Materials
The materials
needed to construct a prestressed member are mainly Cable (Strand) and
Anchorage (Anchor). The
cables are manufactured in a variety of standards and grades and in different
diameters. Anchors
may also be single-stranded or multi-strand.
Although
ArmeGroup is not a strand producer, but as a supplier, it has the ability to
supply strand from various sources. ArmeGroup
has various experiences in the field of supplying the most famous strand
manufacturers around the world. In addition, the warehouse of this group always
has a decent amount of strand to meet the needs of respectable customers.
In
the field of Anchorage and its accessories, along with the supply of the most
prestigious international manufacturers, some products of this collection can
also be presented to respected customers.
Equipment
The required
equipment includes hydraulic jack, hydraulic pump, basket machine, dead end jack,
grout injection pump, and more. Jacks
of different capacities or tonnages may be used to carry out tensioning
operations. Typically,
mono strand cables used in slabs are tensioned with single jacks (center hole
ram or twin arms). Multi
strand jacks should be used to carry out tensioning operations in beams,
bridges, tanks, silos, etc. used multi-strand cables. Depending
on the diameter and number of cables, the capacity of the multi-strand jacks is
different. In
bonded systems, grouting is required after tensioning. This operation must be
carried out by a grout injection pump. Similarly,
in unbonded systems, in some cases it is necessary to press the dead end to the
ends of the cables. To
do this, you need a Dead End jack.
