FIT-TOGETHER WALL BODY HAVING IMPROVED SOUND ABSORBING AND SCREENING PERFORMANCE AND A FITTED-TOGETHER STRUCTURE COMPRISING THE SAME

摘要

The present invention relates to a fit-together wall body having improved sound absorbing and screening performance and to a fitted-together structure comprising the same, and the invention comprises: plate-shaped members formed spaced apart facing each other and constituting at least one layer each; stud members which are provided alternately against the different inside surfaces of each of the plate-shaped members and which are formed with a plurality of first punch holes to at least one diameter in a web part; an insulation member which is inserted interposed in the space constituted by each of the sheet-shaped members and the stud members; and sheet members which are formed placed in contact against the surfaces on the outsides of the insulation member, and are formed with a plurality of second punch holes to at least one diameter in the surface; and the invention can have an outstanding sound absorbing and sound screening performance in various frequency bands including low frequency bands without any additional increase in the thickness of the wall body.
