Description

本発明は,例えば道路等の対面する建造物に反射した反射屋外騒音を庇,ベランダスラブ等の屋外天井面で反射して高層階の室内に至るのを防止するように用いるマンション等建造物の反射屋外騒音再反射用天井パネル及びこれを設置したマンション等の建造物に関する。   The present invention, for example, is used for a building such as a condominium used to prevent reflection outdoor noise reflected on a building facing a road or the like from being reflected on an outdoor ceiling such as a veranda slab to reach a higher floor room. The present invention relates to a reflection outdoor noise re-reflection ceiling panel and a building such as a condominium in which the same is installed.

例えば鉄道沿いの建造物の室内に鉄道を走行する車両が発する騒音が伝搬するのを防止する目的で,室内側に向けて下降傾斜した平行多数の反射面とこれらの上下端間の垂直な連結面を断面鋸刃状をなすように交互に配置した反射パネルを,ベランダスラブの屋外天井面に設置し,該反射パネルの室内側に向けて傾斜した反射面によって鉄道車両の騒音を室内側に下降傾斜する反射面によって室外側に向けて反射するようにしたマンション等の建造物が提案されている。   For example, in order to prevent the noise generated by vehicles traveling on the railway from propagating to the interior of the building along the railway, a number of parallel reflecting surfaces that are inclined downward toward the indoor side and the vertical connection between these upper and lower ends. Reflective panels with their surfaces arranged alternately in a sawtooth shape are installed on the outdoor ceiling surface of the veranda slab, and the noise of railway vehicles is introduced indoors by the reflective surface inclined toward the indoor side of the reflective panel. A building such as an apartment has been proposed in which the reflecting surface is inclined downward and reflected toward the outside of the room.

しかし乍らこの場合,室内側に向けて下降傾斜した反射面に対する上記騒音は,最も室外側に位置するものにあっては室外側に反射することが可能であるが,その余の多数の室内側に向けて下降傾斜した反射面にあっては,該騒音が該反射面によって入射角と同一角度で反射して垂直な連結面に至り,該垂直な連結面によって室内側に向けて再度反射されて室内に至る結果となり,従って上記反射パネルを屋外天井面に設置しても,該騒音が室内側に伝搬するのを防止することができないことになる。   However, in this case, the noise on the reflecting surface that is inclined downward toward the indoor side can be reflected to the outdoor side if it is located at the outermost side. In the case of a reflective surface inclined downward toward the inside, the noise is reflected by the reflective surface at the same angle as the incident angle and reaches a vertical connecting surface, and is reflected again toward the indoor side by the vertical connecting surface. Therefore, even if the reflection panel is installed on the outdoor ceiling surface, the noise cannot be prevented from propagating indoors.

例えば,国道沿いのマンション,私鉄沿いのマンション等は,道路,鉄道を挟んで対面する建造物が存在しているのが通常であるところ,道路や鉄道の車両の騒音は下層階と同様に高層階の室内にも伝搬して居住者の悩みとなっているが,下層階と同様に高層階に車両の騒音が伝搬するのは,図1に示すように該騒音が対面する建造物に反射して幅広の角度で屋外天井面に至り,屋外天井面から室内側に対して反射されるためと見られるところ,上記従来のものにあって該騒音の室内側への伝搬を防止できないのは,このように対面する建造物が存在することによる建造物の反射屋外騒音(間接屋外騒音といってもよい)が,特に無方向的ともいうべく幅広の角度で屋外天井面に伝搬するとともに上記垂直の連結面が室内側に向けた再反射を行なって,むしろ屋外騒音の取り入れを行なう結果を招来するからである。   For example, condominiums along national roads, private apartments, etc. usually have buildings facing each other across the road and railway, but the noise of road and railway vehicles is high as in the lower floors. Although it propagates to the floors of the floor and is a problem for residents, vehicle noise propagates to higher floors like the lower floors as shown in Fig. 1. In this case, it is considered that the noise reaches the outdoor ceiling surface at a wide angle and is reflected from the outdoor ceiling surface to the indoor side. In this way, the reflected outdoor noise of the building due to the presence of the facing building (which may be referred to as indirect outdoor noise) propagates to the outdoor ceiling surface at a wide angle so as to be non-directional. The vertical connecting surface re-reflects toward the indoor side. It is, is because rather to lead to a result of performing the intake of outdoor noise.

