Description

The invention relates to a drainage system, and components for forming the drainage system.

Rainwater infiltration systems are becoming increasingly important because there is a need to supply water to the soil, which is deposited on sealed surfaces such as roofs or concreted or paved open spaces, to ensure proper drainage without soil erosion.

Such infiltration devices can be created for example in the form of gravel pits or gravel channels. However, it has recently become more and more prevalent to form such infiltration devices also called box-like trenches in the ground, wherein individual components are used, which overall create a large cavity. In particular, such rigs are assembled from plastic lattice boxes, wherein plastic lattice boxes enclose a large cavity and at the same time can be flowed through well. In addition, such plastic lattice boxes are designed so stable that a plurality of these plastic lattice boxes can be stacked on top of each other and possibly even be driven by vehicles. Such lattice boxes stack to serve as a rigole additionally wrapped with a so-called geotextile, which allows infiltrating the water from the trench into the surrounding soil. The rig also serves as a collecting container, which slowly releases accumulating rainwater.

Such systems are known in the art.

From the EP 1 416 099 B1 For example, there is known a drainage cell for a groundwater handling system having a housing defined by perforated confining walls, a perforated base and an open top, with a plurality of individual upstanding connector elements going up from the base towards the open top and connecting means comprise, which are designed for connection of two cell housings, which are arranged in use with their open tops substantially parallel. The connecting means in this case has a separate device, which is designed for an intermediate circuit between two cell cases whose open top opposite. The separate device in this case has a grid which defines a plurality of individual inner or outer connecting means, which are designed for connection to a respective outer or inner connector element of a cell housing.

From the EP 1 452 653 B1 a seepage system is known, which serves to build a water storage and / or retention device of connectable infiltration modules and corresponding connecting elements. The infiltration modules can be connected to one another by means of connecting elements and the layers can be connected to one another by means of the same connecting elements. In this case, the infiltration modules of two at least substantially identically manufactured half-shell elements which are composable, whereby the half-shell elements as such by means of the same connecting elements releasably connectable to the infiltration modules and composable and this connecting element is provided with at least two differently shaped locking elements, wherein in the assembled state a latching element when installed as intended a laying in the vertical direction and the other locking element determines a simultaneous installation in the horizontal direction and limited.

From the DE 202 21 567 U1 a trench unit is known, which is formed substantially as a hollow body and has a base wall and a plurality of connecting walls which protrude from the base wall. A portion of this wall is permeable to liquid, the walls defining a fluid receiving volume and a channel extending substantially parallel to the base wall extending over a major portion of the trench unit and being open at both longitudinal ends thereof. This channel is intended to be designed as an inspection channel by stiffening or stabilizing ribs are provided below a base surface of the channel and / or a small portion of the total area of the base surface of the channel is pierced by openings and / or it is bounded by at least two connecting walls which at least partially are formed as a grid structure. In practice, such trench units show two box bodies separated by a channel, which are each framed by perforated walls, wherein between the box bodies the channel bottom is formed as a roadway for an inspection device.

From the DE 101 23 754 is a trench assembly with one or more Rigolenbauteilen known to a trench pool, can be assembled, the trench components are designed as a water-absorbing body and at least one of these water-absorbing body has continuous water pipes and the continuous water pipe has openings through which water can enter into the water-absorbing body of the trench component ,

From the DE 298 23 806 a seepage device is also known, which is constructed in segments, wherein the segments are plastic lattice packings and the individual layers of plastic lattice packs consist of module-assembled lattice elements, wherein the individual layers are secured against relative displacement among themselves by means of corresponding connecting elements.

From the WO 02/14608 A1 a structural component is known, which is also designed in the manner of plastic mesh boxes, wherein the elements are each similarly formed so that they can be plugged with their open sides on each other and thereby form a closed box. The boxes can be attached to each other with dovetail connectors.

The object of the invention is to provide a drainage system, which can be produced inexpensively, is modular and which is flexible in terms of its structure.

