[0002] In prefabricated buildings, in order to achieve the thermal insulation effect of the wall, the application of prefabricated external wall panels (i.e. PCF panels) that integrate the insulation board and the outer wall is becoming more and more widespread. The PCF panels are assembled on the inner wall of the building to form a sandwich insulation wall. A problem that comes with this is that during the erection of the external scaffolding, how to pass through the PCF board to fix the external scaffolding on the inner wall has become a technical problem that needs to be solved in this field. The conventional practice in this field is to embed steel pipes on the inner wall. The disadvantage is that the embedded steel pipes have a large diameter and need to open a larger hole in the PCF board, which causes a large range of damage to the PCF board and affects the thermal insulation effect at the hole. On the other hand, the embedded steel pipes embedded in the inner wall cause a waste of materials, resulting in high construction costs, and the embedded steel pipes exposed outside the outer wall need to be cut, resulting in complicated construction procedures.

[0008] Furthermore, the utility model provides an external scaffolding wall connection system suitable for an external wall structure having a PCF board, wherein the end of the threaded sleeve is aligned with the outer surface of the inner wall.

[0009] Furthermore, the utility model provides an external scaffolding wall connection system suitable for an external wall structure having a PCF board, wherein the high-strength screw rod comprises a rod head and a rod body, and the rod body comprises a smooth rod and a threaded rod.

[0010] Furthermore, the utility model provides an external scaffolding wall connection system suitable for an external wall structure having a PCF board, wherein the single fastener is connected to the smooth rod of the high-strength screw and one end of the single fastener abuts against the inner side of the rod head of the high-strength screw.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board. A high-strength screw that passes through the PCF board and is threadedly connected to a threaded sleeve pre-buried in the inner wall is connected to a wall connection steel pipe that is parallel and close to the vertical pole of the external scaffold through a single fastener, thereby fixing the external scaffolding on the inner wall, so that the external scaffolding can be effectively tied to the inner wall, thereby improving the stability of the external scaffolding during use.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings: According to the following description, the advantages and features of the utility model will be more clearly understood. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0025] Please refer to Figures 1 to 4The embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board, comprising a threaded sleeve 1 pre-buried horizontally on an inner wall 6, a high-strength screw 2 threadedly connected to the threaded sleeve 1 through a PCF board 7, the high-strength screw 2 extending out of the outer side of the PCF board 7, and a wall connection steel pipe 4 horizontally connected to the vertical pole 81 on the inner side of the external scaffold 8 through a double fastener 3 at a horizontal position close to the high-strength screw 2, that is, the wall connection steel pipe 4 is close to and parallel to the high-strength screw 2, one end of the wall connection steel pipe 4 is pressed against the PCF board 7, and the other end extends outward from the vertical pole 81 on the inner side, and is connected by a single fastener 5 at the overlap of the high-strength screw 2 and the wall connection steel pipe 4. The external wall structure with a PCF board includes an inner wall 6 and a PCF board 7 connected thereto.

[0026] Please refer to Figure 1 to Figure 2 The embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board. The high-strength screw 2 that is threadedly connected to a threaded sleeve 1 embedded in the inner wall 6 passes through the PCF board 7 and is connected to a wall connection steel pipe 4 that is parallel and close to the vertical pole 81 of the external scaffolding 8 through a single fastener 5, thereby fixing the external scaffolding 8 on the inner wall 6, so that the external scaffolding 8 can be effectively tied to the inner wall 6, thereby improving the stability of the external scaffolding 8 during use.

[0027] Please refer to Figure 1 to Figure 2 The embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board. During the dismantling process of the external scaffolding 8, the high-strength screw 2 is rotated to be removed from the threaded sleeve 1, so that the high-strength screw 2 can be recycled and reused, which reduces the cost and difficulty of the dismantling process and has the effect of facilitating disassembly and assembly. It avoids the problem that the traditional pre-buried steel pipe is pre-buried on the inner wall 6, which leads to the need to cut and remove the pre-buried steel bars extending outside the PCF board 7 during the dismantling process, and the pre-buried steel pipe after cutting is too short to be used, resulting in material waste.

