A fire protection element can be used for sealing a combustible body, which penetrates an opening in a wall or ceiling, in the event of a fire. The fire protection element has a belt- shaped carrier from the edge of which tongues protrude transversely to the longitudinal direction of said carrier. The tongues are connected to the belt-shaped carrier, at least a significant proportion of the tongues are formed of a bimetal, and the tongues can move in one direction under the effect of heat. A fire protection material is applied to at least one side of the tongues. Furthermore, a method can be used for sealing a combustible body, which penetrates an opening in a wall or ceiling, in the event of a fire.

Fire protection element having bimetal

A fire protection element contains a layered body for sealing passage openings in components, such as building components, through which lines are guided. A method can be used for producing the fire protection element and the fire protection element can be used for sealing passage openings and/or joints in components against fire and flue gases.

Fire protection element for sealing passage openings in components

A fire protection element containing a layered body can be utilized for sealing passage openings in components, such as building components, through which conduits are guided. A method can be used for producing the fire protection element. The fire protection element can be used for sealing passage openings and/or joints in components against fire and flue gases.

A composite material, a method for the production thereof, and a fire protection element containing the composite material can be utilized for the protection of passage openings in components in the event of fire, such as building parts, through which conduits are guided. The composite material can be also used as a fire protection element for sealing passage openings and/or for joints in components.

Composite material and fire protection element for sealing passage openings and joints in components

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 movement device which acts on the fire protection insert, the fire protection insert being arranged so as to be movable in the longitudinal direction of the opening.

Fire protection element

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.
