Abstract

Abstract A one-story building having a concrete foundation, a wooden roof and interior and exterior walls of precast concrete panel construction, the walls being formed from precast concrete panels and installed in place without benefit of rigid interconnecting joints therebetween. Additionally, the wall panels are connected to the foundation at their bottom ends, and to the wooden roof at their upper ends, by means of nonrigid, as opposed to rigid, connection. Each of the exterior wall panels has an inner, structural slab of steel-reinforced concrete, a thin intermediate layer of a compressive, insulative material and an equally thin outer layer, or skin, of wire-reinforced concrete. The interior walls of the building are interrupted by door openings, or the like, to permit expansion and contraction of each wall segment as an independent unit. Because of the lack of rigid structural ties between the separate panels of the building walls, and between the wall panels and other parts of the building, each of the panels is free to move independently without creating strains in the overall structure that could lead to cracking or spalling of its walls. Also, the intermediate layers of compressive, insulative material in the exterior wall panels cooperate to form a pliable cocoon around the structural inner portion of the exterior wall shell which serves to insulate that portion of the shell from ambient temperature extremes and cushions the outer skin from the force of movements within the wall proper.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 377 words
A structure comprising an exterior wall shell encircling an interior area, which wall shell cooperates with roof and foundation means to form a building: a. said exterior wall shell being formed from precast wall panels, each panel comprising an inner slab of reinforced concrete constituting the main or structural part of the panel and a layer of compressive, insulative material adherent to the outer face of said slab; b. said panels being arranged in slightly spaced apart side-edge to side-edge adjacency, with their concrete slab portions facing toward said interior area, to form said exterior wall shell; c. said exterior wall shell having a continuous layer or reinforced surfacing material adherent to the layers of compressive, insulative material on the concrete slab portions of said panels, which continuous layer forms a continuous integral outer skin from panel to panel on said shell; d. the layers of compressive, insulative material adherent to the concrete slab portions of said panels cooperating to form a cocoon around said slab portions and thereby insulate the latter against ambient temperature extremes and act as a shock absorbing cushion between said slab portions and said layer of reinforced surfacing material to protect the latter against damage from any movements of said concrete slab portions in the exterior wall shell of said structure; e. said exterior wall shell having no connecting means between the inner slabs of said wall panels which prevent relative movement therebetween during conditions of use, and said structure including cooperating fastening means for interconnecting said wall panels and said roof and foundation means; f. said cooperating fastening means being attached to said panels only at their inner slab portions and being adaptable to permit sufficient movement of the wall panels relative to said roof and foundation means whereby each panel is mechanically insulated from its adjacent structural environment to the extent that stress interaction between the panel and said environment, as a result of the influence of ambient and environmental conditions on the structure, is substantially avoided, and physical deterioration of the exterior wall shell of the sort brought about by such stress interaction between precast concrete wall panels, and between said panels and their adjacent structural enviroment, in a conventional building with precast concrete panel walls is substantially obviated.
Claim 2
Dependent Claim 377 words
A structure comprising an exterior wall shell encircling an interior area, which wall shell cooperates with roof and foundation means to form a building: a. said exterior wall shell being formed from precast wall panels, each panel comprising an inner slab of reinforced concrete constituting the main or structural part of the panel and a layer of compressive, insulative material adherent to the outer face of said slab; b. said panels being arranged in slightly spaced apart side-edge to side-edge adjacency, with their concrete slab portions facing toward said interior area, to form said exterior wall shell; c. said exterior wall shell having a continuous layer or reinforced surfacing material adherent to the layers of compressive, insulative material on the concrete slab portions of said panels, which continuous layer forms a continuous integral outer skin from panel to panel on said shell; d. the layers of compressive, insulative material adherent to the concrete slab portions of said panels cooperating to form a cocoon around said slab portions and thereby insulate the latter against ambient temperature extremes and act as a shock absorbing cushion between said slab portions and said layer of reinforced surfacing material to protect the latter against damage from any movements of said concrete slab portions in the exterior wall shell of said structure; e. said exterior wall shell having no connecting means between the inner slabs of said wall panels which prevent relative movement therebetween during conditions of use, and said structure including cooperating fastening means for interconnecting said wall panels and said roof and foundation means; f. said cooperating fastening means being attached to said panels only at their inner slab portions and being adaptable to permit sufficient movement of the wall panels relative to said roof and foundation means whereby each panel is mechanically insulated from its adjacent structural environment to the extent that stress interaction between the panel and said environment, as a result of the influence of ambient and environmental conditions on the structure, is substantially avoided, and physical deterioration of the exterior wall shell of the sort brought about by such stress interaction between precast concrete wall panels, and between said panels and their adjacent structural enviroment, in a conventional building with precast concrete panel walls is substantially obviated.
Claim 3
Dependent Claim 143 words
A structure in accordance with claim 1 in which each of the precast panels from which said exterior wall shell is formed has, in addition to said inner slab of reinforced concrete and said layer of compressive, insulative material, a portion of said outer layer of said reinforced surfacing material adherent to said layer of compressive, insulative material; and in which said panels are designed so that there are greater spaces between the edges of the portions of the other layer of surfacing material on adjacent ones, when they are positioned in side-edge to side-edge adjacency to form said shell, than between the remaining portions of the panels; and in which said exterior wall shell has a suitable filler occupying said spaces to unite said portions of the outer layer of surfacing material into said continuous layer constituting said skin on said shell.
Claim 4
Dependent Claim 57 words
A structure in accordance with claim 2 in which the layers of compressive, insulative material on said precast wall panels forming said exterior wall shell comprise rigid polyurethane foam and the portions of the outer layer of reinforced surfacing material adherent to said layers of compressive, insulative material are layers of concrete reinforced by suitable reinforcing wire.
Claim 5
Dependent Claim 74 words
A structure in accordance with claim 3 in which the edges of said portions of the outer layer of reinforced surfacing material bonding said spaces between said edges on adjacent panels are set back from the corresponding edges of said layers of compressive, insulative material, respectively, and said reinforcing wire extends outwardly from said edges of said portions of the outer layer to overlap in said spaces and provide reinforcement for said filler therein.
Claim 6
Dependent Claim 35 words
A structure in accordance with claim 4 in which said interior walls are formed from reinforced precast concrete panels and no interior wall extends for more than the span of a single panel-width without interruption.
Claim 7
Dependent Claim 15 words
A structure in accordance with claim 1 comprising a one-story building which has interior walls.
