本発明は、壁面の目地部に配置されるジョイナー及びその配置方法に関し、特に建具と壁材との取り合い部に配置されるジョイナー及びその配置方法に関するものである。 The present invention relates to a joiner placed at a joint in a wall surface and a method for arranging the same, and more particularly to a joiner placed at a joint between a fitting and a wall material and a method for arranging the same.

家屋やビルディング等を建設するにあたり、壁に窓を設ける場合、窓枠を構成するサッシ等の建具と壁面を構成するサイディング等の壁材との取り合い部に形成される目地部には、通常、防水のため、シーリングやコーキング等の目地材が充填される。その際、目地材の背面側を支持すると共に目地深さを調節する目的で、ジョイナーと呼ばれる部材を目地部に配置することが従来行われている。このような建具と壁材との取り合い部に配置される従来ジョイナーが、例えば特許文献１に記載されている。 When installing windows in walls when constructing houses, buildings, etc., the joints formed at the joints between fittings such as sashes that make up the window frame and wall materials such as siding that make up the wall surface are usually For waterproofing, joint materials such as sealing and caulking are applied. At that time, a member called a joiner has been conventionally placed at the joint part for the purpose of supporting the back side of the joint material and adjusting the joint depth. A conventional joiner disposed at a joint between such a fitting and a wall material is described in, for example, Patent Document 1.

図５は、特許文献１に記載された従来のジョイナーを用いて構築された壁面構造を示す断面図である。 FIG. 5 is a sectional view showing a wall structure constructed using the conventional joiner described in Patent Document 1.

図５を参照して、特許文献１に記載の従来ジョイナー５は、目地部に沿って延びる長尺状の形態を有し、平板状の固定部５ａとその一端縁部に設けられたコ字型の支持部５ｂとから成り、従って断面が略ひしゃく形状を呈する部材である。 Referring to FIG. 5, the conventional joiner 5 described in Patent Document 1 has an elongated shape extending along the joint part, and has a flat fixing part 5a and a U-shape provided at one end edge thereof. It is a member having a substantially ladle-shaped cross section.

この従来ジョイナー５を用いた壁面構造の構築手順は、壁下地１に形成した開口１ａにサッシ４を配置し、上記の従来ジョイナー５を壁下地１とサッシ４との取り合い部に配置して取り付ける。 The procedure for building a wall structure using this conventional joiner 5 is to place the sash 4 in the opening 1a formed in the wall base 1, and place and attach the conventional joiner 5 at the joint between the wall base 1 and the sash 4. .

ここで従来ジョイナー５の取付手順を説明すると、先ず固定部５ａを壁下地１の表面に配置すると共に、支持部５ｂをサッシ４の側面に粘着剤から成る止水材６を介して当接させることで、従来ジョイナー５の位置決めを行う。次いで、平板状の固定部５ａをビス等で壁下地１に固定すると共に、その上を覆うように防水テープ９を貼り付ける。 Here, to explain the installation procedure of the conventional joiner 5, first, the fixing part 5a is placed on the surface of the wall base 1, and the supporting part 5b is brought into contact with the side surface of the sash 4 via the waterproof material 6 made of adhesive. In this way, the conventional joiner 5 is positioned. Next, the flat fixing part 5a is fixed to the wall base 1 with screws or the like, and a waterproof tape 9 is attached to cover it.

引き続き、壁下地１に固定した取付金具（不図示）で壁材７を壁下地１の表面側に取り付ける。この時、壁材７の側端面を従来ジョイナー５の支持部５ｂの側面に当接させて、壁材７とサッシ４との間に目地部となる離隔を確保する。最後に、サッシ４、従来ジョイナー５の支持部５ｂ、及び壁材７で囲まれた目地部にコーキング等の目地材８を充填して、目的とする壁面構造を得る。 Subsequently, the wall material 7 is attached to the surface side of the wall base 1 using mounting brackets (not shown) fixed to the wall base 1. At this time, the side end surface of the wall material 7 is brought into contact with the side surface of the support portion 5b of the conventional joiner 5 to ensure a separation between the wall material 7 and the sash 4 to form a joint. Finally, the joint portion surrounded by the sash 4, the support portion 5b of the conventional joiner 5, and the wall material 7 is filled with a joint material 8 such as caulking to obtain the desired wall surface structure.

