[0002] Floating floor is a kind of building floor sound insulation method, which uses vibration-damping pads to separate the floor and the rigid connection of the building structure.

[0003] The floating surface layer needs more professional design when used as a vibration reduction platform or vibration reduction floor to isolate the vibration of the machine. If the design is improper, the natural frequency of the vibration reduction system will be close to the vibration frequency of the machine, which will not only fail to reduce the vibration, but also increase the vibration and even damage the machine and floor structure. Floor impact sound insulation is one of the most difficult parts of sound insulation in a building. The method of using cast-in-place concrete on the glass wool vibration reduction pad can achieve an impact sound insulation effect of more than 20 to 30 dB. However, due to the small flat area of ​​the floor, there are often steps with height differences in the floating floor area, which destroys the integrity of the floating floor and causes the vibration reduction and sound insulation effect to fail.
