Abstract
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. This type of transit device comprises an elongate frame having a central axially extending opening. Such transit devices are used for passing cables and / or pipes through a wall or other types of partitions. This type of transit device may comprise a mounting frame having a central axially extending opening, which mounting frame can be connected to a partition. Background Art
[0002] Different types of transit devices are used for passing cables and / or pipes through a wall or other partitions. Generally, for a sealed transit, some kind of seal is arranged inside a mounting frame placed in an opening of the partition. One example of a seal is a plurality of compressible modules that receive cables or pipes. Such compressible modules are normally received in one or more rows together with a compression part in the mounting frame. By means of the compression part, the compressible modules are compressed in one direction such that the compressible modules seal inwardly around the cables and / or pipes and seal outwardly against the inside of the mounting frame.
[0003] Transit devices for cables and pipes are used in various environments such as cabinets, technical shelters, junction boxes, and machinery. They are used in different industrial environments including automotive, telecommunications, power generation and distribution, as well as shipbuilding and offshore industries. They provide a seal against fluids, gases, fire, rodents, termites, dust, moisture, etc., and may receive cables for electricity, telecommunications, computers, etc., or pipes for various gases or liquids such as water, compressed air, hydraulic fluid, cooking gas, etc.
[0004] Various types of penetration devices require fire resistance, and it is common practice to place some kind of fire-resistant material inside them. In this field, the use of intumescent material as a fire-resistant material is well known. Intumescent material is a material that expands when exposed to excessive heat, such as during a fire. Intumescent material may also function as an insulating material for cables in the event of a fire.
[0005] In the prior art, a penetration device includes an extension frame having axially extending penetration openings for cables and / or pipes. One or more inflatable material strips and multiple holes penetrating the wall of the extension frame are provided in the extension frame. Holes in the extension frame located on the fire side improve the reaction time of the inflatable material. This allows the inflatable material to react as quickly as possible and begin to function as an insulator around the cables. Holes in the extension frame on the non-fire side ventilate the frame and cool the cables. Therefore, the purpose of the holes differs depending on which side of the wall the extension frame is located on.
[0006] Conventional penetration devices have the problem of not being usable for different types of cables and / or pipes in different applications. Therefore, conventional penetration devices have limitations in their use and are not efficient to install depending on the current application. [Overview of the project]
[0007] Based on the above, the present invention aims to provide a penetration device that can be efficiently installed. According to a first aspect of the present invention, the aim is to provide a flexible penetration device that operates in a variety of applications. According to a second aspect of the present invention, the aim is to provide a penetration device having improved fire protection.
[0008] According to a first aspect, the present invention relates to a through-device for passing one or more cables and / or pipes through an opening in a partition, wherein the through-device includes an extension frame that is connectable to a mounting frame and / or the partition and has an axially extending through-opening for cables and / or pipes, the extension frame includes a plurality of extension frame modules having a first end, a second end, and an axially extending edge portion extending between the first end and the second end, the axially extending edge portion being provided with a connecting element, the extension frame modules being connectable to each other by the connecting element to form the extension frame, and the first end of the extension frame module is provided with a fastening element for fastening to the mounting frame and / or partition. Thus, a versatile module through-device is realized that can be adapted to various applications in an efficient, reliable, and cost-effective manner. Furthermore, the structure of the through-device is lightweight and easy to install. The through-device may include the mounting frame, and the extension frame is connected to the mounting frame and / or the partition and extends axially from or away from the mounting frame.
[0009] Each of the axially extending edges may be provided with a connecting element. For example, each extension frame module has three axially extending walls and four axially extending edges, two of which are free edge portions. Therefore, 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, adjacent extension frames can be connected to each other. Furthermore, the extension frame modules may be identical, which simplifies manufacturing, reduces costs, and simplifies installation.
[0010] The connecting element may include a hook portion for connecting to the hook portion of an adjacent extension frame module by a locking element such as a form-fit lock in the form of a strip or clip that encloses one or more connecting elements of two adjacent extension frame modules. Therefore, the connecting element can be manufactured simply and inexpensively by bending the hook portion at the free edge and punching out and bending the hook portion at the other edge. For this reason, the extension frame modules can be arranged on a sheet metal or other sheet metal by bending and punching them out.
