As a specific material of the core material 30, for example, inorganic artificial fibers such as rock wool produced by mixing lime or the like with glassy iron furnace slag obtained by an iron making process and melting at high temperature are preferably used. It is done. The core member 30 is bonded to the metal plate 20 with an adhesive such as urethane resin. The overall dimensions of the wall panel 10 are, for example, a width of about 900 mm and a height of about 1800 to 12000 mm, and the thickness depends on the thickness of the metal plate 20 and the core material 30. And about 100-150 mm is preferable from a viewpoint of workability.

［３］壁パネルの接合
壁パネル１０は、立てた状態で上下方向に延びる長手方向に沿った側端面どうしが接合され、これによりパネル接合壁１０Ａが構成される。図３に示すように、壁パネル１０の一方（図３で右側）の側端面には表裏の金属板２０が折り返されることにより凹部１１が形成され、凹部１１の底面に長手方向に沿った凸条３１が形成されている。また、壁パネル１０の他方（図２で左側）の側端面には厚さを減じることで凸部１２が形成され、凸部１２の端面に長手方向に沿った溝３２が形成されている。壁パネル１０の両方の側端面は芯材３０が露出しており、その芯材３０の厚さ方向中央部に、凸条３１および溝３２が形成されている。 [3] Joining of Wall Panels In the wall panel 10, the side end faces along the longitudinal direction extending in the up-down direction are joined in an upright state, thereby forming the panel joining wall 10 </ b> A. As shown in FIG. 3, a concave portion 11 is formed on one side end surface (right side in FIG. 3) of the wall panel 10 by folding the front and back metal plates 20, and the bottom surface of the concave portion 11 is projected along the longitudinal direction. Article 31 is formed. Further, the convex portion 12 is formed by reducing the thickness on the other side end surface (left side in FIG. 2) of the wall panel 10, and the groove 32 along the longitudinal direction is formed on the end surface of the convex portion 12. The core material 30 is exposed on both side end surfaces of the wall panel 10, and a ridge 31 and a groove 32 are formed in the central portion of the core material 30 in the thickness direction.

壁パネル１０は、充填材５１を間に挟んで圧縮させ、凹部１１と凸部１２を互いに嵌合させるとともに凸条３１に溝３２を嵌合させて接合される。充填材５１は、例えば厚さ１０〜１５ｍｍ程度のセラミックファイバーや生体溶解性繊維等が用いられる。   The wall panel 10 is compressed with the filler 51 interposed therebetween, and the concave portion 11 and the convex portion 12 are fitted to each other and the groove 32 is fitted to the convex strip 31 and joined. As the filler 51, for example, a ceramic fiber or a biosoluble fiber having a thickness of about 10 to 15 mm is used.

上記のようにして複数の壁パネル１０を横方向に接合してパネル接合壁１０Ａが構成され、パネル接合壁１０Ａを空気層４０を隔てて平行に対面させ、本実施形態の二重壁構造の遮音パネルが構成される。   As described above, a plurality of wall panels 10 are joined in the lateral direction to form a panel joining wall 10A, and the panel joining wall 10A is faced in parallel with the air layer 40 interposed therebetween. A sound insulation panel is constructed.

［４］壁パネルの固定
図４は、アングル５を用いた床スラブ１および上階スラブ２への壁パネル１０の固定構造を示している。床スラブ１と上階スラブ２間に壁パネル１０を立設する際には、壁パネル１０と床スラブ１との間、および壁パネル１０と上階スラブ２との間に充填材５２を介在させる。充填材５２は、上記充填材５１と同様のものが用いられる。アングル５は、亜鉛メッキ鋼板等からなる板材を加工した断面Ｌ字状のもので、厚さが例えば２．３〜３．２ｍｍ程度であって必要な剛性を有している。アングル５の長さは、複数の壁パネル１０間にわたる長さを有している。 [4] Fixing of Wall Panel FIG. 4 shows a fixing structure of the wall panel 10 to the floor slab 1 and the upper floor slab 2 using the angle 5. When the wall panel 10 is erected between the floor slab 1 and the upper floor slab 2, the filler 52 is interposed between the wall panel 10 and the floor slab 1 and between the wall panel 10 and the upper floor slab 2. Let The filler 52 is the same as the filler 51 described above. The angle 5 has an L-shaped cross section obtained by processing a plate material made of a galvanized steel plate or the like, and has a thickness of about 2.3 to 3.2 mm, for example, and has a necessary rigidity. The length of the angle 5 has a length extending between the plurality of wall panels 10.

