Description

Sound isolating window with function of airing

The utility model is a kind of building fittings that is made of the universal machine technology.Under the prerequisite of not changing existing construction module and standard, design shape is widely used on all kinds of (old, newly-built) building arbitrarily.Be to improve people's life and working environment, improve a kind of necessaries of indoor comfort.

In the metropolis, driving vehicle and other noise have become existing big public hazards on the traffic route.Live in the resident and the staff in unit orderly room along the street of both sides, street, by having no peace day or night that these public hazards are disturbed.Simultaneously, modern medicine proves; People's numerous disease is all relevant with the influence of these public hazards.

Ordinary steel (wood) window of installing and using on the present civil building of China generally all only has daylighting, the two kinds of functions of ventilating.Noise is not had protective action basically.In order to exclude noise, also there is the noise insulation equipment of some double-deck seal glass windows and other form to come into operation.They have all played positive protective action to some extent.

With regard to the structure of existing all kinds of double-layer seal glass windows, they have his own strong points, and common feature is: (not parallel) glass that is parallel to each other is installed in window frame, and midfeather just forms an air layer.Slit or be designed to hermetically-sealed construction everywhere inside and outside the window frame, or do encapsulation process.To improve the tightness of window, reduce or eliminate the transaudient chance of air gap, because above-mentioned measure under the situation that sash is not opened, is to have improved from soundproof effect,, also guaranteed requirement from the requirement of daylighting.But all there is a very basic problem in they; Attend to one thing and lose sight of another.Make window lose the function of (when sash is not opened) natural ventilation.For the people that take a breath have to realize this requirement by other plant equipment and method.Because this shortcoming is added other reason, just make they application and popularize and to be subjected to certain limitation.

So, for common double window, how on structure design, the correct processing.Unification takes into account daylighting, ventilation, sound insulation, the functional requirement of this three aspect.Just can not take a breath after solving sound insulaton, ventilation does not just guarantee this a pair of contradiction of sound insulaton.

The purpose of this utility model is properly settled above-mentioned this a pair of contradiction exactly from structure design.Make the window unification have daylighting comprehensively, ventilate the function of sound insulation.

1, top and the bottom (left and right) symmetry is equipped with two ventilation bodies in window frame.Advancing on each ventilation body, air outlet all connects mutually.Because the density of outdoor air, temperature, humidity, degree of mobilization (wind-force and wind direction) is all changing with season and round the clock constantly.And the sealing of indoor because space, people's activities and various heat energy with go along with sb. to guard him the behavior in service of equipment, wait the effect and the influence of other reason, make the physical state of room air also change constantly, but on amount,, tangible difference is arranged all then as comparing with outdoor air.Based on so objective prerequisite, in this is novel, two ventilation bodies have been symmetrical arranged.Top is the air draft body, and the bottom is the air intake body.Indoor-outdoor air is connected mutually by air channel in the ventilation body, and under the effect of hot pressing and blast, it is outdoor that room air flows out, and flow of outside air is gone into indoor, and the air circulation convection current is got up in the whole room, reaches and improves IAQ (indoor air quality), satisfies people's requirement of taking a breath.

2, air channel structure reasonable in design promptly guarantees ventilation, and it is indoor to prevent that again outdoor sound wave from entering here.

3, the rational non-parallel glass planar mounting structure of design shape promptly satisfies the daylighting requirement, reaches the sound insulation index again.

4, hermetically-sealed construction is all adopted in the window slit, to guarantee the tightness of window, eliminates the transaudient chance in slit.

5, frame construction reasonable in design guarantees that window has enough rigidity.

This novel structure is as follows:

In a case type window frame, top and the bottom (left and right) symmetry is equipped with two and advances the exhaust ventilation body.Top is the air draft body, and the bottom is the air intake body.Two-layer sash is equipped with in the centre, and each sash can change merit freely and open.Forms outside sash is opened to outdoor, and the inboard sash of forms is opened to indoor, forms thickness 80-120mm, and the high wide size of window is any.

The ventilation body is a ventilation components that external form is a cuboid.As shown in Figure 2.It has lamina rara externa, median septum, and arbitrary shape lattice sheet, liner plate (sheet) blinds waits composition.Each symmetric arrangement has two air intakes, air outlet on the two sides, ventilation inside and outside.The air channel form is two " U " type air channel symmetric arrangement in the ventilation body." U " type duct cross-section is the rectangle cross section.In order to make noise waves reach certain attenuation in the air channel, simultaneously, guaranteeing again can have enough ventilation volumes under certain resistance condition.On " U " type air channel, some liners have been increased again.All liners on the air channel, plate all adopt quality loose, have definitely the sound-absorbing sound insulation materials of porosity make.Simultaneously, the strict again each other sealing of each dividing plate of air channel.

Calculate with experiment and show; The appropriate design in air channel is to guaranteeing natural ventilation rate, and the whole sound insulation value of window influences very big.Generally getting " U " type air channel length of run (L), to be slightly less than forms wide, and it is thick that air channel wide (B) gets 1/2 forms.High (H), when H ≈ 1.2B, liner spacing δ≤B/3, effect is better.

Advance, the inner air channel of row's ventilation body form is identical.But anti-blast cap is equipped with in air draft body exit.And enter place, air port in the endosome indoor, the movable louvre blade of adjustable openings size then is housed.

Various ways such as in addition, experiment shows, the air channel form is not limited to a kind of form in the ventilation body, and it also can have labyrinth type, and honeycomb is serially connected.

This new design the non-structure that is parallel to each other of layer glass, the glass of forms internal layer (side) is installed with the form on upright plane and the form of the upright setback face of glass of outer (side) is installed shown in figure three.The mutual structure of a plane like this and setback face, the best that can make window obtain daylighting and sound insulation is unified effect.Because light source and noise source are on the different azimuth in space.The sunlight line shines earthward from sky, if light is removed to meet with certain inclination angle in the plane, can obtain to improve the effect of daylighting area.The noise waves then motor vehicle by ground sends, upwards to around diffusion because glass planar on the high-rise building window and sound wave direction angle of slope in the same way, then can obtain the effect of deflection sound wave angle of incidence, and place, setback face β angle, also have and separate, weaken the effect of acoustic wave energy.Know by calculating with experiment: tg α=(a)/(b), (a d looks concrete structure and determines), during 9 °～11 ° β=90 of α ≈ °-α, effect is better.

The one's own profession type does not have specific (special) requirements to glass material, and sheet glass 3-5mm thickness commonly used all can.

This 3rd novel feature is, according to existing building standard and modulus, not only can be made into the window of arbitrary shape dimensions, to satisfy the supporting use of new building thing, and can design body arbitrarily, make the structure of cover, with present window integrator on the building, old building is transformed, to satisfy people's different needs.Its specific practice is as follows:

1, removes inner layer sash on these novel middle forms, just become by framework the body that ventilates up and down, the single window that outer (side) sash constitutes.

2, be inner layer sash with existing window on the building, and be benchmark, above-mentioned member is installed with its position.And seal with the body of wall window opening.

3, on glass the punching (or the glass that removes the angle that changes the outfit) of existing window and the corresponding position of the body inlet and outlet that ventilates up and down to guarantee to form the natural ventilation road.

4, with adhesive tape or weather strip, the slit everywhere on the existing window of sealing then forms one mutually,

Above-mentioned work is implemented shown in figure four, can be easy at the scene, promptly finish.

For adapt to and satisfy some buildings need join fixed sash large-scale window requirement this novelly can also be designed to structure shown in figure five.

This novel enforcement is shown in figure one.

By to the sound insulation air hole performance test after the overall package, the result is as follows:
