How is there many cracks in the house in the city square of Changsha County?

1. Cracks caused by different temperature differences, such as splayed cracks and horizontal cracks, are mainly caused by different temperature differences, because many houses are now built by combining reinforced concrete and brick walls, and their respective expansion coefficients are different, resulting in different tensile stresses under the same temperature change, which is generally not the case when setting expansion joints during construction.

2. Cracks caused by uneven settlement. In the process of long-term use, if the foundation is not uniform or the bottom structure is unstable, certain settlement will occur under the downward force of the house. The uneven settlement in different areas will destroy the rigidity of the house and produce problems such as ground, level and inclined cracks.

3. Cracks caused by insufficient bearing capacity of brick masonry. The load force of brick-concrete structure is not very strong, so this structure can not be used in high-rise buildings. In buildings with high floors, cracks are easy to occur in the weak parts of brick masonry walls under excessive load.

4. Cracks caused by decoration materials, decoration materials will also produce wall cracks in the case of improper construction, but such cracks generally exist on the wall and are also caused by cold and hot deformation caused by temperature difference, and such cracks generally have no safety impact.

5, cracks caused by comprehensive reasons, cracks in the wall are sometimes not only caused by a certain factor, but also may be several problems. If you want to remedy this time, you must check the problems one by one and implement remedial measures according to the situation. Of course, the most important thing is that the house should be well constructed in the early stage of construction in order to better avoid cracks.
