Description
Technical field
The present invention relates to building construction technology field, specifically a kind of external wall of auto purification light pollution preventive.
Background technology
Curtain wall is a kind of construction wall trailing of novelty attractive in appearance, is the notable feature in modern high-rise building epoch.It imports China on the eighties in last century greatly, and the big and medium-sized cities large area such as Shenzhen and Guangzhou, Beijing, Shanghai adopt the building of curtain wall to be seen everywhere, but the light pollution caused thus is but that people are quite unexpected.The light pollution (or being called din-light) of curtain wall, the curtain wall referring to highrise building have employed coated glass or coated glass, the reflected glare produced due to the mirror-reflection (normal reflection) of glass when direct sunlight and skylight are irradiated on glass surface.
Light pollution is the assailant manufacturing unexpected traffic accident, stand one flickering curtain wall mansion, just as the huge mirror of a bulk of tens meters wide, nearly hundred meters high, and traffic conditions and traffic lights are reflected (or even multiple reflections), reverberation enters in the automobile of running at high speed, and can cause sudden Whiteout and the eyesight illusion of people, can cover the visual field of driver instantaneously, or make him feel Light-headedness, seriously endanger the visual performance of pedestrian and driver.Those build the curtain wall near residential quarter in, can be formed reflective to the building of surrounding.According to optics expert research, the reverberation of minute surface glass of building is stronger than solar radiation, and its reflectivity is up to 82% ~ 90%, and light is almost reflected entirely, greatly exceed the scope that human body can bear.Sunlight reflexes in room by summer, and the indoor original good atmosphere of the most destructible of strong dazzling light, also makes room temperature on average raise 4 DEG C ~ 6 DEG C.The long-time people working and live under the bright contaminated environment of white, easily cause visual impairment, produce Light-headedness, insomnia, palpitaition, appetite declines and the similar neurasthenic symptom such as depressed, the normal physiological of people and psychology are changed, goes down for a long time and can bring out physiology and mental disease.In addition, the natural beauty not anti-pollution of curtain wall clear transparent, especially more in air dustiness, air pollution is serious, the northern area of drought, curtain wall very easily covers dirt and receives dirt, this is for civic landscape, not only can not increase " light ", loses on the contrary " face ".Material used is inferior, and construction quality is not high, and occur that color and luster is uneven, ripple is different, due to the uncontrollability of light reflection, result in the mixed and disorderly of luminous environment.
Light pollution produces under following specified conditions:
(1) large area high reflectance coated glass is employed; (2) produce under specific direction and special time; (3) degree of light pollution and direction, the position of curtain wall and highly have substantial connection.Because the visual angle of people has the greatest impact within 2 meters of high left and right ± 15 degree angles, the intensity reverberation of light reflection is to square being inversely proportional to of distance of human eye.In recent years, national governments and relevant learned society attach great importance to light pollution problem, successively disclose a series of technological document, standard and decree, control light pollution.
The problem of China to curtain buildings also gives great attention, within 1996, plays curtain wall engineering technical specification, strengthens the regulations such as the temporary provisions of building curtain wall engineering management and in succession put into effect, make control curtain wall engineering quality have Regulations.Various places, according to the actual conditions of oneself, also take some corresponding feasible measures.The appearance of light pollution problem is not that curtain wall has not done, but how to do.The material of curtain wall is developed into steel plate, aluminium sheet, alloy sheets, marble slab, enamel firing knot tying etc. from single glass by current high-tech development, pass through appropriate design, by curtain wall together with the combined curtain wall of the materials such as steel, aluminium, alloy, high-rise building not only can be made more attractive in appearance, can more effectively reduce curtain wall reflective and the light pollution caused, the deadweight of high-rise building can also be alleviated further, give full play to the advantage of curtain wall building materials.The influence degree of curtain wall reverberation, depends on the intensity of orienting reflex light, all-transparent or translucent glass can be adopted to carry out the intensity of diminished reflex light, but most light directly injects indoor, interior temperature certainly will be caused to raise.At present, the structural form that can adopt has two kinds:
(1) double-layer glass vented construction.This being configured in has different effects different seasons.In summer, put down translucent roller shutter, open exhaust duct and ventilation opening, after being reflected by roller shutter, can most of radiant heat be removed.In winter, enclosed ventilation mouth, turns off exhaust blower, and double-layer glass can play again the effect of insulation, prevents indoor heat loss, and the shortcoming done like this is that investment cost is larger.
