(10) In FIG. 1, the components are illustrated that are needed for the production of an assembly 10 for a line penetration through a side wall or ceiling in a building, which is illustrated in the produced state in FIG. 3 according to a first embodiment.

(11) The components are a fire-protection mat 12, which in the embodiment shown is rolled up on a core and delivered to the construction site. The structure of fire-protection mat 12 will be explained later with reference to FIG. 2.

(12) A further component of assembly 10 is a mechanical positioning element 14, which is constructed separately from fire-protection mat 12 and in the embodiment shown is constructed as a hook or angle element.

(13) Mechanical positioning element 14 is a mechanically stable element, which is formed from a plastic or a material and accordingly has a corresponding inherent rigidity.

(14) As is apparent from FIG. 1, positioning element 14 has a joining region 16, via which the positioning element can be fastened on fire-protection mat 12, as will also be described hereinafter. Furthermore, positioning element 14 has a positioning portion 18, via which positioning element 14 can be fastened to a wall or to the formwork. For this purpose, an opening 20 through which a fastening means such as a screw or a nail can be guided is provided in positioning portion 18.

(15) Joining region 16 and positioning portion 18 are preferably constructed in one piece together with one another and/or disposed at right angles to one another.

(16) Furthermore, positioning portion 18 may be provided with a reinforcing structure, which is formed by embossings 22, ribs and/or indentations.

(17) With these two components, i.e. fire-protection mat 12 and positioning element 14, it is possible to produce assembly 10 illustrated in FIG. 3, as will also be explained hereinafter.

(18) The structure of fire-protection mat 12 is evident from FIG. 2, since fire-protection mat 12 is shown there in a sectional diagram.

(19) Fire-protection mat 12 is provided with a flexible carrier element 24, which in the embodiment shown consists of a foil. The foil of carrier element 24 is a plastic foil or a metal foil.

(20) On the inside of carrier element 24, a fire-protection tape 26 joined to carrier element 24 is provided. Fire-protection tape 26 is disposed on an end region 28 of carrier element 24, precisely on a rim 29 of carrier element 24, and extends transversely relative to its rim 29 only over a certain subregion of carrier element 24, for example over at most 20% of the axial length L of carrier element 24. However, fire-protection tape 26 runs over the entire width (perpendicular to the drawing plane) of carrier element 24.

(21) It is already apparent from the perspective diagram of the rolled-up fire-protection mat 12 in FIG. 1 that fire-protection tape 26 is disposed only in an end region 28, i.e. on rim 29 of carrier element 24.

(22) In addition, a strip element 30 capable of sealing against smoke gas and water is fastened on fire-protection tape 26 as lamination on the inside of fire-protection tape 26. Strip element 30 may be constructed from a foam material, which is especially well suited for sealing against smoke gas or water.

(23) Fire-protection tape 12 therefore conforms with the requirements for fire-protection approval by the ETA and UL. In addition, imperviousness to smoke gas is assured.

(24) In contrast, fire-protection tape 26 is produced from an intumescent material and preferably is formed continuously or without interruptions on rim 29 of carrier element 24.

(25) With the components shown in FIGS. 1 and 2 and described in detail in the foregoing, assembly 10 shown in FIG. 3 is produced as explained hereinafter.

(26) Fire-protection mat 12 is first unrolled from the core and then appropriately cut to length for the size of the line penetration to be produced.

(27) Then the fire-protection mat 12 is bent into circular shape, so that a substantially cylindrically shaped fire-protection mat 12 is formed and the two rims 32, 34 of cut-to-length fire protection mat 12 are opposite.

(28) Hereby rims 32, 34 of fire-protection mat 12 fit tightly together. In the circularly shaped state of fire-protection mat 12, the two opposite rims 32, 34 are joined to one another via a joining means.

(29) The opposite rims 32, 34 may be joined to one another via an adhesive. Alternatively, the rims 32, 34 fitting tightly together may be welded to one another. Such a joint is shown in the embodiment of FIG. 3.

