The base of the furnace must satisfy safety requirements. If there is no cellar under the structure, then on the ground floor for the furnaces, separate, not related to the foundation of the house, bases in a depth of 0.5 to 0.9 m (depending on the density of the soil) — stone or brick; bases are usually placed on a lime solution. Medistant stoves, t. e. stoves leaned by one side against the stone wall, or corner furnaces placed next to the thin inner wall, are based on the remaining floors of stone buildings on 2 or 3-rolled or taurus iron Ts 16 under the underpers of the transverse beams. One end of these subpoons is fried on a solution of Portland cement into the wall to a depth of at least 35 cm, and the other end is left freely by weight.
The industrial gates are automatically used at such facilities where you constantly have to open t. e with a high degree of saturation. A great example for using automatic gates is car wash, warehouses, and other production facilities.
This type requires calculating stability verification, t. To. Thin, lungs 38-centimeter walls do not hold heavy (1600-1800 kg/m8) furnaces. Under the backs on the outer edge of the wall and above the ends, the back of the wall is placed either iron or stone (from solid stone) ascent for distribution of pressure to a large area.
In the base of the corner furnace, the iron transverse Taurus 7 beam ms is naughty into the walls> 12, or directly from the wall to the wall or bending the ends towards the inner wall.
In the iron structure of the base of the furnace, a redness of brick or concrete with a thickness of one brick is placed, aligning horizontally the surface of the arch (if necessary) with tiles. Iron beams over which the arch is laid are fastened with each other by either iron crutches or twisted wire to avoid the expansion of the beams of the furnace with the weight of the furnace.
It is recommended to place a concrete plate between an iron beam and a wall. Iron beams can also be covered 6 to 7.5 centimeter boards, over which, in this case; Bricks are placed as an insulator — two rows are flat, but this undesirable increases the height of the base of the furnace. It is better to cover the boards with iron tin thick, at least 1 mm, covering the last 15 mm chamotte slabs.
It is also good to cover between the ceiling space under the stove with a crowd or felt, soaked in clay, or a layer of clay with a thickness of 5 cm; When the clay dries, the cracks are poured with a solution and then a layer of sand or slag is poured, about 7 cm.
In wooden buildings of the furnace, if they are not heavier than 750 kg t. e. volume no more than 0.5 m; placed directly on the transverse beams, which should be 2 cm thicker than the rest of the beams of the same room. The beams are overlapped with boards with a thickness of 6 to 7.5 cm, over which they put a brick in two rows flat or a 5-mm alphabet strip, putting forward the last 50 cm in front of the furnace doors. Above the alphabet is nailed iron tin.
