Claims
- 1. The building system which comprises:
- a roof supporting substructure including a plurality of spaced, parallel beams;
- at least one exterior wall disposed generally along the periphery of the substructure;
- an edge structural member disposed on the substructure having a down-turned flange portion generally aligned with at least one of the exterior walls and set out from a structural web portion;
- a plurality of rectangular roof deck panels spanning transversely across the parallel beams with the ends of at least a portion of the roof deck panels adjacent the edge structural member, each roof deck panel having a chlorosulfonated polyethylene membrane upper surface and a chlorosulfonated polyethylene tongue and groove fastener half extending along each of the four sides of each roof deck panel;
- screw fastener means connecting the opposite edges of the roof deck panels to the spaced parallel beams;
- the fastener halves on adjacent panel edges being engaged over the screw fastener means to form a continuous chlorosulfonated polyethylene membrance except at the junctions of the engaged fastener halves at the corners of the panel members;
- a plurality of flexible chlorosulfonated polyethylene flashing panels each having chlorosulfonated polyethylene tongue and groove fastener halves along at least one edge, the flashing panels being sealingly connected to the roof deck panels disposed adjacent the edge structural member by engaged fastener halves on the panel member and the flashing panel; and
- fascia means having a vertical panel section extending upwardly behind the down-turned flange portion of the edge structural member, the flashing panels extending down around the outer face of the down-turned flange portion and upwardly and inwardly over the upper end of and down behind the panel section of the fascia means, the fascia means extending downwardly to direct water to the exterior face of the wall; and
- screw fastener means extending through the vertical panel section of the fascia to connect the fascia to the building structure.
- 2. The building system of claim 1 wherein all tongue and groove fastener halves on the roof deck panel edges adjacent the edge structual member face downwardly, and the mating fastener halves on the chlorosulfonated polyethylene flashing panel face upwardly.
- 3. The building system of claim 2 wherein the edge structural member includes a horizontal portion resting on the substructure which supports the panels, a vertical riser portion having a height substantially equal to the thickness of the panels, a spacer portion extending outwardly from the riser portion, the depending flange portion extending downwardly from the spacer portion, and the screw fastener means connecting the vertical panel section of the fascia means to the riser portion of the edge structural member.
- 4. The building system of claim 1 wherein:
- there is at least one course of roof deck panels disposed in side-by-side relationship with the ends of all roof deck panels of the one course adjacent an edge structural member;
- a relatively narrow foam insulation filler panel disposed adjacent at least one of the two end roof deck panels of each course; and
- a chlorosulfonated polyethylene flashing panel engaged with the strip fastener half on each end roof deck panel in the course and extending over the filler panel and being flashed to a wall of the building system.