本発明はかかる事情に鑑みてなされたもので,その解決課題とするところは,道路,鉄道を挟んだ対面する建造物によって反射して高層階に無方向的に到来する反射屋外騒音を簡易な構造で確実に室外側に再反射することによって室内側への伝搬を可及的高度に防止して,その遮音をなし得るようにしたマンション等建造物の反射屋外騒音再反射用天井パネルを提供するにあり,また該反射屋外騒音再反射用天井パネルを設置して反射屋外騒音の室外側への再反射による高層階の室内側への伝搬を可及的高度に防止して,その遮音をなし得るようにしたマンション等建造物を提供するにある。   The present invention has been made in view of such circumstances, and the problem to be solved is that reflected outdoor noise that is reflected by buildings facing each other across roads and railways and arrives non-directionally on higher floors is simplified. Providing ceiling panels for reflective outdoor noise re-reflection of buildings such as condominiums, etc., which can prevent the propagation to the indoor side as much as possible by reliably re-reflecting to the outside of the structure with the structure. In addition, the ceiling panel for reflection outdoor noise re-reflection is installed to prevent the reflection outdoor noise from re-reflecting to the outside of the room to the highest possible level and prevent the sound insulation. It is to provide buildings such as condominiums that can be made available.

A sound wave reflecting ceiling panel is formed in the depth direction of the ceiling surface and the height is 3 to 3 to 15 cm, and the reflected outdoor noise is always re-reflected toward the outdoor side in the sound wave reflecting inclined surface. Therefore, it is possible to prevent the reflected outdoor noise of the facing building that has reached the outdoor ceiling surface of the higher floor from re-reflecting to the outside of the room and to enter the room, and to achieve normal sound insulation at the highest possible altitude. In other words, the invention according to claim 1 is applied to roads along national roads, along private railways, etc. Project outside Installed on the exposed outdoor ceiling surface, and reflected outdoor noise caused by roads or railway vehicles that arrive non-directionally on the high floor due to reflection of the building facing it, re-reflects to the outside of the room and enters the room on the high floor.

In addition to reducing the reflected outdoor noise that reaches the inside, the possibility of re-reflection of the reflected outdoor noise that has reached between the sound wave reflection inclined surfaces to the indoor side is prevented as much as possible. In order to further prevent propagation toward the outside and make it possible to effectively and reliably perform the sound insulation of the reflected outdoor noise, the inclined surface inclined downward toward the outdoor side of the sound wave reflecting inclined surface is arranged. 2.

請求項2に記載の発明は,同じく上記に加えて,上記音波反射傾斜面の幅を室内外異幅,特に室外側に向けて下降傾斜する傾斜面を幅広とすることによって該音波反射傾斜面内に至る上記反射屋外騒音を減少するとともに該音波反射傾斜面間に至った反射屋外騒音の室内側への再反射の可能性を可及的確実に防止して,反射屋外騒音の室内側に向けた伝搬を更に高度に防止して,反射屋外騒音の遮音を極めて有効且つ確実になし得るものとすることができる。   In addition to the above, the invention according to claim 2 is characterized in that the sound wave reflection inclined surface is made wider by making the width of the sound wave reflection inclined surface different from the outside of the room, particularly the inclined surface that is inclined downward toward the outdoor side.

It is possible to prevent the reflected outdoor noise to a higher degree and to perform the insulation of the reflected outdoor noise extremely effectively and reliably.

