Description

Die Erfindung betrifft eine Stufe in oder an der Gehfläche eines Gehweges auf nicht verbautem Untergrund, umfassend ein Stützmodul für den vertikalen Bereich der Stufe, sowie eine seitliche Abstützung eines einen Hang querenden Gehweges.The invention relates to a step in or on the walking surface of a walkway on non-built ground, comprising a support module for the vertical area of the step, as well as a lateral support of a walkway crossing a slope.

Gemäß einer sehr üblichen Bauweise für Stufen an geneigten Abschnitten von Wander- oder Spazierwegen wird ein Holzbrett mit vertikal ausgerichteter Fläche und quer zur Wegrichtung ausgerichteter Längsrichtung als Stützteil für eine Stufe am Weg angeordnet. Talseitig lehnt das Brett an Stahlspießen, die vor dem Brett in den Untergrund geschlagen sind. An der Bergseite des Brettes ist Untergrundmaterial - Erde, Schotter, Steine - angeschüttet um eine etwa horizontale Trittfläche zu bilden. Oftmals wird anstatt eines Brettes auch ein Rundholz verwendet. Die Bauweise mit einem am geneigten Untergrund aufliegenden liegenden Holzbrett oder Rundholz, welches talseitig durch Spieße gestützt ist, welche in den Untergrund geschlagen sind und mit ihrem hervorstehenden Längsbereich an der Talseite des Holzes seitlich anliegen, wird bekanntermaßen nicht nur für Stufen von Gehwegen verwendet, sondern auch als talseitige seitliche Stütze von Gehwegen welche in geneigtem Gelände einen Hang queren. Die einfache und kostengünstige Bauweise dieses aus Holz und Stahlspießen gebildeten Stützmoduls hat an Nachteilen geringe Haltbarkeit, Rutschgefahr an nassem Holz und Verletzungsgefahr an den Metallspießen. Oftmals ragen die Metallspieße nämlich noch jahrelang, nachdem das Holz schon weggemorscht ist, aus dem Untergrund.According to a very common construction method for steps on inclined sections of hiking or walking paths, a wooden board with a vertically aligned surface and a longitudinal direction aligned perpendicular to the direction of the path is arranged as a support for a step on the path. On the valley side, the board leans on steel spikes that are driven into the ground in front of the board. On the uphill side of the board, subsoil material - earth, gravel, stones - is piled up to form an approximately horizontal step surface. Often, a round piece of wood is used instead of a board. The construction method with a wooden board or round piece of wood resting on the inclined ground, which is supported on the valley side by spikes that are driven into the ground and with their protruding longitudinal area rests laterally on the valley side of the wood, is known to be used not only for steps on walkways, but also as a valley-side lateral support for walkways that cross a slope on sloping terrain. The simple and inexpensive design of this support module made of wood and steel skewers has the disadvantages of low durability, the risk of slipping on wet wood and the risk of injury from the metal skewers. The metal skewers often protrude from the ground for years after the wood has rotted away.

Die Schriften EP 753645 B1 , DE 9316169 U1 , EP 3461966 A1 und GB 2410038 A zeigen Stufenelemente, welche weniger als dauerhafte Stufen in der Landschaft verankert werden, sondern eher als temporäre Arbeitsplattform verwendet werden. Sie weisen jeweils eine horizontale Standfläche auf, von deren Rändern steckbare Bereiche (Wände oder Stäbe) vertikal nach unten ragen, die bestimmungsgemäß etwas in den Untergrund gesteckt sind. Vermutlich auf Grund von Sperrigkeit und hohem Gewicht hat sich die Bauweise nicht für dauerhafte Anordnung an Manderwegen etabliert.The writings EP753645B1 , DE 9316169 U1 , EP3461966A1 and GB2410038A show step elements that are not anchored in the landscape as permanent steps, but are used more as temporary work platforms. They each have a horizontal base, from the edges of which pluggable areas (walls or rods) protrude vertically downwards, which are inserted somewhat into the ground as intended. Presumably due to Due to its bulkiness and high weight, the construction method has not been established for permanent arrangement on mander paths.

Gemäß der US 3343316 A werden Stufen gebildet, indem Betonprofile mit L-Querschnitt so auf Hänge gelegt werden, dass die größere Profilfläche horizontal liegt und die kleinere Profilfläche an der Talseite der größeren Profilfläche von dieser vertikal nach unten ragt. Zur Verankerung werden Spieße durch Durchbrüche am freien Endbereich der größeren Profilfläche hindurch in den Untergrund geschlagen. Die Durchbrüche und damit die oberen. Enden der Spieße werden durch das nächst oben aufliegende Betonprofil abgedeckt. Die Bauweise ist auf Grund des Gewichtes der Stufenelemente nur gut an Stellen anwendbar, an denen mit Baumaschinen zugefahren werden kann. Die DE 4131349 A1 zeigt eine zur US 3343316 A stark verwandte Bauweise mit den gleichen Nachteilen.According to the US 3343316 A Steps are formed by placing concrete profiles with an L-section on slopes in such a way that the larger profile surface is horizontal and the smaller profile surface on the valley side of the larger profile surface protrudes vertically downwards. For anchoring, spikes are driven into the subsoil through openings at the free end of the larger profile surface. The openings and thus the upper ends of the spikes are covered by the concrete profile next on top. Due to the weight of the step elements, the construction method is only suitable for use in places where construction machinery can be driven in. The DE 4131349 A1 shows a US 3343316 A closely related construction with the same disadvantages.

