Deck panel and fastening system

A roof deck comprising:

• a plurality of roof panels, each roof panel having an inner skin and an outer skin;
• each roof panel comprising an insulation layer between and bonding with the inner and outer skin, each roof panel defining a longitudinal axis, and mating longitudinal edges with a tongue and groove configuration, adjacent roof panels mating together along the tongue and groove longitudinal edges to prevent independent movement of the adjacent roof panels with respect to one another;
• a first plurality of fasteners, the first plurality of fasteners securing the adjacent roof panels together along the longitudinal edges, the first plurality of fasteners are spaced from each other along the longitudinal edges at a distance apart from about four to 24 inches on center;
• a second plurality of fasteners, the second plurality of fasteners securing the plurality of roof panels directly to and only to a truss forming a roof framework, the second plurality of fasteners are spaced from each other transverse to the longitudinal axis at a distance apart from one another of about four to 10 inches on center;
• a plurality of washers, one washer of the plurality is coupled with a respective one of the second plurality of fasteners, the plurality of washers each having a diameter of about one-half inch to about three inches enabling force distribution from the second plurality of fasteners onto the outer skin prohibiting countersinks into the panel;
• a membrane covering the plurality of roof panels and the roof deck provides a diaphragm shear of 717 to 1903 PLF due to only being secured directly with the truss.

A building structure comprising:

• a frame having a roof, a plurality of side walls;
• enclosing the frame;
• the roof further comprising a plurality of roof panels, each roof panel having an inner skin and an outer skin;
• each roof panel comprising an insulation layer between and bonding with the inner and outer skin, each roof panel defining a longitudinal axis and mating longitudinal edges with a tongue and groove configuration, adjacent roof panels mating together along the tongue and groove longitudinal edges;
• a first plurality of fasteners, the first plurality of fasteners securing the adjacent roof panels together along the tongue and groove longitudinal edges to prevent independent movement of the adjacent roof panels with respect to one another, the first plurality of fasteners are spaced from each other along the longitudinal edges at a distance apart from about four to 24 inches on center;
• a second plurality of fasteners, the second plurality of fasteners securing the plurality of roof panels directly to and only to the frame of the roof forming a roof framework, the second plurality of fasteners are spaced from each other transverse to the longitudinal axis at a distance apart from one another of about four to 10 inches on center;
• a plurality of washers, one washer of the plurality is covered with a respective one of the second plurality of fasteners, the plurality of washers each having a diameter of about one-half inch to about three inches enabling force distribution from the second plurality of fasteners onto the outer skin prohibiting countersinks into the panel;
• a membrane covering the plurality of roof panels and the roof deck provides a diaphragm shear of 717 to 1903 PLF due to only being secured directly with the frame.
