Abstract: Support structure for holding a plurality of roof panels during assembly of a standing seam roof on a prefabricated building including a spacer block having an elongated body with predetermined shaped ends thereon. In one embodiment one end is of square configuration and the other end is of compound tapered configuration. In another embodiment the end of square configuration is provided with a projecting tenon thereon for positive engagement with inside flanges of a roof panel yoke fastening/retainer clip. In a modification of this embodiment, pre-formed notches or recesses are provided for ease in installation of this end with the roof panel fastening/retainer clip. The other end of the spacer block having a pointed configuration may be of compound tapered form, conical form, semi-elliptical or oval form, or a combination of these described shapes. Also, the end may be completely rounded or semi-rounded with a blunt tip.

Abstract: A clip unit for attaching a standing seam roof to a building structural element includes a base with a cross-piece mounted thereon. A one-piece tab is slidably mounted on the cross-piece and is interfolded into the standing seam used to attach two roof panels together to attach those panels to the clip unit. The base is attached to a building structural element, such as a purlin, or the like, so that the roof panels are attached to that structural element in a manner which permits thermally induced panel movement to be accommodated. Another embodiment has a tab integral with a base which has a rod therewith which rod in turn is slidable along an eyebolt which is attached to a building structural element.
