Abstract
Abstract A prefabricated room unit designed for use in constructing modular buildings. The prefabricated room unit is formed of a plurality of identical sheet metal panels of substantially Ushaped cross section. The walls of the room are formed by disposing the sheet metal panels side-by-side having their adjacent lateral flanges joined. The floor of the room unit is formed of substantially identical panels mounted in pairs with their web portions in contact and secured to each other so that each combination of two sheet metal panels forms an I-type beam.
