Description

Channel body, connecting device, end wall, drain channel, device and method

Technical Field

The invention relates to a channel body of a drain channel for draining traffic areas, which is made in particular of polymer concrete. The invention also relates to a connecting device, an end wall, a drain channel, an arrangement and a method.

Background

Drain channels with channel bodies of the above-mentioned type are known, for example, from EP2899324a 1. The channel body of the known drain channel comprises a channel bottom and two opposite side walls, which each have visible tabs (sichteg).

In the case of parking platforms, parking garages and/or parking buildings, the plane guiding the water can be located on a drivable traffic area. The traffic zone therefore comprises a surface coating as the uppermost pavement. Drain channels that should be installed in such environments must meet high requirements. Thus, the space available for installing the drain channel is limited. The installation of the drain channel must therefore be carefully planned, since otherwise weak points in the carrier may occur. Furthermore, the drain channel and its components, such as the grate, must be corrosion resistant, for example, to water and chloride. The seals and coatings, in particular the surface coatings, must therefore be closed in a fluid-tight manner against the drain channel. Otherwise, fluid may penetrate into the support means through the joint or the crack and damage the support means. In the known prior art, in particular the concrete section joints and the butt joints and connection joints form critical areas which must be permanently liquid-tight and are not allowed as maintenance joints. Furthermore, the drain channel must withstand strong mechanical and/or dynamic loads. This means, in particular, that the drain channel must be drivable thereon. In summary, the drain channel must therefore resist the formation of weak points in the load bearing means, withstand the load and resist corrosion due to water, oil, fuel and chlorides.

Disclosure of Invention

The invention is therefore based on the object of: a channel body of the initially mentioned type is proposed which is suitable for installation in a ground with a surface coating and which is adapted to meet the above-mentioned requirements. The invention is based on the object, inter alia, of providing a connection device, an end wall, a drain channel, an arrangement and a method for a channel body.

According to the present invention, there is provided,

the object with respect to the channel body is achieved by one of the subject-matters according to the invention,

the object with regard to the connecting device is achieved by one of the subject-matters according to the invention,

the object with regard to the end wall is achieved by one of the subject-matters according to the invention,

the object with regard to the drain channel is achieved by one of the subject-matters according to the invention,

the object with respect to the device is achieved by one of the subject-matters according to the invention,

the object with respect to the method is achieved by one of the subject-matters according to the invention.

In particular, the object is achieved by a channel body of a drainage channel for draining traffic areas, in particular parking platforms, parking garages and/or parking buildings, which channel body is in particular made 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, the cladding surfaces for the surface cladding are in each case adjacent to and set back from the visible web by a step, the cladding surfaces extending continuously in the longitudinal direction of the channel body.

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

The surface coating forms the uppermost layer of the traffic zone. The surface coating has the function of protecting the support means against fluid ingress. For example, the surface coating can comprise an epoxy-based coating and be applied to a layer of casting mortar or concrete. The channel body is therefore particularly suitable for installation in parking platforms, parking garages and/or parking buildings, since the total height of the floor is limited in these environments, as is the case, for example, in the ceiling of multi-storey parking buildings, wherein the ceiling at the same time also forms a passable traffic area.

The channel body is in particular made of polymer concrete. For example, polymer concrete is advantageous for installation in casting mortar and concrete because polymer concrete and casting mortar or concrete have nearly the same coefficient of expansion. Temperature fluctuations can thereby be compensated for and expansion cracks can be minimized. Alternatively, other materials, in particular non-metallic materials, are possible.

The flow guiding region of the channel body is bounded by a channel bottom and opposing sidewalls. The side walls each have a visible tab. It can be seen that the webs form the uppermost, upwardly oriented face of the channel body in the mounted state. More precisely, the visible tab is the uppermost face of the side wall when installed.

The cladding face can also be referred to as a cladding flange. The cladding surfaces are each disposed directly on the visible tabs. The overlay is retracted from the visible tab by a step. More precisely, the cladding surfaces are each arranged on a side of the side walls facing away from the flow guiding region.

The step that retracts the cladding layer from the visible tab is advantageous because the cladding resin does not enter into the channel body. The height is advantageously defined such that it satisfies the most common construction height of the cladding.

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

Thus, a crack-bridging connection of the channel body to the surface coating is possible. The cladding surface prevents continuous connection joints or cracks along the channel body. In other words, the fill or backfill material and the surface coating have two distinct junction or boundary regions with the channel body. This means that, in the installed state, the surface coating and the filling or backfill material located below it in the immediate vicinity of the side walls are sealed to the connection with the trench elements. Thus, an integral, sealed connection is provided as additional security. The cladding surface also forms a sealing plane between the surface cladding and the casting material. The depth of the step that retracts the cover layer from the visible web preferably corresponds to the thickness of the surface cover.

