It’s a modulated system of steel formworks designed for the production of precast box culverts and half-frames by using wet cast concrete.
The assembly and the opening of the mould are performed manually, joining the amount of necessary elements or modules in accordance to dimensions of the frame to produce. Depending on the supplied set of formwork, is possible to reach up to 7m in width (distance between the pillars of the box culvert). The same fixing system is used to add additional supplements to the outer mould. That allows adjusting the thickness of the precast box culverts.
When demolding the piece, it is possible to remove the inner and the outer mould in four parts each, what implies that they don´t have to be totally disassemble and simplifies the production process for series of pieces with the same measures.
