Description

LIFTING BOX WITH A RECEPTION FOR A STABILIZER ELEMENT AND RIGOLENSYSTΞM WITH SEVERAL OF SUCH LIQUIDATION BOXES

The invention relates to a percolator box for a trench system, comprising at least one structural body having an open, three-dimensional and inherently stable structure, and a trench system with a plurality of such percolator boxes.

Pontoons are underground facilities that serve for the infiltration, retention and possibly also use of water, especially rainwater. Rigolene systems are used, for example, when large quantities of rainwater are discharged from a non-infiltratable area, which should be distributed as far as possible below the surface or at another location for infiltration.

It is known to use modular rigging systems that can be realized from several, in particular the same, percolation boxes of any size. Depending on requirements, one or more horizontal levels of percolator boxes are introduced into the soil and surrounded by a geo-fleece, which largely prevents the penetration of soil into the trench system. Depending on the application, the trench system also has at least one inflow and / or at least one outflow, which serve for feeding or discharging water.

In this case, plastic structural bodies produced as injection molded parts are usually used as percolating boxes, it being customary to assemble two (or more) structural bodies, in particular centrally to form a percolating box. The structures of the structural bodies formed from injection-molded plastic, essentially hollow, that is, at least partially fluid-permeable, are usually designed such that the percolating box can carry the loads acting on them. The structure is therefore substantially lattice-like and composed of columns, struts, grid sections and the like such that the desired bearing effect of the percolation box is achieved. Such, often also determined by the use of computers structures generally represent complex three-dimensional structures. It is important to ensure that there is sufficient space for receiving the water, so that the structural body are substantially hollow and open. There are known percolation boxes in which one or more passageways in particular centrally provided, so continuous areas in which there are no elements of the structure. Water can flow substantially unimpeded through these through-channels, and it has also been proposed to design these as flushing and distribution channels, as described, for example, by DE 20 2005 002 169 U1.

In particular, in such percolation boxes, which also have a passage, the static load capacity in addition to the course, of course, the manufacturing costs increasing increasing complexity of the structure certain limits. Injection molded structural body are not very variable in terms of wall thickness and thus the statistical capacity. This is disadvantageous, in particular in view of the various structural requirements imposed on such a rig system. The installation depth of the trench system, that is, the load of the materials above, varies, for example, from a few centimeters up to 10 meters. Furthermore, the additional burden, in particular by above the Rigolensystems occurring traffic, should be noted. While it is conceivable to arrange a rigging system only under a relatively thin topsoil layer, which is neither exposed to pedestrian traffic nor pedestrian crossing, there is often the desire to arrange rigging systems even under surfaces frequently used by motor vehicles of different weights, in particular asphalt surfaces , An example of this is a parking lot called whose water is to be infiltrated in the under him rigging system. Obviously there are a variety of different requirements to which the known Versickerboxen with respect to the statics are hardly adaptable and which can not be realized at all partially. A percolation system comprising a percolator box, which allows high traffic loads with low overlap or large installation depths, is oversized at low loads and therefore not economically competitive.

The present invention is therefore an object of the invention to provide a Versickerbox and a plurality of such Versickerboxen comprehensive rig system, which is variably adjustable for different loads and in particular also allows higher loads than the known in the art seepage boxes. To solve this problem is provided according to the invention in a Versickerbox of the type mentioned that at least one structural body passing through the recording, which extends parallel to a loading direction of the structural body, for at least one elongate stabilizing element, in particular a rod is formed. In particular, the percolator box may comprise at least two similar, composite structural bodies, wherein the receptacle penetrating the structural bodies extends perpendicular to a horizontal plane of assembly of the structural bodies.

Although in the following description the frequently used case of two similar, centrally composed structural bodies is often discussed as an example, it should be emphasized that the idea according to the invention can likewise be applied to infiltration boxes consisting of only one or more than two structural bodies.

