Through the ages, safety is related to life and death, need to take precautions, put an end before an accident.In modern curtain wall building, the safety of the building first depends on a good design, and a good design can eliminate the safety risks in the early stage of the building.In recent years, some good structural design measures have appeared in the design of the building curtain wall, which are gradually improving the possible safety risks of the curtain wall, and promoting the renewal of the relevant specifications of the curtain wall. In recent years, the news about the damage caused to pedestrians and vehicles below after the glass explosion has frequently appeared, and there are even more cases of the overall opening fan falling off, causing human death.These are all typical safety hazards caused by the curtain wall. Most of the curtain wall is used in super high-rise buildings. The objects falling off of super high-rise buildings cause more and more damage with increasing height, and even achieve the damage of bullets to the human body.Falling pendant on the site can easily wear a helmet.
Generally, each floor of the high-rise building is a fire partition, and the spider system curtain wall, as the peripheral protector of the building, plays the role of preventing fire and smoke from entering the adjacent floors.This raises very high requirements for the inter-layer sealing between the curtain wall and the structure.There have been a number of high-rise building fires. The canopy serves as a blocking component above the main entrance, which is at the core of personnel in and out, and its possible damage is huge. And canopy as a cantilever component, belongs to the form of structure.The combination of the two has put forward high requirements for the safety of the canopy.
The factors affecting the safety of the building curtain wall mainly include the following aspects:
defect in material
The modern curtain wall design is not reasonable
Construction is not done according to Figuration
New concept of safety design of curtain wall- -safety element analysis method
Curtain wall safety design analyzes the elements of damage production
The damage of curtain wall requires the following conditions:
The curtain wall itself is destroyed
The curtain wall falls off
The components contact with people
To avoid the damage to the curtain wall, only need to design the above three conditions, eliminating any of the conditions can guarantee the safety of people.For example, there are a variety of solutions to the problem of preventing tempered glass self-explosion. In order to prevent the destruction of the curtain glass window itself, semi-tempered sandwich glass can be used as semi-toughened, and semi-tempered sandwich glass will not be self-explosion damaged.
