Abstract
Abstract Modular and other units of concrete or similar matter, generally precast for various constructions and buildings, and housing. The modular units have portions which are adapted to hold slabs to link two consecutive modules, the modules can be stacked vertically, and the system comprising such modules and slabs can be extended laterally and longitudinally to form a great variety of buildings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
214 words
A pair of modular units coupled in vertical relationship, the bottom modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a load-bearing ledge which has a surface in a plane substantially parallel to the plane of the top member and is integral with and extends on the outer face of the leg member and said modular unit having a connecting member comprising a loop member permanently set into a rib which is an integral part and protrudes from the top member of the modular unit, and a modular unit positioned above the bottom unit, said modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member, at least one leg member of said modular unit defining at least one recess which is open to the bottom of the base of the leg, the connecting member of the bottom modular unit being engaged in the recess of the top modular unit, the modular units being thus vertically stacked in static relationship by means of a hardened mass filling the recess within the leg of the modular unit.
Claim 2
Dependent Claim
214 words
A pair of modular units coupled in vertical relationship, the bottom modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a load-bearing ledge which has a surface in a plane substantially parallel to the plane of the top member and is integral with and extends on the outer face of the leg member and said modular unit having a connecting member comprising a loop member permanently set into a rib which is an integral part and protrudes from the top member of the modular unit, and a modular unit positioned above the bottom unit, said modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member, at least one leg member of said modular unit defining at least one recess which is open to the bottom of the base of the leg, the connecting member of the bottom modular unit being engaged in the recess of the top modular unit, the modular units being thus vertically stacked in static relationship by means of a hardened mass filling the recess within the leg of the modular unit.
Claim 3
Dependent Claim
14 words
The pair of modular units of claim 1 wherein the hardened mass is grout.
Claim 4
Dependent Claim
23 words
The pair of coupled modular units of claim 2 wherein each leg member of the bottom modular unit has a load bearing ledge.
Claim 5
Dependent Claim
27 words
The pair of coupled modular units of claim 2 wherein each leg member of the modular unit positioned above the bottom unit has a load bearing ledge.
Claim 6
Dependent Claim
9 words
The units of claim 1 which are of concrete.
Claim 7
Dependent Claim
10 words
The units of claim 1 which are of precase concrete.
Claim 8
Independent Claim
217 words
A method of construction which comprises coupling a first moular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member and said modular unit having a connecting member comprising a loop member permanently set into a rib which is an integral part and protrudes from the top member of the modular unit with a second modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member, at least one leg member of the modular unit defining at least one recess which is open to the bottom of the base of the leg, by fitting the loop member of the first modular unit into the recess of the base of the leg of the second modular unit, thereby mating said two elements and forming a self-sustaining static building which defines a multiplicity of habitable spaces, inserting a hardenable material into the recess of the leg of the modular unit in which the connecting member is positioned and allowing it to harden to form a hardened mass.
Claim 9
Independent Claim
217 words
A method of construction which comprises coupling a first moular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member and said modular unit having a connecting member comprising a loop member permanently set into a rib which is an integral part and protrudes from the top member of the modular unit with a second modular unit having two spaced leg members integrally connected by a top member, at least one of the leg members having a ledge which is integral with and extends on the outer face of the leg member, at least one leg member of the modular unit defining at least one recess which is open to the bottom of the base of the leg, by fitting the loop member of the first modular unit into the recess of the base of the leg of the second modular unit, thereby mating said two elements and forming a self-sustaining static building which defines a multiplicity of habitable spaces, inserting a hardenable material into the recess of the leg of the modular unit in which the connecting member is positioned and allowing it to harden to form a hardened mass.
Claim 10
Dependent Claim
11 words
ThE method of claim 7 wherein the hardened mass is grout.
Claim 11
Dependent Claim
30 words
The method of claim 7 wherein each leg member has a ledge and a recess and both loop members are fitted into the recess of the base of the leg.
Claim 12
Dependent Claim
29 words
The method of claim 9 which comprises inserting a hardenable material into the recesses of the legs in which the connecting member is positioned and allowing it to harden.
Claim 13
Dependent Claim
11 words
The method of claim 10 wherein the hardened material is grout.
