Definitions
- the invention relates to a plantable grid body for receiving traffic loads with a molding of mutually perpendicularly intersecting, provided with openings webs, which form at their respective opposite a transverse web projecting, opposite end faces grooves and springs for connecting further moldings.
- Grids for the attachment of traffic areas are generally cast from concrete, wherein recesses are provided in particular in the footprint of perpendicularly intersecting webs of the molding to moisture for the plantable chambers between the intersecting webs a moisture, ventilation and mass transfer between the chambers to enable. So that such grid body can be strung together easily, it is known ( DE 8600430 U1 ), to let project the webs of a crowd over the edge ridges of the other crowd and equip on opposite end faces with grooves and springs, so that when joining two grid bodies by half the distance between two parallel webs projecting end faces of the webs the chambers within the molding limit corresponding chambers.
- the disadvantage is that the tongue and groove joints between adjacent grid bodies can only prevent a mutual displacement of the grid body along the joint, but not an increase in distance in the longitudinal direction of the protruding webs or a mutual displacement of the grid of height.
- the invention is therefore the object of a grid body of the type described in such a way that it can be made of plastic, without having to accept losses in terms of load capacity.
- the invention achieves this object by virtue of the fact that the webs of the shaped plastic body are connected to one another by bottom sections in the region of the inner corners resulting between the intersecting webs, that the grooves of the webs have an undercut and the springs have a cross-sectional shape adapted to the undercut, and that on the opposite end faces of at least one web transverse, resilient projections are provided on the one hand with a latching recess and on the other hand with a latching projection.
- the compressive strength of the height-loaded webs is sufficient for this purpose even if openings must be provided in the webs to connect the chambers resulting between the webs in order to achieve the effect of an over the entire surface of the grid body continuous earth body.
- the contact surface of the grid body can be additionally enlarged.
- the bottom webs connecting the projecting end sides of the webs also entail an additional stiffening of the otherwise freely projecting end faces of the webs, which contributes to improved load transfer.
- grids with a single longitudinal ridge and a family of parallel transverse webs which form only in connection with subsequent moldings of the same education for planting certain receiving chambers may be given preference, result in grid body having a shaped body with two intersecting crowds Having parallel webs and thus form a plurality of receiving chambers for soil not only in connection with subsequent similar lattice bodies, advantages in terms of load transfer.
- a straight conclusion can be provided at the edges of the grid surfaces to be reinforced with grid bodies, can be connected to the protruding end faces at least on a peripheral side of the molding body, a closure wall which form cooperating with the grooves and springs of the webs spring and grooves.
- the end wall can thus in coincident with other grid bodies are attached to a marginal grid body, which can be achieved not only a conclusion of the reinforced bottom surface, but in addition a support of the otherwise freely projecting end faces of the webs.
- the moldings in the corner region of the intersecting webs pads for one of the webs enclosed by the chambers each final lid.
- the grid body according to the Fig. 1 and 2 has a molded body 1 made of plastic, which comprises a longitudinally extending web 2 and a crowd to transverse webs 3, which intersect the longitudinally extending web 2 at right angles and over this web 2 by half the distance between the parallel webs 3 opposite protrude the longitudinal web 2.
- the front sides of the longitudinally extending web 2 project by half the distance between two adjacent webs 3 with respect to the marginal webs 3, like the latter Fig. 1 can be removed.
- undercut grooves 4 and, on the other hand, springs 5 adapted to the cross section of these undercut grooves 4 are formed, in order to produce similar shaped bodies 1 both in the longitudinal direction and transversely thereto to be able to join one another in a form-fitting manner.
- the height-extending grooves 4 and 5 springs prevent no mutual displacement of the joined moldings 1 in the longitudinal direction of the grooves 4 and 5 springs. For this reason, an additional locking the height is provided.
- 2 or 3 transversely extending, resilient lugs 6 are provided on opposite end faces of at least selected webs, which are provided on the one hand with a latching recess 7 and on the other hand with a latching projection 8. If two moldings 1 of this type according to Fig. 3 and 4 joined together, the locking projections 8 engage in the recesses 7 of the lugs 6 of the respective subsequent webs 2, 3 and lock the two moldings 1 to form a structural unit. In order to facilitate the engagement of the locking projections 8 in the recesses 7 of the lugs 6 during insertion of the springs 5 in the grooves 4 of the webs 2, 3, at least the projection 6 with the recess 7 have a contact surface 9 for the locking projections 8, as of the Fig. 4 can be removed.
