Steel structure for prefabricated buildings

Claim 1

A steel structure for prefabricated building to be assembled on a foundation which comprises: a plurality of column-girder members each comprising: a pair of H-shaped columns each having a web and flanges, said columns being depthwise spaced from each other with said webs facing each other, a steel girder extending in said depthwise direction and directly attached to and connecting said columns, and a pair of corridor board supporting girders, one each directly attached to said columns and extending axially in the same direction as said steel girders; said plurality of column-girder members being vertically connected at the columns thereof and spaced in the direction transverse to said depthwise direction; a plurality of steel crossbeams each directly attached to and connecting said flanges of a pair of transversely adjacent columns of said transversely spaced column-girder members, a plurality of braces connecting said columns and said steel girders of said vertically connected column-girder members; said crossbeams together with said columns and steel girders defining a plurality of framed space sections; a plurality of capsule units dimensioned to be selectively positioned within said framed space sections; the opposed sides of all of said framed space sections in said depthwise direction being completely open, whereby said capsule units may be selectively inserted therein or withdrawn therefrom in either of the opposed depthwise directions; and said capsule units being directly fastened to the upper surfaces of said steel crossbeams.
