The utility model discloses a sound absorption and vibration reduction
floating floor floor ground structure for a large-scale equipment room of a public building, which particularly relates to the field of
building construction and comprises a wall body, and a
noise reduction and vibration reduction mechanism is embedded in the wall body. The
noise reduction and shock absorption mechanism comprises a floor body, a concrete ground, a first waterproof layer, a floating building shock insulation
cushion layer, a shock absorption
cushion plate, a sound absorption plate, a second waterproof layer, a steel plate layer and sound insulation cotton. When the floor is used, the
noise reduction and shock absorption mechanism is arranged, the mute effect of the floor ground is improved, the first waterproof layer and the second waterproof layer effectively prevent water from permeating and damaging a lower-layer structure, the floating shock insulation
cushion layer can effectively isolate and absorb vibration and noise generated when equipment operates, and the service life of the floor is prolonged. The shock absorption cushion plate enhances the shock
absorption effect, it is ensured that
impact on the
floor slab is effectively relieved when equipment operates, the sound absorption plate and the sound insulation cotton can absorb and reduce the noise generated when the equipment operates, and the quiet degree of the internal environment of a building is improved.
