Safe anchoring from fi scher


To anchor post installed rebar safely in concrete, fi scher offers two special systems. fi scher highlights that these rebar systems open up entirely new opportunities for structural engineers and also make professional post installed rebar applications signifi cantly easier for site engineers and installers.


made totally of reinforced concrete. Often, existing buildings are extended or rebuilt. This means in practice that the reinforcement of old and new sections of buildings have to be connected.

Choice of two systems fi scher now offers two special systems which make the


installation of post installed rebar a straightforward process. The rebar is inserted, into the maximal two metres deep, drilled and cleaned holes in the concrete member. Post installed rebar are handled and loaded like cast-in rebar after the full curing time. Both systems have European Technical Approval (ETA) and a General Construction Approval by the ‘Deutsches Institut für Bautechnik (DIBt)’.


einforced concrete is used in virtually all building constructions: foundations, (fl oor) slabs, beams and columns. Civil engineering construction such as bridges, tunnels or power plants are often


The two systems are: • The established fi scher Injection Mortar System FIS V (ETA-10/0383) based on a high-performance vinylester hybrid mortar for easy handling and rapid curing times.


• The fi scher Injection mortar System FIS EM (ETA-10/0012) based on best performance epoxy resin mortar for rebars up to a diameter of 40mm. Also suitable for diamond drill holes with easier drill hole cleaning.


Special anchor FRA The fi scher rebar anchor FRA has been designed especially


for extreme tension loads, e.g. at a column base, which can’t be transmitted to the concrete member by conventional anchors. The FRA is composed of a rebar connected to a stainless steel threaded rod by friction welding. Therefore it is also approved for outdoor use. The approval regulates connecting threads from M12 to M20 and allows tension loads up to 97.6kN.


Tecfi ensures high quality products


Tecfi S.p.A, an Italian company specialised in design, production and distribution of fi xing systems, explains that some of its fi xing systems are covered by ETAG Guidelines, through which it is possible to get European Technical Approvals preparatory to the CE mark of the products.


In particular, Tecfi products are covered by the ETAG Guidelines:


• Metal anchors - Guideline ETAG001. • Plastic anchors - Guideline ETAG020. • Three dimensional nailing plates - Guideline ETAG015.


The ETAG001 Guideline, which regulates metal anchors,


provides a number of very diffi cult and selected tests at qualifi ed laboratories and many tests are run in extremely hard conditions, especially if you choose option 1, which guarantees the installation of the anchor even in cracked concrete. The ETAG020 Guideline, which regulates nylon anchors,


provides a number of very challenging tests too. Many tests are run in extremely hard temperature conditions and during span of time which can be quite long (about 3 months, without any interruption). The ETAG015 Guideline provides a big number of tests,

structures, in compliance with Eurocode 5. Tecfi S.p.A says that it has taken the hard way of gaining


technical approvals in order to ensure its products reach CE certifi cation, and due to this has received some very impressive results. Below are the range of Tecfi products that have already


received ETA accreditation: • Tecfi high performance anchor HVE Rock®


ETA 10/0060 - Option 1.


• Tecfi steel anchor with conical nut and sleeve DXE - ETA 10/0453 - Option 7.


• Tecfi steel anchor DSE anchor - ETA 08/0058 - Option 7.


• Tecfi DGE02 bonded anchor - ETA 10/0102 (with rod) and ETA 10/0103 (with rebar).
