How to make a foundation for bannuyu oven

In Russia, the word "bath" appear, according to most historians, but in the eleventh century. Primordially Russian names baths - mov, Vlaznev, mygnya. Vlaznev - a dugout, a small building or something that has an input. The concept of the bath and washed and preserved in the modern language. However, today they are not connected with the ferry. Unlike the names of these ancient word "bath" is borrowed from Latin, the word baineurr (meaning skinny) formed the basis of such a concept as "wellness" (water therapy). The word "sauna" is present in many Slavic languages ​​(Slovenian, Bulgarian, Polish, Serbo-Croatian). Besides swimming, it also meant before the dome ( "church with a bath" - a "church with the acquis"). For bath furnace as necessary and for the furnace - the foundation.

Interestingly, in the old days in the Russian sauna hut placed directly on the floor - it reinforces gender beam or pawned another auxiliary one. But today bath furnace without foundation - this is nonsense, because the savings for builders sexual steel beams directly embed the first crown, and the previous furnace installation method has almost no fits. Fundam under bannuyu furnace is necessary not only for the stability - that it will protect it from the fire, breaking or cracking. However, for each oven - a separate foundation and its specific requirements to it well and understand what will help you to our special article.

Neutral bannuyu foundation under the stove is made of rubble or cement-based concrete, thus it is necessary to refer to more than 10 throughout the area occupied by the stove completely on all sides. Its height should be completely the same as the height of the basement and proper bath. A top of already completely finished waterproofing of grounds laid out roofing felt, or two layers of roofing felt, which put dry bricks and made of metal corners issues to build a special fire cutting.

The ideal foundation for future stoves should be designed in advance and implemented at the stage of filling in all the common foundation

There is also some taboos in the foundation construction of a furnace: it is impossible, for example, dobetonirovat on a pre-laid ground, since there will necessarily irreparable differential settlement oven.

Therefore, the foundation for the furnace in the bath together with the foundation of the pair are not bound, however, if they are both, for whatever reasons, are in close proximity, between the need to arrange a special sand backfill approximately two feet thick.

whether the foundation is required under the stove and what parameters?

Dimensions of furnace bases are more dependent on the soil characteristics and the weight of the unit: for example, fresh oven will weigh about eight tonnes, and in the dry state - less than half. Often independent foundation and formed by radical chimney, due to which the furnace differential shrinkage occurs.

But how deep foundation for the furnace to be laid depends on many factors: the strength and heaving soils, its depth freezing, ground water level, the total depth of the foundation pair, as well as whether the bath itself is finished at the time of construction. For example, such a foundation must be done approximately 80 cm on dry and sandy soils depth, well in heaving - below the so-called freezing depth, i.e. 1.5 m, and not exactly less.

Calculate the exact weight brickwork can be according to the following special formula:

P = 1350 x V,

where V - total masonry (measured in meters).

The construction of the foundation for high-grade metal fuser

It should be noted that the foundation for the furnace is needed, even when the one - from the small ultra-light steel, and was bought by well-known brand in a special home improvement store. Because if it would be a little skewed when working, even if it is almost invisible to the eye, then none of this good will come out at all.

Thus, a furnace of steel sheet, which weighs no more than 150 kg, the foundation must do the following:

• Step One. It is necessary to dig a trench and fill it with gravel well, and then thoroughly compacted. Already compacted active layer should not be less than the 30 cm.
• Step Two. On hard-packed gravel must be filled with a solution of ordinary cement medium consistency and leave it all as a day - to stiffened. Ratio approximately as follows: part of cement, the four parts of sand and water on the eye. This - the so-called foundation sole.
• Step three. The well-dried cement should put a few pieces of roofing material for high-grade waterproofing.
• Step Four. Now the trench to be filled with concrete, which is made in such a proportion: part cement, four - gravel, and 2.5 parts of sand and little water.
• Step five. After this work you need to check the level of a horizontal base made by the foundation.

How to make a foundation under the brick oven

But if the brick masonry is planned heavy metal instead of the design, and the foundation for the oven with his own hands to do must also be substantial:

• Step One. You need to dig a trench to a depth just below the freezing ground and a width of about 10 cm wider than the foundation - it is necessary to exclude the effects of different soil movements.
• Step Two. At the bottom of the excavation necessary to pour sand into 15 cm thick and fill it with water. When the water will come down, you need to fill up the sand again to the required level, then all is filled with water again. When moisture descend again to the bottom to be put broken brick or stone - 20 cm layer. Next, it's all good and well compacted, covered with sand, and again filled with water - this procedure should be repeated as long as rolled in the sand no longer settle.
• Step three. Now it is necessary to pour a layer of gravel about 10 cm, well within the ram and do excavation formwork - that between it and all sides of the foundation exactly left about 10 cm distance, well within the formwork should be placed special reinforced frame.
• Step Four. The formwork must be put concrete truth in such a way that its height was not less than 15 cm, than the surface of the earth. Once all the concrete dries, the shuttering is completely dismantled, well, on the sides smeared with a special tar melted in a couple of layers.
• Step five. In the created free space is necessary to fill small gravel and coarse sand.

Reinforced concrete slab with a pile supports

Another modern method of arrangement of a full foundation under the stove in the bath - it construction of a reinforced concrete slab. The thickness of such plates may vary up to about 20 cm. It is installed either in the bar or on the pile support completely dependent on what the depth of freezing ground.

However, no matter how it is to design a foundation under the bath furnace may be, he must be absolutely sure independent of the main foundation of a bath - to the latter it has no sediment exposure. Then the furnace is sure to be please with gentle steam and slender appearance even so many years.
