Salient Angles

Several examples of these are shown in Figs. 25 to 39, 71 to 80, and others.

Re-Entering Angles. - Junction Of Two Brick Walls

Figs. 90, 91 are the plans of two courses of the junction between a main wall 2 1/2 bricks thick, and a wall at right angles to it 2 bricks thick, both in English bond.

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.

A course of stretchers may, however, be inserted occasionally to improve the bond between the walls, although it leads to straight joints in the walls themselves.

Hoop-iron bond (see Part II.) may be used with advantage in such positions.

The bond for external or internal re-entering angles is shown in Figs. 25 to 39, and in Figs. 71 to 80.

Junction Of A Brick And Stone Wall At Right Angles

This may be effected in either of two ways: -

1. Stones at short vertical intervals, each equal in height to an exact number of courses of the brickwork, may be allowed to protrude from the stone wall into the brickwork.

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.
