What kind of house is considered a dilapidated house, how big a crack is

Self-built houses in rural areas? Your soil is too thick, there is no layered tamping, the contractor generally does not undertake earthworks, and the filling is probably because you did not fill the soil according to the law in order to save trouble.

Go to your local home appraisal. There are no formalities. Dilapidated houses are not dangerous. There was procedure. Not in danger.

Everyone's requirements for the building must be strong and firm, but some houses in the construction due to the quality of decoration problems, after living for a period of time, there will be cracks in the house, this crack will have a great impact on people's home life. So, how wide are the cracks in the house considered a dangerous house? What are the causes of cracks in houses?

Let's find out together.

Generally speaking, a crack width of more than 1mm in a house has been included in the scope of dangerous housing, and the house must be inspected to see if the crack has posed a danger to the house. However, if the crack is on the load-bearing wall of the house, it can be determined that the house is dangerous, because the dangerous house involves the safety of the housing institution, so it needs to be handed over to a qualified unit for inspection.

1. Cracks caused by foundation reasons.

The uneven settlement of the foundation is one of the causes of cracks in the house, and all the load of the house is transmitted to the foundation through the foundation, and the uneven settlement of the house foundation will occur under the action of stress diffusion. When the temperature of the upper layer of the foundation soil drops below 0 and the upper part begins to freeze, the moisture in the lower part will continue to rise due to the capillary action, and then ice crystals will form in the frozen layer, which is the expansion of the wall and finally cracks.

2. Cracks caused by temperature changes.

Changes in temperature can also cause cracks in the house, so you need to know that the heat expands and contracts.

It is the basic physical property of most objects.

Walls are no exception. Due to the uneven shrinkage of the wall due to the change in temperature, the wall will crack when the temperature stress exceeds the strength of the wall.

3. Cracks caused by materials.

Due to the implementation of measures for the protection of cultivated land in our country, clay solid bricks breed clay hollow bricks.

The use of blocks has been banned and restricted, so blocks are widely used. However, the cement block wall basically has cracks and water seepage, especially on the outer wall, which is quite obvious, and when the dry shrinkage rate of the block is large, the wall is prone to cracks.

The identification of dilapidated houses must meet the requirements of relevant standards.

If there is a crack in the house, it is necessary to find out the cause and what category it belongs to. You can ask a qualified third-party testing agency to test, and the relevant report certificate issued shall prevail.

Whether the cracks in the house are considered dangerous houses, mainly need to see whether the cracks of the house have a big impact on the overall house, if the impact is particularly large, then it can be regarded as a dangerous house, but it needs to be identified by professionals, and if there are cracks in the house, it must be repaired in time to avoid potential safety hazards.

In fact, I personally think that the house is cracked, of course, it is a dangerous house, because if there are some cracks in the house, it may have caused some architectural reasons for a long time, and some houses will collapse, so if this situation occurs, it should be repaired in time.

There are cracks in the house, if there are cracks in the load-bearing beams or load-bearing walls of the house, then it is a very dangerous situation, such a house must be considered a dangerous house, but if it is only because of the cracks in the wall and other factors, then it is very normal, and there is no need to worry.

Look at the cracks, such as on the load-bearing wall, which belongs to the dangerous house; Depending on the width of the crack, more than 1 mm may be tested for danger. Dilapidated houses involve structural safety, which needs to be determined by relevant qualified unit testing.

It's normal for cracks to appear in the house. After a long time in the house, there will be sinking, thermal expansion and contraction of the wall cracks, within a reasonable range is reasonable, most of the wall cracks are problems with the decorative layer, feedback to our wall paint. Such cracks are basically irregular.

The main reason for this problem is the cracking caused by the hollowing of the mortar underneath the decoration. Generally, the stability of the crack continues to increase is two years, and the diagonal crack is caused by the uneven force of the wall. As for the width of the crack in the house, the maximum width should be 1 mm.

For the masonry structure, the floor and the masonry are mutually constrained, and in the case of constraints, if the external temperature changes, the temperature deformation between the floor and the masonry is not coordinated, and the masonry will produce temperature stress. Depending on the location, some may be cracks in the wall skin caused by temperature changes, and some may be cracks caused by construction process problems.

