[0001] The utility model relates to the technical field of wall connecting pieces, in particular to a pre-embedded detachable wall connecting piece. Background Art

[0002] In the field of construction technology, the fastener-type steel pipe scaffolding must use wall connecting parts, which plays a vital role in the stability of the scaffolding and directly affects the safety of the frame. The commonly used practice at present is to reserve short steel pipes in the four side beams of the wall of the main structure, and then use fasteners to tie the reserved short steel pipes with the scaffolding uprights and scaffolding crossbars and other external scaffolding.

[0003] The Chinese utility model patent with publication number CN211421810U, published on September 4, 2020, discloses a revolving external scaffolding wall connecting part, which belongs to the technical field of scaffolding components for construction, and can solve the problems of complex structure and high use cost of existing scaffolding connecting parts. It includes an L-shaped steel bar, the long arm section of the L-shaped steel bar passes through the wall, and the long arm section of the L-shaped steel bar is provided with an internal fixed steel plate and an external fixed steel plate, wherein the external fixed steel plate and the long arm section are welded and fixed, and a fastening bolt is provided on the outside of the inner fixed steel plate, and a connecting steel pipe is welded in parallel to the short arm section of the L-shaped steel bar, and the lower half of the connecting steel pipe is the connecting section, and the upper half is the welding section.

[0004] The above patent is easy to carry, easy to operate, detachable and can be used multiple times, but it requires the removal of the embedded steel pipes during the later wall construction and plastering process, and the repair of the holes left by the embedded steel pipes. The repair work is complicated and prone to water leakage and other safety hazards. Utility Model Content

[0014] 2. The utility model uses a method of connecting two pre-buried pipes in parallel and using connectors for reinforcement, which effectively avoids deformation and disturbance of the pre-buried pipes caused by concrete pouring and vibration.

[0015] 3. The utility model welds a locking ring on the wall connecting steel pipe, so that the wall connecting piece itself can be connected with the external scaffolding to form a whole, the overlap is flexible and reliable, and the construction time is saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 2As shown, the embedded detachable wall connecting part of this embodiment includes a steel pipe 1 and a base 2, the steel pipe 1 is fixed to the base 2, and also includes an embedded pipe 3, one end of the embedded pipe 3 extends to the inside of the wall 10, and the other end of the embedded pipe 3 passes through the base 2, the second bolt 9 is threadedly connected to the outer end of the embedded pipe 3 and abuts against one end of the base 2, and the other end of the base 2 abuts against the wall 10; a connecting part 4 is fixed between the multiple embedded pipes 3.

[0025] The connecting seat 5 is connected to the locking ring 6 through a hinged joint. Through the locking ring 6, the utility model can be flexibly overlapped with the external scaffolding system.

[0026] Furthermore, a plurality of ribs 8 are fixed between the steel pipe 1 and the base 2 .

[0027] Furthermore, the steel pipe 1 is fixed to the base 2 after being tilted downward.

[0028] Furthermore, the steel pipe 1 is inclined downward at an angle of ten degrees.

[0029] The steel pipe 1 is tilted downward by ten degrees to achieve the installation specification of the wall connection piece being higher inside and lower outside.

[0030] The method of using the utility model is:

[0031] The embedded pipe 3 is embedded in the wall 10 before the concrete wall 10 is poured. A plurality of embedded pipes 3 are connected by a connecting piece 4. While controlling the buried spacing of the embedded pipes 3, deformation and displacement of the embedded pipes 3 caused by vibration during concrete pouring are avoided, thereby affecting the installation of other components. The connecting seat 5 is connected to the locking ring 6 through a hinge joint. Through the locking ring 6, the utility model can be flexibly overlapped with the external scaffolding system.

[0032] After the wall connection piece is used, the base 2 and the steel pipe 1 are removed without removing the embedded pipe 3 in the wall 10, and no hole that needs to be repaired is left.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
