Abstract: A 3-dimensional modular construction system using only two, generally U-shaped prefabricated room size modules is used to form scalable, modular construction for schools, apartments, hotels, houses and the like. The modules may be formed of reinforced concrete. By using the above described modules, double walls within the buildings are eliminated thus, simplifying construction and reducing material and costs, while becoming a container for the pre-finishing of the spaces.

Abstract: A modular construction system uses preformed room-size U-shaped modules and preformed room-size L-shaped modules to form modular housing such as apartments, hotels and the like. The modules may be formed of reinforced concrete. By using U-shaped modules juxtaposed, perpendicular or in parallel (along their edges) with one another, in combination with rotated L-shaped modules, double walls within units may be avoided, thus simplifying construction and reducing costs.

Abstract: A modular plural-story building construction system having (a) a series of rectangular modules, each having only two bounding planes for transmitting vertical loads opposite each other and joined by a floor panel and open on top, and (b) a series of rectangular modules, each having only two bounding planes for transmitting vertical loads opposite each other and joined by both a floor panel and a ceiling panel. The (b) modules are used only on the top story, and the (a) modules are used for all lower units. The modules on each level are installed with conjugation of the location of the bearing walls, i.e., so that the bounding planes for transmitting vertical loads of any one module lie perpendicular to the planes of the bounding planes for transmitting vertical loads of all immediately adjacent modules on the same level. The modules on successive levels are arranged so that the bounding planes for transmitting vertical loads above are aligned with those below.
