Detail of Construction at Purlin

In the illustration below is shown a detail of the construction at the purlin. The purlin is made of two 2 in. x 10 in. held apart by blocks, or spacers, at intervals of about 3 ft. The purlin is supported by the purlin post which is cut to receive it, as shown in the illustration.

 

A two member strut connects the purlin and purlin post with the truss principal. One end of a 2 in. x 6 in. diagonal brace is spiked to the purlin, 4 ft. from the bent. The other end is securely spiked to the truss principal. On the other side of the truss another angle brace is spiked in like manner, as shown in the illustration.

Note particularly how the various members are joined and knit together. There can be no sagging roof with this kind of
construction.
