Description

[Technical field]

[0001] The present invention relates to a transit device for passing one or more cables and / or pipes through an opening in a partition. A transit device of this kind includes an extension frame having a central, axially extending opening. Such a transit device is used to pass cables and / or pipes through a wall or other type of partition. A transit device of this kind may include a mounting frame having a central, axially extending opening, which mounting frame can be connected to the partition. [Background technology]

[0002] Different types of penetration devices are used to pass cables and / or pipes through walls or other partitions. Generally, for sealed transit, some kind of seal is placed inside a mounting frame placed at the opening of the partition. One example of a seal is a number of compressible modules that receive the cables or pipes. Such compressible modules are usually received in one or more rows with a compression section in the mounting frame. The compression section compresses the compressible modules in one direction such that the compressible modules seal inwardly around the cables and / or pipes and outwardly against the inside of the mounting frame.

[0003] Penetration devices for cables and pipes are used in various environments such as cabinets, technical shelters, junction boxes, machines, etc. They are used in different industrial environments such as automotive, telecommunications, power generation and distribution, and marine and offshore. They will form a seal against fluids, gases, fire, rodents, termites, dust, moisture, etc. and may receive cables for electricity, communications, computers, etc., or pipes for various gases or liquids such as water, compressed air, hydraulic fluids, cooking gas, etc.

[0004] Various penetrations require fire protection and it is common to place some kind of fire protection material inside the penetration. The use of intumescent materials as fire protection materials is well known in the art. Intumescent materials are materials that expand when exposed to excessive heat, such as during a fire. The intumescent material may act as an insulating material for the cable in the event of a fire.

[0005] In the prior art, the penetration device comprises an extension frame with axially extending penetration openings for cables and / or pipes. One or more intumescent material strips and a number of holes penetrating the wall of the extension frame are provided in the extension frame. The holes in the extension frame located on the fire side improve the reaction time of the intumescent material, so that the intumescent material can react as soon as possible and therefore start to act as an insulator around the cables. The holes in the extension frame on the non-fire side ventilate the frame and cool the cables. Therefore, depending on which side of the wall the extension frame is located, the purpose of the holes is different.

[0006] The prior art penetration devices have a problem that they cannot be used for different applications of different types of cables and / or pipes, and therefore have a problem that the prior art penetration devices have limitations in their use and are not efficiently installed depending on the application at hand. Summary of the Invention

[0007] In view of the above, it is an object of the present invention to provide a penetration device that allows for efficient installation. According to a first aspect of the present invention, it is an object of the present invention to provide a flexible penetration device that operates in multiple applications. According to a second aspect of the present invention, it is an object of the present invention to provide a penetration device with improved fire protection.

[0008] According to a first aspect, the invention relates to a penetration device for passing one or more cables and / or pipes through an opening in a partition, the penetration device comprising an extension frame connectable to a mounting frame and / or the partition and having an axially extending penetration opening for the cables and / or pipes, the extension frame comprising a plurality of extension frame modules having a first end, a second end and an axially extending edge extending between the first end and the second end, the axially extending edge being provided with a connecting element, the extension frame modules being connectable to one another by the connecting element to form the extension frame, the first end of the extension frame module being provided with a fastening element for fastening to the mounting frame and / or the partition. Thus, a versatile modular penetration device is achieved, which can be adapted to various applications in an efficient, reliable and cost-effective manner. Moreover, the structure of the penetration device is lightweight and easy to install. The penetration device may comprise the mounting frame, the extension frame being connected to the mounting frame and / or the partition and extending axially from or away from the mounting frame.

[0009] A connecting element may be provided on each of the axially extending edges. For example, each extension frame module has three axially extending walls and four axially extending edges, two of which are free edge portions. Thus, the extension frame modules can be connected to each other. For example, the free edges of two adjacent extension frame modules can be connected to each other to form an extension frame. At the same time, the adjacent extension frames can be connected to each other. Also, the extension frame modules may be identical, which allows for simple manufacturing, low cost, and easy installation.

