DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 As shown, the present embodiment discloses a reusable external wall steel pipe scaffolding wall connection member tensioning device, including a tensioning screw rod 1 with an external thread, an inner limit nut 2, an outer limit nut 3 and a short section pipe section 4 are threadedly connected to the tensioning screw rod 1, an inner gasket 5 and an outer gasket 6 are respectively arranged on the sides corresponding to each other of the inner limit nut 2 and the outer limit nut 3, and the inner gasket 5 and the outer gasket 6 are both sleeved on the tensioning screw rod 1.

[0019] The short-joint pipe section 4 includes a short-joint pipe body 401, in which a threaded sleeve 402 is arranged, the threaded sleeve 402 is threadedly connected to the tension screw 1, and a plurality of connecting rods 403 are arranged in the gap between the threaded sleeve 402 and the short-joint pipe body 401, and the two ends of the connecting rod 403 are respectively welded to the short-joint pipe body 401 and the threaded sleeve 402.

[0020] In this embodiment, both ends of the outer wall of the short-joint tube body 401 are provided with retaining rings 404 , and the retaining rings 404 can prevent the short-joint tube section 4 from escaping from the cross fastener 8 .

[0021] In this embodiment, a locking nut 7 is provided at one end of the short pipe section 4 , the locking nut 7 is threadedly connected to the tension screw 1 , and the locking nut 7 abuts against the threaded sleeve 402 .

[0022] In this embodiment, there are two inner limit nuts 2 and two outer limit nuts 3, and the double nut structure can effectively prevent the nuts from loosening.

[0023] In this embodiment, through holes 101 are provided at both ends of the tension screw rods 1. When the wall anchor is not in use, the iron wire is passed through the through holes 101 on the tension screw rods 1 in sequence and then tied, so that the tension screw rods 1 can be easily collected.

[0024] like Figure 3 As shown, the use process of the utility model is as follows:

[0025] When in use, the holes naturally left when the shear wall is supported should be used as the insertion and pulling screws 1 as much as possible. When the position of the holes on the shear wall is inconsistent with the step distance of the scaffolding 9, drilling holes on the shear wall can be used.

[0026] First, insert the tension screw 1 into the hole of the shear wall, rotate the inner limit nuts 2 and the outer limit nuts 3 on both sides to make the inner gasket 5 and the outer gasket 6 close to the shear wall 10, and then rotate the short section pipe segment 4 along the tension screw 1 according to the distance between the scaffolding 9 and the wall, so that the short section pipe segment 4 is in a suitable position, and the short section pipe segment 4 is connected to the scaffolding 9 through the cross fastener 8.

[0027] The cross fastener 8 is also called a right-angle fastener, and its structure belongs to the prior art, and its use method is not described in detail.

[0028] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
