The comprehensive renovation of a 42 metre high residential building in Schützenstraße in Innsbruck has been successfully completed. One of the biggest challenges of the project was to provide the residents with safe and easy access to their flats throughout the construction period.
Norm-compliant tower
The scaffolding company Roman Mair & Söhne GmbH chose a 42 metre high scaffolding tower from RINGER as the solution. This served as a temporary staircase and met the required safety and comfort standards. The Public stair tower fulfils all the necessary regulations, including the standards applicable to public areas such as ÖNORM B5371 and OIB Guideline 4.
The key points included:
> Passage width of 1.2 m
> Special gradient level, step heights and tread widths
> Closed railings and own handrail
> High load-bearing capacity for daily party traffic
Thanks to the flexibility of the RINGER modular scaffolding, these requirements could be realised without any problems.
The enormous height of the building required the construction of one of the tallest scaffolding towers ever erected in Tyrol. The construction comprised 14 floors consisting of a total of 28 scaffolding levels (each 1.5 metres high).
The modular design of the RINGER modular scaffolding and the extensive expertise of the RINGER scaffolding specialists enabled a large number of special solutions.
Individual exits had to be planned for each floor of the building, which involved a considerable amount of planning and a high degree of precision.
A key part of the project was a customised calculation of the statics, which ensured that the stair tower offered maximum stability and safety even at a height of 42 metres. Not only did the structural requirements of the construction itself have to be taken into account, but also the dynamic loads caused by the residents' daily traffic.
In addition, special transition elements were developed to allow smooth access between the individual floors without compromising the stability of the overall system.
Efficient technology for demanding projects
The RINGER modular scaffolding impresses with numerous features that have been specially developed for demanding projects such as this one:
> Durability thanks to full galvanisation
> Steel decks with loads of up to 600 kg/m²
> Time-saving assembly thanks to clever wedge connections
> Low transport and storage costs
For the actual renovation work, the customer's own RINGER speedy-scaffolding was also used, which is characterised by its ease of use and efficiency.
The scaffolding systems from RINGER have a decisive advantage: they combine maximum flexibility and efficiency with the necessary safety standards, thus enabling complex projects to be realised economically and smoothly.
