Industry information: elevator well track sound insulation scheme

When the elevator is running, it will produce noise and noise. To a certain extent, it will reflect the quality of elevator when installed, whether the technology is in place, or whether the product itself has reached the relevant noise indicators. In the process of production and manufacture, we can reduce or even eliminate the noise through the processing of sound insulation and shock absorption for elevator. Starting from the source of noise is a urgent and perfect task for elevator operation.
In the process of reducing the noise of the elevator, the transformation of the elevator track in the well is also an important part. At present, the elevator hoistway noise transformation scheme, main methods used are mainly equipped with soundproof felt as damping pad; or mounting rail vibration and noise reduction device, which can reduce the structural transmission shaft. However, it needs to transform the elevator which is already in use. Not only do we need to remove the elevator related components, but also the construction technology is more complicated, which will affect the normal use of the elevator. Therefore, we need further upgrading to meet the needs of the elevator.
Next, let's introduce a more important technology in the elevator noise modification engineering. The main content of this method is to add sound insulation wall between elevator shaft and room. The specific content of this practice can refer to the network books, have a detailed introduction. This approach is smaller to the elevator hoistway space, but also the operation of the elevator without any hindrance effect, good safety; but because of the complexity of the construction process, has a certain effect on the size of the room space, especially for the current, an inch of an inch of gold in the room, most of the real estate developers are not considered.
Another part of the plan is the sound insulation treatment of the inner wall of the elevator shaft, for example, adding environmentally friendly polyester, sound and cotton and gradient sound absorbing cotton and other healthy and sound insulation materials in the well way. At present, the conventional way in the auxiliary scheme of elevator energy saver is to lay sound insulation materials on the inner wall of well, such as sound absorbent cotton, etc., and do some protective measures outside, which can also play a good role in soundproof.
In the implementation process, there is a kind of practice is to use the "elevator hoistway wall wall base + Green + cotton insulation on wooden keel nail steel wire mesh and cement mortar". This practice has sound absorption effect, but there are some problems in the construction, especially for paving cotton insulation practices, because the cement mortar smeared in insulation cotton, wire mesh outside, low bond strength of cement mortar, easy to crack and fall off, so the durability of the wall is not good. Of course, in order to solve the problems, to meet the needs of intelligent designer has developed a better way, such as the use of the elevator hoistway wall wall base + nail 2mm high barrier acoustic felt + nail steel wire with a layer of +50px thick cement mortar "approach. This method is better than the first one, because the cement mortar can be better bonded on the wire net. But for the limited size of the elevator shaft, shaft wall paving sound-absorbing insulation materials to choose sound-absorbing insulation material environmental protection and high efficiency, with other non brand materials will reduce the space elevator well, is not conducive to the operation of the elevator, the elevator has appeared in many projects in energy conservation project.
But at the same time, the relevant technicians also pointed out that if we want to save money and lay other inferior sound insulation and sound absorbing materials on the inner wall of the well, the sound insulation effect is not only bad, but also may affect the use of the wall of the elevator shaft, so we must be cautious.
