Smart home interior wiring slotted technical requirements and processes

1. Slotting technical requirements

1) Determine the slotting route The following principles should be followed in determining the slotting route:

(1) The shortest route principle.

(2) Do not destroy the principle of the original wire tube.

(3) Do not break the waterproof principle.

2) Determine the slot width Determine the type, size, and number of PVC conduits according to the number of wires and specifications, and then determine the width of the slot.

3) Determine the slot depth If a 16mm PVC conduit is selected, the slot depth is 20mm; if a 20mm PVC conduit is used, the slot depth is 25mm.

4) Trunking measurement and appearance requirements

(1) Slot measurement. The slot of the cassette is calculated independently, so the slot is measured from the beginning of the slot to the end of the slot. If the width of the slot is two wire tubes, then the slot should be doubled.

(2) Requirements for appearance of trunking. The appearance of the trough requires horizontal and vertical appearance and uniform size.

2. Slotting tools and processes

1) Slotting tools and equipment ready-to-use tools: hand hammer, tip tweezers, flat tweezers, hammer, cutting machine, excavator, ink fountain, tape measure, level ruler, half-pipe, pencil, gray shovel, ash bucket, Buckets, gloves, dust covers, hoods, garbage bags, etc.

2) Slotting process

(1) Lines. First of all, according to the location of electrical appliances and control appliances for line positioning.

(2) Slotting.

Chisel can be chiseled directly, cutting machine, excavator, and hammer can also be used. Cutting with a cutting machine, slotting machine to the corresponding depth, and then using a hammer or hammer to cut to the corresponding depth, allowing the edge to cut hair. Groove depth should be the same, the general groove depth is PVC wire diameter plus 10mm.

(3) clean up. After confirming that the slot has been opened, it should be cleaned in time, and water and dust should be sprayed during cleaning.

3) Slotting specification process

(1) According to the orientation and the line direction, after cutting the line, use the cutting machine to cut along the elastic line on both sides. The depth of the groove should match the diameter of the pipe, and the horizontal slot must not be opened because it will affect the bearing capacity of the wall.

(2) When the slot is made, try to avoid the wall surface that affects the side of the slot so as to avoid emptying and leave hidden troubles.

(3) The mortar layer and brick corners are cut along the strike line to form the wire trough. To avoid cracking, it is advisable to use multiple inclined cuts and deepening. When the concrete structure is slotted, the depth of the slotting is the standard that can be embedded PVC pipe and the depth is not too deep, so as not to cut off the structural layer of steel and damage the strength of the structural layer.

(4) 90 at slotting. Corners should be cut off inside the corners for the laying of wires and pipes.

(5) Keep the width of the slot as uniform as possible, and connect the arc at the corner.

(6) In the bottom of the tank, drill with a percussive drill to knock in the wooden crucible to fix the wire tube. The wood part should be flush with the bottom of the tank.

The slotting of small gauges is usually done without using a cutting machine (even without using a bobbin), and the slot is directly chiseled on the wall. This will cause the wall surface of the slot to loosen and empty, which will result in the damage of the slot surface. Large, increase the difficulty of sealing. When grooving a concrete wall (shear wall), irrespective of depth will have an effect on the strength of the structural layer.
