  In recent years, in steel frame houses, reinforced concrete houses, apartments, etc., there are cases where the wall and the wall base of the partition are constructed by the light iron wall foundation method (LGS method). This method combines a runner, a stud, and a sway stop, which are components of a wall foundation material, with spacers as necessary to make a frame having a plurality of sections, and this frame is made of wall material such as gypsum board It is a construction method to stick and make a wall base. Finishing materials such as wallpaper and cloth are pasted on the surface of wall material such as gypsum board, and on the surface of this finishing material, in order to protect gypsum board and finishing material from collisions such as stretcher and wheelchair, various Protective material attached. Among these protective materials, the protruding corner protecting member for protecting the protruding corner portion of the wall surface, so-called corner guard, is fixed to the stud which is the aggregate of the wall base with a tapping screw or the like. When two plaster boards are pasted on a wall foundation constructed by a light iron wall foundation method (LGS construction method) and a fireproof structure wall is constructed, two plaster boards are overlapped at the corner of the wall surface. Therefore, the distance from the ridge line of the protruding corner to the stud must be increased. For this reason, in order to fix the projected corner protection member to the stud with a tapping screw, the projected corner protection member must be extended to both sides of the ridge line of the projected corner. Therefore, it is difficult to miniaturize the protruding corner protection member. Instead of fixing the corner protection member to the stud with a tapping screw, instead of using the adhesive or double-sided adhesive tape, it is not necessary to extend the corner protection member on both sides of the ridge of the corner. The corner protection member can be miniaturized. However, sufficient adhesion may not be obtained by merely bonding the corner protection member to a finish such as wallpaper or cloth.
