Abstract
Abstract A wall construction including a first rigid panel engaging a first elongated spline extending lengthwise of the panel and facing to one side thereof, the spline having elongated shoulder portions for engaging a second rigid panel on one side thereof. An elongated T-shaped spline is connected to the first spline via a web portion thereof while flange portions of the T-shaped spline engage the side of the second panel opposite to and in alignment with the shoulder portions of the first spline. This combination provides a firm, rigid structure for driving a fastening means through the flange portions of the T-shaped spline for securing a third panel to the second panel via the flange portions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
In a wall construction a first panel structure including two rigid panels having adjacently disposed, elongated end portions, a second panel structure disposed on one side of and substantially parallel to said first panel structure, said second panel structure including two rigid panels having adjacently disposed end portions in substantial alignment with those of said first panel structure, an elongated splice member having a channel portion joining together the end portions of said first panels, and elongated flange portions engaging said second panels on one side thereof, an elongated and substantially continuous T-spline having a web portion located between the end portions of said second panels, and connected to said splice member, said T-spline further having elongated and substantially continuous flange portions engaging said second Panels on the side thereof opposite to the side engaging the flange portions of said splice member, the flange portions of said splice member and T-spline together with said second panels providing a firm combination for driving a fastening means through the flange portions of said T-spline.
Claim 2
Dependent Claim
172 words
In a wall construction a first panel structure including two rigid panels having adjacently disposed, elongated end portions, a second panel structure disposed on one side of and substantially parallel to said first panel structure, said second panel structure including two rigid panels having adjacently disposed end portions in substantial alignment with those of said first panel structure, an elongated splice member having a channel portion joining together the end portions of said first panels, and elongated flange portions engaging said second panels on one side thereof, an elongated and substantially continuous T-spline having a web portion located between the end portions of said second panels, and connected to said splice member, said T-spline further having elongated and substantially continuous flange portions engaging said second Panels on the side thereof opposite to the side engaging the flange portions of said splice member, the flange portions of said splice member and T-spline together with said second panels providing a firm combination for driving a fastening means through the flange portions of said T-spline.
Claim 3
Dependent Claim
48 words
The structure of claim 1 including a third panel located on the side of the second panel structure remote from the first panel structure, and fastening means extending through said third panel and into the flange portions of the T-spline for securing said third panel to the T-spline.
Claim 4
Dependent Claim
71 words
The structure of claim 1 including a third panel located on the side of the second panel structure remote from the first panel structure, and nails extending through said third panel and into the flange portions of the T-spline, said nails having threaded shank portions, and the flange portions of said T-spline having a burr surrounding the threaded shank portions of each nail to secure the same in the flange portions.
Claim 5
Dependent Claim
49 words
The structure of claim 1 in which the splice member has an elongated U-shaped portion facing in the direction of the T-spline, the web of the T-spline having an end portion extending into said U-shaped portion, and means within said U-shaped portion gripping the end portion of said web.
