[0031] The utility model provides a wall fastener 100, which is used for a scaffold wall fastener 1000.

[0032] See also Figure 1 In one embodiment of the utility model, the wall fastener 100 includes a pad 110, a buckle 120 and a positioning structure 130. The pad 110 is used to be fixedly connected to the wall. The positioning structure 130 includes an axis groove 132 and a convex shaft 131 limitedly inserted into the axis groove 132. One of the axis groove 132 and the convex shaft 131 is formed on the pad 110, and the other is formed on the buckle 120. The convex shaft 131 and the axis groove 132 cooperate to enable the pad 110 and the buckle 120 to be rotatably connected.

[0033] The technical solution of the utility model is to provide a positioning structure 130 between the buckle 120 and the pad 110, so that the buckle 120 and the pad 110 can be connected and relatively rotated under the action of the convex shaft 131 and the shaft groove 132, so that the buckle 120 can adjust the buckle groove position according to the position direction of the external frame upright when installed with the scaffolding, which is convenient for the staff to install on site, not only improving the installation efficiency of the scaffolding wall connecting piece 1000 and the scaffolding, but also improving its adaptability.

[0034] In order to prevent the buckle 120 from detaching from the pad 110 during actual use, in one embodiment of the utility model, the convex shaft 131 includes a connecting column 1311 and an anti-detachment head 1312 connected to the connecting column 1311, one end of the connecting column 1311 is connected to the pad 110 or the buckle 120, and the other end of the connecting column is connected to the anti-detachment head 1312, and the cross-sectional area of ​​the anti-detachment head 1312 is larger than the cross-sectional area of ​​the connecting column; the groove wall of the shaft groove 132 is adapted to the outer side wall of the convex shaft 131. Since the cross-sectional area of ​​the anti-slip head 1312 is larger than that of the connecting column, a more secure connection can be provided, reducing the risk of the buckle 120 falling off. However, it should be noted that for easy installation, the cross-sectional area of ​​the anti-slip head 1312 cannot be much larger than the cross-sectional area of ​​the connecting column 1311, and the material of the anti-slip head 1312 should be designed to be a material that can undergo a certain elastic deformation, such as rubber or silicone material, so that the anti-slip head 1312 is not easy to fall out of the shaft groove 132 after being inserted into the shaft groove 132 of the corresponding shape.

[0035] Furthermore, in an embodiment of the present invention, the cross-sectional area of ​​the connecting column 1311 is gradually increased from the end away from the anti-slip head 1312 to the end close to the anti-slip head 1312. By gradually increasing the cross-sectional area of ​​the connecting column 1311, the load can be effectively distributed, stress concentration can be reduced, and the bearing capacity of the structure can be improved. This design can make the structure more stable when subjected to external force or vibration, and also helps to reduce fatigue damage of the material.

[0036] Of course, the anti-slip function can also be achieved directly by optimizing the structure of the convex shaft 131. Specifically, in one embodiment of the utility model, the cross-sectional area of ​​the convex shaft 131 is gradually increased from the end away from the bottom of the shaft groove 132 to the end close to the bottom of the shaft groove 132. On the one hand, by gradually increasing the cross-sectional area of ​​the connecting column 1311, the load can be effectively distributed, stress concentration can be reduced, and the bearing capacity of the structure can be improved. This design can make the structure more stable when subjected to external force or vibration, and also helps to reduce fatigue damage of the material; on the other hand, because the groove wall of the shaft groove 132 is adapted to the outer wall of the convex shaft 131, after the convex shaft 131 is inserted into the shaft groove 132, the cross-sectional area of ​​the larger end of the convex shaft 131 is larger than the area of ​​the notch of the shaft groove 132, so that the convex shaft 131 is not easy to slip out of the shaft groove 132.

[0037] In one embodiment of the utility model, the buckle 120 includes a base 121, a clamping arm 122 and an adjusting member 123. A first clamping slot is formed on one side of the base 121, so that the first end of the clamping arm 122 is rotatably mounted on the base 121. A second clamping slot is formed on one side of the clamping arm 122. The first clamping slot and the second clamping slot are used to clamp the outer frame pole of the scaffolding together; the adjusting member 123 is used to adjust the clamping size of the first clamping slot and the second clamping slot. In this way, the buckle 120 can adapt to poles of different diameters or sizes, thereby achieving flexible installation and use, improving installation efficiency and connection reliability, and facilitating maintenance and replacement of parts. In actual use, it is necessary to ensure that the design of the adjusting member 123 is reasonable, easy to operate, and the clamping force can meet the use requirements of the scaffolding.

