Many who begin repairs in the apartment, take a decision on redevelopment.Such a method would allow a rational use of the territory of his apartment.Often, however, it affects the remodeling and load-bearing walls.How to be in this situation?Is it possible to demolish the bearing wall?Or is it possible to make an opening in the bearing wall?We consider the features of load-bearing walls, as well as cases where they can make an opening.
it allowed the demolition of a bearing wall?
stability is achieved thanks to the house bearing walls, which are made of heavy-duty material.If one of the walls to be removed, the strength of the whole structure will be threatened.Due to the demolition of the wall will be broken engineering calculations.Conclusion: The bearing wall removed completely impossible, it is fraught with trouble
thing is that the supporting wall is subjected to heavy loads.Therefore, because how strong it will be, it depends on the life of the whole house.
Some take a wrong position on this issue.They make a hole in the wall, and then upon appeal to authorities about what they say, do not know or have forgotten to turn.But such people should be aware of the following.According to the latest regulations, unauthorized production of the opening in the bearing wall can result in heavy fines, and in the worst case, deprivation of rights to stay in this apartment.But this is the maximum that you can run.At least in this case to restore the force wall.Even if you managed to hide the fact of redevelopment, sooner or later, they will know about it.
So, to get the coveted permission, you will need to gather the following documentation:
- floor plan of the apartment.
- sketch redevelopment.
- Certificate of ownership of the apartment.
- completed application in a strictly prescribed form.
If you still got permission, you can start to work.
opening manufacturing methods and tools necessary
With regard to the manufacture of the opening, many think about the pneumatic drill.But this belief is mistaken.Although this method is time-tested, not in all cases, it is effective.Furthermore, using a jackhammer for making the opening in the bearing wall has a number of drawbacks:
- appears a large number of microcracks.
- violated the integrity of the wall, especially if it is made of bricks.
- Manufactured opening must be further processed, which would entail additional costs.
- In the process, there is a lot of noise and dust (secretly certainly not to do).
- Many walls have metal fittings, making it difficult to work.
Today, there are a number of advanced technologies that allow you to quickly and with minimal labor costs to make an opening in the bearing wall.
- use of cable equipment.In this case, using special bushing and rope, which established artificial diamonds.This method is effective for the reason that when it is used does not produce dust, vibration, noise.
- Diamond.There are special drills with diamond coating.They can drill straight holes around the contour of the opening.Accordingly, this method will save your costs for the subsequent processing of the walls.The use of diamond drilling allows you to save the integrity of the wall as brick and reinforced concrete.
- saws with diamond-coated.The best way if you want to find the best option in the manufacture of the supporting wall of the opening.There are two methods of cutting: Stationary and hand.The choice will depend on the size of the aperture and the required quality.Breaking
First we need to implement a series of preparatory processes.Prefabricated bridge, which will take over all the main burden from the upstream wall of the array.This element is very important: on the strength of his will directly depend on the security of the entire structure and yours, respectively.In this case, consider the following:
- wall thickness,
- ratio of the size of the walls and openings,
- technical condition of the walls,
- material from which made the walls,
- distance to adjacent walls and ceiling,
- location slabs,
- number of floors above your apartment.
As for the material for the bridge, the ideal option would be steel.It is the most reliable and sturdy material for this purpose.Usually, you can purchase channel, which connects the bolts on both sides, or I-beams.If you chose to install channels, is suitable for its connection bolts M20.The distance between them should be two feet.The length of the bridge should be enough to keep it bent under the heavy loads.
Now proceed to the manufacture of the opening.To begin with plaster removed from the wall.To do this, you can draw the outline of the pre-opening chalk.Then Grooves opening for mounting a jumper.These Grooves are doing on both sides.Next, drill holes for mounting bolts jumpers.These niches should be well cleaned, so that they can be easily set channel.It should eliminate dust, moisten with water wall.
After making cutting grooves Prepare mortar cement M500.The solution should be thick and dense.It should be put in Stroebe made, and after, and set the channel to pull bolts.Now, the entire structure must be properly harden.
In the process, the voids can be formed.How to fix them?This can take small block pieces / bricks, which are installed on the same solution.
You can then proceed directly to punched openings.It is possible to use any of the above methods.It should be noted that the penetration of the opening must be performed gradually.Think about how you will remove the resulting dust, and the size must be waste.
After making the opening, should implement finishing slopes.In some cases it is possible to produce structural reinforcement, particularly if the opening has a greater thickness.To do this, the corners mounted metal corner that can be welded to the bulkhead.These corners are also welded together by metal plates.It remains a plaster soffits and proceed to finishing.
There is another method of manufacture of reinforced concrete beam bridge.By its strength, it is not inferior to the above-described technology.To install it should be done through pre-opening the entire length of the concrete beams.It, in turn, is placed on the cement.Punching the aperture can only be when a cement beam grabbed.The subsequent process is similar to that described above.
If you want to use non-standard solutions for interior design with the redevelopment of the premises can be made arched doorway in the wall carrier.But in this case it needs to make a special design.For producing such openings necessary to prepare a profile or other material that will repeat exactly the outline of the opening.Fixing is carried out on the same principle.The only difference is that the design as beams bolted together should not only among themselves but also with the wall.
before punching an opening in the bearing wall, weigh the pros and cons.Remember that you must first obtain a permit.
