In home decoration, water and electricity installation can be regarded as a concealed project, so the quality of water and electricity installation not only affects economic losses, but also may cause certain harm to personal safety. Therefore, the standard size of water and electricity installation cannot be ignored

in home decoration, water and electricity installation can be regarded as a concealed project, so the quality of water and electricity installation not only affects economic losses, but also may cause certain harm to personal safety, so the standard size of water and electricity installation cannot be ignored. Therefore, next, I will introduce the standard dimensions of hydropower installation and the standard specifications of hydropower installation

standard size of water and electricity installation

1. Basin: 50cm shower: 120cm toilet: 20cm vegetable basin: 40cm mop pool: 75cm washing machine: 120cm electric water heater: 170cm gas water heater: 130cm bathtub: 35cm mixing valve between cold and hot water: 15cm

2. Common dimensions of kitchen equipment: the height of kitchen cabinet console is 810-850mm; The front and rear depth is 500mm-600mm, and the height from the operating table to the bottom of the hanging cabinet is about 550mm. It is not good to be too high or too low; The shower outlet of the hanging cabinet is 1100mm from the ground

3. The exterior line of satellite TV is placed with the bedroom facing the south window. The commonly used ones are live broadcasts (entertainment, Mandarin) for Taiwanese Chinese in the southwest, and all English programs such as CNN, BBC, HBO in the southeast. Place the program in a specific location according to your personal preferences

4. The height of the inserted seat is relatively consistent with that of the original inserted seat, generally 300-350mm

5. The double control switch is 850mm from the ground

6. The wall mounted TV power supply is 1100-1300mm above the ground, and the height is about 700. It is difficult to place objects too high, and the thickness is 300-350mm. The height of the range hood is a standard height from the stove surface to above. In case of special circumstances, the distance of the bottom can be appropriately changed to 750mm

water and electricity installation standard specification

1. Wiring principle: horizontal and vertical Special Zhongcai PVC flame-retardant conduit shall be used. The conduit must be fixed in the trunking. When the junction box is connected with the conduit, the lock nut shall be used. A pipe clamp shall be used every 80 cm for the straight pipe and every 20 cm at the corner

2. The socket is on the upper part of the wall. It is vertically slotted upward on the wall and within the installation line of the decorative corner line installed on the top of the wall. If it is on the lower part of the wall, it is vertically slotted downward to the bottom of the installation skirting board. The slotting depth should be the same. After the control line is popped on the wall and the top straight, it should be cut on the wall with a cutting machine and slotted with a machine

3. Use Zhongcai PVC pipe, use spring to bend when bending, and do not use 90 degree elbow and tee (at this point, we basically do not have this kind of situation at present). When installing the line, we must add protective wire sleeve, use glue to connect, and the sleeve edge should be closely connected Straight Smooth At the right angle corner, the inner side of the corner should be cut, and one side of the cut should be rounded off the arc interface, and then bent for installation

4. The pipe knuckle depth is moderate, and there is no burr. The pipe joint shall be wrapped with raw material tape for 5-6 turns, and the number of pipe twisted teeth is 5-6 teeth until the joint is tightened, and rotten teeth are not allowed to be connected into the pipe

5. After the conductor is installed in the sleeve, the conductor fixing tool should be used. First fix it on the wall and inside the wall, and then plaster it for concealment

6. It is strictly forbidden to lay the wire pipe directly under the composite board. (we haven't done well on this point at present, and we will communicate with customers in the future. The composite floor must be grooved.) the wire pipe under the solid wood floor must be reinforced

7. It is strictly forbidden to lay wire pipes in the kitchen On the floor of the toilet, prevent water from penetrating into the conduit. (there should be no conduit on the floor of the toilet, and we must strengthen treatment on this point)

8. The wire passing through the conduit should not be greater than 40% of the hole area of the conduit, and the wires in the conduit should not have joints. Wires for different purposes should not be mixed in one conduit

9. A certain length must be reserved for the wire entering the junction box, with 10 ~ 15cm reserved, and 100cm reserved for the sound. It is easy to switch through the hose Installation and maintenance of sockets

10. The distance between the water installation pipe and the wall should be 1.5 cm, hot on the left and cold on the right, with a spacing of 15 cm

11. The parallel distance between wires and water pipes should not be less than 30 cm, crossing The bridge crossing distance shall not be less than 10 cm

12. There must be no joints between wire points, and the hidden wires in the ceiling must be protected by flame-retardant pipes

13. After the acceptance of water and electricity, the trunking can be powdered and leveled. The wall slot should be filled with 1:3 cement mortar (the wall surface should be powdered and leveled twice)

editor's summary: This is the introduction of the standard dimensions of water and electricity installation and the standard specifications of water and electricity installation, hoping to be helpful to you. If you want to know more, you can pay attention to information
