Specific sub items of steel structure engineering

Steel structure engineering covers multiple specific sub items, mainly including the following 13 items:

1. Welding of steel structures.

2. Fastener connection.

3. Processing of steel components.

4. Assembly and pre assembly of steel components.

5. Installation of single-layer steel structure.

6. Installation of multi-layer and high-rise steel structures.

7. Space steel structure fabrication.

8. Installation of spatial steel structures.

9. Pressed metal plate.

10. Anti corrosion coating application.

11. Fireproof coating application.

12. Installation of gutters.

13. Installation of rain shelter.

Next, we will explore the common forms of steel structure engineering. Due to its light weight and convenient construction, steel structures have been widely used in various fields such as large factories, venues, and super high-rise buildings. Among them, the more common five forms include: steel frame structure for heavy industrial plants, steel grid structure for large-span public buildings, core tube frame structure for super high-rise buildings, steel truss structure for bridges, and composite steel frame structure for high-rise buildings.

1. Framework structure. In high-rise and super tall buildings, frame structures play an important role, consisting of interconnected frame beams and columns, providing stable support for the building.

2. Rack structure. The bent frame structure has been widely used in single story factories and industrial buildings. It is mainly composed of steel roof trusses or steel trusses, combined with other components, to form a stable structural system.

3. Steel frame structure. Steel frame structure is also a common form in single story industrial buildings. It is connected by steel columns and beams to form a strong load-bearing frame.

4. Grid structure. In public buildings with large open spaces, grid structures have been widely used. It is composed of steel or concrete columns continuously combined with standard members, and has excellent bearing capacity and stability.

5. Other special forms. In addition to the common forms of steel structures mentioned above, there are also some special forms of steel structures, such as large sports venues like the Bird's Nest, which demonstrate the unique charm and wide application prospects of steel structure engineering.

Next, we will delve into the construction process of steel structure engineering.

1. Careful preparation before construction. This includes gathering technical personnel for detailed design and planning, while ensuring the reasonable arrangement of temporary facilities, as well as coordination and communication at all stages.

2. Accurate construction layout. According to the design requirements, work closely with the civil engineering unit, carefully check and record key data such as elevation lines and axes, ensure that the height of the entity is consistent with the drawing, and minimize errors.

3. Rigorous foundation embedding. The size, length, and position details of the embedded bolts must be strictly checked and firmly fixed to lay a solid foundation for subsequent construction.

4. Thorough material processing and production. This process covers multiple steps such as cutting, layout, cutting, welding, rust removal, painting, and acceptance to ensure the quality and accuracy of the materials.

5. Fine installation of steel structures. Following the basic axis and elevation, the method of segmented lifting is adopted. First, the steel columns are lifted and calibrated for fixation, and then the steel beams are lifted to ensure the stability and accuracy of the overall structure.
