THREE-DIMENSIONAL FRAMEWORK STRUCTURE

PURPOSE:To provide a structure having sufficiently strong joints between gusset plates and a perimeter column, which can be built easily from fewer gusset plates. CONSTITUTION:A roof part 3 is formed by setting-up a plurality of framework members 41, 42 in lattice shape, and a perimeter column 1 supporting a side 3a of the roof part 3 and the end parts of the framework member 41, 42 are joined together through gusset plates 8. A point P at which gauge lines g1, g2 on the framework members 41, 42 intersect with the center line of the perimeter column 1 is provided shifting from a surface 1a on a gusset for fitting the perimeter column 1 to the side of an axis (O) of the column 1. In this three- dimensional framework structure, the gusset plates 8 are composed of a pair of fitting plates 81, 82 with which the end parts of the framework members 41, 42 are respectively joined and which are formed almost in the shape of a letter V. Ends 8a of the fitting plates 81, 82, which ends are on the side of the column 1, are positioned apart each other and are fitted to the surface 1a.