[0010] The connection elements may include hook portions for connection to the hook portions of adjacent extension frame modules by locking elements, such as form-fit locks in the form of strips or clips that enclose one or more connection elements of two adjacent extension frame modules. Thus, the connection elements can be easily and cheaply manufactured by folding the hook portions at the free edges and punching and folding the hook portions at the other edges. Thus, the extension frame modules can be placed on a sheet metal, such as a piece of sheet metal, by folding and punching.

[0011] Each extension frame module may be provided with one or more intumescent material strips that align with corresponding strips on adjacent extension frame modules. Thus, fire retardant transport may be achieved by the penetration device in an efficient manner. By locating the intumescent material strips adjacent to at least one row of at least partially unobstructed holes, a fast response to heat can be achieved on the fire side of the partition while venting the non-fire side for cooling. The holes in the extension frame located on the fire side improve the reaction time of the intumescent material. This allows the intumescent material to react faster and therefore begin to act as an insulator around the cables. The holes in the extension frame on the non-fire side ventilate the frame and cool the cables. Thus, the holes have a dual function and their purpose differs depending on which side of the wall the extension frame is located on.

[0012] The mounting frame may include a number of mounting frame modules connectable together to form the mounting frame, so that both the extension frame and the mounting frame may be modular for assembling a suitable penetration device.

[0013] Each mounting frame module may be provided with a removable cover that is removed prior to installation of the cables and / or pipes. The cover may prevent debris, liquids, etc. from entering the penetration device prior to installation of the cables and / or pipes. The cover may be arranged for fire protection. For example, the cover may be a fire resistant material, such as a plastic material containing a flame retardant, and may include a fiber reinforcement, such as a fiberglass reinforcement. The cover may be connected to the frame via a breakable peripheral notch, and the cover may be efficiently removed by forming a breakable diagonal and / or cross notch extending from the breakable peripheral notch to a free edge of the cover.

[0014] The extension frame is provided with a plurality of individual displacement elements displaceable from a first position to a second position, where in the first position the displacement elements extend radially inward and in the second position the displacement elements extend at least partially in a direction along the extension frame. The displacement elements provide a barrier to prevent unwanted access to the extension frame, to prevent unwanted material from entering the extension frame and to improve fire protection of the penetration device. One or more of the displacement elements can be displaced and bent, for example by hand, to facilitate attachment of the cables and / or pipes. Thus, the displacement elements may be formed of sheet metal and may be formed together with the extension frame modules, for example by bending and stamping from a single piece of sheet metal.

[0015] According to a second aspect, the invention relates to a penetration device for passing one or more cables and / or pipes through an opening in a partition, said penetration device comprising an extension frame connectable to a mounting frame and / or to said partition and having an axially extending penetration opening for the cables and / or pipes, said extension frame being provided with a plurality of individual displacement elements displaceable from a first position to a second position, in which in the first position said displacement elements extend radially inwards and in the second position said displacement elements extend at least partially in a direction along said extension frame. The displacement elements provide a barrier to prevent unwanted access to the extension frame and to prevent unwanted material from entering the extension frame. In case of fire, the pipes or cables conduct heat through the partition so that combustible material in contact with or in the vicinity of the cables or pipes in the vicinity of the partition can ignite due to the heat. The displacement elements reduce the risk of combustible material entering the extension frame. One or more displacement elements can be displaced and bent, for example by hand, to facilitate the installation of the cables and / or pipes. The displacement element may be made of sheet metal and together with the extension frame may be formed, for example, by bending and stamping from a single piece of sheet metal. The penetration device may include a mounting frame, the extension frame being connected to the mounting frame and / or the partition and extending axially from or away from the mounting frame.

[0016] A first end of the extension frame may be connected to the mounting frame and / or the partition, and a second end of the extension frame may be provided with a displacement element such that, in the first position, the displacement element at least partially blocks an axially extending opening in the second end of the extension frame.

