Further the mesh sheet that reinforcement is tied up is equipped with the pearlite concrete layer and concrete layer.Increase sound absorption
The intensity of plate, extends the service life of acoustic board.
Further the section of the acoustic board side plate is in 7 fonts, and protruding parts is towards acoustic board face plate center.Due to system
Backboard and side plate are first poured when making, panel, and composition used are being poured after backboard and side plate are molded and have some strength
Difference, the adhesion of panel and backboard, side plate is not strong, using being possible to come off due to shaking or exposing to the weather after a period of time,
Therefore set boss, panel closely to be blocked by boss after pouring on side plate, prevent from departing from.
Further the back side of the acoustic board and the thickness of side are identical, and positive thickness is more than or equal to the thickness at the back side
Degree.
Further the match ratio of concrete is the ratio of mud in concrete layer：0.28-0.30, shared river sand ratio is 1.3-
1.4, admixture ratio is 0.45-0.6, and described admixture is flyash, silica flour and water reducer, the flyash, silica flour and
The ratio of water reducer is 10:8:1, the ratio is the weight relative to cement.
Further pearlite concrete layer in perlite be particle diameter 1.0mm-2.0mm perforate perlite, perlite with
Cement, perforating agent, mineral fibres, hydrophober, water mixing are formed, and the proportioning of raw material is：Pearl in every cube of pearlite concrete
Rock mass product is 1.0-1.10m3, cement weight 275-340kg, drilling dosage is 1.6-2.0kg, and mineral fibres is 0.6-1.5kg,
Hydrophober is 6-9kg, and amount of water is 145-175kg.
Beneficial effect：Compared with prior art, the advantage of the invention is that：Improve most next piece suction in sound barrier combination
The structural strength of sound plate；Angle steel is placed, the compression strength and finished product percentage of head rice of acoustic board is improved, extends acoustic board and use the longevity
Life, reduces the workload that maintenance is changed.
