- wherein the fire protection insert is arranged so as to be movable in the longitudinal direction of the opening.
1 more element
15:
- The fire protection element according to claim 14, wherein the fire protection insert is located in a starting position within the opening and, by the movement device, can be moved into an end position in which the fire protection insert is located at least partially outside of the opening.
16:
- The fire protection element according to claim 14, wherein the fire protection insert is coupled to the movement device.
17:
- The fire protection element according to claim 14, wherein the fire protection element comprises a cladding pipe in which the movement device and/or the fire protection insert are arranged.
