Abstract
The utility model discloses a metal roof rain noise control structure which comprises a metal roof and a sound absorption material layer arranged on the inner side of the metal roof. A damping shock absorption layer is arranged between the metal roof and the sound absorption material layer, the upper surface of the damping shock absorption layer is adhered to the inner side of the metal roof, and the sound absorption material layer is adhered to the lower surface of the damping shock absorption layer. The rain noises control structure is provided with the damping shock absorption layer so as to be good in damping shock absorption effect, and the sound absorption material layer can effectively reduce indoor noise in torrential rain weather to about 30 decibels. The insulated metal roof and the sound absorption material layer are directly connected so as to effectively protect quick aging of the sound absorption material layer caused by heat transferred by the metal roof from the sound absorption layer in high temperature weather. The rain noise control structure is simple in structure, good in sound insulation, easy to construct and low in cost.
Description
Technical field
The utility model relates to architectural construction, particularly a kind of rain noise of metal Roof control structure.
Background technology
The architect is when the design building scheme; usually can use the metal Roof structure; because roof structure can be realized any moulding, with the intention of performance individual character uniqueness, yet the building of metal roof but allows the people feel to perplex very much when the rainy day; heavy rain can produce very large impact sound to metal roof; according to measuring statistics, in the metal roof building without any soundproof measures, during rainstorm weather; indoor noise is generally about 80 decibels, and human body health, work and life are all had a significant impact.
At present, the method of sound insulation that generally adopts in the row is the sound-absorbing material layer of or inorganic fibre mat organic in the spraying of metal roof internal layer, the method can be effectively with about indoor reducing noise to 50 decibel, but this also can not satisfy people far away environment is quietly pursued, and metal heat-conducting is fast, the organic/inorganic fibrage easy ageing failure that is heated for a long time, even come off.
Summary of the invention
The utility model purpose is to address the above problem, and a kind of rain noise control structure is provided, and it has high defening effect, can be applicable to the demanding building that insulates against sound.
For solving above technical problem, the technical solution of the utility model is: a kind of rain noise control structure, comprise metal Roof and the sound-absorbing material layer that is arranged on described metal Roof medial surface, also be provided with the damping shock absorption layer between described metal Roof and the described sound-absorbing material layer.
Wherein, described damping shock absorption layer upper surface and described metal Roof medial surface are bonding, and described sound-absorbing material layer is bonded in described damping shock absorption layer soffit.
Preferential, described sound-absorbing material layer is inorfil sprayed coating or flame proofing organic fibre sprayed coating.Organic fiber is natural plant fibre, and softness is rich in toughness, and frangibility does not spray through can be used as acoutic fibre board after the flame treatment.
Preferential, described damping shock absorption layer is to make beam by rubber or Plastic expanded material, can be homogenous material, also can be the composite material that multiple material is made.
The beneficial effects of the utility model are, are provided with the damping shock absorption layer between metal Roof and sound-absorbing material layer, and its damping shock absorption is effective, in conjunction with sound-absorbing material layer can be effectively with about reducing noise to 30 indoor under the rainstorm weather decibel; And isolated metal Roof directly connects with sound-absorbing material layer, protected effectively that the direct transferring heat of metal Roof gives sound-absorbing material layer and causes the aging rapidly of sound-absorbing material layer under the hot weather.This rain noise control structural texture is simple, and defening effect is good, and construction easily, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further detailed.
As shown in Figure 1, a kind of rain noise control structure, comprise metal Roof 1 and the sound-absorbing material layer 3 that is arranged on metal Roof 1 medial surface, also be provided with damping shock absorption layer 2 between metal Roof 1 and the sound-absorbing material layer, damping shock absorption layer 2 upper surface and metal Roof 1 medial surface fasten with glue and are formed with adhesive phase 4, sound-absorbing material layer 3 by spraying and adhesive bonding at damping shock absorption layer 2 soffit, between be formed with adhesive phase 5.
Wherein, metal Roof 1 is the metal Roof structure.Sound-absorbing material layer 3 is inorfil sprayed coating or flame proofing organic fibre sprayed coating.Damping shock absorption layer 2 is the beam that rubber or Plastic expanded material are made, and it can be homogenous material, also can be the composite material that multiple material is made.
In the present embodiment, the thickness of damping shock absorption layer 2 is 5mm, and the thickness of sound-absorbing material layer 3 is 25mm.Rain noise control structure in the present embodiment, through acoustical testing, impact sound improvement amount can reach 50 decibels, and defening effect is better than existing every patter of rain structure greatly, and thickness is little, than common every patter of rain structure increase 5mm only, therefore, the rain noise of present embodiment control structural texture is simple, and defening effect is good, and construction easily, and cost is low.
The above person, it only is this novel preferred embodiment, when the scope that can not limit with this this novel enforcement, the simple equivalence of namely generally doing according to this novel claim and novel description changes and modifies, and all still belongs in the scope that this new patent contains.
