Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
226 words
In a roof structure, a series of interlocked roof panels having adjacent margins forming rib joints and being of self-supporting capacity and closing the space between said purlins, rigid insulation sandwiched between said panels and said purlins, an integral, one-piece bearing support member overlying said rigid insulation of each said rib joint, said bearing support member comprising a pair of upper coplanar portions and an intermediate lower planar portion lying in a plane parallel to that of said coplanar portions, said coplanar portions and said intermediate lower portion being joined by a pair of downwardly extending portions to form a recess extending fully between opposite edges of said bearing support, said panels being connected to said bearing support, and a concealed fastener and associated through fastener means positioned along said rib joint in said recess to anchor said bearing support member to said purlin, each said concealed fastener having a foot extending from the lower end thereof for anchoring pairs of rigid interlocked metal panels at said rib joints, the foot of each said concealed fastener being contiguous with said lower portion, said recess of said bearing support member being tightly pulled into said rigid insulation an amount about equal to the depth of said recess such that the lower surfaces of said coplanar portions are substantially contiguous with the upper surface of said rigid insulation.
Claim 2
Dependent Claim
226 words
In a roof structure, a series of interlocked roof panels having adjacent margins forming rib joints and being of self-supporting capacity and closing the space between said purlins, rigid insulation sandwiched between said panels and said purlins, an integral, one-piece bearing support member overlying said rigid insulation of each said rib joint, said bearing support member comprising a pair of upper coplanar portions and an intermediate lower planar portion lying in a plane parallel to that of said coplanar portions, said coplanar portions and said intermediate lower portion being joined by a pair of downwardly extending portions to form a recess extending fully between opposite edges of said bearing support, said panels being connected to said bearing support, and a concealed fastener and associated through fastener means positioned along said rib joint in said recess to anchor said bearing support member to said purlin, each said concealed fastener having a foot extending from the lower end thereof for anchoring pairs of rigid interlocked metal panels at said rib joints, the foot of each said concealed fastener being contiguous with said lower portion, said recess of said bearing support member being tightly pulled into said rigid insulation an amount about equal to the depth of said recess such that the lower surfaces of said coplanar portions are substantially contiguous with the upper surface of said rigid insulation.
Claim 3
Dependent Claim
16 words
The roof structure according to claim 1, wherein said upper portions are of the same width.
Claim 4
Dependent Claim
23 words
The structure according to claim 1, wherein the free edge of one of said upper portions is provided with a downwardly depending flange.
Claim 5
Dependent Claim
14 words
The structure according to claim 1, wherein said downwardly portions slope toward each other.
Claim 6
Dependent Claim
18 words
The bearing support according to claim 1, wherein said lower portion is provided with a central perforation therein.
Claim 7
Dependent Claim
86 words
The structure according to claim 5, wherein said foot comprises a return bent flange having an elongated slot formed therein extending longitudinally thereof, a washer member located on said return bent flange, said washer member comprising a U-shaped member which is snuggly received on and said return bent portion, and an aperture through the legs of said U-shaped member in alignment with said elongated slot in said return bent flange, said associated through-fastener extending through said aperture, said elongated slot, and said perforation into said purlin.
Claim 8
Dependent Claim
185 words
The structure according to claim 6, wherein each said through fastener comprises a self-drilling screw having a shoulder between the head and shank thereof, the diameter of said central perforation in said bearing support member being less than that of said aperture in said washer member and the transverse width of said slot in said foot but such as to allow said shoulder to pass through said aperture in the legs of said U-shaped member and said slot in said return bent flange but not the aperture in said bearing support member, and the length of said shoulder being slightly greater than the combined thicknesses of said foot and said washer member, whereby when said fastener is anchored to said purlin the bottom of said shoulder abuts the top surface of said bearing support and the bottom of said fastener head is precluded from contacting the upper surface of said washer member when the recess of said bearing support is tightly pulled into said insulation but said concealed fastener is precluded from being pinched tightly into contact with the upper surface of said bearing support.
Claim 9
Dependent Claim
27 words
The structure according to claim 1, including a plurality of coplanar portions adjacent pairs of which are joined together by said lower portions and said downwardly portions.
Claim 10
Dependent Claim
14 words
The structure according to claim 8 wherein said upper portions are the same width.
Claim 11
Dependent Claim
14 words
The structure according to claim 8 wherein said lower portions are the same width.
Claim 12
Dependent Claim
30 words
The structure according to claim 8, wherein each said lower portion is provided with an elongated slot formed therein extending longitudinally thereof and being substantially parallel to said upper portions.
