Hainan Steel teach you: fireproof steel construction purpose

In the structure of the building sideways, in recent years it has been building steel line to favor, so in a lot of building sideways, such as single, multi-layer, factories, warehouses, waiting rooms, etc. will be used.

Lounges such as the use of steel are very common, however, as the building materials steel structure housing the main surface of the fire and there are some drawbacks unavoidable, its mechanical properties such as yield point, tensile modulus of elasticity due to temperature etc. rises sharply, steel usually lose carrying capacity in high temperatures, change a lot of strain, leading steel columns, steel beams bent fire retardant coating results due to excessive deformation and can not continue to use.

Generally do not increase the protection of the fire resistance of the steel structure for 20 minutes or so, to make the steel to overcome the lack of information on fire prevention in the practical application, must be fireproof treatment, the aim is to improve the fire resistance of steel to the design specification limits, to prevent the rapid warming of steel in the fire deformed, its measures are diverse, taking different methods according to different circumstances, such as the use of thermal insulation, fire-resistant materials isolated from direct burning of steel, reduce the speed of heat transfer postponed speed steel temperature, but whether to take conservation methods, consistent with its principles, not the same as taking a different steel fire protection measures. So that in the event of harm, the protection of life and property safety of people as possible. Hainan Steel
