(1) all types of switches: specifications must meet the design requirements, and product certification.
(2) all types of sockets, specifications and models must meet the design requirements, and product certification.
(3) plastic (table) board: should have sufficient strength. Plastic (table) board should be flat, no bending and warping deformation and other phenomena, and there is a product certification.
(4) wooden (table) board: its thickness should be consistent with the design requirements and construction acceptance specification. The board should be flat, no splitting and bending deformation phenomenon, paint layer intact without peeling.
(5) other materials: metal expansion bolts, plastic expansion tubes, galvanized wood screws, galvanized machine screws, wood bricks and so on.
2, the main machine tools:
(1) red pencil, tape measure, level, wire drop, insulated gloves, tool bag, high stool, etc..
(2) hand hammer, burin, wire strippers, sharp-nosed pliers, tie awl, tap, casing, drill, hammer, drill, nail gun, etc..
3, operating conditions
(1) a variety of pipelines, boxes have been laid. Box closing leveling.
(2) The line conductor has been worn, and has been done insulation shaking test.
(3) Internal decoration work such as slurry work, painting and wallpaper on the walls have been completed.
2, switch and socket installation order
1, first in the drawings to find the specific location of the switch and socket in the plan looks a bit like the English "F".
2, with a pre-prepared socket box frame to draw a rough frame, this tool is very helpful to locate the neat.
3, measure the distance from the wall edge of the alignment of the wire conduit in the vertical direction.
4, Measure the same width at the corner of the wall.
5, according to the location of the points just measured can be drawn with a bullet line two vertical lines.
6, the cutter along the bullet line to cut.
7, drill out, open the appropriate pipe groove, the depth of the groove to match the diameter of the pipe, the pipe to the right number, and open whether neatly respond to the level and experience of a construction team.
8, a line box hole open, and embedded from the box outward a connector.
9, done the wire box, embedded in the open wall.
10, calculate the distance of the pipe from the wire box to the ground, to ensure that the bend is smooth and the pipe does not break.
11, the pipe and wire box is connected, the bend just smooth shelf on the ground.
12, new tubing threading can not be used to the wire, but if it is wearing valuable audio line or long distance threading more standardized practices will be used to the wire.
13, the first end of the steel wire to make a hook, to prevent the tip of the pipe to scratch the internal.
14, the wire slowly inserted into the pipe, slowly push, to avoid too fast and lead to scratching of the internal pipe.
15, the wire from the other end out, and the wire screwed together, slowly pull the wire into the pipe, the wire is actually the lead in the process.
16, after the wire to the wire box, the tubing is connected to each other with matching connectors.
17, as a hidden project, the interface link must be closed, unbroken.
18, the other end of the wire should be promptly protected with crimp caps.
19, the wire part of the standard practice is all hidden into the wire box, but the control of the length of the wire is a detail problem, no more no less is considered standardized.
20, threading partially completed, after measuring whether the circuit is smooth and a series of acceptance before filling with cement leveling.
21, ceiling wire threading process is also basically so, just generally due to the ceiling is more light line, so only need to wear red fire wire and blue zero line.
3, switch and socket installation skills
1, switch and socket can not be installed in the tile tile pieces and waistline.
2, switch socket bottom box in the tile hole, the border can not be larger than the bottom box more than 2mm, also can not open into a round hole. In order to ensure that the future installation of switches and sockets, the bottom box edge should try to level with the tile, so that the future installation will not need to find another longer screws.
3, the location of the installation of switches and sockets can not have more than two tiles are destroyed, and try to make it installed in the middle of the tile.
4, installed faucet must be opened at the hole into a round hole, can not be opened into a square hole, and can not be opened into a "U" type, and then in the "U" type hole in the patch, the size of the hole can not be more than the diameter of the pipe more than 2mm, and the spout side must be with the tile Flush.
5, socket installation, open socket from the ground should not be less than 1.8 meters.
6, concealed socket from the ground is not less than 0.3 meters, in order to prevent children from electrocution, touching with fingers or metal objects stabbing the power supply eyelets, be sure to choose a safety socket with an insurance stopper.
7, single-phase two-eye socket construction wiring requirements are: when the eyelets are arranged horizontally for the "left-zero right fire", vertically arranged for the "fire under the zero".
8, single-phase three-eye socket wiring requirements are: the top of the grounding eyelets must be connected to the grounding wire firmly, solid, connected to the right, never not connected, the remaining two eyelets according to the "left-zero, right-fire" rule wiring, it is worth noting that the zero line and the protection of the ground wire can not be misconnected or connected to the one.
9, refrigerator should use an independent, with a protective grounding three-eye socket. It is strictly prohibited to make their own grounding line connected to the gas pipeline to avoid serious fire accidents; in order to ensure the absolute safety of the family, the hood socket should also use three-eye socket, grounding hole protection can never be taken lightly.
10, the bathroom is often used to bathe in the shower, easy to humidity, should not be installed ordinary type socket, to be selected with waterproof type switch to ensure personal safety.
11, the installation of switches, concealed switch requirements from the ground 1.2 meters - 1.4 meters, from the door frame horizontal distance of 150 mm - 200 mm.
4, how to supervise the installation of switches and sockets
Switches and sockets installation of the supervision of the work of the first to pay attention to the quality of the decoration workers to select the switches and sockets, followed by the supervision of the decoration workers to renovate the process of whether to cut corners.
The following are the quality requirements for the installation of switches and sockets:
1, to ensure that the project
The socket connected to the protective grounding wire measures and the phase line and the neutral line of the connecting wire position must be in line with the relevant provisions of the construction acceptance specification.
The leakage switch used in the socket should be sensitive and reliable.
Inspection method: observation and inspection and check the installation records.
2, the basic project:
(1) switches and sockets are installed in the correct position. The box is clean and free of debris, the surface is clean and not deformed, and the cover plate is tight to the surface of the building.
(2) The switch cuts off the phase wires. The wire into the appliance is well insulated and does not hurt the core. The grounding wire of the socket is laid separately.
Inspection method: observation and power-on inspection
3, allowable deviation items
(1) Ming switch, socket base plate and concealed switch, socket panel installed side by side.
(2) The height difference of the socket is allowed to be 0.5mm.
(3) The height difference of the same place is 5mm.
(4) The vertical deviation of the panel is allowed to be 0.5mm.
Inspection method: Hanging line, ruler inspection.
