  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a protruding corner portion 1 of an inner wall using a corner member 10 as a reference form in order to explain the protruding corner portion of the inner wall using the corner member of the present invention. As shown in the figure, the projecting corner portion 1 has base boards 21 and 21 made of gypsum board or the like fixed to two adjacent surfaces of the pillars 22, respectively. A wall finishing material 23 such as a cloth is adhered to the surfaces of the base boards 21 and 21 and the corner member 10 in a state in which the corner member 10 is fixed to the surface of the end portion.

  As shown in FIGS. 2A to 2C, the corner member 10 includes a pair of projecting pieces 11 having a thickness of about 1.0 mm, which are connected to each other so as to form an angle of about 90 degrees. 11 and the reinforcement formed by projecting diagonally so as to face each other from the base end side of each of the projecting pieces 11, 11 in order to reinforce the corners formed by the projecting pieces 11, 11 Ribs 12 and 12 are provided, and in order to give a soft impression to the protruding corner portion 1 of the inner wall, the corner portion is rounded by chamfering the corner portion in an arc shape. In addition, the front end side of the overhang | projection pieces 11 and 11 is formed in the thin shape whose thickness is about 0.1-0.6 mm.

  The overhanging pieces 11, 11 have an overhanging length of 20 mm or more, and a putty or a wall finishing material (cross) 23 is bonded to the outer surface of the projecting portion of the rib 12 on the tip side. In order to increase the strength, a large number of concave strips 11a extending in the longitudinal direction are formed, and a double-sided pressure-sensitive adhesive tape (not shown) is attached in advance to the inner surface.

  As shown in FIG. 1, the ribs 12, 12 are extended from the other overhanging piece 11 to the thickness of the base board 21 to which the overhanging piece 11 is fixed. And the extension direction of the other overhanging piece 11 is provided in the area from one overhanging piece 11 to the thickness of the base board 21 to which the overhanging piece 11 is fixed. Yes.

  Hereinafter, the construction method of the protruding corner portion 1 of the inner wall will be described. First, as shown in FIG. 3A, after the basement boards 21 and 21 are respectively fixed to the two adjacent surfaces of the pillar 22 to form the wall base, a pair of baseboards are formed as shown in FIG. The corner member 10 is attached by sticking the inner surface side of the overhanging pieces 11, 11 to the end surface of the base board 21 with a double-sided tape (not shown). When the base boards 21 and 21 are fixed to the pillars 22, the base boards 21 and 21 are fixed in a state of being separated from each other so as not to contact the ribs 12 and 12 of the corner member 10. .

  Subsequently, as shown in FIG. 4A, a slight step portion formed between the pair of projecting pieces 11 and 11 of the corner member 10 and the surface of the base board 21 and 21 is filled with the putty P. After applying the base, the wall finishing material 23 such as a cloth is pasted on the surfaces of the base boards 21 and 21 and the corner member 10 as shown in FIG. .

  As described above, the corner member 10 is provided with the reinforcing ribs 12 and 12 on the inner surface side of the corner portion formed by the pair of projecting pieces 11 and 11, so that the base board fixed to the column 22 21 and 21 do not need to form corners of the wall base, and when the base boards 21 and 21 are fixed to the pillars 22, the ends of both base boards 21 and 21 contact the ribs 12 and 12 of the corner member 10. Since it should just be separated appropriately so that it may not touch, the workability is good and the inner corner 1 of the inner wall can be finished cleanly efficiently in a short time.

  Moreover, in this corner member 10, about the overhang | projection direction of one overhanging piece 11, in the area | region from the other overhanging piece 11 to the thickness of the base board 21 which sticks the overhanging piece 11, And about the extension direction of the other overhanging piece 11, the ribs 12 and 12 for reinforcement are provided in the area | region from the one overhanging piece 11 to the thickness of the base board 21 which sticks the overhanging piece 11. FIG. Therefore, when the corner member 10 is attached, the ribs 12 and 12 are not obstructed, and the corner member 10 can be reliably attached at an appropriate position.

  Moreover, in this corner member 10, since the corner is rounded by chamfering the corner in an arc shape, in order to give a soft impression to the protruding corner 1 of the inner wall, the protruding corner 1 Even when it is rounded, it can be easily constructed without increasing the number of steps.

  In addition, in the corner member 10 of the reference form described above, the reinforcing ribs 12 and 12 project obliquely from the base end side of each projecting piece 11 and 11, but for example, FIG. Loop-shaped ribs 12a and 12b may be employed as in corner members 10A and 10B according to an embodiment of the present invention shown in FIG. 6B, and ribs 12a as in corner member 10C shown in FIG. In addition, a rib 12c that connects the corner and the rib 12a may be provided.

  Further, ribs 12d and 12e protruding at 45 degrees from the respective corners may be employed as in the corner members 10D and 10E shown in FIGS. 6A and 6B. FIG. A corner portion and a rib together with the rib 12f like the corner member 10F shown in FIG. 5 and a rib-shaped rib 12f connecting the pair of overhanging pieces 11, 11 and the corner member 10G shown in FIG. You may provide the rib 12g which connects 12f.

  Further, when the reinforcing ribs 12h, 12i, and 12j are formed by thickening the corner portions as in the corner members 10H, 10I, and 10J shown in FIGS. The strength of the corners formed by the corner members 10H, 10I, and 10J is further improved, making it difficult to be damaged or deformed.

  Further, as in the corner member 10K shown in FIG. 8A, a rib 12k having a shape in which the tip corner portion of the saddle-shaped rib 12f of the corner member 10F described above is chamfered may be employed. Like corner member 10Ka shown in figure (b), corner members 10A to 10J can also be putty or wall finish (cross) by forming a number of recesses 11a extending in the longitudinal direction on the entire outer surface. 23 can further increase the adhesive strength.

  However, as for the ribs 12a to 12k, as in the case of the rib 12 described above, with respect to the extending direction of the one overhanging piece 11, the base board for fixing the overhanging piece 11 from the other overhanging piece 11 Within the area up to the thickness of 21 and the extension direction of the other overhanging piece 11, the area from one overhanging piece 11 to the thickness of the base board 21 to which the overhanging piece 11 is fixed. Needless to say, it must be kept inside.

  Moreover, in each embodiment mentioned above, although the corner | angular part formed by a pair of overhanging pieces 11 and 11 is chamfered in circular arc shape, the corner | angular part is rounded, However, It is not limited to this Needless to say, if it is not desired to round the protruding corner portion of the inner wall, the corner portion formed by the pair of protruding pieces 11 and 11 may be sharpened.

  The corner member of this invention can be utilized when constructing the protruding corner of the inner wall.
