Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
A noise reduction structure for the roof of an industrial factory building is disclosed, which is shown in the figures 1 to 2 and comprises a clerestory 5 and a noise reduction plate structure.
Clerestory 5 sets up on 4 tops of factory building roof to be linked together with the factory building is inside, form convex structure between factory building roof 4 and the clerestory 5, the both sides of clerestory 5 are clerestory ventilation hole.
Fall the structure of making an uproar vertical setting respectively on the factory building roof 4 that is located clerestory 5 both sides, and have a determining deviation between the clerestory ventilation hole that is located the homonymy, specifically the horizontal distance more than or equal to clerestory 5's height between sound insulation baffle 1 and the clerestory 5 to avoid sound insulation baffle 1 to produce great influence to factory building ventilation cooling, combine the heat dissipation condition of factory building reality and set for the horizontal distance between sound insulation baffle 1 and the clerestory 5.
The noise reduction plate structure comprises a connecting frame 6, a sound insulation baffle plate 1, a perforated plate 3 and a sound absorption material layer 2.
The sound insulation baffle plate 1 is arranged on the outer side and fixedly connected with the top wall of the clerestory through the connecting frame 6, and the sound insulation baffle plate 1 is supported by the connecting frame 6 so as to ensure normal use under various loads. The connecting frame 6 is a steel structure connecting frame, has strong atmospheric corrosion resistance and can be used outside a factory building for a long time. The sound insulation quantity of the sound insulation baffle 1 is not less than 20dB (A). The height of the sound insulation baffle 1 is determined by the noise reduction requirement of the noise reduction structure, and the higher the noise reduction requirement is, the higher the height of the sound insulation baffle 1 is.
The sound absorption material layer 2 is clamped between the sound insulation baffle 1 and the perforated plate 3 and is fixedly arranged on the perforated plate 3 and used for greatly absorbing noise in a factory. A large number of mutually communicated micropores and gaps are formed in the sound absorption material layer 2, and the micropores and the gaps have good noise reduction effect. The thickness of the sound absorption material layer 2 is more than or equal to 50mm, the specific thickness is determined according to the frequency of the noise to be absorbed, the sound absorption material layer 2 needs to be thickened if the frequency of the noise is low, the frequency of the noise is high, and the thickness of the sound absorption material layer 2 can be properly reduced.
Form the ventilation air current passageway between the structure of making an uproar and the clerestory 5 falls, form horizontal ventilation air current passageway between the open end of clerestory 5 and the structure of making an uproar falls, form the vertical ascending vertical ventilation air current passageway along the structure of making an uproar falls between the roof of clerestory and the structure of making an uproar falls.
The utility model discloses when actually falling an uproar, the air current in the factory building gets into clerestory 5 perpendicularly, flow into clerestory 5's open end and fall the horizontal ventilation air current channel between the board structure of making an uproar by clerestory 5's open end, it falls the high efficiency noise reduction to fall the sound absorbing material layer 2 in the board structure of making an uproar to the noise, again by sound insulation baffle 1 further fall the noise, the air current after falling the noise and flow into external environment perpendicularly, the setting of falling the board structure of making an uproar not only can fall the effect of making an uproar well to the noise, also can guarantee the ventilation condition in the.
