Study of the Influence of Ways of Connecting the Flexible Plate with a Spaceon Soundproofing of Enclosing Structures When Reconstructing Buildings
Examines the impact of ways of connecting the flexible plate with a space on the soundproofing of enclosing structures during reconstruction, overhaul andoperation of buildings with the use of layered vibro - damped elements in comparison with the sheets connected “dry”, with an air gap and filling it with soundinsulatingmaterial, with linear and point rigid and vibration - insulated fastening. In large reverberation rooms, experimental studies of the influence of methods of connection of layered vibro - damped elements or sheets connected «dry» on the sound insulation of the main enclosing structure of gypsum tongue - and - grooveplates or bricks were carried out. As flexible boards with a space, two gypsum or gypsum - fibre sheets, cement - strand or oriented strand slab of varying thicknessbonded by vibration - absorbing material Green Glu or Accent 117 or jointed «dry» were investigated. It is shown that when arranging the air gap between themain structure and the flexible plates with a space it is recommended to arrange linear vibro - damped connections, when filling the air gap with sound - absorbingmaterial - point vibration - insulated connections.
