Substrate with membrane seam plates fixed thereon for precise placement of seam plates on roof decking assemblies

摘要

A seam plate or membrane plate implement assembly comprises a support strip or substrate having a longitudinal extent and upon which a plurality of seam plates or membrane plates are fixedly disposed at predetermined uniformly spaced longitudinal positions which correspond to the transverse spacing defined between the crest portions of an underlying corrugated roof decking substructure. In this manner, when a particular one of the membrane plates or seam plates is fixedly secured to one of the crest portions of the underlying corrugated roof decking substructure by suitable threaded fasteners, the remaining membrane plates or seam plates will be automatically properly aligned with the other crest portions of the underlying corrugated roof decking substructure so as to automatically ensure proper and secure fixation of the seam plates or membrane plates upon the roof decking assembly. When the seam plate or membrane plate implement assembly is used with a non-corrugated roof decking substructure, the seam plates or membrane plates are disposed at predeterminedly spaced locations upon the substrate so as to provide the environmental membranes with sufficient uplifting force resistance.
