solution

The object is achieved by the percolation block element according to claim 1, the percolator block according to claim 13 and the transport unit according to claim 16. Preferred embodiments are disclosed in the dependent claims.

The percolating block element comprises a base wall having a base surface to which a plurality of hollow pillars are connected. The columns are designed and arranged such that in the case of two identical and identically aligned percolating block elements, the first columns of the first percolating block element can be introduced into the second columns of the second percolating block element and a stack of the two identical and identically aligned percolating block elements can be formed. The base wall includes column tip receptacles adapted to receive column tips. The perimeter block element has an axis symmetry of 180 ° or less when rotated about a rotational axis of symmetry that is perpendicular to the base surface of the base wall. The column tip receptacles and the columns are further designed and arranged such that when two identical and about a rotation axis perpendicular to the base surface of the base wall by 90 ° or less against each other arranged infiltration block elements, the column tips of the first blocker block element in the column tip receptacles of the second percolation block element can be introduced and an operating distance between a first underside of a first base wall and an upper side of a second base wall can be formed.

The edge length of the base wall can be 800 ± 200 mm and its thickness 40 ± 20 mm.

A stack of two or more percolating block elements allows a space-saving arrangement of percolating block elements by placing the columns of a percolating block element into the columns of a percolating block element arranged underneath. Such an arrangement of sintered block elements stacked in one another makes sense, for example, in the case of transport by truck from a production plant and / or a warehouse to a construction site, since this can optimize the space utilization on the truck.

There may be a clearance between a first underside of the first base wall and an upper surface of the second base wall when two percolating block elements are stacked, ie, when the first columns of the first percolator block are inserted into the second columns of the second percolator block. This so-called stack spacing can be 20 ± 20 mm, ie the stack spacing can also be 0 mm, so that one top side and one bottom side of two blocker block elements come to rest on one another.

The term operating distance refers to the distance between the first underside of the first base wall and the top of the second base wall, when two identical and arranged around the rotation axis by 90 ° or less against each other arranged infiltration block elements, the column tips of the first blocker block element in the column tip receptacles of the second percolation block element are introduced. This arrangement corresponds to that for operation as an underground water reservoir. The operating distance can be 354 ± 20 mm.

The column tips are located at the end of the columns facing away from the base wall. The column tips preferably have a smaller cross-section than the columns and are positively received or clipped by the column tip receptacles of the base walls. Thus, in an arrangement of the Sickerblock elements for the operation of a secure and stable connection of two Sickerblock elements without further aids possible. A column tip may have a length of 20 ± 10 mm.

The column tip receptacles in the base wall are advantageously designed to be continuous so that water can pass through the column tip receptacles, through the hollow columns and through openings in the columns and / or the column tips.

If the base area of the bead block element is square, then the bead block element can have an axis symmetry of 180 ° when rotating about the rotational symmetry nose. An operating distance between two blocker elements can be formed when two identical and about an axis perpendicular to the base surface of the base wall axis of rotation are arranged rotated by 90 ° from each other. In the case of block elements with a square base, the rotational axis of symmetry and the axis of rotation are identical. The rotational symmetry axis or the axis of rotation passes through the intersection of the two 45 ° diagonals of the base surface of the base wall and extends perpendicular to the base surface.

If the base surface of the bead block element is rectangular, then the bead block element can have an axis symmetry of 180 ° when rotating about the rotational symmetry axis, wherein the rotational symmetry axis runs perpendicular to the base surface of the base wall and can pass through the intersection of the two diagonals of the base surface. The column tip receptacles and the pillars of the Sickerblockelements with rectangular base can be designed and arranged so that when two identical and about a perpendicular to the base of the base wall axis of rotation rotated 90 ° against each other arranged block filter elements, the column tips of the first block filter element, ie the upper Seeperblockelements, in the column tip shots of the second blocker block element, ie the lower blocker block element, can be introduced and an operating distance between the first underside of the first base wall and the top of the second base wall is formed. Depending on the arrangement of the columns and the column tip shots, the rotational axis of symmetry and the axis of rotation may be the same or different.

If the base area of the bead block element is hexagonal, then the bead block element can have an axis symmetry of 180 °, 120 ° or 60 ° when rotating about the rotational symmetry nose. Depending on the arrangement of columns and column tip shots, an operating distance between two blocker elements with a hexagonal base area can be achieved if two identical block elements are arranged rotated by 60 ° relative to one another about the base surface of the base wall axis of rotation. For a hexagonal base block, the rotational axis of symmetry and the axis of rotation are generally the same.

If the base surface of the bead block element is formed octagonally, the bead block element can have an axis symmetry of 180 °, 135 °, 90 ° or 45 ° when rotating about the rotational symmetry nose. Depending on the arrangement of columns and column tip recordings, an operating distance between two blocker elements with an octagonal base can be achieved if two identical block elements are arranged rotated by 90 ° or 45 ° relative to each other about an axis perpendicular to the base surface of the base wall. In the case of a perimeter block having an octagonal base, the rotational axis of symmetry and the axis of rotation are generally the same.