It is proposed to expand the already carrying, for example, of two similar structural bodies Versickerbox by at least one recording that in the installed state in the loading direction, in particular vertical direction, runs, and an elongated stabilizing element, in particular a rod or a plate, can record. In this way it is on the one hand advantageously possible to adapt the Versickerbox to different expected loads. If a very low load is expected, for example, the composed of two structural bodies Versickerbox can be used without a stabilizing element. If vertical loads are to be expected, to which the structurally stable structure of the structural body may no longer be able to cope, for example a particularly high installation depth or a particularly high traffic load, then an elongated stabilizing element which in particular substantially completely and / or over the entire height of the Versickerbox fills, be used. With particular advantage, a plurality of different types of stabilizing elements suitable for insertion into the receptacle are provided in such a system, so that a further variation can be provided thereby. The stabilizing element thus acts as a kind of additional vertical column, which absorbs vertically acting loads and thus gives the Versickerbox greater stability. Depending on how stable the elongated stabilizing element is selected, it is therefore possible to vary the vertical load capacity depending on the load case and need. A further advantage of the present invention is given if the elongate stabilizing element, which in particular corresponds in length substantially to the height of the percolating box, is continuous in the region of the plane of composition, so that it can also absorb horizontal shear forces between the structural bodies.

In summary, the invention Versickerbox thus represents a structural unit whose stability can be increased by using an elongated stabilizing element in two respects, so that higher loads, for example, by traffic, or higher installation depths are made possible. In particular, by providing differently stable stabilizing elements or even no stabilizing elements in the receptacles, it is possible to achieve a variation in the load capacity as required.

The structural body can be made in particular of plastic in an injection molding process, as is known in the art. Polypropylene and / or polyethylene can be used as the plastic. As already shown by the injection molding process, the structure of the structural body is thus a total coherent structure that is substantially hollow, so at least partially fluid-permeable. The structure which can be described as a lattice-like structure is essentially formed by lattice elements, struts, columns, cross connections and the like. In particular, boundary surfaces of the structural body can be formed like a grid.

In an expedient embodiment can be provided in the Versickerbox one, in particular central, or a plurality of passage channels extending in the horizontal direction. Especially in those cases in which the passage channel itself leads to a certain restriction in the maximum achievable load capacity, the stabilization elements to be used in the receptacles provided according to the invention can lead to a significant increase in the load capacity and thus to an extended field of application.

Expediently, a percolating box can comprise two substantially or completely identical, mirror-symmetrically arranged structural bodies at the assembly plane, which thus forms the median plane. If a central passageway is to be provided, in particular two substantially U-shaped structural bodies can be used. It should be noted at this point that the stabilizing element of course need not be made of the same material as the structural body and not by the same method. In particular, it is conceivable to produce the stabilizing element from a more stable material. In this case proves to be particularly useful reinforced plastic, in particular glass fiber reinforced polypropylene. The stabilizing element can be produced for example by an extrusion process.

Although rod-like stabilizing elements have proven to be particularly expedient, it is naturally just as conceivable to provide other forms of stabilizing element. For example, can be used as a stabilizing element, for example, in the side-mounted receptacle plate member. Any possibilities are conceivable within the scope of the invention.

The percolation boxes can be delivered pre-assembled, but it is equally possible to assemble them on site. For example, it is conceivable first to insert / push / beat a stabilizing element into the structural body forming the lower part of the percolating box, in order then to set up the other structural body guided by the stabilizing element. Equally, however, it may also be possible first to assemble both structural bodies, in order to then insert / push the stabilizing element (s) from above.

With particular advantage, the stabilizing element can be a profile bar, in particular with a profile which increases the buckling resistance and / or an outer profile which enables or supports a clamping or press mounting. A profiling of the rod can thus serve on the one hand to fix the rod to form a clamping or pressing support in the receptacle. In this case, for example, in the longitudinal direction of the rod extending webs may be provided, so that the total diameter of the rod at the webs exceeds the recording something. Of course, it is also conceivable in principle to design the rod in such a positive or non-positive manner that a clamping or pressing fixture is provided anyway. Simultaneously or alternatively to the one

Clamping or press mount enabling supporting outer profile can also be a Beulfestigkeit increasing profile, which therefore supports the overall stability of the rod, may be provided. For this purpose, it may be provided, for example, that the rod comprises two concentric tubes with a plurality of, in particular five, radial connecting walls. Thus, the rod is not only stable in the vertical direction, but also against other deforming forces.