- the assembly forms between the intersecting webs 2, 3 chambers 10 for receiving soil. So that the soil is not in the individual Chambers 10 is completed, but together with the soil of the other chambers 10 forms a uniform for the fürwachsung, the liquid management, ventilation and nutrient exchange Erdenia, the webs 2, 3 in the region of the chambers 10 are provided with passages 11, as the Fig. 2 can be removed.
- the arrangement is made so that arise at a planting passage areas for both Flachwurzler and normal root and Tiefenwurzler. Due to the lattice shape of the molded body 1, the chambers 10 are also open at the bottom.
- the bottom-side end face of the webs 2, 3 result in a footprint that is too small for higher loads, so that such grid bodies would be pressed into the ground at higher loads.
- the footprint of the molded body 1 is enlarged by bottom portions 12 which connect the webs 2, 3 in the region of the intersecting between the intersecting webs 2, 3 inner corners. These bottom portions 12 increase the footprint of the molded body 1 considerably, without hindering the connection of the soil in the chambers 10 with the ground.
- the embodiment of a grid body according to the Fig. 4 and 5 is different from the one after the Fig. 1 and 2 essentially in that two mutually perpendicularly intersecting flocks of parallel webs 2, 3 are provided, wherein within the marginal webs 2 and 3, the chambers 10 result in receiving soil.
- the parallel orientation of the webs 2 and 3 should include a slight inclination of these webs for better removal of the forming between the webs 2, 3 chambers 10.
- the end faces of the webs 2, 3 are in turn on the edge-side web 3, 2 of the respective transversely extending web section before, by half the distance between adjacent webs 2 and 3.
- the moldings 1 can be positively connected with each other in a comparable manner.
- the resilient lugs 6, on the one hand latching recesses 7 and on the other hand latching projections 8 a latching also the height is possible when two grid body of this type are joined together.
- the footprint of this grid body is not only by the webs 2, 3 interconnecting bottom portions 12 increases, but also by edge-side bottom webs 13, which also bring an additional stiffening of the frontally projecting webs 2, 3 with it. This stiffening can be increased by stiffening ribs 14 between the bottom webs 13 and the webs 2, 3.
- the moldings 1 may have in the corner region of the intersecting webs 2, 3 supports 15 for one of the webs 2, 3 enclosed chamber 10 each final lid 16, as the Fig. 6 can be removed. If necessary, thus, the grid body can be provided with a closed surface.
- Fig. 7 can be connected to the edge end of a molded body 1, a closure wall 17 to the protruding end faces of the respective webs 2, via the provided end grooves 4 and springs 5.
- the end wall 17 is provided with corresponding springs 18 and grooves 19 so that the end wall 17 can be positively connected to the projecting webs 2 as a grid body.

Abstract
Description
Die Erfindung bezieht sich auf einen bepflanzbaren Gitterkörper zum Aufnehmen von Verkehrslasten mit einem Formkörper aus einander rechtwinkelig schneidenden, mit Durchtrittsöffnungen versehenen Stegen, die an ihren jeweils gegenüber einem quer verlaufenden Steg vorstehenden, einander gegenüberliegenden Stirnseiten Nuten und Federn zum Anschluss weiterer Formkörper bilden.The invention relates to a plantable grid body for receiving traffic loads with a molding of mutually perpendicularly intersecting, provided with openings webs, which form at their respective opposite a transverse web projecting, opposite end faces grooves and springs for connecting further moldings.
Gitterkörper zur Befestigung von Verkehrsflächen werden im Allgemeinen aus Beton gegossen, wobei Ausnehmungen insbesondere im Bereich der Aufstandsfläche der sich rechtwinkelig schneidenden Stege des Formkörpers vorgesehen werden, um für die bepflanzbaren Kammern zwischen den einander schneidenden Stegscharen einen Feuchtigkeits-, Belüftungs- und Stoffaustausch zwischen den Kammern zu ermöglichen. Damit solche Gitterkörper einfach aneinandergereiht werden können, ist es bekannt (
Es wurde außerdem vorgeschlagen (
Der Erfindung liegt somit die Aufgabe zugrunde, einen Gitterkörper der eingangs geschilderten Art so auszugestalten, dass er aus Kunststoff gefertigt werden kann, ohne Einbußen hinsichtlich der Belastbarkeit in Kauf nehmen zu müssen.The invention is therefore the object of a grid body of the type described in such a way that it can be made of plastic, without having to accept losses in terms of load capacity.
