What are the steps for the installation of water and electricity in building decoration projects

Step 1: Slotting.

Play the line first, then groove. The pipeline slotting must be parallel lines and vertical lines as required (if there are hydropower construction drawings, it is better to compare construction drawings). The pipes of the horizontal walking line must be controlled at a height of 60-90 cm (from the ground), and the pipes with faucets must be vertical.

Step 2: Installation.

The pipes are divided into cold water pipes and hot water pipes. Hidden pipes do not use galvanized iron pipes. First of all, through the construction drawings, the construction personnel discuss the location and function of the water area with the owner.

Arrange for the plumber to drain and install all the taps and water locations. If there are construction drawings, they can be placed according to the construction drawings. If there is no complete drawing, communicate with the owner to increase the on-site positioning waterway use function.

Step 3: Inspection.

The inspection of waterway pipelines is very important and related to the future waterway safety hazards. We usually use the method of pressure testing to do pipeline inspection. Pressure test is one of the methods to check for leakage in the pipeline, and all the inner wires are blocked with a plug first.

Use a pressure gauge to press (generally 6--8kg for home improvement) to test the water. After compression, inspect all pipes and joints. The second method is to open the sluice gate for two days and two nights, and check all the joints on the third day.

Normally, take the previous method.

Step 4: Waterproof.

After the installation of the water pipes, seal all the wiring grooves of the bathroom with cement and sand mixture (the floor of the bathroom and kitchen should not be grooved as much as possible). After the trunking and the ground are dry, clean the ground and wall again, and the wall and floor can be waterproof when the moisture is dry, and the wall waterproof is best to be more than 80cm high. If there is a furniture wall behind the kitchen and bathroom wall, it must be made all over the wall.

It plays the role of moisture-proof furniture. The first time you enter the site is to be able to make sure that the ground will not leak. After the pipe is installed, the wall and the floor are done again, so that the ground and the wall can be more effectively waterproofed.

When accepting hydropower projects, it is necessary to test whether the waterproofing is qualified.

Step 5: Circuit slotting.

After discussing the electricity functions and requirements with the owner, explain the bottom with the electrician master, and play the parallel and vertical lines and grooves. Put away the switch socket bottom box. The socket is slotted 40 cm from the ground, the hanging air conditioning socket is slotted from the ground, and the switch is slotted from the ground.

The bottom of the switch and socket should be slotted with the horizontal line. The kitchen and bathroom room must be slotted according to the designed use function. There must be a lock in the secret combination.

Step 6: Circuit routing.

Normal household copper core wire above square meters, wire pipe above 16mm. Strong and weak conduits should be separated from concealed combinations. The wiring of strong and weak electricity is separated by 30 cm at the lowest limit, and the wires of more than 6 square meters are grouped for air conditioning sockets, 4 square meters for electrical sockets, and more than square meters for switches.

The air conditioning line group is more than 2 meters from the ground. Electrical wiring group ground wiring, switch and lighting wiring group wall top wiring. The switch socket must be installed horizontally and vertically when the bottom is closed, so that the rear panel installation will be more flat.

When decorating the house, water and electricity is the basic project, and it is also the most important decoration project. Many people are very curious about the process in the installation of water and electricity, and also curious about related installation matters, what are the precautions for decoration water and electricity installation?

First, the process of decorating water and electricity.

1. Slotting. The line is played first, and then slotted, and the pipe slotting must be parallel and perpendicular according to the requirements. For the pipe of the flat walking line, the height of 60-90 cm is always controlled, and the pipe with faucet must be vertical.

2. Installation. The pipes are divided into cold water pipes and hot water pipes, and the use of galvanized iron pipes should be eliminated for hidden pipes. Through the construction personnel and the owner to discuss the water area and use function, arrange the water and electricity master to discharge all the installed faucets and water locations.

If there is no complete drawing, communicate with the owner to increase the on-site positioning waterway use function.

3. Inspection. Waterway pipeline inspection is often important, and special attention will be paid to waterway safety issues, we can do pipeline inspection through pressure test method, pressure test is one of the methods of pipeline inspection leakage, you can plug all the inner filaments first. Use a pressure gauge to press (generally 6--8kg for home improvement) to test the water.

After compression, inspect all pipes and joints.

