[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The height of the basement slab wall of the conventional island of the nuclear power project is about 14m. After the slab wall is constructed to 0m, the part of the slab wall below 0m needs to be waterproofed, and there is a lot of concrete replacement and backfilling work. In order to shorten the construction period, it is necessary to install cantilever scaffolding around the conventional island so that the floor construction above 0m and the waterproofing and backfilling work below 0m will not affect each other.

[0004] At present, there are two main forms of cantilever scaffolding in common use. One is to embed embedded parts in the concrete wall, and then weld supporting materials such as steel and channel steel to the embedded parts. The other form is to fix the embedded parts with tension screws on the concrete wall, and then weld supporting materials such as steel and channel steel to the embedded parts. The installation methods of these two methods are similar, and both require a large amount of high-altitude operations, low safety, and difficult installation and removal. The installation and removal workload is large, the construction efficiency is low, the construction period is long, and the construction cost is high. Utility Model Content

[0013] As a further technical solution, an oblique rod is arranged between the horizontal frame and the vertical frame.

[0014] As a further technical solution, the vertical frame includes a plurality of support rods, which are spaced and evenly distributed on one side of the transverse frame; each support rod is fixedly connected to the transverse frame, and diagonal rods are connected between the support rods and the transverse frame.

[0015] As a further technical solution, the cone is arranged horizontally, and an embedded plate is fixed to the end of the cone embedded in the concrete wall.