請求項3に記載の発明は,同じく上記に加えて,上記反射屋外騒音再反射用天井パネルを設置して対面する建造物の反射屋外騒音の室外側への再反射によって室内側への伝搬を可及的高度に防止して,その遮音をなし得るようにした反射屋外騒音再反射用天井パネル設置のマンション等建造物を提供することができる。   In addition to the above, the invention described in claim 3 is the above-described reflection outdoor noise re-reflection ceiling panel, and the reflected outdoor noise of the building facing the building is propagated to the indoor side by re-reflection to the outdoor side. It is possible to provide a building such as a condominium with a reflective outdoor noise re-reflection ceiling panel that can prevent the noise as much as possible and achieve sound insulation.

以下図面の例に従って本発明を更に具体的に説明すれば,Aはマンション等建造物であり,該建造物Aは,反射屋外騒音再反射用天井パネル10を,国道沿い,私鉄沿い等の道路,鉄道を挟んだ対面する建造物存在のマンション等建造物における高層階のベランダスラブ,庇等の室外側に突出乃至露出した屋外天井面,本例にあってはベランダスラブの屋外天井面Bに設置して,上記対面する建造物の反射による無方向的な反射屋外騒音を音波反射傾斜面内で室外側に再反射して高層階の室内に至るのを防止してあり,このとき反射屋外騒音再反射用天井パネル10は,室内側及び室外側に向けて下降傾斜した内角を直角又は略直角としたとした音波反射傾斜面11を内外交互に配置することによって下向き開口多数の音波反射傾斜面11を上記屋外天井面Bの奥行方向に連続配置して形成し,上記無方向的な反射屋外騒音を該反射傾斜面11内で室外側に再反射自在とした上下高さを3乃至15cmとしたものとしてある。 Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a building such as a condominium, and the building A includes a reflective outdoor noise re-reflection ceiling panel 10 along a national road, a private railway road, etc. , A high-rise veranda slab in a condominium or other building that faces the railway, an outdoor ceiling surface protruding or exposed to the outside of a fence, etc., in this example, an outdoor ceiling surface B of the veranda slab It is installed to prevent the non-directional reflected outdoor noise caused by the reflection of the building facing above from re-reflecting outside the sound wave reflection inclined surface to the indoors of the higher floors. The noise re-reflective ceiling panel 10 has a plurality of sound wave reflecting slopes with downward openings by alternately arranging sound wave reflecting inclined surfaces 11 whose inner angles descending toward the indoor side and the outdoor side are right angles or substantially right angles. Surface 11 The outdoor ceiling surface B is formed by being continuously arranged in the depth direction, and the vertical height is set to 3 to 15 cm so that the non-directional reflected outdoor noise can be re-reflected to the outdoor side in the reflective inclined surface 11. It is as.

反射屋外騒音再反射用天井パネル10は,例えばアルミ,ステンレス等の金属,ポリカーボネート,塩化ビニール等の合成樹脂等の音波反射性を有する硬質材によって,屋外天井面Bの奥行方向に一体に形成したもの,該奥行方向に複数乃至多数のパネル要素を連結したものを用いることによって該奥行方向に拡開対向傾斜面11を一連に連続配置したものとしてあり,例えば硬質材による板材を折曲加工し,また押出加工することによって一体に形成し,単一の傾斜面をなすパネル要素を隣接相互に溶着,嵌合等の固定手段によって固定し,また,例えば単一乃至複数の拡開対向傾斜面11をなすように室内外に向けて下降傾斜した一対乃至複数対のパネル要素を隣接相互に同様に固定手段によって固定して,奥行方向に連結したものとしてある。   The reflective outdoor noise re-reflection ceiling panel 10 is integrally formed in the depth direction of the outdoor ceiling surface B by a hard material having sound wave reflectivity such as metal such as aluminum and stainless steel, synthetic resin such as polycarbonate and vinyl chloride. A plurality of panel elements connected in the depth direction are used to continuously arrange the expansion facing inclined surfaces 11 in the depth direction. For example, a plate material made of a hard material is bent. In addition, panel elements that are integrally formed by extrusion and have a single inclined surface are fixed to each other by fixing means such as welding and fitting to each other, and, for example, a single or a plurality of widening facing inclined surfaces 11 and a pair of panel elements inclined downward toward the inside and outside of the room are fixed to each other by fixing means in the same manner and connected in the depth direction. A.

