JP6843642B2 - Joiner for outside corner - Google Patents

Description

The present invention relates to a joiner for outside corners formed by joining the longitudinal ends of drywall materials used in buildings and structures. More specifically, the present invention relates to a joiner for a protruding corner, which ensures a reliable and strong fitting when the decorative cap forming the protruding corner is fitted to the floor board.

Generally, a drywall material having a sandwich structure with a metal plate as a surface material, a synthetic resin foam as a core material, and a sheet-like material as a backing material, or a drywall material made of an inorganic material is used to form a horizontal wall. When the body is formed, the protruding corners are formed by abutting the drywall materials in the longitudinal direction, and the protruding corners are made by hitting the L-shaped protruding corner material / inside corner material with the brain, or the floorboard and decorative cap. There is a method of forming a protruding corner portion by fitting the two members. (See Patent Documents 1 and 2)

Japanese Unexamined Patent Publication No. 2000-001964 JP-A-2015-175207

Patent Documents 1 and 2 are a method of forming a protruding corner portion by fitting two members, a bedding board and a decorative cap. Cited Document 1 is constructed by deforming the first wall portion and the second wall portion, which have no margin in molding and are decorative surfaces, at the time of construction. Further, Cited Document 2 relates to a connecting member of an outer wall material that fits a joint cap to a joiner attached to a wall base, but this is also constructed by deforming the decorative surface during construction. For this reason, it was difficult to keep the angle of each decorative surface at 90 degrees.

In order to solve such a problem, the present invention has a protruding corner joiner that covers the protruding corner of the decorative surface portion of the dry wall material. The protruding corner joiner has a long bedding plate and a short decorative cap. The floor plate is formed from the horizontal part and the fitting part, the horizontal part forms a horizontal fixed piece at about 90 degrees, and the fitting part bends the substantially central part of the horizontal part upward. The two guide pieces formed by the above and the tips of both guide pieces are bent inward and the tips are bent inward to form a fitting groove having a substantially U-shaped cross section, and the fitting is projected into the fitting groove. It is composed of a long member formed from a joint claw, and the decorative cap is formed from a horizontal decorative surface portion and a decorative surface portion formed at approximately 90 degrees, and is formed from an engaging portion protruding in the longitudinal direction in the center of the back surface to engage. The portion is formed of a rising portion that is bent at a position that allows protrusion to the center of the back surface of the decorative surface portion at 45 degrees and an engaging piece that is formed so as to project outward near the tip of the rising portion. An inwardly curved step, a waterproof piece with the tip of the step protruding upward, a fixed piece with the central part of the waterproof piece protruding upward, a protruding piece with the central part of the fixed piece protruding indoors, and a protruding piece. Provided is a joiner for an outside corner having a groove formed by the above and a fixing hole formed in a substantially central portion of the groove.

As described above, according to the outside corner joiner according to the present invention, (1) since the upper part of the decorative cap is fixed to the wall base, the decorative cap is securely fixed and does not rattle. (2) Since the fixing hole is formed in the groove portion formed in the fixing piece, the fixing position does not vary and no gap is generated in the connecting portion. (3) With the protruding pieces and grooves formed on the fixing pieces that protrude toward the indoor side, the fixtures (nails) for fixing through the fixing holes are struck horizontally on the indoor side and on the wall base without shaking from side to side. Can be set up. There are features and effects such as.