The object is achieved with a drainage system having the features of claim 1.

In addition, it is an object to create components for the drainage system.

The object is achieved with components having the features of claim 9. Advantageous developments are characterized in the dependent subclaims.

The drainage system according to the invention is formed from components, wherein the components are generally open at the bottom boxes that have a top wall, two side walls and two end walls and, for example, have a square or rectangular base. The bottom wall and the side wall and the end walls are in this case formed with openwork fields, for example in a grid or honeycomb pattern, which are integrally limited by columns of a solid material. Within the space enclosed by the ceiling wall and the floor and the end walls cavity preferably extending over the height of the side or end walls support columns that project from the top wall to the open side. The fact that the side and end walls are formed more or less similar and also the top wall is formed with similar perforated fields, a very simple and inexpensive construction is achieved in addition achieves high flexibility.

In a square structure, for example, the side walls have three grids, which are bounded by the corner pillars and two side columns, the end walls are formed similar.

In addition, according to the invention, a base plate element is used, wherein the base plate elements are connectable to one another to form a large base plate to which the downwardly open box-like elements are connected by means of click-latching connections. Here, both the base plate elements and the attached boxes with each adjacent elements or adjacent boxes by means of simple connectors are connected to each other. In an advantageous embodiment, at least in two opposite side walls or end walls in each case opposite a recess or a grid compartment released.

The embodiment of a component in which at least one central compartment is kept free at the front side differs from an embodiment of the component in which it is enclosed on all sides with compartments in that two components with the areas of the side compartments can be stacked by the free central compartment. In this respect, this can reduce the stack volume. After the stacked for transport components are separated from each other, the open Gefach can be closed with an appropriate closure device before laying or after laying, so that even a closed all-round component or a hollow body closed on all sides (after laying) is achieved.

In order to achieve a staggered stacking and thus a higher stability, additional elements can be provided which in particular have 1/3 of the width of a previously described element, but otherwise are constructed identically. This can be analogous to an offset brick masonry in the edge region use third elements, which are covered in the next stack level of a full element, so that a stability increasing offset is made. According to the invention, between the individual elements, i. H. each of the third elements each 1/3 space are left, which is then bridged in the next stack level of other elements. As a result, passages are created between the components to rinse, for example, the trench.

In the invention it is advantageous that a drainage system is created with a very high variability, whereby also different components can be combined with each other and thus a maximum flexibility can be achieved both in terms of stability and spatial extent, but also in terms of compressive strength in some areas. In particular, can be achieved by appropriate arrangement of third elements in a staggered walling a very high compressive strength, so that areas can be created which z. B. can be traveled on the surface with motor vehicles.

An inventive component 1 . 1a ( 1 ) is a downwardly open grid box 1 with, for example, a square or rectangular base, wherein the component 1a a ceiling wall 2 owns and from the ceiling wall 2 at the outer longitudinal edges 2a two opposite side walls 3 and two end walls orthogonal to them 4 available.

The ceiling wall 2 has an aperture pattern, the apertures 5 for example, square or rectangular openings 5 are the ceiling wall 2 from their top 6 or outside 6 to her bottom 7 or inside 7 succeed. These recesses 5 are arranged, for example, along the longitudinal edges in three groups, wherein in each corner a group is arranged with four by four openings, which between them each a group with four times nine openings 5 limit. Between the groups are footbridges 8th arranged, with the webs 8th each from one side edge of the ceiling wall 2 extend to the opposite edge, so that a total of four webs are formed, which meet at four crossing points, wherein through the webs 8th a central recess field is formed with, for example, seven by nine recesses 5 ,

The bridges 8th are in contrast to the opening pattern, for example, fully formed or formed as a hollow body, wherein for venting or for manufacturing reasons, the webs 8th at the top of the ceiling wall via openings 8a can dispose of.

