Abstract
A support apparatus with a tie lock tool and a clamp for a concrete form system. Opposing form panels are held in fixed relation to one another with at least one form tie having either a loop head or button head extending between the form panels. A tie lock tool engages a waler positioned on the form panel. The tie lock tool has a form tie opening, configured to receive the head. A lock member, of the tie lock tool, has two claws and is rotatable between an unlocked and a locked position. The first claw has an extension beyond the second claw for abutting the head extended through the form tie opening when the lock member is unlocked. When the lock member is locked, the head is firmly held, thus securing the form tie to the tie lock tool, the waler and the form panel. A strong back of variable depth is secured to the tie lock tool with an adjustable clamp. Two arms of the clamp are connected to the tie lock tool, and an adjustable clamp member engages and tightens against the variable depth strong back to secure the strong back to the tie lock tool and support the concrete form system.
