Description
本発明は、室内の壁に湾曲部を有する非矩形状の開口部を形成するための開口枠及びそれを備えた開口部構造に関するものである。 The present invention relates to an opening frame for forming a non-rectangular opening with a curved portion in an interior wall, and an opening structure equipped with the same.
従来、住宅等の室内の壁に、アーチ型等の非矩形状の開口部が形成されることがある(例えば、下記の特許文献1を参照)。この種の非矩形状の開口部には、曲げ合板等、予め開口形状に成形された開口枠を準備して施工現場に搬送し、施工していた。 Conventionally, non-rectangular openings, such as arch-shaped openings, have been formed in interior walls of houses and the like (see, for example, Patent Document 1 below). For this type of non-rectangular opening, an opening frame made of bent plywood or the like that has been pre-formed into the opening shape has been prepared, transported to the construction site, and then constructed.
しかしながら、予め非矩形状の開口形状に成形された開口枠を用いる場合、施工現場において壁下地材の切り欠きの周縁にぴったりと沿うように、精度良く開口形状に成形する(曲げ合板の場合、曲げる)必要がある。そのため、従来の手法では、開口枠の準備に手間がかかり、また、開口枠施工後に開口枠に化粧を施す必要があるがその作業も容易ではないため、非矩形状の開口部を容易に形成できないという問題があった。 However, when using an opening frame that has been pre-formed into a non-rectangular opening shape, it must be precisely formed into the opening shape (bent plywood, for example) so that it fits snugly around the periphery of the cutout in the wall base material at the construction site. As a result, with conventional methods, preparing the opening frame is time-consuming, and the opening frame needs to be finished after construction, but this work is not easy, meaning that it is not easy to form a non-rectangular opening.
本発明は斯かる点に鑑みてなされたもので、その目的は、室内の壁に非矩形状の開口部を容易に形成できるようにすることにある。 The present invention was made in consideration of these points, and its purpose is to make it easier to form non-rectangular openings in interior walls.
上記の目的を達成するために、本発明では、一対の壁下地材の切り欠きの周縁に沿って延びて該一対の壁下地材間を遮蔽する板状の枠本体部を、軟質材料で人の手で変形可能に構成することとした。 In order to achieve the above objective, the present invention provides a plate-shaped frame body that extends along the periphery of the cutouts in a pair of wall base materials to provide shielding between the pair of wall base materials, and is constructed from a soft material so that it can be deformed by hand.
具体的には、第1の発明は、壁に形成された非矩形状の開口部を縁取る開口枠を前提とするものである。 Specifically, the first invention is based on an opening frame that borders a non-rectangular opening formed in a wall.
そして、第1の発明は、上記開口部となる切り欠きが形成された上記壁の一部を構成する一対の壁下地材の上記切り欠きの周縁に沿って延び、該一対の壁下地材間を遮蔽する板状の枠本体部と、上記一対の壁下地材間に挿入されて該一対の壁下地材に固定され、上記枠本体部を支持する支持部とを備え、上記枠本体部は、第1の軟質材料で人の手で変形可能に構成されていることを特徴とするものである。 The first invention is characterized in that it comprises a plate-shaped frame body portion that extends along the periphery of the cutout of a pair of wall base materials that constitute a part of the wall in which the cutout that becomes the opening is formed, shielding the space between the pair of wall base materials, and a support portion that is inserted between the pair of wall base materials and fixed to the pair of wall base materials, supporting the frame body portion, and that the frame body portion is made of a first soft material and is configured to be deformable by hand.
ここで、「第1の軟質材料」とは、枠本体部を人の手で変形可能に構成することができる材料を言い、例えば、合成樹脂材料や天然樹脂材料等の弾性を有する材料を用いることができる。 Here, the "first soft material" refers to a material that allows the frame body to be deformed by hand, and may be, for example, a material with elasticity such as a synthetic resin material or a natural resin material.
第1の発明では、非矩形状の開口部の開口形状に形成されて該開口部を縁取る板状の枠本体部が、第1の軟質材料で人の手で変形可能に構成されている。そのため、施工現場において枠本体部を一対の壁下地材の切り欠きの周縁に沿って延びるように変形させながら、一対の壁下地材の切り欠きの周縁に施工することができる。従って、第1の発明によれば、非矩形状の開口部の開口形状に形成されて該開口部を縁取る板状の枠本体部を、予め開口形状に成形しておくことなく、施工現場で変形させながら容易に一対の壁下地材の切り欠きの周縁にぴったりと沿うように精度良く施工することができる。 In the first invention, the plate-shaped frame body portion that is formed into the opening shape of the non-rectangular opening and borders the opening is made of a first soft material and is configured to be deformable by hand. Therefore, the frame body portion can be deformed so as to extend along the periphery of the cutouts in the pair of wall base materials at the construction site, and then installed on the periphery of the cutouts in the pair of wall base materials. Therefore, according to the first invention, the plate-shaped frame body portion that is formed into the opening shape of the non-rectangular opening and borders the opening can be deformed at the construction site and easily installed with high precision so as to fit closely to the periphery of the cutouts in the pair of wall base materials, without having to be molded into the opening shape in advance.
第2の発明は、第1の発明において、上記支持部は、上記枠本体部の片側の面から突出して該枠本体部の長手方向に延び、上記第1の軟質材料と同一又は異なる部材である第2の軟質材料で、上記枠本体部と一体に且つ人の手で変形可能に構成されていることを特徴とするものである。 The second invention is the first invention, characterized in that the support portion protrudes from one side of the frame body portion and extends in the longitudinal direction of the frame body portion, is made of a second soft material that is the same as or different from the first soft material, and is configured to be integral with the frame body portion and deformable by hand.
ここで、「第2の軟質材料」とは、支持部を人の手で変形可能に構成することができる材料を言い、例えば、合成樹脂材料や天然樹脂材料等の弾性を有する材料を用いることができる。 Here, the "second soft material" refers to a material that allows the support part to be deformed by hand, and for example, a material having elasticity such as a synthetic resin material or a natural resin material can be used.
また、「枠本体部と一体に構成」とは、射出成形で一体成形してもよく、個別に成形した後に接着・融着・溶着等によって固着させて一体化させてもよい。 In addition, "integrally formed with the frame main body" may mean integrally formed by injection molding, or may be molded separately and then integrated by bonding, fusion, welding, etc.
第2の発明では、支持部も枠本体部と同様に長い部材で構成されているが、枠本体部と同様に、第2の軟質材料で人の手で変形可能に構成されている。また、支持部は枠本体部と一体に構成されている。そのため、施工現場において枠本体部及び支持部を一対の壁下地材の切り欠きの周縁に沿って延びるように変形させながら、支持部を一対の壁下地材間に挿入して支持部を両壁下地材に固定することにより、容易に開口枠を施工することができる。従って、第2の発明によれば、非矩形状の開口部の開口形状に形成されて該開口部を縁取る開口枠を、施工現場で変形させながら容易に非矩形状の開口部の周縁にぴったりと沿うように精度良く施工することができる。 In the second invention, the support part is also made of a long member like the frame body part, but like the frame body part, it is made of a second soft material and is deformable by hand. The support part is also integrally formed with the frame body part. Therefore, the opening frame can be easily constructed by deforming the frame body part and the support part so that they extend along the periphery of the cutouts in the pair of wall base materials at the construction site, inserting the support part between the pair of wall base materials and fixing the support part to both wall base materials. Therefore, according to the second invention, the opening frame that is formed in the opening shape of the non-rectangular opening and borders the opening can be easily constructed with high precision so as to fit closely to the periphery of the non-rectangular opening while being deformed at the construction site.
第3の発明は、第2の発明において、上記支持部は、上記枠本体部の上記片側の面からそれぞれ突出して該枠本体部の長手方向に互いに平行に延びる一対の板状の脚部からなることを特徴とするものである。 The third invention is the second invention, characterized in that the support portion comprises a pair of plate-shaped legs each protruding from one side of the frame body portion and extending parallel to each other in the longitudinal direction of the frame body portion.
第3の発明では、支持部が一対の板状の脚部からなる。このような構成によれば、一対の壁下地材に固定して枠本体部を支持する支持部を、必要最小限の分量の第2の軟質材料で軽量に且つ変形し易く構成することができる。 In the third invention, the support part is made up of a pair of plate-shaped legs. With this configuration, the support part that is fixed to a pair of wall base materials and supports the frame main body part can be made lightweight and easily deformed using the minimum necessary amount of the second soft material.
第4の発明は、第1の発明において、上記支持部は、上記枠本体部とは別体に構成され、上記枠本体部と上記支持部とには、互いに係合する係合部がそれぞれ設けられ、上記枠本体部及び上記支持部の上記係合部は、互いに係合させると、上記枠本体部が上記支持部に取り付けられて支持されるように構成されていることを特徴とするものである。 The fourth invention is the first invention, characterized in that the support part is configured separately from the frame main body part, the frame main body part and the support part are each provided with an engagement part that engages with each other, and the engagement parts of the frame main body part and the support part are configured such that, when engaged with each other, the frame main body part is attached to and supported by the support part.
