Abstract

Roofing means including a roof panel. Means are provided for securing the roof panel onto a roof frame including elastic clamping means joining the panel in tensioned relation to the frame and a deformable elastic sealing member secured between the clamping means and the panel and covering the clamping member. The roof panel may be a thin translucent plastic sheet.

Claims

1. Roofing means comprising a panel capable of withstanding tension loads, means for securing the panel onto a frame comprising an elastic tensioned clamping member joining said panel in tensioned relation to said frame and a deformable elastic sealing member secured between said clamping member and said panel, said elastic clamping member comprises a clamping member having a channel adapted to receive the edge of said panel and a spline which can be jammed into said channel together with said panel edge to hold said panel edge in firm frictional clamped relation with said clamping member.

2. Roofing means according to claim 1, in which said deformable elastic sealing member is a strip of weather-resistant elastomer having at least one sealing bead and said clamping member has an overhung channel suitable to hold said sealing bead in compressed sealing contact with said panel.

3. Roofing means according to claim 2, in which said clamping member has an outer portion extending outside the plane of said panel, and said elastic seal member has a web portion which covers said outer portion of said clamping member to protect said clamping member from corrosion by rain.

4. Roofing means according to claim 1, in which said clamping member includes a prebent portion which is elastically straightened upon assembly to a beam of the said roof frame to maintain tension in said panel.

5. Roofing means according to claim 1, in which at least the lower inside face of said channel has projections which engage the surface of the said panel.
