It is very often necessary to constructa partition in some story of a building above the first and in such aposition that there can be no support beneath it such as another. =15—. —=— ?^- Fig. 215. One Form of Trussed Partition partition. In this case the partition must be made self-supportingin some way. The usual method is to build what is known as atrussed partition. This consists of a timber truss, light or heavyaccording as the distance to be spanned is small or large, which isbuilt into the partition and covered over with lathing and plaster-ing or with sheathing. Figs. 215 and 216 show two forms of trussed partitions whichare in common use. The one shown in Fig. 215 may be employedfor a solid partition, or a partition with a door opening in the middle,while the one shown in Fig. 216 is applicable where the wall mustbe pierced by door openings in the sides. The truss must be so 162 CARPENTRY 151 designed that it will occupy as little space as possible in a lateraldirection, so that the partition need not be abnormally thick.
