3 RSK-N, RSK-E Wall shoes Wall shoes are fastening components that are used with RPP and RPP-E base bolts to create tension resisting connections across joints between two precast wall elements or between precast wall element and a site cast structure. Compression stresses are transferred directly across the grout filled joint. Shear stresses along the joint are transferred by friction or by additional installed shear studs for this purpose. Tension stresses developed at the joint are transferred within the wall, via reinforcement, to the next wall joint above and below. The wall shoes are designed with matching design tension resistance of the associated RPP and RPP-E base bolts. Additional RAL washer plates are supplied with the associated wall shoes to form the connection to the matching base bolts. RSK-N RSK-E Technical Manual - RSK-N, RSK-E Wall shoes v

The wall shoes are designed with matching design tension resistance of he associated RPP and RPP-E base bolts.

Fabrication 3.1 Fabrication Method Execution Standard EN Plates Rebars Flame cut, laser or plasma cut and mechanically cut Mechanically cut Welding Hand or robot MAG-welded, class C (EN ISO 5817) In accordance with EXC 2 Surface Treatment Untreated unless agreed otherwise. NOTE. The product shall be produced clean and dry. Light surface rusting may be present at delivery of the product. The product is to be stored in dry conditions. The product may be installed with light surface rusting, and in accordance with general requirements for reinforcement bars. 3.2 Quality Control Fabrication and quality control in accordance with SFS-EN R-Group Oy internal quality control in accordance with ISO 9001 and ISO External quality control provided to R-Group Finland Oy: Inspecta Sertifiointi OY 3.3 Shoe Markings R-GROUP Oy's product identifier and date Inspecta Sertifiointi Oy's check markings 4. Resistances The tension capacities of the wall shoes, calculated in accordance with EC (EN 1992, 1993), are governed by the tension capacity of the connected RPP, RPP-E base bolt. More information is provided in the R-STEEL RPP, RPP-E base bolt user guide. Minimum concrete grade of the wall is C25/30. The anchorage length (lap length) is determined on the basis of the diameter of the anchor bar. Anchorage coefficients, lap factor 6 = 1,5, 2 = 0,7, others 1 5 = 1,0 Nominal Wall Shoe Design Tension Resistance RSK-N Shoe RAL RPP Base Bolt N Rd [kn] M16 N16 M16 62,2 M20 N20 M20 97,0 M24 N24 M24 139,4 M30 N30 M30 222,2 M39 N39 M39 386,5 Version 01/ Technical Manual - RSK-N, RSK-E Wall shoes v

User Instructions 5.1 Limits of Use The capacities of the wall shoes have been calculated for static loads. Increased load factors are to be adopted for case specific dynamic and fatigue effects. For design in accordance with the Eurocodes, the lowest operating temperature is calculated from EN Design Guidance Grout is to be applied to the joint as soon as possible after the wall element has been lifted into position. Other structures can be installed on top of the wall element after the grout has hardened. Out-of-plane (transverse) support of the wall element must always be considered carefully. The RSK-N and RSK-E wall shoes are to be installed in the middle of the precast wall element, and their anchor bars are to be tied to the reinforcement of the wall. Minimum wall thickness, and associated minimum concrete cover to the anchor bars of the wall shoe, are given in the table below. Minimum wall thickness is determined taking into account minimum requirements presented in EN for concrete cover to the anchor bars of the wall shoe. The wall shoes are designed for environmental condition exposure class XC1.Design standard requirements must be carefully considered for other exposure classes, for example minimum wall thickness and concrete cover for fire and exposure classes.

Checklist prior to casting of the wall element: The correct shoe size and type has been installed in the mould The positioning of the shoe is correct Adequate tieing of the shoe into the reinforcement cage, and adequately clamped to the end plate of the mould Casting boxes are in position Checklist after casting of the wall element: Shoe position is correct, and has not moved or rotated Grouting pipe is open (if used) Casting boxes are removed Ensure that the shoe voids are clean i.e. no concrete or cement 6.1 Installation of the precast wall element The precast wall element is installed at the correct level by using packer plates. The wall element is to be temporarily support during erection, and its level and inclination checked. Before the nuts are tightened, the position of the RAL washer plate inside the wall shoe must be checked. Nuts are to be firmly tightened, for example using an impact wrench. Following tightening of the nuts, lifting connections can be disconnected and removed. Erection must follow the erection scheme that is approved by the responsible engineer. Space required for tightening the nut with an impact wrench is verified in accordance with DIN Once the wall element is set at the correct level and inclination, and the nuts are tightened, the base is to be grouted in accordance with the manufacturer's guidance. The grout must be of a nonshrinkage type and with strength greater than the weakest of the concrete structures that are connected together with the bolt and shoe assembly Technical Manual - RSK-N, RSK-E Wall shoes v
