SOUND ARRESTER FOR ORANGE BUCKET
PROBLEM TO BE SOLVED: To provide a sound arrester for an orange bucket for reducing a discomfort noise generated by contact between a claw part of an orange bucket and foundation riprap and the like.SOLUTION: A sound arrester for an orange bucket that is fixed to be mounted to cover an orange bucket X while allowing the orange bucket to be freely opened and closed, comprises: a top face soundproof sheet for covering between an inner ring part and an outer ring part of a top face frame body 2; upper chain parts 4 of the same length whose one ends are attached to the outer ring part of the top face frame body 2 at the same intervals; an intermediate ring body 5 to which the other ends of the upper chain parts 4 are attached; a flexible lateral upper soundproof sheet 6 formed in a cylindrical shape between the outer ring part of the top face frame body 2 and the intermediate ring body 5; lower chain parts 7 of the same length whose one ends are attached to the intermediate ring body 5 at the same intervals; a lower ring body 8 to which the other ends of the lower chain parts 7 are attached; and a flexible lateral lower soundproof sheet 9 formed in a cylindrical shape between the intermediate ring body 5 and the lower ring body 8.
【課題】オレンジバケットの爪部と基礎捨石等との接触等によって発生する不快な騒音を低減させるオレンジバケット用の防音装置を提供する。【解決手段】オレンジバケットＸが開閉自在な状態でその全体を覆うように装着固定されるオレンジバケット用の防音装置を、上面枠体２の内輪部と外輪部との間を覆う上面防音シートと、一端が上面枠体２の外輪部に等間隔で取り付けられている同じ長さの上部チェーン部４と、上部チェーン部４の他端が取り付けられた中間環体５と、上面枠体２の外輪部と中間環体５との間で筒状に形成されている可撓性を有する側方上部防音シート６と、一端が中間環体５に等間隔で取り付けられている同じ長さの下部チェーン部７と、下部チェーン部７の他端が取り付けられた下方環体８と、中間環体５と下方環体８との間で筒状に形成されている可撓性を有する側方下部防音シート９とから構成させる。【選択図】図１
