Description

[0001] The invention relates to a drainage channel with a connecting plate for connecting two drainage channels, and to a channel system with at least two such drainage channels.

[0002] Drainage channels are used to drain terraces, facades, flat roofs, and similar areas. They are installed as drainage systems in the ground to be drained. This allows surface water to flow from above into the drainage channels via grates. These types of drainage channels can also be called facade drainage channels.

[0003] Typically, these drainage channels are installed on-site in the required length by connecting them end-to-end. The installation and connection of the drainage channels is labor-intensive and cumbersome.

[0004] JP S59 233048 A relates to a reinforced concrete channel that can be used as a drainage channel, with a connecting plate that serves to connect the outer surface of an edge section of the channel to the outer surface of a horizontal support beam. Another drainage channel with a connecting plate is known from JP H02 269236.

[0005] US 2010 / 261402 A1, WO 2022 / 008588 A1, GB 27202 A concern connecting elements with webs, through-holes and fasteners.

[0006] It is therefore an object of the present invention to provide a drainage channel with a connecting plate for joining two drainage channels, which facilitates the on-site installation of drainage channels. A further object of the present invention is to provide a channel system with at least two such drainage channels.

[0007] This problem is solved according to the invention by a drainage channel with a connecting plate according to claim 1. With regard to the channel system, the problem is solved by the subject matter of claim 12.

[0008] The invention relates to a drainage channel, in particular a height-adjustable drainage channel, comprising at least one connecting plate and a channel base. The channel base has at least one counter-connecting element and at least one fixing element on at least one open end face of the drainage channel, wherein one of the two connecting elements of the connecting plate is connected to the counter-connecting element of the channel base and the other connecting element of the connecting plate can be fixed or is fixed by the fixing element of the channel base.

[0009] Specifically, the object of the invention is achieved by a drainage channel with a connecting plate for connecting two drainage channels. The connecting plate has two connecting sections which are connected to each other by two webs, with a through-opening formed between the webs. Each connecting section has a connecting element on its underside for connecting to a channel base of one of the drainage channels.

[0010] The invention is based on the idea of ​​providing a connecting plate for joining two drainage channels, comprising two, in particular plate-shaped, connecting sections which, in the assembled state, are each in contact with the channel base of one of the drainage channels. The connecting sections are linked to each other by two webs, thereby creating a connection between the two drainage channels in the assembled state. Such a design of a connecting plate has several advantages.

[0011] The assembly or connection of two drainage channels on-site using such a connecting plate is particularly easy. One of the two connecting sections can be pre-attached to the channel base of one drainage channel before installation, for example, during transport to the site. To connect the two drainage channels on-site, only the other connecting section needs to be attached to the channel base of the other drainage channel. This advantageously reduces the assembly effort on-site.

[0012] While one connecting section is attached to the channel base of one drainage channel before installation, for example during transport to the construction site, the other connecting section can be fixed to the same channel base. In other words, both connecting sections can rest against the channel base in the drainage channel before installation. This advantageously protects the connecting plate within the drainage channel before installation. Damage to the connecting plate, for example during loading and unloading or transport, can thus be avoided.

[0013] The connecting elements of the two connecting sections allow for easy attachment of the connecting section to the respective channel base. This eliminates the need for additional fasteners or fixings. The reduced number of components further simplifies assembly and reduces manufacturing effort.

[0014] The connecting plate has a relatively simple structure due to its two connecting sections, which are linked by two webs. The two webs advantageously increase the rigidity of the connecting plate against rotation of the connecting sections relative to each other in the plane of the plate. The opening between the webs saves on additional material.

[0015] The connecting plate is designed to join two drainage channels. Specifically, it is used to connect the channel bottoms of two drainage channels. The connecting plate can also be used to join other channel components, such as the side walls of two drainage channels.

[0016] Preferred embodiments of the invention are specified in the dependent claims.

[0017] It is advantageous if at least one of the two webs has a predetermined breaking point. This breaking point allows one of the two webs to be cut if necessary, thus reducing the rigidity of the connecting plate against rotation of the connecting sections relative to each other in the plane of the plate, such that the connecting sections can rotate relative to each other in the plane of the plate. In this way, the drainage channels can be mounted at an angle to each other. Depending on the application, both an aligned and an angled arrangement of two drainage channels connected by the connecting plate is therefore possible. This advantageously expands the range of applications for the connecting plate.

