>> Interpretation of hidden construction site The so-called "hidden project" is a construction project that has been concealed after renovation and cannot be seen on the surface. According to the renovation process, these "hidden projects" will be covered by the next 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 poor design and safety of designers in the design and construction of home decoration projects, many quality problems have occurred. Below we will introduce you to some of the major aspects and ways of prevention: 1, due to the collapse of the roof as a whole or in part, so that the ceiling becomes "falling." This is mainly due to the bad combination of the ceiling and the floor slab and keel and veneer, or the excessive weight bearing. According to the regulations, the ceiling keel shall not be twisted or deformed. The installed keel shall be firm and reliable. The horizontal deviation shall not exceed 5 mm. Any pendant or ceiling fan exceeding 3 kg in weight shall not be hung on the keel of the ceiling, but shall be separately provided. If the ceiling is made of gypsum board, the thickness should be about 9mm. 2, the balcony package is not fixed due to slump. Due to the current housing design, there is no “settling point†for the packaging material on the balcony, which makes it difficult for the balcony to be packaged. When packaging the balconies, the doors and windows must be horizontally and vertically aligned with the same height and appearance. There should be no distortion, open welding, or fracture in the appearance. The gap between the frame and the wall should be full and dense. 3, pipe leakage caused damage to the roof. In addition to the upper and lower water pipes in the kitchen and toilet in the family room, the heating pipes in each room are actually more prone to problems. Because the installation of pipelines is not easy to check, after all the pipeline construction is completed, it must be checked by water injection and pressure, and no run, run, drip, or leak will be considered. 4, buried burial line hidden danger. Due to the fact that many residences currently use buried burial lines, it is not easy for the head of household to check the construction quality. According to regulations, buried lines cannot be buried directly in the plastering layer but must be sheathed outside the wires. Wires in the bushing must not be twisted or jointed. In addition, when installing the line, we must strictly abide by the "fire line into the switch, the zero line into the lamp left and right fire, grounding on the" provisions. After the completion of the construction, in addition to the power inspection, the construction team will also provide the owner with a detailed circuit configuration plan. 5, the substrate is not clean before painting, resulting in paint peeling off. Before painting the walls, be sure to remove the original wall coverings and not leave oil. The putty on the wall should be dense and firm with the wall, without peeling, without chalking, and without cracks.
