Description

本願発明は、木造住宅に代表される建築物の屋内側に設置される内壁に関するものであり、より具体的には、床や構造壁や柱など（以下、これらを総称して「構造体」という。）に、内壁板などの面板を取り付けるための取付部材、及びこの取付部材を利用した内装構造に関するものである。 The present invention relates to an inner wall installed on the indoor side of a building represented by a wooden house. More specifically, the present invention relates to a floor, a structural wall, a pillar, etc. (hereinafter collectively referred to as “structure”). .) To an attachment member for attaching a face plate such as an inner wall plate, and an interior structure using the attachment member.

直上階からの騒音は、かねてから建築物における大きな問題のひとつであった。建築物の場合、空気伝搬音を除き、下階で受ける騒音はそのほとんどが固体音によるものであるといっても過言ではない。この固体音を軽減する（つまり減衰させる）ことが従来から課題となっていた。 Noise from the upper floor has long been one of the major problems in buildings. In the case of buildings, it is no exaggeration to say that most of the noise received on the lower floor is due to solid sound, except for airborne sound. Conventionally, it has been a problem to reduce (that is, attenuate) the solid sound.

固体音とは、固体に衝撃を与えたときに固体が振動し、その振動の結果この固体の中を伝搬する波によって生ずる音のことである。この固体音が室内に放出され、空気を振動させることで、騒音として人に伝わる。例えば、上階で人が飛び跳ねると、これが床に対する衝撃となって床の中を固体音が伝搬し、この固体音が階下に放出されることで騒音が生ずる。 A solid sound is a sound generated by a wave that propagates through a solid as a result of the vibration of the solid when an impact is applied to the solid. This solid sound is emitted into the room and is transmitted to people as noise by vibrating the air. For example, when a person jumps up and down on the upper floor, this acts as an impact on the floor, and solid sound propagates through the floor, and noise is generated by releasing this solid sound to the lower floor.

また固体音は、衝撃を与えた固体（例えば構造体）から直接放出されて騒音となる一次固体音と、衝撃を与え構造体からさらに他の構造体を伝搬した後に放出されて騒音となる二次固体音に、大別される。固体音のうち二次固体音は、連続するあらゆる構造体の中を伝搬するためその伝搬経路が複雑であり、しかも低周波成分が卓越して波長が大きいことから、これを減衰させることは極めて困難であった。 In addition, solid sound is emitted directly from an impacted solid (for example, a structure) and becomes noise, and solid sound is emitted after propagating from the structure to another structure and becomes noise. It is roughly divided into the following solid sounds. Of the solid sounds, the secondary solid sound propagates through all the continuous structures, so its propagation path is complicated, and the low frequency component is dominant and the wavelength is large. It was difficult.

騒音を低減する課題を解決すべくこれまでも種々の提案がなされており、たとえば以下に示す特許文献１も、建物の上階から下階へ伝わる騒音を問題としてこれを解決する対策技術を提案している。 Various proposals have been made so far in order to solve the problem of reducing noise. For example, Patent Document 1 shown below proposes a countermeasure technique for solving this problem with noise transmitted from the upper floor to the lower floor of the building as a problem. doing.

特開２０１０−２６５６１９号公報JP 2010-265619 A

特許文献１は、床材を支える床梁にダンパーを取り付けるとともに、床梁と床梁の間に吸音材を設ける床構造を提案するものである。このダンパーは上下に分かれた２つのダンパー部材からなり、これら２つのダンパー材の固有振動数を同一とすることで床振動の抑制を図っている。 Patent Document 1 proposes a floor structure in which a damper is attached to a floor beam that supports the floor material, and a sound absorbing material is provided between the floor beam and the floor beam. This damper is composed of two damper members divided into upper and lower parts, and floor vibrations are suppressed by making the natural frequencies of these two damper materials the same.

しかしながら、特許文献１では、分割構造のダンパーを設置する必要があり、その製造や設置に煩雑な手間がかかり、つまり施工にかかる期間やコストが増加するという採用し難い一面がある。さらに、一般的な構造である、野縁と野縁受と吊木の組み合わせで天井板を設置する場合、上階床と天井板との間隔が広くなるため、必ずしもダンパーによる減衰効果と特定しがたい。 However, in Patent Document 1, it is necessary to install a damper having a divided structure, and it takes a troublesome manufacturing and installation, that is, there is an aspect that is difficult to adopt, that is, a period and cost for construction increase. Furthermore, when installing a ceiling board with a combination of a field edge, a field edge receiver, and a suspended tree, which is a general structure, the distance between the upper floor and the ceiling board is widened. It ’s hard.

本願発明の課題は、従来技術が抱える問題を解消することである。すなわち、構造体（例えば上階の床）に面板（例えば天井板）を取り付けるために必要な部材以外のものは必要とせず、しかも固体音（とくに二次固体音）を減衰させることのできる、取付部材、及びこの取付部材を利用した内装構造を提供することにある。 The subject of this invention is solving the problem which a prior art has. That is, it is possible to attenuate solid sound (especially secondary solid sound) without the need for members other than those necessary for attaching a face plate (for example, a ceiling plate) to a structure (for example, an upper floor). It is in providing an attachment member and the interior structure using this attachment member.

本願発明は、構造体（例えば上階の床）に面板（例えば天井板）を取り付けるために必要な取付部材に着目してなされたものであり、取付部材の本来の機能である構造体と面板との取付機能のほか、その弾性変形によって固体音を減衰させる騒音低減機能も、兼ね備えたものを提供すべく開発されたものである。 The present invention has been made by paying attention to an attachment member necessary for attaching a face plate (for example, a ceiling plate) to a structure (for example, an upper floor), and the structure and the face plate which are the original functions of the attachment member. In addition to the mounting function, a noise reduction function for attenuating solid sound by its elastic deformation has been developed to provide a combination.

