モルタル面に亀裂が入る事がある。When painting walls with mortar or other coating materials, cracks may appear on the mortar surface due to drying shrinkage of the hardened mortar. In addition, when attaching base plates to wooden or iron pillars, etc., or when the base plates are not continuous with each other with molded base plates such as ALC boards, cracks may appear in the hardened mortar surface depending on the movement of the base. .

。For this reason, work is performed to create joints for the purpose of dividing the continuous mortar surface into areas of a certain size or less. It is common practice today to make joints on flat parts.
Joint materials such as those shown in FIGS. 4(a), (b), and (c) are used. The materials shown in Figures 4 (a) and (b) are used in the form of being embedded in mortar.
The material shown in Figure (C) is used in such a manner that the joint material is removed after applying mortar or after the mortar has hardened. The joint materials shown in FIGS. 4(a) and 4(b) are made of synthetic resin or metal, and the joint material shown in FIG. 4(C) is made of wood, polystyrene foam, or the like. Parts of the corners of walls are prone to cracks, but the current situation is that there are mainly gaps in the walls, and the joints have not been properly treated.
現在、コーナ一部分には、施工能率を上げる事を目的と

体を形成する事となり、独立壁体を形成する目地部分に
はなり得ない。Currently, in order to increase construction efficiency, embedded type fixed timber with a cross section as shown in Fig. 5(a) is used in a part of the corner. This is used in the manner shown in FIG. 5(b), and the mortar 6 applied to a part of the corner of the wall 5 forms a continuous body and cannot become a joint part forming an independent wall.
美観よりも亀裂発生を重視する場合、コーナー部に近い

部の亀裂が防止できる方法は現在まで開発されていない
。As described above, no method has been developed to date that can prevent cracks in the mortar while maintaining the aesthetic appearance and making the construction easier when applying mortar to a portion of the corner of a wall.
本発明の目的は、このような課題を解決する事のできる
コーナー用の埋込み目地定木を得る事である。An object of the present invention is to obtain an embedded joint setting tree for corners that can solve such problems.
本発明は、上記目的を達成するためになされたものであ

各底板の外面には、側板が凹設され、さらに底板の前記
接合部の外側に、側板が凸段されている事を特徴とする
左官用目地定木である。The present invention has been made to achieve the above object, and its gist is that two rectangular bottom plates are joined at right angles,
This joint setting board for plastering is characterized in that a side plate is recessed on the outer surface of each bottom plate, and further, the side plate is stepped on the outside of the joint portion of the bottom plate.

又は薄いものにしておいて、施工の際、そこを折り曲げ
て使用してもよい。FIG. 1 shows a perspective view of an example of the joint setting tree of the present invention. The shape illustrated in Fig. 1 only needs to be maintained at the time of applying mortar, so for example, as shown in Fig. 2, do not join the two bottom plates at right angles in advance; The portion 7 may be made softer or thinner than the bottom plate 1 and the side plates 2, and may be bent during construction.

), it can be attached directly to a corner of the wall. The joint material can be attached to the wall surface depending on the material of the base, for example, by nailing in the case of a wooden base, or by mortar, etc. in the case of a concrete base. When attaching with adhesive such as mortar, it is advisable to provide an appropriate size and number of holes in the bottom plate.
次に、第３図（Ｃ）に示すように、外側の側板２の中央
側には、モルタル等の塗り材が、側板の高さまで塗られ

る。Next, as shown in FIG. 3(C), a coating material such as mortar is applied to the center of the outer side plate 2 up to the height of the side plate. Since there is a side plate, mortar can be applied easily and beautifully.
外側側板のコーナー側には、目地材７′を充填する。目
地材は、定木に付着し弾力性を６′する材料を用いる。The corner side of the outer side plate is filled with joint material 7'. The joint material used is a material that adheres to the fixed tree and has 6' elasticity.

色にする事により、目立たなくする事もできるし、色調
、色艶等を変えて、意匠性をもたせる事もできる。The joints can be made less noticeable by using the same color as the coating material (or its finishing material), or they can be made more decorative by changing the color tone, color gloss, etc.
本願発明の目地定木は、第４図や第５図に示される公知
の埋め込み定木と同様に、塩化ビニル樹脂など合成樹脂
で作成できるが、金属製であってもよい。The joint tree of the present invention can be made of synthetic resin such as vinyl chloride resin, similar to the known embedded tree shown in FIGS. 4 and 5, but it may also be made of metal.
また、第２図に示す折り曲げ型の目地定木は、例えば金
属製の定木とし、折り曲げ部分は、厚さを変え（薄くす

（ｆｆｉ合度）を変えた材料を使用する事により、折り
曲げ易くする事ができる。Furthermore, when extrusion molding of synthetic resin is used, bending can be made easier by making a V cut on the back side of the folded part or by using a material with a different softness (ffi degree) only in the folded part.
しかし、第２図の形状のものが７の部分を折り曲げる事
により容易に第１図の形状を保てるようになればよいの
で、特に、材質は限定されない。However, the material is not particularly limited as long as the shape shown in FIG. 2 can easily maintain the shape shown in FIG. 1 by bending the portion 7.

生が防止できると考えられる。[Function] As shown in Fig. 3 (C), a joint material 7' is interposed between one wall and the other wall at a part of the corner of the wall, so that stress in one wall is transferred to the other wall. Because it does not affect the wall,
Since each wall exists as an independent wall surface, it is thought that the occurrence of cracks can be prevented.
