Description

Technical Field

[0001] The invention relates to a channel body of a drainage channel for draining traffic areas, the channel body being made, in particular, of polymer concrete. The invention also relates to a connecting device, an end wall, a drainage channel, an apparatus and a method. Background Art

[0002] A drain channel having a channel body of the aforementioned type is known, for example, from EP 2 899 324 A1. The channel body of the known drain channel comprises a channel bottom and two opposite side walls, each of which has a visible web.

[0003] In parking platforms, parking garages, and / or parking structures, the water-conducting surface can lie above the drivable traffic area. Therefore, the traffic area includes a surface covering as the uppermost paved surface. Drainage channels installed in such environments must meet high requirements. Consequently, the space available for their installation is limited. Consequently, their installation must be carefully planned, as otherwise, weak points in the support structure may emerge. Furthermore, the drainage channel and its components, such as the grates, must be resistant to corrosion, such as that caused by water and chlorides. Therefore, seals and coverings, especially the surface covering, must seal the drainage channel in a fluid-tight manner. Otherwise, fluids could penetrate the support structure through joints or cracks and damage it. In the known prior art, concrete segment joints, as well as butt joints and connecting joints, constitute critical areas that must be permanently fluid-tight and not be used as maintenance joints. Furthermore, the drainage channel must be able to withstand strong mechanical and / or dynamic loads. This means, in particular, that it must be drivable. Overall, the drainage channel must therefore resist the formation of weak points in the support structure, be load-bearing and resistant to corrosion caused by water, oil, fuel and chlorides. Summary of the Invention

[0004] The present invention is therefore based on the object of providing a channel body of the type mentioned at the outset, which is suitable for installation in a floor with a surface covering and adapted to meet the above-mentioned requirements. Furthermore, the present invention is based on the object of providing a connection device, an end wall, a drainage channel, a device and a method for the channel body.

[0005] According to the present invention,

[0006] - the object with respect to the channel body is achieved by one of the subjects according to the invention,

[0007] - the object with regard to the connection device is achieved by one of the subjects according to the invention,

[0008] - the object with regard to the end wall is achieved by one of the subjects according to the invention,

[0009] - the object concerning the drainage channel is achieved by one of the subjects according to the invention,

[0010] - the object concerning the device is achieved by one of the subjects according to the invention,

[0011] The object with regard to the method is achieved by one of the subjects according to the invention.

[0012] Specifically, the object is achieved by a channel body for a drainage channel for draining traffic areas, in particular parking platforms, parking garages, and / or parking buildings, the channel body being made, in particular, of polymer concrete or cement concrete. The channel body comprises a channel bottom and two opposite side walls, wherein the side walls have visible tabs extending in the longitudinal direction of the channel body. In this case, a coating layer for the surface coating is adjacent to each of the visible tabs and is set back from the visible tabs by a step, wherein the coating layer extends continuously in the longitudinal direction of the channel body.

[0013] The channel body according to the invention is suitable for installation in the ground having a low overall height and comprising at least one surface covering.

[0014] The surface coating forms the uppermost paved surface of the traffic area. It protects the support structure from the ingress of fluids. For example, the surface coating can include an epoxy resin-based coating applied to a layer of cast mortar or concrete. Therefore, the channel body is particularly suitable for installation in parking platforms, parking garages, and / or parking structures where the total floor height is limited, such as in the ceilings of multi-story parking structures, where the ceiling also forms the accessible traffic area.

[0015] The channel body is typically made of polymer concrete. For example, polymer concrete is advantageous for installation in mortar or concrete because it and mortar or concrete have approximately the same coefficient of expansion. This allows temperature fluctuations to be compensated for and expansion cracks to be minimized. Alternatively, other materials, particularly non-metallic materials, are possible.

[0016] The flow-conducting area of ​​the channel body is bounded by the channel bottom and the opposing side walls. Each side wall has a visible tab. The visible tab forms the uppermost, upwardly oriented surface of the channel body when installed. More precisely, the visible tab is the uppermost surface of the side wall when installed.

[0017] The covering surface can also be called a covering flange. The covering surface is respectively arranged directly on the visible web. The covering surface is set back from the visible web by a step. More precisely, the covering surface is respectively arranged on the side of the side wall facing away from the flow guide area.

[0018] The step of the coating face receding from the visible tab is advantageous because the coating resin does not enter the channel body. The height is advantageously defined such that it corresponds to the most common construction height of the coating.

[0019] In the partially installed state, the channel body is, for example, up to the coating face, arranged in at least one casting material, for example, casting mortar or another filling or backfill material. In other words, the surface of the coating face or of the coating flange is on one plane with the surface of the filling or backfill material. In the installed state, a surface coating is applied on the grouting mortar and the coating face. The surface coating is here flush with the visible tab.

[0020] Thus, a crack-bridging connection of the channel body onto the surface coating is possible. The coating face prevents a continuous connection joint or crack along the channel body. In other words, the filling or backfill material and the surface coating have two different connection areas or border areas with the channel body. This means that, in the installed state, the surface coating and the filling or backfill material located directly below it next to the side wall are sealed to the connection with the channel element. Thus, an overall, sealed connection is provided as additional security. The coating face also forms a sealing plane between the surface coating and the casting material. The depth of the step of the coating face receding from the visible tab preferably corresponds to the thickness of the surface coating.

[0021] The coating face can achieve that the surface coating is sealed off from the channel body. This means that, by means of the coating face, a continuous, uninterrupted connection joint between the channel body and the ground, through which water, oil, fuel and / or chlorides would otherwise enter and damage the load-bearing structure, can be permanently avoided.

[0022] Preferred embodiments of the application are given herein.

[0023] In order to be suitable for installation in a ground with little construction space, the channel body preferably has a height of between 50 mm and 100 mm, in particular 60 mm.

[0024] In a preferred embodiment, the side wall has a support face for the grating, in particular an inner support face, which, in the installed state, is arranged in the vertical direction between the channel bottom and the visible tab, wherein the coating face is arranged between the support face and the visible tab. The coating face is the outermost face of the channel body. The arrangement between the support face and the visible tab describes the arrangement in the height position in the installed state of the channel body. With this construction, a compact channel body is possible, which is suitable for laying in a thin load-bearing structure. In particular in one embodiment of the channel body, the height of the channel body is between 50 mm and 100 mm, in particular 60 mm.

[0025] In another preferred embodiment, the channel bottom, the supporting surface, the visible web, and the covering surface are parallel to one another. In particular, these surfaces are parallel to the surface of the ground on which the channel body is laid. The parallel visible webs allow the channel body to be easily aligned with the ground surface. Furthermore, the channel body thus exhibits good flow-conducting properties.

[0026] The visible web is preferably closed like the covering surface and is in particular smooth in design.

[0027] The coating layer preferably has a closed and especially smooth surface. A flat surface is possible thus, and the surface hardly needs to be reprocessed. In addition, after the coating is pre-treated, the closed surface simplifies the coating of the surface coating on the coating layer.

[0028] In another particularly preferred embodiment, the distance by which the coating layer is set back from the visible tab is between 1 mm and 10 mm, in particular 5 mm. This allows the coating height to be adapted as needed to different surface systems with surface coatings of varying thicknesses. This means that the channel body can be used with various surface coating systems.

[0029] Particularly preferably, the coating layer extends between 5 mm and 20 mm, in particular 15 mm, in a direction orthogonal to the longitudinal direction of the channel body. In other words, the width of the coating area is between 5 mm and 20 mm. Along the longitudinal extension of the channel body, the coating layer extends parallel to the longitudinal direction of the channel body. Due to the coating layer, the surface coating is not directly connected to the visible tab, but extends over the boundary area between the casting mortar and the channel body. As a result, a crack-bridging connection of the channel body to the surface coating is possible. More precisely, the connection joint produced between the backfill material and the channel body is bridged. The wide coating layer improves the sealing and connection properties between the surface coating and the channel body.

[0030] In a particularly preferred embodiment, the channel body includes anchoring recesses for positively locking the casting material, in particular the backfill material, and is provided on the outer side of the side wall. In the installed state, the anchoring recesses improve the retention of the channel body. They reduce movement of the channel body in the transition region to the adjacent paving section, thereby reducing crack formation in the surface coating due to static and / or dynamic loads.

[0031] Advantageously, the anchoring recess has a recess which is designed such that a free space for receiving a casting material, in particular a backfill material, is formed below the side walls. This makes it possible to easily install the channel body, since the casting material can be easily introduced into the free space.

[0032] To strengthen the structure of the channel body, it is advantageous for the reinforcing elements to be arranged between the anchoring recesses in the longitudinal direction of the channel body. Thus, the stability of the channel body is improved and damage during laying or use is reduced. The reinforcing elements can be designed, for example, as struts or material thickening.

[0033] In an advantageous embodiment, the channel body has a first axial end portion with a lower protrusion and a second axial end portion with an upper protrusion, wherein the length of the upper protrusion in the longitudinal direction of the channel body is smaller than the length of the lower protrusion. This design of the channel body enables a form-fit connection between two identically structured channel bodies.

[0034] Within the scope of the application, a connecting device for a channel body is also disclosed and claimed, wherein the connecting device comprises a first and a second axial end portion of the channel body, wherein the first axial end portion of the channel body is designed to form a form-fit accommodation for a second axial end portion of an identical second channel body, such that a predetermined joint for accommodating adhesive is formed.

[0035] The joint is preferably at least 3 mm to 12 mm, in particular 6 mm, wide and at least 4 mm to 16 mm, in particular 8 mm, deep.

[0036] The connecting device is preferably designed in one piece, in particular integrally, with the channel body. The connecting device is designed to act together with another channel body. Alternatively, the connecting device acts together with an end wall. By means of the one-piece connecting device, maintenance of the joint in the system is dispensed with.

[0037] The connecting device comprises both axial end portions of the channel body. In other words, both axial end portions of the channel body form the connecting device.

[0038] The two different axial end portions enable, for example, two identically structured channel bodies to be arranged form-fit on one another first. Due to the resulting joint for adhesive, which can also be referred to as adhesive joint, it is possible for the two channel bodies to be connected to one another in material fit. The adhesive additionally serves as a sealant. The adhesive thus has the advantage that in this way the two channel bodies can be connected to one another fluid-tight without the need for additional sealing elements. For example, a two-component adhesive can be used as adhesive. The connecting device enables the connection of two channel bodies without the need for screwing or welding.

[0039] In a preferred embodiment, the first axial end of the connecting device comprises a lower protrusion and the second axial end comprises an upper protrusion, wherein the length of the upper protrusion in the longitudinal direction of the channel body is shorter than the length of the lower protrusion. Thus, an accommodating space or recess corresponding to the shape of the lower protrusion is provided below the lower protrusion, and an accommodating space corresponding to the upper protrusion is provided above the lower protrusion.

[0040] The upper and lower projections are thus adapted so that, in the installed state, the upper projection of one channel body rests on the lower projection of the second channel body to form a joint. This ensures that the joint does not extend through the entire channel body. Instead, the joint extends onto the lower projection. This allows for a better sealing of the channel bodies from one another, with the channel bodies being arranged simultaneously to abut one another. This type of laying direction defines a precise adhesive joint in terms of width and height.

[0041] To further improve the sealing between the channel bodies, the lower and upper projections include contact surfaces, each of which has an inclination. In the installed position, the contact surface of the upper projection at least partially points downward, while the contact surface of the lower projection at least partially points upward. The inclination of the contact surface of the lower projection corresponds to the inclination of the contact surface of the upper projection. This allows for simple orientation of the channel bodies. In addition, the contact surfaces are located flatly on each other, thereby improving the positional security between the connected channel bodies.

[0042] The formation of the axial ends allows for precise positioning of the channel bodies. In particular, mounting the channel bodies from above is possible. Mounting from above facilitates the formation of channel routes from a plurality of channel bodies and prevents casting material from penetrating the channel bodies, in particular into the joints, during mounting.

[0043] As another aspect of the present invention, an end wall for a channel body is disclosed and claimed, wherein the end wall is adapted to be connectable with a first or second axial end of the channel body in a form-fitting manner so as to form a joint for an adhesive. The end wall is used to axially close or axially limit an end of the channel body in a fluid-tight manner.