The cladding surface makes it possible to sealingly enclose the surface cladding with the channel body. This means that a continuous, uninterrupted connection interface between the channel body and the ground, through which water, oil, fuel and/or chlorides could otherwise enter and damage the carrying means, can be permanently avoided by the covering layer.

Preferred embodiments of the present invention are given herein.

In order to be suitable for installation in floors with a small installation space, the channel body preferably has a height of between 50mm and 100mm, in particular 60 mm.

In a preferred embodiment, the side walls have a support surface for the grate, in particular an inner support surface, which in the installed state is arranged in the vertical direction between the channel bottom and the visible web, wherein the cover layer is arranged between the support surface and the visible web. The cladding face is the outermost face of the channel body. The arrangement between the bearing surface and the visible web describes the arrangement in the height position in the mounted state of the channel body. By this configuration, a compact channel body is possible, which is suitable for laying in a thin carrier. In particular in one embodiment of the channel body, the height of the channel body is between 50mm and 100mm, in particular 60 mm.

In a further preferred embodiment, the channel base, the bearing surface, the visible web and the cladding surface are parallel to one another. In particular, the faces are parallel to the surface of the ground on which the channel body is laid. Parallel visible tabs may allow the channel body to be simply oriented toward the surface of the ground. In addition, the channel body thus has good flow guiding properties.

The visible webs are preferably closed as the cladding surface and are particularly smooth.

The coating surface preferably has a closed and in particular smooth surface. A flat surface is thus possible, which requires little reworking. Furthermore, the closed surface simplifies the application of the surface coating to the coating side after the pretreatment of the coating.

In a further particularly preferred embodiment, the distance by which the cladding surface is set back from the visible web is between 1mm and 10mm, in particular 5 mm. The coating height can thus be adapted to different surface systems of surface coatings having different thicknesses, as required. This means that the channel body can be used for different surface coating systems.

It is particularly preferred that the cladding face extends between 5mm and 20mm, in particular 15mm, in a direction orthogonal to the longitudinal direction of the channel body. In other words, the width of the cladding area is between 5mm and 20 mm. Along the longitudinal extension of the channel body, the cladding face extends parallel to the longitudinal direction of the channel body. Due to the cladding face, the surface cladding does not directly butt onto the visible tabs, but extends over the boundary area between the casting mortar and the channel body. Thus, a crack-bridging connection of the channel body to the surface coating is possible. More specifically, the connecting joint created between the backfill material and the channel body is bridged. The wide coating face improves the sealing and connecting properties between the surface coating and the channel body.

In an especially preferred embodiment, the channel body comprises an anchoring recess (Verankerungstaschen) for form-fitting connection with the casting material, in particular the backfill material, which is arranged on the outer side of the side wall. In the mounted state, the anchoring recess improves the retention of the channel body. The anchoring recesses reduce the movement of the channel body in the transition region to the adjacent laying section and thus reduce the formation of cracks in the surface coating due to static and/or dynamic loads.

The anchoring recess advantageously has recesses which are designed in such a way that a free space for receiving the potting material, in particular the backfill material, is formed below the side walls. Thus, the channel body can be mounted simply, since the casting material can be introduced easily into the free space.

In order to reinforce the structure of the channel body, it is advantageous if a reinforcing element is arranged between the anchoring recesses in the longitudinal direction of the channel body. Thus, the stability of the channel body is improved and damage at the time of laying or use is reduced. For example, the reinforcing element can be designed as a strut or as a material thickening.

In an advantageous embodiment, the channel body has a first axial end with a lower projection and a second axial end with an upper projection, wherein the length of the upper projection in the longitudinal direction of the channel body is smaller than the length of the lower projection. This embodiment of the channel body makes it possible to achieve a form-fitting connection between two channel bodies of identical construction.

Within the scope of the present invention, a connecting device for a channel body is also disclosed and claimed, wherein the connecting device comprises a first and a second axial end of the channel body, wherein the first axial end of the channel body constitutes the second axial end for a form-fitting accommodation of an identical second channel body, such that a predetermined joint for accommodation of an adhesive is formed.

The joint is preferably at least 3mm to 12mm, especially 6mm wide, and at least 4mm to 16mm, especially 8mm deep.

The connecting device is preferably formed integrally, in particular integrally, with the channel body. The connecting device is designed to interact with the other channel body. Alternatively, the connecting device can interact with the end wall. The maintenance joint in the system is omitted by the one-piece connecting device.

The connecting device comprises the two axial ends of the channel body. In other words, the two axial ends of the channel body form the connecting device.

These two different axial ends can be realized: for example, two identically constructed channel bodies are first placed on one another in a form-fitting manner. Due to the resulting joint for the adhesive, which can therefore also be referred to as an adhesive joint, it is possible for the two channel bodies to be connected to one another in a material-fitting manner. The adhesive additionally serves as a sealant. The bonding thus has the following advantages: in this way, the two channel bodies can be connected to one another in a fluid-tight manner without additional sealing elements. For example, a two-component adhesive can be used as the adhesive. The connecting device connects the two channel bodies without screwing or welding.

In a preferred embodiment, the first axial end of the connecting device has a lower projection and the second axial end has an upper projection, wherein the length of the upper projection in the longitudinal direction of the channel body is smaller than the length of the lower projection. Thereby, an accommodation space or a clearance corresponding to the shape of the lower projection is provided below the lower projection, and an accommodation space corresponding to the upper projection is provided above the lower projection.

The upper projection and the lower projection are hereby adapted such that in the mounted state the upper projection of the channel body rests on the lower projection of the second channel body to form the joint. This is achieved: the engagement portion does not extend through the entire channel body. The engaging portion extends to the protruding portion of the lower portion. A better sealing of the channel bodies against each other is thereby possible, wherein the channel bodies are simultaneously arranged in abutment against each other. Such a laying direction defines a precise adhesive joint in width and height.

In order to further improve the sealing of the channel bodies against each other, the lower projection and the upper projection comprise contact surfaces, which have an inclination, respectively. In the mounted position, the contact surface of the upper projection is directed at least partly downwards, and the contact surface of the lower projection is directed at least partly upwards. The inclination of the contact surface of the lower projection corresponds to the inclination of the contact surface of the upper projection. Thereby, a simple orientation of the channel body is possible. Furthermore, the contact surfaces are thereby located flat on one another, so that the positional safety between the connected channel bodies is improved.

By constituting the axial end, a precise positioning of the channel body is possible. In particular, it is possible to mount the channel body from above. Installation from above makes it easy to form the channel course from a plurality of channel bodies and prevents casting material from entering the channel bodies, in particular into the joints, during installation.

As another aspect of the invention, an end wall for a channel body is disclosed and claimed, wherein the end wall is adapted to be form-fittingly connectable with a first or second axial end of the channel body such that a joint for an adhesive is formed. The end wall serves to fluid-tightly axially close or axially restrain the end of the channel body.

Thus, the end wall has a profile or geometry adapted to the axial end of the channel body with the above-mentioned connecting device. The end wall thus has the same advantages as already described in connection with the connecting device.

Advantageously, the end wall has a cladding face corresponding to the cladding face of the channel body. This can be achieved: a cladding layer is disposed around the entire system.

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 channel body can be formed without metal by means of a plastic grate. Corrosion due to water, chloride or oil can be further prevented.

As another aspect of the invention, an apparatus having at least two channel bodies or having at least two drain channels is disclosed and claimed.

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; placing a second channel body identical to the channel body onto the channel body from above such that the contact faces contact each other and form a joint; materially connecting the channel body with the second channel body by introducing an adhesive into the joint; then filling the recess with a casting material, in particular a casting mortar; and finally applying the surface coating to the coating face up to the visible tab, in particular so that the surface coating is flush with the visible tab.

Alternatively, it is possible that the recess is at least partially filled with casting material and the channel body is arranged on the casting material.

Detailed Description

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

The side walls 12 each have a visible tab 13. It can be seen that the tab 13 is the uppermost face of the channel body 10 in the mounted state. The cover surfaces 14 adjoin the visible webs 13 in each case. The cover layer 14 is retracted from the visible tab 13 by a step 15.

In fig. 2, it can be seen that the cover surface 14 is arranged in the vertical direction between the visible web 13 and the bearing surface 16. The cover face 14 is parallel to the face of the visible tab 13. The cover layer 14 is arranged continuously on the visible tab 13. The cladding surface 14 has no interruptions and is formed smoothly. The cladding face 14 forms the outermost, upwardly directed face of the channel body 10 in the mounted state. The cladding layer 14 extends along the entire length of the channel body 10.

The step 15, which retracts the cladding surface 14 from the surface of the visible web 13, has a bevel and a rounded transition to the cladding surface 14. The slopes each have a positive slope from the cladding face 14. In other words, the angle between the cladding face 14 and the bevel is greater than 90 °, in particular 100 °.

The anchoring recesses 18 and the reinforcing elements 19 are arranged on the side of the side walls 12 of the channel body 10 facing away from the channel bottom 11.

The anchoring recess 18 extends in a direction parallel to the central longitudinal axis of the channel body 10. The anchoring recesses 18 are arched in sections in a direction transverse to the central longitudinal axis of the channel body 10. The bulge transitions into an inclined surface which extends outward and upward in the installed state. In the installed position, the anchoring recess 18 is arranged below the cladding surface 14 and in sections below the visible web 13, so that a free space is formed. The channel body 10 is narrower in the lower region than in the upper region in the mounted state due to the anchoring recess 18.

The channel body 10 has a reinforcing element 19 at the axial ends 20, 21, respectively. Preferably, two further reinforcing elements 19 are provided between the axial ends 20, 21. Alternatively, further reinforcing elements 19 are possible. The anchoring recesses 18 are arranged between the reinforcement elements 19. In other words, the reinforcing element 19 delimits the anchoring recess 18 in the axial direction of the channel body 10. The stiffening element 19 is formed integrally, in particular monolithically, with the channel body 10. The stiffening elements 19 are flush with the outer edge of the cover layer 14 and extend in the mounted state up to the underside of the channel bottom 11. In other words, the reinforcing element 19 does not extend beyond the cover face 14 in the transverse direction.

Fig. 3 shows the channel body 10 according to fig. 1 and 2 in the mounted state. The channel body 10 is made of polymer concrete. A layer of casting mortar is adjacent to the channel body. This layer of casting mortar is flush with the overlay surface 14. The surface coating is applied to the casting mortar and the coating face. The surface coating is flush with the visible tab 13 and covers the boundary area between the channel body 10 and the casting mortar. In one embodiment, the surface coating can comprise, for example, an epoxy-based coating. Alternatively, other casting materials and surface coatings are also possible.

Fig. 4 and 5 show the free axial end of the channel body 10. Fig. 4 shows the first axial end 20. The first axial end 20 has a lower projection 22.

In the mounted position, the lower projection 22 has a contact surface 25 which points at least in sections upwards. The lower projection 24 has a contour which substantially corresponds to the surface contour of the channel body 10. The contact surface 25 therefore has a step in the region of the side wall 12 in the region of the bearing surface 16 and a continuous surface in the region of the channel floor 11. The contact surface 25 has an inclination which tapers the axial end of the lower projection.

Figure 5 shows the second axial end 21 of the channel body 10. The second axial end 21 has an upper projection 23. The upper projection 23 has a contact surface 25 on the lower side in the mounted state. The lower contact surface 25 has an inclination which corresponds to the inclination of the contact surface 25 of the first axial end 20, respectively. In other words, the contour of the upper projection 23 is adapted to the contour of the lower projection 22. The first axial end 20 and the second axial end 21 are designed to provide the two channel bodies 10 with a form fit on one another.

Figure 6 shows substantially one embodiment of a channel body 10 according to the above figures. The channel body in fig. 6 has an opening. The openings are connection openings in order to provide drains, for example, on the channel body 10. The opening is circular and is arranged in the region of the second axial end 21. Other locations for providing the opening are possible.

Fig. 7 to 10 show an end wall 26 for the channel body 10 according to fig. 1 to 6. The end wall 26 in fig. 7 and 8 is configured for disposition on the first axial end 20 of the channel body 10. For this purpose, the end wall 26 has a profile corresponding to the second axial end 21. The end wall 26 comprises a contact surface 25 which corresponds to the contact surface 25 of the second axial end of the channel body 10 and which in the mounted state is directed at least in sections downwards. The contact surface 25 is provided on a projection surface corresponding to the upper projection 23.

The end wall 26 in fig. 9 and 10 is configured for disposition on the second axial end 21 of the channel body 10. For this purpose, the end wall 26 has a lower projection with an at least partially upwardly directed contact surface 25, which corresponds to the contact surface 25 of the first axial end 20. The contact surface 25 is provided on a projection surface corresponding to the lower projection 22.

The end walls 26 according to fig. 7 to 10 each have a visible web 13, to which the cover layer 14 adjoins and is set back by a step 15. In the mounted state, the cladding face 14 and the visible tab 13 of the end wall 26 are flush with the cladding face 14 and the visible tab 13 of the channel body 10.

Fig. 11 and 12 show method steps for laying the channel body 10. More precisely, two channel bodies 10 are connected to each other. The channel body 10 is provided 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.

