Description

Rigolenhalbelement

The invention relates to a Rigolenhalbelement.

In addition, the invention also relates to a Rigolenbauelement and a receiving, storage or infiltration device, which is constructed from Rigolenbauelementen.

Rigulas used for receiving, storing or infiltrating fluids, in particular rainwater, are assembled from individual elements. In particular, this rigidity half-elements are used, which have a base grid, which rise from the base grid about perpendicular columns. To connect the Rigolenhalbelemente at the tips of the columns so at the column ends, which lie opposite the base grid, connecting devices are used. For this purpose, the columns can either be placed loose on one another or joined together by means of latching connections.

To arrange such Rigolenhalbelemente in the production, storage and transport space-saving, the pillars are hollow, so that such Rigolenhalbelemente are stackable by the columns of an adjacent arranged Rigolenhalbelements are inserted into the cavity of the columns of a Rigolenhalbelements.

The trench half elements as part of a receiving, storage or infiltration device must withstand certain forces, which originate on the one hand from the underground installation of such a receiving, storage or infiltration device.

This affects an earth pressure and possibly also the hydrostatic pressure of the rainwater collected in them, on the other hand also traffic loads are to be absorbed by the traffic routes located above.

For forwarding the forces in the vertical direction in this case serve the columns of Rigolenhalbelemente. These must be designed according to the mechanical or static requirements. When designing the columns for a trench half-element in view of the requirement for the transmission of forces, there are always problems, especially if this type of columns should also be designed for the possibility of stacking the trench half-elements.

This is where the invention, which has set itself the task of specifying a Rigolenhalbelement, which overcomes the above problems. Another object of the present invention is to provide a trench component.

Finally, it is also an object of the invention to specify a receiving, storage or sealing device which is constructed from trench components. The solution of the first task is carried out according to claim 1.

It has been recognized in the context of the present invention that a trench half-element achieves the object of the present invention if the trench half-element comprises a base lattice and at least one column connected to the base lattice and approximately perpendicular to the base lattice, the end opposite the base lattice a surface having a first connecting element or a second connecting element.

The column has a wall delimiting a cavity of the column, the wall of the column being equally inclined along its entire length along the entire circumference of the column with respect to a normal which is perpendicular to the base grid.

By the measure that the wall of the column along the entire circumference of the column against a normal, which is perpendicular to the base grid, is the same inclined over its entire length, it is possible on the one hand to provide a very stable column for a Rigolen- half element, which Incorporate forces and can transmit, and on the other to ensure the stackability of Rigolenhalbelemente.

In the context of the present invention, such a trench half-element according to the invention can be designed in a particularly advantageous manner such that the inclination of the wall of the column along the entire circumference of the column relative to a normal, which is perpendicular to the base grid, over its entire length 2 ° to 8 °, preferably 2 ° to 4 °.

An inclination of the wall of the column along the entire circumference of the column with respect to a normal, which is perpendicular to the base grid, in the aforementioned ranges is particularly favorable in terms of optimum power transmission of the pillar of the trench half-element and also the stackability of such Trench half-elements. With particular advantage may be provided in the Rigolenhalbelement according to the present invention that the wall of the column along the entire circumference of the column over its entire length is the same thickness.

By forming the wall of the column along the entire circumference of the column over its entire length in a uniform thickness, such a trench half-element according to the invention can be produced in a simple and reproducible manner.

As a manufacturing process can be used in particular a molding process for polymer materials, such as an injection molding process. In an injection molding process, the same wall thickness brings many advantages, in particular with regard to the cooling process and the avoidance of sink marks and internal stresses in the component.

It may prove to be very favorable in the present invention, if it is provided that the Rigolenhalbelement is formed such that the column over its entire length has a cross section which is composed of curve sections and / or straight lines and / or the corners.

A trench half-element, in which the column over the entire length has a cross-section, which is composed of curve sections and / or lines and / or corners can be easily produced, has a high stability and is particularly adapted to transmit forces.

A stackability of such Rigolenhalbelemente is guaranteed in this way. In a particular embodiment of the present invention can be provided that the column of Rigolenhalbelements has an approximately square cross-section. The provision of a square cross-section for a column of a trench half-element leads to a uniform introduction of forces into the column, whereby the column can then forward these forces evenly.

