STAY-IN-PLACE FORM SYSTEMS FOR WINDOWS AND OTHER BUILDING OPENINGS

摘要

A stay-in-place buck for defining an opening in a cast concrete structure has a plurality of frame members arrangeable in an abutting relationship. Each of the frame members has a panel extending transversely between outer opposed panels of a stay-in-place form- work. Flanges extend from opposed edges of the frame member panel for abutment against outer surfaces of the outer opposed panels. Each flange has opposed mitered end edges for abutment against adjacent mitered end edges of flanges of adjacent frame members. The buck also includes fastener-receivers connectable to the panels of the frame members to form one or more fastener-receiving frames extending at least partially about a perimeter of the buck. Each fastener-receiver has mitered edge portions for abutment against adjacent mitered edge portions of adjacent fastener- receivers.