[0017] The penetration device according to the second aspect can be combined with the embodiment according to the first aspect described above and is described in detail below with reference to the accompanying drawings. Further objects and advantages of the present invention will be apparent to those skilled in the art from a reading of the following detailed description. [Brief description of the drawings]

[0020] With reference to FIG. 1, according to one embodiment, a penetration device 10 for passing at least one cable 11 and / or at least one pipe through a partition 12 is shown diagrammatically. The penetration device 10 is arranged for passing one or more cables 11 and / or pipes through a partition 12 in the form of a wall, floor, roof or ceiling. The partition 12 is shown in FIG. 1 with dashed lines. For example, the penetration device 10 is arranged to be attached to the partition 12 including studs provided with a panel such as a building board of gypsum or wood. For example, the penetration device 10 is arranged for passing cables 11 such as cables for electricity, communication, computer, etc. or pipes for various gases or liquids such as water, compressed air, hydraulic fluids, cooking gas, other liquids or gases. The cables and / or pipes are guided axially through the penetration device 10.

[0021] The penetration device 10 of FIG. 1 is arranged to receive one or more sealing modules 13, compression sections 14 and optional stayplates 15. The sealing modules 13 may be arranged in different sizes and a plurality of different sealing modules 13 may be arranged in different configurations, which is also shown with reference to FIG. 2. For example, the sealing modules 13, compression sections 14 and stayplates 15 are of conventional type, if applicable. For example, the sealing modules 13 are resilient and include two opposing sealing halves 16, each half module 16 including a plurality of release sheets 17 arranged in a semi-cylindrical groove 18, as shown in FIG. 3. Optionally, an appropriate number of the release sheets 17 are removed to fit the sealing module 16 to the diameter of the cable or pipe, the cable 11 or pipe is placed in the half module 16 and the sealing module 13 is formed by overlapping the two half modules 16 on top of each other. For example, the compression sections 14 are of conventional wedge type.

[0022] As shown in Figures 4 and 5, the penetration device 10 includes a mounting frame 19 and an extension frame 20. The mounting frame 19 is arranged to receive one or more compressible sealing modules 13 in a central axially extending opening in which one or more cables and / or pipes are arranged. In Figure 4, said opening is covered by an optional removable cover 21, which will be described in more detail below. For example, the opening of the mounting frame 19 is arranged to be sealingly filled with the sealing module 13, one or more compression sections 14, and optionally one or more stay plates 15. For example, the mounting frame 19 is formed of a plastic material, such as a fiber-reinforced plastic material. For example, the mounting frame 19 is formed of a polyamide, such as a fiberglass-reinforced polyamide. The mounting frame 19 is therefore lightweight and suitable for mounting to a panel wall, such as a wall including girders and panels of gypsum board or similar building material.

[0023] In the illustrated embodiment, the mounting frame 19 includes a flange 22 for fastening the penetration device 10 to the partition 12, such as by screws or other conventional fastening means (not shown). For example, holes are disposed in the flange 22 for receiving the screws. The extension frame 20 may extend away from the mounting frame 19 and the partition. Alternatively, as shown in FIG. 1, the extension frame may extend through an opening in the partition 12.

[0024] In the illustrated embodiment, the mounting frame 19 is a modular mounting frame, which includes a first and a second end module 23, 24 and optionally one or more intermediate modules 25 arranged between the end modules 23, 24. For example, the first and second end modules 23, 24 each include three walls, two walls facing each other and connected to each other at one end via the other wall. For example, the first and second end modules 23, 24 are identical. The intermediate module 25 includes opposing walls connected to each other via a centrally located wall. The first and second end modules 23, 24 may be connected to each other or to the intermediate module 25 by a form-fit locking device 26, which will be described in more detail below. In FIG. 4, the end modules 23, 24 and the intermediate module 25 form two openings for cables and / or pipes, which are arranged parallel to each other in the figure and are covered by a removable cover 21.

[0025] The extension frame 20 is connected to and extends axially from the mounting frame 19. The extension frame 20 and the mounting frame 19 form an axially extending opening therethrough, and one or more cables and / or pipes may be placed into the opening through the extension frame 20 and the mounting frame 19, for example, after removing an optional cover 21.

