The renovation of the house has been almost half a year. From the very beginning, I could hardly understand anything. Up until now, I have gradually experienced my own experience in the constant torture and beating. These experiences are personal experiences and feelings in the actual combat process. I think there are many friends who are currently refurbishing and are about to refurbish. I think we should share this with you. So there is the following text.
First of all, I would like to talk about hidden projects.
In fact, hidden projects are quite complex, including a series of projects such as wires, water pipes, gas, telephone lines, and network cables. Let's talk about wires first. Wires are mainly divided into several categories: lighting lines, outlet lines, and air conditioning lines. In principle, the quality of electric wires is now available in newly built houses, so it is generally not necessary to re-arrange them unless you know that your home's wires are not working or that you are not worried about money. Therefore, as long as the wire part is increased and extended as needed, it is sufficient.
In general, 1.5 for the lighting line, 2.5 for the outlet line, and 4 for the air conditioning line. The air-conditioned lines are now in good condition. Therefore, under normal circumstances, no increase in air conditioning line. The wire is recommended for pandas. In addition, it should be noted that the Yuba wire should also use the outlet cable, that is, 2.5, if the conditions, using the 4 is the best.
Actually, in this aspect of electricity, in addition to the wires themselves, there are also PVC pipes that run through the wires. This is where we need to pay special attention.
Since this part of the wire is all in the light, it is generally not possible to have hands and feet. The most problematic place is the line management. The first is the quality of the line pipe. The quality of the wire tube must be good, put on the ground with the foot, at least not easily stepped on the bad, this is the most basic requirement. You TX can test your feet.
The number of pipes to wear is also the place where workers like to play tricks. Today's PVC pipe generally has two points and four points. Use 6 points if conditions permit. And indicate in the budget.
A 4-point tube can only wear 1.5 light lines, and a maximum of 3 wires can be used in a single tube. 6 points of the tube can wear 2.5 wires, and a maximum of only 3 wires can be worn in a tube. These are all valuable construction regulations. They must not be sloppy or be deceived by workers. Perseverance is victory, or else you will lose yourself in the future.
Tell me why. There are two main reasons why wires run through PVC pipes. One is because of protection and insulation; the other important reason is to guarantee future maintenance. Just think about it. When the concealed projects are all done, one day, if a wire is out of order, it can be pulled out through a PVC pipe and replaced with a good one. If you wear too many wires in the PVC pipe, you will not be able to pull it, and there will be no future repairs.
In addition, PVC pipe joints must be used when docking, and glue should be used to secure the joints. In addition, the connection between the PVC pipe and the wire box must use a dedicated cover, do not directly use PVC pipe and wire box docking.
These may be details, but details are not resolved after the hidden problems, I hope you must pay attention to TX, do not slacken yourself, do not expect workers to help you think of problems ah.
Therefore, the normal operation specification is to first arrange the PVC pipe, connect the pipe, and then insert the wire. Unfortunately, most of the workers nowadays do not regulate their operations, that is, they are connected to the pipes while wearing wires. Oh, it is really difficult to ensure that the wires can be replaced smoothly.
What I just said is strong electricity. There are weak electricity, that is, telephone lines, network cables, cable television lines, audio lines, video lines, audio lines and so on.
The method of weak electricity is almost the same as that of strong electricity. Of course, wear PVC pipe. The cross section of the wire does not exceed 40% of the PVC pipe section. Again, don't wear too much. Moreover, strong and weak electricity must not be worn in the same pipe. And to try to separate, the distance between strong and weak electricity is at least 20 centimeters or more, otherwise there will be interference, remember, remember.
A conditional TX can use a network cable instead of a telephone line. That is, both the telephone line and the network cable are lined with a network cable. Because the network cable has 8 lines and 2 of the telephones are used, the risk of accidental disconnection can be effectively reduced, and the probability of failure of the telephone line is indeed high.
Here, we must no longer mention the quality of the line itself. Due to the general situation, TX pays more attention to the quality of wires, which leaves workers with a chance to paste. Therefore, it is also necessary to pay attention to the quality of network cables, telephone lines, and cable television lines. Recommended general conditions are using Panda's. Everyone may know the panda's wires. In fact, Panda's network cable, telephone line, and cable TV line are of good quality. Oh, after all, it is a brand name. Touching it with your hand, the texture is not the same.
Audio and video lines are recommended to buy. Because this kind of line is more expensive, the difference between good and bad is too big, it is more secure to buy oneself.
Let's talk about plumbing now.
There are also many options for water pipes, such as PPR water pipes, copper pipes, copper plastic pipes (aluminum plastic pipes), PVC pipes, iron pipes, and so on.
In fact, PPR hoses are ideal for a variety of reasons. The reason is very simple. First of all, a good PPR pipe is very reliable in quality and can be comparable to a copper pipe. There is also a price that is relatively easy to accept and much lower than a copper pipe. There is also an important point that it is healthy and there is no rust. Copper rust. PPR hoses recommend Pilesa, which is currently the best PPR hose in the market. It is recommended that TX do not save money in this regard.
Note that the water pipe must be 6 points. Pirsa's PPR pipes are divided into cold water pipes and hot water pipes. The key is the difference in the thickness of the pipe wall. It is recommended that everyone use hot water pipes to arrange the pipes. The pipe wall is thicker, the quality is better, and the price is not much more expensive. .Before laying the water pipes, everyone must communicate with the workers fully. Do not give the workers any opportunity to deliberately prolong the disputes caused by the water pipes. But here it is important to emphasize that once you find that the water pipe is prolonged for no reason, it must be corrected by the worker under any circumstances. Because this is not a simple calculation of the water pipe, it will affect the use of water, especially the use of hot water. Hot water pipes run too long and hot water will not meet design requirements. You must pay attention to TX!
The water pipe is recommended to walk along the top of the wall, use ceilings, etc. Do not walk under the floor. Once you leak water, you will regret it. Therefore, it is also very important to test the pressure of the water pipes after the water pipes are arranged. At the time of the test, everyone must be present, and the test time should be at least 30 minutes. The conditions permit, preferably one hour. Ten kilograms of pressurization, and finally there is no reduction to pass the test.
Another point is that people are most likely to neglect. The water pipes need to be fixed. Do not invisibly see the water pipes installed in the ceiling. Second, they can't get out of the ceiling. They think they don't need to be fixed. In fact, the important reason for fixing is to minimize the sound of water flow. Oh, this is all construction specifications for the renovation, we must pay attention to ah.
There are specific ways that TX asked me to modify the plumbing with a ceiling. I'll talk about it in a little detail here.
The essence is to pipe the water pipes according to the principle of the shortest path along the top corner of the wall. Re-emphasize that the water pipes must be fixed, with special fixtures, and they should be fixed roughly every one meter. Conditions permit can be fixed every half meter. There are many advantages to such a row. First, save labor costs, do not chisel walls. Second, hot water pipes have moderate expansion, thermal expansion and contraction, too long tubes buried in the wall easily damaged. Third, in case of water leakage, you can immediately know, and the loss is small. If you are under the floor, the floor is bad. 4. Relatively speaking, maintenance is easier.
Of course, such a row must be specified at the time of design, that is, the route of the water pipe should be linked to the practice of the ceiling. Be careful to communicate fully with the designer. Avoid the disconnect between theory and practice.