特開２０１７－１７９８７２号公報Japanese Patent Application Publication No. 2017-179872

特許文献１記載の従来ジョイナー５を取り付ける際の位置決めは、固定部５ａを壁下地１の表面に配置すると共に、支持部５ｂをサッシ４の側面に止水材６を介し当接させて行うが、このとき止水材６として粘着剤を用いると、一度位置決め作業を行えば、支持部５ｂがサッシ４に粘着剤で貼り付いてしまうことになる。即ち従来ジョイナー５は、位置決め作業が慎重さを要するため簡単ではなく、しかも位置決め作業後に位置の修正を行うのが難しいという問題があった。 The positioning when attaching the conventional joiner 5 described in Patent Document 1 is performed by placing the fixing part 5a on the surface of the wall base 1 and making the supporting part 5b contact the side surface of the sash 4 via the waterproof material 6. If an adhesive is used as the water stop material 6 at this time, the support portion 5b will be stuck to the sash 4 with the adhesive once the positioning work is performed. That is, the conventional joiner 5 has a problem in that the positioning work is not easy because it requires caution, and furthermore, it is difficult to correct the position after the positioning work.

又、従来ジョイナー５の取り付けには、平板状の固定部５ａをビス等で壁下地１に固定する作業が必要であるため、施工者の作業負担が大きいという問題がある。しかも、この作業負担は、ジョイナーが長くなればなるほどビス打ちの必要数が増えるため増大する。 In addition, in the conventional installation of the joiner 5, it is necessary to fix the flat fixing part 5a to the wall base 1 with screws or the like, so there is a problem that the work burden on the installer is large. Moreover, this work burden increases as the length of the joiner increases because the number of screws required increases.

更に、従来ジョイナー５の固定部５ａは、壁下地１にビス等で固定するため、ある程度の幅寸法が必要であり、これが従来ジョイナー５の小型化、軽量化の支障となっていた。 Further, since the fixing portion 5a of the conventional joiner 5 is fixed to the wall base 1 with screws or the like, it requires a certain width dimension, which has been an obstacle to making the conventional joiner 5 smaller and lighter.

本発明は、上記のような課題を解決するためになされたものであって、ジョイナーの取付時の作業負担を軽減できるジョイナー及びその配置方法を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a joiner and a method for arranging the joiner that can reduce the work burden when installing the joiner.

上記の目的を達成するために、請求項１記載の発明は、建具と壁材との取り合い部に形成される目地部に配置され、目地部に沿って延びる長尺状の形態を有するジョイナーであって、建具の側面に当接し得る平坦な取付面を有する取付部と、取付部の一端から取付面とは反対側へ延びるバックアップ部と、取付部の他端から、取付部に対し鋭角を成して取付面とは反対側へ延びる傾斜部とを備えるものである。 In order to achieve the above object, the invention according to claim 1 provides a joiner having an elongated shape that is disposed at a joint formed in a joint between a fitting and a wall material and extends along the joint. The mounting part has a flat mounting surface that can come into contact with the side surface of the fitting, a backup part that extends from one end of the mounting part to the opposite side of the mounting surface, and a back-up part that extends from the other end of the mounting part at an acute angle to the mounting part. and an inclined portion extending to the opposite side from the mounting surface.

このように構成すると、バックアップ部が目地材の背面側を支持する。取付部の取付面が建具の側面に取り付けられる。取付部と傾斜部とで形成される鋭角の角部が、ジョイナーを取り付ける際の基準位置に当接する。 With this configuration, the backup portion supports the back side of the joint material. The mounting surface of the mounting part is attached to the side of the fitting. An acute corner formed by the attachment part and the inclined part abuts on a reference position when attaching the joiner.

請求項２記載の発明は、請求項１記載の発明の構成において、取付部の取付面に両面テープが配置されているものである。 The invention set forth in claim 2 is the structure of the invention set forth in claim 1, in which a double-sided tape is disposed on the mounting surface of the mounting portion.

このような構成すると、両面テープにより、取付部の取付面が建具の側面に取り付けられる。 With this configuration, the mounting surface of the mounting portion is attached to the side surface of the fitting using double-sided tape.

請求項３記載の発明は、請求項２記載の発明の構成において、バックアップ部の外面とこれに連なる取付面の一部とを含む範囲にボンドブレークテープが配置され、取付面における残余の範囲に両面テープが配置されているものである。 In the invention as claimed in claim 3, in the structure of the invention as claimed in claim 2, the bond break tape is arranged in a range including the outer surface of the backup part and a part of the mounting surface connected thereto, and the bond break tape is arranged in the remaining range on the mounting surface. Double-sided tape is placed on it.

