Abstract

Abstract A self-supporting, modular structural panel comprises a rigid, opaque body panel of substantial thickness. One marginal edge portion of the body panel defines an integral, load-supporting beam which extends outwardly from a first major surface of the body panel. An exterior sheet member is bonded to and conforms to the contour of the body panel and beam. Marginal portions of the sheet are overlapped at an opposite marginal edge of the body panel to define an integral channel portion which extends outwardly from the first major surface of the body panel. The channel portion is configured to receive nestably and to interlock with the beam portion of a second structural member of like configuration.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 163 words
A self-supporting vertical wall section consisting essentially of a plurality of self-supporting modular structural members, each structural member including a rigid-foamed plastic body panel of substantial thickness, a marginal edge portion of the body panel defining an integral, vertically extending, roof-supporting beam portion which extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion of each structural member being nestably received and interlocked with the beam portion of another structural member of like configuration.
Claim 2
Dependent Claim 163 words
A self-supporting vertical wall section consisting essentially of a plurality of self-supporting modular structural members, each structural member including a rigid-foamed plastic body panel of substantial thickness, a marginal edge portion of the body panel defining an integral, vertically extending, roof-supporting beam portion which extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion of each structural member being nestably received and interlocked with the beam portion of another structural member of like configuration.
Claim 3
Dependent Claim 175 words
A roof of the type which includes two abutting sections, each section consisting essentially of a plurality of self-supporting modular structural members, each member including a rigid, foamed plastic body panel of substantial thickness, a marginal edge portion of the body panel defining and integral load-supporting beam portion which is substantially coextensive with the marginal edge and extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion of each member being nestably received and interlocked with the beam portion of another structural member of like configuration.
Claim 4
Dependent Claim 175 words
A roof of the type which includes two abutting sections, each section consisting essentially of a plurality of self-supporting modular structural members, each member including a rigid, foamed plastic body panel of substantial thickness, a marginal edge portion of the body panel defining and integral load-supporting beam portion which is substantially coextensive with the marginal edge and extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion of each member being nestably received and interlocked with the beam portion of another structural member of like configuration.
Claim 5
Dependent Claim 204 words
a self-supporting, modular structural member which provides sufficient load-bearing ability to support without additional load-bearing framework a building structure including a plurality of such structural members joined together in interlocking relationship, the structural member comprising a rigid, opaque body panel of substantial thickness, a marginal edge portion of the body panel defining an integral load-supporting beam portion which is substantially coextensive with the marginal edge and extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion being configured to receive nestably and to interlock with the beam portion of a second structural member of like configuration; and a metallized layer disposed between a second major surface of the body panel and the exterior sheet member.
Claim 6
Dependent Claim 204 words
a self-supporting, modular structural member which provides sufficient load-bearing ability to support without additional load-bearing framework a building structure including a plurality of such structural members joined together in interlocking relationship, the structural member comprising a rigid, opaque body panel of substantial thickness, a marginal edge portion of the body panel defining an integral load-supporting beam portion which is substantially coextensive with the marginal edge and extends outwardly with respect to a first major surface of the body panel; a sheet member bonded to the body panel and beam portion in surface-to-surface contact to define the exterior surfaces of the structural member and to conform to the contour of the body panel and beam portion; marginal portions of the exterior sheet member being overlapped at an opposite marginal edge of the body panel to define an integral channel portion which is substantially coextensive with the opposite marginal edge and extends outwardly with respect to the first major surface of the body panel, the channel portion being configured to receive nestably and to interlock with the beam portion of a second structural member of like configuration; and a metallized layer disposed between a second major surface of the body panel and the exterior sheet member.
