At present, many problems of family decoration after moving in lie in concealed works. Moreover, because the construction of concealed works directly affects the quality of life of owners, it can be said that concealed works play a vital role in the overall construction of family decoration. For example, during construction, the conductor was not sheathed with insulating pipe. After the owner moved in, for some reason, the conductor was damaged, resulting in a short circuit of the conductor, which directly affected the use. But these problems in the engineering test

at present, many problems after family decoration and occupancy are caused by concealed works. Moreover, because the construction of concealed works directly affects the quality of life of owners, it can be said that concealed works play a vital role in the overall construction of family decoration. For example, during construction, the conductor was not sheathed with insulating pipe. After the owner moved in, for some reason, the conductor was damaged, resulting in a short circuit of the conductor, which directly affected the use. However, these problems may not be exposed during project acceptance. Therefore, it is very necessary to emphasize the importance of concealed engineering construction. Here, we uniformly define the installation of wood keel in the waterproof works, power distribution works, plumbing works and wood floor construction in the family decoration project as the construction of concealed works

suggestions for waterproof engineering construction

1. Cleaning preparation: first, clean up the parts ready for waterproof construction, such as the sundries on the wall and ground surface, shovel off the loose parts, and then grind the potholes and uneven places with cement mortar, and then level the whole surface

2. After the cement leveling layer is dry, large-area construction should be carried out in strict accordance with the construction requirements of waterproof materials (see the construction instructions)

3. Make a waterproof layer on the wall of kitchen and toilet, and the construction height of the waterproof layer should not be less than 30 cm. If the wall itself is a light wall, the whole wall must be waterproof

4. The intersection angle between wall and wall and the intersection angle between wall and ground should be cleaned. Use corner wipe or finger to sweep and clean, and should strictly prevent false leakage

5. The junction of the water outlet and the ground should be cleared, and the junction of various through pipes and the ground should be treated according to the above methods

special note: since most of the causes of water leakage in the waterproof layer are from the corners, as long as the corners are handled well, the possibility of leakage is very small

suggestions for the construction of water supply and sewerage works (specifically refers to iron pipes)

1. Galvanized iron pipes must be used for drinking water pipes to prevent secondary pollution of drinking water

2. Hemp wire must be used for sealing of hot water pipe, and tetrafluoro tape can be used for cold water pipe

3. If the connection distance is greater than 1 meter, in principle, the use of hoses should be prohibited

4. It is strictly forbidden to use the hose when it is used to prevent the hose from being damaged and broken

5. When the iron water pipe is connected at 90 degrees, the length of the water pipe threading shall not exceed the diameter of the water pipe

6. The installed water pipe must be fixed (especially the hot water pipe)

special note: when the plumber uses the thread of the threading plate on the water pipe, if the thread is too long, when connecting at 90 degrees, it may cause the flow cross-section to be too small, resulting in too small water outlet of the faucet, affecting future use

suggestions for construction of power distribution engineering

1. Distribute the circuit direction according to the engineering requirements. First, mark the line direction on the wall and ground, determine the installation position of future cassette, and make preparations for slotting

2. On the wall, mark the direction of the wire duct in advance, open the wire duct with appropriate depth (determined according to the diameter of the wire duct and the number of wire ducts), and open the burial groove of the cassette. The wire trough must be horizontal and vertical, with the same depth; The position of cassette requires the same height of similar cassette

3. Lay conduit. Here we should pay attention to: rigid PVC pipes should be used for wall laying; Pipelines laid on the ground shall be water, gas and iron pipes; Pipe joints shall be used for the connection between pipes; 90 degree elbow shall be used for 90 degree corner; Fixing measures must be taken for the conduit; The coaxial cable of TV antenna and telephone line shall be threaded separately, and the distance between adjacent conduits shall be no less than 30 cm; The pipe diameter should ensure that it can be pulled freely after threading

4. Fix the cassette and adjust the position of the cassette

5. Thread the wire into the conduit, and pay attention to reducing the connectors of the power wire as much as possible; No joint is allowed between TV coaxial cable and telephone line; The power wire connector needs to be double insulated with insulating tape and waterproof tape

special note: in home decoration, electricians once walked the lines well, but later they were inadvertently damaged by other personnel. Therefore, in order to ensure that the above situation does not occur, it is best to mark the location of the wiring

suggestions on the construction of floor wooden keel

many companies do not regard the construction of wooden keel as a concealed project. The reason why the author arranges this is to unify the invisible projects after completion

1. In principle, the specification of wood keel shall not be less than 2.5 × 3.5 cm. If conditions permit, wooden keels with larger specifications should be used

2. The spacing of wooden keels should be determined according to the length of the floor, but the supporting keels under each floor should not be less than two, otherwise it will directly affect the stress on the floor and shorten the service life of the floor

3. The wood keel should be fixed by both nailing and gluing methods. The nails should be nailed into the wood keel from both sides at a 45 degree direction. If limited by construction conditions, they must be nailed from top to bottom, and the nail cap must be submerged into the keel

4. The joints of each row of wooden keel must be staggered. It is strictly forbidden to line up the joints of wooden keel, which will affect the overall stress of keel. Due to the problem of the ground, there will be a certain gap between the wooden keel and the ground, and the gap between the wooden keel and the ground must be adjusted with a wooden wedge, and it should be plugged. It is strictly forbidden to use small wooden blocks to plug the pad

5. If the project cost allows, the following methods can also be used to improve the installation level: 1? Leveling the whole ground with cement mortar mainly depends on whether it can be done in the project time. 2? Filling the space between keels with ceramsite or slag can not only fill the space between keels, but also absorb moisture; 3? Before installing the keel, apply waterproof paint on the ground; 4? Before installing the keel, the ground is covered with plastic film, which has the same effect as the third point, but it is rarely used; 5? A layer of high-quality joinery board (commonly known as big core board) is installed on the keel as a rough floor, which can play a role in overall connection and uniform stress. But if we directly use solid wood to make rough floor, the cost will be higher

special tips: the wooden keel after installation and fixation is not allowed to be loose, and the height difference between adjacent keels is not allowed to be greater than 0.5mm. If the above phenomenon occurs, it should be dealt with in time