[0018] Preferably, at least one connecting element is adapted to rotatably connect the connecting section to the channel base of the drainage channel. This allows the connecting plate to rotate in the plane of the plate around the connecting element connected to the channel base. Thus, the connecting section, which is fixed to the channel base before installation, can be released from its fixing and manually rotated around the connected connecting section—without additional tools—and therefore removed from the drainage channel at an open end face. This further reduces the installation effort.

[0019] In a preferred embodiment of the invention, at least one of the two connecting elements has a projection that forms an undercut, at least partially radially circumferential, for snap-fit ​​connection with the channel bottom. Such a connecting element enables a particularly simple connection of the connecting section to the channel bottom. For connection, such a connecting element simply needs to be manually pressed into a corresponding mating connecting element on the channel bottom, without any additional tools, until the undercut engages.

[0020] In a further preferred embodiment of the invention, at least one of the two connecting sections has a support on its underside, which is arranged between the connecting element and the other connecting section. Such a support absorbs compressive forces that act, for example, on the upper side of the connecting plate during assembly. This advantageously relieves the respective connecting element of the connecting plate, thus preventing damage to the connecting element and / or the drainage channel.

[0021] To lift the connecting plate, for example from the channel base, it is advantageous if at least one of the two connecting sections has a chamfer on its underside, positioned on a side facing away from the other connecting section. If such a chamfered connecting section is attached to the channel base, this chamfer increases the potential lifting range when lifting the opposite connecting section. The chamfer also makes it easier to grip the chamfered connecting section from behind, for example, to lift it from its fixing on the channel base. Both of these features facilitate the installation of the drainage channels on-site.

[0022] Preferably, at least one of the two connecting sections has a round outer contour on a side facing away from the other connecting section. This allows the connecting section to be positioned particularly close to a side wall of the drainage channel, while ensuring that the connecting section can rotate about its connecting element. This can be advantageous, for example, if the drainage channels are to be connected or mounted at an angle to each other.

[0023] The through-opening preferably forms an elongated slot. Particularly preferably, the elongated slot extends longitudinally from one web to the other. Such a design of the through-opening saves additional material in the area between the connecting sections. The distance between the webs is increased, which advantageously enhances the stiffness of the connecting plate against rotation of the connecting sections relative to each other in the plane of the plate.

[0024] It is preferred if the connecting sections are mirror images of each other. This allows the connecting plate to be used effectively in different orientations, thus simplifying assembly. Furthermore, this reduces the complexity and therefore the manufacturing effort of the connecting plate.

[0025] For ease of manufacturing and reduced weight, the connecting plate is preferably made of a plastic.

[0026] In a preferred embodiment of the drainage channel, the fixing element of the channel base is positioned at a distance equal to or greater from a side wall of the drainage channel than the counter-connecting element. This design allows the counter-connecting element to be positioned as close as possible to the side wall, thus facilitating, for example, the angled installation of two drainage channels.

[0027] A further, subordinate aspect of the invention relates to a channel system with at least two drainage channels as described above. In this channel system, a connecting element of the connecting plate is connected to a corresponding connecting element of the channel base in such a way that the drainage channels are arranged in alignment or at an angle to one another.

[0028] The invention is explained in more detail below with reference to exemplary embodiments and the accompanying schematic drawings. These show: Fig. 1 a perspective view of the underside of a connecting plate according to an embodiment; Fig. 2 a perspective view of the top side of the connecting plate made of Fig. 1 Fig. 3 shows a perspective view of the underside of a connecting plate according to a further embodiment; Fig. 4 shows a perspective view of the top side of the connecting plate made of Fig. 3 Fig. 5 a perspective view of a drainage channel according to an embodiment without a connecting plate; Fig. 6 a perspective view of the drainage channel made of Fig. 5 with a connecting plate Fig. 1 ; Fig. 7 a cross-section through the drainage channel made of Fig. 6 ; Fig. 8 another perspective view of the drainage channel made of Fig. 6 Fig. 9 shows a perspective view of a gutter system according to an embodiment of the invention; and Fig. 10 shows a further perspective view of the gutter system made of Fig. 9 .

