Bay window, glass curtain wall, dry hanging stone, elevator ... all kinds of novel concepts, has made a beautiful house. However, in the recent period of time, the falling window, the self-destruction of glass curtain walls, and the accidents in which elevators were trapped and hurt people have occurred one after another. This has led to a deep reflection on contemporary residences. We live well, but we must first live safely.
Since the advent of glass curtain wall building, it has been favored by many builders due to its light weight, short construction period and stylish appearance. Since the glass curtain wall was first used in the Beijing Great Wall Hotel project in 1983, China has rapidly developed into the world’s largest glass curtain wall producing country and a big country in more than 20 years.
With the increase of the service life, the hidden dangers of the glass curtain wall are gradually exposed. This kind of material consumes energy and light pollution, causing inconvenience to pedestrians and surrounding buildings on the road. The explosion and shedding of the glass curtain wall have become a potential safety hazard for the city. At present, the country’s allowed tempered glass self-explode rate is 3%. “Although the current quality and strength of architectural glass are adequately protected, after all, the earthquake resistance and deformation resistance of glass are insufficient. Once typhoons, hurricanes, earthquakes, hailstorms and sudden temperature changes are encountered, they may cause safety. event."
The "Technical Specifications for Glass Curtain Wall Engineering" issued by the Ministry of Construction in 1996 clearly stipulated that: after a normal use of a glass curtain wall building, a thorough inspection shall be conducted every 5 years; glass, seals, sealants, and structural silicone sealants shall be inspected. .
The glass curtain wall will cause light pollution (or noise) of the light-contaminated glass curtain wall. It means that the curtain wall of the high-rise building is coated with coated glass or coated glass, and the mirror reflection of the glass is when the direct sunlight and sky light shine on the glass surface. (ie, a regular reflection).
Light pollution is the murderer of accidental traffic accidents. When reflected light enters a high-speed car, it can cause sudden and temporary blindness and vision illusions. It will temporarily obscure the driver’s vision or make him feel dizzy. Harming the visual function of pedestrians and drivers. .
Light pollution has also caused trouble for the lives of nearby residents, especially the glass curtain walls built near the residential quarters, reflecting the surrounding buildings. According to optical experts, the reflected light of the mirror building glass is stronger than sunlight, and its reflectance is as high as 82% to 90%. The summer sun is reflected in the room and the room temperature is increased by an average of 4 to 6°C. The air-conditioning expenditure increases substantially, affecting people's normal residential use. What is more, people who work and live in a white, light-stained environment for a long time are prone to vision loss, dizziness, insomnia, palpitations, loss of appetite, and depressed moods and similar symptoms of neurasthenia, resulting in normal physiology and Changes in psychology, long-term will induce certain diseases.
In addition, glass curtain walls are easily contaminated, especially in the northern regions where the atmospheric dust content is high, air pollution is severe, and drought is weak. Glass curtain walls are more susceptible to dust and dirt. This is not only an increase in the “city of light†but also a loss for the urban landscape. "face". Because of the inferior material used in some glass curtain walls, the construction quality is not high, and the color is uneven and the ripples are different, resulting in the glass curtain wall being like a magic mirror. In the sun, each glass does not appear to have a uniform light, but it diffuses everywhere. Obviously, such a building is difficult to reminisce in its lucidity and luxury. It can only make people feel bizarre and ridiculous, and the city’s image is greatly reduced.
