The sole plate 110 is disposed on the lower side of the upper structure 1 so as to be adjacent to the upper side, and is made of a metal material such as an iron plate or the like.

The sole plate 110 is firmly coupled to the upper structure 1 on the upper side to support the upper structure 1 and coupled to the lower side 200 on the lower side.

The lower soles plate 120 is arranged to be adjacent to each of both side surfaces of the upper structure 1 and is disposed so as to be in contact with the upper surface of the lower soles plate 110 and has the same material as the lower soles plate 110 .

The bottom sole plate 110 and the side sole plate 120 are arranged such that a predetermined space is formed between the top structure 1 and the side sole plate 120, as shown in Figs.

The lower sol plate 110 and the side sol plate 120 and the upper structure 1 are coupled to each other by allowing the sealing material 130 to be described later to be injected through the space.

At this time, the bottom sole plate 110 and the side sole plate 120 may be welded to each other to be firmly coupled to each other.

The bottom sol plate 110 and the side sol plate 120 are coupled to the top structure 1 by a plurality of through holes 121 formed in the side sol plate 120 and a plurality of through holes 121 corresponding to the through holes 121.
