In existing buildings with an AC frame structure, the infills, not being connected to the surrounding frame, are free to tip over both internally and externally during seismic movement, constituting a real hazard during evacuation.
The PALLADIO SECURITY SYSTEM anti-tip system proposed by Fornaci Calce Grigolin, to be preferably realised on both sides, consists of a pre-stretched fibreglass or basalt fibre net arranged in a diffused manner immersed in a first layer of suitable mortar based on certified NHL natural hydraulic lime, still fresh, and then fixed dry to the concrete frame by means of a system of stainless steel helical bars suitably chosen and arranged according to the design indications. The system is completed with the application of a second layer of mortar to cover the garrison.