Auch die FR 1462370 A zeigt ein Stufenelement für temporäre Anwendung. Zwei Dreieck-Rahmenelemente bilden,' die Seitenelemente eines Stufenelementes. Die Seitenelemente sind durch eine horizontale, geriffelte Trittfläche verbunden. Am Hang ist das so gebildete Stufenelement durch Spieße oder durch verhaken an jeweils einem oberen Stufenelement gehalten. Für dauerhafte Anwendung ist die Bauweise zu filigran und auch zu schlecht an unterschiedliche Hangneigungen anpassbar.Also the FR 1462370 A shows a step element for temporary use. Two triangular frame elements form the side elements of a step element. The side elements are connected by a horizontal, grooved tread. On the slope, the step element formed in this way is held by spikes or by hooking onto an upper step element. For permanent use, the construction is too delicate and also too difficult to adapt to different slope gradients.

Die GB 2410038 A und die EP 753645 B1 zeigen aus mehreren Stufen bestehende Treppenabschnitte, welche jeweils durch eine Blechfläche gebildet sind, die durch abwechselnde 90°-Büge zu einer ZickZack-Fläche gebogen und auf einen Hang aufgelegt ist. Sie ist durch Spieße, die durch die Blechfläche hindurch in das Hangmaterial verlaufen, am Hang verankert. Die Bauweise ist nicht an verschiedene Hangneigungen anpassbar.The GB2410038A and the EP753645B1 show staircase sections consisting of several steps, each of which is formed by a sheet metal surface that is bent into a zigzag surface by alternating 90° bends and placed on a slope. It is anchored to the slope by spikes that run through the sheet metal surface into the slope material. The construction cannot be adapted to different slope gradients.

Die EP 2657403 B1 zeigt einen Stützteil für eine Stufe eines Gehweges wobei der Stützteil ein Blechteil ist und ähnlich wie das ganz oben erwähnte Holzbrett die vertikale Fläche der Stufe bildet. Der Blechteil ist durch Spieße, die in den Untergrund geschlagen sind, am, Untergrund verankert. Mit dem Blechteil sind die Spieße entweder starr verbunden oder an diesem jeweils durch ein mit dem Blechteil verschweißtes Rohr geführt. Die Bauweise ist sehr robust und flexibel einsetzbar und begünstigt die gegenseitig stabilisierende Verbindung des Stützteils mit einem Handlaufsteher. Nachteilig sind ein hoher Herstellungsaufwand und ggf. die nach oben offenen Rohre für die Durchführung der Spieße. Die DE 103 03 640 A1 beschreibt mehrere Bauweisen von Metallstellwänden als Ersatz für Betonfertigteile oder Natursteine für die Anwendung an nicht verbautem Untergrund. Die mögliche Anwendung der Bauweise als Stütze für Stufen in oder an der Gehfläche eines Gehweges wird dabei nicht angedacht oder erwähnt. Gemäß einer Bauweise hat die Stellwand die Form, eines flachen U-Profils, welches im Einsatz mit einer unten liegendenFlankenfläche angeordnet ist, wobei eine Verankerung am Untergrund durch Spieße oder Ähnliches bewirkt wird, welche durch Durchbrücke in der unteren Flankenfläche hindurch in den Untergrund eingesteckt sind.The EP2657403B1 shows a support part for a step of a walkway where the support part is a sheet metal part and similar to the The wooden board mentioned above forms the vertical surface of the step.

The spikes are either rigidly connected to the sheet metal part or are guided to it by a pipe that is welded to the sheet metal part. The construction is very robust and flexible and promotes the mutually stabilizing connection of the support part with a handrail post. The disadvantages are the high manufacturing costs and possibly the pipes that are open at the top for the spikes to pass through. The EN 103 03 640 A1 describes several designs of metal partition walls as a replacement for precast concrete parts or natural stones for use on non-built-up subsoil. The possible use of the design as a support for steps in or on the walking surface of a walkway is not considered or mentioned. According to one design, the partition wall has the shape of a flat U-profile, which is arranged with a flank surface underneath when in use, whereby anchoring to the subsoil is achieved by spikes or similar, which are inserted into the subsoil through a bridge in the lower flank surface.

