Floor coverings / | Adjustable floor. Technology and installation of controlled floors. |
The dream of every newcomer - that repairs were made with high quality, fast and as far as possible without the mud. It applies it to such a labor-intensive process as Flooring. This is such an important stage of repair, which does not wave away from him. The traditional method of laying floor is used for many years and proved its worth. But there are new technologies that carry its advantages. One of them is called " adjustable floor ".
To make it clearer that different " adjustable floor ", briefly acquainted with traditional styling. Usually done first concrete screed, then, as it requires additional alignment, using " Vetonit " or any other self-leveling composition. Then attached plywood, and have at it - a floor covering. When building a cottage or country house, the floor joists are often made on the - dry planed wooden bars. These logs are placed directly on the concrete base, and usually does not attach, and align them with various chips, bricks, planks. Then, on the joists plank rough floor, usually of low quality boards, but it is already finishing.
Technology controlled floor , as follows from its very name suggests, allows you to adjust the height of individual sections of the floor and thus give them the perfect evenness. There are two varieties: the floors on adjustable lag and floors on adjustable plywood.
Adjustable beam floor are used in country houses, as well as the repair of old houses when dismantling the old floor when the level drops and you must return to the original. Doing this with the help of concrete is too expensive, and sometimes impossible, because the house can not withstand such loads. And then on the existing solid foundation laid floor joists, standing bolt-on at a distance of no more than 60 cm apart. Each lag nasverleny holes into which threaded bolts are screwed plastic-rack. Their number depends on the expected loads. Sami bolts with metal dowels or screws rigidly fixed on the ground. These, then bolts are precisely adjusting elements. Now, if a special key to rotate the bolts, lags will rise or fall - which is what we needed. Task Master - Align all on a level and then lay a plywood floor boards or other cover.
The floors on adjustable plywood. If you do not want or can not high enough raise the floor, you can use other technology to use design for adjustable plywood. To her resorted when the apartment is purchased in the new building, or in a flat low ceilings. In this case, the logs are not applied, are used instead bush with internal thread, which is inserted into a pre nasverlennye holes in the plywood. The very water-resistant plywood, its thickness - 12 mm and dimensions - 1,5 x 1,5 m. In this list are inserted into sleeves thread, and it turns out that the plywood as it stands on legs. Each leg is rigidly fixed to the concrete base plugs. On top of sleeve screwed plastic adjustment screws (items 6-7). Rotating the bolts, thereby adjusting the height of the plywood can achieve absolutely flat, horizontal surface. After alignment of the first layer of plywood on it for rigidity plank and softwood attached second layer, overlapped to avoid seams. Now you can lay the floor. The height of its rise above the base amount to no more than 3 cm.
Working together with the materials, considering the double layer plywood is approximately $ 20 per 1 sq.m. It is more expensive than conventional wood floor on joists by about a third, but offset by the rising cost of quality: obtain perfectly flat floor surface. In the traditional method, by placing different boards, this is almost impossible to achieve.
We must remember that in our older homes do not have flat floors. Not only do these houses originally built " no ", geometry over time they begin to sink, warp - so that even a chair can not put straight. After buying an apartment in a newly hassle no less - they are usually sold at all without finishing, so that " the floor question " arises before the masters in all of its inevitability.
What good is a new technology of controlled floors?
To do without wet processes related to concrete work, which always carry a lot of debris and dirt. The speed of the process: plank floor for 1-2 days. For comparison, concrete screed should settle at least 28 days for a full pull moisture.
The design is very easy, which is especially important in older homes, where you can not increase the burden on the overlap. There may be questions the reliability thread, but be aware that the bolts and bushings are made not from a simple plastic, and of highly durable. Suffice it to say that according to various experts, such floors can withstand 3 to 5 tons per 1 square meter.
The new technology of controlled floors, despite his youth, is included in the building construction norms and is widely used not only in villas and apartments, but also in schools, hotels, gyms and even at industrial sites.
Durability controlled floor, according to experts, is not less than 50 years. Because the logs are not in contact with the ground, the floor is well ventilated. For the same reason lags do not rot - and the floor is longer. Even if under it gets wet, it is freely evaporate. Floor covering is securely protected from leaks and flooding by that in two-layer plywood base no cracks. Adjustable floor is much warmer on the floor concrete, because the air layer is formed, and, as you know, there's no better thermal insulator than stagnant air. Provided and additional sound and heat insulation. These are two very important components of luxury housing, and technology allows, if necessary, to strengthen them. For example, when you want to insulate the ground floors in suburban homes with a cold cellar or to protect themselves from too noisy neighbors in a city apartment, between joists are placed on special hooks mats, for example, mineralobazaltovye plate.
Adjustable floor to the same and is much quieter: conventional wood floors eventually begins to crack and go shake and adjustable - no. There is another advantage: the possibility of communication inside floor, and cables and systems can be of any shape and direction.
Good floor - half of repair. Professionals will perform the work quickly, smoothly, nice and free from dirt.
