The basics
On the basis of construction drawings, we plan the performance of sliding formwork with drawings and slide profiles for openings and embedded items. The moulds, which are 1.1 metres high, are made of wood covered with a 1 mm steel sheet. According to the load and design in question, we fit lifting yokes and hydraulic jacks. The jacks are fitted to scaffolding that is gradually moved as the slide progresses. Lasers are used for vertical checking, while spirit levels are used for horizontal checks. The work platform itself is fitted to beams with a hanging platform mounted below. During operation, all the jacks are controlled by a central unit. Each lift normally raises the slide 20-25 mm. Casting and reinforcement work is normally performed continuously as the sliding formwork works its way up. The intended hardening front is approximately 90 cm, which means that this is located around 20 cm from the bottom edge of the mould. The setting time is regulated by additives (acceleration/retardation) so that it matches the progress of the mould.
The normal slide rate is 2.5-3.5 metres per day, but depending on the construction project, we can produce 7-8 metres per day.
