Description
本発明は、壁、天井または床の仕上げ工事等、建築構造物の内装工事において、壁の角部と天井（床）との継ぎ目（見切部）に設けられる見切材および見切材の取付方法に関する。 The present invention relates to a parting material provided at a joint (parting part) between a corner of a wall and a ceiling (floor) and a method for attaching the parting material in interior construction of a building structure such as finishing work of a wall, ceiling, or floor. .
一般的に、建築構造物の壁、天井にクロスや塗装等の仕上げを行う際、壁の仕上げ面と天井の仕上げ面の継ぎ目（見切部）の仕上げ方法として、主に廻縁方式、突付け方式、見切材方式等が使用されている。
廻縁方式は見切部に木材等で形成された長尺状の廻縁を取り付ける方法であり、突付け方式は壁の仕上げ面と天井の仕上げ面を突き付けることで廻縁等の部材を使用せずに施工する方法である。見切材方式とは、壁の仕上げ面と天井または床の仕上げ面の継ぎ目を美しく収めるために見切材を取り付けて使用する方法である。
また、壁の仕上げ面と床の仕上げ面の継ぎ目（見切部）の仕上げ方法に関しては、長尺状の横板である巾木を見切部に使用する方法が主として使用されている。
しかしながら、壁と天井の見切部を仕上げる場合、廻縁方式は廻縁が目立つため狭い空間に不向きであり、突付け方式は目切部に隙間を設けないように施工するのが困難である等の理由によって、見切部をシンプルに仕上げることができかつ簡単に施工可能な見切材方式を使用することが多くなってきた。
また、壁と床の見切部の仕上げ方法においても、壁と天井の見切部と同様に簡単に施工できる見切材方式に注目が高まっている。
In general, when finishing a wall or ceiling of a building structure with a cross or paint, as a finishing method for the seam (parting part) between the finished surface of the wall and the finished surface of the ceiling, it is mainly a marginal method, butting The method, parting material method, etc. are used.
The peripheral edge method is a method of attaching a long peripheral edge made of wood or the like to the parting part, and the thrusting method uses a member such as a peripheral edge by abutting the finished surface of the wall and the finished surface of the ceiling. It is a method to construct without. The parting material method is a method in which a parting material is attached and used in order to beautifully fit the seam between the finished surface of the wall and the finished surface of the ceiling or floor.
As a method for finishing the seam (parting part) between the finished surface of the wall and the finished surface of the floor, a method of using the baseboard, which is a long horizontal plate, in the parting part is mainly used.
However, when finishing the wall and ceiling parting, the edge method is not suitable for narrow spaces because the edge is conspicuous, and the bumping method is difficult to construct so that there is no gap in the parting part. For this reason, a parting material system that can simply finish the parting part and can be easily constructed has been increasingly used.
Also, in the finishing method for the wall and floor parting, attention is being paid to the parting material system that can be easily constructed in the same manner as the wall and ceiling parting.
このような見切材としては様々なものが提案されている。
特許文献１は、不燃下地材および出隅の内装化粧構造に関するものであり、不燃下地材３０は、天井材の厚さ相当の肉厚を有する第１の袖板部３１と、第１の袖板部３１より肉薄の第２の袖板部３２を備え、天井材の見切部に配されて野縁に対してビス止めされるものである。
特許文献２および３は、内装用見切縁材に関するものであり、長尺かつ平面視で長方形状の見切縁材を見切部に取り付けるものである。
Various kinds of parting materials have been proposed.
Patent Document 1 relates to a non-combustible base material and an interior decorative structure of a corner, and the non-combustible base material 30 includes a first sleeve plate portion 31 having a thickness corresponding to the thickness of a ceiling material, and a first sleeve. A second sleeve plate portion 32 that is thinner than the plate portion 31 is provided, and the second sleeve plate portion 32 is disposed at a parting portion of the ceiling material and is screwed to the edge.
Patent Documents 2 and 3 relate to a parting material for interior use, and are attached to a parting part having a long and rectangular shape in plan view.