このように構成すると、取付面における目地材に近接する領域にボンドブレークテープが配置される。 With this configuration, the bond break tape is placed in a region of the attachment surface that is close to the joint material.

請求項４記載の発明は、建具と壁材との取り合い部に形成される目地部に、請求項１記載のジョイナーを配置する方法であって、建具の側面に、側面に対し直交する方向へ延びる位置決め部が設けられ、取付部と傾斜部とで形成される角部を建具の側面と位置決め部との境界部に当接させる工程と、傾斜部の外面を位置決め部に当接させて、取付面を建具の側面に対し傾斜して離隔させた状態とする工程とを含むものである。 The invention according to claim 4 is a method of arranging the joiner according to claim 1 at a joint formed in a joining part between a fitting and a wall material, the joiner being placed on a side surface of the fitting in a direction perpendicular to the side surface. an extending positioning part is provided, a step of bringing a corner formed by the mounting part and the inclined part into contact with a boundary between the side surface of the fitting and the positioning part; and bringing an outer surface of the inclined part into contact with the positioning part; This method includes the step of making the mounting surface inclined and spaced apart from the side surface of the fitting.

このように構成すると、ジョイナーの取付面を建具に接触させずに、取付部と傾斜部とで形成される角部を基準として、ジョイナーが位置決めされる。 With this configuration, the joiner is positioned based on the corner formed by the mounting portion and the inclined portion without bringing the mounting surface of the joiner into contact with the fittings.

請求項５記載の発明は、建具と壁材との取り合い部に形成される目地部に、請求項２又は請求項３記載のジョイナーを配置する方法であって、建具の側面に、側面に対し直交する方向へ延びる位置決め部が設けられ、取付部と傾斜部とで形成される角部を建具の側面と位置決め部との境界部に当接させる工程と、傾斜部の外面を位置決め部に当接させて、取付面を建具の側面に対し傾斜して離隔させた状態とする工程と、角部を基準として取付部を回動させて、両面テープの粘着面を建具の側面に貼り付ける工程とを含むものである。 The invention according to claim 5 is a method of arranging the joiner according to claim 2 or 3 at a joint formed in a joint between a fitting and a wall material, the method comprising: A positioning part extending in orthogonal directions is provided, and a step of bringing the corner formed by the mounting part and the inclined part into contact with the boundary between the side surface of the fitting and the positioning part, and bringing the outer surface of the inclined part into contact with the positioning part is performed. A process in which the mounting surface is tilted and separated from the side of the fitting, and a process in which the adhesive side of the double-sided tape is attached to the side of the fitting by rotating the mounting part based on the corner. This includes:

このように構成すると、ジョイナーの取付面に配置した両面テープの粘着面を建具に接触させずに、取付部と傾斜部とで形成される角部を基準として、ジョイナーが位置決めされる。 With this configuration, the joiner is positioned based on the corner formed by the mounting portion and the sloped portion without bringing the adhesive surface of the double-sided tape placed on the mounting surface of the joiner into contact with the fittings.

以上説明したように、請求項１記載の発明によれば、取付部と傾斜部とで形成される角部を所定の基準位置に当接させるという簡単な作業で、建具の側面に対するジョイナーの取付位置を正確に決めることができるから、位置決め作業の負担が軽減される。又、ジョイナーの形態がコンパクトになるから、軽量化及びコストダウンを図れる。 As explained above, according to the invention set forth in claim 1, the joiner can be attached to the side surface of the fitting by a simple operation of bringing the corner formed by the attachment part and the inclined part into contact with a predetermined reference position. Since the position can be determined accurately, the burden of positioning work is reduced. Furthermore, since the shape of the joiner is compact, it is possible to reduce weight and cost.

請求項２記載の発明によれば、請求項１記載の発明の効果に加えて、ジョイナーを位置決めする際に、取付面を建具に接触させない姿勢に維持することで、両面テープが誤って建具の側面に貼り付くのを防止できる。これにより、位置決め作業後にジョイナーの位置の修正が可能となる。又、ジョイナーを建具に取り付ける作業が釘打ちよりも容易になるから、施工能率が向上する。 According to the invention set forth in claim 2, in addition to the effect of the invention set forth in claim 1, when positioning the joiner, by maintaining the mounting surface in a posture that does not contact the fittings, the double-sided tape is prevented from accidentally touching the fittings. Prevents it from sticking to the sides. This makes it possible to correct the position of the joiner after the positioning operation. Furthermore, since the work of attaching the joiner to the fittings is easier than nailing, construction efficiency is improved.