第4の発明では、支持部が枠本体部とは別体に構成され、係合部どうしを係合させるだけで、支持部に容易に枠本体部を取り付けることができるように構成されている。このような構成によれば、支持部を先に一対の壁下地材に挿入して固定し、固定された支持部に枠本体部を取り付けることにより、開口枠を容易に施工することができる。 In the fourth invention, the support parts are constructed separately from the frame main body part, and the frame main body part can be easily attached to the support parts by simply engaging the engagement parts. With this configuration, the opening frame can be easily constructed by first inserting and fixing the support parts into a pair of wall base materials, and then attaching the frame main body part to the fixed support parts.
第5の発明は、第4の発明において、上記支持部は、上記第1の軟質材料と同一又は異なる部材である第2の軟質材料で人の手で変形可能に構成され、上記一対の壁下地材間に挿入されて上記切り欠きの外周に沿って延びていることを特徴とするものである。 The fifth invention is the fourth invention, characterized in that the support part is made of a second soft material that is the same as or different from the first soft material, is manually deformable, and is inserted between the pair of wall base materials and extends along the outer periphery of the cutout.
第5の発明では、支持部も枠本体部と同様に長い部材で構成されているが、枠本体部と同様に、第2の軟質材料で人の手で変形可能に構成されている。そのため、施工現場において支持部を容易に変形させることができるため、支持部を変形させながら一対の壁下地材間に挿入することにより、容易に一対の壁下地材の切り欠きの外周に沿うように配置することができる。第5の発明によれば、施工現場において、非矩形状の開口部を縁取る開口枠を、容易に、非矩形状の開口部の周縁にぴったりと沿うように精度良く施工することができる。 In the fifth invention, the support part is also composed of a long member like the frame main body part, but like the frame main body part, it is composed of a second soft material that can be deformed by hand. Therefore, the support part can be easily deformed at the construction site, and by inserting the support part between a pair of wall base materials while deforming it, it can be easily positioned so that it fits along the outer periphery of the cutouts in the pair of wall base materials. According to the fifth invention, an opening frame that borders a non-rectangular opening can be easily and precisely constructed at the construction site so that it fits closely to the periphery of the non-rectangular opening.
第6の発明は、第1~第5のいずれか1つの発明において、上記支持部は、上記一対の壁下地材の内面と当接する2つの外面を有し、上記各外面の少なくとも一部は、凹凸形状に形成されていることを特徴とするものである。 The sixth invention is any one of the first to fifth inventions, characterized in that the support portion has two outer surfaces that abut against the inner surfaces of the pair of wall base materials, and at least a portion of each of the outer surfaces is formed in an uneven shape.
第6の発明では、一対の壁下地材間に挿入されて一対の壁下地材の内面と当接する支持部の2つの外面の少なくとも一部が、凹凸形状に形成されている。そのため、支持部が一対の壁下地材間に挿入された際に、支持部の外面と壁下地材の内面との摩擦抵抗が増大し、支持部が一対の壁下地材にひっかかり易くなる。そのため、一対の壁下地材に支持部を固定する際に、支持部がずれるのを抑制することができ、固定作業が容易になる。 In the sixth invention, at least a portion of the two outer surfaces of the support part that is inserted between a pair of wall base materials and abuts against the inner surfaces of the pair of wall base materials is formed with an uneven shape. Therefore, when the support part is inserted between the pair of wall base materials, the frictional resistance between the outer surface of the support part and the inner surface of the wall base material increases, making it easier for the support part to get caught on the pair of wall base materials. Therefore, when the support part is fixed to the pair of wall base materials, it is possible to prevent the support part from shifting, making the fixing work easier.
第7の発明は、壁に非矩形状の開口部を形成する開口部構造であって、上記開口部となる切り欠きが形成された上記壁の一部を構成する一対の壁下地材と、上記開口部を縁取る開口枠とを備え、上記開口枠は、第1~第5のいずれか1つの発明に係る開口枠であることを特徴とするものである。 The seventh invention is an opening structure that forms a non-rectangular opening in a wall, and is characterized in that it comprises a pair of wall base materials that constitute a part of the wall in which a cutout that becomes the opening is formed, and an opening frame that borders the opening, and the opening frame is an opening frame according to any one of the first to fifth inventions.
第7の発明によれば、第1~第5のいずれか1つの発明に係る開口枠を備えているため、壁に非矩形状の開口部を容易に形成することができる。 According to the seventh aspect of the invention, since the opening frame according to any one of the first to fifth aspects of the invention is provided, it is possible to easily form a non-rectangular opening in a wall.
以上説明した如く、本発明によると、一対の壁下地材の切り欠きの周縁に沿って延びて該一対の壁下地材間を遮蔽する板状の枠本体部を、軟質材料で人の手で変形可能に構成したため、室内の壁に非矩形状の開口部を容易に形成することができる。 As described above, according to the present invention, the plate-shaped frame body that extends along the periphery of the cutouts in a pair of wall base materials and shields the space between the pair of wall base materials is made of a soft material and is manually deformable, making it easy to form a non-rectangular opening in the wall inside the room.
以下、本発明の実施形態を図面に基づいて詳細に説明する。以下の実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものでは全くない。 The following describes in detail the embodiments of the present invention with reference to the drawings. The following description of the embodiments is merely exemplary in nature and is in no way intended to limit the present invention, its applications, or its uses.
《発明の実施形態1》
-開口部構造の概略構成-
図1に示すように、開口部構造1は、住宅等の建物の室内の壁Wに非矩形状の開口部2を形成するものである。なお、本実施形態1では、非矩形状の開口部2の一例としてアーチ型の開口部2を形成する例について説明する。以下では、説明の便宜上、図1の上側、下側、左側、右側を、それぞれ「上」、「下」、「左」、「右」として説明する。また、図1の紙面直交方向において手前側を「前」、奥側を「後」として説明する。
First Embodiment of the Invention
-Outline of the opening structure-
As shown in Fig. 1, the opening structure 1 forms a non-rectangular opening 2 in a wall W inside a building such as a house. In this embodiment 1, an example of forming an arch-shaped opening 2 will be described as an example of a non-rectangular opening 2. For convenience of description, the upper side, lower side, left side, and right side of Fig. 1 will be described as "upper", "lower", "left", and "right", respectively. Also, the near side in the direction perpendicular to the paper surface of Fig. 1 will be described as "front" and the far side as "rear".
図1及び図2に示すように、開口部構造1は、開口部2となる切り欠き3がそれぞれ形成され、壁Wの一部を構成する一対の壁下地材10,10と、開口部2を縁取る開口枠20とを備えている。 As shown in Figures 1 and 2, the opening structure 1 includes a pair of wall base materials 10, 10 that form part of a wall W, each of which has a notch 3 that becomes an opening 2, and an opening frame 20 that borders the opening 2.
〔壁下地材〕
壁下地材10は、複数の石膏ボード11~13でアーチ形状に加工されている。本実施形態1では、壁下地材10は、半円形状の切り欠きが形成された上部石膏ボード11と、2つの矩形状で長尺の側部石膏ボード12,13とで構成されている。石膏ボード11~13は、上部石膏ボード11の左右の下端に、2つの側部石膏ボード12,13が連続して下方に延びるように配置され、柱やまぐさ等の躯体(図示省略)にビス等で固定されている。壁下地材10は、3つの石膏ボード11~13を上述のように配置して躯体に固定することにより、アーチ形状に形成されている。
[Wall underlayment material]
The wall base material 10 is processed into an arch shape by a plurality of gypsum boards 11 to 13. In the present embodiment 1, the wall base material 10 is composed of an upper gypsum board 11 with a semicircular cutout formed therein, and two rectangular and long side gypsum boards 12 and 13. The gypsum boards 11 to 13 are arranged so that the two side gypsum boards 12 and 13 extend continuously downward from the left and right lower ends of the upper gypsum board 11, and are fixed to a framework (not shown) such as a pillar or lintel with screws or the like. The wall base material 10 is formed into an arch shape by arranging the three gypsum boards 11 to 13 as described above and fixing them to the framework.
一対の壁下地材10,10は、躯体の前側と後側とにそれぞれ施工され、大壁構造の壁Wの一部を構成している。一対の壁下地材10,10は、切り欠き3の外周縁部に、後述する開口枠20の支持部22を挿入するための挿入代(空間)が形成されるように、躯体の開口部2側の端面より挿入代分だけ突出するように施工されている。 A pair of wall base materials 10, 10 are installed on the front and rear sides of the structure, respectively, and form part of the wall W of the large wall structure. The pair of wall base materials 10, 10 are installed so that they protrude by an insertion allowance from the end face of the structure on the opening 2 side, so that an insertion allowance (space) is formed on the outer peripheral edge of the cutout 3 for inserting the support part 22 of the opening frame 20 described later.
図3に示すように、本実施形態1では、一対の壁下地材10,10の化粧面(前側の壁下地材10の前面、後側の壁下地材10の後面)には、クロスCが施工されている。 As shown in FIG. 3, in this embodiment 1, cloth C is applied to the decorative surfaces of a pair of wall base materials 10, 10 (the front surface of the front wall base material 10 and the rear surface of the rear wall base material 10).
