Description

Technical Field

[0001] The invention relates to a connecting device for connecting a gutter element for a drainage system to a connecting body which is correspondingly shaped at its ends and is connected to the gutter element in the installed state. A device according to the prior art is known, for example, from DE 10 2005020 753 A1. Background Art

[0002] Connecting elements between drain grooves are generally known in the prior art. They are generally used to establish a tight connection between drain grooves. Since drain grooves are generally subject to heavy loads, it is sensible to compensate for the movement of the drain grooves by the connecting element in order to avoid damage to the drain grooves. For example, a connecting element for establishing a tight connection between drain grooves is known from DE 10 2005 020753 A1 mentioned at the outset. However, the disadvantage here is that the movement of the drain grooves cannot be compensated. Summary of the invention

[0003] The object on which the present invention is based is to provide a connecting device for connecting trough elements, which, on the one hand, establishes a sealed connection between the trough elements and, on the other hand, compensates for the movement of the trough elements. In addition, the present invention is based on the object of providing a drainage system having a connecting device for connecting trough elements.

[0004] According to the invention, this object is achieved by one of the subjects according to the invention. With regard to the drainage system, this object is achieved by one of the subjects according to the invention.

[0005] In particular, the object is achieved by a connecting device for connecting a trough element for a drainage system to a connecting body, which is correspondingly shaped at its ends and is connected to the trough element in the installed state. The connecting body is formed by at least two connecting elements, which are connected to each other in the installed state so that the connecting elements can move relative to each other along and / or transversely to the longitudinal axis of the connecting body in order to absorb movements of the trough element, in particular in all spatial directions. In this case, at least one sealing element for sealing is arranged between the connecting elements and can be deformed in order to follow the relative movement of the connecting elements.

[0006] The invention has the advantage that a sealed connection can be established between the trough elements and compensation for movements of the trough elements is possible.

[0007] Here, the movement of the trough element can be transmitted to the connecting device. For this purpose, the connecting device is advantageously fixedly connected to the trough element in the mounted state. For example, the ends of the connecting device or the connecting body can be connected to the trough element in a materially compatible manner. Thereby, the movement of the trough element can be transmitted to at least two connecting elements of the connecting body.

[0008] Furthermore, the connecting elements are connected to each other in the mounted state so that a relative movement between the connecting elements is possible. This means that the movement of the trough element can be absorbed and compensated by the connecting element. Damage to the trough element can be avoided or reduced by the movement compensation.

[0009] Particularly preferably, the present invention enables the absorption and compensation of movements of the trough element in all spatial directions. In this case, movements along and transversely to the longitudinal axis of the connecting body can advantageously be absorbed. This is preferably understood to mean that upward and downward movements in a direction that is essentially vertical in the installed position can be absorbed. In addition, absorption of movements in a direction that is essentially horizontal in the installed position is possible, which extends transversely to the longitudinal axis of the connecting body. In addition, movements along the longitudinal axis can be absorbed, wherein the trough elements can move towards each other or away from each other. It is additionally advantageous here that expansions of the trough element due to temperature fluctuations can be compensated.

[0010] At this point it should be pointed out that a movement along and / or transversely to the longitudinal axis or in the horizontal or vertical direction does not mean a strictly straight movement process. Rather, it should be stated that movements in different spatial directions can be absorbed or compensated. In other words, a rough direction along which the movement absorption can take place should be stated. In other words, all movement directions between the direction transversely to and along the longitudinal axis are advantageously compensated.

[0011] In order to establish a sealed connection, at least two connecting elements are connected to each other via a sealing element in the mounted state. This can prevent liquid from flowing out of the connecting device. In addition, the sealing element can be deformed in order to follow the relative movement of the connecting elements and thus absorb the movement of the groove element. In other words, the relative movement of the connecting elements causes a deformation of the sealing element. Therefore, the sealing element fulfills a dual function.

[0012] The sealing element is advantageously deformable so as to follow the movement of the connecting element along and transversely to the longitudinal axis, wherein the sealing connection between the connecting elements is maintained.Therefore, the sealing element is constructed so that the sealing element can follow the longitudinal and / or transverse movement of the groove element.

