DEVICE FOR PASSING CONDUCT, PIPES AND / OR CABLES THROUGH A BUILDING COMPONENT

Description

Technical field

[0001] The invention relates to devices for routing lines, pipes and / or cables through building components, such as building walls and the like, and measures to prevent the passage of fire gases and smoke through such a device. Technical background

[0002] Known devices for routing pipes, tubes, and / or cables through building components generally incorporate measures to achieve the desired smoke tightness, fire gas tightness, and visual sealing or opacity. For example, brush curtains or loop curtains are known to be used for this purpose.

[0003] Good gas tightness is particularly important when using the device in healthcare facilities between rooms to prevent the spread of airborne pathogens. Gas tightness is also a crucial criterion when using the device in data centers, as controlling the airflow prevents temperature losses and enables the desired temperature regulation.

[0004] From US patent 2018264298 A1, a cable gland for passing cables and the like through a component is known. The cable gland has a rectangular cross-section with openings at its ends. Crossed brushes are arranged in the area of ​​each opening of the cable gland. Curved foam elements with intumescent material are arranged longitudinally within the crossed brushes, with the ends of the foam elements positioned on opposite walls of the cable gland. To close a longitudinal passage, the foam elements interact with trapezoidal blocks, each of which is arranged in a central area of ​​the foam elements.

[0005] With the design disclosed in US 2018264298 A1, the desired gas tightness may not be achievable, because when the pipe penetration is loaded with pipes or the like, the seal in the area of ​​the trapezoidal blocks may be undesirably weak, as there is relatively little material available for sealing against the pipes passing through the penetration. Furthermore, the flexible foam material of the blocks, which is specifically designed to achieve a good seal when the pipe penetration is loaded, may result in an undesirably weak seal when the pipe penetration is unloaded, due to the interaction of the foam blocks. The crossed brushes also cannot compensate for the desired degree of gas tightness of the pipe penetration.

[0006] The object of the present invention is to provide a device for routing lines, pipes and / or cables through a part of a building, in which the gas tightness of the device is improved. Disclosure of the invention

[0007] This problem is solved by the device for routing lines, pipes and / or cables according to claim 1.

[0008] Further details are specified in the dependent claims.

[0009] According to one aspect of the invention, a device for routing lines, pipes and / or cables through a building component is provided, comprising a housing with a housing wall, wherein the housing has a longitudinally extending axial passage channel bounded by the housing wall, which has an opening at each of its opposite ends, wherein the housing has a first wall and a second wall opposite the first wall, wherein a first sealing device with a curved shape is arranged inside the housing, the end regions of which are operatively connected to the first wall and the middle region of which extends towards the second wall, and wherein a second sealing device with a curved shape is arranged inside the housing, the end regions of which are operatively connected to the second wall and the middle region of which extends towards the first wall.and wherein the first sealing device and the second sealing device have a common extension area in the longitudinal direction of the device, wherein a sealing arrangement is provided in the area of ​​the openings of the device.

[0010] According to the invention, it is provided that the first sealing device and the second sealing device interact with each other via the central areas, wherein a third sealing device is assigned to the first sealing device in the common extension area and a fourth sealing device is assigned to the second sealing device in the common extension area, and wherein the third sealing device and the fourth sealing device interact with each other.

[0011] The present solution offers the advantage of improved gas tightness, for example against combustion gases, smoke, and even air exchange, compared to known designs. This is achieved, firstly, by the direct interaction of the curved, and in particular plate-shaped, first and second sealing elements, thus providing a large contact area between them. Secondly, the third and fourth sealing elements, located within the common area of ​​extension, improve gas tightness both when the device or pipe penetration is unloaded and when loaded with components such as pipes, tubes, cables, or the like.

[0012] Furthermore, the device according to the invention does not require manual opening or closing to allow the passage of lines, pipes, and / or cables through it. Gas passage through the device is significantly reduced not only when unloaded, but also when partially or fully loaded. This can be achieved, for example, by an elastic and flexible design of the first and second sealing devices, which are pressed against each other both when unloaded and when loaded, thus reducing or preventing gas passage in this area.

