Description

  The present invention relates to a parting edge provided at a portion in contact with a wall surface of a ceiling.

  Conventionally, a ceiling is formed by supporting a ceiling base with a number of suspension bolts hanging from the ceiling slab and attaching a ceiling panel to the ceiling base.

  In the ceiling structure as described above, a parting edge is attached to a portion in contact with the wall surface of the ceiling to conceal a gap formed between the ceiling and the wall surface.

  By the way, since the parting edge that has been conventionally known is fixed to the wall surface, it is necessary to attach the parting edge according to the height of the ceiling supported by the ceiling base, which is very troublesome to install. There was an inconvenience that it took.

  In addition, since the parting edge is configured to support the outer peripheral portion of the lower surface of the ceiling, there is a disadvantage that when the outer peripheral portion of the lower surface of the ceiling is pushed up, it moves upward and the stability of the outer peripheral portion of the ceiling is poor.

  In order to eliminate such inconvenience, in the parting edge described in Patent Document 1, the fixing bar is abutted against the lower surface of the field edge forming the ceiling base, and the outer surface of the fixing bar is set along the wall surface. The fixing bar is fixed by tightening the tapping screw that is screwed into the edge, and the support bar is attached to the lower surface side of the fixing bar via a connector, and the lower surface of the ceiling is formed by the support piece formed on the inner side of the support bar. The outer peripheral portion is supported, and the outer peripheral portion of the ceiling is stabilized by pressing the upper peripheral portion of the ceiling with a pressing piece provided on the inner surface of the lower surface of the fixed bar.

  In addition, the ceiling is gently inclined in one direction, and water leaking from the ceiling slab to the top surface of the ceiling is caused to flow along the ceiling inclination, and the water leakage is applied to the flange portion formed on the upper surface side of the support bar. Water is collected so that water leaks from the upper surface of the ceiling and prevents the water leakage from dropping from the connecting portion of the ceiling panel forming the ceiling.