本願発明の面板取付部材は、構造体（建築物の一部を構成する）と面板（多くは構造体の屋内側に設置される）との間に設けられるものであって、面板を構造体に取り付けるために用いられる取付部材である。さらに、面板を設置する設置面、構造体に固定する係止面、設置面と係止面との間に形成される屈曲部を備えており、設置面は幅方向よりも軸方向の方が長い帯状であり、屈曲部は設置面の幅方向両端側に設けられるとともに屈曲方向が反転する第１折返し部と第２折返し部を有し、設置面を上面としたときに屈曲部は設置面から垂下するように第１折返し部〜第２折返し部の順で形成され、かつ第１折返し部は幅方向内側に折り返されて第２折返し部は幅方向外側に折り返されており、係止面は第２折返し部の外側端部に連続して設けられるとともに本体面と略平行であり、主として固体音の振動による屈曲部の弾性変形で構造物からの音を吸収低減させ得るものである。 The face plate mounting member of the present invention is provided between a structure (which constitutes a part of a building) and a face plate (mostly installed on the indoor side of the structure). It is the attachment member used in order to attach to. Furthermore, it is provided with an installation surface for installing the face plate, a locking surface for fixing to the structure, and a bent portion formed between the installation surface and the locking surface, and the installation surface is more in the axial direction than in the width direction. It has a long band shape, and the bent portion is provided on both ends of the installation surface in the width direction and has a first folded portion and a second folded portion where the bending direction is reversed. Formed in the order of the first folded portion to the second folded portion so as to hang down from the first folded portion, the first folded portion is folded inward in the width direction, and the second folded portion is folded outward in the width direction. Is continuously provided at the outer end portion of the second folded portion and is substantially parallel to the main body surface, and can absorb and reduce sound from the structure mainly by elastic deformation of the bent portion due to vibration of solid sound.

本願発明の面板取付部材は、反曲点（第１折返し部と第２折返し部とが接続する点）から設置面までの「第１間隔」とし、反曲点から係止面までの「第２間隔」とすると、「第１間隔」と「第２間隔」のうちどちらか一方を他方よりも短くすることで、第１折返し部内又は第２折返し部内に狭隘隙間部を形成したものとすることもできる。この場合、狭隘隙間部内に弾性体からなる緩衝部材を挟持させることもできる。 The face plate mounting member of the present invention has a “first interval” from the inflection point (the point at which the first folded portion and the second folded portion are connected) to the installation surface. Assuming that “2 intervals”, one of the “first interval” and the “second interval” is shorter than the other, thereby forming a narrow gap portion in the first folded portion or the second folded portion. You can also. In this case, a buffer member made of an elastic body can be held in the narrow gap portion.

本願発明の面板取付部材は、反曲点（第１折返し部と第２折返し部とが接続する点）付近に、軸方向に延びる細長孔を延設したものとすることもできる。 The face plate attaching member of the present invention may be provided with an elongated hole extending in the axial direction in the vicinity of an inflection point (a point where the first folded portion and the second folded portion are connected).

本願発明の内装構造は、面板取付部材とで構成される内装構造である。面板取付部材は、請求項１乃至請求項４のいずれかに記載される面板取付部材であって、係止面で構造体に固定されるとともに設置面に面板を設置するものである。そして本願発明の内装構造は、複数の面板取付部材が略平行に構造体に固定され、これら面板取付部材には面板が設置された構造であり、面板取付部材の屈曲部の弾性変形によって構造物からの固体音を低減させ得る構造である。 The interior structure of the present invention is an interior structure composed of a face plate mounting member. The face plate attachment member is a face plate attachment member according to any one of claims 1 to 4, and is fixed to the structure body with a locking surface and is provided with a face plate on the installation surface. The interior structure of the present invention is a structure in which a plurality of face plate mounting members are fixed to the structure substantially in parallel, and face plates are installed on these face plate mounting members, and the structure is formed by elastic deformation of the bent portion of the face plate mounting member. It is the structure which can reduce the solid sound from.

本願発明の面板取付部材と内装構造には、次のような効果がある。
（１）面板取付部材を構成する屈曲部が、曲げ方向が反転する第１折返し部と第２折返し部を有しているので容易に弾性変形し得る。その結果、固体音を減衰させることができ、放射騒音の音圧レベルを低下させることができるので、室内の騒音レベルを減少させるとともに、残響時間を短縮させる。
（２）構造体に面板を取り付けるために必要な部材である面板取付部材以外、他の部材を必要としないので、製造や設置の手間が軽減され、その結果、工期が短縮されるとともにコストも軽減される。
（３）反曲点（第１折返し部と第２折返し部とが接続する点）から設置面までの第１間隔を、反曲点から係止面までの第２間隔よりも小さくして、第１折返し部内に狭隘隙間部を形成する面板取付部材とすれば、構造体と面板との間隔が小さい場合であっても容易に設置することができるうえ、面板を強固に取付部材に固定することが可能である。
（４）第１折返し部（あるいは第１折返し部）内に形成される狭隘隙間部に、弾性体からなる緩衝部材を挟持させれば、さらに固体音を減衰させることができ、放射騒音の音圧レベルをより低下させることができる。
（５）反曲点付近に軸方向に延びる細長孔が延設された面板取付部材とすれば、さらに容易に弾性変形し得るので、より固体音を減衰させることができ、放射騒音の音圧レベルを低下させることが可能となる。 The face plate mounting member and the interior structure of the present invention have the following effects.
(1) Since the bending part which comprises a faceplate attachment member has the 1st folding | turning part and 2nd folding | turning part which a bending direction reverses, it can be elastically deformed easily. As a result, the solid sound can be attenuated and the sound pressure level of the radiated noise can be reduced, so that the indoor noise level is reduced and the reverberation time is shortened.
(2) Since no other members are required other than the face plate attachment member, which is a member necessary for attaching the face plate to the structure, the labor of manufacturing and installation is reduced, resulting in a shortened construction period and cost. It is reduced.
(3) The first interval from the inflection point (the point at which the first folding portion and the second folding portion are connected) to the installation surface is made smaller than the second interval from the inflection point to the locking surface, If it is a face plate mounting member that forms a narrow gap in the first folded portion, it can be easily installed even when the distance between the structure and the face plate is small, and the face plate is firmly fixed to the mounting member. It is possible.
(4) If a buffer member made of an elastic body is held in a narrow gap formed in the first folded portion (or the first folded portion), the solid sound can be further attenuated, and the sound of radiated noise The pressure level can be further reduced.
(5) If the face plate mounting member is provided with an elongated hole extending in the axial direction near the inflection point, it can be more easily elastically deformed, so that the solid sound can be further attenuated, and the sound pressure of the radiated noise The level can be lowered.

本願発明の面板取付部材と内装構造の一実施形態を図に基づいて説明する。 [Embodiment]
An embodiment of a face plate mounting member and an interior structure of the present invention will be described with reference to the drawings.

