With the popularity of home renovation in the capital, many families have re-decorated their homes. However, while enjoying the magnificent decoration, there have also been many problems. Among these decoration quality issues, due to the “hidden projectâ€, it has been accounted for a lot.
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 normative. In recent years, due to the designer's poor understanding of structural safety and fire safety in the design and construction of home improvement projects, many problems have occurred:
1. Due to the collapse of the entire or part of the ceiling, the ceiling becomes a "top drop." This is mainly due to the ceiling and floor, and the keel and veneer combination is not good, or caused by excessive load. 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. A chandelier or ceiling fan weighing more than 3 kilograms cannot be hung on the ceiling keel. Instead, a hook should be provided. If the ceiling uses gypsum board as veneer, its thickness should be about 9 mm.
2. Insufficient fixing of the balcony package resulted in slumping. 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. Therefore, when the balcony is packaged, the doors and windows must be horizontally and vertically aligned with the same height and appearance without distortion, open welding, and fracture. 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. The buried route is not closed. 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 zero right fire, grounding in 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 was not cleaned before painting, causing the paint to peel off and fall 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, and it should not be peeled, chalked or cracked.
These aspects are just a few aspects of the most likely problems in home decoration. Other "hidden projects" are also very important. You may wish to go to the construction site during the renovation process to “spot check†several times and solve the problem immediately.

Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