[0013] In addition, the deformation of the sealing element is advantageously reversible. For this purpose, the sealing element is preferably elastically deformable. This is preferably understood to mean that the connecting device can react to and compensate for changes in the load acting on the groove element and the resulting movement of the connecting element.

[0014] Preferred embodiments of the present invention are given below.

[0015] Preferably, at least two connecting elements can move relative to each other up to 15mm, preferably 5mm, in a direction substantially vertical in the installed position and / or transverse to the longitudinal axis. This is preferably understood to absorb movements up to 15mm, preferably 5mm, in the vertical direction. In addition, it is feasible to absorb movements up to 15mm, preferably 5mm, in a horizontal direction extending transversely to the longitudinal axis of the connector. Advantageously, the strong movement of the groove element can be absorbed by the connecting element. It is feasible that the connecting elements can move relative to each other by different magnitudes. Therefore, the connecting elements can move relative to each other transversely to the longitudinal axis, for example, 1mm to 5mm, especially up to 6mm, especially up to 7mm, especially up to 8mm, especially up to 9mm or especially up to 10mm.

[0016] Furthermore, at least two connecting elements can preferably be moved relative to each other along the longitudinal axis up to 20 mm, preferably 6 mm. Here, the groove elements can be moved towards each other or away from each other up to 20 mm, preferably 6 mm. It is possible that expansions or contractions of the groove elements due to temperature fluctuations can be compensated. It is possible that the connecting elements can be moved relative to each other by different amounts. Thus, the connecting elements can be moved transversely to the longitudinal axis towards each other or away from each other by, for example, 1 mm to 6 mm, in particular up to 7 mm, in particular up to 8 mm, in particular up to 9 mm or in particular up to 10 mm.

[0017] In another preferred embodiment, at least two connecting elements have a butt joint at at least one end side for a sealable transition between two connecting elements arranged against each other in the installed state. In other words, the butt joints of the connecting elements can be arranged against each other / arranged at each other (anside angeordnet) so that a sealed connection can be established between the connecting elements. It is advantageous here that the butt joint has a simple design in order to arrange the connecting elements against each other and to connect them in a sealing manner.

[0018] Furthermore, the abutment surface of the connecting element advantageously has at least one, in particular circumferential, groove for accommodating the sealing element, which groove is in particular L-shaped. The groove ensures simple and correct positioning of the sealing element. Particularly preferably, the groove is L-shaped in order to ensure a secure placement of the sealing element.

[0019] Preferably, the sealing element is connected to the groove of at least one connecting element in a materially, forcefully and / or form-fitting manner in the installed state, in particular is glued into the groove. This is preferably to be understood as meaning that the sealing element can only be fixedly connected to one of the two connecting elements of the connecting body. The sealing element can only be inserted into the other of the two connecting elements. This allows for a simple installation of the connecting device.

[0020] Particularly preferably, the sealing element has at least one deformation section, which can be deformed to follow the relative movement of the connecting element, and the sealing element has at least one fastening section for anchoring the sealing element in the groove. The sealing element preferably has fastening sections at its axial ends, respectively, for engaging in the groove. A deformation section can be provided between two fastening sections, which transitions into the fastening section at its ends. In other words, the deformation section can be provided between two fastening sections. By means of the simple construction of the sealing element, on the one hand, it is ensured that the sealing element is prevented from sliding. On the other hand, by means of the ability of the deformation section to follow the movement of the connecting element, it is ensured that movement absorption is achieved.

[0021] Further preferably, the deformation section has a curved shape in order to produce a movement play of the connecting element transversely to and / or along the longitudinal axis. In other words, the deformation section is advantageously configured so that it can follow the movement of the connecting element.

[0022] The sealing element can be designed as a strip seal or a double lip seal, in particular as a double P-lip seal, which is deformable to absorb the movement of the connecting element. Advantageously, conventional sealing elements such as strip seals or double lip seals can be used to establish a sealed connection between the connecting elements and to absorb the movement of the groove element.

[0023] In another preferred embodiment, the abutment surface of the connection element has at least one recess, in particular four recesses, for accommodating at least one safety plug, in particular four safety plugs. Particularly preferably, four safety plugs are provided, which are arranged between the two connection elements in the installed state. The safety plug can be designed cylindrically. In order to accommodate the safety plugs, four recesses can be provided on the abutment surfaces of the two connection elements, respectively. A reliable connection can be established between the connection elements by means of the safety plugs.

