The installation-friendly internally threaded anchor for fixings in pre-stressed hollow-core concrete slabs.

Hollow-ceiling anchor FHY

The fischer hollow-ceiling anchor FHY is an internal threaded anchor made from zinc-plated and stainless steel. The FHY is ideal for the anchoring of pipelines, cable trays, and ventilation systems in pre-stressed concrete hollow slabs both inside and outside. The general building approval ensure added safety. The hollow-ceiling anchor is set in the drill hole by hand in a pre-positioned installation and is driven in flush to the surface of the building material using a hammer. The easy installation saves time. The embossed edge prevents the anchor sleeve from slipping deeper into the cavity, which makes the installation process easier. When the torque is applied, the cone is pulled into the expansion sleeve. This expands in the cavity and braces itself against the wall of the drill hole in the solid building material.

Advantages

The active principle of the anchor means that the FHY can be used in cavities or in solid materials up to 5 cm from the tensioning wire. This ensures the highest flexibility and user-friendly installation.
The embossed edge prevents the anchor sleeve from slipping in the cavity, thus allowing for trouble-free installation.
The optimised geometry minimises setting energy and allows for use in extremely narrow spaces. This allows for user-friendly installation.
The metric internal thread means that it is possible to use standard screws or threaded rods for the ideal adaptation to suit the intended use.

Building materials

Approved for:

Pre-stressed hollow-core concrete slabs ≥ C45/55

You can find detailed information on building materials in the registration document.

Functionality

The FHY is suitable for pre-positioned installation.
Position the FHY hollow-ceiling anchor in the drill hole and drive in flush to the surface of the anchor base using the hammer.
The FHY pre-positioned anchor must be able to be supported on the attachment for expansion.
When applying the torque, the cone is pulled into the expansion sleeve and expands it into the cavity or expands it in the solid material against the drill hole wall.
