faster forming witout spacer tubes and anchor cones
The cellar of the Rettenberg single-family house was realised on an incline with 25 cm thick reinforced concrete walls and formed in two concreing cycles. For this, the locally-based building contractor used
the MAXIMO panel formwork system for the first time. PERI engineers planned the use of the MAXIMO so that a well-balanced element confi guration was achieved not only for both cycles but also for subsequent
projects.
A PERI sales engineer was on-site to give important tips regarding the optimal use of the formwork system as this was the first time that the small construction team had used MAXIMO. The difference to conventional panel formwork: the rigid external corner and, in particular, the MX tie which is installed from one side only.
This meant that spacer tubes and cones were unnecessary so that formworking operations were significantly accelerated from the very beginning. Panel connections were carried out using the proven BFD alignment coupler which also bridged timber infi lls up to 10 cm wide requiring only one connecting part.
The construction crew used the stopend panel for the continuous reinforcement in the transition area between the first and second cycles. In addition, the MAXIMO tension and compression brace provided simple and safe load transfer where individual tie points in the upper row were not used. Especially with foundations, parapets and beams - those situations where MAXIMO panels are used horizontally - this has enormous advantages in connection with the centrically-positioned tie points.
"If we purchase something, then only the very latest. And the MAXIMO with the tie installed from one side only is indeed progress. The centric tie points
are also a big advantage for foundations as no timbers are required. The rigid external corner is good as well.”