[0013] The common extension area is understood to be a region extending longitudinally along the device, resulting from the intersection of a longitudinal extension area of ​​the first sealing device and a longitudinal extension area of ​​the second sealing device. Preferably, the common extension area and the extension areas of the sealing devices are substantially identical.

[0014] The phrase "a third sealing device is assigned to the first sealing device within the common extension area" and a fourth sealing device is assigned to the second sealing device within the common extension area" means that the third and fourth sealing devices are arranged longitudinally within the device in the common extension area with a first end region facing the first and second sealing devices, respectively. It may be provided that a second end region of the third or fourth sealing device, facing away from this first end region, is located longitudinally outside the extension area of ​​the device. Preferably, the second end region of the third or fourth sealing device is also arranged longitudinally within the common extension area of ​​the device.

[0015] The third and fourth sealing devices each form a sealing plane or sealing surface, respectively, wherein the sealing plane of the third and the sealing plane of the fourth sealing device can be substantially congruent or can be at an angle to each other, preferably in the longitudinal direction of the device. Preferably, the third and fourth sealing devices together close a cross-section of the device almost completely or preferably completely when the device is unloaded. The opposing ends of the third and fourth sealing devices, or of sealing elements of these devices, can be flush with each other or, for example, interlock in a comb-like manner.

[0016] The housing of the device according to the invention preferably has a rectangular or square cross-section. The device preferably has two housing parts that can be operatively connected to one another. Each housing part may have a cross-section, in particular a U-shaped one.

[0017] In an advantageous embodiment of the invention, the third and / or fourth sealing device is connected to the first and / or second sealing devices, respectively. This achieves a complete seal of the device's cross-section by the third and fourth sealing devices in a structurally simple manner. Furthermore, assembly is simplified because the third and / or fourth sealing devices can be connected to the respective sealing devices before the first and / or second sealing devices are mounted to the respective housing part.

[0018] The third and / or fourth sealing device is preferably connected to the first or second sealing device, respectively, by means of an adhesive bond or a welded connection. This ensures a secure and reliable connection.

[0019] It may be provided that the third and / or fourth sealing device is connected to the first wall and / or the second wall, respectively, by means of a retaining device. In this way, flexible positioning and orientation of the third and fourth sealing devices can be achieved, whereby the position and orientation of the third and fourth sealing devices remain unchanged, at least in the area of ​​their arrangement on the respective wall, whether the device is loaded or unloaded.

[0020] In an advantageous embodiment of the invention, the retaining device for securing an end region of the first or second sealing device is integrated into the first or second wall, respectively. This allows the retaining device already provided for securing an end region of the first or second sealing device to also be used for securing the third or fourth sealing device, eliminating the need for a separate component. Furthermore, the third or fourth sealing device can be secured to the wall of the device in a single step along with securing the end region of the first or second sealing device.

[0021] Particularly good sealing of the device is achieved if a fifth sealing device is assigned to the first sealing device in the common area of ​​extension, and a sixth sealing device is assigned to the second sealing device in the same area of ​​extension, wherein the fifth and sixth sealing devices interact with each other. Preferably, the fifth and sixth sealing devices are arranged on a longitudinally opposite side of the central areas of the first and second sealing devices than the third and fourth sealing devices.

[0022] In an advantageous embodiment of the invention, further sealing devices comparable to the third to sixth sealing devices can be provided, particularly in the longitudinal direction of the device, offset from the other sealing devices in order to further improve sealing.

[0023] It may be provided that the third and / or the fourth and / or the fifth and / or the sixth sealing device has at least two sealing elements, in order to achieve a further improved seal, in particular. The sealing planes of the individual sealing elements may be arranged parallel to each other or at an angle to each other. Furthermore, the sealing planes of the individual sealing elements may be arranged perpendicular to the longitudinal direction of the device or at an angle to the longitudinal direction.

