To construct a sound insulation wall with high sound insulation by a wall panel with a sandwich structure in which a core material is sandwiched between two face materials.SOLUTION: Panel joining walls 10A each formed by joining a plurality of wall panels 10 sandwiched between two metal plates 20 with a core material 30 interposed therebetween are doubly placed with an air layer 40 interposed therebetween to construct a sound insulation wall. The distance between the facing wall panels 10 being the thickness of the air layer 40 is set to 50-300 mm, and a transmission loss for a sound with a frequency of 125 Hz is 30 dB or more.SELECTED DRAWING: Figure 2
【課題】２枚の面材の間に芯材が挟まれてなるサンドイッチ構造の壁パネルによって高い遮音性を有する遮音壁を構築する。【解決手段】２枚の金属板２０の間に芯材３０を挟んで接着した壁パネル１０を複数接合したパネル接合壁１０Ａを、間に空気層４０を挟んで二重に設置し、遮音壁を構築する。空気層４０の厚さである対面する壁パネル１０間の間隔を５０〜３００ｍｍに設定し、周波数が１２５Ｈｚの音に対する透過損失が３０ｄＢ以上である特性を有するものとする。【選択図】図２
