How to make openings in concrete: the necessary tools, the

Redevelopment of the apartment is more and more often used during repairs. The most difficult stage is the creation of openings in interior and load-bearing walls. Such work can be carried out using various technologies, each of which has both advantages and disadvantages. In the article we will take a closer look at how to make an opening in the concrete wall by yourself.

Nuances of independent work

In this case, it will be about how to cut an opening in the concrete wall with your own hands:

1. Check that the site of the alleged opening of the opening does not pass through utilities or electrical wiring..
2. Draw the parameters of the opening. Its form can be:

• square;
• rectangular;
• ассиметричная.

Arch arch can also be made in the form of a semicircle or a straight line.

Tip: punching openings in structures made of concrete is a difficult task, so if you have never done such things yourself, you'd better use the help of a person who already has experience in carrying out such work.

Incorrect actions can cause cracks in the walls. If they appear on the bearing walls, it can be simply dangerous to be in such a building in the future.

Required Tools

If you are sure that you can make the necessary opening on your own, you should know the list of tools that will be superfluous:

In addition, you need a powerful grinder and channel.

Sequence of work

Below is a guideline for working with a curtain wall:

1. Apply on the future opening marking tape.
2. Punch a hole in the punch on its upper border, half the thickness of the wall.
3. Put a channel in it. At the same time, the latter should go into the hole rather tightly, ideally, if it is necessary to hammer it in neatly there.
4. Scroll to the bottom of the wall. Make a hole in the bottom opposite the first one and also place a channel there. In the latter, make pre-special bolt holes.

Tip: Channels should be installed on the solution, which includes expanding cement.

1. Connect the channels with jumpers.
2. Take the grinder and start cutting the wall on a previously marked contour.

Tip: if you have the opportunity to get to the wall from the opposite side, you can also make a counter file there to facilitate the process.

Consider that diamond circles on the grinder can help you only when the wall is up to 200 mm thick (100 mm on each side). If the wall is thicker, you must use a punch.

1. Knock out the concrete, it is not recommended to allow its complete destruction. Force from channels should be distributed over the entire opening area.

How to make an opening in the bearing concrete wall

The process has three consecutive stages:

1. Cutting the wall.
2. Strengthening the resulting opening.
3. Coordination of openings in the bearing wall.

Let's take a look at these stages in more detail.

Technology

During the first stage, diamond drilling of holes in concrete and diamond cutting is performed. These operations are the most modern in the technology of working with structures made of concrete. The price of a quality tool in this case can not be low.

Advice: it is better to entrust such tasks to highly professional specialists, who will be able to perform them in compliance with the parameters specified in the specification to the millimeter.

Using a diamond disc allows you to avoid cracks and chips on the surface of the wall. As a result, the cuts have a smooth surface, which greatly simplifies their further processing.

In addition, this type of drilling openings in concrete does not leave behind a large amount of dust and waste. Also, cutting of reinforced concrete with diamond circles does not produce harsh and loud noises, and the walls are not exposed to rough blows.

It can also be used to process:

• bricks;
• granite;
• ceramic tiles;
• marble.

You can work without problems in inconvenient places - very close to the floor or ceiling.

Tip: if you need to cut an opening in a concrete wall with perfectly even and straight sides - you just have to turn to professionals who will do all the work as quickly and efficiently as possible.

Stenorezny cars by this method can work equally effectively both in horizontal, and in the vertical plane. Since perfect precision is achieved during the work, smooth openings in the concrete wall are obtained at the exit, which do not require additional efforts for finishing.

Reinforcement

During such work, it is always necessary to ensure the safest operation of the building in the future. For this purpose, the reinforcement of the opening in the bearing walls is used, helping them to retain their basic ability. If it loses it, the overall structure will become weaker, and this may cause an emergency.

As an amplifier, metal structures are used that are mounted directly into the opening. For such purposes, the channel or the corner is most effective. The first option is used most often and is quite economical. Its essence is as follows - an aluminum or steel frame, having a U-shaped cross section, is attached to the opening.

Reinforcement of the corner with a corner is, in fact, very similar to channel, however, it is more reliable:

1. Along the edges should be installed metal corners. At the same time they can be installed overlap or flush with the wall.
2. Then it is necessary to install support legs, which will continue to take the entire main load.
3. Racks must then be pulled off with studs or by welding.

Coordination of openings in bearing walls

According to the law, before creating an opening in the wall that performs a carrier function, it is necessary to create a detailed design of the work, as well as subsequent coordination in certain instances.

As is known, the safety of the building itself and, accordingly, of the people living in it depends on their condition. Therefore, permission for such a project is not always given, for this it is necessary to work it out carefully and prove that the opening will not cause any harm to the supporting wall.

Conclusion

From the article it became clear that the fastest and most profitable option is to use diamond circles and crowns in work. This will allow to perform work without dust and noise, in the shortest time and with the desired result. The video in this article will help you find additional information on this topic.
