Building part unit e.g. slab, protection device, has lamination body and/or polymer compound guided under prevention of side-deflection, bulge deformation and disintegration during expansion and/or intumescence along guiding unit
Building part unit e.g. slab, protection device, has lamination body and/or polymer compound guided under prevention of side-deflection, bulge deformation and disintegration during expansion and/or intumescence along guiding unit
The device has a fire protection sleeve (2) with a lamination body (21), made of a polymer material and arranged on a housing (20). The lamination body and/or a polymer compound are guided under prevention of side-deflection, bulge deformation and disintegration during an expansion and/or intumescence along an expansion-guiding unit (4). The polymer compound expands by the effect of heat in case of fire from a building.
