Description

The invention relates to a drainage device for a structural structure according to claim 1 and a kit comprising at least one drainage device according to claim 15.

From the DE 20 2019 105 054 U1 Drainage devices are known for on-site installation on floor-to-ceiling windows and doors of false ceilings, which enable floor-level access to the building. These drainage devices are designed with a gutter covered with a grid. The disadvantage of these drainage devices, however, is that they have to be placed directly on the wall in front of the wall opening, which forms the building entrance. However, especially for houses that are supposed to meet the passive house standard, it is necessary to adequately insulate external walls, especially those that are in direct contact with the ground. However, the materials used for this insulation are generally not load-bearing, in particular they cannot be walked on. The drainage devices known in the prior art are therefore not suitable for use in a passive house because of the arrangement of the Drainage device can create a so-called thermal bridge directly on the house wall. The thermal bridge conducts heat from the room that is closed off by the outer wall, so that the thermal insulation is not sufficient for the passive house standard. Another problem with thermal bridging is that the wall is cooler than the air in the room. This causes the moisture in the room air to condense on the cooler wall and promote the formation of mold.

Apart from that, there are also elements on the ground in other structural structures which are not resilient and which need to be bridged with suitable measures while drainage must be ensured. For example, in the case of concrete balconies, a non-load-bearing seal is installed on the wall at the transitions between the module parts and the building. Any water that accumulates must still be diverted away from the building. The same problem arises for sealing as with non-load-bearing insulation.

There is therefore a great need for a drainage device that does not promote or, in particular, prevents thermal bridges on structural structures and enables floor-level access to corresponding wall openings in a simple and reliable manner. At the same time, the drainage device should be able to bridge non-load-bearing elements, particularly elements arranged on the floor of structural structures. When installed, the drainage device should ensure sufficient and continuous liquid drainage and sealing of the structural structure from the environment. In addition, the drainage device should be inexpensive to produce and durable, as well as simple, quick, reliable, individual and adaptable to the local conditions as required. Another focus is on the simple and quick installation of the drainage device.

The invention has set itself the task of providing such a drainage device and at the same time overcoming the disadvantages mentioned above.

This task is achieved in a surprisingly simple but effective manner by a drainage device according to the teaching of independent main claim 1 and by a kit comprising at least one drainage device according to the teaching of claim 15.

According to the invention, a drainage device for a structural structure is proposed, which comprises a lower part, at least one cover element and at least one cross strut, the cover element being arranged on the cross strut, and the lower part comprising a first wall on the longitudinal side. The drainage device is characterized in that the lower part comprises a first surface and a second surface offset in height from the first surface and in that the cross strut comprises a main body spanning the first surface and an arm spanning the second surface, the first wall being between the first surface and the second surface is arranged and wherein the main body is connected to the first wall in a force-transmitting manner.

In the context of the invention, it has been recognized that in order to enable the arrangement of the insulating material on the structural structure and to prevent a thermal bridge, the liquid-carrying part of the drainage device must be spaced from the structural structure. It must be ensured that the liquid that the drainage device is intended to keep away from and/or drain away from the building structure can still be carried away reliably and safely. This is achieved in that the drainage device has a first surface over which the water is ultimately and finally directed away from the building structure. In order to create a sufficient distance between this first surface and the structural structure, in which non-loadable elements, for example Insulating material or seals can be arranged, the drainage device comprises a second surface which is offset in height from the first surface to create space. The second surface extends completely to the structural structure and directs the liquid that accumulates directly on the structural structure to the first surface. The liquid is directed to the first surface by gravity via the height adjustment. In order to protect the non-loadable element from the action of the water to be drained away, a first wall is arranged between the first surface and the second surface. Furthermore, it has been recognized within the scope of the invention that, due to the flat design, the second surface is not suitable for dissipating forces that act on the drainage device in a way that ensures that the non-loadable element is not loaded. However, loading the non-loadable element must be avoided at all costs, as the non-loadable element is not load-bearing. Therefore, the drainage device comprises a cross strut with an arm spanning the second surface. The arm is designed in such a way that the arm transfers forces that act vertically on it to the first wall. In this way, the second surface is not loaded, so that the non-loadable element underneath remains unloaded. The basic idea of the invention is to create a space for the non-loadable element via the height-offset second surface and to keep it free of acting forces via the arm of the cross strut.

