Abstract

The utility model discloses a noise-reducing sound-absorbing device applicable to an elevator well, which is a square sound-absorbing passage arranged on the inner side of the elevator well wall. The square sound-absorbing passage is formed by assembling a plurality of noise-reducing sound-absorbing boards; each noise-reducing sound-absorbing board is composed of a layer of plane sound-absorbing substrate and a layer of waved sound-insulating board, the plane sound-absorbing substrate is made of glass fiber cotton, and the waved sound-insulating board is stuck to one surface of the plane sound-absorbing substrate in a compositing manner, and made of vermiculite particles to be pressed to take the shape of undulant waves. The noise-reducing sound-absorbing boards is a specially-made sound absorption material, specially used in the elevator well and a computer room needing sound insulation and noise reduction, formed by spraying and compositing a nanometer fiber material and fibers according to a fixed ratio, and provided with the specific waved surface structures formed by pressing; with the special structures on the surfaces, the sound-absorbing range of the noise-reducing sound-absorbing boards is widened, so that noise generated in an elevator running process can be effectively absorbed, and meanwhile, the reflection effect of a sound source is changed to achieve a noise barrier effect.

Description

A kind of noise reduction sound arrester that is applicable to elevator hoistways
Technical field
The utility model belongs to noise abatement device technique field, relates to specifically a kind of noise reduction sound arrester that is applicable to elevator hoistways.
Background technology
Noise of elevator is common noise in life, and its noise source is divided into again elevator(lift) machine room noise and elevator hoistways noise, and the daily life of elevator hoistways noise on human impact is larger conventionally.Due to narrow space in elevator hoistways, and each plane is parallel to each other, and sound wave is stack and produce standing wave mutually easily, thereby noise is amplified.In prior art, conventionally adopt the method that abatvoix is installed in hoistway to solve this problem, abatvoix of the prior art is generally slabbed construction or opens circular hole on abatvoix surface, this abatvoix configuration design of the prior art is comparatively single, noise reduction and the fire resistance of abatvoix are poor, lower to the absorption power of noise.So need badly, the abatvoix of elevator hoistways is carried out to necessary design and perfect, design a kind of simple in structure, elevator hoistways noise reduction sound arrester that noise reduction sound-absorbing effect is good.
Summary of the invention
The deficiency that the utility model exists in order to overcome prior art, provides a kind of simple in structure and can effectively fall the low noise noise reduction sound arrester that is applicable to elevator hoistways.
The utility model is achieved through the following technical solutions: a kind of noise reduction sound arrester that is applicable to elevator hoistways, it is the square sound-absorbing passage that is arranged at hoistway wall inner side, square sound-absorbing passage is combined by polylith noise-reducing acoustic board, noise-reducing acoustic board consists of a layer plane sound-absorbing substrate and one deck waveform insulation board and panel, plane sound-absorbing substrate consists of glass fibre cotton, surface recombination at plane sound-absorbing substrate is bonded with waveform insulation board and panel, waveform insulation board and panel consists of vermiculite granule, and vermiculite granule is compressed to the waveform that height rises and falls.
Described glass fibre cotton is nano-grade glass fibre cotton.
Described vermiculite granule is compounded on the surface of plane sound-absorbing substrate through fiber coating.
Described noise-reducing acoustic board is of a size of 50mm*600mm*600mm.
Elevator hoistways noise-reducing acoustic board is to utilize the characteristic that sound-absorbing material can absorption of noise energy and approach the feature that noise source improves sound absorption efficiency to reduce noise, by using sound-absorbing material can also prevent the generation of standing wave.Noise reduction sound arrester of the present utility model can be used in the sound insulation and noise reducing of elevator hoistways, hoistway and subway, and Qi Jing national authority inspection center is detected, and its noise insulation factor reaches 51dB, and sound insulation property is one-level, and fire resistance is excellent, reaches A level and does not fire.
The beneficial effects of the utility model are: noise-reducing acoustic board of the present utility model be specially for elevator hoistways, machine room need to insulate against sound, noise reduction and the sound-absorbing material of special facture, it is by fixedly nano-fiber material, the fiber coating of proportion are composited, and the distinctive waveform surface texture of repressed formation, its surperficial special construction has expanded sound absorption scope, can effectively absorb the noise producing in running process of elevator, changed again the reflecting effect of sound source, formed sound-proof wall effect simultaneously.The utility model can effectively reduce elevator hoistways noise, reduce resident family's room noise, and material fire resistance is good, construction technology is simple, has insulation effect concurrently, can be widely used in the noise reduction of elevator hoistways and other interior of buildings.The utility model can effectively reduce the level of noise of elevator hoistways, meets inhabitation required standard, to improving people's quality of life, create quiet living environment tool and be of great significance.
