Description

Die Erfindung betrifft einen Pfosten der im Oberbegriff des Anspruchs 1 angegebenen Art sowie ein Verfahren zur Herstellung.The invention relates to a post of the type specified in the preamble of claim 1 and a method for manufacturing.

Derartige Pfosten sind bekannt und werden insbesondere zur Verankerung von Kinderspielgeräten an Abenteuerspielplätzen verwendet.Such posts are known and are used in particular for anchoring children's play equipment to adventure playgrounds.

Die bekannten Klettergerüste, Schaukeln und dergleichen aus Holz neigen nach einiger Zeit insbesondere bezüglich der im Erdreich angeordneten Pfostenteile zum Verrotten. Eine Oberflächenbeschichtung und/oder eine Imprägnierung der Pfostenhölzer kann diesen Prozeß verlangsamen. Es werden deshalb kesseldruckimprägnierte Holzpfosten seit längerem als Verankerungselemente verwendet.The well-known climbing frames, swings and the like made of wood tend to rot after some time, in particular with regard to the post parts arranged in the ground. Surface coating and / or impregnation of the post wood can slow this process down. For this reason, wooden posts impregnated with boiler pressure have long been used as anchoring elements.

Inzwischen hat man aber festgestellt, daß Imprägniermittel mit der Zeit aus dem Holz ausgewaschen werden. Um gesundheitliche Gefahren zu vermeiden, wird deswegen im zunehmenden Maße nur noch eine Verwendung von nicht imprägnierten Holzpfosten als Verankerungselemente für Kinderspielgeräte empfohlen oder sogar angeordnet. Nicht imprägnierte Hölzer sind aber für eine Erdverankerung wesentlich schlechter geeignet. Die im Erdreich verankerten Teile lassen sich schlecht kontrollieren bzw. nachbehandeln. Bei zusätzlichem Insektenbefall kann es zu vorzeitigen Faulungsprozessen kommen, wodurch die Standsicherheit der Pfosten weiter herabgesetzt ist und eine Unfallgefährdung der Kinder besteht.In the meantime, however, it has been found that impregnating agents are washed out of the wood over time. In order to avoid health hazards, the use of non-impregnated wooden posts as anchoring elements for children's play equipment is increasingly recommended or even ordered. Non-impregnated woods are much less suitable for ground anchoring. The parts anchored in the ground are difficult to control or treat. With additional insect infestation, there can be premature digestion processes, which further reduces the stability of the posts and puts the children at risk of accidents.

Der Erfindung liegt die Aufgabe zugrunde, einen Pfosten zur Verankerung von Kinderspielgeräten zu schaffen, welcher in seinen Eigenschaften hinsichtlich der Verrottungsbeständigkeit Pfosten aus Holz überlegen ist, im übrigen aber dem Pfosten aus Holz gleichwertig ist.The invention has for its object to provide a post for anchoring children's play equipment, which is superior in its properties in terms of rot resistance wooden post, but is otherwise equivalent to the wooden post.

Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved with the characterizing features of claim 1.

Die Erfindung beruht auf der Erkenntnis, daß der Pfosten mindestens zweiteilig ausgebildet ist und daß der in das Erdreich einzubringende Teil des Pfostens aus Kunststoff, insbesondere Recycling-Kunststoff, besteht und mit einem Pfostenteil aus Holz, insbesonders nicht imprägniertem Holz, verbunden ist. Die Verbindung wird mittels Profile, vorzugsweise aus Hartmetall, insbesondere Eisen, hergestellt, da diese zur Schaffung einer stabilen Verbindung zwischen Kunststoff-und Holzelementen unterschiedlichster Beschaffenheit hinsichtlich Material und/oder Querschnittsform geeignet sind.The invention is based on the knowledge that the post is formed at least in two parts and that the part of the post to be introduced into the ground is made of plastic, in particular recycled plastic, and is connected to a post part made of wood, in particular non-impregnated wood. The connection is made by means of profiles, preferably made of hard metal, in particular iron, since these are suitable for creating a stable connection between plastic and wooden elements of the most varied nature in terms of material and / or cross-sectional shape.