[0044] Thus, the end wall has a profile or geometry adapted to the axial end of the channel body having the above-described connecting device.Thus, the end wall has the same advantages as already described in conjunction with the connecting device.

[0045] Advantageously, the end wall has a coating that corresponds to the coating of the channel body described above. This allows the coating to be provided around the entire system.

[0046] Furthermore, a drain channel with a channel body is disclosed and claimed, wherein the drain channel has a grate made of a non-metallic material, in particular a plastic material. The plastic grate allows the channel body to be constructed without metal, thereby further preventing corrosion caused by water, chlorides, or oil.

[0047] As another aspect of the present invention, a device having at least two channel bodies or having at least two drainage channels is disclosed and claimed.

[0048] Another aspect of the invention relates to a method for installing a device, wherein a channel body is laid into the ground in a recess; a second channel body identical to the channel body is placed onto the channel body from above, so that the contact surfaces touch each other and form a joint; the channel body and the second channel body are connected in a material-fitting manner by introducing an adhesive into the joint; the recess is then filled with a casting material, in particular a casting mortar; and finally a surface coating is applied to the coating surface up to the visible tab, in particular so that the surface coating is flush with the visible tab.

[0049] Alternatively, it is possible that the recess is at least partially filled with a potting compound and the channel body is arranged on the potting compound. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] according to Figure 1 and 2 The channel body 10 is made of polymer concrete and comprises a channel bottom 11 , two side walls 12 and two free axial ends 20 , 21 .

[0071] The side walls 12 each have a visible tab 13 . The visible tab 13 is the uppermost surface of the channel body 10 in the installed state. A cover surface 14 adjoins the visible tab 13 . The cover surface 14 is set back from the visible tab 13 by a step 15 .

[0072] exist Figure 2 As can be seen in the figure, the covering surface 14 is arranged vertically between the visible tab 13 and the support surface 16. The covering surface 14 is parallel to the surface of the visible tab 13. The covering surface 14 is arranged continuously on the visible tab 13. The covering surface 14 has no interruptions and is smooth. The covering surface 14 forms the outermost, upward-pointing surface of the drain channel body 10 in the installed state. The covering surface 14 extends along the entire length of the drain channel body 10.

[0073] The step 15, which sets back the coating 14 from the surface of the visible web 13, has a bevel and a rounded transition to the coating 14. The bevel each has a positive slope starting from the coating 14. In other words, the angle between the coating 14 and the bevel is greater than 90°, in particular 100°.

[0074] The anchoring recess 18 and the reinforcement element 19 are arranged on the side of the side wall 12 of the drain body 10 facing away from the drain bottom 11 .

[0075] The anchoring recess 18 extends parallel to the central longitudinal axis of the drain channel body 10. The anchoring recess 18 is arched in sections transverse to the central longitudinal axis of the drain channel body 10. The arch transitions into an inclined surface that extends outward and upward in the installed state. In the installed position, the anchoring recess 18 is arranged below the cover surface 14 and sectionally below the visible tab 13, creating a free space. Due to the anchoring recess 18, the drain channel body 10 is narrower in the lower region than in the upper region in the installed state.

[0076] The channel body 10 has a reinforcing element 19 at each of the axial ends 20, 21. Preferably, two further reinforcing elements 19 are arranged between the axial ends 20, 21. Alternatively, further reinforcing elements 19 are possible. The anchoring recess 18 is arranged between the reinforcing elements 19. In other words, the reinforcing elements 19 delimit the anchoring recess 18 in the axial direction of the channel body 10. The reinforcing elements 19 are formed in one piece with the channel body 10, in particular integrally. The reinforcing elements 19 are flush with the outer edge of the cladding layer 14 and extend to the underside of the channel bottom 11 in the installed state. In other words, the reinforcing elements 19 do not extend beyond the cladding layer 14 in the lateral direction.

