The reinforcement is aligned with the mounting hole of the iron sheet and the reinforcement hole of the U-shaped template, and is connected and fixed by fastening bolts.

[0009] Preferably, the reinforcement piece is used to reinforce the formwork system, and the reinforcement piece is selected to have different lengths according to the width of the U-shaped formwork to ensure that both sides can press the corner module side rib bevel formwork.

[0010] Preferably, the anti-fall EA is used to connect the internal formwork system and the external wooden board of the small space.

[0011] Preferably: positioning angle plates are welded at both ends of the corner module, and lifting channel steels are provided at the top of the corner module and the U-shaped template. The lifting channel steels are fixedly connected by fastening bolts through the positioning angle plates welded at the top of the corner module and the reinforcing ribs welded on the inner side of the U-shaped template.

[0012] A method for operating a small space formwork system, comprising the following steps:
