What are the water and electricity standards for home decoration and home improvement water and elec

1. The material process must meet the requirements of the company's specifications: all wires are made of famous brands such as pigeon brand BV wires, lighting circuit sockets air conditioners 4mm2, kitchens, bathrooms 4mm2, and grounding wires, especially emphasizing that DAEX general light (16) pipes or DAEX (16) B pipes, round tees, direct, locks, and yellow wax pipes should be used in the threading, and bellows, elbows, and equal diameter tees are never allowed. 1 16 pipes can only be used for one circuit, 20 can only be used for 6mm21 circuits and the circuit between the toilet bomb and the switch.

2. For circuit laying, bury the bottom box (except for the kitchen and bathroom) first, lock the lock, and do not allow the wire to be buried directly in the wall, and the wire in the wire pipe is not allowed to have joints. All wire joints must be in the box or in the transfer box, when pay-off, the turning place is treated with cold bending technology, and the curvature of the line pipe is suitable for the pipe wall not to be deformed; The wiring adopts the twisted type, and the grouping and color separation of each circuit are clear: red, yellow, and green are the color codes of the zero line, and the yellow-green color line is the grounding color code.

3. The lower mouth of the socket wire box is 350mm, the lower mouth of the switch wire box is 1250mm, the lower mouth of the window cabinet wire box is 650mm, the lower mouth of the TV wall is 450mm, and the plasma spare sleeve is added. The switch line in the same room generally goes down from the top, the socket line goes up from the ground, and the weak line goes up from the ground. If the ceiling is not suspended, the strong and weak electricity will go to the ground.

The position of the switch and socket should be kept on the same horizontal line, and there is no obvious deviation from the visual vision. Toilet switches and sockets should be made of waterproof panels. And there should be leakage protection measures.

The kitchen and bathroom circuits must be put on the ceiling. Wires and water pipes and gas pipes shall not be in the same groove.

4. Strong and weak wires are threaded separately, different slots, but the words are not allowed to cross, and the distance between the strong and weak electric bottom box is 150mm-200mm (the whole room is unified standard). The line pipe joint should be glued, and the edge of the trunking must be brushed. Strong current and weak current cannot be in the same bottom box (including 118 series), and the trunking and line pipe are in a clear direction, horizontal and vertical.

If the 86 line is more than two side by side, it should be kept neat, no deviation in vision, no wall, and there is a lock connection between the box and the box, and the distance is 10mm

5. Before opening the box, the wire head must be wrapped to avoid electric shock. The ground laying pipe should be used for cement mortar slope protection, and the wall and top line pipe should be fixed with line cards. After the wiring is completed, it must be tested with a megohmmeter.

6. The construction personnel use electricity temporarily on site, and the wires cannot fall on the ground, can not fall on the ground, and cannot have spider webs, so safety must be ensured.

7. Lamps and sanitary ware are installed firmly, tightly connected, no loosening, no leakage.

One of the most important links in home decoration is water and electricity, after all, it is hidden in the wall, and if there is a problem in the later stage, it will be very troublesome. And what are the standards for pretending to be hydropower construction, and what are the steps of hydropower construction, do you know about it? Now let's take a look.

1. Home improvement water and electricity construction standards.

1. Locate the hydropower according to the design drawings of Youtong, and draw it on the wall with elastic lines; 2. Hydropower slotting is based on the standard of going to the top and not to the ground, and to go vertical and not horizontal; 3. The bottom box needs to be fixed with cement mortar in the front part of the trunking and maintain balance with the wall; 4. Separate pipes need to be routed between strong and weak currents, and tin foil should be used at the intersection of strong and weak currents.

Second, what are the steps of hydropower construction.

1. Punching and slotting.

This step needs to be closely linked to the design drawings to determine the location of the socket, the position of the slotted position, and the positioning of the cartridge on the wall by means of elastic wire. In the meantime, the slotting needs to use a cutting machine, and keep it flat and vertical, and the pipe should be about 8mm away from the wall.

2. Circuit. When connecting the lines between the various wire boxes, or between the wire boxes and the wire pipes, it is best to use the method of cup sparse connection. In addition, in the same room, all switches and sockets need to be kept within a certain height and there can be no error greater than 5mm.

3. Cleaning and protection.

When protecting the construction site, it is necessary to pay attention to the placement and protection of various materials on the site, and they should not be exposed to the sun, and the construction tools need to be placed in the same place. In addition, every time the construction is completed, it is necessary to ensure the cleanliness of the construction site.

4. Waterways. When designing the indoor waterway, it is necessary to ensure that the cold water pipe is on the right and the hot water pipe is on the left, and that the silver grinding pants are on the same level. If you want to go through a wall or a beam, make sure to walk through a hole as much as possible.

The distance between the two pipes should be around 30mm.

What are the standards for home improvement hydropower construction, and what are the steps of hydropower construction, I will introduce it here, do you understand? Home improvement water and electricity is a link that cannot be mistaken, and it needs to be carried out according to the standard to avoid unnecessary trouble in the later stage.

1. The parallel distance between the strong and weak wire pipes must be separated by more than 30 cm, and the line pipes cross without interference, and the strong and weak electric dark boxes can be close to each other, but the same box is not allowed. The trunking should be horizontal and vertical (except for the ceiling).

3. There shall be no joints in the wire pipe, and after the completion of water and electricity, the exposed wires of switches and sockets must be wrapped with insulating tape to avoid the risk of electric shock.

4. When installing the power socket, it should be left zero and right phase (fire), and the upper part should be the ground wire. The live line Hengqin enters the switch, and the zero line enters the lamp head.

5. The socket panels such as power supply and TV in the same room should be at the same horizontal elevation, and the height difference should be less than 5mm.

6. The toilet socket should be splash-proof. The power socket is generally 300mm from the ground, and the switch is generally 1400mm from the ground.

7. The lighting wire is, the socket is the air conditioner hang-up wire, the grounding wire is 4bV. Air conditioners and high-power electrical appliances should go all the way alone.

8. The gas pipe (pipe) must be open and cannot be sealed, and the gas company must operate if the pipe needs to be moved. Electric pipes, hot water pipes, and gas pipes should be kept at a certain distance from each other and should not be close to each other.

9. The hot and cold water pipe should be hot on the left and cold on the right, the hot melt connection PPR water inlet pipe can go to the ground, and the wire connection water inlet pipe must go to the top surface.

10. After the pressure test (pressure test, the pressure drop in half an hour is not greater, and there should be no water seepage and water leakage in pipelines, valves and joints.
