  • Patent number: 5566518
    Abstract: A concrete form tie comprises a pair of laterally displaced sidewall support assemblies with a reinforcing web extending therebetween. The support assemblies bite into the exterior sidewall surfaces as positioned thereat by the web transversely extending between the support assemblies. The web comprises a pair of brackets as formed by a support strut extending through a notch at the top of the form sidewall with a hanger element depending therefrom. A bridge extends between the depending hangers and across a vertical cavity formed between the sidewalls. The tie resists pressures acting on the sidewalls to preclude blow out along the horizontal joints of form courses as well as lateral displacement of the sidewalls. A starter tie is disclosed for respectively securing the lower end of the first course of sidewalls to a footing. A finish tie is disclosed for maintaining the displacement of the sidewalls of the top course of forms.
