Doka will once again be setting the formwork-technology agenda for years ahead, presenting answers today to the challenges of tomorrow. Even lighter and stronger system components, a revolutionary new load-bearing tower and pathbreaking innovations for forming walls and floor-slabs will be in the spotlight here. With these innovations, Doka is squeezing labour and equipment costs down even further, and laying down a wholly new standard for ergonomic design and safety on the site.

For shoring-tasks in the building construction field, it is common to use load-bearing towers based on single legs. Serious delays and safety risks are encountered when this type of shoring tower is erected and dismantled, however. Doka has analysed these shortcomings and devised a revolutionary framework scaffolding for use in building construction – so revolutionary, in fact, that it redefines the norm for ergonomic design and speed of work. The unique H-shaped frame geometry makes it possible, for the first time, to have barrier-free workplace access routes and work-deck levels extending across several scaffold units at once. This makes working beneath the towerframe superstructure much easier, quicker and safer. What is more, the work-deck levels can be extended beyond the scaffold itself, so as to extend beneath cantilevering superstructures. Safe working is ensured here by easy-to-attach brackets.
The Doka development engineers have also been successful in greatly reducing the dead weight of the Staxo 40 frames while retaining their high stability and load-bearing capacity. To adapt to different heights, Staxo 40 gets by with just three different sizes of frame. Extra, last-millimetre adjustability is provided by screw-jack heads and feet with a total extension length of 140 cm. Their novel thread geometry and three-wing spindle nut permit effortless adjustment, even under full load. The wide inter-frame spaces of up to 3.00 m, using various lengths of diagonal crossbrace, make for maximum flexibility in the horizontal. For optimum adaptability to all layouts, it is also possible to combine single legs with the frame.

Super-short forming-times, yet superlative concrete finishes – a contradiction? Not necessarily. With site-ready, pre-assembled elements that remain dimensionally stable despite having far fewer form-ties and no limits on the pouring rate, Doka manages to achieve both at once. Consisting of ready-to-use standard elements, the heavy-duty Wall formwork FF100 tec has been developed to meet the most exacting requirements regarding the concrete finish. Its high-load-capacity components save 1/3 of the form-ties, with equipment and labour-cost savings to match. Walls up to 3.60 m high can be filled in a single pour, with no need to worry about the pouring rate. Even when sustaining very high fresh-concrete pressures, the system ensures absolutely plane and dimensionally accurate concrete faces. Indeed, the concrete finishes achieved by Wall formwork FF100 tec will gladden the heart of any architect. With its symmetrical form-tie pattern located well inside the element, and its form-facing screwed on from the rear, FF100 tec produces aesthetically appealing and top-quality fair-faced concrete surfaces. The 25 cm element size-grid also has a very positive impact here, as it means that so few closures are needed. With Doka, safety always comes first. This is why there are also ready-to-use platform systems with integrable ladderways available for use with Wall formwork FF100 tec.

Already a world leader when it comes to fast, safe working with tableforms, Doka has now set new benchmarks with two more innovations. These have pulled off a trick that even experts had reckoned was just about impossible: speeding up the repositioning of tableforms even further, with even greater safety, and completely independently of the site crane.
For repositioning tableforms on the same level, Doka now offers its new DoKart. With this innovative new product, Doka has re-invented the shifting trolley, giving it just what it takes to cope with the rough-and-tumble of work on the site. 1-man operation had always been the norm at Doka, of course, and the DoKart is no exception. Compared to the sweaty hard work of pushing and lifting the tables by hand, this gives labour cost-savings of 70%! The great thing about this new compact unit is its extreme manoeuvrability. It can move 90° sideways and turn on its centreline, all of which makes repositioning the tables a lot easier. Even during its on-site test phase, this tremendous user-friendliness got a wildly enthusiastic response from the site crew. The DoKart is robustly built for long life and high reliability, with large wheels that give it generous ground clearance and allow it to move around typical building-site floors safely and unhindered. Its high lifting speed is equally revolutionary. A quick push of the button, and the tableform is adjusted back up to the right height for forming, in just a couple of seconds.
For transporting floor-slab formwork up to the next storey, Doka offers the Table Lifting System TLS. This innovative lifting platform whisks a tableform up to the next floor in only 20 seconds. Once all the tableforms have been moved up from one floor to the next, the TLS itself also needs to be repositioned. Until recently, this was always done using the crane. Now a new, self-climbing version of the TLS makes it possible to form floor-slabs 100 % cranelessly, at the same time as enhancing safety during the lifting operation. This makes the self-climbing TLS particularly suitable for use on tall buildings. As the self-climbing Table Lifting System is structure-guided at all times, it can be safely raised even in poor weather conditions. Particularly when used in conjunction with the Protection screen Xclimb60, this new solution is simply ideal, as both the protection screen and the TLS are “climbed” up to the next casting section using the same technical system. Alternatively, where sufficient craneage is available, the TLS can also be raised by crane, guided on the structure in this case as well. Professional Doka site foremen are available to assist with advice and practical help when it comes to erecting the TLS on-site and training the site crew.

Doka customers constantly benefit from the high utility and cost-efficiency of the latest formwork technology. The advantages of the Xlife sheet, such as better nailability and quicker and easier cleaning, are now also available in the lightweight framed formwork Frami Xlife. This upgrade to the timber-plastic composite Xlife sheet, which also has special tie-hole protectors, hugely extends the service intervals between changing sheets. What is more, the special surface structure ensures the very best concrete results even after many, many repeat uses. On rented formwork, Xlife cuts the close-out costs for reconditioning damaged form-facing, and reduces the amount of finishing-work needed on the concrete.
Also, Frami Xlife can easily be combined with the Framax stripping corner I with the aid of a profile adapter – for fast, accurate forming of shafts.
The fastest way to form rectangular and quadratic columns is with the Column formwork KS Xlife. With its ingenious folding mechanism, this system is simply unbeatable. To make sure that Doka customers also profit from maximum cost-efficiency and long service life when using Column formwork KS, the Xlife sheet is now used as the standard form-facing here as well.

The more unusual the architect’s wishes, the more complex the requirements that are then made of the formwork – such as special shapes involving small numbers of form-tie points and high hydrostatic pressures. Despite this, these are the very projects that always require absolute dimensional stability of the formwork! You’re in for a pleasant surprise here when you come to Doka’s expo pavilion at bauma 2010 – a pathbreaking wall-formwork innovation that slashes costs by needing fewer component parts and form-tie points.

Forming the clear typical zone and the difficult infill zones of floor-slabs equally quickly – can it be done? 3 m² of slab at one go? Working safely from floor level rather than performing acrobatics at dizzy heights? And all this with only minimal commissioning quantities? Doka will be revealing the answers to all these questions in its expo pavilion at bauma 2010.

In theory, of course, you could also double the load capacity by fitting two formwork beams side by side … if it weren’t for the problem with space, and with having twice the weight. Luckily, Doka now offers a trailblazing innovation that fits all Doka systems and that has twice the load capacity, despite having the same overall height and weight. Come and experience its world première in the Doka expo pavilion at bauma 2010.
