The main structural installation techniques and architectural features of steel structure projects

{1}. Main structural installation techniques for steel structure engineering
When using steel structure buildings in steel structure engineering, although the application of this structure has many advantages. However, during installation, cleaning work is required. For architects, introduce some of the main parts to be cleaned.
The steel structure house shot blasting machine, during the cleaning process, the electrically controlled adjustable roller conveyor sends the steel structure components or steel materials into the shot blasting area inside the cleaning chamber. All surfaces of the machine are hit and rubbed by dense shot from different coordinate directions, causing the rust layer and dirt on them to fall off, and the steel surface acquires a smooth and rough surface. The workpieces are loaded and unloaded on the roller conveyors at the entrances and exits on both sides of the cleaning chamber. The shot and rust dust that fall onto the steel are blown away by the purging device. The mixture of shot and dust that falls down is conveyed by the recovery screw to the hopper of the chamber body and collected at the lower part of the elevator by the longitudinal and transverse screw conveyors. Then it is lifted to the separator at the upper part of the machine. The pure shot after separation falls into the hopper of the separator and is recycled for shot blasting. Dust generated during shot blasting cleaning is sent to the dust removal system through the exhaust pipe. The purified clean air is discharged into the atmosphere, and the granular dust is captured and collected.
{2}. What are the characteristics of building steel structures?
1. The material is lightweight
The steel used in steel structures has and modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low. Therefore, under the same stress conditions, the cross-section of steel structures is small, their weight is light, and they are convenient for transportation and installation. It is suitable for large-span, high-height and heavy-load structures.
2. Steel has good toughness, excellent plasticity, uniform material and structure
It is suitable for bearing impact and dynamic loads and has excellent performance. The internal structure of steel is uniform and close to an isotropic homogeneous body. The actual working performance of the steel structure conforms to the calculation theory. Therefore, steel structures have properties.
3. Highly mechanized manufacturing and installation of steel structures
Steel structure design components are easy to manufacture in factories and assemble on site. The factory mechanical manufacturing of steel structure components features high production efficiency, on-site assembly and short construction period. Steel structure is a highly industrialized type of structure.
4. The steel structure has good sealing performance
Because the welded structure can be said to be sealed, it can be made into high-pressure vessels, large oil tanks, pressure pipes, etc. with good air tightness and water tightness.
5. Steel structures are not heat-resistant
When the temperature is below 150℃, the performance of steel changes very little. Therefore, steel structures are suitable for high-temperature workshops. However, when the surface of the structure is exposed to thermal radiation at approximately 150℃, insulation boards should be used for protection. When the temperature is between 300℃ and 400℃, the strength and elastic modulus of steel decrease significantly. When the temperature is approximately 600℃, the strength of steel tends to zero. In buildings with specific requirements, steel structures are protected with fire-resistant materials to enhance their grade.
6. Steel structures have poor corrosion resistance
Especially in damp and corrosive environments, it is very easy to rust. Generally, steel structures undergo rust removal, galvanization or painting treatment and are maintained regularly. For offshore platform structures in seawater, measures such as “zinc block anode protection” need to be taken to prevent corrosion.
7. Low-carbon, energy-saving and reusable: The demolition of steel structure buildings generates almost no construction waste, and the steel can be recycled.