In einer bevorzugten Ausführung des Pfostens wird eine stabile und zugleich sichere Verbindung, mit einem, in einer Aussparung in den Stirnflächen der Kunststoff- und Holzelemente, angeordnetes Verankerungsprofil hergestellt. Durch mindestens eine Querbohrung im Verankerungsprofil kann das Verankerungsprofil fest mit dem Holzelement verbunden und verriegelt werden. Das Holzelement weist mindestens eine Bohrung auf, welche an den Enden konisch aufgeweitet ist. In diese Bohrung wird eine Schraube eingeschraubt wobei sie durch die Querbohrung im Verankerungsprofil geführt wird. Eine Verschlußkappe deckt die konisch aufgeweitete Bohrung an der Oberfläche des Holzelements ab. Dadurch wird die von der Verschraubung ausgehende Verletzungsgefahr gemindert und die Verbindung zwischen Kunststoff- und Holzelement ist nicht sichtbar.In a preferred embodiment of the post, a stable and at the same time secure connection is produced, with an anchoring profile arranged in a recess in the end faces of the plastic and wooden elements. The anchoring profile can be firmly connected to the wooden element and locked by at least one cross hole in the anchoring profile. The wooden element has at least one hole which is flared at the ends. A screw is screwed into this hole and is guided through the cross hole in the anchoring profile. A cap covers the flared hole on the surface of the wooden element. This reduces the risk of injury from the screw connection and the connection between the plastic and wooden element is not visible.

Das Verankerungsprofil besteht vorzugsweise aus einem Eisenwerkstoff, wie St37, und kann beispielsweise als Rundstange oder als Flacheisen ausgebildet sein. Die Breite des Flacheisens kann entweder mit der Breite der zu verbindenden Kunststoff- und Holzelemente übereinstimmen oder kleiner sein, so daß das Flacheisen nicht an der Oberfläche in Erscheinung tritt. Die Aussparungen werden beispielsweise in die Holz- und Kunststoffelemente gefräst oder gebohrt. Das Verankerungsprofil wird bevorzugt mit dem Kunststoffelement verklemmt, verschraubt oder verklebt.The anchoring profile preferably consists of an iron material, such as St37, and can be designed, for example, as a round bar or as a flat iron. The width of the flat iron can either match the width of the plastic and wooden elements to be connected or be smaller, so that the flat iron does not appear on the surface. The recesses are milled or drilled in the wood and plastic elements, for example. The anchoring profile is preferably clamped, screwed or glued to the plastic element.

Das Verankerungsprofil wird vorzugsweise vor der Einbringung in das Kunststoffelement erwärmt und dann in die Aussparung, die vorzugsweise einen kleineren Querschnitt als das Verankerungsprofil aufweist, eingepreßt. Es ist auch günstig, den unteren, im Kunststoffelement einzubringenden Teil eines Verankerungsprofils direkt in ein Kunststoffelement ohne Aussparung einzupressen oder während der Herstellung des Kunststoffelements einzugiessen. Das Kunststoffelement kann im letzteren Fall schon werkseitig mit dem Verankerungsprofil verbunden werden, so daß sich auf diese Weise der Montageaufwand am Standort verringert. Unabhängig von der Einbringungsart ist die Verbindung, die durch das Schmelzen und die nachfolgende Aushärtung des Kunststoffs im Bereich des Verankerungsprofils entsteht, belastbar und sicher. Der obere, im Holzelement einzubringende Teil des Verankerungsprofils weist mindestens eine Querbohrung auf. Diese Querbohrung kann mit einem Gewinde versehen werden, um die Festigkeit der Verbindung in vorteilhafter Weise weiter zu erhöhen.The anchoring profile is preferably heated before being introduced into the plastic element and then pressed into the recess, which preferably has a smaller cross section than the anchoring profile. It is also favorable to press the lower part of an anchoring profile, which is to be introduced into the plastic element, directly into a plastic element without a recess or to cast it in during the production of the plastic element. In the latter case, the plastic element can already be connected to the anchoring profile at the factory, so that the assembly effort at the site is reduced in this way. Regardless of the type of insertion, the connection that results from the melting and subsequent curing of the plastic in the area of the anchoring profile is resilient and secure. The upper part of the anchoring profile to be inserted in the wooden element has at least one transverse bore. This transverse bore can be provided with a thread in order to further increase the strength of the connection in an advantageous manner.

