Two ROBUD stripping corners are mounted on the inner part of elevator shaft diagonally. Before concreting the corner is installed to standing position by turning the spanner. The sides of the angle in this position will make *5 cm.

After concreting and concrete setting, the span is turned to the opposite direction of **0 °, sides of the angle come inside for 1,5 cm each thus reducing the size of each side of the formwork rectangle. Formwork tears of the concrete and can be extracted by the crane without dismantling by one piece. Such design is proved on practice to be easy, reliable and convenient in use.
Efficiency
- Reduce wearing of the formwork while dismantling; - Reduced labor costs and construction time; - Saving crane time; - Only 2 stripping corners are needed for the dismantling of the elevator shaft; - Possibility to use the corners not only for elevator shafts dismantling but also for large stairwells.