However, further embodiments are conceivable for locating the stabilizing element in a location-stable and / or load-bearing manner in the receptacle of the percolating box. In a further embodiment, it may be provided that, in the presence of at least two structural bodies, the stabilizing element comprises a collar arranged in the installed state at the level of the assembly plane for resting on the region of the structure adjacent to the receptacle and / or the receptacles in the region of the assembly plane form a step for Receiving a formed on the stabilizing element, in particular also stepped, thickening. So what is proposed is a kind of collar, a flat, for example, a rod round, protruding surface which rests on the lower structural body and so holds the stabilizing element in a fixed position. Similarly, it is conceivable that both the receptacle and the stabilizing element comprise an in particular horizontally extending step, so that the stabilizing element can rest on the step in the receptacle. For example, in the case of a round receptacle and a round bar adjacent to the plane of composition, the diameter of the receptacle may increase stepwise. A rod to be inserted can then have a correspondingly increased diameter, in particular in the center, so that it can be inserted centrally in the assembly of the percolator box because of the two structural bodies.

Alternatively or in addition to a clamping or pressing support of the rod enabling and / or supporting profiling of the stabilizing element itself can also be provided according to the invention a corresponding profiling on the inner wall of the receptacle. In particular, it proves to be expedient if webs extending in the longitudinal direction of the receptacle are provided for clamping or pressing support of the stabilizing element. Such webs may for example have a thickness of three millimeters, while the wall of the stabilizing element may have a thickness of five millimeters. Then, a clamping or pressing holder, which acts without deformation of the stabilizing element. In a particularly advantageous embodiment of the present invention can be provided that in the region of an upper and / or lower end surface of the Versickerbox a recording horizontally passing through blocking element and / or the dimensions of the recording constricting projection is provided on which the stabilization element is set , In this case, the stabilizing element can consequently redistribute forces acting on the end surface in the region of the bottom surface, so that it acts as an additional stabilizing element over the entire percolating box. In particular, the or at least one blocking element can be breakable, in particular be connected via narrow webs with the inner boundary of the receptacle. This embodiment is particularly advantageous if, for example, a plurality of percolator boxes are to be stacked one above the other in a trench system and it is intended to stabilize all the percolator boxes continuously by means of a common stabilizing element which optionally comprises a plurality of subelements. In this way can be created by breakable blocking elements an "extension" of the recording.

As a further possibility for positionally stable mounting of the stabilizing element in the receptacle, it can be provided that at least one recess corresponding to a latching lug of the stabilizing element and / or at least one latching lug corresponding to a recess of the stabilizing element is provided in the receptacle. Such a snap-in holder also makes it possible, in particular, for certain preferred orientations of the stabilizing element, to enable it via a suitable corresponding location-dependent configuration of latching nose and recess.

For the most uniform possible stabilization support by the stabilization elements in the percolation box, it makes sense to provide more than one, so at least two shots. It has proved to be advantageous to provide at least four receptacles provided in the corner regions of the percolation box, in particular a total of six receptacles. In this case, the receptacles should preferably be arranged so that as far as possible over a large part of the base area of the percolator box, a uniform additional absorption of vertically possible forces can take place. In a concrete example with two substantially U-shaped structural bodies, which thus form a passageway in the center through the percolation box, it can be provided that three receptacles are provided laterally along the through-channel. Incidentally, it is also conceivable, for example for varying the load capacity, to use stabilizer elements only in a part of these receptacles. The number of variations is thus increased. Embodiments with ten receptacles, in which five receptacles are provided, for example, on each side of the through-channel, are conceivable.

