1. Construction Procedures for Circuit Renovation Projects The power cords, TV antenna cables, and telephone lines in home renovations should be re-arranged according to the needs of the family's daily life. Therefore, in the renovation project construction, the displacement of various sockets is indispensable. s project. When carrying out various line shift transformations, the position of the line terminal socket shall be determined first, and the exact position and size shall be marked on the wall surface. Then, the method of drawing the lead to the nearest similar socket shall be: if the socket is in the upper part of the wall. , Slotted perpendicularly upwards in the wall, to the top of the wall to install decoration> In the installation line of the decorative corner; If it is in the lower part of the wall, vertically slot down to the bottom of the skirting board. The groove depth is about 15 mm, The wire conductors are placed into the sheath of the sheath, and they are placed in the groove in the wall and cemented with a cement mortar to fix it in the wall. If the original socket is reserved, reinstall it in its original position. If it is not retained, block it with cement mortar after filling it with bricks. The wire along the ground, when installing the skirting board, lies on the inner side of the bottom of the skirting board. The wire along the top corner is concealed inside the decorative corner line when the decoration line is installed.
2. The construction specifications of the circuit renovation project should be consistent in terms of the depth of the trench and the top of the slot line. After the control line is ejected on the wall, the wall surface is cut with a marble machine to manually slot. When installing the circuit, the bushing must be added. The connection of the bushing should be tight and smooth. The corner inside the corner should be cut and the arc-shaped interface on one side of the incision should be cut and installed. After the wire is installed into the casing, the wire fixing clamp should be used. After the wire is fixed in the wall and the wall surface, it is concealed by plastering or concealed by the skirting board and the decorative corner line. The installation of the outlet box shall be preceded by a hole in the wall. After the wire is inserted into the box, the box is placed into the hole and the wire is fixed to the panel and the panel is fixed on the box. The method of installing the power switch is the same as that of the outlet box.
3, circuit modification engineering acceptance circuit transformation location, socket model, wire diameter should meet the design requirements. Wires should be added to the wire during construction and installation. It is forbidden to conceal the wires directly in the gray layer. The switches and sockets must be installed securely, in the correct position, with a positive panel, a clean surface and close to the wall. When installing, it should be connected according to the provisions of “Fire Line Into Switch, Neutral Line Into Lamp†and “Left Zero Right Fire, Grounded On Topâ€, requiring flexible and effective switching and smooth and effective socket.
4. Common quality problems and remedies for circuit reconstruction projects The common quality problems in circuit reconstruction are mainly the defects of sparks and failures caused by unqualified materials and electrical products. The solution to this type of problem is to replace the qualified product. Otherwise, if quality problems do not occur at that time, it will take a long time to produce quality problems. In particular, electrical products require higher safety in use, so they must be qualified. The product. The common quality problems in the circuit installation include the malfunction of the switch due to a wiring error, the lack of electricity in the outlet, and the improper installation of the panel. The main reasons for this are incorrect wiring, improper wiring, unstable panel installation, and unscrewed screws. You can cut off the power supply and reconnect the wiring. When installing the panel, close the panel to the wall and tighten the screws. Circuit modification and installation must be performed by professional and technical workers, and must not be blindly tampered with.
5. Estimated duration of the circuit reconstruction project The duration of the circuit reconstruction varies according to the structure. Taking the brick-concrete structure as an example, each worker can manually do the slotting to complete about 20 meters per day. If it is a concrete structure, each person can complete it every day. About 10 meters, all circuit reconstruction projects should be completed in about 4 days to ensure that the entire project duration is completed on time.
