Lay the joists out in the traditional manner on the supporting masonry at the
specified pitch ensuring that:
 |
there is a minimum bearing length of 90 mm
on the inner leaf of the wall and |
|
the joist stops short of the outer face of
the inner leaf by at least 6 mm (¼”) |
|
if using an I-beam joist, the voids to each
side of the joist web are filled for at least 70 mm with plywood packing
pieces or a proprietary end fitting as supplied by the joist manufacturer. |
Note: the
joist is supported, and remains supported, directly on the masonry.