[0024] The safety plug can be fixedly connected to the recess of the abutment surface in the installed state, in particular connected in a material-fitting, force-fitting and / or form-fitting manner, in order to limit the movement of the connecting element along the longitudinal axis. This should preferably be understood to mean that the safety plug is advantageously fixedly connected to the two connecting elements of the connecting body. As a result, the maximum spacing between the connecting elements can be achieved in a simple manner within the range of the movement clearance along the longitudinal axis. In other words, the movement of the connecting element along the longitudinal axis is advantageously limited by the maximum extension of the safety plug.

[0025] Furthermore, the safety plug is advantageously formed of a flexible material, in particular rubber, which can be deformed so that two connecting elements arranged against each other in the installed state can move relative to each other along the longitudinal axis. This is preferably understood to mean that the safety plug is compressible when the connecting elements move toward each other along the longitudinal axis. Furthermore, the safety plug can be deformable transversely to the longitudinal axis of the connecting body. In other words, the safety plug can follow the movement of the connecting element along and / or transversely to the longitudinal axis. In this way, a reliable connection between the connecting elements can be ensured while absorbing the movement.

[0026] In addition, at least two connecting elements have a substantially U-shaped or V-shaped inner surface for guiding liquid, which inner surface is particularly constituted correspondingly with the inner surface of the trough element. Advantageously, the connecting element or the connector are constituted to connect the trough element and to guide the liquid.

[0027] The connecting body, in particular at least two connecting elements, are preferably formed by concrete or polymer concrete, plastic or metal. Advantageously, the connecting body can be formed by the same material as the groove element, so that high stability can be achieved.

[0028] Furthermore, the invention relates to a drainage system having at least two trough elements which are connected by means of a connecting device according to the invention, wherein in the installed state movements of the trough elements can be absorbed by the connecting device, in particular in all spatial directions.

[0037] Figure 7 Shown according to Figure 1 Schematic view of the drainage system of the connection device. DETAILED DESCRIPTION

[0038] The same reference numerals are used below for identical or identically acting components.

[0039] Figure 1 An embodiment of a connecting device 1 according to the invention for connecting trough elements 100 is shown. This relates to the use of the connecting device 1 for forming a trough line for draining a walkable or drivable surface. In particular, the connecting device 1 for connecting trough elements 100 for drainage systems for roads is used in tunnel construction. Other applications are possible. Thus, the connecting device 1 can be used, for example, in a drainage system for draining roads on bridges or other buildings.

[0040] Usually, according to Figure 1 The connecting device 1 is suitable for installation in the ground, in particular in a traffic surface.

[0041] exist Figure 1 As can be seen in the figure, the connecting device 1 has a connecting body 10. The connecting body 10 has essentially the same shape as the groove member 100. In other words, the connecting body 10 can be configured as an extension of the groove member 100.

[0042] Figure 1 It is also shown that the connecting body 10 is shaped correspondingly at its ends 11a, 11b. This is to be understood as meaning that the two ends 11a, 11b of the connecting body 10 are designed or shaped identically. This allows the connecting bodies 10 to be used interchangeably.

[0043] also, Figure 7It is shown that the ends 11a, 11b of the connector 10 are connected to the trough member 100 in the installed state. Here, each end 11a, 11b of the connector 10 is connected to the trough member 100. Specifically, the connector 10 is fixedly connected to the trough member 100. Here, there can be a material connection between the ends 11a, 11b of the connector 10 and the ends of the trough member 100. Other types of connection are possible. Thus, the connector 10 and the trough member 100 can, for example, be butted against each other, i.e., butted against each other. In other words, the connector 10 and the trough member can be connected to each other detachably and / or form-fittingly.

[0044] from Figure 1 It can be seen from the figure that the connecting body 10 is formed by two connecting elements 12a, 12b. In other words, the connecting body 10 is constructed in two parts or consists of two connecting elements 12a, 12b. Here, the end sides of the connecting elements 12a, 12b are arranged against each other in the installed state. In addition, the end sides of the connecting elements 12a, 12b are arranged opposite to the ends of the connecting elements 12a, 12b. The ends of the connecting elements 12a, 12b are connected to the groove element 100 in the installed state.

