Abstract
The concepts disclosed herein provide for a concrete mold that improves upon existing concrete molds known in the art. The hinged side-panel members that are locked to a hold-down frame allow for the mold to cure a concrete member, and then allow the concrete member to be removed without the need to break-down the frame surrounding the concrete member. During the pouring and ensuing curing process of the concrete member, the hinged side-panel members are secured to the hold-down frame and to each other in order to hold the concrete in the mold. Once the concrete is cured, the hinged side-panel members may be unlocked and opened quickly, allowing for expedient removal of the concrete member. After closing and re-locking the hinged side-panel members, the mold may be reused to cure another concrete member without the need to rebuild the frame around the mold.
