Introduction to Hollow Core Slabs:Hollow core slabs are a very common material made of precast concrete, steel and composite structures for use in retail, industrial, commercial building and car parks as well as in housing, educational and government projects.

Technical Information:

Hollow Core Floors are manufactured using a long line casting technique with automatic casting equipment which places high strength, low water/cement ratio concrete under a high degree of vibration and compaction.

The section profile incorporates hollow cores to reduce self-weight without significant reduction in section stiffness. Reinforcement is by high tensile prestressing strand or wire which has an ultimate strength of more then 3 times that of conventional high tensile reinforcement. The structural performance resulting from the combination of those featured produces a slab which is highly efficient and economic for any load/span situation.

Testing of Fischer Fixings in Bison Hollow Core Slabs

We confirm that the tests as detailed in your document title “Fixings Testing on Bison Hollow

Core Slabs”, were carried out in our laboratory. The tests were carried out on the soffit of a

standard 150 mm deep slab, and the results are a true record of the tests. Therefore, we can

recommend that the fixings described are suitable for use with hollow core slabs, up to the

safe working loads stated.

The fischer Hollow Ceiling Slab anchor FHY has been developed specially for fastenings in hollow core slabs of prestressed concrete. It is designed for use with standard bolts or threaded rods with metric threads from M6 to M10. The FHY is installed flush with the concrete surface. When the bolt or the nut is tightened a tapered element is pulled into the sleeve, which presses this outwards. In this way, the FHY presses against the sides of the hole, creating a friction fit. If the anchor encounters a cavity during installation, the expansion of the sleeve forms a Y shape. The holding power is now the result of a combination of expansion pressure and formfit. The FHY offers considerable scope in the location of attachment points. Unlike other competing products, it does not have to be located at the centre of the cavity axis, which is often very difficult to define. Instead, it can be located down to a minimum distance of 50 mm from the pre-stressing steel.

FDA-R Drop in anchor

The FDA-R is a drop in anchor with a rim so that the anchor remains flush with the surface of the substrate at all times. As the anchor retains its position item that has been attached to the substrate can be removed and refitted several times with no effect. The drill hole can be a slightly deeper depth without effecting the anchor’s performance. This anchor is suitable for use with all types of screws and studs with a metric thread.

Concrete ≥ B15 and dense natural stone plus hollow core slabs.

The frame fixing screw, type FFS provides stress free standoff installations without the use of additional plugs. The continuous thread ensures that the fixture cannot be pulled up against the building material. Distortion of the profile will therefore not take place, either during or after installation (for instance when applying insulating foam). The distance is also maintained when loads are subsequently applied. The long screw length make exact positioning easy.

Concrete ≥ B15 and masonry building materials.

fischer concrete screws have a specially hardened thread. The lower turns of the thread also have a serrated edge. The diameter of the hole and the thread of the screw are adapted so that the serrated thread of the screw cuts into the concrete. The thread turns creating a fine undercut, ensuring that the load is safely supported by a perfect form fit. The teeth allow the thread to cut into the concrete, thereby reducing the amount of energy required to insert the screw into its position.

The fischer gravity toggles are standard cavity fixings for ceiling, wall and floor fastenings. With their long threaded rod, they will also bridge large wall thicknesses. The fixings are protected against corrosion as they are zinc plated and yellow passivated. The KD8 possess a toggle bar which automatically “locks” in cavity spaces.

Technical Data

The table below shows the ultimate and maximum safe working loads of all the anchors tested into the section product of BISON hollow core slabs or Tarmac Topfloor 150 spirall units. The tested slabs have a concrete web thickness of 25 mm and a minimum compressive strength of 55N/mm2. These results are tabulated below starting with the highest performing anchor at the top.

Technical data

ConclusionIt is in our opinion that the fixing types tested in conjunction with hollow core slabs e.g. Bison are highly suitable for typical applications e.g. various M + E services, timber battens, insulation, suspended ceilings etc. As the tests were conducted into the thinnest of the manufactured slabs (150 mm overall depth), it is our opinion that the fixings would be suitable for all slab sections varying from 150 - 450 mm deep with web thicknesses greater than 25 mm. The test results for all of the fixing tested offers good variation in ultimate loads. This allows the Engineer/Architect/End user to have a broad range of anchors to choose from depending on both function or load performance.Axial spacings vary from anchor to anchor due to the expansion or form-locking characteristics. In our opinion it would be suitable to have axial spacing >200 mm for all the anchors tested except the FIS V 360 S and FFS screw. The axial spacing for the FIS V 360 S as written above are conservative, for more detailed, comprehensive and possibly smaller spacing further testing should be carried out. Note: The FIS V 360 S resin with FIS H N net achieved a very large concrete cone failure during testing. This cone is larger than the characteristic cone failure expected in standard reinforced concrete due to the compressive stress patterns that the pre-stressing induces. For further information on the testing, please contact our Technical Team.
