Abstract
A helical wedge tie, anywhere from 21/2 inches to 4 inches in length, (which is approximately the width of a standard brick), can be utilized to wedgingly engage the mortar in a wall after a helical main tie has been passed all the way through the mortar and secured in the concrete. The wedge tie may have the same helical pitch as that of the main tie, or it may be a pitch somewhat tighter or shorter to not only fill the space between the host tie and the mortar, but wedgingly engage the same. The auxiliary wedge pin may be pointed at both ends, pointed at one end, or even blunt at both ends. Successful fixes have been made where one end is sheared, and has a relatively chisel-like end. The method of the invention is directed to the reinforcing of a tie in a wall reinforcing environment, where the outer portion of the tie passes through a softer material, and a subsequent reinforcement of the tie portion in the soft material becomes desirable.
