The training at a glance
Precast concrete builders produce weights, ballast and other concrete products from concrete and heavy concrete.
For the different weights, they use ready-made molds or assemble molds and formwork from multiplex panels, squared timber, GRP, polyurea and other formwork material. In doing so, they follow the design drawings and plans exactly to install the end product at the specified location.
In series production, prefabricated reinforcement cages are placed in the molds.
If you manufacture individual concrete products, e.g. weights for special machine construction, you build in reinforcement made of steel rods and iron mesh for static reasons
With the help of machines, precast concrete part builders shorten steel rods, bend them into shape according to specified plans and then join them together with binding wire. They anchor the reinforcement in the concrete formwork. Now the concrete mix can be placed.
They compact the liquid concrete with formwork vibrators and give it an even surface with trowels and smoothing boards. If necessary, they treat the finished parts after hardening with grinding machines. This also requires a certain design skill.
Precast concrete workers transport the finished concrete products to the storage or loading area using hoists or transport equipment. If necessary, they also monitor the loading of the finished parts onto trucks.
