Information graphic - MAX FRANK offers a comprehensive range of distance tubes with suitable sealing options for their openings in the concrete wall. We give an overview of the sealing variants of tie holes.
Sheet piles are used as permanent or temporary support of excavations. Pecafil® formwork acts as a sacrificial back shutter for the concrete liner wall, the sheet piles are spanned and do not need to be filled with concrete.
For the "Stuttgart 21" traffic construction project, chalice-shaped pillars are being built for the roof of the main railway station. In order to ensure compliance with the concrete covering, spacers made of fibre concrete are used on the reinforcement of the columns.
The requirements for shuttered fair-faced concrete surfaces are particularly high for representative structural elements in building construction. For this purpose, spacers with a minimum contact area are recommended in order to avoid marking the contact points.
Whether for force transmission, sealing or special component geometries – there is a great deal of variation in the execution of expansion joints. For that reason, the manufacture of this formwork on the building site is often complex, unreliable and time-consuming.