Die Erfindung löst die gestellte Aufgabe dadurch, dass die Stege des aus Kunststoff geformten Formkörpers im Bereich der sich zwischen den schneidenden Stegen ergebenden Innenecken miteinander durch Bodenabschnitte verbunden sind, dass die Nuten der Stege eine Hinterschneidung und die Federn eine an die Hinterschneidung angepasste Querschnittsform aufweisen und dass an den einander gegenüberliegenden Stirnseiten wenigstens eines Steges quer verlaufende, federnde Ansätze einerseits mit einer Rastausnehmung und anderseits mit einem Rastvorsprung vorgesehen sind.The invention achieves this object by virtue of the fact that the webs of the shaped plastic body are connected to one another by bottom sections in the region of the inner corners resulting between the intersecting webs, that the grooves of the webs have an undercut and the springs have a cross-sectional shape adapted to the undercut, and that on the opposite end faces of at least one web transverse, resilient projections are provided on the one hand with a latching recess and on the other hand with a latching projection.
Da die Stege miteinander durch Bodenabschnitte im Bereich der zwischen ihnen gebildeten Innenecken verbunden sind, ergibt sich eine durch diese Bodenabschnitte eine erheblich vergrößerte Aufstandsfläche für die Gitterkörper, die folglich höhere Auflasten auf den Untergrund abtragen können, ohne in den Untergrund eingedrückt zu werden. Dazu kommt, dass aufgrund der Hinterschneidungen im Nut-Federbereich über die vorstehenden Stirnseiten der Stege auch in Längsrichtung dieser Stege verlaufende Zugkräfte übernommen werden können, was im Zusammenwirken mit der Verrastung der Höhe nach eine Lastverteilung über mehrere miteinander verbundene Gitterkörper mit sich bringt, sodass trotz der Fertigung der Gitterkörper aus Kunststoff und der damit verbundenen vergleichsweise geringen Stegdicke auch schwerere Verkehrslasten ohne weiters aufgenommen werden können. Die Druckfestigkeit der der Höhe nach belasteten Stege reicht hiefür auch dann aus, wenn in den Stegen zur Verbindung der sich zwischen den Stegen ergebenden Kammern Durchtrittsöffnungen vorgesehen werden müssen, um die Wirkung eines über die gesamte Fläche der Gitterkörper durchgehenden Erdkörpers zu erzielen. In diesem Zusammenhang ist außerdem zu berücksichtigen, dass durch die Füllung der Kammern mit Erdreich die diese Kammern begrenzenden Stege gegen ein Ausknicken zusätzlich abgestützt werden.Since the webs are connected to each other by floor sections in the region of the inner corners formed between them, resulting through these bottom sections a considerably enlarged footprint for the grid body, which can thus remove higher loads on the ground, without being pressed into the ground. In addition, due to the undercuts in the tongue-spring area on the projecting faces of the webs extending in the longitudinal direction of these webs tensile forces can be taken, which in cooperation with the locking of the height according to a load distribution over a plurality of interconnected grid body brings with it, so that despite the production of the mesh body made of plastic and the associated comparatively small web thickness and heavier traffic loads can be taken without further. The compressive strength of the height-loaded webs is sufficient for this purpose even if openings must be provided in the webs to connect the chambers resulting between the webs in order to achieve the effect of an over the entire surface of the grid body continuous earth body. In this context, it should also be taken into account that the filling of the chambers with soil, the webs bounding these chambers are additionally supported against buckling.
