Abstract

The body has two grid body parts (10) e.g. grid plate elements, comprising two groups of grid bars (14, 16) that run parallel to each other and form a grid. The grid bars run relative to a layer (22) stretched from the grid body parts at an acute angle greater than 50-65 degrees or an angle greater than 115 degrees. One of the grid body parts comprises a connecting element in a form of complementary, interlinking connection projections and recesses (28, 34), where the connecting element is co-acted with the other grid body part. The grid body parts include a circumferential edge bar (12).

Description

The invention relates to an installation body for a device for the treatment, cooling or storage of a fluid, such as a gas or a liquid. For example, the installation body can be used in the soil as a drainage or drainage device. Another possible application of the installation body in the soil concerns the stabilization of near-surface soil zones, possibly with the possibility of treatment of accidentally or as expected reached the soil pollutants. In such an application, for example, the installation body is plantable, i. filled with soil or special mixtures of inorganic and organic mixtures for retention and purification of the incoming fluid and serves u.a. also the inclusion of loads on traffic areas. Finally, the installation body according to the invention may also be used as a trickle, immersion or trickling filter in trickle coolers, biological reactors or the like, such as gas scrubbers, as internals in cooling towers or as sedimentation aids in the form of slanted or lamellar clarifiers and / or precipitators in settling tanks (of eg sewage treatment plants).

Mounting body for the aforementioned uses are known in principle. As an example, be on EP-A-1 607 534 . EP-A-2 116 648 . EP-A-2 208 823 and EP-A-2 325 404 directed. Out EP-A-1 607 534 It is known in the width and height of different size grid boxes to produce by assembling grid box-one-piece parts. Such constructions can be basically also in EP-A-2 325 404 realize. In contrast, the other two aforementioned publications disclose grid bodies which are arranged exclusively next to one another in order to be adapted to the conditions of the installation site.

Out DE-U-20 2006 008 981 is a seepage and drainage body of individual disc or plate-shaped system elements known. A similar concept is also in, for example DE-U-10 2009 052 724 described. In the two last-mentioned publications, a plurality of disc-shaped or plate-shaped system elements are stacked on top of one another, wherein a plurality of such stacks can be arranged next to one another.

The object of the invention is to provide a mounting body, in particular for the aforementioned applications, which ensures increased stability by load distribution as possible within the grid system and improved variability in the size of the overall arrangement.

• einem ersten Gitterkörper, der eine erste Gruppe und eine zweite Gruppe von sich kreuzenden, innerhalb der jeweiligen Gruppen zueinander parallel verlaufenden Gitterstreben aufweist, die ein Raster bilden, und
• mindestens einem zweiten Gitterkörper, der ebenfalls eine erste Gruppe und eine zweite Gruppe von sich kreuzenden, innerhalb der jeweiligen Gruppe zueinander parallel verlaufenden Gitterstreben aufweist, die ebenfalls ein Raster bilden,
• wobei die Gitterstreben der ersten Gruppe der ersten und zweiten Gitterkörper relativ zu der von dem jeweiligen Gitterkörper aufgespannten Ebene unter einem spitzen, insbesondere bis zu 65° großen, Winkel bzw. einem stumpfen, insbesondere mehr als 115° großen, Winkel verlaufen.

To solve this problem, an installation body is proposed with the invention, which is provided with

• a first grid body having a first group and a second group of intersecting, within the respective groups mutually parallel grid struts forming a grid, and
• at least one second grid body, which likewise has a first group and a second group of intersecting grid struts running parallel to one another within the respective group, which also form a grid,
• wherein the lattice struts of the first group of the first and second lattice bodies extend at an acute, in particular up to 65 °, angle or an obtuse, in particular more than 115 °, large angle relative to the plane defined by the respective lattice body.

The installation body according to the invention can be modular and, depending on the desired installation size, composed of a plurality of substantially identical grid bodies, which are advantageously grid plates. These grid bodies can be stacked on top of one another, offset from each other and thus interleaved. Through this constellation built body in the desired shapes and dimensions.

