The most common ones are power lines, telephone lines, network lines, TV signal lines, and various lines of sound systems in our listening rooms. Usually the decoration is so complicated that we can't pay enough attention to this piece. Not to mention the construction party, there is very little professional electrician to provide you with formal electrical construction. If these concealed projects are not handled properly, they will bring endless troubles and even irreversible losses to future electrical construction and future use. Therefore, it is necessary for us to understand and master some of the decoration knowledge, so as not to regret it!
There should be a necessary design before electrical construction, although it is inevitable that there will be modifications during the specific construction process, but this design must be there. The general principle of electrical design is that weak electricity makes strong electricity, and strong electricity makes equipment. However, in the specific design, it is still necessary to take into account the convenience of weak wiring.
Specific to the wiring construction, if your ground is paved, whether it is composite or solid wood (bamboo), I suggest that you wire the wire as far as possible behind the skirting board, just in the wall, door or wall A small line pipe is pre-buried to the back of the skirting board. There should be no dead bend in the middle of the line tube. The lead wire is left in the tube. When the floor is finished but the skirting board is not installed, the wire is put in. After installing the skirting board, you will not see any traces of the traces, which is very beautiful. This construction method has the following advantages: 1. Since the floor is laid in the final stage of the renovation project, and then threading when laying the floor, it can effectively prevent accidental damage to the wire during the long construction period; 2. You can Have more time to choose the right wire; 3, when you want to change the line, add the line can be, remove the skirting board can be constructed, very convenient; 4, because the line pipe does not go under the floor, so do not have to cut the solid wood (bamboo The wooden keel under the floor (except for the line tube and the wooden keel), thus improving the construction quality, reducing or even avoiding the possibility that the solid wood (bamboo) floor will be slammed; in the northern area, the keel can be prevented. , solid wood (bamboo) floor joints due to the increase in drying and affect the appearance; 5, can save most of the cost of buying a line pipe. In fact, workers who lay the floor are not willing to construct a line of spider webs, because that will affect the speed and quality of construction. This is a construction method that benefits both parties.
If your floor is a tile, it is best to pre-embed the conduit. The function of the conduit is not only to protect the wires, but also to facilitate the replacement of the wires. Therefore, the middle of the pre-embedded line pipe can not be bent at right angles first, and the method of turning the corners should be used to solve the turning problem, so that the wires can be freely moved in the line pipe. The so-called nesting bend, that is to say, the section of the line to be bent into a circular arc with a radius of not less than 15cm, to complete a variety of different angles. However, the corner is quite special. It takes two quarters of a circle to turn the 90° dead bend into a bend. The first quarter turn turns forward to the left or right, the second one The /4 circle turns the level into vertical. Only in this way can the 90° bend of two vertical planes be completed. See the schematic. (The nesting spring can be placed on any part of the wire tube by wire or wire.)
Secondly, the wire tube is preferably made of a plastic coil (a type that is generally used in semi-rigid, translucent, and regular construction), so that there is no joint in the middle of the line tube, so that the line is not caught when threading. If there must be a joint in the middle, also use the size of the head to insert, and the direction should be the same. Then there is no need to rush the thread in the line during the construction, but first thread the lead wire, and then replace the corresponding wire when the electrical installation is final. This is very important! The benefits of this construction method are self-evident.
The final emphasis is that strong and weak electricity should be separated from the wiring. The power line is a strong power. The larger the load is, the stronger the electromagnetic wave interference is generated. Therefore, the power line should be separated from the weak current and low voltage wires as much as possible.
All of the things I mentioned above belong to the minimum content of green decoration. As long as we make requests according to this, every decoration team should be able to do it unless they deliberately cut corners.