[0028] Please refer to Figure 1 to Figure 2 The embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board. The diameter of the high-strength screw 2 is much smaller than the diameter of the embedded steel pipe. Therefore, when passing through the PCF board 7, the opening size of the PCF board 7 is smaller, which reduces the damage range of the PCF board 7 and reduces the influence of the PCF board on the thermal insulation effect.

[0029] The embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board. The high-strength screw rod 2 is completely removed from the PCF board 7 for later plugging, and the problem of poor insulation effect at the node caused by the need to keep the embedded steel pipe passing through the PCF board 7 in the removal process in the traditional embedded steel pipe method will not occur. The PCF board 7 after plugging reduces the risk of water leakage.

[0030] Please refer to Figures 2 to 3 In order to improve the reliability of pre-embedded threaded sleeve 1 in inner wall 6, the embodiment of the utility model provides an external scaffolding wall connection system suitable for PCF board external wall structure, wherein the outer circumference of the threaded sleeve 1 is provided with outwardly protruding ribs 12 or pre-embedded studs. The pre-embedded effect can be improved by the ribs 12 or pre-embedded studs, and the figure only illustrates the case of ribs 12.

[0031] Please refer to Figures 1 to 3 In order to prevent the threaded sleeve 1 from being embedded in the inner wall 6 and causing the concrete to be blocked by the internal threaded hole of the threaded sleeve 1, the embodiment of the utility model is suitable for an external scaffolding wall connection system with a PCF board exterior wall structure, and the length of the internal threaded hole of the threaded sleeve 1 is less than the length of the threaded sleeve 1. That is, the threaded sleeve 1 has a solid part and an internal threaded hole part, and one end of the internal threaded hole part faces outward. When the threaded sleeve 1 is embedded, the high-strength screw 2 is connected thereto to prevent the concrete of the inner wall 6 from blocking the internal threaded hole. The length of the threaded sleeve 1 can be 120mm, the outer diameter can be 28mm, the diameter of the internal threaded hole can be 16mm, and the length of the internal threaded hole is 60mm. That is, the specification of the threaded sleeve 1 can be M16×120.

[0032] Please refer to Figure 1 to Figure 2 In order to further reduce costs and avoid the threaded sleeve 1 being retained in the PCF board 7 and affecting its thermal insulation performance, the embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board, and the end of the threaded sleeve 1 is aligned with the outer surface of the inner wall 6. This design enables the high-strength screw 2 to be completely removed from the PCF board 7, and the removal hole of the PCF board 7 is blocked later, avoiding the problem that the threaded sleeve 1, embedded steel pipes and other metal parts are retained in the PCF board 7 and affect its thermal insulation effect.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4In order to improve the reliability of the connection between the wall-connecting steel pipe 4 and the high-strength screw 2 through the single fastener 5, the embodiment of the utility model provides an external scaffolding wall connection system suitable for an external wall structure with a PCF board, wherein the high-strength screw 2 includes a rod head 21 and a rod body 22, and the rod body 22 includes a smooth rod 221 and a threaded rod 222. At this time, the single fastener 5 is connected to the smooth rod 221 of the high-strength screw 2 and one end of the single fastener 5 is against the inner side of the rod head 21 of the high-strength screw 2. The single fastener 5 is against the rod head 21 of the high-strength screw 2, which can improve the reliability of the connection between the single fastener 5 and the wall-connecting steel pipe 4 and prevent the single fastener 5 from slipping out of the high-strength screw 2. Moreover, the smooth rod 221 of the high-strength screw 2 is connected to the single fastener 5 at the overlapping part with the wall-connecting steel pipe 4, so as to avoid the problem that the threads on the threaded rod 222 are damaged when the threaded rod 222 is connected to the overlapping part with the wall-connecting steel pipe 4. The length of the rod body 22 can be 300 mm, and the length of the threaded rod 222 can be 60 mm. That is, the specification of the high-strength screw 2 is M16×120. The specifications and sizes of the high-strength screw 2 and the threaded sleeve 1 are not limited to the above specific sizes and can be adjusted as needed.

[0034] In order to facilitate the connection between the wall-connecting steel pipe 4 and the vertical pole 81 of the external scaffolding 8, the embodiment of the utility model provides an external scaffolding wall-connecting system suitable for an external wall structure with a PCF board, and the diameter of the wall-connecting steel pipe 4 is the same as the diameter of the vertical pole 81 of the external scaffolding 8.