Bei einer weiteren bevorzugten Ausführung des Pfostens wird die Verbindung zwischen Kunststoff-und Holzelementen mittels mindestens zweier Profile, die an gegenüberliegenden Teilen der Pfosten-und der Holzbalkenelemente im Verbindungsbereich angeordnet sind und die jeweils mindestens eine Querbohrung aufweisen, durch die ein seitlich in das Holzbalken- bzw. in das Pfostenelement eingetriebener Bolzen hindurchragt, hergestellt. Hierdurch ergibt sich ein insbesondere im Hinblick auf Querkräfte hoch belastbarer Verbindungsbereich.In a further preferred embodiment of the post, the connection between plastic and wooden elements is made by means of at least two profiles which are arranged on opposite parts of the post and the wooden beam elements in the connection area and which each have at least one transverse bore through which a laterally into the wooden beam or protrudes into the post element driven bolt manufactured. This results in a connection area which is particularly resilient with regard to transverse forces.

Bei einem bevorzugten Verfahren zur Herstellung eines erfindungsgemäßen Pfostenelements wird der Recycling-Kunststoff um das Verankerungselement herum in eine Form gegossen oder gepreßt, wobei das Verankerungselement im wesentlichen konzentrisch in der Form gehalten ist und die Form um eine vorgegebene Länge überragt. Diese Länge entspricht dabei demjenigen Längenanteil, um den das Verankerungselement in den hölzernen Pfostenteil hineinragen soll.In a preferred method for producing a post element according to the invention, the recycled plastic is poured or pressed around the anchoring element into a mold, the anchoring element being held essentially concentrically in the mold and projecting beyond the mold by a predetermined length. This length corresponds to the length by which the anchoring element should protrude into the wooden post part.

Dieses Verfahren hat den besonderen Vorteil, daß der Recycling-Kunststoff auch zum Verankerungselement hin vollständig und gleichmäßig und fest aushärtet, da dieses wärmeleitend ist und damit im Anschluß an das Verankerungselement ähnliche Aushärtungsbedingungen herrschen, wie zur Außenoberfläche hin. Eine besonders gute Festigkeit im Übergangsbereich zwischen Verankerungselement und Kunststoffteil läßt sich erreichen, wenn die Oberfläche des insbesondere aus Stahl bestehenden Verankerunngselements strukturiert ist, daß heißt Ausnehmungen und Erhebungen aufweist, in die der Kunststoff beim Umspritzen oder Umpressen eingreifen kann.This method has the particular advantage that the recycled plastic also cures completely and uniformly and firmly towards the anchoring element, since this is thermally conductive and therefore, following the anchoring element, there are similar curing conditions to the external surface. A particularly good strength in the transition area between the anchoring element and the plastic part can be achieved if the surface of the anchoring element, which is made in particular of steel, is structured, that is to say has recesses and elevations into which the plastic can engage during the encapsulation or encapsulation.

Entsprechend einer vorteilhaften Weiterbildung der Erfindung sind zwei Profile mittels einer Grundplatte, die zwischen den Stirnflächen der Holz- und Kunststoffelemente verläuft, miteinander verbunden. Die Profile können den Pfosten nur teilweise oder auch ganz umschließen, wodurch, je nach Profilform, Pfostenschuhe oder Doppelsteckschuhe gebildet werden.According to an advantageous development of the invention, two profiles are connected to one another by means of a base plate which runs between the end faces of the wood and plastic elements. The profiles can only partially or completely enclose the post, which means, depending on the profile shape, post shoes or double plug-in shoes are formed.

Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung ist ein abstehendes, insbesondere dorn- oder flachprofilartiges Verankerungselement an der dem Holzelement zugewandten Fläche der Grundplatte des Profils angebracht. Die Belastbarkeit einer solchen Verbindung wird insbesondere in bezug auf Querkräfte zusätzlich verbessert.According to a further advantageous development of the invention, a protruding, in particular mandrel or flat profile-like anchoring element is attached to the surface of the base plate of the profile facing the wooden element. The resilience of such a connection is additionally improved, in particular with regard to transverse forces.

Das Holzelement wird auf das Profil mit dem abstehenden Verankerungselement aufgesetzt. Dabei wirkt das Verankerungselement entweder unmittelbar als Spieß, welcher die Stirnfläche das Holzelementes beim Einrammen durchbohrt oder das Holzelement ist bereits mit einer Bohrung versehen, in die das Verankerungselement eingreift. Insbesondere bei letzterem Fall ist eine zusätzliche Verriegelung des Verankerungselementes vorteilhaft. Vorzugsweise ist dazu das Verankerungselement mit mindestens einer Querbohrung versehen, durch die der seitlich durch das Profil in das Holzelement einzutreibender Verriegelungsbolzen hindurchragt. Dadurch daß der Bolzen das Profil und das Verankerungselement verriegelt, und beide in gleicher Höhe relativ zur Grundplatte angebracht werden ist das Auffinden der Querbohrung im Verankerungselement einfach.The wooden element is placed on the profile with the protruding anchoring element. The anchoring element either acts directly as a spit, which pierces the end face of the wooden element when ramming in, or the wooden element is already provided with a hole into which the anchoring element engages. In the latter case in particular, an additional locking of the anchoring element is advantageous. For this purpose, the anchoring element is preferably provided with at least one transverse bore through which the locking bolt to be driven laterally through the profile into the wooden element projects. Because the bolt locks the profile and the anchoring element, and both are attached at the same height relative to the base plate, it is easy to find the transverse bore in the anchoring element.

Die Profile und das Verankerungselement bestehen bevorzugt wegen der erforderlichen Härte aus einem Metall-, insbesondere Eisenwerkstoff. Bei metallischem Grundmaterial besteht vorteilhafterweise die Möglichkeit, die Verbindung zwischen dem Verankerungselement und dem Profil als durch Aufschrumpfen vorzunehmen.The profiles and the anchoring element preferably consist of a metal, in particular an iron material, because of the required hardness. In the case of metallic base material, there is advantageously the possibility of making the connection between the anchoring element and the profile as by shrinking on.

Entsprechend einer vorteilhaften Weiterbildung der Erfindung sind zwei Profile mittels einer Grundplatte, die zwischen den Stirnflächen der Holz- und Kunststoffelemente verläuft, miteinander verbunden. Die Profile können den Pfosten nur teilweise oder auch ganz umschließen, wodurch, je nach Profilform, Pfostenschuhe oder Doppelsteckschuhe gebildet werden.According to an advantageous development of the invention, two profiles are connected to one another by means of a base plate which runs between the end faces of the wood and plastic elements.

Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung ist ein abstehendes, insbesondere dorn- oder flachprofilartiges Verankerungselement an der dem Holzelement zugewandten Fläche der Grundplatte des Profils angebracht.

Vorzugsweise ist dazu das Verankerungselement mit mindestens einer Querbohrung versehen, durch die der seitlich durch das Profil in das Holzelement einzutreibender Verriegelungsbolzen hindurchragt.

For this purpose, the anchoring element is preferably provided with at least one transverse bore through which the locking bolt to be driven laterally through the profile into the wooden element projects.

