Abstract
Abstract A building structure comprising a corrugated protective layer (11) having crests (17) and valleys (18), a plurality of rigid metal securement strips (26) applied over the corrugated protective layer (11), an outer weather-resistant covering (38) applied over the rigid metal securement strips (26), and connecting means (22) for securing said building elements together. A layer of insulation (37) may be included between the rigid metal securement strips (26) and exterior weather-resistant covering (38). The outer weather-resistant covering (38), the layer of insulation (37), and the metal securement strips (26) can be secured to the corrugated protective layer (11) without disturbing the preexisting structure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
61 words
A building structure comprising a corrugated-like inner sheath configurated with crests and valleys, characterized by a plurality of rigid metal securement strips applied in a spaced arrangement over the inner sheath so as to transversely span the crests of the sheath, an outer weather-resistant covering applied over the rigid metal securement strips, and connecting means for securing said building elements together.
Claim 2
Dependent Claim
61 words
A building structure comprising a corrugated-like inner sheath configurated with crests and valleys, characterized by a plurality of rigid metal securement strips applied in a spaced arrangement over the inner sheath so as to transversely span the crests of the sheath, an outer weather-resistant covering applied over the rigid metal securement strips, and connecting means for securing said building elements together.
Claim 3
Dependent Claim
47 words
The building structure of claim 1, wherein the inner sheath is secured to its substructure by fastening means which extends through and projects exteriorly of the inner sheath, and characterized in that the metal securement strips are secured to the inner sheath.by attachments to said fastening means.
Claim 4
Dependent Claim
91 words
The building structure of claim 2, wherein the inner sheath is a member selected from the group consisting of a cement asbestos roof and a metal sheeting roof, the inner sheath being secured to a plurality of underlying parallel spaced purlins by horizontally extending fasteners whose upper ends extend through. and project exteriorly of the crests of the inner sheath, and characterized in that each of the metal securement strips comprises a long, thin strip which is secured to the inner sheath by attachments to the upper ends of the fasteners.
Claim 5
Dependent Claim
160 words
The building structure of claim 3, wherein the inner sheath is secured to the underlying purlins by horizontally extending bolts whose upper free ends extend through and project exteriorly of the crests of the inner sheath, a washer and nut combination being placed onto each of the bolts and adjacent the crest upper surface to fasten the bolt, and characterized in that each of the metal securement strips comprises a long, thin strip having a longitudinally extending central section with downwardly and outwardly extending sidewalls integrally connected along the two longitudinally extending edges of the central section, and apertured dimples centrally located on the strip central section and spaced along its length so as to enclose each of the washer and nut combinations and to permit the bolt upper free end to penetrate through its aperture, and a second washer and nut combination is placed onto each of the bolts and adjacent the dimple upper surface to fasten the bolt.
Claim 6
Dependent Claim
35 words
The building structure of claim 4, characterized in that the longitudinally extending metal securement strips of each roof span comprise a number of strips placed lengthwise one after the other in an end-to-end overlapping arrangement.
Claim 7
Dependent Claim
28 words
The building structure of any of claims 1 to 5, characterized in that a layer of insulation is included between the metal securement strips and outer weather-resistant covering.
Claim 8
Dependent Claim
19 words
The building structure of claim 6, characterized in that the outer weather-resistant covering comprises a roll formed aluminum sheet.
Claim 9
Dependent Claim
52 words
The building structure of claim 6 or 7, characterized in that the layer of insulation is a foam plastic insulation board, a composite foam/cellulose fiber insulation board, a perlite insulation board, a composite board of perlite and plastic foam, a rigid wood fiber insulation board, and a surfaced semi-rigid blanket thermal insulation.
Claim 10
Dependent Claim
35 words
The building structure of claim 7, characterized in that the outer weather-resistant covering, the layer of insulation and the metal securement strips are secured together by fasteners which penetrate through the three said building elements.
Claim 11
Independent Claim
59 words
A method of installing an exterior structure onto an existing corrugated-like inner sheath configurated with crests and valleys, characterized by securing a plurality of rigid metal securement strips in a spaced arrangement over the inner sheath so as to transversely span the crests of the sheath, and further securing an outer weather-resistant covering over the rigid metal securement strips.
