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.

5. USER INSTRUCTIONS
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 1991-1-5.
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-1992-1-1 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.

Base bolt position tolerance is in accordance with the user guide for the RPP and RPP-E base bolts.
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
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 7444.
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 non-shrinkage type and with strength greater than the weakest of the concrete structures that are connected together with the bolt and shoe assembly.
