Will cracks in the walls affect the overall structure of the house?

Will cracks in the walls affect the overall structure of the house?There are six situations when cracks appear in the walls of the house: 1. If it is a frame structure.

The shrinkage value of the concrete of the infill wall and the beam, plate and column is inconsistent, resulting in the shrinkage crack between the lower mouth of the beam and the wall. 2. If the house is newly built, there will be a settlement stability period in the house, and at this time, it is easy to produce horizontal and oblique cracks on the wall due to uneven settlement. 3. Due to the later stage of construction, the walls on both sides of the lower part of the window sill and the filling part of the construction opening are not constructed according to the requirements of the quality specifications, resulting in oblique cracks at both ends of the window sill and shrinkage cracks at the construction opening.

4. Shrinkage cracks at the splicing joints of the insulation board. 5 After the trunking is filled, due to the cement mortar.

The drying speed, shrinkage rate and putty powder.

Cracks 6 can also occur if the wall putty is scraped too thick at one time, or if the thickness of the entire wall is too different. The formation of the above-mentioned cracks: some are caused by the characteristics of building materials, some are caused by construction technology, and some are caused by settlement.

But basically it will not cause the overall structural safety of the house. However, due to the large amount of settlement, cracks that exceed the design limit value should be paid close attention to. This problem rarely arises, and within half a year of the completion of the project, the settlement observation of the house is still ongoing.

In short, the deviation value is allowed in the national standard.

Cracks in the range are not treated.

If there are cracks in the non-load-bearing wall, it will not affect the overall structure of the house, and if there are cracks in the load-bearing wall, you should be careful.

There are many kinds of cracks, and one is a structural crack, which should be paid attention to.

It's a quality issue.

Look for cracks on the ground and roof of the house, no cracks are the best, if there are cracks, to see what kind of cracks. Generally speaking, cracks parallel to the beams of the room are quality problems, but they are basically not dangerous and will not hinder the use of the cracks after repair. If the crack is at a 45-degree angle to the corner of the wall or perpendicular to the beam, it means that the house has serious settlement and structural quality problems.

Whether there are cracks in the external walls of the house, if there are cracks, it is also a serious quality problem. Look at whether there are cracks in the load-bearing wall, if the cracks run through the entire wall and penetrate the back, it means that there are hidden dangers in the house. If the crack is at a 45-degree angle to the corner of the wall or perpendicular to the beam, it means that the house has serious settlement and structural quality problems.

Whether there are cracks in the external walls of the house, if there are cracks, it is also a serious quality problem. Look at whether there are cracks in the load-bearing wall, if the cracks run through the entire wall and penetrate the back, it means that there are hidden dangers in the house. Yes, the quality problem is certain, the question is how serious the quality problem is, and whether it affects the safety of the house.

After our house is scattered or lived for a long time, there will be a lot of problems, especially the problem of the wall, so I will talk about itCracks appear in the walls of the housereasons andCracks appear in the walls of the houseworkaround.

1. Cracking of the paint layer.

If the wall temperature is too low or too high, the film on the wall surface will not work properly and the film on the wall paint will crack. Cracks can also occur if the quality of the wall paint is not correct or the structure is not reasonable. However, this is less common and the crack can be sanded with fine sandpaper until it is smooth.

Flatten with wall paint of the same color and then repaint.

2. Cracking of the putty layer.

If there is a crack in the adhesive layer of the wall structure, it can also create a crack in the wall paint, creating the visual perception of the crack on the surface of the wall. This type of crack problem in the putty layer can be selected with some knives and so on. The tool will enlarge the crack so that it can be better filled with a little caulking plaster.

After refilling, the sand and sand then brush off the paint off the wall.

3. Cracks in the plastering layer.

Cracks appear in the walls of the houseThe wall itself is good, the cracked surface of the wall is cracked. It can be caused by cracks in the walls and plaster layers. It is caused by the shrinkage of the cement mortar during the drying process, which leads to the possibility that cracks may appear in the plastering layer, or they may be caused by insufficient materials used in the coating or inadequate construction techniques.

1. Appearance repair method.

If the crack is small, it will not have a significant effect on the decorative effect of the living room and will not affect the structure and stability of the wall. So, we just need to solve it in a simple way. Usually, a layer of cement slurry is applied to the cracked surface, or the concrete surface is painted with anti-corrosion materials such as paint, which can play a role in repairing and preventing continuous cracking of the concrete.

2. Grouting and embedded plugging method.

If the crack is large and deep, seriously affecting the aesthetics of the living room or the phenomenon of the wall, it must be repaired by grouting. The grouting method uses a pressure device to press glue directly into the cracks in the concrete, and once the rubber hardens, it can mix with the concrete into the body, thus blocking reinforcement.

