- The finished bearing units are
identified by type, size or other markings specified by the engineers.
- Rubber bearings are robust and
not easily damaged but it is prudent to treat them with a certain
amount of care to avoid the possibility of accidental damage.
Before installation
- Handle carefully. Use a crane
if necessary.
- Store under cover in clean conditions
and out of direct sunlight.
- Do not remove transit clamps
when fitted.
During installation
- Handle carefully. Use a crane
if necessary.
- Ensure correct location and
orientation.
- Bearings must be fully supported
over the entire area.
- Bearings must not be subjected
to excessive loads - even for short periods.
- When setting levels, do not
apply uneven loads or hammer blows to bearings.
After installation
- Remove any temporary restraints
and check that the bearings' upper faces are in contact with
the supported structure.
- Remove bedding mortar from the
side faces of elastomeric bearings.
Most important
- NEVER install a damaged bearing.
- NEVER apply uneven loads or
hammer blows to elastomeric bearings.
- Should a bearing be damaged
the resident engineer must be informed and a replacement ordered.
The installation positions are generally detailed on the engineer's
drawings.
- The surface onto which bearings
are installed should be flat and level with no projections or
air holes.
- Preferably a self-levelling
epoxy grout should be used to create a smooth surface.
- The bearings are designed to
be installed without adhesive, however if it is deemed necessary
to locate the bearings, then a suitable epoxy adhesive should
be used.