Die JP S5973436 U zeigt ein Stützelement für jene Kante einer Treppenstufe, welche zwischen der vertikale Frontfläche der Stufe und der oben daran anschließenden Trittfläche anliegt. Das Stützelement umfasst ein Winkelprofil welches entlang der besagten Kante verläuft, wobei der eine Winkelschenkel an der vertikalen Fläche der Stufe anliegt und der zweite, horizontal ausgerichtete Winkelschenkel die Trittfläche nach vorne hin verlängert. Gehalten wird das Winkelprofil durch zwei senkrecht in der Erde steckende Spieße, welche mit aus der Erde herausragenden Längsbereichen in den Winkel zwischen den beiden. Winkelschenkeln ragen und dabei an beiden Winkelschenkeln anliegen. Die Oberseite des horizontal ausgerichteten Winkelschenkels hat eine geriffelte, und damit rutschhemmende Oberfläche. Die Bauweise ist sehr einfach, jedoch ist die Stützwirkung sowohl nach vorne als auch nach unten hin gering und von den vielen vorstehenden Kanten geht Verletzungsgefahr aus.The JP S5973436 U shows a support element for the edge of a stair step which is located between the vertical front surface of the step and the tread surface above it. The support element comprises an angle profile which runs along the said edge, with one angle leg lying on the vertical surface of the step and the second, horizontally aligned angle leg extending the tread surface forwards. The angle profile is held by two spikes stuck vertically into the ground, which protrude with longitudinal areas protruding from the ground into the angle between the two angle legs and thereby lie against both angle legs. The top of the horizontally aligned angle leg has a grooved, and This creates a non-slip surface. The design is very simple, but the support is low both to the front and to the bottom and the many protruding edges pose a risk of injury.

Die EP 2319294 A1 und die GB 215529 A zeigen längliche metallische Elemente, welche zur Abgrenzung zwischen zwei im Wesentlichen gleich hohen Flächenbereichen im Freien, typischerweise im Garten dienen, beispielsweise zwischen einer Rasenfläche oder einem Beet einerseits und einem geschotterten Gehweg andererseits.The EP 2319294 A1 and the GB215529A show elongated metallic elements which serve to demarcate two essentially equally high outdoor areas, typically in the garden, for example between a lawn or a flowerbed on the one hand and a gravelled walkway on the other.

Die der Erfindung zu Grunde liegende Aufgabe besteht darin, ein Stützmodul für den vertikalen Bereich einer Stufe in oder an der Gehfläche eines Gehweges im Außenbereich bereitzustellen, wobei das Stützmodul im Wesentlichen aus Blech besteht. Gegenüber dem aus der EP 2657403 B1 bekannten Stützmodul, welches aus Stützteil und Spießen besteht, soll es einfacher herstellbar sein und gegenüber den aus der JP S5973436 U und der DE 103 03 640 A1 bekannten Stützelementen soll es eine bessere Stützwirkung haben und ein ebenmäßigeres Äußeres ermöglichen.The object underlying the invention is to provide a support module for the vertical area of a step in or on the walking surface of an outdoor walkway, wherein the support module consists essentially of sheet metal. Compared to the EP2657403B1 known support module, which consists of support part and spikes, it should be easier to manufacture and compared to the JP S5973436 U and the EN 103 03 640 A1 It is intended to have a better supporting effect than known support elements and to enable a more even appearance.

Zum. Lösen der Aufgabe wird von den bekannten Merkmalen ausgegangen, dass das Stützmodul aus einem Stützteil aus Blech und aus Spießen besteht, wobei die Spieße jeweils einen Bereich des Stützteils durchdringen und in den Untergrund hineingesteckt sind.To solve the problem, the known features are assumed that the support module consists of a support part made of sheet metal and of spikes, whereby the spikes each penetrate an area of the support part and are inserted into the ground.

Als Weiterentwicklung dazu wird vorgeschlagen, den Stützteil als Rinnenprofil aus Blech auszubilden, bei welchem eine Profilnut durch eine mittlere Basisfläche und zwei seitliche Flankenflächen begrenzt wird, wobei bei beiden Flankenflächen an die jeweilige freie Längsseite eine in Richtung auf die Profilnut hin gebogene Einfassungsfläche anschließt, und wobei eine der beiden Flankenflächen Durchbrüche für die Spieße aufweist.As a further development, it is proposed to design the support part as a gutter profile made of sheet metal, in which a profile groove is delimited by a central base surface and two lateral flank surfaces, wherein on both flank surfaces an edging surface curved in the direction of the profile groove adjoins the respective free longitudinal side, and wherein one of the two flank surfaces has openings for the skewers.

Wenn der Stützteil als Stufe im Gehweg angewendet wird - also so dass oberhalb und unterhalb des Stützteils die Gehfläche anschließt -, so ist die zweite Flankenfläche an ihrer Außenseite 2. insbesondere mit einer rutschhemmenden Oberfläche versehen.If the support part is used as a step in the walkway - i.e. so that the walking surface is above and below the support part - the second flank surface is provided on its outer side 2. in particular with an anti-slip surface.

Wenn der Stützteil hingegen als talseitliche Stützstufe an der Gehfläche eines einen Hang querenden Gehweges angewendet wird-also so dass nur oberhalb des Stützteils die Gehfläche anschließt, so braucht keine Fläche mit einer rutschhemmenden Oberfläche versehen zu sein.However, if the support part is used as a valley-side support step on the walking surface of a footpath crossing a slope - i.e. so that the walking surface only connects above the support part, then no surface needs to be provided with an anti-slip surface.

An Hand von Zeichnungen wird die Erfindung einschließlich vorteilhafter Weiterentwicklungen veranschaulicht und näher erklärt.The invention, including advantageous further developments, is illustrated and explained in more detail with the aid of drawings.

