As a new type of scaffolding system developed in recent years, it is mainly used in high-rise and super-high-rise building structures. It can climb up or down along the building. This system has completely changed the scaffolding technology: first, there is no need to turn over the frame, and second, the disassembly and assembly process of the scaffolding is eliminated (it is used until the construction is completed after one assembly), and it is not limited by the height of the building, which greatly saves manpower and materials. And from the perspective of safety, it has also greatly improved the traditional scaffolding. It has great development advantages in high-rise buildings. As an important component for closing the gap between the frame and the building, the inner extension plate is usually welded with bent steel plates and angle irons. The inner extension plate made by this method is heavy, the production and processing process is complicated, and the steel inner extension plate is easy to rust. Paint needs to be sprayed to prevent rust caused by water ingress during stacking and use.