According to the invention, the drainage device comprises a lower part which serves as a base component for the drainage device and via which the liquid is primarily directed away from the structural structure according to the invention in order to fulfill the drainage effect. For this purpose, the lower part seals the structural structure from the surroundings, in particular from the subsurface of the structural structure. The lower part includes a first surface and a second surface offset in height from the first surface. In this way, the entire width of the cavity in which the non-loadable Element is arranged. The surfaces are oriented in such a way that the cavity extends on site. In order for the sealing of the structural structure according to the invention to be achieved, the first and second surfaces must be connected by means of a first wall arranged between them and running along the longitudinal side of the structural structure. The sealing is preferably achieved in that the lower part, in particular the first surface, the second surface and the first wall, is made of a water-impermeable material. In order to drain the liquid according to the invention, the first surface and the second surface must be designed to be smooth and flat. The first wall is preferably also designed to be smooth. However, due to the vertical orientation of the first wall, this is not absolutely necessary. However, a smooth design encourages the liquid to drain away without leaving any residue. The lower part is preferably made of a metal, in particular iron, zinc, aluminum and/or copper, of an alloy, of a steel, in particular stainless steel, even more preferably chrome-nickel steel, of a plastic, in particular a polymer, of concrete, made from a rock and/or a mixture thereof. These materials are sufficiently smooth and at the same time, with the appropriate orientation and thickness, load-bearing, durable, dense, inexpensive to produce and malleable.

According to the invention, the drainage device comprises at least one cover element with which the top of the drainage device is closed. The drainage device preferably comprises at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 cover elements of identical or different design. The arrangement and/or design of the cover element must ensure that the liquid to be transported away from the structural structure can reach the drainage device. The cover element thus forms the top of the drainage device and is the part of the drainage device which, when used according to the invention, can be resilient, in particular walked on and/or passable, is. For this purpose, the cover element is designed in such a way that it can dissipate forces acting on it vertically. This can be achieved in particular, but by no means exclusively, through the design and/or selection of materials. Suitable materials and suitable designs are set out elsewhere. The forces acting vertically on the cover element must then be transferred to the subsurface. For the reasons stated above, the second surface must remain as free of load as possible.

In order to achieve this, the drainage device comprises at least one cross strut. The drainage device preferably comprises at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 or 20 cross struts of identical or different design. The crossbar is essentially aligned transversely to the structural structure and transversely to the first wall. Furthermore, the cross strut has a main body spanning the first surface and an arm spanning the second surface. The cover element lies flat on the cross strut, so that a cavity is created between the cover element and the first surface or cover element and the second surface, through which the liquid is drained, as is generally known in the prior art. The forces that act vertically on the cover element are passed on to the cross strut. In order to ensure the transmission of force from the crossbar to the ground, the main body is connected to the first wall in a force-transmitting manner. It is essential to the invention that the force is applied in the plane of the first wall and not along the normal of the plane, as would be the case with the second surface if a vertical force were to act on the second surface. In this loading direction, the manufacturing materials of the lower part are significantly more resilient. The force-transmitting connection makes it possible to divert forces acting vertically on the cover element to the subsurface via the cross strut and the first wall. Since the arm of the cross brace passes through the cover element absorbs derived forces, the second surface remains largely unloaded, even if the vertically acting forces occur in the area of the second surface.

The term “structural structure” refers to a structure that is created by a structural measure. It is therefore conceivable that the structural structure, in particular, but by no means exclusively, is a building, in particular a wall, a wall opening, a door, a window, a gate, a roof and/or a balcony, a street, a path, a Terrace, paving, a combination thereof and/or parts thereof.

The term “on-site” refers to an arrangement arranged on the building structure and/or facing the building structure.

The term "longitudinal" refers to the essentially parallel alignment of the first wall to a base line of the building structure, neglecting projecting or recessed elements of the building structure. In particular, it is also conceivable that the design of the wall is adapted to the course of the base line of the building structure.

