Rough room water and electricity wiring skills, how to wiring is correct

Nowadays, most of the houses delivered by developers are rough houses. Many renovation companies have their own design ideas, including changing the water and electricity lines. Personally, it is recommended that the indoor space arrangement should be considered before decoration, as long as the water and electricity interfaces are reasonably convenient and sufficient.

It is not advisable to change. As long as it is a qualified developer, the important parts are still safe and reliable, and the design is in place. Changing the route at will can also be a safety hazard.

For home decoration, whether it is a new house decoration or an old house renovation, we generally have to transform the original water and electricity. Especially for some of the newly built commercial houses are rough houses, so do we have to carry out hydropower transformation? The following questions are used as an example to answer questions related to water and electricity transformation.

Why does the water and electricity of the rough house have to be renovated? Why should the water and electricity of the rough house be renovated depends mainly on the characteristics of the water and electricity layout of the rough house and the needs of our family use. Because each family's needs for water circuits are different, and the original layout of water and electricity cannot meet the needs of each family.

Therefore, there are three reasons why the rough house needs to be renovated with water and electricity.

: The water and electricity of the blank room only meet the simple use function. For example, the waterway in the rough house generally reserves a water point in the kitchen and bathroom, and a water point is obviously impossible to meet the needs of our use, so it needs to be renovated at this time.

The same is true for circuits in the home, where each room is basically reserved for a lamp, and then reserved for a few sockets, which is also difficult to meet the needs of use.

: Each of our households has completely different needs for water and electricity. For example, many families are now equipped with hot and cold water, and some families are equipped with circulating water, purified water, whole-house water purification, etc., so the waterway must be renovated.

In addition, the original circuit also needs to be remodeled to meet the needs of the use function of each room.

: The materials used in the water circuit in the blank room are relatively general. This is mainly reflected in the materials used in the circuits in the rough room.

For example, the quality of the switch and socket panels in the circuit is average, and it is generally necessary to replace it when it is renovated in water and electricity.

The waterway goes up and down the circuit, so that it is the most reasonable layout, does not interfere with each other, or is it particularly good to maintain in the future.

There is no water and no electricity in the rough house. Hydropower decoration work should be done better, what is the water and electricity decoration procedure of the rough house, the rough house needs hydraulic decoration, so it is necessary to be able to clarify the relevant decoration to ensure the smooth completion of the decoration. What are the precautions for blank, water and electricity decoration.

What are the precautions for the hydraulic decoration of the rough room in the stage of hydraulic decoration of the rough house. Rough house water and electricity decoration stage, pipe preparation trough. When the water pipe begins to be slotted, the construction plan is carried out according to the construction, and the line should first be elasticated according to the size.

Then you can make a groove and don't let the slotted line bend. The notch should go in both directions. One is parallel to the wall and the other is perpendicular to the ground.

The height of the parallel line is generally adjusted, and the control height is 60 to 90 cm above the ground. The place where the faucet is located must be vertical. The general notch depth is 4 cm.

Once the groove is opened, the dimensions are measured and the position determined. Water plumbing and installation. The next task is the water pipes and their installation.

At this time, it is necessary to decide on the good materials.

It is necessary to decide whether to use PPR pipes or aluminum-plastic pipes. The choice of plumbing depends on personal preference or the choice of the family. According to the construction drawings, the location of its water area, the function of use, the scope of use, etc., should be discussed with the owner.

In this case, all faucets should be fixed first, including burying them according to the location of all faucets and water, and the position of the grooves of the water pipes. Waterway pipeline inspection, after the waterway pipeline is fully installed, a preliminary inspection should be carried out. Inspections during this period are quite important.

Because if there is a leak, the rework will recover well. Pipeline testing requires a pressure test method. That is, all the inner wires are sealed with a casino, and then the water is tested with a pressure gauge to confirm whether there are any leaks in all the connections of the pipe.

Check whether there is any water infiltration in the joint after the plug comes up, whether there is any leakage in the buried water pipe two days after opening the gate, etc. The walls and floors are inspected for waterproofing. Once all the plumbing was installed, the nine-seater units for all the water pipes in the bathroom and kitchen were blocked.

When the sediment is dry, the floor and walls can be cleaned.

We must pay attention to the planning is very reasonable, and we must take into account many follow-up problems, and we should set up this thing after the later decoration layout is set up.

Be sure to plan in advance, be sure to measure the size in advance, be sure to avoid dangerous places in advance, and be sure to have a reasonable routing plan.

