Steel structure

Steel structure construction is a complex and precise work, which requires strict planning and fine technical cooperation. The following are the general steps of steel structure construction:

Project preparation stage:

Design Review: Ensure that the engineering design is carefully reviewed prior to construction to understand the design intent, structural requirements, and construction details.

Prepare drawings and documents: Prepare construction drawings, bills of materials, method statements, and other necessary documents.

Site preparation:

Site levelling: Ensure that the construction site is levelling to facilitate the entry and exit and operation of construction equipment.

Infrastructure: If necessary, foundation treatment, foundation construction, etc.

Material preparation:

Steel warehousing: to ensure the quality of structural steel, acceptance and numbering of materials, properly stored in the warehouse.

Check other materials: Check other materials required for construction, such as welding materials, coating materials, etc.

Install temporary facilities:

Build construction site: Build temporary facilities according to needs, such as construction platform, safety protection facilities, etc.

Steel structure installation:

Lifting: The use of cranes or cranes to lift the components to the predetermined position.

Connection: connection between components, including welding, bolted connection, etc.

Adjustment: Horizontal and vertical adjustment of the installed components to ensure the accuracy and stability of the structure.

Fixed: The member is firmly fixed to the foundation or other supporting structure.

Welding and inspection:

Welding: Perform welding operations on the parts that need to be welded to ensure the quality of the weld.

Non-destructive testing: non-destructive testing, such as ultrasonic, X-ray testing, to ensure that the welding parts are free of defects.

Anti-corrosion treatment:

Coating construction: The construction of anti-corrosion coating to improve the corrosion resistance of the structure.

System installation:

Mechanical and electrical equipment: installation of mechanical and electrical equipment related to the building, such as ventilation system, electrical system, etc.

Pipeline installation: Installation of pipeline systems, including water supply pipes, drainage pipes, etc.

Finishing work:

Cleaning and arrangement: Clean up the construction site, arrange materials and equipment.

Acceptance and testing: carry out the acceptance of the structure and system, and test the operation of the equipment.

Completion and delivery:

Overall acceptance: carry out overall project acceptance to ensure that the project meets the design requirements.

Delivery: Complete all the procedures of the construction project and formally deliver it to the owner for use.

Care and maintenance:

Establish maintenance plan: In order to ensure the long-term stable operation of the structure, establish a regular maintenance plan and provide relevant recommendations to the owner.

Safety is always an important consideration throughout the construction process. The construction team needs to comply with the relevant safety regulations to ensure the safety of workers and reduce the occurrence of accidents.