反射屋外騒音再反射用天井パネル10は,その音波反射傾斜面11が上記室内側に向けて下降傾斜した傾斜面12と室外側に向けて下降傾斜した傾斜面13を上記連続配置することによって内角を直角又は略直角,即ち音波反射傾斜面11の頂角を通る垂直線に対して同一対称角度の対向2面によって下向き拡開V字状をなすものとしてあり,これによって屋外天井面B奥行方向の各音波反射傾斜面11がこれに至った反射屋外騒音を可及的に室外側に再反射するようにしてある。   The reflected outdoor noise re-reflection ceiling panel 10 has an inner angle by continuously arranging the inclined surface 12 whose sound wave reflecting inclined surface 11 is inclined downward toward the indoor side and the inclined surface 13 inclined downward toward the outdoor side. Is formed into a V-shaped downward expansion by two opposing surfaces having the same symmetry angle with respect to a vertical line passing through the vertical angle of the sound wave reflection inclined surface 11, and thereby the depth direction of the outdoor ceiling surface B Each of the sound wave reflecting inclined surfaces 11 re-reflects the reflected outdoor noise reaching the outside as much as possible to the outdoor side.

即ち反射屋外騒音は,音源から対面する建造物に反射した反射騒音であり,その屋外天井面Bに至る角度は無方向的というべく幅広のものとなるために音波反射傾斜面11,特に室外側に向けて下降傾斜する傾斜面13に対する屋外騒音の入射角度は多様であり,該音波反射傾斜面11に至った屋外騒音は,その入射角度と同一角度で反射することによって,図5のように室内側に向けて下降傾斜した傾斜面12に当たって直接に室外側に反射されるか,図6のように室内側に向けて下降傾斜した傾斜面12に当った後に更に室外側に向けて下降傾斜した傾斜面13に向けて反射し,該傾斜面13から室外側に再反射されるようにして,これが室内側に反射されるのを阻止して,その可及的高度にして常時の遮音をなし得るようにしてある。   That is, the reflected outdoor noise is reflected noise reflected from the sound source to the building facing the sound source, and since the angle to the outdoor ceiling surface B is non-directional and wide, the sound wave reflecting inclined surface 11, particularly the outdoor side. There are various incident angles of outdoor noise on the inclined surface 13 inclined downward toward the surface, and the outdoor noise reaching the sound wave reflecting inclined surface 11 is reflected at the same angle as the incident angle, as shown in FIG. Reflected directly to the outdoor side by hitting the inclined surface 12 inclined downward toward the indoor side, or further inclined downward toward the outdoor side after hitting the inclined surface 12 inclined downward toward the indoor side as shown in FIG. The reflected light is reflected toward the inclined surface 13 and re-reflected from the inclined surface 13 to the outside of the room. You can get none.

