The opening in the bearing wall - is it worth the risk?

The opening in the bearing wall - how to avoid mistakes when cutting?

If your plans include the opening device in the bearing wall, you need to take care of all the work carried out by professionals with experience and proper "arsenal" of tools.This condition is important for the reason that the supporting wall is one of the main elements of the skeleton of the building.

not too skilled workers and the use of inappropriate tools - all this can significantly degrade the stability of the building.Blunders, for example, failure to work the technology could even lead to its collapse.Cutting openings in bearing wall should be carried out on the basis and in accordance with the pre-prepared project of redevelopment of premises!Today, to make an opening in the wall, you can use the following tools:

• handmade diamond cutter.It is a professional tool for cutting walls whose thickness does not exceed 30 cm. The device for opening works are carried out on both sides of the wall.
• wall saws - Technical installation, allowing to carry out deep cuts up to 70 cm The works can be carried out even if the wall thickness is greater than 1 meter..However, the machine is rarely used in residential premises in connection with the operation difficulties.

Practice has shown that it is a special equipment and diamond tools let you make all the work as quickly and safely.Just before starting work you need to install the rack-jacks, the main purpose of which is to transfer the load bearing wall.

Depending on the load-bearing wall thickness of the cutting can be carried out in whole or in parts.The first embodiment is well suited for walls of prefabricated houses, since their thickness is small - about 15-18 cm Second Embodiment is most common in monolithic houses where the walls are somewhat thicker -.. 20-22 cm, if necessary perform a hole in the wall technical diamond drilling technology used.

Strengthening the opening in the bearing wall with the sill

Cut a doorway in the wall carrier is difficult, but possible, but this is only the first stage of works.After cutting the need to strengthen the support element of the building, because after the removal of the wall load has increased significantly.We should not forget the pre-executed redevelopment project.That it should be a calculation of load changes on the support element of a residential building, taking into account the number of storeys, works and construction materials.Make opening helps strengthen the special jumper in the upper part - channel.

Obviously, this jumper must be strong enough to withstand the load not only from the rest of the load-bearing wall, but relying on his ceiling. That's why experts recommend to stop your choice on steel products.Steel bridge, used to enhance the hole made is a two channel, joined together with bolts.For their installation above the opening on both sides of the wall runs shtrobirovanie recess depth of half a brick.Each Stroebe in a prepared solution of "recessed" steel channel.Then both sill bolted.

Enhance this construction permit-welding metal plates to the bridge.

When installing the jumper above the doorway is necessary to observe the distance between the connecting elements - it should not exceed 50 cm, otherwise suffer structural strength and load bearing wall could collapse..Channels on both sides have come to the supporting wall about 15-30 cm, and used for their connection bolts may not have a diameter less than 20 mm.All of these values ​​should also be reflected in the draft redevelopment!

door or arch in the bearing wall - to be or not to be?

Of course, the process of doing all the work of cutting and the strengthening of the opening - this is important, but all this can not be.How so?Very simple!Do not let the "law", or rather, will not approve your project re-planning by the relevant state bodies and municipal officials.In addition to the project itself, in which everything must be clearly set out, you have to collect a lot of documents and run them on housing inspections and almighty BTI.

Among these documents include a contract with professional builders, who will perform this type of work.Builders, in turn, must be members of self-regulatory organization (legal innovation), which should also be documented.Everything else you need to get hold of a floor plan of the structure and prepare the documents of title to housing.Solid, is not it?

Another surprise will need to find the "author" of the project of the house, which will be the device or the expansion of the opening in the bearing wall.Typically, this time is ignored when the changes are minor.However, when it comes to load-bearing structures, it can not do without a designer home.

Of course, you can make unauthorized alterations, which can show up at any moment and bring you to court, fines and obligations to restore the original appearance of property.In rare cases alterations affecting the load-bearing structures, it is possible to legitimize after execution.Experts do not recommend to rely on the traditional "maybe", it is better to agree on all the changes in advance.
