Steel structure construction

Construction quality control in steel structure engineering is an important link to ensure the safety, reliability and compliance with design requirements of the project. The following are some key points of construction quality control in steel structure engineering:

Material quality control:

Steel inspection: Acceptance of structural steel to check whether its quality, marking, specifications, strength, etc. meet the design requirements and related standards.

Welding material inspection: Check the quality and qualification of welding materials to ensure the quality of welding seams.

Coating quality: Corrosion resistant coatings and hot dip zinc coatings are checked to ensure compliance with specifications.

Welding quality control:

Welder Qualification: Check welders' qualifications and certificates to ensure they have the appropriate welding skills.

Welding process: Check the welding process procedures to ensure that the welding process is carried out in accordance with the specifications.

Weld appearance: Check the appearance of the weld to ensure welding quality and avoid defects such as pores and cracks.

Structure size and geometry control:

Size measurement: The size of the component is measured to ensure that it meets the design requirements.

Geometry: Check the geometry of the structure to ensure that it meets the design requirements and avoids deviation and deformation.

Support and foundation control:

Support installation: Check the installation position and direction of the support to ensure that the support is stable and meets design requirements.

Foundation quality: Check the construction process and quality of the foundation to ensure that the foundation meets the design requirements.

Fire prevention measures:

Fireproof coating: Check the construction quality of fireproof coating to ensure that it is evenly coated and meets the requirements of the code.

Fire sealing: Check the installation quality of fire insulation materials to ensure their integrity and effectiveness.

Detection and testing:

Non-destructive testing: ultrasonic, magnetic powder, radiation and other methods can be used for non-destructive testing of welds to ensure welding quality.

Load test: Load test is performed on the installed structure to verify its bearing capacity and stability.

Documents and records:

Quality documentation: Ensure that all construction quality related documents, drawings, specifications, etc. are complete, record the construction process and test results.

Quality report: Prepare construction quality report to record all aspects of construction quality in detail for subsequent review and acceptance.

Safety control:

Safety management: Implement safety management measures to ensure safety in the construction process and prevent accidents from causing damage to the structure.

The above control points need to be implemented according to the specific steel structure construction project, design requirements and relevant regulations. Reasonable construction quality control is helpful to ensure the safety, stability and durability of steel structure engineering.