〔開口枠〕
図3及び図4に示すように、開口枠20は、一対の壁下地材10,10間を遮蔽する板状の枠本体部21と、枠本体部21を支持する支持部22とを備えている。枠本体部21は、ポリ塩化ビニルを主材料とする樹脂材料(第1の軟質材料)で人の手で変形可能に構成されている。また、支持部22も、ポリ塩化ビニルを主材料とする樹脂材料(第2の軟質材料)で人の手で変形可能に構成されている。本実施形態1では、枠本体部21と支持部22とは、射出成形により一体に構成されている。
[Opening frame]
As shown in Figures 3 and 4, the opening frame 20 includes a plate-shaped frame body 21 that shields the space between a pair of wall base materials 10, 10, and a support portion 22 that supports the frame body 21. The frame body 21 is made of a resin material (first soft material) mainly made of polyvinyl chloride so as to be deformable by hand. The support portion 22 is also made of a resin material (second soft material) mainly made of polyvinyl chloride so as to be deformable by hand. In this embodiment 1, the frame body 21 and the support portion 22 are integrally formed by injection molding.
枠本体部21は、幅狭で薄い長尺の矩形状の板状部分である。枠本体部21は、一対の壁下地材10,10間を遮蔽するように、一対の壁下地材10,10の切り欠き3,3の周縁に沿って切り欠き3,3の周縁の一端部(左端部)3aから他端部(右端部)3bに亘って延びている。枠本体部21は、このように設けられて開口部2を縁取っている。 The frame body 21 is a narrow, thin, long rectangular plate-like portion. The frame body 21 extends from one end (left end) 3a to the other end (right end) 3b of the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 along the periphery of the notches 3, 3 so as to shield the space between the pair of wall base materials 10, 10. The frame body 21 is thus arranged to frame the opening 2.
枠本体部21の幅は、一対の壁下地材10,10間を遮蔽すると共に、一対の壁下地材10,10の開口部2側の端面を遮蔽するように、開口部2の前側の壁下地材10の前面から後側の壁下地材の後面に亘る長さに形成されている。なお、本実施形態1では、枠本体部21の幅は、壁Wの厚みよりも4~10mm程度長く形成されている。そのため、枠本体部21は、壁Wの前面及び後面よりも前後にそれぞれ2~5mm程度(好ましくは3mm以上)突出している。このように枠本体部21の幅を壁Wの厚みよりも長くすることにより、見切材を用いることなくクロスC等の化粧材を止めることができる。また、枠本体部21の突出部にクロスCをぶつけてカットすることで、クロスCの端部が目立ち難くなり、端部処理が容易になる。 The width of the frame body 21 is formed to a length that extends from the front surface of the wall base material 10 on the front side of the opening 2 to the rear surface of the wall base material on the rear side so as to shield the space between the pair of wall base materials 10, 10 and to shield the end faces of the pair of wall base materials 10, 10 on the opening 2 side. In this embodiment 1, the width of the frame body 21 is formed to be about 4 to 10 mm longer than the thickness of the wall W. Therefore, the frame body 21 protrudes about 2 to 5 mm (preferably 3 mm or more) forward and backward from the front and rear surfaces of the wall W. By making the width of the frame body 21 longer than the thickness of the wall W in this way, decorative materials such as the cloth C can be secured without using a trim material. In addition, by hitting the cloth C against the protruding part of the frame body 21 and cutting it, the end of the cloth C becomes less noticeable and the end processing becomes easier.
枠本体部21の厚みは、例えば、2~5mm程度に形成されている。なお、枠本体部21の厚みは、人の手で枠本体部21を一対の壁下地材10,10の切り欠き3,3の周縁に沿って湾曲させることができる厚みであればよく、枠本体部21を構成する材料に応じて変更すればよい。 The thickness of the frame body 21 is, for example, about 2 to 5 mm. The thickness of the frame body 21 may be any thickness that allows the frame body 21 to be bent manually along the periphery of the cutouts 3, 3 of the pair of wall base materials 10, 10, and may be changed depending on the material that constitutes the frame body 21.
枠本体部21の長さは、一対の壁下地材10,10の切り欠き3,3の周縁の一端部(左端部)3aから他端部(右端部)3bに亘る長さに形成されている。 The length of the frame body 21 is formed to extend from one end (left end) 3a to the other end (right end) 3b of the periphery of the notches 3, 3 of a pair of wall base materials 10, 10.
なお、本実施形態1では、図1に示すように、一対の壁下地材10,10の下端部には巾木4,4が設けられている。巾木4,4は、前側の壁下地材10から後側の壁下地材10へ折り曲げられながら連続して延びるように施工されている。そのため、一対の壁下地材10,10間の下端部は、巾木4,4によって遮蔽されている。 In this embodiment 1, as shown in FIG. 1, a baseboard 4 is provided at the lower end of a pair of wall base materials 10. The baseboard 4 is installed so that it extends continuously from the front wall base material 10 to the rear wall base material 10 while being bent. Therefore, the lower end between the pair of wall base materials 10 is shielded by the baseboard 4.
以上のように巾木4,4が設けられることにより、本実施形態1では、枠本体部21は、切り欠き3,3の周縁の一端部(左端部)3aの巾木4の上端から他端部(右端部)3bの巾木4の上端に亘る長さに形成されている。なお、巾木4,4は必ずしも設けられていなくてもよく、巾木4,4が設けられない場合、枠本体部21は、切り欠き3,3の周縁の床に接する一端から同様に床に接する他端に亘って延びる長さに形成すればよい。 By providing the baseboards 4, 4 as described above, in this embodiment 1, the frame body 21 is formed to a length extending from the top end of the baseboard 4 at one end (left end) 3a of the periphery of the notches 3, 3 to the top end of the baseboard 4 at the other end (right end) 3b. Note that the baseboards 4, 4 do not necessarily have to be provided, and if the baseboards 4, 4 are not provided, the frame body 21 may be formed to a length extending from one end of the periphery of the notches 3, 3 that contacts the floor to the other end that also contacts the floor.
なお、本実施形態1では、施工現場で切断することにより、枠本体部21の長さは、一対の壁下地材10,10の切り欠き3,3の周縁の一端部(左端部)3aの巾木4の上端から他端部(右端部)3bの巾木4の上端に亘る長さに形成される。 In this embodiment 1, the length of the frame body 21 is formed by cutting at the construction site to a length that extends from the upper end of the baseboard 4 at one end (left end) 3a of the periphery of the notches 3, 3 of a pair of wall base materials 10, 10 to the upper end of the baseboard 4 at the other end (right end) 3b.
支持部22は、枠本体部21の片側の面から突出して枠本体部21の長手方向に互いに平行に延びる一対の板状の脚部23,23によって構成されている。一対の脚部23,23は、同様に構成されている。一対の脚部23,23は、一対の壁下地材10,10間に挿入された際に、外面23a,23aが一対の壁下地材10,10の内面に当接するように、外面23a,23a間の距離が一対の壁下地材10,10の内面間の距離と等しい又は僅かに大きい長さになるように形成されている。 The support section 22 is composed of a pair of plate-shaped legs 23, 23 that protrude from one side of the frame body section 21 and extend parallel to each other in the longitudinal direction of the frame body section 21. The pair of legs 23, 23 are similarly constructed. The pair of legs 23, 23 are formed so that the distance between the outer surfaces 23a, 23a is equal to or slightly greater than the distance between the inner surfaces of the pair of wall base materials 10, 10, so that the outer surfaces 23a, 23a abut against the inner surfaces of the pair of wall base materials 10, 10 when the pair of legs 23, 23 are inserted between the pair of wall base materials 10, 10.
脚部23は、幅狭で薄い長尺の矩形状の板状部分である。脚部23の幅(突出高さ)は、20~40mm程度に形成されている。脚部23の厚みは、3~7mm程度に形成されている。脚部23の長さは、枠本体部21の長さ方向の一端から他端に亘る長さ(即ち、本実施形態1では、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3aの巾木4の上端から他端部3bの巾木4の上端に亘る長さ)に形成されている。 The leg 23 is a long, narrow, thin rectangular plate-like portion. The width (protruding height) of the leg 23 is formed to be approximately 20 to 40 mm. The thickness of the leg 23 is formed to be approximately 3 to 7 mm. The length of the leg 23 is formed to be a length extending from one end to the other end in the longitudinal direction of the frame main body 21 (i.e., in this embodiment 1, the length extending from the upper end of the baseboard 4 at one end 3a of the periphery of the notches 3, 3 of a pair of wall base materials 10, 10 to the upper end of the baseboard 4 at the other end 3b).
また、脚部23の外面23aの少なくとも一部には、複数本の線条突起23b,…,23bが形成されている。線条突起23bは、脚部23の外面23aから僅かに突起し、脚部23の長手方向の一端から他端に亘って(即ち、枠本体部21の長さ方向の一端から他端に亘って)延びている。このような複数本の線条突起23b,…,23bにより、脚部23の外面23aの少なくとも一部は、凹凸形状に形成されている。 In addition, multiple linear protrusions 23b, ..., 23b are formed on at least a portion of the outer surface 23a of the leg 23. The linear protrusions 23b protrude slightly from the outer surface 23a of the leg 23 and extend from one end to the other end in the longitudinal direction of the leg 23 (i.e., from one end to the other end in the longitudinal direction of the frame main body 21). Due to these multiple linear protrusions 23b, ..., 23b, at least a portion of the outer surface 23a of the leg 23 is formed into an uneven shape.
支持部22(一対の脚部23,23)は、一対の壁下地材10,10間に挿入され、2つの外面23a,23aが一対の壁下地材10,10の内面に当接した状態で、ビス30,30によって一対の壁下地材10,10に固定されている。 The support portion 22 (a pair of legs 23, 23) is inserted between a pair of wall base materials 10, 10, and is fixed to the pair of wall base materials 10, 10 by screws 30, 30 with the two outer surfaces 23a, 23a abutting the inner surfaces of the pair of wall base materials 10, 10.
