Mnogorjadnaja bandaging system at a laying of columns is forbidden, because it does not provide solidity and demanded durability of columns. The single-row system of bandaging, with shift of alternating numbers 1 / 4 a brick, is reached by packing of three-chetvertok that is unprofitable for a laying of columns as at such way it is necessary to apply a considerable quantity trehchetvertok. Therefore columns spread on three-row system of bandaging if bandaging drawing can be admitted on conditions of furnish of a surface of a laying. A laying carry out from the whole brick with addition of halves. At this system of a laying coincidence of external vertical seams in three numbers of a laying on height is supposed. A tychkovyj number stack through three lozhkovyh. For a laying the insignificant quantity of not half-number brick, for example, columns section 2X2 a brick (fig. is required 52, tie up the whole bricks, and in columns section 1 1 / 2 or 2X2 a brick (fig. 52, in each four numbers of a laying stack on two halves.
