Abstract
A form tie lock tool is provided which includes the combination of a cam lock member for use with hand set concrete panels and an anchor lock member for use with gang form concrete panels. The tool includes a frame having a first opening and a second opening formed therein. A tie lock member, including the cam lock member and the anchor lock member, is connected to the frame. A form tie having a pair of looped ends is insertable between a pair of the hand set form panels. In one embodiment, each of the looped ends is receivable through a slot in one of the hand set panels to be grippingly engaged by the cam lock member which is then rotatable in a first direction to secure the form tie between the hand set panels. Similarly, a form tie having a pair of looped ends is insertable between a pair of gang form panels. Each of the looped ends is receivable through a slot in one of the gang form panels to be grippingly engaged by the anchor lock member which is then rotatable in a second direction to secure the form tie between the gang form panels. In another embodiment, the cam lock member and anchor lock member are slidably movable toward the frame to grippingly engage the looped end of the form tie.
