Abstract
The utility model relates to a natural draft sound arrester, its characterized in that: the device installs on factory building frame roof beam all around as the wall body, and it falls the protective screen of making an uproar including the compound sound absorption and insulation barrier of a plurality of lights and a plurality of ventilation that set up side by side, the compound sound absorption and insulation barrier's of each light both sides fall the protective screen fastening connection of making an uproar with compound sound absorption and insulation barrier of another light or ventilation respectively. The utility model discloses owing to fall the protective screen of making an uproar uses that combine together with the compound sound absorption and insulation barrier of light and ventilation, consequently can make the heat dissipation of inside strong noise equipment natural draft when guaranteeing the noise reduction effect, solved natural draft and the noise reduction effect can't be double the problem. The utility model discloses because the direct mount does not need solitary construction basis on factory building frame roof beam all around and rather than constituting an enclosure space, consequently reduced area, has strengthened the control effect of integrated noise, optimized the building wholly arrange with the view effect.
Description
Technical field
The utility model relates to a kind of sound arrester, particularly about a kind of natural ventilation sound arrester.
Background technology
According to the technological requirement in plant gas and GIS network control building, transformer and GIS network control equipment are usually placed in same building and this building needs nearer apart from factory circle.But because apparatus body noise is comparatively large, and by factory outside noise discharge restriction requirement, therefore need to carry out sound insulation and noise reducing at the outer acoustic barrier building isolated footing of building, which not only adds construction cost and too increase installation difficulty.Simultaneously, because transformer can produce certain heat in the course of the work, and these caloric requirements are discharged by ventilation and heat mode, therefore in order to meet ventilation and heat requirement, existing acoustic barrier needs to maintain a certain distance with building, but so not only expand noise-reducing device floor area and also distance barrier distance excessive time acoustic barrier noise reduction can greatly reduce, make natural ventilation heat radiation and noise reduction sound insulation can not reach requirement simultaneously.In addition, existing acoustic barrier Noise measarement effect in barrier acoustic shadow is relatively better, and sound can be gone out by diffraction outside barrier acoustic shadow, have a strong impact on Noise measarement effect and the overall landscape effect of factory building, therefore go industrial requirement principle to disagree with current industrial construction.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide that a kind of floor area is little, totally enclosed type and simultaneously realizing is dispelled the heat and the natural ventilation sound arrester of sound insulation.
For achieving the above object, the utility model takes following technical scheme: it comprises the multiple lightweight compound sound absorbing-insulating barrier and multiple ventilation noise-reduction barrier that are arranged side by side; The both sides of lightweight compound sound absorbing-insulating barrier described in each are fastenedly connected with lightweight compound sound absorbing-insulating barrier described in another or described ventilation noise-reduction barrier respectively.
Described lightweight compound sound absorbing-insulating barrier comprises the sound insulationg board and a muffling unit that are fastenedly connected.
Described ventilation noise-reduction barrier comprises the duct-ventilated hollow metal profile plate of a tool, is filled with the centrifugally glass-wool for sound-absorbing at described shape intralamellar part.
Described sound insulationg board adopts fibre-reinforced cement slab material to make; Described muffling unit comprises a perforated sound-absorbing plate, is provided with the centrifugally glass-wool for sound-absorbing and the plain weave alkali-free hydrophobic glass silk cloth fixing described centrifugally glass-wool between described perforated sound-absorbing plate and described sound insulationg board.
Described lightweight compound sound absorbing-insulating barrier and described ventilation noise-reduction barrier are installed on the Vierendeel girder of factory building surrounding as body of wall.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is due to the use that lightweight compound sound absorbing-insulating barrier and ventilation noise-reduction barrier combined, therefore can while guarantee noise reduction, inner strong noise equipment natural ventilation be dispelled the heat, solve the problem that natural ventilation and noise reduction cannot get both.2, the utility model due to be directly installed on factory building surrounding Vierendeel girder on and with its formation one enclosure space, do not need independent foundation construction, because this reducing floor area, enhancing the control effects of integrated noise, optimizing building integral and arranging and landscape effect.
