JPS6478298A - Soundproof box - Google Patents

Abstract

PURPOSE: To obtain sufficiently enough soundproof performance, to obtain lightweight and compact structure to be easily handled and to make it possible to decompose the box to small pieces at the time of carrying it by forming a frame body to be a skeleton member by pipe materials to be optionally decomposed and assembled and forming a soundproof body like sheets consisting of laminating a sound absorbing layer, a sound shielding layer and an external sheet layer. CONSTITUTION: The frame body to be the skeleton member is formed by pipe materials to be optionally decomposed/assembled and a structure body 2 constituted of detachably attaching a suction hood body 11 to one of both the opposite side faces of the frame body and detachably attaching an exhaust hood to the other side face is covered with the sheet-like soundproof body consisting of laminating the sound absorbing layer 30, the sound shielding layer 31 and the external sheet layer 32. Consequently sufficiently enough soundproof performance can be obtained, the driving environment of stored engine equipment and materials can be maintained always at an effective state, the lightweight and compact structure can easily be handled, and at the time of storing/carrying the soundproof box, the box can be decomposed/folded to small pieces to be easily handled.
