Positioning of the counterplate with chemical bolts:
To ensure the hold of the fixing operate as follows:
a) Check that the inclination of the surface where the counterplate is to be fitted is within the tolerances
shown in fig. 25; otherwise level the surface. Do not insert shims between the floor and
counterplate.
b) Drill the cement surface with a punching machine or core borer using the counterplate as a
template.
c) Accurately clean with sprayed water and a pipe cleaner.
d) Follow the assembly instructions for the bolts used.
e) Once it has been embedded, the work time when the bars need to be positioned and the time in
which it is necessary not to work in order to let it harden completely, are specified on the instruction
booklet present in every package of bolts.
f) After the time required for curing has elapsed, position the counterplate with the hole slits (if
present) facing upwards and fix it following the instructions in the bolt booklet.
The fixing of the column using chemical bolts, needs a scrupulous check of
suitability in relation to the type of support flooring. The suitability checks are the
responsibility of the user and must be carried out by expert, qualified technicians
who will evaluate the feasibility and formally assume the relative responsibilities.
