Abstract

The utility model discloses a sound insulation structure of a residential elevator hoistway, which comprises a first floor slab and a second floor slab, wherein the hoistway is fixedly arranged at the left ends of the first floor slab and the second floor slab together, a first vibration damping base plate is fixedly arranged at the lower end of the first floor slab, a first transverse keel is fixedly arranged at the lower end of the first vibration damping base plate, glass wool is fixedly arranged at the lower end of the first transverse keel, a gypsum board is fixedly arranged at the right end of the glass wool, and first sealant is fixedly arranged at the right part of the upper end of the gypsum board. By adopting the glass wool, the fibers in the glass wool are fluffy and staggered, a large number of tiny pores exist, and the sound absorption performance is good. The sound absorption principle is that a large number of tiny pores and holes which are communicated from inside to outside are formed in the sound absorption device, when sound waves are incident on the glass wool, the sound waves can enter the material through the pores, and the vibration of air molecules in the pores is caused. Due to the viscous drag of air and the friction of air molecules with the pore walls, acoustic energy is converted into heat energy and lost.
