Recommendation points



The Russian stove (oven) is a unique construction of our ancestors, which not only warms, but also feeds, heals, and also ventilates the room. With the multivariance in the details of the form, its main components remain unchanged. In the article we will consider the design of the Russian stove and its ordinal laying..

Even before the introduction of the modern measurement system, the traditional dimensions of the Russian stove were calculated in arshins. 1 arshin is approximately equal to 71 cm.The oven had 2 arshins in width, 3 arshins in length, and the height of the main body of the oven from the base of the guardhouse to the bed was 2.5 arshins.

The design of the Russian (oven) oven

There are three main components in the oven:

  1. Foundation.
  2. Housing.
  3. Chimney.

Foundation

Our ancestors used rubble stone or overheated brick for the foundation. Without departing far from the traditions of the past, we will consider the option of a concrete foundation for the furnace body.

The depth of the foundation for the furnace depends on the properties of the soil, whether the building is heated during a cold period of time, what is the level of groundwater. In the case of non-constant heating of the building, the depth of the base of the foundation is provided below the depth of soil freezing in the coldest time.

Rubble concrete consists of concrete mix and rubble stone. For the foundation, it is enough to use concrete mix M200. Concrete mix M200 is obtained with the following composition:

  • cement M400 – 1 part;
  • sand – 2 parts;
  • gravel or crushed stone of fraction less than 3 cm – 4 parts.

For the manufacture of concrete, sand is taken with a minimum amount of organic, clayey, dusty, mica impurities, which significantly reduce the strength and frost-resistant properties of concrete.

Water is poured into the dry mixture of cement, sand and gravel gradually, with constant stirring of the ingredients until the required fluidity of the mixture is achieved. In this case, the volume of water is approximately equal to the volume of cement taken.

The foundation for the furnace can be constructed both with the help of formwork and without formwork, with dense non-crumbling soils and the depth of the base of the foundation less than 1.25 m. In the case of a non-formwork device, the size of the pit must correspond to the size of the foundation. It is necessary to lay a layer of compacted crushed stone with a thickness of at least 10 cm under the base of the foundation.

Rubble concrete masonry is the process of embedding rubble stone into a layer of a laid concrete layer 20 cm high. The rubble stone should be less than 30 cm, it is immersed in a concrete layer to a depth of more than 1/2 of its height. The gap between the stones being laid, as well as between the stone and the formwork is 4–6 cm. When the rubble layer is completely laid, the next layer of concrete is laid and the process of embedding the stone is repeated.

To achieve the full quality of concrete work, breaks in the process of laying the foundation are allowed only when the gaps between the stones are filled with concrete of the last layer. In dry, windy or hot weather, with interruptions in work for more than a day, to prevent rapid drying, the concrete surface is covered with some kind of material (you can tarnish) and moistened with water 3-4 times a day. Before resuming work, the surface of the last layer is cleaned of dirt and moistened with water.

Rubble stone can be replaced with fragments of red brick or pieces of concrete, while the aggregate of the concrete mix can be brick rubble. Stones, fragments of bricks must be thoroughly cleaned of dirt before being immersed in the concrete mixture. In dry and hot weather, in the case of using broken bricks, the fragments are soaked in water before laying.

The timing of concrete gaining strength depends on its temperature. At a temperature of 10 ° C, in the first day, it will gain about 10% of its full strength, in 7 days about 60%, and in 28 days – 85%. With an increase in the temperature of concrete, the terms of its full strength gain are reduced. It is necessary to start masonry on the surface of the foundation no earlier than after 14-28 days.

Furnace body

In a Russian hut, a stove was installed in a corner not far from the door. About 20 cm receded from one wall, and about 1 meter from the other, where the entrance door was. In this place, a closet was often equipped, where food and kitchen utensils were stored..

On the surface of the foundation, which has gained strength, 2 layers of waterproofing material (roofing felt, roofing felt, etc.) are laid. Next, the base of the furnace (guardianship) is laid out. In the classic Russian stove of the past, a wooden bar or log was used for this..

The base served for storing kitchen utensils, and stove implements (grabs, pokers, frying pans) were placed in the oven. Now this part of the furnace is laid out mainly of brick (ordinary clay). And you need to use full-bodied. The brick is front and ordinary. The front one is used for cladding, the ordinary one is used for the internal masonry of the furnace. For surfaces in contact with open fire, it is necessary to use refractory bricks (chamotte), which can withstand temperatures of more than 1300 ° C.

Clay-sand mortar

The amount of sand in the clay-sand mortar is determined depending on the fat content of the clay (oily – 2–4% sand, medium – 15% sand, lean – 30% sand). To achieve the highest quality masonry, sand must be taken sifted through a sieve with 3×3 mm cells.

The proportions of clay-sand mortar:

  1. Oily clay: 1 bucket of clay, 2.5 buckets of sand.
  2. Medium clay: 1 bucket of clay, 1.5 buckets of sand.
  3. Skinny clay: 1 bucket of clay, 1 bucket of sand.

To prepare the solution, several buckets of crushed clay are placed in a container and filled with water for 24 hours. Then add the required amount of sand in portions to the soaked clay, constantly stirring until a homogeneous consistency.

Materials

The construction of the guardhouse itself is made of ordinary clay bricks on a cement-sand mortar based on M400 cement, in a proportion: 1 part of cement and 3 parts of sand. The necessary mobility of the mortar can be checked by placing part of it on the bayonet of the shovel at an angle of 45 °. In this position, the finished solution should not drain. Before starting laying, the bricks are soaked for better adhesion to the mortar.

For the entire structure of the furnace, approximately 1,500 to 2,500 pieces of bricks, including refractory bricks, will be required, depending on the height of the room and the roof structure. The consumption of clay and sand in the mortar is about 80 buckets. Furnace accessories will require: views, latches and half doors.

The seventh row involves laying the arch and the next row. The arch begins to lay out on both sides, gradually moving towards the middle. The last brick is called a castle brick, its role is to create compressive stress at the base of the arch, which will ensure the strength of such a structure. In this regard, the last brick is inserted into the gap less than 1/4 of the brick using a mallet. The bricks in the vault are stacked as tightly as possible to each other, so the seams at the bottom are made as small as possible, and the upper gaps are made of the same size, into which, if possible, fragments of brick can be embedded.

The twelfth row begins the device of the hot part of the furnace (under, six). Therefore, all surfaces in contact with fire must be made of fire-resistant bricks, the dimensions of which coincide with the dimensions of an ordinary one. The surface of the hearth must be level. To do this, it is sanded with fine sand and bricks, removing all the unevenness of the masonry. In addition, for the convenience of removing coal from the hearth, its surface is made with a slope towards the mouth.

Not reaching three rows to the ceiling, cutting is done to increase the thickness of the brickwork. This increases the fire safety of timber floor and roof structures. Next, the pipe riser is laid out the same dimensions as before cutting. To avoid the accumulation of condensate on the pipe walls, the pipe stand is plastered over a metal mesh. As the pipe passes through the timber roof structures, the wall thickness of the channel also increases. The upper part of the pipe must be protected from precipitation by a metal cap. The outside of the pipe is laid on a cement-sand mortar. For durability, it can be plastered.

Furnace-drying oven

Before full operation of the oven, it must be dried. The first combustion is carried out within 2 hours with a small amount of fuel. If the stove gives a lot of smoke, then a small fire is also lit on the view, when it goes out, the view is opened completely. After that, the stove is ignited again without closing the chimney overnight. The furnace-drying process takes about a week..
