Abstract
The utility model is a composite acoustic board made of cement and wood pieces; the composite acoustic board can be used to prevent noise from polluting environments, and belongs to the field of special construction materials; the utility model is compressed to form with cement, wood pieces and additives; the top of the base plate is arranged with an acoustic board with bar-shaped bosses; the bar-shaped bosses include such shapes as sharp wedge, semi-circle and trapezoid and etc; the surroundings of the board can be arranged with raised edges. The board has advantages of simple application and installation, moisture resistance, mildew resistance, weathering resistance, resisting freezing and thawing, long service life and perfect machining performances.
Description
(1) technical field: the utility model relates to a kind of cement sawdust sound-absorbing composite board, is used for the occasion that speedway, railway, large-sized workshop etc. need prevent noise pollution, belongs to the sound absorption material technical field of extraordinary building materials.
(2) background technology: aspect sound absorption material, generally using has 3 kinds at present, and first kind is color steel sheet, the sound absorbing member that aluminium sheet is made will often be safeguarded, mopping within 10 years application life during use, enamelled coating easily wears out, comes off, causes the corrosion of metal sheet face, breakage, so that within 10 years, just can not use, second kind is organic foamed ceramics, adding curing compound with polystyrene makes, very crisp, easily aging, cause secondary pollution after the fragmentation.The third is the roast acoustical board that becomes with the mineral roast with clay, and the plate face has only below 500 * 500mm, and moulding is also difficult, and grain is fallen on the surface at a touch, bad splicing, installation.Cost is also high, about 400 yuan/M
2
(3) summary of the invention: the purpose of this utility model is the weak point at above-mentioned sound absorption material, and a kind of cement is provided, and the wood chip sound-absorbing composite board to satisfy the sound absorption material that is suitable for of current urgent need, solves the current noise pollution problem that becomes increasingly conspicuous.
Structure of the present utility model is the substrate (1) that adds Admixture mixing compression moulding with cement and wood chip shown in Fig. 1-5, and there is the acoustical board of strip projection (2) top.Strip projection (2) can be made into wedgelike strip projection, as (2a) among Fig. 2, or makes semicircle strip projection, as (2b) among Fig. 3, or makes trapezoidal strip projection, as (2c) among Fig. 4 and other cross sectional shape.Can make ledge (3) around the plate, see shown in Figure 5.
This product can be applicable to speedway, high-speed railway, power station, hospital, school, sports palace, subway access, industry, civilian construction.
Its advantage be use and install simple, but prefabricated units humidity, go mouldy, weather resistance, freeze thawing resistance, long service life does not need frequent maintenance, impact resistance has good processing properties.Appearance and modeling can be diversified, and can reach 20 years application life.

Fig. 2 is the drawing in side sectional elevation of Fig. 1
Fig. 3 is 1 of embodiment of the present utility model
Fig. 4 is 2 of embodiment of the present utility model
Fig. 5 is 3 of embodiment of the present utility model
(5) specific embodiment:
The utility model is cement available silicon acid salt cement when implementing, sulphate aluminium cement etc., wood chip can be used wood wool, woodworking mill's leftover bits and pieces such as spile, particle diameter are 1-5cm, cement, wood chip cooperates by proper proportion, add extraordinary Admixture, the effect of this Admixture is that wood chip surface mineralising is handled, energy waterproof, fire prevention and anti-going mouldy.And the increase adhesion stress, compound is stirred, according to the requirement of product, select suitable mold, or semicircle strip projection or wedge shape or trapezoidal, whether product structures such as ledge are arranged all around, on hydraulic press, be pressed into acoustical board.
Claims (3)
1. cement, the wood chip sound-absorbing composite board is characterized in that adding with cement and wood chip the substrate (1) of Admixture mixing compression moulding, there is the acoustical board of strip projection the top.
2. cement according to claim 1, the wood chip sound-absorbing composite board is characterized in that described strip projection (2), can be made into wedgelike projection (2a), half-circle projection (2b), trapezoidal protrusion (2c).
3. cement according to claim 1, wood chip acoustical board, it is characterized in that ledge (3) is arranged around the described acoustical board.
