Pre-stressed elements are manufactured on casting beds upon mould sides are placed. Using a pre-stressing system, comprised of stressing heads and hydraulic tensioning equipment, a set of steel strands are pre-tensioned in order to manufacture stronger concrete pieces.
Casting beds are comprised of a supporting structure with several drill holes to fix the baseplates and fasten the mould sides.
The baseplates can be manufactured with several supporting positions in order to regulate the height and change the lower flange of the beams. In addition, the baseplates include sealing gaskets in order to ensure a perfect sealing of the mould.
The casting bed system can feature a heating system on the floor in order to accelerate the concrete hardening.
