The elevator itself for sound insulation and vibration reduction treatment, to reduce or eliminate the purpose of noise, this is a method to deal with the source. For example, the elevator track in the well is reformed, and soundproof felt is installed as vibration cushion; Or install a guide rail vibration and noise reduction device to reduce the structural sound transmission in the well. This requires the transformation of the elevator already in use, not only need to remove the elevator related components, the construction process is more complicated.

Sound insulation walls can also be installed between the elevator shaft and the room. This practice is listed in the atlas "Sound Insulation and Sound Absorption Construction of Buildings" (08J931). This practice has little impact on the elevator shaft space, but also on the elevator operation without any obstruction, safety is good, but the construction process is complex, has a certain impact on the size of the room space, especially for the current inch of room an inch of gold, is not considered by real estate developers.

In addition, is the elevator shaft wall for sound insulation treatment, such as in the well to increase environmental protection polyester fiber sound insulation cotton, gradient sound absorbing cotton and other healthy and efficient sound insulation materials. At present, the conventional practice is to paste sound insulation materials (such as PANHOO cotton) on the inner wall of the well, and then take external protective measures.

There is one way: the wall base of the elevator shaft wall +PANHOO environmental protection sound insulation cotton (pinned to the wooden keel of 4cm╳ cm every 60cm along the height of the wall) + steel wire mesh nailed to the wooden keel + cement mortar plaster. This practice has a certain effect of sound absorption and sound insulation, but there are some problems in the construction, especially for the practice of laying sound insulation cotton, because in the sound insulation cotton, wire mesh outside cement mortar, cement mortar adhesion is poor, easy to crack, fall off, durability is not good.

The second method is as follows: the elevator shaft wall wall base + nail 2mm high barrier sound felt + nail wire mesh layer +2cm thick cement mortar plaster. This approach is better than the first approach, because the cement mortar can be better bonded on the wire mesh. However, when the size of the elevator shaft is limited, environment-friendly and efficient PANHOO sound insulation material should be selected for the interior wall of the shaft. Other non-brand materials will reduce the space of the elevator shaft, which is not conducive to the operation of the elevator. This situation occurs in many elevator projects. At the same time, the wall of the well is paved with other miscellaneous sound insulation and sound-absorbing materials, the durability is poor.