(2) infra-red heat structure.By the saturating infrared characteristic of deielectric-coating coating, utilize heat-absorbing water pipe can using the part of the most of heat absorption in sunlight as building thermal water source's thermal source, no matter can effectively use in summer and winter.Weak point is curtain wall thickness requirement comparatively large, but can be adjusted by the measure such as hanging up outside curtain wall.Glass plays critical effect to curtain wall, the type of glass of curtain wall cautiously will be selected according to some parameters of glass, select the glass having and reduce glare properties, these parameters comprise the light climate parameter of construction site, to transmission number, the reflectance factor of visible ray, to the sound transmission coefficient of daylight, reflectance factor and absorption coefficient, also have thermal transmittance, coefficient of thermal expansion, and thickness, maximum size, weight, wind resistance power etc.But well-known, glass has transmission, absorption and reflection characteristic for light.Curtain wall just have employed dissimilar glass according to these characteristics.Glass for curtain wall generally has clear glass, coloured glass, heat absorbing glass, coated glass, coated glass, laminated glass and photochemistry glass etc.Their respective pluses and minuses can be recognized in the glass just these curtain walls used.
In addition, in the irradiation of sunshine and artificial light sources, there is a series of conversion in the toxic and harmful in building surrounding enviroment.If transform the toxicity that can reduce poisonous and harmful substance or make poisonous and harmful substance to be degraded thoroughly mineralising, yes, and we wish to see very much.But major part transforms all can generate more complicated or that toxicity is stronger material, the mankind in serious harm architectural environment and biology health.Make this conversion can be conducive to the purification of hazardous substances in architectural environment, built environment just may be made to design while energy-conservation, green and environmental protection.And general curtain wall often produce light reflection cause physical pollution, and do not possess the function of auto purification Outer Environment, therefore finding a kind of can the prevention and control light pollution poisonous and harmful substance had again in auto purification Outer Environment be the requirement of Outer Environment, particularly Curtain Wall Design.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of external wall of auto purification light pollution preventive, the effect of the poisonous and harmful substance in auto purification Outer Environment can be had again by prevention and control light pollution.
The present invention is achieved through the following technical solutions: a kind of external wall of auto purification light pollution preventive, comprises the pedestal be fixed on exterior wall; Described pedestal is fixed with equally distributed glass marble; On described glass marble, load has can be the photoinduction catalyzer of free radical and electron-hole pair by water decomposition.
It is further: described glass marble replaces with and is evenly distributed on circular groove on pedestal or projection; On the surface of described circular groove or projection, load has can be the photoinduction catalyzer of free radical and electron-hole pair by water decomposition.
The material of described pedestal is glass, concrete or macromolecular material.
Described catalyzer sticks to glass marble surface at glass marble formative stage, or with the form of pad pasting fix after shaping glass marble surface.
Described glass marble leaves gap each other, and glass marble exposes base part and is less than hemisphere.
Described glass marble each other near, glass marble exposes base part and is greater than hemisphere.
In glass manufacturing process or in curtain wall installation process, polishing makes its surface form comparatively regular diffuse reflection as far as possible, thus when avoiding solar irradiation to be mapped on curtain wall, produces reflection and cause light pollution.Simultaneously because circular glass ball is that load has photoinduction catalyzer, when solar irradiation is mapped to curtain wall surface, produce decomposition water and form free radical (OH) and electron-hole pair, the existence of these oxidisability particulates can make to be adsorbed on curtain wall surface or be free on the neighbouring degradeds such as the haze of hazardous compound and innoxious of carrying.3rd, such structure adds curtain wall surface area more than enough absorption can more carry the haze of hazardous compound and other hydrones such as PM2.5 and PM10.4th, along with the change of weather, curtain wall surface forms moisture film can reduce light reflection, also can dissolve hazardous compound, thus reduces gas and the solid pollution of Outer Environment, also can reach the effect of auto purification metope through rain drop erosion.Here purification comprises process and is attached to beyond the dirt on surface, also comprises the organic effective degraded in Outer Environment.
