Precast concrete construction.

The best connections right from the start.

Industrially prefabricated concrete panel elements are manufactured to exact dimensions and largely automatically in a precast concrete facility. The high level of advance planning, industrial prefabrication in a controlled environment, and automation during production – particularly regarding the fixing and assembly of built-in components – ensure short installation times and minimised costs. Just as the manufacture of the elements is carried out with precision, so too must the components for the electrical installation be fixed and integrated into the wall or ceiling with the same precision.

Magnetic Retention System

Solutions for automated precast concrete production

  • The system-mounted magnet.

    One solution for all eventualities.
    The system magnets have set a new standard in automated precast concrete production for efficient manufacturing processes. This enables electrical installations to be implemented efficiently following digital planning (BIM) and thus integrated seamlessly into the precast concrete production process. With the new System Magnets (Art. no. 1299-69) or System Magnets PLUS (Art. no. 1299-70), the entire electrical installation can now be automatically integrated into the in-factory production process. Whether it’s B² one-gang junction boxes, wall and ceiling transitions, large slab ceiling boxes, or luminaire and loudspeaker housings, the new system magnets allow everything to be positioned securely and with millimetre precision. The new 48.5 mm extension element also enables the automated positioning and fixing of overhead electrical installations in solid concrete walls and double concrete walls.

    • The entire installation can be carried out using just one type of magnet – for automated placement (System magnet Art. no. 1299-69) or placement and removal (System magnet Plus Art. no. 1299-70)
    • Four lateral notches ensure that the one-gang boxes are installed without twisting
    • Holding force of 500 N
    • Reusable
  • Safe and quick connections using B² conduit connectors

    For horizontal precast concrete manufacturing
    The B² conduit connector range offers a secure, toolless conduit connection to the B² one-gang junction boxes, without the need for specialised tools. The conduit connection created using the conduit connector is completely sealed against concrete and reliably dampens conduit vibrations during the compaction process. As the conduit connection is made outside the B² one-gang junction boxes, no conduit protrudes into the interior of the boxes, thus eliminating the need to cut the conduit to length from the inside. With the new 90° conduit connectors, lateral conduit connections can now also be easily realised in confined installation spaces.

    • Toolless conduit connection; no specialised tools required
    • Exact ‘variable’ conduit connection, completely sealed against concrete
    • Damping of vibrations during the high- or low-frequency compaction process
    • Conduit connection outside the one-gang junction box; no conduits protruding into the interior of the box
    • 90° conduit connectors for the lateral connection of conduits in confined installation spaces

Concrete construction – For on-site mixed and precast concrete

  • Central transition casing.

    For universal conduit entries.
    The new central transition casing, designed for use in in-situ concrete slabs or precast ceilings, is used to bring together conduits of different diameters at a central point. As a central feed-in point, it provides a neat transition to circuit distribution boards and cable routing systems; for example, all the supply cables required for the electrical installation of a flat can be brought together at a single transition point. For routing multiple electric cables, e.g. above an electrical distribution board recessed into a lightweight wall or surface-mounted

    • For routing multiple electric cables, e.g. above an electrical distribution board installed in a lightweight wall or surface-mounted
    • For system magnets, adhesive or nailing fixings
    • Conduit entries for Ø 20 mm, Ø 25 mm and Ø 32 mm on the long sides; up to Ø 63 mm on the short sides
    • Positioning of the conduit entries above the first layer of reinforcement or the top surface of the filigree ceiling
    • Can be joined together as often as required
