SOUNDPROOF STRUCTURE AND SOUNDPROOF PANEL
To provide a soundproof structure and a soundproof panel, which achieve both structural rigidity and soundproof performance, which are applied by fastening a porous body to perforated plates.SOLUTION: A soundproof structure 10 and a soundproof panel comprise: core bodies 12 constituting a plurality of cells 14; a back plate 18 for covering opening faces of the respective cells in a thickness direction of the core bodies; perforated plates 20 which are arranged on an opposite side of the back plate via the core bodies in the thickness direction and in which through holes are formed; a porous body 24 which is brought into contact with the perforated plates in the thickness direction; and a fastening part 28 for fastening the porous body to a member except for the porous body. A ratio of an area in a range where the porous body is fastened to the perforated plates by the fastening part with respect to a contact area with the perforated plates in the porous body is 92% or less.SELECTED DRAWING: Figure 1
【課題】多孔質体を有孔板に留めておくことで付与される構造上の剛性、及び防音性能を両立することが可能な防音構造体及び防音パネルを提供する。【解決手段】本発明の防音構造体１０及び防音パネルは、複数のセル１４を構成するコア体１２と、コア体の厚み方向において各セルの開口面を覆う背面板１８と、厚み方向においてコア体を介して背面板とは反対側に配置され、且つ、貫通孔が形成された有孔板２０と、厚み方向において有孔板に接触している多孔質体２４と、多孔質体を多孔質体以外の部材に留める留め部２８とを有する。多孔質体における有孔板との接触面積に対する、多孔質体が留め部によって有孔板に留められている範囲の面積の比率が９２％以下である。【選択図】図１