The term “sealing” describes a degree of tightness to a liquid between two areas. The liquid is preferably water, in particular rainwater, surface water and/or groundwater. It is understandable that the term tightness is a relative term, as there are no absolutely tight drainage devices and/or parts thereof. In the context of the invention, sealing or tightness is therefore to be understood as meaning that this always refers to previously determined and/or predetermined framework conditions, with the drainage device understandably due to the ingress of liquid from an unintended direction, for example splash water, or in a direction not intended The intended amount, for example in the event of a flood, cannot guarantee any or only a limited seal.

The invention makes it possible to provide a drainage device which enables the prevention of thermal bridges. At corresponding wall openings, it is also possible to create floor-level access through the flat top of the cover element. The drainage device offers a sealing of the building structure from the environment that meets the requirements and is inexpensive to produce and easy and quick to install.

Advantageous developments of the invention, which can be implemented individually or in combination, are presented in the subclaims.

It is advantageously conceivable that the cross strut comprises a first fastening means and the first wall and/or the second surface comprises at least one first holding means, wherein the first holding means and the first fastening means are designed for a positive and/or non-positive connection. In the context of the invention, it has been recognized that the connection by means of a first holding means and a first fastening means is particularly stable and durable, while a subsequent release of the connection for repair, cleaning or maintenance work is possible. The configuration of the first holding means and that of the first fastening means is particularly preferably a hook, a slide, a pawl, an edge, a spring, a recess, a groove, an eyelet, a projection, a recess, a knob, a trap, a stop and/or a combination thereof. Possible combinations with the associated advantages are known to those skilled in the art. It is also conceivable that these are connected using a screw, rivet, hole and/or releasable adhesive connection known to those skilled in the art. It is conceivable that the first holding means is arranged on the first or on the first wall, in or on the second surface or in or on the first wall and in or on the second surface. In the context of the invention, it has been recognized that the first holding means only has the task of securing the cross strut in the correct position can take over position. The power transmission, in particular the dissipation of vertically acting forces, continues to take place by means of a force-transmitting connection between the cross strut and the first wall. For example, it is conceivable that the main body has a protruding edge, which is inserted in a form-fitting manner into a recess in the second surface, so that the main body rests on the wall and cannot be moved. In this embodiment, the first holding means is arranged in the second surface, but the force is still transmitted via the first wall. Furthermore, it is conceivable that the first wall and/or the second surface has at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 or 50 has the same or differently designed first holding means. Furthermore, it is conceivable that the cross strut has at least 2, 3, 4, 5, 6, 7, 8, 9 or 10 first fastening means of the same or different design. If the first wall and/or the second surface has several holding means, in particular if more holding means are provided as cross struts, it is possible to arrange a correspondingly higher number of cross struts on the first wall and/or the second surface and/or the placement of the Cross braces must be selected in several places according to the requirements. If more than one cross brace is provided, the drainage device becomes more stable overall and can therefore be subjected to a greater load. It is also possible to place several cover elements safely and stably, in particular without tipping, on the drainage device. Allowing a choice in the placement of the crossbar or crossbars offers the advantage that the drainage device is easily and simply adaptable to on-site conditions. It is therefore conceivable that the conditions on site require a shorter width of the drainage device than was intended for the standard production of the lower part. The crossbars can be placed anywhere for this purpose, and the part of the drainage device that is not required can be removed or closed using suitable structural measures. Particularly preferably, the first holding means is designed as two parallel, slot-shaped recesses made in the first wall and in the second surface, which are arranged transversely to the first wall, and the first fastening means is designed as two hooks arranged at the transition between the main body and the arm . The design of the crossbar with 2 to 10 first fastening means of the same or different design enables a better and/or more secure connection of the crossbar to the first wall and/or the second surface.

The term “width of the drainage device” refers to the dimension of the drainage device in the direction that runs parallel to the structural structure when the drainage device is installed as intended.

In a further development of the invention, it is conceivable that the lower part comprises a third surface opposite the second surface and offset in height from the first surface, with a second wall being arranged on the longitudinal side between the first surface and the third surface. In the context of the invention, it has been recognized that, in order to improve the sealing, it is advantageous not only to hold and direct the liquid away from the structural structure, but also to divert it in a targeted manner. By arranging the second wall, the first wall, the first surface and the second wall form a channel in which the liquid can be drained away in a targeted manner. In this way, liquid that occurs on the side of the drainage device opposite the structural structure can also be drained away from the drainage device before the liquid penetrates to the structural structure. If the cross strut also extends into the area of the third surface, the cover element can be arranged in the area above the third surface in addition to forming a closed configuration of the top. There adjacent to the second Wall and below the third surface, as a rule, no non-loadable element has to and / or should be arranged, it is conceivable that the third surface is smaller, in particular narrower, and / or is offset in height from the first surface by a different height than the second surface .

