STEEL CONSTRUCTION
MASONRY BLOCK
CONSTRUCTION
Fig: 2.1.1
WARNING! Masonry blockwork should be properly filled and
reinforced if brackets are to be mounted directly to blockwork
with masonry anchors. Where the blockwork is not solidly filled
but structurally sound, long bolts should be passed through the
blockwork using suitable steel plates under bolt heads.
Special consideration should be given to brick type and
construction of wall, to ensure satisfactory fixing e.g. welding
detail if fixed to steel.
WARNING! The installer
must select and use
fasteners appropriate to
the material into which
they are being fixed.
important notes
a) For installation to materials
not covered in the chart,
the installer should seek
expert advice from a
qualified builder.
b) Minimum length of fastener
does not exclude use of
longer lengths. Decision
must be made by fitter to
ensure adequate strength.
c) Recommendations for old
materials or materials not
in good condition are not
included. If in doubt about
the strength of the material
seek specialist advice.
d) Fasteners for brackets in
masonry should be at least
5/16” x 2.5” long or metric
equivalent.
