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.

A fire protection element is useful for the separation of openings passing through walls or ceilings, in particular of line passages. The fire protection element has a molded part made from intumescent material with a plurality of through-openings for the passage of lines which extend in particular parallel to each other from a first side to an opposite second side of the fire protection element. In each case, the through-openings for the passage are tightly sealed relative to flue gas by a membrane.

A feedthrough module for cables, cable bundles, cable trays, pipes, pipelines, empty pipes and/or combinations thereof contains hardwood, softwood or mixtures thereof and is intended for installation in a tested and/or approved wooden wall and/or wooden ceiling construction in buildings. The tested and/or approved wooden wall and/or wooden ceiling construction has an equal or lower burn rate than the feedthrough module. The feedthrough module has a cuboid body having edge lengths a, b, c, wherein c represents the edge length corresponding to the installation thickness (D) of the feedthrough module, and wherein the feedthrough module has a nominal burn rate of 0.7 mm/min or less.

A cap for a tubular sleeve having a cylindrical wall extending along a longitudinal axis for forming a passage through a concrete structure. The sleeve has radially extending ridges separated into segments with a channel parallel to the longitudinal axis. The channel has a circumferential width W. The ridges spaced apart a distance Z along the longitudinal axis. The sleeve having an inner diameter D. The cap has a cap element and a positioning tab. The cap element has a circular outer periphery with a flat top surface and a flange having a bottom end, and the tab extends inwardly from the bottom end and has a bottom surface that is orthogonal to the longitudinal axis. The tab has an inner surface that is inclined at an acute angle to the bottom surface. The tab has a width smaller than W and an axial length smaller than Z.

There is provided a casing assembly for a gas turbine engine comprising: a casing and electrically conductive intumescent material extending around the casing. The intumescent material is being activatable in response to electrical current to expand. The casing assembly comprises an electrical activation line extending around the casing to activate the intumescent material. The activation line extends in a pattern such that an activation area which circumscribes the activation line has an axial extent of at least 50% of the casing and a circumferential extent of at least 50%, to thereby activate the intumescent material at multiple locations over a corresponding area of the casing.

A method can be used for fire-resistant sealing of an opening in a wall or ceiling, through which a line is passed. The method involves cutting a strip-shaped fire protection bandage to a length corresponding to a circumference of the line, with or without an overlap. The fire protection bandage contains fire-retardant and/or intumescent material. The method then involves placing the cut-to-length fire protection bandage around the line, to form a layer which only partially protrudes outward from the opening. The method further involves annularly applying a putty to part of the fire protection bandage protruding from the opening, to form a putty ring of a slightly larger outer diameter than the opening diameter, such that the putty ring closes the opening and extends slightly beyond the edge. The method finally involves pressing the putty ring against the fire protection bandage and the opening edge, to seal the line feedthrough.

A flame-retardant unit of the present invention includes a sticky coating and an outer layer. The sticky coating is made by a calendering process and made up of a mixture of a gel, a macromolecule material, a first additive and a second additive. The gel is made of silicon as a pure mixture without including any bridging agent. The macromolecule material, the first additive and the second additive are respectively disposed in the gel. The outer layer is disposed on a side of the sticky coating to provide a side of the flame-retardant unit with viscosity. The flame-retardant unit is made by means of the calendering process. The macromolecule material, the first additive and the second additive can be distributed homogeneously in the sticky coating, which provides the flame-retardant unit with stability and favourable effect on avoiding flame propagation and explosion, as well as on uniform heat transfer and dissipation.

A fire protection device is useful for sealing through-openings in wall or ceiling elements made of wood or a similar material, in particular for sealing line or pipe feedthroughs. The fire protection device has a main body and at least one expansion body which is attached to an end face of the main body and contains an intumescent material. Also useful is a fire protection assembly.

An improved fire-blocking gasket profile for a fire-rated joint, such as a head-of-wall assembly. Fire-rated joints are aimed at inhibiting or preventing fire, heat, or smoke from leaving one portion of a building and entering another portion of a building. Fire-rated joints can also accommodate movement between adjacent building structures, such as between a ceiling and the top of a wall. The improved fire-blocking gasket profile includes a first layer formed of an intumescent material, a second layer formed of a foil lining and a third layer formed of the vinyl profile. The vinyl profile includes an air gap with the intumescent material positioned therein. A vertical portion of the vinyl profile is positioned between a header track and a wallboard in the fire-rated joint. A horizontal portion of the vinyl profile is positioned at least partially within a deflection gap and sealingly engages with the ceiling.

A method can produce an assembly for a line penetration. The method includes: (a) cutting a fire-protection mat forming a fire-protection module to length appropriate for the size of the line penetration, where the fire-protection mat has a flexible carrier element, on at least one end region of which a fire-protection tape of an intumescent material is fastened, (b) bending the fire-protection mat into a circular shape and joining opposite rims of the fire-protection mat to one another via a joining means, so that the fire-protection tape is disposed in a region of an axial end of the circularly shaped fire-protection mat, and (c) fastening at least one mechanical positioning element constructed separately from the fire-protection mat on the fire-protection mat and which is arranged in such a way that the assembly can be fastened, via the mechanical positioning element, on a wall or on formwork.
