Rubber particle sound-insulation and vibration-damping cast-in-place floor construction method
The invention discloses a rubber particle sound-insulation and vibration-damping cast-in-place floor construction method. The rubber particle sound-insulation and vibration-damping cast-in-place floor construction method comprises the steps of cleaning the base layer of a floorslab, preparing rubber particle layer materials in the site, immediately paving a rubber particle sound-insulation and vibration-damping layer, maintaining the paved rubber particle sound-insulation and vibration-damping layer for 12-24 hours until the rubber particle sound-insulation and vibration-damping layer is solidified, and paving a decoration layer on the maintained pavement layer. The rubber particle sound-insulation and vibration-damping cast-in-place floor construction method is energy-saving, environment-friendly, and capable of improving the use ratio of renewable resources. The rubber particle layer not only is good in sound insulation performance but also has a moisture-proof function and an anti-condensation function. Decoration floorslab, especially wood floorslab is enabled to be kept dry. The common quality problem of deformation of the wood floorslab is solved. In addition, construction space is saved and construction cost is reduced compared with a constitutional type sound-insulation layer due to the fact that the rubber particle sound-insulation layer is adopted for construction.