Der in Figur 1 dargestellter Pfosten besteht im wesentlichen aus einem mindestens teilweise im Erdreich zu verankernden Element 1 aus Recycling-Kunststoff, einem Holzelement 5 und eine Rundmetallstange als Verankerungsprofil 12. Das Verankerungsprofil 12 wird bei der Einbringung in das aus Recycling-Kunststoff bestehende Element 1 erwärmt und entweder in eine Aussparung 3 im Kunststoffelement 1 eingeführt oder in das Kunststoffelement 1 eingepreßt.The post shown in FIG. 1 essentially consists of an element 1 made of recycled plastic to be anchored at least partially in the ground, a wooden element 5 and a round metal rod as an anchoring profile 12. The anchoring profile 12 is inserted into the element 1 made of recycled plastic heated and either inserted into a recess 3 in the plastic element 1 or pressed into the plastic element 1.

Die Aussparung 3 weist bevorzugt einen kleineren Querschnitt als das Verankerungsprofil 12 auf, um eine noch bessere Verbindung, die durch das Schmelzen und die nachfolgende Verhärtung des Kunststoffs im Bereich des Verankerungsprofils 12 ensteht, zu ermöglichen. Die Stirnfläche 6 des Holzelements 5 ist mit einer, dem oberen Teil des Verankerungsprofils 12 aufnehmende Aussparung 7 ausgebildet. Dieser obere, im Holzelement 5 einzubringende Teil des Verankerungsprofils 12 ist mit zwei Querbohrungen 15 versehen, durch die eine Verschraubung 10 geführt wird um das Holzelement 5 fest mit dem Verankerungsprofil 12 zu verbinden. Diese Verbindung wird ausführlich anhand der Figur 2 erläutert. Zwischen dem Holz- 5 und dem Kunststoffelement 1 ist eine gelochte Kunststoffplatte 16 angeordnet. Aus diesem Bereich kann das vorhandene Wasser im oder an der Oberfläche des Holzelements 5 frei ablaufen. Eine Verrottung des Pfostens wird dadurch verhindert.The cutout 3 preferably has a smaller cross section than the anchoring profile 12 in order to enable an even better connection, which arises as a result of the melting and the subsequent hardening of the plastic in the region of the anchoring profile 12. The end face 6 of the wooden element 5 is formed with a recess 7 receiving the upper part of the anchoring profile 12. This upper part of the anchoring profile 12 to be inserted in the wooden element 5 is provided with two transverse bores 15 through which a screw connection 10 is guided in order to firmly connect the wooden element 5 to the anchoring profile 12. This connection is explained in detail with reference to FIG. 2. A perforated plastic plate 16 is arranged between the wooden 5 and the plastic element 1. From this area, the water present in or on the surface of the wooden element 5 can run off freely. This prevents the post from rotting.

Aus der Figur 2 ist es ersichtlich, daß das Holzelement 5 entsprechend den Querbohrungen 15 im Verankerungsprofil 12 mit Bohrungen 9, die vor oder auch nach der Einbringung des Verankerungsprofils 12 in das Holzelement 5 hergestellt werden können, versehen ist. Die Bohrungen 9 sind an beiden Enden konisch aufgeweitet und sind zur Einbringung von Senkkopfschrauben als Verschraubung 10 geeignet. Die aufgeweitete Bohrung 9 an der Oberfläche des Holzelements 5 wird mit einer Verschlußkappe 11 versehen.It can be seen from FIG. 2 that the wooden element 5 is provided with holes 9 corresponding to the transverse bores 15 in the anchoring profile 12, which bores can be produced before or even after the anchoring profile 12 has been introduced into the wooden element 5. The holes 9 are flared at both ends and are suitable for the insertion of countersunk screws as a screw 10. The widened bore 9 on the surface of the wooden element 5 is provided with a cap 11.

