When we decorate the house, we should not destroy the load-bearing wall, but we should also be careful not to hit the steel bar when punching holes in the wall. How can we avoid steel bars? Today, Bian Xiao will teach you several methods.
First, how to avoid reinforcement.
1. Before drilling, look at the structural diagram of the house and know the location of the steel bar.
2. Prepare a lighting lamp, and always look at the hole when punching to see if there are any steel bars. If there are steel bars, it is necessary to re-punch them in another place.
3. Draw the position of each hole on the wall first, except for steel bars, water pipes and electric conduits.
4. If you accidentally touch the steel bar, you can re-punch the hole along the direction where the steel bar is inclined at 45 degrees. The angle should not be up or down, nor should it be left or right.
5. When punching holes, choose beams supported by walls.
6. When punching holes in the beam, you should make small holes instead of big ones.
7. This hole should be drilled at the top of the beam, because the stress at the top is very small. Don't drill holes at the bottom of the beam.
8. There is a main steel bar 3 cm below the beam and column. Never hit the main reinforcement. You can't punch holes at 20 cm above the beam and column, and you can't punch holes at 5 cm below.
Second, the wall drilling matters needing attention
1. When selecting an electric drill, the drill bit should be tapered and a drill sleeve should be prepared to fix the drill bit.
2. Before drilling, keep your hands steady and don't shake from side to side. Keep the electric drill vertical to the wall, and hold the electric drill with both hands.
3. When selecting screws, the screws should not be too small. If it is too small, it will fall directly into the hole, and it will not be fixed.
4. If there is resistance when drilling, to reduce the speed, first check whether the core of the drill bit is broken.
5, drilling, should be inserted before and after, in order to prevent the wall powder stuck on the drill.
6. Don't touch the water on the drill bit, it is easy to stick the wall powder on the drill bit, which will only increase the difficulty of drilling.
The above is what Bian Xiao should pay attention to when punching holes in the wall. In a word, you must find a professional master to punch holes in your home. If you don't drill holes yourself, don't drill holes at will. If you accidentally touch steel bars or water and electricity pipelines, the consequences will be very serious. We should know more about the decoration, which will help everyone and avoid damaging the structure of the house.
