Abstract: The present invention provides an apparatus and a method for insulating a covered patio by supporting insulation upon ceiling panels depending from clamps engaged in the apices of a twin-vee roof. The roof engaging elements of the clamp include a diagonal face plate with a gripping extended edge and a set screw threadedly engaged through said diagonal face plate. These elements are disposed so that the gripping edge of the diagonal plate and the leading edge of the set screw engage opposite vertical faces of the receiving slot at an apex of a roofing panel. The head of the set screw is accessible when the clamp is in place and tightening the set screw secures the clamp to the roofing panels and lodges the clamp in place by establishing sufficient force to the opposing walls adjacent the closed top of the slot. The depending end of the clamp carries mean of connection with the ceiling panels and this connection establishes the cavity into which the insulation is placed.

Abstract: A panel mounting clip assembly is adapted to connect the intermediate longitudinal ribs of panel members and the rib-like joints between adjacent ones of the panel members to panel support members. The clip assembly comprises a base member that is fastened to the panel support member and a top clip that is frictionally engaged with interior surfaces of the ribs or joints to accommodate thermal expansion and contraction of the panels. The top clip-to-base member connection provides for movement of the top clip transversely of the length of the panel member thereby to accommodate rib-to-clip and joint-to-clip misalignments. The top clip-to-base member connection also provides for limited universal movement of the top clip relative to the base member to accommodate any inherent minor distortions in the profile of the intermediate ribs or the panel elements of the rib-like joint. A roof or wall structure utilizing the panel mounting clip assembly is described.