（全体構成）
図１は、本願発明の面板取付部材１が天井面２ａに設置された状態を下方から見上げた斜視図である。ここでいう面板とは、建築物を構成する床や構造壁や柱といった構造体の屋内側に取り付けられる壁板や床板のことであり、また面板取付材１は、天井面２ａに面板を取り付けるためのものである。この図に示すように、面板取付材１は天井面２ａに固定され、面板は面板取付材１に設置され（便宜上この図では面板を省略している）、いわば面板は面板取付材１を介して天井面２ａに取り付けられる。なお本願発明は、構造体に面板を取り付ける面板取付部材１、及び面板取付部材１を用いた内装構造であり、当然ながら構造体が天井２に限定されるわけではないが、便宜上、本実施形態では天井に面板を取り付ける例で説明している。 (overall structure)
FIG. 1 is a perspective view of a state in which the face plate mounting member 1 of the present invention is installed on the ceiling surface 2a as viewed from below. The face plate as used herein refers to a wall plate or floor plate that is attached to the indoor side of a structure such as a floor, a structural wall, or a pillar that constitutes a building, and the face plate attachment material 1 is for attaching the face plate to the ceiling surface 2a. belongs to. As shown in this figure, the face plate mounting material 1 is fixed to the ceiling surface 2a, the face plate is installed on the face plate mounting material 1 (for convenience, the face plate is omitted in this figure), so to speak, the face plate is interposed via the face plate mounting material 1. And attached to the ceiling surface 2a. The present invention is a face plate attachment member 1 for attaching a face plate to a structure and an interior structure using the face plate attachment member 1, and the structure is not limited to the ceiling 2 as a matter of course. In the example, the face plate is attached to the ceiling.

図１に示すように面板取付部材１は、平面視で概ね四辺形であり、長手方向を有する長尺部材である。以下は便宜上、長手方向を「軸方向」と呼び、この軸方向と直交する方向を「幅方向」と呼ぶこととする。図１では、軸方向を矢印Ｘで、幅方向を矢印Ｙで示している。 As shown in FIG. 1, the face plate mounting member 1 is a long member having a substantially quadrangular shape in a plan view and having a longitudinal direction. Hereinafter, for the sake of convenience, the longitudinal direction is referred to as an “axial direction”, and the direction orthogonal to the axial direction is referred to as a “width direction”. In FIG. 1, the axial direction is indicated by an arrow X, and the width direction is indicated by an arrow Y.

図２は、面板取付部材１を幅方向で切った断面図である。なお便宜上、この図では図１とは上下を反転させて表している。図２に示すように面板取付部材１は、中央付近に配置される設置面３と、設置面３の両端側に設けられる２箇所の係止面４と、設置面３とそれぞれの係止面４との間に設けられる２箇所の屈曲部５で形成されている。また、設置面３と係止面４には断面視で概ね直線状の軸線があり、それぞれの軸線は略平行であるが同一直線状には並ばない配置であり、つまり上段（図２では設置面３）と下段（図２では係止面４）といったように、設置面３と係止面４は高さを違えるように配置されている。 FIG. 2 is a cross-sectional view of the face plate mounting member 1 cut in the width direction. For convenience, this figure is shown upside down from FIG. As shown in FIG. 2, the face plate mounting member 1 includes an installation surface 3 disposed near the center, two locking surfaces 4 provided on both ends of the installation surface 3, and the installation surface 3 and the respective locking surfaces. 4 is formed with two bent portions 5 provided between the two. In addition, the installation surface 3 and the locking surface 4 have a substantially straight axis in a cross-sectional view, and each axis is substantially parallel but is not arranged in the same straight line. The installation surface 3 and the locking surface 4 are arranged so as to have different heights, such as the surface 3) and the lower stage (the locking surface 4 in FIG. 2).

図１に示すように面板取付部材１は、２箇所の係止面４を天井面２ａに接触させて天井２に固定される。このとき、あらかじめビス孔６を係止面４の軸方向に所定間隔で設け、これを利用して面板取付部材１を天井面２ａにビス固定することができる。もちろん、これに限らず従来から用いられる公知の固定手段によって、面板取付部材１を天井面２ａに固定することもできる。 As shown in FIG. 1, the face plate mounting member 1 is fixed to the ceiling 2 with two locking surfaces 4 in contact with the ceiling surface 2 a. At this time, the screw holes 6 are previously provided in the axial direction of the locking surface 4 at a predetermined interval, and the face plate mounting member 1 can be screwed to the ceiling surface 2a using this. Of course, not limited to this, the face plate mounting member 1 can be fixed to the ceiling surface 2a by known fixing means used conventionally.

また、図１に示すように面板取付部材１のうち設置面３には、幅方向に延びる幅溝部７ａと、幅方向両端側に配置される軸溝部７ｂを設けることもできる。これらを幅溝部７ａや軸溝部７ｂを設けることによって設置面３の断面係数を大きくし、有害な局所的変形を防止することができるので好適である。設置面３に配設された多数の孔または細密な凸凹部は、面板を設置する際に用いられる打付け釘を案内するための打付け孔８である。 Further, as shown in FIG. 1, the installation surface 3 of the face plate mounting member 1 may be provided with a width groove portion 7 a extending in the width direction and shaft groove portions 7 b arranged at both ends in the width direction. By providing these with the width groove portion 7a and the shaft groove portion 7b, the section modulus of the installation surface 3 can be increased, and harmful local deformation can be prevented. A large number of holes or fine convex and concave portions provided on the installation surface 3 are driving holes 8 for guiding a driving nail used when the face plate is installed.

一般的に直上階からの騒音は、打撃等によって加えられた衝撃が固体音となって階下に伝えられることで生ずる。より具体的には、加えられた衝撃が、床や周壁などの構造体を固体伝搬し（伝搬速度は秒速数千ｍともいわれる）、構造体から放出された固体音は空気を振動させ、さらに面板を振動させ、結果的に一次固体音として階下（室内）に伝達される。一方、構造体を伝搬した固体音は直接面板に伝わるので、これに伴って面板は振動し、結果的に二次固体音として階下に伝達される。これら一次固体音と二次固体音とが合成され、階下にいる人に騒音となって伝達される。 In general, noise from directly above the floor is generated when an impact applied by striking or the like is transmitted as a solid sound to the downstairs. More specifically, the applied impact propagates through a structure such as a floor or a peripheral wall (the propagation speed is also referred to as several thousand meters per second), the solid sound emitted from the structure vibrates the air, and the face plate As a result, it is transmitted to the downstairs (room) as a primary solid sound. On the other hand, since the solid sound propagated through the structure is directly transmitted to the face plate, the face plate vibrates accordingly, and as a result, is transmitted to the downstairs as a secondary solid sound. These primary solid sounds and secondary solid sounds are synthesized and transmitted as noise to people downstairs.

