Roof base with half-timber construction


The roof frame and uppermost joist layer form a cohesive structure. With larger cornices, the roof is raised by saddling the rafters over a half-timber construction. As a means of ensuring stability, some of the rafters – usually every third – are fitted with a cross brace.

The cornice shown is constructed of ordinary brickwork. Increased load distribution is achieved by using specially designed stones or corbels, and occasionally iron inserts. For larger load distribution, the wall above the joists is increased in thickness to provide an increased counterweight.
