[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figures 1-3 The preferred embodiments of this utility model will be described in further detail below:

[0020] like Figure 1 As shown, this utility model preferably describes a detachable scaffolding wall-connecting structure used on fair-faced concrete walls. It is installed at the tie bolt holes formed during the pouring stage of the structural wall 1. The structure includes pre-embedded bolts 2, tapered embedded parts 3, extension bolts 4, locking nuts 5, wall-attached steel plates 6, and wall-connecting rods 8. The pre-embedded bolts 2 are embedded inside the structural wall 1, and a tapered embedded part 3 is fixed to one end near the outer side of the structural wall 1. The tapered embedded part 3 includes a frustum-shaped embedded part body 301. A bolt hole 302 is opened at the axial position of the embedded part body 301, with the smaller end of the embedded part body 301 facing inward. The embedded part 301 is fixed to the pre-embedded screw rod 2 through the screw hole 302. The large end of the embedded part body 301 faces outward, and its large end face is flush with the outer surface of the structural wall 1. The large end is fixed to the extension screw rod 4 through the screw hole 302. The outer end of the extension screw rod 4 extends to the outer side of the structural wall 1. The wall-attached steel plate 6 and the locking nut 5 are sequentially sleeved on its body. The inner side of the wall-attached steel plate 6 is attached to the structural wall 1 and is pressed and fixed by the locking nut 5. The wall-connecting rod 8 is vertically fixed on the wall-attached steel plate 6, and its outer end extends to the scaffold and is connected and fixed to the scaffold.

[0021] Since the fair-faced concrete wall surface project has high requirements on the forming effect of the outer surface of the structural wall, in order to reduce the number of openings on the structural wall 1, the scaffold wall connecting structure is arranged at the tensioning screw hole formed during the pouring stage of the structural wall 1, the tensioning assembly adopts a three-section screw rod form, the adjacent two sections of screw rods are connected by a tapered embedded part 3, after pouring and demolding, the middle embedded screw rod 2 and the tapered embedded parts 3 on both sides are reserved, the threads on the middle embedded screw rod 2 can be matched with the screw holes 302 of the tapered embedded parts 3 to realize detachable fixing, and on the other hand, the holding force with the structural wall 1 can be improved to ensure the stability of the scaffold wall after the scaffold wall;

[0022] In order to avoid damage to the surface of the structural wall 1, a flexible gasket 7 made of rubber is further sleeved on the lengthening screw 4 between the wall connecting steel plate 6 and the structural wall 1, the flexible gasket 7 and the wall connecting steel plate 6 can avoid the situation that the lengthening screw 4 shakes in the hole when the wall connecting structure is subjected to external force, can effectively increase the stress surface, and plays a fixing role, and at the same time, damage to the surface of the structural wall 1 around the hole is prevented;

[0023] In order to ensure the stability of the wall connecting structure, the locking nut 5 needs to tightly press the wall connecting steel plate 6 and the flexible gasket 7 on the structural wall 1, and after the completion of the scaffold construction, the wall connecting structure also needs to be removed by loosening the locking nut 5, therefore, the locking nut 5 not only needs to have sufficient locking capacity, but also needs to have the characteristics of convenient installation and removal, for the above purpose, the locking nut 5 is preferably in the form of a hill-shaped nut, and of course, in order to make the wall connecting structure more firm, a double-nut form can be adopted to lock the wall connecting steel plate 6;

[0024] After the completion of the mission of the scaffold wall connecting structure, the tapered embedded part 3, the lengthening screw 4, the locking nut 5, the wall connecting steel plate 6 and the wall connecting rod 8 need to be removed and recycled, at this time, in order to facilitate the recycling of the tapered embedded part 3 and make it easier to be screwed out of the structural wall 1, a dismounting groove 304 is formed on the end face of the large end of the embedded part body 301, and the specific form of the dismounting groove 304 can be set according to the form of the matched dismounting wrench, for example, it can be set in the form of a general internal hexagonal groove;

[0025] To ensure the reliable connection of the tapered embedded part 3 with the embedded screw rod 2 and the tapered embedded part 3 with the lengthening screw rod 4, it is necessary to ensure that the embedded screw rod 2 and the lengthening screw rod 4 both have sufficient lap length with the tapered embedded part 3, so that under the premise that the model of the tapered embedded part 3 is fixed and the hole length of the screw hole 302 is fixed, the lap length of any one of the embedded screw rod 2 and the lengthening screw rod 4 with the tapered embedded part 3 is too long, which will cause the instability of the whole system stress, therefore, it is appropriate to set a partition rib 303 in the screw hole 302 of the embedded part body 301, the partition rib 303 divides the screw hole 302 into two coaxial parts (the two parts can be connected or not connected, and the diameters of the two parts can be the same or different, as long as the partition rib 303 can separate the two parts and block the screw rod to avoid the screw rod from exceeding the partition rib 303 when being set), the lengths of the two parts are matched with the lap lengths required by the embedded screw rod 2 or the lengthening screw rod 4, of course, the above function can also be realized by the diameter size, for example, the diameter of the part corresponding to the embedded screw rod 2 is larger than the diameter of the part corresponding to the lengthening screw rod 4, and when the embedded screw rod 2 is installed first and the end abuts the position where the diameter of the screw hole 302 changes, it will naturally appear that it cannot continue to be screwed in.

[0026] The specific construction steps of the utility model are as follows:

[0027] Step one, after the wooden I-beam system template is removed, the part of the screw rod is pulled out, and the original tapered embedded part 3 is reserved at the position where the wall connecting piece is needed without hole plugging;

[0028] Step two, the lengthening screw rod 4 is reconnected at the corresponding tapered embedded part 3, and the lengthening screw rod 4 is connected and fixed with the embedded screw rod embedded in the wall through the tapered embedded part 3;

[0029] Step three, the flexible gasket 7, the wall-attached steel plate 4 and the locking nut 5 are installed in sequence at the lengthening screw rod 4, and the locking nut 5 is tightened and fixed;

[0030] Step four, the wall connecting rod 8 is fixed with the scaffold to realize the scaffold wall connecting operation;

[0031] Step five, after the scaffold completes the mission, the scaffold and the wall connecting structure are removed;

[0032] Step six, the tapered embedded part 3 is screwed out from the structural wall 1 by a matched wrench, and the hole plugging is completed.

[0033] The utility model discloses when installing the template, advance burying conical embedded part 3 and pre -buried screw rod 2, and after removing the template, install the wall connecting piece and only need to connect the lengthening screw rod 4 and can be tightened with lock nut 5, borrow the hole of installing the template, need not to punch again. The utility model has the following beneficial effects: the lengthening screw rod 4 is connected into the wall body through the conical embedded part 3, and is consistent with the surrounding bolt hole, does not affect the hole blocking and finish construction of later period, reduces the influence that the wall body appearance may exist consistency deviation in hole blocking construction, in addition to pre -buried screw rod 2, the utility model wall connecting piece can be recycled and repeatedly used, and through the turnover of each item, can create good economic benefits.

[0034] The above only is the preferred embodiment of the utility model, and does not use to limit the utility model, and any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