本願発明では図１や図２に示すような構成、つまり面板取付材１の屈曲部５が弾性変形しやすく、その結果面板が天井に弾性固定されることになるので、一次固体音と二次固体音を低減することができる。すなわち、一次固体音や二次固体音を発生させる面板の微振動は、屈曲部５が弾性変形することで容易に吸収され、放出される騒音は著しく低減される。このように、内装版取付け部において、屈曲部５の弾性変形によって音圧エネルギーを運動エネルギーに変換することで固体音を低減させる技術は、従来にはなかったもので、とくに二次固体音を低減させることができるという効果はこれまでに見られなかった極めて有利な効果である。 In the present invention, the configuration as shown in FIGS. 1 and 2, that is, the bent portion 5 of the face plate mounting material 1 is easily elastically deformed, and as a result, the face plate is elastically fixed to the ceiling. Solid sound can be reduced. That is, the slight vibration of the face plate that generates the primary solid sound and the secondary solid sound is easily absorbed by the elastic deformation of the bent portion 5, and the emitted noise is remarkably reduced. In this way, the technology for reducing the solid sound by converting the sound pressure energy into the kinetic energy by the elastic deformation of the bent portion 5 in the interior plate mounting portion has never existed in the past. The effect that it can be reduced is a very advantageous effect that has not been seen so far.

なお面板取付材１は、天井面２ａに直接固定する場合に限らず、天井面２ａに設置された他の部材を介して固定することもできる。図３は、天井面２ａに不陸調整用として設置された受け材９に、面板取付材１を固定した状態を示す斜視図である。このような構成とすることで、仮に天井面２ａに不陸があっても、受け材９の効果で、面板取付材１を平坦に取り付けることが可能となり、しかも床から面板までの距離があるため一次固体音のうちの短周期成分を低減させることができるという効果も期待できる。なお受け材９は、溝形鋼を用いることができるが、これに限らず、天井面２ａの不陸を調整できて所定の空間を設けることができるものであれば種々の材料を使用することができる。 The face plate attachment material 1 is not limited to being directly fixed to the ceiling surface 2a, but can also be fixed via another member installed on the ceiling surface 2a. FIG. 3 is a perspective view showing a state in which the face plate attachment material 1 is fixed to the receiving material 9 installed for adjusting the unevenness on the ceiling surface 2a. By adopting such a configuration, even if the ceiling surface 2a is uneven, it is possible to attach the face plate mounting material 1 flatly by the effect of the receiving material 9, and there is a distance from the floor to the face plate. Therefore, the effect that the short period component of the primary solid sound can be reduced can also be expected. In addition, although the grooved steel can be used for the receiving material 9, not only this but various materials should be used if the unevenness of the ceiling surface 2a can be adjusted and a predetermined space can be provided. Can do.

また、階下における直接の音源である面板の振動を抑える、つまり音圧レベル（音のエネルギーを示すｄＢ（Ｃ）値）を抑制することは、騒音レベル（人が聴覚により感じる音の量でｄＢ（Ａ）値）を減少させることに加えて、特に低周波音領域で残響時間を短縮できるという効果もある。このような現象は、「ガラス版などで板振動を行う壁体でも低音域から中音域にかけて残響時間が減少する（松井昌幸著『音響材料（上）』：彰国社）」と言われていることからも理解できる。従来吸音材量として用いられていたグラスウールなどの多孔質材料は、もっぱら高周波音吸収用として利用されており、低周波音を吸収することは難しかった。しかしながら本願発明では、固体音のうち低周波音といわれる二次固体音を低減させることができるので、これまでにはない防音技術を提供できることとなる。 Further, suppressing the vibration of the face plate which is a direct sound source in the downstairs, that is, suppressing the sound pressure level (dB (C) value indicating sound energy) is the noise level (the amount of sound that a person feels by hearing in dB). In addition to reducing (A) value, there is also an effect that the reverberation time can be shortened particularly in a low frequency sound region. Such a phenomenon is said to be "the reverberation time decreases from low to mid-range even on a wall that vibrates plate with a glass plate (Masayuki Matsui, Acoustic Materials (above): Shokokusha)". I can understand that. Conventionally, porous materials such as glass wool, which have been used as the amount of sound absorbing material, are exclusively used for absorbing high frequency sound, and it has been difficult to absorb low frequency sound. However, in this invention, since the secondary solid sound called a low frequency sound among solid sounds can be reduced, the soundproofing technique which has not existed until now can be provided.

以下、構成要素ごとに詳細に説明する。 Hereinafter, each component will be described in detail.

（面板取付部材）
まず、図２及び図４〜図６に基づいて、面板取付部材１について説明する。面板取付部材１は、図１に示すように平面視では、幅方向（矢印Ｙ）に比べて軸方向（矢印Ｘ）に長い略四辺形を呈している。また面板取付部材１は、図２に示すように断面視では、中央にひとつの設置面３が配置され、その両脇にあって設置面３とは段差がつくように２つの係止面４が設けられ、設置面３と係止面４との間にはそれぞれ屈曲部５が形成されている。これら設置面３と係止面４と屈曲部５は、ひとつの帯板から一体の物として加工することができる。もちろんそれぞれ別体として形成し、後に溶接等により一体とすることもできるが、その場合、屈曲部５を介して全体が一体となって弾性挙動するように製作する必要がある。また面板取付部材１は、弾性材（強度があり弾性変形しやすい材料）で作成されることが望ましく、少なくとも屈曲部５は上記弾性材からなることとするのがよい。 (Face plate mounting member)
First, the face plate mounting member 1 will be described with reference to FIGS. 2 and 4 to 6. As shown in FIG. 1, the face plate mounting member 1 has a substantially quadrilateral shape that is longer in the axial direction (arrow X) than in the width direction (arrow Y) in plan view. In addition, the face plate mounting member 1 has, as shown in FIG. 2, two locking surfaces 4 so that a single installation surface 3 is disposed in the center in a cross-sectional view and a step is formed on both sides of the installation surface 3. And a bent portion 5 is formed between the installation surface 3 and the locking surface 4. The installation surface 3, the locking surface 4, and the bent portion 5 can be processed as one piece from a single strip. Of course, they can be formed as separate bodies and integrated later by welding or the like. However, in that case, it is necessary to manufacture them so as to be elastic as a whole through the bent portion 5. The face plate mounting member 1 is preferably made of an elastic material (a material having strength and easily elastically deformed), and at least the bent portion 5 is preferably made of the elastic material.