[0026] At least one expansion material strip 27 is disposed on the inner and / or outer periphery of the extension frame 20. The expansion material strip 27 is attached to the surface of the extension frame 20, for example, by adhesive. However, such adhesives have been found to be unreliable, for example, at high temperatures. In the illustrated embodiment, the extension frame 20 is disposed with bendable tabs 28 that can be bent over the expansion material strip 27 to clamp the expansion material strip 27 in place. Thus, the expansion material strip 27 is secured by the tabs 28 without the use of adhesive. The tabs 28 are distributed along the periphery of the extension frame 20. In the illustrated embodiment, the tabs 28 are disposed in a row around the extension frame 20 adjacent to the expansion material strip 27. For example, the row of tabs 28 are equally spaced apart. The tabs 28 can be bent over the expansion material strip, for example, by hand or a handheld tool. In the illustrated embodiment, the tabs 28 are punched into the extension frame 20, and bending the tabs 28 forms corresponding through holes in the extension frame 20. When fastened by the tabs 28, the expansion material strips 27 are positioned adjacent to the holes so as not to cover said holes. For example, one or more expansion material strips 27 are positioned on the inner and / or outer periphery of the extension frame 20 adjacent to a row of such tabs 28. Thus, the tabs 28 may be folded inward and / or outward to clamp the expansion material strips 27 on either side. Alternatively, the extension frame 20 is positioned without the tabs 28, and instead, corresponding holes are formed positioned around the periphery of the extension frame 20. When the tabs 28 are bent to hold the expansion material strips 27, the through holes formed in the extension frame 20 may provide ventilation for cooling cables and / or pipes in the event of a fire on the other side of the partition.

[0027] In a first aspect of the invention, the extension frame 20 includes a plurality of extension frame modules 29 connectable to one another by connecting elements 30 to form the extension frame 20. In the illustrated embodiment, the extension frame modules 29 are connectable to one another by connecting elements 30 and locking elements 31, such as form-fit locks. Alternatively, the connecting elements 30 are directly connected to one another. In FIG. 4, four extension frame modules 29 are shown connected by connecting elements 30 and three locking elements 31, which cover the connecting elements 30 during use.

[0028] 6-8 and 12-13, each extension frame module 29 includes a first end, a second end, and an axially extending edge extending from the first end to the second end. Each extension frame module 29 includes three walls 32-34, with the first and second walls 32, 33 facing each other and connected via a third wall 34. The first and second walls 32, 33 extend perpendicularly from the third wall 34. The extension frame module 29 has, for example, a U-shaped profile. Thus, the extension frame module 29 includes two opposing axially extending free edges and two opposing axially extending edges connected to the third wall 34. In one embodiment, the extension frame modules 29 are identical.

[0029] The axially extending edges are provided with connection elements 30. For example, each connection element 30 is arranged to connect to a connection element 30 of an adjacent extension frame module 29, for example, by a locking element 31. In the illustrated embodiment, each connection element 30 includes a hook portion for connecting to a corresponding connection element 30 of an adjacent extension frame module 29 by the locking element 31. For example, the locking element 31 is a form-fit lock, such as a strip or clip that encapsulates the connection element 30 of the adjacent extension frame module 29.

[0030] With reference to FIG. 7, the axially extending free edge of each extension frame module 29 is provided with a first connection element 30a and the other axially extending edge is provided with a second connection element 30b. The first and second connection elements 30a, 30b are formed as hook portions extending away from each other. In the illustrated embodiment, the first connection element 30a is a continuous hook portion formed by bending the axially extending free edge of the extension frame module 29, and the second connection element 30b is formed by intermittently cutting and bending a tab along the axially extending edge connected to the third wall 34. Thus, two extension frame modules 29 may be arranged with a first wall 32 and a second wall 33 facing each other and connected by the first connection element 30a and the locking element 31. In addition, another extension frame module 29 may be arranged so that its third wall 34 faces the third wall 34 of an adjacent extension frame module 29, and the extension frame modules are connected to each other by the second connection element 30b and the locking element 31, as shown in Figures 4 and 5.