Die Zeichnungen sind vor allem dahingehend etwas stilisiert, dass sie nicht vollkommen maßstabsgetreu sind und dass manche Blechbiegungen nicht rund dargestellt sind sondern eckig.

Die in Fig. 1 gut erkennbare Grundausführung eines Stützteils 1 eines erfindungsgemäßen Stützmoduls ist ein Rinnenprofil - also ein Art C-Profil. In eigebautem Zustand ist es mit zumindest annähernd vertikal stehender Basisfläche 2 angeordnet.In the Fig.1 The clearly visible basic design of a support part 1 of a support module according to the invention is a channel profile - a type of C-profile. When installed, it is arranged with the base surface 2 at least approximately vertical.

Die in Einbausituation unten liegende erste Flankenfläche 3 ist durch Durchbrüche 4 durchbrochen. Es sollte zumindest an jedem Längsende ein derartiger Durchbruch 4 vorhanden sein. Es kann sich aber auch ein Raster von zueinander beabstandeten Durchbrüchen über die gesamte Länge der ersten Flankenfläche erstrecken. Die in Einbausituation oben liegende zweite Flankenfläche 5 ist an ihrer Außenseite mit einer rutschhemmenden Oberfläche versehen. In den hier dargestellten Beispielen ist diese durch einen Raster von Erhebungen 6 gebildet, deren höchste Bereiche die Ränder von nach außen (oben) hin gestanzten Durchbrüchen sind. Es wäre natürlich auch möglich als rutschhemmende Oberfläche an der Außenseite der zweiten Flankenfläche 5 einen separaten rutschhemmenden Belag anzubringen, beispielsweise eine Gummischicht oder ein feines Drahtgitter oder einen Sandkörner enthaltenden Lack.The first flank surface 3, which is located at the bottom in the installation situation, is perforated by openings 4. There should be at least one such opening 4 at each longitudinal end. However, a grid of spaced-apart openings can also extend over the entire length of the first flank surface. The second flank surface 5, which is located at the top in the installation situation, is provided with an anti-slip surface on its outside. In the examples shown here, this is formed by a grid of elevations 6, the highest areas of which are the edges of openings punched outwards (at the top). It would of course also be possible to apply a separate anti-slip coating as an anti-slip surface to the outside of the second flank surface 5, for example a layer of rubber or a fine wire mesh or a varnish containing grains of sand.

An jener Längskante der Flankenflächen 3, 5, welche der Basisfläche 2 gegenüberliegt, folgt auf die Flankenfläche 3,5 jeweils eine Fläche, welche des weiteren als Einfassungsfläche 7 bezeichnet wird, und von der jeweiligen Flankenfläche 3, 5 in Richtung auf die durch Basisfläche 2 und Flankenflächen 3, 5 eingeschlossene Profilnut gebogen ist. in Einbaulage ragt also die obere Einfassungsfläche 7 nach unten hin von der der Flankenfläche 5 weg, und die untere Einfassungsfläche 7 ragt nach oben hin von der Flankenfläche 3 weg. Die Einfassungsflächen 7 erhöhen, auf sehr ökonomische Art die Festigkeit des Stützteils 1 gegen diverse Biegeverformungen.At the longitudinal edge of the flank surfaces 3, 5 which is opposite the base surface 2, the flank surface 3, 5 is followed by a surface which is further referred to as the edging surface 7. and is bent from the respective flank surface 3, 5 in the direction of the profile groove enclosed by the base surface 2 and flank surfaces 3, 5. In the installed position, the upper edging surface 7 projects downwards away from the flank surface 5, and the lower edging surface 7 projects upwards away from the flank surface 3. The edging surfaces 7 increase the strength of the support part 1 against various bending deformations in a very economical manner.

Sowohl dieser einfache Stützteil 1 als auch der an Hand von Fig. 3 weiter unten näher besprochene weiterentwickelte Stützteil 8 sind einfach aus einem Blechband durch Stanzen und Rollverformung zu bilden.Both this simple support part 1 and the one based on Fig.3 The further developed support part 8, discussed in more detail below, can be easily formed from a sheet metal strip by punching and rolling.

Anhand von Fig. 2 werden die Funktionen der erwähnten Einzelheiten gut verständlich:
Die Basisfläche 2 bildet die vertikale Fläche einer Stufe in bzw. an der Gehfläche eines Gehweges im Freien. Die äußere Seite der Basisfläche 2 ist dabei die Sichtseite der Stufe. Die untere, erste Flankenfläche 3 liegt auf dem Untergrund auf. Durch mindestens zwei ihrer Durchbrüche 4 verläuft jeweils ein Spieß 9 hindurch. Die Spieße 9 wurden vor dem Anbringen, des Stützteils 1 in den Untergrund geschlagen, und dann wurde der Stützteil 1 von oben her auf die frei hervorragenden Enden aufgesteckt. Als Spieß dient typischerweise ein verzinkter Rundstahl, beispielsweise mit 15 mm Durchmesser. Die Spieße sind gerade soweit in den Untergrund eingeschlagen - bzw. so oben abgeschnitten - dass ihr oberster Längsbereich in den Höhenbereich der oberen Einfassungsfläche 7 ragt, sodass diese mit ihrer Innenseite an den Spießen 9 anliegen kann.Based on Fig.2 the functions of the mentioned details become well understandable:
The base surface 2 forms the vertical surface of a step in or on the walking surface of an outdoor walkway. The outer side of the base surface 2 is the visible side of the step. The lower, first flank surface 3 rests on the ground. A spike 9 runs through at least two of its openings 4. The spikes 9 were hammered into the ground before the support part 1 was attached, and then the support part 1 was placed from above onto the freely protruding ends. A galvanized round steel bar, for example with a diameter of 15 mm, is typically used as a spike. The spikes are hammered into the ground just far enough - or cut off at the top - that their uppermost longitudinal area projects into the height area of the upper edging surface 7, so that the inside of the upper edging surface can rest against the spikes 9.

