How to: Shear force transmission for load-bearing exposed precast concrete façades

How to: Shear force transmission for load-bearing exposed precast concrete façades

For optimum shear force transmission, load-bearing precast concrete sections can be connected to the internal structure using Egcobox® thermal breaks.

A reduction in thermal bridging is achieved by thermally isolating the façade components from the internal structure using the Egcobox® connecting elements. In addition, optimum shear force transmission can be secured with the statically effective Egcobox® isolating element. For a cost-effective solution, Egcobox® units can be manufactured to suit structural requirements of this type of application.

How to:

Shear force transmission for load-bearing exposed precast concrete façades
  • Development of the Egcobox® cantilever connectors as a bespoke solution for load and reinforcement layout.
  • Production of the Egcobox® units for the precast plant.
  • Assembly of the precast sections with corresponding preassembly of the Egcobox® units.
  • On-site placement of the slab formwork for the in-situ concrete floor.
  • To enable the façade panels to be installed after the frame has been cast, a recess can be created in the floor slab using Stremaform® shuttering to receive the Egcobox® reinforcement bars. Using the Stremaform® shuttering provides the characteristics of an 'indented joint' according to EC2.
  • Mounting of the façade sections – securing the position with Egcodubel shear force dowel at the bottom of the elements and with the Egcobox® units placed into the recesses in the slab - which are subsequently concreted.
