消防政令中规定了为了消防队安全、顺利地进行灭火活动而设定了排烟设备的基准(见图1)。另外,建筑基准法施行令中规定了排烟设备的标准,其主要目的是用于火灾初期避难时的排烟。图1排烟设备(消防排烟)示意图根据防火对象的规模及用途,有时要求消防排烟和建筑排烟这两方面的设置,一般是两种排烟兼用。然而,由于消防排烟和建筑排烟在技术标准上是有差异的,因此,如下所述,事实上,兼用在某些方面是不可行的。因此,针对消防排烟和建筑排烟兼用不可能的 The fire decree sets out the baseline of smoke extraction equipment for fire brigade safety and smooth fire fighting activities (see Figure 1). In addition, the Building Code of Conduct provides for the standard of smoke extraction equipment, the main purpose of which is for smoke evacuation during the initial evacuation of a fire. Figure 1 Schemes of Exhaust Equipment (Fire Exhaust) According to the size and purpose of the fire object, fire smoke exhaust and building exhaust are sometimes required to be set in two ways. Generally, two types of smoke exhaust are used together. However, since there are differences in technical standards between firefighting and building fume extraction, as described below, in fact, it is not feasible for some to be used in some aspects. Therefore, for fire smoke exhaust and building exhaust impossible
