As time goes by, the usage of the factory building extends, and if larger equipment needs to be added inside, the factory's load-bearing capacity will inevitably be affected. This is when a factory load-bearing inspection is necessary. The purpose of the inspection is to determine if the building can withstand the additional weight from the large equipment and ensure the continued safe use of the factory. If the inspection results do not meet the required standards, it is imperative to reinforce the building to avoid safety hazards and ensure safe operation.


Principles for Factory Load-Bearing Inspection and Appraisal


Uniform load, concentrated load, and other load types, as well as their distribution, are collectively referred to as loading patterns.


2. When using equivalent loads, we should consider whether the change in loading patterns may affect the results of structural component tests. If it does, it is usually due to changes in deflection values and in the internal force diagrams.


3. If the calculation load diagrams of the existing structural components are consistent with the loading patterns of the tested structural components, this indicates that the operation of the structural components is relatively close to the actual situation. If the testing conditions are limited or if it's desired to make the testing more convenient, loading can be applied using loads, equivalents, and the like, without affecting the primary object of the test.


Moreover, if the deflection values under uniform loading and under equivalent concentrated loading are not consistent, in such cases, we can adopt the method of adding the number of concentrated loads to achieve the effect of eliminating or reducing these influences. For clearly identifiable influences, the test results can be corrected. However, if the discrepancy in the loading diagrams is not clear, no correction can be made, and it is not recommended to use the equivalent loading method in such situations.


The main content of the factory building load-bearing inspection and appraisal covers:


Inspect the overall structure of the factory on-site, as well as investigate the usage level, any historical renovations, architectural style, and related information.


2. Based on the understanding of the factory to be inspected, preliminary plans, elevations, sections, and cross-sections of main components, etc., are drawn up.


3. Conduct core extraction on the factory's load-bearing structure to assess the performance of the structural materials. Pay attention to the location and quantity of extraction to ensure compliance with relevant regulations, and extract components from representative damaged areas.


4. Inspect the factory for any tilting or uneven settlement conditions


5. Inspect the extent of damage to factory equipment, renovations, and internal structures, and provide a detailed analysis of the causes of the damage.


6. Conduct a detailed survey of the current usage, load-bearing capacity, and overall structure of the factory building to establish an accurate calculation model and verify the current load-bearing capacity of the building.


7. Inspecting the operation of all equipment in the testing facility.

8. Reports and proposals from inspections must be submitted to relevant departments for review. In addition to general factory quality estimations, particular attention should be paid to the quality of construction projects to establish a comprehensive factory quality档案, providing an objective evaluation of factory quality.