本例にあって該音波反射傾斜面11は,その拡開角度,即ちそのV字状の下向き開口の頂角の内角を上記直角又は略直角をなすものとしてあり,これによって反射角度が入射角度と同一角度であることから,水平方向乃至直交方向のいずれの場合の騒音に対しても音波反射傾斜面11が上記室外側に向けた直接の反射を行なうか,音波反射傾斜面11間の反射を経て室外側に向けた再反射を行なうようにしてあり,マンション等の建造物に対する騒音は,上層階で傾斜方向の反射騒音となるところ,上記水平方向乃至直交方向の範囲で反射屋外騒音を室外側に向けて反射することによって,高層階の屋外天井面Bを介して室内側に伝搬する屋外騒音を更に有効且つ確実に防止し,その好ましい遮音を行うことができるようにしてある。   In this example, the sound wave reflecting inclined surface 11 has an expansion angle, that is, an inner angle of the apex angle of the V-shaped downward opening, which is the above right angle or a substantially right angle. Therefore, the sound wave reflection inclined surface 11 performs direct reflection toward the outdoor side or the reflection between the sound wave reflection inclined surfaces 11 with respect to noise in any of the horizontal direction and the orthogonal direction. The re-reflection toward the outside of the room is conducted through the building, and the noise to buildings such as condominiums becomes the reflected noise in the inclination direction on the upper floor. By reflecting toward the outdoor side, the outdoor noise propagating to the indoor side through the outdoor ceiling surface B of the higher floor is further effectively and reliably prevented, and the preferable sound insulation can be performed.

内角を直角又は略直角とすることによって音波反射用パネル10の室内側及び室外側に向けて下降傾斜する傾斜面12,13は45°又は略45°と角度となり,音波反射用天井パネル10は,屋外天井面Bとの間で連続する直角2等辺三角形を形成するように音波反射傾斜面11を配置したものとなるから,該内角を直角又は略直角としてあり,これによって上記直接の反射と再反射の確実性をより向上することができる。 By setting the inner angle to a right angle or a substantially right angle, the inclined surfaces 12 and 13 that incline downward toward the indoor side and the outdoor side of the sound wave reflection panel 10 have an angle of 45 ° or substantially 45 °. The sound wave reflecting inclined surface 11 is arranged so as to form a continuous right angled isosceles triangle with the outdoor ceiling surface B. Therefore, the inner angle is set to be a right angle or a substantially right angle. The certainty of re-reflection can be further improved.

音波反射用天井パネル10の形成に際して,その屋外天井面Bに対する,例えばアンカー固定部位をなすように,またパネル要素の連結を行う場合にその連結部位をなすように,音波反射傾斜面11の頂角部分を裁頭し又は該頂角部分を塞ぐ如くに屋外天井面Bの幅方向に帯状をなす帯幅部分を,全て又は一部の拡開対向傾斜面11の上端に配置することが可能であるが,この場合もその延長線による頂角が直角又は略直角となるように音波反射傾斜面11の内角を設定するものとしてある。帯幅部分を広く形成すれば垂直方向等一部の反射屋外騒音が室内側に向う可能性が残るが,この種の屋外騒音は少ないので実用上然程の影響は生じないので,該帯幅部分が幅広となることによって実用上の影響が生じるものを除いて,上記固定や連結のために比較的幅狭の帯幅部分を,音波反射傾斜面11の上端に配置することを妨げない。   When the sound wave reflecting ceiling panel 10 is formed, the top of the sound wave reflecting inclined surface 11 is formed so as to form, for example, an anchor fixing portion with respect to the outdoor ceiling surface B, or to form a connecting portion when connecting panel elements. It is possible to arrange the band width part which forms a band shape in the width direction of the outdoor ceiling surface B so as to cut off the corner part or close the apex part at the upper end of all or part of the widening facing inclined surface 11 However, also in this case, the inner angle of the sound wave reflection inclined surface 11 is set so that the apex angle by the extension line becomes a right angle or a substantially right angle. If the band width part is made wide, there is a possibility that some reflected outdoor noises such as the vertical direction will be directed to the indoor side. However, since this kind of outdoor noise is small, there will be no practical effect. Except for the case where a practical effect is caused by the widened portion, it is not obstructed to dispose a relatively narrow band width portion at the upper end of the sound wave reflecting inclined surface 11 for the fixing and connection.

