At present, most of the exterior Windows of high-rise buildings adopt the hollow glass window of bridge aluminum to meet the air tight, heat preservation and waterproof function of the upper window design. In 2014, the new "fire prevention code for building design" gb50016-2014 provided the following requirements for more than 54 meters of residential buildings:

    A residential building with a height of more than 54m shall have one room per household to meet the following requirements:

    1. It should be set up by the external wall, and it should be set up to open the outer window;

    The fire resistance limit of the inside and outside walls should not be less than 1.00h. The door of this room should adopt the class b fire door, and the outer window should have fire-proof integrity not less than 1.00h.

    At present can meet fire resistance 1 hour fire window manufacturer, basically is steel frame add compound or grouting glass. Since the steel frame is not extruded, it can not meet the requirement of air tightness, and the window of ordinary bridge aluminum is less than one hour in refractory time. So for this kind of situation I companies invest manpower and material resources and specialized field on the basis of the broken bridge aluminum window combined with the characteristics of the original steel fire window fire, developed a patent product of our company, can reach 1 hour broken bridge aluminum refractory integrity fire window, has been entrusted inspection. This product has the function of energy saving, sound insulation, noise proof, dustproof, waterproof and so on. It also has the following advantages:

    1. It is the key point for the fireproof window of the bridge aluminum fire window to build a firewall in the aluminum profile of the bridge with steel lining and fill the cavity with fireclay. It can reach the fireproof time of the steel window, and maintain the original airtight waterproof requirements of the profile.

    2, USES the monolithic cesiumic potassium flameproof glass and ordinary tempered glass hollow fireproof glass (2 bo a cavity or 3 bo two cavities) or hollow fire low-e glass, have the effect of fire protection and energy conservation; Fireproof mud (patented product) is used between glass and profile to prevent fire and heat insulation.

    3. It meets the requirements of fire protection and energy conservation, and avoids the drawbacks of the original fireproof window composite glass and grouting glass, which are used to make the outer wall and foaming.

    4, on the basis of the original material added with fire yan mouth, fireproof glue slot, this also is "nine" Ann JA65 series profiles of the main features, is the time to refractory are two key points in patent protection;

    5. The fire-proof expansion adhesive set is used to seal the fire without fire, and the expansion of the rubber strip after the fire can prevent the spreading of the fire.