請求項３記載の発明によれば、請求項２記載の発明の効果に加えて、目地材が取付面に接触するのを防止して、ジョイナーと目地材とが一体化するのを回避できる。これにより、目地材の２面接着状態が維持されるので、目地材の長寿命化を図れる。 According to the invention set forth in claim 3, in addition to the effect of the invention set forth in claim 2, it is possible to prevent the joint material from coming into contact with the mounting surface, thereby avoiding integration of the joiner and the joint material. As a result, the two-sided adhesion state of the joint material is maintained, so that the life of the joint material can be extended.

請求項４記載の発明によれば、位置決めの際にジョイナーの取付面を建具と接触させないから、ジョイナー又は建具に粘着剤等が配置されている場合に、両者をくっつかせることがない。これにより、ジョイナーの位置決め作業の実行後に、位置の修正が可能となるから、位置決め作業時の作業者の負担が軽減される。 According to the invention as set forth in claim 4, since the mounting surface of the joiner is not brought into contact with the fitting during positioning, if an adhesive or the like is placed on the joiner or the fitting, the two will not stick together. This makes it possible to correct the position of the joiner after performing the positioning work, thereby reducing the burden on the worker during the positioning work.

請求項５記載の発明によれば、位置決めの際に両面テープの粘着面を建具と接触させないから、ジョイナーと建具とをくっつかせることがない。これにより、ジョイナーの位置決め作業を行った後に、位置の修正が可能となる。位置決め完了後は、取付部を回動させるだけでジョイナーを建具に固定できるから、取付作業が簡単である。 According to the invention as set forth in claim 5, since the adhesive surface of the double-sided tape is not brought into contact with the fitting during positioning, the joiner and the fitting do not come into contact with each other. This allows the position to be corrected after the joiner has been positioned. Once the positioning is complete, the joiner can be fixed to the fittings simply by rotating the mounting part, making the installation process easy.

FIG.

本例のジョイナー１０は、例えばガルバリウム鋼板（登録商標）等の金属板の折り曲げ加工により成形された長尺状の形態を有する部材であって、平坦な取付面１２ａを有する取付部１２と、取付部１２の一端から取付面１２ａとは反対側へ延びるバックアップ部１１と、取付部１２の他端から、取付部１２に対し鋭角を成して取付面１２ａとは反対側へ延びる傾斜部１３とを備える。従って本例のジョイナー１０は、長手方向に直交する方向の断面が、Ｃ字形に近い形態を呈するものとなっている。 The joiner 10 of this example is a member having an elongated shape formed by bending a metal plate such as a galvalume steel plate (registered trademark), and includes a mounting portion 12 having a flat mounting surface 12a, and a mounting portion 12 having a flat mounting surface 12a. A backup portion 11 extends from one end of the portion 12 to the side opposite to the mounting surface 12a, and an inclined portion 13 extends from the other end of the portion 12 to the side opposite to the mounting surface 12a at an acute angle with respect to the mounting portion 12. Equipped with. Accordingly, the joiner 10 of this example has a cross section in a direction perpendicular to the longitudinal direction that is nearly C-shaped.

又、本例のジョイナー１０では、バックアップ部１１の外面とこれに連なる取付面１２ａの一部とを含む範囲にボンドブレークテープ１５が配置され、取付面１２ａにおける残余の範囲に両面テープ１６が配置されている。このように、取付面１２ａにおける目地材に近接する領域をボンドブレークテープで覆うことによって、後述する目地材が取付面１２ａに接触するのを防止することができる。 Further, in the joiner 10 of this example, the bond break tape 15 is arranged in a range that includes the outer surface of the backup part 11 and a part of the mounting surface 12a that is continuous thereto, and the double-sided tape 16 is arranged in the remaining range on the mounting surface 12a. has been done. In this manner, by covering the area of the attachment surface 12a close to the joint material with the bond break tape, it is possible to prevent the joint material described later from coming into contact with the attachment surface 12a.

