Panel building materials are thin-walled materials that often have only low
strength - e.g. plasterboard like “Rigips”, “Knauf”, “LaGyp”, “Norgips”; Gypsum
fibreboard like “Fermacell”, “Rigicell” or chip board, hard fibre boards, plywood,
among other things. Special fixing must be selected for optimum reinforcement;
so-called cavity fixing. These are fixings of plastic or metal and expand on the
reverse side - fixings engaging with form locking that can anchor directly on the
reverse side of the panel in the cavity.
Prestressed concrete hollow ceilings are concrete slabs that contain
standardised cavities and are reinforced with tensioning wires (steel wires) on
the rear side. The size of the cavities and the distance from one another as well
as the mirror thickness (thickness of the concrete of the ceiling bottom up to the
beginning of the cavity) are exactly prescribed. There are only a few anchors with
building authority approval for this base (e.g. FHY).
▸ Expert tip
▪ Use only those anchors in simple materials, boards or prestressed concrete
hollow slabs that are permissible or suitable for these substrates.
▪ Contact your fischer consultant on site before anchoring heavy or safety-relevant
loads in aforementioned substrates.