Sind die Stege im Bereich ihrer vorstehenden Stirnseiten zumindest auf einer Seite des Formkörpers durch einen randseitigen Bodensteg miteinander verbunden, so kann die Aufstandsfläche des Gitterkörpers zusätzlich vergrößert werden. Die die vorstehenden Stirnseiten der Stege miteinander verbindenden Bodenstege bringen aber auch eine zusätzliche Versteifung der sonst frei vorragenden Stirnseiten der Stege mit sich, was zu einer verbesserten Lastabtragung beiträgt.If the webs are connected to one another in the region of their projecting end faces, at least on one side of the molded body, by a peripheral web of webs, then the contact surface of the grid body can be additionally enlarged. However, the bottom webs connecting the projecting end sides of the webs also entail an additional stiffening of the otherwise freely projecting end faces of the webs, which contributes to improved load transfer.
Obwohl aus Gründen der einfacheren Herstellbarkeit Gitterkörpern mit einem einzigen Längssteg und einer Schar von parallelen Querstegen, die erst in Verbindung mit anschließenden Formkörpern gleicher Ausbildung zum Bepflanzen bestimmte Aufnahmekammern bilden, der Vorzug gegeben werden kann, ergeben Gitterkörper, die einen Formkörper mit zwei einander schneidenden Scharen paralleler Stege aufweisen und folglich eine Mehrzahl von Aufnahmekammern für Erdreich nicht nur in Verbindung mit anschließenden gleichartigen Gitterkörpern formen, Vorteile hinsichtlich der Lastabtragung.Although for the sake of ease of manufacture grids with a single longitudinal ridge and a family of parallel transverse webs, which form only in connection with subsequent moldings of the same education for planting certain receiving chambers may be given preference, result in grid body having a shaped body with two intersecting crowds Having parallel webs and thus form a plurality of receiving chambers for soil not only in connection with subsequent similar lattice bodies, advantages in terms of load transfer.
Damit an den Rändern der mit Gitterkörpern zu verstärkenden Bodenflächen ein gerader Abschluss vorgesehen werden kann, kann an die vorstehenden Stirnseiten zumindest auf einer Umfangsseite des Formkörpers eine Abschlusswand anschließbar sein, die mit den Nuten und Federn der Stege zusammenwirkende Feder und Nuten bilden. Die Abschlusswand kann somit in übereinstimmender Weise mit anderen Gitterkörpern an einen randseitigen Gitterkörper angesetzt werden, wodurch sich nicht nur ein Abschluss der verstärkten Bodenfläche, sondern zusätzlich eine Abstützung der sonst frei vorragenden Stirnseiten der Stege erreichen lässt.So that a straight conclusion can be provided at the edges of the grid surfaces to be reinforced with grid bodies, can be connected to the protruding end faces at least on a peripheral side of the molding body, a closure wall which form cooperating with the grooves and springs of the webs spring and grooves. The end wall can thus in coincident with other grid bodies are attached to a marginal grid body, which can be achieved not only a conclusion of the reinforced bottom surface, but in addition a support of the otherwise freely projecting end faces of the webs.
Bildet der federnde Ansatz zumindest mit der Rastausnehmung im Bereich des oberen Endes der Stirnseite des jeweiligen Steges eine Anlauffläche für einen Rastansatz, so wird die Verrastung der über ihre vorstehenden Stege miteinander verbundenen Gitterkörper erleichtert, weil beim Einführen der an den einen Stegen vorgesehenen Federn in die hinterschnittenen Nuten der anschließenden Stege die auf die Anlaufflächen aufgleitenden Rastvorsprünge das für den Rasteingriff erforderliche elastische Auseinanderbiegen der die Rastausnehmungen bzw. die Rastvorsprünge bildenden Stegansätze bedingen.Forms the resilient approach at least with the recess in the region of the upper end of the end face of the respective web a contact surface for a locking projection, the locking of the interconnected via their projecting webs grid body is facilitated because when inserting the provided on the webs springs in the undercut grooves of the adjoining webs on the stop surfaces sliding on the locking projections required for the locking engagement elastic bending apart of the locking recesses or the locking projections forming web approaches condition.
Zur allfälligen Abdeckung der sich zwischen den Stegen der Formkörper ergebenden Kammern können die Formkörper im Eckbereich der einander schneidenden Stege Auflagen für einen die von den Stegen umschlossenen Kammern jeweils abschließenden Deckel aufweisen.For possible covering of the resulting chambers between the webs of the moldings, the moldings in the corner region of the intersecting webs pads for one of the webs enclosed by the chambers each final lid.
