Connecting steel profile rail sections

 

Depending on the length of the individual profile rail sections, the number of suspensions, the on-site building conditions and the length of the crane track, several profile rail sections should be connected with each other on the floor if possible.

The connected profile rail sections must be able to be raised and brought underneath the suspensions safely and without posing additional hazards.

If this is not possible, the profile rail sections must first be fixed individually or as sections on the suspension and then afterward fully joined with each other. When doing this, it must be ensured that there is adequate space underneath the suspensions, especially in the case of short suspensions.

 

Baugröße

The figures show the installation of an HB profile rail of size HB150S. The installation of larger or smaller HB profile rails does not differ significantly from this.

 

 

Laying out the profile rail sections

*  The profile rail sections must be laid out on the building floor the way they are to be later installed.

Planungsunterlagen

The position of the profile rail sections is specified in the planning documents.

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

 

 

Removing the protective film

The profile rail sections are laminated at the sides. The protective film is removed before further assembly.

 

 

Protective film

*  Pull off the protective film at a sharp angle from the side lamination.

 

 

Combining profile rail sections

At each profile joint:

Profile rail sections

 

*  Turn the profile rail sections so that the arrows on all of them point in the same direction.

*  Place the profile rail sections flush to one another.

The profile rail sections can be directly flush to one another. The must not be more than 2 mm apart.

 

 

*  Raise the profile rail sections just in front of the profile joint by about 5 cm (e.g. on the floor with a wooden beam or, with suspended assembly, by slightly lowering the unassembled profile rail section).

●   In this way, the profile rail sections join at a slight angle to one another. This ensures that despite the camber (the profile rail sections are arched upward slightly) the distance at the bottom between the profile rails is as small as possible.

 

 

Inserting the spacer parts

Profile rail section

Spacer part

*  Insert spacer parts from above in the left and right profile rail sections and, if necessary, knock them slightly into place.

●   The spacer parts are clamped in the profile head but can still slide back and forth.

 

 

Inserting the clamping plate

Only with HB240

 

There are two different clamping plates available (with brackets or joining rib).

Planungsunterlagen

Which profile joint is to be mounted on which clamping plate is specified in the planning documents.

 

─     If the distance from a suspension to the profile joint is maximally 600 mm, use the clamping plate with brackets (length 700 mm):

Distance maximally 600 mm

─     If the distance from a suspension to the profile joint is greater than 600 mm, use the clamping plate with joining rib (length 1100 mm):

Distance greater than 600 mm

 

 

Baugröße

The figures show the installation of a clamping plate with brackets. The installation of a clamping plate with joining ribs does not essentially differ.

 

 

 

 

 

Clamping plate

*  Tilt the clamping plate slightly and insert it below in the profile rail section.

When doing this, insert the bottom of the clamping plate behind the edge on the profile rail section.

*  Position the clamping plate so that it is exactly centred between the two profile rail sections.

*  Press the top of the clamping plate against the profile rail section.

 

 

Bolting on the assembly aid

An assembly aid can now be bolted on at the top. It will make it easier to screw the clamping plates together.

 

On the clamping plate:

Assembly aid

Rib nut M12

*  Bolt the assembly aid on the outer lug with an M12 rib nut.

●   The clamping plate is held by the assembly aid and can no longer fall down.

 

 

Bolting on a second clamping plate

*  Insert the second clamping plate as described above on the opposite side and secure it with the assembly aid.

 

Only with a craneway suspension in the area of a clamping plate

This work step only applies if a suspension will be installed in the area of a profile joint.

 

Inserting the profile link

After both clamping plates have been inserted and secured with the assembly aids:

 

Baugröße

The figures show the installation of an M16 profile connection. The installation of an M20 profile connection does not essentially differ.

 

 

 

Bearing shell

 

 

Profile link

 

*  Tilt the profile link and insert it from above at the required point in the profile head.

Once the clamping plate is installed, the profile link can no longer be shifted to a different lug.

The bearing shell in the ceiling-mounted bracket and on the profile link must always have the same colouring (silver or yellowish). Ceiling-mounted brackets and profile links with differently coloured bearing shells must not be installed together.

* Turn the profile link 90 degrees.

 

 

Positioning the clamping plate

Only with a craneway suspension in the area of a clamping plate: the clamping plates do not need to be inserted exactly centred on the profile joint. The clamping plates can be shifted up to 100 mm to the left or right so that the profile link for the suspension is always at the preferred point.

 

Note:

For a profile joint without a suspension, the clamping plates must be installed exactly centred!

 

*  Only with a craneway suspension in the area of a clamping plate: the clamping plates can be shifted up to 100 mm.

 

 

 

 

Screwing in the assembly screw

The assembly screw (which is longer than the actual screws) is used to pull the clamping plates to the HB profile rail so that the actual screws can be inserted.

 

*  Check the spacing of the profile rail sections again.

The profile rail sections can be directly flush to one another. The must not be more than 2 mm apart.

 

 

Assembly aids

 

 

Assembly screw M12x95

*  Insert the M12x95 assembly screw through two opposite-lying brackets of the clamping plate.

*  Screw a hexagonal nut onto the assembly screw.

*  Continue screwing the assembly screw and hexagonal nut together to pull the clamping plates to the HB profile rail from both sides.

*  Once the assembly screw is screwed on: remove the assembly aids (2x).

 

 

Screwing the clamping plates tight

On all spacer parts:

Assembly screw

Hexagonal nut

Cup square bolt

Spring washer

*  Push the cup square bolts through the clamping plates and the spacer parts.

●   The square end of the cup square bolt locks in the clamping plate and therefore cannot turn.

*  Insert spring washer.

*  Loosely screw the M12 hexagonal nut onto the cup square bolt.

*  Screw the hexagonal nuts on. 120 Nm.

 

The U-shaped plates included do not have to be installed yet. They are only required if the travel gap is too wide.

 

 

Checking the travel gap and distance apart

After the assembly of the clamping plates, check whether the profile rail sections have bent apart.

 

 

Travel gap

 

Distance

*  Check the travel gap in the area of the profile joint:

─     The travel gap is permitted to be maximally 25 mm wide.

─     The travel gap must be at least 19 mm wide.

*  If the travel gap is too wide or too narrow: press the profile rail section together with a screw clamp or use a suitable lever to press it apart.

*  Check the spacing of the profile rail sections.

The profile rail sections can be directly flush to one another. The must not be more than 2 mm apart.

 

 

Only with HB110, HB150 and HB190

 

If the travel gap is still wider than 25 mm:

 

The enclosed U-shaped plates can be inserted in addition to the spacer parts to reduce the travel gap.

 

 

Spacer part

U-shaped plates

Clamping plate

*  Slightly loosen all hexagonal nuts on the cup square bolts.

●   The clamping plates (2x) move apart at the top at the spacer parts.

*  Insert a U-shaped plate from above on the left and right next to all spacer parts.

The plates always have to be inserted on the left and right and always on all four spacer parts.

The plates must be inserted until they are flush with the top edge of the spacer parts.

*  Screw the hexagonal nuts on. 120 Nm.

●   The plates keep the clamping plates on the profile head somewhat further apart. Thus the profile rail sections at the travel gap will not bend as far apart.

*  Check the travel gap again.
