ABSTRACT:
A modular steel utility structure and a method of assembly is disclosed. The construction employs a plurality of vertical steel columns and horizontal frames. Each column has capital and basal steel erection plates secured at respective upper and lower ends. The capital plate has from one to four pins extending upwardly therefrom and laterally off-set from the column. Each basal plate has a corresponding number of apertures similarly spaced from the column. Each frame has a top and bottom erection plate secured at each corner thereof. The bottom erection plate has an aperture spaced from the frame members for receiving the pin from a capital plate of a column immediately therebeneath for registration therewith. The top erection plate has an upwardly projecting pin which is received in register by the aperture on a basal plate of a column in the story or level immediately above it. In this manner, the structure is assembled by positioning a story or level of columns with a crane, and then by placing the prefabricated frames in position to be supported by the columns. Additional stories are added by successively positioning tiers of columns and frames. The adjacent erection plates on the columns and frames may be bolted together or otherwise secured for additional stability.