An die Rückseite des Stützteils 1 - also in die durch Basisfläche 2 und Flankenflächen 3, 5 gebildete Rinne - wird Untergrundmaterial 10 (Steine, Schotter, Erdreich) angeschüttet, sodass eine Trittfläche gebildet wird, welche im wesentlichen bündig mit der zweiten Flankenfläche 5 liegt.Subsoil material 10 (stones, gravel, soil) is piled up onto the back of the support part 1 - i.e. into the channel formed by the base surface 2 and the flank surfaces 3, 5 - so that a tread surface is formed which is substantially flush with the second flank surface 5.

Der Stützteil 8 von Fig. 3 ist gegenüber dem Stützteil 2 von Fig. 1 und Fig. 2 etwas weiterentwickelt.The support part 8 of Fig.3 is opposite the support part 2 of Fig.1 and Fig.2 somewhat further developed.

Die Basisfläche 11 ist gestreckt S-förmig gebogen, sodass sie in Einbausituation an ihrer Außenseite einen überhängenden Bereich 12 aufweist. Damit ist eine sogenannte Stufennase gebildet. Gegenüber einer ebenen Basisfläche wird damit eine geringfügig längere Trittfläche an der Stufe erreicht und das optische Erscheinungsbild wird stark verbessert.The base surface 11 is bent in an elongated S-shape so that it has an overhanging area 12 on its outside when installed. This forms a so-called step nose. Compared to a flat base surface, this results in a slightly longer tread on the step and the visual appearance is greatly improved.

Gemäß Fig. 4 und Fig. 6 ist an dem Stützteil 8 ein Seitenblech 14 angebracht. Das in Fig. 5 perspektivisch für sich allein skizzierte Seitenblech 14 ist dann nützlich, wenn der Stützteil 1 nicht in eine Vertiefung in einer Hangfläche eingesetzt ist, sondern erhaben über der Hangfläche angeordnet ist. Das Seitenblech 14 verhindert dann, dass Untergrundmaterial, welches auf der Hinterseite des Stützteils 8 zwecks Bildung einer Trittfläche aufgeschüttet ist, seitliche wegrieselt oder weggespült wird.According to Fig.4 and Fig.6 A side plate 14 is attached to the support part 8. The Fig.5 The side plate 14, which is sketched in perspective on its own, is useful when the support part 1 is not inserted into a recess in a slope, but is arranged raised above the slope. The side plate 14 then prevents subsoil material, which is piled up on the rear side of the support part 8 for the purpose of forming a tread surface, from trickling away or being washed away.

Die Hauptfläche 15 des Seitenblechs 14 erstreckt sich normal zur Basisfläche 11 des Stützteils 8 über die Hinterseite des Stützteils 8 hinaus nach hinten, also vom Stützteil 8 aus zur Bergseite des Hanges hin. Gemäß einer bevorzugten Bauweise ragen Blechzungen 16, 17 von der Hauptfläche 15 des Seitenblechs 14 in den durch die Flankenflächen 5, 13 und die Basisfläche 11 eingegrenzte Profilnut am Stützteil 8 hinein und liegen dort unter elastischer Vorspannung an den Flankenflächen 5, 13 an. Die untere Blechzunge 17 ist zusätzlich mit einem gekrümmten Endbereich an einem Durchbruch 4 in der ersten (unteren) Flankenfläche 13 verhakt. Diese Verbindung zwischen Stützteil 8 und Seitenblech 14 ist im Bedarfsfall einfach am Einsatzort auch ohne Hilfswerkzeug herstellbar.The main surface 15 of the side plate 14 extends perpendicular to the base surface 11 of the support part 8 beyond the rear side of the support part 8 to the rear, i.e. from the support part 8 to the mountain side of the slope. According to a preferred design, sheet metal tongues 16, 17 protrude from the main surface 15 of the side plate 14 into the profile groove on the support part 8 delimited by the flank surfaces 5, 13 and the base surface 11 and rest there under elastic prestress on the flank surfaces 5, 13. The lower sheet metal tongue 17 is additionally hooked with a curved end region to an opening 4 in the first (lower) flank surface 13. This connection between the support part 8 and the side plate 14 can be easily produced on site if necessary, even without auxiliary tools.

Der erfindungsgemäß ausgeführte Stützteil 1, 8 lässt sich sehr gut mit einer Wasserrinne 18 als optionalem Zusatzteil kombinieren - wie in Fig. 7 und Fig. 8 gezeigt.The support part 1, 8 designed according to the invention can be combined very well with a water channel 18 as an optional additional part - as in Fig.7 and Fig.8 shown.

