Abstract
The utility model relates to a light composite board barrier with holes capable of absorbing and insulating noise, which is composed of a front panel, an intermediate layer and a back plate which are overlapped; the front panel is composed of cement and bone materials which are solidified and is distributed with inclined through holes with the high back and the low front; the intermediate layer is one layer or more than one layer of sound-absorbing materials; the back panel is composed of cement and bone materials which are solidified; each layer overlapped is connected by metal components in series or is glued by adhesive materials. When the utility model is assembled, one surface with holes is faced to a noise source; noise which enters the intermediate layer through a passage of the front panel of the barrier is absorbed and eliminated by the sound-absorbing materials; the passage inclined from top down can avoid the entering of the rain and can not be blocked by dust; the back panel mainly plays roles of sound insulating, pressure resistance and loadbearing. The multilayer structure which becomes a whole plays roles of themselves, and thus, the sound absorption effect is obviously enhanced.
Description
[technical field]
The utility model is a kind of sound barrier that outdoor engineering services such as urban road, track traffic, highway, railway are eliminated noise that is used for.
[background technology]
For administering the noise nuisance that facilities such as arterial traffic such as urban track traffic, highway, railway produce, often adopt concrete plate to intercept noise.Because concrete plate generally can only reflect noise, do not possess sound absorption, the effect of improvement is generally bad.Idol has some concrete plates to form small acicular pores in the hope of acoustically effective through the foaming back, but sound absorption coefficient is very low, in case and acicular pores stopped up by dust and rainwater mixture, more can reduce sound absorption.
[summary of the invention]
The purpose of this utility model provides a kind of sound absorption light composite board sound barrier with holes, can keep the cheap advantage of original concrete plate, can have sound absorption, sound insulation, anticlogging effect again.
The technical solution of the utility model is: a kind of sound absorption light composite board sound barrier with holes, it is characterized in that, form by front panel, intermediate layer, the stack of rear board sandwich construction, front panel is solidified by cement and aggregate and forms and be uniform-distribution with the high preceding low oblique through hole in back, the intermediate layer is one or more layers of sound absorption material, rear board is solidified by cement and aggregate and forms, and is bonding with metalwork polyphone or binding material after each stacked adding.
One deck structure that the intermediate layer can be made of the damping material of any state in block, granular, fibrous; Also can be mixed into one deck structure by block, granular or fibrous damping material, can also be by the bonding sandwich construction that forms of block, granular or fibrous damping material hierarchal arrangement.
The oblique through hole cross section of above-mentioned front panel generally is not less than 15 square millimeters, otherwise is stopped up by dust easily.
When this sound barrier is installed porose one side face of noise source, noise enters the intermediate layer by sound barrier front panel duct and absorbs elimination by sound absorption material, because of the duct tilts from top to bottom, can prevent that rainwater from entering and can not stopped up that rear board mainly plays sound insulation and resistance to compression carrying effect by dust.This sandwich construction becomes one, and works according to his ability, and sound-absorbing effect obviously improves.
The utility model compared with prior art, advantage is obvious.It has that anti-rainwater, sound absorption effect are good, long service life, advantage such as of many uses, and because of dismantling the no value in back, is particularly suitable for being installed in the regional and location do not gazed at of noise-sensitive.
[description of drawings]
Fig. 1 is the user mode schematic diagram of the utility model embodiment.
Fig. 2 is the side sectional view of the utility model embodiment.
[specific embodiment]
Be described in further detail below in conjunction with the utility model embodiment and accompanying drawing thereof.
Consult each accompanying drawing.A kind of sound absorption light composite board sound barrier with holes is made up of the sandwich construction stack of front panel 2, intermediate layer 4, rear board 5.Front panel 2 is solidified by cement and aggregate and forms and be uniform-distribution with the high preceding low oblique through hole 3 in back, aggregate is herein generally got fiber product, the oblique through hole cross section of front panel can adopt well-regulated shape, as rectangle, circle, rhombus etc., it also can be irregular shape, cross sectional area generally is not less than 15 square millimeters, otherwise is stopped up by dust easily.Intermediate layer 4 is one or more layers of sound absorption material, one deck structure that can be made of the damping material of any state in block, granular, fibrous; Also can be mixed into one deck structure by block, granular or fibrous damping material, can also be by the bonding sandwich construction that forms of block, granular or fibrous damping material hierarchal arrangement.Rear board 5 is solidified by cement and aggregate and forms, and aggregate can be a reinforcing bar herein, also can be fibrous material.With metalwork polyphone (because this is characterized as known technology, not shown) or bonding with binding material, binding material employing cement or building glue can after all each stacked adding.Use when installing as long as fixedly connected one by one towards noise source with column 1 the porose one side of this sound barrier.
