Several examples of these are shown in Figs. 25 to 39, 71 to 80, and others.
Fig. 90. Junction of Brick walls.
Fig. 91. Two alternate Courses.
In every alternate course of the principal wall, exactly opposite the junction, is inserted a row of closers, in length equal to the thickness of the other wall (see Fig. 90).
The intermediate courses are built as usual in both walls, and merely butt against one another, without bond, as in Fig. 91.
The bond for external or internal re-entering angles is shown in Figs. 25 to 39, and in Figs. 71 to 80.
This may be effected in either of two ways: -
2. The brickwork may penetrate the stonework in blocks, each of which consists of about 4 courses in depth, and is separated by about the same depth from the blocks above and below it.
The former plan is the stronger, and has the advantage of clearly showing the bond at any time; but with the former plan the brickwork must be plastered, if the appearance of the stone bonds is objected to.
