1. Inspection Items: A comprehensive inspection of buildings, structures, finishes, and equipment to establish and improve the quality档案 of the property, and to assess the property's quality.
2. Application Scope: Suitable for buildings and houses requiring comprehensive inspections.
3. Inspection Content and Process: The main inspection parameters for residential structural safety assessment include: inclination, settlement, cracks, foundation and base, masonry structural components, wooden structural components, concrete structural components, and steel structural components, etc. The detection of these parameters is generally conducted on-site.
4. Non-site inspection items:
During concrete structural component testing, the concrete core drilling method is used to test the concrete strength.
b. In structural steel component testing, the tensile strength test method is used to measure the tensile strength of steel specimens, and the bending strength test method is employed to assess the bending deformation capability of steel specimens.
c. Wood structural component testing includes tensile, compressive, and shear strength tests along the grain, bending strength and modulus of elasticity tests, and perpendicular to grain compressive strength tests.
5. Inspection Content Process:
① Investigate the historical evolution, architectural style, structural system, and other relevant information regarding the construction, use, and renovation of the property.
② Establish general layout, building plans, elevations, sections, structural plans, and cross-sections of main components.
③ Conduct sampling tests on the performance of load-bearing structural materials for the building. The number and locations of the sampled components should comply with relevant standards. The sampling locations should include representative damaged components.
④ Building Structure Safety Assessment - Inspects the integrity of the building structure, decoration, and equipment, etc., analyzes the extent of damage, and identifies the causes of damage.
⑤ Structural safety assessment for buildings, detecting the current state of house tilt and uneven settlement.
⑥ Based on the measured mechanical properties of the building structure materials, establish a reasonable calculation model according to the existing loads, usage conditions, and building structural system, and verify the current bearing capacity of the building.
⑦ Based on the measured mechanical properties of the building structure materials, in accordance with the existing loading conditions and the building structural system, utilizing the regional seismic response spectrum characteristics, establish a reasonable calculation model. Verify the current seismic resistance of the building and review the seismic structural measures.
⑧ Inspect the operational status of the building equipment. Comprehensive quality inspection plans and reports for building construction must be submitted to the municipal building quality inspection center for technical review in accordance with regulations.
