Plumbing and conduit protector plate

Abstract

A metal plate ( 11 ) for protecting plumbing pipes and plastic electrical conduits ( 13 ) from being pierced by a nail or screw when the wall covering is attached. Said plate is a generally flat rectangular metal plate ( 11 ) having metal tabs ( 12 ) for aligning said plate on concrete foundation form boards ( 10 ) and metal prongs ( 13 ) which act as nails to hold said plate in position until concrete ( 15 ) is poured. The concrete ( 15 ) flows around the concrete gripping prongs ( 14 ) where said concrete ( 15 ) bonds thereby locking said plate ( 11 ) permanently in place.

I claim:  
     
         1 . A metal plate which bonds to concrete foundations for protecting objects such as pipes from being pierced comprising: 
 (a) a sheet of flat metal,    (b) a metal positioning tab or tabs protruding from one side of said metal plate, and    (c) at least two sharp metal prongs protruding from the same side of said metal plate as (b) above, and    (d) at least two metal prongs protruding from the other side of said metal plate.    
     
     
         2 . A metal plate as in  claim 1  which is positioned over foundation form-boards by positioning tabs.  
     
     
         3 . A metal plate as in  claim 1  wherein said plate is temporarily attached to foundation form-boards by two metal prongs protruding from the face of said plate.  
     
     
         4 . A metal plate as in  claim 1  wherein said plate is mechanically bonded to the concrete foundation by two or more metal prongs protruding from the opposite face of said prongs in  claim 3.