アングル５は壁パネル１０を挟む一対の状態で床スラブ１および上階スラブ２にスラブ留付材６で固定され、壁パネル１０にはパネル留付材７で固定される。アングル５の固定点、すなわちスラブ留付材６およびパネル留付材７による固定箇所は、それぞれ所定間隔をおいて概ね等間隔になるように設定される。   The angle 5 is fixed to the floor slab 1 and the upper floor slab 2 with a slab fastening material 6 in a pair of states sandwiching the wall panel 10, and is fixed to the wall panel 10 with a panel fastening material 7. The fixing points of the angle 5, that is, the fixing points by the slab fastening material 6 and the panel fastening material 7 are set so as to be approximately equidistant from each other with a predetermined interval.

壁パネル１０は、所定の間隔（上記５０〜３００ｍｍの範囲）をあけて平行に対面する状態に固定される。固定にあたっては、図１に示すように、壁パネル１０の目地が対面する壁パネル１０の目地に対し横方向にずれて目地が千鳥状に互い違いとなるように、例えば左端から右に向かって、奥側と手前側の壁パネル１０を１枚ずつ順に固定していく。そのため、いずれか一方側（図１では手前側）のパネル接合壁Ａの端部の壁パネル１０は幅が小さいものを用いる。これにより、対面する壁パネル１０の間の内側に配されるアングル５を床スラブ１、上階スラブ２および壁パネル１０に固定することができる。   The wall panel 10 is fixed in a state of facing in parallel with a predetermined interval (in the range of 50 to 300 mm). In fixing, as shown in FIG. 1, for example, from the left end to the right so that the joints of the wall panel 10 are laterally shifted with respect to the joints of the wall panel 10 facing each other and the joints are staggered, for example, The wall panels 10 on the back side and the near side are fixed one by one in order. Therefore, the wall panel 10 at the end of the panel joint wall A on either side (the front side in FIG. 1) has a small width. Thereby, the angle 5 distribute | arranged inside the wall panel 10 which opposes can be fixed to the floor slab 1, the upper floor slab 2, and the wall panel 10. FIG.

対面する各壁パネル１０は、それぞれ床スラブ１および上階スラブ２に対しアングル５によって独立して固定されており、壁パネル１０どうしを連結する部材は何もなく、壁パネル１０どうしは非連結状態となっている。なお、スラブ留付材６はコンクリートアンカーボルト、コンクリートねじ、ドリリングタッピングねじ、ドリルねじ等が用いられ、パネル留付材７はドリリングタッピングねじやドリルねじ等が用いられる。   Each facing wall panel 10 is independently fixed to the floor slab 1 and the upper floor slab 2 by an angle 5, there is no member for connecting the wall panels 10, and the wall panels 10 are not connected to each other. It is in a state. The slab fastening material 6 is a concrete anchor bolt, a concrete screw, a drilling tapping screw, a drill screw or the like, and the panel fastening material 7 is a drilling tapping screw or a drill screw.

［５］本実施形態の作用効果
上記本実施形態によれば、金属サンドイッチパネルからなる壁パネル１０を接合したパネル接合壁１０Ａを二重に設けた構成により、高い遮音性を有する遮音壁を構築することができる。本実施形態では、二重のパネル接合壁１０Ａのそれぞれの目地が、互いに横方向にずれており、千鳥状に互い違いとなっているため、空気層４０側、すなわち内側のアングル５を床スラブ１、上階スラブ２および壁パネル１０に固定することができる。また、目地がずれていることにより遮音性の向上が図られる。 [5] Effects of the present embodiment According to the present embodiment, a sound insulating wall having high sound insulating properties is constructed by providing a double panel bonding wall 10A obtained by bonding the wall panel 10 made of a metal sandwich panel. be able to. In the present embodiment, the joints of the double panel joint walls 10A are laterally displaced from each other and are staggered, so that the angle 5 on the air layer 40 side, that is, the inner side, is set to the floor slab 1. The upper floor slab 2 and the wall panel 10 can be fixed. In addition, the sound insulation is improved by shifting the joint.