１．設置面
設置面３は、面板を設置するためのものであり、全体的に平坦な平面で形成されている。前述したとおり設置面３には、有害な局所的変形を防止する幅溝部７ａ（図１）や軸溝部７ｂ（図１）を設けることもできるし、面板設置用の打付け釘を案内するための打付け孔８（図１）または細密な凸凹部を多数設けることもできる。 1. Installation surface The installation surface 3 is for installing a face plate, and is formed as a flat surface as a whole. As described above, the installation surface 3 can be provided with a width groove portion 7a (FIG. 1) and a shaft groove portion 7b (FIG. 1) for preventing harmful local deformation, and to guide a driving nail for installing the face plate. It is also possible to provide a large number of fine holes 8 (FIG. 1) or fine convex and concave portions.

２．係止面
係止面４は、面板取付部材１を天井面２ａに固定するためのものであり、設置面３同様全体的に平坦な平面で形成されている。図２に示すように係止面４は、設置面３の幅方向における両端部側にそれぞれ１箇所ずつ設けられており、間に屈曲部５を設けるため設置面３とは段差が設けられている。具体的には、設置面３が略水平かつ上面となるように面板取付部材１を置くと、係止面４と設置面３との間には高低差（この高低差に屈曲部５が設けられる）が生じ、設置面３が上段で係止面４が下段といった状態になる。また、天井面２ａと面板が略平行配置されるように、設置面３と係止面４は略平行配置となっている。 2. Locking surface The locking surface 4 is for fixing the face plate mounting member 1 to the ceiling surface 2 a, and is formed as a flat surface as a whole like the installation surface 3. As shown in FIG. 2, the locking surface 4 is provided at each of the both end portions in the width direction of the installation surface 3, and a step is provided from the installation surface 3 because the bent portion 5 is provided therebetween. Yes. Specifically, when the face plate mounting member 1 is placed so that the installation surface 3 is substantially horizontal and the upper surface, a height difference between the locking surface 4 and the installation surface 3 (a bent portion 5 is provided at this height difference). The installation surface 3 is in the upper stage and the locking surface 4 is in the lower stage. Further, the installation surface 3 and the locking surface 4 are arranged substantially in parallel so that the ceiling surface 2a and the face plate are arranged substantially in parallel.

図２に示すように、係止面４には凸溝１０を設けることもできる。この凸溝１０は、断面係数を大きくして、外力による生ずる応力を軽減することを目的として設けられる。図２では、片側の係止面４につき２箇所の凸溝１０（両側で４箇所）が設けられているが、その設置箇所数や形状は任意に設計できる。また図２に示すように、係止面４の端部を略１８０度反転させた曲げ縁部１１を設け、端部補強を図ることもできる。 As shown in FIG. 2, a convex groove 10 can be provided on the locking surface 4. The convex groove 10 is provided for the purpose of increasing the section modulus and reducing the stress caused by the external force. In FIG. 2, two convex grooves 10 (four locations on both sides) are provided for one locking surface 4, but the number and shape of the installation locations can be arbitrarily designed. Moreover, as shown in FIG. 2, the edge part reinforcement can also be aimed at by providing the bending edge part 11 which reversed the edge part of the latching surface 4 about 180 degree | times.

３．屈曲部
屈曲部５は、設置面３と係止面４との間に設けられるものであって、ここでの弾性変形によって例えば面板の振動を吸収するものである。図２に示すように屈曲部５は、設置面３の幅方向における両端部側に連続して設けられ、さらに係止面４とも連続している。言い換えれば、屈曲部５の一端は設置面３と連続しており、屈曲部５の他端は係止面４と連続している。 3. Bending portion The bending portion 5 is provided between the installation surface 3 and the locking surface 4 and absorbs vibrations of the face plate, for example, by elastic deformation. As shown in FIG. 2, the bent portion 5 is continuously provided on both end sides in the width direction of the installation surface 3, and is further continuous with the locking surface 4. In other words, one end of the bent portion 5 is continuous with the installation surface 3, and the other end of the bent portion 5 is continuous with the locking surface 4.

また図２に示すように、屈曲部５は第１折返し部５ａと第２折返し部５ｂによって構成されている。この第１折返し部５ａは、設置面３と連続する側の端部に設けられ、断面視で略半円形を呈している。一方、第２折返し部５ｂは、係止面４と連続する側の端部に設けられ、やはり断面視で略半円形を呈している。 As shown in FIG. 2, the bent portion 5 is composed of a first folded portion 5a and a second folded portion 5b. The first folded portion 5a is provided at an end portion on the side continuous with the installation surface 3, and has a substantially semicircular shape in a sectional view. On the other hand, the 2nd folding | turning part 5b is provided in the edge part of the side continuous with the latching | locking surface 4, and is also exhibiting the substantially semicircle by sectional view.

第１折返し部５ａと第２折返し部５ｂは、ともに断面視で半円形を呈しているが、両者の屈曲方向は反転しており、つまり、第１折返し部５ａは設置面３の幅方向内側に中心を持つ半円形であり、第２折返し部５ｂは設置面３の幅方向外側に中心を持つ半円形である。なお、以下は便宜上、図２のような第１折返し部５ａの形状を「外カーブ」と、第２折返し部５ｂの形状を「内カーブ」と呼ぶ。 The first folded portion 5a and the second folded portion 5b are both semicircular in sectional view, but their bending directions are reversed, that is, the first folded portion 5a is on the inner side in the width direction of the installation surface 3. The second folded portion 5 b is a semicircle having a center on the outer side in the width direction of the installation surface 3. Hereinafter, for convenience, the shape of the first folded portion 5a as shown in FIG. 2 is referred to as an “outer curve”, and the shape of the second folded portion 5b is referred to as an “inner curve”.

