钢结构作为现代常用来进行建材使用的一种，平时我们在进行使用时，应当做好日常的防火工作处理，下面来看下。
Steel structure, as a commonly used type of building material in modern times, should be properly treated for daily fire prevention during use. Let's take a look below.
1、在钢结构外表增加外包层，可以现浇成型，亦可喷涂。
1. Adding an outer layer on the surface of the steel structure can be cast in place or sprayed.
现浇成型的实体混凝土外包层通常用钢丝网或钢筋来加强，以限制收缩裂缝，并保证外壳的强度。
The outer layer of cast-in-place solid concrete is usually reinforced with steel wire mesh or steel bars to limit shrinkage cracks and ensure the strength of the shell.
喷涂法可以在施工现场对钢结构表面涂抹砂泵以形成保护层，砂泵可以是石灰水泥或是石膏砂浆，也可以掺入珍珠岩或石棉。同时外包层也可以用珍珠岩、石棉、石膏或石棉水泥、轻混凝土做成预制板，采用胶粘剂、钉子、螺栓固定在钢结构上。
Spraying method can apply sand pump on the surface of steel structure at the construction site to form a protective layer. The sand pump can be lime cement or gypsum mortar, or mixed with perlite or asbestos. At the same time, the outer layer can also be made of perlite, asbestos, gypsum or asbestos cement, light concrete, and fixed on the steel structure with adhesives, nails, bolts.

2、空心型钢结构内充水
2. Water filling inside hollow steel structures
这是抵御火灾有效的防护措施，这种方法能使钢结构在火灾中保持较低的温度、水在钢结构内循环、吸收材料本身受热的热量。受热的水经冷却后可以进行再循环、或由管道引入凉水来取代受热的水。
This is an effective protective measure against fire, which can keep the steel structure at a lower temperature during a fire, circulate water within the steel structure, and absorb the heat generated by the material itself. The heated water can be recycled after cooling or replaced by cold water introduced by pipelines.
