However, in the positions of large-span frame structures and cantilever structures such as balconies, the adjacent spacing of vertical vertical components is large, and the attachment interval of the guide rail cannot meet the specification and construction requirements. If the guide rail is attached to the outer cantilever beam, the guide rail interval may not meet the specification, which may cause the instability or overload of the scaffold body, and the stability of the scaffold cannot be guaranteed, and there is a probability of affecting the safety of the structure, and the subsequent maintenance cost is high.

[0028] See Figure 1 and Figure 2 The guide support heightening component 10 has a right-angled trapezoidal cage structure, forming a stable trapezoidal force system to distribute the vertical load and lateral bending moment transmitted by the scaffolding. The guide support heightening component 10 includes a top frame and a bottom frame. The size of the top frame is smaller than that of the bottom frame. A supporting steel plate 11 is welded on the top frame. A vertical square tube 14 and a first inclined steel tube 15 located at the side are connected between the top frame and the bottom frame. A second inclined steel tube 16 located inside the top frame is connected diagonally. A first reinforcing steel plate 17 is also welded at the connection between the bottom square tube 13, the first inclined steel tube 15 and the second inclined steel tube 16 to prevent stress concentration at the joint.

[0029] The base frame consists of four interconnected bottom square tubes 13, forming a stable foundation that fits snugly against the building structure. The top frame consists of four interconnected top square tubes 12. The design of reinforcing steel plates and diagonal steel tubes enhances the overall structural strength, improves the stability of the large-span frame structure and cantilever structure, and reduces safety risks.

[0030] In one embodiment, the top square tube 12 has a length of 420 mm, the bottom square tube 13 has a length of 600 mm, the supporting steel plate 11 has a thickness of 5 mm, and the vertical square tube 14 has a height of 600-900 mm; the diameter of the square tube is 30 x 30 mm, and the wall thickness is 3 mm.

[0032] Each circular hole 26 is connected to the scaffolding 3 by a bolt lock 30.

Here, the bolts 30 consist of bolts 32 passing through the top frame of the circular tube cantilever beam 20 and the guide seat extension 10. A pressure plate 33 and a nut 31 are installed on the lower side of the top frame, and a pressure plate 33 and a nut 31 are installed on the upper side of the circular tube cantilever beam 20.

[0041] The bolt-locking connection method effectively reduces the number of concrete pre-embedding construction steps and simplifies the construction process. The fixed connection between the kit and the internal structure allows for quick installation and ensures the stability of the guide rail.

[0042] The reinforcing steel plates and multiple diagonal steel pipes in the design enhance the overall structural strength of the scaffolding system, making it particularly suitable for large-span frame structures and cantilevered structures such as balconies. Compared to traditional methods, this technical solution significantly improves the stability of the scaffolding system and reduces safety risks caused by structural instability.

[0043] It is applicable to construction projects of different types and scales, especially for complex structures in high-rise and super high-rise buildings, providing a more flexible and reliable solution.

[0044] The mounting kit is easy to install and remove, and can be reused multiple times, reducing equipment and material waste on the construction site, improving work efficiency, and reducing subsequent maintenance costs.

[0045] By using fixed components, scaffold instability caused by the use of cantilever beams can be avoided, thereby reducing structural safety hazards. Its stability not only ensures construction safety but also guarantees the quality of the entire project.

[0046] The design of this mounting kit eliminates the need for extensive special pre-embedding and complex component construction during installation, thus reducing labor and material costs. Its reusability also significantly improves the cost-effectiveness of the equipment investment.
