Abstract
The utility model relates to a sound insulating ventilation window which belong to the technical field of noise control. The utility model is suitable for the design of the windows of house buildings. The utility model is composed of double layers of glass windows, wherein, each layer of glass window is provided with two movable window sashes (1), (3) and one to three fixed sashes. Sound absorbing materials or a sound absorbing structure (5) is arranged on the circumference of a part between the window frames of the double layers of windows. When the utility model is in the state of ventilation, the utility model can achieve the sound insulating effect of an ordinary single-layer window when the ordinary single-layer window is closed. The utility model has the advantages of favorable ventilating and sound insulating performance, simple structure, good lighting and low cost. The utility model is suitable for buildings adjacent to highways.
Description
The utility model belongs to the noise control technique field, is applicable to the window design of building construction, is specially adapted near the building of arterial traffic.
The window design of the most of building of China mainly is the angle from insulation, ventilation, daylighting, cold district such as northwest, northeast adopts double window, the general single window that adopts in other areas, some hot areas, south spacious corridor formula structures that adopt in order to ventilation more.Said structure is enough for insulation, ventilation, daylighting, but defening effect is not obvious, and it is more outstanding when ventilating particularly to open the window, and noise pollution is very serious.In recent years, the appearance of micro silencer ventilation shutter for the sound insulation ventilating problem that solves window certain effect is arranged, but sound insulation factor has only 10-13dB (A), and daylighting is relatively poor, can not satisfy actual needs.In addition, the structure that patent 89220934.8 " sound insulation vent window " is adopted is that sealed window adds mechanical ventilator, and its defening effect is good, and sound insulation factor can reach 25-27dB (A), but structure is complicated, needs to be equipped with mechanical ventilator.
Light materials such as more external developed countries' employing aluminium alloyss are made sealed window, and the indoor device that installs an air-conditioner solves the outdoor noise pollution problem.Another kind method is that European patent (patent No. EF87486) proposes to take sealed window to solve the sound insulation problem, and ventilation stack is set in window frame, and the window upper and lower sides is provided with the turnover ventilation opening respectively and solves ventilating problem, this method complex structure, cost height.
The purpose of this utility model provides a kind of sound insulation vent window, and it has, and simple in structure, sound insulation factor is big, ventilation and characteristics such as daylighting is effective, cost is low.
The structure of sound insulation vent window is seen Fig. 1 and Fig. 2, this vent window is made up of double-deck movable sashes and fixed sash and sound absorption construction, window frame is generally made by ordinary steel or aluminium alloys, thickness of glass on the sash is generally the 3-5 millimeter, movable sashes (1), (3) are 2 every layer, making can plug-type or flat opening, fixed sash (2), (4) are every layer of 1-3, wherein sash (4) is absolutely necessary, sash (2) can be provided with as required, its position should be placed on the top or the bottom of forms, and perhaps the position is respectively put one up and down.Distance between the two-layer window should be greater than 50 millimeters, be equipped with sound absorption construction (5) on the position around between the two-layer window frame, and the sound absorption material of filling can be porous absorption material and sound absorption construction super glass wool, polyamine fat vacuole foam, microperforated panel etc.
The operating principle of sound insulation vent window is seen Fig. 3.When using the sound insulation vent window, only open a movable sashes for every layer, and the sash of opening must interlock, between two-layer window, form gas channel, when air communication is crossed this passage,, thereby reduce noise owing to sound wave comes back reflective and changes the direction of propagation and loss acoustic energy between two-layer window.The sound wave that incides sound absorption construction (5) surface is in addition absorbed a part by sound absorption material, thereby also reduces a part of noise.When ventilation state, the defening effect when its defening effect can reach the single window window closing state.
Description of drawings.Fig. 1 is sound insulation vent window structural representation, and Fig. 2 is the A-A cross-sectional view, and Fig. 3 is sound insulation vent window ventilation state schematic diagram.Among the figure: 1,3-movable sashes, 2,4-fixed sash, 5-sound absorption construction.
Embodiment.The sound insulation vent window is the aluminum window of 1500 * 2000mm, the window frame width is 90mm, thickness of glass is 5mm, distance is 50mm between the two-layer window, movable sashes (1), (3) are plug-type, 2 every layer of fixed sash, i.e. (2) among the figure and (4), the sound absorption material in the sound absorption construction (5) is a super glass wool.Through laboratory tests, the double-layer ventilation sound proof window is in the time can opening sash (1) and (3) diagonal angle full open, and sound reduction index can reach 22-23dB, and sound insulation factor is suitable when closing with common steel sash; The double-layer ventilation sound proof window is when contract fully, and sound reduction index can reach 37dB.Sound reduction index was 34dB when common double window was closed.In addition, this sound insulation vent window is than the high 5%-10% of common double window cost (about 15-30 unit), and the low 30-50% of sound insulation vent window cost that is provided than micro silencer ventilation shutter or patent 89220934.8.
In sum, the sound insulation vent window that the utility model provides, it is simple in structure, cost is low, defening effect is obvious, has good performance of ventilating and lighting performance, reaches its intended purposes.
Claims (3)
1. a sound insulation vent window comprises movable sashes, fixed sash, it is characterized in that being made of double window, and the distance between the two-layer window is not less than 50 millimeters, and sound absorption material or sound absorption construction (5) are equipped with in the position all around between the double window window frame.
2. according to the described sound insulation vent window of claim 1, it is characterized in that movable sashes (1), (3) are 2 every layer, making can plug-type or flat opening; Fixed sash is every layer of 1-3, and wherein sash (4) is essential.