また、対面する各壁パネル１０はそれぞれ床スラブ１および上階スラブ２に対しアングル５によって独立して固定され壁パネル１０どうしは非連結状態となっており、壁パネル１０間には空気層４０が存在するのみであり、これによっても遮音効果を高めることができる。   Each facing wall panel 10 is fixed independently to the floor slab 1 and the upper floor slab 2 by an angle 5 so that the wall panels 10 are not connected to each other, and an air layer 40 is provided between the wall panels 10. This also increases the sound insulation effect.

上記実施形態では二重のパネル接合壁１０Ａの厚さは同じとしているが、図２（ｂ）に示すように異なる厚さの壁パネル１０を用い、一方側と他方側のパネル接合壁１０Ａの厚さが異なっている構成としてもよい。また、二重構造は本発明の一例であり、三重、四重といった多重壁の構造も本発明は含む。   In the above embodiment, the thickness of the double panel joining wall 10A is the same. However, as shown in FIG. 2B, the wall panels 10 having different thicknesses are used, and the panel joining walls 10A on one side and the other side are used. It is good also as a structure from which thickness differs. Further, the double structure is an example of the present invention, and the present invention includes a multiple wall structure such as triple or quadruple.

（実施例１）
複数の壁パネルを接合した第１のパネル接合壁と、複数の壁パネルを接合した第２のパネル接合壁とが平行な二重壁構造の遮音壁を、第１、第２のパネル接合壁間の間隔を９０ｍｍに設定して構築した。第１のパネル接合壁側の壁パネルは、厚さが１．０ｍｍの２枚の塗装鋼板の間に密度が１５０ｋｇ／ｍ３以上のロックウールを挟んで接着させたパネル全体の厚さが１５０ｍｍの金属サンドイッチパネルであり、第２のパネル接合壁側の壁パネルは、全体厚さが１００ｍｍである点以外は第１のパネル接合壁側の壁パネルと同一構成である。また、壁パネルどうしの接合構造は図３で示した構造と同一である。 Example 1
A sound insulation wall having a double wall structure in which a first panel joint wall obtained by joining a plurality of wall panels and a second panel joint wall obtained by joining a plurality of wall panels is parallel to the first and second panel joint walls. The interval was set to 90 mm. The wall panel on the first panel joining wall side has a total panel thickness of 150 mm, in which rock wool having a density of 150 kg / m 3 or more is sandwiched between two coated steel sheets having a thickness of 1.0 mm. The wall panel on the second panel joint wall side has the same configuration as the wall panel on the first panel joint wall side except that the overall thickness is 100 mm. Further, the joint structure between the wall panels is the same as the structure shown in FIG.

（実施例２）
第１のパネル接合壁側の壁パネルの塗装鋼板の厚さが０．５ｍｍでパネル全体の厚さが１００ｍｍである点以外は実施例１と同様として、二重壁構造の遮音壁を構築した。 (Example 2)
A sound insulation wall having a double wall structure was constructed in the same manner as in Example 1 except that the thickness of the coated steel plate of the wall panel on the first panel joining wall side was 0.5 mm and the thickness of the entire panel was 100 mm.

