DESCRIPTION OF EMBODIMENTS

[0028] FIG. 1 shows a cross-sectional diagram through a line penetration 1. Line penetration 1 is used for routing of one or more lines 4, such as power lines, water lines, gas lines and the like, for example, through a building structure part, such as a building wall, a ceiling and a floor, for example.

[0029] For this purpose, line penetration 1 is provided with a penetration element 2, which has substantially hollow-cylindrical construction and thus forms a passage opening for routing lines 4 through along a longitudinal direction L of the passage opening. The cross section of penetration element 2 may be circular or rectangular.

[0030] A retaining device 3, which in particular may be disposed in a middle region (relative to longitudinal direction L of the passage opening) of penetration element 2, is disposed in penetration element 2. Retaining device 3 is used for acting on penetrating line 4 with a retaining force that acts transversely relative to the longitudinal direction of penetrating line 4, so that this is held frictionally relative to axial displacement.

[0031] Retaining device 3 is provided with two flexible retaining elements 31, which are turned toward one another, which are deformed by the thickness of a line 4 routed through them and which exert, on penetrating line 4, a force transverse to longitudinal direction L that holds line 4 against slipping. Retaining elements 31 respectively have an elongated retaining edge 32 and in this way define a retaining region 33 extending in transverse direction Q, transversely relative to longitudinal direction L.

[0032] Furthermore, sealing arrangements 5 are disposed offset in longitudinal direction L relative to retaining device 3, in order to prevent passage of fire gases and smoke through penetration element 2.

[0033] In conjunction with FIG. 2, which shows a cross-sectional diagram along section line A-A, a possible structure of sealing arrangement 5 will be explained in more detail. Sealing arrangement 5 is provided with two sealing structures 51 situated opposite one another. Sealing structures 51 are disposed on two oppositely situated regions of the inner wall of penetration element 2 in a manner oriented in transverse direction Q. In the shown embodiment, sealing structures 51 are provided with elastic lamellas 53 directly adjacent to one another, the respective first end of which is fastened to the inner wall in question of penetration element 2, so that lamellas 53 extend into the interior of penetration element 2. The respective second ends of lamellas 53 are located in a passage region 52.

[0034] Lamellas 53 respectively have lengths such that they respectively bear on one another with or in the region of their second ends and thus prevent passage of fire gases and smoke through passage region 52.

[0035] In a portion of passage region 52 in which line 4 is routed through sealing arrangement 5, lamellas 53 are bent over in longitudinal direction L in the region of their second ends and thus bear on the shell surface of line 4 and seal it against passage of fire gases and smoke. In order to achieve reliable sealing, the width of lamellas 53 in transverse direction Q should be much smaller than the diameter (or the dimension in transverse direction) of line 4; in particular, the width of lamellas 53 in transverse direction should be smaller by the factor 5, preferably by the factor 10, than the diameter (or the dimension in transverse direction) of line 4. The thickness of lamellas 53 in longitudinal direction may amount to between 0.5 mm and 5 mm, preferably between 1 mm and 3 mm. Sealing structures 51 may comprise several arrangements of lamellas 53 disposed directly one behind the other in longitudinal direction L.

[0036] Lamellas 53 may have a rectangular cross section, so that adjacent lamellas 53 bear on one another with their side faces, in order to achieve imperviousness even relative to passage between lamellas 53.

[0037] Alternatively, lamellas 53 may also be designed as bristles with round cross sections and may have several layers in longitudinal direction L, so that in this way they form a brush structure 55. The bristles of this brush structure 55 preferably bear on one another, in order in this way to ensure adequate imperviousness relative to the passage of fire gases and smoke. In particular, the bristles of brush structure 55 may bear against one another with a packing density that is as high as possible, so that an arrangement such as illustrated by way of example in FIG. 3 is provided in a cross-sectional view relative to the direction of extension of the bristles. For this purpose, several parallel rows of bristles touching one another are respectively disposed offset relative to one another by the radius of the bristles, wherein the bristles of adjacent rows likewise bear on one another.

[0038] Lamellas 53 or the bristles are preferably formed from an elastic synthetic material. Furthermore, it is also possible to provide woven fabrics, scrims or paper materials, which are flexible, can be laid snugly on the shell surface of line 4 and if possible exert an elastic force on the shell surface, in order to ensure the best possible sealing closure in the region around the shell surface of the line. Lamellas 53 may further be provided with an intumescent material, such as be coated with an intumescent material, for example, or may enclose an intumescent material, and especially may comprise paper equipped with intumescent material.

[0039] As shown in FIG. 4, lamella arrangements 51 may also be provided with lamellas 53 of different length, so that second ends of lamellas 53 respectively situated opposite one another bear on one another at places that along transverse direction Q are offset in a direction of extension E of lamellas 53. Thereby a broadened passage region 52 is obtained. This permits better bearing on penetrating line 4.

[0040] FIG. 5 shows a cross-sectional diagram through a sealing arrangement 5 according to a further embodiment, wherein several sealing structures are provided. A first sealing structure 51 is constructed as described in the foregoing and correspondingly has a lamella arrangement of lamellas 53, which are adjacent to one another and extend in transverse direction Q of passage region 52. The second ends of lamellas 53 bear on a second sealing structure 56, which is provided with a through-going flexible sealing element having a contact face 57 extending in transverse direction Q. Passage region 52 is formed by the bearing of the second ends of lamellas 53 on contact face 57 of the through-going sealing element of second sealing structure 56.

[0041] Second sealing structure 56 is formed from an elastically deformable material, such as a foam or the like, for example, which in particular is provided with an intumescent material. The elastically deformable material of the through-going sealing element and the elastic material of the lamellas as well as their geometric dimensioning are chosen such that, when line 4 is routed through, these are forced by approximately half of their cross section into the elastically deformable material of second sealing structure 56 and thereby deform it.

[0042] During routing of a line 4, part of line 4 deforms elastically deformable through-going sealing element 56, whereas the part of the line cross section projecting out of second sealing structure 56 is surrounded by lamellas 53, in such a way that these bear with their second ends on the shell surface of line 4. In this way, sealing against fire gases and smoke can be achieved, since every part of the shell surface is in contact with a sealing structure 51.

[0043] In order to achieve improved sealing of sealing structures 51 formed with lamellas 53, the lamellas of first sealing structure 51 may be designed with changing elasticity, to the effect that the material of lamellas 53 has smaller elasticity at their fastening to penetration element 2 than at their second end. In other words, the stiffness of lamellas 53 decreases toward their second ends. Thus a penetrating line 4 deforms lamellas 53 substantially at its shell surface, wherein the bent-over portion of lamellas 53 is then in contact with the shell surface in longitudinal direction L. This permits particularly good sealing against fire gases and smoke.
