Burial vault

Abstract

A burial vault having preformed hollow fiberglass resin base and cover shells, the shells having fiberglass anchor loops integrally formed on their inner surfaces. The shells are filled with a cement-sand-stone composition that is mechanically locked to the anchor loops on the inside surface of the liners, the cement-sand-stone composition including a plurality of straight steel wires of short length randomly disposed throughout the walls to increase the tensile strength and crack-resistance of the vault.

I claim: 
     
       1. A burial vault comprising: a hollow one-piece fiberglass resin shell having the shape of a base for a burial vault,   a hollow one-piece fiberglass resin shell having the shape of a cover for said base,   a cement-sand-stone composition completely filling each of said shells,   and a number of fiberglass anchor loops within each of said shells and integral therewith for providing physical attachment between the set cement-sand-stone composition and the inner surface of said shells.   
     
     
       2. A vault according to claim 1 including a plurality of short steel wires in said cement-sand-stone composition. 
     
     
       3. A vault according to claim 1 wherein said base shell includes an opening at the top and a flange around the periphery of the opening in the base and said cover includes a groove around the periphery of the cover for matingly engaging the flange on said base. 
     
     
       4. A burial vault comprising a hollow walled rectangular shell preformed from a fiberglass resin composition, said shell including side walls and end walls closed at the top and a double-walled base having an inside wall connected to the bottom edge of the inner walls of said side walls and end walls to form a chamber for a coffin, and a base wall connected to the outer walls of said side walls and end walls in a spaced relation to said inner base wall, a hollow rectangular shaped cover shell preformed from a fiberglass resin composition, a cement-sand-stone and steel wire composition completely filling the shells and a plurality of fiberglass loops formed on the inner surface of the side walls, end walls and base walls for securing the cement-sand-stone and steel wire composition to the inner surfaces of the walls. .Iadd.5. A burial vault comprising a hollow rectangular shell preformed from a fiberglass resin composition, said shell including side walls, end walls and a base wall at the bottom closing the bottom of the side walls and end walls to form a chamber for a coffin, a cement-sand-stone composition covering the outside surface of the side walls, end walls and base wall and a plurality of anchoring means partially embedded in the surface of the shell for mechanically locking the cement-sand-stone composition to the surfaces of the walls. .Iaddend..Iadd.6. A vault according to claim 5 wherein said anchoring means comprises fiberglass loops. .Iaddend.
