Abstract: A sheet gripping assembly comprises an elongate member having a side defining inwardly extending wall portions defining confronting channels, and a gripping member of generally zigzag configuration manually manipulable to engage into said confronting channels to secure sheet material between the elongate members and the gripping member. The elongate member may have an elongated slot for positioning therealong a threaded fastener to secure the elongate member to a second structural member.

Abstract: A roof structure having a frame including lower elongate frame members arranged in spaced parallel relation and supporting upper elongate frame members arranged in spaced parallel relation along and extending transverse to the lower members, a roof supported on the upper members, and a condensate collection system for collecting and disposing of condensate running along the underside of the roof including upwardly opening condensate collection channels extending along the upper frame members disposed in condensate collecting relation to the underside of the roof, upwardly opening condensate drainage channels extending along the lower frame members, and means which both secure the frame members to one another at their intersections and conduct condensate from the collection channels to the drainage channels.

Abstract: A roof structure which includes a plurality of first structural members disposed in spaced generally parallel relationship. Each of the first generally parallel members carry an associated roofing material and each has a trough shaped lip disposed proximate to the associated roofing material with the concave face thereof facing the associated roofing material. A plurality of second structural members are disposed in spaced generally parallel relationship and disposed in generally perpendicular relationship to the first structural members. The second structural members each have a trough shaped member having a concave face disposed facing the associated roofing material. The second structural members are each disposed at a lower elevation than at least a part of the first structural members. Structure is provided for directing condensate from the lip of each of the first structural members to at least one of the trough shaped members.
