FIRE PROTECTION COLLAR SEGMENT AND FIRE PROTECTION COLLAR

摘要

The invention relates to a fire protection collar segment (10) for a fire protection collar (62) for sealing a combustible body (64) penetrating an opening (58) in a wall or ceiling in the event of a fire, which fire protection collar segment comprises a first housing element (12) and a second housing element (14). The housing elements (12, 14) each comprise a delimiting wall (20, 22), which has a contact surface (50, 52) and an outer surface (24, 26) opposite the contact surface (50, 52). The two housing elements (12, 14) are fixedly connected to one another and are in a stepped arrangement relative to one another. An intumescent material (54, 56) is applied to the contact surfaces (50, 52). In order to form a fire protection collar, several of the fire protection collar segments (10) are arranged relative to one another in such a way and connected to one another in such a way that the intumescent material (54) applied to the contact surface (50) of the first housing element (12) is completely or partially covered by the second housing element (14') of the adjacent fire protection collar segment (10').