-開口部構造の施工方法-
次に、開口部構造1の施工方法について説明する。
- Opening structure construction method -
Next, a construction method for the opening structure 1 will be described.
まず、一対の壁下地材10,10を施工する。柱やまぐさ等の躯体(図示省略)の前側及び後側のそれぞれに、3つの石膏ボード11~13を、上部石膏ボード11の左右の下端に、2つの側部石膏ボード12,13が連続して下方に延びるように配置し、それぞれ躯体にビス等で固定する。これにより、アーチ形状の一対の壁下地材10,10が施工される。 First, a pair of wall base materials 10, 10 are installed. Three gypsum boards 11-13 are placed on the front and rear of a structure (not shown) such as pillars and lintels, and two side gypsum boards 12, 13 are placed on the left and right lower ends of the upper gypsum board 11 so that they extend continuously downward, and each is fixed to the structure with screws or the like. This completes the installation of a pair of arch-shaped wall base materials 10, 10.
次に、一対の壁下地材10,10の下端部に巾木4,4を施工する。巾木4,4は、前側の壁下地材10から後側の壁下地材10へ折り曲げられながら連続して延び、ビス等で壁下地材10に固定される。一対の壁下地材10,10間の下端部は、巾木4,4によって遮蔽される。 Next, baseboards 4, 4 are installed on the lower ends of the pair of wall base materials 10, 10. The baseboards 4, 4 extend continuously while being bent from the front wall base material 10 to the rear wall base material 10, and are fixed to the wall base material 10 with screws or the like. The lower end between the pair of wall base materials 10, 10 is shielded by the baseboards 4, 4.
次に、開口枠20を施工する。 Next, the opening frame 20 is constructed.
まず、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3a側から他端部3b側へ(逆も可)、順に支持部22(一対の脚部23,23)を一対の壁下地材10,10間に挿入していく。なお、上述のように、本実施形態1では、一対の壁下地材10,10の下端部には巾木4,4が設けられ、一対の壁下地材10,10間の下端部は、巾木4,4によって遮蔽されている。そのため、本実施形態1では、一対の壁下地材10,10の切り欠き3,3の周縁の一端部(左端部)3aの巾木4の上端から他端部(右端部)3bの巾木4の上端に亘り、支持部22(一対の脚部23,23)を挿入する。 First, the support part 22 (a pair of legs 23, 23) is inserted between the pair of wall base materials 10, 10 in sequence from one end 3a side to the other end 3b side of the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 (or vice versa). As described above, in this embodiment 1, baseboards 4, 4 are provided at the lower ends of the pair of wall base materials 10, 10, and the lower end between the pair of wall base materials 10, 10 is shielded by the baseboards 4, 4. Therefore, in this embodiment 1, the support part 22 (a pair of legs 23, 23) is inserted from the upper end of the baseboard 4 at one end (left end) 3a of the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 to the upper end of the baseboard 4 at the other end (right end) 3b.
なお、支持部22の外面23a,23aには、挿入前に予め接着剤を塗布しておく。支持部22を挿入する際、枠本体部21が一対の壁下地材10,10の切り欠き3,3の周縁に沿うように、枠本体部21を手で変形(湾曲)させながら、支持部22を挿入していく。支持部22は、一対の壁下地材10,10の切り欠き3側の端面が枠本体部21に当接するまで挿入する。 Adhesive is applied to the outer surfaces 23a, 23a of the support portion 22 before insertion. When inserting the support portion 22, the frame body portion 21 is deformed (curved) by hand so that the frame body portion 21 fits along the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 while the support portion 22 is being inserted. The support portion 22 is inserted until the end face on the side of the notches 3 of the pair of wall base materials 10, 10 abuts the frame body portion 21.
そして、支持部22を、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3aの巾木4の上端から他端部3bの巾木4の上端に亘って挿入すると、枠本体部21によって一対の壁下地材10,10間(本実施形態1では巾木4,4の上方)が遮蔽され、一対の壁下地材10,10の開口部2側の端面(本実施形態1では巾木4,4の上方)も遮蔽される。つまり、枠本体部21によって開口部2が縁取られる。この状態で、壁下地材10,10の外側から内側に向かって支持部22が挿入された複数箇所にビス30を打ち込むことにより、支持部22を一対の壁下地材10,10に固定する。 When the support portion 22 is inserted from the upper end of the baseboard 4 at one end 3a of the periphery of the notches 3,3 of the pair of wall base materials 10,10 to the upper end of the baseboard 4 at the other end 3b, the frame body portion 21 shields the space between the pair of wall base materials 10,10 (above the baseboards 4,4 in this embodiment 1), and also shields the end faces of the pair of wall base materials 10,10 on the opening 2 side (above the baseboards 4,4 in this embodiment 1). In other words, the frame body portion 21 borders the opening 2. In this state, the support portion 22 is fixed to the pair of wall base materials 10,10 by driving screws 30 from the outside to the inside of the wall base materials 10,10 at the multiple locations where the support portion 22 has been inserted.
開口枠20の施工後、一対の壁下地材10,10を含む壁Wの化粧面にクロスCを施工する。 After the opening frame 20 is installed, the cloth C is installed on the decorative surface of the wall W, which includes the pair of wall base materials 10, 10.
以上の手順により、開口部構造1が施工され、壁Wに非矩形状(アーチ型)の開口部2が形成される。 By following the above steps, the opening structure 1 is constructed and a non-rectangular (arch-shaped) opening 2 is formed in the wall W.
-実施形態1の効果-
本実施形態1では、非矩形状(アーチ型)の開口部2の開口形状に形成されて該開口部2を縁取る板状の枠本体部21が、ポリ塩化ビニルを主材料とする樹脂材料(第1の軟質材料)で人の手で変形可能に構成されている。そのため、施工現場において枠本体部21を一対の壁下地材10,10の切り欠き3,3の周縁に沿って延びるように変形させながら、一対の壁下地材10,10の切り欠き3,3の周縁に施工することができる。従って、本実施形態1によれば、非矩形状(アーチ型)の開口部2の開口形状に形成されて該開口部2を縁取る板状の枠本体部21を、開口形状に成形しておくことなく、施工現場で変形させながら容易に一対の壁下地材10,10の切り欠き3,3の周縁にぴったりと沿うように精度良く施工することができる。
--Effects of the First Embodiment--
In this embodiment 1, the plate-shaped frame body 21 formed in the opening shape of the non-rectangular (arch-shaped) opening 2 and edging the opening 2 is made of a resin material (first soft material) mainly made of polyvinyl chloride and is deformable by hand. Therefore, the frame body 21 can be deformed at the construction site so as to extend along the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 while being constructed on the periphery of the notches 3, 3 of the pair of wall base materials 10, 10. Therefore, according to this embodiment 1, the plate-shaped frame body 21 formed in the opening shape of the non-rectangular (arch-shaped) opening 2 and edging the opening 2 can be deformed at the construction site so as to easily and precisely fit the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 without being molded into the opening shape.
また、本実施形態1では、支持部22も枠本体部21と同様に長い部材で構成されているが、枠本体部21と同様に、ポリ塩化ビニルを主材料とする樹脂材料(第2の軟質材料)で人の手で変形可能に構成されている。また、支持部22は枠本体部21と一体に構成されている。そのため、施工現場において枠本体部21及び支持部22を一対の壁下地材10,10の切り欠き3,3の周縁に沿って延びるように変形させながら、支持部22を一対の壁下地材10,10間に挿入して支持部22を両壁下地材10,10に固定することにより、容易に開口枠20を施工することができる。従って、本実施形態1によれば、非矩形状(アーチ型)の開口部2の開口形状に形成されて該開口部2を縁取る開口枠20を、施工現場で変形させながら容易に非矩形状(アーチ型)の開口部2の周縁にぴったりと沿うように精度良く施工することができる。 In this embodiment 1, the support part 22 is also made of a long member like the frame body part 21, but like the frame body part 21, it is made of a resin material (second soft material) mainly made of polyvinyl chloride and is made deformable by hand. The support part 22 is also made integral with the frame body part 21. Therefore, the opening frame 20 can be easily constructed by deforming the frame body part 21 and the support part 22 so that they extend along the periphery of the cutouts 3, 3 of the pair of wall base materials 10, 10 at the construction site, inserting the support part 22 between the pair of wall base materials 10, 10 and fixing the support part 22 to both wall base materials 10, 10. Therefore, according to this embodiment 1, the opening frame 20, which is formed in the opening shape of the non-rectangular (arch-shaped) opening 2 and borders the opening 2, can be easily constructed with high precision so as to fit closely to the periphery of the non-rectangular (arch-shaped) opening 2 while being deformed at the construction site.
また、本実施形態1では、支持部22が一対の板状の脚部23,23からなる。このような構成によれば、一対の壁下地材10,10に固定して枠本体部21を支持する支持部22を、必要最小限の分量の材料(第2の軟質材料)で軽量に且つ変形し易く構成することができる。 In addition, in this embodiment 1, the support portion 22 is composed of a pair of plate-shaped legs 23, 23. With this configuration, the support portion 22, which is fixed to a pair of wall base materials 10, 10 and supports the frame main body portion 21, can be constructed to be lightweight and easily deformable using the minimum amount of material (second soft material).