As already mentioned, a plurality of percolator boxes are frequently used in rigging systems. The receptacles or the stabilizing elements can advantageously have a configuration which makes it possible to effectively connect adjacent percolator boxes. Thus, it can be provided that in the presence of at least two structural bodies further, at least close to the composition surface edge formed receptacles for connecting elements of at least two adjacent Versickerboxen in the verickeerbox are provided and / or recordings for insertion of particular a recess for the stabilizing element having connecting elements at least two adjacent Versickerboxen are formed. In the case of further recordings, the connecting elements may for example be designed so that they are stationary, in particular form-fitting, formed in a further recordings and a corresponding additional recording in the adjacent Versickerbox. However, it is particularly advantageous, and thus preferred, to use the stabilizing elements themselves by - in particular along the plane of composition - the receptacles are modified so that they can accommodate in addition to the stabilizing elements and connecting elements that connect at least two adjacent Versickerboxen. Alternatively, it is conceivable that the connecting elements also act only on the stabilizing elements, for example by having recesses adapted to the stabilizing elements. In the following, some expedient examples are mentioned for these embodiments. Thus, for example, two connected loops, for example in the form of an eight, designed connecting elements may be used, wherein the loops serve as recesses for adjacent percolation boxes associated stabilization elements. It is equally conceivable to use double or multiple pipe pieces comprising a collar, these being in the assembled state with the collar in the plane of assembly, while the pipe pieces extending on both sides are inserted into receivers and guiding the respective stabilizing element through the central recess is. In this way, an excellent grip is given. In particular, corner pieces can be created, which can also connect four percolating boxes together and hold them in a positionally stable manner. Again, various configurations are conceivable. Expediently, there is also a possibility of already allowing a particularly dimensionally stable assembly of the at least two structural bodies without the use of a stabilizing element. It can thus be provided that the structural bodies in the region of the assembly plane have insertion or latching elements for connecting the structural bodies. Other possibilities, such as sticking of the structural body, but are conceivable.

In addition to the percolating box, the present invention also includes a rigging system comprising a plurality of percolating boxes according to the invention. All embodiments of the percolation boxes, as described above, can also be transferred to the percolating boxes of the trench system. In particular, the configuration according to the invention with receptacles for stabilizing elements also allows a number of particularly advantageous embodiments with regard to rigging systems.

Thus, it can be provided in a further development of the inventive idea that, in the case of a plurality of seepage boxes arranged one above the other, a connection of adjacent percolating boxes following each other in the vertical direction is realized by or in the receptacles, in particular consisting of a plurality of partial stabilization elements stabilizing element and / or inserted into the receptacles connecting member , With particular advantage, therefore, there is also a stabilizing element which also passes through several, in particular all horizontal, layers of percolating boxes, which then not only serves to increase the load capacity of the trench system, but also connects overflowed percolating boxes. However, this need not be the case; it is also conceivable to connect special connecting components, for example shorter variants of the stabilizing elements, which protrude a short distance from the end sides of the percolating boxes into the receptacles, for example up to a blocking element. Finally, it is also conceivable that the stabilizing elements are formed, for example slightly longer than the Versickerbox, thus survive above. There, they can protrude into the corresponding receptacle of the next percolation box, again, for example, as far as a blocking element, and thus permit a connection of the percolating boxes which is in particular free of displacement. In the case of a stabilizing element composed of a plurality of sub-rods and passing through a plurality of percolating boxes, it can be provided with particular advantage that the connecting regions of the sub-stabilizing elements are arranged offset to the planes separating the two percolating boxes, in particular also offset from the assembly planes of the at least two structural bodies of a percolating box. Also in this way the stability is advantageously increased. If, for example, rods are provided as stabilizing elements, sub-rods can be inserted into one another, for example by round receptacles formed on the head surface of a partial rod, into which extensions of smaller diameter formed on the foot side of a partial rod can be inserted. In particular, a clamp-type press mount can also be provided, for example by profiling.

As already indicated in the discussion of the Versickerbox, it is particularly expedient if, furthermore, connecting elements are provided for connecting at least two horizontally adjacent percolating boxes, in particular at the level of the assembly plane to be arranged, flat, recesses for the stabilizing elements of adjacent Versickerboxen having connecting elements and / or in special receptacles for fasteners or appropriately designed receptacles for a stabilizing element usable, optionally also recesses for a stabilization sierungselement having connecting elements. The examples already mentioned with regard to the percolating box can be transferred here accordingly; in particular, it is also conceivable to connect four boxes to one another with connecting elements to be arranged in the corner regions.

Further advantages and details of the present invention will become apparent from the embodiments described below and with reference to the drawings. Showing:

1 shows an inventive percolation box 1. It comprises two identical structural bodies 3 which are combined to form a horizontal assembly plane 2, each having an open, three-dimensional and inherently stable structure. Both structural body 3 are substantially U-shaped and made of an injection-molded plastic, here polypropylene. As a result of the U-shaped design of the structural body 3, a substantially round through-passage 4 results centrally with a mirror-symmetrical composition, as shown in FIG. 1.