Die Wasserrinne 18 verläuft an dem Stützteil 8 entlang in der oberhalb des Stützteils 8 befindlichen Trittfläche. Sie dient dazu, Wasser, welches an die Trittfläche gelangt, seitlich wegzuleiten.The water channel 18 runs along the support part 8 in the tread area located above the support part 8. It serves to direct water that reaches the tread area away to the side.

Die dargestellte Wasserrinne 18 ist ein Wannenprofil mit einer Basisfläche 19 und zwei Flankenflächen 20. in dem gezeigten optionalen vorteilhaften Fall nimmt die Höhe der Wasserrinne 18 über deren Länge stetig zu, d.h. die Basisfläche 19 ist gegenüber der oberen, horizontal verlaufend angenommen Stirnseite der Flankenflächen. 20 um mehrere Winkelgrade geneigt, wie es für Abflusskanäle günstig ist.The water channel 18 shown is a trough profile with a base surface 19 and two flank surfaces 20. In the optional advantageous case shown, the height of the water channel 18 increases continuously over its length, i.e. the base surface 19 is inclined by several degrees relative to the upper, assumed horizontally running front side of the flank surfaces 20, as is advantageous for drainage channels.

Eine der beiden Flankenflächen 20 der Wasserrinne 18 liegt mit ihrem oberen inneren Bereich flächig an der Innenseite der Einfassungsfläche 7 des Stützteils 8 an. Die obere Stirnfläche der besagten Flankenfläche 20 kann an der zweiten (oberen) Flankenfläche 5 des Stützteils anliegen. An der Außenseite der Flankenfläche 20 liegt der Spieß 9 an.One of the two flank surfaces 20 of the water channel 18 rests with its upper inner area flat on the inside of the edging surface 7 of the support part 8. The upper end face of the said flank surface 20 can rest on the second (upper) flank surface 5 of the support part. The spike 9 rests on the outside of the flank surface 20.

Mit der Unterseite ihrer Basisfläche 19 liegt die Wasserrinne 18 auf dem Untergrundmaterial 10 auf. Wie in Fig. 8 gezeigt kann die Wasserrinne 18 seitlich über den Stützteil 8 vorstehen und damit Wasser vom unmittelbaren Nahbereich des Stützteils 8 wegleiten.The underside of its base surface 19 of the water channel 18 rests on the substrate material 10. As in Fig.8 As shown, the water channel 18 can protrude laterally over the support part 8 and thus direct water away from the immediate vicinity of the support part 8.

In Fig. 9 ist ein Stützteil 21 gezeigt, an welchem, monolithisch ; eine Wasserrinne 22 angeformt ist. Dazu ist die Einfassungsfläche 23 gleichzeitig Flankenfläche der Wasserrinne 22, wobei sich die Wasserrinne 22 an der Hinterseite des Stützteils 21 erstreckt und neben der ersten Flankenfläche auch eine Basisfläche 24 und eine zweite Flankenfläche 25 aufweist. Auch diese Bauweise eines Stützteils 21 ist durch Rollverformung und Stanzen eines Blechbandes herstellbar.In Fig.9 a support part 21 is shown, onto which a water channel 22 is formed monolithically. For this purpose, the edging surface 23 is simultaneously the flank surface of the water channel 22, whereby the water channel 22 extends on the rear side of the support part 21 and, in addition to the first flank surface, also has a base surface 24 and a second flank surface 25. This type of construction of a support part 21 can also be produced by rolling and punching a sheet metal strip.

Fig. 10 und Fig. 11 befassen sich mit einem erfindungsgemäßen Stützmodul bzw. Stützteil 26 für den Anwendungsfall als talseitige seitliche Stütze eines Gehweges, welcher - mit oder ohne Stei_, gung - einen Hang quert. Fig.10 and Fig. 11 deal with a support module or support part 26 according to the invention for use as a valley-side lateral support of a walkway which crosses a slope - with or without a gradient.

Der Stützteil 26 ist wiederum ein Rinnenprofil, also ein Art C-Profil. In eigebautem Zustand ist es mit zumindest annähernd vertikal stehender Basisfläche 2 angeordnet. Die in Einbausituation unten liegende erste Flankenfläche 3 ist durch Durchbrüche 4 durchbrochen. Es sollte zumindest an jedem Längsende ein derartiger Durchbruch 4 vorhanden sein. Es kann sich aber auch ein Raster von zueinander beabstandeten Durchbrüchen 4 über die gesamte Länge der ersten Flankenfläche 3 erstrecken.The support part 26 is again a channel profile, i.e. a type of C-profile. When installed, it is arranged with the base surface 2 at least approximately vertical. The first flank surface 3, which is located at the bottom in the installed situation, is pierced by openings 4. There should be at least one such opening 4 at each longitudinal end. However, a grid of openings 4 spaced apart from one another can also extend over the entire length of the first flank surface 3.

