[0002] In practical engineering, the following situation is often encountered: when the masonry wall is high (such as a factory wall height of 6-10m), scaffolding needs to be erected for wall masonry and plastering operations. The traditional method is to pre-drill holes during wall construction and use scaffolding pipes to hold the wall in place with ring beams or structural columns. This method is time-consuming and labor-intensive, affecting the construction progress. Therefore, there is an urgent need to develop a new type of wall tie to solve the above-mentioned technical problems. Utility Model Content

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Reference Figures 1 to 6 This embodiment provides a rear-mounted flower basket wall-connecting component, including a fastener 1, a flower basket sleeve 2, a hexagonal double-ended screw 3, and an expansion tube 4; the fastener 1 includes a fastener body 1-1, on which a connecting screw 1-2 is provided, the connecting screw 1-2 is threaded to one end of the flower basket sleeve 2, the other end of the flower basket sleeve 2 is threaded to one end of the hexagonal double-ended screw 3, and the other end of the hexagonal double-ended screw 3 is connected to the expansion tube 4.

[0031] In this embodiment, the fastener body 1-1 includes a connecting seat 1-11, one end of which is hinged to a clamping member 1-12, and the other end of which is fitted with a screw 1-13. The screw 1-13 can be assembled and connected with the clamping member 1-12 and tightened and fixed by a washer and a nut.

[0032] In this embodiment, the connecting seat 1-11 has an arc groove in the middle to facilitate assembly and connection with the circular scaffold upright. A groove (not shown in the figure) is provided at the center of the arc groove, and a hole for installing the connecting screw 1-2 is opened in the groove. When the connecting screw 1-2 passes through the hole, the head of the connecting screw 1-2 is located in the groove. The connecting screw 1-2 is welded to the connecting seat 1-11.

[0033] In this embodiment, the clamping member 1-12 is arc-shaped, and the end of the clamping member 1-12 is provided with a connecting part, and the connecting part is provided with an opening groove for installing the screw 1-13.

[0034] In this embodiment, the two ends of the basket sleeve 2 are provided with connecting threads of opposite directions. One end is a forward connecting thread, which is threaded to the hexagonal double-ended screw 3, and the other end is a reverse connecting thread, which is threaded to the connecting screw 1-2 (correspondingly, the connecting screw 1-2 also has a reverse connecting thread). By rotating the basket sleeve 2 clockwise or counterclockwise, the distance between the connecting screw 1-2 and the hexagonal double-ended screw 3 can be adjusted.

[0035] In this embodiment, the hexagonal double-ended screw 3 includes a screw body, and a hexagonal nut is fixed in the middle of the screw body for easy construction. The connecting threads on the screw body on both sides of the hexagonal nut have the same direction of rotation. One end is connected to the basket sleeve 2, and the other end is connected to the expansion tube 4.

[0036] In this embodiment, the hexagonal nut is welded to the screw body. Of course, the hexagonal nut and the screw body can also be an integrally formed structure.

[0037] In this embodiment, the expansion tube 4 includes an expansion tube body 4-1 and an expansion head 4-2. The expansion tube body 4-1 has expansion grooves 4-3 evenly distributed along the circumference, and a limiting hole 4-4 is opened at the position corresponding to the expansion grooves 4-3. The expansion head 4-2 has a threaded hole for connecting with the hexagonal double-ended screw 3 inside. The expansion head 4-2 is tapered, and the small end has a limiting protrusion 4-5 evenly distributed along the circumference, corresponding to the limiting hole 4-4. When the expansion head 4-2 is assembled in the expansion tube body 4-1, the limiting protrusion 4-5 is located in the limiting hole 4-4. During use, the hexagonal double-ended screw 3 is installed inside the expansion head 4-2. A hole is drilled inside the concrete structure, and the expansion tube 4 is placed in the drilled hole. The hexagonal double-ended screw 3 is turned clockwise. Since the expansion head 4-2 cannot rotate, the hexagonal double-ended screw 3 moves inward and close to the concrete structure until it is blocked and cannot move laterally. When the hexagonal double-ended screw 3 is continued to rotate, the expansion head 4-2 can only move outward because it cannot rotate. That is, the expansion head 4-2 moves into the expansion tube body 4-1, causing the expansion tube body 4-1 to expand and thus be fixed in the concrete structure.

[0038] In this embodiment, the expansion groove 4-3 is straight, which facilitates the movement of the expansion head 4-2 into the expansion tube body 4-1, thereby achieving a better expansion effect.

[0039] In this embodiment, the limiting hole 4-4 is arrow-shaped, and its function is to restrict the expansion head 4-2 from rotating, but it can move into the expansion tube body 4-1.

[0040] In this embodiment, the limiting protrusion 4-5 is arc-shaped and is integrally formed with the expansion head 4-2.

[0041] In this embodiment, the diameter of the connecting screw 1-2 on the fastener body 1-1 is 12mm and the length is 100mm; the length of the basket sleeve 2 is 200mm; the diameter of the screw body of the hexagonal double-ended screw 3 is 12mm and the length is 200mm; the total length after assembly is 400mm (part of the screw extends into the basket sleeve).

[0042] The specific implementation process of this embodiment:

[0043] During installation, first, attach the expansion tube body 4-1 to one end of the hexagonal double-ended screw 3, and simultaneously screw the externally conical expansion head 4-2 onto the hexagonal double-ended screw 3. Then, assemble it with the connecting screw 1-2 on the basket sleeve 2 and the fastener body 1-1 of the fastener 1 to form a whole. Make a small hole in the existing concrete structure 6, insert one end of the component with the expansion tube 4 into the small hole, and fasten the other end to the scaffold upright 5 with the fastener 1. Then, turn the hexagonal double-ended screw 3 clockwise. The conical expansion head 4-2 in the hole moves outward and squeezes the expansion tube body 4-1 to generate expansion and fixation, finally achieving a reliable connection between the scaffold and the concrete structure 6.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