[0011] Each extension frame module may be provided with one or more expansion material strips aligned with the corresponding strips of adjacent extension frame modules. Thus, flame-retardant transport may be achieved by the penetration device in an efficient manner. By arranging the expansion material strips adjacent to at least one row of holes that are at least partially unobstructed, ventilation for cooling on the non-fire side can be achieved while enabling a rapid response to heat on the fire side of the partition. Holes in the extension frame located on the fire side improve the reaction time of the expansion material. This allows the expansion material to react quickly and begin to function as an insulator around the cables. 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 the purpose of the holes differs depending on which side of the wall the extension frame is located on.
[0012] The mounting frame may include multiple mounting frame modules that can be connected to each other to form the mounting frame. Therefore, both the extension frame and the mounting frame may be modular for assembling a suitable through-frame.
[0013] Each mounting frame module may be provided with a removable cover that can be removed before cables and / or pipes are installed. The cover can prevent debris and liquids from entering the penetration device before cables and / or pipes are installed. The cover may be provided for fire protection. For example, the cover may be made of a fire-resistant material such as a plastic material containing a flame retardant, or it may contain a fiber-reinforced material 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 breakable oblique and / or cross notches that extend from the breakable peripheral notch to the free edge of the cover.
[0014] The extension frame is provided with a plurality of individual displacement elements that are displaceable from a first position to a second position, where, in the first position, the displacement elements extend radially inward, and where, in the second position, the displacement elements extend at least partially in a direction along the extension frame. The displacement elements act as barriers to prevent unwanted access to the extension frame, prevent unwanted material from entering the extension frame, and improve fire protection of the penetration device. One or more displacement elements can be displaced to facilitate the installation of cables and / or pipes, and can be bent, for example, by hand. Therefore, the displacement elements may be formed from sheet metal and, together with the extension frame module, may be formed, for example, from a single sheet of sheet metal by bending and punching.
[0015] According to a second aspect, the present 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, having an axially extending penetration opening for cables and / or pipes, wherein the extension frame is provided with a plurality of individual displacement elements that are displaceable from a first position to a second position, wherein 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 act as barriers to prevent unwanted access to the extension frame and to prevent unwanted material from entering the extension frame. In the event of a fire, the pipe or cable conducts heat through the partition, and flammable material in contact with or near the cable or pipe adjacent to the partition can ignite due to the heat. The displacement elements reduce the risk of flammable material entering the extension frame. One or more displacement elements can be displaced to facilitate the installation of cables and / or pipes, for example, by bending by hand. The displacement element may be formed from sheet metal, and together with the extension frame, may be formed, for example, from a single sheet of sheet metal by bending and punching. The through-device may include a mounting frame, the extension frame being connected to the mounting frame and / or partitions, and extending axially from or away from the mounting frame.
[0016] The first end of the extension frame may be connected to a mounting frame and / or partition, and a displacement element may be provided at the second end of the extension frame. Thus, the displacement element may at least partially block the axially extending opening at the second end of the extension frame at the first position.
[0017] The penetration device according to the second embodiment can be combined with the embodiment according to the first embodiment described above and will be 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 reading the following detailed description. [Brief explanation of the drawing]

[0020] Referring 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 schematically shown. The penetration device 10 is arranged for passing one or more cables 11 and / or pipes through the partition 12 in the form of a wall, floor, roof or ceiling. The partition 12 is shown by broken lines in FIG. 1. For example, the penetration device 10 is arranged to be attached to a partition 12 including studs provided with panels such as building boards made of gypsum or wood. For example, the penetration device 10 is arranged for passing cables 11 such as cables for electricity, communication, computers, etc., or pipes for various gases or liquids such as water, compressed air, hydraulic fluid, cooking gas, and other liquids or gases. Cables and / or pipes are guided axially through the penetration device 10.