There are two main steps: First, when you find a crack in your house, you should ask a professional department to identify it. Secondly, according to the results of the appraisal, find out your right to make a claim, whether to ask for repair or check out.

The structure of the house will be deformed due to the change of the surrounding temperature, so the expansion coefficient of different materials is different, which will cause the formation of temperature cracks. If there are cracks in the brick-concrete structure of the house, the house may be a quality problem, and it should be dealt with in time.

The roof is not eradicated in place: for the old house when reinstalled, I believe everyone will do the original wall and roof eradication, but for the old house, the roof not only has a large white layer, the original roof is not in place, the screed layer of the roof is too thick, and the temperature of the roof is too high, so it must be timely and thorough when solving, only in this way can the safe use of the house be ensured. If the putty powder surface layer is too thick, it will crack and hollow.

Yes. Because the old houses are very old, those buildings are old, and if there are cracks, they can easily collapse. When you come across a house with a crack, try not to live in it anymore.

If there are cracks in the old house, it cannot be said that it has become a dangerous house, but it is dangerous, and if there is a large area of cracking, then it is a dangerous house.

This is indeed the case, indicating that the house has been damaged to a certain extent, so you should be vigilant and do not continue to live in it.

Be. Therefore, at this time, we must repair the house in time, we must pay attention to the value of our lives, and we must not compromise.

Cracks have a certain impact on the beauty and durability of the house, but there is no big impact on the overall structural safety of the house.

If the damage to the house is not high (grade C), then the appraisal center will give you repair advice, and if the damage is relatively high, the appraisal center will organize a more professional survey. For buildings that are severely damaged or dilapidated (Grade D), the appraisal center will recommend the evacuation of residents in a timely manner, and then make recommendations for reinforcement or reconstruction of dilapidated houses.

Generally speaking, the crack is transverse, which is caused by the drying of the wall, if it is an oblique crack, then it should be noted, it is likely to be caused by uneven foundation sinking.

It is more difficult to remedy, so it is necessary for the property management company to ask professional personnel to check it (experts will have to charge more), and make corresponding measures, such as adding columns, etc.

Hazardous Housing Identification Hazardous Housing (abbreviation"Dilapidated houses"It refers to the load-bearing components that are already dangerous components, the structure has lost its stability and bearing capacity, and may collapse at any time, and cannot ensure the safety of the house.

Dilapidated houses are divided into whole dilapidated buildings and partial dilapidated buildings: a whole dilapidated house refers to a house that may collapse at any time; b Locally dilapidated houses refer to buildings that may collapse at any time.

Dilapidated houses are identified in the building and square meters in the construction area are the unit of measurement.

a. The whole dilapidated building is counted in square meters of the floor area of the whole building; b Partially dilapidated buildings are counted in square metres of floor area of the collapsed part of the building.

The appraisal of dilapidated houses should be based on the hazard identification of foundation and structural components, combined with the historical state and development trend, comprehensive analysis and comprehensive judgment.

In judging the danger of foundation or structural components, it should be considered whether the hazards of the components are isolated or related. a Structural hazards do not constitute structural hazards if they are isolated; b If the hazards of the components are relevant, the hazard range should be determined in relation to the structure.

In terms of historical status and development trends, the following factors should be considered on the impact of the hazards posed by the foundation and structural components. a. The degree of structural ageing; b. Influence of the surrounding environment; c. The value of the design safety degree; d Structurally detrimental human factors; e Dangerous development trends.

Determination of the scope of danger The whole dangerous house The danger caused by the foundation and foundation may endanger the main structure and cause the entire house to collapse.

Hazards arising from walls, columns, beams, concrete slabs or frames that may constitute structural damage resulting in the collapse of an entire house.

Summary. If it is determined that it is a dilapidated house just because of a crack, this statement is a bit far-fetched, and each village has a corresponding village cadre, and each region is not the same, so if you want to apply for a dilapidated housing subsidy, you must contact the village cadres in advance to apply and explain the situation and the relevant person in charge to your home in time to investigate. If you meet the requirements, you can apply.

I'll send a few ** to see. Good.