In fig. 13 and 14, the two channel bodies 10 are arranged on one another in a form-fitting manner. The lower projection 22 of the first axial end 20 is longer than the upper projection 23 of the second axial end 21. The upper projection 23 rests on the lower projection 22 in the mounted state. The lower projection 22 abuts on the second axial end 21. The upper projection 23 is not butted against the first axial end 20.

Thereby, a joint 24 is formed between the upper protruding portion 23 and the first axial end 20. The engagement portion 24 is delimited by the surface of the lower projection 22, the end side of the first axial end 20 and the end side of the upper projection 23 of the second axial end 21. The engagement section 24 opens upward and inward in the installed position and opens outward in the region of the visible web 13 and the cover layer 14 up to the contact surface 25 of the lower projection 22.

Fig. 15 shows the device according to fig. 11 to 14, wherein the joint 24 is filled with adhesive. In fig. 15, two channel bodies 10 are connected to one another in a form-fitting and material-fitting manner. The adhesive layer is flush with the surface of the channel body 10.

Fig. 16 and 17 show end walls 26, respectively, provided on the channel body 10. Fig. 16 shows the end wall 26 provided at the first axial end 20, and fig. 17 shows the end wall 26 provided 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.

Fig. 18 shows two interconnected channel bodies 10, which are each provided with an end wall 26 at their open axial ends. A grate 17 is provided in the channel body. The grate 17 is made of plastic and rests on the support surface 16.

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

The combination of polymer concrete with the grate 17 made of plastic makes it possible to produce the drain channel without any metal parts. The drain channel is thus corrosion resistant.

In the installed state, the channel body 10 is embedded in a casting material, preferably a casting mortar, up to the cladding surface 14. The surface coating is disposed on the casting mortar. The surface coating extends over the casting mortar and over the coating surface 14 and is flush with the visible tab 13. The surface coating covers the boundary area between the casting mortar and the channel body 10. Thereby reducing the likelihood of: fluid can enter between the mortar and the channel body 10. This means that crack formation and cracking of the surface coating is prevented. By means of the cover layer 14, a sealing plane is formed which improves the tightness of the connection between the channel body 10 and the casting mortar.

The slope of the step 15, which recedes the cover layer 14 from the visible web 13, and the rounded transition to the cover layer 14 allow a simple application of the surface coating to the visible web 13, with a reduction in the formation of cavities in the region of the step 15, which could lead to cracking of the surface coating.

These two

axial ends

20, 21 form a connecting device. The two channel bodies 10 can be simply connected to one another by the axial ends 20, 21 engaging one another. The second axial end 21 can be laid onto the first axial end 20 from above. The inclination of the contact surface 25 additionally simplifies the arrangement from above. Due to the inclined, corresponding contact surface 25, the channel body 10 slides into position and can thus be positioned simply.

The upper projection 23 is shorter in the longitudinal direction than the lower projection 22. The two

axial ends

20, 21 are designed such that they engage into one another in the assembled or partially assembled state. The engaging portion 24 is constituted by the shorter upper protruding portion 23. The joint 24 is used to receive an adhesive for connecting the two channel bodies 10. The adhesive material connects the two channel bodies 10 in a fitting manner and additionally seals the connection.

In the mounted state of the channel body 10, the free space of the anchoring recess 18 is filled with a casting material, for example a casting mortar. In the installed state, the channel body 10 is connected to the surrounding casting mortar by means of the anchoring recess 18 in a form-fitting manner. The anchoring recesses 18 thus improve the retention of the channel body 10 in the casting mortar and resist movements of the channel body in the casting mortar due to dynamic and/or static loads. Thereby reducing crack formation in the surface coating.

The stiffening element 19 improves the structural stability of the channel body 10. Furthermore, the reinforcing element 19 delimits the anchoring recess 18 in the axial direction. Thereby, in the mounted state, the movement of the channel body 10 in the longitudinal direction is reduced and crack formation in the surface coating is reduced.

The end wall 26 encloses the channel body 10 in the axial direction in a fluid-tight manner. The design of the end wall 26 enables the connection to the channel body 10 according to the above-described connection device. The end wall 26 can be arranged on the channel body 10 from above in a form-fitting manner and subsequently bonded by the joint 24.

The above-described juxtaposed aspects of the invention and embodiments thereof contribute to meeting the requirements set forth for a traffic area, in particular a drainage channel for a parking platform, parking garage and/or parking building, which has a surface covering as the uppermost paved surface. The features of the juxtaposed aspects and embodiments thereof particularly improve the sealing properties or long-term retention of the sealing properties of the channel body or drain channel.
