Abstract

An apparatus for forming a precast concrete structural member having openings formed therethrough, comprising: a cladding portion defining the shape of the structural member; stud members extending in the area defined by said cladding portion at preselected positions in which openings are to be formed; and inserts defining openings having upright wall portions that are of a length substantially equal to the depth of the openings to be formed, said inserts having a first open end and a second closed end by a frangible lid, being located said inserts such that said first ends are in contact with said cladding part and said stud members are secured to the interior surfaces of said frangible caps so that said structural member and said wall parts are permitted to be separated from inserts while said frangible lids and said stud members are secured to said liner portion.
