Anonymous users2024-01-24The failure of ordinary concrete cast-in-situ structures is processed, and the obvious speed of development of cracks can be seen, which is a sign, which tells you that danger is about to occur, rather than collapsing instantly. Only prestressed concrete elements are damaged instantaneously.
The main causes of cracks in the floor slab are:
1) uneven settlement of buildings;
2) temperature shrinkage cracks;
3) Caused by materials or construction and design reasons.
Is it a crack close to the root of the wall parallel to the wall? If so, it is because the board is against the wall and forgets to match the negative reinforcement (that is, the reinforcement on the top of the board, which is also called gluten). >>>More
Pro: This is the reason why the floor slab is too thin, that is to say, your house belongs to the tofu slag project, the cement used in the project is unqualified, and the steel bars in the floor slab are also missing two pounds.
The key depends on the structure of the balcony slab and the nature of the cracks.
The possibility of retaining construction joints during the construction process is greater, and the slight cracks caused by improper treatment of the construction joints during the construction process may also be caused by inadequate maintenance. If the crack is not large, it will have no effect on the structure.
Whether it is on-site repair or return to the factory for repair, there is basically no guarantee that it will not crack in the future, which is the characteristic of the wood will shrink or bulge.
