Concrete formwork engineers and manufacturers continue to orient their systems to construction speed and contractor profitability. Messe München, manager of the bauma 2016 trade fair, April 11-17 in Munich, cites examples of exhibitors’ new and upgraded forming equipment and technology: A new development from Peri, a formwork and scaffolding technology company based in Weissenhorn, Germany, is aimed at foreign markets with a colder climate. Peri combined its proven Maximo wall formwork system with optional, easy-to-mount heating modules. Heating ensures that concreting work can be carried out even at low temperatures since the hydration process is not inhibited. Another Peri innovation set for Munich is an automatic climbing system especially designed for high-rise building cores with medium to large dimensions. New hydraulic units supply the power to climbing hydraulic cylinders, which produce a hoisting capacity of 40 tons. Due to this high load-bearing capacity, large concrete placing booms can also be raised and supported during operation.
One key factor in concrete construction efficiency is an optimal formwork removal schedule. Doka, a formwork specialist from Austria, offers the Concremote service for this purpose. The development of the compressive strength and hydration heat of the concrete during construction is measured in real time in this respect. Formwork removal times, after-treatment times, and the earliest point for prestressing can be derived from concrete strength development readings. Doka will present a further development at bauma: The “Concremote plug.In,” integrated directly in the ceiling system of the formwork and automatically providing information on the correct time for formwork removal.
Speed is also vital in many regions of Latin America, Southeast Asia and the Middle East, especially when inexpensive housing is required. Doka has developed OneGo, a monolithic formwork system, as a solution to this challenge. In this system, which will be presented during bauma, walls and ceilings are concreted in one cast. According to the company, the application area of Doka OneGo ranges from single-family houses and apartment complexes through to multi-story buildings.
Friedr. Ischebeck GmbH of Ennepetal, Germany, will present a new 30-kN prop with an external aluminum tube and a tubular steel threaded spindle. The special aspect of this prop is a quick adjustment nut normally found in steel props. Thanks to the special external aluminum tube profile, the new prop also features the option of elevation and reinforcement with aluminum stiffening frames.
Based on the model in other industries, the construction industry is also increasingly striving to create a chain from planning and construction through to the operation of buildings. The key phrase here is Building Information Modeling (BIM). Steinach, Germany, manufacturer Paschal is heading in this direction with its already tested formwork software Paschal-Plan light (PPL). It supports the planning and implementation process for concrete structures throughout the entire construction period.
According to the company, the practical experience of Paschal itself and many other users has been included in the adapted version that will be presented at bauma. One new feature is the “ceiling formwork” module; in-situ concrete ceiling formwork and filigree ceiling supports can be produced automatically. The shoring system is also dimensioned based on the calculation in DIN EN 12812. According to Paschal, 3D models can be produced quickly and easily using the “Design” module. With just one click, users can generate a cross-system material list from the parameters in the 3D model. The “Warehouse” model can be used to administer the entire stock of formwork and machines transparently—on both a building site and in a building yard.
INNOVATION AWARD NOMINEES
Messe München GmbH has announced 15 bauma Innovation Award nominees. Winners will be honored the evening of April 10, ahead of the trade fair opening the following day, in a ceremony at the Allerheiligen Hofkirche (Court Church of All Saints) in the Munich Residenz. bauma opens its doors from April 11 to 17 at the Messe München exhibition center.
The Innovation Award is presented in five categories: Machinery; Components; Construction Process/Construction Work; Research; and Design. In total 118 applications were received from Germany and abroad. The jury has selected three new developments in each category for a final judging round. Beyond sustainable attributes, Messe München notes, all of the nominated innovations offer significant practical benefit and economic potential, and make a contribution toward energy- and resource-efficiency and/or toward workplace humanization.
