Manufacture of oven works (a part 2)

the Splitting and teska a brick. In the course of a laying a brick it is necessary to split, give it klinovidnuju the form. For an arch laying, otesyvat one party for the device of heels or to round off, for example, for its application in channels that provides the best movement of gases on them (fig. 159).

the Splitting and teska a brick: and - a splitting across (it is correct and wrong), - a splitting lengthways, in, g - working position of the stove-maker accordingly at a splitting and teske a brick prick normally burnt brick without a notch, on the planned line: on poorly burnt brick at first do a notch on which then carry out a splitting. A notch put on all perimetre of a split part depth to 5 mm. Split a brick so. The left hand hold a brick, right a hammer or kirochku with which strike in a proper place strong blow. Thus the edge of a hammer or kirochki should be directed at right angle in relation to a brick or a splitting line. Slanting blow often leads to any splitting. It is possible to put some blows, gradually increasing their force while the brick will not break up. During splitting lengthways a brick hold or in the middle or for its big part (fig. 159,).

At teske a brick take the left hand and put it on a knee (fig. 159. The end kirochki strike to a brick easy blows with a direction downwards on itself. At first carry out rough otesku a brick, a blunt end kirochki putting stronger blows, and then the sharp end strike frequent not strong blows.

laying Receptions. For reception of a beautiful laying and acceleration of performance of works a brick preliminary display into place where it should be in the furnace so that the seam between bricks was 3-5 mm. In the course of a laying bricks serially or all remove at once, stack near to a workplace, and then put on a clay solution, spreading the furnace.

The Solution in the course of a laying put on a brick and spread hands or kelmoj. At rasstilanii a hand the solution in addition mixes up, from it stones, clay clots leave. However hand wounds by sharp grains of sand are thus possible also. Kelma protects hands from wound, to work as it more proizvoditelno as it is possible to cover with a solution at once some bricks. At the same time kelma does not give possibility to feel stones and grains of sand that leads to decrease in quality of a laying (fig. 160, 161).

160. Drawing of a solution by a hand: and - imposing and levelling by a hand glimnjannogo a solution. - hand position at brick packing on a solution, in - podgrebanie a solution a brick edge, g - brick pressing into place with solution expression; 161. Solution drawing kelmoj: and - imposing of a solution with preliminary rasstilaniem (levelling), - alignment of a solution along the edges of a laying. In - levelling; 162. Versions of seams: and - vpustoshovku, - vpodrezku, in - embroidered convex. g - embroidered bent Drawing and rasstilanie a solution make so. The left hand remove brick earlier laid dry, right take away a solution from a box and transfer it to the place of packing. Moving a hand on bed nizheulozhennogo a brick, fingers level and smear a solution a uniform layer of the necessary thickness (fig. 160). A brick being in the left hand immerse for some seconds in a bucket with water, then on tychkovuju a side impose a few solution to form a vertical seam. After that a brick stack on a place, pressing its one or two hands and moving back and forth for reception of a thin seam.

The Laying can be conducted, without imposing a solution on tychkovuju a side. Do it so. The brick taken out from water put on a solution not horizontally, and a few having raised the back party and having lowered a lobby on a solution that at advance tychkovaja the side has typed on itself a solution and has moved it to earlier laid brick. A brick densely press, moving up forward and squeezing out thus surpluses of a solution. The solution squeezed out of seams there and then clean, removing it at once two hands.

It is possible to put a solution directly on the stacked brick moistened with water, instead of on an underlaying number of a laying. In this case a solution preliminary stack a hill in a proper place, then on a face side of the brick taken out from water put a solution and stack it the same as it has been described above.

The brick Laying should be carried out very quickly as the solution dehydrated by a brick, gets denser also it it is impossible to lay and level a thin layer. Durability of a laying in many respects depends on correctness of preparation of a brick. The scarlet brick from water is scattered, therefore it in the course of a laying quickly dip into water, there and then take out from it and put on a solution. Such brick quickly soaks up water from a solution therefore last gets denser. Thus seams turn out thick, and coupling of a brick with a solution weak. A fire-resistant brick also only rinse with water.

The Good brick moisten in water 3-5 with. Such brick absorbs water from a solution less, the seam turns out thin, and a laying strong. For reception of a strong laying with thin seams (3-4 mm) a brick hold in water until from it air vials will not cease to be allocated.

To an oven laying apply various seams (fig. 162). At oshtukaturivanii for the best deduction of plaster on a surface of the furnace seams leave furnaces not filled on 5-10 mm. Such laying is called as a laying vpustoshovku. if will not bake to be plastered, seams fill completely. In this case a laying name a laying vpodrezku.

Facing by a fire-resistant brick make so that it did not tie with a red brick. Because of various temperature expansion of these kinds of a brick the laying can collapse.

At a laying of pipes on limy, difficult and cement mortals seams can be embroidered, giving them the convex or concave form. To this purpose apply the special tool - rasshivku.
