As a kind of building materials commonly used in modern times, steel structure should be handled well in daily fire protection work when we are in use. Here's a look.we provide steel structure house,you can know it.
1. Adding an outer layer on the surface of the steel structure can be cast in situ or sprayed.
In order to limit shrinkage cracks and ensure the strength of the shell, the cast-in-situ solid concrete outer layer is usually strengthened by steel wire mesh or reinforcing bar.
Spraying method can coat steel structure surface with sand pump to form protective layer. The sand pump can be lime cement or gypsum mortar, or can be 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 to make prefabricated slabs, using adhesives, nails, bolts fixed on the steel structure.
How to Prevent Fire in Steel Workshop
2. Water filling in hollow steel structure
This is an effective fire protection measure. This method can keep the steel structure at a lower temperature in the fire, circulate water in the steel structure, and absorb the heat of the material itself. Heated water can be recirculated after cooling, or cooled water can be introduced by pipes to replace heated water.
3. Adding expansive materials.
This method has many advantages, such as good fireproof and heat insulation performance, construction not limited by geometric shape of steel structure, etc. Generally, it does not need to add auxiliary facilities, and the quality of coating is light, and it also has a certain aesthetic decorative effect. It belongs to modern advanced fire prevention technology measures.
At present, there are more and more high-rise steel structure buildings, especially some high-rise buildings, which use steel structure materials more widely.
Once a fire accident happens in a high-rise building, the fire can not be extinguished in a short time. This requires us to increase the fire protection of building materials in architectural design, in order to enhance its fire resistance limit, and to formulate the necessary emergency plan within the building to reduce casualties and property losses.
The steel structure is set in the wall or roof composed of refractory materials, or the component is enclosed in the gap between two walls, so long as a little refractory material is added or not increased, the purpose of fire prevention can be achieved. This is an economical way.
Generally, when we use steel structure, we should not only do a good job of daily fire protection, but also check according to the use environment and make good use of it.