図２では、設置面３の軸線と第１折返し部５ａの軸線（円の接線方向）とが略同一直線状にあり、係止面４の軸線と第２折返し部５ｂの軸線（円の接線方向）とが略同一直線状にある。しかも、第１折返し部５ａと第２折返し部５ｂが接続する点（言い換えれば、第１折返し部５ａから第２折返し部５ｂに変化する点）である反曲点５ｃでは、第１折返し部５ａの軸線と第２折返し部５ｂの軸線とが略同一直線状にある。しかしながら本願発明の面板取付部材１を構成する屈曲部５は、必ずしもこのような厳密な形状とする必要はなく、さらに第１折返し部５ａと第２折返し部５ｂが半円である必要もなく、弾性変形しやすいように、内側に折り返される（外カーブの）第１折返し部５ａと、外側に折り返される（内カーブの）第２折返し部５ｂとが設けられればよい。 In FIG. 2, the axis of the installation surface 3 and the axis of the first folded portion 5a (the tangential direction of the circle) are substantially collinear, and the axis of the locking surface 4 and the axis of the second folded portion 5b (the tangent of the circle) Direction) is substantially the same straight line. Moreover, at the inflection point 5c, which is a point where the first folded part 5a and the second folded part 5b are connected (in other words, a point where the first folded part 5a changes to the second folded part 5b), the first folded part 5a. And the axis of the second folded portion 5b are substantially in the same straight line. However, the bent portion 5 constituting the face plate mounting member 1 of the present invention does not necessarily have such a strict shape, and the first folded portion 5a and the second folded portion 5b do not need to be semicircles. In order to be easily elastically deformed, it is only necessary to provide a first folded portion 5a that is folded inward (outer curve) and a second folded portion 5b that is folded outward (inner curve).

屈曲部５は外部から受ける振動によって破断しない程度の強度が求められる一方で、弾性変形を生じやすいという機能も求められる。そこで、屈曲部５にスリット（以下、「細長孔１２」という。）を設けることができる。図４は、屈曲部５に細長孔１２を設けた面板取付部材１を幅方向で切った断面図である。この図に示すように細長孔１２は、第１折返し部５ａと第２折返し部５ｂが接続する反曲点５ｃ付近に設けられるものであり、軸方向に延びる細長形状を呈している。このように、反曲点５ｃ付近に細長孔１２を設けるのは、反曲点５ｃ付近は他に比べて生じる変形量が小さく、最も強度上問題とならない位置だからである。なお細長孔１２は、面板取付部材１の軸方向における端部から端部まで一連して形成することもできるし、断続的に複数箇所に形成することもできる。 The bent portion 5 is required to have a strength that does not break due to vibrations received from the outside, but also has a function of easily causing elastic deformation. Therefore, a slit (hereinafter referred to as “elongated hole 12”) can be provided in the bent portion 5. FIG. 4 is a cross-sectional view of the face plate mounting member 1 provided with the elongated holes 12 in the bent portion 5 in the width direction. As shown in this figure, the elongated hole 12 is provided in the vicinity of the inflection point 5c where the first folded portion 5a and the second folded portion 5b are connected, and has an elongated shape extending in the axial direction. The elongate hole 12 is provided in the vicinity of the inflection point 5c in this way because the deformation amount in the vicinity of the inflection point 5c is small compared to others and is the position where there is no problem in strength. In addition, the elongate hole 12 can also be formed in series from the edge part to the edge part in the axial direction of the faceplate attachment member 1, and can also be formed in multiple places intermittently.

屈曲部５を構成する第１折返し部５ａと第２折返し部５ｂは、それぞれ断面視で折り返した形状となっており、つまり折返しによって内部に隙間部ができる。図４では、第１折返し部５ａによって形成される第１隙間部５１と、第２折返し部５ｂによって形成される第２隙間部５２を示している。第１隙間部５１や第２隙間部５２が大きいスペースとなるほど、それぞれの折返しの曲率が小さくなり、屈曲部５は弾性変形を生じやすくなる。 The first folded portion 5a and the second folded portion 5b that constitute the bent portion 5 have shapes that are folded in a sectional view, that is, a gap is formed inside by folding. In FIG. 4, the 1st clearance gap part 51 formed of the 1st folding | returning part 5a and the 2nd clearance gap part 52 formed of the 2nd folding | returning part 5b are shown. The larger the first gap portion 51 and the second gap portion 52 are, the smaller the curvature of each turn, and the bent portion 5 is more likely to be elastically deformed.

しかしながら他方では、隙間部のスペースが大きいほど屈曲部５の高さは大きくなり、面板取付部材１の厚さも大きくなる。面板取付部材１を設置する場所によっては、面板取付部材１の厚さを小さくしたい場合もある。そこで、第１折返し部５ａ又は第２折返し部５ｂのどちらか一方の折返しの曲率を大きくして、つまり第１隙間部５１又は第２隙間部５２のどちらか一方のスペースを小さくして、面板取付部材１の厚さを小さくすることができる。この場合でも、第１隙間部５１又は第２隙間部５２のどちらか一方は、図２や図４に示す隙間部と同等なので、弾性変形を生じやすいという機能は大きく損なわれない。 On the other hand, however, the height of the bent portion 5 increases as the space of the gap portion increases, and the thickness of the face plate mounting member 1 also increases. Depending on the location where the face plate mounting member 1 is installed, it may be desired to reduce the thickness of the face plate mounting member 1. Therefore, the curvature of one of the first folded portion 5a or the second folded portion 5b is increased, that is, the space of either the first gap portion 51 or the second gap portion 52 is reduced, and the face plate The thickness of the attachment member 1 can be reduced. Even in this case, since one of the first gap 51 and the second gap 52 is equivalent to the gap shown in FIGS. 2 and 4, the function of easily causing elastic deformation is not greatly impaired.

図５は、第１折返し部５ａ内に狭隘隙間部５１ｓを設けた面板取付部材１を幅方向で切った断面図である。この図に示すように、第１折返し部５ａの折返しの曲率を大きくして、第１折返し部５ａ内に狭隘隙間部５１ｓを設けると、面板取付部材１の厚さｔを著しく低減できる。もちろん、第１折返し部５ａ内に狭隘隙間部５１ｓを設けるのに代えて、第２折返し部５ｂ内に狭隘隙間部を設けることもできる。 FIG. 5 is a cross-sectional view of the face plate attachment member 1 provided with a narrow gap 51s in the first folded portion 5a, cut in the width direction. As shown in this figure, the thickness t of the face plate mounting member 1 can be remarkably reduced by increasing the curvature of the first folded portion 5a and providing the narrow gap portion 51s in the first folded portion 5a. Of course, instead of providing the narrow gap portion 51s in the first folded portion 5a, a narrow gap portion may be provided in the second folded portion 5b.

