[Introduction] With the popularity of home decoration, there are more and more renovation problems. Among these quality problems, the “concealed project†is a large proportion. The so-called "concealed project" is a construction project that is concealed after renovation and cannot be seen on the surface. According to the decoration process, these “concealed works†will be covered by the latter process, so it is difficult to check whether the materials meet the specifications and whether the construction is standardized. In recent years, due to the design and construction of home decoration projects, designers have not considered the structural safety and fire prevention, and many quality problems have occurred. Below we will introduce you to the main aspects and the prevention methods: 1. The ceiling is turned into a “top†due to the overall or partial collapse of the ceiling. This is mainly because the ceiling and the slab and the keel and the veneer are not well integrated, or the load is too large. According to the regulations, the suspended keel shall not be twisted or deformed. The installed keel shall be firm and reliable. The horizontal deviation shall not exceed 5 mm. The chandelier or ceiling fan exceeding 3 kg shall not be hung on the ceiling keel, but a separate hook shall be provided. If the ceiling is made of plasterboard, the thickness should be around 9 mm. 2, the balcony package is not fixed enough to cause collapse. Due to the current design of the house, there is no “foothold†for the packaging material on the balcony, which makes the balcony package difficult. When enclosing the balcony, the doors and windows must be horizontal, vertical, high and low, and the appearance is free from deformation, open welding, and breakage. The gap between the frame and the wall should be full and compact. 3. The leakage of the pipe caused damage to the ceiling. In addition to the water and sewage pipes in the kitchen and bathroom, the heating pipes in each room are actually more prone to problems. Since the installation of the pipeline is not easy to inspect, after all the pipelines have been constructed, they must be inspected by water injection and pressure. If they are not run, run, dripped or leaked, they will pass through. 4. The buried line is buried in danger. Since many living rooms are currently buried in dark lines, it is not easy for the head of the household to check the quality of the construction. According to the regulations, the buried circuit can not be directly buried in the plaster layer, but the casing should be outside the wire. The wires in the bushing must not be twisted or jointed. In addition, when installing the line, it is necessary to strictly abide by the provisions of "Fire line into the switch, zero line into the lamp head left zero right fire, grounding on the". After the completion of the construction, in addition to the power-on inspection, the construction team should also provide the owner with a detailed circuit configuration diagram. 5. The substrate is not cleaned before painting, causing the coating to peel off and fall off. Before painting the wall, be sure to remove the original wall covering, not to leave oil. The putty coated on the wall should be dense, firm, non-pigmented, non-powdered and crack-free.
