Meva STB Series Owner's manual

Technical Instruction Manual
Support Frame STB

The support frame is mainly used for pouring against existing struc-
tures (walls, rock, soil, sheet piling, foundations, etc.) if only one side
of the formwork can be erected. For practical reasons it is generally
not possible to tie through the formwork. Hence, the total fresh-con-
crete pressure has to be transferred via the formwork into the support
frame and then on into the foundation. The MEVA support frame
consists of a welded and painted steel construction.
See the separate STB load charts for details about the loads that occur
in standard applications.
Permissible anchor loads according to DIN 18216
Anchor system Permissible loading
DW 15 90 kN per tie rod
DW 20 160 kN per tie rod
DW 26.5 250 kN per tie rod
When using the support frames, special attention must be paid to the
following:
ÆThe foundations and floor slabs, etc. must be able to withstand
the tensile and compressive forces that occur. A structural verification
may be required.
ÆThe "opposite side" of the single-sided formwork, i.e. the exist-
ing structure, must also be able to resist the fresh-concrete pressure.
ÆThe DW tie rods must not be welded, heated or deformed.
ÆFor more complex or special cases not dealt with in this manual
please contact the MEVA experts for advice.
ÆDeviations from the versions described in this manual always
require a separate structural verification.
Attention
Check on-site to make sure that the tensile forces Z and the compres-
sive forces V that occur can be safely transferred into the foundation
or floor slab. In particular, the concrete strength and the degree of
reinforcement used need to be reviewed. If the support frames are
used on top of slabs – for example in underground garages – support
the slab where the vertical forces V occur in order to transfer these
into the foundation.
Abbreviations, measurements, figures and tables, etc.
The abbreviation STB is used for the support frame. DIN means
Deutsche Industrie-Norm (German Industrial Standard). E DIN (E =
Entwurf / draft) means that the DIN is in draft status and not yet
approved. Any further abbreviations are explained where they are
used for the first time.
TÜV means Technischer Überwachungsverein. This is the independ-
ent German organisation that tests the safety of technical installa-
tions, machinery and motor vehicles. If a product passes the test, it
is permitted to carry the GS seal. GS stands for Geprüfte Sicherheit
(approved safety).
Measurements: This manual uses the metric system, i.e. m (for metre),
cm (for centimetre) and mm (for millimetre).
Non-defined dimensions are in cm.
The page numbers in this manual start with STB. The figures and
tables are numbered per page. Depending on its product abbrevia-
tion, a cross reference in the text refers to a page, table or figure in
this or in another manual. This is indicated by the product code with
which the cross-reference begins.

STBSupport frame

The STBsupport frames and the
brace brackets can be combined
with all MEVA wall formwork
systems as well as with special
designs.
From a structural and economic
point of view and depending
on the formwork system used,
it may be more advantageous
to use the support frame with
vertical (Fig.5.1) or horizontal
panels (Fig.5.2).
The support frame can be
attached to the MEVA wall form-
work panel from the frame side
with flange screw18 (Fig.5.3).
Alternatively, it can be attached
from the facing side using fixing
screw35 and articulated flange
nut15/120 or flange nut100
(Figures5.4 and 5.5).
Attention
ÆWhen using the STB unit
vertically, the spindle must be
set to the middle position before
mounting the STB on the form-
work. This ensures that it can
be perfectly adapted to suit the
supporting surface.
ÆRefer to the product list for
the spindle stroke.
ÆBefore pouring, ensure that
all STB spindles and additional
braces are secure and contact
the ground.

Pre-assembly of support frame units
The surface on which the form-
work and the support frames are
pre-assembled should be clean,
even and capable of supporting
the total weight. The support
frames are attached to the rear
of the horizontal formwork
panels (Fig.12.1).
Assembly
ÆThe support frame is
attached to the formwork’s mul-
ti-function profiles using flange
screw18. Alternatively, it can
be attached using the tie holes
of the formwork with fixing
screws35 and articulated flange
nuts15/120 or flange nuts100.
The fixing screws must be in-
serted through the tie holes and
secured to prevent them falling
out, using the flange nut100 for
example, before the formwork
panel is placed on the ground.
ÆThe height extensions are
bolted to the support frame or
height extension below using
the eight (8) M20x50 screws and
M20 nuts supplied.
ÆThe pre-assembled units
should rest on square timbers
(face down) on the ground be-
fore they are flown into place.
Assembly of the Triplex SB
braces
Depending on the overall height,
it may be necessary to attach
TriplexSB braces to the height
extensions150 and the base
extensions. The fastening ele-
ments required are supplied with
the height and base extensions
(Figures 12.2 to 12.4).

