Anchoring auxiliaries –
Individual parts
Æ
Anchor holder
DW 15 – DW 26.5 (Fig. 20.1),
attachment to the upper rebar
layer. The use of the anchor
holder DW is recommended for
slab thicknesses greater than
approx. 40 cm or for slabs with
a large number and density of
rebars.
It is bent to 45° and can be
used with DW 15, DW 20 and
DW 26.5 tie rods. If the anchor
holder DW with anchor sleeve is
used, it can be used with tie rods
DW 15.
Æ
Single/double anchor DW,
attachment to the lower rebar
layer.
For slab thicknesses up to
approx. 40 cm we recommend
the use of single anchors
(Fig. 20.2) or double anchors
(Fig. 20.3).
Maximum loading:
Single anchor DW
DW 15 = 90 kN per tie rod
DW 20 = 160 kN per tie rod
DW 26.5 = 250 kN per tie rod
Double anchor DW
DW 15 = 180 kN
DW 20 = 320 kN
The single/double anchor is bent
to 45°.
Æ
The planing cap (Fig. 20.4)
with a 45° end face for use
with tie rods DW 15 and DW 20
(planing cap DW 26.5 for tie
rod DW 26.5) is made of rigid
foam and is inserted over the tie
rod or the anchor sleeve before
pouring, allowing a smooth,
level floor slab surface to be
achieved. Once the concrete has
been poured and the planing
cap removed, a coupling nut DW
can now be screwed onto the tie
rod and a second tie rod can be
installed to secure the support
frame.
Æ
Coupling nut (Fig. 20.5), to
enable the tie rods encased in
the floor slab to be extended.
The nut has a DW thread. Per-
missible load in KN and widths
across flats (WAF) in mm:
Ø 15: 90 kN, WAF 30
Ø 20: 160 kN, WAF 36
Ø 26.5: 250 kN, WAF 46
Æ
Fixed anchors DW 15,
DW 20 and DW 26,5 (Fig. 20.6),
to anchor the tie rods inserted
through the anchor holder DW.
