Abstract
The invention discloses a novel light high-strength nonmetal sound barrier which comprises concrete face plates, a sound absorbing layer, concrete back plates and concrete side plates provided with male and female grooves corresponding in size. The sound absorbing layer is arranged between the concrete face plates and the concrete face plates, and the concrete side plates arranged on the top face and the bottom face the sound barrier. The concrete face plates are provided with sound absorbing holes. The novel light high-strength nonmetal sound barrier can be formed by utilizing excellent performance of reinforced concrete in one time, and the formed sound barrier has the advantages of having wider-frequency noise reduction performance and being high in strength, excellent in durable performance, simple in process, convenient to operate, low in cost and the like.
Description
Technical field
The invention belongs to sound insulation materials field, particularly relate to a kind of Novel light high-strength non-metal sound barrier.
Background technology
Along with the continuous enhancing of people's environmental consciousness, problem of noise pollution more and more comes into one's own.In recent years, the fast development of building due to high-speed railway, speedway, urban elevated road and urban light rail and the sharply increase of urban automobile quantity, traffic noise problem is on the rise, become affect people's lives the most seriously, the most widely pollute one of.In the measure of various control traffic pollution, sound barrier is set up to be a kind of effective ways.
Existing sound barrier mainly includes machine sound barrier, metallic sound barrier and inorganic sound barrier three class.Although organic sound barrier and metallic sound barrier have simple installation, be convenient to maintenance and can the advantage such as scale manufacturing, its cost is high, poor with coordination of landscape, corrosion resistance requires that high shortcoming is also clearly.Inorganic sound barrier has corrosion-resistant, pollution-free, low cost and other advantages, but there is the low defect of sound absorbing capabilities in the coagulation great soil group that in existing inorganic sound barrier, intensity is high, and the high pearlite slab of sound absorbing capabilities exists the defect of strength deficiency, therefore the contradiction coordinated between sound barrier intensity and sound absorbing capabilities becomes urgent problem.
Summary of the invention
For solving the problems of the technologies described above, the invention provides that a kind of intensity is high, sound absorbing capabilities good, production technology is simple, the high-strength light non-metal sound barrier of operation and easy construction.
For achieving the above object, the present invention is achieved by the following technical solutions.
A kind of Novel light high-strength non-metal sound barrier, comprises concrete slab, absorbent treatment, the concrete side plate of the male and female groove that concrete back plate is corresponding with being provided with size; Between concrete slab and concrete back plate, arrange absorbent treatment, described concrete side plate is arranged on sound barrier end face and bottom surface; Concrete slab is provided with sound-absorbing hole.Concrete slab, concrete back plate and concrete side plate form sound barrier exterior contour, make it have enough intensity; Inner filling absorbent treatment, concrete slab is provided with sound-absorbing hole, and noise enters sound barrier inside by sound-absorbing hole, is reached the effect of noise reduction by the absorption of absorbent treatment.
The pass of described sound-absorbing hole is one or more in circular hole, strip hole or diamond hole, and the arrangement mode of sound-absorbing hole is in line or the wrong row of plum blossom, and the perforated percentage of concrete slab is 15-25%.The difference of pass and arrangement mode change have Different Effects to the effect of noise reduction, also considerable influence is had to sound barrier outward appearance, the perforated percentage of concrete slab can not too high can not be too low, the too high bulk strength affecting sound barrier of perforated percentage, the too low noise reduction affecting sound barrier of perforated percentage.
Described absorbent treatment comprises low frequency, intermediate frequency and high-frequency sound-absorbing material, and namely the inorfil such as centrifugally glass-wool or rock wool class sound absorption material and the non-fiber such as pearlite slab or veneer class sound absorption material combine.The noise of different-waveband can be absorbed.
Arrange waterproofing course between described concrete slab and absorbent treatment, described waterproofing course is hydrophobic glass cloth or non-woven fabrics.After sound absorption material makes moist, acoustically effective can obviously decline, and humidity can corrode sound absorption material for a long time, can effectively prevent rainwater from entering sound barrier inside from sound-absorbing hole after arranging waterproofing course.
Some transverse directions and longitudinal reinforcing bar is provided with in described concrete slab and backboard.The bulk strength of sound barrier is further strengthened after adding reinforcing bar.
Beneficial effect: compared with prior art, the invention has the advantages that: form composite construction by the humidification of steel concrete perforated panel, backboard and side plate and built-in water and absorbent treatment, by the premium properties one-shot forming of steel concrete, and the anti-acoustic capability of the sound barrier tool wider frequency rate formed, the advantage such as intensity is high, excellent durability, technique are simple, easy to operate, with low cost.