音波反射用天井パネル10は,屋外天井面Bの奥行方向にその高さを,上記例の如くに同一とすることができるが,更に該高さを連続的又は断続的に高くすることによって奥行方向に高く形成する異高のものとすることができる。また拡開対向傾斜面11は屋外天井面Bの奥行方向にその拡開角度を同一とすることが好ましい。一般に音波反射用天井パネル10の上下高さは,これを上記3乃至15cmのものとすればよいが,遮音性を確保するとともに屋外天井面Bが低くなるのを防止し且つ設置外観を確保する上では,5乃至10cmとするのが好ましい。   The acoustic reflection ceiling panel 10 can have the same height in the depth direction of the outdoor ceiling surface B as in the above example, but the depth can be increased by increasing the height continuously or intermittently. Different heights can be formed to be higher in the direction. Moreover, it is preferable that the expansion facing inclined surface 11 has the same expansion angle in the depth direction of the outdoor ceiling surface B. In general, the height of the ceiling panel 10 for sound wave reflection should be 3 to 15 cm, but the sound insulation is ensured, the outdoor ceiling surface B is prevented from being lowered, and the installation appearance is secured. Above, it is preferably 5 to 10 cm.

図7,8は,他の例を示すもので,本例にあって音波反射用天井パネル10は,その上記音波反射傾斜面の11室外側に向けて下降傾斜した傾斜面13を,室内側に向けて下降傾斜した傾斜面12より幅広長寸化して該音波反射傾斜面11の室外側に向けて傾斜突出する突出傾斜面14を追加的に配置したものとしてある。   FIGS. 7 and 8 show other examples. In this example, the sound wave reflecting ceiling panel 10 has an inclined surface 13 inclined downward toward the outside of the room 11 of the sound wave reflecting inclined surface. A protruding inclined surface 14 that is wider and longer than the inclined surface 12 that is inclined downward toward the outside and protrudes toward the outdoor side of the sound wave reflecting inclined surface 11 is additionally disposed.

本例の音波反射用天井パネル10は,上記例のもの,例えば音波反射傾斜面11の拡開角度を直角としたものの該音波反射傾斜面11におけるその室外側に向けて下降傾斜した傾斜面12を,例えば該傾斜面12の2倍程度に幅広長寸化して該拡開対向傾斜面11の幅を室内外異幅のものとしてあり,その突出傾斜面14によって反射屋外騒音の再反射を促進して音波反射傾斜面11内に至る屋外騒音を減少するとともに該音波反射傾斜面11間に至った反射屋外騒音の室外側への再反射の可能性を可及的確実に防止したものとしてある。該室外側に向けて下降傾斜する傾斜面13の幅広長寸化は,屋外天井面Bの奥行方向にその一部,例えば1つ乃至2つ置きに行なうようにすることも可能であるが,本例にあってはその全部について幅広長寸化を施したものとして,該反射の促進と室外側への再反射の可能性を可及的高度のものとし,また上記突出傾斜面14が室外側に向いた面をなすことによって室内側からの外観を良好なものとするようにしてある。   The ceiling panel 10 for sound wave reflection of this example is the same as that of the above example, for example, the inclined surface 12 inclined downward toward the outdoor side of the sound wave reflection inclined surface 11 although the expansion angle of the sound wave reflection inclined surface 11 is a right angle. For example, the width of the widening facing inclined surface 11 is made different from the indoor and outdoor widths by about twice as wide as the inclined surface 12, and the projecting inclined surface 14 promotes re-reflection of reflected outdoor noise. Thus, the outdoor noise reaching the sound wave reflecting inclined surface 11 is reduced, and the possibility of re-reflection of the reflected outdoor noise reaching the sound wave reflecting inclined surface 11 to the outdoor side is prevented as much as possible. . Although it is possible to increase the width and length of the inclined surface 13 that is inclined downward toward the outdoor side, a part, for example, every other one or two in the depth direction of the outdoor ceiling surface B, In this example, it is assumed that all of them are widened and elongated, and the possibility of the promotion of the reflection and the re-reflection to the outside of the room is made as high as possible. By forming a surface facing outward, the appearance from the indoor side is improved.
