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.

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.
