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.
