The service life of rural earthen wall houses, and the life of rural brick concrete houses

Well-maintained words for thirty or forty years.

A long time ago, the countryside began to build houses with earthen walls, and it was not until the end of the eighties that it was gradually mixed with stone, wood and bricks.

and other new building structures.

Substitute band. In the countryside, mud-walled houses are built by mixing mud and straw.

The life span of brick-concrete structure is 50 years. The specific explanation is as follows.

1. Brick-concrete structure refers to the wall of the vertical load-bearing structure in the building. Brick-concrete structures are generally used in single-storey or low-rise houses, mainly relying on the mutual friction of bricks and the stiffness resistance of materials, of course, bricks can not be compared with concrete, but as long as appropriate structural measures are taken to resist the smaller ** is not much of a problem.

2. The brick-concrete structure is a kind of mixed structure, which is to use the brick wall to bear the load. The brick-concrete structure has strong chemical stability and atmospheric stability, is not easy to react with other chemicals, has stable durability, and is suitable for use in buildings with high requirements for service life.

3. The brick wall and the inner frame are mixed load-bearing, and the internal beams and columns are used instead of the wall load-bearing. The sound insulation effect of brick-concrete structure is medium, and the sound insulation effect of frame structure depends on the choice of partition material, the sound insulation effect of some advanced partition materials is better than that of brick-concrete structure, and the sound insulation effect of ordinary partition materials, such as cement hollow core slabs and the like, is worse than that of brick-concrete structure.

The service life is the physical wear and tear of the physical form of the house under the action of physical and chemical factors in the outside world; The number of years during which a dwelling can be maintained in normal use under physical wear and tear is called the useful life. The service life is determined by the structure and quality of the dwelling. The structural type of a dwelling is mainly divided by the materials used in its load-bearing structure.

At present, most of the commercial houses are brick-concrete structure, and the main load-bearing structure of brick-concrete structure is clay brick and a small part of reinforced concrete components, which is only suitable for multi-storey residences, and its advantages are low cost, good thermal insulation and thermal insulation performance, and are convenient for construction. The disadvantage is that the opening and entry of the house are deeply restricted, the indoor pattern can not be changed in general, the wall structure occupies too much space, and the integrity and durability are poor. The depreciation life of a dwelling refers to the number of years of transfer of the value of the dwelling, which is determined by the socio-economic conditions in the process of use, and is also called the economic lifespan.

The useful life of a dwelling is generally greater than the depreciation life. The depreciation period of different building structures is stipulated by the state: 60 years for reinforced concrete structures; 50 years of brick-concrete structure.
