Acrowall-60 Formwork System
Important
The erection and application instructions contained in this booklet are the
recommended methods to be used for Acrowall products.
The technical function related instructions must be accurately followed to obtain
the correct workability of the product. Any deviation from the recommended usage
will require a separate design and/or verification by
Acrow Formwork & Scaffolding (AF&S) Engineering Department.
The safe use and application of the Acrowall system must be in accordance with
Australian Standard AS 3610 Formwork for Concrete, Occupational Health and Safety
Regulations, approved industry codes of practice and relevant regulatory authority
requirements.
The illustrations in these assembly configurations are minimum guidelines only.
The combined use of the Acrowall system with equipment from other suppliers may
entail performance problems and therefore requires a design check and/or verification
by AF&S Engineering Department.
Safe Work Methods Statements and Hazard Identification/Risk Assessments for the
erection and dismantling of the Acrowall system are available from AF&S Branches.
Site specific Hazard and Risk assessments may need to be generated for specific
projects.
Safety Warning
This warning is to draw the users attention to possible musculoskeletal
disorder as a result of manual handling during assembly and dismantling
of Acrowall panels.
It is recommended that users of the Acrowall panel system employ and implement
appropriate procedures and control measures to eliminate or control any risk of
Musculoskeletal disorder/injury while manually handling Acrowall panels
Refer to Code of Practice on manual handling published by local Workcover Authority
or other approved and recognised guidelines for correct and appropriate manual
handling procedures.
Product Features
Acrowall is a galvanised steel frame panel with a 14mm plywood face.
The panel weight of a 2700 x 750 panel is only 60kg. Panels up to 2700 x 750 may
be manually handled or built into a large crane handled assembly for fast movement
of formwork.
The maximum permissible concrete pressure is 60kPa for single panel height form
arrangements up to 2.7m or 55kPa for height extended form arrangements.
The built-in strength in the design of the Acrowall system makes the assembly simple
with a minimum of components. The aligning clamp locks the panels rigidly together
and accurately in line. Panel assemblies stay free of twist even when being crane handled.

Acrowall Aligning Clamp
on vertical panel joint
2700
When joining a 1500 high panel to a 2700 high panel
horizontally adjacent to each other, as shown on the left,
the ribs on the two panels are not exactly in line, however
the first and third ribs on the 1500 panel are close enough
to allow an aligning clamp to be used.
1500
Acrowall
Aligning
Clamp on a
horizontal
panel joint
It can be used on both vertical panel joints and on
horizontal panel joints on height extended panel
arrangements.
Note:
In multiple height assemblies additional clamps may be
required to stiffen joints between panels prior to crane
handling of the formwork assembly.
2700
All Acrowall clamps can be tightened, not by striking the
locking screw, but by inserting a podger bar into the hole
in the screw head and tightening the screw in a spanner
action. This method is labour saving, prevents damage to
the screw and is quiet.
In height extended walls, using the adjustable aligning
clamp which is longer than the aligning clamp enables the
panels to be joined together along the rib of the horizontal
panel with the clamp picking up across two ribs of the
vertical panel thus providing true vertical alignment.
Because of its greater length, the Acrowall Adjustable
Aligning Clamp achieves perfect alignment in this
application as it braces against the panel ribs.

The internal corner panel has built-in stiffener plates which when locked hold
the panels rigidly to a right angle. When the stiffener plates are unlocked the
panel angle can decrease by 2° allowing the form to move away from the

adequately support the corner joints even if timber
makeup is used.
The external corner is made up using a
combination of panels so that the panel joints
line up with the internal corner panel. In this
way the tying system can be used adjacent
to the corner panel for full strength.

To cater for non right angled corners hinged corner panels
are available in two widths 150 x 150 and 300 x 300.
The 300 wide hinged panel can only be used on the
internal face.
Due to the varying growth in wall length for obtuse corners
it is not always possible for panel joints to line up. MP
panels are ideal for such applications as it gives greater
flexibility in placement of ties.

Acute Corners
Hinged Corner Panel 300 x 300
The Hinged waler solves the problem of tying when Acrowall
is used to form acute-angled corners (< 90°).
The Hinged Waler is attached to the end panel by the Waler
Connector 500mm in conjunction with a Tie Rod Bracket.

