Profile of Our Company
With the purpose of investigation, planning, design, instruction, construction and maintenance of prestressed concrete
structures, Anderson Technology Corporation (ATC) was established in 1979 as a Japanese-American joint enterprise with the
right to implement multi-strands post-tensioning system that was developed by Dr. Arthur R. Anderson (1910-1995), one of the
worldwide authorities on the prestressed concrete. We are intimating with many overseas enterprises and organizations, such
as member companies of Concrete Technology Associates that is led by Concrete Technology Corporation and affiliated with
ABAM Engineers Incorporated in the US. These relationships make us possible to introduce plentiful information and valuable
prestressed concrete technology into Japan.
We have refined on Anderson post-tensioning system to be fit for construction in Japan with various improvements and
provide various materials and technical services in detail. We also developed our own anchorage and coupler, pre-grouted
internal and external tendon systems with transparent sheathing that is called JSAS system.
Also, we are an importing firm of high quality silica fume for producing high-strength / high performance cement and
concrete from North Europe and the US.
We are intending untiringly to proceed with technical development and to persevere in our efforts to meet users' request in
the future.

The anchorage for multi-strand tendon which is fundamental
for the Anderson prestressing system is consisted of compact female cone made of steel and male cone named plug made of
aluminum alloy.
The wedge function of both cones make it possible to anchor
wide-ranging choice of strand from 6 to 12 at the same time.
Because the materials of both cone are rather soft compare
to the prestressing steel, there are no injury coming from the teethmarks of the wedge when anchorage is finished.
For this characteristics, temporal anchorage or de-tensioning
or re-tensioning can be easily done in the stable condition.
Factory fabricated spiral rebar made of high tensile prestressing deformed steel bars are used for the reinforcement of the concrete around the anchorage.

Coupler
Combining the anchorage and coupler, anchoring and coupling work of the tendon can be done by this one unit.
Grouting also can be done separately first stage and second one successively. Structurally, because the
wedge for the primary tendon is apt to tighten when the secondary tendon is tensioned, and there are merits of
that secondary tendon can be tensioned in the stable condition.

OVM 13-12 system (for the tendon of 12S12.4, 12S12.7)
Anchorage
The anchorage, Anderson prestressing system ( wedge system ) , has a small pull-in value and its tensioning
apparatus, jack, has rather light weight of 164 kg and small size.
Grouting can certainly be done at either stage of before and after the filling concrete of recess at the
anchorage as the same way as in AS225M anchorage.
Sectional successive execution in the bridge construction using coupler is also available.

OVM 15-12 system (for the tendon of 12S15.2)
Anchorage
The anchorage, Anderson prestressing system (wedge system), has a characteristic of small pull-in
value(5mm) and its jack weighs rather light,280kg.
Grouting operation can be done either before or after of filling concrete at the recess for the anchorage, as
the same way as the method for AS225M.

JSAS Pre-grouted cable (1S21.8) system
Anchorage
The live anchorage for the Pre-grouted cable which is not necessary to inject cement grout is consisted of
socket (female cone) and wedges. Those parts and the sleeve for the coupler are made of forged iron.
Coupling procedure has been gained high reliability, because the wedges are pushed into the socket by
pushing tool beforehand and those two sockets which have reverse screw each other are connected by the sleeve
putting pressure ring between them, and by turning the sleeve, this pressure ring pushes the wedges firmly.

In this AJ200 series, there are three kinds, i.e. short stroke one (AJ200S), standard stroke one (AJ200),
and long stroke one (AJ200L).
According to the working circumstances of prestressing, most suitable one can be selected. And, double
actioned jack which makes the necessity of re-tension works less can also provided.