[0045] Figures 3 to 6 It is also shown that the connecting elements 12a, 12b are connected to one another in the mounted state such that they can move relative to one another along and / or transversely to the longitudinal axis L of the connecting body 10. Here, the movement of the connecting elements 12a, 12b can take place along and transversely to the longitudinal axis L. In particular, the connecting elements 12a, 12b can absorb movements of the trough member 100 in all spatial directions. In other words, movement compensation in all spatial directions is possible.

[0046] therefore, Figure 3 The movement of the connecting elements 12a, 12b in a substantially vertical direction in the installed position is shown. Here, the movement in the vertical direction can be understood as the upward or downward movement of the connecting elements 12a, 12b in the installed position. In addition, the movement in the vertical direction corresponds to a movement transversely or perpendicularly to the longitudinal axis L of the connecting body 10.

[0047] exist Figure 3 (section on the left), the connecting elements 12a, 12b are arranged at the same height, ie they are in the rest state. Figure 3 (Center sectional view) shows two connecting elements 12a, 12b in a state offset from each other. Here, one of the two connecting elements 12a, 12b is arranged higher than the other connecting element. Figure 3 The movement of the groove element 100 (not shown in the figure) is absorbed by the relative movement of the connecting elements 12a, 12b transversely to the longitudinal axis L. Figure 3 The connecting elements 12a, 12b are shown in another state offset relative to one another (section on the right).

[0048] also, Figure 5 The movement of the connecting elements 12a, 12b along the longitudinal axis L is shown. Figure 5 It can be seen in (section on the left) that there is a gap or a clearance between the two connecting elements 12a, 12b. Figure 5 (The right-hand section) shows that the connecting elements 12a, 12b are arranged directly against each other. Therefore, the connecting elements 12a, 12b are connected to each other so that they can move toward each other or away from each other. Figure 5 The movement of the trough member 100 (not shown) is absorbed by the relative movement of the connecting elements 12a, 12b along the longitudinal axis L.

[0049] In addition, Figure 6 1 shows the movement of the connecting elements 12a, 12b in a substantially horizontal direction in the installed position, which direction extends transversely to the longitudinal axis L. It can be seen that the connecting elements 12a, 12b are offset relative to each other. Figure 6 The movement of the trough element 100 (not shown) is absorbed by the relative movement of the connecting elements 12a, 12b transversely to the longitudinal axis L.

[0050] At this point it should be noted that the connection elements 12a, 12b are Figure 3 , Figure 5 and Figure 6 The relative movements shown in can occur simultaneously or independently of each other. Here, the trough member 100 can be absorbed along and transverse to the movement of the longitudinal axis L, or the connecting elements 12a, 12b can be along and transverse to the longitudinal axis L movement.

[0051] exist Figures 3 to 6 As can be seen in the figure, a sealing element 13 for sealing is arranged between the connecting elements 12a, 12b. The sealing element 13 is used to form a fluid-tight transition between the two connecting elements 12a, 12b.

[0052] also, Figures 3 to 6 It is shown that the sealing element 13 is deformable so that it can follow the relative movement of the connecting elements 12a, 12b. In particular, the sealing element 13 is suitable for following the movement of the connecting elements 12a, 12b transversely and / or perpendicularly to the longitudinal axis L.

[0053] Figure 3 and Figure 4 It is clearly shown that the sealing element 13 follows the movement of the connecting elements 12a, 12b in a substantially vertical direction in the installed position. Figure 4 (section on the left) shows the sealing element 13 in the undeformed state. Figure 4 (Center section) shows the sealing element 13 in a deformed state. In this case, the relative movement of the connecting elements 12a, 12b causes a deformation of the sealing element 13. It can be seen that the sealing element 13 is deformed transversely to the longitudinal axis L. Figure 4 (section on the right) shows the sealing element 13 in a further deformed state.

