Abstract
The utility model discloses a sound barrier. The sound barrier comprises a body, wherein a group of cavities are arranged in the body; each cavity is communicated with the external air via a through hole; the maximum inner diameter of each cavity is greater than that of each through hole; and the surface, without the through holes, of the body is a veneering layer. Compared with the traditional sound barriers, the sound barrier disclosed by the utility model has the following advantages: the sound barrier has low cost and is fireproof, thus the sound barrier can replace fireproof plates; the sound barrier is convenient to install and can be directly pasted, dry-hung or connected by rivets and bolts; and the sound barrier has a good sound absorption effect, and as the density of the surface layer and the density of the sound absorption layer are inconsistent, better sound absorption and attenuation effects can be effectively achieved by adding invalid air holes in design.
Description
Technical field
The utility model relates to the constructional materials of a kind of isolated reduction sound transmission in the building materials, particularly a kind of sound barrier.
Background technology
Traditional sound barrier is generally cement products, and its shortcoming is that conduct oneself with dignity too heavy, difficult installation, acoustically effective is poor.The sound barrier that metal or organic glass class are arranged in recent years, their shortcoming are that fire endurance is poor, sound reflection is big, acoustically effective difference and cost cost are high.
Above various existing sound insulation materials all is to rely on thickness and density of material sound insulation, not concrete effectively sound-insulating structure.
The utility model content
The utility model purpose: the utility model technical problem to be solved is the deficiency to prior art, and a kind of sound barrier is provided.
In order to solve the problems of the technologies described above; The utility model discloses a kind of sound barrier; Comprise body, be provided with one group of cavity in the body, each cavity is communicated with outside air through a through hole; The maximum inner diameter of said cavity is greater than the maximum inner diameter of through hole, and the one side that through hole is not set on the said body is an overlay coating.
In the utility model, described cavity is any one in cylindrical cavity, circular cavity, oblong cavity and the square cavity.
In the utility model, said through hole is cylindrical hole or square through hole.
In the utility model, the one side that deviates from through hole on the said body is an overlay coating.
Beneficial effect: the described sound barrier of the utility model has the following advantages compared with prior art:
1, low, the fire prevention (alternative PLASTIC LAMINATED) of cost;
2, be convenient to install (can directly paste, cladding or riveting fasten connection);
3, acoustically effective good (because the close layer of face is inconsistent with absorbent treatment density, in the design the invalid pore of adding can effectively reach suction, the effect preferably of eliminating the noise).
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment the utility model is done specifying further, the above-mentioned and/or otherwise advantage of the utility model will become apparent.
Fig. 1 is the utility model cross-sectional view.
The specific embodiment
As shown in Figure 1; The utility model discloses a kind of sound barrier; Comprise body 1, be provided with one group of cavity 3 in the body 1, each cavity 3 is communicated with outside air through a through hole 2; The maximum inner diameter of said cavity 3 is greater than the maximum inner diameter of through hole 2, and the one side that deviates from through hole on the said body 1 is an overlay coating 4.Said cavity 3 is any one in cylindrical cavity, circular cavity, oblong cavity and the square cavity.Said through hole 2 is cylindrical hole or square through hole.Said body 1 is a polygon.Base material can be used the inorganic fire type, also can set composite decoration shape material, cement, metal etc.It between the said cavity low-density quieter material.
See that from the elevation of sound barrier it is divided into three layers: first floor is that via regions is an outer surface layer, for the high-intensity high-density inorganic material is made; The second layer is the cavity area layer, and its density can better act on absorption and shielding noise less than outer surface layer density, can be following any one low density material: inorganic plate, organic plates, glass bead plate, microporous foam cement board or CM foaming plate. The 3rd layer is overlay coating, is convenient to better be fixed on the building.The overlay coating material is for imitative wooden marble etc. or be cement based.
The preparation method of the utility model sound barrier can adopt following several kinds of modes: 1, punch forming; 2, casting mold moulding, perforate, composite molding.
Embodiment
Sound barrier in the present embodiment comprises square body 1, is provided with the cylindrical cavity 3 that one group of rectangular is arranged in the body 1, and each cavity 3 is communicated with outside air through a cylindrical hole 2.The internal diameter of said cavity 3 is greater than the internal diameter of through hole 2.The one side that deviates from through hole on the said body 1 is an overlay coating 4, and the overlay coating material is a marble.The base material of said body 1 is a cement.Cavity area layer between the said cavity is the low-density quieter material, adopts the foam cement plate.
The production method of the sound barrier of present embodiment is following, makes outer surface layer respectively, the cavity area layer, and stamp out cylindrical hole according to the size of through hole and cavity respectively, then successively with outer surface layer, cavity area layer and overlay coating gummed.
The utility model provides a kind of sound barrier; The method and the approach of concrete this technical scheme of realization are a lot, and the above only is the preferred implementation of the utility model, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.The all available prior art of each ingredient not clear and definite in the present embodiment realizes.
