Steel frame structure using end connecting plate and cft column for unit modular house and the construction therefor

Bending one section tube form that can be poured inside the concrete to facilitate the connection of the poles making the correction of the unit structure of concrete-filled column and the unit structure of which is produced, and production and configure the effective cross section to not only be less expensive installation costs relates to a unit structure and the construction method, the units of concrete-filled column of the structure is that bending the material at a right angle and again bent at right angles to the bent end once and then, by bending material at a right angle again opened at a side corner post opening ( one end face plate is bent so that the pourable or that formed by bending the bending overlap forming S); And includes a connection maguripan connection hole is formed, is formed integrally with a lower surface and an upper surface, said connecting maguripan is to be the edge of the top surface and the bottom surface of the connection maguripan concrete-filled columns for the corners and the unit structure consistent with each other as a square plate form concrete a connection hole is formed so as to be protruding to the exposed side edges.
