Form for Casting Light Weight Composite Concrete Panels

Abstract

A concrete form for supporting a steel frame above a pouring pad comprises a vertical wall configured to be fastened to the steel frame, a marker on the vertical wall for spacing the frame a predetermined distance above the pouring pad, and a sealing member extending from a lower edge of the wall for sealing the form to the pouring pad. Preferably, the vertical wall has an upper portion, a horizontally offset lower portion, and a shoulder there between which engages an edge of the steel frame. The sealing member is preferably a lip extending from the vertical wall at an obtuse angle and engaging the pouring pad at an obtuse angle.

1 . A concrete form for supporting a steel frame above a pouring pad, said form comprising
 a vertical wall configured to be fastened to the frame;   a marker on said vertical wall for spacing the frame a predetermined distance above the pouring pad; and   a sealing member extending from a lower edge of said vertical wall for sealing the form to the pouring pad.   
   
   
       2 . A concrete form as in  claim 1 , said vertical wall comprising an upper portion and a lower portion, and said marker comprising a shoulder between said upper and lower wall portions. 
   
   
       3 . A concrete form as in  claim 2 , wherein said upper and lower wall portions are horizontally off-set from one another at said shoulder. 
   
   
       4 . A concrete form as in  claim 1 , wherein said sealing member comprises a lip extending from said vertical wall at an obtuse angle, and engaging the pouring pad at an obtuse angle. 
   
   
       5 . A concrete form as in  claim 1 , where in said sealing member comprises a leg extending horizontally from said vertical wall and a seal on said leg configured to engage the pouring pad. 
   
   
       6 . A concrete form as in  claim 5 , further comprising one or more ribs on an interior surface of said horizontal leg. 
   
   
       7 . A concrete form for supporting a frame member above a pouring pad, said form comprising,
 a vertical wall having an upper portion and a lower portion,   a shoulder between said upper and lower wall portions for supporting the frame member at a predetermined distance above the pouring pad, and   a sealing member on said lower wall configured to engage the pouring pad.   
   
   
       8 . A concrete form as in  claim 7 , wherein said sealing member comprises a lip extending from said lower wall at an obtuse angle. 
   
   
       9 . A concrete form as in  claim 7 , wherein said lower wall is horizontally off-set from said upper wall to form a reveal in an edge of a concrete panel cast with the form. 
   
   
       10 . A concrete form for supporting a frame member above a pouring pad, said form comprising,
 an upper vertical wall configured to be fastened to the frame member,   a lower vertical wall, said lower wall being horizontally offset from said upper wall,   a shoulder between said upper and lower walls configured to engage an edge of the frame member, and   a lip extending at an obtuse angle from said lower vertical wall and configured to engage the pouring pad at an obtuse angle,   said upper wall, lower wall, shoulder and lip being a unitary extrusion.
