Zwecks Höhenverstellbarkeit ist ein mittlerer Teil (3) sowohl mit einem unteren Teil (2) als auch mit einem oberen Teil (4) in Gewindeverbindung, wobei die beiden Gewindeverbindungen zueinander entgegengesetzt drehend ausgebildet sind. Zwecks Neigungsverstellbarkeit sind einander berührende Oberflächen zweier Teile (1, 3) als innereinander liegende Teilkugelflächen (6, 10) ausgebildet, die mittels einer Schraubverbindung aneinander festklemmbar sind. Die beiden Gewinde des mittleren Teils (3) sind als koaxial zueinander liegende, sich in ihrer Längsausdehnung einander überlappende Mutter- und Bolzengewinde ausgebildet. Ein Gewinde des mittleren Teils (3) ist auch Teil jener Schraubverbindung, mit Hilfe derer die beiden an den Teilkugelflächen (6, 10) aneinander liegenden Teile (1, 3) aneinander festklemmbar sind.The invention relates to a height and tilt-adjustable support foot used for carrying a part of a building. For height adjustment is a middle part (3) with both a lower part (2) and with an upper part (4) in threaded connection, wherein the two threaded connections are formed opposite to each other in rotation. For the purpose of inclination adjustability, mutually contacting surfaces of two parts (1, 3) are formed as part spherical surfaces (6, 10) lying in each other, which can be clamped to one another by means of a screw connection. The two threads of the central part (3) are formed as mutually coaxial with each other, in their longitudinal extent overlapping nut and bolt thread. A thread of the middle part (3) is also part of that screw connection by means of which the two parts (1, 3) abutting one another on the part ball surfaces (6, 10) can be clamped to one another.

Description

Die Erfindung betrifft einen höhen- und neigungsverstellbaren Stützfuß für Teile von Bauwerken.The invention relates to a height and tilt adjustable support foot for parts of buildings.

Ein sehr typischer beispielhafter Anwendungsfall für einen erfindungsgemäßen Stützfuß ist es, eine Holzsäule eines Bauwerks wie beispielsweise eines Carports oder eines Schuppens, zu tragen und zum Untergrund hin abzustützen.A very typical exemplary application for a support leg according to the invention is to carry a wooden pillar of a structure such as a carport or a shed, and to support it to the ground.

Unter anderem die DE 4424229 A1 und die GB 2111553 A zeigen einen Erdanker mit einer oben daran anschließenden schwenkbaren Halterung für Elemente wie Pfähle oder Säulen. Die Schwenkbarkeit der Halterung ist realisiert, indem der oberste Oberflächenbereich des Erdankers und der unterste Oberflächenbereich der Halterung als innereinander liegende, zur gleichen Richtung hin (nach oben oder nach unten hin) offene Teilkugelflächen ausgebildet sind, die um ihren gemeinsamen Kugelmittelpunkt gegeneinander verschiebbar sind und wahlweise mittels einer Schraube, die durch eine Öffnung in beiden Teilkugelflächen durchgeht, aneinander festgeklemmt werden können. Ein erheblicher Nachteil an der Bauweise ist, dass die Schraube nach der Montage der ggf. angebrachten Säule nicht mehr zugänglich ist, und damit die Neigung der Säule nicht bei aufgestellter Säule korrigierbar ist.Among other things the DE 4424229 A1 and the GB 2111553 A show a ground anchor with a pivoting support for elements such as piles or columns. The pivoting of the holder is realized by the uppermost surface region of the ground anchor and the lowermost surface region of the holder are formed as one inside, towards the same direction (up or down) open part spherical surfaces which are mutually displaceable about their common sphere center and optionally by means of a screw which passes through an opening in both partial spherical surfaces, can be clamped together. A significant disadvantage of the construction is that the screw after installation of the possibly attached column is no longer accessible, and thus the inclination of the column is not correctable when erected column.

Die DE 20 2011 052 381 U1 , zeigt für einen an einer Betonfläche zu verankernden Pfostenträger das gleiche Verstellungsprinzip wie die DE 4424229 A1 und die GB 2111553 A . Es führt auch zum gleichen Nachteil.The DE 20 2011 052 381 U1 , shows for a to be anchored to a concrete surface post carrier the same adjustment principle as the DE 4424229 A1 and the GB 2111553 A , It also leads to the same disadvantage.

