SOUND-INSULATING WALL
PROBLEM TO BE SOLVED: To provide a transparent and highly fireproof sound-insulating wall, to be installed along a side edge of a vehicle passageway.SOLUTION: A sound-insulating wall 10 includes a transparent plate 20, and a support frame 30 supporting outer periphery of the transparent plate 20. The transparent plate 20 comprises one or more layers of glass sheets 21, 22, and measures 4 mm or more in thickness. The transparent glass plate 20 contains chemically strengthened glass, and has a compressive stress layer formed on the chemically strengthened glass surface with a depth measuring 12 μm or more. In the case where the transparent plate 20 is a glass laminate, one or more of the plurality of glass sheets 21, 22 needs to be chemically strengthened glass, for suppressing penetration by a flame through the transparent plate 20 and a collapse of the transparent plate 20 at a time of fire.SELECTED DRAWING: Figure 1
【課題】車両の通路の側縁に沿って配置される、透明で耐火性に優れた、遮音壁を提供する。【解決手段】遮音壁１０は、透明板２０と透明板２０の外周を支持する支持枠３０よりなる。透明板２０は、少なくとも一層以上のガラス板２１，２２よりなり、４ｍｍ以上の厚さを有している。さらに透明板２０は化学強化ガラスを含み、化学強化ガラスの表面に形成される圧縮応力層の深さを１２μｍよりも大きく形成してある。透明板２０が合わせガラスの場合、複数のガラス板２１、２２のうちの少なくとも１枚が、化学強化ガラスであればよく、火災の炎による透明板２０の貫通および透明板２０の崩落が抑制できる。【選択図】図１
