ABSTRACT:
A concrete form tie assembly in which the tie rod is formed from a high tensile strength flexible wire member, with the sleeve being formed of a flexible or yieldable material. A short sleeve member is inserted into the spacer sleeve adjacent one end with washer members on opposite ends thereof for retaining on the tie rod member which is provided with spaced protrusions for coaction with the wash members, the tube and washer assembly serving to rigidify the assembly for assisting in insertion and removal of the tie rod and sleeve as a unit. The leading end of the tube and washer assembly may be provided with a conical end to act as a guide. The ends of the tie rod member are enlarged, such as by welding head members thereto, the head members being configured for coaction with conventional hairpin or snap tie wedge members.
