Easy to understand the office of strong and weak electrical wiring construction

Office decoration, Office decoration of the Office electrical wiring Construction is divided into certain points, slotting, wiring, sealing groove, such as four major categories.

First, determine the point

1, the point to determine the basis: according to the office space wiring design drawings, combined with Office work station diagram, with a pencil, ruler or ink points at the location of the cassette label out.

2, Cassette height determination: In addition to special requirements, the height of the cassette and the original strong electric sockets, background music tuning switch height should be the same height as the original strong electric switch. If you have more than one cassette, the distance between the cassettes is at least 10mm.

3, the location of the wiring box to determine:

1) in-line: In the use of weak wiring box size wide, high each increase of 10mm, in depth direction of 10mm reduction.

2 external: According to the type of products used to mark the location of fixed holes.

3> built-in: Determines the height of the pipeline into the product used.

Second, open groove

1, to determine the slotting route, according to the following principles:

1 the shortest route principle;

2) do not destroy the original strong electricity principle;

3 Do not destroy the waterproof principle.

2, determine the width of the slot: according to the number of signal lines to determine the number of PVC tube, and then determine the width of the groove.

3, determine the groove depth: if the choice of 16mm PVC pipe, the slot depth of 20mm, if the use of 20mm PVC pipe, the groove depth of 25mm.

4, Groove appearance requirements: horizontal flat vertical, uniform size.

5, the measurement of the Groove: Cassette and wiring tank independent calculation, all the slots in the beginning of the slot to the end of the groove measurement, if the width of the line slot more than 80mm according to the two-wire slot length calculation.

Third, wiring

1, to determine the smooth line cable:

1) network cable, telephone line test: Do Crystal head, with Network tester test pass break;

2 cable TV Line, audio and video line, Audio Line test: respectively, using a multimeter test pass;

3> Other cables: Use the corresponding professional instrument test break.

2, determine the location of the line length:

1) measure the length of the distribution box trough to each point position;

2 Plus each point and the distribution of the box slot at the redundant line length: The point of exit line length of 200mm-300mm, wiring box: line length of 500mm, background music export: line length 1.5 meters to 2 meters.

3, to determine the label: all types of cable by a certain length of the cut after the end of the line on both sides of the label, and note: weak type-room-serial number.

4, determine the number of lines: Pipe inside the cross-sectional area should not exceed the cross section of the pipe 80%.

Four, sealing trough

1, fixed cassette: In addition to the kitchen, toilet cassette to protruding wall 20mm, other cassettes and wall requirements flush. Several cassettes are required to be on the same horizontal line when together.

2, Fixed PVC pipe:

1 The ground PVC pipe requires a single meter each interval must be fixed;

2) Geosyncline PVC pipe required to be fixed at two meters per interval;

3 The wall Groove PVC pipe requirements must be fixed at each interval of one meter.

3, Sealing Groove: The wall after sealing groove, the ground must not be higher than the plane.

4, cleaning the construction site: After the closure of the trough, removal of garbage, cleaning the construction site.

1 each weak electronic system uses star type structure.

2 line thread pipe 2~3 root from the building distribution box into the computer room, thread pipe from the computer room to various information points, the laying of dark tube (threading pipe) should be used steel pipe or flame-retardant rigid PVC pipe (hard PVC pipe).

3 The pipe diameter utilization rate of linear pipe should be 50%~60%, and the pipe diameter utilization ratio of elbow pipe should be 40%~50%.

4 If there is a local interference source on the line and the minimum net distance is not satisfied, the pipe should be used.

5 If the line of the dark tube is more than 30 meters long, the middle should be installed over the wire box.

6 The dark tube must be bent when laying, its route length should be ≤ 15 meters, and the paragraph shall not have S-bend. If the continuous bending more than 2 times, should be added to the wire box.

7 The dark tube bending radius shall not be less than 6~10 times of the pipe diameter.

8 in the dark tube hole must not have a variety of cable connectors.
