For supporting joists opposite each other on either side of a wall or beam and
where Fire Regulations require the timbers to be separated. Adjoining floors are
kept level.
Noise transmitted between rooms is reduced.
Options
Joist hangers are also available in stainless steel to special order.
Fixing
The back plate of the hanger should lie flat against the supporting masonry,
which should be smooth. The underside of the masonry flanges should bear
directly upon the supporting masonry wall whenever possible. If packing between
the masonry flange and the wall is necessary, the packing must have a
compressive strength at least equal to the supporting masonry and it must extend
over the full bearing area. Joists should be cut to fit tightly to the back face
of the hanger and be fixed securely through the holes provided in the side
flanges.
Supporting masonry and masonry up to 900mm above should be allowed to fully cure
before any load is applied to the hanger.
Technical
Our joist hangers comply with the requirements of B.S. 6178 Part 1, 1990. They
are stitch welded and galvanised to BS EN ISO 1461.
