Description
Art
The present invention relates to a kind of noise control technique field, especially can intercept the movable noise reduction barrier of construction equipment noise in construction site.
Background technology
Acoustic screen is a kind of sound insulation facility.It is in order to block direct sound between sound source and recipient, inserts a facility, make Acoustic Wave Propagation have a significant additional attenuation, thus weaken the influence of noise in the certain area at recipient place between sound source and recipient.In general, acoustic screen is higher, and enveloping surface is larger, and sound shadow region is larger, and sound insulation and noise reducing effect is better.
" disturbing residents " of causing due to decoration construction noise and resident are therefore to " people disturb " dispute that decoration construction scene is carried out, and relation huge numbers of families, become the focus of society.The noise that general construction machinery produces in work progress is all higher than " construction site ambient noise discharge standard " more than standard value 20dB.Due to great majority finishing, to lack shielding measure or construction machinery too near apart from sensitive point for noise, and the aerial natural decay rate of noise is low, and noise is crossed construction boundary and directly acted on sensitive point for noise, produces construction site noise thus and exceeds standard.Use acoustic screen to be isolated in the construction machinery noise source of strong noise and surrounding environment, make construction noise control in partiting sound member, to reduce pollution from environmental noise scope and degree of contamination.
Existing acoustic screen is fixed often, be difficult to carrying and reuse, even assembling noise barrier, also using steel work to be fixed on ground and install acoustic screen body again, to install and dismounting all brings a lot of trouble to arranging of the on-the-spot acoustic screen of decoration construction, be also unfavorable for reusing.And the decoration construction on-the-spot duration is shorter, fitting-out work completion is withdrawn at once, low in the urgent need to a kind of cost, install and the noise barrier of easy accessibility.
Summary of the invention
In order to overcome the deficiency that existing noise barrier is heavy, dismounting is inconvenient, setup cost is high, the invention provides a kind of movable noise reduction barrier, this movable noise reduction barrier can adapt to the on-the-spot Interim use of decoration construction, conveniently transports, installs and removes, reusable.
The technical solution adopted for the present invention to solve the technical problems is: movable noise reduction barrier is made up of main acoustic screen, side acoustic screen, daylighting observation port, universal wheel, hinge, flexible sound barrier.Each movable noise reduction barrier is made up of a main acoustic screen, two side acoustic screens.Main acoustic screen two limit uses hinge-coupled two side acoustic screens, and can rotate between 180 ° ~ 0 ° between main acoustic screen and side acoustic screen, point of attachment installs flexible sound barrier, passes through to connect escaping slot to prevent noise of equipment.Acoustic screen side, side arranges tongue and groove, and acoustic screen side, two sides tongue and groove can joggle mutually, and arrange elastic sealing strip in tongue and groove, inside the acoustic screen of side, tongue and groove is other arranges upper and lower two retraction type knockers.Arrange daylighting observation port in the middle part of main acoustic screen, daylighting observation port is made up of transparent PC force-bearing plate surrounding rubber weather strip.Daylighting observation port can provide light during work, and PC force-bearing plate can prevent the damaged security incident caused in work and handling process.Main acoustic screen, side acoustic screen are made up of steel structure frame, outer soundproof course, interior absorbent treatment, install outward in sound barrier fill out the outer cover glass silk cloth of porous absorption material and mask perforated plate at steel structure frame.Interior absorbent treatment can absorption equipment noise, reduce reflected sound, improve defening effect.Under the prerequisite meeting sound insulation factor and mechanical strength, steel structure frame and sound barrier make every effort to use lightweight material, reduce the weight of acoustic screen, the transport of portable propelling formula acoustic screen, installation and dismounting.For convenience of the movement of movable noise reduction barrier, install universal wheel bottom acoustic screen steel structure frame, the outer sound barrier bottom acoustic screen exceeds bottom steel structure frame, bottom universal wheel, close with ground, workplace, to reduce noise of equipment by propagating with the position on ground bottom steel structure frame.
For adapting to the different interior net storey heights of construction plant, the height of movable noise reduction barrier has high, medium and low three kinds of specifications, the main acoustic screen of same specification movable noise reduction barrier is identical with side acoustic screen height, the width of movable noise reduction barrier is unified, main acoustic screen width is two times of side acoustic screen, two side acoustic screens can be stacked on main acoustic screen by tongue and groove and retraction type knocker, convenient transport.In engineering, for the noise transmission of isolated a direction, single-unit activity formula acoustic screen can be used independently to use, also can by more than two or two movable noise reduction barrier, by the tongue and groove of side acoustic screen and the common composition of retraction type knocker combination complete surround formula acoustic screen, strong noise equipment and surrounding environment are isolated, makes construction noise control in partiting sound member, to reduce pollution from environmental noise scope and the degree of contamination of strong noise equipment.
The invention has the beneficial effects as follows, while can polluting meeting the on-the-spot noise decrease of decoration construction, the transport of portable propelling formula acoustic screen, installation and dismounting, reusable.