[0031] A fastening element 35 is provided at a first end of each extension frame module 29. In the embodiment of Figures 6-8, the fastening elements 5 are arranged to be fastened to the mounting frame 19, and the extension frame 20 can be attached to the mounting frame 19. In the embodiment shown, the fastening elements 35 are tabs having through holes for receiving screws, so that the extension frame modules 29 can be fastened to the mounting frame 19 by screws.

[0032] Alternatively, the fastening elements 35 are form-fitting fastening elements such as hooks, headed pins or similar elements having a shape that fits into a corresponding recess for fastening.

[0033] Each extension frame module 29 is provided with holes and one or more strips of expansion material 27 that are arranged to align with a corresponding row of holes and strips of expansion material 27 in an adjacent extension frame module 29. Thus, when two extension frame modules 29 are combined to form an opening for cables and / or pipes, the strips of expansion material 27 of two adjacent extension frame modules 29 together extend along the inner periphery of the extension frame 20, and optionally also around its outer periphery.

[0034] In the embodiment of Figures 4-8 and 12-15, the extension frame 20 is provided with a plurality of individual displacement elements 36. The displacement elements 36 are displaceable from a first position extending radially inwardly to a second position extending at least partially in a direction along the extension frame 20. The displacement elements 36 may be arranged to provide a screen to prevent unwanted access to the interior of the penetration device 10 from one end. Thus, when in the first position, the displacement elements 36 may at least partially block an axially extending opening in the extension frame.

[0035] In the illustrated embodiment, the displacement element 36 is disposed at one end of the extension frame 20 opposite the mounting frame 19. Thus, a first end of the extension frame 20 is connected to the mounting frame 19, and a second end of the extension frame 20 is provided with the displacement element 36. Alternatively, the first end of the extension frame 20 is directly connected to the partition 12, and a second end of the extension frame 20 is provided with the displacement element 36. Each displacement element 36 is elongated and includes a first end and a second end. The first end of the displacement element 36 is connected to the extension frame 20 at a connection, and the displacement element 36 is displaceable from a first position to a second position about the connection. Thus, the displacement element 36 can bend or bend from the first position to the second position at the connection. For example, the displacement element 36 is formed of a relatively thin sheet metal, and therefore can be bent by hand from the first position to the second position. Thus, the displacement element 36 may be formed as a bendable elongated finger connected to one end of the extension frame 20. In one embodiment, the walls 32-34 and the displacement element 36 are formed of sheet metal. At least one wall of the extension frame 20 has the displacement element 36 disposed thereon, or at least two walls thereof, for example two opposing walls, have the displacement element 36 disposed thereon.

[0036] The second end of the displacement element 36 may be a free end.

[0037] Alternatively, the second end of each displacement element 36 may contact or be connected to an opposing wall of the extension frame 20 and to an opposing displacement element 36 extending from the opposing wall of the extension frame 36, the second end being connected to the opposing wall or displacement element 36 by a breakable notch that can be broken by hand.

[0038] In the illustrated embodiment, the displacement elements 36 are disposed on the third wall 34 of each extension frame module 29. Alternatively, the displacement elements 36 are disposed on opposing walls of the non-modular extension frame 20.

[0039] Alternatively, the displacement elements 36 are arranged on the opposing first and second walls 32, 33 of the extension frame module 29. For example, the displacement elements 36 extend perpendicular to the extension frame 20 in the first position, e.g., perpendicular to the third wall 34 as shown. The displacement elements 36 may therefore extend in a plane perpendicular to the axial direction and perpendicular to the first, second and third walls 32-34. In the illustrated embodiment, the displacement elements 36 are distributed in a spaced apart manner in the plane such that gaps are formed between the displacement elements 36 extending from the same wall. The gaps may, for example, substantially correspond to the width of the displacement elements 36.

[0040] When the cables and / or pipes are passed through or when the penetration device 10 is positioned around the cables and / or pipes, the appropriate displacement elements 36 are displaced from a first position to a second position to allow the cables and / or pipes to pass. Thus, the one or more displacement elements 36 in the desired position are displaced so as not to impede the passage of the cables and / or pipes through the penetration device 10.

