PRECAST CONCRETE ELEMENTS170 CPI %u2013 Concrete Plant International %u2013 5 | 2025 www.cpi-worldwide.comFormwork for stairs is experiencing a boom in the residential sector thanks to its quality, adaptability to any construction context and cost saving. Olmet Italy, committed to offering its customers the most suitable solutions for their needs, focuses on the versatility of its formwork. To this end, the company continues to expand its range of moulds designed to produce prefabricated staircases.Olmet offers different configurations of formwork for stairs: with or without landings, with adjustable or fixed risers and treads.These formworks can be manufactured with casting in horizontal position but also in vertical position (battery formworks for vertical casting or single formworks for horizontal production).The battery formwork can be supplied with fixed section, to produce a large quantity of elements and to optimize production processes.Olmet also supplies double batteries with the possibility of adjusting all the geometric dimensions of the stair, such as:%u2022 tread length%u2022 tread thickness%u2022 number of the steps%u2022 thickness of the concrete element%u2022 length and width of the landing%u2022 thickness of the landingThe adjustment of the lift and the tread is performed by means of screw kinematic mechanisms. To facilitate the demoulding of the concrete elements, the sides can be moved laterally by using hydraulic actuators, or, as an economic alternative, with mechanical levers.The formwork can be supplied together with an integrated heating system, that uses water, diathermic oil or steam as the heating agent. An electric resistance heating system can also be used. In the customer doesn%u2019t use SCC concrete (self-compacting), high-frequency electric vibrators or pneumatic vibrators can be installed on the equipment table. The opening and closing handling operations of the side elements, any other automated handling operations and the management of the vibration cycles can be managed using HMI controls. The main advantage of these types of adjustable moulds is that different types of staircases can be made with the same mould, saving time and money, as well as being easy to use.New project in PolandRecently the company has manufactured two vertical formworks for the Polish market. The element is cast vertically. This is to achieve a smooth finish on both sides of the element.Technical data:%u2022 maximum element width: 1.800 mm%u2022 number of steps: 20%u2022 landing length: right and left x 2.000 mm%u2022 electro-hydraulic adjustmentsAdjustable mould for manufacturing concrete stairsOlmet Italy, 31040 Signoressa di Trevignano (TV), ItalyTwo vertical formworks to manufacture staircase elements
