Abstract
Abstract Prefabricated, modular structures, adapted for the erection of buildings in general, including a three-dimensional and a flat element which may be brought close to each other and such that the said three-dimensional element, having the shape of a rectangular trihedron consists of a slab of prolonged rectangular shape of convenient dimensions, from one of the shorter sides of which slab there extends a vertical wall of appropriate height, whereas from one of the longer sides of the same slab there extends a second vertical wall, brought close to one of the ends of the aforesaid wall, such second vertical wall having a lesser length than that of the slab so as to delimit on one side an opening.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A building, comprising a plurality of substantially identical three-dimensional trihedron-shaped prefabricated modular elements each having an elongated rectangular slab, a first wall projecting upwardly from one narrow side of said slab and a second wall projecting upwardly from one long side of said slab and having a free end portion extending from said first wall towards but short of the other narrow side of said slab, said three-dimensional elements being disposed in a plane orthogonal to each other and together bounding an interior building space, each of said free end portions defining with a wall of the other element a gap serving for the installation of doors and/or windows; and means bridging said three-dimensional elements, being located in said plane and covering the area of said building space which is left free by said three-dimensional elements.
Claim 2
Dependent Claim
136 words
A building, comprising a plurality of substantially identical three-dimensional trihedron-shaped prefabricated modular elements each having an elongated rectangular slab, a first wall projecting upwardly from one narrow side of said slab and a second wall projecting upwardly from one long side of said slab and having a free end portion extending from said first wall towards but short of the other narrow side of said slab, said three-dimensional elements being disposed in a plane orthogonal to each other and together bounding an interior building space, each of said free end portions defining with a wall of the other element a gap serving for the installation of doors and/or windows; and means bridging said three-dimensional elements, being located in said plane and covering the area of said building space which is left free by said three-dimensional elements.
Claim 3
Dependent Claim
21 words
A building as defined in claim 1, wherein said three-dimensional elements are arranged in sequential order with reference to one another.
Claim 4
Dependent Claim
20 words
A building as defined in claim 1, wherein said three-dimensional elements are arranged in alternate order relative to each other.
Claim 5
Dependent Claim
130 words
A building, comprising a plurality of substantially identical three-dimensional trihedron-shaped prefabricated modular elements each having an elongated rectangular slab, a first wall projecting upwardly from one narrow side of said slab and a second wall projecting upwardly from one large side of said slab and having a free end portion extending from said first wall towards but short of the other narrow side of said slab, said three-dimensional elements being arranged closely adjacent one another and together bounding an interior building space the floor, ceiling and side walls of which are at least partly formed by the cooperating walls and slabs of said three-dimensional elements, each of said free end portions defining with a wall of another of said elements a gap serving for the installation of doors and/or windows.
Claim 6
Dependent Claim
130 words
A building, comprising a plurality of substantially identical three-dimensional trihedron-shaped prefabricated modular elements each having an elongated rectangular slab, a first wall projecting upwardly from one narrow side of said slab and a second wall projecting upwardly from one large side of said slab and having a free end portion extending from said first wall towards but short of the other narrow side of said slab, said three-dimensional elements being arranged closely adjacent one another and together bounding an interior building space the floor, ceiling and side walls of which are at least partly formed by the cooperating walls and slabs of said three-dimensional elements, each of said free end portions defining with a wall of another of said elements a gap serving for the installation of doors and/or windows.
