Abstract
A movable noise reduction barrier comprises a main noise reduction barrier, side noise reduction barriers, a lighting inspection window, universal wheels, hinges and flexible noise barriers, wherein the main noise reduction barrier and the side noise reduction barriers consist of steel structure frames, outer noise reduction layers and inner noise reduction layers; two sides of the main noise reduction barrier are connected with two side noise reduction barrier bodies through the hinges; the universal wheels are mounted at the bottoms of the steel structure frames of the noise reduction barriers; concave-convex grooves are formed in side surfaces of the side noise reduction barriers; the concave-convex grooves in the side surfaces of the two side noise reduction barriers can be in joggle joint with each other; elastic sealing strips are arranged in the concave-convex grooves; an upper retraction type door holder and a lower retraction type door holder are arranged beside concave-convex grooves on inner sides of the side noise reduction barriers. A single movable noise reduction barrier is used independently, or two or more movable noise reduction barriers are combined to jointly form an integrated surrounding noise reduction barrier through the concave-convex grooves and the retraction type door holders. The transportation, mounting and dismantling of the movable noise reduction barrier are facilitated while the noise pollution of the decoration sites can be reduced, and the movable noise reduction barrier can be repeatedly used.
Description
Affiliated technical field
The present invention relates to a kind of noise control technique field, especially can intercept the movable acoustic screen of construction equipment noise in the construction site.
Background technology
Acoustic screen is a kind of sound insulation facility.It inserts a facility in order to block direct sound between sound source and recipient between sound source and recipient, make Acoustic Wave Propagation that a significant additional attenuation be arranged, thereby weakens the interior influence of noise of certain area at recipient place.In general, acoustic screen is higher, and enveloping surface is larger, and the sound shadow region is larger, and the sound insulation and noise reducing effect is better.
" people disturb " dispute that therefore " the disturbing residents " that causes due to the decoration construction noise and resident carry out the decoration construction scene concerns huge numbers of families, becomes 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 finishings lack shielding measure or construction machinery too near apart from sensitive point for noise, the aerial natural decay rate of noise is low, noise is crossed the construction boundary and is directly acted on sensitive point for noise, produces thus the construction site noise and exceeds standard.Use acoustic screen with construction machinery noise source and the surrounding environment isolation of strong noise, construction noise is controlled 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 the assembling noise barrier also uses steel work to be fixed on ground and installs the acoustic screen body again, install and dismantle and all bring a lot of troubles for arranging of the on-the-spot acoustic screen of decoration construction, also be unfavorable for reusing.And the on-the-spot duration of decoration construction is shorter, and the fitting-out work completion is withdrawn at once, the noise barrier of, installation low in the urgent need to a kind of cost and 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 acoustic screen, this movable acoustic screen can adapt to the on-the-spot Interim use of decoration construction, conveniently transports, installs and remove, and is reusable.
The technical solution adopted for the present invention to solve the technical problems is: movable acoustic screen is made of main acoustic screen, side acoustic screen, daylighting observation port, universal wheel, hinge, flexible sound barrier.Each movable acoustic screen is comprised of a main acoustic screen, two side acoustic screens.Two side acoustic screens of hinge-coupled are used on main acoustic screen two limits, can rotate between 180 ° ~ 0 ° between main acoustic screen and side acoustic screen, and point of attachment is installed flexible sound barrier, to prevent that noise of equipment is by connecting escaping slot.Side acoustic screen side arranges tongue and groove, and two side acoustic screen side tongue and grooves are joggle mutually, and elastic sealing strip is set in tongue and groove, and the inboard tongue and groove of side acoustic screen is other arranges upper and lower two retraction type knockers.Main acoustic screen middle part arranges the daylighting observation port, and the daylighting observation port is made by transparent PC force-bearing plate surrounding rubber weather strip.Light when the daylighting observation port can provide work, PC force-bearing plate can prevent the damaged security incident that causes in work and handling process.Main acoustic screen, side acoustic screen are comprised of steel structure frame, outer soundproof course, interior absorbent treatment, install outside steel structure frame and fill out cover glass silk cloth and mask perforated plate outside porous absorption material in sound barrier.Interior absorbent treatment can the absorption equipment noise, reduce reflected sound, improve defening effect.Under the prerequisite that satisfies 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, transportation, installation and the dismounting of portable propelling formula acoustic screen.Movement for convenience of movable acoustic screen, outer sound barrier bottom acoustic screen steel structure frame bottom installation universal wheel, acoustic screen exceeds bottom steel structure frame, near the universal wheel bottom, approach with ground, workplace, propagate by the position on steel structure frame bottom and ground to reduce noise of equipment.
For adapting to the different interior net storey heights of construction plant, the height of movable acoustic screen has high, medium and low three kinds of specifications, the main acoustic screen of the movable acoustic screen of same specification is identical with side acoustic screen height, the width of movable acoustic screen is unified, main acoustic screen width is two times of side acoustic screen, can two side acoustic screens be stacked on main acoustic screen by tongue and groove and retraction type knocker convenient transportation.In engineering, noise transmission for isolated a direction, can use single-unit activity formula acoustic screen independently to use, also can be with movable acoustic screen more than two or two, tongue and groove by the side acoustic screen and the combination of retraction type knocker be common forms the complete formula acoustic screen that surrounds, with strong noise equipment and surrounding environment isolation, construction noise is controlled 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, can be when satisfying the on-the-spot noise decrease pollution of decoration construction, transportation, installation and the dismounting of portable propelling formula acoustic screen, reusable.