また、本実施形態1では、一対の壁下地材10,10間に挿入されて一対の壁下地材10,10の内面と当接する支持部22の2つの外面23a,23aの少なくとも一部が、凹凸形状に形成されている。そのため、支持部22が一対の壁下地材10,10間に挿入された際に、支持部22の外面23a,23aと壁下地材10,10の内面との摩擦抵抗が増大し、支持部22が一対の壁下地材10,10にひっかかり易くなる。そのため、一対の壁下地材10,10に支持部22を固定する際に、支持部22がずれるのを抑制することができ、固定作業が容易になる。 In addition, in this embodiment 1, at least a portion of the two outer surfaces 23a, 23a of the support portion 22 that is inserted between a pair of wall base materials 10, 10 and abuts against the inner surfaces of the pair of wall base materials 10, 10 is formed in an uneven shape. Therefore, when the support portion 22 is inserted between the pair of wall base materials 10, 10, the frictional resistance between the outer surfaces 23a, 23a of the support portion 22 and the inner surfaces of the wall base materials 10, 10 increases, making it easier for the support portion 22 to get caught on the pair of wall base materials 10, 10. Therefore, when the support portion 22 is fixed to the pair of wall base materials 10, 10, it is possible to prevent the support portion 22 from shifting, making the fixing work easier.
また、本実施形態1によれば、壁Wに非矩形状(アーチ型)の開口部2を形成する開口部構造1が、上述のような開口枠20を備えることにより、壁Wに非矩形状(アーチ型)の開口部2を容易に形成することができる。 In addition, according to this embodiment 1, the opening structure 1 for forming a non-rectangular (arch-shaped) opening 2 in the wall W includes the opening frame 20 as described above, so that the non-rectangular (arch-shaped) opening 2 can be easily formed in the wall W.
《発明の実施形態2》
図5及び図6に示すように、実施形態2の開口部構造1は、開口枠20の枠本体部21と支持部22とを別体に構成したものである。以下では、実施形態1と異なる部分についてのみ詳細に説明し、実施形態1と同様の構成については、詳細な説明を省略する。
Second Embodiment of the Invention
5 and 6, the opening structure 1 of the second embodiment is configured such that the frame body 21 and the support 22 of the opening frame 20 are separately constructed. In the following, only the parts different from the first embodiment will be described in detail, and the detailed description of the same configuration as the first embodiment will be omitted.
〔開口枠〕
実施形態2においても開口枠20は、一対の壁下地材10,10間を遮蔽する板状の枠本体部21と、枠本体部21を支持する支持部22とを備えている。また、本実施形態2では、枠本体部21と支持部22とは、実施形態1と同様にポリ塩化ビニルを主材料とする樹脂材料(第1及び第2の軟質材料)で構成されているが、別体に構成されている。別体に構成された枠本体部21と支持部22とは、いずれも人の手で変形可能に構成されている。
[Opening frame]
In the second embodiment as well, the opening frame 20 includes a plate-shaped frame body 21 that shields the space between a pair of wall base materials 10, 10, and a support portion 22 that supports the frame body 21. In the second embodiment, the frame body 21 and the support portion 22 are made of resin materials (first and second soft materials) mainly made of polyvinyl chloride, as in the first embodiment, but are made separately. The frame body 21 and the support portion 22 that are made separately are both made to be deformable by hand.
実施形態2では、枠本体部21は、幅狭で薄い長尺の矩形状の板状部分24と、支持部22と係合する係合部25とを有している。板状部分24と係合部25とは、ポリ塩化ビニル(第1の軟質材料)で一体に形成されている。 In the second embodiment, the frame body 21 has a narrow, thin, long rectangular plate-shaped portion 24 and an engagement portion 25 that engages with the support portion 22. The plate-shaped portion 24 and the engagement portion 25 are integrally formed from polyvinyl chloride (first soft material).
板状部分24の幅は、実施形態1の枠本体部21の幅と同様に、壁Wの厚みよりも4~10mm程度長く形成されている。そのため、枠本体部21の板状部分24は、壁Wの前面及び後面よりも前後にそれぞれ2~5mm程度(好ましくは3mm以上)突出している。このように枠本体部21の幅を壁Wの厚みよりも長くすることにより、見切材を用いることなくクロスC等の化粧材を止めることができる。また、枠本体部21の突出部にクロスCをぶつけてカットすることで、クロスCの端部が目立ち難くなり、端部処理が容易になる。 The width of the plate-like portion 24 is formed to be approximately 4 to 10 mm longer than the thickness of the wall W, similar to the width of the frame body 21 in embodiment 1. Therefore, the plate-like portion 24 of the frame body 21 protrudes approximately 2 to 5 mm (preferably 3 mm or more) forward and backward from the front and rear faces of the wall W. By making the width of the frame body 21 longer than the thickness of the wall W in this way, decorative materials such as cloth C can be secured without using trim materials. Also, by hitting the cloth C against the protruding portion of the frame body 21 and cutting it, the ends of the cloth C become less noticeable and end processing becomes easier.
板状部分24の厚みは、幅方向の両端部が、例えば、2.5~5mm程度に形成され、それ以外の部分は、幅方向の両端部よりも薄く、例えば、1~2.5mm程度に形成されている。なお、板状部分24の厚みは、人の手で板状部分24を一対の壁下地材10,10の切り欠き3,3の周縁に沿って湾曲させることができる厚みであればよく、板状部分24を構成する材料に応じて変更すればよい。 The thickness of the plate-like portion 24 is, for example, about 2.5 to 5 mm at both ends in the width direction, and the remaining portions are thinner than both ends in the width direction, for example, about 1 to 2.5 mm. The thickness of the plate-like portion 24 may be any thickness that allows the plate-like portion 24 to be bent by hand along the periphery of the cutouts 3, 3 of the pair of wall base materials 10, 10, and may be changed depending on the material that constitutes the plate-like portion 24.
板状部分24の長さは、実施形態1の枠本体部21の長さと同様に、一対の壁下地材10,10の切り欠き3,3の周縁の一端部(左端部)3aの巾木4の上端から他端部(右端部)3bの巾木4の上端に亘る長さに形成されている。 The length of the plate-like portion 24 is the same as the length of the frame body portion 21 in embodiment 1, and is formed to a length that extends from the upper end of the baseboard 4 at one end (left end) 3a of the periphery of the notches 3, 3 of a pair of wall base materials 10, 10 to the upper end of the baseboard 4 at the other end (right end) 3b.
係合部25は、板状部分24の片側の面から突出して板状部分24の長手方向に互いに平行に延びる一対の係合片部26,26によって構成されている。一対の係合片部26,26は、いずれも板状部分24に垂直な垂直部と垂直部及び板状部分24に対して傾斜した傾斜部とを有して断面V字形状に形成され、互いの垂直部が向かい合うように設けられている。一対の係合片部26,26は、該一対の係合片部26,26と板状部分24の幅方向の両端部との間に、後述する支持部22の一対の係合片部29,29がそれぞれ嵌まるように、係合片部26の垂直部と板状部分24の幅方向の端部との間の距離が、係合片部29の幅よりも僅かに長くなるように形成されている。 The engaging portion 25 is composed of a pair of engaging pieces 26, 26 that protrude from one surface of the plate-like portion 24 and extend parallel to each other in the longitudinal direction of the plate-like portion 24. Each of the pair of engaging pieces 26, 26 has a vertical portion perpendicular to the plate-like portion 24 and an inclined portion inclined relative to the vertical portion and the plate-like portion 24, and is formed in a V-shaped cross section, with the vertical portions facing each other. The pair of engaging pieces 26, 26 are formed so that the distance between the vertical portion of the engaging piece 26 and the widthwise end of the plate-like portion 24 is slightly longer than the width of the engaging piece 29, so that a pair of engaging pieces 29, 29 of the support portion 22 described later can be fitted between the pair of engaging pieces 26, 26 and both widthwise ends of the plate-like portion 24.
実施形態2では、支持部22は、断面形状がコ字形状で長尺の支持本体部27と、枠本体部21の係合部25(一対の係合片部26,26)と係合する係合部28とを有している。支持本体部27と係合部28とは、ポリ塩化ビニル(第2の軟質材料)で一体に形成されている。なお、実施形態2では、枠本体部21と支持部22とは、同一のポリ塩化ビニルで構成されているが、支持部22には、枠本体部21で用いるポリ塩化ビニルよりも硬度の高いポリ塩化ビニルが用いられている。 In the second embodiment, the support portion 22 has a long support body portion 27 with a U-shaped cross section, and an engagement portion 28 that engages with the engagement portion 25 (a pair of engagement pieces 26, 26) of the frame body portion 21. The support body portion 27 and the engagement portion 28 are integrally formed from polyvinyl chloride (a second soft material). Note that in the second embodiment, the frame body portion 21 and the support portion 22 are made of the same polyvinyl chloride, but the support portion 22 is made of polyvinyl chloride that is harder than the polyvinyl chloride used in the frame body portion 21.
