Abstract
The utility model belongs to building materials sound absorption material technical field, relates to a kind of cement based sound-absorbing composite board, and for speedway, the noise barriers such as urban road absorb field of engineering technology.This acoustical board panel arranges conical sound-absorbing hole, circular cone sound-absorbing hole is small structure design in outer macropore, the upper and lower bilateral symmetry of sound absorption panel establishes groove (3) and tongue (2), and the groove of adjacent two pieces of sound absorption panels is corresponding with tongue, is fixed by sound absorption panel.The utility model structure is simple, and simple installation, effectively can prevent rain penetration, reduces rainwater washing away and corroding acoustical board material, substantially prolongs the application life of acoustical board.
Description
Technical field
The utility model belongs to building materials sound absorption material technical field, relates to a kind of cementitious composite acoustical board, absorbs field of engineering technology for noise barriers such as speedway, high-speed railway, urban roads.
Background technology
At present along with the continuous progress of society, the continuous increase of transportation and communication, more and more serious to the noise pollution of speedway, high-speed railway, municipal highway both sides resident, all require in therefore road construction process of construction to arrange noise barrier.Sound-deadening and noise-reducing sound insulating panel is road sound barrier again, high speed acoustical board, noise barrier etc.; Be made up of insulated column, connecting piece and securing member.Acoustic screen is made up of the end socket at post, noise reduction panel, filling damping material and upper and lower two ends.Noise major part on speedway is entered by noise reduction panel, is absorbed by sound-absorbing packing material with the requirement reaching noise environmental protection.Current domestic existing cement based sound-absorbing composite board divides blinds shape and strip two kinds, and in use acoustical board is often subject to rainwash, and blinds shape and elongate holes are all easily by rain penetration, and easily aging, application life reduces greatly.The plating runner plate that existing market is sold or aluminium sheet, surface is through punching, and the plane sound absorbing member of spray treatment, structure, function singleness, cost is high.
Utility model content
For solving the deficiency that above-mentioned prior art exists, it is simple that the utility model aims to provide a kind of structure, good water-proof effect, long service life, and structure and mounting process simply close acoustical board for the high-strength cement base ceramsite concrete light-weight of highway noise pollution plot.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of cement based sound-absorbing composite board, comprises sound absorption panel, and sound absorption panel arranges conical sound-absorbing hole 1, and panel is sound-absorbing hole macropore 12 towards noise source one end, is sound-absorbing hole aperture 11 to panel inner opposite end; The upper and lower bilateral symmetry of described sound absorption panel is provided with groove 3 and protruding 2, and the groove of adjacent two pieces of sound absorption panels is corresponding with projection, is fixed by sound absorption panel.
As concrete scheme, the hole diameter of described conical sound-absorbing hole 1 is the half of diameter macropores.
The utility model changes shutter type and strip sound-absorbing hole structure into cone-shaped hole structure by the basis of conventional sound-absorbing panel, be sound-absorbing hole macropore 12 towards noise source one end, be sound-absorbing hole aperture 11 to panel inner opposite end, this design effectively can prevent rain penetration, reduce rainwater washing away and corroding acoustical board material, substantially prolongs the application life of acoustical board.
The utility model is respectively arranged with groove and projection at the upper and lower surface of acoustical board simultaneously, and the mutual clamping of adjacent acoustical board two trench structure is fixed acoustical board, makes acoustical board structure installment simpler.
For obtaining further effect, the sound-absorbing hole on acoustical board is arranged to the little structure of outer imperial palace, through strict calculating, diameter of bore is arranged to 1/2nd of outer space diameter simultaneously, ensure that muffler plate can prevent rain penetration while effectively absorbing noise, the two is taken into account, and reaches optimum result of use.
Accompanying drawing explanation
Fig. 1 the utility model structural representation;
Fig. 2 the utility model sound-absorbing hole structure chart;
Fig. 3 the utility model groove and protruding section amplification effect schematic diagram.
In figure, the implication of each mark is: 1-sound-absorbing hole, and 2-is protruding, 3-groove, 11-sound-absorbing hole aperture, 12-sound-absorbing hole macropore.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described further; it is to be noted that following embodiment is all indicative explainations that the mode that exemplifies is done the utility model; but protection domain of the present utility model is not limited in this, all those skilled in the art all fall into protection domain of the present utility model with spirit of the present utility model to the replacement of the equivalence that the utility model does.
Embodiment 1
A kind of cement based sound-absorbing composite board, adopts 600 grades of leaf rock ceramic granules to make aggregate, and 700 grades of pottery sand are prepared from as fines, and its structure as shown in Figure 1.Sound absorption panel arranges conical sound-absorbing hole 1, and panel is sound-absorbing hole macropore 12 towards noise source one end, is sound-absorbing hole aperture 11, as shown in Figure 2 to panel inner opposite end.The upper and lower bilateral symmetry of sound absorption panel is provided with groove 3 and protruding 2, and as shown in Figure 3, the groove of adjacent two pieces of sound absorption panels is corresponding with projection, and protruding lug boss snaps in groove shrinkage pool, is fixed by upper and lower two pieces of sound absorption panels.
Embodiment 2
A kind of cement based sound-absorbing composite board, adopts 600 grades of leaf rock ceramic granules to make aggregate, and 700 grades of pottery sand are prepared from as fines, and its structure as shown in Figure 1.Sound absorption panel arranges conical sound-absorbing hole 1, panel is sound-absorbing hole macropore 12 towards noise source one end, be sound-absorbing hole aperture 11 to panel inner opposite end, as shown in Figure 2, for ensureing optimum soundproof effect and avoiding acoustical board to be soaked by rainwater, reach optimum waterproof effect, make the hole diameter of conical sound-absorbing hole 1 be the half of diameter macropores.The upper and lower bilateral symmetry of sound absorption panel is provided with groove 3 and protruding 2, and as shown in Figure 3, the groove of adjacent two pieces of sound absorption panels is corresponding with projection, and protruding 2 lug bosses snap in groove shrinkage pool, is fixed by upper and lower two pieces of sound absorption panels.
