Prevention of curtain wall fire
Fire prevention measure of exterior wall insulation materials is to improve the public external insulation materials cognitive level, scientific prevention. From the reality, it is impossible for people to completely deny its use in curtain wall buildings because some external insulation materials are combustible. In fact, the key lies in the use of safety standards. If improve the standard use of insulation materials in external wall, increase the supervision of insulation materials, complete fire extinguishing measures, improve safety awareness, the vast majority of the fire caused by external wall insulation materials can be prevented. At present, a large number of new buildings in China use organic external insulation materials. Their thermal insulation performance is better than most inorganic materials, which is the mainstream building thermal insulation materials.
But in terms of material performance, they have a low ignition point and it is flammable. If a large number of such inflammable insulation materials are wrapped in the building, they will inevitably leave fire hazards to the curtain wall structure. Therefore, relevant departments must strengthen the fire management of such buildings, and improve the public’s scientific understanding of these materials, so as to achieve scientific prevention. Second, strict construction site management, eliminate safety risks. A domestic statistical report points out that about 25% of the fire involving building thermal insulation materials occurred during the stacking of thermal insulation materials, 65% occurred in the laying process of thermal insulation materials, less than 10% occurred in the building put into use. It can be seen that the building wall insulation construction process is a high risk period of fire. The supervision department should strengthen the standardized management of the production enterprises of insulation material, curtain wall manufacturers and the building insulation material market, carry out the wall insulation system certification work, the introduction of permits, insurance and other systems, in order to improve the safety of building wall insulation. In the fire supervision and inspection, the fire department are required to ensure that each working face under construction have fire water, in order to prepare for the occurrence of fire to carry out self-rescue. Only strict construction site management can eliminate the hidden danger of fire safety to the maximum extent. Third, we will update and improve all kinds of fire fighting and rescue equipment to enhance our ability to tackle difficulties.
According to statistics, in recent years, China’s super high-rise buildings have reached more than 100, there are a number of construction. Combined with thermal insulation material in high-rise building external wall has a devastating fire, which are extremely hard fighting, characteristics of fire spreading way, fire fire department in accordance with the government planning and regional economic development actual situation, consciously acquire high spray fire engines, ladder truck, improve fire army emergency rescue and crucial capabilities, thus rapid fire of thermal insulation material for curtain wall. In short, the wide use of building exterior insulation materials, the building fire protection problem should be considered both inside the building fire, but also to consider the building external fire protection.