本例では、バックアップ部１１と取付部１２とが成す角度が直角に設定される。これに対し取付部１２と傾斜部１３とが成す角度αは、９０度未満の鋭角に設定され、好ましくは１０～８０度の範囲に設定される。本例ではα＝８０度である。取付部１２と傾斜部１３との成す角度αを鋭角とすることで、ジョイナー１０を位置決めする際に、建具の側面に対し取付部１２を（９０－α）度傾斜して離隔させた姿勢に維持できるので、両面テープ１６の粘着面が誤って建具にくっつくのを防止できる。又、両面テープ１６の粘着面を建具の側面に当接させる際には、ジョイナー１０の変位がわずかでよいから、施工能率が良い。 In this example, the angle formed by the backup part 11 and the attachment part 12 is set to be a right angle. On the other hand, the angle α formed by the mounting portion 12 and the inclined portion 13 is set to be an acute angle less than 90 degrees, preferably in the range of 10 to 80 degrees. In this example, α=80 degrees. By making the angle α between the mounting part 12 and the inclined part 13 an acute angle, when positioning the joiner 10, the mounting part 12 is tilted (90-α) degrees and separated from the side of the fitting. Since the adhesive side of the double-sided tape 16 can be maintained, it is possible to prevent the adhesive surface of the double-sided tape 16 from accidentally sticking to the fittings. Further, when the adhesive surface of the double-sided tape 16 is brought into contact with the side surface of the fitting, only a slight displacement of the joiner 10 is required, resulting in good construction efficiency.

ところで、バックアップ部１１、取付部１２、及び傾斜部１３それぞれの幅寸法（ジョイナー１０の長手方向とは直交する方向の長さ）は、ジョイナー１０が適用される目地部の大きさや、壁材の寸法等の施工条件に応じ、適宜設定される。本例では、バックアップ部１１、取付部１２、及び傾斜部１３の幅寸法をそれぞれ８ｍｍ、１６ｍｍ、９ｍｍとしたが、これらの数値は一例であり限定されない。 By the way, the width dimensions (lengths in the direction orthogonal to the longitudinal direction of the joiner 10) of each of the backup part 11, the attachment part 12, and the inclined part 13 depend on the size of the joint to which the joiner 10 is applied and the wall material. It is set as appropriate depending on the construction conditions such as dimensions. In this example, the width dimensions of the backup part 11, the attachment part 12, and the inclined part 13 are respectively 8 mm, 16 mm, and 9 mm, but these numerical values are an example and are not limited.

図３は図１に示すジョイナーを用いて構築した壁面構造の一例を示す断面図である。 FIG. 3 is a sectional view showing an example of a wall structure constructed using the joiner shown in FIG. 1.

本例のジョイナー１０は、例えば窓を有する壁面構造Ｗを構築する際に使用される。図３を参照して、この壁面構造Ｗは、壁下地２２に開口２２ａが形成され、この開口２２ａ内に、窓枠となるサッシ等の建具２０が配置される。建具２０の側面２０ａには、この側面２０ａに対し直交する方向へ延びる位置決め部２１が設けられる。位置決め部２１は、壁下地２２の表面に取り付けられて、建具２０の側面２０ａに当接するように配置される部材から成るものでもよいが、建具２０と一体に成形されるものでもよい。そして本例のジョイナー１０が、建具２０と位置決め部２１との取り合いに配置され取り付けられる。更に、壁下地２２に固定した取付金具（不図示）でサイディング等の壁材４０が取り付けられる。その際、壁材４０は、側端面４０ａをジョイナー１０のバックアップ部１１の端縁に当接させるように配置され、壁材４０と建具２０との間に離隔を確保する。そして、建具２０、ジョイナー１０のバックアップ部１１、及び壁材４０で囲まれた目地部３０に、コーキング等の目地材３１が充填され、目的とする壁面構造Ｗが構築される。 The joiner 10 of this example is used, for example, when constructing a wall structure W having a window. Referring to FIG. 3, in this wall structure W, an opening 22a is formed in a wall base 22, and fittings 20 such as a sash serving as a window frame are arranged within this opening 22a. A side surface 20a of the fitting 20 is provided with a positioning portion 21 extending in a direction perpendicular to the side surface 20a. The positioning part 21 may be made of a member that is attached to the surface of the wall base 22 and arranged so as to come into contact with the side surface 20a of the fitting 20, or may be formed integrally with the fitting 20. Then, the joiner 10 of this example is arranged and attached to the fitting 20 and the positioning part 21. Furthermore, a wall material 40 such as siding is attached using mounting brackets (not shown) fixed to the wall base 22. At that time, the wall material 40 is arranged so that the side end surface 40a is brought into contact with the edge of the backup part 11 of the joiner 10, and a separation is ensured between the wall material 40 and the fittings 20. Then, the joint part 30 surrounded by the fittings 20, the backup part 11 of the joiner 10, and the wall material 40 is filled with a joint material 31 such as caulking, and the intended wall structure W is constructed.

