- W4320736884 abstract "Abstract The integrated composite wallboard is a new type of prefabricated building enclosure wallboard made of autoclaved aerated concrete (ALC) and rock wool panel, which can meet the thermal requirements of cold areas in China without additional insulation. The ALC of the integrated composite wallboard is divided into local four-sided supported plates by vertical and horizontal ribs, which makes the wallboard have a different sound insulation performance from the wallboard of single uniform material and the composite wallboard of double-layer lightweight plates. The authors investigate the sound insulation performance of the integrated composite wallboard and compare it with other lightweight wallboards. They have found an apparent coincidence frequency region of air-borne sound insulation, which coincides with the natural vibration frequency of the local four-sided supported panel of ALC. Such an anastomosis effect seriously affects the weighted sound reduction index Rw, which reduces the weighted sound reduction index by 6 ~ 8 dB. The sound insulation experiment of integrated composite wallboard of ALC and rock wool panel objectively reflects the adverse effects of the sandwiched wallboard structure and provides a reference for improving the sound insulation performance by structurally upgrading the integrated composite wallboard." @default.
