The present invention relates generally to roof curb systems and methods. More particularly, this invention pertains to systems and methods for securing multiple roof accessories to roofs with roof curbs.
Prior art curb mounted roof accessories (e.g., skylights and smoke vents) are attached to roofs in singular fashion on individual roof curbs because attachment to one another violates the fastening requirements specified by most unit manufacturers. For architects that seek linear arrangements of multiple units to achieve a strip of natural daylight into a space or a reduction in the quantity of roof penetrations, attachment of the roof accessories or units to roof curbs is compromised because fastening clearances are eliminated by the abutment of unit frames. The existing plate and baton method of attachment is cumbersome as meticulous welding often warps thin metal frames of the roof accessories at critical water-tight points compromising the durability and weather-tightness of the units as designed by the manufacturer. Therefore, such installations are prone to leaking and must be thoroughly sealed with mastic of caulk, which degrades relatively quickly.
Aspects of the invention provide linking devices for roof accessories (e.g., skylights and smoke vents) installed on roofs with roof curb systems. They may be largely metallic and are designed to provide a weather tight seal between a pair of roof accessories while negating uplift imposed by external forces (e.g., high winds) on roof curb mounted skylights and/or smoke vents arranged in multiple, connected unit configurations. The accessories are linearly linked through a unique gutter assembly that is attached to a pair of roof curbs and includes a clamping member (e.g., uplift channel or cap) to provide uniform clamping that withstands uplift pressures. No modifications are needed to unit frames (i.e., accessory frames) and the ability of traditional roof curb mounted skylights and/or smoke vents to resist uplift is restored.
In one aspect, a gutter channel assembly for mounting roof accessories to a roof having a pair of longitudinally extending roof curbs includes a gutter and and uplift channel. The gutter is configured to extend laterally between the pair of roof curbs of the roof and to receive a longitudinal end of each roof accessory of a pair of roof accessories when the gutter channel assembly is installed on the roof. The uplift channel is configured to secure to the gutter and extend at least partially over the longitudinal ends of the pair of roof accessories received in the gutter when the gutter channel assembly is installed on the roof.
In another aspect, a method of installing a gutter channel assembly on a roof having a pair of longitudinally extending roof curbs include securing opposing lateral ends of the gutter of the gutter channel assembly to the pair of roof curbs. Longitudinal ends of a pair of roof accessories are placed between a pair of opposing sides of the gutter. A hole through an uplift channel is then placed over a threaded rod extending upwardly from the gutter such that longitudinal ends of the uplift channel extend at least partially over the longitudinal ends of the roof accessories received in the gutter. A nut of the gutter channel assembly is screwed onto the threaded rod to secure the uplift channel to the gutter channel and the roof accessories within the gutter.

In the embodiment of
In one embodiment, the gutter uplift channel assembly 100 includes roof curb gutter 102 and uplift channel 104 which attach to one another with an offset to accommodate specific skylight and/or smoke vent frame dimensions which may vary among unit manufacturers. The roof curb gutter 102 and uplift channel 104 may be made of metal, vinyl, or some other material such as a polymer. The roof curb gutter 102 is attached to roof curbs 300 and extends laterally between the roof curbs 300. The skylights and/or smoke vents 200 being placed adjacent one another in a row or column are set onto the roof curb gutter 102 such that any water shed from the end 202 of the skylight and/or smoke vent 200 is directed into the gutter 102 and laterally outward past the roof curbs 300 that the roof curb gutter 102 extends between. The uplift channel 104 applies downward force to the frames (of the adjacent skylights and/or smoke vents) to maintain the ends 202 of the adjacent skylights and/or smoke vents 200 in the roof curb gutter 102 and resist uplift in high wind situations. In one embodiment, at least one (e.g., a pair of) threaded rods 106 extend upwardly from the gutter 102, and through corresponding hole(s) 108 in the uplift channel 104. A nut 110 (e.g., wing nut) secures the uplift channel 104 to the threaded rods 106 (e.g., bolts) and thus to the roof curb gutter 102.
In one embodiment, the uplift channel 104 is a formed hat channel shape specifically designed with clearances to allow consistent alignment with the skylight and/or smoke vent frames 202 to the roof curb 300 through the applied downward force when fastened to the roof curb gutter 102 via the one or more threaded rods (e.g., bolts) 106. The recessed center section of the uplift channel 104 with pre-punched holes 108 coordinating with the gutter 102 through bolts 106 is dimensioned to provide the applicable strength for uniform pressures to be applied via the through bolt attachment depicted within
In one embodiment, the roof curb gutter 102 portion of the assembly 100 is designed to nest and attach via the pre-punched holes to the modified roof curb wall 300 that adjoins the skylights and/or smoke vents 200. The roof curb gutter 102 seals appropriately to the roof curb 300 and roofing material (e.g., sidewalls) dependent on the construction roofing type with applicable construction sealants, and fastens via structural screws, rivets, or welds with its longitudinal positioning based on the skylight and/or smoke vent 200 unit length to provide the bearing point for the adjacent unit (i.e., roof accessory) frames.
In one embodiment, the through bolt 106 attachment is integrated to the roof curb gutter 102. A threaded bolt 106 is fastened to a top of the gutter 102 bottom 420 trough via mechanical attachment to provide adequate support to resist uplift forces. The gutter 102 is not limited solely to this curb wall application, installation procedure, or attachment method.
