Method and apparatus for applying sheet material to a roof structure

Apparatus for applying sheet material to roof structures or the like which include a plurality of purlins in spaced substantially parallel relationship comprising a framework for mounting on and extending across the purlins, guide means for guiding said framework along the lengths of the purlins, first and second reel support means mounted on said framework with said first reel support means for supporting reels of sheet material at alternate ones of the spaces between adjacent ones of the purlins positioned on one side of said framework and said second reel support means for supporting reels of sheet material at the other ones of the spaces between adjacent ones of the purlins positioned on the other side of said framework, and a worker's platform on the framework, said worker's platform extending between said first and second reel support means.

Apparatus for applying sheets of insulation material or the like to roof structures of buildings of the type including a plurality of purlins arranged in spaced substantially parallel relationship with respect to one another comprising a support framework for mounting on and extending across the purlins, guide means for guiding said support framework along the purlins, said support framework including a first plurality of reel supports for supporting reels of sheet insulation material over alternate spaces between the purlins and a second plurality of reel supports for supporting reels of sheet insulation material over the other alternate spaces between the purlins, said second plurality of reel supports being displaced rearwardly along the purlins from said first plurality of reel supports, and a worker's platform extending between said first plurality of reel supports and said second plurality of reel supports, said framework defining passages beneath said worker's platform for the movement therethrough of the sheets of insulation material.

Apparatus for applying sheet material or the like to roof structures of the type including a plurality of purlins arranged in spaced substantially parallel relationship with respect to one another comprising a support framework for mounting on and extending across the purlins of a roof structure, guide means connected to said support framework for guiding said support framework along the purlins, and a worker's platform supported by said support framework, and support framework including means for supporting reels of sheet material over the spaces between adjacent ones of the purlins and for paying out the sheet material into the spaces between adjacent ones of the purlins.

In a roof structure comprising a plurality of purlins each including an upwardly extending central web, said purlins being mounted in spaced parallel relationship with respect to one another, the improvement therein of the upwardly extending central webs of said purlins defining a plurality of openings therein at various heights in the webs of said purlins and with the openings of each purlin being in approximate alignment with the openings of the purlins on opposite sides thereof, and a plurality of insulation support straps oriented parallel to one another and perpendicular to said purlins and extending through the aligned openings of said purlins, elongated sheets of material of a width approximately equal to the spacing between the central webs of said purlins positioned between and extending parallel to said purlins and resting on said support straps, sheets of roofing material mounted on said purlins and extending over said sheets of material, and loose insulating material supported by said sheets of material.

A method of applying a roof to a building of the type including inclined parallel rafters and a plurality of purlins with upwardly extending central webs and oppositely extending upper and lower flanges mounted on and extending across the rafters comprising extending support means between adjacent ones of the purlins at a level above the lower flanges of the purlins, supporting reels of elongated sheets of the material on the purlins, moving the reels along the purlins and paying out the sheet material from the reels down between the purlins and on said insulation support means as the reels are moved along the purlins with the lengths of the sheets extending parallel to the purlins, placing loose insulation material on the sheets, and applying hard roofing material to the purlins over the loose insulation material.

A method of insulating a roof structure on a building of the type including a plurality of parallel purlins comprising mounting a platform on the purlins, supporting reels of elongated sheet material on the platform, simultaneously moving the platform along the purlins and paying out sheet material from the reels supported on the platform to spaces between adjacent ones of the purlins, placing loose insulation material on the sheets of material, and applying hard roofing material to the purlins.
