Underfloor systems

Mounting aid, underfloor duct

Draw mounting planning

The planned duct routes and the crossing points and points relevant for junction and branch boxes or underfloor boxes should be marked on the floor in advance, e.g. using a chalk line.

Mounting of underfloor boxes

Underfloor boxes are aligned and fastened on the lines and the crossing points. This allows the required duct length to be determined.

Preparations for trunking installation

The length of the duct sections can now be determined exactly. The material can be laid out on the floor.

Cutting the ducts

The simplest way to adjust the sheet steel ducts is using a single-handed angle grinder. Clean cuts and subsequent deburring are important for beneficial installation of the cables.

Duct connector mounting

The duct connectors can be positioned after the duct has been cut to size.

Equipotential bonding

Connection shackles create the conductive connection of the two inserted pieces of duct. Alternatively, conductive connections can be created between construction elements using external connections, by soldering, welding, riveting or screwing.

Connector fixing

The underfloor duct is fastened to the substrate using the connection shackle. Additional fastening within a duct length is not required.

Mounting, riser bend

Riser bends can be easily mounted as wall connections for insertion of cables in the underfloor system. The connection is simple to make and uses a duct connector.

End cap mounting

The underfloor duct is closed with an end closure section, suitable for each duct size. The end connection can simply be inserted into the duct without any screwing.

Prefabricated duct mounting

This means that the cable routing system has been laid. The cables can be laid before the screed is applied (except for poured asphalt) or after the screed is applied, as for any installation at a later date.
