[0003] Wall ties play an important role in strengthening the overall stability of the scaffolding, improving its stable bearing capacity and avoiding major accidents such as tipping or collapse.

[0004] For example, Chinese patent CN203097263U discloses a standardized revolving scaffolding wall connection component, including bolts, steel pipes and external frame uprights, PVC sleeves are installed on the bolts, first steel plates and second steel plates are installed on the bolts at both ends of the PVC sleeves, nuts are installed on the bolts on the outside of the first steel plate and the second steel plate, one end of the steel pipe is welded to the first steel plate, and the external frame uprights are installed on the steel pipe via fasteners.

[0005] There are relatively large gaps between the bolts and the inner wall of the steel pipe in the wall connection member. Thus, when the steel pipe is under pressure, the connection with the first steel plate may not be strong enough, and weld cracking may easily occur, thereby reducing the overall stability and resulting in reduced safety.

[0006] Therefore, corresponding improvements are made to the shortcomings of the wall connecting member. Utility Model Content

[0009] One end of the hollow screw is threadedly connected to the threaded hole, and the other end thereof passes through the sleeve and is threadedly connected to a fastening nut;

[0010] It also includes a fixing nut and a filling column, wherein the fixing nut is fixedly connected to one end of the hollow screw away from the steel pipe, the fixing nut is internally threaded with a solid screw, and one end of the solid screw extends into the steel pipe;

[0011] The filling column is provided with interconnected large through holes and small through holes, and the small through holes match the solid screw rod, so that the filling column and the solid screw rod are welded;

[0012] The large through hole is adapted to the hollow screw, and the outer surface of the filling column contacts the inner wall of the steel pipe.

[0013] Preferably, a gasket is provided between the fastening nut and the sleeve.

[0014] Preferably, one end of the solid screw away from the filling column is fixedly connected to a rotating head, and a circular hole is provided in the rotating head.

[0015] Preferably, one end of the steel pipe away from the fixing ring is connected and fixed to the outer frame pole through a pipe fastener.

[0016] Preferably, the gasket is circular or square.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the solid screw to rotate forward by rotating the rotating head. During the rotation process, the solid screw drives the filling column to rotate and move, and enters the gap between the hollow screw and the steel pipe to fill the gap between the hollow screw and the steel pipe, carry and support the steel pipe, closely fit, increase the contact area, avoid cracking of the weld between the steel pipe and the fixing ring during repeated use, and ensure the stability and safety of the wall connection during use.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] See also Figure 1-4 The utility model provides a technical solution for a turnover type standardized scaffolding wall connecting member:

[0027] Embodiment 1:

[0028] according to Figure 1-4 As shown, it includes a hollow screw 31, a steel pipe 21 and a sleeve 1 pre-buried in the shear wall. A fixing ring 22 is welded to one open end of the steel pipe 21, and a threaded hole is opened at the center of the fixing ring 22.

[0029] One end of the hollow screw 31 is threadedly connected to the threaded hole, and the hollow screw 31 is connected to the fixing ring 22. The other end of the hollow screw 31 passes through the sleeve 1 and is threadedly connected to the fastening nut 32. A gasket 33 is arranged between the fastening nut 32 and the sleeve 1. The gasket 33 is round or square. The hollow screw 31 is fixed to the shear wall through the cooperation of the fixing ring 22, the gasket 33 and the fastening nut 32.

[0030] It also includes a fixing nut 41 and a filling column 44. The fixing nut 41 is fixedly connected to the end of the hollow screw 31 away from the steel pipe 21. The fixing nut 41 is internally threaded with a solid screw 42. One end of the solid screw 42 extends into the steel pipe 21. The end of the solid screw 42 away from the filling column 44 is fixedly connected to a rotating head 43. A circular hole is opened in the rotating head 43, and the rod structure can be extended into the circular hole to drive the rotating head 43 to rotate.

[0031] The filling column 44 is provided with interconnected large through holes and small through holes, and the small through holes match the solid screw rod 42 , so that the filling column 44 and the solid screw rod 42 are welded to ensure that the filling column 44 and the solid screw rod 42 are tightly fitted.

[0032] The large through hole is adapted to the hollow screw 31, and the outer surface of the filling column 44 contacts the inner wall of the steel pipe 21, filling the gap between the hollow screw 31 and the steel pipe 21, bearing and supporting the steel pipe 21, tightly fitting and increasing the contact area, avoiding cracking of the weld between the steel pipe 21 and the fixing ring 22 during repeated use, thereby ensuring the stability and safety of the wall connection during use.
