Abstract
The utility model discloses a soundproof plate of a lift shaft, which comprises a back flat plate and a triangular wedged flat plate at the front, wherein the back is a layer of petroleum fiberboard; the rough front surface is a triangular wedged petroleum fiberboard; each plate is designed to be 1 square meter and fixed by screw spikes at inner walls of the lift shaft.
Description
Technical field
The utility model relates to a kind of silencing unit that is applied to the elevator hoistways inwall.
Background technology
Along with the development of social city, technicalization, hommization, real-estate market has obtained vigorous growth, and increasing high buildings and large mansions are rised sheer from level ground, and the thing followed is the increase of elevator use amount and showing of noise of elevator problem.The vibration that elevator produces in the running and noise can spread in the room in the mode of solid-borne sound transmission towards periphery by body of wall, the floor of building.Hoistway is narrow and small in the elevator, and gun iron link prolongs body of wall, end face, pillar provides strong actv. acoustic transmission medium.The people's who for a long time works, lives in the room that low-frequency noise is polluted hearing, the cardiovascular system nervous system of unifying is easily undermined, especially bad to the child's growth and development in the tire abdomen.
A lot of cinemas and domestic TV wall all adopt the rough method of wall to eliminate the noise, the muffler plate material that adopts now is the expanded materials such as expansion polyurethane or three amilan materials mostly, complicated process of preparation, and affected the fire-proof function of muffler plate, and existing most of silencing unit structures are single, much be to open several mouthfuls at flat board, soundproof effect is also not obvious.
Summary of the invention
The utility model provides a kind of silencing unit that is applied to the elevator hoistways inwall, solves simple in structure in the existing noise elimination technique, complex process, and sound-absorbing effect is not obvious, the technical matters such as can not prevent fires.
The problem that exists in order to solve prior art realizes above-mentioned purpose, and the utility model provides a kind of silencing unit that is applied to the elevator hoistways inwall.This elevator hoistways muffler plate is mainly fibrous by oil, and intensity is high, and fusing point is high, close structure, very light in weight.
Described elevator hoistways inwall silencing unit front is irregular male and fomale(M﹠F), and the back side is tabular.
Described oil fiber fluffy is staggered, has a large amount of small holes, is typical porous sound-absorbing material, has good sound absorption characteristics.
The dull and stereotyped place of described oil fiber is the oil board fiber board of the thick 32kg/m3 of one deck 2.5cm, and male and fomale(M﹠F) is the oil board fiber board of the thick 24kg/m3 of 2.5cm, and making the long section of 1m is the wedge of triangular form.
Principle of the present utility model is: the reason that the oil fiber can absorb sound is because have micro-pore and the hole of a large amount of inside and outside connections.When sound wave incided on the oil board fiber board, sound wave energy entered material internal along hole, caused the vibration of space Air molecule.Because the viscous resistance of air and the friction of air molecule and pore wall, acoustic energy is converted into heat energy and loss.
The ratio of material both sides air pressure and air rate when the air flow resistance is unit thickness.The air flow resistance is to affect the most important factor of oil board fiber board sound absorbing capabilities.Flow resistance is too little, and illustrative material is sparse, and air vibration easily passes, and sound absorbing capabilities descends; Flow resistance is too large, and illustrative material is closely knit, and air vibration is difficult to import into, and sound absorbing capabilities also descends.Be the oil board fiber board of 24 ~ 32 kg/m3 for the thick density of 2.5cm, there is best flow resistance in sound absorbing capabilities.
The beneficial effects of the utility model are as follows: sound absorption coefficient is high, and noise reduction coefficient NRC generally can reach more than 0.85.Construction costs is low, the shape that the muffler plate in the elevator hoistways can become to need with blade cuts, and section is that the male and fomale(M﹠F) of wedge of triangular form is attractive in appearance.Very light in weight, construction safety is convenient.
Oil fiber fusing point is that 250 degree fire resistances are good, difficulty is fired a level GB8621 B1 level, anti-soak properties are good, drainage is strong after the water logging, and sound absorption qualities does not descend, and form is constant, close structure, form stable, can directly be pasted and fixed on the elevator hoistways inwall, can use by secondary, destroy easily, harmless, environmentally safe, odorlessness.

The specific embodiment
As shown in Figure 2, the muffler plate of this elevator hoistways comprises that back side wedgelike dull and stereotyped and the front triangular form is dull and stereotyped, the back side is the oil board fiber board of the thick 32kg/m3 of one deck 2.5cm, male and fomale(M﹠F) is that the section of the thick 24kg/m3 of 2.5cm is the oil board fiber board of triangular form wedgelike, every tabular 1 ㎡ that is designed to is fixed on the elevator hoistways inwall with spiral nail.The concrete installation method of the utility model is: elevator hoistways (1) inner wall washing is clean, guarantee the level and smooth of elevator hoistways (1) inwall, size according to elevator hoistways (1) inwall, be that the muffler plate (2) of 1 ㎡ fits tightly on elevator hoistways (1) inwall with area, guarantee male and fomale(M﹠F) towards lift car (3), fit tightly between plate and the plate and align, as shown in Figure 1, cut if necessary, be cropped neat and be fixed on hoistway (1) inwall with spiral nail (4) afterwards.
