Building structure

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) and a plurality of 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 (1A, 1B, 10) standing in each outdoor side face among the side faces (S) of each unit space;
• an edge beam (2A1, 2A2, 2B1, 2C1, 2C2, 2D1, 3A, 3B, 3C) arranged in the place not occupied by a member of the main hexagonal frame at the edge of the upper end face (T) of each unit space;
• an indoor pillar (4A, 4B) arranged on each indoor side among the left sides (c) and right sides (d) of the side faces (S) of each unit space, wherein:
• an upper side (1A1) and a lower side (1A2) of the main hexagonal frame are located on an upper side (a) and a lower side (b) of the outdoor side face, respectively, and left and right bend portions (1A7, 1A8) of the main hexagonal frame are located on a left side (c) and a right side (d) of the outdoor side face, respectively;
• and
• the main hexagonal frame, the edge beam and the indoor pillar are joined to each other.
