Xiaoguan Industrial Building Factory Safety Structure Inspection and Report Procedures, Xiaoguan Factory Inspection Unit

Hauzen Industrial Building Factory Safety Structure Inspection and Reporting Process: The content of the factory inspection and appraisal includes settlement, tilt, cracks, masonry structural components, wooden structural components, foundation, concrete structural components, and steel structural components, etc. The detection of each parameter is generally conducted on-site. In the detection of steel structural components, the tensile strength test method is used to measure the tensile strength of steel specimens, and the bending strength test method is used to assess the bending deformation capability of steel specimens.

Summary of Xiaogan Factory Inspection Results
1. Suitable for light industrial workshops, the building is designed for non-corrosive environments, vibration loads, and high-temperature conditions.
2. The main structure is constructed using fully cast-in-place reinforced concrete, with the primary beams and columns arranged in accordance with the drawings.
3. The building of the Xiaoguan factory has no overall tilt and uneven settlement deformation, and the main components have no obvious quality defects affecting the bearing capacity.
4. The actual dimensions of the beams and columns in Xiaoguan's factory building match the design drawings.
5. The concrete estimated strength of the columns in the Xiaoguan factory is 14.4 MPa, and the estimated strength of the beams is 20.1 MPa.
6. The measured quantity and arrangement of steel rebars in beams and columns are consistent with the design drawings. Identification Conclusion: The structural calculation results show that the frame columns and beams have sufficient bearing capacity, meeting the requirements of the "Building Seismic Evaluation Standard"; the safety of the foundation, superstructure, and protective system reaches Grade A; the comprehensive safety level of the building is Grade A, and its structural safety meets the requirements for normal use, and no secondary structural safety inspection or evaluation is needed. Processing Suggestions: Ensure normal use and maintenance during the future use of the building; it is recommended to limit the floor loading of the factory building to less than 3.5 kN/m2. When the loading reaches this value, structural reinforcement should be carried out. Do not arbitrarily construct partition walls, add floors, or change the building's use function. When adding floors or changing use functions are necessary, entrust a qualified design unit to review the structure and propose treatment opinions. Considering the durability of the building, it is recommended to seal the visible temperature shrinkage cracks as soon as possible.

Purpose, Scope, and Content of Inspection and Appraisal
1. Purpose of Inspection and Identification: Determine the current safety status of the structure.
2. Scope of Inspection and Authentication: Includes foundation, superstructure, and protective systems.
3. Inspection and Appraisal Content: Assess the integrity of the building's structural system, structural selection, component layout, geometric dimensions of load-bearing components, reinforcement, and appearance, test the concrete strength, and verify the load-bearing capacity of structural components, in accordance with relevant standards and industry norms. Conclude the structural safety and propose related treatment recommendations.

The general process for factory auditing typically includes:

Engage a property assessment agency for on-site factory inspections and property evaluations.
2. The house inspection agency dispatches a house safety inspector for on-site surveys, conducting detailed inspections of the factory's usage history, structural system, and damage conditions.
3. On-site surveys can document the main structure and load-bearing components of the factory building through methods such as text, drawings, photos, or video recordings.
4. The mechanical property testing of factory building structural materials should be determined based on the necessity of structural load-bearing calculation.
5. As necessary, establish a calculation model based on the structural characteristics of the factory, and verify the safety reserve of the factory structure according to the actual mechanical properties of the structural materials, the applied loads, and the current regulations.
