本讲谈谈建筑物的耐火等级和防火分隔问题。不少的工厂、仓库和民用建筑发生的火灾实例说明,在设计中没有根据生产、贮存物品的火灾危险性类别、使用性质、规模大小等选用相应耐火等级的建筑物和采取必要的防火分隔设施,而遭致火灾蔓延快、扑救困难,损失严重。如济南汽车制造总厂齿轮车间为多跨砖木结构厂房,耐火等级低,又没有采取有效的防火分隔设施,结果,紧贴车间的垃圾池中的可燃物起火,蔓延成灾,烧毁厂房7700多平方米和大批设备,损失150余万元。可见,在设计中,切实按照
This talk about the building fire rating and fire separation issues. The fire examples in many factories, warehouses and civil buildings show that there is no selection of fire-resistant buildings and the necessary fire separation facilities according to the type of fire hazard of production and storage of goods, the nature of use and the size of the buildings in the design , Which caused a rapid spread of fire, fighting difficulties, loss of serious. For example, the gear workshop of Jinan Automobile Manufacturing Plant is multi-span brick and wood structure workshop with low fire-resistant grade and no effective fire-proof separation facilities. As a result, combustibles in the rubbish pool near the workshop caught fire and spread to disaster and burned the plant 7700 Multi-square meters and a large number of equipment, loss of more than 150 million. Can be seen in the design, in strict accordance with