In den Figuren 3 und 4 werden zwei weitere Ausführungsformen eines Verankerungsprofils 12 dargestellt. In Figur 3 ist das Verankerungsprofil 12 als Flacheisen ausgebildet, welches zentrisch im Pfosten angeordnet ist und mittels zwei Paaren von Verschraubungen 10 fest mit den Kunststoff- 1 und Holzelementen 5 verbunden wird. Die Breite des Flacheisens ist kleiner als die Breite der Pfostenelemente 1, 5, so daß es auch nicht an deren Oberflächen 4, 8 in Erscheinung tritt. In Figur 4 ist das Verankerungsprofil 12 auch als Flacheisen ausgebildet, dessen Breite entspricht aber dem der Pfostenelemente 1, 5, so daß das Flacheisen bei dieser Ausführungsform bündig mit den Oberflächen 4, 8 der Pfosten 1, 5 anliegt.FIGS. 3 and 4 show two further embodiments of an anchoring profile 12. In Figure 3, the anchoring profile 12 is designed as a flat iron, which is arranged centrally in the post and is firmly connected to the plastic 1 and wooden elements 5 by means of two pairs of screw connections 10. The width of the flat iron is smaller than the width of the post elements 1, 5, so that it does not appear on their surfaces 4, 8 either. In Figure 4, the anchoring profile 12 is also designed as a flat iron, but its width corresponds to that of the post elements 1, 5, so that the flat iron in this embodiment lies flush with the surfaces 4, 8 of the posts 1, 5.

Figur 5 zeigt eine Ausführungsform der Verbindung als H-förmiges Profil 20. Das Profil 20 weist eine Grundplatte 25 und zwei an den Oberflächen des Kunststoff- und des Holzelements anliegende Schenkel 21 auf. Die untere innere Form des Profils 20 ist den Konturen des verbindungsseitigen Endabschnittes des Kunststoffelementes 1 angepaßt, so daß das Profil 20 fest auf dem Kunststoffelement 1 sitzt. Dem entsprechend sitzt das obere innere Teil des Profils auf dem verbindungsseitigen Endabschnitt des Holzelementes 5. Zur Verbesserung der Stabilität und Belastbarkeit der Verbindung zwischen dem Holzelement 5 und dem Oberteil des Profils 20 ist ein sich von der oberen Fläche der Grundplatte 25 des Profils 20 aus axial erstreckendes als Flacheisenprofil ausgebildetes Verankerungselement 28 vorgesehen, welches zwei Bohrungen 33 aufweist, durch die zwei quer in das Holzelement 5 eingeschraubte Schrauben 27 hindurchragen. Die Schrauben 27 werden auch durch die Bohrungen 26 in den zwei sich gegenüberliegenden Profilschenkeln 21 geführt.Figure 5 shows an embodiment of the connection as an H-shaped profile 20. The profile 20 has a base plate 25 and two legs 21 abutting the surfaces of the plastic and the wooden element. The lower inner shape of the profile 20 is adapted to the contours of the connection-side end section of the plastic element 1, so that the profile 20 sits firmly on the plastic element 1. Accordingly, the upper inner part of the profile sits on the connection-side end section of the wooden element 5. To improve the stability and resilience of the connection between the wooden element 5 and the upper part of the profile 20, an axially extending from the upper surface of the base plate 25 of the profile 20 extending anchoring element 28 designed as a flat iron profile is provided, which has two bores 33 through which two screws 27 protrude transversely into the wooden element 5. The screws 27 are also passed through the bores 26 in the two opposite profile legs 21.

Die Figuren 6a und 6b zeigen Querschnitte durch das Holzelement 5 entlang der Linie A-A gemäß Figur 5. In Figur 6a wird ein Holzelement 5 mit rechteckigem Querschnitt und in Figur 6b mit rundem Querschnitt dargestellt. Das Profil 20 ist als Pfostenschuh ausgebildet und umschließt die Oberfläche des Holzelements 5 nur teilweise. Bei der im Querschnitt rechteckigen Ausführung liegen die Schenkel 21 des Profils 20 nur an zwei Seiten des Holzelements 5 an und bei der runden Ausführung liegen die Schenkel 21 des Profils 20, deren Länge in etwa jeweils ein Viertel des Gesamtumfangs beträgt, in Teilbereichen an.Figures 6a and 6b show cross sections through the wooden element 5 along the line AA according to FIG. 5. A wooden element 5 with a rectangular cross-section is shown in FIG. 6a and with a round cross-section in FIG. 6b. The profile 20 is designed as a post shoe and only partially surrounds the surface of the wooden element 5. In the rectangular cross-section, the legs 21 of the profile 20 rest only on two sides of the wooden element 5 and in the round version, the legs 21 of the profile 20, the length of which is approximately a quarter of the total circumference, lie in partial areas.