What needs to be paid attention to is the problem of the circuit, and it is necessary to avoid leakage, and it is also necessary to avoid short circuits, and safety issues should be considered, and these hydropower lines should also be darkened.

Home decoration wiring is a very important problem, there are many aspects that need wiring, the common is hydropower wiring, now there are network wiring and TV signal wires, etc., because many friends pay attention to beauty, so they choose concealed wiring, so wiring is the first step of decoration, the quality of wiring is very critical, reasonable wiring can make the use of the future more convenient and fast, the steps of wiring are more fine, it is recommended that you must plan the pattern of your house before wiring, Figure out where you want the wiring.

You need to pay attention to your decoration style, and you need to pay attention to the electrical equipment you also need to buy, so that you can choose the right wiring according to these things.

Routing can be done in a point-to-point manner, which can better save money and better check problems.

In the process of decorating the hall, the water and electricity wiring is very critical, some can be destroyed to walk the ground, and some need to walk the wall. It depends on the overall structure of your house.

1. The general control box can be set up on the first floor, and the socket and lighting circuit used on the first floor are placed in the general control box, and the copper core wire of 6mm and 10mm is used between the general control box and the outdoor power supply (depending on the size of the outdoor entrance line). Go to the second and third floors and the power supply can be drawn from the main control box. The main power cord used on the second and third floors can be set according to the total power of the electrical appliances.

If it is only some electrical equipment such as air conditioners, you can consider using a 4mm 6mm main line, so that after connecting to the control box, the wires used separately are used for air conditioning and other sockets. In order to save money, copper core wires can be used for lighting wiring, copper core wires for air conditioning applications, and independent wiring.

The above wiring method will be more convenient for stringing, although it is more reasonable and will save some costs, but it will not be too much.

2. It is best to wiring first and then paint, which will reduce the depth and time of slotting on the wall. The socket and the switch box should be fixed with cement mortar. You need to first determine the location of these junction boxes, open the corresponding wall grooves, and then fix the junction boxes with cement mortar.

The junction box mouth should protrude about centimeters from the red brick wall, depending on the thickness of the cement mortar stucco layer, you can go in a little bit, and the junction box can not be protruding from the stucco layer. In this way, when the cement mortar is painted in the future, the junction box mouth can be basically flush with the wall. Your wall is hollow (empty bucket wall), when the junction box is embedded, you can smash half of the red brick, and the back of the junction box is empty, that's okay.

3. Try not to use sheathed wires, you can use 4 points of wire pipes for pre-embedding. The diameter of the 4-point conduit is only 2 cm, and the depth of the groove is not less than 1 cm, plus the cement mortar stucco layer of the centimeter, so that the conduit can be covered. A 4-point wire can be threaded through three single strands, and your control box is available on each layer, so there are only three wires in a pipe, and there are only two wires in the lighting line.

This is in your own home, and the direction of the conduit does not have to be "horizontal and vertical", as long as you know it in your own mind. In addition, the zero line on the lighting line should not be brought into the switch box, and the control line inside the switch box is (except for the switch with a socket).

4. The grounding wire for rural households does not have to be very standardized. You can use a section of stainless steel pipe with a length of about meters, connect a copper core wire of not less than 4mm from the bottom end, and smash it into the ground, the depth depends on the horizontal plane height you are in, generally to reach the underground wet layer. The other end of the wire can be connected with the grounding wire terminal of the main control box on the first floor.

[1. On the third floor, I put the control switches of the lighting, air conditioning, and sockets on the third floor on the first floor? Or is it better to divide 3 bus lines from a main switch on the first floor to each floor, and then separate various control switches on each floor? That kind of reasonable? What kind of material is more economical? 】

Divide 3 buses to each layer reasonable, but do not save wires; Uniformly placed on the first floor saves money but is unreasonable.

2. The house has just finished bricking, and the cement sand layer has not been paved to the wall, so I want to wait for the cement sand layer to be paved to the wall before slotting and wiring? Or wiring first and then laying the sand layer? How are socket switches and other cassettes fixed (the walls on the second floor of the house in my hometown are erected with red bricks, and the inside is hollow)?

It should be constructed in conjunction with civil engineering, that is to say, wiring first and then laying a sand layer; Socket switches and other cassettes are fixed with thin wire or rope.

3. The operation of the hometown is not standardized, maybe the dark line will also use the BVVB sheath line without the line pipe, and considering that the cost is almost always a straight line (the shortest distance), it will not go at a right angle because of the different heights of the position. Dark laying is to take the nearest route, but what you are talking about is to take a right-angle turn is an open laying, and the dark line will also use BVVB sheathed line without line pipe, which is not allowed in standard construction, since you are an electrician yourself to consider.