Die DE 7611146 U1 zeigt eine klassische Bauweise für einen höhenverstellbaren aber nicht neigungsverstellbaren Stützfuß für das Abstützen von Elementen eines Fußbodens gegenüber einer deutlich tiefer liegenden Gebäudefläche. Der Stützfuß weist von unten nach oben folgend einen Bodenteil, einen Mittelteil und einen Oberteil auf. Der Bodenteil weist einen nach oben ragenden Gewindebolzen auf und der Oberteil einen nach unten ragenden Gewindebolzen mit zur Drehrichtung des unteren Gewindebolzens entgegengesetzter Drehrichtung auf. Der Mittelteil ist eine vertikal ausgerichtete Gewindehülse, bei der die Drehrichtung des Mutterngewindes im oberen Längsbereich entgegengesetzt ist zur Drehrichtung des Mutterngewindes im unteren Längsbereich. Die zuvor genannten Gewindebolzen sind mit diesen Mutterngewinden in Gewindeeingriff. Wird der als Gewindehülse ausgeführte Mittelteil um die Gewindeachse relativ zu Oberteil und Unterteil gedreht, so vergrößert oder verkleinert sich die Gesamthöhe des Stützfußes. Die Höhenänderung pro Umdrehung des Mittelteils beträgt zwei Ganghöhen des Gewindes, also doppelt so viel wie bei üblichen Schraubvorgängen. Das kann beim Anheben gegen schweren Gegendruck oder beim Feineinstellen der Höhe unter Last empfindlich stören.The DE 7611146 U1 shows a classic design for a height-adjustable but not tilt-adjustable support leg for supporting elements of a floor compared to a much lower building surface. The support foot has from bottom to top following a bottom part, a middle part and a top. The bottom part has an upwardly projecting threaded bolt on and the upper part of a downwardly projecting threaded bolt with the direction of rotation of the lower threaded bolt opposite direction of rotation. The middle part is a vertically oriented threaded sleeve, in which the direction of rotation of the nut thread in the upper longitudinal region is opposite to the direction of rotation of the nut thread in the lower longitudinal region. The aforementioned threaded bolts are threadedly engaged with these nut threads. If the middle part designed as a threaded sleeve is rotated about the thread axis relative to the upper part and lower part, then the overall height of the support foot is increased or decreased. The height change per revolution of the middle part is two pitches of the thread, which is twice as much as with conventional screwing. This can be annoying when lifting against heavy back pressure or when fine tuning the height under load.

Die DE 202010010737 U1 zeigt einen höhen- und neigungsverstellbaren Stützfuß für Fußbodenelemente gegenüber einer darunterliegenden Gebäudefläche. Der Stützfuß weist von unten nach oben folgend einen Bodenteil, einen Mittelteil und einen Oberteil auf. Der Bodenteil weist einen nach oben ragenden Gewindebolzen auf. Der aus zwei um eine horizontale Achse gegeneinander schwenkbaren Teilen gebildete Oberteil weist eine nach unten ragende Gewindehülse mit zur Drehrichtung des unteren Gewindebolzens entgegengesetzter Drehrichtung auf. Der Mittelteil ist dazu komplementär im oberen Bereich als Gewindebolzen und im unteren Bereich als Gewindehülse ausgebildet dessen beide Gewinde mit den Gewindeteilen des Ober- und Unterteils in Gewindeeingriff sind. Die Höhenänderung pro Umdrehung des Mittelteils beträgt wiederum zwei Ganghöhen des Gewindes, also doppelt so viel wie bei üblichen Schraubvorgängen. Bezogen auf seinen Höhenverstellbereich ist der Stützfuß relativ hoch. Es erfordert einiges handwerkliches Geschick, die o. g. horizontale Achse passend auszurichten ohne dabei die Höhe des Stützfußes unpassend zu verändern.The DE 202010010737 U1 shows a height and tilt adjustable support foot for floor elements opposite an underlying building surface. The support foot has from bottom to top following a bottom part, a middle part and a top. The bottom part has an upwardly projecting threaded bolt. The upper part formed from two parts pivotable about a horizontal axis relative to each other has a downwardly projecting threaded sleeve with opposite direction of rotation to the direction of rotation of the lower threaded bolt. The middle part is complementary to the upper part as a threaded bolt and formed in the lower part of a threaded sleeve whose two threads are threadedly engaged with the threaded parts of the upper and lower parts. The change in height per revolution of the middle part is again two pitches of the thread, so twice as much as in conventional screwing. Relative to its height adjustment range, the support foot is relatively high. It takes some manual skill to align the above-mentioned horizontal axis without unduly changing the height of the support leg.

Die EP 0309399 A1 und die DE 19631231 A1 zeigen Stützfüße für einen Doppelboden. Ein Teller, auf welchen der obere Boden von oben her aufzulegen ist, ist als Teilkugelschale ausgebildet, welche an einer Teilkugelschale eines Mittelteiles neigungseinstellbar von oben her anliegt und daran mittels einer von der Oberseite des Tellers her einzuschraubenden Schraube fixierbar ist. Der Mittelteil ist dazu als Gewindehülse mit Außengewinde und Innengewinde ausgebildet, wobei das Außengewinde zur Höhenverstellung gegenüber einem unteren Teil dient und wobei die beiden genannten Gewinde in die gleiche Drehrichtung gängig sind.The EP 0309399 A1 and the DE 19631231 A1 show support feet for a raised floor. A plate on which the upper floor is to hang from above, is formed as a part ball shell, which abuts a partial ball shell of a central part tilt adjustable from above and can be fixed thereto by means of a screwed from the top of the plate ago screw. The middle part is for this purpose designed as a threaded sleeve with external thread and internal thread, wherein the external thread for height adjustment relative to a lower part is used and wherein the two said threads are common in the same direction of rotation.

