What is the role of the factory inspection and inspection report? Industrial plants refer to various types of industrial production and industrial buildings directly required for industrial production, including major industrial production houses and power for production and other ancillary buildings. Industrial plants are designed according to the requirements of the production process and mechanical equipment layout. With the development of society, the scale of production continues to expand, and the production process is more diverse and complex. Therefore, there are many types of industrial plants. According to the structure and composition, they are generally divided into the following categories: single-storey plants, which are generally It is mainly used in heavy industries such as metallurgy and machinery. It is characterized by large volume and heavy weight. The horizontal transportation is mainly in the workshop, and most of it is carried out by lifting transportation equipment and vehicles in the factory. In heavy industry enterprises, there are many rows of pillars and columns, and the pillars and crane beams are generally in the form of concrete or steel structures. Single-storey buildings have single-span and multi-span forms, and multi-span single-storey buildings are divided into high-rise buildings and unequal high-rise buildings. Multi-storey workshops are also common in the industrial sector. They are mainly in the form of concrete and steel structures. Under normal circumstances, large cranes are not installed, but equipment with relatively large loads will be installed. The multi-storey building with masonry structure is more applicable to light industry and handicraft industry, requiring relatively small equipment loads and no vibration during operation of the equipment.

First, the factory inspection and inspection report has any role - the inspection process of the factory inspection and inspection:
1. Use the core method to detect the concrete strength of beams and columns.
2. Use the steel bar detector to detect the steel bar configuration of the beam, plate and column and the thickness of the steel protective layer. At the same time, select the beam and column chisel to verify the diameter of the steel bar.
3. Detect the cross-sectional dimensions of reinforced concrete beams and columns and the thickness of the slab.
4. Detect the concrete carbonation depth of the component and whether the steel bar is corroded.
5. Intercept the steel bars in the components for the mechanical performance test of the steel bars.
6. Check whether the structural arrangement is reasonable, whether the component transmission force is direct or not.
7. Detect the axis size and height of the entire building.
8. Check whether the beams, plates, columns and other components of the whole building have cracks, and analyze the causes of the cracks, whether the cracks have caused damage to the structure.
9. Check whether the wall and frame column are set according to the requirements of the specification, and whether the wall is used to set the structural column and the ring beam according to the specifications.
10. Detect deformation, cracks and leakage of the envelope structure.
11. Use the core method to test the strength grade of the foundation concrete, check the foundation size, and check whether the foundation concrete has quality defects such as cracking and looseness.
12. Use the theodolite to check if the entire building is tilted.
13. Make structural safety appraisal of the building based on the test results and current national regulations.

Second, the factory inspection and inspection report has any effect - if the factory is structural damage, or damage to load-bearing components, such as plant cracks, plant settlement, plant tilt, etc., can not guarantee the safety of production and use, must be tested.
The procedures and procedures for the safety appraisal of the plant shall be carried out from bottom to top, from outside to inside and from floor to floor. First, identify the environment and drainage system in which the plant is located, and then identify the exterior wall and appearance of the plant, then identify the aisle, stairwell, and then identify the interior, and finally identify the roofing system.
After the safety appraisal of the plant, the level of the plant can be obtained. How is the standard for the safety appraisal of the plant divided?
Class A: The structural bearing capacity can meet the requirements of normal use, no dangerous points are found, and the structure of the plant is safe.
Grade B: The structural bearing capacity can basically meet the requirements of normal use, and individual structural members are in a dangerous state, but do not affect the main structure and basically meet the requirements of normal use.
Class C: The bearing capacity of some load-bearing structures cannot meet the requirements of normal use, and local dangers may occur, which constitutes a partially dangerous house.
Class D: The bearing capacity of the load-bearing structure can no longer meet the requirements of normal use, and the whole plant has a dangerous situation, which constitutes a whole dangerous building. The results of the plant safety appraisal can provide suggestions for subsequent reconstruction and reconstruction. If major safety hazards are found during the appraisal process, the owner should immediately report the corresponding reinforcement measures.

3. What is the role of the inspection report of the factory inspection and inspection? There are many reasons for the cracks in the reinforced concrete houses with cracks or structural cracks. The safety of the buildings is also very important. Only the houses are correctly judged. The structural stress state and the influence of the crack on the structure can be used for the maintenance and reinforcement of the component. Among them, structural cracks have the greatest impact on the safety of houses, which fundamentally determines the structural stress of the house, the bearing capacity of the house and the possible damage of the house. Non-structural cracks have little relative impact, and are often formed by self-stress. They have little effect on the bearing capacity of the building structure and can be repaired and reinforced according to relevant needs.
1. Identifying the mechanical properties of structural cracks Structural cracks are divided into two forms: brittle fractures and plastic fractures. The occurrence of brittle fractures is abrupt. Once the impact on the entire structure of the house is large, it will cause damage to the house. Therefore, in the process of house safety inspection, it is necessary to check the places where brittle fractures are likely to occur, and find problems in time. Thereby, the reinforcement is carried out in advance to prevent the occurrence of cracks. Plastic failure cracks are less dangerous than brittle fractures, and there are signs of deformation or cracks in advance, which can be properly remedied according to the situation. For the plastic fracture crack, in the process of testing, the crack can be tested according to the position, length, depth, etc. If the crack does not expand, and the maximum crack does not exceed the specified value, then repair can be omitted.
2. Identifying the future development trend of cracks According to their expansion trend, cracks can be divided into: stable cracks, active cracks and development cracks. Under the action of long-term load, cracks are inevitable. As long as the cracks are stable and the width, depth and length meet the requirements of the requirements, there is no great danger. The structure of the house can be considered safe. However, if the crack is continuously expanded, it may affect the structure of the house. Therefore, it is necessary to carry out the necessary repair measures in time. When conducting house safety appraisal and testing, it is necessary to use appropriate testing tools to fully analyze the development trend of cracks, so as to accurately judge the nature of cracks and guide related repair work.
3. Judging the deformation measurement of the structural deformation structure of reinforced concrete members should focus on the detection of suspicious signs or the weakness of the structure itself. When measuring the deformation of the building structure, the maximum deflection and displacement of the building structure must be measured. At the same time, the structural deformation measurement should also be combined with the crack measurement. If the structural deformation is too large, it is likely to produce corresponding cracks, and too large cracks will cause the building structure to deform. Therefore, the deformation situation is an important indicator reflecting the stability of the housing structure, and is also an important part of the housing safety appraisal.

4. What is the role of the factory inspection and inspection report? The company undertakes the following national business scope:
1. The house's performance appraisal before changing the use, increasing the load, changing the structure of the house, and increasing the number of floors.
2, the project quality, structural safety, component durability and usability have doubts and verification.
II. The safety appraisal of surrounding buildings includes the safety appraisal of subways, tunnels, real estate, civil works, foundation pits, civil air defense, bridges, rivers and other constructions. The evidence preservation and safety of the surrounding houses are graded before construction; After the construction, the damage degree of the house and the cause of the damage are assessed, and reasonable reinforcement and repair suggestions are proposed for the damage caused.
III: Structural safety assessment after damage to the house The damage to the structure of the house caused by accidents such as rain, snow, and typhoon impact. Our company is based on the original design requirements, current national standards, and structural safety after the damage (loss) of the house. Sex, usability and degree of damage are assessed, and reasonable and effective repair and reinforcement treatment recommendations are given.
A factory building is a house that is mainly used for industrial manufacturing, production, assembly, maintenance, testing, etc.