支持本体部27は、一対の脚部27a,27aと連結部27bとにより、断面がコ字形状に形成されている。一対の脚部27a,27aは、同様に構成されている。一対の脚部27a,27aは、支持部22の支持本体部27が一対の壁下地材10,10間に挿入された際に、外面27c,27cが一対の壁下地材10,10の内面に当接するように、外面27c,27c間の距離が一対の壁下地材10,10の内面間の距離と等しい又は僅かに大きい長さになるように形成されている。 The support body 27 is formed with a U-shaped cross section by a pair of legs 27a, 27a and a connecting portion 27b. The pair of legs 27a, 27a are configured in the same way. The pair of legs 27a, 27a are formed so that when the support body 27 of the support portion 22 is inserted between the pair of wall base materials 10, 10, the distance between the outer surfaces 27c, 27c is equal to or slightly greater than the distance between the inner surfaces of the pair of wall base materials 10, 10 so that the outer surfaces 27c, 27c abut against the inner surfaces of the pair of wall base materials 10, 10.
脚部27aは、幅狭で薄い長尺の矩形状の板状部分である。脚部27aの幅(突出高さ)は、20~40mm程度に形成されている。脚部27aの厚みは、1~2mm程度に形成されている。脚部27aの長さは、枠本体部21の長さ方向の一端から他端に亘る長さ(即ち、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3aの巾木4の上端から他端部3bの巾木4の上端に亘る長さ)に形成されている。 The leg 27a is a long, narrow, thin rectangular plate-like portion. The width (protruding height) of the leg 27a is formed to be approximately 20 to 40 mm. The thickness of the leg 27a is formed to be approximately 1 to 2 mm. The length of the leg 27a is formed to be a length extending from one end to the other end in the longitudinal direction of the frame main body 21 (i.e., a length extending from the upper end of the baseboard 4 at one end 3a of the periphery of the notches 3, 3 of a pair of wall base materials 10, 10 to the upper end of the baseboard 4 at the other end 3b).
連結部27bは、薄い長尺の矩形状の板状部分であり、一対の脚部27a,27aの一端部を連結している。連結部27bの幅は、一対の脚部27a,27aの外面27c,27c間の距離と等しい長さに形成されている。連結部27bの厚みは、脚部27aの厚みと同一であり、1~2mm程度に形成されている。連結部27bの長さは、脚部27aの長さと同じ長さに形成されている。 The connecting portion 27b is a thin, long rectangular plate-like portion that connects one end of the pair of legs 27a, 27a. The width of the connecting portion 27b is formed to a length equal to the distance between the outer surfaces 27c, 27c of the pair of legs 27a, 27a. The thickness of the connecting portion 27b is the same as the thickness of the leg 27a, and is formed to be approximately 1 to 2 mm. The length of the connecting portion 27b is formed to be the same as the length of the leg 27a.
係合部28は、支持本体部27の一対の脚部27a,27aの他端(連結部27bとは逆側の端)にそれぞれ連続して各脚部27aの長手方向に延びる各脚部27aに垂直な一対の平板状の係合片部29,29によって構成されている。各係合片部29は、脚部27aの他端から内側に延びる内側部分29aと、脚部27aの他端から外側に延びる外側部分29bとを有している。 The engagement portion 28 is composed of a pair of flat engagement pieces 29, 29 that are continuous with the other ends (the ends opposite the connecting portion 27b) of the pair of legs 27a, 27a of the support body 27 and extend in the longitudinal direction of each leg 27a and are perpendicular to each leg 27a. Each engagement piece 29 has an inner portion 29a that extends inward from the other end of the leg 27a and an outer portion 29b that extends outward from the other end of the leg 27a.
支持部22は、支持本体部27が一対の壁下地材10,10間に挿入され、支持本体部27の2つの外面27c,27cが一対の壁下地材10,10の内面に当接し、一対の係合片部29,29の外側部分29b,29bが一対の壁下地材10,10の切り欠き3側の端面に当接した状態で、ビス31,31によって一対の壁下地材10,10に固定されている。 The support portion 22 is fixed to the pair of wall base materials 10, 10 by screws 31, 31 with the support body portion 27 inserted between the pair of wall base materials 10, 10, the two outer surfaces 27c, 27c of the support body portion 27 abutting the inner surfaces of the pair of wall base materials 10, 10, and the outer portions 29b, 29b of the pair of engagement pieces 29, 29 abutting the end faces on the cutout 3 side of the pair of wall base materials 10, 10.
また、一対の壁下地材10,10に固定された支持部22の一対の係合片部29,29が、枠本体部21の一対の係合片部26,26と板状部分24の幅方向の両端部との間にそれぞれ嵌まるように、枠本体部21を支持部22に押し付けると、枠本体部21の一対の係合片部26,26が、支持部22の一対の係合片部29,29の内側部分29a,29aにひっかかる(係合する)ことにより、枠本体部21が支持部22に取り付けられる。つまり、枠本体部21の係合部25と支持部22の係合部28とは、互いに係合させると、枠本体部21が支持部22に取り付けられて支持されるように構成されている。 When the frame body 21 is pressed against the support 22 so that the pair of engagement pieces 29, 29 of the support 22 fixed to the pair of wall underlayment materials 10, 10 fit between the pair of engagement pieces 26, 26 of the frame body 21 and both ends of the plate-like portion 24 in the width direction, the pair of engagement pieces 26, 26 of the frame body 21 hook (engage) with the inner portions 29a, 29a of the pair of engagement pieces 29, 29 of the support 22, thereby attaching the frame body 21 to the support 22. In other words, when the engagement parts 25 of the frame body 21 and the engagement parts 28 of the support 22 are engaged with each other, the frame body 21 is attached to the support 22 and supported.
-開口部構造の施工方法-
次に、開口部構造1の施工方法について説明する。実施形態2においても、まず、一対の壁下地材10,10を施工し、その下端部に巾木4,4を施工する。一対の壁下地材10,10及び巾木4,4の施工方法は、実施形態1と同様であるため説明を省略する。
- Opening structure construction method -
Next, a description will be given of a construction method for the opening structure 1. In the second embodiment as well, first, a pair of wall base materials 10, 10 are constructed, and then baseboards 4, 4 are constructed at their lower ends. The construction method for the pair of wall base materials 10, 10 and the baseboards 4, 4 is the same as in the first embodiment, and therefore the description will be omitted.
次に、開口枠20を施工する。実施形態2では、枠本体部21と別体に構成された支持部22を先に一対の壁下地材10,10に固定する。 Next, the opening frame 20 is constructed. In the second embodiment, the support part 22, which is constructed separately from the frame main body part 21, is first fixed to a pair of wall base materials 10, 10.
具体的には、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3a側から他端部3b側へ(逆も可)、順に支持部22の支持本体部27を一対の壁下地材10,10間に挿入していく。支持部22の2つの外面27c,27cには、挿入前に予め接着剤を塗布しておく。支持部22の支持本体部27を挿入する際、支持部22が一対の壁下地材10,10の切り欠き3,3の周縁に沿うように、支持部22を手で変形(湾曲)させながら挿入していく。支持部22は、係合部28の一対の平板状の係合片部29,29の外側部分29b,29bが一対の壁下地材10,10の切り欠き3側の端面に当接するまで挿入する。 Specifically, the support body 27 of the support part 22 is inserted between the pair of wall base materials 10, 10 in order from one end 3a side to the other end 3b side of the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 (or vice versa). Adhesive is applied to the two outer surfaces 27c, 27c of the support part 22 before insertion. When inserting the support body 27 of the support part 22, the support part 22 is inserted while being deformed (curved) by hand so that the support part 22 fits along the periphery of the notches 3, 3 of the pair of wall base materials 10, 10. The support part 22 is inserted until the outer parts 29b, 29b of the pair of flat engagement pieces 29, 29 of the engagement part 28 abut the end faces on the notches 3 side of the pair of wall base materials 10, 10.
そして、支持部22の支持本体部27を、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3aの巾木4の上端から他端部3bの巾木4の上端に亘って挿入した状態で、壁下地材10,10の外側から内側に向かって支持部22の支持本体部27が挿入された複数箇所にビス31を打ち込むことにより、支持部22を一対の壁下地材10,10に固定する。 Then, with the support body 27 of the support part 22 inserted from the top end of the baseboard 4 at one end 3a of the periphery of the notches 3,3 of the pair of wall base materials 10,10 to the top end of the baseboard 4 at the other end 3b, screws 31 are driven from the outside to the inside of the wall base materials 10,10 into the multiple locations where the support body 27 of the support part 22 has been inserted, thereby fixing the support part 22 to the pair of wall base materials 10,10.
支持部22の固定後、枠本体部21を支持部22に取り付ける。具体的には、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3a側から他端部3b側へ(逆も可)、順に枠本体部21を支持部22に押し付けていく。枠本体部21が押し付けられた部分では、枠本体部21の一対の係合片部26,26の傾斜部が、支持部22の一対の係合片部29,29の内側部分29a,29aを乗り越え、該内側部分29a,29aにひっかかる。また、支持部22の一対の係合片部29,29が、枠本体部21の一対の係合片部26,26と板状部分24の幅方向の両端部との間にそれぞれ嵌まる。このように、枠本体部21の一対の係合片部26,26が、支持部22の一対の係合片部29,29の内側部分29a,29aにひっかかる(枠本体部21及び支持部22の係合部25,28が互いに係合する)ことにより、枠本体部21が支持部22に取り付けられる。 After the support portion 22 is fixed, the frame body portion 21 is attached to the support portion 22. Specifically, the frame body portion 21 is pressed against the support portion 22 in sequence from one end 3a side to the other end 3b side of the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 (or vice versa). In the portion where the frame body portion 21 is pressed, the inclined portions of the pair of engagement pieces 26, 26 of the frame body portion 21 climb over the inner portions 29a, 29a of the pair of engagement pieces 29, 29 of the support portion 22 and get caught on the inner portions 29a, 29a. In addition, the pair of engagement pieces 29, 29 of the support portion 22 fit between the pair of engagement pieces 26, 26 of the frame body portion 21 and both ends of the plate-shaped portion 24 in the width direction, respectively. In this way, the pair of engagement pieces 26, 26 of the frame body 21 hook onto the inner portions 29a, 29a of the pair of engagement pieces 29, 29 of the support part 22 (the engagement parts 25, 28 of the frame body 21 and the support part 22 engage with each other), and the frame body 21 is attached to the support part 22.
