Abstract
A roof structure and its components comprises a series of metal panels having flanges that interlock when the panels are laid side by side and which are subsequently tightly seamed together to convert the individual panels into an integrated roof forming membrane. The roof structure may be insulated through the use of a blanket vapor barrier and insulation under the panels preferably along with thermal blocks located over the purlins. The roof structure includes unique flexible panel mounting clips that attach the panels to the purlins in such a way as to permit the panels to expand or contract in response to temperature and pressure changes, thereby minimizing roof stressing.
Claims5
In a paneling construction adapted to be installed by attachment to spaced parallel structural supporting elements such as the roof purlins of buildings, said construction comprising a plurality of elongated panels laid over and transversely to such supporting elements with the side edges of the panels abutting, said panels having generally planar mid-portions lying close to the supporting elements and having upstanding seaming flanges on said side edges folded over and crimped together to provide a mechanical interlock, each of said panels having supporting portions for said seaming flanges, said supporting portions extending angularly upwardly away from each other and from the mid-portion of the panel whereby the supporting portions of adjacent panels define a tunnel-like area and clip means securing the panels to the structural supporting elements, each clip means including a base member, attaching means rigidly securing said base members and clip means to a structural supporting element in the tunnel-like area defined by the supporting portions of adjacent panels, said construction being characterized by:
- A. A rim portion incorporated in an intermediate part of each of the supporting portions of each panel, said rim portions lying substantially in a common plane and extending inwardly toward one another from and substantially perpendicularly to the seaming flanges,
- B. The base member of each of said clip means having an upstanding column with a top portion closely underlying and supporting said rim portions of the adjacent panels,
- C. A holding portion secured to the base member of each clip means and preventing outward movement of the holding portion, said holding portions projecting upwardly from the base member between, and being folded over and crimped together with, the seaming flanges of the adjacent panels to prevent relative movement therebetween,
- whereby said holding portion and the top portion of the base member co-act with the seaming flanges and with said attaching means to prevent movement of the seaming flanges and of the supporting portions of the panels toward and away from the structural supporting elements and also to hold the holding portion against movement toward the base member.
