Abstract
A gang form for use with a concrete form system is provided. The concrete form system has a plurality of said gang forms and a plurality of tie rods. An improved insert having four sides is positioned between two adjacent form panels having flanges with flange openings therein. Side openings in the third and fourth sides of the insert are aligned with the flange openings. Attachment devices are inserted in the side openings and flange openings to attach the insert to the two adjacent form panels and to provide the gang form. At least one lock member is rotatably attached to the second side of the improved insert. One of the plurality of tie rods extends through a tie rod opening in the first and second sides of the insert and is firmly secured to the insert by moving the lock member from an unlocked position to a locked position. Thus, the gang form is interconnected to the concrete form system.