このようにして、一対の壁下地材10,10の切り欠き3,3の周縁の一端部3aの巾木4の上端から他端部3bの巾木4の上端に亘って枠本体部21を支持部22に取り付けると、枠本体部21によって一対の壁下地材10,10間(巾木4,4の上方)が遮蔽され、一対の壁下地材10,10の開口部2側の端面(巾木4,4の上方)も遮蔽される。つまり、枠本体部21によって開口部2が縁取られる。 In this way, when the frame body 21 is attached to the support 22 from the upper end of the baseboard 4 at one end 3a of the periphery of the notches 3,3 of a pair of wall base materials 10,10 to the upper end of the baseboard 4 at the other end 3b, the frame body 21 shields the space between the pair of wall base materials 10,10 (above the baseboards 4,4) and also shields the end faces of the pair of wall base materials 10,10 on the opening 2 side (above the baseboards 4,4). In other words, the frame body 21 borders the opening 2.
開口枠20の施工後、一対の壁下地材10,10を含む壁Wの化粧面にクロスCを施工する。 After the opening frame 20 is installed, the cloth C is installed on the decorative surface of the wall W, which includes the pair of wall base materials 10, 10.
以上の手順により、開口部構造1が施工され、壁Wに非矩形状(アーチ型)の開口部2が形成される。 By following the above steps, the opening structure 1 is constructed and a non-rectangular (arch-shaped) opening 2 is formed in the wall W.
-実施形態2の効果-
本実施形態2においても、非矩形状(アーチ型)の開口部2の開口形状に形成されて該開口部2を縁取る板状の枠本体部21が、ポリ塩化ビニルを主材料とする樹脂材料(第1の軟質材料)で人の手で変形可能に構成されている。そのため、施工現場において枠本体部21を一対の壁下地材10,10の切り欠き3,3の周縁に沿って延びるように変形させながら、一対の壁下地材10,10の切り欠き3,3の周縁に施工することができる。従って、本実施形態1によれば、非矩形状(アーチ型)の開口部2の開口形状に形成されて該開口部2を縁取る板状の枠本体部21を、開口形状に成形しておくことなく、施工現場で変形させながら容易に一対の壁下地材10,10の切り欠き3,3の周縁にぴったりと沿うように精度良く施工することができる。
--Effects of the second embodiment--
In the second embodiment, the plate-shaped frame body 21 formed in the opening shape of the non-rectangular (arch-shaped) opening 2 and edging the opening 2 is made of a resin material (first soft material) mainly made of polyvinyl chloride and is deformable by hand. Therefore, the frame body 21 can be deformed at the construction site to extend along the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 while being constructed on the periphery of the notches 3, 3 of the pair of wall base materials 10, 10. Therefore, according to the first embodiment, the plate-shaped frame body 21 formed in the opening shape of the non-rectangular (arch-shaped) opening 2 and edging the opening 2 can be deformed at the construction site to easily and precisely fit the periphery of the notches 3, 3 of the pair of wall base materials 10, 10 without being molded into the opening shape.
また、本実施形態2では、支持部22が枠本体部21とは別体に構成され、係合部25,28どうしを係合させるだけで、支持部22に容易に枠本体部21を取り付けることができるように構成されている。このような構成によれば、支持部22を先に一対の壁下地材10,10に挿入して固定し、固定された支持部22に枠本体部21を取り付けることにより、開口枠20を容易に施工することができる。 In addition, in this embodiment 2, the support portion 22 is configured separately from the frame body portion 21, and is configured so that the frame body portion 21 can be easily attached to the support portion 22 simply by engaging the engagement portions 25, 28. With this configuration, the support portion 22 is first inserted into and fixed in a pair of wall base materials 10, 10, and the frame body portion 21 is then attached to the fixed support portion 22, allowing the opening frame 20 to be easily constructed.
また、本実施形態2では、支持部22も枠本体部21と同様に長い部材で構成されているが、枠本体部21と同様に、ポリ塩化ビニルを主材料とする樹脂材料(第2の軟質材料)で人の手で変形可能に構成されている。そのため、施工現場において支持部22を容易に変形させることができるため、支持部22を変形させながら一対の壁下地材10,10間に挿入することにより、容易に一対の壁下地材10,10の切り欠き3,3の外周に沿うように配置することができる。従って、本実施形態2によれば、施工現場において、非矩形状の開口部2を縁取る開口枠20を、容易に、非矩形状(アーチ型)の開口部2の周縁にぴったりと沿うように精度良く施工することができる。 In the second embodiment, the support portion 22 is also made of a long member like the frame body portion 21, but like the frame body portion 21, it is made of a resin material (second soft material) mainly made of polyvinyl chloride and is deformable by hand. Therefore, the support portion 22 can be easily deformed at the construction site, and by inserting the support portion 22 between a pair of wall base materials 10, 10 while deforming it, it can be easily positioned so as to follow the outer periphery of the cutouts 3, 3 of the pair of wall base materials 10, 10. Therefore, according to the second embodiment, the opening frame 20 that borders the non-rectangular opening 2 can be easily and precisely constructed at the construction site so as to fit closely to the periphery of the non-rectangular (arch-shaped) opening 2.
また、本実施形態1によっても、壁Wに非矩形状(アーチ型)の開口部2を形成する開口部構造1が、上述のような開口枠20を備えることにより、壁Wに非矩形状(アーチ型)の開口部2を容易に形成することができる。 Also, in this embodiment 1, the opening structure 1 for forming a non-rectangular (arch-shaped) opening 2 in the wall W includes the opening frame 20 as described above, so that the non-rectangular (arch-shaped) opening 2 can be easily formed in the wall W.
《その他の実施形態》
上記実施形態1,2では、非矩形状の開口部2の一例としてアーチ型の開口部2を形成する例について説明したが、本発明に係る開口枠20が適用される非矩形状の開口部2は、アーチ型に限られない。特に、本発明に係る開口枠20は、円形状や半円形状の開口部2等、湾曲部を有する開口部2に適用されると、壁Wに非矩形状の開口部2を容易に形成することができるという本発明が奏する効果がより顕著になる。
Other Embodiments
In the above-mentioned first and second embodiments, an example of forming an arch-shaped opening 2 has been described as an example of a non-rectangular opening 2, but the non-rectangular opening 2 to which the opening frame 20 according to the present invention is applied is not limited to an arch-shaped opening. In particular, when the opening frame 20 according to the present invention is applied to an opening 2 having a curved portion, such as a circular or semicircular opening 2, the effect of the present invention that a non-rectangular opening 2 can be easily formed in the wall W becomes more remarkable.
上記実施形態1,2では、壁下地材10は、3つの石膏ボード11~13で構成されていたが、壁下地材10の構成はこれに限られない。壁下地材10は、1つ,2つ又は4つ以上の石膏ボードで構成されていてもよく、1つ又は複数の木質ボードで構成されていてもよい。 In the above first and second embodiments, the wall base material 10 is composed of three gypsum boards 11 to 13, but the configuration of the wall base material 10 is not limited to this. The wall base material 10 may be composed of one, two, four or more gypsum boards, or one or more wood boards.
また、上記実施形態1,2では、開口枠20は、一連の部材で構成されていたが、開口枠20を複数の部材で構成してもよい。 In addition, in the above embodiments 1 and 2, the opening frame 20 is composed of a single member, but the opening frame 20 may be composed of multiple members.
また、上記実施形態1,2では、枠本体部21を構成する第1の軟質材料として、ポリ塩化ビニルを主材料とする樹脂材料を用いていたが、枠本体部21を構成する第1の軟質材料は、枠本体部21を人の手で変形可能に構成することができる材料であればいかなるものであってもよい。第1の軟質材料として、ポリ塩化ビニルの他、例えば、合成樹脂材料や天然樹脂材料等の弾性を有する材料を用いることができる。 In addition, in the above-mentioned first and second embodiments, a resin material mainly made of polyvinyl chloride is used as the first soft material constituting the frame body 21, but the first soft material constituting the frame body 21 may be any material that can be used to make the frame body 21 deformable by hand. In addition to polyvinyl chloride, materials having elasticity, such as synthetic resin materials and natural resin materials, can be used as the first soft material.
また、上記実施形態1,2では、支持部22を構成する第2の軟質材料として、ポリ塩化ビニルを主材料とする樹脂材料を用いていたが、支持部22を構成する第2の軟質材料は、支持部22を人の手で変形可能に構成することができる材料であればいかなるものであってもよい。第2の軟質材料として、ポリ塩化ビニルの他、例えば、合成樹脂材料や天然樹脂材料等の弾性を有する材料を用いることができる。 In addition, in the above-mentioned first and second embodiments, a resin material mainly made of polyvinyl chloride is used as the second soft material constituting the support part 22, but the second soft material constituting the support part 22 may be any material that can make the support part 22 deformable by human hands. In addition to polyvinyl chloride, materials having elasticity such as synthetic resin materials and natural resin materials can be used as the second soft material.