The columns may be substantially conical. This essentially means the outer shape of the columns. Since the pillars are hollow, the inner shape may correspond to the outer shape taking into account the wall thickness (for example, 3 ± 1 mm). But it can also be provided that the inner mold and the outer shape of the column do not correspond to each other. A cone or an approximate cone may end in the region of the column tips - that is, a truncated cone or a truncated, approximate cone, so that the column tips protrude from the truncated cone. If the cross section of the column tips is smaller than the cross section of the truncated cone or of the truncated, approximate cone, a step is formed. The conical or approximately conical shape offers good stability and allows the block of block elements to be stacked one inside the other.

It can be provided that the columns have a round, an oval or a polygonal cross-section. It can also be provided that the columns have a cross section with a wavy edge.

The columns may each comprise at least one opening. The at least one opening allows water to pass through these at least one opening and through the hollow columns at one end of which are the column tips. Through the at least one opening thus water can get into a arranged below it Sickerblock element and / or the soil. The at least one opening may be arranged on the side surface of a column, in the step and / or in the column tip.

The base wall may comprise a rib structure. The rib structure allows passage of water while also providing required stability of the percolator element when buried in the ground.

The column tips may have a smaller cross-section than the columns, so that in each case a step is formed on an underside of the column. The column tip receptacles of the base wall and / or the receptacles of the bottom plate and / or the recesses of the transport plate may be formed respectively contrary to the shape of the column tips and the steps, so that at identical and each rotated about the rotation axis by 90 ° or less against each other arranged Sickerblock elements the column tips of a Sickerblockelements can positively engage in the column tip recordings or the recordings of the bottom plate or the recesses of the transport plate. Due to the shape of the column tips can also be done centering in the column tip recording.

The inner sides of the columns can each comprise a projection which is designed and arranged such that in the case of two identical and identically aligned block elements, the steps can be introduced in a form-fitting manner into the projections. Thus, it can be avoided in a transport of multiple stacked blocker elements that the individual block elements move against each other and it comes during transport damage and / or signs of wear. In addition, a wedging of the Sickerblockelemente can be avoided.

The bead block element can be formed from at least one plastic molding. It can be recycled plastic. The percolating block elements thus combine the advantages of a comparably low weight and great stability.

The columns may be integrally connected to the base wall. This has the advantage that the base wall and columns can be produced in one casting operation and that subsequent assembly of the individual columns on the base wall is not required.

Detailed description of the figures

FIG. 1 shows two blocker blocks 1, each having a base wall 2 with a square base, with a plurality - here 34 pieces - is connected by hollow columns 3. The columns 3 are conically formed with an oval cross-section and have at the end facing away from the base wall 2 each have a column tip 5. A perimeter block element 1 has an axis symmetry of 180 ° when rotating about the rotational axis of symmetry A1 of the base area, wherein the rotational axis of symmetry A1 runs perpendicular to the base area of the base wall 2 and passes through the intersection of the two 45 ° diagonals DI1, DI2 of the base wall 2. The columns 3 are arranged such that they are mirror-symmetrically arranged with respect to both center lines M1, M2 of the base wall 2 and with respect to both 45 ° diagonals DI1, DI2 of the base wall 2 is not mirror-symmetrical. When mirroring at the two 45 ° diagonals DI1, DI2 of the base wall 2 comes at the position of a column 3, a column tip recording 4 or at the position of a column tip recording 4 a column 3 to lie (see also FIG. 2 ). This results - as in connection with the Figures 5 and 6 explained in more detail - a symmetrical load entry at two or more superimposed, in each case by 90 ° about the axis of rotation A, which here corresponds to the rotational axis of symmetry A1, the base turned twisting block elements.

In FIG. 1 is the upper blocker block element 1 with respect to the lower block filter element rotated by 90 ° about the axis of rotation A of the base. The base walls 2 comprise Column tip receptacles 4 adapted to receive column tips 5 of the columns 3.

The same applies in the case of a reflection at the other 45 ° diagonal DI1 of the base wall 2.

FIG. 3 shows a plan view of the bottom 2b of a percolation block element 1, wherein the hollow columns 3 extend with the oval cross-section perpendicularly from the bottom 2b of the base wall 2 away. The column tips 5 have a through opening 9, which allow passage of water through this opening 9 and the hollow columns 3.

The FIGS. 2 and 3 illustrate that the column tip shots 4 and the columns 3 are formed and arranged such that with two identical and about the rotation axis A rotated by 90 ° against each other arranged Sickerblock elements 1, the column tips 5 of the upper Sickerblockelements 1 in the column tip shots 4 of the lower Sickerblockelements 1 can be introduced or that in two identical and identically aligned Sickerblockelementen 1, the columns 3 of the upper Sickerblockelements 1 in the columns 3 of the lower Sickerblockelements 1 can be introduced.

