How to support the 3d assembled reinforced truss floor?

The 3d assembled reinforced truss floor is fixed at the bottom of the reinforced truss, and the floor is overlapped with the floor. Due to the thin thickness of the floor slab (only 0.5mm), reliable temporary supports should be set in the middle of the span before concrete construction. The existing supporting structure is steel pipe scaffold, and the installation foundation of steel pipe scaffold needs to be set on the lower foundation. However, after the lower concrete pouring is completed, it is necessary to wait for a certain period of time to reach the important strength of installing steel pipe scaffolding. During the waiting period, the floor slab often deflects and sinks, resulting in cracks at the joint, which will leak slurry in the later concrete construction, affecting the impression and quality of the floor slab.