From the starting points of the footbridges 8th in the crossing points of the footbridges 8th and in the corners of the ceiling wall 2 hollow columns extend 10 . 11 downward. This will become four inner columns 10 and twelve outer columns 11 educated. The outer columns are part of the side walls 3 and the end walls 4 , where the side walls 3 and the end walls 4 one corner column each 11a own together and the corner pillars 11a every wall 3 . 4 two side columns 11b between them.

The columns 11 the side walls 3 are with bars 14 in the area of their free ends 15 connected so that the webs 14 and the columns 11 the side wall 3 and the longitudinal edge 16 the ceiling wall 2 to limit three divisions between themselves.

The corner pillars 11a and the side columns 11b each define a side drawer 17a , the side columns 11b limit a middlefold between them 17b , This is of course only to be understood as an example, depending on the length and / or width of the component 1 instead of one can also have several mediums 17b and thus more than two side columns 11b to be available. The number of center columns 11 and the bridges 8th increases accordingly and corresponds in particular to the number of side columns 11b , The side folds 17a have a width of a and the average 17b a width b. The width a extends from the outer edge of the associated corner column 11a to the transverse center of the following side pillar 11b , The width b of the median fold extends from the transverse center of a side pillar 11b to the next side pillar 11b ,

Between the columns 11 . 11b formed cavities in the ceiling wall 2 are in the ceiling wall 2 insertion 12 formed, wherein the insertion openings 12 for example, in cross section are square or rectangular and from the outer longitudinal edge 2a or one of the outer longitudinal edge 2a be formed narrow footbridge. In the outer narrow longitudinal edge 2a can in the area of the opening 12 a small step will be available. The openings 12 serve to receive connecting elements ( 6 . 8th ).

The sections 17 have a height h, the height of the side wall 3 or end wall 4 corresponds, with the height h from the outer longitudinal edge 2a the ceiling wall 2 to the lowest or outermost side edge 14a of the bridges 14 enough.

These definitions apply equally to the sidewalls 3 as well as for the end walls 4 ,

The widths a and b can be the same, so that at three compartments 17 a third of the respective side or end wall 3 . 4 through the divisions 17 takes place. However, the widths a and b can also differ from each other. The compartments are with a honeycomb or grid pattern of bars 19 filled.

In the area of the front sides 4 are only from the corner pillars 11a to the next side pillar 11b Stege 14 arranged so that no middle shelf 17b is formed.

The columns 10 . 11 stand over the footbridges 14 with free ends 15 addition, with the free ends 15 are formed so tapered that in a stack of two components 1 on each other the tapered ends 15 in the hollow pillars 11 an underlying device 1 essentially form-fitting inserted. To make a connection have the columns 10 . 11 in the area of the ceiling wall 2 recesses 20 , which are formed, for example, square or rectangular. The recesses 20 Here are a small piece of the outer longitudinal edge 2a removed, with the corner posts 11a one recess each depending on an outer side 20 and thus two recesses 20 own and the side columns 11b in the area of the side wall 3 . 4 one outwardly facing recess 20 , The central pillars 10 may be formed without a recess or optionally one, two, three or four recesses 20 have.

At the free ends 15 the columns 10 . 11 are corresponding resilient latching hooks 21 ( 17 ) provided by the insertion of the column 10 . 11 into the column below 10 . 11 first pressed inwards and when reaching the recess 20 snap outwards and engage behind in the manner of a locking element in the underlying column so that a solid, locking connection is ensured.

In this embodiment of the device 1a is an advantage that due to the free mediums 17b the front ends 4a the components 1a stacked one inside the other can be transported, in particular without the risk that the components 1a accidentally lock together. Nevertheless, to achieve a box closed on all sides are closing elements 30 intended.

These closure elements 30 are plate-like formed with a base plate 31 , where the base plate 31 has a width which corresponds approximately to the width b, and has a height which is approximately equal to the height h or slightly lower.

