The subway security system adopts security glass and security separation structure, and the security glass system suitable for subway rail transit with fire prevention and bomb prevention is a useful plan to deal with this separation problem.

It is very difficult to prevent subway disasters in advance, and the rescue operation after disasters is not easy. Long before the country carried out large-scale subway construction, the security of subway has become the focus of attention of some, construction and design units and the general public. Relevant personnel have conducted in-depth discussion and Discussion on the fire and explosion prevention of subway, and put forward the establishment of emergency command system The emergency assurance system and a series of emergency plans such as subway blasting emergency plan, subway epidemic emergency plan, subway fire emergency plan and subway fire interval rescue plan. The national standard code for design of subway gb50157-2003 also refers to the prevention and rescue of subway fire.

In terms of subway security, it is impossible to only pay attention to emergency treatment, and disaster treatment and rescue needs can be implemented at the right time. Therefore, for passengers, before rescue operations are in place, appropriate prevention equipment or equipment to ensure or snatch escape time for them is very important to separate or restrict fire, blasting assault and even biological assault in the area, To prevent it from extending or touching to another area, in terms of subway construction security, the subway station space and subway space can be divided into two zones, and the useful security separation structure can be adopted in these two zones to effectively separate the disaster occurring in the subway station (on the subway) from the disaster occurring on the subway (on the subway station).

The selection of security glass system suitable for subway rail transit and with fire and bomb protection is a useful plan to deal with this separation problem. The selection of security glass system can adhere to the original transparent construction appearance of subway station and increase personnel protection in crisis.

Security glass system:

The security glass system with the functions of fire prevention and explosive blasting shall be applied to partition. For fire, its effect is to block in specific areas, prevent the extension of fire between different areas, and effectively isolate the penetration of smoke. For explosive blasting, the security glass system can isolate and absorb blasting shock waves and block high-speed splashing broken substances, so it can ensure passengers, The typical security glass system is composed of security glass with the functions of fire prevention and anti explosive blasting and supporting structure.

Fire separation of security glass:

There are more than ten kinds of disasters in the subway, such as fire, earthquake and man-made disasters, but there are many fire accidents, and the casualties and economic losses are severe. Therefore, the subway disaster prevention and preparedness generally puts fire in an important position. The code for design of subway gb50157-2003 puts forward the guideline of "prevention first, prevention and elimination combined" for this security problem. The fire prevention function of security glass provides a treatment plan for the implementation of this policy.

Blasting isolation of security glass:

With the strength of our country, the appearance of illegal religious groups and the increase of social instability factors, it is difficult for our country to be alone in the increasing number of blasting terrorist activities. Explosive blasting, as one of the main methods of subway terrorist activities, has high technical content and increasing destructive power. Subway disaster prevention not only needs to pay great attention to fire, but also explosion-proof is the key issue of subway disaster prevention, Therefore, it is necessary to choose useful isolation methods. The security glass has high strength and obstruction function, which can fully obstruct and absorb the blasting shock wave. Moreover, due to its high strength function, it has excellent heavy object impact function, can resist the high-speed objects splashed during blasting, and complete the perfect separation function. On the other hand, the laminated security glass selects a single piece of fireproof glass as the substrate, so it has various excellent fire prevention functions together.

Supporting steel structure profile:

As a system, not only does the security glass need to have fire prevention and explosion-proof abilities, but also the supporting structural profiles need to have corresponding functions. Otherwise, once the structure loses the support effect, the security glass will not be able to provide indispensable functions due to the loss of support. On the other hand, as a public place full of people, the supporting profiles selected in the subway station should have exquisite appearance quality, The profiles meeting these conditions only use the steel structure profiles formed at one time. The steel structure profiles produced by one-time cold bending process have the superior functions of fire prevention and explosion-proof, and the appearance is exquisite and beautiful.