The lattice-like, three-dimensional structure apparently composed of grid elements, cross connections, struts, columns and the like can be seen to be at least partially fluid-permeable and essentially hollow but nevertheless fundamentally supporting. Possibilities for the specific embodiment of such structures are well known from the prior art and need not be detailed here. Apparently already forms the Versickerbox 1 alone a viable construct. For connection of the two structural bodies 3, insertion or engagement elements indicated at 5 may be provided. As can be seen, the percolation box 1 now has ten receptacles 6 passing through both structural bodies 3, which extend in the vertical direction, that is to say perpendicularly to the plane of composition 2. These are, as will be explained in more detail later, formed for insertion of elongated stabilizing elements. The receptacles 6 can also be clearly seen in FIG. 2 which is best considered together with FIG. 1. By way of example, an inserted stabilizing element 7 in the form of a profile bar 8 is shown in FIG.

The receptacles 6 now have, as shown both in FIG. 1 and in FIG. 2, at their upper and lower end the receptacle horizontally passing through blocking elements 9, on which an inserted stabilizing element 7 can put on and is supported. As an alternative to the blocking elements 9, the receptacles 6 could also be provided with constricting projections on which the underside of the stabilizing element 7 can also be placed.

As a further support possibility for stabilizing elements 7 webs 10 to be recognized are provided in the longitudinal direction of the receptacles 6 in FIG. 2, which allow a clamping or pressing support of the stabilizing elements 7 in the receptacles 6. The webs 10 may, for example, have a thickness of three millimeters, while the wall of the stabilization element 7 may have a thickness of five millimeters, so that the webs 10 hold the stabilizing element 7 firmly in the receptacle. As an alternative or in addition to the webs 10, it is also possible to provide a combination of snap-in nose and depression, which is not shown here in more detail, and which makes it possible to mount the stabilizing element 7 in the receptacles 6.

It can be provided that in some of the receptacles 6, the webs 10 (and thus also the receptacles 6 themselves) have a step 11. Such a step 11 can be used, for example, to receive a connecting element for connecting two adjacent percolator boxes in a trench system, which will be discussed in more detail later. Of course, 6 may be provided for all recordings 6 such a level. A broadening of the diameter of the receptacle 6 adjacent to the assembly plane 2 can also serve to position the stabilizing element 7 if this has a further diameter in the center. As already explained, the percolation box 1 is inherently stable. However, there are applications in which a higher loading of the percolator box 1 is to be expected, which according to the invention can be made possible by the use of stabilizing elements 7. Stabilizing elements do not have to be used in all of the receptacles 6; this can be made dependent on which load is to be expected. In addition, different stabilizing elements 7 may be provided, which can accommodate different vertical forces acting.

An example is shown in the schematic diagram in FIG. 3, in which six stabilizing elements 7 in the form of profiled bars 8 are inserted into the percolation box 1. In each case lying in the corners shots 6 and the two middle shots 6 were occupied. By varying the number of stabilizing elements 7 and the nature of the stabilizing elements 7, the percolating box 1 can be adapted to a wide variety of requirements with respect to load capacity.

In general, it should be noted that the stabilizing elements 7 may consist of the same material as the structural bodies 3. However, another material is conceivable, in particular a harder material. In the present example, the profile bar 8 is made of glass fiber reinforced polypropylene.

As can be seen, the stabilizing elements 7 or profile bars 8 extend over the entire length between the blocking elements 9, are therefore substantially as long as the Versickerbox is high. When assembling the Versickerbox 1, for example, first the rods 8 are inserted into the lower structural body 3, whereupon the upper structural body 3 is placed. By the webs 10 and the locking elements 9 results in a very stable holder, which can absorb shear forces between the structural bodies 3 in particular.

