A form tie made of an expanded metal material extends between the sidewalls of a concrete form. A web traverses the sidewalls and includes, at the opposed ends of the web, first and second parallel flange walls with a supplemental web wall extending therebetween. A return wall extends from the end of the second flange wall. The use of the flange walls, supplemental webs and return walls stiffens the resulting tie so as to preclude sidewall displacement upon a static load thereon. The same elements resist longitudinal and lateral shifting of the tie and attached sidewalls during concrete pouring. The maintenance of the sidewalls by the tie during static and dynamic load conditions allow for easy form connection as well as prevents buckling and/or "blow out" of the forms during concrete pouring.
In a concrete form comprising first and second laterally spaced-apart sidewalls for presenting a cavity therebetween, at least one improved form tie comprising:
In a concrete form comprising first and second laterally spaced-apart sidewalls with a pair of end walls and intermediate partition walls extending from each sidewall for presenting a cavity therebetween, at least one improved form tie comprising:
