A, water and electricity installation size standard
1, basin: 50cm shower: 120cm toilet: 120cm electric water heater: 170cm gas water heater: 20cm vegetable basin: 40cm mop basin: 75cm washing machine: 130cm bathtub: 35cm cold. Common dimensions of kitchen equipment: the height of kitchen cabinet console is 810-850 mm; The front-back depth is 500mm-600mm from the operating table to the bottom of the cabinet. The height is about 550mm, neither too high nor too low is good. The shower outlet of the hanging cabinet is 1 100mm from the ground.
2. Outside the satellite TV, a south-facing window is placed, which is often used to broadcast live programs (entertainment, Mandarin) to Chinese in Taiwan Province Province in the southwest, and all English programs such as CNN, HBO and BBC in the southeast. Place the program in a specific location according to personal preference. The height of the socket position is relatively consistent with the original socket position, generally 300-350 mm
3. The double control switch is 850mm from the ground. The height of the wall-mounted TV power supply from the ground is about 700 mm (11300 mm), and it is laborious to place items too high, with a thickness of 300-350 mm The height of the range hood is the standard height above the kitchen countertop. In case of special circumstances, the distance from the bottom of the machine can be appropriately changed to 750 mm
Second, the hydropower installation standard specification
1, using Cai Zhong PVC pipe, bending with spring, not using 90-degree elbow and tee (at this point, we basically have no such situation at present). When installing lines, be sure to add protective line sleeves and connect them with glue, and the edges of the sleeves should be closely attached. In a smooth, straight and right-angled corner, the inside of the corner should be cut off, and the cut side should be cut into an arc joint, and then bent and installed.
2. Wiring principles: horizontal and vertical. Use special Cai Zhong PVC flame retardant conduit, which must be fixed in the conduit. When the conduit is connected with the conduit, lock nuts shall be used, and a pipe clamp shall be used every 80 cm for straight pipes and every 20 cm for corners.
3. The socket is on the upper part of the wall, and the wall is vertically slotted upward to install decorative corner lines at the top of the wall. If it is in the lower part of the wall, the socket should be slotted vertically downward to the bottom of the skirting board, and the depth of the slot should be consistent. Groove line and top straight should pop up the wall behind the control line, then cut the wall with a cutting machine and slot with a machine.
4. Pipe thread depth is moderate, without burr. Wrap the joint of the pipeline with raw material tape for 5 -6 times, and the number of winding teeth of the pipeline is 5-6, until the joint is tightened, and rotten teeth are not allowed to be inserted into the pipe. After the wire is put into the casing, it should be fixed on the wall and wall with wire fixing tools, and then plastered for concealment.
5. It is forbidden to directly lay the conduit under the composite board, especially the floor must be slotted, and the conduit under the solid wood floor must be reinforced. It is forbidden to lay the catheter on the kitchen and bathroom floor to prevent water from infiltrating into the catheter.
6. The wires passing through the conduit shall not be greater than 40% of the hole area of the conduit, and the wires in the conduit shall not have joints. It is forbidden to mix wires with different purposes in one conduit. When the conductor enters the box, it must be guaranteed to have a certain length, which is 10 ~ 15 cm, and the audio frequency is 100 cm. It is also convenient to put on a hose and install a switch socket.
7. The distance between the water pipe and the wall should be 1.5cm, and the distance should be 15cm. The parallel distance between wires and water pipes should not be less than 30 cm, and the crossing distance should not be less than 10 cm. There can be no joints between wires, and the hidden wires in the ceiling must be protected by flame retardant pipes. After the water and electricity are accepted, the trunking can be leveled, and the wall slot is filled with 1: 3 cement mortar (the wall is leveled twice).
The size standard of water and electricity installation is as above, and the plumber can do it for the owner. The owner only needs to know the standards and specifications of hydropower installation, and then see if the plumber has done a good job in accordance with the relevant standards when the project is accepted.