The mounting body thus has at least two grid body, in the simplest Case are stacked on top of each other or arranged side by side. Each grid body has first and second intersecting grid struts. In this case, the first lattice struts are arranged substantially parallel to one another, while on the other hand the second lattice struts are likewise arranged running parallel to one another. The lattice struts cross each other and form a lattice structure with a grid. The grids of both grids may be the same or unequal; In particular, the grid of one grid body can be a multiple of the grid of the other grid body.

According to the invention, the first (and / or the second) lattice struts are now inclined, thus extending at an acute angle to the normal of the plane spanned by the lattice body. In other words, these first (and / or second) grid struts extend at an acute or obtuse angle to the plane spanned by the grid body. The angle to the normal is preferably between 25 ° and 40 °.

Such a designed grid body can be assembled as an installation body for a variety of uses specified above. The stack height of the grid body is basically arbitrary. The grid body can be made in particular of plastic, which z. B. injection molding technology can be done.

Stacked or superimposed grid bodies (for example, in that an upper grid body extends over the interface between two adjacent lower grid bodies) may advantageously be provided with cooperating connecting elements (and optionally additional centering aids) in the form of complementary, interlocking connecting projections and recesses. The connecting elements which can be brought into engagement with one another can be guided into one another in a non-positive or positive manner or by friction. The fasteners provide a strong and stable bond and also contribute to the shear stiffness of the body.

In a further advantageous embodiment of the invention, the lattice struts of the second group of grid body may extend substantially perpendicular to the plane defined by the respective grid body level. Thus, then the lattice struts of one of the two groups are tilted.

The grid body or each grid body may have a peripheral edge web, which is continuously formed continuously or is provided with interruptions. This edge web may have one or more edge portions in which it is perpendicular to the plane spanned by the grid body, and moreover have other edge webs which are as inclined as the lattice struts of the one of the two groups.

As already mentioned above, therefore, one of the lattice struts (for example the first lattice struts) is inclined between adjacent second lattice struts, with which they intersect. The lattice struts, which are formed as flat material elements, then define an oblique plane, but which has a structured surface and in particular complementary structured surfaces (top and bottom sides). The structured surfaces may be closed or perforated, thus themselves form a network structure. Such an installation body can be used in particular wherever it is necessary to keep the flow resistance for the medium to be treated as low as possible and to save material.

The adjacent grid bodies may be arranged such that their oblique grid struts complement the grid body stack by passing parallel oblique walls, which may optionally be perforated. Such an installation body can be used as a settling aid. Alternatively, it is possible that the oblique grid struts of adjacent grid body alternately oblique, ie zigzag-like (viewed in side view).

Due to the lattice structures, the intersecting lattice struts define chambers or the like. Breakthroughs or fields that are rhomboid or rectangular in plan view. Depending on the number of groups of intersecting lattice struts, it is also possible for chambers with other ground plan shapes to form. The invention is therefore not limited to only two lattice strut groups with mutually parallel lattice struts.

In a further advantageous embodiment of the invention may be arranged depending on the application between adjacent grid bodies spacers. Here, in the simplest embodiment, for example, offers a pin or otherwise strand-shaped component, which cooperates with the connecting elements, so that they can be used for receiving the spacers. In the simplest case, as a spacer pin or the like. Used pins, which are plugged onto a connecting projection of a lower grid body, and then placed on the spacer, the next upper grid body.

Adjacent grid bodies, which are arranged next to one another in a common plane, can be interconnected by mechanical connecting elements. This in turn contributes to shear stiffness of the built-in body.

As already mentioned above, can be "built" from the individual grid bodies mounting body for a variety of uses by multiple grid body are arranged one above the other or nested. A possible method for producing entire unit body blocks using the grid body according to the invention can be carried out as it is in WO 2009/153278 is described.