From the base plate 31 extends to one side an inner frame 32 , where the inner frame 32 is designed so that it on the one hand approximately the surface of a Mittelgefachs 17b encloses and on the other hand is designed so that it is substantially positive fit to the side columns 11b and an outer longitudinal edge 2a is applied. The from the inner frame 32 enclosed area is in the plate 31 pierced designed so that it can be flowed through.

The openings can be designed so that, starting from a transversely but displaced with respect to the height from the middle tubular element 33 circular elements are arranged, wherein a first circular element 34 is arranged concentrically around the tubular element and tangentially to the nearest side of the frame 32 is applied. Two larger circular ridges are around the circular ridge 34 arranged around, wherein a first circular web 35 eccentric but also tangential at the same point as the circular ridge 34 is arranged adjacent to the frame and a next larger eccentric circle is arranged around it ( 7 ). With these circles, with ribs 37 spaced from each other, pipe connections can be realized to set up flush pipes.

At the inner frame 32 are spaced from each other locking elements 40 arranged, wherein the locking elements 40 from plate-like elements 41 which exist over the frame 32 from the plate 31 protrude away. At the plate-like elements 41 are outwardly facing latching hooks 42 arranged. The distance between the latching hook on the one hand and the inner surface of the plate 31 on the other hand, it is so dimensioned that this is approximately the thickness of the side columns 11b equivalent.

This allows the closure element 30 perfectly fitting with the frame 32 between two side columns 11b put it, while it is inserted from the outside with the locking hooks 42 behind the columns 11b passes and the closure element accordingly firmly with the component 1 connected.

In a corresponding stack of components 1a ( 11 ) All openings are thus closed.

In a further advantageous embodiment of the device 1b ( 2 ) are all divisions 17a . 17b present, wherein the compartments are filled with a honeycomb pattern, which consists of webs 19 is formed.

A further advantageous embodiment of the device 1a Although the same is formed with respect to the length of the side walls, but with respect to the width, ie the length of the end walls, but has a reduced width, in particular in the periphery of a Seitengefachs 17a , where the side drawer 17a in this case of two corner columns 11a is limited. Incidentally, the same parts are provided with the same reference numerals. The front has a width, for example, a Gefach 17a corresponds, but half the column width of a corner column 11a come in addition. This results in otherwise identical dimensions, that the end wall 4 Has dimensions that in about one third of the already described components 1a . 1b equivalent.

To create the drainage system are in addition to the components 1 baseplates 50 intended. The base plates 50 correspond in their design a ceiling wall 2 However, instead of continuing columns only corresponding recesses are also present with the corresponding recesses, so that columns are inserted there. Here, the same components are provided with the same reference numerals. The base plate 50 has a base, the base of a ceiling wall 2 equivalent. Between one recording each 51 for a corner column and a receptacle 52 for a side pillar 11b is directly adjacent to an outer edge 50a the base plate 50 a recess 53 present, which is square or rectangular in cross-section, for example, and serves to receive connector elements.

In a further embodiment of the base plate is the base plate 60 designed for narrow elements with, for example, one third of the end face, so that this base plate about one third of the base plate 50 includes. Otherwise, it is the same design, wherein the same components are provided with the same reference numerals.

The connecting elements ( 6 . 8th ) are designed so that they fit into the appropriate recordings 53 the base plates, but also the blocks are inserted, wherein the connecting elements, if they are to connect adjacent base plates and components stacked thereon, of two columnar bodies 71 consist, for example, drehrund, from the inner contour ago the insertion 53 or z. B. octagonal are formed. These tubular bodies have a connecting web approximately in the axial center 72 holding the two tubular body 71 connects to each other while keeping a distance between the two tubular body 71 forms each other, which is dimensioned such that the peripheral outer edge of the ceiling wall 2 or the plates 50 . 60 there is space between them, which means that two of the circumferential edges have to fit. In order to ensure the greatest possible stability of the connection, strip-like projections 73 on the tubular bodies 71 be arranged so that they are on the peripheral wall 74 extend longitudinally, wherein these are formed so that in a round tubular body 71 or, for example, an octagonal tubular body 71 this in the outwardly facing corner regions of the insertion 43 protrude so that the tubular body 71 in the insertion openings 53 supported with at least three surfaces.

