What is the installation method of steel structure?

Install the assembly bracket at the design position, and then hoist the grid members into blocks (or blocks) by crane to the aerial design position, and assemble them on the bracket. This method is suitable for high-strength bolted steel space truss or steel pipe space truss with bolted ball joints.

2, the overall installation method

Assemble the grid on the ground into a whole, and then lift it to the design position with lifting equipment to fix it. This construction method does not need a tall assembly bracket, has less aerial work, and is easy to ensure the welding quality, but requires heavy lifting equipment and complicated technology. Therefore, this method is suitable for steel grid structures with spherical joints.

Characteristics of steel structure

1, steel structure has poor corrosion resistance, especially in wet and corrosive medium environment, and it is easy to rust. Generally speaking, steel structures should be derusted, galvanized or coated, and maintained regularly.

2. The manufacturing and installation of steel structure is highly mechanized, and steel structure members are easy to be manufactured in factory and assembled on site. Factory mechanized manufacturing of steel structure members has high precision, high production efficiency, fast on-site assembly speed and short construction period.

3. The steel structure is heat-resistant and not fire-resistant. When the temperature is lower than 150℃, the properties of steel have little change. Therefore, the steel structure is suitable for high-temperature workshops, but when the radiation on the surface of the structure is about 150℃, it should be protected by heat insulation board. When the temperature is between 300℃ and 400℃, the strength and elastic modulus of steel decrease significantly, and when the temperature is around 600℃, the strength of steel tends to zero.

4. Steel has good toughness and plasticity, uniform material, high structural reliability, suitable for bearing impact and dynamic load, and good seismic performance. The internal structure of steel is uniform and close to isotropic isotropic body.
