Hydropower renovation is the first step in the renovation. Because it is a hidden decoration, many people may fool past, but the hydropower renovation is actually very important, even more important than some obvious external decoration. In the same way, water and electricity decoration is also a tedious thing. The materials it needs are more tedious. If the owners do not pay attention to it, or if the plans are cheap, they have chosen some materials with poor materials. It will be too late to regret it! So, what materials are needed for hydropower fittings? This article clearly lists all the building materials that need to be used in the hydropower reform, as well as a reference to some usage.
| First, look at the steps |
Want to know what building materials need hydropower reform, let's take a look at what projects of hydropower reform!
1. Slotting: The construction method is to first play the line and then slot. Slotting of pipelines must be parallel lines and vertical lines according to requirements (better if there is a comparison of construction plans for hydropower projects). Pipes that are to be routed in parallel must be controlled at a height of 60-90 centimeters (counting from the ground). Pipes with faucets must be vertical.
2. Installation: The pipeline is divided into cold water pipes and hot water pipes. Hidden pipes eliminate the use of galvanized iron pipes. First of all, through the construction plan construction personnel and the owner to discuss the location and use of water functions. Arrange the water master to drain and install all taps and water positions. If there is a construction drawing, it can be arranged according to the construction drawing. If there is no complete drawing, the owner can communicate with the owner to increase the location of the water use function.
3. Inspection: Water pipeline inspection is very important, and it is related to future water safety hidden troubles. We usually use pressure testing to do pipeline inspections. Pressure test is one of the ways to check leaks in pipelines. First, all the inner wires are staked to death with a gambling head. Use pressure gauges (home improvement 6-8 kg) to test water. Check all pipe fittings after pressure. The second method is to open the floodgates for two days and two nights, and check all joints on the third day. Take the former method normally.
4. Waterproofing: After the installation of the waterway pipeline, seal all the trunks of the bathroom with cement sand (the floor of the bathroom and the kitchen should not be grooved). After the trunking and the ground are dry, clean the floor and the wall again. The water on the wall surface can be used for waterproofing. The wall waterproofing is best done for more than 80cm. If there is a furniture wall on the back of the kitchen wall, it must be full of walls. Plays a damp-proof role for furniture. The first time to enter the venue to do waterproofing is to be able to determine that the ground will not leak. After the pipeline is installed, the wall and floor will be re-doed once again to make the floor and wall more effective in waterproof protection. In the acceptance of hydropower projects, it must be tested whether the waterproof is qualified.
5, circuit slot: After consulting with the owner to use the power function and requirements, with the master electrician, play well parallel and vertical line slot. Place the switch socket box. The socket type is slotted 40 cm from the ground, the hanging air conditioning socket is slotted 2.2 meters from the ground, and the switch is slotted from the ground 1.2-1.4 meters. The bottom of the switch socket is installed and the horizontal line is to be slotted. The kitchen and bathroom rooms must be slotted according to the designed function. Coincidence must have a lock.
6, circuit wiring: normal home 2.5-6 square meters above the copper core, 16mm above the line tube. Strong and weak wires and ducts should be separated.
The requirements for strong and weak power cables are 30 cm apart at the bottom of the limit, and the air-conditioning sockets are dedicated to groups of wires of more than 6 square meters, electrical sockets are dedicated to 4 square meters, and switches are grouped with more than 2.5 square meters. The air conditioning line group is more than 2 meters away from the ground. The ground wire of the electric wire group, the switch and the top line of the wall of the lamp line group. The bottom of the switch socket must be installed horizontally and vertically so that the rear panel installation will be evener.