図４Ａ～図４Ｃは図１のジョイナーの配置方法を説明する図であって、図４Ａはジョイナーの角部を、建具の側面と位置決め部との境界部に当接させる工程を示す断面図であり、図４Ｂはジョイナーの傾斜部の外面を位置決め部に当接させて、取付面を建具の側面に対し傾斜して離隔させた状態とした工程を示す断面図であり、図４Ｃはジョイナーの角部を基準として取付部を回動させて、両面テープの粘着面を建具の側面に貼り付けた工程を示す断面図である。 4A to 4C are diagrams illustrating a method of arranging the joiner in FIG. 1, and FIG. 4A is a cross-sectional view showing the process of bringing the corner of the joiner into contact with the boundary between the side surface of the fitting and the positioning section. Figure 4B is a cross-sectional view showing the process of bringing the outer surface of the joiner's inclined part into contact with the positioning part so that the mounting surface is inclined and separated from the side surface of the joiner. FIG. 3 is a cross-sectional view showing a process of attaching the adhesive side of the double-sided tape to the side surface of the fitting by rotating the attachment part with reference to the corner.

上述の壁面構造Ｗを構築するに際し、本例のジョイナー１０は、次のような手順で、所定位置に取り付けられる。図４Ａを参照して、壁下地２２の開口２２ａ内に建具２０が配置され、建具２０の側面２０ａに位置決め部２１が設けられた状態で、本例のジョイナー１０を建具２０と位置決め部２１との取り合い部に配置するが、その前に、先ず両面テープ１６の粘着面１７を露出させておく。そして、この状態で、取付部１２と傾斜部１３とで形成される角部１４を、建具２０の側面２０ａと位置決め部２１との境界部２３に当接させる。次いで、図４Ｂを参照して、傾斜部１３の外面が位置決め部２１に当接した状態となるように、ジョイナー１０の姿勢を保持する。これにより、取付面１２ａが建具２０の側面２０ａに対し、（９０－α）度の角度で傾斜して離隔した状態となる。これらの作業は、角部１４の外隅形状を境界部２３の内隅形状に合わせるだけなので、両者の位置合わせを容易に行うことができる。しかも、この位置決め作業の間、両面テープ１６の粘着面１７を建具２０と接触させないから、ジョイナー１０が建具２０に誤ってくっついてしまうことがない。これにより、位置決め作業を一度行った後に、ジョイナー１０の位置を修正することが可能となる。 When constructing the above-mentioned wall surface structure W, the joiner 10 of this example is attached to a predetermined position in the following procedure. Referring to FIG. 4A, the joiner 10 of this example is connected to the fitting 20 and the positioning part 21 in a state where the fitting 20 is arranged in the opening 22a of the wall base 22 and the positioning part 21 is provided on the side surface 20a of the fitting 20. The adhesive surface 17 of the double-sided tape 16 is first exposed before placing it on the joining part of the double-sided tape 16. In this state, the corner portion 14 formed by the mounting portion 12 and the inclined portion 13 is brought into contact with the boundary portion 23 between the side surface 20a of the fitting 20 and the positioning portion 21. Next, referring to FIG. 4B, the posture of the joiner 10 is maintained such that the outer surface of the inclined portion 13 is in contact with the positioning portion 21. As a result, the mounting surface 12a is inclined at an angle of (90-α) degrees and separated from the side surface 20a of the fitting 20. These operations simply align the outer corner shape of the corner portion 14 with the inner corner shape of the boundary portion 23, so that alignment of both can be easily performed. Moreover, since the adhesive surface 17 of the double-sided tape 16 is not brought into contact with the fitting 20 during this positioning work, the joiner 10 will not accidentally stick to the fitting 20. This allows the position of the joiner 10 to be corrected after the positioning work has been performed once.

