After completion of the movement of the bogie 20 and the steel foam 30 into the slab space S2 after the slab is constructed by the movement operation, the bridges 200 are constructed while repeating the ascending operation, the descending operation and the moving operation .

At this time, even if the first actuator 40 supporting the steel foam 30 is rotated, the steel foam 30 is held on the transverse frame 21a of the car 20.

The bridge construction structure 100 is characterized in that the bridge 20 moves along the rail 10 and can be used repeatedly for construction so that a separate slab formwork is unnecessary and the bridge 200 can be continuously constructed.

In addition, the bridging structure 100 can be used repeatedly semi-permanently by using the steel foam 30, so that the concrete curing quality can be maintained constant.

The bridging structure 100 uses the steel foam 30 to prevent the permeation of salt from the seawater during concrete curing and does not cause deformation, so that durability is excellent and durability is increased.

In addition, there is a problem that it is inconvenient for a worker to remove the slab formwork manually by completing the curing of the slab concrete after individually installing the slab formworks for each construction area, The construction 100 can easily move the steel foam 30 to the slab space S2 while moving the bogie 20 and the demolding operation after the curing of the concrete is automated so that the work is easy and simple.

In addition, when the concrete is cured, there is a risk of a safety accident such as a fall because the worker has to dismantle the slab form individually when the concrete is cured. In order to demolish the slab form, The bridging structure 100 of the present invention has a problem that the demolition work is quick and simple because of removing only the bogie 20 and the steel foam 30 performing the molding function for slab construction Safe and low cost is greatly reduced.
