How to identify cracks in a house as a dilapidated house
Over time, a home can have a variety of problems, the most worrying of which is cracks. These cracks not only affect the aesthetics of the house, but more seriously, they can cause the house to become a dangerous house and threaten the lives of the occupants. So,Guangdong Fang 10How do you identify if a crack in a house has made a house a dilapidated one?
1. The location and shape of the crack.
Generally speaking, if cracks appear on load-bearing structures, such as beams, columns, etc., then special attention is required. Cracks in these places are most likely caused by over-load-bearing or uneven settlement of the foundation. In addition, special attention is also required if the crack takes the form of a penetrating one, i.e. extending from one side of the house to the other.
2. The width and depth of the crack.
The width and depth of the crack are also an important basis for judging whether it is a dilapidated house. If the crack width is more than 1 mm and the depth is more than 5 cm, special attention is required. These cracks are likely to be caused by over-bearing or uneven settlement of the foundation, and need to be identified by a professional housing appraisal agency.
3. The development trend of cracks.
In addition to the location, shape, width and depth of cracks, we also need to pay attention to the development trend of cracks. If the cracks are constantly expanding, or new cracks are constantly appearing, then it is likely that the bearing capacity of the house structure is insufficient, and it is necessary to ask a professional housing appraisal agency to identify it. About Guangdong Fangshi Testing and Identification***Introduction.
4. The overall condition of the house.
In addition to looking at the crack itself, we also need to look at the overall condition of the house. If there are multiple cracks in the house, or if there are other anomalies, such as cracked walls, leaking roofs, etc., then special attention is also required. These situations are likely to be a manifestation of insufficient bearing capacity of the housing structure, and it is necessary to ask a professional housing appraisal agency to conduct an appraisal.
Identification of cracks in the house.
1. Crack investigation.
Crack investigation is the first step in the identification of cracks in a house, which mainly includes the investigation of the distribution, direction, length, width and depth of cracks. Through observation and measurement, the nature and cause of the crack can be preliminarily determined. In addition, it is necessary to investigate information such as the design, construction, and use of the building in order to conduct a comprehensive analysis of the cracks.
2. Material testing.
Material testing is an important part of the identification of cracks in houses, mainly including the detection of concrete, mortar, bricks and other materials of buildings. By testing the strength, compression, tensile and other performance indicators of the material, you can judge whether the material meets the design requirements and whether there are problems such as aging and corrosion. In addition, it is necessary to test the mix ratio of materials and construction methods to further understand the cause of cracks.
3. Structural analysis.
Structural analysis is the structural analysis and calculation of buildings through computer modeling and advanced technology. Through structural analysis, it is possible to understand the stress distribution and deformation of the building, so as to determine whether the cracks are related to structural problems. In addition, structural analysis can provide technical support for subsequent repairs and reinforcements.
4. Environmental testing.
Environmental testing mainly includes the investigation and detection of the environment around the building, such as temperature, humidity, chemical substances, etc. Environmental factors can affect buildings, such as temperature changes that can cause cracks in concrete, chemicals that can corrode building materials, and more. Therefore, environmental testing is also one of the important contents of house crack identification.
5. Appraisal conclusions.
According to the above investigation and analysis results, the appraiser will give an appraisal conclusion, evaluate the nature, cause, and degree of harm of the crack, and put forward corresponding repair and reinforcement suggestions. The appraisal conclusion is the final result of the identification of cracks in the house, which can provide a basis for subsequent repair and reinforcement work.
To sum up, to identify whether a crack in a house has made a house a dangerous house, we need to consider multiple factors such as the location, shape, width and depth of the crack, the development trend, and the overall condition of the house. If you find that there is an abnormality, you must take measures in time, such as reinforcing the load-bearing structure, repairing the foundation, etc. At the same time, it is also necessary to regularly inspect and maintain the house to ensure the safety and stability of the house. If you can't determine whether the house is dilapidated, you can ask a professional housing appraisal agency to conduct an appraisal. They can evaluate the structure and bearing capacity of the house through professional detection and analysis methods, and give accurate identification results. Although it costs a certain amount of money to have an appraisal done by a professional agency, it is very necessary relative to the value and safety of the house.