しかしながら、壁と天井（床）が平らである場合は、特許文献１，２，３の不燃下地材や内装用見切縁材を適切に使用することが可能であるが、円弧状の壁の角部等、壁や天井（床）の仕上げ面が曲面である場合には、前述の不燃下地材や内装用見切縁材を曲面に取り付けることが難しいうえ、壁の曲面と不燃下地材や内装用見切縁材との間に隙間１００があいてしまい、見た目が悪く見切部の美観性を大きく損ねてしまう（図１０）。廻縁方式や巾木を使用する方法を使用したとしても、壁の曲面の見切部に対して廻縁や巾木を湾曲させて取り付けることが大変困難で、作業効率が著しく低下してしまう。
さらに、壁が曲面である場合は、壁と天井（床）の継ぎ目（見切部）に極力隙間があかないように天井板（床板）を壁の曲面に沿ったＲ形状に切断する必要があるが、天井板（床板）をＲ形状に切断する加工は大変煩雑でかつ熟練した技術が必要となるため、作業性が著しく損なわれる結果となってしまう。
However, when the wall and the ceiling (floor) are flat, the incombustible base material and interior parting material of Patent Documents 1, 2, and 3 can be used appropriately, but the corners of the arc-shaped wall If the finished surface of the wall or ceiling (floor), such as a wall, is curved, it is difficult to attach the above-mentioned incombustible base material or interior trim material to the curved surface, and the curved surface of the wall and incombustible base material or interior There is a gap 100 between the parting edge material and the appearance is poor, and the aesthetics of the parting part are greatly impaired (FIG. 10). Even if the method of using the peripheral edge method or the baseboard is used, it is very difficult to bend and attach the peripheral edge or the baseboard to the part of the curved surface of the wall, and the working efficiency is remarkably lowered.
Furthermore, when the wall is a curved surface, it is necessary to cut the ceiling board (floor board) into an R shape along the curved surface of the wall so that there is no gap as much as possible at the joint (parting part) between the wall and the ceiling (floor). However, the process of cutting the ceiling board (floor board) into an R shape is very cumbersome and requires a skillful technique, resulting in a significant loss of workability.
そこで、本願出願人は鋭意検討を重ねた結果、円弧状の内側面を備えかつ壁の角部と天井（床）の隙間全体を被覆して保護するための厚みが形成された保護部を有する見切材を使用することで、壁の仕上げ面が曲面であった場合でも、壁の曲面と見切材との間に隙間が形成されることがなく、また天井板（床板）を壁の曲面に沿ったＲ形状に切断しなくても壁と天井（床）の継ぎ目（見切部）にできる隙間を見切材によって被覆して隠すことが可能であることに着目し、発明するに至った。 Therefore, the applicant of the present application has intensively studied, and as a result, has a protective portion having an arc-shaped inner surface and a thickness for covering and protecting the entire gap between the corner of the wall and the ceiling (floor). By using a parting material, no gap is formed between the curved surface of the wall and the parting material even if the finished surface of the wall is a curved surface, and the ceiling panel (floor board) is made into a curved surface of the wall. Focusing on the fact that it is possible to cover and hide the gap formed in the seam (parting part) between the wall and the ceiling (floor) without cutting into an R shape along the line, it has been invented.
本発明の目的は、円弧状の壁の角部と天井（床）の継ぎ目（見切部）においても、壁の角部への取り付けが簡単で、さらに天井板（床板）の加工が不要であり、美観に優れた見切材および見切材の取付方法を提供することを目的とする。 The object of the present invention is that it is easy to attach to the corner of the wall at the joint between the corner of the arc-shaped wall and the ceiling (floor) (partition), and further, the processing of the ceiling (floor) is unnecessary. An object of the present invention is to provide a parting material excellent in aesthetic appearance and a method for attaching the parting material.
