Wall Opening Form

Abstract

Disclosed is a frame member for forming an opening through an insulating concrete form wall having opposed first and second forms. The frame member comprises an elongate member dimensioned to extend between the opposed forms. The elongate member is composed of a natural fiber plastic composite material having an opening forming surface and a wall forming surface and a pair of longitudinal retention fins extending from the wall forming surface. Each of the retention fins has a distal lip portion wherein the lip portions cooperate to form a hollow between the lip portions and the wall forming surface. Also disclosed is a frame for forming an opening through an insulating concrete form wall comprising at least three frame members and at least two corner connectors for connecting said frame members. The corner connectors comprise a bracket insertable into the hollows.

1 . A frame member for forming an opening through an insulating concrete form wall having opposed first and second forms, the frame member comprising an elongate member dimensioned to extend between the opposed forms, the elongate member composed having an opening forming surface and a wall forming surface and a pair of longitudinal retention fins extending from said wall forming surface, each of said retention fins having a distal lip portion wherein said lip portions cooperate to form a hollow between said lip portions and said wall forming surface. 
   
   
       2 . The frame member of  claim 1  wherein said elongate member further comprises first and second longitudinal edges having a flange extending parallel to said retention fins. 
   
   
       3 . The frame member of  claim 2  wherein said flanges and said retention fins are spaced apart a distance sufficient to receive at least one wall form therebetween. 
   
   
       4 . The frame member of  claim 3  wherein at least one of said flanges and said retention fins are spaced a sufficient distance apart to receive two wall forms therebetween. 
   
   
       5 . The frame member of  claim 1  further including a nailing strip extending from said opening forming surface. 
   
   
       6 . The frame member of  claim 1  wherein said opening forming surface is tapered from a center longitudinal portion to an edge portion so as to provide a sloped window sill. 
   
   
       7 . A frame for forming an opening through an insulating concrete form wall, the frame comprising:
 at least three frame members according to  claim 1 ; and   at least two corner connectors for connecting said frame members, the corner connectors comprising a bracket insertable into said hollows.   
   
   
       8 . The frame of  claim 7  wherein said frame is adapted to form a door opening comprising three frame members and two corner connectors. 
   
   
       9 . The frame of  claim 7  wherein said frame is adapted to form a window opening comprising four frame members and four corner connectors. 
   
   
       10 . The frame of  claim 7  wherein each of said corner connectors comprises first and second orthogonal panels having a thickness corresponding approximately to the distance between said lips and said wall forming surface of said frame members and a width corresponding approximately to the distance between said first and second retention fins. 
   
   
       11 . The frame of  claim 10  wherein said corner connectors further include stiffening ribs exterior to the orthogonal angle of said corner bracket. 
   
   
       12 . A frame for forming an opening through an insulating concrete form wall having opposed first and second forms, the frame comprising:
 at least three frame members, each of said frame members comprising an elongate member dimensioned to extend between the opposed forms, the elongate member being having an opening forming surface and a wall forming surface and a pair of longitudinal retention fins extending from said wall forming surface, each of said retention fins having a distal lip portion wherein said lip portions cooperate to form a hollow between said lip portions and said wall forming surface; and   at least two corner connectors for connecting said frame members, the corner connectors comprising a bracket insertable into said hollows.   
   
   
       13 . A frame kit for forming an opening through an insulating concrete form wall, the frame kit comprising at least three frame members according to  claim 1  and at least two corner connectors for connecting said frame members, the corner connectors comprising a bracket insertable into said hollows. 
   
   
       14 . The frame kit of  claim 13  comprising four frame members and four corner connectors. 
   
   
       15 . A frame kit for forming an opening through an insulating concrete form wall having opposed first and second forms, the frame kit comprising
 at least three frame members, each of said frame members comprising an elongate member dimensioned to extend between the opposed forms, said elongate member having an opening forming surface and a wall forming surface and a pair of longitudinal retention fins extending from said wall forming surface, each of said retention fins having a distal lip portion wherein said lip portions cooperate to form a hollow between said lip portions and said wall forming surface; and   at least two corner connectors for connecting said frame members, said corner connectors comprising a bracket insertable into said hollow.   
   
   
       16 . The frame of  claim 7  wherein the frame members are formed from a natural fiber composite material. 
   
   
       17 . The frame kit of  claim 13  wherein the frame members are formed from a natural fiber plastic composite material. 
   
   
       18 . The frame kit of  claim 15  wherein the frame members are formed from a natural fiber plastic composite material.