Die in Einbausituation oben liegende zweite Flankenfläche 27 ist anders als bei den vorher besprochenen Stützteilen 1, 8, 21 aus wirtschaftlichen Gründen nicht mit einer rutschhemmenden Oberfläche versehen, da sie gar nicht als Trittfläche für Menschen die zu Fuß unterwegs sind, zu dienen braucht.Unlike the previously discussed support parts 1, 8, 21, the second flank surface 27, which is located at the top in the installation situation, is not provided with an anti-slip surface for economic reasons, since it does not actually need to serve as a tread for people on foot.

Auf jene Längskante der Flankenflächen 3, 27, welche der Basisfläche 2 gegenüberliegt, folgt jeweils wieder eine Einfassungsfläche 7, welche von der jeweiligen Flankenfläche 3, 27 in Richtung auf die durch Basisfläche 2 und Flankenflächen 3, 27 eingeschlossene Profilnut gebogen ist. Die Einfassungsflächen 7 erhöhen auf sehr ökonomische Art die Festigkeit des Stützteils 1 gegen diverse Biegeverformungen.The longitudinal edge of the flank surfaces 3, 27 which is opposite the base surface 2 is followed by a border surface 7 which is bent from the respective flank surface 3, 27 in the direction of the profile groove enclosed by the base surface 2 and flank surfaces 3, 27. The border surfaces 7 increase the strength of the support part 1 against various bending deformations in a very economical manner.

Die Anwendung der Stützteile 26 an Gehwegen bedingt, dass sie durch Menschen zum Einsatzort getragen werden müssen - oft über mehrere hundert Meter. Aus diesem Grund sollte ein Stützteil 26 nicht mehr als maximal etwa 20 kg wiegen, besser nicht mehr als 15 kg. Durch die erfindungsgemäß vorgeschlagene Bauweise als C-Profil ist es beispielsweise gut möglich einen Stützteil 26 aus Stahlblech so auszubilden, dass er bei 2,8 m Länge und 20 cm Höhe nur knapp 15 kg wiegt und dennoch ausreichend robust gegenüber allen betriebsmäßig zu erwartenden Belastungen ist. Ein RechteckHohlprofil aus Stahlblech mit gleichen Außenmaßen und vergleichbarer Robustheit wäre demgegenüber deutlich schwerer.The use of the support parts 26 on sidewalks means that they have to be carried to the place of use by people - often over several hundred meters. For this reason, a support part 26 should not weigh more than about 20 kg, preferably not more than 15 kg. The C-profile design proposed according to the invention makes it possible, for example, to design a support part 26 from sheet steel so that it weighs just under 15 kg at a length of 2.8 m and a height of 20 cm and is nevertheless sufficiently robust against all the loads that can be expected during operation. A rectangular hollow profile made of sheet steel with the same external dimensions and comparable robustness would be significantly heavier.

Da sich Hangquerungen, von Gehwegen sehr oft über längere Distanzen erstrecken, ist es notwendig mehrere Stützteile 26 entlang eines Gehweges aneinandergereiht anzuordnen. Damit benachbarte Stützteile 26 einfach miteinander verkettet werden können sind sie bevorzugt wie in Fig. 10 erkennbar stirnseitig mit einer Lasche 28 versehen die durch Schraubendurchgangsöffnungen 29 durchbrochen sind. Dabei sind beide Stirnseiten eines Stützteils 26 mit jeweils einer Lasche 28 versehen, und die Fläche einer Lasche erstreckt sich bevorzugt normal zur Längsrichtung des Stützteils 26 in die Querschnittsfläche der durch die Basisfläche 2 und die Flankenflächen 7 begrenzten Rinne. Für die Längsverbindung zweier Stützteile 26, können die einander zugewandt angeordneten Stirnseiten der beiden Stützteile einfach durch Schrauben und zugehörige Muttern verbunden werden, wobei sich die Schrauben durch die fluchtend zueinander liegenden Schraubendurchgangsöffnungen 29 in den beiden aneinander liegenden Laschen 28 der beiden Stützteile 26 erstrecken. indem der Schraubendurchmesser kleiner gewählt wird als der Durchmesser der Schraubendurchgangsöffnungen 29 und indem die Verschraubungen nicht fest angezogen werden, ist es möglich aufeinanderfolgende Stützteile 26 mit etwas verschiedenen ausgerichteten Längsrichtungen anzuordnen, sodass die seitliche Stütze Wegkrümmungen folgen kann.Since slope crossings of footpaths often extend over long distances, it is necessary to arrange several support parts 26 in a row along a footpath. So that neighboring support parts 26 can be easily linked together, they are preferably arranged as in Fig.10 visibly provided on the front side with a tab 28 which is penetrated by screw through holes 29. Both front sides of a support part 26 are each provided with a tab 28, and the surface of a tab preferably extends normal to the longitudinal direction of the support part 26 into the cross-sectional area of the channel delimited by the base surface 2 and the flank surfaces 7. For the longitudinal connection of two support parts 26, the front sides of the two support parts which are arranged facing one another can be connected simply by screws and associated nuts, with the screws extending through the screw through holes 29 which are aligned with one another in the two adjacent tabs 28 of the two support parts 26. By choosing a screw diameter smaller than the diameter of the screw through holes 29 and by not tightening the screw connections, it is possible to arrange successive support parts 26 with slightly different longitudinal directions so that the lateral support can follow path curves.

