ABSTRACT:
A formwork, a device for clamping the formwork and a mechanism for actuating the clamping are taught. The formwork includes two molds, which mount together. The clamping device secures the mounted molds and allows the formwork to operate. The clamping device includes a movable member and a tension member, which locks the movable member to protruding sections of each mold. This clamping device is duplicated along the length of the protruding sections. The mechanism for actuating the clamping exerts force upon the movable member to secure it between the tension member and the protruding sections. This same mechanism can withdraw the movable member from the clamp. By this, the clamping is accomplished and a more efficient formwork is achieved.
