I. Hydropower projects
Hydropower renovation and waterproof treatment are two hidden projects that need special attention in hydropower decoration.
1, the number, location, size and height of electrical appliances to be used in the future, as well as the convenience, rationality and feasibility of the circuit should be fully considered in the circuit design. These problems are not handled well, the circuit installation is unqualified, and the wires behind the wall are easy to cause safety hazards.
2. In general, the wiring of the circuit adopts the way of buried conduit. It is suggested to bury the buried conduit with PPR, and there must be a panel where there is a joint for inspection.
3. Pay attention to the horizontal and vertical pipe laying, and use a professional pipe bender at the elbow. Do not bend or turn hard. 20CM at the nozzle must be fixed with a pipe clamp.
4, socket installation height should be reasonable, too high or too low is not good, too low will be blocked by furniture and other items, too high is not convenient to operate. Generally, the socket is 20-30 cm away from the ground, and the switch is 120- 130cm away from the ground. Special circumstances can be considered flexibly. Pay attention to the waterproof sockets in balcony, bathroom and kitchen. 、
5. The weak box and the strong box of the main circuit box are separated. High-voltage air conditioning, hall, lighting, kitchen and bathroom all have their own circuits, and each circuit is wired separately. Weak current reaches the main chassis independently in various ways. In order to ensure that each road does not interfere with each other, it can be cut off independently to prevent accidents.
6. It is recommended to use brand fittings with good quality for water pipes and fittings. Maintaining them in the case of infiltration is not only troublesome but also a waste of money. It is best to choose materials from the beginning.
7. The floor drain of washing machine does not need to be sealed in deep water. If the deep-water floor drain is not well sealed, it will not drain or overflow. Deep-water sealed floor drain is suitable for places with small displacement, and the floor drain with large displacement at the washing machine can not meet the requirements.
8. The distance between hot and cold water pipes shall be 15cm, and the height of hot and cold water pipes shall be consistent. Hot and cold water pipes are perpendicular to the wall and cannot be tilted. The water pipe should be two centimeters higher than the wall for subsequent bricklaying.
9. After the drainage pipe is installed, a drainage test should be conducted. Try to go to the site during the test, and the test time should be at least 30 minutes.
10, the pipes connecting the bathtub and the faucet of the shower are embedded in the wall, so don't make a mistake in size, or it will be difficult to install the faucet later.
waterproof treatment
1. Waterproof works in different spaces have different construction methods. It is suggested that the waterproof layer of the bathroom be painted to the top, the kitchen space be generally painted 1 m, the wall surface be waterproof by 30 cm, and the door cover be painted twice.
2. After the waterproof project is completed, start the "closed water test" and conduct the waterproof test for 48 hours. After that, check whether there is water leakage, and rework immediately if there is water leakage.
Second, bricklayers
1. When buying cement, it is recommended not to choose cement with a production date of more than 3 months, and not to mix different brands of cement.
2. You can buy more tiles to prevent color difference when you buy them again.
3. Walls and tiles need to be soaked in water and dried before use.
4. When laying tiles, you can stick some imperfect tiles in some invisible places, such as behind the sink and behind the mirror frame.
5. White cement hooks are not recommended for tile jointing. After a long time, it is easy to become black seams, which is ugly.
Third, carpentry
1. Before construction, indoor log materials should be treated with fire prevention and moisture prevention.
2. Before woodworking construction, the entity of 1: 1 needs to be released in the construction area according to the construction drawings and renderings.
3, wooden door installation, carpentry door cover and bricklayer's tiles should also cooperate. When you cover the door cover, if the tiles are not laid, it is easy to get cement on the door cover when you use cement to lay tiles in the future.
4. The ceiling fan cannot be installed on the ceiling keel.
5. The bottom of the bathroom door cover should be waterproof.
Fourth, paint.
1. Before construction, protect some furniture that doesn't need painting or the wall that will be touched.
2. You can brush a thin layer of paint on the surface of the furniture that needs to be brushed and seal it, which is beneficial to the stability of solid wood furniture and the repair of the interface.
3, paint acceptance link. Check whether the surface color of furniture is consistent with the color sample, whether the surface color is full and uniform, and whether the nail holes are useless. It is smooth and delicate to touch with your hands, and it is qualified if there are no bubbles.
4. After acceptance, the finished product can be protected. Wood products are cleaned and wiped with soft cloth and sealed with professional protective film.
