The inner side of the three thick steel plates 2 is attached to the concrete wall 1, thereby increasing the stability and tightness between the three thick steel plates 2 and the concrete wall 1. At the same time, the connection method of full welding is adopted between the multiple three thick steel plates 2 to form a whole, increasing the firmness of the three thick steel plates 2 during use. The upper side of the angle steel back rib 5 is rounded, which makes the upper side of the angle steel back rib 5 smoother when the waterproof coiled material is laid on the outer side of the angle steel back rib 5 during construction, and it is not easy to cause damage to the waterproof coiled material due to sharp corners. At the same time, the three thick steel plates 2 and the angle steel back ribs 5 can be applied to floor formwork.
