Automated production of thermal walls for energy-efficient construction with iglidur® PRT slewing ring bearings

Profile

• What was needed: slewing ring bearings with outer drive ring, xiros® conveyor roller, a stepper motor with encoder and brake as drive in addition to a harnessed igus® readychain® and an energy chain from the E4.56 series
• Requirements: withstanding high dirt loads for angled cuts in building materials
• Industry: construction/mechanical and plant engineering
• Success for the customer: automatic insulation material cutter that crops the insulation panels according to the CAD data

EBAWE Anlagentechnik GmbH from Eilenburg in Saxony - a company for mechanical and plant engineering and manufacturer of turnkey production plants for the precast concrete industry, was looking for a special solution for which igus® provided advice. 
A customer from the USA wanted to insert the so-called thermopins (used to connect the facing and supporting shell of core-insulated prefabricated concrete parts) not only perpendicular to the insulation board, but also diagonally in any direction. Therefore, a 3D head had to be developed to attach the high-pressure water jet nozzle, which enables these oblique cuts.

The development of a 3D head that makes angled cuts and holes using a high-pressure water jet. 
The bearings of the 3D head's axis are realised with iglidur® slewing ring bearings (type PRT-01). 
The insulation is then attached to the inner shell of the thermal wall with the thermopins. The insulation material is placed on the still liquid concrete of the inner shell, which has just been cast. The thermopins are inserted into the liquid concrete through the holes created by the automatic insulation material cutter. Once the concrete has hardened, the insulation holds securely to the inner shell.
