<p>METHOD AND APPARATUS FOR FORMING CRYPTS A collapsible crypt form comprises an elongate rigid upper wall and two depending elongate rigid side walls joined at their adjacent margins by elongate rounded strips of resilient sheet material. Actuating means are connected to reinforcing rails at the lower edges of the side walls to extend them away from each other to operating position and retract them toward each other to reduce the effective height and width of the form for release from a finished recess. A back plate is held against the aft end of the body to prevent entry of flowable concrete and is disconnected from the body and removed from the recess after the body has been removed. A plurality of forms are placed in side by side spaced relation on a concrete slab with their forward ends in alignment with the forward edge of the slab and form plates are secured to the forms, locking them together and preventing loss of concrete. The concrete is poured and leveled to produce a tier of recesses with partition walls between them and a new slab above them. The process is repeated until the desired number of tiers are completed.</p> |
