采用钢结构防火涂料保护构件，这种方法具有防火隔热性能好、施工不受钢结构几何形体限制等优点，一般不需要添加辅助设施，且涂层质量轻，还有一定的美观装饰作用，属于现代的先进防火技术措施。目前，高层钢结构建筑日趋增多，尤其是一些高层建筑，采用钢结构材料更为广泛。高层建筑一旦发生火灾事故，火不是在短时间内就能扑灭的，这就要求我们在建筑设计时，加大对建筑材料的防火保护，以增强其耐火极限，并在建筑内部制订必要的应急方案，以减少人员伤亡和财产损失。
The use of steel structure fireproof coating to protect components has the advantages of good fire and insulation performance, and construction is not limited by the geometric shape of the steel structure. Generally, auxiliary facilities do not need to be added, and the coating quality is light, with a certain aesthetic decorative effect. It belongs to modern advanced fire prevention technology measures. At present, there is an increasing number of high-rise steel structures, especially some high-rise buildings that use steel structural materials more widely. Once a fire accident occurs in a high-rise building, the fire cannot be extinguished in a short period of time. This requires us to increase the fire protection of building materials in building design to enhance their fire resistance limit, and to develop necessary emergency plans inside the building to reduce casualties and property losses.
4、屏蔽。
4. Shielding.
钢结构设置在耐火材料组成的墙体或顶棚内，或将构件包藏在两片墙之间的空隙里，只要增加少许耐火材料或不增加即能达到防火的目的。这是一种经济的方式方法。
Steel structures are installed in walls or ceilings composed of refractory materials, or components are enclosed in the gaps between two walls. As long as a small amount of refractory material is added or not added, the purpose of fire prevention can be achieved. This is an economic approach.
一般我们在对钢结构进行使用时，不仅要做好日常的防火工作处理
Generally, when using steel structures, we not only need to do a good job in daily fire prevention work