In a further embodiment, it is conceivable that the main body is connected to the second wall in a force-transmitting manner. In this way, two support points are created for the crossbar, whereby it rests particularly stably on the drainage device and the first wall is partially relieved of the load. Furthermore, it is not possible to twist the crossbar in the plane that is perpendicular to the first wall. Therefore, in this embodiment, the drainage device can be loaded with a greater vertically acting force, and/or the lower part can be made thinner overall, thereby saving material.

It is preferably conceivable that the cross strut comprises a second fastening means and the second wall and/or the third surface comprise at least one second holding means, wherein the second holding means and the second fastening means are designed for a positive and/or non-positive connection. In principle, the second fastening means and the second holding means can take all the forms described in connection with the first fastening means and the first holding means. Particularly preferably, the second fastening means and the second holding means are identical and designed to be mirror-symmetrical to the first fastening means and the first holding means. Even more preferably, the second wall and/or the third surface comprises 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 , 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45 , 46, 47, 48, 49 or 50 second holding means of the same or different design. This results in the advantages described elsewhere.

Furthermore, it is conceivable that the first surface, the second surface and/or the third surface are rotated relative to the horizontal plane by at least 1° and/or by a maximum of 25°. In the context of the invention, it has been recognized that liquid can also be drained off due to the smooth design of the lower part if a surface is arranged essentially horizontally. A slight twist relative to the horizontal plane allows for a slight gradient, which allows the water to be drained away even better and in a more controlled manner. However, if this twist is too great, the drainage becomes uncontrolled and the water can splash out of the drainage device. In practice it has been shown that a rotation of a maximum of 25 degrees promotes the drainage of water without it being drained away in an uncontrolled manner. However, especially for the second surface, it should also be noted that twisting is always accompanied by a reduction in insulation, as the space for insulation is reduced. Particularly preferred are the first surface, the second surface and/or the third surface by at least 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11° relative to the horizontal plane , 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23° or 24° twisted. Even more preferred are the first surface, the second surface and/or the third surface with respect to the horizontal plane by a maximum of 24°, 23°, 22°, 21°, 20°, 19°, 18°, 17°, 16°, 15 °, 14°, 13°, 12°, 11°, 10°, 9°, 8°, 7°, 6°, 5°, 4°, 3° or 2° twisted. It is conceivable that the first surface, the second surface and/or the third surface have the same and/or different twists. It is also conceivable that the first wall, the second wall and/or the boundary are rotated relative to the vertical plane by at least 1° and/or by a maximum of 25°. The rotation of the first wall, the second wall and/or the boundary is preferably at least 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23° or 24° from the vertical plane. Even more preferred are the first wall, the second wall and/or the boundary relative to the vertical plane by a maximum of 24°, 23°, 22°, 21°, 20°, 19°, 18°, 17°, 16°, 15°, 14°, 13°, 12°, 11°, 10°, 9°, 8°, 7°, 6°, 5°, 4°, 3° or 2° twisted. It is conceivable that the first wall, the second wall and/or the boundary have the same and/or different twists.

It is also conceivable that the first wall has a perforation adjoining the second surface and/or the second wall has a perforation adjoining the third surface. The perforation can be used to direct liquid away from the on-site structure that is to be protected by the drainage device. The liquid can be, for example, rising groundwater. Surface water that occurs on the side opposite the structural structure can also be introduced into the channel, even if, due to the design, it does not flow exclusively on the surface, but rather within the surface. This is the case, for example, with a layer of gravel. At the same time, the perforation can prevent unwanted parts such as rubbish, stones, gravel, sticks or other foreign bodies from getting into the drainage device. This reliably prevents the drainage device from clogging. Should the drainage device still become clogged, the perforation can also serve as an emergency overflow device. It is basically arbitrary how the perforation is designed; it is preferably formed by elongated recesses. Elongated recesses can be made easily and simply in the first wall or in the second wall and are large enough to allow liquid to pass through, but to prevent unwanted parts from being stored.

