Chapter 6Connecting inner cavity wallsto boundary wallsIn consultation with Xella,workingdrawings of walls will indicate themethod for connecting inner cavitywalls to separating walls.The connection possibilities are:constructive - straight edge- tooth structureflexible -sealThe mechanical qualities of shoved verticaljoints meet the requirements ofthe European standard. This was testedby TNO Bouw in the Netherlands.The structural engineer involved in acertain project remains responsible forthe construction. The mechanicalqualities of a vertical joint with specialties are equal to the mechanicalqualities of a tooth structure.28SILKA Calcium Silicate Elements

The inner cavity leafs shouldbe placed simultaneously with theparty walls. In simultaneous executionof party walls and inner cavity leafs,complete shells can be achieved. Anadded advantage is, that the newlybuilt walls are more stable and therefore,more resistant to gusts of wind.assembled lintelsynthetic foillengthof bearinglintel6.1.2 SILKA thin joint mortar blocks ininner leaf of cavity wallsFor smaller tighter areas and spaces,inner leaf cavity walls can also be builtwith hand size blocks.or self-supportingrecess size6.2 Lintels and frame connectionsPreferably door and window framesshould run up to the ceiling above. Ifthis is not possible, there are twoalternatives: filling the opening abovedoor and window frames with a timberpanel up to the ceiling above or havingthe lintel run across the full height.For frame and door openings, a lintelshould be used above the opening in awall. Due to the remaining, 2 mmhigh, bed joint, it is impossible to addsteel bed joint reinforcements inSILKA thin joint mortar systems.SILKA Calcium Silicate Elements29