[0077] Figure 3 Shows the installed state according to Figure 1 and Figure 2The trench body 10 is made of polymer concrete. A layer of cast mortar adjoins the trench body. This layer of cast mortar is flush with the cover layer face 14. A surface cover is applied to the cast mortar and the cover layer face. The surface cover is flush with the visible web 13 and covers the boundary area between the trench body 10 and the cast mortar. In one embodiment, the surface cover can comprise, for example, an epoxy resin-based cover layer. Alternatively, other cast materials and surface covers are possible.

[0078] Figure 4 and Figure 5 A free axial end of the trench body 10 is shown. Figure 4 A first axial end 20 is shown. The first axial end 20 has a lower protrusion 22.

[0079] In the installed position, the lower protrusion 22 has a contact face 25 that at least sectionally points upwards. The lower protrusion 24 has a profile that essentially corresponds to the surface profile of the trench body 10. The contact face 25 thus has a step in the region of the side wall 12, in the region of the bearing face 16 and a continuous face in the region of the trench bottom 11. The contact face 25 has a gradient that tapers the axial end of the lower protrusion.

[0080] Figure 5 A second axial end 21 of the trench body 10 is shown. The second axial end 21 has an upper protrusion 23. The upper protrusion 23 has a contact face 25 on the lower side in the installed state. The lower contact face 25 has a gradient that corresponds to the gradient of the contact face 25 of the first axial end 20, respectively. In other words, the profile of the upper protrusion 23 is adapted to the profile of the lower protrusion 22. The first axial end 20 and the second axial end 21 constitute a form-fit for arranging two trench bodies 10 on one another.

[0081] Figure 6 An embodiment of the trench body 10 according to the above figures is shown essentially. Figure 6 The trench body in the has an opening. The opening is a connection opening in order to provide, for example, a drain on the trench body 10. The opening is circular and is provided in the region of the second axial end 21. Other positions for providing the opening are possible.

[0082] Figures 7 to 10 An end wall 26 for the trench body 10 according to Figures 1 to 6 is shown. Figure 7 and 8End wall 26 in the housing is designed to be mounted on first axial end 20 of channel body 10. To this end, end wall 26 has a profile corresponding to second axial end 21. End wall 26 includes a contact surface 25 that corresponds to contact surface 25 of the second axial end of channel body 10 and points downward at least in sections in the installed state. Contact surface 25 is arranged on a raised surface corresponding to upper projection 23.

[0083] Figure 9 and 10 The end wall 26 in the drain channel body 10 is designed to be arranged on the second axial end 21 of the drain channel body 10. For this purpose, the end wall 26 has a lower projection with a contact surface 25 pointing upward at least in sections, which corresponds to the contact surface 25 of the first axial end 20. The contact surface 25 is arranged on a raised surface corresponding to the lower projection 22.

[0084] according to Figures 7 to 10 The end walls 26 each have a visible tab 13 , to which the cladding 14 adjoins and is set back by a step 15 . In the installed state, the cladding 14 and the visible tab 13 of the end wall 26 are flush with the cladding 14 and the visible tab 13 of the channel body 10 .

[0085] Figure 11 and 12 The method steps for laying a channel body 10 are shown. More precisely, two channel bodies 10 are connected to each other. A channel body 10 is arranged on a surface. A further channel body 10 is arranged from above on the channel body 10 arranged on the surface. The further channel body is arranged from above, in other words placed on the stationary channel body.

[0086] exist Figure 13 and 14 In the embodiment, the two channel bodies 10 are arranged on each other in a form-fitting manner. The lower protrusion 22 of the first axial end 20 is longer than the upper protrusion 23 of the second axial end 21. In the installed state, the upper protrusion 23 rests on the lower protrusion 22. The lower protrusion 22 abuts against the second axial end 21. The upper protrusion 23 does not abut against the first axial end 20.

[0087] As a result, a joint 24 is formed between the upper projection 23 and the first axial end 20. The joint 24 is bounded by the surface of the lower projection 22, the end face of the first axial end 20, and the end face of the upper projection 23 of the second axial end 21. In the installed position, the joint 24 is open upward and inward and is open outward in the region where the tab 13 and the cover surface 14 are visible as far as the contact surface 25 of the lower projection 22.