It is also conceivable that the lower part has an outlet arranged in the first surface. By means of the outlet arranged in the first surface, the liquid collected by the drainage device can be drained into a drainage system. In this way, the final drainage of the liquid away from the building structure is made possible. The outlet with a grid is particularly preferred covered so that unwanted parts cannot get from the drainage device into the drainage system.

In yet another development, it is conceivable that the lower part comprises at least one boundary arranged on the longitudinal side. The limitation prevents the cover element from slipping transversely to the structural structure and/or enables the resulting liquid to be introduced into the drainage device in a controlled manner. Depending on how the cover element and/or the structural structure are designed, a one-sided limitation may be sufficient to prevent slipping. The lower part preferably comprises two boundaries arranged on the longitudinal side. In this way, the cover element is encompassed on both sides and cannot slip regardless of the structural structure and/or its design. In a further development, it is conceivable that the limitation arranged on the longitudinal side can be mounted on site in a force-transmitting manner. In this way, rotation of the drainage device around the first wall is prevented if the drainage device is loaded solely in the area of the first surface. Here, a torque acts on the first wall via the cross strut, which causes the drainage device to tilt in the direction of the building structure. Since the torque, especially when the first wall is vertical according to the invention, is very low and therefore the force acting on the first surface is very small, there is no risk of bending of the material forming the first surface, unlike in the case of a direct load.

Furthermore, it is conceivable that the cross strut is a solid wall support, in particular a sheet metal edge profile or a continuously cast profile and / or an I, P, T, H, TH, Z, U or an L profile, a hollow profile support, in particular with a rectangular profile or a square profile, a hollow box girder and/or a solid body. The profile of the crossbar is preferably a triangle, a rectangle, a hexagon, in particular a regular hexagon or a polygon. Solid wall beams, hollow profile beams and Hollow box girders are characterized by their light weight and the low amount of material used in production, while a solid body is particularly stable. It is particularly conceivable that the main body is designed differently than the arm. Particularly preferably, the main body is a hollow profile body with a rectangular profile, while the arm is designed as a solid wall support with a U-profile.

Furthermore, it is conceivable that the drainage device comprises an insulating element that can be arranged on site below the second surface. If the drainage device already includes an adapted insulating element, the insulating material does not have to be laboriously cut to size on site. This prevents incorrect assembly and/or incorrect cutting on site.

It is also conceivable that the drainage device comprises at least one support. As described elsewhere, if the covering element is subjected to a limited area of load, a torque can occur around the first wall in the area above the second surface, which can cause the drainage device to tip. To prevent this, a support can be installed. The support preferably comprises an L-shaped angle. Particularly preferably, the support can be installed on site. The support, which can be installed on site, engages the edge of the second surface, in particular the first boundary, which faces the structural structure. Additionally or alternatively, at least one support can be arranged facing away from the customer, in particular the support arranged facing away from the customer can engage the second wall, in particular the perforation of the second wall, the third surface and/or the second boundary. The support, which is arranged facing away from the customer, is connected to the surrounding structure facing away from the drainage device in a suitable manner in a force-transmitting manner. The support counteracts the torque and effectively prevents the drainage device from tipping.

In a further development of the invention, it is conceivable that the lower part comprises at least one side end and/or at least one connecting element. The side closure allows the drainage device to be closed from the side. In this way, the liquid cannot escape from the drainage device at this point. The side end can then be arranged on one of the edges of the first wall and/or the second wall transversely to the structural structure, but it is also conceivable that the side end is offset from the edge on the first wall and/or the drainage device for better adaptability of the drainage device second wall and arranged transversely to the structural structure so as to create a drainage device with a shorter width. A connecting element enables connection to a second, differently or identically designed drainage device in order to form a drainage device system of any length. In one embodiment, it is conceivable that the first wall and/or the second wall comprises at least one structure for receiving the connecting element and/or the side closure, such as the first holding means, the second holding means and/or the perforation. This structure is preferably a vertically oriented elongated slot, the elongated slot having a leg on the upper edge of the wall and/or the first surface. The side connection and/or the connecting element has a hook in the upper region of one or both side edges, so that the side connection and/or the connecting element can easily be inserted into the first wall and/or the second wall in a positive and/or non-positive manner. This enables quick and easy assembly. If the first and/or the second wall has more than one structure on one side, the spacing from the edge of the first wall can be freely selected and the drainage device can be easily adapted to the conditions on site, as described elsewhere.

