Patent

CA 2210406

A butt joint hanger (30) is disclosed having a central elongated rail (32) and two support elongated rails (34, 36) positioned on either side of the central rail (32). One or more U-channels (38) interconnect the three rails (32, 34, 36) at pivoting attachment points (40). The butt joint hanger (30) is inserted between two construction beams (94, 96) and the butt ends (108, 114) of two sheets of wallboard (104, 112) are attached to the central rail (32) by means of drywall screws (110). The two support rails (34, 36) abut against the surfaces of the wallboard flush with the nailing surfaces (98, 100) of the construction beams (94, 96) and the drywall screws (110) force the butt ends (108, 114) of the wallboard out of the plane (102) of the wallboard and into engagement with the central rail (32). This results in a depression area (116) adjacent both butt ends (108, 114) which can be easily filled with plaster (122) to produce a flat smooth butt joint (126).

Un support de joints en bout (30) est divulgué. Celui-ci comprend une barre centrale allongée (32) et deux barres de support allongées (34, 36) placées de chaque côté de la barre centrale (32). Un ou plusieurs profilés en U (38) relient les trois barres entre elles (32, 34, 36) à des points d'attache pivotants (40). Le support de joints en bout (30) est inséré entre deux poutres de construction (94, 96), et les extrémités des bouts (108, 114) de deux panneaux de revêtement (104, 112) sont fixées à la barre centrale (32) au moyen de vis de fixation de planches murales (110). Les deux barres de support (34, 36) butent contre les surfaces des panneaux de revêtement tout contre les fonds de clouage (98, 100) des poutres (94, 96), et les vis de fixation (110) appliquent une force contre les extrémités des bouts (108, 114) des panneaux de revêtement, les désalignant ainsi du plan horizontal (102) pour se rattacher à la barre centrale (32). Il en résulte une section renfoncée (116) adjacente aux deux extrémités des bouts des panneaux de revêtement (108, 114) qui peut facilement être remplie de plâtre (122) produisant ainsi un joint en bout lisse et plat. (126).