In one embodiment, only the base plates 50 . 60 interconnects or a top layer of components 1 connecting together, are the tubular body 71 the connector 70 formed only halfway up, wherein the connecting web forms a kind of base plate.

A method of constructing a drainage system provides, for example, first of base plates 50 and connectors 70 to lay a composite base plate, which is the footprint of the planned stack of building elements 1 equivalent. After this base plate has been completed and possibly has already been placed on a Geovlies, become first components 1 placed accordingly on the base plate, with the free ends 15 the columns 10 . 11 in the corresponding insertion openings 51 . 52 be inserted and in the presence of corresponding locking elements 40 and corresponding detent openings 20 lock there and the component 1 firmly hold to the base plate ( 13 ). Subsequently, the components are in the same way 1 further stacked until a desired space of the elements is stacked, wherein each of the components with each other a layer and with the overlying layer with the corresponding connectors 70 get connected. Subsequently, those with components with free Mittelgefachen 17b the still accessible from the outside Mittelgefache 17b with the elements 30 closed in the manner already described.

In a further developed method for creating the drainage system ( 15 to 19 ), the drainage system is made of wide construction elements 1b , which are closed on all sides, and the narrow components 1c designed so that an offset can be achieved in the manner of masonry. For this purpose ( 16 ) a base plate with plates 50 and 60 as well as connectors 70 designed, with narrow base plates 60 and wide base plates 50 be laid alternately, wherein at one end of the planned base plate instead of an alternate laying two narrow plates 60 consequences. On the two narrow plates 60 and a third of the attached wide plate 50 becomes a broad component 1b arranged and latched as already described. The next big component is with a Gefachabstand of the first component 1b removed placed on the base plate and there latched and then also with a Gefachabstand a narrow component 1c placed on the base plate and locked so that when using three components 1 two distances are respected. The next layers ( 18 ) are placed accordingly offset so that any space between the components 1b . 1c subsequently covered by a wide component. Of course, this type of stacking can also be extended significantly in terms of expansion over three components in width and is shown here only by way of example. After reaching the desired stack height ( 19 ) to cover also the clearances in the uppermost layer and to form a plane, the base plates 50 . 60 placed on top of the stack from above and connected together. The outwardly facing openings of the voids become with the cover elements 30 closed, because they have the same dimensions as the missing partitions in components without Mittelgefache 17b ,

Of course, the offsets and distances within the layers can be realized in both spatial directions (not shown).

In a further embodiment of the system ( 20 to 24 ) are only narrow components 1 used, with the narrow components 1 on a wide base plate 50 be placed so that they close laterally and maintain a distance of a Gefachbreite between them. The next narrow components are accordingly placed offset by 90 ° on the underlying components, also with the corresponding distance, so that in any case an offset and thus an increase in stability is accompanied.

After the stack has reached the desired height, a wide base plate is placed at the top. The outward-facing openings of the spaces between the components 1 then with the cover elements 30 locked.

In the case of the abovementioned system, it is advantageous that, when components with missing center diameters are used in the end faces, good stackability during transport is possible.

In particular, in the method of advantage that a system can be created in which fewer components are needed because they can be installed with distance from each other, which allows for a staggered walls and thus greater stability and on the other hand, the use of materials and thus reduces the weight of the drainage system and increases the water absorption capacity.

It is advantageous in the case of the components that they can be produced very simply and inexpensively by injection molding, have high stability and, in particular, in conjunction with the base plates 50 . 60 are very flexible. By using the cover elements 30 Weight is also saved, since only the outer access to the interior, which is formed by the components, must be closed.
