Ways of a laying . Labour productivity of the mason depends on ways of a laying of a brick and ability to apply them at work on various solutions. Versts spread in three ways: vprizhim, vprisyk and vprisyk with podrezkoj a solution, zabutki - vpoluprisyk. The choice of a way of a laying depends on plasticity of a solution, humidity of a brick, a season and requirements to cleanliness of a face sheet of a laying.

In the Way vprizhim, stack a brick in lozhkovye (fig. 34) and tychkovye (fig. 35) versts on a rigid solution (a deposit of a cone 7... 9см) with full filling and with rasshivkoj seams on an obverse surface of a laying.

Thus a solution spread with a space from a wall face sheet on 10. 12мм. The mason levels a solution, the back party kelmy, moving it, from the laid brick and arranging rastvornuju bed simultaneously for three lozhkovyh or five tychkovyh bricks.

The Mason carries out operations in such sequence (fig. 34 and 35 see): holding in the right hand kelmu, levels it rastvornuju bed, then an edge kelmy the part of a solution rows up and presses it to a vertical side before the laid brick, and the left hand brings a new brick to a packing place (poses. 1); after that lowers a brick on the prepared bed and, moving its left hand to earlier laid brick, presses to a cloth kelmy (poses. 2). Movement of the right hand upwards, takes out kelmu, and a brick which is moved up by the left hand, clamps a solution between vertical sides stacked and before the laid brick (poses. 3 ). Hand pressing rebuffs the laid brick on rastvornoj beds. The surplus of the solution which has been squeezed out of a seam on the person of a laying, cuts kelmoj at one time (poses. 4 ) after packing tychkovymi bricks of each four-five bricks or after packing by spoons of two bricks; The cut solution the mason throws on rastvornuju bed. The laying turns out strong, with continuous filling of seams with a solution, dense and pure. A lack of this way that it more labour-consuming, than others as the mason should do many movements.

In the Way vprisyk , a brick stack on plastic solutions (a deposit of a cone 12... 13см) vpustoshovku, i.e. With incomplete filling (on 1... 1,5см) seams on an obverse surface of a laying. For this way the plastic solution is required.

The Solution spread a bed with a space from an external vertical surface of a wall on 20... 30мм that at a laying the solution was not squeezed out on an obverse surface of a laying.

the Laying in the way vprisyk (in figures the sequence of operations is shown): and - lozhkovogo a number, - tychkovogo of some

a Fig. 36. A laying in the way vprisyk (figures - sequence of operations) :
And - lozhkovogo a number, - tychkovogo a number

Lozhkovyj a number (fig. 36, spread in such sequence. Taking a brick and holding it naklonno, the mason gets tychkovoj a side of a brick a solution part (поз.1) outspread on bed, beginning approximately on distance 6... 10см from earlier laid brick. Moving up a brick, to earlier laid brick, the mason gradually amends its situation and presses to bed (poses. 2). Thus the part of the solution which has been removed from bed, fills a vertical cross-section seam. Having laid a brick, the mason rebuffs his hand on rastvornoj beds (poses. 3 ). At a laying tychkovogo a number (fig. 36,) process carry out in the same sequence, only a solution for formation of a vertical cross-section seam row up not tychkovoj, and lozhkovoj a side (poses./). This way the mason can stack a brick both left, and the right hand. At laying erection in seismic countries it is not supposed to stack this way bricks in verstovyh numbers.

the Laying with podrezkoj a solution tychkovogo a number in the way vprisyk (in figures the sequence of operations is shown)

a Fig. 37. A laying with podrezkoj a solution tychkovogo a number in the way vprisyk (in figures the sequence of operations is shown)

The Way vprisyk with podrezkoj a solution (fig. 37) apply at erection of walls with full filling of horizontal and vertical seams and with rasshivkoj seams. Thus a solution spread the same as and at a laying vprizhim, i.e. With a space from a wall face sheet on 10... 15мм, and a brick stack on bed the same as at a laying vprisyk. The surplus of the solution which has been squeezed out of a seam on a face sheet of a wall, cut kelmoj, as at a laying vprizhim. A solution for a laying apply more rigid, than to a laying without podrezki (mobility 10... 12см): at excessive plasticity of a solution the mason will not have time to cut off it at expression from laying seams. On laying performance vprisyk with podrezkoj a solution it is spent more time and work, than for a laying vprisyk, but it is less, than on a laying vprizhim.

the Laying zabutki in the way vpoluprisyk (in figures the sequence of operations is shown): and - tychkami, - spoons

(By figures the sequence of operations)
is shown:
And - tychkami, - spoons

In the Way vpoluprisyk carry out a laying zabutki (fig. 38, and,). For this purpose, at first between internal and external versts spread a solution, then level it then the mason stacks a brick in zabutku. Thus it works usually as two hands, grasping simultaneously on 2 bricks. A brick at packing hold almost flatwise, on distance 5... 8см, from earlier laid brick. Gradually lowering a brick on rastvornuju bed, get an edge insignificant quantity of a solution (poses. 1 ), move up a brick closely, to earlier laid brick, and pressing of hands (poses. 2 ) rebuff it into place. Vertical seams remain thus partially not filled. Them fill at rasstilanii a solution for a following laying on number height, and the mason watches that cross-section seams between bricks were filled completely. Bad filling of vertical cross-section seams with a solution not only reduces durability of a laying, but also increases produvaemost walls that reduces their heat-shielding properties. A brick zabutki densely press to bed to level laid verstovyh numbers. Laying process zabutki is simple, it is carried out also by masons of 2nd category.