Fig. 1 shows in perspective a first embodiment of a grid body 10 with a circumferential upstanding edge web 12 and within the edge web 12 intersecting first lattice struts 14 and second lattice struts 16 which extend parallel to each other. The edge web 12 has two opposite first edge portions 18 and two likewise opposite second edge portions 20. The entire grid body 10 is formed as a grid plate and extends within a plane 22. Relative to this level 22, the two first edge portions 18 extend at right angles, while the two second edge portions 20 extend at an acute angle to the normal 24. This acute angle is for example 30 ° or slightly greater than 30 °. In other words, so are the second edge portions 20 at an angle of 50 ° -70 ° to the plane 22 (see Fig. 2 ).

Of the two lattice strut groups, one has the (first) lattice struts 14 and the other the (second) lattice struts 16. The first lattice struts 14 extend parallel to the first edge portions 18 and, like them, are substantially perpendicular to the plane 22. On the other hand, the second lattice struts 16 are inclined, as are the second edge portions 20 (see FIG Fig. 2 ).

To the top 26 of the grid body 10 protrude beyond these connecting projections 28 which are inclined as the second edge portions 20. Centering aids in the form of pins 30 which dip into corresponding openings (not shown) on the underside 32 of an adjacent grid body 10 are located on at least some of the crossing points of the lattice struts 14 and 16. Likewise, the connecting projections 28 dip into corresponding recesses 34 on the underside 32 of an adjacent grid body 10 (see FIG Fig. 2 ).

Fig. 3 shows in perspective and in exploded view two superimposed grid body 10,36. To construct an installation body several grid body are plugged together, in the form of a stack or else nested in one another. Fig. 4 shows in side view how two adjacent grid body 10,36 can be stacked. As can be seen from the above description, each grid body 10, 36 is sheared, so that when a built-up body is constructed from a plurality of such grid bodies 10, 36, a stack inclined to the side results. Such an installation body can, for example, as a settling aid in calming or settling tanks of sewage treatment plants or the like. or used in other bioreactors.

Fig. 5 shows a variant of the mounting body, as according to Fig. 4 or 3 is constructed. Here are adjacent grid body 10,36 offset in the X and / or Y direction to each other.

Such an arrangement of adjacent grid bodies 10,36 can also be used for transport purposes by the so interlocked grid body are arranged to save space.

As for example by Fig. 4 can be seen, the second lattice struts 16 are formed as inclined strips, which are the same width over their entire length. In contrast, the first lattice struts 14 in those areas in which they extend between adjacent second lattice struts 16, recesses 38. These recesses 38 may be formed on the upper side and lower side. In the same way, such recesses 40 are formed on the upper and lower sides, ie on the upper edge and the lower edge of the second edge sections 20.

In the FIGS. 6 and 7 an alternative embodiment of grid bodies 10 ', 36' is shown. The structure of each of these grid bodies 10 ', 36' corresponds, as far as the grid strut structure is concerned, substantially to that of the grid bodies 10 and 36 of FIG FIGS. 1 to 5 , The difference between the two grids 10 and 36 and 10 'and 36' is that in Fig. 6 the inclined second grid struts 16 are perforated and form a network structure of "finer" struts 42. In turn, the first lattice struts 14 extend at right angles to the plane 22 respectively spanned by the lattice bodies 10 'and 36'. The peripheral edge web 12 extends at right angles to the plane 22 in all of its edge sections 18, 20. The lattice bodies 10 ', 36' are, for example, one above the other stacked, with their inclined second lattice struts 16 alternately inclined and thus run in a zigzag-shaped side view and optionally have an offset with each other. The top, for example, of the grid body 36 'is thus on the top of the grid body 10', whereby the two grid body 10 'and 36' are rotated relative to each other and thus aligned differently, as in the embodiment of FIGS. 3 and 4 is shown. But also the grid body 10 'and 36' can, as the grid body 10 and 36 of the FIGS. 1 to 4 be composed. Then the sloping perforated second lattice struts 16 to form parallel perforated lattice walls.

The invention is not limited to the embodiments shown here and also includes other mounting body, which can be assembled with the grid bodies. Moreover, the invention also relates to a single grid body, ie an installation body comprising a single grid body.