Legal analysis: cracking depends on the size and location of the crack, if the surface cracking is generally due to the moisture when painting the wall, in the rush to do the surface layer after not waiting for drying, after experiencing thermal expansion and contraction of the layer cracking, this situation generally does not affect the quality of the house and living. If it is a crack in the deep structural layer of the wall, it is a structural problem, it is recommended to ask a special person to come to investigate, if it has been reinforced by professionals, or there is a problem, it is not recommended to live.

Legal basis: Interpretation of the Supreme People's Court of the People's Republic of China on Several Issues Concerning the Application of Law in the Trial of Cases Involving Disputes over Contracts for the Sale and Purchase of Commercial Housing Article 13 If the buyer's request to terminate the contract and compensate for losses is seriously affected by the quality of the house, it shall be supported. If there is a quality problem in the house delivered for use, the seller shall bear the responsibility for repairing it during the warranty period; If the seller refuses to make repairs or delays the repairs within a reasonable period of time, the buyer may make repairs on its own or by entrusting others to do so.

The seller shall bear the cost of repair and other losses caused during the repair period.

There are the following problems that cause cracks in the walls of houses:

1.Cracks in the walls of houses caused by uneven foundations: After the house is built, the foundation will generally sink.

2.If the settlement of the foundation is uneven, the relative displacement of the part with the large settlement and the part with the small settlement occurs, and the shear force and tensile force are generated in the wall, and when this additional internal force exceeds the tensile and shear strength of the wall itself, cracks will be generated, and these wall cracks will increase with the increase of the uneven settlement of the foundation.

3.There are errors in the structural design, cracks caused by unreasonable structures due to omissions in the calculation of loads, and unreasonable structures.

4.The construction quality of masonry is poor, the ash is not full when the wall is built, the thickness is uneven, the assembly method does not meet the requirements, etc., when the masonry brick wall is built, the bricks are not wet, and the dry bricks are used on the wall, etc., will reduce the bearing capacity of the masonry, so that the wall will have cracks in the future.

5.After the house is completed, various pipelines are buried through the wall, which destroys the integrity of the wall, reduces the bearing area of the wall, weakens the bearing capacity of the wall, and causes cracks in the wall.

6.If the house is under warranty, it should be warranted by the construction unit, and you can contact the developer to repair the cracks. If the developer refuses to take responsibility for the warranty, you can file a complaint with the local building and construction authority or with the consumer association.

At the same time, Article 53 of the "Regulations on the Quality Management of Construction Projects" clearly stipulates that any unit or individual has the right to report, accuse and complain about the quality accidents and quality defects of construction projects. Therefore, in the event that the negotiation fails, consumers can protect their legitimate rights and interests through legal means.

7.In short, the severity of the temperature difference crack is related to the indoor and outdoor temperature. Construction quality, expansion joint spacing, roof insulation, window size, wall thickness, etc.

Cracks in the exterior wall of a house can be large or small, so what are the situations? PChouse will explain it to you. 1. Temperature cracks.

This situation is more common, although this kind of crack affects the appearance, but will not produce potential safety hazards, so when repairing, you can paste non-woven fabric, paste PVC mesh cloth or plug the crack with mortar, and then repair it with paint.

2. Settlement cracks.

This kind of crack generally occurs in new houses, because the foundation of new houses will gradually stabilize within 2-5 years, and if cracks occur during this time, cement mortar, polymer mortar caulking or elastic putty, gypsum filling and pasting can be used.

3. Structural cracks.

This kind of crack is more serious and will affect the safety of the structure, so it is necessary to ask professionals to take corresponding measures according to the crack situation.

4. Cracks in latex paint on the surface.

If there are cracks on the surface of the latex paint, you should first use fine sandpaper to sand the cracks off, and then reapply the latex paint. If the seam is cracked, it should be moistened with warm water and re-painted with wallpaper glue.

5. Putty screed cracks.

If the crack has penetrated deep into the putty layer, you can first use a tool to expand the crack to the size of the cone, fill in the caulking plaster and polish and level, then paste the mesh cloth or kraft paper and then use putty to level it, and finally paint or paste wallpaper.

6. Cracks in the plastering layer of cement mortar.

If there is a large area of hollowing in the plastering layer, it is necessary to knock off the plastering layer first, redo the cement mortar plastering, and then paint or paste wallpaper according to the normal process. However, this kind of repair is relatively high, and the owner can choose the repair method according to his own economic ability.
