摘要

In the embodiment of the invention described herein and shown in the accompanying drawings, a transportable prefabricated room element has a rigid frame or chassis which comprises a rigid base structure or floor panel structure and a vertical load-bearing structure permanently and rigidly fixed to the floor panel structure at an intermediate region in the length of the latter. This frame or chassis is preferably of inverted T formation in side elevation. At each side of the vertical structure, there is a prefabricated three-dimensional cell unit, each of which units consitutes a three-dimensional region of the room element and has a vertical wall and a roof or ceiling and/or a floor and is assembled to or with the frame or chassis in substantially-finished condition. At each end the floor panel structure freely supports at least one vertical load-bearing strut for carrying vertical loads imposed by a superimposed room element. These struts are at least partly enclosed in end walls of the extreme cell units. The extreme end walls of the cell units substantially coincide with or slightly overlap the ends of the floor panel structure. In a plural story building, the room elements are stacked on one another with their vertical load-bearing structures in register, and these registering vertical structures are post-tensioned together by post-tensioning means extending down through them:-possibly into a foundation of the building.