[0041] 9-11, a mounting frame 19 will be described according to various embodiments. In FIG. 9, a first end module 23 and a second end module 24 are shown, and the first end module 23 may be directly connected to the second end module 24. In FIG. 10, two intermediate modules 25 are disposed between the first end module 23 and the second end module 24, and the first end module 23 may be connected to an adjacent intermediate module 25, which may in turn be connected to the second end module 24. For example, the penetration device 10 may include one, two, three or any suitable number of intermediate modules 24.

[0042] In the embodiment of Figures 9-11, the first and second end modules 23, 24 and the intermediate module 25 of the mounting frame 19 are provided with optional removable covers 21 that cover their openings before use of the penetration device 10. For example, the covers 21 are an integrated part of the modules 23-25 ​​and are connected to the rest of the modules 23-25. For example, the mounting frame modules 23-25 ​​are made of a plastic material such as a flame-retardant polyamide. The covers 21 may be connected to the first and second end modules 23, 24 and the intermediate module 25 by breakable peripheral cutouts 37. For example, each cover 21 is generally rectangular and is connected to the end module 23, 24 or the intermediate module 25 by three peripheral cutouts 37. Thus, when the modules 23-25 ​​are separated, the cover 21 is connected to the modules 23-25 ​​by the three peripheral cutouts 37, leaving a free edge of each cover 21 facing or in contact with the cover 21 of the adjacent module 23-25 ​​(the free edges of the cover are more clearly visible in Figures 9 and 10). Also, two breakable diagonal cutouts 38 are formed in each cover 21 between the periphery of the cover 21 and its free edge. For example, each of the diagonal cutouts 38 extends from one of the breakable peripheral cutouts 37 to the free edge. In the illustrated embodiment, one diagonal cutout 38 extends from each corner of the peripheral cutouts 37 to the center of the free edge. Optionally, the cover 21 is also arranged with a cross cutout 39 extending between the center of the free edge and the center of the peripheral cutout 37 facing the free edge.

[0043] In FIG. 11, a form-fit locking device 26 for connecting modules 23-25 ​​of a mounting frame 19 is shown according to one embodiment. FIG. 11 shows a first end module 23 and a second end module 24 connected to one intermediate module 25 by four form-fit locking devices 26. However, as mentioned above, the number of intermediate modules 25 can be any number. The form-fit locking device 26 is arranged as a profiled piece, e.g. made of metal or plastic, which is inserted into the respective slots of the modules 23-25, one part of the form-fit locking device 26 being inserted into the slot of one of the modules 23-25 ​​and the other part being inserted into the slot of the adjacent module 23-25. For example, the modules 23-25 ​​are formed with corresponding slots which align to form a combined slot, e.g. the combined slot has a shape corresponding to the form-fit locking device 26 for receiving the form-fit locking device 26. In the illustrated embodiment, the form-fit locking device 26 includes opposing transverse sections connected via connectors that connect the transverse sections and are positioned to prevent displacement of the modules 23-25 ​​away from one another. For example, a slot may extend axially and the form-fit locking device 26 may be inserted axially into the slot to prevent inadvertent displacement of the modules 23-25 ​​relative to one another in a plane perpendicular to the axial direction.

[0044] As shown in Figures 6, 9 and 10, the mounting frame modules 23-25 ​​may be arranged with recesses 40 and protrusions 41 forming overlaps to prevent the modules 23-25 ​​from being inadvertently displaced axially relative to one another. The modules 23-25 ​​may also include at least one protrusion 42, for example arranged as a pin, and at least one corresponding hole 43 for receiving the protrusion 42 of an adjacent module 23-25. For example, the protrusion 42 and the hole 43 extend in a direction perpendicular to the axial direction to prevent the modules 23-25 ​​from being inadvertently displaced axially relative to one another.