Attention
ÆWhen using the STB unit
vertically, the spindle must be
set to the middle position before
mounting the STB on the form-
work. This ensures that it can
be perfectly adapted to suit the
supporting surface.
ÆBefore pouring, ensure that
all STB spindles and additional
braces are secure and contact
the ground.

Working platforms are built using
walkway brackets 90 (Fig.16.1)
together with guardrailing posts.
The procedure is as for two-sided
wall formwork. For details see
the Technical Instruction Manual
of the formwork you are using.
For safe access to the platform
we recommend using the MEVA
Stair Tower.
Permissible load:
1.5 kN/m², load class2 according
to DIN12811-1. Maximum influ-
ence width: walkway bracket90
= 1.80m
Planking classification S10.
Platform layout
The STB units can be set up flex-
ibly and combined with different
formwork systems and heights.
When planning, take the plat-
form layout and the fall height
into account.
STB 450
The planks and boards can be
attached to the support frame
or the height extension (Fig-
ures16.3 and 16.4). The guard-
railing posts are inserted directly
into the support for guardrailing
post of the STB 450 or the height
extension.

An access ladder with safety
cage is required if the support
frame 450 is used. The distance
from the ground to the safety
cage must not exceed 3m. The
ladders are attached to the wall
formwork panels using the lad-
der fixture 33/45, regardless of
whether a crossbeam or align-
ment rails are used (Figures17.1
to 17.4). The ladder fixture is
bolted to the multi-function pro-
files of the wall formwork panels
using flange screws 18.
Three ladder fixtures 33/45 are
required for formwork heights
between 350cm and 450cm.
For heights above 450cm please
contact MEVA.
Note
ÆAlternatively, a MEVA Stair
Tower can be employed to
access the working level.
ÆA MEVA Stair Tower is re-
quired above a height of 5.00m
if there are no intermediate
working levels.

Anchoring details – General
Fig. 18.1 Support frame STB 450
Anchoring
Anchors for support
frame450 (Fig.18.1), support
frame300plus (Fig.18.2) and
support frame300 can be made
for different floor slab thick-
nesses using anchor loops or
DW tie rods, coupling nuts and
anchoring auxiliaries.
All parts are designed for the use
of DW15, DW20 and DW26.5
tie rods.
The anchoring auxiliaries can
be attached either to the upper
(Fig.18.3) or to the lower rebar
layer (Fig.18.4) depending on
the slab thickness or the number
and density of rebars. The angle
of installation of the tie rods is
automatically correct due to the
shape of the anchoring auxilia-
ries (45°).
Depending on the version it may
be possible to recover and reuse
the tie rods (see page STB-21).

Anchoring details – General
Decisive for the choice of tie
rod are the forces that occur at
the anchor point of the support
frame. Anchoring can be per-
formed as follows:
ÆWith tie rod DW15
(Fig.19.1) and M cross stiffener
44.
ÆWith tie rod DW20 or
DW26.5 and twin channel 80/22
or 245/22 (Fig. 19.5).
ÆWith anchor loop15
(Fig.19.2) or 20 and twin
channel (Figures19.3 and 19.4)
or with anchor loop 15 or 20
turned through 180° (Fig.19.4).
Contact the structural engineer if
additional rebars are required.
Maximum anchoring loads:
Tie rod DW
DW 15 = 90 kN per tie rod
DW 20 = 160 kN per tie rod
DW 26.5 = 250 kN per tie rod
Anchor loop
DW 15 = 180 kN
DW 20 = 320 kN

ÆAnchor 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.
ÆSingle/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°.
ÆThe 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.
ÆCoupling 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
ÆFixed anchors DW15,
DW20 and DW26,5 (Fig.20.6),
to anchor the tie rods inserted
through the anchor holderDW.
