"Hidden project" one by one check What kind of "electrical installation" standard? Electrical line installations require high material quality and construction processes. Wiring materials are generally composed of wires, PVC pipe and wire accessories, and electrical switches. Since each material has many varieties and the quality varies, the prices vary greatly. As for the wires, the commonly used wire specifications are 1.5mm2, 2.5mm2, 4mm2, 6mm2, 10mm2, etc., and there are many varieties of each specification, such as BVT (double plastic protection), BV (single plastic protection), 2R-BW (flame-retardant double plastic), 2R-BV (flame-retardant single plastic), and the level is also different, there are international standards, national standards, and some are not up to standard, the price difference of 1-2 times, or even 3-4 times, Therefore, I hope that consumers do not covet small things and bring trouble to themselves. (Note: Some of the good materials on the market today include Qingfeng and Cheungang cards. The PVC line pipes include Baoshi, Alliance, and Huaneng Tongpai; etc. Switches are Panasonic, Matsumoto, etc.). Line pipe layout requirements: The lighting line and the outlet line should be controlled separately. The cable is 2.5mm2 BVV. The kitchen electricity, air conditioning electricity and jacuzzi must use the dedicated line. The cable is 4mm2 BVV. During the construction, the wiring lines must be up and down vertically, left and right straight, the wires must be covered with PVC pipe and fittings, and the shear wall or load-bearing wall that cannot be destroyed must be covered with anti-wax pipe insulation material. "Water repellent treatment" is generally used in kitchens and bathrooms to prevent water from seeping downstairs and walls. The current waterproof materials used by the regular decoration companies are Luban or Huili brand tar polyurethane waterproof coating rubber. The construction method is: firstly smooth the wall or the ground, clean the team, wait until it is dry, put the waterproof coating material in the A material and stir for 3-5 minutes, then paste the tiles and floor tiles. Please pay attention to the owners, some construction teams are now cutting corners in order to cut corners, replacing asphalt with waterproof materials, most owners do not understand the mystery, asphalt as long as 38 yuan / barrel (8.5 kg load), 4.47 yuan per kg, each kg can be painted 2 square The area, that is, the cost per area of ​​the United States only costs more than 2 yuan for material, and it cannot achieve a good waterproof effect at all. The waterproof coating is quite different. Compared with Luban waterproof, each group has 330 yuan (16kg/group) and 20.63 yuan per kg. It is used according to the instruction manual. The dosage per square meter is about 2.5kg, that is, 51.58 yuan/sq. Meter, can absolutely achieve the waterproof effect from the performance, but the material cost is 49.34 Yuan more than the asphalt per square meter. Therefore, the general formal decoration company uses waterproof coating, the purpose is to ensure the quality of the project, on the one hand is responsible for the owners, on the other hand is to protect the consumer's own credibility. Because, generally, the formal decoration company has a one-year warranty promise when signing the renovation contract. If the waterproofing is not done with a hard material, the decoration company will be responsible for the consequences. In order to pursue greater profits, the “guerrillas†cut corners and materials, and used one shot to change places. If owners have problems with maintenance, they may not even find them, but only eat them. Therefore, to remind the decoration of the consumer room, the selection of the decoration company must be cautious; and carefully identify the asphalt and other waterproof coatings.

Today's routine construction is to bury water pipes in walls. Water installation is divided into water supply installation and drainage installation. The task of the water supply system is to ensure water quality, water quantity and water pressure. The principle of water supply pipelines is to shorten the pipeline layout while ensuring the safety and convenience of water supply, and to facilitate construction, maintenance and aesthetics. The current water supply pipes used by some of the regular decoration companies are mostly compound copper pipes or Nikko tubes that meet the standards. Because these materials are of good quality, they are also more expensive, but this is less than some of the non-compliance used by the “guerrillasâ€. Composite pipe or galvanized pipe is safe and practical. After the last water supply pipe is installed, it must be decompressed for 2-3 hours with the test press to seal the pipe. Drainage pipes are used to remove sewage from people's daily lives. Drainage installation should be connected to the exit in the shortest distance. If the pipeline is long, the slope should be large, and the drainage material must meet international standards. Nowadays, the materials on the market include Baoshi, Liansu, and Huanengtong. tube.
With the increase of household appliances, people's demand for electricity is getting higher and higher, so the electrical wiring project must be carefully designed by the electrical engineer to create a circuit diagram before construction, so that the owners in the lives of convenient and safe.