[0088] Figure 15 Show the basis Figures 11 to 14 The device wherein the joint 24 is filled with an adhesive. Figure 15 In the embodiment, two channel bodies 10 are connected to each other in a form-fitting and material-fitting manner. The adhesive layer is flush with the surface of the channel body 10 .

[0089] Figure 16 and 17 The end walls 26 provided on the channel body 10 are respectively shown. Figure 16 An end wall 26 is shown provided at the first axial end 20, and Figure 17 The end wall 26 is shown, which is arranged at the second axial end 21. A joint 24 is formed between the end wall 26 and the axial ends 20, 21, respectively, for receiving an adhesive.

[0090] Figure 18 Two channel bodies 10 connected to each other are shown, at the open axial ends of which an end wall 26 is provided in each case. A grate 17 is arranged in the channel body. The grate 17 is made of plastic and rests on the support surface 16.

[0091] The total height of the channel body 10 in the installed state can be between 50 mm and 100 mm, in particular 60 mm. The width of the channel body 10 can be between 180 mm and 230 mm, in particular 190 mm.

[0092] The polymer concrete and the grating 17 made of plastic can be combined to produce the drainage channel without any metal parts. Therefore, the drainage channel is corrosion-resistant.

[0093] In the installed state, the channel body 10 is embedded in the casting material, preferably the casting mortar, up to the covering surface 14. The surface covering is applied to the casting mortar. The surface covering extends over the casting mortar and the covering surface 14 and is flush with the visible tabs 13. The surface covering covers the boundary area between the casting mortar and the channel body 10. This reduces the possibility of fluids being able to penetrate between the mortar and the channel body 10. This means that crack formation and cracking of the surface covering are prevented. The covering surface 14 forms a sealing surface that improves the tightness of the connection between the channel body 10 and the casting mortar.

[0094] The bevel of the step 15 , which sets the coating 14 back from the visible web 13 , and the rounded transition to the coating 14 allow for simple application of the surface coating to the visible web 13 , while minimizing the formation of cavities in the region of the step 15 , which could lead to cracking of the surface coating.

[0095] The two axial ends 20, 21 form a connecting device. The mating axial ends 20, 21 allow two channel bodies 10 to be easily connected to one another. The second axial end 21 can be placed onto the first axial end 20 from above. The inclination of the contact surface 25 further simplifies installation from above. Due to the inclined, corresponding contact surface 25, the channel bodies 10 can be easily positioned by sliding them into place.

[0096] The upper projection 23 is shorter in the longitudinal direction than the lower projection 22. The two axial ends 20, 21 are designed so that they engage with one another in the assembled or partially assembled state. The shorter upper projection 23 forms a joint 24. Joint 24 is used to accommodate an adhesive for connecting the two drain bodies 10. The adhesive connects the two drain bodies 10 in a material-fitting manner and additionally seals the connection.

[0097] When the channel body 10 is installed, the free space of the anchoring recesses 18 is filled with a casting material, such as casting mortar. In the installed state, the channel body 10 is connected to the surrounding casting mortar in a form-fitting manner via the anchoring recesses 18. The anchoring recesses 18 thus improve the retention of the channel body 10 in the casting mortar and counteract movement of the channel body in the casting mortar caused by dynamic and / or static loads. This reduces the formation of cracks in the surface coating.

[0098] The reinforcement element 19 improves the structural stability of the channel body 10. Furthermore, the reinforcement element 19 delimits the anchoring recess 18 in the axial direction. As a result, in the installed state, movement of the channel body 10 in the longitudinal direction is reduced and crack formation in the surface coating is reduced.

[0099] End wall 26 closes drain body 10 in a fluid-tight manner in the axial direction. The design of end wall 26 enables connection to drain body 10 according to the above-described connecting device. End wall 26 can be placed on drain body 10 from above with a positive fit and subsequently glued via joint 24.

[0100] The aforementioned aspects and embodiments of the present invention contribute to meeting the requirements placed on drainage channels for traffic areas, in particular parking platforms, parking garages, and / or parking structures, which have a surface coating as the uppermost paved surface. The features of the aforementioned aspects and their embodiments particularly improve the sealing properties of the channel body or drainage channel, or the long-term maintenance of the sealing properties.
