Description
Technical field
The present invention relates to sound barrier technical fields, and more specifically, in particular to the shield plates of a kind of sound barrier produce work
Skill.
Background technique
Noise barrier refers to the wall structure to completely cut off noise being arranged to mitigate ambient noise.Soundproof wall
Referred to as sound barrier.It is inserted into a facility between sound source and recipient, Acoustic Wave Propagation is made to have a significant additional attenuation, thus
The influence of noise in certain area where decrease recipient, such facility are known as sound barrier.Be divided into traffic noise barrier,
Equipment noise decays noise barrier, industrial factory's circle noise barrier, is most using all types of sound barriers on highway and highway
Place.Noise barrier initially takes plate sound insulation, since noise can be propagated around around sound barrier continuation, so, now
It is required that sound barrier surface is cellular porous structure, the soundproof effect of sound barrier is promoted by sound absorption function.At present extensively
Application is plastic foamboard and polyurethane foam board, and sound-absorbing soundproof effect is very good, but since anti-uv-ray is poor, cruelly
It is exposed at aerial degradable weathering, service life is not grown.The metal foamings new material such as foamed aluminium developed in recent years, sound-absorbing sound insulation effect
Fruit is more preferable, and anti-uv-ray is strong, even if exposure is also not easy corrosion and ageing in the sky, service life is very long, but its manufacturing cost
It is too high, it is difficult to promote and apply.
The progress of air entrained concrete technology is that the low sound-absorbing barrier of development cost brings opportunity.It is known that aerating coagulation
Soil is with siliceous material (sand, flyash and containing silicon tailings etc.) and calcareous material (lime, cement) for primary raw material, and admixture is got angry
Agent (aluminium powder, SDS efficient aerating powder), made of the technical process such as ingredient, stirring, casting, precuring, cutting, steam pressure, maintenance
Light porous silicate product.Because it contains a large amount of uniform and tiny stomatas, except having, bulk density is light, thermal insulation property is high, sound insulation
Outside the good performance of effect, anti-uv-ray is also very strong, even if exposure is also not easy corrosion and ageing in the sky, service life is very
Long, manufacturing cost is low, but its foaming aperture is small, can only absorb high frequency noise, and after being cut into thin plate, resistance to fracture
It is greatly reduced.
Outside current top grade sound barrier does not require nothing more than sound insulation, sound-absorbing effect is had excellent performance, also require sound barrier that can prevent fires anti-
Ultraviolet light is anti-to fracture, and is not easy corrosion and ageing in the sky, durable, while manufacturing cost wants cheap.

Soil；
Concrete base paves, the barrier board concrete paves on mold according to regulation weight, forms bottom；
The addition of grid screen is laid with one layer of grid screen on the bottom, then re-lays barrier board concrete and forms half
Finished product shield plates；
Mold is sent into press by compacting, and press suppresses semi-finished product shield plates to obtain finished product shield plates；
Finished product shield plates are carried out steam curing by maintenance.
Preferably, the eps foam particle requirement partial size 1.5-4mm, not of uniform size, partial size 3mm is below short grained
30% is accounted for, the bulky grain of partial size 3mm or more accounts for 70%.
Preferably, specific step is as follows for the compacting:
After mold enters press, the positioning device of press is automatically positioned, and the pressure head downlink of press is close to compacting plane, then
It is converted into carrying out compacting movement at a slow speed；
It send after the completion of compacting to steam curing room and is conserved.
Preferably, the finished product shield plates are by natural temperature phase, temperature raising period, constant temperature phase and cooldown period maintenance, natural epidemic disaster in booth
The temperature for spending phase maintenance is environment temperature, and the time controls in 150min；
The temperature of temperature raising period maintenance increases 15 degrees Celsius every 1h, and until temperature reaches 50 degree, the time is controlled in 200min；
At 50 degrees Celsius, the time is controlled in 300min for the temperature control of thermostat；
Catathermal temperature declines 15 degrees Celsius every 1h, and until being down to room temperature, the time is controlled in 150min.
Preferably, the material of the enhancing grid screen uses one of wire or chemistry, plant, glass fibre or two
Kind or more braiding networking.
Preferably, after the finished product shield plates maintenance, the eps foam that plate surface is inlayed is ground off with kneader
Grain, to increase plate face porosity, loads onto frame finally to get sound-absorbing barrier plate finished product.
Compared with the prior art, the advantages of the present invention are as follows:
Shield plates simple production process of the present invention, obtained shield plates structural strength is high, and due to using coagulation simultaneously
Soil foams and adds big partial size foam beads technique, and not only lightweight, fire prevention, soundproof effect are good, but also due to plate surface hole
Rate is high, aperture is various, is conducive to the noise for absorbing various frequencies, so sound absorption qualities are excellent.
This sound barrier plate combines enhancing grid screen muscles and bones structure by substrate of concrete, and not only intensity is high, fold resistance
Can be good, it is durable, and ultraviolet radiation resisting can be supported, and it is not afraid of and exposes to wind and rain, the not degradable aging under solar exposure.
