Self-stick metal plate and method of applying the same

Abstract

A coated metal plate is provided as a mechanical fastening device for a roof deck. The top side of the metal plate can have a coated layer, and the bottom side of the metal plate has an adhesive layer. The adhesive layer is covered by a film, which is removable and can be peeled off at the time of installation. The bottom side of the metal plate is attached to the roof deck by the adhesive layer, and a roofing membrane is heat welded to the coated top side of the metal plate. The disc shaped metal plate can have a hole in the center of the plate, and a fastening device such as a screw can extend through the hole and attach the metal plate to the roof deck for additional support.

1 . A mechanical fastener for a roofing structure, comprising: 
 a metal plate, the metal plate having a top side and a bottom side; and    an adhesive layer on the bottom side of the metal plate.    
     
     
         2 . The mechanical fastener for a roofing structure of  claim 1 , further comprising: 
 a coated layer on the top side of the metal plate.    
     
     
         3 . The mechanical fastener for a roofing structure of  claim 1 , further comprising: 
 a removable film covering the bottom of the metal plate having the adhesive layer.    
     
     
         4 . The mechanical fastener for a roofing structure of  claim 1 , wherein the metal plate is disc shaped.  
     
     
         5 . The mechanical fastener for a roofing structure of  claim 1 , wherein said adhesive of the adhesive layer is selected from the group consisting of a butyl compound or other waterproofing compound such as single component PVAc (polyvinyl acetate) water-resistant adhesive, water-resistant polyvinyl acetate adhesive, EVA (ethylene vinyl acetate)-hot melt adhesives, pressure sensitive hot melt adhesive atactic polypropylene (APP) base pressure sensitive tapes, polyurethane adhesives, thermoplastic adhesive film based with co-polyamides, thermoplastic adhesive film based with mixed polyolefin and co-polyamide, animal base adhesive, asphaltic base adhesive styrol or verstat acrylate types, and neoprene rubber cementic base adhesive.  
     
     
         6 . The mechanical fastener for a roofing structure of  claim 1 , further comprising: 
 a hole at the center of the metal plate extending from the top side to the bottom side of the metal plate.    
     
     
         7 . The mechanical fastener for a roofing structure of  claim 6 , further comprising: 
 a fastening device provided through the hole.    
     
     
         8 . The mechanical fastener for a roofing structure of  claim 7 , wherein the fastening device comprises a screw.  
     
     
         9 . A method of applying a mechanical fastener to a roof deck, the method comprising: 
 peeling a film off a bottom side of a metal plate, the bottom side having an adhesive layer; and    attaching the bottom side of the metal plate having the adhesive layer onto a roof deck.    
     
     
         10 . The method of applying a mechanical fastener to a roof deck of  claim 9 , the method further comprising: 
 heat welding a roofing membrane on a coated top side of the metal plate and the roof deck.    
     
     
         11 . The method of applying a mechanical fastener to a roof deck of  claim 9 , the method further comprising: 
 fastening a fastening device through the metal plate and into the roof deck.    
     
     
         12 . The method of applying a mechanical fastener to a roof deck of  claim 11 , wherein the fastening device extends through a hole provided at the center of the metal plate.  
     
     
         13 . The method of applying a mechanical fastener to a roof deck of  claim 9 , wherein the metal plate is disc shaped.