本発明は、円弧状の壁の角部と天井または円弧状の壁の角部と床に設けられる見切材であって、前記壁の角部と前記天井または前記壁の角部と前記床の隙間全体を被覆して保護するための厚みが形成された保護部と、前記保護部の両端に設けられた保護部両端部を備えたことを特徴とする。
本発明によれば、厚みが形成された保護部を有する見切材を使用することで前記保護部によって壁の角部と天井（床）の隙間全体を被覆することが可能であるため天井板（床板）を壁の曲面に沿ったＲ形状に切断しなくても壁の角部と天井（床）の隙間は見切材によって被覆かつ保護される。見切部の美観性を保ち、隙間周辺を見切材によって補強することが可能で、内装工事の作業効率を向上することが可能となる。

見切材本体５の外側面１０ｂは、壁の角部Ｍから突出して設けられる側の側面であり、断面が略直角状（Ｌ字状）に形成されている。見切材本体５の外側面１０ｂが直角状であるのは、見切材本体５のうち最大の厚みを有する箇所（厚み１ｄ）をなるべく厚く形成することで見切材本体５によって円弧状の壁の角部Ｍと天井（床）Ｃとの隙間全体を被覆できるようにするためである。外側面１０ｂが直角状であると、隙間全体を被覆できる利点に加えて、製造を簡素化することができる。
ここで、見切材本体５の外側面１０ｂの断面が略直角状（Ｌ字状）であるとしたが、製造時の誤差等により直角状の頂点にわずかな円弧形状（曲率半径１ｍｍ以下）を含むことがある。
見切材本体５は、樹脂、金属、不燃材等の材質で形成されている。見切材本体５が可撓性を有する樹脂であれば、壁の角部Ｍの曲面の曲率半径と見切材本体５の内側面の曲率半径が同一でない場合であっても、見切材本体５の変形により曲率半径の違いを吸収することが可能となり、見切材１を密着して壁の角部Ｍに添設することができる。
また見切材本体５に不燃材等の材質を使用した場合は、建築構造物の内部の耐火性能を向上することが可能となる。
The parting material body 5 is a member that covers and protects the gap between the corner M of the arc-shaped wall and the ceiling (floor) and complements the gap, and is entirely L-shaped. It is attached to the parting part so that the upper surface is closely attached to the ceiling (floor) across the corner part M.
The parting material body 5 is formed in a protective part 1 having a sufficient thickness 1d for covering the gap, and is continuously provided at both ends of the protective part 1 so as to be smaller than the thickness 1d of the protective part 1 (thickness 2d). A pair of both ends 2 and 2 of the protection part is formed, and a pair of attachment parts 3 and 3 for attaching other parting materials are provided at the other ends of the both ends 2 and 2 of the protection part.
Since the parting material main body 5 is attached in close contact with the corner portion M of the arc-shaped wall, the central position of the inner side surface 10a on the side attached to the corner portion M of the wall is formed in an arc shape.
The radius of curvature at the center position of the inner surface 10a is formed in the range of 10 mm to 15 mm. In the building structure, when the corner M of the wall has a circular arc shape (when the corner M of the wall has a curved surface), the radius of curvature of the corner M of the wall is in the range of 10 mm to 15 mm. caused by. Depending on the difference in the radius of curvature of the corner M of the wall, several types of parting materials having different radii of curvature of the inner surface 10a may be used.
The outer surface 10b of the parting material main body 5 is a side surface provided to protrude from the corner portion M of the wall, and the cross section is formed in a substantially right angle (L shape). The reason why the outer surface 10b of the parting material body 5 is right-angled is that the part having the maximum thickness (thickness 1d) in the parting material body 5 is formed as thick as possible so that the corner of the arc-shaped wall is formed by the parting material body 5. This is because the entire gap between the part M and the ceiling (floor) C can be covered. When the outer side surface 10b has a right-angled shape, in addition to the advantage that the entire gap can be covered, the manufacturing can be simplified.
Here, although the cross section of the outer surface 10b of the parting material body 5 is substantially right-angled (L-shaped), a slight arc shape (curvature radius of 1 mm or less) is formed at the right-angled apex due to errors in manufacturing. May contain.
The parting material body 5 is made of a material such as resin, metal, or non-combustible material. If the parting material body 5 is a resin having flexibility, even if the curvature radius of the curved surface of the corner portion M of the wall and the curvature radius of the inner surface of the parting material body 5 are not the same, the parting material body 5 It becomes possible to absorb the difference in the radius of curvature by the deformation, and the parting material 1 can be closely attached and attached to the corner M of the wall.
Moreover, when materials, such as a noncombustible material, are used for the parting material main body 5, it becomes possible to improve the fire resistance inside a building structure.
保護部１は、見切材本体５の中心周辺の領域を指し、壁の角部Ｍの頂点に取り付けられ、壁の角部Ｍと天井（床）との隙間全体を被覆できるように十分な厚み１ｄをもって形成される。
保護部１の内側面は断面円弧状であり、保護部１の外側面は断面直角状であるため、保護部１の中心位置（直角状の外側面の頂点の位置）が一番厚く（厚み１ｄ）、両端に向けて徐々に厚みが薄くなっている。
保護部１の両端には、保護部１の両端から連続して一対の保護部両端部２，２が設けられている。
保護部両端部２，２は、見切材本体５の両端周辺の領域を指し、壁の角部Ｍの頂点を挟んだ状態で取り付けられ、保護部両端部２，２の端部には、他の見切材４を取り付けるための一対の取付部３，３が設けられる。
保護部両端部２，２の内側面は断面直線状であり保護部１の外側面も断面直線状であるため、保護部両端部２，２は略同一の厚み２ｄで形成され、保護部１の厚み１ｄよりも小さい厚み２ｄとなっている。保護部両端部２，２の厚み２ｄは、見切材１０を使用する際に端部に他の見切材４を取り付けるため（図７）、他の見切材４の幅と略同一で、かつなるべく目立たない大きさとする。好適には、２ｍｍ〜５ｍｍの厚みであることが望ましい。
The protective part 1 refers to a region around the center of the parting material body 5, is attached to the apex of the corner M of the wall, and has a thickness sufficient to cover the entire gap between the corner M of the wall and the ceiling (floor). It is formed with 1d.
