Skylight structures or the like wherein the supporting and supported structural members defining the metal framework including flange formations upon which glass panels are secured are provided with longitudinally extending drainage channel formations and wherein the open ends of the drainage channel formations of the supported structural members intersect and overlap the drainage channel formations of the supporting structural members to the extent that water collected therein is discharged into the drainage channel formations of the supporting structural members at a point remote from the intersections thereof and wherein the structural members are interconnected by displaceable clamping means carried by said overlapping ends including a clip embracing same from below in the region of overlap and upon displacement upwardly engage the flange formations of the suporting structural members from below.

In a roof structure, a plurality of rafters arranged in inclined substantially uniformly spaced apart relation and provided with a plurality of opposed recess means therein at uniformly spaced apart intervals therealong and a plurality of purlins extending therebetween with the ends thereof projecting into and fully registered within said opposed recess means of said rafters so as to intersect therewith and be supported therefrom, each said purlins and rafters including longitudinally extending open ended drainage channel means therein and opening upwardly longitudinally centrally therealong, said drainage channel means being defined by a bottom wall upstanding spaced apart outer side walls and flange means extending inwardly from said outer side walls and in spaced apart opposed overlying relation to said bottom wall, each said recess means of said rafters having a perimetral extent within said side walls and flanges means thereof and the respective depths of the channel means of said purlins and rafters being such that in full registration said intersecting flange means of said purlins and rafters are disposed in substantially coplanar relation and water collected in the channel means of said purlins is discharged therefrom downwardly into the channel means of said rafters at a point inwardly spaced form the side walls of said rafters and connecting means carried by said purlins at the ends thereof for engagement with said channel means of said rafters for securing said purlins and rafters against separation.
