During construction, workers generally embed U-shaped round steel anchor rings in the concrete. After the concrete reaches the required strength, the cantilever beam of the unloading platform is directly inserted into the anchor ring. Then, wooden wedges are used to wedge into the gap between the anchor ring and the cantilever beam as the main reinforcement method, forming a platform that can carry a certain number of formworks, wooden squares, steel pipes, and fasteners, which is convenient for the transfer of materials between floors on site.
