HA LF E N S A N DWICH PANE L A NCHOR S Supporting Systems Function of the anchors Sandwich panels with the MVA supporting system have one sleeve anchor as a supporting anchor at the centre of gravity of the facing layer and one torsion anchor. For panels with a MVA-FA supporting system there are 2 supporting anchors (MVA and FA), the sleeve anchor serving simultaneously as a horizontal anchor. Panels with SPA-SPA and FA-FA supporting systems basically have 2 supporting anchors, i.e. anchor groups, and 1 horizontal anchor (in the case of panels rotated for transporting, 2 horizontal anchors...

HA LF E N S A N DWICH PANE L A NCHOR S Anchor Calculation Basics The calculation values for the load capacities VR,d, NR,d, MR,d are resistance values taking the partial safety factors for the materials into account. The resistance for VR,d, NR,d, MR,d need to be compared with the partial safety coefficient increased effect VE,d (vertical loads, for example dead load of the facing layer and if required any additional loads present), NE,d (horizontal loads, for example from wind loads and deformation) and ME,d (only for the MVA/FA and FA/FA systems) and the specifications in the appropriate...

HA LF E N S A N DWICH PANE L A NCHOR S Anchor Types Sandwich panel anchors SPA Colour marking Colour Article name: Anchor type Sandwich panel anchors SP-SPA-1 and SP-SPA-2 are V-shaped anchors of round steel bar diameter 5.0 mm, 6.5 mm, 8.5 mm and 10.0 mm. The bent ends serve both as anchorage in the concrete and to secure the reinforcement bars. Sandwich panel anchors are used in SPA-SPA systems as supporting anchors. They are identified by coloured adhesive labels showing type, diameter and height. Material: stainless steel A4 Ordering example: Article group Anchor type Round steel bar ø...

HA LF E N S A N DWICH PANE L A NCHOR S Anchor Types Torsion anchors / Horizontal anchors The following anchor types can be used in sandwich panels as torsion or as horizontal anchors. Sandwich panel anchors SPA The sandwich panel anchor SP-SPA-1 is used in SPA-SPA systems as a horizontal anchor (where necessary the SP-SPA-2 can also be installed as a horizontal anchor). Material: stainless steel A4 Flat anchor FA The flat anchor is used in the MVA system as a torsion anchor and in a FA-FA system as a horizontal anchor.