図４Ｃを参照して、上述のようにして位置決め作業が完了したならば、角部１４を中心としてジョイナー１０を回動させ、取付部１２の粘着面１７を建具２０の側面２０ａに圧接させる。これによりジョイナー１０が建具２０に対し所定の位置に固定されることとなる。 Referring to FIG. 4C, once the positioning work is completed as described above, the joiner 10 is rotated around the corner 14 to press the adhesive surface 17 of the attachment part 12 against the side surface 20a of the fitting 20. As a result, the joiner 10 is fixed at a predetermined position relative to the fitting 20.

再び図３を参照して、ジョイナー１０の取り付けが完了したならば、壁下地２２に固定した取付金具（不図示）を用いて壁材４０を取り付けた後、建具２０と壁材４０との取り合い部に形成される目地部３０にコーキング等の目地材３１を充填する。 Referring again to FIG. 3, once the installation of the joiner 10 is completed, the wall material 40 is attached using the mounting brackets (not shown) fixed to the wall base 22, and then the connection between the joiner 20 and the wall material 40 is completed. A joint material 31 such as caulking is filled into the joint portion 30 formed in the section.

本例のジョイナー１０は、バックアップ部１１の外面とこれに連なる取付面１２ａの一部とを含む範囲にボンドブレークテープ１５が配置され、バックアップ部１１の外面と共に、取付面１２ａにおける目地材３１に近接する領域がボンドブレークテープ１５によって覆われた構成となっている。これにより、目地部３０に充填した目地材３１が、取付面１２ａと建具２０の側面２０ａとの隙間に浸入したとしても、目地材３１とジョイナー１０との接触を防止することができる。即ち、ジョイナー１０と目地材３１とが一体化するのを回避して、目地材３１の２面接着状態を維持することができるから、目地材３１の長寿命化を図れる。 In the joiner 10 of this example, the bond break tape 15 is arranged in a range that includes the outer surface of the backup part 11 and a part of the mounting surface 12a that is connected thereto, and is attached to the joint material 31 on the mounting surface 12a together with the outer surface of the backup part 11. Adjacent areas are covered with bond break tape 15. Thereby, even if the joint material 31 filled in the joint portion 30 enters the gap between the mounting surface 12a and the side surface 20a of the fitting 20, contact between the joint material 31 and the joiner 10 can be prevented. That is, it is possible to avoid the joiner 10 and the joint material 31 from being integrated and maintain the two-sided adhesive state of the joint material 31, so that the life of the joint material 31 can be extended.

取付面１２ａにおけるボンドブレークテープ１５の貼り付け幅Ｌ（図２参照）は、目地材３１が浸入する可能性の有る長さ以上であって、両面テープ１６の配置範囲を不必要に狭めないことが望ましく、例えば１０ｍｍ以下の範囲で設定するとよい。 The pasting width L (see FIG. 2) of the bond break tape 15 on the mounting surface 12a should be at least a length that allows the joint material 31 to penetrate, and should not unnecessarily narrow the placement range of the double-sided tape 16. It is desirable that the distance be set within a range of 10 mm or less, for example.

以上を要するに、本例のジョイナー１０によれば、角部１４を基準として建具２０に対する取り付け位置を正確に決めることができるため、位置決め作業が容易である。位置決めの際に両面テープ１６の粘着面１７を建具２０に接触させないから、位置決め作業後にジョイナー１０の取付位置を修正することが可能である。ジョイナー１０の建具２０に対する固定作業は、従来の釘打ちよりも遥かに容易なので、施工能率が向上する。このように本例のジョイナー１０は、施工時の作業負担を軽減する効果を発揮するものである。又、特許文献１に記載されるような従来ジョイナーと比較して、本例のジョイナー１０は形態が簡素化され小型化されるので、軽量化及びコストダウンを図れるという効果を発揮する。更に、ボンドブレークテープ１５を取付面１２ａの一部にも配置したので、ジョイナー１０と目地材３１との一体化が阻止され、目地材３１の長寿命化を図れる等、本例のジョイナー１０は多くの優れた利点を有するものである。 In summary, according to the joiner 10 of this example, the attachment position to the joiner 20 can be accurately determined using the corner 14 as a reference, so the positioning work is easy. Since the adhesive surface 17 of the double-sided tape 16 is not brought into contact with the fittings 20 during positioning, it is possible to correct the mounting position of the joiner 10 after the positioning work. The work of fixing the joiner 10 to the fittings 20 is much easier than conventional nailing, so construction efficiency is improved. In this way, the joiner 10 of this example exhibits the effect of reducing the work burden during construction. Moreover, compared to the conventional joiner as described in Patent Document 1, the joiner 10 of this example has a simplified form and is smaller in size, so it exhibits the effect of reducing weight and cost. Furthermore, since the bond break tape 15 is also placed on a part of the mounting surface 12a, the joiner 10 and the joint material 31 are prevented from being integrated, and the life of the joint material 31 can be extended. It has many excellent advantages.

