Under what circumstances do you need to carry out a safety inspection and identification of the hous

When one of the following situations occurs, the house should be tested and identified in accordance with the relevant regulations.

1. The house is obviously damaged, deformed or otherwise degraded due to improper use, aging and other reasons;

2. In the requirements of safe use, it is necessary to understand the structural status and safety of the house;

3. The influence of external action causes damage to the house (adjacent engineering construction: deep foundation pit excavation);

4. The house is intended to be changed in use, use conditions or use requirements;

5. The house is to be repaired, rebuilt (including but not limited to additional floors, intercalations, etc.), overall relocation, etc.;

6. Have objections to the quality of the house;

7. For the sake of building protection requirements, it is necessary to understand the working status of the house and the reliability of the target service period;

8. The house exceeds the design service life;

9. Or have other needs.

The house is everyone's habitat, and the housing safety appraisal is the only way to ensure the safe use of the house. Here we need our professional team, Guangzhou Huamei Testing has 30 years of testing experience, the national CNAS qualification certification authority. Huamei Testing has built thousands of square meters of material identification laboratories and imported 450 sets of top testing equipment to bring you professional test reports supported by accurate data.

1. The foundation and main structure of the house have obvious sinking, cracks, deformation, corrosion and other phenomena;

2. The house needs to continue to be used beyond the design service life;

3. Natural disasters and accidents such as fire and fire cause damage to the main structure of the house;

4. It is necessary to dismantle and modify the main body or load-bearing structure of the house, change the function of the house, or significantly increase the load of the house;

The quality and safety of the house can be appraised under the following circumstances: the house needs to be used beyond the design service life; The main body of the house needs to be demolished and reconstructed, or the load-bearing structure significantly increases the load of the house; The foundation and main structure of the house are obviously sinking, cracked, deformed or corroded; Natural disasters or accidents cause damage to the main structure of the house.

[Legal basis].Article 39 of the Regulations on the Quality Management of Construction Projects.

The construction of the reed liquid stroke buried tank to implement the quality warranty system. When the construction project contractor submits the project completion acceptance report to the construction unit, it shall issue a quality warranty certificate to the construction unit to accompany the construction unit. The warranty certificate, the warranty scope, warranty period and warranty responsibility of the construction project shall be clearly stated.

Article 42.

If the construction project needs to continue to be used after exceeding the reasonable service life, the property owner shall entrust a survey and design unit with the corresponding qualification level to appraisal, and take measures such as reinforcement and maintenance according to the appraisal results to redefine the use period.

Housing safety appraisal is a series of activities such as investigation, testing, analysis, verification and evaluation of the working performance and working status of the housing structure according to the relevant appraisal standards and specifications.

Housing safety appraisal should generally choose reliability appraisal, but for houses with obvious dangerous components or overall danger signs, hazard appraisal can be selected. In situations such as emergency appraisal, unified inspection of housing safety as stipulated by national laws and regulations, temporary housing needs to be extended, and safety problems found in usability appraisal, only safety appraisal can be selected. Routine inspection of use and maintenance, and when there are high comfort requirements, only usability appraisal can be selected.

Special appraisal should be carried out when there are special requirements for structural maintenance and transformation, durability damage affects the durability period, there is obvious vibration impact, and long-term monitoring is required. Houses that need to be used close to or beyond the design service life, houses that do not consider seismic fortification in the original design or require seismic fortification to increase the base width, and houses that need to change the use of the structure and the use environment, shall be subject to seismic appraisal.

There are several common types of identification

1. Reliability appraisal: technical activities such as investigation, testing, analysis, verification and evaluation of the safety and usability of existing industrial or civil buildings. Safety and brightness include bearing capacity and overall stability, and usability includes applicability and durability.

2. Safety appraisal: technical activities such as investigation, testing, calculation, analysis and evaluation of the structural bearing capacity and overall stability of existing industrial or civil buildings.

3. Usability appraisal: technical activities such as investigation, testing, analysis, calculation and evaluation of the applicability and durability of the existing industrial or civil building functions.

4. Seismic identification: by inspecting the design, construction quality and status quo of the existing building, and evaluating its safety under the action of the first according to the specified seismic fortification requirements.

5. Hazard identification: According to the results of investigation, testing and analysis, the hazard of the existing structure is evaluated in accordance with the specified standards and methods. The purpose is to determine the degree of danger of the house to be identified.

6. Special appraisal: Appraisal for a specific problem or a specific requirement of the building.

7. Emergency identification: In order to deal with emergencies, when receiving an early warning notice, the building shall be inspected and identified with the goal of eliminating potential safety hazards; It also refers to the emergency inspection and appraisal of the degree of damage to the building and its danger after the occurrence of an emergency, with the goal of risk removal.