Because the 300 x 300

the same side bar as a
standard panel it can be
joined to adjacent panels
with the Centring
Tension Bolt and Nut or
by using the Aligning
Clamp.
The 150 x 150 corner
panels, however have a
flat side bar so the
alignment clamp cannot
be used to joint them
to a standard panel.

Note:
When using the 300 x 300 hinged corner panel on an
acute angled internal form face, if the angle is less than
70° then the tie rods will clash. In this situation MP panels
would have to be used on one side of the hinged corner
panel to enable the ties to be offset from the joint to
allow clearance.

T-Junctions
Stopends
Wall T-junctions can be easily accommodated using
standard panels together with timber and plywood
makeups where necessary.
The holes in the edge profile of the panels provides a
means to fasten support for stopends. Centring Tension
Bolts and Nuts can be used through the holes to secure
Adjustment Walers.

General Technical and Application Manual
Tying
Acrowall assemblies are tied using the thru tie system
through the tie hole positions in the panels. Before insertion
of the tie rod the plastic plug must be removed, all holes
not used by ties must be plugged to prevent grout loss.
If timber makeups are used for adjustment at a panel joint,
tying is more effective if made through the timber makeup.
Plastic spacer tube and plastic cones must be used with
the thru tie system.

Note: Cones and Spacer Tube are not in assembled position for clarity.
In foundation walls it is often difficult to tie the formwork.
When using single panels horizontally a simple method is
to use the Acrowall ST Tightener and Punched Steel Tape
at the base and Acrowall Edge Tie Brackets at the top of
the form.

Acrowall ST Tighteners are inserted into the ribs of the
horizontal panels. The finger of the Acrowall ST Tightener
is inserted into one of the holes in the steel tape and the
formwork is adjusted using the threaded bolt which takes
up the slack in the tape so the tape can resist the tensile
force resulting from the concrete pressure.

Steel Tape
Note:
Maximum permissible load for either the Steel Tape system
or the Edge Tie Bracket is 10kN.
For 900 high foundation walls this means a maximum
horizontal distance between ties of 1.5m.

Column Formwork with MP Panels
Columns using Standard Panels
The MP Panel (multi-purpose panel) with its continuous
rows of tie holes is ideally suited for the construction of
smaller/odd size columns.
Column forms made of standard Acrowall panels can
be simply and quickly assembled for a wide range of
dimensions using the outer corner clamp.
Four MP panels assembled in the configuration depicted
below can create a variable form for square or rectangular
columns with adjustment in 50mm increments from
150mm to 550mm.
By arranging the panels in pairs or offsetting them, or by
using a timber packer at the panel overlap, the form can be
built for column cross sections ranging in size from 200mm
to 850mm maximum.

Brackets
The Acrowall Platform Bracket hooks into the holes of the
panel ribs to provide a 730 mm wide working platform
suitable for 3 timber planks in width.
The bracket features a tubular socket at its end into which
a guardrail post is attached using a Ø16 connecting pin or
Frame Locating Pin. The timber planks are bolted to the
top plate of the bracket to provide the platform.

Stepped Forms
The Acrowall Offset Clamp can be used to join panels
in stepped formwork applications. It attaches to the ribs
of adjoining panels both joining and aligning them.
Although it can be used as a substitute for a normal
Aligning Clamp since its aligning member bears directly on
the horizontal ribs it is intended to be used for applications
where the height difference of the adjoining panel is
between 60-270mm.
The vertical alignment member
must bear against two horizontal
ribs of the adjoining panel.

Struts
The adjustment range of the
Acrowall plumbing brace allows
it to be used on either the 2700
panel or the 1500 panel.
When two panel high
arrangements are used, the
top panel is plumbed by using
a combination of an Acrowall
Prop Connector Assembly used
in conjunction with a double
nutted Acrow prop, an Acrowall
Prop Connector End and an
Acrowall Raker Foot Bracket.

Crane Handling
The Transport Hook must always be connected to a
panel joint. With the Fastening Bolt withdrawn, the hook
is guided over the panel edge profiles and aligned with
the top hole. When the Fastening Bolt is fully inserted, the
Transport Hook is ready for use.
On an Extra Large Panel 2700x2400, the connection point
for the Transport Hook for individual panel handling is in
the corner at the rail profiles. Units for crane handling must
not comprise more than 3 Extra Large panels.
