123 FOR USE WITH FIS EM mortar FIS V mor tar FIS VS mortar see page 67 see page 71 see page 79 Rebar connections Rebar connections Professional rebar connections ADVANTAGES ▪ The injection mortars FIS V / VS allow for rebar connections from Ø8 to 28 mm, whilst injection mortar FIS EM allows for rebar connections up to Ø40 mm to be carried out. This offers maximum flexibility . ▪ FIS EM also allows for the execution of rebar connections in diamond-drilled holes. ▪ The FRA with connecting thread in stainless steel A4 fully utilises the load-bearing capacity of the concrete. This means that extremely high tensile loads can be introduced into the base material. ▪ Accessories in line with building site requirements, such as injection adapt- ers and extension tubes, ensure rapid progress. ▪ The FIS rebar case contains all of the individual components required, thus ensuring a convenient installation. APPLICATIONS ▪ Post-installed concret e steel bars, e.g. for overlap connections, end anchor- ings, starter bars, needlings etc. ▪ Rebar anchor FRA FUNCTIONING ▪ Anchoring as with cast-in reinforce- ment bars in line with Eurocode 2 and DIN 1045-1. ▪ The mortar is extruded bubble free into the drill hole using the injec- tion adapter. The geometry causes a build-up of pressure in the drill hole, which pushes the injection adapter and extension tube automatically out of the drill hole. ▪ The mortar bonds the entire surface of the reinforcement bar with the drill hole wall. ▪ A special certification is necessary for installation according to approval in Germany. The fischer Academy offers the relevant training courses.

Injection system FIS V, FIS VS and FIS EM with Rebars from steel type BSt 500 S5)
Design resistant loads and permissible tensile loads1) 6) of a single post-installed Rebar in concrete C20/252).
For the design and planning the complete approval ETA - 09/0089 and ETA - 08/0266 have to be considered.
1) The partial safety factors for material resistance as regulated in the European Standard EN 1992-
1-1 as well as a partial safety factor for load actions of L = 1,4 are considered.2) The ETA-approvals for FIS V and FIS EM allow post-inst alled rebar connections in concrete C12/15
up to C50/60. When using another concrete strength class the given basic anchorage length will
change.3) When using the full steel capacity.4) Basic anchorage length" according EN 1992-1-1, chapter 8.4.3 for concrete strength class
C20/25 for "good bond conditions"5) Rebars with a characteristic yield strength fyk = 400 - 600 N/mm² according EN 1992-1-1
Annex C,Table C.1 and C.2N are permitted. When using an other steel quality the given basic
anchorage length as well as the steel capacity (see foot note 3) will change.6) Fixations with post-installed rebars with FIS V and FIS EM are permitted in dry and wet concrete
for temperatures in the substrate up to +50°C (resp. short term up to 80°C) and best possible
drillhole cleaning according approval.7) For determination of the installation measures (minimum concrete cover, spacings e.g.) as well
as an eventually required transverse reinforcement see EN 1992-1-1 and the general instruction
rules of the approvals.
