Abstract
A roof panel joint construction and clip device for use therein to secure abutting edges of panels so that the clip and associated fastener is concealed and so that the panels are capable of expanding or contracting longitudinally due to thermal changes. Abutting edges of roof panels are crimped together with a lip portion of the clip positioned therebetween while the clip is secured to a purlin with a flange portion of the clip including an elongated slot and a spring clamping member positioned between the head of a fastener and the flange.
Claims18
A device for securing abutting edges of roof panels to each other and to a supporting structure in a concealed manner and to permit expansion and contraction of the roof panels, the assembly comprising a clip member including a base flange portion and lip portion interconnected by an upstanding web portion, an elongate slot formed in the base flange, a spring member preassembled to the flange of the clip member and over the elongate slot, the spring member having an arched configuration providing a pair of spaced elongated flange abutting edges and a crest portion intermediate said edges, an aperture formed through the crest portion of the spring, tubular means extending through the elongate slot assembling the spring to the base in a compressed condition while allowing the clip member to move relative to the spring in the direction of the elongate slot, the clip and the tubular means adapted to receive a fastener member extending through the aperture and the elongate slot to secure the clip to a support structure while allowing limited relative movement between the clip and the support structure.
A device for securing abutting edges of roof panels to each other and to supporting structure in a concealed manner, the assembly comprising a clip member including a base flange portion and lip portion interconnected by an upstanding web portion, an elongate slot formed in the base flange, a clamping spring member preassembled to the clip member over the longate slot, the spring member having an arched configuration providing a pair of spaced flange abutting edges and a crest portion intermediate said edges, an aperture formed through the crest, means on the clip member locating, temporarily retaining and centering the aperture of the spring member over the elongated slot, means to preassemble the spring member over the base flange portion wherein the clip member is capable of limited movement relative to the spring member after the influence of the temporary centering means is overcome.
A panel joint construction including first and second panel units with abutting side edges each having an upstanding web portion terminating in interlocking lip portions, a supporting purlin structure, at least on discrete integral clip member having a base flange, upstanding web portion, and lip portion, the clip member being adapted to be positioned between the abutting edges of the panel units with the base flange of the clip juxtaposed over the purlin structure, an elongate slot formed in the base flange, an arched spring member juxtaposed over the base flange, an aperture in the spring member aligned with at least a portion of the elongate slot and a threaded fastener extending through the aperture, elongated slot and into the purlin to clamp the clip against the purlin in such a manner as to permit selective movement of the clip relative to the purlin and responsive to changes in dimensions of the panel units due to temperature changes.
A device for securing abutting edges of roof panels to each other and to a supporting structure in a concealed manner, the device comprising a clip member including a base flange portion and lip portion interconnected by an upstanding web portion, an elongate slot formed in the base flange, a clamping member juxtaposed over the base flange portion, the clamping member having a configuration providing a pair of spaced flange abutting longitudinal edges, one such longitudinal edge positioned substantially at the line of juncture between the web portion and base flange, an aperture formed through the clamping member in alignment with the elongate slot, means to preassemble the clamping member over the base flange portion retaining the clamping member thereon, means on the clip member locating, temporarily retaining, and centering the aperture of the clamping member over the elongate slot wherein the device is adapted to be secured to a supporting structure through the use of a threaded fastener extending through the aperture so that the clip member is capable of limited movement relative to the clamping member after the influence of the temporary centering means is overcome.