FIG. 4 shows the composite elements of the FIG. 1 ie, the two percolating block elements 1 and the bottom plate 6. An operating distance D1 results between the underside 2b of the upper base wall 2 and the upper side 2a of the lower base wall 2. Between the bottom 2b of the lower base wall 2 and the top 6a of the bottom plate 6 results in a distance D2, wherein D1 is equal to D2.

FIG. 5 shows a sectional view of FIG. 4 along BB. The column tips 5 with the openings 9 of the upper block filter element 1 engage in the column tip receptacles 4 of the lower block filter element 1, and the column tips 5 with the openings 9 of the lower block block element 1 engage in the receptacles 7 of the bottom plate 6.

The columns 3 are, as already mentioned, arranged such that they are mirror-symmetrically arranged with respect to both center lines M1, M2 of the base wall 2 and with respect to both 45 ° diagonals DI1, DI2 of the base wall 2, wherein in a mirror to the both 45 ° diagonals DI1, DI2 of the base wall 2 at the position of a column 3, a column tip receptacle 4 or at the position of a column tip receptacle 4 a column 3 comes to rest. This allows for identical and in each case about the rotation axis A by 90 ° turned against each other arranged Sickerblock elements 2 a symmetrical load entry. The sectional view of FIG. 5 and the cutting magnification of the FIG. 6 make it clear that the force is transferred from a column 3 of the upper blocker block element 1 evenly to two columns 3 of the underlying blocker block element 1, since the column tip holder 5 for the upper column 3 on the surface 2a of the base wall 2 of the underlying blocker block element 1 in the area is arranged between two columns 3 of the underlying blocker block element 1.

FIG. 6 shows along a vertical plane the line of the wall 18 (solid line) of a first column 3 of the upper base wall 2 starting from a first location, to which the first column 3 and a first column tip holder 4 of the upper base wall 2 directly adjoin, to the upper side 2a of the lower base wall 2, where the first column tip 5 of the first column 3 is inserted into a second column tip holder 4 of the lower base wall 2 is and from there to the line of the wall 19 (solid line) of a second column 3 of the lower base wall 2, starting from a second location at which the second column 3 and the second column tip receptacle 4 of the upper base wall 2 directly adjoin, so shows that this line of the wall 18 of the first column 3 and the wall 19 of the second column 3 is merging into each other.

Accordingly, the line of the wall 20 (dashed line) of the first pillar 3 and the wall 21 (dotted line) of the second pillar 3 is merged with each other. Along a vertical plane, the line of the wall 20 of the first column 3 of the upper base wall 2 is shown starting from a first position at which the first column 3 and a third column tip receptacle 4 of the upper base wall 2 are directly adjacent to each other lower base wall 2, where the first column tip 5 of the first column 3 is inserted into the second column tip receptacle 4 of the lower base wall 2 and from there to the line of the wall 21 of a third column 3 of the lower base wall 2 starting from a third location, at the third column 3 and the second column tip receptacle 4 of the upper base wall 2 directly adjacent.

The forces acting from the first column 3 of the upper base wall 2 to the columns 3 of the lower base wall 2 are represented by two arrows 22, 24. The one part of the force 22 thus passes to the second column 3 of the lower base wall 2, represented by the arrow 23, and the other part of the force 24 passes to the third column 3 of the lower base wall 2, represented by the arrow 25th

FIG. 7 shows an oblique view of the bottom plate 6, the lower blocker block element 1 and cut off in the region of the columns 3 upper percolating block element 1 in order to represent the positions of the columns 3 of the upper percolation block 1 relative to the lower percolating block element 1 more clearly.

FIG. 8 shows a side view of twenty stacked blocker block elements 1. This stacking option results from the fact that the columns 3 of the blocker block elements 1 are designed and arranged so that with identical and identically aligned Sickerblockelementen 1, the columns 3 of an above arranged Sickerblockelements 1 in the columns 3 one below arranged Sickerblockelements 1 can be introduced. Between a bottom 2b of a base wall 2 arranged above and a top 2a an underlying base wall 2 results in the representation of a stack spacing D3.

The nested block block elements 1 are arranged on a transport plate 10, which has feet 11 on its underside 10b, so that, for example, the fork of a forklift can be introduced under the transport plate 10. On the top 10a, the transport plate 10 recesses 12, in which the column tips 5 of a Sickerblockelements 1 can be introduced. Between the bottom 2b of the base wall 2 and the top 10a of the transport plate 10 results in a distance D4, wherein in general D4 is equal to D1 and equal to D2. The in the FIG. 8 shown arrangement of a plurality of sintered block elements 1 stacked in one another, which are arranged on a transport plate 10, may be referred to as a transport unit.