[0024] In an embodiment of the invention that is advantageous for achieving improved gas tightness, the third sealing device and / or the fourth sealing device and / or the fifth sealing device and / or the sixth sealing device each have, particularly in the area of ​​the arrangement on the first sealing device or the second sealing device, folded sealing elements, wherein the two end regions of the sealing elements are arranged flush with each other.

[0025] To improve sealing in a partially or fully occupied state of the device, the third, fourth, fifth, and / or sixth sealing device may each have sealing elements folded over, particularly in the area of ​​their arrangement on the first or second sealing device, respectively, wherein the two end regions of the sealing elements are offset from each other. Alternatively, two separate sealing elements may be provided, the end regions of which are offset from each other on the side facing away from a support.For example, if the sealing elements are designed as brushes, this means that when the device is loaded accordingly, only the brushes of the sealing element with a larger extension are deformed in a V-shape through the line, pipe or the like, and the other brush remains unchanged with a high sealing effect compared to the unloaded state.

[0026] In an advantageous embodiment of the invention, the first sealing device and the second sealing device are designed as foam elements. The material properties of the foam can be selected such that a particularly good seal is achieved in both the unloaded and loaded states of the device. It can also be provided that the foam has intumescent properties.

[0027] The third and / or fourth and / or fifth and / or sixth sealing device, or the respective sealing elements, can be designed with lamellae, brushes, bristles, strips, bands, or hose elements, each forming a sealing plane or sealing surface. The sealing elements are preferably flexible and / or elastic, with the width of the sealing elements preferably being many times smaller than the length of the sealing elements in the direction of extension and preferably also many times smaller than the length of lines, pipes, cables, or the like passing through the device.

[0028] The third sealing device and / or the fourth sealing device and / or the fifth sealing device and / or the sixth sealing device or the respective sealing elements may be made of plastic, in particular polyamide, nylon or polyester, rubber, for example rubber or EPDM, and / or biological material, in particular horsehair or pig bristles.

[0029] To further improve gas tightness, a sealing arrangement can be provided in the area of ​​each opening of the device. These sealing arrangements can be designed similarly to the third to sixth sealing devices and, in particular, each seal a complete cross-section of the device when unloaded. The respective sealing arrangement can, in particular, comprise several sealing elements, which are arranged parallel to each other and extend in a main direction. Furthermore, another sealing arrangement can be provided in the area of ​​each opening. This additional sealing arrangement can, in particular, be designed with sealing elements that extend in a main direction and are at an angle to the sealing element of the sealing arrangement, preferably at an angle of approximately 90°.

[0030] To ensure a secure closure of the device in the event of a fire and to prevent the transmission of flames between the openings for as long as possible, at least one intumescent element can be provided. The intumescent element can be a separate component, for example, one connected to the housing. If separate intumescent elements are provided, the sealing devices can be advantageously optimized with regard to material selection to achieve the best possible seal against gases and the like. Alternatively or additionally, a sealing device can also have intumescent properties.

[0031] Further advantages will become apparent from the following description of the figures. The figures illustrate exemplary embodiments of the present invention. The figures, the description, and the claims contain numerous features in combination. A person skilled in the art will expediently consider the features individually and combine them into meaningful further combinations. Brief description of the drawings

Description of embodiments

[0034] Figs. 1 to 3show a device 1 for passing one or more lines, pipes, cables or the like, such as power lines, water lines, gas lines and the like, through a part of a building, such as a building wall, a ceiling and a floor.

[0035] Device 1 does not require manual opening or closing to guide cables or the like through it. These can be guided through device 1 without any further measures.

