Corrosion protection

— The stainless steel used with the Schöck Isokorb® type RKS complies with the Material No.: 1.4362, 1.4401, 1.4404 or 1.4571. Ac-cording to the general building supervisory approval document Z-30.3-6 Annex 1 „Structural components and connecting elements made from stainless steels“ are rated in Resistance Class as III/medium.

— The connection of the Schöck Isokorb® type RKS in conjunction with a galvanised or corrosion protection coated face plate, with regard to contact corrosion resistance, is uncritical (see approval Z-30.3-6, Section 2.1.6.4). With connections using Schöck Isokorb® type the surface of the base metal (face plate made from steel) is signi� cantly greater than that of the stainless steel (bolts, shims and dogs), so that a failure of these connections as a result of contact corrosion is excluded.

Schöck Isokorb® type RKSNotes

The information on the load-bearing structure planning on pages 26 - 29 is to be observed.

Lifting loadsUpwards directed shear forces (e.g. from wind suction) CANNOT be taken up ordinarily by Schöck Isokorb® type RKS.

Verification in the serviceability limit stateFor the veri� cation in the serviceability limit state the spring values of the Schöck Isokorb® are to be taken into account.So far as an investigation of the vibration behaviour of the steel structure to be connected is necessary, the additional deformation resulting from the Schöck Isokorb® is to be taken into account

CamberThe deformation factors given in the table result alone from the elastic steel elongation of the Schöck Isokorb®. The � nal camber of the balcony results from the deformation calculation of the connected balcony structure together with the deformation from the Schöck Isokorb®.

Deformation (wü) as a result of Schöck Isokorb®:wü [mm] = tan α · lk · 10 MEd / MRd

tan α Deformation factor (see table)lk Projection length [m]MEd Relevant bending moment for the calculation of the camber.

The load combination to be applied for this can be made by the structural engineer.MRd Design value bending moment for the Schöck Isokorb®

Note: The given values serve solely as approximation for the estimate for the deformation from Schöck Isokorb®. Further deformation amounts, which have to be considered, can added be to this.

Expansion joint spacingThe determination of the allowable joint spacing is to be based on a balcony slab made from reinforced concrete securely connect-ed using the steel beams. If structural measures have been carried out for the movability of the balcony slab and the individual steel beams, then only the spacing of the immovably con� gured connections are relevant.

Edge and element spacingThe distance of the structural component axis of the Schöck Isokorb® type RKS and type RQS to the edge of the structural compo-nent must be at least 190 mm, the axis-to-axis distance between between each other may not be less than 340 mm.

Installation tolerancesDue to the construction, only tolerances in the vertical direction can be balanced out via the Schöck Isokorb® type RKS/RQS with the assembly of the steel beams. The tolerance is: +10 mm vertical and ±0 mm horizontal. The Isokorb® types RKS/RQS must therefore must be placed according to precise measurement details.

The � rm entrusted with the production of the subsequently mortared-in slab connections is to be informed of the accuracies in the implementation plans by the structural engineer. In order to enable the functionally correct connection of the shell with the steel structure without adjustment and reworking, the observation of the tolerances must be be checked by the building supervision and taken inzo account in the steel structure.

Tip:A start with the fabrication of the new balcony (steel construction or prefabricated component) should � rst take place when the Schöck Isokorb® R types are placed and their � nal position has been determined through an accurate measurements (mm).

Veri� cation of the existing � oor for the existing loading

Required cross-section of the reinforcement in the existing � oor for the further transmission of the tension forces from the bend-ing moment (kd procedure):

d� oor = 200 – 30 – 8/2 = 166 mm (166 cm)MEd = 9.4 kNmb = 0.45 m

The impact width "b" of the � oor reinforcement is determined by the structural engineer, it may not be greater than the cen-tre-to-centre distance "a" of the Isokorb® connections.

kd = d/√ = d/√ = d/ (M√ (M√ Ed / b)kd = 16.6/√ = 16.6/√ = 16.6/ (9.4 / 0.45)√ (9.4 / 0.45)√kd = 3.63ks = 2.39 (from kd table for rectangular sections without compression reinforcement for bending with longitudinal force and concrete strength C20/25)as = ks · MEd / d as = 2.39 · 9.4 / 16.6as = 1.35 cm²/0.45 m

as,req = 1.35 cm²/0.45 m ≤ as,prov = 1.51 cm²/0.45 m → (R335: 3.35 cm²/m · 0.45 m) √In the case as,req > as,prov, reduce loading and / or cantilever length lk reduce to as,req ≤ as,prov.

The available bonding length lv = 755 mm of the tension bars type RKS14 results from taking as a basis the maximum anchoring and/or lap length according to DIN EN 1992-1-1 (EC2) and DIN EN 1992-1-1/NA (NAD to EC2), a concrete cover c1 = 30 mm and stain-less steel thread length on c1 = 60 mm of the front face of the � oor as well as a maximum bar spacing of the tension bars of 8 ⌀s.

lv = l0 + c1 + 4 ⌀s

lv = 639 mm + 60 mm + 4 · 14 mm

With an exceeding of the spacing of the tension bars of 8 ⌀s the lap length of the � oor and Isokorb® reinforcement according to DIN EN 1992-1-1 (EC2), Section 8.7.3 and DIN EN 1992-1-1/NA (NAD to EC2), NCI to 8.7.3 must be checked.

Already during planning, watch out for con� ict between the Isokorb® bars and the existing � oor reinforcement.

The existing � oor cannot be toughened with the Isokorb®.

Installation details

The installation of the Schöck Isokorb® R should take place in close coordination with the architect and structural engineer.

The Schöck Isokorb® type RKS installation instructions are to be observed.1. Installation instruction without text (available on all Isokorb® R types)2. Installation instruction with written installation details (simply supplied with every delivery)

The position and spacings of the existing reinforcement are to be checked (in case not known).

The position and spacings of the existing electrical lines and sanitary pipelines are to be checked (in case not known).

The front face of the existing � oor in the area of the connection of the Schöck Isokorb® R is to be formed asi rough or toothed (de-pending on Isokorb® type).

The implementation of the reinforcement connections with grouting mortar according to approval document Z- 21.8-2064 or Z-21.8-1874 can take place only through � rms with qualifying examination.

The Hilti HIT-RE 500 V3 setting instruction "Retrospective reinforcement connection using Hilti HIT-RE 500 V3" or the assembly in-struction "Reinforcement connection using � scher FIS EM" are to be observed. (Permitted drilling methods are hammer or diamond drilling, in each case using drilling aid.)

The appropriate Schöck Isokorb® R drilling template is to be used.

If existing reinforcement is met during drilling, the drilling is to be discontinued. The mis-drilling (drill hole diameter d0) is to be grouted using HIT-RE 500 V3 or FIS EM and a new drill hole is to be created with a clear separation of at least 2d0.

With the � lling of the grouting joint with PAGEL VERGUSS V1/50 grouting concrete the DAfStb Directive "production and applica-tion of cement-bound grouting concrete and grouting mortar" is to be observed.

Important:Design-related, with the assembly of the steel girder, only tolerances in the vertical direction can be compensated via the Schöck Isokorb® type RQS. The tolerance is: +10 mm vertical and ±0 mm horizontal. The Isokorb® type RKS therefore must be placed ac-cording to precise measurement details.
