and polypropylene homopolymer reprocessed 0047 fig6 shows the void former cast in place within a concrete structure 62 with the anchor a embedded within the structure as there shown the sections 10 12 of the void former f are in complimental engagement and capture the anchor a therebetween once the concrete structure has sufficiently cured the void former may be removed by swinging the sections 10 12 upwardly about the hinge provided by the bridge elements 42 44 such swinging may be achieved by inserting rods into the bores 22 and 28 and then moving these rods toward one another to spread the sections 10 12 into the condition shown in fig1 and 11 thus releasing the catch once the sections are spread to fully disengage the catch 18 from beneath the anchor a the void former may be easily removed from the concrete structure leaving a clean void around the anchor the bottom shell of the void former is injected molded with a mold having portions for the sections 10 and 12 disposed in a configuration corresponding generally to the open configuration shown in fig1 and 11 such configuration enables the catch 18 to be formed and removed from the mold as the part is removed the sections 10 and 12 are pivoted relative to one another about the hinge provided by the bridges 42 such hinging of the sections by bending of the bridges before the molded part is fully cured serves to alter the.
