How to: Arcade with acoustic and thermal decoupling

Acoustic and thermal decoupling is important for quality of living when connecting multi-storey residential buildings via arcades. The impact sound insulated Egcotritt shear force dowel for the connection of the reinforced concrete slab to the shell construction combines both requirements in one component.

• The sleeve part is inserted on the slab side and concreted. Attention must be paid to the parallel alignment and fixing of the anchor body before concreting.
• The acoustic boxes responsible for the acoustic and thermal decoupling are installed in the prepared recesses and connected to the sleeve bodies on the slab side.
• The acoustic box is fixed with mortar for the load transmission and the recess is fully concreted.
• A continuous joint between the arcade slab and the wall of the building must be ensured in order to guarantee the sound decoupling.
• The thermal insulation of the joint can be executed when installing the external thermal insulation composite system.