また、上記実施形態1,2では、枠本体部21を構成する第1の軟質材料と支持部22を構成する第2の軟質材料とが同一の材料(塩化ビニルを主材料とする樹脂材料)である場合について説明したが、枠本体部21を構成する第1の軟質材料と支持部22を構成する第2の軟質材料とは異なる材料であってもよい。 In addition, in the above-mentioned first and second embodiments, the first soft material constituting the frame main body 21 and the second soft material constituting the support part 22 are described as being the same material (a resin material mainly made of polyvinyl chloride), but the first soft material constituting the frame main body 21 and the second soft material constituting the support part 22 may be different materials.
また、上記実施形態1,2では、枠本体部21は、幅が壁Wの厚みよりも4~10mm程度長くなるように形成され、壁Wの前面及び後面よりも前後にそれぞれ2~5mm程度突出するように形成されていたが、枠本体部21は、上記の構成に限られない。枠本体部21は、幅が壁Wの厚みと同一の長さになるように形成されていてもよく、また、壁Wの前面及び後面において折れ曲がり、壁Wの前面及び後面に沿って延びる見切部を有するものであってもよい。 In addition, in the above-mentioned first and second embodiments, the frame body 21 is formed so that its width is approximately 4 to 10 mm longer than the thickness of the wall W, and is formed so that it protrudes approximately 2 to 5 mm forward and backward from the front and rear surfaces of the wall W, respectively, but the frame body 21 is not limited to the above configuration. The frame body 21 may be formed so that its width is the same length as the thickness of the wall W, and may also be bent at the front and rear surfaces of the wall W and have edge portions that extend along the front and rear surfaces of the wall W.
また、上記実施形態1,2では、支持部22は、一対の脚部23,23/27a,27aを有するように構成されていたが、このような構成に限られない。支持部22は、一対の壁下地材10,10の内面に固定できるように、一対の壁下地材10,10間に挿入されて該一対の壁下地材10,10の内面に当接する2つの外面23a,23a/27c,27cを有するように構成されていればよい。例えば、実施形態1において、支持部22は、一対の脚部23,23に架け渡された桟状片部を有するものであってもよく、枠本体部21の片側の面から、一対の脚部23,23の代わりに断面が矩形状の柱状体が突出するものであってもよい。また、実施形態2においても同様に、支持部22は、一対の脚部27a,27aに架け渡された桟状片部を有するものであってもよく、支持本体部27を断面矩形状の柱状体で構成し、枠本体部21の一対の係合片部26,26が収まる溝等を形成してもよい。 In addition, in the above-mentioned embodiments 1 and 2, the support portion 22 is configured to have a pair of legs 23, 23/27a, 27a, but is not limited to such a configuration. The support portion 22 may be inserted between a pair of wall base materials 10, 10 and configured to have two outer surfaces 23a, 23a/27c, 27c that abut against the inner surfaces of the pair of wall base materials 10, 10 so that it can be fixed to the inner surfaces of the pair of wall base materials 10, 10. For example, in embodiment 1, the support portion 22 may have a bar-shaped piece portion that is bridged across the pair of legs 23, 23, or a columnar body with a rectangular cross section may protrude from one side of the frame main body portion 21 instead of the pair of legs 23, 23. Similarly, in the second embodiment, the support portion 22 may have a bar-shaped piece portion that is spanned between a pair of legs 27a, 27a, and the support body portion 27 may be configured as a columnar body with a rectangular cross section, and may have a groove or the like formed therein into which the pair of engagement pieces 26, 26 of the frame body portion 21 are fitted.
また、上記実施形態1では、枠本体部21と支持部22とが、射出成形によって一体に構成されていたが、枠本体部21と支持部22とを一体に構成する手法は射出成形に限られない。枠本体部21と支持部22とは、個別に成形した後、接着・融着・溶着等によって固着させて一体化させてもよい。 In addition, in the above-mentioned first embodiment, the frame body 21 and the support portion 22 are integrally formed by injection molding, but the method of integrally forming the frame body 21 and the support portion 22 is not limited to injection molding. The frame body 21 and the support portion 22 may be molded separately and then fixed together by adhesion, fusion, welding, or the like to be integrated.
また、上記実施形態2では、支持部22の2つの外面27c,27cは平坦面に構成されていたが、実施形態1の支持部22の2つの外面23a,23aと同様に、少なくとも一部が、凹凸形状に形成されていてもよい。このような構成によれば、支持部22の支持本体部27が一対の壁下地材10,10間に挿入された際に、支持部22の外面27c,27cと壁下地材10,10の内面との摩擦抵抗が増大し、支持部22が一対の壁下地材10,10にひっかかり易くなる。そのため、一対の壁下地材10,10に支持部22を固定する際に、支持部22がずれるのを抑制することができ、固定作業が容易になる。 In the above-mentioned second embodiment, the two outer surfaces 27c, 27c of the support portion 22 are configured as flat surfaces, but at least a part of them may be formed in an uneven shape, similar to the two outer surfaces 23a, 23a of the support portion 22 in the first embodiment. With this configuration, when the support body portion 27 of the support portion 22 is inserted between the pair of wall base materials 10, 10, the friction resistance between the outer surfaces 27c, 27c of the support portion 22 and the inner surfaces of the wall base materials 10, 10 increases, and the support portion 22 becomes more likely to be caught by the pair of wall base materials 10, 10. Therefore, when the support portion 22 is fixed to the pair of wall base materials 10, 10, the support portion 22 can be prevented from shifting, making the fixing work easier.
なお、上記実施形態1においても、上記実施形態2の変形例においても、支持部22の外面23a,23a/27c,27cの一部だけでなく、全部を凹凸形状に形成してもよい。また、凹凸形状の形成手法は、複数本の線条突起23b,…,23bを形成することに限られない。支持部22の外面23a,23a/27c,27cに、複数本の線条溝を形成することによって凹凸形状に形成してもよく、複数の凸部や凹部を形成することによって凹凸形状に形成してもよい。 In addition, in both the above-mentioned embodiment 1 and the modified example of the above-mentioned embodiment 2, not only a part of the outer surface 23a, 23a/27c, 27c of the support part 22, but also the entire surface may be formed with an uneven shape. Furthermore, the method of forming the uneven shape is not limited to forming a plurality of linear protrusions 23b, ..., 23b. The uneven shape may be formed by forming a plurality of linear grooves on the outer surface 23a, 23a/27c, 27c of the support part 22, or the uneven shape may be formed by forming a plurality of convex portions or concave portions.
また、上記実施形態1,2では、一対の壁下地材10,10の化粧面(前側の壁下地材10の前面、後側の壁下地材10の後面)に、表面材としてクロスCを施工していたが、一対の壁下地材10,10の化粧面に施工する表面材はクロスCに限られない。例えば、厚さが3mm程度の不燃化粧材(例えば、大建工業(株)製グラビオLS等)を表面材として使用することができる。この場合、一対の壁下地材10,10の表面が不燃材料で覆われるため、キッチン等、火元が近くにある箇所にも使用することができる。つまり、表面材を不燃化粧板とすれば、室内の場所を問わず使用することができる。 In addition, in the above-mentioned first and second embodiments, the cloth C was applied as a surface material to the decorative surfaces of the pair of wall base materials 10, 10 (the front surface of the front wall base material 10 and the rear surface of the rear wall base material 10), but the surface material applied to the decorative surfaces of the pair of wall base materials 10, 10 is not limited to the cloth C. For example, a non-combustible decorative material with a thickness of about 3 mm (e.g., Gravio LS manufactured by Daiken Kogyo Co., Ltd.) can be used as the surface material. In this case, since the surfaces of the pair of wall base materials 10, 10 are covered with a non-combustible material, they can be used in places near a fire source, such as kitchens. In other words, if the surface material is a non-combustible decorative board, they can be used anywhere in the room.
また、表面材を不燃化粧板とする場合にも、上記実施形態1,2の表面材をクロスCとする場合と同様に、開口枠20の枠本体部21が、壁Wの前面及び後面よりも前後にそれぞれ2~5mm程度(好ましくは3mm以上)突出するように、枠本体部21の幅を壁Wの厚みよりも4~10mm程度長く形成することとすれば、見切材を用いることなく不燃化粧板等の化粧材を止めることができる。そして、枠本体部21の突出部に不燃化粧材合わせてカットすることで、不燃化粧材の端部が目立ち難くなり、端部処理が容易になる。 Also, when the surface material is a non-combustible decorative panel, as in the case of using cloth C as the surface material in the above-mentioned embodiments 1 and 2, the width of the frame body 21 of the opening frame 20 can be formed to be about 4 to 10 mm longer than the thickness of the wall W so that the frame body 21 protrudes about 2 to 5 mm (preferably 3 mm or more) forward and backward from the front and rear faces of the wall W, and decorative materials such as non-combustible decorative panels can be secured without using trim materials. Then, by cutting the non-combustible decorative material to fit the protruding parts of the frame body 21, the ends of the non-combustible decorative material become less noticeable, making end processing easier.
