Zusammenfassung:The present invention relates to a structure for reducing transmission of solid material sound, which can reduce solid material sound, generated from a hull, to a superstructure since a mount is installed between the hull and superstructure which form an ocean structure, and a support structure in an optimal shape for enabling support strength between the mount and the superstructure to be maintained at a maximum level. The structure for reducing transmission of solid material sound comprises: the superstructure (10); the hull (20) arranged under the superstructure; a plurality of mounts (30) which are arranged between the lower side of the superstructure and the upper side of the hull and reduce solid material sound generated by various kinds of equipment as noise sources in a ship; and the support structures (12) which are arranged on each corner of an inner lower portion of the superstructure (10) and reduce the transmission of solid material sound transmitted from the hull (20) by increasing support strength between the mount (30) and the superstructure (10). 본 발명은 해양 구조물을 이루는 선체와 거주구의 사이에 마운트를 설치하고, 이러한 마운트와 거주구간의 지지 강성이 최대한 유지 가능하도록 하는 최적 형상의 지지구조물을 구비하여 발생되는 선체로부터 발생되는 고체음이 거주구로의 전달을 저감시킬 수 있도록 한 것이다. 본 발명은 거주구(10)와; 상기 거주구(10)의 하부에 구비되는 선체(20)와; 상기 거주구(10)의 저면과 선체(20)의 상면 사이에 복수로 갖추어져서 선체내의 각종 소음원인 장비로부터 발생하는 고체음을 저감시키도록 하는 마운트(30)와; 거주구(10)의 내부 하부 각 모서리에 구비하여 마운트(30)와 거주구(10)간의 지지 강성이 증대되도록 함으로써, 상기 선체(20)로부터 전달되는 고체음의 전달양을 저감시키도록 하는 마운트 지지 구조물(12)을 포함하는 것이다.
