Columns & recommendations
Aluminium, cast iron and steel columns
Any failure to follow the assembly instructions and recommendations
could lead to a risk of injury or damage to property.
Column strength calculation
The columns are designed to withstand a given and known load, in
accordance with the stresses encountered in a geographical zone and
location. Any addition of accessories (banner, garlands, planters,
signboards etc.) must absolutely be first verified by our technical support
department.
All the columns are supplied with anchor bolts that are sized for a given
location and load. The project owners are responsible for the dimensions
of the foundation block. The dimensions provided by our technical
support department are stated for guidance only and must be validated
by a specialised civil engineering firm.
Column mounting
With all types of assembly, it is imperative to provide a drain to carry
condensation water from the column out of the concrete. When
aluminium columns are used with steel anchor bolts, anti-torque washers
are provided and must necessarily be put in place. Cover the heads of
bolts and nuts with a protective cap filled with grease in order to keep
them safe from oxidation and allow the annual maintenance of columns
(tightening). The base plate of the column should not be covered. If the
column is installed in the ground, the foot of the column and the base
plate must be protected by means of chemically and electrically
insulating coating, such as of the bituminous type (see “Surface
Treatment”, next page).
> Recommended assembly
Install columns with base plates directly on the foundation (concrete
foundation block), which must be smooth, flat and horizontal (fig. 1
and 2).
> Assembly with semi-rigid system
A semi-rigid device may be used between the base plate and the
concrete foundation block in order to keep the support vertical and
make sure that the base plate is placed correctly (fig. 3).
> Assembly on nuts
Offset assembly on nuts is tolerated on the only condition that the
free space under the base plate is filled with anti-shrinking filling
mortar (fig. 4).
Bitumen protection
Anti-corrosion protection applied at the foot of the column and on the
base plate at a standard height of 300mm, as an option (see “Surface
Treatment”, next page).
Storage of columns
Columns may not be stored directly on the ground or near powdery
material storage areas. Ventilation must be provided for long-term
storage and the metal bands must be removed.
Maintenance of columns
For annual maintenance, the recommendations of the lighting syndicate
will determine the application of the guarantee.
> Check the mounting of brackets, luminaires and accessories.
> Check if all the screws are present and properly tightened.
> Check if the bracket and luminaire are properly fitted.
> Clean the surface of the column with soapy solution if the columns
are made of brushed aluminium or galvanised steel and use a
polishing agent for coated columns.
> Check starting corrosion or cracking in columns in order to take
action as early as possible.
Passive safety (impact resistance class)
Indal columns belong to class 0 (EN 40). The mechanical strength of a
column is compromised when it is involved in an accident. The column
should then be removed and made safe.
