Description
Technical field
The utility model relates to a kind of door and window, particularly relate to a kind of not only can natural ventilation but also can the metal door and window of insulating noise and anti-haze.
Background technology
Along with China's rapid development of economy, the economic frequency of people greatly improves.Meanwhile, along with Chinese Urbanization, industrialized quick propelling, people more and more concentrate on business district and occupy, and the life impact of noise pollution on people is increasing.And the room air that the air pollution that interior decoration causes, atmosphere draught-free cause is muddy etc., and problem more and more endangers the healthy of people, bring have a strong impact on to daily life, working and learning.Now, existing door and window starts to show its limitation.When opening door and window ventilation, in discharge chamber muddy or pollute air time, traffic noise pollution can enter indoor, and affect the normal rest of people, mosquitos and flies also has the possibility flown within doors, if nobody home, dangerous, meet once in a while rain also can drift ice in indoor, particularly at night, noise can affect the normal rest of people, make people be difficult to fall asleep, even occur the symptoms such as anxiety; And close the doors and windows, obstructing traffic noise pollution can enter indoor, but also hamper the normal circulation of indoor-outdoor air, indoor originally muddy air is made to become more muddy, muddy or contaminated air prolonged stay is in room, people can be allowed to feel uncomfortable in chest, have difficulty in breathing, have a strong impact on the physical and mental health of people.Especially for the people of live and work at the building housing-group of urban viaduct both sides and speedway both sides, noise pollution is more serious, due to the defect in the design of traditional building doors and windows, noise is imported into by building doors and windows, and the people harassed cannot be worked and have a rest.In order to eliminate noisy sound, conventional solution has: (1) installs noise barrier at both sides of highway, and the noise sent by motor vehicle is reflected in highway region; Though its structure is simple, cost is still very high, and erasure effect is not obvious, and high noisy easily worsens the environment on road, causes accident.(2) at the forced ventilation sound arrester of building drive, noise damping material is absorbed, and pass into air to indoor simultaneously; Window is arranged to be made up of inside and outside layer glass by it, arranges noise elimination structure between layer glass, and above inner glass, arrange air inlet port and ventilation blower fan, sets out gas port in the below of outside glass.This soundproof window utilizes the noise elimination structure between inside and outside glass to abate the noise, utilize blower fan by the air channel forced ventilation between inside and outside glass, although to some extent solve external noise problem, but its cost is higher, complex structure, it utilizes blower fan forced ventilation, need the energy of at substantial on the one hand, form heat pollution, blower fan also can produce new noise simultaneously, and blower fan is not easy to safeguard; On the other hand, under powering-off state, blower fan quits work, and its effect of natural ventilation is poor.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides one both can natural ventilation, has again good insulating noise and anti-haze effect, and the door and window of the simple metal of structure anti-haze ventilation noise reduction.
For achieving the above object, technical solution of the present utility model is: the door and window of a kind of metal anti-haze ventilation noise reduction, and it comprises frame, fan frame and fan; Fan comprises the hole plate, sound insulation ventilating board, anti-haze layer and the warming plate that have Process; Hole plate is fixed on the fan frame inwall of outside, sound insulation ventilating board is fixed on the fan frame inwall inside hole plate, anti-haze layer is fixed on the fan frame inwall inside sound insulation ventilating board, warming plate divides warming plate to form by polylith, in the middle of the indoor of the upper and lower side frame of fan frame and the centre of left and right side frame indoor is fixed with bracing frame respectively, each point of warming plate can be connected to respectively pull fan frame indoor circumferential side frame and bracing frame in the buckling groove that arranges; The curve ruler comprising multiple V-shape is bent to by metallic panel absorber, sound insulation ventilating board is made up of the Multiple Stage Curve plate be fixed on fan frame inwall, each layer curve ruler is horizontally disposed with according to identical mode, between it, interval is identical, and between adjacent curve plate the minimum point of upper graph plate lower than the peak of curve ruler below; Anti-haze layer is made up of active carbon layer clamping between double layer of metal silk screen and silk screen; Frame has with each overlap joint position of fan frame the sealing joint strip being fixed on frame or fanning on frame.
The described above structure bending to the metallic panel absorber of the curve ruler of sound insulation ventilating board is: be shaped with multiple large sound absorption pit in the surface pressure of metal sheet roof covering, be connected by recessed channel between large sound absorption pit, also be provided with multiple little sound absorption pit in the gap of large sound absorption pit, metal sheet roof covering be also provided with and numerous pierce micropore.The large sound absorption pit of noise sound wave on metallic panel absorber, recessed channel, little sound absorption pit, pierce micropore reflection repeatedly, diffusion and a large amount of dispersions, consumed energy, sound attenuation clearly, through the test of national construction engineering quality inspection center, sound absorption coefficient is 0.8, and sound-deadening and noise-reducing effect is very good.
The hole diameter of hole plate described above is 1.5-2mm, pitch-row 2.5-3mm.This hole plate can be dust-proof, ventilates again.
Fan frame described above is respectively equipped with relative curved convex identical with curve ruler shape on the inwall of clamping sound insulation ventilating board both sides, each curved convex lays respectively between two adjacent curve plates, each curve ruler both sides are connected in the curved convex of two relative fan frames respectively, and outdoor end and indoor end are by hole plate and anti-haze layer jam-packed.The curve ruler both sides of sound insulation ventilating board are connected in the curved convex of fan frame, and outdoor end and indoor end are by hole plate and anti-haze layer jam-packed, and it connects and fixes firm, is easy to dismounting and change again, and repair and replacement are convenient.
Because sound is with linear transmission, so sound insulation ventilating board of the present utility model can insulating noise, and wind can change wind direction, so sound insulation ventilating board can ventilate, the hole plate of the utility model outside can dustproof ventilated; Anti-haze layer can remove haze by dust control by ventilation, and it is positioned at indoor, after the activity of active carbon layer lost efficacy, directly can change, can not hinder other component; So, as long as by warming plate pull out, the utility model both can insulating noise, again can natural ventilation, dust-proof except haze, and sealing joint strip by the utility model at the handing-over gap sealing of frame with fan frame, the dust such as wind, noise, haze can only be entered by hole plate, noise of the present utility model are isolated, dust-proof except haze better effects if.According to the difference of sound insulation ventilating board thickness, the coefficient of its insulating noise is at 10-40DB.The utility model structure is simple, and technique is simple, is easy to manufacture.When needing insulation, warming plate can be installed.
