In the middle of March 2019, RATEC was again commissioned to design and construct a shuttering solution for transformer station modules.
This module mould is also designed to be highly variable, similar to its predecessors. It can be used for the production of two stations with two different external width (3.10 and 3.60 metres) and exterior heights (2.59 and 2.84 metres), while the exterior width is a uniform 2.41 metres. The length is variable by means of a fitting element, which is mounted between the two core halves. The height is realised using extendable floor moulds.
Compared with the predecessor project, fewer individual attachments are used for this mould. Only the inner walls of the stations vary, which are produced with the help of specially tailored inserts for the core. In total, the customer can use two times three interchangeable inserts for his station variants, which are inserted by crane and hydraulically tensioned afterwards. This means that less effort is required when changing attachments with this type of mould compared to the initial type. But this always depends largely on the number of station types that are to be produced with a mould. Together with the two length and height options, the mould enables a total of twelve different station variants.
A stripping slope is provided here as well, which means that the walls are slightly conical. For lifting, the floor mould is raised hydraulically by around ten centimetres. The floor mould has a total lifting force of 60 tons, spread over four cylinders. This mould is also equipped with vibrators, which are used for normal and washed concrete and introduce 14 kilonewtons of vibrating force.
A subsequent order again confirmed the customers’ high confidence in RATEC's expertise and the reliability of a high-quality product “Made in Germany”, which mirrors the dimensional accuracy and longevity of the mould.
