Form/Moulds for stairs

Bianchi Casseforme specializes in the production of fixed and adjustable formwork for precast stairs . The staircase is in fact a precast element that can be completely variable in all its dimensions.

When it is necessary to produce many elements with the same riser and tread dimensions, the best solution is that of a fixed formwork. On the other hand, when it is necessary to produce stairs of always different sizes, the optimal solution is to use a flexible formwork.

Formwork for Stairs

Considering the casting from a vertical position (to have the best finish on both the upper and lower part of the element) in the first case the stair formwork (Fixed) will be composed of a base frame, 2 lateral sides (one smooth with the shape of the lower part of the stairs and another with folded sheets that replicate the different steps) and at the two ends of the banks there is the equipment for the landing.

The sides are fixed to the base frame and can be opened manually with a quick release.

The base can be raised by means of a telescopic support, thus adjusting the width of the staircase, while the number of steps and landings can be changed simply by moving the side separators.

In the event that the formwork is too high and access from the ground is difficult, access stairs and walkways are provided.

In the second case (Flexible Formwork) the base can be adjusted in height, the smooth side panel can be opened and closed hydraulically, while the edge that replicates the shape of the steps has a fixed position but the riser and tread measurements can be changed. Side rails can include magnetic triangular bevel in variable position connections. The step adjustment can be done manually or hydraulically with a pantograph system. The sides for the landings can be positioned in different ways, depending on the number of steps the staircase requires.

These formworks can be equipped with a vibration system, which compacts the concrete by removing the air, thus improving its resistance.

The presence of a curing plant increases productivity by reducing the curing time of the concrete.