Moreover, the production of a trench half-element with a column having an approximately square cross section is particularly simple. In a preferred embodiment of the present invention, it can be provided that an entry is formed on at least one side of the wall of the column. In particular, it can be provided that in the presence of a column with an approximately square cross section on all four sides of the column such an entry is formed. In this case, it is preferred if all four sides of the column have similar and identically shaped projections. Manufacturing technology, such a Rigolenhaibelement can be easily realized. In this way, an orientation of the Rigolenhalbelements is ensured when stacking, which has few or no restrictions.

By forming an entry on one side of the wall, this wall can be stabilized in a particularly advantageous manner and thus transmit forces that are introduced into it.

The stackability in such Rigolenhalbelementen having an entry on at least one side of the wall of the column is ensured.

In an advantageous embodiment, the column of the trench half-element may have at least one, preferably several mirror planes. This measure results in a column of high symmetry, which absorb forces in a special way and can forward along their length.

It may prove to be particularly favorable in the present invention, if it is provided that the first connection element and the second connection element at least partially have a mutually complementary shape and the first connection element and the second connection element are plugged together. So it is in easy way possible to form a Rigolenbauelement of two Rigolenhalbelementen by connecting the two Rigolenhalbelemente.

It can prove to be particularly advantageous in the present invention if it is provided that the rigid-half element consists of or contains a polymer material, the polymer material preferably being a thermoplastic polymer material, in particular a polyolefin, such as a polyethylene, polypropylene, Polybutylene or a copolymer of the foregoing or a blend composition of the foregoing, or a polyvinyl chloride or a polyester or a polycarbonate.

The abovementioned polymer materials are easily moldable, stable, inert, durable, mechanically stable, resilient and inexpensive to buy. Rigolenhalbelemente can be formed from the above polymer materials in a simple manner. This can be done, for example, in an injection molding process or in another process of polymer processing and molding.

Alternatively, it is also possible that the Rigolenhalbelement using a generative manufacturing process, in particular in one piece, for example by a 3-D printing method, is made.

For this purpose, data processing machine-readable three-dimensional models can advantageously be used for the production.

The invention also encompasses a method for producing a data-processing machine-readable three-dimensional model for use in a manufacturing method for a trench half-element. In particular, the method also includes inputting data representing a trench half-element into a data processing machine and using the data to represent a trench half-element as a three-dimensional model, the three-dimensional model being suitable for use in producing a trench half-line.

Also included in the method is a technique in which the inputted data of one or more 3D scanners operating on either touch or non-contact, the latter being given energy to a trench half-element and the reflec- a virtual three-dimensional model of a gypsum half-element is generated using computer-aided design software. The trench half-element may be wholly or partly made using a line-building or layer-building manufacturing process.

In particular, the Rigolenhalbelement may be wholly or partially line by line or layer by layer produced by a material.

It can be used with great advantage, a 3D data set during construction or in the production.

The solution of the further object of the present invention to provide a Rigolenbauelement, is carried out according to claim 9. In the present invention it has been recognized that a trench component is easily accessible, if it is provided that two interconnected Rigolen lenelemente, as described above to be connected with each other. For this purpose, it is provided that the first Rigolenhalbelement at the at least one pillar a first connecting element and the second Rigolenhalbelement on the at least one column has a second connecting element, and wherein the first connecting element and the second connecting element are plugged together and the two Rigolenhalbele- mente so interconnected ,

Such trench components can be formed in particular from identically shaped trench half-elements such that in the case of a plurality of columns each pillar is connected to a pillar of the further trench half-element, so that there are no unconnected pillars in the two trench half-elements.

In another connection situation, provision may be made for the first half-member having a plurality of columns to be connected to a second half-member having a plurality of columns in such a way that not all the columns are connected to one another so that there are still unconnected columns. In this construction situation, it is possible, for example, to construct a "masonry composite", wherein the trench half elements are arranged, for example, so that they are each connected to two further half trench elements. But there are also other Verbausituationen in which more than two Rigolenhalbelemente are connected to a Rigolenhalbelement.

The last object of the present invention to provide a receiving, storage or seepage device is achieved according to claim 10.

It has been recognized in the present invention that a receiving, storage or infiltration device is then upgraded technically particularly if it is composed of a plurality of Rigolenbauelementen, as described above.

Such a receiving, storage or infiltration device can be used in a particularly preferred manner as a trench, as a retention basin or as a storage tank. In a further development of the present invention, such a receiving, storage or infiltration device is surrounded by a fleece, so that no soil is washed into the device from the outside or that no solids from the interior reach the ground.

The present invention is widely used in the field of rainwater management. However, the invention can also be used with great advantage in industrial applications, in swimming pools, in agriculture and fish farming, as well as in other fields.
