Steel structure plant mainly refers to the main load-bearing components are composed of steel. It includes steel pillars, steel beams, steel structure foundation, steel roof truss (of course, the span of the workshop is large, which is basically steel structure roof truss), steel roof roof, note that the wall of steel structure can also be maintained by brick wall.
Because our country's steel output increases, many have begun to use the steel structure workshop, the concrete can also be divided into light and heavy steel structure workshop. Compared with other materials, steel structure has the following characteristics:
High strength and light weight
Although the density of steel than other building materials, but its strength is very high, the same stress, steel structure weight is small, can be made into a larger span structure.
Good plasticity, good toughness
The plasticity of steel is good, the structure will not break suddenly because of accidental overload or partial overload. The toughness of steel makes the structure more adaptable to dynamic load.
The internal structure of steel is uniform and isotropic. The actual working performance of the steel structure is in good agreement with the theoretical calculation results, so the reliability of the structure is high.
Due to the weldability of the steel, the connection of the steel structure is greatly simplified, which is suitable for the manufacture of various complex shapes.
Steel structure production, installation of high industrial degree
The production of steel structure is mainly in the specialized metal structure factory, so the production is simple and high precision. The components are delivered to the site for installation, with high degree of assembly, fast installation speed and short time limit.
Steel internal organization is very dense, when the use of welding, or even the use of rivets or bolts, are easy to achieve tight leakage.
When the surface temperature of the steel is within 150℃, the steel strength changes very little, so the steel structure is suitable for the hot workshop. When the temperature exceeds 150 ℃, its strength decreases obviously. When the temperature reaches 500-600t, the intensity is almost zero. Therefore, when a fire occurs, the fire resistance time of the steel structure is relatively short, and sudden collapse will occur. For steel structures with special requirements. Insulation and fire resistance measures should be taken.
Steel in humid environment, especially in corrosive medium environment is easy to rust, need regular maintenance, increase the maintenance cost.
