Patent

CA 2391532

A void former for positioning an anchor within a concrete structure is comprised of a hollow polymeric body having first and second sections hinged together for movement between a closed condition engageable around the anchor received therebetween and an open condition in which the sections are separated at the lower portions thereof to release the anchor received therebetween. The void former is monolithically formed by injection molding and includes integrally formed latch elements on the respective sections for mutual engagement to secure the sections in the closed condition and a bridge between the sections to provide a hinged connection therebetween. In the injection molding process the sections are formed so as to be positioned in the open condition. Upon removal from the injection mold, the sections are hinged relative to one another by bending the bridge therebetween, before the polymer is fully cured. Such bending aligns the molecules of the polymeric material within the bridge to enable the bridge to serve as a hinge and sustain repeated bending.