[0021] The through-device 10 in Figure 1 is arranged to receive one or more sealing modules 13, a compression section 14, and optional stayplates 15. The sealing modules 13 may be arranged in different sizes, and multiple different sealing modules 13 may be arranged in different configurations, as also shown with reference to Figure 2. For example, the sealing modules 13, compression section 14, and stayplates 15 are conventional, where applicable. For example, the sealing module 13 is elastic and includes two opposing sealing halves 16, each half module 16 including multiple release sheets 17 arranged in a semi-cylindrical groove 18, as shown in Figure 3. Optionally, an appropriate number of release sheets 17 are removed to fit the sealing module 16 to the diameter of a cable or pipe, the cable 11 or pipe is placed inside the half module 16, and the sealing module 13 is formed by overlapping two half modules 16. For example, the compression section 14 is a conventional wedge.
[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 positioned to receive one or more compressible sealing modules 13 into a central axially extending opening through which one or more cables and / or pipes are placed. In Figure 4, the 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 positioned to be sealed with the sealing modules 13, one or more compression sections 14, and one or more optional stay plates 15. For example, the mounting frame 19 is formed of a plastic material such as fiber-reinforced plastic. For example, the mounting frame 19 is formed of a polyamide such as glass fiber-reinforced polyamide. Therefore, the mounting frame 19 is lightweight and suitable for mounting to panel walls such as walls containing 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 through-device 10 to the partition 12 by screws or other conventional fastening means (not shown). For example, the flange 22 is provided with holes for receiving screws. The extension frame 20 may extend away from the mounting frame 19 and the partition. Alternatively, as shown in Figure 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 comprising first and second end modules 23, 24 and one or more intermediate modules 25 positioned between the end modules 23, 24. For example, the first and second end modules 23, 24 each include three wall sections, two of which face each other and are connected to each other at one end via the other wall section. For example, the first and second end modules 23, 24 are identical. The intermediate module 25 includes opposing wall sections connected to each other via a centrally located wall section. The first and second end modules 23, 24 may be connected to each other or to the intermediate module 25 by a shape-fitting locking device 26, which will be described in more detail below. In Figure 4, the end modules 23, 24 and the intermediate module 25 form two openings for cables and / or pipes, which are positioned parallel to each other in the figure and covered by a removable cover 21.
[0025] The extension frame 20 is connected to the mounting frame 19 and extends axially from the mounting frame 19. The extension frame 20 and the mounting frame 19 form an axially extending opening through the mounting frame 19 and the extension frame 20, and one or more cables and / or pipes may be placed in the opening through the extension frame 20 and the mounting frame 19, for example, after removing any cover 21.
[0026] At least one expansion material strip 27 is positioned on the inner and / or outer circumference of the extension frame 20. The expansion material strip 27 is attached to the surface of the extension frame 20 by, for example, an adhesive. However, such adhesives have been found to be unreliable, for example, at high temperatures. In the illustrated embodiment, the extension frame 20 is provided with bendable tabs 28 that can be bent over the expansion material strip 27 to clamp it 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 perimeter of the extension frame 20. In the illustrated embodiment, the tabs 28 are arranged in a row around the extension frame 20 adjacent to the expansion material strip 27. For example, the row of tabs 28 is arranged at equal intervals. The tabs 28 can be bent over the expansion material strip by, for example, by hand or a handheld tool. In the illustrated embodiment, the tabs 28 are punched into the extension frame 20, and the bending of the tabs 28 forms corresponding through holes in the extension frame 20. When fastened by tabs 28, the expansion material strips 27 are positioned adjacent to the holes, but not covering them. For example, one or more expansion material strips 27 are positioned on the inner and / or outer circumference of an extension frame 20 adjacent to such a row of tabs 28. Thus, the tabs 28 may be bent inward and / or outward to clamp the expansion material strips 27 on either side. Alternatively, the extension frame 20 may be positioned without tabs 28, and instead, corresponding holes are formed around the extension frame 20. If tabs 28 are bent to hold the expansion material strips 27, the through-holes formed within 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 present invention, the extension frame 20 is connectable to one another by connecting elements 30 and includes a plurality of extension frame modules 29 that 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 shape-fitting locks. Alternatively, the connecting elements 30 are directly connected to one another. Figure 4 shows four extension frame modules 29 connected by connecting elements 30 and three locking elements 31, the locking elements 31 covering the connecting elements 30 during use.
