The hollow box type slab bridge is manufactured to a certain length.

That is, the hollow box-type girders are sequentially manufactured according to the outer and inner formwork having a length corresponding to 1 (ONE) segment.

After manufacturing the hollow box-type slab bridge having a length corresponding to one segment, the outer formwork 40 and the inner formwork 60 were moved in the longitudinal direction (longitudinal direction) of the bridge and again having a length corresponding to one segment. The bridge is completed while continuously manufacturing the hollow box-type slab bridge, wherein the outer formwork 40 and the inner formwork 60 to be reused are commonly referred to as system formwork 80.

Such a system formwork 80 is installed between the form steel members constituting the formwork body called a wale 82 and the outer formwork at the work site as shown in FIG. 1B to support and move the outer formwork in the formwork.