[0054] also, Figure 5 It is shown that the sealing element 13 is deformed when the connecting elements 12a, 12b are moved along the longitudinal axis L. Figure 5 The sealing element 13 is shown in the undeformed state in (section on the left). It can be seen that the sealing element 13 fills the gap between the connecting elements 12a, 12b and ensures a sealed connection. Figure 5 (Cross-section on the right) shows the sealing element 13 in a deformed state. Here, the sealing element 13 is compressed when the connecting elements 12a, 12b move toward each other along the longitudinal axis L. In other words, the sealing element 13 is pressed together or compressed when the connecting elements move toward each other. If the connecting elements 12a, 12b move away from each other along the longitudinal axis L, the sealing element 13 stretches.

[0055] exist Figure 6 , the sealing element 13 follows the movement of the connecting elements 12a, 12b in a substantially horizontal direction in the installed position, which direction is transverse to the longitudinal axis L. It can be seen that the sealing element 13 is deformed by the movement of the connecting elements 12a, 12b transverse to the longitudinal axis L.

[0056] It should be noted again that the sealing element 13 Figures 3 to 6 The deformations shown in the figure can occur simultaneously or independently of each other. In other words, the sealing element 13 can be deformed along and transversely to the longitudinal axis L so that it can follow the movement of the connecting elements 12a, 12b. As a result, the movement of the groove element 100 in all spatial directions can be absorbed.

[0057] Figure 3 and Figure 6It is also shown that the two connecting elements 12a, 12b can be moved relative to each other up to 5mm in a direction substantially vertical in the installed position and / or transverse to the longitudinal axis L. This should be understood as the movement of the sealing element 13 following the connecting elements 12a, 12b transverse to the longitudinal axis L up to 5mm. It is feasible that the connecting elements 12a, 12b can move relative to each other by different amounts. Therefore, the connecting elements 12a, 12b can be moved relative to each other transverse to the longitudinal axis L, for example, up to 6mm, up to 7mm, up to 8mm, up to 9mm or up to 10mm. Alternatively, the connecting elements can be moved relative to each other transverse to the longitudinal axis, for example, 1mm to 2mm, 1mm to 3mm or 1mm to 4mm.

[0058] exist Figure 6 It can be seen that the two connecting elements 12a, 12b can move up to 6mm relative to each other along the longitudinal axis L. Specifically, the connecting elements 12a, 12b can move toward each other or away from each other. This should be understood as the sealing element 13 can follow the movement of the connecting elements 12a, 12b along the longitudinal axis L up to 6mm. It is feasible that the connecting elements 12a, 12b can move different values ​​along the longitudinal axis L. Therefore, the connecting elements 12a, 12b can move toward each other or away from each other along the longitudinal axis L, for example, up to 7mm, up to 8mm, up to 9mm or up to 10mm. Alternatively, the connecting elements can move relative to each other along the longitudinal axis, for example, 1mm to 2mm, 1mm to 3mm, 1mm to 4mm or 1mm to 5mm.

[0059] also, Figure 2 It is shown that the connecting elements 12a, 12b have abutment surfaces 14 at the end sides for a sealable transition between the two connecting elements 12a, 12b which are arranged in contact with one another in the assembled state. Figure 1 It is also shown that the contact surfaces 14 are arranged in contact with one another, so that a tight connection is produced between the connecting elements 12 a , 12 b .

[0060] exist Figure 2 , it is shown that the abutment surface 14 of the connecting elements 12a, 12b has a groove 15 for accommodating the sealing element 13, so as to ensure the correct positioning of the sealing element 13. Here, the abutment surface 14 of the two connecting elements 12a, 12b has a groove 15. In addition, the groove 15 is formed circumferentially.

[0061] exist Figure 4 As can be seen in FIG. 1 , the groove 15 is L-shaped. Other geometric shapes of the groove 15 are possible. Usually, the shape of the groove 15 can be matched to the sealing element 13.

[0062] In accordance with Figures 1 to 7In the embodiment of the present invention, the sealing element 13 is fixedly connected to the groove 15 of one of the two connecting elements 12a and 12b. Specifically, the sealing element 13 is connected to the groove 15 of the connecting elements 12a and 12b by material fit. This should be understood as the sealing element 13 being glued into the groove 15 of only one connecting element 12a and 12b on one side. The sealing element 13 is detachably connected to the other connecting element of the two connecting elements 12a and 12b, that is, the sealing element 13 is inserted into the groove 15 of the other connecting element 12a and 12b. Alternatively, it is feasible that the sealing element 13 is fixedly connected to the two connecting elements 12a and 12b. Here, the sealing element 13 can be glued into the groove 15 of the two connecting elements 12a and 12b. In other words, the sealing element 13 can be connected to the connecting elements 12a and 12b by material fit on both sides.

