[0001] REHAU Industries SE & Co. KG Rehau, November 7, 2024
[0002] Int. sign: 24.033 / 1 dr.schie-ik
[0003] Trench half-element
[0004] The invention relates to a trench element comprising a base grid and at least two columns connected to the base grid and extending approximately perpendicularly from the base grid, as well as at least one settling arrangement. The invention also relates to a trench component and a receiving, storage, or infiltration device.
[0005] Infiltration trenches, used for collecting, storing, or infiltrating fluids, especially rainwater, are assembled from individual elements. Specifically, trench systems are used that feature a base grid from which columns rise approximately vertically. Connecting devices are used to join the trench system at the column tips, i.e., at the column ends opposite the base grid. The columns can either be loosely stacked on top of each other or joined using snap-fit connections.
[0006] In order to arrange such trench systems in a space-saving manner during production, storage and transport, the columns are hollow, so that such trench systems can be stacked by inserting the columns of a neighboring trench system into the hollow space of the columns of a trench system.
[0007] The infiltration trench system, as part of a collection, storage, or infiltration device, must withstand certain forces. These forces arise, on the one hand, from the underground installation of such a device. They are subjected to earth pressure and, if applicable, the hydrostatic pressure of the rainwater collected within them. On the other hand, they must also bear traffic loads from the roads located above. REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie
[0008] The columns of the trench system serve to transmit the forces in the vertical direction. These must be designed according to the mechanical and static requirements.
[0009] When designing the columns for a trench system with regard to the requirement for force transmission, problems repeatedly arise, especially if these types of columns are also intended to allow for the possibility of stacking the trench systems.
[0010] EP 0943737 discloses a trench system, in particular an irrigation and / or drainage box, with a perforated base and perforated side walls integrally connected to the base, wherein the box is open on the side opposite the base, and the open side of the box is designed such that two identical boxes can be placed with their open sides facing each other and connected to each other without the need for any further accessories, wherein the side walls are substantially perpendicular to the base, the box has columns extending substantially perpendicularly from the base to the open side, and at least some of the columns on the open side of the box are provided with first connecting parts and other columns on the open side of the box are provided with second connecting parts, such that,When two identical boxes according to the invention are placed with their open sides facing each other, the first connecting parts of one of the two identical boxes are able to interact with the second connecting parts of the other of the two identical boxes to form a connection between the two identical boxes.
[0011] A disadvantage of the current state of the art is that, for intended use, so-called side walls with perforations must always be provided, which on the one hand drive up the costs of manufacturing such trench systems, and on the other hand, due to their large-volume construction, they require more space, especially during transport and storage, and therefore also cause increased costs for transport and storage.
[0012] It is an object of the present invention to overcome the disadvantages of the prior art and to further develop a trench half-element of the type mentioned above in such a way that it can be manufactured economically, cost-effectively and sustainably, has a simple and stable structure and can be used without tools or additional attachments. A further object of the present invention is to provide a trench construction element. REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie
[0013] It is also an object of the invention to specify a receiving, storage or infiltration device which is constructed from trench elements.
[0014] The first problem is solved according to claim 1. Further advantageous embodiments are disclosed in the dependent claims relating thereto.
[0015] It has surprisingly turned out that a trench half-element, comprising a base grid and at least two columns connected to the base grid and extending approximately perpendicularly from the base grid, as well as at least one settling arrangement, is characterized in that at least two columns are connected to each other via at least one settling arrangement, that the settling arrangement has at least one settling section and at least one outlet section, that the settling section is connected to the base grid, that a first outlet section and a second outlet section parallel and opposite each other are arranged on the settling section, that at least one connecting element and at least one stiffening element are arranged at the free ends of at least one outlet section, and that the settling arrangement has at least one infiltration section.This makes a half-element of the infiltration trench available that can be manufactured cost-effectively, economically, and sustainably. Furthermore, it was determined that this half-element can be installed easily and safely without tools or additional components.
[0016] A key advantage of the infiltration trench half-element is that the settling section is liquid-tightly connected to the base grid. When used as intended, this ensures optimal drainage of rainwater without it remaining in the trench half-element.
[0017] Another advantage of the infiltration trench half-element is that at the free ends of at least one outlet section of the settling arrangement, either a first connecting element and / or a second connecting element is arranged. This makes the infiltration trench half-elements very quick and easy to assemble when used as intended.
[0018] A further advantage of the infiltration trench half-element is that the first connecting element and the second connecting element have a complementary shape at least partially at the free ends of at least one outlet section of the settling arrangement. REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie. Such infiltration trench half-elements are therefore very easy and, in particular, error-free to assemble.
[0019] Another advantage of the infiltration trench half-element is that the first and second connecting elements can be joined at the free ends of at least one outlet section of the settling arrangement. Therefore, infiltration trench half-elements assembled in this way can be quickly, easily, and without tools assembled into infiltration trench components when used as intended.
[0020] Another advantage of the infiltration trench half-element is that the lowering arrangement includes at least one stiffening element. This makes the infiltration trench half-elements very stable during both transport and installation, thus meeting the relevant legal requirements and enabling economical, cost-effective, and sustainable production.
[0021] Another advantage of the infiltration trench half-element is that the settling section and the discharge section are connected to each other via at least one stiffening element. This measure also increases the stiffness and strength of such infiltration trench half-elements.
[0022] The infiltration trench half-element is advantageously designed such that the at least one outlet section has at least one first stiffening element projecting approximately orthogonally from its surface and / or at least one second stiffening element and / or at least one third stiffening element. This advantageously results in the infiltration trench half-elements being very easy and stable to install.