Since the inner surface of the protective part 1 has an arc shape in cross section and the outer surface of the protective part 1 has a right angle in cross section, the center position of the protective part 1 (the position of the vertex of the right outer surface) is the thickest (thickness). 1d), the thickness gradually decreases toward both ends.
At both ends of the protection unit 1, a pair of protection unit end portions 2 and 2 are provided continuously from both ends of the protection unit 1.
The protection part both end parts 2 and 2 indicate regions around both ends of the parting material body 5 and are attached with the apex of the corner part M of the wall sandwiched between them. A pair of attachment portions 3 and 3 for attaching the parting material 4 is provided.
Since the inner side surfaces of both ends 2 and 2 of the protection part are linear in cross section and the outer side surface of the protection part 1 is also linear in cross section, both ends 2 and 2 of the protection part are formed with substantially the same thickness 2d. The thickness 2d is smaller than the thickness 1d. The thickness 2d of the protection part both ends 2 and 2 is substantially the same as the width of the other parting material 4 and is preferably as much as possible in order to attach the other parting material 4 to the end when using the parting material 10 (FIG. 7). The size is inconspicuous. Preferably, the thickness is 2 mm to 5 mm.
図６は、本発明の見切材を壁の角部と天井との継ぎ目（見切部）に適用する前を示す模式図である。
従来、円弧状の壁の角部Ｍと天井（床）の継ぎ目（目切部）において隙間Ｗが存在すると、美観性の問題や気密性等の問題が発生するため、天井板（床板）を壁の角部Ｍに沿うように円弧状に切断する必要があった。しかしながら、天井板（床板）を円弧状に切断する作業は大変煩雑でかつ熟練した技術が必要となるため、作業性が著しく損なわれてしまう。
本発明では、天井板（床板）と壁の角部Ｍの接合箇所において、天井板（床板）は円弧状に切断せずに、壁の角部Ｍの両端の平面状の壁に沿うように直線状に切断し、天井板（床板）と壁の角部Ｍに隙間Ｗを形成する。そして、隙間Ｗ全体を被覆することが可能な厚み１ｄをもつ見切材１０を使用して、隙間Ｗ全体を被覆することで、隙間Ｗを外部から視認できないようにする。隙間Ｗ全体を被覆するためには、保護部１は十分な厚み１ｄをもって形成される必要があるが、保護部１の内側面の曲率半径が壁の角部Ｍの曲率半径と略同一で、かつ隙間Ｗが天井板（床板）を壁の角部Ｍの両端の平面状の壁に沿うように直線状に切断したことによってできた隙間であれば、保護部１の外側面は平面状の壁に平行な２直線で形成された形状であるため、隙間Ｗ全体を被覆することが可能な厚み１ｄを形成することができる。
このように見切材１０の形状を工夫することにより、壁の角部への取り付けが簡単で、さらに天井板（床板）の加工が不要であり、美観に優れた見切材を提供することが可能となる。
FIG. 6 is a schematic view showing a state before the parting material of the present invention is applied to the joint (parting part) between the corner of the wall and the ceiling.
Conventionally, if there is a gap W between the corner portion M of the arc-shaped wall and the joint (cutting portion) between the ceiling (floor), problems such as aesthetics and airtightness occur. It was necessary to cut in a circular arc shape along the corner M of the wall. However, the work of cutting the ceiling board (floor board) into an arc shape is very complicated and requires a skillful technique, so that workability is significantly impaired.
