Patent ID: 8763326

Claim:
A building structure which has a whole shape formed by connecting at least horizontally a plurality of unit spaces ( 10 ) each in the shape of a polygonal prism having a pair of upper and lower end faces (T, W) defining roof and floor regions respectively, and a plurality of indoor and outdoor facing side faces (S), the unit spaces sharing a side face if horizontally adjacent to each other and sharing an end face if vertically adjacent to each other, comprising: a main hexagonal frame ( 1 A, 1 B, 1 C) standing in each outdoor side face among the side faces (S) of each unit space; an edge beam ( 2 A 1 , 2 A 2 , 2 B 1 , 2 C 1 , 2 C 2 , 2 D 1 , 3 A, 3 B, 3 C) arranged at an edge of the upper end face (T) of each unit space that is not occupied by a member of the main hexagonal frame; an indoor pillar ( 4 A, 4 B) arranged on each indoor side face among the left sides (c) and right sides (d) of the side faces (S) of each unit space, the indoor pillar extending continuously from the roof region to the floor region so as to provide support for the building structure; an upper side ( 1 A 1 ) and a lower side ( 1 A 2 ) of the main hexagonal frame, the upper side ( 1 A 1 ) and the lower side ( 1 A 2 ) of the main hexagonal frame are located on an upper side (a) and a lower side (b) of the outdoor side face, respectively; and are generally planar with the roof and floor regions, respectively; left and right bend portions ( 1 A 7 , 1 A 8 ) of the main hexagonal frame, each bend portion having a vertex; the left and right bend portions of the main hexagonal frame are located on a left side (c) and a right side (d) of the outdoor side face, respectively whereby the left and right bend portions of each outdoor side face are joined at their vertices to the vertices of the right and left bend portions respectively of an adjacent outdoor side face; and the main hexagonal frame, the edge beam and the indoor pillar are joined to each other.
