[0029] Example 1

[0030] See also Figure 1-Figure 3 In this embodiment, the disassembly-free formwork includes an exterior wall panel 10 and an interior wall panel 20. The exterior wall panel 10 is provided with an embedded bolt 11, and adjacent embedded bolts 11 on adjacent exterior wall panels 10 are provided with connecting pieces 12. The interior wall panel 20 is provided with connecting bolts 21 corresponding to the embedded bolts 11, and a connecting sleeve 22 for tightening the connecting piece 12 is screwed between the connecting bolt 21 and the embedded bolt 11.

[0031] In this embodiment, the rapid splicing of adjacent exterior wall panels 10 is achieved through the cooperation of the connecting piece 12 and the embedded bolt 11, and the rapid splicing of the exterior wall panels 10 and the interior wall panels 20 is achieved through the cooperation of the connecting sleeve 22, the connecting bolt 21 and the embedded bolt 11. After the casting is completed, the exterior wall panels 10 form the exterior wall surface, and the interior wall panels 20 form the interior wall surface, which simplifies the construction process.

[0032] It should be noted that the embedded bolts 11 are arranged at the corners of the exterior wall panel 10, and the embedded bolts 11 are arranged vertically with the exterior wall panel 10. As an example, the exterior wall panel 10 is a tile, and the embedded bolts 11 are back bolt screws. A back bolt hole is punched on the back of the tile with a back bolt drill bit through a punching machine, and the back bolt screw is connected to the back bolt hole.

[0033] In addition, the connecting member 12 is constructed as a rectangular plate as a whole, and through holes 14 for the embedded bolts 11 to pass through are opened at the four corners of the connecting member 12. Each through hole 14 corresponds to the embedded bolt 11 at the corner of the exterior wall panel 10. After the embedded bolt 11 passes through the through hole 14, the connecting member 12 is fixed to the exterior wall panel 10 by using the connecting sleeve 22 screwed on the embedded bolt 11, and the connecting member 12 is arranged parallel to the exterior wall panel 10. By utilizing the cooperation between the connecting member 12 and the embedded bolt 11, one connecting member 12 can splice four exterior wall panels 10 into an integrated structure, thereby improving the splicing effect of the exterior wall panel 10.

[0034] In addition, the inner wall panel 20 is arranged parallel to the outer wall panel 10 as a whole, and a connecting bolt 21 that corresponds one to one with the embedded bolt 11 is passed through the inner wall panel 20. As an example, a countersunk hole for passing the connecting bolt 21 is opened on the inner wall panel 20 to prevent the bolt head of the connecting bolt 21 from extending to the outside of the inner wall panel 20. The connecting bolt 21 is fixed with a nut after passing through the aforementioned countersunk hole. The connecting bolt 21 and the inner wall panel 20 are arranged vertically, and the connecting bolt 21 and the embedded bolt 11 are arranged coaxially. The connecting sleeve 22 is screwed onto the outside of the embedded bolt 11 and the connecting bolt 21. The threaded connection between the connecting sleeve 22, the embedded bolt 11 and the connecting bolt 21 is coordinated to make the inner wall panel 20 and the outer wall panel 10 connected as an integrated structure.

[0035] It should also be noted that when the connection between the exterior wall panel 10 and the interior wall panel 20 is completed, the wall is cast. At this time, the embedded bolts 11, connectors 12, positioning nuts 13, connecting bolts 21 and connecting sleeves 22 are all cast inside the wall. The pull rod structure formed by the embedded bolts 11, connecting bolts 21 and connecting sleeves 22 can enhance the stability of the overall structure of the exterior wall panel 10 and the interior wall panel 20. After the wall is cast, the exterior wall panel 10 forms the exterior wall surface of the wall, and the interior wall panel 20 forms the interior wall surface of the wall, which simplifies the traditional wall construction process and effectively improves construction efficiency.

[0036] It should be understood that in order to improve the thermal insulation effect of the exterior wall, an insulation board is bonded to the inner wall of the exterior wall panel 10, and space for installing connecting parts is reserved on the insulation board; in order to avoid the distance between the exterior wall panel 10 and the interior wall panel 20 from changing due to the rotation of the connecting sleeve 22, a positioning nut 13 is also screwed on the connecting bolt 21, and the positioning nut 13 is tightly attached to the connecting sleeve 22.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
