Analytic: subway security system USES security glass and security space structure
The subway disaster happened precautionary difficulty is very big, after the disaster relief work also very not easy, as early as in countries on a large scale before the subway construction, the subway security problem will become the part of the government, architectural design units and the masses and the focus of attention, and the relevant personnel and the prevention of fire, explosion problem to carry on the thorough research and discussion and puts forward to establish emergency command system, emergency guarantee system and the underground explosion emergency plan ", "the subway epidemic emergency plan", "the subway fire emergency plan" and "subway fire interval rescue plan" and so on a series of emergency plan proposal, the gb "subway design specification of GB50157-2003 also noted for subway fire prevention and rescue.
For the subway security is concerned, only focus on the emergency treatment is not enough, the disaster treatment and rescue need some time to reach the designated position is carried out, so as to passengers, in the relief work in place before, appropriate prevention facilities or equipment guarantee their safety or the drum for escape time appear very important, will fire, explosion hit even biological attack separation or limit in the area, to prevent its to another area spread or affected, the subway construction security is concerned, can will subway station space and subway space into two partitions, in these two interval to adopt effective security space structure, can will take place in subway station (subway) of the disaster and the subway (subway) effectively separated.
Using suitable for metro rail transit and have fire.bomb blast security safety glass system is to solve the separation problem effective plan, the security glass system can keep the original subway station fully building exterior, on the function increase crisis time personnel safety protection.
Security glass system
Have fire prevention, prevent explosive function of security glass system mainly applied to partition partition, for fire is concerned, its role is to will stop in a particular area, prevent fire in different between the region spread, and can effectively cut off the penetration of the smoke, for explosive speaking, security glass system can block and absorption explosion wave, and stop high-speed splash crushing material, so to have safeguard passenger safety, for passengers escape buy time prevention function, typical security system consists of glass with fire, prevent explosive function of security glass and form a complete set of supporting frame.
Security glass fire separation
The subway is fire, earthquake, man-made disasters, etc more than ten kinds of disasters, but most fire accident, and casualties and economic loss is the most serious, so the subway to prevent disaster usually put the fire in the main position, the subway design specification of GB50157-2003 and on the security problems puts forward the "prevention first, extinguish combined with prevention," the guidelines, security glass fire prevention function for the implementation of this policy provides the solution plan.
Security glass explosion isolation
With the rise of China's ethnic separatist forces, the emergence of illegal religious groups and social instability increased in the increasing spread of the global explosion of terrorist activities today, it is difficult to independence of their body, the explosives as the primary means of subway terrorist activities.First, high explosives, technical content, more and more destructive power, subway disaster prevention efforts not only concerned about the fire problem, the key issues of anti-explosion is also a subway disaster prevention, it must be effective means of isolation, security glass with high strength andanti-flexible, fully blocked and absorbed the blast, and because of its high strength properties, it has good resistance to heavy impact performance, high-speed objects that can withstand the explosion splash, to achieve well-separated features, on the other hand, the mezzanine securityglass monolithic fire-resistant glass substrate at the same time with a good fire performance.
Supporting steel framework profiles
As a system, not only the security glass with each fire, explosion-proof ability, the supporting framework of profiles with each performance, otherwise, framework, once lost a supporting role, security glass will also be due to loss of support can not provide well-performance, on the other hand, the subway station as a flow-intensive activities in public places, matching profiles must have the appearance of fine quality, to meet the profile of these conditions is only forming a steel frame profiles, the current domestic and foreign production of suchtypes of steel sections abroad the the Italian foter, Switzerland's janson domestic Guangdong Golden glass Technologies Limited. As a rising star of the production of cold-formed steel sections, Guangdong Golden Glass Technologies Limited absorbed the design advantages of the foreign steel profiles and production technology at the same time, combined with its own technology, according to the design of anti-raw and use a cold roll forming process of the production the steel frame profiles with fire, and the superiority of anti-explosion, and the appearance of fine appearance.
