Steel Hook High Strength, High Elastic Modulus Is Also High

Before the Steel Hook processing, by the construction staff to prepare the technical procedures, and by the chief engineer validation. Carefully check the process of preparation of the process, and do the processing of drawings and mutual trial work.

The processing of various materials and equipment required for inspection, process equipment should be consistent with the provisions of the process.

Steel components in the lofting process, to verify the number of steel and connectors, materials specifications, model, size, and then ingredients, marking lofting, sorting stacking.

The flange plate, web and end plate are cut and cut by CG1-100 semi-automatic cutting machine to avoid the phenomenon that the steel plate is not straight and the missing edge is broken. The rib plate and the rigid supporting plate are cut with the shearing machine ; Profiles with manual cutting or grinding machine cutting.

The connection between the steel member and the connecting member is by means of high strength bolts. Aperture position, size, require a higher degree of accuracy. Drilling holes are used.

Before assembly, the parts should be corrected, the thicker steel plate can be used for pressure or flame heating correction.

The Steel Hook is corrected by the flange straightening machine.

Component assembly should be based on its structure, welding methods and welding sequence to determine a reasonable assembly sequence. To reduce welding deformation.

1 material strength is high, its own light weight

Steel strength is high, elastic modulus is also high. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the Steel Hook of the small cross-section, light weight, easy to transport and installation, suitable for large span, high height, Structure.

2, steel toughness, good plasticity, uniform material, high structural reliability

Suitable for impact and dynamic load, with good seismic performance. The internal structure of the steel is uniform and is close to the isotropic homogeneous body. The actual working performance of Steel Hook is more consistent with the calculation theory. So the Steel Hook is highly reliable.

3, steel construction and installation of a high degree of mechanization

The Steel Hook is easy to manufacture in the factory, site assembly. Factory mechanized Steel Hook components of high precision, high production efficiency, site assembly fast, short duration. Steel Hook is the highest degree of industrialization of a structure.

4, Steel Hook sealing performance

As the welding structure can be completely sealed, can be made airtight, watertight are good high-pressure containers, large oil pools, pressure pipes and so on.

5, steel heat is not refractory

When the temperature below 150 ℃, the steel properties change is very small. So the Steel Hook for the hot workshop, but the structural surface of about 150 ℃ by the heat radiation, to be used to protect the insulation board. The temperature of 300 ℃ -400 ℃. Steel strength and elastic modulus were significantly decreased, the temperature at about 600 ℃, the strength of steel tends to zero. In buildings with special fire protection requirements, the Steel Hook must be protected with refractory material to improve the fire rating.

6, steel corrosion resistance is poor

Especially in the environment and the corrosive media environment, easy to rust. General Steel Hook to rust, zinc or paint, and to regular maintenance. On the seawater in the offshore platform structure, broadcast using "zinc block anode protection" and other special measures to be anti-corrosion.