It is also conceivable that the arm has a length of at least 3 cm and a maximum of 50 cm. Basically, it is arbitrary how long the arm is, but a longer arm means more space for arranging non-loadable elements. In this way, a better insulating effect can be achieved in particular, since the insulation that can be arranged below the second surface can be made thicker. At the same time, a longer arm also means a greater torque, which acts on the first wall when the arm is loaded. A length of 3 cm to 50 cm provides a sufficiently large margin for the necessary thickness of the insulating material, which depends on the structural structure and the prevailing climate, and for limiting the maximum torque acting on the first wall. The arm preferably has a length of at least 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17cm, 18cm, 19cm, 20cm, 21cm, 22cm, 23cm, 24cm, 25cm, 26cm, 27cm, 28cm, 29cm, 30cm, 31cm, 32cm, 33cm , 34 cm, 35 cm, 36 cm, 37 cm, 38 cm, 39 cm, 40 cm, 41 cm, 42 cm, 43 cm, 44 cm, 45 cm, 46 cm, 47 cm, 48 cm or 49 cm. The arm particularly preferably has a length of at most 49 cm, 48 cm, 47 cm, 46 cm, 45 cm, 44 cm, 43 cm, 42 cm, 41 cm, 40 cm, 39 cm, 38 cm, 37 cm, 36 cm , 35cm, 34cm, 33cm, 32cm, 31cm, 30cm, 29cm, 28cm, 27cm, 26cm, 25cm, 24cm, 23cm, 22cm, 21cm, 20cm, 19 cm, 18 cm, 17 cm, 16 cm, 15 cm, 14 cm, 13 cm, 12 cm, 11 cm, 10 cm, 9 cm, 8 cm, 7 cm, 6 cm, 5 cm or 4 cm. The second surface is designed to correspond to the length of the arm.

In a further development, it is conceivable that the cover element is made of a metal, in particular iron, zinc, aluminum and/or copper, of an alloy, of a steel, in particular stainless steel, more preferably chrome-nickel steel, of a plastic, in particular a polymer, concrete, rock and/or a mixture thereof. These materials are characterized by their hardness and abrasion resistance, so that they are durable and can withstand the loads that occur according to the invention.

The term "mixture" refers to a material that is composed of two or more components. It is also conceivable that a cover element is formed from a metal and a plastic, in that part of the cover element is made of metal and another part of the cover element is made of a plastic.

Furthermore, it is conceivable that the cover element has a perforation. Liquid can flow from the top of the cover element into the drainage device via the perforation. The cover element particularly preferably comprises a grid, a grate and/or a sieve.

The definitions and/or explanations of the above terms are deemed to apply to all aspects described in this description below, unless otherwise stated.

According to the invention, a kit for producing a drainage system is also proposed, the kit comprising at least one drainage device according to one of claims 1 to 14 and assembly instructions.

In the context of the invention, it has been recognized that the drainage device according to the invention is particularly simple and easy to assemble and adaptable to the conditions on site. It is therefore advantageous to provide a drainage device according to the invention together with assembly instructions which serve to explain and instruct the user or the installer of the drainage device. The assembly instructions contain, in particular, warnings and other information that may be required by law, as well as technical specifications and the aforementioned explanations and instructions.

Fig. 1 shows a perspective view of a drainage device 10 according to the invention. In this embodiment, the drainage device 10 comprises six cover elements 20 made of nickel-chromium steel, which include a grid. The cover elements 20 rest on six cross struts 30, with only one cross strut 30 in the Fig. 1 is recognizable. A force which acts on the cover elements 20, for example due to the appearance of a person, is passed on to the cross struts 30. The cross struts 30 are connected to a lower part 50 in a force-transmitting manner. This means that the force which acts on the cover elements 20 is passed on to the lower part 50 via the cross struts 30. The force is ultimately transferred from the lower part 50 into the ground. The drainage device 10 further comprises an insulating element 40. On the side, the drainage device 10 is closed off with two side closures 60, in which Fig. 1 only one of the two side ends 60 is visible.

