PreconditionsPlanning an preperation
As for all projects, success depends on good planning. Choosing to use sliding formwork for construction early in the planning process means that the project can be prepared for this technique. Important parameters such as concrete quality must be checked. Unintended variations in the concrete quality must be avoided, and efficient, accurate control of the concrete setting time is particularly important. Moreover, reinforcement should be standardised with as few posts as possible, and particular attention must be paid to the distance between the reinforcement bars, bar length and the shape of angles and bows. If required, tensioning cables are fitted simultaneously with the other work, so stringent requirements apply to pre-positioning and preparation. Openings and embedded items must also be adapted to the sliding casting method, as such items must not extend beyond the wall surface of the construction. Normally, such items need to be 15-20 mm thinner than the wall(s) in question. Sliding profiles with the correct contour height and position need to be prepared.
It is just as important to recognise that a sliding operation is a team effort, where the slide is in continuous motion, and where parties other than Interform are involved in casting, reinforcement, positioning of openings, cleaning etc.
