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.

La présente invention concerne un chambranle fixe pour définir une ouverture dans une structure en béton coulé et qui comporte une pluralité d'éléments de cadre qui peuvent être agencés dans une relation contiguë. Chaque élément de cadre comporte un panneau qui s'étend transversalement entre des panneaux opposés extérieurs d'un coffrage fixe. Des brides s'étendent à partir de bords opposés du panneau d'élément de cadre pour prendre appui contre des surfaces extérieures des panneaux opposés extérieurs. Chaque bride comporte des bords d'extrémité opposés à onglet pour prendre appui contre des bords d'extrémité adjacents à onglet de brides d'éléments de cadre adjacents. Le chambranle comprend également des récepteurs d'éléments de fixation pouvant être liés aux panneaux des éléments de cadre pour former un ou plusieurs cadres de réception d'élément de fixation qui s'étendent au moins partiellement autour d'un périmètre du chambranle. Chaque récepteur d'élément de fixation comporte des parties de bord à onglet pour prendre appui contre des parties adjacentes de bord à onglet de récepteurs d'élément de fixation adjacents.
