Installing the ceiling-mounted bracket 2LP/M16 : Anchor bar (Halfen channel)

The ceiling-mounted bracket 2LP/M16 is bolted onto an anchor bar made by the Halfen company, which has been firmly cast in the concrete element.

Only one 2LP/M16 ceiling-mounted bracket can be installed on a cast anchor rod on a ceiling connection. A 2LP/M20 or 4LP/M20 ceiling-mounted bracket cannot be installed.

The figures show the installation of a ceiling-mounted bracket 2LP/M16 or M20 with projecting threaded rod (with normal suspension, short suspension and normal stiffener). The installation of a ceiling-mounted bracket 2LP/M16 with bolted-on articulated girder (with normal stiffener, inclined suspension, inclined stiffener and V-suspension) does not differ significantly from this.

Casting the Halfen channel in the concrete element

When casting the concrete element:

Planungsunterlagen

Where and at what intervals the Halfen channels are cast is specified in the planning documents.

The specified dimensions, positions and clearances must be followed exactly.

─ Only use anchor bars manufactured by the Halfen company that have been approved by building inspectors and are suitable for dynamic loads.

─ Follow the instructions of the manufacturer.

─ Only use parts of the Halfen channel system that are designed for one another.

Later-installed HB profile rail	Suspension distance LB

Align the Halfen channel so that the ceiling-mounted bracket will later be lengthwise exactly perpendicular to the later-installed HB profile rail.

Position the Halfen channel so that the ceiling-mounted bracket will later be exactly centred in relation to the later-installed HB profile rail.

This is necessary so that the HB profile rail can later be aligned.

Take the Halfen channel into account when planning the reinforcement and concrete covering.

Installing the threaded plate

On every ceiling-mounted bracket 2LP/M16:

Halfen channel

Halfen screw

Insert the Halfen screws (2x) in the Halfen channel while turning them.

Position the Halfen screws so that they fit the hole spacing of the threaded plate.

Threaded plate	Square washer

	Halfen screw

Insert square washers (2x) on the Halfen screws.

The threaded plate must lie flat against the Halfen channel. It should not lie on the concrete around the Halfen channel. The square washer ensures that the threaded plate lies against the Halfen channel and does not strain the concrete.

Insert the threaded plate on the Halfen screws.

Washer

Hexagonal nut	Lock nut

Screw on washers (2x) and hexagonal nuts (2x) on the Halfen channel.

Screw on hexagonal nut.

Halfen screw	Size, length and rating	Tightening torque
HSR40/22	M16x40 (8.8)	200 Nm
HSR 50/30	M20x45 (8.8)	400 Nm
HS 50/30	M24x45 (4.6)	200 Nm
HS 72/48	M24x45 (8.8)	680 Nm

Tightening torque for Halfen screws.

Screw on lock nuts (2x) and counter them.

Bolting the ceiling-mounted bracket 2LP/M16 to the threaded plate

Only with ceiling-mounted bracket 2LP/M16 with articulated girder

This section only applies to the ceiling-mounted bracket 2LP/M16 with bolted-on articulated girder (with normal stiffener, inclined suspension, inclined stiffener and V-suspension)

Turning the articulated girder

On every ceiling-mounted bracket 2LP/M16 with articulated girder:

The articulated girders can be mounted lengthwise or crosswise to the ceiling-mounted bracket 4LP/M20 as appropriate for the alignment of the supporting structure.

	Articulated girder

Insert M16x35 rib screw through articulated girder.

Insert articulated girder with rib screw in ceiling-mounted bracket.

Screw the M16 rib nut loosely onto the rib screw from the back.

Shift the articulated girder lengthwise or crosswise to the ceiling-mounted bracket as necessary.

Screw the rib nut on. 300 Nm.

On every ceiling-mounted bracket 2LP/M16:

	Clamping plate

Ceiling-mounted bracket	Rib screw M16x70

Hold the ceiling-mounted bracket (1x) and the clamping plates (2x) against the threaded plate from below.

Loosely screw on the ceiling-mounted bracket with the M16x70 rib screws (2x).

Position the ceiling-mounted bracket so that it is exactly centred in relation to the later-installed HB profile rail.

This is necessary so that the HB profile rail can later be aligned.

First, screw in M16x70 rib screws (2x) until hand-tight.

The rib screws will later be tightened to the correct torque (after aligning the HB profile rail).

If final alignment of the ceiling-mounted bracket 2LP/M16 can now be done:

Screw in rib screws. 200 Nm.
