December 15, afternoon and 34 points, the shopping center of Beijing xizhimen le of exterior wall thermal insulation material fires. The Beijing 119 command center immediately seconded four squadron, 21 firetrucks team to the scene saves, 16 minutes after the fire is out. Fire area of 20 square metre. Due to save and evacuation in time, and the scene caused no injuries.
For the cause of the fire, the twittering:PVC windows the fire was because someone le 8 layers collapsed in the tiantai burn money lead to kindled the exposed wires. That once in the tiantai workers fall to fall dead, a year after the family will come to the ShaoZhi memorial. The fire is probably because burn spirit money and cause. Otherwise the micro bo questioned xizhimen in feng shui problems, say the fire and the xizhimen about feng shui. But that evening, Beijing fire in the microwave issued a statement that said: a survey,aluminum windows is because in the installation of outdoor advertising LED screen construction work, installation workers at the mall east wall construction site grinding machine with Angle cutting Angle steel work process, searing Angle steel ignites wall outside heat preservation material elastic polyurethane (pu) in the cause.
15 day night, Beijing fire bulletin: related departments to fire accident-Shanghai person xizhimen champs elysees li advertising Co., LTD, Beijing branch manager ZhangJiePing, persons directly responsible-shandong show the installation Co., LTD DuJinLong three employees peace zhao, in accordance with the implementation of administrative detention 10 days; And the two le centre property companies and Shanghai champs elysees li advertising company Beijing branch, three units of the 50000 yuan respectively of a fine.
And together heat preservation material to blame, last year's Shanghai fire, heat preservation material makes this iniquity fire to the world shocking, Shanghai fire pain yet from the people heart completely wiped, Beijing xizhimen again raised the blaze, unqualified building heat preservation material to people left a serious psychological shadows. Society calls project traders in strict accordance with the national standards for building construction, but little imagine caused to construction external thermal insulation system not qualified reason is come from various aspects.
Many standard heat preservation material trapped embarrassed
The author found access relevant information, ministry of public security, housing and rural construction in 2009, and jointly "civil building exterior insulation system and exterior decoration fire prevention provisional regulation" (hereinafter referred to as, 46 article), requires "civil building outside heat preservation material combustion performance for A level, and appropriate should be no less than B2 class"; And after the fire in CCTV, and in the rapid development of urban real estate market rise and proliferation, 18 layer above of the high-rise building more and more serious fire situation, March 14, 2011, the ministry of public security fire station and issued an "on further clear civil building exterior insulation material fire supervision and management of the relevant requirements announcement" (hereinafter referred to as the no. 65), this notice requirements "civil exterior insulation material use standard shall not be lower than A level". Politics than out, still have to carry out, it makes the production heat preservation material manufacturers and responsible for checking the fire department is helpless.
According to experts ZhaoHongHan composite materials is introduced, the external wall thermal insulation material most often involves fire prevention level can be roughly divided into three levels: combustion performance for A level, the characteristics of this kind of material can be summarized as non-combustible, including rock wool, cotton, glass, ceramic, foamed glass bubble foamed cement, closed pore perlite; Combustion performance for B1 level, this kind of material can be summarized in the characteristics of burning, including the special treatment of extruded polystyrene (XPS) / special treatment of polyurethane (PU), phenol, powder polystyrene particles; Combustion performance for B2 class, the characteristics of this kind of material can be summarized as non-flammable, including the molding of polystyrene (EPS), extruded polystyrene (XPS), polyurethane (PU), polyethylene (PE), etc.
Grade A fire materials, actually now on the application situation of Beijing? A local production engineering company head says, if use level A fire materials, exterior cost will be increased by 180 to 200 yuan/square metre. According to China's energy saving heat insulation material association consultant ZhangDeXin introduces, this year level A heat preservation material rock wool market demand falls short of demand. "The current can be used in the external wall thermal insulation of rock wool capacity of 100000 tons, 1.84 million tons last year and the size of the market for external wall thermal insulation is far than gap.
