However, since the upper end of the decorative cap is inserted into the fitting portion of the drywall material, there is a risk that the decorative cap will come off from the wall body depending on the fitting state of the drywall material.

In order to solve such a drawback, the present invention is a jointer for vertical joints that covers the joint portion of the dry wall material. The jointer for vertical joints is composed of a floor board and a decorative cap, and the floor board is a long plate material. The decorative cap consists of a vertical flat decorative surface portion and an engaging portion protruding in the longitudinal direction in the center of the back surface of the decorative surface portion, and the upper end of the decorative surface portion is on the indoor side. A step that is inclined and bent, a bottom piece that is bent upward at the tip of the step, a step piece that is bent indoors at the tip of the bottom piece, a fixed piece that protrudes upward at the tip of the step piece, and left and right of the fixed piece. Provided is a jointer for vertical joints formed by a back surface having both ends folded back indoors and an insert piece having the tip of the back surface protruding indoors.

According to the jointer for vertical joints according to the present invention, an insertion piece inserted into the fitting groove of the floor plate and a fixing piece fixed to the wall base are formed at the upper end of the decorative surface portion of the decorative cap. , (1) The upper part of the decorative cap can be securely fixed to the wall base. (2) Since the fixing piece is stable, the upper part of the decorative cap can be easily fixed. (3) The makeup cap does not come off. There are features and effects such as.
