[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A forming structure for climbing frame holes of precast wall panels includes a seamless steel pipe. The seamless steel pipe is in the form of "narrow at the bottom and wide at the top". A protection layer is coated on the surface of the seamless steel pipe. An internal thread for reverse punching and disassembly is arranged at the top of the seamless steel pipe, and an internal thread for direct punching and disassembly is arranged at the bottom of the seamless steel pipe.

[0006] As a preferred technical scheme of the utility model, internal threads are arranged inside the seamless steel pipe, and the model of the internal threads is M16.

[0007] As a preferred technical scheme of the utility model, the aperture of the lower end of the seamless steel pipe is 35mm, and the aperture of the upper end of the seamless steel pipe is 45mm.

[0008] As a preferred technical scheme of the utility model, the surface of the seamless steel pipe is sandblasted to form a protection layer.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The tooling has strong versatility: it can be applied to the forming production process requirements of both "direct punching" and "reverse punching" of precast wall panels for external frame / climbing frame holes;

[0011] A polyurethane forming protection device is adopted on the outside of the tooling rod, effectively improving the service life and turnover rate of the tooling, thereby reducing the loss rate during use and the input cost of production tooling;

[0012] When producing with this tooling, the formed appearance quality of the external frame / climbing frame holes of the precast wall panel is good whether it is "direct punching" or "reverse punching". It is fixed by welding at the base, and the positioning dimension is accurately controlled, thereby improving problems such as quality defects caused by uncontrollable factors during the product production process;

[0013] The tooling has strong applicability: This tooling can meet the forming of holes in the external scaffold / climbing scaffold for each project, improve the universality and turnover rate of the tooling among projects, and achieve the purpose of cost reduction and efficiency improvement in the operation of factory projects.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention;

[0020] Refer to Figures 1-3 , a structure for forming climbing scaffold holes in precast wall panels, includes a seamless steel pipe 2. The seamless steel pipe 2 is in the form of "narrow at the bottom and wide at the top". A protective layer 1 is coated on the surface of the seamless steel pipe 2. A reverse punching and disassembling internal thread hole 3 is arranged at the top of the seamless steel pipe 2, and a forward punching and disassembling internal thread hole 4 is arranged at the bottom of the seamless steel pipe 2.

[0021] An internal thread 5 is arranged inside the seamless steel pipe 2, and the model of the internal thread 5 is M16.

[0022] The aperture of the lower end of the seamless steel pipe 2 is 35 mm, and the aperture of the upper end of the seamless steel pipe 2 is 45 mm.

[0023] The surface of the seamless steel pipe 2 is sandblasted to form a protective layer 1, which is used to improve the overall service life of the tooling. Thanks to the sandblasting process, the visual quality of the tooling is improved, and at the same time, the wear rate during use is effectively reduced.

[0024] During the forward punching process: According to the deepening design drawing, lay out the positions of the external scaffold / climbing scaffold holes, and draw a "cross" mark at the corresponding positions;

[0025] Spot weld the positioning bolt cap to the mold table according to the position of the "cross" mark. After checking the dimensions, weld firmly;

[0026] Effectively limit and fix the "front casting" fixed base to the mold table through the positioning pin, and check the dimensions;

[0027] Insert the threaded end of the formwork for the "front and back" external frame / climbing frame tooling aluminum formwork into the base positioning pin device, and use the grout plugging bolt to screw into the reserved disassembly internal thread hole on the formwork during the "front casting" process, effectively preventing the slurry from entering the threaded hole and causing pollution and damage, and facilitating subsequent form removal operations.

[0028] During the reverse casting process:

[0029] Lay out the positions of the external frame / climbing frame holes according to the detailed design drawings, and draw a "cross" mark at the corresponding positions;

[0030] Spot weld the formwork base to the mold table according to the position of the "cross" mark. After checking the dimensions, weld firmly;

[0031] Turn the small end of the "front and back" external frame / climbing frame hole formwork downward. After connecting the internal thread 5 to the general purpose with a special fastening bolt, drive the internal thread 5 into the base through a pistol drill, and check and confirm the positioning dimensions and firmness;

[0032] After evenly applying the release agent to the surface of the formwork, carry out subsequent processes such as steel bar binding and embedded water and electricity, then carry out concrete placing and vibration. After the forming strength meets 15MPA, carry out form removal and disassembly.

[0033] This formwork has strong versatility: it can meet the production process requirements of the "front casting" and "reverse casting" of the external frame / climbing frame holes for precast wall panels;

[0034] The outside of the formwork rod is equipped with a polyurethane forming protection device, which effectively improves the service life and turnover rate of the formwork, thereby reducing the loss rate during use and the input cost of production formwork;

[0035] When using this formwork for production, whether it is "front casting" or "reverse casting" of the precast wall panel, the forming appearance quality of the external frame / climbing frame holes is good. Through welding and fixing of the base, the positioning dimensions are accurately controlled, thereby reducing quality defects caused by uncontrollable factors during the product production process;

[0036] This formwork has strong applicability: it can meet the forming use of the external frame / climbing frame holes in each project, improve the versatility and turnover rate of the formwork between projects, and achieve the purpose of cost reduction and efficiency improvement in the operation of the factory project.
