Abstract
The utility model relates to an acoustic panel for an elevator liftway. The acoustic panel comprises a base panel body, wherein the base panel body is a glass fiber board, and a layer of inorganic mineral powder particles is bonded on the whole outer surface of the glass fiber board with bonding agent; the front surface of the acoustic panel for the elevator liftway is wavy, and the back surface of the acoustic panel for the elevator liftway is flat. Acoustic transmission mineral fines arranged on the outer layer of the acoustic panel protect the function of the internal glass fiber on the premise that the sound absorption function of the acoustic panel is not influenced and have the characteristics of fireproofing and incombustibility. The acoustic panel for the elevator liftway integrally reaches the fire rating A2 of the non-combustible construction material, and has the function of thermal insulation. The acoustic panel can effectively reduce the noise in the liftway and reduce the indoor noise in the household, has good fire-resisting material, a simple construction process and the function of thermal insulation and can be widely used for noise reduction in the elevator liftways and other buildings.
Description
Technical field
The utility model relates to a kind of abatvoix that is used to reduce the elevator hoistways noise.
Background technology
Noise of elevator is a common noise in the life, and its noise source is divided into elevator machine room noise and elevator hoistways noise again.At these two kinds of noise sources, different solutions is arranged.Wherein, the space is narrow and small in the elevator hoistways, and each plane is parallel to each other, and the easy mutual superposition of sound wave produces standing wave, and noise is amplified.To this, can adopt the method that abatvoix is installed in the hoistway to solve these problems.
The existing abatvoix that adopts glass wool board as stock is scattered in order to prevent glass fiber, need be at entrant sound fabrics such as the attached layer of non-woven fabric of plate face, or use parcels such as glass fabric, plastic sheeting.This kind method is not only produced and the construction technology complexity, and has influenced the noise reduction and the fireproof performance of abatvoix.Existing in addition abatvoix mostly is slabbed construction or opens circular hole on the plate surface, and configuration design is comparatively single, and is lower to the absorptive capacity of noise.
Summary of the invention
The utility model provides a kind of elevator hoistways abatvoix, and it is bad to solve existing abatvoix noise reduction and fireproof performance, produces and construction technology complicated technology problem.
The technical scheme that its technical problem that solves the utility model adopts is:
This elevator hoistways abatvoix comprises basic unit's plate body, and described basic unit plate body is a glass wool board, and glass wool board external surface integral body is bonded with one deck inorganic mineral powder granular by adhesive;
Described elevator hoistways abatvoix front is ups and downs wavy, and the back side is dull and stereotyped.
Described inorganic mineral powder granular is expanded vermiculite particle, alumina particle, montmorillonite particle, bentonite clay particle, sepiolite particle or palygorskite particle.
The particle diameter of described inorganic mineral powder granular is 10～30 orders.
The crest place sheet metal thickness of described elevator hoistways abatvoix is 40～60mm, and trough place sheet metal thickness is 30～50mm.
Spacing between the crest of described elevator hoistways abatvoix is 50mm～90mm.
Principle of the present utility model is as follows:
The elevator hoistways abatvoix is to utilize characteristic that sound absorption material can the absorption of noise energy and reduce noise near the characteristics that noise source improves sound absorption efficiency.The acoustics index of elevator hoistways abatvoix is an average sound absorption coefficient
With noise reduction coefficient NRC.Average sound absorption coefficient
Average for the sound absorption coefficient of 18 third-octaves between the 100-5000Hz.And NRC is a noise reduction coefficient, is the arithmetic mean of instantaneous value of 250Hz, 500Hz, these 4 octave band sound absorption coefficienies of 1000Hz, 2000Hz.Two indexes of this of elevator hoistways abatvoix are respectively
=0.77, NRC=0.85 reaches country-level standard.Wherein NRC numerical value is higher, and the absorption of sound of sensitive frequency is better more to human auditory system for the expression sound absorption material.
The physical significance of sound absorption coefficient is the absorptive capacity of sound absorption material to acoustic energy, and this numerical value is high more, and the acoustic energy that the expression material absorbs is big more.Especially can play better effect during near noise source when sound absorption material.And, can also prevent the generation of standing wave by using sound absorption material.
The beneficial effects of the utility model are as follows:
Elevator hoistways abatvoix of the present utility model, sticking and form by inner layer glass fiberboard and outer breeze by bonding agent.Skin is the entrant sound breeze, has under the prerequisite that does not influence the abatvoix sound absorption, and the protection internal glass fibers makes the not damaged function of flying away of glass fiber, and breeze itself also has the characteristics that fire prevention is not fired simultaneously.Elevator hoistways abatvoix integral body reaches the constructional materials fire-protection rating of not firing the A2 level, also has heat insulation function simultaneously, and coefficient of thermal conductivity is 0.029W/ (mK).
The profile of elevator hoistways abatvoix is convenient to on-site cutting, and the available special breeze coating in cutting back is repaired, and glass fiber is not exposed.Install back construction at elevator, use to fix nail and the elevator hoistways abatvoix is fixed with the hoistway body of wall got final product easy construction.
The utility model can effectively reduce the hoistway noise, reduce resident family's room noise, and the material fireproof performance is good, construction technology is simple, has the insulation effect concurrently, can be widely used in the noise reduction of elevator hoistways and other interior of buildings.