[0029] Fig. 1 Figure 1 shows a connecting plate 10 according to an exemplary embodiment. The connecting plate 10 has a substantially plate-shaped geometry with a plate thickness that is bounded by a bottom surface 16 and a top surface 17. In Fig. 1 The underside 16 of the connecting plate 10 is shown.

[0030] The connecting plate 10 has two connecting sections 11, which are connected to each other by two webs 12. The connecting sections 11 and the webs 12 each form sections or parts of the connecting plate 10. The connecting sections 11 and the webs 12 themselves therefore also have an essentially plate-like geometry with the plate thickness, the underside 16 and the top side 17 of the connecting plate.

[0031] A through-opening 14 is formed between the webs 12. The through-opening 14 is thus bounded by the two connecting sections 11 and the outer webs 12. The through-opening 14 separates the connecting sections 11 from each other, while the webs 12 connect the connecting sections 11 to one another.

[0032] Both webs 12 each have a predetermined breaking point 13. The predetermined breaking point 13 is designed to allow easy separation, for example, breaking or cutting, of the affected web 12. The predetermined breaking point 13 can be visible, for example, by a graphic marking or a notch, or invisible. The predetermined breaking point 13 can be located essentially in the center of the web 12, i.e., at an essentially equal distance from the two connecting sections 11. Other arrangements or designs of the predetermined breaking point are possible.

[0033] The connecting sections 11 each have a connecting element 18 on their underside 16. The connecting elements 18 are arranged substantially centrally with respect to the respective connecting section 11. The connecting elements 18 may be arranged differently.

[0034] Both connecting elements 18 are each adapted to rotatably connect the connecting section 11. In other words, the connecting elements 18 have a geometry that allows the connecting plate 10 to rotate around the connecting element 18.

[0035] Specifically, the connecting elements have a projection 19 that extends from the underside 16 of the connecting plate 10. To allow the connecting plate 10 to rotate about the projection 19, the projection 19 has a substantially circular cross-section. A central through-opening 25 is formed in the projection 19, extending to the underside 16 of the connecting plate 10. The projection 19 is thus essentially tubular. The projection 19 has two lateral recesses 24, which are arranged opposite each other and extend over the entire length of the projection 19. The recesses 24 therefore divide the tubular geometry of the projection 19 into two opposing, channel-shaped halves. The projection 19 can also have more than two such recesses 24.

[0036] The extensions 19 of both connecting elements 18 each form a radially circumferential undercut 20. The undercut 20 is thus formed radially circumferentially on the outside of the extension 19, with the recesses 24 of the extension 19 dividing the undercut 20 into two sections of essentially equal length. The undercut 20 thus extends radially outwards from the outside of the extension 19, specifically from the outside of the channel-shaped halves of the extension 19.

[0037] Both connecting sections 11 each have an abutment 21 on their underside 16, which is arranged between the connecting element 18 and the other connecting section 11. The abutment 21 forms a projection on the underside 16, the projection being lower in height relative to the underside 16 than the extension 19. The abutment 21 has a substantially semicircular plan and thus surrounds the connecting element 18 on one side. The abutment can also have other geometries, for example, a substantially straight plan. A bearing surface is formed on one side of the abutment 21 opposite the underside 16, which substantially follows the plan of the abutment 21.

[0038] Both connecting sections 11 have a chamfer 22 on their underside 16, located on a side facing away from the other connecting section 11. The chamfer 22 begins on the side facing away from the other connecting section 11 at a distance from the connector 18 and extends outwards in the direction of a connecting line of the two connectors 18 to an outer edge of the connecting section 11. Due to the chamfer 22, the plate thickness decreases essentially continuously.

[0039] Both connecting sections 11 each have a round outer contour 23 on one side facing away from the other connecting section 11. Specifically, the outer contour 23 is essentially semicircular. The connecting sections 11, together with the webs 12, have an outer contour that essentially corresponds to the geometry of an elongated hole. The webs 12 are essentially of the same length and arranged essentially parallel to each other.

