What should I pay attention to in decoration acceptance?

For concealed waterproof projects, the most important thing is to be meticulous in construction. First of all, before the decoration, the construction personnel should do a 24-hour closed water test. After making sure there is no leakage, they should clean up the ground debris, shovel off the loose parts, then smooth the uneven places with cement mortar, and then smooth the bedding face. The closed water test can also distinguish and determine the responsibility of waterproof engineering, and the responsibility for leakage lies with the developer; There is no leakage after decoration, and the responsibility lies with the decoration party.

If the bathroom is waterproof, water will splash on the adjacent wall when taking a bath. Without the protection of waterproof layer, the next wall and diagonal wall are easy to be damp and moldy, so before laying wall tiles, it is necessary to waterproof the wall. In general, the wall should be waterproof with a height of 30 cm, but the whole wall should be waterproof with a height of at least 1.8m, and special attention should be paid to the corner to prevent dripping. In fact, most waterproof layers leak at corners, so as long as these places are well done, the possibility of water leakage will be reduced.

Second, check the walls and keel.

If the wall and keel violate the operating rules, they will not be easily found. For example, due to the whole or partial collapse of the ceiling, the ceiling has become a "roof collapse".

Third, check the ceiling.

The ceiling and floor, keel and decorative board are not well combined, or the load is too large, which is easy to cause "roof falling". According to the regulations, the ceiling keel shall not be distorted, and the installed keel shall be solid and reliable, and the horizontal deviation around it shall not exceed 5 mm; No chandeliers and ceiling fans weighing more than 3 kg can be hung on the ceiling keel, but hooks should be set separately. If the ceiling is decorated with gypsum board, its thickness should be about 9 mm

Fourth, check the odds and ends

1. Mixed hot and cold water pipes White is cold water pipe and red is hot water pipe. Mix cold water pipe and hot water pipe. There are hidden dangers: the hot and cold water pipes have different rates of thermal expansion and cold contraction, and the cold water pipes are cracked and leaked due to thermal expansion and cold contraction. Standardized operation: distinguish hot and cold water pipes by color, and operate strictly.

2. Standard operation of using glue: At present, there is no pure natural and pollution-free glue on the market, and the substitute is 108 glue. But we must look for better brands and products with test reports.

3. The wires are not insulated. During construction, the wires are directly buried in the wall, and the wires are not covered with insulating tubes, and the wire joints are directly exposed. There are hidden dangers: this is not safe, and the wire may be damaged and shorted for some reason, such as aging of the wire. At the same time, once the wire is broken, it is impossible to change the wire, but it can only hit the wall and knock on the ground. Standard operation: wire laying must be wrapped with insulating sleeve, and circuit connectors should not be exposed, but should be installed in boxes, and no connectors are allowed between boxes.

4. Dismantle and change the waterway at will. If the owner does not know how to decorate, it will mislead the owner to dismantle and change the waterway at will, wasting money. There are hidden dangers: wasting money is only one aspect. Once the waterway is improperly sealed or lacks pressure test, the water pipe will burst. Standardized operation: move when the pipeline should be changed, and do not move when the pipeline should not be changed.

5. Strong and weak electricity are put together to cut corners. Strong electricity (such as lighting wires) and weak electricity (such as telephone lines and network cables) are placed in a tube or box, so it is time-saving and labor-saving to lay one less tube. There are hidden dangers: there will be interference when calling the internet. At the same time, if there are too many threads in a pipeline, there is a danger of fire. Standard operation: separate wiring of strong and weak current, and prohibit one tube and one bottom box of strong and weak current.

6. There are no connecting fittings, and the length is not enough. Because the length of the insulating tube is not enough, it is just a bend here. No connection fittings are placed, and a section is exposed at the connection with the junction box. There are hidden dangers: if it stays for a long time, it may lead to leakage due to aging of the line. Standard operation: There should be something connected between the nozzle and the junction box.

7, repeated wiring, a lot of repeated wiring, multi-purpose materials, wasting the owner's financial and material resources. There are hidden dangers: once there is a problem with the line, the layout like "tight encirclement" is difficult to detect. Standardized operation: Carefully arranged, under the condition that the pipeline capacity does not exceed 40%, the lines in the same direction can be threaded in one pipeline. But we must separate strong electricity from weak electricity.

8. Typical barbaric construction, the conduit was damaged by the follow-up project. After the pipeline is laid, the ground is slotted, resulting in the penetration of the laid pipeline. There are hidden dangers in the decoration: after staying in, you may find that one room in your home is out of power, so you can only test all the wires in your home one by one and re-thread them. Standard operation: the place where the pipeline is laid cannot be constructed again. If there is any damage, it is forbidden to connect halfway when changing wires. When the circuit load is heavy, sparks are easily generated at the joints of the wires in the threading pipe, causing fires.

9, putty with cement typical shoddy. On many construction sites, the mistakes made by the construction team are knowingly made, not to mention horizontal slotting. After the conduit wiring is completed, putty powder is used as cement. There are hidden dangers: the transverse slotting during decoration destroyed the bearing capacity of the whole building and reduced the seismic capacity of the original design. Standard operation: the cement used to block the trunking must be in accordance with the cement ratio of the original structure to ensure its strength.

10, the wires are not separated, and all wires use one color, in order to save labor. There are hidden dangers: once there is a problem with the line, the unclear line will be detected again.