4 shows an example of another form of a profiled bar 8 serving as the stabilizing element 7. Obviously, the profiled bar 8 also has webs 12 which extend along its longitudinal direction and serve for an improved clamping or press mounting. In addition, the profile bar 8 has a collar 13, which serves for further stable positioning of the profile bar 8. In the installed state, this is located at the level of the assembly plane 2 and rests on the region of the structural body 3 surrounding the receptacle 6. Fig. 5 shows in cross section the profile of the profiled bar 8. This comprises an outer tube 14 and an inner tube 15 and five radially extending connecting walls 16. Similarly, the webs 12 can be seen. Due to the inner profile, the Beulfestigkeit the profile bar 8 is increased, which further contributes to the stability of the Versickerbox 1.

Before the rigging system according to the invention is to be discussed with reference to FIG. 7, it should initially be noted that the blocking elements 9 can be formed at least partially, for example also only for a part of the receptacles, also breakable, as shown by way of example in FIG a view of a structural body 3 of a Versickerbox invention 1 represents. As can be seen, the blocking elements 9 are connected only by thin webs 17, which are thin in the horizontal direction, with the inner boundary 18 of the receptacle 6, so that the blocking element 9 can be broken out. This may be useful, on the one hand, when the structural body 3 is already placed on the other structural body 3 and only then should the stabilizing elements 7 be introduced into the receptacles 6 from above.

Particular advantages of such breakable locking elements 9 arise with respect to the now discussed with regard to FIG. 7 Rigolensystems invention 19 There are four Versickerboxen 1 of the rig system 19 shown by way of example, which are arranged in two different layers of the rig system 19, so that in each case two of the here shown Versickerboxen 1 are stacked on top of each other. In order to improve the overall stability and connection of overflowing percolating boxes 1, continuous stabilizing elements 7 consisting of several partial stabilizing elements 20 are now inserted in the receptacles 6, this means that the stabilizing elements 7 are received in the continuous receptacles 6 of two percolating boxes 1. The partial stabilization elements 20, in this case part rods, essentially comprise one third of the length of a percolation box 1 and are composed. In this case, the connecting regions 21 of the partial stabilizing elements 20 are arranged so as to be offset relative to the assembly planes 2 of the percolating boxes 1 and the plane 22 separating two percolating boxes 1. In this way, a further shear stability is given. In Fig. 7, two embodiments of connecting elements 23 and 24 are additionally shown as part of the trench system 19, with which horizontally adjacent percolating 1 can be connected for further stabilization. In this case, the connecting element 23 is arranged at the level of a corner of the percolation box and substantially square. It has four recesses 25 through which the respective stabilizing elements 7 can be guided. In this way, four adjacent percolation boxes 1 can be connected non-displaceably. The recesses are ideally adapted to fit the stabilizing elements 7. In the exemplary illustration, a simpler connecting element 24 connects two horizontally adjacent percolating boxes 1, in that it comprises two loops 26, of which one each wraps around a stabilizing element 7.

Incidentally, each of the connecting elements illustrated here advantageously also consists of the same material as the percolating boxes 1, in this case, therefore, of polypropylene.

It can be seen here that the blocking elements 9 are not provided flush with the bottom surface or top surface of the seepage boxes 1, but a free part 27 of the receiver 6 remains even when a stabilizing element 7 is inserted For connection of the versifier boxes 1, a connecting component 28, which substantially corresponds to a shortened stabilizing element 7, can now be used.

Another conceivable possibility, not shown here, is also to provide no blocking elements 9 at the top of the percolating boxes or to break them out, so that the stabilizing element 7 can survive and be inserted into the free part 27 of the receptacle 6 of the overlying percolating box provided on the underside can be.

9 shows a further embodiment of a connecting element 29 for connecting two horizontally adjacent percolation boxes 1. The connecting element 29 comprises two short tube pieces 30, which are connected by a flat collar 31, which comes to lie in the assembled plane 2 in the installed state. The length of the tubes 30 is adjusted so that they come to rest on the steps 11 shown in Fig. 2 in the receptacles 6 and thereby a further stability is given. The tubes 30 thereby form recesses 25 through which the respective stabilizing element 7 is to be guided. Finally, FIG. 10 shows a further embodiment of a structural body 3 for forming a percolation box according to the invention. The structure of this structural body 3 is simpler in design and, in addition to the receptacles 6 formed by pipes, fits a three-dimensionally structured grid-like bottom plate 32, side grilles 33 and substantially U-shaped front and rear grilles 34, which in turn allow the formation of a through-channel 4.
