ABSTRACT:
A latching bolt mechanism for fastening adjacent concrete form panels together to make a larger form work is disclosed. The mechanism includes a base permanently mounted on a form panel and a slidably attachable and detachable latching bolt mechanism having a tapered engagement pin for penetrating aligned apertures in the side rails of adjacent panel forms. The latching bolt further includes a tapered pin sleeve engaging portion that is received in the central bore of a pin sleeve, allowing transverse, shearing forces on the engagement pin to be readily dissipated. The pin sleeve in turn reciprocates within the central bore of a self-lubricating guide sleeve, which is seated within a housing block. A detachable mounting system includes a mounting bracket attached to the form panel and mating flanges on the housing block.
