The screw jack contracting step contracts the screw jack 31 and separates it from the floor slab 1 in a state in which the hydraulic jack 32 is supported by the floor slab 1. At this time, the inner mold and the truss frame 40 are supported by the hydraulic jack 32 only.

The hydraulic jack retracting step retracts the hydraulic jack 32, which has been inflated in the jack inflation stage, so that the roller 33 is coupled to the upper side of the rail 34.

At this time, the roller 33 and the rail 34 can slide.

The cylinder expansion step includes a side wall die 10 installed inside the upper slab 2 which is formed by expanding the hydraulic cylinder 35 for movement with the coupling part 36 fixed to the rail 34 as a support shaft, The inner mold 20 and the truss frame 40 are moved through the sliding of the roller 33 and the rail 34. [

Then, the engaging portion disassembling step disassembles the engaging portion 36 coupled to the rail 34. [

In the cylinder contracting step, the expanded moving hydraulic cylinder 35 is contracted to move the engaging portion 36.

At this time, as the other side of the movable hydraulic cylinder 35 is contracted with the reference axis, the engaging portion 36 is moved. The side wall formwork 10 and the hatch formwork 20 installed inside the upper slab 2 constructed according to the engagement of the rail 34 of the joint portion 36 and the expansion or contraction of the hydraulic cylinder 35 for movement The inner mold) and the truss frame 40 are integrally moved to the next construction site.
