About cracks

There is a horizontal crack in the skin brick under the beam, which is caused by the subsidence deformation of the back wall pressing on the floor, and it can be scraped again; There are cracks in the external wall of frame structure, vertical cracks, uneven distribution, which are caused by the cracking of post-built walls and columns. If there is no tie between the wall and the column, it will be in trouble. If there is a brace, wipe it again and press it into the crack-proof net. There are radial cracks in the shear wall, which should be a plastering problem and not resistant to things; There are splayed cracks in the eaves, which are temperature cracks and may leak rain. If rework, pay attention to wall reinforcement; The cracks in the top plate of frame structure vary in length, and most of them are concentrated at the joint between plate and wall, not at the joint between plate and beam. This is a very serious problem, that is, the fastener is missing or crushed and cannot be repaired; There are cracks parallel to the beam, which is hard to say.
