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.

Abstract: A form tie for joining the sidewalls of a polymeric concrete form comprises a pair of end trusses with an intermediate web truss. Each end truss comprises a pair of vertical struts with interior and exterior pairs of horizontal struts extending therebetween. The width of the web truss corresponds to the desired lateral distance between the interior surfaces of the form sidewalls. Upper and lower rectangular trusses and an intermediate truss are formed within each truss and rigidified by diagonal struts. The exterior struts of each end truss are embedded in the polymeric form of the sidewalls during the molding process with the interior struts of each end truss sealing the mold openings to prevent expansion of the foam from the mold. The interior struts are coplanar with the form sidewalls and serve as a visual gauge that the form and tie have been properly positioned. End ties having a height of one-half of the form sidewall are extended between the sidewalls at the ends of each form.

Abstract: A form tie for joining the sidewalls of a polymeric concrete form comprises a pair of end trusses with an intermediate web truss. Each end truss comprises an interior vertical strut and a longer exterior strut with interior and exterior pairs of horizontal struts extending therebetween. Upper and lower rectangular trusses and an intermediate truss are formed within each truss and rigidified by diagonal struts extending between the ends of the exterior vertical strut and interior vertical strut. The exterior struts of each end truss are coplanar with the exterior sidewall surface with the interior strut of each end truss being coplanar with the interior sidewall surface. The coplanar relationship of the struts serve as a visual gauge that the form with tie has been properly manufactured and assures that the end trusses extend throughout the width of each sidewall. End ties having a height of one-half of the form sidewall are extended between the sidewalls at the ends of each form.

Abstract: 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.

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.

Abstract: A wall clip for use with a concrete form comprises a vertical nailing surface or stud for receiving fasteners of finishing material therethrough. Linkage structures extend upper and lower anchors from the upper and lower ends of the stud and into the cavity between the form sidewalls. The anchors maintain the stud along the sidewalls during concrete pouring, curing and subsequent material fastening. The anchors further reinforce the concrete laden form.
