The sides of this platform can be folded, which greatly reduces the transportation thickness of the platform, so that multiple platforms can be stacked for transportation. Since the sides of the platform can be folded, the main load-bearing capacity of the platform falls on the bottom plate. For this reason, it is necessary to increase the load-bearing capacity of the bottom plate, and at the same time, ensure that the bottom plate does not deform during the production process to ensure that the folding construction platform can be used safely after unfolding. Summary of the invention