Das Profil ist in den Figuren 7a und 7b als H-förmiger Doppelsteckschuh 22 ausgebildet. Die Schenkel des Profils bilden einen Kragen 21 der bei einer rechteckigen Ausführung eines Holzelements 5 eine Torsion oder Verdrehung des Holzelementes 5 innerhalb des Doppelsteckschuhs 22 bereits ausschliessen. Das Verankerungselement 28 kann demzufolge zentrisch zur Grundplatte 25 angeordnet sein. Bei einer runden Ausführung des Holzelements 5 ist der Durchmesser des Kunststoffelementes 1 im Bereich des vom Kragen 21 umschlossenen Endes geringer als der des Holzelementes 5.The profile is formed in FIGS. 7a and 7b as an H-shaped double shoe 22. The legs of the profile form a collar 21 which, in the case of a rectangular design of a wooden element 5, already precludes torsion or twisting of the wooden element 5 within the double plug-in shoe 22. The anchoring element 28 can therefore be arranged centrally to the base plate 25. In the case of a round design of the wooden element 5, the diameter of the plastic element 1 in the region of the end enclosed by the collar 21 is smaller than that of the wooden element 5.

Die ringförmige Stirnfläche des kunststoffelementseitigen Kragenteiles kann auch als Auflage für einen Absatz des Kunststoffelementes 1 dienen. Vorzugsweise ist der Durchmesser des Kunststoffelementes 1 unterhalb des Absatzes gleich dem Außendurchmesser des Doppelsteckschuhs 22, so daß ein glatter, stufenloser Übergang vom Kunststoffelement 1 zum Doppelsteckschuh 22 entsteht. Das Kunststoffelement 1 ist dann bevorzugt in den Doppelsteckschuh 22 eingeschraubt, wobei der Absatz einen Schraubanschlag bildet. Bei beiden Ausführungsformen tragen die zusätzlich eingeführte Schrauben 27, welche auch kreuzweise versetzt angeordnet werden können und durch den Kragen 21 und das Verankerungselement 28 geführt werden, zu einer höheren Stabilität der Verbindung bei.The annular end face of the collar part on the plastic element side can also serve as a support for a shoulder of the plastic element 1. Preferably, the diameter of the plastic element 1 below the shoulder is equal to the outer diameter of the double plug-in shoe 22, so that a smooth, stepless transition from the plastic element 1 to the double plug-in shoe 22 is produced. The plastic element 1 is then preferably screwed into the double plug-in shoe 22, the shoulder forming a screw stop. In both embodiments, the additionally inserted screws 27, which can also be arranged in a crosswise offset and are guided through the collar 21 and the anchoring element 28, contribute to a higher stability of the connection.

In der Figur 8 werden Flacheisenprofile eingesetzt. Zwei getrennte Flacheisen 17, 18, die an zwei Seiten 8 eines rechteckigen Holzelements 5 oder an Teilbereiche 8 eines runden Holzelements 5 anliegen, werden mittels Schrauben 27 miteinander, wie zusätzlich aus den Figuren 9a und 9b ersichtlich, verbunden.Flat iron profiles are used in FIG. Two separate flat bars 17, 18, which rest on two sides 8 of a rectangular wooden element 5 or on partial areas 8 of a round wooden element 5, are connected to one another by means of screws 27, as can additionally be seen from FIGS. 9a and 9b.

