Abstract
The utility model discloses a kind of novel inorganic sound barrier, be made up of multiple fixed frame and the sound absorption backboard being positioned at fixed frame, described sound absorption backboard is made up of base plate, steel wire grid and the sound absorbing module be integrally formed on base plate, base plate and sound absorbing module are fixed together by cementing agent, described base plate offers sound-absorbing hole, be placed with sound absorption material object in described sound-absorbing hole, its arranged outside has steel wire grid and sound absorbing module sealing.The utility model have employed inorganic porous sound absorption material as acoustical board, solves the existing problem brought because of concrete slab or metallic sound barrier heaviness; Both sound absorbing module and base plate are fixed on an entirety by cementing agent, solve the trouble that failure in a long time object comes off; The setting of steel wire grid decreases interface shrinkage, can be secured entirely in sound-absorbing hole by sound absorption material, not only increase the service life of sound absorption material, and have better acoustically effective.
Description
Technical field
The utility model belongs to a kind of traffic acoustic damping materials, is specifically related to a kind of novel inorganic sound barrier.
Background technology
The fourth-largest environment pollution during noise pollution after water pollutions, atmosphere pollution and solid pollution, traffic noise is then noise pollution the most serious.And along with the raising of the progress of society, the development in city and living standards of the people, urban traffic becomes requisite part in life.Building up of a large amount of high ferros, urban light rail, speedway, the convenience brought, but a lot of expressway is through dense population areas simultaneously, noise will inevitably be brought, very large impact is brought on the live and work of the people, so set up some antinoise barrier shields to be absolutely necessary on side, expressway.
Usually produce between source and noise pollution sensitizing range at noise and acoustical board is set, for intercepting or absorbing noise, reduce sensitizing range noise pollution.General existing sound absorption shield often acoustical board and base plate separates, just acoustical board is arranged on base plate when by the time constructing, not only increase the load of engineering time, the thick and heavy increase bridge of shield like this, affect construction speed, the sound absorption material of filling in metallic sound barrier easily comes off rotten rotten, affects soundproof effect.
Utility model content
The technical problems to be solved in the utility model there are provided a kind of novel inorganic sound barrier, and this sound barrier can integrated molding, decreases the worry that secondary is assembled; Inorganic materials replaces metallic sound barrier, decreases later maintenance; Sound absorption cotton is sealed in inorganic material inside completely, adds its service life.
In order to solve the problems of the technologies described above, the utility model realizes in the following manner:
A kind of novel inorganic sound barrier, be made up of multiple fixed frame and the sound absorption backboard being positioned at fixed frame, described sound absorption backboard is made up of base plate, steel wire grid and the sound absorbing module be integrally formed on base plate, base plate and sound absorbing module are fixed together by cementing agent, described base plate offers sound-absorbing hole, be placed with sound absorption material object in described sound-absorbing hole, its arranged outside has steel wire grid and sound absorbing module sealing.
Described sound-absorbing hole is evenly distributed or uneven arrangement, and the aperture of sound-absorbing hole is 5 ~ 50mm, and its hole depth is 10 ~ 100mm.
Described sound absorption material object is that sound absorption is cotton, glass wool or rock wool one or more.
The material of described base plate adopts inorganic porous material, and sound absorbing module is inorganic sound absorption material, and its surface is ripple kerve shape.
Compared with prior art, the beneficial effect that the utility model has: the utility model have employed inorganic porous sound absorption material as acoustical board, solves the existing problem brought because of concrete slab or metallic sound barrier heaviness; Both sound absorbing module and base plate are fixed on an entirety by cementing agent, solve the trouble that failure in a long time object comes off; The setting of steel wire grid decreases interface shrinkage, can be secured entirely in sound-absorbing hole by sound absorption material, not only increase the service life of sound absorption material, and have better acoustically effective.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed description of the invention of the present utility model is described in further detail.
As shown in Fig. 1-3, a kind of novel inorganic sound barrier, be made up of multiple fixed frame and the sound absorption backboard being positioned at fixed frame, described sound absorption backboard is made up of base plate 3, steel wire grid 2 and the sound absorbing module 1 be integrally formed on base plate, base plate 3 and sound absorbing module 1 are fixed together by cementing agent, described base plate 3 offers sound-absorbing hole 4, sound absorption material object is placed with in described sound-absorbing hole, its arranged outside has steel wire grid and sound absorbing module sealing, the aperture of described sound-absorbing hole is 5 ~ 50mm, and its hole depth is 10 ~ 100mm.
Sound absorption material object is that sound absorption is cotton, glass wool or rock wool one or more, the material of described base plate adopts inorganic porous material, and sound absorbing module is inorganic sound absorption material, and its surface is ripple kerve shape.
The above is only embodiment of the present utility model; again state; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also carry out some improvement to the utility model, these improvement are also listed in the protection domain of the utility model claim.
