Method of assembling skylight structures

Claim 1

A method of assembling a skylight structure having purlins with integral condensate channels thereon joined to rafters having integral condensate channels thereon, said rafter having notches therein in a framework supporting glazing panels and providing a condensate removal system, said purlins having projecting ends thereon, said method comprising the steps of: assembling a plurality of rafters in predetermined and fixed positions relative to one another with said notches facing upwardly and at distances to be spanned within said projecting ends at which positions the rafters will remain during and after further assembling of the skylight strUcture, lowering the purlins directly down onto upwardly facing notches of said rafters at predetermined longitudinally spaced positions along each pair of adjacent rafters to span the same with glazing supporting portions of said purlins facing upwardly, resting curbs projecting from each end of the purlins onto upwardly facing notches of the rafters with said upwardly facing glazing supporting portions aligned to support a glazing panel and simultaneously forming said condensate drainage system with the ends said integral condensate channels in said purlins being superimposed over the integral condensate channels in said rafters to form said condensate removal system without adding additional separate condensate gutters therebetween, interlocking each of the purlins to its supporting rafters with condensate channels in the purlins extending into said projections and superposed over condensate channels in the rafters for discharging condensate to the latter, lowering glazing panels onto said upwardly facing portions of said rafters and purlins, and securing glazing panels in said purlin and rafter framework to fabricate said skylight structure having a condensate removal system.

Claim 2

A method of assembling a skylight structure having purlins with integral condensate channels thereon joined to rafters having integral condensate channels thereon, said rafter having notches therein in a framework supporting glazing panels and providing a condensate removal system, said purlins having projecting ends thereon, said method comprising the steps of: assembling a plurality of rafters in predetermined and fixed positions relative to one another with said notches facing upwardly and at distances to be spanned within said projecting ends at which positions the rafters will remain during and after further assembling of the skylight strUcture, lowering the purlins directly down onto upwardly facing notches of said rafters at predetermined longitudinally spaced positions along each pair of adjacent rafters to span the same with glazing supporting portions of said purlins facing upwardly, resting curbs projecting from each end of the purlins onto upwardly facing notches of the rafters with said upwardly facing glazing supporting portions aligned to support a glazing panel and simultaneously forming said condensate drainage system with the ends said integral condensate channels in said purlins being superimposed over the integral condensate channels in said rafters to form said condensate removal system without adding additional separate condensate gutters therebetween, interlocking each of the purlins to its supporting rafters with condensate channels in the purlins extending into said projections and superposed over condensate channels in the rafters for discharging condensate to the latter, lowering glazing panels onto said upwardly facing portions of said rafters and purlins, and securing glazing panels in said purlin and rafter framework to fabricate said skylight structure having a condensate removal system.

Claim 3

A method of assembling a skylight structure having closed tubular purlins with integral condensate channels on the upper portions thereof joined to rafters with integral condensate channels on the upper portions thereof and having notches therein in a framework supporting glazing panels and providing a condensate removal system, said purlins having projecting end portions thereon, said method comprising the steps of: assembling at least three rafters in predetermined and fixed parallel positions relative to one another each with said notches facing upwardly and at distances to be spanned by said projecting ends with inner ones of said rafters having pairs of opposed pairs of notches for supporting ends of pairs of purlins adjacent each other and at which positions the rafters will remain during and after further assembling of the skylight structure, lowering onto a first pair of said rafters a series of purlins spaced longitudinally of the rafters without spreading the first rafter pair with the projecting end portions of each of the purlins of the series directly down into said upwardly facing notches of said rafters at predetermined longitudinally spaced positions along said first pair of rafters to span the same with glazing supporting portions of said purlins facing upwardly, resting said end portions projecting from each end of the purlins onto upwardly facing notches of the rafters with said upwardly facing glazing supporting portions aligned to support a glazing panel and simultaneously superimposing the integral condensate channels in said end portions of said purlins over the integral condensate channels in said rafters without spreading said rafters thereby forming said condensate removal system, without spreading an adjacent third rafter and without spreading an adjacent rafter which was one of said first pair of rafters lowering a series of purlins into the notches of this common center rafter and said third rafter with said purlins in each series being aligned, interlocking each of the purlins to its supporting rafters with condensate channels in the purlins extending into said ends thereof and superposed over condensate channels in the rafters for discharging condensate to the latter by pins extending horizontally and vertically between the ends of the purlins and into portions of the rafters to interlock the purlins and rafters with hidden pins, lowering glazing panels onto said upwardly facing portions of said rafters and purlins, and securing glazing panels in said purlin and rafter framework to fabricate said skylight structure having a condensate removal system.

Claim 4

A method of assembling a skylight structure having closed tubular purlins with integral condensate channels on the upper portions thereof joined to rafters with integral condensate channels on the upper portions thereof and having notches therein in a framework supporting glazing panels and providing a condensate removal system, said purlins having projecting end portions thereon, said method comprising the steps of: assembling at least three rafters in predetermined and fixed parallel positions relative to one another each with said notches facing upwardly and at distances to be spanned by said projecting ends with inner ones of said rafters having pairs of opposed pairs of notches for supporting ends of pairs of purlins adjacent each other and at which positions the rafters will remain during and after further assembling of the skylight structure, lowering onto a first pair of said rafters a series of purlins spaced longitudinally of the rafters without spreading the first rafter pair with the projecting end portions of each of the purlins of the series directly down into said upwardly facing notches of said rafters at predetermined longitudinally spaced positions along said first pair of rafters to span the same with glazing supporting portions of said purlins facing upwardly, resting said end portions projecting from each end of the purlins onto upwardly facing notches of the rafters with said upwardly facing glazing supporting portions aligned to support a glazing panel and simultaneously superimposing the integral condensate channels in said end portions of said purlins over the integral condensate channels in said rafters without spreading said rafters thereby forming said condensate removal system, without spreading an adjacent third rafter and without spreading an adjacent rafter which was one of said first pair of rafters lowering a series of purlins into the notches of this common center rafter and said third rafter with said purlins in each series being aligned, interlocking each of the purlins to its supporting rafters with condensate channels in the purlins extending into said ends thereof and superposed over condensate channels in the rafters for discharging condensate to the latter by pins extending horizontally and vertically between the ends of the purlins and into portions of the rafters to interlock the purlins and rafters with hidden pins, lowering glazing panels onto said upwardly facing portions of said rafters and purlins, and securing glazing panels in said purlin and rafter framework to fabricate said skylight structure having a condensate removal system.
