Insulated roof structure with fire resistant panels mounted thereon
First Claim
1. A method of fire proofing a roof structure of a building of the type including a plurality of spaced apart rafters and a plurality of spaced parallel purlins mounted on the rafters, comprising the steps of:
- mounting a plurality of support beams to the lower surfaces of the purlins;
positioning a plurality of fire resistant panels against the lower surfaces of the support beams with the side edges of successive panels overlapping the adjacent side edges of adjacent panels thereby forming compression gaps between adjacent panelsattaching the fire resistant panels to the support beams at positions away from the compression gaps;
compressing the overlapping side edges of the fire resistant panels into the compression gaps formed between adjacent fire resistant panels and aligning the adjacent edge of the panels to form edge-to-edge compression seams, andsecuring the side edges of the fire resistant panels to the support beams after the overlapping side edges of the fire resistant panels have been compressed into the compression gap between adjacent fire resistant panels.

Abstract
An insulated roof structure which has improved fire resistant capabilities is formed on building systems structures by mounting a plurality of purlins (12) on inclined metal rafters (11) and supporting fire resistant panels (32) from the purlins (12). A plurality of support beams (25) are attached to the downwardly facing surface (51) of the purlins (12) and support the fire resistant panels (520. The fire resistant panels (52) are mounted to the support beams (25) and arranged in edge-to-edge contact with one another with the side edges (47) and (48) of adjacent fire resistant panels (52) in sealed engagement with one another.

9. An insulated fire resistant roof structure for a pre-engineered building or the like comprising:
-
a plurality of spaced apart approximately parallel rafter beams; a plurality of approximately equally spaced purlins having upper and lower surfaces with their lower surfaces mounted on said rafters, said purlins being oriented approximately parallel to one another and at right angles to said rafters; sheet metal roofing panels mounted on said purlins; insulating blankets extending between said purlins to resist the transfer of heat through the roof structures; a ceiling structure mounted to the lower surfaces of said purlins for forming an inside ceiling structure including a plurality of fire resistant panels arranged in edge-to-edge contact with one another with the edges of the panels in sealed engagement wedges of their adjacent panels, and means for securing the contacting edges of said panels to said ceiling structure. - View Dependent Claims (10, 11, 12, 13, 14, 16, 17, 18)

15. A fire resistant roof structure of a building, comprising:
-
a plurality of approximately equally spaced parallel purlins having an upper surface and a lower surface; a plurality of hard roofing panels secured to the upper surfaces of said purlins to form an outer roof surface; a plurality of support beams attached to the lower surfaces of said purlins; a plurality of fire resistant panels mounted to said support beams and positioned adjacent one another with the side edges of adjacent fire resistant panels abutting one another; and said panels comprising a compressible composite of fibrous heat insulating material characterized by having been mounted to said support beams with their edges overlapping the edges of adjacent panels and their edges compressed to fit in edge-to-edge abutment with their adjacent panels and forming sealed seams between adjacent panels.
