Technical field
The utility model relates to road engineering sound insulation and noise reduction technical fields, and in particular to one kind has sound absorption and sound insulation function
Combined type sound barrier.
Background technique
Highway, railway, rail traffic route by the noise-sensitives such as city neighborhood, hospital, school and office building region,
It needs that sound barrier is set as needed in route two sides (or side), by the sound absorption of sound barrier, sound insulation function, makes vehicular traffic
Noise decays to defined magnitude or less when reaching sensitizing range.
Existing common noise barrier structure mainly has reinforced concrete wall, steel plate, light-alloy plate, acrylic board, PC plate etc..
Reinforced concrete wall sound insulation effect is good, but thickness and from great, and occupied space is more, and use scope is limited；Steel plate also have compared with
Good sound insulation effect, but bigger than normal, easy-to-rust of being self-possessed, higher cost；The light alloys plate sound insulation effect such as aluminium, magnesium is preferable, from heavy and light,
But cost is very high；Acrylic board sound insulation effect is preferable, and transparent landscape is good, but higher cost；PC plate sound insulation effect is fine, transparent scape
It sees, but cost is very high.In addition, pay close attention in existing sound barrier product in sound insulation effect, sound absorption and sound insulation effect are taken into account
Product is less.The only sound barrier of sound insulation effect can control acoustic environment in the sensitizing range at sound barrier rear and reach and allows to want
It asks, but due to the reflection effect on audio frequency barrier surface in the route space in front of sound barrier, noise source is superimposed with reflection noise, can make
It obtains passenger's noise circumstance in the vehicles to deteriorate, adverse effect may cause to passenger's body and mind.
Therefore, to solve the above-mentioned problems, need to design a kind of at low cost, and sound absorption and sound insulation function can be had both
Sound barrier.
Utility model content
In view of this, the present invention provides a kind of with the combined type sound barrier to absorb sound with sound insulation function.
The combined type sound barrier with sound absorption and sound insulation function provided by the utility model, it is characterised in that: including sound insulation
Layer and absorbent treatment, the sound insulating layer fitting is set to the one side of absorbent treatment, and wraps to the another side of absorbent treatment and form bound edge；Institute
Stating absorbent treatment is plastic bonding light-weight aggregate layer, and the light-weight aggregate layer is embedded with grid；The sound insulating layer is fiber-reinforced resin layer.
Further, the absorbent treatment and sound insulating layer pass through bonding connection.
Further, the grid is that fiber-reinforced resin grid, metallic grid or steel mould grid.
Further, the resin uses unsaturated polyester resin, epoxy resin and/or phenolic resin.
Further, the fiber uses glass fibre, aramid fiber, carbon fiber or basalt fibre.
The utility model has the beneficial effects that combined type sound barrier provided by the utility model, can pass through in traffic route
When noise-sensitive region, within the specified scope by acoustic environment index of correlation control in the sensitizing range of sound barrier rear, and effectively drop
The noise reflection of barrier front surface in a low voice improves the acoustic environment of traffic route space interior.Simultaneously as using reasonable material
Combination and structural form, combined type sound barrier provided by the utility model have from heavy and light, intensity is high, rigidity is big, energy-absorbing anti-impact,
The advantages of weather-proof anti-corrosion, cost is relatively low.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the main view of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
In figure: 1, plastic bonding light-weight aggregate layer, 2, grid, 3, fiber-reinforced resin layer, 4, bound edge.
Specific embodiment
Fig. 1 is the main view of the utility model, and Fig. 2 is the cross-sectional view of the utility model；As shown, the present embodiment provides
The combined type sound barrier with sound absorption and sound insulation function, including sound insulating layer and absorbent treatment, the sound insulating layer fitting is set to suction
The one side of sound layer, and wrap to the another side of absorbent treatment and form bound edge；The absorbent treatment is plastic bonding light-weight aggregate layer, and this is light
Aggregate lift is embedded with grid；The sound insulating layer is fiber-reinforced resin layer；In the present embodiment, by plastic bonding light-weight aggregate layer with
Fiber-reinforced resin layer is combined, and has been prepared suction-every combined type sound barrier, can have been passed through noise sensitive area in traffic route
When domain, within the specified scope by acoustic environment index of correlation control in the sensitizing range of sound barrier rear, and before sound barrier is effectively reduced
The noise reflection on surface improves the acoustic environment of traffic route space interior；And grid is embedded in plastic bonding light-weight aggregate layer, simultaneously
So that fiber-reinforced resin layer packet is had mercy on plastic bonding light-weight aggregate layer can be to resin in plastic bonding light-weight aggregate layer surface formation bound edge
Cementing light-weight aggregate layer carries out the reinforcement of intensity, rigidity and globality etc., and prevents noise in plastic bonding light-weight aggregate layer week
Avris leakage diverging.Meanwhile using plastic bonding light-weight aggregate layer as absorbent treatment, using fiber-reinforced resin layer as sound insulating layer,
At low cost, sound absorption and sound insulation effect are excellent.By using reasonable combination of materials and structural form in the present embodiment, finally obtain
From heavy and light, intensity is high, rigidity is big, energy-absorbing anti-impact, weather-proof anti-corrosion, the lower-cost combined type with sound absorption and sound insulation function