[0063] from Figure 4 As can be seen in the figure, the sealing element 13 has a deformation section 16 and a fastening section 17. It can be seen that the deformation section 16 can be deformed in order to follow the relative movement of the connecting elements 12a, 12b. The fastening section 17 is used to anchor the sealing element 13 in the groove 15. Therefore, only a part of the sealing element 13, namely the deformation section 16, is deformable and is designed to follow the movement of the connecting elements 12a, 12b.

[0064] In addition, Figure 4 It can be clearly seen in FIG. 1 that the deformation section 16 has a curved shape in order to create a movement gap for the connecting elements 12a, 12b transversely to and / or along the longitudinal axis L. In particular, the deformation section 16 is designed so that it can follow the movement of the connecting elements 12a, 12b. Figure 4 In the exemplary embodiment, the deformation section 16 has a U-shaped geometry. Other shapes of the deformation section 16 are possible.

[0065] The sealing element 13 is configured as a double-lip seal. Specifically, the sealing element 13 is configured as a double P-type lip seal. This sealing ring is configured to be deformable to absorb the movement of the connecting elements 12a, 12b.

[0066] In addition, according to Figures 1 to 7 The sealing element 13 of the embodiment of the invention is formed of rubber or EPDM (ethylene propylene diene monomer). Other materials are possible.

[0067] In accordance with Figure 2In the embodiment of the present invention, the docking surface 14 of the connecting elements 12a, 12b has four recesses 18a-18d for accommodating four safety plugs 19a-19d. The safety plugs 19a-19d are cylindrically designed. In order to accommodate the safety plugs 19a-19d, four recesses 18a-18d are respectively provided on the docking surfaces 14 of the two connecting elements 12a, 12b. Here, the safety plugs 19a-19d can be provided between the connecting elements 12a, 12b, so that a gap is provided between the connecting elements 12a, 12b.

[0068] exist Figure 2 It can be seen that the safety plugs 19a-19d are fixedly connected to the recesses 18a-18d of the docking surface 14 in the installed state. Specifically, each of the four safety plugs 19a-19d is connected to the corresponding recess 18a-18d of the docking surface 14 by material fit. This limits the movement of the connecting elements 12a, 12b along the longitudinal axis L. This should be understood to mean that the movement of the connecting elements 12a, 12b along the longitudinal axis L is limited by the maximum extension of the safety plugs 19a-19d.

[0069] In addition, the four safety plugs 19a-19d are formed of a flexible material. Here, the safety plugs 19a-19d can be deformed so that the two connecting elements 12a, 12b arranged close to each other can move relative to each other along the longitudinal axis L. Here, when the connecting elements 12a, 12b move toward each other along the longitudinal axis L, the safety plugs 19a-19d are compressed. In addition, the safety plugs 19a-19d can be deformed or bent transversely to the longitudinal axis L of the connecting body 10. Thereby, the safety plugs 19a-19d can follow the movement of the connecting elements 12a, 12b along and / or transversely to the longitudinal axis L. Specifically, the four safety plugs 19a-19d are formed of rubber. Other materials of the safety plugs 19a-19d are feasible.

[0070] In addition, Figure 1 It can be seen that the connector 10 or the two connecting elements 12a, 12b have a substantially U-shaped or V-shaped inner surface 20 for guiding the liquid. Here, the inner surface 20 of the connecting elements 12a, 12b is configured correspondingly to the inner surface of the groove member 100.

[0071] The connecting body 10 or the two connecting elements 12a, 12b are formed from polymer concrete or consist of polymer concrete. Alternatively, it is possible that the connecting body 10 or the connecting elements 12a, 12b are formed from other materials, such as concrete or consist of other materials.

[0072] exist Figure 71 shows a drainage system with two trough elements 100, which are connected by a connecting device 1.
