Description

Glass curtain wall capable of preventing light pollution

Technical Field

The utility model relates to a glass curtain wall technical field, concretely relates to prevent light pollution's glass curtain wall.

Background

The glass curtain wall is a new wall form of the present generation, it is a building external protective structure or decorative structure which is composed of supporting structure system and glass, and has a certain displacement ability relative to main structure, and does not bear the action of main structure, it is characterized by that the factors of building aesthetics, building function, building energy-saving and building structure are organically unified, and the building can present different tones from different angles, and can give dynamic beauty to people along with the change of sunlight, moonlight and lamplight. However, glass curtain walls also produce severe light pollution, which causes the following damage to human and bird lives:

(1) the reflected light of the glass curtain wall enters the automobile running at high speed, so that sudden temporary blindness and visual illusion of people can be caused, the sight of a driver can be stimulated instantly, or the driver feels light and dazzles, and serious harm is caused to pedestrians and the driver; (2) the glass curtain wall can form reflected light for surrounding buildings, and according to the research of optical experts, the reflectivity of the glass reflected light of the mirror building is up to 82% -90%. People who work and live in a white and bright polluted environment for a long time are easy to cause vision loss, and have symptoms similar to neurasthenia, such as dizziness, insomnia, palpitation, appetite reduction, low mood and the like, so that normal physiology and psychology of the people are changed, and certain diseases can be induced after the people for a long time; (3) the glass plate surface size of a newly built building is larger and larger in design, and various glass curtain walls are increased day by day, so that the building height is higher. The phenomenon of 'spontaneous explosion' caused by the breakage of various glasses under the irradiation of sunlight after the glasses are installed sometimes occurs; (4) the glass curtain wall of the building reflects the surrounding scenery, so that birds can not be aware of the danger before eyes and often hit the glass without slowing down the speed. According to the FLAP statistics of the organization of bird protection volunteers, only in Toronto, one million to nine million waiting birds die of the glass curtain wall every year.