[0040] The through-hole 14 forms an elongated hole 15. The elongated hole 15 extends with its longitudinal extent from one web 12 to the other web 12. In other words, the elongated hole 15 is oriented such that the longitudinal extent or longitudinal axis of the elongated hole is essentially perpendicular to the connecting line of the connecting means 18.

[0041] The connecting sections 11 are essentially mirror-symmetrical to each other. The connecting plate has two planes of symmetry. The first plane of symmetry intersects the longitudinal axis of the elongated hole 15 and is therefore located centrally between the two connecting sections 11. The second plane of symmetry intersects the line connecting the fasteners 18.

[0042] The in Fig. 1 The connecting plate 10 shown is made of a plastic; the connecting plate 10 can also be made of another material.

[0043] In Fig. 2 is a perspective view of a top surface 17 of the connecting plate 10 made of Fig. 1 shown. The central passage openings 25 of the connecting elements 18 are particularly easy to see.

[0044] By designing the through-opening 14 as an elongated hole 15, which extends longitudinally from one web 12 to the other web 12, the width of the webs 12 is reduced. This facilitates cutting one of the two webs 12 at the predetermined breaking point 13.

[0045] In the representation from Fig. 2 One of the two webs 12 is cut through at its predetermined breaking point 13. The exposed separation surfaces of the cut web 12 are spaced apart. By varying this space, the connecting sections 11 can be rotated relative to each other around the other, i.e., uncut, web 12. In this way, it is possible to connect two drainage channels 30 at an angle to each other using the connecting plate 10. The distance between the two separation surfaces of the cut web 12 can be adjusted to the desired mounting angle between the drainage channels, depending on the application.

[0046] Fig. 3 shows a connecting plate 10 according to a further embodiment, which differs from the embodiment in Fig. 1 The design differs in the plan view of the abutments 21 and in the recesses 24 of the extensions 19. The remaining features essentially correspond to the features of the embodiment from Fig. 1 .

[0047] In contrast to the embodiment from Fig. 1 The abutments 21 have a substantially straight plan. The abutment 21 thus extends between the connecting element 18 and the other connecting section 11 substantially perpendicular to the line connecting the two connecting elements 11.

[0048] The tubular extensions 19 differ from the embodiment in that they Fig. 1 Each extension 19 has four recesses 24. The recesses 24 are slot-shaped and arranged evenly distributed radially and circumferentially. They extend over the entire length of the extension 19 through the connecting plate 10 to the upper surface 17. The recesses 24 thus divide the tubular geometry of the extension 19 into four channel-shaped parts.

[0049] Fig. 4 shows a perspective view of a top surface 17 of the connecting plate made of Fig. 3 . The recesses 24 are particularly easy to see here, which are arranged radially around the passage openings 25 and thus widen the passage openings 25 in a cross shape in the radial direction.

[0050] Fig. 5 Figure 1 shows a perspective view of a drainage channel 30 according to an embodiment without a connecting plate 10. An open end face 33 of the drainage channel 30 is shown.

[0051] The drainage channel 30 comprises a channel base 31 and two side walls 32 adjoining the channel base 31, which are arranged at a substantially right angle to the channel base 31. The channel base 31 has a counter-connecting element 34 and a fixing element 35 on its open end face 33. The drainage channel 30 comprises a further counter-connecting element 34 on one of the open end faces 33 shown, which is also open.

[0052] The counter-connecting element 34 and the fixing element 35 are arranged at a relatively short distance from the end face of the drainage channels 30. The distance of the counter-connecting element 34 and the fixing element 35 from the end face of the channel is essentially the same. Other arrangements are possible.

[0053] The fixing element 35 of the channel base 31 is located at a distance equal to or greater from one of the two side walls 32 of the drainage channel 30 than the counter-connecting element 34. In other words, the counter-connecting element 34 is located at a distance equal to or closer to one of the two side walls 32 than the fixing element 35. The counter-connecting element 34 is located at a distance from one of the two side walls 32 that essentially corresponds to the distance of the counter-connecting element 34 from the end face of the drainage channel. The counter-connecting element 34 is therefore located at a relatively small distance from the end face of the channel and from one of the side walls 32. Other arrangements are possible.

