ABSTRACT:
A formwork is to be used with a wall form assembly for forming a door opening in a concrete wall. The formwork mainly includes a parallel pair of mold frame members that are to be disposed between a parallel pair of wall form plates which confine a concrete pouring space for forming a concrete wall, and that are adapted to be mounted to the wall form plates. The mold frame members have partition plates that extend toward and that overlap one another. The partition plates are movable with the mold frame members towards and away from each other and confine a door opening that is isolated from the concrete pouring space. The formwork is easy to assemble and disassemble, is suitable for large-scale construction, and is adjustable to fit the size of the door frame that is to be installed.
