Abstract:
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° 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.
