Abstract

A synthetic plastic wall tie of variable lengths for use with concrete forms. The tie has a pair of T-shaped end sections at its opposite ends. Each of the T-shaped end sections including a stem having a sufficient thickness for receiving an end of a screw in threaded engagement therewith. The T-shaped end sections have parallel cross pieces at opposite ends of the tie. An intermediate wall tie section connects the T-shaped end sections together. The intermediate wall tie section has a pair of round flange-like water-stops extending radially outwardly out of the intermediate wall tie section and are joined therewith in integral one-piece assembly therewith. The water-stops serve to inhibit water flow axially of the wall tie and through a concrete wall structure where the tie is embedded. The round flange-like water-stops further serve to provide means for locating reinforcing rods extending at right angles to the wall ties when the wall ties are mounted in a concrete form.

Claims

1. In a modular formed plastic concrete form structure, wherein the improvement comprises a pair of modular concrete forming panels each comprised of a series of modular concrete forming sections stacked on top of one another and also disposed in end-to-end relation, the sections each having means on its upper and lower edges and its opposite vertical edges for interlocking the sections in stacked, end-to-end engagement with one another, the panels being positioned in spaced opposed relation, spaced T-shaped tie slots in the opposed sections and which slots are hidden from view when viewing outer surfaces of the stacked forming sections, tie located indicia on outer surfaces of the forming sections for providing blind sighting means to enable screws to be screwed through a wall covering, the indicia, the forming section and into the synthetic plastic ties to securely anchor an exterior wall finishing covering to the forming sections, synthetic plastic wall ties for use with concrete forms, the wall having a pair of T-shaped end sections including a tie stem having a sufficient thickness for receiving an end of a screw in threaded engagement therewith, the T-shaped end sections having parallel cross pieces at opposite ends of the tie secured to said modular concrete forming sections, the tie cross pieces having outer tie faces positioned generally at right angles to a plane through the length of the wall tie enabling said screw to be screwed through into the associated tie stem for attaching a wall covering thereto, the tie having an intermediate wall tie section, the intermediate wall tie section having a pair of transversely spaced round flange-like water-stops spaced in gap relation between the concrete forming sections extending radially outwardly out of the intermediate wall tie section and being joined therewith in integral one-piece assembly therewith, the water-stops serving to inhibit water flow axially of the wall tie and through a concrete wall structure where the tie is embedded, the round flange-like water-stops further serving to provide means for locating reinforcing rods extending at right angles to the wall ties when the wall ties are mounted in gap relation to the concrete forming sections in a concrete form.

2. The wall tie of claim 1 further characterized by the water-stop being located approximately 21/2 or more inward from an inside end of the nearest associated T-shaped end section.

3. The form structure of claim 1 further characterized by the tie locator indicia comprising longitudinally extending rows of I-shaped embossments extending along upper and lower edges of each section.

4. The form structure of claim 1 further characterized by the tie locator indicia comprising longitudinally extending rows of I-shaped embossments extending along upper and lower edges of each section, each embossment being transversely aligned with one of the slots.

5. In a modular synthetic plastic concrete form structure, wherein the improvement comprises a pair of modular concrete impervious forming panels comprised of a series of opposed modular concrete forming sections stacked on top of one another and also disposed in end-to-end relation, the sections each having means on its upper and lower edges and its opposite vertical edges for interlocking the sections in engagement with one another, the panels being positioned in spaced opposed relation, tie slots in the opposed sections positioned in longitudinally spaced rows along the upper and lower edges, synthetic plastic ties arranged in vertically spaced rows along upper and lower edges of the sections, the ties being positioned in vertically spaced horizontally extending rows and the ties having opposite enlarged tie ends retainingly engaged in said tie slots securing the sections in opposed spaced relation, modular transversely extending closure panels mounted between the opposed panels providing end closures for confining poured concrete within the form defined by the opposed panels and the end closure panels, modular attachment means provided between opposed faces of the opposed panels and opposite ends of the closure panels to secure the assemblage in unitary relation to define a concrete form, the ties and the forming sections having heights at substantial variance with respect to one another when said ties are assembled in the rows at upper and lower edges of the forming sections leaving a substantial open area between the upper and lower rows of ties enabling concrete to be rapidly poured between the forming sections with low flow impedance from the ties, the reinforcing ties each being secured in permanent embedded assembly at opposite ends with the synthetic plastic opposed panels and also with the concrete when poured and hardened in the thus provided form to provide an insulated concrete wall with the synthetic plastic panels permanently attached to the exterior of the concrete wall, the ties each having a pair of T-shaped end sections at opposite ends of the wall tie, each of the T-shaped end sections including a stem having a sufficient thickness for receiving an end of a screw in threaded engagement therewith, the T-shaped end sections having parallel cross pieces at opposite ends of the tie, an intermediate wall tie section connecting the T-shaped end sections together, the intermediate wall tie section having a pair of round flange-like water-stops extending radially outwardly out of the intermediate wall tie section and being joined therewith in integral one-piece assembly therewith, the water-stops being spaced inwardly of the forming section, the water-stops serving to inhibit water flow axially of the wall tie and through a concrete wall structure where the tie is embedded, the round flange-like water-stops further serving to provide means for locating reinforcing rods extending at right angles to the wall ties when the wall ties are mounted in a concrete form, the cross pieces having outer faces positioned generally at right angles to a plane through the length of the wall tie enabling a screw to be screwed there through into the associated stem for attaching a wall cover thereto.

6. The concrete form structure of claim 5 further characterized by the water-stop having a diameter of at least 1".

7. The concrete form structure of claim 5 further characterized by the water-stop having a thickness of 0.100".

8. The concrete form structure of claim 5 further characterized by the water-stop having a diameter of at least 1" and being 0.100" thick.

9. The concrete form structure of claim 5 further characterized by the water-stop being located approximately 21/2 or more inward from an inside end of the nearest associated T-shaped end section.
