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.

See page 19 for details. Acrowall ST Tightener Used with the Acrowall Punched Steel Tape. 10 Acrowall Panel Plug (Orange) Plugs open tie holes. General Technical and Application Manual Element Connection Acrowall panels are connected using the Aligning Clamp. The aligning clamp provides a tension resistant, tight joint between panels as well as holding the panel in rigid alignment. 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.

Adjustment Waler Waler Connection 300 Tie >30 0 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. Timber makeup Adjustable Aligning Clamp Plug 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. HT Thru Tie Rod Wing Nut Acrowall panel rib Plate Washer Stirrup bolt Acrowall Edge Tie Bracket Threaded bolt Finger Holes at 50mm intervals in steel tape 19 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. Punched 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. Acrowall-60 Formwork System 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.

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. Acrowall-60 Formwork System 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.
