A form tie for joining a pair of form sidewalls includes first and second vertical struts presenting planar nailing surfaces for embedding in the first and second sidewalls. A web obliquely extends between the struts and across the cavity between the laterally spaced-apart sidewalls. The web includes a top strut which slopes between the vertical struts and across the cavity. The form ties are alternately placed in alternate 180.degree. orientations along the sidewalls such that the web extends in alternate directions across the cavity which enhances the form rigidity. Concurrently, the top web strut slopes in opposed direction to form a V-type seat for placement of a horizontal rebar within the cavity.

1. In a concrete form comprising first and second laterally spaced-apart sidewalls for presenting a cavity therebetween, the sidewalls joined by a plurality of improved form ties, each improved form tie comprising:a first strut embedded in one of the sidewalls; a second strut laterally displaced from the first strut and embedded in the other of said sidewalls in a parallel relationship with said fist strut; an uppermost third strut extending between said first and second struts and for bridging the cavity between the first and second sidewalls, said third strut inclined between said first strut and said second strut; at least one reinforcement strut below said third strut extending between said first and second struts, a plurality of said improved ties joining said sidewalls in a longitudinally spaced-apart relationship, said first and second struts of each form tie alternately positioned in said first or second sidewalls, whereby said uppermost third struts of successively adjacent ties alternately slope in up or down directions between said first and second sidewalls to present a seat adapted for placement of a longitudinally extending rebar atop the cavity between the first and second sidewalls.
