While the construction of indoor home plumbing is generally plumbers to do, but in order to ensure the safety of the subsequent electricity in the wiring slotting this piece of homeowners still need to know some knowledge. Below, we will introduce you to a variety of wire groove practice pictures, wire groove 90 degrees practice step-by-step charts related to content, the need for friends remember to collect this article!

Wire trough various bend practice picture

1, with a hammer to make holes, plastic expansion bolts, break the cover plate by hand, with wood screws to screw the base plate into the expansion bolts, there is no hammer or impact drills, you can use cement nails to nail the base plate directly on the wall, corners and parting of the line of the place can be used in the corner of the corner, corner, tee.

2, in the power supply and the outlet to leave enough wire head after the wire in the baseboard, buckle the cover, discharge wire and buckle the baseboard at the same time, the interface of the baseboard and the interface of the cover should be staggered. Platoon lamp line when the zero line does not pass through the switch, directly connected to the lamp and the power supply, the fire wire must be into the switch, the switch to leave enough wire head.

3, the wire groove is not long enough to need to be connected to the need to intercept the wire groove, the tool can be used with a craftsman's knife, you can also use the diagonal pliers, the base plate and the cover plate at the same time can be intercepted with a hacksaw.

4, according to the design drawings on the direction of the wire line positioning, traditional drawing tools have carpenter's bucket, modern drawing tools have laser scribing instrument, set the distance in a set of laser rangefinder, dark box positioning, the positioning of the open line switches and sockets with a box ruler and pencil.

5, grooving to follow the principle of the shortest route, without destroying the original strong electricity and waterproofing. Construction specifications require horizontal and vertical. Operation is not in accordance with the requirements of the construction, the slot opened like a spider's web, horizontal and vertical, disorganized, especially the emergence of oblique grooves. The consequence is that the wall once opened slot will appear cracks, and the scope of cracks will gradually spread around.

1, first according to the actual size of the elbow side projection drawn. Including the seam line.

2, according to the line of each closed wireframe graphic divided into separate graphics.

3, take a drawing, (will be the center line perpendicular to the setting) drawn on another piece of paper, along the height of the drawing of the two top and bottom parallel horizontal lines, and perpendicular to the center line, the length of exactly the circumference of the diameter of the drawing. (Closed rectangle)

4, the drawing of the vertical direction for equal parts, and marked, and then these equal parts of the vertical line drawn into the unfolding of the rectangle just drawn, pay attention to the unfolding of the map on the point must correspond to the point on the projected drawing.

5, the pattern of diagonal lines along the horizontal direction for equal parts. And parallel to the unfolding of the drawing, and correspond to the corresponding points. Expand the sample to get the intersection of smooth connection, is the unfolding of the curve. The denser the equalization, the more accurate the curve will be.

6, put out the amount of bite, and plate thickness treatment.
