As we all know, the installation of hydropower is like the blood of the whole building. It is a crucial link in the construction project. The installation quality is closely related to the overall quality of the construction project and directly relates to the service life of the building. If the installation is unqualified In serious cases, it may even endanger people's lives and cause huge economic losses. Therefore, the following Xiaobian introduced the hydropower installation and construction regulations and the precautions for hydropower installation.
Hydropower installation and construction specification
1. The principle of wiring: horizontal and vertical. Use special PVC flame-retardant wire tubes, the wire tube must be fixed in the wire trough, use the lock mother when connecting the wire box and the wire tube, and use a tube card every 80 centimeters for the straight tube. Use a tube card every 20 centimeters around the corner.
2. In the upper part of the wall, the socket shall be vertically slotted upwards until the top of the wall is installed in the installation line of the decorative corner line. If it is in the lower part of the wall, it shall be vertically slotted downwards to the bottom of the installation skirting board. The depth of the slot shall be Consistently, the slot line and the top line should be ejected after the control line on the wall, and then use a cutting machine to cut the wall surface and slot the machine.
3, the use of financial PVC pipe, in the elbow when the spring is bent, not to use 90-degree elbow and three links (at this point we basically did not appear this type of situation), line installation must be sheathed Glue is used for connection. The edge of the casing shall be tightly closed. Flat and smooth. The right angle shall be cut at the inside of the corner. After the arc-shaped interface is cut at one side of the incision, it shall be bent and installed.
4, moderate depth of pipe teeth, no burr. The pipe joints are wrapped with raw material and wrapped 5-6 turns. The number of pipe twisted teeth is 5 teeth-6 teeth until the joint is tightened, and rotten teeth are not allowed to enter the pipe.
5, after the wire is installed into the casing, the wire fixing tool should be used. After fixing the wire inside the wall and the wall, the plaster is concealed.
6. It is strictly forbidden to lay the line pipe directly under the composite plate. (At this point, we have not done very well at present. We will communicate with the customer well later, and the composite floor must be grooved.) The line pipe under the solid wood floor There must be reinforcement measures.
7. It is forbidden to lay the line pipe on the kitchen or bathroom floor to prevent water from penetrating into the line pipe.
8. The conductors that enter the line pipe should not be more than 40% of the hole area of ​​the line pipe. The conductors in the pipe must not have connectors. The conductors of different applications must not be mixed in a line pipe.
9, the wire into the box must be guaranteed to leave a certain length, leaving 10 to 15 centimeters, leaving 100 centimeters of sound, wear a hose in order to switch the installation and maintenance of the socket.
10. The distance from the wall to the water pipe should be 1.5cm, left and right cold, and 15cm apart.
11. The parallel distance between the wire and the water pipe should not be less than 30 centimeters, and the crossover distance should not be less than 10 centimeters.
12. Wire points and points must not have joints, and the dark lines in the ceiling must have flame-retardant tube protection.
13. After the acceptance of water and electricity is passed, powder lined trough and wall trough can be filled and compacted with 1:3 cement mortar.
Hydropower installation and construction specification
1, before the installation of water and electricity must be done by a professional designer for you to do a good floor plan, and then according to the floor plan for the entire room for hydropower positioning, in order to ensure that the late faucets and switches, sockets will not be misplaced, missing a lot of equipment Home Appliances do hydropower to find the results of some unprofessional plumbers, go directly to the scene to talk about, drawings are not, resulting in regret after the bottling. Either the headboard is blocking the outlet, or the faucet is not in the correct position, and some even use the socket when it is not installed.
2, after the positioning of water and electricity, is to check their own water pipes, the first is to check whether the leaking water test, the second is to see if the water is then check the water upstairs households are leaking, if there is no problem with their own water pipes, then it is necessary Use professional water protection caps to avoid falling into brick slags when plugging the cable trunks. If there is a problem, it can be easily eliminated before the decoration. It can be said that most plumbers and heads of households will miss this step, etc. After the completion of the installation, it was found that the water pipe was not working and it was not good to handle the responsibility.
3, bomb horizontal line, this simple horizontal line can ensure that the late switch socket are on the same line, when it is a few five holes inserted together, many workers directly from the ground with a tape measure is not allowed to Now, the rough room interior level may differ by 5 cm, so that the switch sockets in the later stage will not be on a horizontal line, which will have an extremely bad influence on the appearance of the entire decoration. There is also a diagonal line of the ceiling light.
4. The diagonal line of the top light must be played so that it can ensure that the light in the later stage is in the middle of the top. Therefore, friends who are going to install water and electricity should pay attention to it. In fact, it seems to be inconspicuous that it plays a very large role. The details of the success or failure of this statement are really insightful.
5, is to open the trunking, which is the wire and the water pipe had to go, in order to ensure the simple post-maintenance, water pipes and wires should be horizontal and vertical, especially the best water pipe ceiling, the fewer joints in the wall, the better, do not I believe that there is a 100% non-perishable product in the world, and when the aircraft has fallen, it is certainly a waste to do so in terms of timber. This method can accurately find the line pipe and the water pipe when painting a hydropower project drawing, if it is oblique Obliquely so that the water and electricity project drawings are not allowed to be drawn, the exact location of the line pipe and water pipes can not be found, so choose which approach to consider slightly.
6, open the trough is the laying of the bottom box, laying the bottom box is directly affect the quality of the final decoration effect, why do you say, if the bottom box is installed when the oblique then the switch socket panel installed later must also be oblique , The bottom box installation mainly pays attention to the following points; (1) When installing the bottom box must be sprinkled water, (2) can not be higher than the original wall, (3) is to be level, (4) strong and weak electricity should be interval 15- 20 cm (to avoid weak interference), (5) It must be locked when the bottom box is installed so that the cement mortar will not enter the bottom box and cause corrosion to the wire.
7, is the circuit is installed, for a room with three bedrooms, two bathrooms, two bathrooms, one kitchen, at least five circuits are required for strong power, namely, a circuit of the socket, a circuit of the switch, a circuit of the air conditioner, a circuit of the two bathrooms, and a kitchen. A loop, doing so can reduce the load on the wire, and the second is that when the lights or sockets are replaced later, they do not run out of power. There is also the best way to separate the strong and weak power, that is, the strong power goes overhead and on the wall, while the weak current is You can walk on the ground to do this to completely avoid interference with weak electricity.
8, the installation of water pipes, water pipes seem simple, but once there is a problem, it is hurt, hurt, so we must pay attention to the following to everyone that is safe and easy to maintain method, that is, the best of the plumbing supervisor to take the smallpox, The faucets assigned to the sanitary wares should be divided into single pipes directly from the supervisors on the top. Only one inner wire elbow is placed in the wall. This will not affect the downstairs even if the water leaks later, and maintenance is particularly convenient. Remember that everything is in order. So I would rather use more water pipes now instead of having headaches for leaking water later, and then suppressing this link will definitely save the province.
9, drainage pipe installation, there is no special method here, mainly after the completion of the check whether the location of the drainage is consistent with the drawings, there must be done through the water test, and then with a professional water protection cap can be, Must be covered, or the consequences will be serious.
10. The first is to check whether all the circuits are energized, whether the weak electricity is on, water pressure, drainage water test, and then must refer to the drawings to check whether the position size is consistent with whether it is missing the equipment, and there is to check whether the finished product protection is in place.
Editor's summary: The specifications for hydropower installation and construction and the precautions for installation of hydropower are introduced here. I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
