Abstract
The utility model discloses a sound barrier, which is formed by assembling a plurality of sound absorbing and insulating units. The sound absorbing and insulating units respectively comprise a front shell (10), a rear shell (11) and a sound absorbing and insulating component (3), the left end and the right end of the insulating component (3) are respectively provided with a head sealing plate (4), and the left ends and the right ends of the sound absorbing and insulating units are inserted in an I-shaped channel steel column (19) as a whole through the head sealing plates (4) in the horizontal direction. The utility model has the advantages of simple overall structure and convenient installation and removal. Due to the head sealing plates, the utility model can effectively improve the overall solidity, and avoid direct contact of the I-shaped channel steel column (19) for installation and the shells, thereby preventing the I-shaped channel steel column (19) from being easily damaged under wind pressure or during pulsation. Simultaneously, the width of the I-shaped channel steel column (19) is only required to be matched with the width of the sound absorbing and insulating components, thereby reducing the consumption of the I-shaped channel steel column (19) and saving the cost.
Description
Technical field
The utility model belongs to the high-speed railway bridge technical field, relates to a kind of sound barrier concretely.
Background technology
Sound barrier is to be used for absorbing and the through sonic propagation in noise isolation source, the sound absorption that between noise source and recipient, is provided with and the shielding harness that insulates against sound, and it is placed in the sound shadow region recipient, and propagation of noise is wherein had isolation effect preferably.Developing rapidly of high-speed railway produces a large amount of noise pollutions now, and sound barrier takes up an area of few, and fabrication and installation are convenient and swift, and construction investment is suitable, become the important measures of traffic noise pollution control.
Sound wave runs into that sound barrier can reflect, projection and three kinds of phenomenons of diffraction in communication process.Usually we think that sound barrier can stop through sonic propagation, and make system penetrate sound enough decay are arranged, and the influence of projection sound can be ignored.Therefore, the sound absorption effect of sound barrier generally can adopt the noise abatement amount to represent, it has reflected the ability of the above-mentioned two kinds of shielding entrant sounds of sound barrier.Insert a sound barrier between sound source and receiving station, establish the sound barrier endless, sound wave can only be gone over from the top diffraction of barrier, and forms a sound shadow region thereafter, forms a shade just as light is blocked by object.In this sound shadow region, people can feel that noise has obviously weakened, the noise reduction effect of Here it is sound barrier.
Insert a facility between sound source and recipient, sound wave is propagated a significant additional attenuation, thereby weakens the influence of noise in certain zone at recipient place, and such facility is called as sound barrier.This sound barrier is widely used in countries in the world, especially in recent years high-speed railway develops rapidly, various countries have also carried out many research to high speed railway sound barrier, have also carried out deep research and a large amount of practices aspect the design and construction of high speed railway sound barrier.
Present known noise barrier structure form mainly contains following several:
Flap type:
Do supporting body with the blinds slotted hole, inner filling sucting sound material (as rock wool etc.) is one of sound barrier form of extensive use the most.Facing to noise source simultaneously is the blinds slotted hole, and internal cavities is all filled out sound absorption material (as rock wool, centrifugally glass-wool, fiberboard etc.).
2, perforation template:
Do supporting body with perforated plate, inner filling sucting sound material (as rock wool etc.) is one of most widely used sound barrier form.As shown in Figure 5, be a kind of known noise barrier structure schematic diagram.Described sound barrier is a perforated plate facing to the panel 102 of noise source one side, the whole filling sucting sound materials 104 of internal cavities (as rock wool, centrifugally glass-wool, fiberboard etc.), away from the backboard 103 of noise source one side is the perforated plate identical with panel 102, or adopts the metal sheet with certain intensity.
3, Chinese patent, the patent No. 00263317, " folded plate type composite sound absorbing barrier " discloses a kind of absorbent lined barrier of being made up of underframe and upper casing, and it is filled with foam glass in underframe, the front of upper casing is a microperforated panel, and this microperforated panel is formed with the upper casing that is positioned at its back a cavity.
Above-mentioned present known filled-type sound barrier, all be to adopt different opening forms, the inner sound absorption material of all filling, for reaching enough sound absorption and insulation effects, sound barrier has certain thickness, about general 100-200mm, but this known noise barrier structure is all in total defective: must fill a large amount of sound absorption materials, while sound absorption material light weight, defening effect is not good, causes the whole defening effect of sound barrier undesirable.No. 00263317 disclosed " folded plate type composite sound absorbing barrier " its underpart of described Chinese patent is the filled-type sound barrier, its top is a hollow cavity, and therefore, there is above-mentioned defective equally in its underpart, and its top only is a hollow cavity, and its defening effect is poorer than the bottom.
4, No. 200820109162.9, Chinese patent, " a kind of sound barrier " discloses a kind of sound barrier 201 as Fig. 6 and has been made up of panel 202 and backboard 207, be provided with sound absorber 203 and acoustic isolater 205 between panel 202 and the backboard 207, equidistant cavity layer 206 before and after forming between sound absorber 203 and acoustic isolater 205 and panel and the backboard, the noise barrier of hollow before and after forming.Whole housing is inserted in the I-shaped steel tank when adopting this structure-borne sound barrier to splice in the horizontal direction, there are following 2 deficiencies in this structure: (1), panel and backboard directly directly contact with the i iron column, bear blast and pulsating, panel and backboard damage easily, significantly reduce its application life.(2), the integral thickness that will reach its sound barrier of sound insulation standard has requirement, under the prerequisite that guarantees thickness, whole when inserting i-beam structure corresponding i iron need certain width to match, the i iron consumption is big, the cost height.
The utility model content
The purpose of this utility model is to provide a kind of can improve the sound barrier firmness, guarantees that it holds wind stability, not fragile, can also reduce a kind of sound barrier of i iron column consumption simultaneously
The technical solution of the utility model is as follows:
