Abstract
The utility model belongs to the technical field of sound barriers and discloses a sound barrier used for being arranged at the two sides of a highway and a railway and eliminating noise. According to the technical scheme, the sound barrier is composed of at least two uprights respectively provided with an H-shaped section and a plurality of sound barrier unit boards inserted between every two adjacent uprights. Each upright is composed of a vertical upright inclined inwards and an inclined upright connected to the top of the vertical upright. The sound barrier of the structure has the advantages of being reasonable in structure and good in noise blocking and eliminating effect.
Description
Technical field
The utility model belongs to the sound barrier technical field, discloses specifically a kind of speedway, the sound barrier of railway both sides for isolating and abating the noise of being used in.
Background technology
Sound barrier be arranged at highway or railway both sides a kind of can be effectively to the train of running at high speed, noise isolation that automobile produces and the mechanism of elimination.Sound barrier is is the board plug type structure that H shaped steel column and unit board combine by cross section.Be sound barrier some steel posts that are 200-400 centimetres by spacing distance along road alternately, insert the sound barrier that the acoustic barrier unit board of 30-100 centimetres wide forms the control noise of railway both sides between H shaped steel column.The acoustic barrier unit board structure of using at present consists of backboard, panel and the cement fibrolite plate, sound absorption rock wool and the metal support block that are sandwiched in therebetween, and form after the backboard, panel snapping of sound barrier shell by fixing with rivet, folded cement fibrolite plate supports by the metal support block that is arranged at surrounding, and rock wool is fixed on cement fibrolite plate by screw and pad in sound absorption.Due to noise, the reflected refraction on unit board causes its phenomenon to external diffusion to occur to this structure-borne sound barrier, exists the defect of blocking noise weak effect.
the content of utility model
The purpose of this utility model just is to provide a kind of stopping and the effect sound barrier preferably that abates the noise.
Realize that the technical scheme that the utility model above-mentioned purpose proposes is:
A kind of sound barrier, some acoustic barrier unit boards that the column that to comprise by least two cross sections be the H type and card insert between adjacent two described columns combine; Wherein, described column consists of skewed to the inside mullion and the oblique post that is connected in its top.
The additional technical feature that forms above-mentioned a kind of sound barrier also comprises:
---the top that forms the mullion of described column is provided with the breach for the plug-in card acoustic barrier unit board;
---the angle of inclination of described mullion is at 1-10 degree;
---the end that forms the oblique post of described column is provided with semicircle hook, and is provided with columniform sound-absorbing spreader body on this hook;
---described acoustic barrier unit board consists of the glass reinforced plastic panel that is provided with sound-absorption hole, reinforced fibreglass back board and the polyurethane foam board that is sandwiched between the two;
---described glass reinforced plastic panel is irregular male and fomale(M&F) structure.
Sound barrier provided by the utility model, compared with prior art have the following advantages: one, because the column that forms sound barrier consists of skewed to the inside mullion and the oblique post that is connected in its top, so the acoustic barrier unit board of the oblique intercolumniation of plug-in card column has formed sound insulation slab; They are two years old, owing on the panel that forms acoustic barrier unit board, being provided with sound-absorption hole, and be set to irregular concave/convex-shaped structure, therefore not only can reach by sound-absorption hole the effect of sound-absorbing, but also can reach the effect to sound reflection and refraction by concave/convex-shaped structure, improved the sound-absorbing effect of sound-absorption hole; Its three, form the polyurethane material of acoustic barrier unit board, not only sound-absorbing sound insulation, and can firmly form firmly overall structure with panel, backboard; And because the non-absorbency of this material can be able to effectively be avoided the empty phenomenon generation of pendant in acoustic barrier unit board formation chamber.
The accompanying drawing explanation
Fig. 1: be the plan structure schematic diagram of sound barrier;
Fig. 2: for forming the structural representation of noise barrier stand column;
Fig. 3: for forming the cross section structure schematic diagram of acoustic barrier unit board.
The specific embodiment
The structure of a kind of sound barrier the utility model provided below in conjunction with accompanying drawing is described in further detail:
As shown in Figure 1, 2 for forming the structural representation of the sound barrier that the utility model provides, its structure comprises that three cross sections are H type by mullion 2 be connected in the column 1 that the oblique post 3 at its top forms, and is inserted with at 2 folded sieve cards of adjacent two mullions 3 folded sieve cards of unit board 4, oblique post that three acoustic barrier unit boards 41,42,43 form and is inserted with an acoustic barrier unit board 44.
In the structure of above-mentioned sound barrier,
---insert acoustic barrier unit board 41,42,43 for convenient at 2 cards of mullion, be provided with the breach 5 for the plug-in card acoustic barrier unit board at the top of mullion;
---for isolation and the absorption of the noise that more is conducive to automobile or train are produced, by form column mullion 2 be set to the angle of inclination a to noise source to 1-10 degree; Be provided with semicircle hook 6 in the end that forms the oblique post of column, and be provided with columniform sound-absorbing spreader body 7 on this hook;
---form the unit board of above-mentioned sound barrier as shown in Figure 3, formed by the glass reinforced plastic panel 9 that is provided with sound-absorption hole 8, reinforced fibreglass back board 10 and the polyurethane foam board 11 that is sandwiched between the two, and the plate face of glass reinforced plastic panel is set to irregular male and fomale(M&F) structure 12.Wherein sound-absorption hole 8 is for absorbing noise, and the noise ripple that its 12 pairs, irregular male and fomale(M&F) structure is not absorbed by sound-absorption hole carries out irregular refraction reflection, on the basis that reduces the noise decibel, within last minute, is entering sound-absorption hole, thereby reaches the purpose that reduces noise.
---when by the male and fomale(M&F) structure, carrying out random scatters, the horizontal cylinder 7 of sound-absorbing be arranged on hook can play blocking noise to external diffusion and have the effect of lingering sound convergence, thereby has reached the purpose of the maximum noise reduction of sound barrier.
