INTRATUBULAR PROPAGATION SOUND REDUCING STRUCTURE AND INTRATUBULAR PROPAGATION SOUND REDUCING ASSEMBLY
To provide an intratubular propagation sound reducing structure 2 that constitutes part of an intratubular propagation sound reducing structure and is excellent in processability and workability.SOLUTION: An intratubular propagation sound reducing structure 2 according to the present invention includes: a tubular outer peripheral wall 20 extending from an open first end 21 to a second end 22; a top plate 30 extending from the second end 22 toward a central axis D of the outer peripheral wall 20; a partition plate 33 provided between the top plate 30 and the first end 21 and extending from an inner surface 23 of the outer peripheral wall 20 toward the central axis D; and a sound absorbing material 40 arranged between the top plate 30 and the partition plate 33. The top plate 30 and the partition plate 33 are each open at the center. A first opening edge 31 of an opening of the top plate 30 and a second opening edge 34 of an opening of the partition plate 33 have the same shape, and are arranged opposite to each other in a direction along the central axis D. The sound absorbing material 40 is arranged so as to close a space between the first opening edge 31 and the second opening edge 34 and at an interval from the inner surface 23.SELECTED DRAWING: Figure 4
【課題】本発明は、管内伝搬音抑制構造の一部を構成しかつ加工性及び施工性に優れた管内伝搬音抑制構造体２を提供する。【解決手段】本発明に係る管内伝搬音抑制構造体２は、開口する第１端部２１から第２端部２２へ延びる筒状の外周壁２０と、第２端部２２から外周壁２０の中心軸Ｄに向かって延びる天板３０と、天板３０と第１端部２１との間に設けられ、外周壁２０の内面２３から中心軸Ｄに向かって延びる仕切り板３３と、天板３０と仕切り板３３との間に配置された吸音材４０と、を備える。天板３０及び仕切り板３３は、それぞれ中央で開口する。天板３０の開口の第１開口縁３１は、仕切り板３３の開口の第２開口縁３４と同じ形状を有し、かつ、中心軸Ｄに沿った方向で対向して配置される。吸音材４０は、第１開口縁３１と第２開口縁３４との間を塞ぎ、かつ、内面２３に対して間隔を空けて配置される。【選択図】図４
