When we usually use steel structure, it will be loved by everyone because of its high-strength materials. Then when we use it, where are these characteristics reflected? Let's see next.
1. High mechanization of steel structure manufacturing and installation
The steel structure members are easy to be manufactured in the factory and assembled on the site. The mechanical manufacturing of steel structure components in the factory has the advantages of high precision, high production efficiency, fast site assembly speed and short construction period. Steel structure is a kind of structure with high degree of industrialization.
2. Steel structure is heat-resistant and not fire-resistant
When the temperature is below 150 ℃, the change of steel properties is very small. Therefore, the steel structure is suitable for the hot workshop, but when the structure surface is radiated by the heat of about 150 ℃, the heat insulation board should be used to protect it. At 300 ℃ - 400 ℃. The strength and modulus of elasticity of steel decreased significantly. When the temperature was about 600 ℃, the strength of steel tended to zero. In buildings with special fire protection requirements, the steel structure must be protected with refractory materials to improve the fire resistance rating.
3. High material strength and light weight
The steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the steel structure has small section, light self weight, convenient transportation and installation, suitable for the structure with large span, high height and heavy load.
4. Good sealing performance of steel structure
As the welding structure can be completely sealed, it can be used as a high-pressure vessel with good air tightness and water tightness, a large oil pool, a pressure pipeline, etc.
5. Steel has good toughness, plasticity, uniform material and high structural reliability
It is suitable for bearing impact and dynamic load and has good seismic performance. The internal structure of the steel is uniform, nearly isotropic. The actual working performance of steel structure accords with the calculation theory. So the reliability of steel structure is high.
6. Poor corrosion resistance of steel structure
Especially in the humid and corrosive medium environment, it is easy to rust. Generally, the steel structure shall be derusted, galvanized or coated, and shall be maintained regularly. For the offshore platform structure in seawater, special measures such as zinc block anode protection should be taken to prevent corrosion.
7. Low carbon, energy saving, green environmental protection, reusable
Demolition of steel structure buildings will hardly produce construction waste, and steel can be recycled.
The above is the use characteristics of steel structure introduced for you. Generally, when we use it, we should also choose building materials according to the use environment and so on, and make a good overall use.
