[0002] Structural "lowering" means "lowering the structural elevation of the floor or roof". Different rooms in a building have different functions and use different floor decoration materials - stone, floor tiles, wooden floors, terrazzo, fine stone, concrete, cement, etc. The construction methods of various materials are different, and the thickness is also different, which causes height differences between the floors of rooms with different materials. When the height difference is less than 30 mm, the thickness of the method can be adjusted with a cushion layer. If the height difference is greater than 30 mm, the "lowering" method is used to reduce the floor elevation on the side with a larger method thickness, so that the floors of different methods are basically flat after completion, avoiding too many small steps and small slopes to form obstacles and bring inconvenience to users.

[0003] When the slab structure is lowered at the construction site, the quality of the traditional hanging formwork is difficult to achieve. At the same time, the traditional hanging formwork system is prone to structural damage when the formwork is removed. Traditional structural lowering is mostly made of wooden beams, which have poor stability, and the molding effect cannot be guaranteed, and it is usually difficult to reuse them.

[0004] In summary, the existing technology has the problems of poor stability and flexibility, easy to cause unnecessary damage to the structure when demolding, cannot be reused, difficult to store, limited life span, waste of resources and inability to ensure molding quality.
