Abstract
Abstract A plastic covered building structure comprised of a metal frame supporting superimposed layers of plastic sheets having an inflated area between the sheets providing insulation to the interior of the structure. The super-imposed plastic sheets are secured to the frame by means of longitudinally extending rails having longitudinally extending upwardly concave portions and complementary clamping rods adapted to secure the edges of the super-imposed plastic sheets between the rods and the upwardly concave portions of the rail. The rails are adapted to receive clamping members at any point along the length of the rails to clamp the rods into the upwardly concave portions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
A rail member for fastening sheets of plastic to a building structure which comprises an elongated rail having a top, bottom, and side surfaces, an upwardly concave portion integral with and on one side of said rail and longitudinally extending the length thereof, a clamping rod received in the concave portion of said rail and extending the length thereof, a longitudinally extending channel in the top surface of said rail having longitudinally extending grooves in the opposing vertical walls thereof, the grooves in the opposing walls being in staggered relationship, at least one bolt having a thread with an identical pitch as the grooves in said channel, and at least one clamp secured to said rail by said bolt and clamping said rod in The concave portion of said rail, whereby said clamp may be secured to said rail to clamp said rod in any position along the length of said rail.
Claim 2
Dependent Claim
152 words
A rail member for fastening sheets of plastic to a building structure which comprises an elongated rail having a top, bottom, and side surfaces, an upwardly concave portion integral with and on one side of said rail and longitudinally extending the length thereof, a clamping rod received in the concave portion of said rail and extending the length thereof, a longitudinally extending channel in the top surface of said rail having longitudinally extending grooves in the opposing vertical walls thereof, the grooves in the opposing walls being in staggered relationship, at least one bolt having a thread with an identical pitch as the grooves in said channel, and at least one clamp secured to said rail by said bolt and clamping said rod in The concave portion of said rail, whereby said clamp may be secured to said rail to clamp said rod in any position along the length of said rail.
Claim 3
Dependent Claim
79 words
The rail member as defined in claim 1 which further comprises a second upwardly concave portion integral with and on an opposing side of said rail from said first upwardly concave portion and longitudinally extending the length of said rail, and a second clamping rod received in said second concave portion and extending the length of said rail, said second rod being clamped into said concave portion by the clamp clamping said first rod into the first concave portion.
Claim 4
Dependent Claim
26 words
