4.3.3 GBA
– CBE: Assembly of the pillar (foundation plate, counterplate, pillar)
•
The column can be anchored to the ground in the following manners:
o
using the foundation frame with stay bolts embedded in a plinth formed in
reinforced concrete.
o
using bolts and expansion bolts or with chemical anchoring.
•
The anchoring of the column using bolt, expansion bolts or with chemical
anchoring, needs a scrupulous check of suitability in relation to the type of
support flooring.
•
The technical data so that the customer can dimension the foundation plinth, are
indicated in the table shown in paragraph 2.2.9
”. The plinth must be dimensioned in relation to the real
consistency of the ground and the specific maximum pressure that it can allow.
•
The suitability checks of the foundation are the responsibility of the user and must
be carried out by expert, qualified technicians who will evaluate the feasibility and
assume the relative responsibilities.
Positioning of the foundation frame in the plinth:
1) Screw the lower nuts

on the stay bolts

letting the threaded portion protrude until obtaining the
corresponding protrusion
ST
(see paragraph 2.2.9) (fig. 22). Carry out this operation on all 8 (eight)
stay bolts.
2) Insert all of the bolts

in the holes of the foundation frame

so that the plate of the frame sits on the
nuts and tighten with the high nuts

inserting the washers

.
3) Embed the frame prepared this way in the plinth casting making sure that the upper plate remains flush
with the floor (fig. 23). Protect the threading of the bolts to prevent damage.
4) If required, prepare insertion of a pipe in the plinth adequate for passage of the electrical cable to supply
the jib crane (fig. 24)
5) Level the foundation frame, possibly using a level and fill and scrape the plinth (fig. 25)
6) Wait for the time necessary for the plinth to solidify before mounting the column.