[0036] The device 1 is in the present case designed with two parts 3, 4 each having a substantially U-shaped cross-section, which according to Fig. 1The parts 3 and 4 can be detachably arranged one another. The first part 3 and the second part 4 are essentially identical in design. When parts 3 and 4 are connected, the device 1 forms an axial passage 6 extending in the longitudinal direction L, which extends from a first axial end 10 to a second axial end 11 and has an opening 12, 13, at least in the region of the ends 10 and 11, that is open enough for conduits or the like.

[0037] In alternative designs, the device can also be made in one piece.

[0038] The device 1 comprises a housing 8 with a housing wall 9, the housing wall forming the axial passage 6 and defining an interior 14 of the device 1. The housing 8 has a substantially rectangular cross-section, which, in the assembled state of the device 1, is formed by four walls 16, 17, 18. A first wall 16 abuts a second wall 17. The further walls 18, each formed from a wall segment of the first part 3 and a wall segment of the second part 4, are again opposite each other and connect the walls 16 and 17.

[0039] Since the first part 3 and the second part 4 are essentially comparable, the following section will refer to the one in Fig. 3 The first part 3, shown in isolation, is described as representative of the second part 4.

[0040] The first part 3 has a first sealing device 22, which here is implemented with a plate-shaped foam element 23. The plate-shaped foam element 23 is bent transversely to the longitudinal direction L, so that a first end region 24 of the plate-shaped foam element 23 and a second end region 25 of the plate-shaped foam element 23, opposite the first end region 24, are each arranged in the region of the first wall 16. For this purpose, a retaining device designed as a retaining clip 27 or 28 is provided, by means of which the end regions 24 and 25 of the foam element 23 are fixed to the first wall 16. A central region 26 of the foam element 23, arranged between the end regions 24 and 25, extends in the assembled state of the device 1 from the first wall 16 towards the second wall 17 into the interior 14.

[0041] In addition to the version shown with a curved, plate-shaped foam element, it is also possible to use a pre-shaped foam element, which may, for example, have a similar curved shape to the foam element 23 or be trapezoidal.

[0042] In the present case, within a longitudinal extension 30 of the foam element 23, between the end regions 24 and 25, two intumescent elements 37, 38 are connected to the first wall 16, which are intended to seal the interior space 14 in the event of a fire. Alternatively or additionally, further intumescent elements can also be arranged, for example in the axial end regions 10, 11 of the device 1.

[0043] In the present case, the extension area 30 of the foam element 23 of the first part 3 in longitudinal direction L corresponds to an extension area 30 of the foam element 23 of the second part 4, so that the common extension area 30 in longitudinal direction L corresponds to the individual extension areas 30.

[0044] In alternative designs, the extension areas of the foam elements of the individual parts can differ from each other, whereby a common extension area is defined by an intersection of the extension areas of the individual foam elements in the longitudinal direction L.

[0045] As in Figs. 1 to 3As can be seen in simplified terms, in the area of ​​the axial ends 10, 11 of the device 1 two sealing arrangements 32, 33, 34, 35 are provided, which here each form a sealing plane perpendicular to the longitudinal direction L and which each are designed with a plurality of immediately adjacent, elongated sealing elements 26.

[0046] The sealing elements 26 have a substantially circular cross-section, are flexible and elastic, and have a longitudinal extent that is many times greater than the cross-section of the sealing elements 26. Here, the sealing elements 26 are designed as elastic lamellae with a plastic fiber made of polypropylene or polyethylene; however, in alternative designs, they can also be designed as brushes, bristles, strips, tapes, hose elements, or the like, and can incorporate other materials such as metal, rubber, biological materials, or the like.

[0047] The sealing elements 26 can also be made of woven, non-woven, or paper materials that are flexible, conform well to the outer surface of a conduit or the like guided through the device 1, and exert an elastic force on the outer surface to ensure the tightest possible seal in the area around the outer surface of the conduit. The sealing elements 26 can further comprise an intumescent material and, for example, be coated with or enclose an intumescent material, and in particular comprise paper provided with an intumescent material.

