A device for interlocking form panels. It contemplates an elongated member having first and second sections that are substantially planar and have first and second ends and first and second sides. First and second flange members are attached to the ends and diverge from the elongated member. These flange members are also substantially planar, parallel to each other and protrude perpendicularly out of the plane of the elongated member an equal distance from the first and second sides of the elongated member. A first pair of guide rib members is attached to the elongated member at a point near the first end of the elongated member, is in a parallel planar relationship with the first diverging flange member, and protrudes perpendicularly from the first side of the elongated member. This first pair of guide rib members is attached at a point from the first diverging flange member so as to define a distance that is substantially equal to the thickness of a form panel. A second pair of guide rib members is attached to the elongated member at a point near the second end of the elongated member, is in a parallel planar relationship with the second diverging flange member, and protrudes perpendicularly from the second side of the elongated member. This second pair of guide rib members is attached at a point from the second diverging flange member so as to define a distance that is substantially equal to the thickness of a form panel. Frangible bridges for separating the first section of the tie from the second section of the tie are perpendicularly situated along the longitudinal axis of the tie from the first end to the second end.
A tie for interlocking form panels comprising:
A form tie for a concrete wall forming system, the concrete forming system including at least one pair of panels intended to be maintained in an upright position and held in a mutually spaced apart relationship by one or more of said form ties, the panels each having inner and outer faces and upper, lower and side edges in said upright position, whereby concrete can be poured between the panels to form the concrete wall, the form tie comprising an elongated member having:
