Abstract
Abstract Structural units comprising laminated, skin-stressed, panels and attendant components are joined in various combinations by connecting members so as to form frameless, load-carrying structures affording a clear span desirable not only in commercial, industrial and institutional applications but in residential construction as well. The structural system especially lends itself to factory manufacture and assembly in maximum size transportable sections completely finished for jobsite installation on pre-arranged foundations. The term panel is used herein in its broadest sense and denotes a structural member substantially greater in the dimensions of length and width than in thickness. The term structural unit is more comprehensive than the term panel and includes not only a panel but also various components associated with a panel.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
136 words
A building structural system comprising: a. a plurality of laminated structural units, each unit including a pair of metal skins, each skin having an outer surface and an inner surface, and a core of material having low thermal conductivity bonded to said inner surfaces of said skins, said laminated units being rectangular and extending longitudinally between opposite ends and transversely between opposite sides, said ends and said sides being defined by marginal edges; and b. connector means for joining said units along adjacent marginal edges, said unit connector means including a pad comprising a sealing strip of resilient material mounted on each of the adjacent edges of said units, and a metal web located on the exposed face Of each of said resilient sealing strips, said metal webs being arranged in abutting relation and fastened together.
Claim 2
Dependent Claim
136 words
A building structural system comprising: a. a plurality of laminated structural units, each unit including a pair of metal skins, each skin having an outer surface and an inner surface, and a core of material having low thermal conductivity bonded to said inner surfaces of said skins, said laminated units being rectangular and extending longitudinally between opposite ends and transversely between opposite sides, said ends and said sides being defined by marginal edges; and b. connector means for joining said units along adjacent marginal edges, said unit connector means including a pad comprising a sealing strip of resilient material mounted on each of the adjacent edges of said units, and a metal web located on the exposed face Of each of said resilient sealing strips, said metal webs being arranged in abutting relation and fastened together.
Claim 3
Dependent Claim
23 words
a web located on the exposed face of each of said sealing strips, said webs being arranged in abutting relation and fastened together.
Claim 4
Dependent Claim
23 words
a web located on the exposed face of each of said sealing strips, said webs being arranged in abutting relation and fastened together.
Claim 5
Dependent Claim
68 words
A building structural system as in claim 1 further including a beam interposed between each of said pads and said metal webs, said beam having a thickness such as to provide additional dimensional precision and structural strength to the joint formed by the adjacent marginal edges of said units, and by said webs and said pads when tightly connected together with adjacent surfaces in face to face engagement.
Claim 6
Dependent Claim
45 words
a core of material having low thermal conductivity interposed between said pair of skins and bonded to said inner surfaces thereof; said laminated units being defined by marginal edges; and, b. connector means for joining said units along adjacent marginal edges, said connector means including:
Claim 7
Dependent Claim
45 words
a core of material having low thermal conductivity interposed between said pair of skins and bonded to said inner surfaces thereof; said laminated units being defined by marginal edges; and, b. connector means for joining said units along adjacent marginal edges, said connector means including:
Claim 8
Dependent Claim
61 words
A building structural system as in claim 1 wherein one edge of each of said metal webs is substantially flush with the plane of one side surface of adjacent pairs of units, and the other edge of each of said metal webs extends beyond the plane of the other side surface of said adjacent pairs of units to form a projection.
Claim 9
Dependent Claim
35 words
A building structural system as in claim 1 wherein both edges of said metal webs extend beyond the corresponding planes of said side surfaces of said units to form a pair of oppositely extending projections.
Claim 10
Dependent Claim
27 words
A building structural system as in claim 1 wherein both edges of said metal webs are flush with the planes of said side surfaces of said units.
Claim 11
Dependent Claim
30 words
A building structural system as in claim 2 wherein both edges of said webs and said beams are flush with the corresponding planes of said side surfaces of said units.
Claim 12
Dependent Claim
57 words
A building structural system as in claim 2 wherein one edge of said webs and said beams are substantially flush with the corresponding planes of one of said side surfaces of said units and the opposite edge of said webs and said beams project from the planes of the other of said side surfaces of said units.
Claim 13
Dependent Claim
29 words
A building structural system as in claim 2 wherein both edges of said webs and said beams project from the corresponding planes of said side surfaces of said units.
Claim 14
Dependent Claim
18 words
A building structural system as in claim 1 including elongated protective cap means for covering said connector means.
Claim 15
Dependent Claim
48 words
A building structural system as in claim 9 wherein said protective cap means comprise an elongated strip of material having an inverted U-shape in transverse section, and means for securing said cap means to the adjacent portions of a pair of abutting units connected by said connector means.
Claim 16
Dependent Claim
15 words
A building structural system comprising: a. a plurality of laminated structural units, each unit including:
Claim 17
Dependent Claim
15 words
A building structural system comprising: a. a plurality of laminated structural units, each unit including:
Claim 18
Dependent Claim
67 words
A building structural system as in claim 11 further including a beam interposed between each of said pads and said webs, said beam having a thickness such as to provide additional dimensional precision and structural strength to the joint formed by the adjacent marginal edges of said units and by said webs and said pads when tightly connected together with adjacent surfaces in face to face engagement.