4. What should be done with the grounding electrode? (It's the source of the ground line of the house!) Because you haven't touched it, it's harder.

The specific method is to make a grounding strip (hot-dip galvanized 40x4 flat steel) 3 meters away from the exterior wall, at least six meters, and lead out a grounding flat steel (hot-dip galvanized 40x4 flat steel) to the main distribution box of your home in the middle of three meters. On the outside, a grounding electrode is connected to each end of the six meters of grounding flat steel (hot-dip galvanized G50 steel pipe or 40X40X4 angle steel, long meters, one end is sharpened, driven vertically into the ground, and the top is welded firmly with the end of the six-meter flat steel. Six-meter flat steel laying parallel to the wall to a depth of 0,8 m).

If you pay attention to it, then measure the grounding resistance, if it does not reach the specified resistance value, then the grounding electrode needs to be hit a few.

Supplement: If the total height of your house is more than 12-15 meters, it is also troublesome to install lightning protection devices (lightning belts or lightning rods). And it must be connected to your grounding strip, and then the grounding resistance will be upgraded, which is more stringent than the fourth one above.

1. From a main gate on the first floor, divide 3 bus lines to each floor, and then separate various control switches on each floor 2 Wiring first and then lay the sand layer, and fix the wire box with cement 3 Walk in a straight line, don't break it yourself 4 There is generally no ground wire in rural areas, and you should prepare to bury an iron rod deep into it, and fix the wire on it to connect to the electrical box.

Hydropower renovation is an important step in the decoration of a new house, and the quality of hydropower construction has a very important relationship with the quality of our future home life and comfort. It is necessary for the owner to learn how to read the hydropower diagram and know what kind of drawing settings are more reasonable and what kind of drawings are not standardized. Next, I will tell you how to learn to read hydropower drawings and what those difficult symbols mean?

First, how to read the circuit construction drawings for novices.

1. Read the instructions.

The steps to see the circuit construction drawing are to look at its description, including: 1. Where is the installation location of the distribution box, what is the load, and is it reasonable? 2. What is the installation height of the socket, and whether the height meets the full standard of safety and stuffiness?

3. Is the size of the empty opening reasonable, and what is the size of the outgoing protective tube? 4. How about the laying of line pipes? 5. Is the matching of wires reasonable, and is the matching of wires and electrical equipment reasonable?

2. Combined with civil engineering.

Look at the circuit construction drawings to be combined with civil engineering, which should look at the size of the room, the size of the wall, the thickness of the raft, the thickness of the leveling layer, the insulation is internal insulation or external thermal insulation, the thickness of the insulation layer, and the thickness of the decorative layer of the interior and exterior walls; The size of the structural beam, whether the size of the embedded casing is reasonable, what is the building elevation, and whether the height of the room is affected after the installation of hydropower facilities. After these data are available, they can be accurately embedded, reserved, and processed.

Second, how to see the waterway construction drawings for novices.

1. Combined with the system diagram and floor plan.

When looking at the waterway construction drawing, you must combine the system diagram and the floor plan, so that it is more clear and clear, and you know where the turning point of the pipeline is? Where are the water distribution points? Where is the reducer?

What is the elevation of the water distribution point? When looking at the water, it is also necessary to see whether there are corresponding water facilities and drainage facilities, and consider whether the combination is reasonable.

2. Look at the washing machine.

If there is a washing machine water supply point, under normal circumstances, the elevation of the water supply point is completed from the ground, and then look at the drainage floor drain of the washing machine, whether it is a special floor drain for the washing machine, whether there is a water trap, etc. Looking at the waterway construction drawings must have a strong sense of space three-dimensionality, to achieve the feeling that you are standing in the room and following the pipes.

3. The meaning of each type of symbol.

1. The code of the line surface application part.

lm — laid along the roof truss or roof truss lower chord.

zm - laying along the column.

QM – Laying along the wall.

PL - laid along the ceiling.

3. The code of the concealed part of the line.

la - secretly set up in the beam or shed.

za — concealed in the column.

qa—Concealed inside the wall.

PA - concealed in the roof or ceiling.

da – concealed in the ground or floor.

PNA—concealed in an inaccessible ceiling.

2. Line laying code.

PVC – laid with flame-retardant plastic pipes.

DGL - Electrical steel pipe laying.

VXG - Laying with plastic trunking.

GXG - Laying with metal trunking.

KRG – laid with flexible plastic tubes.
