Metal Frame Structure ASTM A36 Prefabricated Warehouse Buildings In Steel

Prefabricated steel warehouse building

Steel structure components are mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Steel structure factory buildings, warehouses, office buildings, residences and other building components or components are usually connected by welding seams, bolts or rivets.Steel structure building system has the advantage of light deadweight, factory production, fast installation, short construction period, good seismic performance, investment recovery faster, less environmental pollution and other comprehensive advantages, compared with a reinforced concrete structure, is more in the "high, big, light" three aspects of the development of unique advantages, globally, especially in developed countries and regions, the steel structure in the rational, widely used in the field of construction engineering.

How to do a good job of steel structure warehouse fire prevention measures

1,Shielding

The steel structure is arranged in the wall or ceiling composed of refractory materials, or the component is packed in the gap between the two walls. As long as a little refractory material is added or not added, the purpose of fire prevention can be achieved.This is a more economical method of fire prevention.

2.Layer

It is in the appearance of the steel structure to add a layer, can be cast molding, can also use spraying method.Cast-in-place solid concrete layers are usually reinforced with wire mesh or steel reinforcement to limit shrinkage cracks and ensure shell strength.Spraying can be applied to the surface of steel structures at the construction site to form a protective coating with sand pumps, which may be lime cement or gypsum mortar, or may be mixed with perlite or asbestos.At the same time the layer also can use perlite, asbestos, gesso or asbestos cement, light concrete make it prefabricated board, use adhesive, nail, bolt to be fixed on steel structure.

3. Expansive materials

The use of steel structure fire retardant coating to protect members, this method has the advantages of good fire insulation performance, construction is not restricted by steel structure geometry, generally do not need to add facilities, and the coating quality is light, there are certain beautiful decorative effect, belongs to the modern fire technology measures.

4. Fill with water (water jacket)

Water filling in hollow steel structure is an effective protection against fire.This method can make the steel structure in the fire to maintain a low temperature, water circulation in the steel structure, absorbing the heat of the material itself.The heated water can be recirculated after cooling, or replaced by cool water channeled through pipes.
