Decking for receipt of skylights

An adaptor for securing a skylight to a roof deck comprising:

• a first section having a first axially-extending body, said first body having an inner surface and an outer surface, said inner surface of said first body defining a first cavity, said first body having a first outwardly-extending radial flange extending away from said first cavity;
• and
• a second section having a second axially-extending body, said second body having an inner surface and an outer surface, said inner surface of said second body defining a second cavity, said second body having a second outwardly-extending radial flange extending away from said second cavity,
• wherein said first body and said second body are attached to each other so that a tube receiving recess is defined by said inner surface of said first body and said second body, and a panel receiving recess is defined by said first flange, at least a portion of said outer surface of said first body, and at least a portion of said outer surface of said second body.

A roofing assembly for securing a skylight to a roof structure, said roofing assembly comprising:

• a profiled deck plate defining a peripheral edge having a first surface and a second surface;
• a plurality of laterally-spaced, longitudinally-extending protruding ribs defining a portion of said plate, each of said ribs includes spaced apart sidewalls connected to a top wall, said ribs extending from a first end of said plate to a second end of said plate, said sidewalls and said top wall of each rib defining a recessed area on said first surface of said plate;
• a spacer separating each rib on said plate;
• a passageway defined on said plate;
• and
• an adaptor comprising a hollow open-ended body having an inner surface and an outer surface, said body having a first end and a second end, said inner surface of said body defining a cavity, a first flange attached to said first end of said body and extending radially outwardly away from said cavity, and a second flange attached to said second end of said body and extending radially outwardly away from said cavity, wherein said body of said adaptor passes through said passageway, said first flange is attached to said first surface of said profiled deck plate and said second flange is attached to said second surface of said profiled deck plate.

A method for mounting a skylight in a roof structure comprising the steps of:

• a) providing a profiled deck plate defining a peripheral edge having a first surface and a second surface, said deck plate comprising a plurality of laterally-spaced, longitudinally-extending protruding ribs defining a portion of said plate, each of said ribs includes spaced apart sidewalls connected to a top wall, said ribs extending from a first end of said plate to a second end of said plate, said sidewalls and said top wall of each rib defining a recessed area on said first surface of said plate, a spacer separating each rib on said plate, and a passageway defined on said plate;
• b) providing an adaptor comprising a hollow open-ended body having an inner surface and an outer surface, said body having a first end and a second end, said inner surface of said body defining a cavity, a first flange attached to said first end of said body and extending radially outwardly away from said cavity, and a second flange attached to said second end of said body and extending radially outwardly away from said cavity;
• c) forming a passageway through said profiled deck plate;
• d) securing said adaptor to said profiled deck plate through said passageway;
• and
• e) installing a skylight through said adaptor in said profiled deck plate.
