Abstract
Abstract The disclosure sets forth a system for prefabricating modular boxlike units of concrete, in which the upper slab or top slab is poured together with the walls and then subsequently is lifted and placed upon a lower slab form, whereby the lower slab is poured to create monolithic structure with the top, side and partition walls. The outside walls and partition walls may also be precast and then placed in position with the pouring of the upper or top slab and then stripped monolithically with the upper slab.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
A system for prefabricating modular boxlike preformed units for assembly into building structures for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling slab form in a permanent, stationary position during the prefabrication of successive units, casting the ceiling slab in engagement with the outside walls to form a monolithic structure including the ceiling slab and the outside walls, moving the inner forms in their entirety, downwardly and angularly awAy from the outside walls and the ceiling form, maintaining the inner wall forms in a substantially vertical plane during their angular movement, removing the monolithic structure to a base slab form, then casting the lower floor slab in junction with the lower edges of the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
Claim 2
Independent Claim
154 words
A system for prefabricating modular boxlike preformed units for assembly into building structures for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling slab form in a permanent, stationary position during the prefabrication of successive units, casting the ceiling slab in engagement with the outside walls to form a monolithic structure including the ceiling slab and the outside walls, moving the inner forms in their entirety, downwardly and angularly awAy from the outside walls and the ceiling form, maintaining the inner wall forms in a substantially vertical plane during their angular movement, removing the monolithic structure to a base slab form, then casting the lower floor slab in junction with the lower edges of the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
Claim 3
Dependent Claim
19 words
The system of claim 1, said outside walls being precast and placed in position beneath the ceiling slab form.
Claim 4
Dependent Claim
15 words
The system of claim 1, in which said boxlike units are used for single housing.
Claim 5
Dependent Claim
20 words
The system of claim 1, in which the boxlike units are used as part of a modular prefabricated multi-floor construction.
Claim 6
Dependent Claim
30 words
The system of claim 1, in which partition walls are provided with recesses in their lower edges to enhance the pouring and passage of the concrete forming the floor slab.
Claim 7
Independent Claim
176 words
A system of prefabricating modular boxlike preformed units for assembly into building structure for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling form in a permanent, stationary position during the prefabrication of successive units, casting the ceiling slab in engagement with the outside walls, moving the inner forms, in their entirety downwardly and angularly away from the outside walls and the ceiling form, maintaining the inner wall forms in a substantially vertical plane during their angular movement away from the outside walls and the ceiling form, forming a filler joint at the junction of the ceiling slab and each outside wall, to produce a monolithic structure including the ceiling slab, the outside walls and the filler joints, removing the monolithic structure to a base slab form, then casting the lower floor slab in junction with the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
Claim 8
Independent Claim
176 words
A system of prefabricating modular boxlike preformed units for assembly into building structure for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling form in a permanent, stationary position during the prefabrication of successive units, casting the ceiling slab in engagement with the outside walls, moving the inner forms, in their entirety downwardly and angularly away from the outside walls and the ceiling form, maintaining the inner wall forms in a substantially vertical plane during their angular movement away from the outside walls and the ceiling form, forming a filler joint at the junction of the ceiling slab and each outside wall, to produce a monolithic structure including the ceiling slab, the outside walls and the filler joints, removing the monolithic structure to a base slab form, then casting the lower floor slab in junction with the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
Claim 9
Independent Claim
188 words
A system of prefabricating modular boxlike preformed units for assembly into building structures for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling slab form in a permanent, stationary position during the prefabrication of successive units, moving the inner wall forms from an open position to a closed position preparatory to the prefabrication of each unit, casting the ceiling slab in engagement with the outside walls to form a monolithic structure including the ceiling slab and the outside walls, moving the inner wall forms, in their entirety, downwardly and angularly away from the outside walls and the ceiling form to return said inner forms to their open position, maintaining the inner wall forms in a substantially vertical plane during their angular movement from the closed position to the open position, removing the monolithic structure to a base slab form, then casting the lower floor slab in junction with the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
Claim 10
Independent Claim

Claim 11
Independent Claim
199 words
A system of prefabricating modular boxlike preformed units for assembly into building structures for homes, apartments, factories, garages and the like, comprising providing inner and outer forms for the outside walls and a ceiling form for the ceiling top slab, maintaining the ceiling top slab form in a permanent, stationary position during the prefabrication of successive units, supporting the inner wall form for each wall by a hinged swivel bracket, moving said inner wall forms from an open position to a closed position preparatory to the prefabrication of each unit by directing each of said inner wall forms, in its entirety, in an angularly upward direction while maintaining the same in a substantially vertical plane, casting the ceiling slab in engagement with the outside walls to form a monolithic structure including the ceiling slab and the outside walls, moving the inner wall forms away from the outside walls and the ceiling form to return said inner forms to their open position, removing the monolithic structure to a base slab form then casting the lower floor slab in junction with the outside walls to form the integral modular boxlike unit, and thereafter removing the unit from the base slab form.
