What are the standards and requirements for water and electricity decoration, and what are the const

1. Technical regulations and technical regulations for waterway construction:

1. The spacing between hot and cold pipes.

Do not put hot and cold water in the same sink to avoid blisters.

2. The height of the drainage pipe.

The diameter of the pipe is 2 cm, the hot water pipe is 1 cm, and the cold water pipe is 1 cm.

Second, the line construction regulations:

1.When wiring the wire, pay attention to the color separation, blue is the zero point, red is red, and the ground wire is yellow.

2.Universal sockets square millimeters; 4 mm² kitchen and cupboards; The illumination area is millimeters squared.

3. Strength and weakness stage.

The interval between strong and weak current should be more than 30 cm, and strong current lines such as lighting and sockets should not be kept at a distance of 30 cm from weak current lines such as network cables, ** lines, ** lines, etc., to prevent signal interference.

4. The pipe is connected with a casing, the junction between the pipe and the pipe is in the middle of the pipe, and the lower part of the pipe is fixed with a sleeve or clip with PVC adhesive.

5. It is not possible to wire in wet areas (bathroom, kitchen, balcony), and when laying PVC cables in brick houses, the distance between the wires and the wall must be 5 mm.

6. It is strictly forbidden to share strong and weak lines, and the intersection or special treatment of strong and weak lines (such as Wuxi strong and weak lines), and whether there is color in strong and weak lines.

7. When the mass of the chandelier exceeds 3 kg, it should be placed at the upper end of the chandelier, and the bulb should be connected with the buried part, but not directly connected with the wooden wedge and wooden brick.

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.
