud 202 is connected to the circular groove by threads, and the cross-sectional shape of the nut 201 is a regular polygonal structure. In addition, the connection unit 4 of the present solution also includes two sliding members 403 and a sliding bolt 404, the two sliding members 403 are symmetrically slidably arranged at the two ends of the upper buckle 401, the side walls of the two sliding members 403 are matched with the side walls of the nut 201, the two sliding members 403 are both provided with slots, and the sliding bolt 404 locks the distance between the two sliding members 403 by passing through the slots of the two sliding members 403. The purpose of such a setting of the present solution is that, due to vibration during the construction process, the bolt 2 will release its connection with the sleeve and the upper buckle due to vibration. The connection between the upper and lower parts 401 is based on this, and based on this, the present solution needs to set a limited position structure to limit the movement of the bolt 2. Based on this, the present solution is provided with two sliding parts 403, and the two sliding parts 403 are slidably and symmetrically arranged at the two ends of the upper buckle part 401. After the side walls of the two sliding parts 403 are respectively pressed against the side walls of the nut 201, the two sliding parts 403 are fixed by the sliding bolt 404, and the distance between the two sliding parts 403 is locked, so that the two sliding parts 403 are set in abutment with the nut 201, and the rotation of the nut 201 is limited. In order to ensure the fit effect of the two sliding parts 403 and the nut 201, the cross-sectional shape of the nut 201 is a regular polygon. Such a setting enables the side wall surface of the nut 201 and the side wall surface of the sliding part 403 to be set in abutment with each other. It is worth noting that in order to ensure that the nut 201 can be adjusted by rotation so that its side wall surface fits with the side wall surface of the sliding member 403, a gap is left between the nut 201 and the wall column template in this solution to facilitate the rotation of the bolt 2.