[0048] The sealing elements 26 of the first sealing arrangement 32 run perpendicular to the sealing elements 26 of the second sealing arrangement 33. Analogously, the sealing elements 26 of the third sealing arrangement 34 and the fourth sealing arrangement 35 are designed in the same way, and are arranged in the region of the second axial end 11 of the device 1.

[0049] If a line, pipe, cable or the like is passed through the device 1, the sealing elements 26 of the sealing arrangements 32, 33, 34, 35 are bent over in such a way that they rest against a lateral surface 5 of a line 2 passed through the device 1 and thereby seal against the passage of fire gases and smoke and also achieve a certain degree of opacity.

[0050] In Figs. 1 to 3Furthermore, a third sealing device 40, a fifth sealing device 42, a seventh sealing device 44, and a ninth sealing device 46 are visible, each arranged on the first sealing device 22. Similarly, a fourth sealing device 41, a sixth sealing device 43, an eighth sealing device 45, and a tenth sealing device 47 are arranged on a second sealing device 31, which is located on the second part 4. All sealing devices 40 to 47 are arranged entirely within the common extension area 30.

[0051] The sealing devices 40, 42, 44, 46 assigned to Part 3 are described below as representative of the sealing devices 41, 43, 45, 47 assigned to Part 4.

[0052] The sealing devices 40, 42, 44, 46 each have a plurality of sealing elements 48, which can be designed similarly to the sealing elements 36. Preferably, the sealing elements 48 are designed as bristles of a brush, wherein the bristles 48 of the brush, particularly in the unloaded state of the device 1, have a common longitudinal direction. In this case, the longitudinal direction of the bristles is not perpendicular to the longitudinal direction L of the device 1, but forms an angle 50 with a transverse plane Q perpendicular to the longitudinal direction L, which can be, for example, between 0° and 45°, for example, approximately 30°.

[0053] The bristles 48 of the brushes are each arranged on a retaining element 52, by means of which the brushes are directly attached, in particular glued, to the first foam element 23. In this case, the third sealing element 40 and the fifth sealing element 42 are arranged on one side of the central region 26 of the foam element 23 facing the first opening 12 of the device 1, and the seventh sealing element 44 and the ninth sealing element 46 are arranged on one side of the central region 26 of the foam element 23 facing the second opening 13 of the device 1. The length of the sealing elements 48 of the fifth sealing element 42 and the seventh sealing element 44, which are arranged closer to the central region 26 of the foam element 23 than the third sealing element 40 and the ninth sealing element 46, is shorter than the length of the sealing elements 48 of the third sealing element 40 and the ninth sealing element 46.

[0054] The sealing elements 48 of the interacting sealing devices 40 to 47 of the first part 3 and the second part 4 interlock in a comb-like manner when the unloaded device 1 is assembled. In alternative embodiments, the end regions of the sealing elements of the interacting sealing devices may also be flush with each other when the device 1 is unloaded.

[0055] As in Fig. 1 As can be seen more clearly, in the unloaded state of the device 1, the cooperating sealing elements 48 of the sealing devices 40 to 47 interlock in a comb-like manner. In addition, the central areas 26 of the foam elements 23 lie against each other over a certain extension in the longitudinal direction L of the device 1, so that a good gas tightness is achieved in the unloaded state of the device 1.

[0056] In loaded condition according to Fig. 3In addition to the sealing arrangements 32 to 35, the area of ​​the foam elements 23 and the area of ​​the sealing devices 40 to 47 are also sealed against the line 2 through the device 1, and gas passage is reliably prevented or greatly reduced.

[0057] In Figs. 4 to 6 Alternative devices 60, 70, and 80 are shown, whereby only the differences from device 1 will be discussed below, and otherwise reference is made to the descriptions of device 1. Devices 60, 70, and 80 are described in Figs. 4 to 6 Only the first part 3 is visible in each case.

