Fastener Fair 2011: fischer injection technology

Safety in every base

Waldachtal, February 22, 2011 --- The fischer group of companies of Waldachtal/Gemany shows its full range of injection technology at the Fastener Fair (22 to 24 February 2011 in Stuttgart/Germany). The different injection systems meet every national and international safety standard in fixing technology and guarantee safe bonds in every base material.

Approved high-efficiency resins for all building materials

The fischer high-efficiency resins FIS V 360 S and FIS VW offer a wide range of uses with official construction approval. The German approval (DIBt) covers masonry and aerated concrete, reinforcement links, facing brick refurbishment anchors, weathering shell refurbishment anchors and the Thermax spaced installation system. The European Technical Approval (ETA) also covers concrete. These high-efficiency resins also have the fire test certificate for concrete, masonry and aerated concrete.

Injection resin for the winter season

The only injection resin with German approval for masonry (solid and perforated bricks), aerated concrete and with the European Technical Approval (ETA) for concrete, the fischer FIS VW 360 S is the specialist in installation work at temperatures of +10°C to–15°C. It cures twice as fast as all similar approved products. Thanks to its optimum processing convenience, it is the ideal choice for work in the cold season, with users able to set substantially more anchors in a shorter time.

Post-installed reinforcement bars

For post-installing reinforcement bars and reinforcement threaded bars safely in concrete, fischer offers two special systems which allow structural engineers to work with entirely new options and loads. Professional reinforcement link work on site is also made a great deal easier for certified businesses and craftsmen. The method involves setting and cleaning out drill holes up to 2 metres in depth, filling the drill holes with fischer injection resin and finally pushing the reinforcement bar into the hole. After the specified curing time, the reinforcement bars can be treated and loaded just like normal concrete-set bars. Both systems are ETA and BIBt approved, with the tried and tested fischer injection system FIS V based on a vinyl ester hybrid resin for easy installation and short curing times, and the new fischer injection system FIS EM based on epoxy resin for reinforcement bars with as much as Ø 40 mm, also for diamond drilling work and significantly easier drill hole cleaning.

FRA is half plug, half reinforcement

The fischer FRA reinforcement thread anchor has been developed specially for anchoring extreme tensile loads such as column bases which can no longer be transferred to the component with conventional anchors. The FRA consists of a reinforcement bar connected via friction welding to a reinforcement bar made of stainless steel. The FRA is therefore also approved for outdoor use. The approval covers connecting threads below M 20 and allows tensile loads of as much as 97.6 kN.

FHB II PF curing in record time

The fischer Highbond Anchor FHB II is the world’s first resin bond anchor approved for the tensile zone using cartridges and injection systems. Both the shorter standard type FHB II-AS and the performance optimised longer FHB II -AL can also be used with the injection resin FIS HB or with the standard resin cartridge FHB II P. The resin cartridge FHB II-PF cures as much as 90% faster than the best competitor system. Just two minutes are sufficient for 100% curing of the resin at a temperature of 21°C. While the standard injection resin FIS HB 345 S cures in winter (0°C) in about three hours, the previously offered fischer cartridge FHB II P cuts the curing time to 45 minutes – now only 6 minutes with the FHB II PF.
