Construction process of strong and weak current wiring in office

This paper will introduce the construction process of office strong and weak current wiring, including fixed point, slotting, wiring, slot sealing and backfilling.

Point determination

According to the layout design of the office space, combined with the schematic diagram of the office station, mark the position of the cassette at each point with a pencil, ruler or Mo Dou. Except for special requirements, the height of the cassette is the same as that of the original high-voltage socket, and the height of the background music tuning switch should be the same as that of the original high-voltage switch. If there are multiple cassettes, the distance between cassettes should be at least10 mm.

grade

The slotting route is determined according to the following principles: 1 > the shortest route principle; 2 > it does not destroy the original high-pressure principle; 3 > Don't destroy the waterproof principle. Determine the slot width: determine the number of PVC pipes according to the number of signal lines, and then determine the slot width. Determine the grooving depth: if 16mm PVC pipe is selected, the grooving depth is 20mm；; If 20mm PVC pipe is selected, the grooving depth is 25mm.

wiring

Make sure the cables are unobstructed, determine the length of wires used at each point, and determine the labels: cut all kinds of cables according to a certain length, and put labels on both ends of the wires respectively, indicating: weak current type-room-number. The cross-sectional area of the lines in the pipeline shall not exceed 80% of the cross-sectional area of the pipeline.

Sealing and backfilling

Fixed cassette: Except for the cassette in the kitchen and bathroom, which should protrude 20mm from the wall, other cassettes should be flush with the wall. When several boxes are together, they are required to be on the same level. Fix PVC pipe and seal the groove: the wall and ground after sealing the groove shall not be higher than the plane. Clean up the construction site: after sealing the groove, remove the garbage and clean up the construction site.