[0028] Referring also to Figures 6-8 and 12-13, each extension frame module 29 includes a first end, a second end, and an axially extended 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 contour. Thus, the extension frame module 29 includes two opposing axially extended free edges and two opposing axially extended edges connected to the third wall 34. In one embodiment, the extension frame module 29 is identical.
[0029] A connecting element 30 is provided on the axially extending edge. For example, each connecting element 30 is arranged to connect to a connecting element 30 of an adjacent extension frame module 29 by, for example, a locking element 31. In the illustrated embodiment, each connecting element 30 includes a hook portion for connecting to the corresponding connecting element 30 of an adjacent extension frame module 29 by a locking element 31. For example, the locking element 31 is a shape-fitting lock such as a strip or clip that encloses the connecting element 30 of the adjacent extension frame module 29.
[0030] Referring to Figure 7, a first connecting element 30a is provided on the axially extending free edge of each extension frame module 29, and a second connecting element 30b is provided on the other axially extending edge. The first and second connecting elements 30a and 30b are formed as hook portions that extend away from each other. In the illustrated embodiment, the first connecting element 30a is a continuous hook portion formed by bending the axially extending free edge of the extension frame module 29, and the second connecting element 30b is formed by intermittently cutting and bending tabs 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 connecting element 30a and the locking element 31. Furthermore, other extension frame modules 29 may be arranged such that their 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 second connecting elements 30b and locking elements 31, as shown in Figures 4 and 5.
[0031] A fastening element 35 is provided at the first end of each extension frame module 29. In the embodiments shown in Figures 6-8, the fastening element 5 is positioned to fasten to the mounting frame 19, and the extension frame 20 is attachable to the mounting frame 19. In the illustrated embodiments, since the fastening element 35 is a tab with a through hole for receiving a screw, the extension frame module 29 can be fastened to the mounting frame 19 by screw.
[0032] Alternatively, the fastening element 35 is a shaped fitting fastening element such as a hook or a pin with a head, or a similar element 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 expansion material strips 27, which are arranged to align with the corresponding rows of holes and expansion material strips 27 of adjacent extension frame modules 29. Thus, when two extension frame modules 29 are combined to form an opening for cables and / or pipes, the expansion material strips 27 of the two adjacent extension frame modules 29 extend together along the inner circumference of the extension frame 20, and optionally along its outer circumference as well.
[0034] In the embodiments shown in 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 inward to a second position extending at least partially in the direction along the extension frame 20. The displacement elements 36 may be positioned to provide a screen to prevent unwanted access to the interior of the through-device 10 from one end. Thus, when in the first position, the displacement elements 36 may at least partially block the axially extending opening of the extension frame.
[0035] In the illustrated embodiment, the displacement element 36 is positioned at one end of the extension frame 20 opposite to the mounting frame 19. Thus, the first end of the extension frame 20 is connected to the mounting frame 19, and the displacement element 36 is provided at the second end of the extension frame 20. Alternatively, the first end of the extension frame 20 is directly connected to the partition 12, and the displacement element 36 is provided at the second end of the extension frame 20. 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 the connection point, and the displacement element 36 is displaceable from a first position to a second position around the connection point. Thus, the displacement element 36 can bend or fold from the first position to the second position at the connection point. For example, since the displacement element 36 is made of relatively thin sheet metal, it 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-like object connected to one end of the extension frame 20. In one embodiment, the walls 32-34 and the displacement elements 36 are formed of sheet metal. Displacement elements 36 are placed on at least one wall of the extension frame 20, or on at least two walls, for example, two opposing walls.
[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 connect to an opposing wall of the extension frame 20, or to an opposing displacement element 36 extending from the opposing wall of the extension frame 36, and the second end may be 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 element 36 is positioned on the third wall 34 of each extension frame module 29. Alternatively, the displacement element 36 is positioned on the opposing wall of a non-modular extension frame 20.
