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 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.

An installation block for dry walls is disclosed. The installation block includes at least one through-hole for passing through a cable, pipe, or the like. The installation block also includes two installation block parts, which are joined together and have a separating plane T, which intersects with the at least one through-hole. Further, a dry wall and a method for installing an installation block are disclosed.

A fire protection module is provided for wall and ceiling openings. The fire protection module includes a sheath for insertion into the wall or ceiling opening and a flange to be placed at the wall or ceiling. The assembly of the fire protection module may be performed with few steps. For example, the sheath and the flange are embodied in one piece.

A modular frame is described for the assembly of at least one conduit at a construction part. The modular frame comprises a base plate that may be fastened at the construction part, several flange elements arranged side-by-side which may be fastened at the base plate, each comprising a sealing element, and a flat, plate-shaped intermediate element arranged between the base plate and the flange elements, which is characterized in the base plate, the intermediate element, and the flange element showing several passages to accept conduits adjusted to the diameters of said conduits.