[0023] Advantageously, the infiltration trench half-element is designed such that at least two first stiffening elements of the at least one outlet section are connected to each other via at least one third stiffening element. This measure advantageously optimizes and improves, in particular, the stiffness and strength of the infiltration trench half-elements.
[0024] Furthermore, the infiltration trench half-element is designed such that the third stiffening element of the at least one outlet section has at least one connecting element. This advantageous design measure, REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie, leads not only to easy assembly but also to optimal stiffness and strength of the infiltration trench half-elements.
[0025] Furthermore, the infiltration trench half-element is designed such that the surface of the settling section facing the at least one outlet section has at least one groove with a width of 0.5 mm to 5 mm, preferably 0.75 to 4 mm.
[0026] The infiltration trench half-element is also designed such that the surface of the settling section facing the at least one outlet section has at least one groove with a depth of 0.5 mm to 3 mm, preferably 0.75 mm to 2 mm. This advantageously enables the infiltration trench half-elements to optimally transport and distribute both the liquids to be transported and the suspended solids contained therein when used as intended.
[0027] The infiltration trench half-element is further designed such that the surface of the settling section facing the at least one outlet section has at least one groove arranged approximately parallel to the stiffening element.
[0028] Furthermore, the infiltration trench half-element is designed such that the surface of the settling section facing the at least one outlet section has at least one groove arranged approximately orthogonally to the stiffening element. The infiltration trench half-elements can therefore be very easily optimized for the quantity of liquids to be transported as well as the amount of suspended solids contained therein.
[0029] Furthermore, the trench half-element is designed in such a way that at least one outlet section has at least one infiltration section.
[0030] The infiltration trench half-element is further designed such that the infiltration section of at least one outlet section has a large number of openings. This allows the infiltration trench half-elements to be designed in a variety of geometric ways and adapted to the corresponding quantities of liquids to be infiltrated.
[0031] The infiltration trench half-element is designed such that the infiltration section of the at least one outlet section is located between two opposing, first stiffening elements. This design feature advantageously optimizes the stability and strength of the infiltration trench half-element. REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie
[0032] Furthermore, the infiltration trench half-element is designed such that the drop-off arrangement has at least one connecting element. This allows individual infiltration trench half-elements to be positioned and assembled into infiltration trench components very quickly and easily.
[0033] The infiltration trench half-element is further designed such that the settling section of the settling arrangement has at least one second connecting element at at least one free end. This measure also ensures that infiltration trench half-elements can be assembled quickly and without errors into infiltration trench components.
[0034] A further advantage of the trench half-element is that at least one outlet section of the settling arrangement has at least one first connecting element at at least one free end.
[0035] A further advantage of the infiltration trench half-element is that at least one outlet section of the settling arrangement has at least one receiving element such as shown at at least one free end. Advantageously, the infiltration trench half-elements can therefore be installed easily and without errors.
[0036] The infiltration trench half-element is further designed such that at least one free end of the first outlet section is connected to at least one free end of the second outlet section via at least one stiffening device.
[0037] Furthermore, the infiltration trench half-element is designed such that at least one stiffening device is arranged in at least one receiving element at at least one free end of the outlet section. This in turn leads to very simple and error-free assembly of the individual infiltration trench half-elements.
[0038] A further advantage of the infiltration trench half-element is that it consists of or contains a polymer material, preferably a thermoplastic polymer, in particular a polyolefin such as polyethylene, polypropylene, polybutylene, or a copolymer of the aforementioned, or a mixture thereof, or a polyvinyl chloride, a polyester, or a polycarbonate. Such infiltration trench half-elements are therefore economical, cost-effective, and sustainable to manufacture, have a low weight, and are completely corrosion-resistant.
[0039] Alternatively, the locking mechanism could be manufactured using an additive manufacturing process, such as 3D printing. REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie
[0040] For the production of the trench half-element, it is advantageous to use machine-readable, three-dimensional models. The invention also includes a method for generating a machine-readable, three-dimensional model for use in a manufacturing process for a trench half-element. This method particularly includes inputting data representing a trench half-element into a data processing machine and using this data to represent a trench half-element as a three-dimensional model, wherein the three-dimensional model is suitable for use in the production of a trench half-element. The trench half-element can be produced wholly or partially using a line-by-line or layer-by-layer manufacturing process.
[0041] The use of a 3D dataset during assembly or manufacturing is highly advantageous. The process also includes a technique in which the input data is processed by one or more 3D scanners, which operate either on contact or non-contact. In the latter case, energy is emitted onto a half-element of the rigolen system, and the reflected energy is received. A virtual three-dimensional model of this half-element is then generated using computer-aided design software. The manufacturing process can include an additive manufacturing process, specifically selective laser melting (SLM), selective laser sintering (SLS), selective heat sintering (SHS), selective electron beam melting (EBM / EBAM), or binder jetting.
[0042] The manufacturing process may include an additive manufacturing process, in particular welding, wax deposition modeling (WDM), contour crafting, metal powder deposition (MPA), plastic powder deposition, cold gas spraying, electron beam welding (EBW), or fused deposition modeling (FDM) or fused filament fabrication (FFF). The manufacturing process may also include an additive liquid material process, in particular stereolithography (SLA), digital light processing (DLP), multi-jet modeling (MJM), polyjet modeling, or liquid composite molding (LCM). Furthermore, the manufacturing process may include other additive layer-by-layer processes, in particular laminated object modeling (LOM), 3D screen printing, or light-controlled electrophoretic deposition.
[0043] The trench construction element consists of at least two interconnected trench half-elements according to the previous descriptions, wherein a first settling arrangement forms a first REHAU Industries SE & Co. KG Rehau, November 7, 2024 Int. Ref: 24.033 dr.schie