図６は、第１折返し部５ａ内の狭隘隙間部５１ｓに緩衝部材１３を設けた面板取付部材１を幅方向で切った断面図である。この図に示すように、第１折返し部５ａ内に狭隘隙間部５１ｓを設けた結果、屈曲部５の弾性変形性能がやや損なわれたことを補うために、緩衝部材１３を設けることができる。この緩衝部材１３は、吸音性能を発揮するためにゴムなどの弾性材であることが望ましく、例えばゴム状弾性シートが適している。また、緩衝部材１３は、狭隘隙間部５１ｓの中に挟持させるとよい。第２折返し部５ｂ内に狭隘隙間部を設けた場合は、その中に挟持させるとよい。また、狭隘隙間部５１ｓに限らず、図２や図４に示す第１隙間部５１や第２折返し部５ｂ内に、緩衝部材１３を設置することもできる。このように、面板取付部材１に緩衝部材１３を設けると、サージング（共振時に生じる一種の騒音）を防止し得るという効果が期待できる。 FIG. 6 is a cross-sectional view of the face plate mounting member 1 provided with the buffer member 13 in the narrow gap portion 51s in the first folded portion 5a in the width direction. As shown in this figure, the buffer member 13 can be provided in order to compensate that the elastic deformation performance of the bent portion 5 is somewhat impaired as a result of providing the narrow gap portion 51s in the first folded portion 5a. The buffer member 13 is desirably an elastic material such as rubber in order to exhibit sound absorbing performance, and for example, a rubber-like elastic sheet is suitable. The buffer member 13 may be sandwiched in the narrow gap portion 51s. When a narrow gap portion is provided in the second folded portion 5b, it is preferable to sandwich the narrow gap portion therein. Further, the buffer member 13 can be installed not only in the narrow gap portion 51 s but also in the first gap portion 51 and the second folded portion 5 b shown in FIGS. 2 and 4. As described above, when the buffer member 13 is provided on the face plate mounting member 1, an effect that surging (a kind of noise generated during resonance) can be prevented can be expected.

（内装構造）
つぎに、図７〜図１０に基づいて、面板取付部材１を用いた内装構造について説明する。図７は、天井２に形成された内装構造を示す断面図である。この図に示すように、本願発明の内装構造は、前記した本願発明の面板取付部材１と、面板１４によって構成される。 (Interior structure)
Below, based on FIGS. 7-10, the interior structure using the faceplate attachment member 1 is demonstrated. FIG. 7 is a cross-sectional view showing the interior structure formed on the ceiling 2. As shown in this figure, the interior structure of the present invention is composed of the above-described face plate mounting member 1 and face plate 14 of the present invention.

通常、多数の面板取付部材１は天井２に設置されており、これらの面板取付部材１も略平行に配置され、図７では紙面に対して垂直方向に平行して並べられている。またこの図では、面板取付部材１が２箇所の係止面４を天井面２ａに接触させ、ビス１５によって固定されているが、これに限らず従来から用いられる公知の固定手段によって固定できるのは前述のとおりである。 Usually, a large number of face plate mounting members 1 are installed on the ceiling 2, and these face plate mounting members 1 are also arranged substantially in parallel, and in FIG. Further, in this figure, the face plate mounting member 1 has two locking surfaces 4 in contact with the ceiling surface 2a and is fixed by screws 15, but is not limited thereto, and can be fixed by a conventionally known fixing means. Is as described above.

通常、多数の面板取付部材１が天井２に設置され、これらの面板取付部材１は略平行に配置され、図７では紙面に対して垂直方向に平行して並べられている。またこの図では、面板取付部材１が２箇所の係止面４を天井面２ａに接触させ、ビス１５によって固定されているが、これに限らず従来から用いられる公知の固定手段によって固定できるのは前述のとおりである。 Usually, a large number of face plate mounting members 1 are installed on the ceiling 2, and these face plate mounting members 1 are arranged substantially in parallel, and in FIG. Further, in this figure, the face plate mounting member 1 has two locking surfaces 4 in contact with the ceiling surface 2a and is fixed by screws 15, but is not limited thereto, and can be fixed by a conventionally known fixing means. Is as described above.

図７では紙面に対して垂直方向（奥行方向）に、面板取付部材１の軸方向が向くように配置されているが、面板取付部材１の配置方向は特に限定されるものではなく、例えば図７で、面板取付部材１の軸方向が紙面上の左右方向に向くように配置することもできる。通常、面板１４も軸方向に長い長尺部材であり、この場合、面板取付部材１の軸方向と面板１４の長手方向が直交するように配置される。例えば図７の場合では、面板取付部材１の軸方向が紙面に対して垂直方向に配置され、面板１４の長手方向が紙面上の左右方向に向くように配置される。もちろん、面板１４の幅が広い場合、あるいは面板取付部材１の配置間隔が短い場合など、面板取付部材１の軸方向と面板１４の長手方向が平行するように配置することもできる。面板１４は、打付け釘などによって、面板取付部材１の設置面３（図７では面板取付部材１の下面）に設置される。 In FIG. 7, the face plate mounting member 1 is arranged so that the axial direction of the face plate mounting member 1 is oriented in a direction perpendicular to the paper surface (depth direction), but the arrangement direction of the face plate mounting member 1 is not particularly limited. 7, the face plate mounting member 1 can be arranged so that the axial direction of the face plate mounting member 1 is directed in the left-right direction on the paper surface. Usually, the face plate 14 is also a long member that is long in the axial direction, and in this case, the face plate mounting member 1 is arranged so that the axial direction of the face plate 14 and the longitudinal direction of the face plate 14 are orthogonal to each other. For example, in the case of FIG. 7, the axial direction of the face plate mounting member 1 is arranged in a direction perpendicular to the paper surface, and the longitudinal direction of the face plate 14 is arranged in the left-right direction on the paper surface. Of course, when the width | variety of the faceplate 14 is wide, or when the arrangement | positioning space | interval of the faceplate attachment member 1 is short, it can also arrange | position so that the axial direction of the faceplate attachment member 1 and the longitudinal direction of the faceplate 14 may be parallel. The face plate 14 is installed on the installation surface 3 of the face plate mounting member 1 (the lower surface of the face plate mounting member 1 in FIG. 7) by a driving nail or the like.

