Anonymous users2024-02-13The service life of the house is generally equivalent to the design life, but it also has a certain relationship with the use of the brick and concrete structure, and the 50 years of the brick-concrete structure is guaranteed, if there is no problem with the foundation. The peeling off of the wall skin is generally caused by the alkali activity of the original gray skin layer by the moisture part of the material, which can be repainted to solve, and it is necessary to pay attention to whether the load-bearing part of the brick is exposed and whether the brick has chalking. Considering that brick-concrete structure houses are generally not high-rise, combined with the location of the house itself, it may be demolished in a few years, and I personally think that the problem is not very big.

Anonymous users2024-02-12You're a good guy. But let me explain to you, the structural design service life of residential buildings in China is 50 years, which does not mean that you can't live after 50, and the design and construction unit is only responsible for this building for 50 years, for example, if you buy a computer, the repair period is one year, not that the computer can only be used for one year. The problem of the wall skin falling off you mentioned is not that the waterproofing is not done well, and it has little to do with that.

Anonymous users2024-02-08The building life of the house depends on what structure the house belongs to, for example, the civil building adopts a brick and concrete structure, and the life span is about 50 years, and the large reinforced concrete structure building is about 60 years. The actual life of a building is closely related to many factors such as building materials, foundations, structural design and natural conditions. In the actual use of the cruise, weathering, corrosion, dripping and other conditions should also be taken into account, and some houses will slowly turn to dangerous buildings after 50-70 years of use.
The relevant age of the dwelling.
1. The design life is 50 years.
The upper limit of the design life of ordinary buildings in China is only 50 years, and the design life of ordinary residential, commercial and other buildings is 50 years as the upper limit, which means that the general fiber sales through the house needs to ensure that there are no quality problems that obviously endanger the safety of the building in at least 50 years.
2. Land use period.
The life of the building is the life of the land. The land use period of residential land is 70 years, and if the lease is renewed at the expiration date, it is basically possible to have the land use right all the time.
3. Actual service life.
According to the current life of concrete, there will generally be no quality problems of the main body of the building after 100 years of use. Therefore, the main body of the existing house should be able to be used for far more than 50 years of design life. Reinforced concrete can last for hundreds of years, but the pipes and wires in the construction of houses cannot last that long.
Therefore, the final service life of the house depends on the life of these infrastructure equipment in the building. But as long as it can be repaired and replaced, the general house can still effectively extend the service life.
4. The life span is also based on land acquisition.
If the land occupied by the house is subject to land acquisition, then the useful life of the house is considered to have expired. Of course, during the period of land use right ownership, the land can be expropriated and compensated accordingly. But if we don't renew the lease, then the house will be repossessed without compensation.
The age of the building.
The term of the right to use construction land stipulated by the current law in China is 70 years for residential land, 50 years for industrial land, 40 years for commercial land, and 50 years for comprehensive land. Sometimes developers will change the concept and sell houses under the banner of 70 years of use, but they are not wrong because they are saying that the state-owned land of the residential plot has a 70-year life of use.
