Description
(1) technical field
The utility model is a kind of test laboratory of building field building materials parts, but is specifically related to a kind of to buildings ventilating performance of ventilating window laboratory.
(2) background technology
The room noise environment is the key factor that influences health and work efficiency, noise more than the 40dB is with appreciable impact crowd's sleep quality, the above neighbourhood noise of 45-50dB then can make the work crowd symptoms such as elevation of blood pressure, anxiety, agitation occur, and causes work efficiency to descend.Along with the development of urban transportation and construction in recent years, noises such as outdoor traffic, construction bring very big challenge for the control of architecture indoor noise circumstance; It is on the one hand traditional that to pass through the way that outer facade is windowed or perforate is ventilated improves indoor air quality and hot comfort be cost to sacrifice acoustic environment all, on the other hand at the excessive special occasions of some ambient noise, especially on the overpass next door, have to sacrifice IAQ (indoor air quality) for the quality that guarantees indoor acoustic environment, the few ventilation even do not ventilated.Therefore how between ventilation and noise, to average out and become the main difficult point problem in this field.
Emerge various forms of ventilated and soundproof windows (ventilation soundproof window/ventilating noise reduction window) in recent years on the market, the technical characterictic of such forms is to be provided with special air channel or pore at one or several position to carry out air exchange to allow indoor and outdoor on the architecture basics of conventional forms, but simultaneously for to guarantee not make as far as possible outdoor various noises with in the air inlet chamber, professional noise elimination design has been carried out in this air channel, greatly change noise, the ventilation level of indoor and outdoor, improved the inhabitation environment for use and the condition of human body.
Yet since at present at home with the international testing field, determine to have formed relative perfect test evaluation system by long-term research for the oise insulation factor (comprising laboratory and on-the-spot test) of elevation of building member; And ventilation lacks laboratory testing method and corresponding device thereof under the standardization operating mode all the time as another main performance index of ventilated and soundproof window.Therefore how to test and differentiate the problem that the ventilating sound-proof component performance is called the important of present the sector development and presses for solution.
(3) utility model content
The purpose of this utility model is to fill out under mouthful sealing good premise condition in order to build at the assurance forms, (0 ~ 50pa) tests the ventilation of forms itself, thereby judges the test laboratory whether its performance of ventilating adheres to specification with outdoor recurrent pressure state under the simulation actual state.
The purpose of this utility model is realized by following structure.