[0039] Alternatively, the displacement elements 36 are positioned on opposing first and second wall portions 32 and 33 of the extension frame module 29. For example, at the first position, the displacement elements 36 extend perpendicularly to the extension frame 20, and, for example, perpendicularly to the third wall 34 as shown in the figure. Thus, the displacement elements 36 may extend in a plane perpendicular to the axial direction and perpendicularly to the first, second, and third walls 32-34. In the illustrated embodiment, the displacement elements 36 are distributed in the plane with spacing between them so that gaps are formed between displacement elements 36 extending from the same wall. These gaps substantially correspond to, for example, the width of the displacement elements 36.
[0040] When a cable and / or pipe is passed through the through-device 10, or when the through-device 10 is positioned around a cable and / or pipe, the appropriate displacement element 36 is displaced from a first position to a second position to allow the cable and / or pipe to pass through. Thus, one or more displacement elements 36 in the desired position are displaced so as not to obstruct the passage of the cable and / or pipe passing through the through-device 10.
[0041] Referring to Figures 9 to 11, the mounting frame 19 will be described according to various embodiments. In Figure 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 Figure 10, two intermediate modules 25 are arranged between the first end module 23 and the second end module 24, and the first end module 23 is connected to an adjacent intermediate module 25, which is then connected to another adjacent intermediate module 25, which is then connected to the second end module 24. For example, the through-mount device 10 may include one, two, three, or an appropriate number of intermediate modules 24.
[0042] In the embodiments shown in 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 through-device 10. For example, the cover 21 is an integrated part of modules 23-25 and is connected to the rest of modules 23-25. For example, the mounting frame modules 23-25 are formed of a plastic material such as flame-retardant polyamide. The cover 21 may be connected to the first and second end modules 23, 24 and the intermediate module 25 by breakable peripheral notches 37. For example, each cover 21 is substantially rectangular and is connected to the end modules 23, 24 or the intermediate module 25 by three peripheral notches 37. Therefore, when modules 23-25 are separated, the cover 21 is connected to modules 23-25 by three peripheral notches 37, leaving a free edge of each cover 21 that faces or contacts the cover 21 of the adjacent modules 23-25 (the free edges of the covers are more clearly visible in Figures 9 and 10). In addition, each cover 21 has two breakable oblique notches 38 formed between the periphery of the cover 21 and its free edge. For example, each oblique notch 38 extends from one of the breakable peripheral notches 37 to the free edge. In the illustrated embodiment, one oblique notch 38 extends from each corner of the peripheral notch 37 to the center of the free edge. Optionally, the cover 21 also has a cross notch 39 extending between the center of the free edge and the center of the peripheral notch 37 facing the free edge.
[0043] Figure 11 shows a shape-fitting locking device 26 for connecting modules 23-25 of a mounting frame 19 according to one embodiment. Figure 11 shows a first end module 23 and a second end module 24 connected to an intermediate module 25 by four shape-fitting locking devices 26. However, as mentioned above, the number of intermediate modules 25 is arbitrary. The shape-fitting locking devices 26 are arranged as profiled pieces, such as metal or plastic, which are inserted into the respective slots of modules 23-25, with a portion of the shape-fitting locking device 26 inserted into one slot of module 23-25 and the remainder inserted into the slots of adjacent modules 23-25. For example, modules 23-25 have corresponding slots formed therein, which align to form a combined slot, and the combined slot has a shape corresponding to the shape-fitting locking device 26 in order to receive the shape-fitting locking device 26. In the illustrated embodiment, the shape-fitting locking device 26 includes opposing transverses connected via a connector, the connector connecting the transverses and positioned to prevent modules 23-25 from being displaced apart from each other. For example, the slot extends axially, and the shape-fitting locking device 26 is inserted axially into the slot to prevent modules 23-25 from unintentionally shifting in a plane perpendicular to each other axially.