In den Figuren 10a und 10b ist das Flacheisen zum Rundprofil 19 ausgebildet und umschließt somit das Holzelement 5 und das Kunststoffelement 1.In FIGS. 10a and 10b, the flat iron is designed to form the round profile 19 and thus encloses the wooden element 5 and the plastic element 1.

In Figur 11 ist ein Winkeleisen 23 als Profil vorgesehen. Dieses weist ein auf der Grundplatte 25 angeordnetes Verankerungselement 28 auf, das in das Holzelement 5 und in das Kunststoffelement 1 hineinragt und jeweils auf beiden Seiten der Grundplatte 25 mit zwei Schrauben 27, die durch die Bohrungen 33 in das Verankerungselement 28 geführt werden, befestigt werden. Das Winkeleisen 23 kann entweder gemäß der Figuren 12a und 12b nur an einen Teil der Oberflächen 4, 8 anliegen oder gemäß den Figuren 13a und 13b als Halbringprofile 24 ausgebildet werden. Die Halbringprofile 24 sind wesentlich stabiler als das einfache Winkeleisen 23 und die Holzelemente 5 können seitlich ausgespart werden um eine bündige Oberfläche im Bereich der Verbindung zu erzielen.In Figure 11, an angle iron 23 is provided as a profile. This has an anchoring element 28 arranged on the base plate 25, which protrudes into the wooden element 5 and into the plastic element 1 and is fastened on both sides of the base plate 25 with two screws 27, which are guided through the bores 33 into the anchoring element 28 . The angle iron 23 can either be in contact with only a part of the surfaces 4, 8 according to FIGS. 12a and 12b or may be designed as a half-ring profile 24 according to FIGS. 13a and 13b. The half-ring profiles 24 are much more stable than the simple angle iron 23 and the wooden elements 5 can be left out laterally in order to achieve a flush surface in the area of the connection.

Bei dem - in der Zeichnung nicht dargestellten - Verfahren zur Herstellung eines erfindungsgemäßen Pfostenelements wird der Recycling-Kunststoff um das Verankerungselement herum in eine Form gegossen oder gepreßt, wobei das Verankerungselement im wesentlichen konzentrisch in der Form gehalten ist und die Form um eine vorgegebene Länge überragt. Diese Länge entspricht dabei demjenigen Längenanteil, um den das Verankerungselement in den hölzernen Pfostenteil hineinragen soll. Der Recycling-Kunststoff härtet hierbei auch zum Verankerungselement hin vollständig, gleichmäßig und fest aus, da dieses aus einem metallischen Werkstoff besteht, somit wärmeleitend ist und damit im Anschluß an das Verankerungselement ähnliche Aushärtungsbedingungen herrschen, wie zur Außenoberfläche hin. Eine besonders gute Festigkeit im Übergangsbereich zwischen Verankerungselement und Kunststoffteil läßt sich erreichen, wenn die Oberfläche des, insbesondere aus Stahl bestehenden, Verankerunngselements strukturiert ist, daß heißt Ausnehmungen und Erhebungen aufweist, in die der Kunststoff beim Umspritzen oder Umpressen eingreifen kann.In the - for the production of a post element according to the invention - not shown in the drawing - the recycled plastic is poured or pressed around the anchoring element into a mold, the anchoring element being held essentially concentrically in the mold and projecting beyond the mold by a predetermined length . This length corresponds to the length by which the anchoring element should protrude into the wooden post part. The recycled plastic also hardens completely, evenly and firmly towards the anchoring element, since this consists of a metallic material, and is therefore heat-conducting, and consequently, after the anchoring element, there are similar curing conditions to the outer surface. A particularly good strength in the transition area between the anchoring element and the plastic part can be achieved if the surface of the anchoring element, in particular made of steel, is structured, that is to say it has recesses and elevations into which the plastic can engage during the encapsulation or encapsulation.

Die Erfindung beschränkt sich in ihrer Ausführung nicht auf das vorstehend angegebene bevorzugte Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch macht.The embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different types.
