SOUND ABSORPTION APPARATUS
PROBLEM TO BE SOLVED: To provide a sound absorption apparatus capable of improving mounting strength of a front plate to a back plate.SOLUTION: A sound absorption apparatus configured to be installable on the rear surface side of an expressway comprises: a box-shaped frame 1; and a sound absorption member 2 provided in an internal space S of the frame 1. The frame 1 includes: a front plate 11 that is to be arranged on the upper side in the case of the frame being installed on the rear surface side of the expressway; and a back plate 12 that is to be arranged on the lower side in the case of the frame being installed on the rear surface side of the expressway. The front plate 11 includes: a body part 111 on which a plurality of apertures are formed; an end plate part 112 extending from an end of the body part 111 to the back plate 12 side; and a mounting plate part 113 extending from a tip of the end plate part 112 to the inside. The mounting plate part 113 is arranged outside the back plate 12 and is mounted on the back plate 12 using a blind rivet 14a.SELECTED DRAWING: Figure 7
【課題】背面板に対する前面板の取付強度の向上を図ることが可能な吸音装置を提供する。【解決手段】吸音装置は、高速道路の裏面側に設置可能に構成されており、箱状の筐体１と、筐体１の内部空間Ｓに設けられた吸音部材２とを備える。筐体１は、高速道路の裏面側に設置された場合に下側に配置される前面板１１と、高速道路の裏面側に設置された場合に上側に配置される背面板１２とを含む。前面板１１は、複数の開口が形成された本体部１１１と、本体部１１１の端部から背面板１２側に延びる端板部１１２と、端板部１１２の先端から内側に延びる取付板部１１３とを有する。取付板部１１３は、背面板１２に対して外側に配置され、ブラインドリベット１４ａにより背面板１２に取り付けられている。【選択図】図７
