Anchor Installation

Void Installation

· Flex open void former to allow anchor installation · Install anchor into void former

· Anchor and void assembled

Anchor Installation

Positioning Anchor-Void assembly

· The anchor and void assembly is placed into position. · If a tension bar is installed, care should be taken to place the mesh and perimeter bar to allow the tension bar to sit flat on the mesh

· Central Mesh and perimeter bar are located between the JAWSTM legs.

Anchor Installation

Setting Bolts

· Secure anchor and void assembly to the sideform with 2 setting bolts.

If magnetised voids are not used then double sided tape or Support Plates should be used to secure the void against the formwork

Anchor Installation

Shear Bar and Tension Bar installation

· For JAWS ULTRA and Two Hole Anchor, install Tension Bar and use tie wire to secure into position.

· Install Shear Bar and use tie wire to secure anchor, void, mesh and shear bar into position.

Final Set-up position

· Set-up for JAWS Lite ­ SJL JAWS Standard ­ SJM JAWS Heavy ­ SJH JAWS Xtra - SJX

· Set-up for JAWS Tension ­ SJT JAWS Ultra ­ SJU

JAWS Installation

With the void hard up on the formwork, the ties are recommended to secure the anchor and shear bar so that the poured concrete does not move them out of position

The void can be held against the formwork by:

1

· Setting bolts,

3 · Double sided tape · Support plates · Magnetised voids, or

2

· Reinforcing mesh

The anchor assembly should not restrain the panel steel, as this could lead to clutch engaugement issues and spalling. Tie in the tension bar to the rear of the anchor hole

Stripping

Removing EdgeLifter void formers and stripping

· Strip sideform, formwork and false work from the panel

· The EdgeLifter void former is levered out of concrete as shown in the diagram above.

Rigging

Engaging SwiftLiftTM JAWSTM Clutches

· Lower clutch slot over anchor

· Rotate the locking ring arm until it rests on the concrete surface

· Before lifting, ensure clutch is FULLY engaged with the locking ring in full lock position.

Sling Angle

The shorter the slings the higher the load on the anchors. For example, at an included angle of 170 degrees the load on each sling is six times the weight of the actual load being lifted.

It is recommended not to

NOTE: Never make the sling length shorter than the distance between two
