The above-mentioned prior art is very troublesome because the vertical file of the pushed file is not uniform when the lower portion of the steel material is formed due to insufficient file hitting, so that it must be pushed and pulled by a hydraulic jack or the like. In addition, the installation process of the steel girder installed on the upper part of the steel lower vent is very unreasonable, and there are many uneconomical factors such as the operation time of the equipment is not efficient and the operation cost of the equipment is increased. Also, it is very uneconomical because the bridge structure can not be standardized or standardized, so it can not be reused repeatedly or the number of repeated reuse is small.

Therefore, it is required to develop a technique that can precisely and easily construct a file at the time of construction of a steel material bridge and has a high frequency of repeated use of the material.
