How to make an opening in the bearing wall, how to strengthen the opening with your own hands

Buying an apartment, you do not always get what you see in the ideal. Therefore, many people buying ready-made housing, try to bring it to the cherished dream on their own. Often, to get the housing of the right quality, you have to cut through a new window in the house or make an archway and the most difficult - the opening has to be made in the bearing wall.

Aperture in the bearing wall - only with the permission of the state inspection

It is worth mentioning at once that nothing illegal can not be done, which means that before proceeding to work, it is necessary to approve the future project in special state instances.

And only after you have received permission to create an opening in the bearing wall, you can start working.

Work should go strictly on the project with observance of all technological processes, we will try to prompt, how correctly to cut an aperture for a door in a bearing wall, how to strengthen and strengthen an aperture.

Tools and equipment needed to pierce the opening in the supporting wall

Any work to dismantle a brick or concrete wall involves a huge amount of harmful building dust.

The work itself is very heavy, so it requires a special high-tech tool.

A large volume of construction dust is a heightened hazard for humans. Based on the above, you will have to stock up on the following equipment and tools:

-powerful perforator, type puncher sparky;

- tool for diamond cutting of concrete;

-powerful Bulgarian;

- Welding tools;

hammer, sledge hammer;

- respirator and glasses for working;

-binding;

- Channel of the required size, according to the project.

Preparing the shroud for laying the future channel

With a perforator, along the entire width of the future doorway, it is necessary to cut the shrouds.

Shtroby, preliminary, are not made through, but in accordance with the width or depth of the channel.

When calculating the design, the size of the channel depends on the configuration of the building itself, its floors, the weight of the building structures, etc.

Since on your hands you have a document in which the dimensions of the bearing channel are indicated, you must pierce the shrouds in accordance with the length of this channel.

Shtroby punched on both sides of the bearing wall, while you must make the markings in such a way that the shtroby match with each other on both sides.

In this case, a puncher will come to the rescue.

Punch, better in the corners of the future doorway, holes are drilled through.

Then, focusing on these through holes, the corresponding marking is made from both sides of the wall.

The installation of the channel - the key to strengthening the opening in the supporting wall

Before us is the task of strengthening the load-bearing wall, in which we will make a doorway, installation of channels.

The work is as follows: on both sides of the wall it is necessary to install the cut channels in the cut barbs, then pull these channels through long pins, and the lateral channels can be connected to each other by welding.

Phased work:

- prepare the cuts of the channels to the desired size. As a result, we get pairs of left channels (strengthen the vertical left side of the opening), a pair of right channels (strengthen the vertical right side of the opening), a pair of upper channels (to strengthen the top of the opening), a pair of lower channels (reinforce the bottom of the opening, if this window);

- Using clamps, we compress a pair of (any) channels and make through holes in them, the step between holes along the length of the channel is 30-40 cm. The holes are made in all pairs of channels;

- install the prepared channel in the penetrated holes and make a through hole through the wall and installed a channel for the studs;

- put the side blanks, after installing the pair, through the through holes are installed studs, on both sides of the studs on them put on washers, engravers and screw the nut. With the help of the lever, the nuts tighten;

-After installation of horizontal pairs of channels, above described method, we make installation of vertical horizontal pairs of channels;

- A ready-made structure of channels, using welding, in all accessible places, is strengthened by the use of a firing. So, we created a design from the sections of the channels and qualitatively fixed it.

Expansion of the opening, the technology of operation depends on the material of the bearing wall

Our task is to remove what is inside the metal perimeter.

If the wall is brick, one row of bricks is removed and this will be the most difficult task, and then all other bricks are gradually removed.

If the load-bearing wall consists of concrete with reinforcement - it is necessary to sweat.

Here the Bulgarians and the puncher will be assistants. Professional builders are advised to cut concrete into cubes.

Applying the grinder, a cutout of the wall is made to the full depth, and then a cube is cut with a pitch of 5-8 cm and this cube is pierced by a perforator.

Relatively easy is to dismantle the load-bearing wall inside the room, and dismounting of the outer load-bearing wall, more complicated.

The outer wall is removed for a long time, the work is very dusty, you will have to have patience.

Stage final - we will continue strengthening the opening

Our task is to complete the work to strengthen the metal structure.

The work goes in the next stage:

- with the help of transverse plates are connected by welding the channel from both sides of the walls. The plate should have the following dimensions: a thickness of more than 4 mm, a width of more than 50 mm, it all depends on the design. The plates, as well as the studs, are fixed along the whole perimeter of the opening with a pitch of 30-40 cm;

- the channel is additionally attached in places where the opening is cut (in those places that were closed during the preparatory work);

On the channel metal wire mesh is welded, along the perimeter, the mesh is needed for the production of plastering works of the aperture.

So, after spending a huge amount of work, we got a reliable opening, created the necessary structure without violating the construction regulations.
