A fire protection sleeve segment can be arranged for a fire protection sleeve for sealing a combustible body penetrating an opening in a wall or ceiling in the event of fire. The fire protection sleeve segment contains a first housing element and a second housing element, wherein the housing elements have a boundary wall containing a contact surface and an outer surface opposite the contact surface. The two housing elements are rigidly interconnected and arranged so as to be stepped with respect to one another. An intumescent material is applied to the contact surfaces. To form a fire protection sleeve, a plurality of fire protection sleeve segments are arranged relative to one another and interconnected such that the intumescent material applied on the contact surface of the first housing element is covered, in whole or in part, by the second housing element of the respectively adjacent fire protection sleeve segment.

The invention relates to a device for passing pipes or cables through an opening in a building. Said device comprises a sleeve-like housing that has an axial passage channel that is open at its opposite ends; bristles that are mounted on the walls of the passage channel in such a way that they are opposite each other and that are extended inwards in such a way that they mesh with one another in order to close the passage channel; and flexible strips of material that are mounted in the passage channel and that are coated with an intumescent material.

A seal assembly (10) for sealing an opening (12) in a wall (14) or ceiling of a building, especially for sealing a line penetration, wherein the seal assembly (10) is able to cover the opening (12) and has a passage (32) for a line (18), has at least two disk-like seal segments (16), which together define the passage (32) at inside rim portions and in circumferential direction overlap at adjacent rims (22). A seal segment (18) for such an assembly has an elastic sealing compound (26) that is applied on a carrier film (28).

The present invention relates to a fire-protection-collar element (10) for forming a fire-protection collar (35) for closing through-passages in walls (38), ceilings and/or floors in the event of a fire. The present invention also relates to a method for forming a fire-protection collar (35) for closing through-passages in walls (38), ceilings and/or floors in the event of a fire.

A fire protection element for sealing a combustible body which penetrates an opening in a wall or ceiling, in the event of a fire, contains a fire protection insert and a heat-activatable drive for the fire protection insert, wherein the fire protection insert is in an initial position within the wall or ceiling and, in the event of a fire, is moved into a use position in which the fire protection insert is at least partially outside the wall or ceiling.

The fire and smoke containment services transit unit includes a casing constructed from a material having a thermal conductivity of less than 5 watts per meter per Kelvin. The casing defines a first opening at a first end and a second opening at the second end. Intermediate the first and second end is the internal volume that is encased by the casing. The internal volume and each of the openings are sized to allow services such as cables, pipes, etc. to be threaded through the services transit unit. An intumescent material is housed centrally within the internal volume. Prior to exposure to the heat of a fire, the intumescent material maintains a slim profile. However, when the transit unit is exposed to the heat associated with a building fire, it swells and thereby seals the internal volume against the passage of fire, smoke or heated gases through the transit unit.