Fig. 2 shows an exploded view of the drainage device 10 according to the invention Fig. 2 the six cover elements 20 are clearly visible and distinguishable from one another. The two middle cover elements 20 are designed differently than the four side cover elements 20. The cover elements 20 have a perforation 21 on their top that forms the grid. It can also be clearly seen that the drainage device 10 has a total of six cross struts 30. Two cover elements 20 lie transversely on two cross struts 30. It can also be seen that the insulating element 40 is adapted to the drainage device 10 in such a way that it essentially fits into the lower part 50 in a form-fitting manner. Both side ends 60 can also be seen, which close off the lower part 50 laterally. On the underside of the drainage device 10, a connecting pipe 63 is connected to one in the Fig. 2 outlet, not shown, mounted in the lower part 50. Furthermore, the drainage device 10 includes a support 70, which supports the drainage device 10 on site in such a way that it does not tip over under a one-sided load.

Fig. 3 shows a cross strut 30 according to the invention. The cross strut 30 is formed by a main body 31 and an arm 32. The main body 31 is formed by a hollow profile support with a rectangular cross section, the arm 32 by a solid wall support with a U-profile. At the transition between the main body 31 and the arm 32, the cross strut 30 includes a first fastening means 33. The first fastening means 33 includes two hooks. On the main body 31, opposite the first fastening means 33, the cross strut 30 comprises a second fastening means 34, which is also formed by two hooks.

Fig. 4 shows a lower part 50 according to the invention. The lower part 50 comprises a first surface 51, which is arranged on the bottom side. According to the invention, a first wall 54 stands perpendicular to the first surface 51 on site. A second surface 52 adjoins the first wall 54 at the upper edge, offset in height from the first surface 51. Below the second surface 52 and to the side of the first wall 54, the in the Fig. 4 Insulation element, not shown, arranged (see Fig. 1 ). A first boundary 56 is arranged on the longitudinal side of an edge of the second surface 52 and opposite the first wall 54. The first boundary 56 can be connected to the structural structure to prevent the drainage device 10 from tipping. A second wall 55 is arranged on the first surface 51, opposite the first wall 54. A third surface 53 is arranged at a height offset from the first surface 51 and adjacent to the second wall 55. Opposite the second wall 55, a second boundary 56 adjoins an edge of the third surface 53. The limitations 56 serve to to prevent the cover elements 20 (not shown) from slipping transversely to the structural structure (see Fig. 1 ). At the same time, the boundaries 56 enable the resulting liquid to be introduced in a controlled manner. The cross struts, not shown, span the first surface 51 with the main body 31 and the second surface 52 with the arm 32 (see Fig. 1 and Fig. 3 ). The forces that act vertically on the cross strut are transferred directly to the first wall 54 and the second wall 55. As a result, the second surface 52 remains stress-free. Perforations 57 are made in the first wall 54 and the second wall 55. Liquid can get into the interior of the drainage device 10 via these perforations 57. In the event of a blockage, the perforation 57 can also serve as an emergency overflow device and drain any liquid that accumulates from the drainage device 10. For this purpose, the insulating element, not shown, has a corresponding recess at the point adjacent to the perforation 57 of the first wall 54 (see Fig. 2 ). Furthermore, first holding means 58 are arranged on the top of the first wall 54 and in the second surface 52. Mirror-symmetrically designed second holding means 56 are arranged in the second wall 55 on the upper edge and in the third surface 53. For the sake of clarity, only a first holding means 58 and a second holding means 59 are shown. An outlet 62 is arranged in the first surface 51, which is closed with a grid. The first wall 54 and the second wall 55 each have several structures 61.

Fig. 5 shows an enlarged section of the lower part 50 according to the invention. In Fig. 5 The perforation 57 can be seen particularly well, which is made in the first wall 54 on the top side adjacent to the first surface 52. One of the first holding means 58 can also be seen. This is designed as two slot-shaped recesses. Next is in Fig. 5 a structure 61 for receiving the in the Fig. 5 Side end 60, not shown, visible (see Fig. 1 ). The first wall 54 or the first surface 52 has several structures 61, to enable the length of the drainage device 10 to be easily adjusted. The first structure is designed as an L-shaped recess, so that the side end 60 fits in positively and/or non-positively.