（比較例１）
塗装鋼板の厚さが０．５ｍｍでパネル全体の厚さが１００ｍｍの複数の壁パネルによる第１のパネル接合壁と、塗装鋼板の厚さが１．０ｍｍでパネル全体の厚さが１００ｍｍの複数の壁パネルによる第２のパネル接合壁とを、厚さ１２ｍｍの木製のスペーサを挟んで重ね合わせた構造の遮音壁を構築した。スペーサは分散配置し、対面する壁パネル間の間隔はスペーサの厚さすなわち１２ｍｍである。 (Comparative Example 1)
A first panel joining wall comprising a plurality of wall panels having a coated steel plate thickness of 0.5 mm and a total panel thickness of 100 mm; and a plurality of coated steel plates having a thickness of 1.0 mm and a total panel thickness of 100 mm A sound insulating wall having a structure in which the second panel joining wall of the wall panel is overlapped with a wooden spacer having a thickness of 12 mm is constructed. The spacers are distributed and the spacing between the facing wall panels is the spacer thickness, i.e. 12 mm.

（比較例２）
厚さが１．０ｍｍの２枚の塗装鋼板の間に密度が１５０ｋｇ／ｍ３以上のロックウールを挟んで接着させたパネル全体の厚さが１５０ｍｍの金属サンドイッチパネルからなる壁パネルを接合し、遮音壁を構築した。すなわち二重壁ではなく、壁パネル１枚の単板構成の遮音壁である。 (Comparative Example 2)
Joining a wall panel made of a metal sandwich panel with a total thickness of 150 mm bonded with rock wool having a density of 150 kg / m 3 or more between two coated steel plates with a thickness of 1.0 mm, A sound insulation wall was constructed. That is, it is not a double wall but a sound insulation wall having a single-panel construction with one wall panel.

（比較例３）
厚さが０．５ｍｍの２枚の塗装鋼板の間に密度が１５０ｋｇ／ｍ３以上のロックウールを挟んで接着させたパネル全体の厚さが１００ｍｍの金属サンドイッチパネルからなる壁パネルを接合し、遮音壁を構築した。すなわち実施例４と同様に単板構成の遮音壁である。 (Comparative Example 3)
Bonding a wall panel made of a metal sandwich panel with a total thickness of 100 mm, with a rock wool having a density of 150 kg / m 3 or more sandwiched between two coated steel plates with a thickness of 0.5 mm, A sound insulation wall was constructed. That is, it is a sound insulating wall having a single plate configuration as in the fourth embodiment.

上記実施例１、２および比較例１〜３の遮音壁につき、JIS A 1416（2000）「実験室における建築部材の空気音遮断性能の測定方法」にしたがって遮音性（透過損失）の評価を行った。その結果を図５に示す。   With respect to the sound insulation walls of Examples 1 and 2 and Comparative Examples 1 to 3, the sound insulation (transmission loss) was evaluated in accordance with JIS A 1416 (2000) “Method for measuring air sound insulation performance of building materials in a laboratory”. . The result is shown in FIG.

図５によれば、実施例１、２は比較例３〜５よりも遮音性が高く、特に１２５〜５００Ｈｚの低周波領域での遮音性が比較的優れていることが明らかである。比較例１はサンドイッチパネルを僅かな間隔（１２ｍｍ）をあけて対面させた二重壁構造であるが、スペーサが接触していることや間隔が狭いことから全体的には実施例よりも遮音性に劣り、特に１２５〜５００Ｈｚの低周波領域では本発明の二重壁構造の方が優位であることが確認された。   According to FIG. 5, it is clear that Examples 1 and 2 have higher sound insulation than Comparative Examples 3 to 5, and in particular, sound insulation in a low frequency region of 125 to 500 Hz is relatively excellent. Comparative Example 1 has a double-wall structure in which sandwich panels face each other with a slight gap (12 mm). However, since the spacers are in contact with each other and the gap is narrow, the overall sound insulation is better than that of the example. In particular, it was confirmed that the double wall structure of the present invention is superior in the low frequency region of 125 to 500 Hz.

本発明は、遮音性が求められる壁構造として利用され、特に１２５〜５００Ｈｚの低周波領域での遮音性が高く、例えば放送スタジオ等の間仕切りに好適である。   INDUSTRIAL APPLICABILITY The present invention is used as a wall structure that requires sound insulation, and particularly has high sound insulation in a low frequency region of 125 to 500 Hz, and is suitable for partitioning of a broadcast studio, for example.