[0054] The in Fig. 5 The drainage channel 30 shown is height-adjustable, meaning that the side walls 32 can be adjusted in height. The drainage channel 30 can also be designed differently, for example, not height-adjustable.

[0055] In Fig. 6 This is a perspective view of drainage channel 30. Fig. 5 , however, with the connecting plate 10, shown. The connecting plate 10 is connected to the channel base 31 of the drainage channel 30. Specifically, one of the two connecting elements 18 of the connecting plate 10 is connected to the counter-connecting element 34 of the channel base 31. The other connecting element 18 of the connecting plate 10 is fixed by the fixing element 35 of the channel base 31.

[0056] Such an arrangement of the connecting plate 10 on the channel base 31 is particularly advantageous before assembly, for example, during transport to the construction site. Because one connecting element 18 is already connected to the corresponding connecting element 34 of the channel base 31, this connection, and thus a significant work step, is eliminated during on-site assembly. This considerably simplifies the assembly or connection of two drainage channels 30. The fixing element 35 of the channel base 31 secures the connecting plate 10 to the channel base 31. The connecting plate 18 is thus protected within the drainage channel 30. This prevents damage to the connecting plate 10, for example, during loading and unloading as well as during transport of the drainage channel 30.

[0057] The mirror-symmetrical design of the connecting sections 11 facilitates the connection, especially the initial connection, of the connecting plate 10 to the channel base 31 of the drainage channel 30, for example, before transport. This is because both connecting elements 18 can serve both for connection with the mating connecting element 34 and for fixation by the fixing element 35. Therefore, due to its mirror symmetry, the connecting plate 10 can be used equally well in two different orientations, thus simplifying assembly.

[0058] Fig. 7 shows a cross-section through the drainage channel 30 made of Fig. 6 The connecting plate 10 is shown in longitudinal section, i.e. in a section through both connecting means 18.

[0059] The counter-connecting element 34 of the channel base 31 forms a hollow body 37 open on one side, wherein the hollow body 37 is open on an outer side of the drainage channel 30, i.e., on a side opposite the connecting plate 10. The counter-connecting element 34 thus forms a raised section of the channel base 31 with a substantially circular plateau, wherein a central through-bore 36 is formed in the middle of the plateau.

[0060] One of the two connecting sections 11 rests on the plateau. The connecting element 18 of this connecting section 11 extends with its extension 19 through the central through-bore 36 of the mating connecting element 34. The undercut 20 of the extension 19 is located in the hollow body 37 of the mating connecting element 34. The central through-bore 36 of the mating connecting element 34 has a smaller diameter than the radially circumferential undercut 20 of the extension 19. In this way, the undercut 20 engages behind the inner circumference of the central through-bore 36 and is thus in the locked position.

[0061] The hollow body 37 of the mating connector 34, with its central through-hole 36, forms a snap-fit ​​receptacle for the snap-fit ​​connection with the radially circumferential undercut 20 of the extension 19. Such a snap-fit ​​connection reduces assembly effort. To connect the connector 18 to the mating connector 34, the extension 19 simply needs to be pressed through the central through-hole 36 into the hollow body 37 until the undercut 20 of the extension 19 engages behind the inner circumference of the central through-hole 36. The extension 19 can be pressed in manually, so no additional tool is required. The lateral recesses 24 in the extension 19 allow for easy release of the snap-fit ​​connection.For this purpose, only the two channel-shaped halves of the extension 19 need to be pressed together so that the extension 19 with the undercut 20 can be pulled out of the locking receptacle of the counter-connecting element 34.

[0062] The fixing element 35 of the channel base 31 forms a through-hole in the channel base 31. The extension 19 of the connecting element 18, which is not connected to the counter-connecting element 34, lies with its tip in this through-hole of the fixing element 35.

[0063] The extension 19 thus extends partially into the through-hole of the fixing element 35, preventing movement of the connecting plate 10, in particular rotation of the connecting plate 10 about the counter-connecting element 34, in the plane of the plate. In this way, the connecting plate 10 is fixed to the channel bottom 31 of the drainage channel 30 by the fixing element 35.