図７では、壁１６の屋内側に面板１７が取り付けられ、天井２に取り付けられた面板１４との接合部では、廻り縁１８が設置されている。このように廻り縁１８を使用して見切っておくと、音響的、意匠的にも好適である。 In FIG. 7, a face plate 17 is attached to the indoor side of the wall 16, and a peripheral edge 18 is provided at a joint portion with the face plate 14 attached to the ceiling 2. In this way, it is preferable from the viewpoint of acoustics and design that the surrounding edge 18 is used.

図８は、壁１６に形成された内装構造を示す断面図である。この図に示すように、本願発明の内装構造は、天井に限らず壁１６をはじめとする種々の構造体に形成することができる。壁１６に内装構造を形成する場合、水平方向または鉛直方向に面板取付部材１を平行配置し、２箇所の係止面４を壁１６表面に接触させ、ビス１５等によって固定する。そして、面板１７を鉛直方向または水平方向に配置し、面板取付部材１の設置面３に接触させて、打付け釘などによって面板取付部材１に設置する。この場合も、天井２に取り付けられた面板１４と面板１７との接合部では、廻り縁１８を設置することが望ましい。 FIG. 8 is a cross-sectional view showing the interior structure formed on the wall 16. As shown in this figure, the interior structure of the present invention can be formed not only on the ceiling but also on various structures including a wall 16. When the interior structure is formed on the wall 16, the face plate mounting member 1 is arranged in parallel in the horizontal direction or the vertical direction, the two locking surfaces 4 are brought into contact with the surface of the wall 16, and are fixed by screws 15 or the like. Then, the face plate 17 is arranged in the vertical direction or the horizontal direction, is brought into contact with the installation surface 3 of the face plate attachment member 1, and is installed on the face plate attachment member 1 with a driving nail or the like. Also in this case, it is desirable to install a peripheral edge 18 at the joint between the face plate 14 and the face plate 17 attached to the ceiling 2.

図９は、木造壁組工法における内装構造を示す断面図である。本願発明の内装構造は、木造壁組工法（いわゆる２×４工法）による木造建築物でも実施することができる。木造壁組工法による木造建築物であっても、面板取付部材１の構成は図２及び図４〜図６に基づいて説明したとおりであり、面板取付部材１の配置方法や固定方法、あるいは面板１４の配置方法や設置方法は、図７〜図８に基づいて説明した内容と同様である。また、天井２に取り付けられた面板１４と面板１７との接合部で、廻り縁１８を設置することが望ましいことも同じである。 FIG. 9 is a cross-sectional view showing the interior structure in the wooden wall assembling method. The interior structure of the present invention can also be implemented in a wooden building by a wooden wall assembling method (so-called 2 × 4 method). Even if it is a wooden building by a wooden wall construction method, the structure of the faceplate attachment member 1 is as having demonstrated based on FIG.2 and FIG.4-FIG.6, and the arrangement method of the faceplate attachment member 1, a fixing method, or a faceplate The arrangement method and installation method 14 are the same as those described with reference to FIGS. Further, it is also desirable that the peripheral edge 18 is desirably installed at the joint portion between the face plate 14 and the face plate 17 attached to the ceiling 2.

木造壁組工法で特徴的なのは、本工法特有の梁材１９に係止面４を固定することが望ましいことである。これにより、面板取付部材１を堅固に天井面２ａに固定することができる。なお、梁材１９の軸方向と面板取付部材１の軸方向が直交するように配置される場合は、梁材１９と係止面４が交差する箇所で固定し、図９のように梁材１９の軸方向と面板取付部材１の軸方向が略平行するように配置される場合は、左右２箇所ある係止面４のうちどちらか一方を梁材１９の直下となるように配置して固定するのがよい。 What is characteristic of the wooden wall assembling method is that it is desirable to fix the locking surface 4 to the beam material 19 unique to this method. Thereby, the faceplate attaching member 1 can be firmly fixed to the ceiling surface 2a. In addition, when it arrange | positions so that the axial direction of the beam material 19 and the axial direction of the faceplate attachment member 1 may orthogonally cross, it fixes in the location where the beam material 19 and the latching surface 4 cross | intersect, and it is shown in FIG. When the axial direction of 19 and the axial direction of the face plate mounting member 1 are arranged so as to be substantially parallel, either one of the two locking surfaces 4 on the left and right sides is arranged directly below the beam member 19. It is good to fix.

図１０は、吊木２０で受け材９を懸架した場合の木造壁組工法における内装構造を示す断面図である。この図に示すように、天井面２ａに代えて、吊木２０で懸架した受け材９に面板取付部材１を固定することもできる。この場合、天井面２ａの不陸を調整できるうえ、天井面２ａから面板１４まで距離があるため一次固体音を低減させることができるという効果も期待できる。なお、受け材９は吊木で懸架してもよく、また受け材９として溝形鋼を用いることができるが、これに限らず種々の材料を使用することができるのは前記したとおりである。 FIG. 10 is a cross-sectional view showing the interior structure in the wooden wall assembling method when the receiving material 9 is suspended by the hanging tree 20. As shown in this figure, instead of the ceiling surface 2a, the face plate mounting member 1 can be fixed to a receiving material 9 suspended by a hanging tree 20. In this case, the unevenness of the ceiling surface 2a can be adjusted, and since the distance from the ceiling surface 2a to the face plate 14 is large, an effect that primary solid sound can be reduced can be expected. The receiving material 9 may be suspended by a hanging tree, and a grooved steel can be used as the receiving material 9, but not limited to this, various materials can be used as described above. .

本願発明の面板取付部材と内装構造は、マンションなどの集合住宅やオフィスビルで利用できるほか、校舎や倉庫などあらゆる多層階の建築物で利用することが可能である。放送施設や映画館、コンサートホールなど固体音による騒音が極めて妨げとなる建築物には、とくに有効である。 The face plate mounting member and the interior structure of the present invention can be used in a multi-storey building such as a school building or a warehouse, in addition to being usable in an apartment house such as a condominium or an office building. This is particularly effective for buildings where noise caused by solid sound is extremely disturbing, such as broadcasting facilities, movie theaters, and concert halls.