In the present invention, the ceiling plate (floor plate) is not cut into a circular arc shape at the junction between the ceiling plate (floor plate) and the corner portion M of the wall, but along the planar walls at both ends of the corner portion M of the wall. Cut in a straight line and form a gap W between the ceiling board (floor board) and the corner M of the wall. Then, by using the parting material 10 having a thickness 1d that can cover the entire gap W, the gap W is made invisible from the outside by covering the entire gap W. In order to cover the entire gap W, the protective portion 1 needs to be formed with a sufficient thickness 1d, but the radius of curvature of the inner surface of the protective portion 1 is substantially the same as the radius of curvature of the corner portion M of the wall, If the gap W is a gap formed by cutting the ceiling board (floor board) linearly along the flat walls at both ends of the corner M of the wall, the outer surface of the protection part 1 is planar. Since the shape is formed by two straight lines parallel to the wall, a thickness 1d that can cover the entire gap W can be formed.
By devising the shape of the parting material 10 in this way, it is easy to attach to the corner of the wall, and further, it is not necessary to process the ceiling board (floor board), and it is possible to provide a parting material excellent in aesthetics. It becomes.

(Second Embodiment)
FIG. 13 is a perspective view showing a parting material according to the second embodiment of the present invention, and FIG. 14 is a plan view of the parting material according to the second embodiment.
The parting material 10 of the first embodiment has a cross section of the outer side surface 10b formed in a right angle (L shape), whereas the parting material 20 of the second embodiment of the present invention has an outer side surface 10d. Is different in that it is formed in an arc shape. Since the other configurations are the same, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.
本実施の形態の見切材２０は、壁、天井または床の仕上げ工事等、建築構造物の内装工事において、壁の角部と天井（床）との継ぎ目（見切部）に取り付けられる部材であり、壁の角部Ｍに添設される保護部１と保護部１の両端に連続して設けられて壁に添設される一対の保護部両端部２，２を備えた見切材本体５と、見切材本体５の両端に設けられた一対の取付部３，３を備える（図１３、図１４）。
見切材本体５の外側面１０ｄは、壁の角部Ｍから突出して設けられる側の側面であり、断面が円弧状に形成されている。
The parting material 20 according to the present embodiment is a member that is attached to a joint (parting part) between a corner of a wall and a ceiling (floor) in an interior construction work of a building structure such as a wall, ceiling, or floor finishing work. A parting material body 5 provided with a protective part 1 attached to a corner M of the wall and a pair of protective part both ends 2, 2 provided continuously at both ends of the protective part 1 and attached to the wall; A pair of attachment portions 3 and 3 provided at both ends of the parting material body 5 are provided (FIGS. 13 and 14).
The outer surface 10d of the parting material body 5 is a side surface provided to protrude from the corner portion M of the wall, and the cross section is formed in an arc shape.
図１５は、上記第２の実施形態の見切材の保護部両端部と内側面の曲率半径の関係を示す説明図であり、（ａ）は保護部両端部の厚み２ｄが５ｍｍの場合、（ｂ）は保護部両端部の厚み２ｄが３．５ｍｍの場合、（ｃ）は保護部両端部の厚み２ｄが２ｍｍの場合であり、図１６は、上記第２の実施形態の見切材の保護部両端部と内側面の曲率半径の関係を示す説明図２である。
見切材２０が壁の角部Ｍと天井（床）との隙間Ｗ全体を被覆するためには、見切材本体５の外側面１０ｄの曲率半径ｒと保護部両端部２，２の厚み２ｄの関係が重要となる。
隙間Ｗが壁の角部Ｍの両端に設けられた平面状の壁に沿って天井板を直線状に切断することによって形成されるとすると、隙間Ｗの頂点の座標を（０，０）とし、保護部両端部２，２の内側面１０ａはＸ軸上およびＹ軸上にあって、保護部両端部２，２の外側面は、厚み２ｄ＝Ｄとして、ｘ＝Ｄおよびｙ＝Ｄの直線上にあると仮定する（図１６）。
上述のように仮定すると、見切材本体５の外側面１０ｄは、隙間Ｗの頂点の座標（０，０）を通り、かつｘ＝Ｄおよびｙ＝Ｄを接線とする円の一部である場合に隙間Ｗ全体を被覆可能となり、その場合の曲率半径をｒ（０，０）とすると、ｒ（０，０）を閾値として、ｒ（０，０）よりも曲率半径ｒが大きい場合は隙間Ｗの全体を被覆できず、ｒ（０，０）よりも曲率半径ｒが小さい場合は隙間Ｗの全体を被覆可能となる。
上述の条件を代入すると、ｒ（０，０）は以下の（数１）となり、以下の（数２）のように、曲率半径ｒが保護部両端部２，２の厚み２ｄ（Ｄ）の約３倍以内であれば、隙間Ｗの全体を被覆することが可能となる。
FIG. 15 is an explanatory view showing the relationship between the radius of curvature of the protector both ends and the inner surface of the parting material of the second embodiment, and (a) is a case where the thickness 2d of both ends of the protector is 5 mm. FIG. 16B shows the case where the thickness 2d of both ends of the protective portion is 3.5 mm, FIG. 16C shows the case where the thickness 2d of both ends of the protective portion is 2 mm, and FIG. 16 shows the protection of the parting material according to the second embodiment. It is explanatory drawing 2 which shows the relationship between the curvature radius of a both-ends part and an inner surface.
