Modular unit having variable cross section beam and modular unit structure using the same

The present invention horizontal coupling between the modular unit and the modular unit having a tapered thousand information formed in a large cross-section both side portions of the fabric information, and to form the central portion to the smaller cross-section which can resist only gravity load of the ceiling so as to have a structure of a tapered section modular and by upper and lower coupling fitting to connect the reinforcing plate during the lamination bonding to the parameters between the units, to a modular unit structures to ensure the integral behavior of the modular unit to increase the lateral resistance of the entire structure. According to one preferred embodiment of a modular unit having a tapered thousand information of the present invention, the pillars and, in the modular unit, the cloth information composed of cloth information and bottom beams, each connecting the top and the bottom of the column is constant and an upper plate having a width, bokbupan extending vertically downwardly from one end of the upper plate, and consists of a bottom plate extending horizontally from the lower end of the central portion bokbupan member is formed to have a cross-section with c-party; Is formed can have the same width as the top plate of the center member flat and can extend vertically downward from one end of the plate consists of a vertical plate may be formed higher than the height of the bokbupan of the center member so as to have a a character section, the center member integrally formed on both ends or are formed by bonding separately formed abutting bokbupan and vertical plates of the center member, and an end member formed in the top plate and the height plate upper same on the middle member, made of a, cross-sectional dimension of the center member is formed smaller than the size of the cross section of the end members, it is bonded to the center pin member and the end member.
