PASCHAL's TTK circular
trapezoidal girder formwork with clamp connections is a reliable and flexible
formwork system enabling perfect curves and dimensional accuracy – a top-rate
product for circular formwork.
Constructing round concrete
structures is a task not frequently undertaken, especially for smaller
construction companies, and can therefore be challenging.
Since the launch of the
circular trapezoidal girder formwork in 1975, PASCHAL has continuously worked
together with construction site professionals to make PASCHAL circular formwork
both simpler and more versatile to use. The last major development was the
introduction of the TTK circular trapezoidal girder formwork.
For construction companies
looking for an all-round reliable formwork solution, it is an excellent choice
with its fully variable adjustment range and fast segment connection as well as
perfect roundness and dimensional precision.
Even less experienced
construction teams can deliver top quality, especially in projects such as
sewage treatment plants, water parks, towers, staircases, garage entrances or
in landscaping and container construction.
As an extra help for such
customers with challenging circular formwork tasks, PASCHAL also supplies
construction sites with formwork has already been rounded upon request.
TKK
circular trapezoidal girder formwork: The perfect choice also
for large construction companies
The product's features
speak for themselves and have already impressed many clients around the world.
After the reinforced
concrete base structures had been completed, Detlef Lenschow, site manager of
OBG Tiefbau GmbH & Co. KG was very satisfied with installation times and
quality of work and emphasised that TTK's dimensional accuracy, robustness and
ease of handling was key to this success.
There has also been plenty
of international praise. Hiroki MAENO,
GIFU INDUSTRY CO., LTD. travelled all the way from Japan to bauma 2022 to get a
first-hand look at the circular trapezoidal girder formwork and was impressed:
"Quality, functionality and other benefits of using the system were
instantly apparent to me. I'm looking forward to importing one of the systems
and being the first to use the PASCHAL circular trapezoidal girder formwork in
Japan."
Overview
of benefits:
Absolutely circular and
dimensionally accurate PASCHAL's circular trapezoidal girder formwork is
designed for perfect and reliable roundness and dimensional accuracy. The ideal
trapezoidal girder geometry provides superior support for formwork plywood,
thereby achieving uniform roundness.
System
enables any curved shape to be formed
Any curved shape, including
non-circular curves such as ellipses or spirals, can be formed in the system to
centimetre accuracy thanks to the fully variable adjustment range from 5 m
diameter to straight, an optimum range of segment heights and widths, and the
required plastic fillers – with no time-consuming, on-site length adjustments
required.
Fast forming times achieve
goals easier and quicker Even new construction teams can achieve better forming
times using the circular trapezoidal girder formwork instead of the large-area
formwork for straight walls.
TTK is ready for immediate
use, because the formwork can be supplied already rounded and stacked whenever
required. PASCHAL also supplies construction sites with the fillers required
for radius-adjustable circular formwork, together with the large formwork
segments. No expensive, on-site solutions are therefore required.
The very low number of
clamping points also enormously reduces installation times and the subsequent
closing of the points. Fresh concrete pressure absorption of 60 kN/m² for all
segments and all formwork heights are fully maintained and comply with flatness
tolerances specified in DIN 18202, Table 3, Line 7.
Innovative
clamp connection technology
The use of clamp connection
technology and the reduced numbers of connecting pieces enables very good
forming times to be achieved. To ensure that the clamps are instantly available
at the right place when re-assembling the formwork, they can be hooked into
keyholes in the steel trapezoidal girders, ready for use. This further minimises
the forming times.
Continuous height
offsetting between the individual segments is also possible, allowing the
formwork to be perfectly adapted to sloping ground.
Overcoming
any challenge
Formwork for haunches or inclines is also easy to implement using the circular trapezoidal girder formwork. Technically advanced system solutions have been designed for this: adjustable haunch beams for direct forming of haunches and fully extendible telescopic insertion beams for adjusting to inclines.