[0044] As shown in Figures 6, 9, and 10, the mounting frame modules 23-25 may be provided with recesses 40 and protrusions 41 that form overlapping portions to prevent the modules 23-25 from unintentionally shifting axially relative to each other. Furthermore, modules 23-25 may include, for example, at least one projection 42 arranged as a pin, and at least one corresponding hole 43 that receives the projection 42 of an adjacent module 23-25. For example, the projections 42 and holes 43 extend in a direction perpendicular to the axial direction to prevent the modules 23-25 from unintentionally shifting axially relative to each other.
[0045] Returning to Figure 6, the penetration device 10 is provided with an optional insulating element 44. The insulating element 44 is provided, for example, to improve fire resistance and / or thermal insulation performance. In this embodiment, the insulating element 44 is provided 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. Thus, the cover 21 of each mounting frame module 23-25 is provided with an insulating element 44, and the mounting frame modules 23-25 partially surround the outer circumference of the insulating element 44 in the radial direction. 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 is removable from the cover 21, and the cover 21 can be removed by first removing the insulating element 44 and then, as described above, for example, by breaking the breakable notches 37, 38, 39. In the illustrated embodiment, the insulating element 44 is detachably attached to the cover 21 by one or more screws 45 or other mechanical fastening means. Alternatively, the insulating element 44 is removable together with the cover 21, for example, through breakable notches in the insulating element 44 corresponding to the peripheral notches 37 and / or oblique notches 38 and cross notches 39 of the cover 21. The screws 45 are located on the same side as the extension frame 20, and the screw heads of the screws 45 may be accessed through the extension frame 20 after bending, for example, the displacement element 36 so as not to interfere.
[0046] Alternatively, the insulating element 44 is removed before installing the extension frame 20. See also Figure 11, the cover 21 is provided with screw sleeves 46 that receive 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 have, for example, female threads that screw into the threads of the screws 45. Thus, a pass-through device 10 is disclosed for passing one or more cables 11 and / or pipes through the opening of the partition 12, and the pass-through device 10 includes a mounting frame 19 having removable insulating elements 44. The insulating elements 44 may have independent features of a modular or non-modular mounting frame 19. Optionally, the mounting frame 19 includes mounting frame modules 23-25 as described above, and the insulating elements 44 are attached to the respective covers 21 of the mounting frame modules 23-25 of the mounting frame 19 by screws 45 that engage with the screw sleeves 46. The removable through-device 10 for the insulating element 44 may optionally include an extension frame 20 including the extension frame module 29.
[0047] Figure 12 shows an extension frame module 29 according to one embodiment, which has a structure similar to that illustrated and described in Figure 7, but differs in that the first end of the extension frame module 29 is provided with a fastening element 35' for direct fastening to the partition 12 (see Figure 13). The fastening element 35' is formed in a flange shape and has a through hole for receiving fasteners such as screws or other types of conventional fastening means (not shown). Thus, the extension frame module 29 can be fastened to the partition 12 with screws or the like. Optionally, the extension frame module 29 is fastened to the partition 12. For example, referring to Figure 1, the extension frame 20 and the mounting frame 19 are arranged on both sides of the partition 12.
[0048] Referring to Figure 13, the 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. Figure 13 shows that the second end module 24 is separated from the partition 12. The mounting frame 19 is positioned in the opening of the partition 12, for example, after assembly.
[0049] Figure 14 shows two extension frame modules 29 connected by the connecting element 30 and optionally by the locking element 31. The fastening element 35' is provided on at least two opposing first and second walls 32, 33 and optionally on the third wall 34 of an extension frame module 29 used as an end module. The fastening element 35' can be provided, for example, along the perimeter of the connected extension frame modules 29 and fastened to the other side of the partition 12 opposite to one side to which the mounting frame 19 is attached. Figure 15 shows substantially the same features as shown in Figure 14, but includes a plurality of interconnected extension frame modules 29, wherein the intermediate extension frame modules 29 are provided only on two opposing first walls 32 and second walls 33, and the extension frame modules 29 that are end modules are also provided with fastening elements 35' on the third wall 34.
