For many home decoration nowadays, there is no problem in our home decoration circuit design is the circuit design and transformation of the hydropower foundation project. For those friends who do not understand this aspect, I believe that for home decoration circuit design is not very understanding! Circuit modification is to start from the switch socket. Initially design your water circuit retrofit route yourself. Here I give you specific details about home decoration circuit design related knowledge, maybe help to you!

Home decoration circuit design steps
First, home decoration, to involve strong electricity (lighting, electrical power) and weak electricity (TV, telephone, audio, network, etc.) circuit lines buried dark lines, wire is very important;
Second, the selection of wire specifications: home decoration, according to national regulations, lighting, switches, sockets use 2.5 square wire, air conditioning to use 4 square wire, water heater to use 6 square wire
Third, the current installation of electricity in many ways, some 12 yuan / square, some 15 yuan / square, the practice is different, the cost of work is also different.
1, the functional approach: the main is not divided into many groups, as long as they can achieve the purpose of electricity, and a three-bedroom, two-room house is divided into four groups of lines.
2, grouping practice: grouping is the first space must be grouped separately, each space air conditioning but also separate grouping, a three-bedroom and two-room need room 3 groups, living room 1 group, restaurant 1 group, 2 bathroom 2 group , Kitchen 1, air conditioning in three rooms to 3 groups, living room air conditioning in a group, a total of 12 groups of lines, each group needs a separate air-to-air control. If you use ordinary PVC pipe threading, it is 12 yuan / square labor costs. The labor cost for threading with a cold bend is 15 yuan/square, because each bend requires a bender to make an elbow, which is time consuming and expensive. Strong and weak electricity slot layout, to add 3 yuan, is 18 yuan / square, plainly is to increase the slotted money.
3, the national standard's practice will be 22 yuan, completely open horizontal slot, only open vertical slot.
IV. Basic principles of hydropower construction
The principle of hydropower construction is that if you walk on the roof and the roof cannot go, consider taking the wall and the wall can not go before considering the ground. The top line is inside the ceiling or the plaster line. Even if there is a fault, maintenance is convenient. The loss is not great. If all is gone, the overhaul will guide the lift of the floor. The ground is a concrete structure. To bury the line, it will inevitably hurt the concrete layer and even the reinforcement.
1. Positioning: First of all, according to your use of electricity for circuit positioning, for example, where to switch, where to socket, where to light and other electricians will be based on your requirements for positioning.
2. Slotting: After the positioning is completed, the electrician will open the wiring slot according to the positioning and circuit direction. The slot is very particular and should be horizontal and vertical. However, the normative practice does not allow the horizontal slot to be opened because it will affect the bearing capacity of the wall. .
3, wiring: wiring is generally buried in the way of the line tube. There are two types of wire tube: cold bend tube and PVC tube. The cold bend tube can be bent without breaking. It is the best choice for wiring because it has a radian, and the wire can be replaced at any time without opening the wall.
4, elbow: cold elbow to use the elbow tool, arc should be 10 times the diameter of the line, so that threading or stitches can be smooth.
Home decoration circuit design 21 matters needing attention
(1) The design of the circuit must be determined in detail after considering the possibility, feasibility and availability. No one wants to pull wires on the floor of a new home. At the same time, the circuit design should also pay attention to its flexibility, and sometimes it should not be too "consummate." Summarize a relatively simple principle: consider the next plug-in board in the position where the electrical plug is relatively concentrated, the effect is often better than the wall-mounted socket;
(2) The bedroom ceiling light can be considered double control (bedside and entrance);
(3) According to the needs of living, the ceiling light of the living room can be installed with the switch (into the entrance hall and back to the main bedroom door);
(4) Observe whether there are modules in the telephone socket and the network cable socket;
(5) The surround sound line should be buried when the circuit is modified.
(6) Note that strong and weak wires cannot be in the same pipe and there will be interference;
(7) If the living room, kitchen, and bathroom are tiled, some locations may be properly considered without slotting;
(8) The socket is generally 30CM away from the ground, not less than 20CM, and the switch is generally 140CM away from the ground;
(9) The exhaust fan switch and telephone socket should be installed near the toilet instead of the wall of the bathroom door;
(10) The Yuba should be considered to be installed near the shower room or bath instead of the central position of the bathroom;
(11) Reservations for sockets may be considered for balconies, corridors, and cloakrooms;
(12) Spaces with mirrors and coat hooks should consider the lighting near the mirror;
(13) In the living room, master bedroom, and bathroom, the telephone line should be considered according to personal habits and convenience;
(14) A maximum of eight lines in a tube, and remember: each tube gap can not be less than 40%.
(15) How to charge the cassette must be stated in advance. This is the most hidden and darkest profit point for the transformation of the water circuit. A cassette market is also one or two dollars, while the decoration team often charges more than ten dollars, and the average home improvement needs a small number of cassettes to be five or sixty. Therefore, it is normal for students to throw a few hundred dollars for this. Death is resisting pulling it out today. It has only one purpose. We remember five words: cut it down!
(16) The position of the socket is very important, and often the socket is just behind the bedside cabinet, causing the cabinet to not be against the wall. It is generally not wrong to let the outlet be as close as possible, but if you leave the location of the outlet improperly, it may conflict with the placement of the furniture or the installation of the electrical appliance in the later period. Students must remember;
(17) The sockets of some kitchens are also convenient with switches, so as to avoid the inconvenience of pulling and unplugging the rice cooker plugs from time to time, for example.
(18) There is no need to set too many sockets behind the TV. It is better to put a socket board on the side of the TV afterwards.
(19) In electrical codes, buried pipe must be PVC pipes and heads must be changed.
(20) Circuit modification It is necessary to increase the line capacity according to the use of household appliances.
(21) Clear communication intentions and design ideas with workers. And on the wall bullets painted actual circuit transformation route.
Editor's summary: Water circuit renovation is the most important point of renovation, to consider the location of various electrical appliances; the location of the upper and lower water; outlets, Yuba, light lines must be reserved ... ... if these problems do not think well beforehand, once After completing the water circuit, it will be troublesome. Therefore, before the transformation, we must think of as much as we can think of, we can set a good, and communicate with the construction team in advance, and prepare in advance, so that we can minimize the regret.
