Steel structure workshop how to do safety inspection

In industrial plant construction, people often choose steel structure. Due to the construction speed of the steel structure workshop, the steel structure is very strong and durable. The most important thing is that the steel structure building space is flexible, which is very suitable for industrial workshop and production workshop. However, the steel structure in the use of the process will inevitably appear problems, such as: steel structure joint cracking, corrosion, bolt joints loose and so on. These problems may seem small, but they do pose a great threat to the overall safety of steel plants. Therefore, the steel structure plant should be tested before the formal production and after the problem occurs.

I. Content of steel structure inspection and appraisal.

The inspection and appraisal of steel structure mainly includes the steel structure with special requirements such as material, component, connection and node defects, structural system, damage detection and safety, applicability, durability and seismic performance appraisal, such as steel structure after fire, steel structure fatigue inspection and appraisal, steel structure dynamic inspection and appraisal and so on.

2. Basic work content of on-site inspection.

Collect engineering geological survey reports, design drawings, calculation books, design changes, settlement observation records, construction records, material warranty, material inspection documents, as-built drawings, completion acceptance documents and other relevant materials; Understand the construction, use, damage and repair history of the building, such as construction, renovation, maintenance, changes in the use of the building, the use of conditions and changes in the use of the environment and whether disasters occur; Basic situation investigation and data verification. When there are construction drawings, on-site verification should be carried out; When there is no construction drawing, mapping drawing should be drawn according to the actual situation of the structure; Basic investigation. Environmental investigation of steel structure. Material performance testing. Test the node connection status. Structural damage testing. Structural deformation testing. When necessary, it can also carry out structural dynamic test and structural or component field load test.
