Prefabricated sectional burial vault - has grooved circumferential edge providing interlocking joint without accessories

摘要

The vault has longitudinal pieces and end pieces of each chamber made by plane panels. The vault has a grooved surround frame (3) holding, by interlocking, the longitudinal panels (1) and end panels (2). Each surround also acts as a support for the separation slab between chambers, such an assembly giving a reinforced rigidity to the vault. Each surround has a top groove (3A) to take panels (1,2) of a top chamber, and a bottom groove (3B) to take the panels (12) of a bottom chamber.
