Abstract
The utility model provides a light high-efficient cement sound-insulation and sound-absorption plate. The sound-insulation and sound-absorption plate is a multi-hole composite section material cement plate, and the cross section of the sound-insulation and sound-absorption plate is in a checkered shape; a water proof and sound-absorption material is filled in the multi-hole of the composite section material cement plate, one side plate surface of the sound-insulation and sound-absorption plate is punched with sound-absorption through holes and the hole opening ratio is 15-30 %. The beneficial effects are that the sound-insulation and sound-absorption plate has high compactness, high hardness, high hole ratio, excellent bending and shock resistant performances, and due to many holes, the plate is caused to reduce self weight, and thus light high strength is really realized and the sound-insulation coefficient S T C is 40 dB. The installation is convenient, and the construction is not limited by climate. The range of application is broad, and the light high-efficient cement sound-insulation and sound-absorption plate can be used as indoor decoration as well as outdoor architecture, and the functions of beauty and noise reduction are obtained. The light high-efficient cement sound-insulation and sound-absorption plate is applicable to the noise treatment in the traffic fields such as expressways, light rails, railways, culverts, tunnels and various industries, factory buildings, workshops, theaters, residential districts, etc. The acid and alkali erosion resistant performance is good, the randomness of decoration and spray coating is strong, the cost is low and the anti-theft performance is high.
Description
Technical field
The utility model relates to a kind of sound barrier that reduces noise, particularly a kind of efficient and light weight cement Felt.
Background technology
Along with the urban road construction develop rapidly, noise pollution is on the rise, and therefore its improvement work has more and more been caused people's attention.Most now effects that adopt the method that sound barrier is set to reach noise reduction, and sound barrier adopts metal material mostly, it is easy to generate corrosion, and antiseptic property is poor, has shortened service life, causes a large amount of maintenance works, has strengthened cost.
Summary of the invention
In order to solve the deficiency that exists in the above-mentioned technology, the purpose of this utility model provides a kind of efficient and light weight cement Felt that improves decay resistance, increases the service life.
For achieving the above object, the technical solution adopted in the utility model provides a kind of efficient and light weight cement Felt, described Felt is the cement board of porous composite material, its cross section is the grid shape, in the cement board porous of composite material, fill the waterproof sound absorption material, and on the side plate face of Felt, being installed with the sound absorption open-work, percent opening is 15-30%.
The hole shape of wearing the sound absorption open-work on the side plate face of Felt has circle, rectangle.
The waterproof sound absorption material of filling in the cement board porous of composite material is centrifugally glass-wool, rock wool, mineral wool material, its surface parcel alkali-free hydrophobic cloth or mylar.
Efficient and light weight cement Felt of the present utility model has the following advantages:
1, high strength, high compact, high rigidity, high hole rate have fabulous bending, shock resistance, and because multiple hole, make the sheet material weight reduction, thus real realization high-strength light.
2, the density backboard has strengthened whole defening effect, and its sound absorption reduction coefficient NRC is between 0.75-0.90, and sound insulation factor STC is 40dB.
3, simple and easy, be convenient to install, and construction is not restricted by weather.
4, the scope of application is wide, both can make outdoor architecture, also can make interior decoration, reaches the effect of not only attractive in appearance but also noise reduction.Be applicable to the noise abatement in field of traffic such as through street, light rail, railway, culvert, tunnel and fields such as various industry, factory building, workshop and theater, residential quarters.
5, has the performance that weatherability, moisture resistance are wet, weather proof, acid and alkali-resistance corrodes.
6, attractive in appearance plastic, decorate the spraying randomness by force.
7, cost is low, theftproof is strong.

The specific embodiment
Reach embodiment in conjunction with the accompanying drawings efficient and light weight cement Felt of the present utility model is illustrated, but be not limited only to described embodiment.
Shown in Fig. 1,2,3,4, with efficient and light weight cement Felt is that the sound barrier of unit sheet material is an example, its structure is to be support body with H steel column or concrete post, is plugged with the identical efficient and light weight cement Felt of polylith on support body, is equipped with various connectors and is assembled into sound barrier.
Efficient and light weight cement Felt 3 is the porous section bar, adopting moulding such as powdered adhesive gel material such as cement, stone flour and flyash and aggregate, fiber, fluidizer, early strength admixture to strengthen additive is raw material, mixed together extrusion modling, its cross section are the composite material cement board of grid shape.Then, on the one side of profile plate, have open-work 1, communicate, and in the section bar porous, fill waterproof sound absorption material 2 with hollow porous in the section bar.
The open-work pass of being worn on the plate face of unit Felt has multiple hole shapes such as circular apertures, rectangle hole, and percent opening is at 15-30%.
The waterproof sound absorption material 2 of filling in the porous of composite material is centrifugally glass-wool, rock wool, mineral wool material, its surface parcel alkali-free hydrophobic cloth or mylar.
Be the sound barrier of unit board making for example with efficient and light weight cement Felt, be earlier the support body of H steel column or the concrete post mode with bolt or welding to be fixed on the basis, then Felt is inserted in the groove of support body, with other connector sound barrier is connected and fixing with the spring jig.