尚、上記の実施の形態では、ジョイナーはガルバリウム鋼板の折り曲げ加工で成形したが、他の表面加工を施した鋼板で成形してもよく、鋼板以外の、アルミニウム、銅、又はこれらの合金等の非鉄系金属を用いてもよい。折り曲げ加工法以外に、押し出し加工法や引き抜き加工法を用いてもよい。 In the above embodiment, the joiner is formed by bending a galvalume steel plate, but it may be formed from a steel plate with other surface treatments, and may be formed from a steel plate other than steel plate, such as aluminum, copper, or an alloy thereof. Non-ferrous metals may also be used. In addition to the bending method, an extrusion method or a drawing method may be used.

又、上記の実施の形態では、ジョイナーの各部の幅寸法は、（取付部）＞（傾斜部）＞（バックアップ部）という大小関係となっていたが、バックアップ部又は傾斜部の幅寸法が最大となるように形成してもよい。又、これらの幅寸法の比率は適宜変更してもよい。 Further, in the above embodiment, the width dimensions of each part of the joiner have a size relationship of (attachment part) > (slope part) > (backup part), but the width dimension of the backup part or the slope part is the largest. It may be formed as follows. Further, the ratio of these width dimensions may be changed as appropriate.

更に、上記の実施の形態では、ジョイナーの取付対象となる建具は、窓を形成するためのサッシであったが、建築物の出入口を構成するためのドア枠であってもよい。或いはジョイナーの取付対象となる建具が、枠部材以外の、出隅部材や入隅部材であってもよい。 Furthermore, in the above embodiment, the fitting to which the joiner is attached is a sash for forming a window, but it may also be a door frame for forming an entrance/exit of a building. Alternatively, the fitting to which the joiner is attached may be an out-corner member or an in-corner member other than the frame member.

更に、上記の実施の形態では、ボンドブレークテープをジョイナーの取付面の一部にも配置したが、ボンドブレークテープはバックアップ部だけに配置して、取付面を覆わない構成としてもよい。或いは、ジョイナーの取付面の一部に貼り付けたボンドブレークテープの上に、両面テープを重ね貼りしてもよい。 Further, in the above embodiment, the bond break tape is also placed on a part of the attachment surface of the joiner, but the bond break tape may be placed only on the backup part and not cover the attachment surface. Alternatively, double-sided tape may be applied over the bond break tape applied to a part of the attachment surface of the joiner.

更に、上記の実施の形態では、ボンドブレークテープと両面テープとの間に隙間を設けているが、両者が連続するように配置してもよい。 Further, in the above embodiment, a gap is provided between the bond break tape and the double-sided tape, but they may be arranged so that they are continuous.

更に、上記の実施の形態では、ジョイナーの取付面に両面テープを配置したが、これを省略してもよい。この場合、建具の側面に両面テープを配置してもよい。或いは、ジョイナーの建具に対する取り付けを、接着剤や釘打ちで行ってもよい。 Further, in the above embodiment, double-sided tape is placed on the mounting surface of the joiner, but this may be omitted. In this case, double-sided tape may be placed on the side of the fittings. Alternatively, the joiner may be attached to the fittings using adhesive or nailing.

更に、上記の実施の形態では、ジョイナーの角部を位置決め部に直接当接させているが、壁材と壁下地との間隔が大きい場合などには、ジョイナーと位置決め部材との間に、所定厚みを有する位置調整部材を挿入してもよい。これにより、ジョイナーの取付位置を、目地部の奥行方向に調整することが可能となる。 Furthermore, in the above embodiment, the corner of the joiner is brought into direct contact with the positioning member, but if the distance between the wall material and the wall base is large, a predetermined distance between the joiner and the positioning member may be used. A position adjusting member having a thickness may be inserted. This makes it possible to adjust the attachment position of the joiner in the depth direction of the joint.
