Bond Odd Course
In the Figure A above layout
of odd course in a English bond brick L-
joint. The odd course has the facing, consisting of stretcher course as shown in the Figure A above. Further if we focus
on L-joint stretcher in corner has a
queen closure placed parallel to it, as shown in Figure C.

Behind the queen closure, bricks are placed
parallel to it such that the outer facing has a course of headers as in Figure D. Each stretcher in
the facing has backing of a stretcher in odd course. Hence odd course appears
similar to facing side as in Figure E.

If we zoom into L-joint, Header in the corner has bricks placed so that the other side has a course of stretchers Figure G in the side.Parallel to queen closure bricks are placed such that we have course of headers here Figure H.

bond Bond Odd -Even Courses comparison
Figure I : Comparison of even - odd course |
Queen closure placed in the even course beside
the quoin header helps to bring about necessary course lap. Every header comes
exactly in the centre of stretcher below
it. Joints in stretcher course come in centre of headers of the courses above
and below such that sufficient course lap is got here. This is the reason this
bond is considered strongest as compared to other bonds.
