Description
Technical field
The present invention relates to a kind of dismountable sound barrier transparent acoustic screen.
Background technology
In recent years, along with socio-economic development, urbanization process is accelerated, highway, railway, urban road, city rail etc.
Public transport infrastructure obtains fast development, and it is while promoting economic development and promoting national life level, generation
Environmental Communication influence of noise pollution also becomes increasingly conspicuous, and solving pollution from environmental noise problem is to carry out " 13 " planning construction
The inevitable requirement of conservation culture society.National environmental protection portion from technology governance angle issued " traffic above-ground sound pollution prevent
Control technical policy ", technical policy proposes, from intercepting transaudient approach, the project slash paying the utmost attention to arrange sound barrier noise reduction,
Noise-sensitive structure is laid special stress on protecting.Current domestic noise barrier structure pattern mostly is vertical type and optimizes deformation (top
Portion's infolding arc, inverted L shape or band top sound absorber), this type of barrier is because being limited by structure height (between highly 2～7 meters), and noise reduction is imitated
Fruit generally 5～10 dB (A)；When to road or track both sides being high-rise noise-sensitive structure, Sheng Zhao district noise reduction is bright
Aobvious reduction or almost nil.Semiclosed/totally-enclosed sound barrier can effectively solve traditional screen barrier and cause noise reduction fall because of sound diffraction
Low defect, has the notable noise reduction of more than 20 dB (A), the most obtains in urban transportation sensitivity building concentrated area
Extensively application.
Inventor is by runing and in the vertical type built and optimization deformation, the technology of semiclosed or totally-enclosed barrier
Investigation and consult analysis relevant sound barrier patent find, the sound barrier unit screen of noise reduction all use absorbing sound type sound absorbing-insulating and
Septum pellucidum sound-screen plug-in mounting in order is fixed in H profile steel column or is fixed on semiclosed/totally-enclosed barrier portal frame column
Outside, for septum pellucidum sound-screen, after its transparent material is formed integrally admittedly with aluminium alloy extrusions frame or other hardware frame assembly
It is installed on and constitutes the sound insulation unit block of sound barrier on above-mentioned steel frame column, therefore the existing structure technology of septum pellucidum sound-screen
Techniques below defect is there is in installation or the operation repair and maintenance stage of sound barrier:
1) septum pellucidum sound-screen uses transparent sound insulation sheet material and frame assembling fixed structure, and septum pellucidum sound-screen is being installed or in repair and maintenance,
Cracking or damaged and need to change is there is, invar column frame or the stop of sound absorbing-insulating and nothing on it once transparent sound insulation sheet material
Method realizes quick-replaceable, need to first dismantle position whole sound absorption unit pieces to its upper and just can carry out, and changes operation loaded down with trivial details, limits
Condition is many, abnormal inconvenient；
2) for semiclosed/totally-enclosed sound barrier, due to steel column upper cover steel cap and the stop of back roofing enclosure, thoroughly
The damage of bright acoustic screen changes and is difficult to especially (in the traffic operation stage, dismantle upper cover steel cap and back roofing seals knot
Structure, needs temporary closure traffic or stops operation, negatively affects urban transportation operation and social life greatly, and changes work
Amount and difficulty of construction are big, there is higher security risk), bring if the most quickly changeing and road traffic or rail can be shipped row
Severe compromise.
3) being installed on overhead section of sound barrier, because of the highest, above-mentioned septum pellucidum sound-screen can only clean in the maintenance washes stage
Facing road or track side sheet material, its dorsal part cannot realize cleaning, even if use expensive special high-altitude cleaning Operation Van also
Often cannot realize because traffic above-ground limits (overhead cross a river lake or building etc.), the repair and maintenance maintenance considerably increasing acoustic screen is difficult
Degree and maintenance cost.
Summary of the invention
In order to solve the technical deficiency of existing septum pellucidum sound-screen, reduce repair and maintenance difficulty and the repair and maintenance cost of sound barrier, this
The bright dismountable structure providing a kind of sound barrier transparent acoustic screen, realizes transparent sound insulation sheet material by dismountable press strip
Quick-replaceable or cleaning, and guarantee its structure can bear steadily in the long term wind load and can bear in track traffic train produce
The percussion of pulsating wind loading.
A kind of dismountable sound barrier transparent acoustic screen, described septum pellucidum sound-screen is quadrilateral structure, described tetragon
Structure intermediate seal inlays transparent sound insulation sheet material, and quadrilateral structure is made up of fixed border and dismountable press strip, described removable
Dress formula press strip is removably attached on fixed border by fixing device.
Described fixed border is fixed into stable quadrilateral structure by fixation kit, and described fixed border has long L-shaped
Groove, places rubber blanket and U-shaped adhesive tape in described long L-shaped groove, the marginal portion of described transparent sound insulation sheet material is arranged at U-shaped glue
In the U-shaped structure of bar.
The end of described fixed border is cut into 45 degree of angles.
The dismountable press strip of described septum pellucidum sound-screen is connected by snap with fixed border.
Described fixation kit is corner brace and rivet.
