Description
Technical field
The utility model relates to noise abatement equipment technical field, particularly relates to a kind of noise barrier.
Background technology
In order to block the direct sound between sound source and recipient, between sound source and recipient, inserting a facility, make Acoustic Wave Propagation have a significant additional attenuation, thus weaken the influence of noise in recipient region.This facility is noise barrier, and noise barrier is primarily of steel structural upright column and the dull and stereotyped two parts composition of sound absorption.Column is the main bearing member of noise barrier, and sound absorption flat board is fixed in H type column groove by high-strength spring clip by it, forms noise barrier.
Sound wave, in communication process, when running into noise barrier, will to reflect, transmission and diffraction three kinds of phenomenons.Usually we think that barrier can stop through sonic propagation, and make diffraction sound have enough decay.Run into obstruction in Acoustic Wave Propagation and produce diffraction phenomena, similar to the diffraction phenomena of object to light-wave irradiation, there is shadow region after being blocked in light by opaque object after bar, and sound wave produces " sound shadow region ", the principle of noise barrier sound insulation that Here it is.
Common noise barrier is divided into fixed noise barrier, segmented noise barrier and hanging type folding noise barrier.Fixed noise barrier, is artificial indoor are divided into two regions, takes up room large, barrier set up after personnel and material turnover very inconvenient.Segmented noise barrier is that whole noise barrier is divided into one section one section, each section is an active unit, need to be stitched together during noise barrier, active unit is one by one split as when not needing, this active unit needs to install castor, and bottom needs wider floor, causes the height of this noise barrier to be limited, not so can topple, bring potential safety hazard.Hanging type folding noise barrier sets up a track, barrier can be divided into very little unit, and can folding storage be carried out, height, stability, the safety of such barrier and take up room little etc. all satisfied, but crossbeam is arranged at top, drive a vehicle through out-of-date inconvenience, in addition due to the reason of structural strength, span is limited, affects the normal use of noise barrier.