[0058] In the device 60 according to Fig. 4A third sealing device 62 and a fifth sealing device 63 are provided, each arranged in an end region 24 or 25 of the first sealing device 22, respectively. In contrast to device 1, the third sealing device 62 and the fifth sealing device 63 are not directly connected to the foam element 23, but are arranged on a retaining device 64 or 65, respectively. This results in a particularly robust fixing of the sealing devices 62 and 63.

[0059] Furthermore, the retaining devices 64, 65 are comparable to the retaining clips 27, 28 of the device 1 for securing the end regions 24, 25 of the foam element 23 to the first wall 16 of the first part 3. In addition, the retaining devices 64, 65 each have a region for arranging the sealing elements 66.

[0060] The sealing elements 66 can be designed similarly to the sealing elements 48, but due to their arrangement near the end regions 24 and 25 of the foam element 23, they have a greater length than the sealing elements 48. The sealing elements 48 extend at least to the height of the first part 3, and in particular into the second part 4, so that reliable interaction and a good seal are achieved in conjunction with the corresponding sealing elements of the second part 4. In contrast to the sealing elements 48, the sealing elements 66, with their end regions facing away from the holding devices 64 and 65, are positioned further away from the respective associated opening 12 and 13 than the areas of the sealing elements 66 arranged on the respective holding devices 64 and 65. The sealing elements 66 are thus located further away from the nearest opening 12 and 13.13 viewed in the longitudinal direction L starting from their housing-side fixing in the direction of the respective other opening 13 or 12 inclined.

[0061] All sealing devices 40 to 47, 62 and 63 can, for example, be found in the Fig. 7 and Fig. 8 It must be carried out in the manner shown.

[0062] The third sealing device 62 is located closer to Fig. 7 The sealing elements 66 are, for example, made with horsehair which is bent or deflected in the area of ​​the holding device 64 in such a way that all end areas 67 of the sealing elements 66 lie essentially in one plane and form an almost flat surface.

[0063] At the in Fig. 5 The sealing devices 72 and 73 of the device 70 shown are as shown in the detailed illustration in Fig. 8The end regions 76, 77 of the sealing elements 74 of the sealing devices 72, 73 are offset from each other and thus extend unequal distances from the holding device 64 or 65. This allows for a particularly good seal of the passage channel 6 even with a low load on the device 70.

[0064] At the in Fig. 6 The device 80 shown is an alternative to the third sealing device 62 according to Fig. 4 A third sealing device 82 and a fifth sealing device 83 designed as an alternative to the fifth sealing device 63 are provided.

[0065] The third sealing device 82 and the fifth sealing device 83 differ from the third sealing device 62 and the fifth sealing device 63 in that they each have two brushes 84, 85 and 86, 87 respectively, which are each connected to the holding device 64 and the holding device 65 respectively. The brushes 84 to 87 each have sealing elements 88 which are designed similarly to the sealing elements 66, wherein a sealing plane or sealing surface of the sealing elements 88 of the brush 84 or 87 has an angle 89 with respect to a sealing plane or sealing surface of the sealing elements 88 of the brush 85 or 86 respectively. This results in improved sealing in the area of ​​pipes and the like that guided through the device 80.

[0066] All sealing devices 62, 63, 72, 73, 82, 83 of the in Figs. 4 to 6The devices 60, 70, 80 shown are arranged completely in the longitudinal direction L within the common extension area 30. For the assessment of whether the respective sealing device 62, 63, 72, 73, 82, 83 is arranged within the common extension area 30, only the respective sealing device 62, 63, 72, 73, 82, 83 is relevant, without the respective holding device 64, 65, 74, 75 provided for its arrangement.

[0067] With the devices 1, 60, 70, 80 described in more detail above, a significant airflow and thus also a transfer of smoke and gas from one side of the device 1, 60, 70, 80 to the other side of the device 1, 60, 70, 80 through the passage channel 6 is significantly reduced both in the unloaded state of the device 1, 60, 70, 80 and in the loaded state of the device 1, 60, 70, 80, and in addition, good opacity is achieved.
