Abstract
The utility model relates to a sound insulation and ventilation window, which belongs to the control technical field of environmental noise. The utility model is characterized in that the sound insulation and ventilation window which corresponds to a wall body with a box type structure is made on a wall surface on one side of the existing window. The sound insulation and ventilation window is composed of a gypsum board (2), a steel board (3), sound insulation material (4), a scavenger fan (5), a window screen (6), a shutter (7) and an airflow passage (8). The sound insulation and ventilation window replaces a part wall body and is installed all together with a window. Under a condition that the window is not opened, indoor ventilation and lighting can be maintained. The utility model has the advantages of good sound insulation and temperature preservation effects and low cost. The sound insulation and ventilation window can be used for frontage buildings.
Description
The utility model belongs to urban environment noise control technology field, particularly belongs to overlooking traffic noise control technology field.
The quality of sound isolation of windows performance is directly connected to the operate as normal, life and the rest that are in other, commercial bustling district of the main line of communication and the group mixed zone building user of factory.Be positioned at the highest environment noise region building at the front for those, large tracts of land daylighting is the weak link of headache often, and particularly indoor when needing ventilation, outdoor noise is even more serious to indoor influence.
At present abroad solve overlooking noise indoor influence is mainly contained two kinds of methods: a kind of is to adopt light material such as aluminium alloys to make sealed window, the indoor device that installs an air-conditioner solves ventilating problem, ventilation stack is set in window frame, the upper and lower side of window is respectively equipped with to import and export ventilates, solve ventilating problem, this apparatus structure complexity, the cost height; In addition, be exactly in the suburb or rural construction dwelling house, villa district, to avoid the harm of city traffic noise pollution.Domestic transport solution noise does not also have maturation method to indoor influence, the structure that patented product " sound insulation vent window " (patent No. is 89220934.8) is adopted is to fan installation sealed window on glass in one of general window to add mechanical ventilator, though its defening effect is good, sound insulation factor reaches 25-27dB (A), but its complex structure, inconvenient maintenance, and influence indoor lighting; The structure of patented product " multifunctional adjustable noise control window " (patent No. is 97215504) is more complicated, and long-term use maintenance is a difficult problem.
The purpose of this utility model provides a kind of sound insulation vent window, adopt simple structure, under the situation that does not influence original window daylighting, both can utilize self pressure differential and temperature difference to cause that air flows, can adopt the circulation of mechanical ventilation again, reach the purpose of ventilation noise reduction for indoor maintenance fresh air; And have the low characteristics of sound insulation, high insulating effect and cost.
The sound insulation vent window that the utility model provides is to make the sound insulation vent window (1) (as shown in drawings) that is equivalent to the box structure body of wall on a side wall of original window, and this vent window is made up of gypsum plank (2), steel plate (3), sound absorption material (4), ventilation fan (5), screen window (6), shutter (7), gas channel (8).The part that is used to eliminate the noise can be a porous absorption material, also can be sound absorption construction, and this sound absorption material should have efficient full range band sound absorption and fire resistance.This sound insulation vent window instead of part body of wall is installed with window, under the situation of not opeing the window, keeps room ventilation and daylighting.
Sound insulation vent window operating principle as shown in the figure: when needs are taken a breath, open ventilation fan (5) and shutter (7), air-flow is by in noise elimination passage (8) inlet chamber, sound wave along channels spread causes air and fiber vibration in the porous absorption material (4), make a part of acoustic energy be converted into heat energy and lose, outdoor noise decay gradually like this with regard to constantly being absorbed by sound absorption material.If do not drive ventilation fan, only open shutter, can utilize the temperature difference of indoor and outdoor and pressure differential to cause that air flows, and also can reach the purpose of ventilation noise reduction.
Description of drawings: Fig. 1 is the outdoor elevation of window; Fig. 2 is the indoor elevation of window.Among the figure: the sound insulation vent window of 1-box structure wall form; The 5-ventilation fan; The 6-screen window; The 7-shutter.Fig. 3 is sound insulation vent window (1) A-A section sectional view.Among the figure: the 2-gypsum plank; The 3-steel plate; The 4-sound absorption material; The 8-gas channel.
Embodiment.Make the high 1620mm that is in a side of original window, wide is 390mm, thick is the box structure body of wall of 360mm, be positioned at the box structure upside at outdoor body of wall ventilation fan (5) is housed, the downside that is positioned at box structure at indoor wall is equipped with shutter (7) and screen window (6), box structure is made of gypsum plank, steel plate and sound absorption material from the outer to the inner successively, and gypsum plank thickness is that 5mm, steel plate are that the thick A3 sheet material of 1mm, sound absorption material are porous absorption material, and thickness is 10mm.After using this sound insulation vent window, after the user closes original window, still can ventilation, make room air keep fresh, clean, and the street traffic noise will never import into indoor because of ventilation.After tested, sound insulation factor was 28-30dB (A) when this sound insulation vent window ventilated, and was much higher than the sound insulation factor of the 10-15dB (A) of layer glass window, and suitable with the sound isolation of windows amount of double-layer glass.Compare cost low about 20% with similar sound proof window.
In sum, the sound insulation vent window that the utility model provides is simple in structure, cost is low, tolerant noise-insulating warm-keeping is effective, under the situation that does not influence former indoor lighting, has reached the dual purpose of ventilation noise reduction.
Claims (2)
- One kind sound insulation vent window, body of wall by box structure constitutes, it is characterized in that the box structure body of wall is positioned at a side of original window, this body of wall is made of gypsum plank (2), steel plate (3), sound absorption material (4) from the outer to the inner successively, gas channel (8) is left at this structure middle part, the outdoor body of wall upside that is positioned at box structure is equipped with ventilation fan (5), and the indoor wall downside that is positioned at box structure is equipped with shutter (7) and screen window (6).
- 2. according to the described sound insulation vent window of claim 1, it is characterized in that the inboard of box structure body of wall (1) is equipped with sound absorption material or sound absorption construction all around.
