Parapet wall closure

Abstract

A wall closure for a vertical wall or parapet on a roof structure is fabricated as an integral unit from a non-corrosive, durable material. The wall closure includes an anchoring flange for attachment to a top end of the wall, upper flanges defining a mounting base for attachment of a wall coping, an intermediate portion between the anchoring flange and the upper flanges creating depth therebetween for ventilation of the roof system, and opposite side panels extending down from the upper flanges for overlapping attachment to the opposite sides of the wall, thereby enclosing the top end of the wall. The lower ends of the side walls are angled outwardly to provide added rigidity and strength to the wall closure.

1 . A wall closure for installation over the top end of a vertical wall on a roof structure, wherein the vertical wall includes a top surface and opposite side surfaces;
 said wall closure comprising:   an integral, one-piece body comprising:
 a central longitudinal anchoring flange for mating attachments to the top surface of the vertical wall; 
 first and second longitudinal upper flanges on opposite sides of said anchoring flange; 
 a first intermediate portion between said anchoring flange and said first longitudinal upper flange and a second intermediate portion between said anchoring flange and said second longitudinal flange; 
 a first side panel extending down from said first longitudinal upper flange for mating, overlapping attachment to one of the opposite side surfaces of the vertical wall and a second side panel extending down from said second longitudinal upper flange for mating, overlapping attachment to the other of the opposite side surfaces of the vertical wall; and 
 at least one of said first and second side panels having an outwardly angled lower end portion structured and disposed to extend away from the vertical wall. 
   
   
   
       2 . The wall closure as recited in  claim 1  further comprising:
 each of the first and second side panels having said outwardly angled lower portion, and said outwardly angled lower portion of each of the first and second side panels being structured and disposed to extend away from the respective one of the opposite side surfaces.   
   
   
       3 . The wall closure as recited in  claim 1  wherein said first and second side panels are structured for overlapping attachment to the opposite side surfaces of the vertical wall to prevent entry of moisture between the wall closure and the vertical wall. 
   
   
       4 . The wall closure as recited in  claim 1  wherein said outwardly angled lower end portion provides increased rigidity and strength to said integral, one-piece body. 
   
   
       5 . The wall closure as recited in  claim 2  wherein said outwardly angled lower portion of said first and second side panels, is structured and disposed for providing increased rigidity and strength to said integral, one-piece body. 
   
   
       6 . The wall closure as recited in  claim 1  wherein said integral, one-piece body is formed of galvanized steel. 
   
   
       7 . The wall closure as recited in  claim 1  wherein said integral, one-piece body is formed of aluminum. 
   
   
       8 . The wall closure as recited in  claim 1  wherein said integral, one-piece body is formed of plastic. 
   
   
       9 . A wall closure for installation over the top end of a vertical wall on a roof structure, wherein the vertical wall includes a top surface and opposite side surfaces;
 said wall closure comprising:   an integral, one-piece body comprising:
 a central longitudinal anchoring flange for mating attachments to the top surface of the vertical wall; 
 first and second longitudinal upper flanges on opposite sides of said anchoring flange; 
 a first intermediate portion between said anchoring flange and said first longitudinal upper flange and a second intermediate portion between said anchoring flange and said second longitudinal flange; 
 a first side panel extending down from said first longitudinal upper flange for mating, overlapping attachment to one of the opposite side surfaces of the vertical wall and a second side panel extending down from said second longitudinal upper flange for mating, overlapping attachment to the other of the opposite side surfaces of the vertical wall; and 
 said first and second side panels each having an outwardly angled lower end portion structured and disposed to extend away from respective opposite side wall surface of the vertical wall and said outwardly angle lower portion of said first and second side panels providing increased rigidity and strength to said integral, one-piece body.
