Abstract
A prefabricated sawtooth roof assembled from a plurality of roof modules houses solar energy collector panels which comprise a part of a solar energy collector system wholly enclosed within a building envelope. Each roof module comprises a glazed, insulated, watertight unit and may also include other shop installed mechanicals such as plumbing, heating, ventilating, lighting and electrical equipment. Each roof module has at least one structurally hinged panel section which is collapsed for highway transportation and pivoted to erection position as the module is hoisted from its carrier to the top of a building wall or other supporting structure.

- 2. A roof structure comprising a truss assembly including a plurality of horizontally extending truss beams and a plurality of braces extending between and connecting said truss beams in laterally spaced parallel relation, and a horizontally elongated roof panel assembly supported on said truss assembly and including a first roof panel section supported in an upwardly inclined position, a generally horizontally disposed rain trough-walkway supported on said truss assembly and connected to said first roof panel section, said rain trough-walkway having a generally U-shaped cross section and including a downwardly pitched bottom wall and a pair of laterally spaced side walls extending upwardly from said bottom wall, and a second roof panel section connected to the upper end of said first roof panel section to pivot relative thereto about a horizontal axis between a first position wherein it depends in a generally vertically disposed position from said first roof panel section and a second position wherein it extends generally laterally outwardly from said first roof panel section.
- 16. A sawtooth roof module comprising a truss assembly including a pair of horizontally extending truss beams and a plurality of cross braces extending between the connecting said truss beams in laterally spaced parallel relation, and a horizontally elongated roof panel assembly supported on said truss assembly and including a first roof panel section supported in an upwardly inclined position and having its upper end disposed generally above one of said truss beams, a second roof panel section connected to the upper end of said first roof panel section to pivot relative thereto about a horizontal axis between a first position wherein it depends in a generally vertically disposed position from said first roof panel section and a second position wherein it extends generally laterally outwardly and downwardly from said first roof panel section, a generally horizontally disposed rain trough-walkway supported on said truss assembly and having a generally U-shaped cross section, said rain trough-walkway having a generally horizontally disposed bottom wall pitched downwardly in at least one direction and a pair of opposing laterally spaced apart side walls, one of said side walls being connected at its upper edge to the lower edge of said first roof panel section, and a third roof panel section connected to the upper edge of the other of said side walls and upwardly and laterally outwardly inclined therefrom, said third panel section being connected at its upper end portion to a upper horizontally extending portion of the other of said truss beams.
- 21. A method for making a roof structure for a building comprising the steps of fabricating a roof module having a roof panel assembly including an upwardly inclined first roof panel section and a second roof panel section having one end portion pivotally connected to the upper end portion of said first roof panel section, pivoting said second roof panel section to a generally vertically depending position relative to said first roof panel section, transporting said roof module to a building site with said second roof panel in its depending position, pivoting said second roof panel section from its depending position to a laterally outwardly extending position relative to said first roof panel section, lifting said roof module into position on a partially erected building, and fastening the end portion of said second panel assembly opposite said one end in its laterally outwardly extending position to a roof panel section comprising a part of another roof module of like kind.
- 23. A method for making a roof structure for a building comprising the steps of fabricating a roof module having a roof panel assembly including a plurality of roof panel sections, pivotally connecting one end portion of one of said panel sections to the upper edge of another of said panel sections to pivot about a generally horizontal axis, pivoting said one panel section laterally inwardly relative to said other panel section and to a traveling position to reduce the lateral width of said roof module, transporting said roof module to a building site with said one panel section in its traveling position, pivoting said one panel section from its traveling position to a laterally outwardly extending position relative to said other panel section while simultaneously lifting said roof module into position on a partially erected building, and fastening said one panel section in its laterally outwardly extending position after said roof module has been lifted in position.
-
25. A method for making a roof structure for a building comprising the steps of fabricating a roof module having a roof panel assembly including an upwardly inclined first roof panel section and a second roof panel section having one end portion pivotally connected to the upper end portion of said first roof panel section, pivoting said second roof panel section to a generally vertically depending position relative to said first roof panel section, transporting said roof module to a building site with said second roof panel in its depending position, pivoting said second roof panel section from its depending position to a laterally outwardly extending position relative to said first roof panel section, lifting said roof module into position on a partially erected building, said steps of pivoting said second roof panel section to a laterally outwardly extending position and lifting said roof module being performed simultaneously, and fastening said second panel assembly in its laterally outwardly extending position.
