  • Patent number: 10669710
    Abstract: A fireproof profile may be used for sealing a structural joint, in particular a connection joint between a dry wall and a ceiling. The fireproof profile includes a profiled element which has an inner face and an outer face arranged opposite the inner face and has an inner section, at least one arc section, and at least one side section. The side section is connected to the inner section via the arc section. The fireproof profile further includes at least one intumescent element made of an intumescent material. The arc section has a wall thickness which optionally differs from the wall thickness of the inner section and/or of the side section.

  • Patent number: 10663090
    Abstract: A device is useful for passing pipes or cables through an opening in a building. Said device has 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.

  • Publication number: 20190376300
    Abstract: A sealing strip is for sealing drywall connecting joints. The sealing strip has a centre web with two longitudinal edges, wherein along each longitudinal edge, a sealing profile is arranged having a first profile section, which is arranged along the allocated longitudinal edge and has a first thickness in the transverse direction of the centre web. A second profile section adjoins the first profile section, and the second profile section forms the end of the sealing profile that is remote from the centre web and has a second thickness in the transverse direction of the centre web, the second thickness being smaller than the first thickness.

  • Patent number: 9151042
    Abstract: In a ceiling passage with an opening through which a pipe extends in the vertical direction, the pipe being surrounded by a fire-prevention sleeve, the fire-prevention sleeve includes, for example, fire-prevention additives embodied in a rectangular strip. A plurality of notches are provided along only one longitudinal side of the rectangular strip. The plurality of notches are used to form flaps at a bottom edge of the rectangular strip and are bent backwards. The flaps are supported at an inner wall of the ceiling passage near a bottom of the ceiling passage.
