Abstract
The utility model provides a combined type sound absorption decorative screen, comprising four portions, a middle frame, a flame-proof sound absorbing material layer, a flame-proof decorative fabric layer and an edge frame. A middle layer is the frame, a right outer layer and a left outer layer are the sound absorbing material layers, the outer sides of the flame-proof sound absorbing materials are matched with flame-proof decorative fabric, and the edge frame is made from the composite materials of plastic, wood, steel plate, aluminium alloy, glass steel, stainless steel, products made of bamboo, etc. The flame-proof sound absorbing materials comprise organic inorganic fiber, plastic foam, polyurethane foam, glass fiber, glass cotton, glass silk, mineral cotton, sponge, etc. The utility model is a high-efficient sound absorption screen which is made from various materials according to certain technical requirements. The combined type sound absorption decorative screen has good ornamental function, water proof, corrosion proof, moth proof, flame proof, easy maintenance and repair, convenient mount and repair, superior quality, moderate price, green environment protecting, nondestructive for human body health, fire proof, security, stable and reliable sound absorptive performance for a long time, wide sound absorption band and obvious middle and low frequency sound absorption effect.
Description
Technical field:
The utility model relates to a kind of decoration sound absorption screen of standard, belongs to International Classification of Patents A47G5/00 screen, secondary classification E04B1/86 " board-like Sound-absorbing member " technical field.
Background technology:
Existing screen generally only has decoration function and compartmentation, and does not possess sound-absorbing effect.If reach sound-absorbing effect, also must additionally add the sound-absorbing facility.Otherwise the noise problem such as office and public place is difficult to solve.How reaching in the beautifying and decorating indoor and outdoor spaces, also can reach the sound absorption requirement, is the big problem that we face.
Summary of the invention:
The purpose of this utility model provides a kind of beautifying and decorating effect that both had, combined ornamental sound absorption screen that again can absorption of noise.
The utility model by the following technical solutions.
A kind of combined ornamental sound absorption screen, constitute by middle skeleton (1), sound-absorbing material layer (2), the decorative cover bed of material (3), frame (4), its hierarchical structure: its hierarchical structure: carry out intermedium rack-layer (1) earlier, add fire-retardant sound-absorbing material layer (2) in the skeleton outside and then the decorative cover bed of material (3) is attached to the sound absorption material outside, at last frame (4) is combined in one with it.
Skeleton (1) is made by composite materials such as timber, plastic-steel, plastics, glass fiber reinforced plastic, steel, bamboo products in the middle of described.
The flow resistance of fire-retardant sound absorption material is 40-150 Newton-second rice m
2, handkerchief rice second m
2Between.
Fire-retardant sound absorption material comprises organic inorfil, plastic foam, polyurethane foam, glass fiber, glass wool, glass fiber, mineral wool, sponge etc.
Decorative fabric belongs to the textile with fire resistance.
Frame is made by composite materials such as plastics, timber, steel plate, aluminium alloys, glass fiber reinforced plastic, stainless steel, bamboo products.
Combined ornamental sound absorption screen of the present utility model is middle skeleton, fire-retardant sound absorption material, frame and the combination of extraneous adornment lining four parts of being made according to certain technical requirements by multiple material, and the efficient decoration sound absorption screen of making.Keep good decorative property, waterproof, corrosion resistant is mothproof, and is fire-retardant, is easy to maintenance, and installation and maintenance are convenient, and quality is excellent, moderate cost, environmental protection is to the health not damaged.Have plurality of advantages such as the feature of environmental protection, functional, safety (fire prevention), ornamental and economy.Be the acoustic construction design according to science, it is controlled to have the sound absorption material performance, the sound absorbing capabilities long-term stability, and acoustic frequency bandwidth, especially the medium and low frequency acoustically effective is obvious.Satisfying with this having sound absorption to require and noise control in modern architecture.Extensive market, less investment, instant effect, economy and society remarkable benefit.
Description of drawings:
Fig. 1 is the structural representation of the utility model combined ornamental sound absorption screen.
Among the figure: 1, middle skeleton, 2, fire-retardant sound-absorbing material layer, 3, the flame-retardant decorative precoat, 4, frame.
The specific embodiment:
