CRH Leviat Ancon 2000 Installation Manual

Ancon 2000 Thin Facing Restraint
Restraint fixing for connecting thin facing slabs back to a structure

Installation Procedure


Mark out hole location for expansion anchor – typically this will be 13mm above the centre of the horizontal joint in the
facing slab to be restrained.

Drill Ø12 x 85mm hole using hammer drilling & clean hole using blow
pump.

Insert expansion anchor until it is flush with the outer face of the concrete.

Tighten anchor using the hexagon bit supplied. Correct installation is
reached at either 15Nm setting torque or when the gap between face of
concrete and outer face of expansion bolt reaches 3 – 5mm (dimension
'U' shown opposite).

Insert M6 threaded stud into internally threaded expansion anchor. The
exact screw-in depth for the stud will depend on the cavity dimension but
should not be less than 16mm. Note, positioning a nut approximately
25mm from the end of the stud before screwing it into the expansion
anchor can speed up the next step.

Fasten a single nut on the stud so the nut is in contact with the concrete face. Assemble the fixing clip in the desired
positon using the remaining 2 No. nuts.

At this point, for smaller cavities, the studding may require cutting back to avoid a clash with the facing slab.

Lay facing slab and use a Ø4 x 60mm loose dowel inserted through the fixing clip to provide restraint. Ø4.5 x 30mm holes
should be provided in the facing slab.

Adjustment is provided by the horizontal and vertical slots in the fixing clip and fine cavity adjustment can be achieved by
moving the fixing clip along the length of studding.
Installation Guide
The Ancon 2000 is designed to restrain thin facing slabs, such
as natural stonework, and provides a secure fixing in the
structural frame thanks to the expansion anchor. The restraint
comprises an M12 expansion anchor with internal thread to suit
an M6 threaded stud, a fixing clip and loose Ø4 x 60mm dowel
pin.
The Ancon 2000 can be manufactured to suit facing thicknesses
of between 20 and 40mm and can accommodate cavity sizes up
to 180mm. It is suitable for use in cracked or uncracked
concrete. For other substrates e.g. blockwork or steel, please
refer to Leviat's Technical team.