[0038] Furthermore, in an embodiment of the present invention, the buckle 120 also includes a rotating pin 124, and the clamping arm 122 is rotatably connected to the seat body 121 through the rotating pin 124; through the rotating pin 124, the clamping arm 122 can rotate on the seat body 121 to achieve a wider range of angle adjustment and adaptability.

[0039] Furthermore, the adjusting member 123 includes an adjusting bolt 123a, which passes through the second end of the clamping arm 122 and is inserted and locked on the seat body 121 to limit the movable position of the clamping arm 122 on the seat body 121. By adjusting the adjusting bolt 123a, it can be ensured that the clamping arm 122 maintains the correct position during installation to avoid the situation where the clamping force is insufficient. This helps to improve the stability and reliability of the connection and ensure the safety of the scaffold. In actual use, it is necessary to carefully adjust the adjusting bolt 123a to ensure that the range of motion of the clamping arm 122 meets the safety requirements.

[0040] See also Figure 2 The utility model also provides a scaffold wall connecting member 1000, which includes the wall connecting fastener 100 as described above. The specific structure of the wall connecting fastener 100 refers to the above embodiment. Since the scaffold wall connecting member 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0041] Generally, the traditional embedded parts 200 are embedded in the cast-in-place beams of the structure using steel pipes, and connected with the external frame uprights to form a whole. However, after the external frame is removed, the embedded steel pipes need to be cut, and the steel pipes can only be wasted as disposable materials; in addition, after the steel pipes are cut, holes will be left on the cast-in-place beams of the structure, which need to be repaired, which is labor-intensive and not conducive to the waterproof quality of the structure itself after the repair. To solve the above problems, in one embodiment of the utility model, the scaffolding wall connecting part 1000 also includes an embedded part 200 and at least one threaded fastener 300. The embedded part 200 is used to be arranged in the wall, and the embedded part 200 is formed with at least one threaded hole; the threaded fastener 300 passes through the pad 110 and is inserted and locked in the threaded hole to fix the pad 110 against the wall. During the actual installation, the specific operation steps are as follows: reserve the embedded parts 200 in the cast-in-place structural beam and fix the position. After the concrete reaches the strength, the pad 110 is connected and locked with the embedded parts 200 by threaded fasteners 300 (such as bolts or screws, etc.), and then the pad 110 and the buckle 120 are connected by the convex shaft 131 and the shaft groove 132 to form a whole. Finally, the buckle 120 is fixedly connected with the external frame upright to achieve the function of the wall connecting part. In this way, in the subsequent disassembly process, there is no need to arrange cutting, which greatly reduces the waste of steel pipes, and there is no need to fill the holes that need to be repaired after the embedded steel pipes are cut. After the scaffolding is dismantled, the wall fastener 100 can be removed, recovered and recycled.

[0042] Furthermore, in order to ensure the reliability of the fixation between the embedded part 200 and the backing plate 110, in one embodiment of the utility model, the embedded part 200 includes an embedded connecting plate 220 and two embedded sleeves 210, the two embedded sleeves 210 are arranged at intervals at both ends of the embedded connecting plate 220, and the embedded sleeves 210 are formed with threaded holes; the scaffolding wall connecting part 1000 includes two threaded fasteners 300, and the two threaded fasteners 300 are respectively locked in the two embedded sleeves 210. In this way, the setting of the embedded part 200 can provide more support and fixation. Of course, in other embodiments, more than two embedded sleeves 210 and threaded fasteners 300 corresponding to the number of embedded sleeves 210 can also be provided to further improve the connection stability.

[0043] Furthermore, in an embodiment of the present invention, the embedded sleeve 210 is a K-plate nut. This design can provide a better threaded connection effect, ensuring that the connection between the scaffolding wall connecting member 1000 and the embedded connecting plate 220 is firm and reliable. The K-plate nut usually has a large load-bearing capacity and tensile strength, and is suitable for connection parts that need to withstand large tensile forces. In addition, the design of the K-plate nut can also improve installation efficiency and simplify the construction process.

[0044] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
