The following requirements are made for the fire integrity of fire resistant glass wall:
Requirements for fire resistant integrity of fire-resistant glass walls in atrium and doors and Windows of exterior walls of buildings: fireproof separation should be carried out in connected Spaces with the surrounding areas: When fireproof partition walls are used, the fire-resistant limit should not be less than 1.00h. When fire resistant glass wall is used, its fire resistance, heat insulation and fire integrity should not be less than 1.00h. When the fire integrity of non-insulating fire resistant glass wall is not less than 1.00h, automatic sprinkler system should be set up for protection. When fireproof shutter is used, its fire resistance limit should not be less than 3.00h. Doors and Windows connected to the atrium shall be class-A fire doors and Windows that can be closed by themselves in case of fire.
Commercial facilities such as restaurants and shops are connected through the covered pedestrian street, and buildings on both sides of the pedestrian street need to use the pedestrian street for safety evacuation. The following provisions should be met: For shops in buildings on both sides of the pedestrian street, the fire resistance limit of the envelope members facing the pedestrian street should not be lower than 1.00h, solid walls should be adopted, and the doors and Windows should be Class B fire doors and Windows. When fireproof glass walls (including doors and Windows) are used, their fire resistance, heat insulation and fire integrity should not be less than 1.00h. When non-insulating fire resistant glass walls (including doors and Windows) with fire integrity not less than 1.00h are used, closed automatic sprinkler system should be set up for protection.
Requirements for fire integrity of eaves: when it is really difficult to set a solid wall between the upper and lower openings, fire resistant glass walls can be set up, but the fire integrity of fireproof glass walls of high-rise buildings should not be less than 1.00h, and the fire integrity of fireproof glass walls of single and multi-storey buildings should not be less than 0.50h. The fire integrity of the exterior window should not be lower than the fire integrity requirements of the fireproof glass wall.