(30) The joining means may also be at least one separate or several separate adhesive strips 36, as also follows from the second embodiment illustrated in FIGS. 5 to 8.

(31) After fire-protection mat 12 has been bent into circular shape and the opposite rims 32, 34 of fire-protection mat 12 have been joined to one another, a fire-protection module 38 is created.

(32) Flexible carrier element 24 then forms a sheath, which serves for stabilization of the entire assembly 10. Correspondingly, the outside of flexible carrier element 24 forms the outside of assembly 10, while in contrast the space surrounded by it serves as the line penetration when assembly 10 is cast in place.

(33) After fire-protection module 38 has been produced, i.e. fire-protection mat 12 has been bent into circular shape and rims 32, 34 have been joined to one another, the at least one mechanical positioning element 14 constructed separately from fire-protection mat 12 is fastened on circularly shaped fire-protection mat 12 or on fire-protection module 38.

(34) Alternatively, the at least one mechanical positioning element 14 may also be attached firstly to cut-to-length fire-protection mat 12, which is then bent into circular shape in order to construct fire-protection module 38.

(35) In the embodiment shown, several positioning elements 14 are fastened to circularly shaped fire-protection module 38 over the circumference thereof. Hereby assembly 10 can be fastened better to a wall or to formwork.

(36) Positioning elements 14 may be adhesively bonded with, plugged into, clipped onto fire-protection module 38 or hooked onto it. Depending on how positioning elements 14 are fastened on fire-protection module 38, fire-protection mat 12 is provided with corresponding receiving elements for positioning elements 14.

(37) Positioning elements 14 are fastened on the outside of fire-protection module 38, especially of carrier element 24, i.e. on the side of carrier element 24 opposite fire-protection tape 26.

(38) Fire-protection tape 26 as well as strip element 30 are associated with the inner side of fire-protection module 38, while in contrast positioning elements 14 are disposed on the opposite outer side of fire-protection module 38 or of carrier element 24.

(39) It follows in particular from FIG. 4, in which the produced assembly 10 is shown in a transparent representation, that fire-protection tape 26 as well as strip element 30 disposed thereon is disposed only at one axial end 40 of assembly 10, at which positioning elements 14 are also disposed.

(40) This means that the intumescent material of fire-protection tape 26 is disposed in the region via which assembly 10 is fastened on a wall or on formwork. The costs of production of assembly 10, especially of fire-protection mat 12, may be correspondingly reduced, since the relatively expensive intumescent material is used only where an interface is disposed between a room and the wall.

(41) Since fire-protection mat 12 is cut to length on site and positioning elements 14 are attached to fire-protection mat 12 on site, the assembly can be produced in flexible manner on site. No great planning is needed for this purpose and the risk that a delay will occur during the construction phase is minimized.

(42) After assembly 10 has been produced as described in the foregoing, assembly 10 is used to produce a line penetration.

(43) For this purpose, assembly 10 is fastened via positioning elements 14 on an already existing wall or on the formwork for a future wall.

(44) The wall may generally be a side wall or a ceiling.

(45) After assembly 10 has been fastened via positioning elements 14 in an opening on the already existing wall or the formwork for a future wall, then, during casting of the opening on the outside of the assembly or during casting of the building part, i.e. the wall, fire-protection module 38 is surrounded on the outside by the cast material forming the building part, especially by concrete in the case of a concrete wall.

(46) Impervious fire-protection module 38 prevents liquid concrete from passing into the cavity that is surrounded by it and that functions as the line penetration and projects into fire-protection tape 26 as well as strip element 30.

(47) A second embodiment of assembly 10, which differs from the first embodiment to the effect that the two rims 32, 34 of the cut-to-length fire-protection mat 12 are joined to one another via separate adhesive strips 36, is shown in FIGS. 5 to 8. As soon as rims 32, 34 have been joined to one another, they constitute fire-protection module 38 in analogous manner, and so assembly 10 may likewise be used to construct a line penetration.

(48) Accordingly, an assembly 10 is created that can be used for various pipe diameters or line penetrations.