[0045] Returning to FIG. 6, the penetration device 10 is provided with an optional insulating element 44. The insulating element 44 is arranged, for example, to improve fire protection and / or thermal insulation performance. In this embodiment, the insulating element 44 is arranged as a block of insulating material, such as mineral or ceramic. In the illustrated embodiment, the insulating element 44 is attached to the mounting frame 19 to insulate the opening formed by the mounting frame 19 for the penetration of cables and / or pipes. For example, the insulating element 44 is attached to the cover 21. The cover 21 of each mounting frame module 23-25 ​​is thus provided with an insulating element 44, and the mounting frame modules 23-25 ​​radially partially surround the outer periphery of the insulating element 44. When the mounting frame modules 23-25 ​​are combined to form the mounting frame 19, the insulating elements 44 of adjacent mounting frame modules 23-25 ​​are combined and surrounded by the mounting frame 19. The insulating element 44 may correspond to the shape and size of the cover 21. The insulating element 44 may be removable from the cover 21, by first removing the insulating element 44 and then removing the cover 21, for example by breaking the breakable cutouts 37, 38, 39, as described above. In the illustrated embodiment, the insulating element 44 is removably attached to the cover 21 by one or more screws 45 or other mechanical fastening means. Alternatively, the insulating element 44 may be removable together with the cover 21, for example via breakable cutouts in the insulating element 44 that correspond to the peripheral cutouts 37 and / or the diagonal cutouts 38 and the cross cutouts 39 of the cover 21. The screws 45 are placed from the same side as the extension frame 20, and the screw heads of the screws 45 may be accessed through the extension frame 20, for example after bending the displacement element 36 out of the way.

[0046] Alternatively, the insulating element 44 is removed before mounting the extension frame 20. Referring also to FIG. 11, the cover 21 is provided with screw sleeves 46 for receiving screws 45 for fastening the insulating element 44. The screw sleeves 46 protrude, for example axially, from one side of the cover 21 and may be an integral part of the cover 21. The screw sleeves 46 are formed with, for example, internal threads for mating with the threads of the screws 45. Thus, a penetration device 10 for passing one or more cables 11 and / or pipes through an opening in a partition 12 is disclosed, the penetration device 10 including a mounting frame 19 having a removable insulating element 44. The insulating element 44 may have a stand-alone feature of the mounting frame 19, modular or non-modular. Optionally, the mounting frame 19 includes mounting frame modules 23-25 ​​as described above, and the insulating element 44 is attached to the cover 21 of each of the mounting frame modules 23-25 ​​of the mounting frame 19, such as by means of screws 45 mating with the screw sleeves 46. The penetration device 10 from which the insulating element 44 is removable may optionally include an extension frame 20 that includes the extension frame module 29 described above.

The fastening element 35' is formed in a flange shape and has a through hole for receiving a fastener such as a screw or other type of conventional fastening means (not shown). Thus, the extension frame module 29 can be fastened to the partition 12 by a screw or the like. Optionally, the extension frame module 29 is fastened to the partition 12. For example, referring to FIG. 1, the extension frame 20 and the mounting frame 19 are arranged on both sides of the partition 12.

[0048] 13, an extension frame module 29 is attached to the partition 12. Similarly, the entire extension frame 20, including multiple extension frame modules 29, can be attached to the partition 12. The mounting frame 19 is attached to the partition 12 from the opposite side of the partition 12. In FIG. 13, the second end module 24 is shown moving away from the partition 12. The mounting frame 19 is placed in an opening in the partition 12, e.g., after it is assembled.

[0049] FIG. 14 shows two extension frame modules 29 connected by said connecting element 30 and optionally also by said locking element 31. Fastening elements 35' are provided at least on the two opposite first and second walls 32, 33 and also on the third wall 34 of the extension frame module 29 used as an end module. The fastening elements 35' can be provided, for example, along the periphery of the connected extension frame modules 29 and fastened to the other side of the partition 12 opposite to the side of the partition 12 to which the mounting frame 19 is attached. FIG. 15 shows almost the same features as shown in FIG. 14, but includes several interconnected extension frame modules 29, where the intermediate extension frame module 29 is provided only with fastening elements 35' on the two opposite first and second walls 32, 33 and the extension frame module 29 being an end module is also provided with fastening elements 35' on the third wall 34.