Auch wenn ein Stützteil 26 zufolge der Laschen 28 nicht mehr durch Stanzen und Rollformen eines Blechbandes allein in seine Form, gebracht werden kann, ist er immer noch sehr kostengünstig herstellbar, da die erforderlichen Umformvorgänge nur einfache Kantungen sind.Even if a support part 26 can no longer be brought into its shape by punching and roll forming a sheet metal strip alone due to the tabs 28, it can still be manufactured very cost-effectively, since the required forming processes are only simple bending.

Fig. 11 dient zur Beschreibung sowohl der üblichen Einbausituation als auch einer besonderen Einbausituation eines Stützteils 26 wenn dieser als Stützteil einer Stufe an der Seite eines Gehweges angewandt wird. Fig. 11 serves to describe both the usual installation situation and a special installation situation of a support part 26 when it is used as a support part of a step on the side of a walkway.

In der typischen Einbausituation ist eine Stützteil 26 so wie zuvor an den Stützteilen 1, 8, 21 beschrieben einfach nur durch Spieße 9 gehalten, welche im Untergrundmaterial 10 stecken, und durch Durchbrüche 4 in der ersten (unteren) Flankenfläche 3 hindurch nach oben ragen, und an der Innenseite der an die Flankenfläche 3 anschließenden Einfassungsfläche 7 anliegen.In the typical installation situation, a support part 26 is held as previously described on the support parts 1, 8, 21 simply by spikes 9 which are inserted into the substrate material 10 and protrude upwards through openings 4 in the first (lower) flank surface 3 and rest against the inside of the edging surface 7 adjoining the flank surface 3.

In dem in Fig. 11 skizzierten besonderen Fall, dass der Hang 30, welcher durch den Gehweg 31 gequert wird, sehr steil und/oder sehr instabil ist, ist wie dargestellt eine zusätzliche Befestigung vorteilhaft:
Ein. Spieß 9, welcher wie zuvor erwähnt durch einen Durchbruch 4 des Stützteils 26 hindurch ragt, ragt unterhalb des Stützteils 26 auch durch einen Durchbruch 32 eines als "Queranker" 33 bezeichneten Teils, welcher ein langgestreckter Teil ist, der sich unterhalb der Gehfläche 34 von der talseitigen Wegseite zur bergseitigen Wegseite hin erstreckt. Der Queranker 33 ist durch einen oder mehrere weitere Spieße 35 gegen Verrutschen zur Talseite des Gehweges 31 hin gehalten. Dazu erstrecken sich die weiteren Spie-βe 35 durch, vertikal ausgerichtete weitere Durchbrücke im Queranker 33 hindurch in das Untergrundmaterial 10. Zur Gehfläche 34 hin sind der der Queranker 33 und die weiteren Spieße 35 durch Untergrundmaterial zugedeckt. Durch diese Bauweise ist jener Spieß 9, welcher mit dem Stützteil 26 in direktem Kontakt ist, extrem gut gegen Bewegung zur Talseite des Gehweges 31 hin gehalten.In the Fig. 11 In the special case outlined above, where the slope 30, which is crossed by the walkway 31, is very steep and/or very unstable, an additional reinforcement is advantageous as shown:
A spike 9, which as previously mentioned protrudes through an opening 4 in the support part 26, also protrudes below the support part 26 through an opening 32 in a part referred to as a "cross anchor" 33, which is an elongated part that extends below the walking surface 34 from the valley side of the path to the mountain side of the path. The cross anchor 33 is held against slipping towards the valley side of the walkway 31 by one or more further spikes 35. For this purpose, the further spikes 35 extend through a vertically aligned further opening in the cross anchor 33 into the subsurface material 10. Towards the walking surface 34, the cross anchor 33 and the further spikes 35 are covered by subsurface material. Due to this design, the spike 9, which is in direct contact with the support part 26, is extremely well held against movement towards the valley side of the walkway 31.

Optional kann - wie dargestellt - der Queranker 33 einen Längsbereich 36 aufweisen, welcher auf der vom Gehweg 31 abgewandten Seite unter dem Stützteil 26 hervorragt und einen Durchbruch 37 aufweist, durch welchen im Bedarfsfall ein Steher für ein Geländer oder einen Handlauf in das Untergrundmaterial 10 durchführbar ist. Dieser Steher ist dann auch durch den Queranker 33 gut gegen Seitwärtsbewegung zur Talseite hin gehalten.Optionally - as shown - the cross anchor 33 can have a longitudinal area 36 which protrudes from under the support part 26 on the side facing away from the walkway 31 and has an opening 37 through which, if necessary, a post for a railing or a handrail can be passed into the subsurface material 10. This post is then also well held against sideways movement towards the valley side by the cross anchor 33.

Der Queranker 33 braucht übrigens nicht als ein einziger in sich monolithischer Teil ausgebildet zu sein. Er kann auch aus mehreren wahlweise miteinander zu verbindenden Einzelteilen aufgebaut sein, womit er modulartig an verschiedene Anforderungen anpassbar ist.The cross anchor 33 does not have to be designed as a single monolithic part. It can also be constructed from several individual parts that can be optionally connected to one another, which means that it can be adapted to different requirements in a modular manner.
