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).
