Preparation of tools.
First of all, it is worth noting which tools are useful in this matter:
- drill or perforator;
- drill bit for concrete;
- hammer
- pliers or
- pliers directly, self dowel-nail.
First you need to select and prepare tools for work. If you hammer a dowel nail you plan in concrete walls, then it's worth getting a puncher. If you purchase such a device is expensive, you can replace it with an electric drill with a bump function. If the wall is brick, you can confine yourself to a small manual electric drill. In the worst case - you can take a roll. In any case, it is worthwhile to take a special drill bit for concrete with a tap.
Stamped on the shank of the drill, the diameter should correspond to the same stamping on the dowels, and the length of the drill bit with the groove( working part) should be at least 5-6 millimeters larger than the full length of the dowel. It is necessary to have a hammer and a hammer on hand. In the role of the core can come up an old or unnecessary dowel, you can have a larger diameter.
Preparing the seat.
Choose the place to drill with caution, tk.it is worth taking into account a number of points. First, it is necessary to check whether the thickness of the base( any where the dowel-nail will be beating: the ceiling, wall or floor) is enough to ensure that the drill or the dowel itself does not penetrate it. Although this should be taken care of even before the purchase of the dowel, directly at the stage of work planning.
Secondly, the strictest is to check for hidden electrical wiring, becauseIn the wall or on the ceiling, live wires can pass in special grooves or channels. Thirdly, when drilling concrete, it is necessary to take into account the metal reinforcement, which is an integral part of the structure of the concrete partition.
If a drill bit hits the valve, its destruction may occur, and it is even more likely that the drill will fly out of the hand. When drilling brick masonry, it is worth paying attention to the cement plots, because in them the dowel will not normally hold.
Drilling the seat.
Noting the safe place for work, it is worthwhile to heel the concrete, so that the drill does not move away from the intended place at the beginning of drilling operations, the electric drill suffers especially. To do this, it is enough to knock out a shallow hole in the surface of the base with a hammer and a punch.
Place the drill in this hole and start the power tool at the lowest speed. And only after the drill goes deep into at least half a centimeter, you can safely increase the speed of the drill safely. Pay attention: in order that the brick does not burst, you should turn off the bump mode and drill in the usual way.
Shutdown.
That's all. It remains only to hammer a dowel-nail with a hammer, removing concrete or brick dust from the landing hole. Just by hand, install the dowel as deep as possible into the hole and lightly hammer the hammer into the depth you need. If the dowel-nail is damaged or twisted in the process - get it with pliers and take a new one.
