A seam plate implement assembly comprises a substrate having a longitudinal extent and upon which a plurality of seam 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 is fixedly secured to one of the crest portions of the underlying corrugated roof decking substructure by suitable threaded fasteners, the remaining membrane 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 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 are disposed at predeterminedly spaced locations upon the substrate so as to provide the environmental membranes with sufficient uplifting force resistance. The substrate may have a C-shaped or V-shaped cross-sectional configuration for enveloping each one of the seam plates, or may comprise a mesh member through which prong members of the seam plates are extended and folded so as to secure the seam plates upon the substrate.

Abstract Cette demande de brevet décrit un module d'installation de plaques de fixation de membrane étanche comportant une lisière supportant plusieurs plaques de fixation disposées à intervalles réguliers, et dont l'espacement correspond à celui des nervures des panneaux de couverture ondulés sous-jacents. De la sorte, lorsqu'une des plaques est fixée solidement à l'une des nervures d'un panneau ondulé à l'aide d'une attache filetée, les autres plaques de fixation sont automatiquement alignées avec les autres nervures du panneau de couverture ondulé, ce qui permet d'attacher solidement les plaques de fixation aux panneaux ondulés sous-jacents. Ce module d'installation de plaques de fixation peut aussi être utilisé sur des panneaux de couverture unis (sans nervures). Les plaques de fixation sont alors disposées à des points prédéterminés sur le substrat afin d'offrir une résistance suffisante aux efforts exercés sur la membrane étanche. Le substrat peut présenter un profil en C ou en V afin d'envelopper chaque plaque de fixation, ou comporter une couche de matériau maillé que la tige de retenue de la plaque de fixation peut traverser avant d'être recourbée dans le but d'attacher solidement la plaque au substrat.