4. Waterproof. After the waterway pipeline is installed, seal the line groove of the bathroom with cement and sand, and after the line groove and the ground are dry, clean the ground and wall again, and the wall and floor can be waterproof when the water is dry, and the wall waterproof is best above 80cm high. If there is a furniture wall at the back of the kitchen wall, it must be made full of walls, which can have a good moisture-proof effect.

5. Circuit slotting.

After discussing the power functions and requirements with the owner, you need to explain to the electrician, and play the parallel and vertical slotting. Then put the switch socket bottom box, the socket is slotted 40 cm from the ground, the hanging air conditioning socket is slotted from the ground, and the switch is slotted from the ground.

2. What are the precautions for decoration water and electricity installation?

1. Do not operate with electricity.

In order to prevent electric shock, it is best to install the circuit after the power is off, and it must not be operated with electricity. After installation, it is necessary to check that there is no problem before the power test machine can be powered on, in addition to checking the relevant performance in the test machine, the shell should be checked whether the shell is live, and the electrical equipment with live shell can not use the fingers, and must be overhauled in time, otherwise it will be electrocuted and cause injury.

2. The voltage should be calculated.

Before installing household appliances, you must carefully check whether the use voltage of electrical equipment and the power supply voltage are consistent, if it does not meet the electrical appliances, it will be damaged, resulting in greater losses such as fire houses, if you need to install and use must cooperate with the transformer. The power supply of household appliances is often provided by indoor sockets, and the power sockets of household appliances should be two-pin sockets, and two-core plugs should be used for well matching. When installing electrical equipment, the switch should be installed in the live wire, otherwise when the switch is disconnected, the electrical equipment will be electrified.

The process of decorating water and electricity is as above, and the master of general decoration can help the owner to do a good job in water and electricity construction, and the main thing to do is to complete it step by step when decorating. What are the precautions for decoration water and electricity installation? There are so many things to pay attention to, and it is recommended that owners can do a strategy before installation.

The decoration of water and electricity in life is an important part of our house decoration. The renovation of hydropower is a very large construction project. It's easy to make mistakes during renovations.

Therefore, we must pay more attention to the renewal of hydropower, so, what are the steps of hydropower renovation construction? What are the precautions for water and electricity decoration construction?

First, the construction steps of water and electricity decoration.

1. Hydropower positioning.

The plumber of hydropower decoration construction first determines the position of the switch socket and the location of the navigable waterway interface according to the needs of the user. Also pay attention to the water pipe that passes through the roof, the strong and weak electricity should walk on the ground as much as possible, and the strong and weak electricity cannot be crossed, and the parallel distance is more than 30 cm from the over-disturbed type.

2. a distribution box.

The installation of the electrical box must be considered for convenience, concealment and safety. At the same time, it must be taken into account that it is directly connected to the external main line and that the circuit cannot be hidden in the walls of the building or in the load columns.

3. Circuit design of plugs, switches and lights.

The space for new inserts and changes in line for the construction of plumbing renovation is also different to avoid subsequent time and effort. At this time, we must take into account the changes in the interior space and prepare for the different uses of the space.

4. Lamps. In the case of heavy luminaires, it is necessary to pay attention to the load elements on the roof at this time. Do not install the wooden wedge directly, otherwise it may cause unsafe factors.

5. Slotting. It must also be kept straight when grooving, and there should be no dents on the sides of the slot. Before grooving, have the plumber place all the waterways and circuits on the wall.

6. Waterways. When rebuilding the waterway, it is necessary to pay attention to the size of the water pipe in the original room. The pipes of the external water pipes are preferably matched to the original water pipes. Hot and cold water pipes must also be relatively pointed, usually not less than about 20 cm apart.

2. Precautions for hydropower decoration construction.

1. In the wiring of water and electricity, the function and ability of the kitchen and bathroom should be considered. The grounding requirements in these two places are relatively high. Therefore, it is better to use bumper wiring wires in the kitchen and bathroom, but it is not possible to lay the route on the floor.

It was necessary to walk along the walls of the roof. If it is routed on the ground, the waterproofing layer will be damaged somewhat.

2. Generally speaking, the reconstruction of the waterway will not be from the top to the ground, the hot and cold water will remain in a horizontal position, usually on the right side. The layout of the road must be horizontal and straight, and the distribution of pipes must be safe and reasonable. The position of the fixture and the slope of the pipe must meet the requirements of the code.

All types of valves must be installed in the correct position and level to facilitate their use and maintenance.
