PRESS RELEASE March 2008 Fischer hammerset EA II Load capacity up to concrete load limit The fischer group of companies of Waldachtal has upgraded its hammerset anchor. The new EA II has significantly improved properties and excels with ultimate load bearing capacity. Concrete anchor bases can now be utilised up to their load limits. And a formed rim prevents the anchor from slipping deeper during installation. The superiority of the EA II shows in the direct comparison. It can take as much as 69% higher tensile loads in non-cracked concrete than other products on the market. Compared with its predecessor, the tensile loads are as much as 100% higher in non-cracked concrete, and the shear capacity is as much as 157% higher. Up to 350% higher tensile loads apply in multiple fixings of non-load-bearing systems in non-cracked concrete. With an embedment depth of 40 mm the EA II M10, for instance, reaches a load-bearing capacity in tension load tests of 6.1 kN and is therefore a great deal more efficient than similar competitors’ products. The EA II is designed for use in construction and civil engineering, but also for locksmith work and in steel construction for single fixings (ladders, shuttering props, steel constructions) in non-cracked concrete if the failure of a fixing point would result in danger to life and health or in substantial property damage. It is also suitable for use in structural engineering for multiple fixings of redundant non-load-bearing systems (suspended ceilings, pipes, cable routes) both in cracked and noncracked concrete. The European Technical Approval (ETA) is valid for noncracked concrete B25 to B55 or C20/25 to C50/60 and for the (redundant) multiple fixing of non-load-bearing systems in cracked concrete C12/15 to C50/60. In terms of passive fire protection, the EA II also offers a fire resistance of as much as 120 minutes (R120 under TR020). The EA II is available both in zinc-plated steel and in stainless steel grade A4 (1.4401 / 1.4571). The range includes the sizes M6 to M20 and shows a number of special features: the thicker-walled EA II M12 D is suitable for fixing diamond saws and core drills. The EA II 10x30 is chosen if a thread diameter size M10 is required (e. g. Factory Mutual (FM) Approval) and if a lower load-bearing capacity or a lower drilling depth is sufficient to avoid potential reinforcement hits. The EA II M8x40 is suitable if size M8 is sufficient (lower priced than M10) but a somewhat higher load-bearing capacity is needed in non-cracked concrete (only for single fixings according to ETA, Option 7). All material variants have a formed rim which prevents the anchor from slipping deeper into the drill hole if the hole has been set to deep and which fills the drill hole crater better; there is no need to set the drill hole depth to exact values. The EA II is suitable for all types of screws or threaded bolts with metric thread. The EA II is driven in with the manual setting tool EAW H Plus or with the machine setting tools EA II S-SDS. The anchor sleeve opens up and is wedged against the drill hole wall. If set correctly, the setting tools stamp the EA II with a marking, allowing an easy visual setting check. With its optimised expansion cone, the EA II is easier to set and process than many of the competitors’ products. A few hammer blows are sufficient. Thanks to the anchor which is now set flush with the surface, fixtures can be detached and fixed repeatedly. The ductile steel provides higher safety against overloads acting on the anchor sleeve, for instance if a threaded bar is over-tightened. The new fischer EA II hammerset anchor uses the full load-bearing capacity of the concrete. Graphics/photo: © fischerwerke, Waldachtal