[0064] Both abutments 21 rest with their bearing surfaces on the channel base 31 and thus absorb compressive forces that act, for example, on the top of the connecting plate during assembly. This relieves both connecting elements 18 and thus prevents damage to the connecting element and / or the drainage channel. The abutment 21 of the fixed connecting section 11 also prevents the connecting element 18 from sliding too far into the through-hole of the fixing element 35, thus preventing further damage or an unwanted engagement of the undercut 20.

[0065] In longitudinal section of the connecting plate 10 made of Fig. 7 The chamfers 22 of the connecting sections 11 are clearly visible. The chamfers 22 facilitate the release of the connecting section 11, which is fixed to the channel base 31. This is because the chamfer 22 on the connected section 11 increases the stroke when lifting the fixed connecting section 11 (indicated by the two opposing arrows pointing outwards on the connecting plate 10). Furthermore, the chamfer 22 on the fixed connecting section 11, by increasing the distance from the channel base 31, facilitates reaching behind the fixed connecting section 11.

[0066] If the connecting plate 10 is lifted in the manner described above (indicated by the dashed outer contour of the connecting plate 10), the fixing of the connecting section 11 by the fixing element 35 is released. From this position, the connecting plate 10 can be rotated, for example, about the counter-connecting element 35, i.e., out of or into the plane of the drawing.

[0067] Fig. 8 shows another perspective view of drainage channel 30 from Fig. 6 , wherein one of the two connecting sections 11 is connected to the channel bottom 31 of the drainage channel 30 and the other connecting section 11 protrudes from the open end face 33 of the drainage channel 30.

[0068] Since the connecting elements 18 are each adapted to rotatably connect the connecting section 11 to the channel base 31, the connecting plate 10 can be easily removed from the position of the drainage channel 30 by rotating it around the counter-connecting element 34. Fig. 6 and Fig. 7 into the position from Fig. 8 transported (indicated by the curved arrow). The rotatable connection between connecting plate 10 and drainage channel 30 thus makes it possible to unscrew the connecting section 11, which was previously fixed to the channel base 31, from the open end face 33 of the drainage channel 30, in order, for example, to connect this connecting section 11 to a counter-connecting element 34 of another drainage channel 30.

[0069] To enable both aligned and angled installation or connection of two drainage channels 30, the counter-connecting element 34 of the channel base 31 is positioned as close as possible to the side wall 32. The round outer contour 23 of the connecting sections 11 reduces the minimum possible distance between the connecting section 11 and the side wall 32.

[0070] The two webs 12 increase the stiffness of the connecting plate 10 when the connecting plate 10 is rotated in the plane of the plate about a connecting element 18 connected to a counter-connecting element 34. This stiffness is further increased by the design of the through-opening 14 as an elongated hole 15, which increases the distance between the two webs 12.

[0071] Fig. 9 Figure 1 shows a perspective view of a channel system according to an embodiment of the invention. Two drainage channels 30 are arranged in alignment with each other and connected by a connecting plate 10. For this purpose, both connecting elements 18 of the connecting plate 10 are connected to a corresponding connecting element 34 of the channel base 31 of each drainage channel 30.

[0072] As in Fig. 9 As can be clearly seen, the drainage channels 30 each have a counter-connecting element 34 on both open end faces 33. A fixing element 35, however, is only provided on one of the two open end faces 33, thus avoiding additional manufacturing effort.

[0073] Fig. 10 shows a perspective view of the gutter system from Fig. 9 with three drainage channels arranged at an angle to one another. Two drainage channels are connected by a connecting plate 10, whereby both connecting elements 18 of the connecting plate 10 are connected to a corresponding connecting element 34 of each drainage channel 30. The web 12 of the connecting plate 10 facing the obtuse angle of the angled arrangement of the drainage channels 30 is cut through. Due to the cut webs 12, the connecting sections 11 of each connecting plate 10 can be rotated relative to each other about the other, i.e., uncut, web 12. In this way, an angled arrangement of the drainage channels 30 is made possible. Bezugszeichenliste