In order for the parting material 20 to cover the entire gap W between the corner M of the wall and the ceiling (floor), the radius of curvature r of the outer surface 10d of the parting material body 5 and the thickness 2d of the both ends 2 and 2 of the protection part Relationships are important.
If the gap W is formed by cutting the ceiling plate in a straight line along the planar walls provided at both ends of the corner M of the wall, the coordinates of the apex of the gap W are (0, 0). The inner side surfaces 10a of the protective part both ends 2 and 2 are on the X axis and the Y axis, and the outer side surfaces of the protective part both end parts 2 and 2 have thicknesses 2d = D and x = D and y = D. Assume that it is on a straight line (FIG. 16).
Assuming as described above, the outer surface 10d of the parting material body 5 passes through the coordinates (0, 0) of the apex of the gap W, and is a part of a circle tangent to x = D and y = D. It allows covering the entire gap W, when the curvature radius of the case and r (0,0), as a threshold a r (0,0), gap is large radius of curvature r than r (0,0) If the entire W cannot be covered and the radius of curvature r is smaller than r (0, 0) , the entire gap W can be covered.
Substituting the above conditions, r (0, 0) becomes the following ( Equation 1), and the radius of curvature r is equal to the thickness 2d (D) of the protection portion both ends 2 and 2 as shown in the following ( Equation 2). If it is within about 3 times, the entire gap W can be covered.
保護部両端部２の厚みが５ｍｍの場合（図１５（ａ））、見切材２０の外側面１０ｄの曲率半径Ｒは１５ｍｍ以内であれば、隙間Ｗ全体を見切材２０で被覆することが可能であり、保護部両端部２の厚みが３．５ｍｍの場合（図１５（ｂ））、見切材２０の外側面１０ｄの曲率半径Ｒは１０．５ｍｍ以内であれば、隙間Ｗ全体を見切材２０で被覆することが可能である。また、保護部両端部２の厚みが２ｍｍの場合（図１５（ｃ））、見切材２０の外側面１０ｄの曲率半径Ｒは６ｍｍ以内であれば、隙間Ｗ全体を見切材２０で被覆することが可能である。 When the thickness of both ends 2 of the protection part is 5 mm (FIG. 15A), the entire gap W can be covered with the parting material 20 if the radius of curvature R of the outer surface 10d of the parting material 20 is within 15 mm. When the thickness of both ends 2 of the protective part is 3.5 mm (FIG. 15 (b)), if the radius of curvature R of the outer surface 10d of the parting material 20 is within 10.5 mm, the entire gap W is parted. It is possible to coat with 20. In addition, when the thickness of both ends 2 of the protective part is 2 mm (FIG. 15C), the entire gap W is covered with the parting material 20 if the curvature radius R of the outer surface 10d of the parting material 20 is within 6 mm. Is possible.
このように見切材の外側面が円弧状である場合でも、壁の角部Ｍと天井（床）との隙間Ｗ全体を被覆可能な外側面の曲率半径を見切材の保護部両端部の厚み２ｄ（Ｄ）との関係を考慮して設計することで、壁の角部Ｍと天井（床）の隙間全体を被覆することが可能であり、見切部の美観性を保ち、隙間周辺を見切材によって補強することが可能で、内装工事の作業効率を向上することが可能となる。 Thus, even when the outer side surface of the parting material is arcuate, the radius of curvature of the outer side surface that can cover the entire gap W between the corner M of the wall and the ceiling (floor) is the thickness of both ends of the protective part of the parting material. By designing in consideration of the relationship with 2d (D), it is possible to cover the entire gap between the corner M of the wall and the ceiling (floor), keeping the aesthetics of the parting part and giving up the part around the gap. It can be reinforced by the material, and the work efficiency of the interior work can be improved.