Die der Erfindung zu Grunde liegende Aufgabe besteht darin, einen Stützfuß vor allem für das Abstützen des unteren Endes einer Holzsäulen gegenüber einer Bauwerksfläche wie z.B. einer Rohdecke oder einem Fundament zu schaffen, welcher höhen- und neigungsverstellbar ist um Ungenauigkeiten in der Bauwerksfläche ausgleichen zu können. Gegenüber der aus der DE 202010010737 U1 dazu bekannten Bauweise soll der zu schaffende Stützfuß leichter einjustierbar sein und bezogen auf den Höhenverstellbereich kleiner sein können.The object underlying the invention is to provide a support foot especially for supporting the lower end of a wooden columns against a building surface such as a raw ceiling or a foundation, which is adjustable in height and tilt to compensate for inaccuracies in the building area can. Opposite from the DE 202010010737 U1 known construction to be created support foot should be easier einjustierbar and related to the height adjustment can be smaller.

Für das Lösen der Aufgabe werden die aus dem besprochenen Stand der Technik zumindest getrennt voneinander verwerdeten Merkmale übernommen, dass

  • eine Höhenverstellungsbaugruppe von unten nach oben folgend einen unteren, einen mittleren und einen oberen Teil aufweist, wobei der mittlere Teil sowohl mit dem unteren als auch mit dem oberen Teil in Gewindeeingriff ist, und wobei die Drehrichtung des Gewindes zwischen dem mittleren Teil und dem oberen entgegengesetzt zur Drehrichtung des Gewindes zwischen dem mittleren Teil und dem unteren Teil ist,

Als erfindungsgemäße Weiterentwicklung dazu wird vorgeschlager dass

  • die beiden Gewinde des mittleren Teils der Höhenverstellungsbaugruppe als zueinander koaxiale, sich in ihrer Längsrichtung überlappende, Mutter- und Bolzengewinde ausgebildet sind,
  • und dass eines der beiden Gewinde des mittleren Teils der Höhenverstellungsbaugruppe auch Gewinde jener Schraubverbindung ist, mit Hilfe derer die beiden Teilkugelflächen der Neigungsverstellungsbaugruppe aneinander festgeklemmt werden können.

Zur Veranschaulichung der Erfindung zeigt Fig. 1 zeigt in seitlicher Schnittansicht die für das Verständnis der Erfindung relevanten Teile einer beispielhaften vorteilhaften Ausführung eines erfindungsgemäßen Stützfußes.To illustrate the invention shows Fig. 1 shows a side sectional view of the relevant to the understanding of the invention parts of an exemplary advantageous embodiment of a support leg according to the invention.

Die statisch relevanten Teile des Stützfußes von Fig. 1 gereiht von unten nach oben sind ein Bodenteil 1, eine Schraube 2, ein Mittelteil 3 und ein Oberteil 4.The statically relevant parts of the support leg of Fig. 1 ranked from bottom to top are a bottom part 1, a screw 2, a middle part 3 and an upper part. 4

Der flächige Bodenteil 1 besteht typischerweise aus einem starken Stahlblech (beispielsweise 8 mm stark). Bei bestimmungsgemäßen Einbau liegt der Bodenteil 1 auf dem Untergrund, typischerweise auf einer Rohdecke oder einem betonierten Fundament oben auf und ist dort mittels Schrauben die durch Schraubendurchgangsbohrungen 5 verlaufen und im Untergrund verankert sind, fixiert.
In seiner Flächenmitte ist der Bodenteil 1 zu einer Erhebung nach oben geprägt, deren obere Oberfläche die Form einer nach unten offenen Teilkugelfläche 6 hat, welche von einer mittleren vertikalen Schraubendurchgangsbohrung 7 durchbrochen ist.The flat bottom part 1 typically consists of a strong steel sheet (for example, 8 mm thick). When installed as intended, the bottom part 1 is located on the ground, typically on a raw ceiling or a concrete foundation on top and is there by means of screws which run through Schraubendurchgangsbohrungen 5 and anchored in the ground, fixed.
In its center of the surface of the bottom part 1 is embossed up to a collection, the upper surface has the shape of a downwardly open part spherical surface 6, which is broken by a central vertical screw through hole 7.

Die Schraube 2, welche einen sechskantförmigen Schraubenkopf 8 und einen Gewindebolzens 9 aufweist, ragt mit einem deutlichen Spiel durch die Schraubendurchgangsbohrung 7 hindurch mit ihrem Gewindebolzen 9 voran nach oben. Der gegenüber dem Gewindebolzen 9 verbreiterte sechskantförmige Schraubenkopf 8, befindet sich in dem durch die Erhebung unterhalb der Teilkugelfläche 6 überdachten Hohlraum und liegt von unten her an den Rändern der Schraubendurchgangsbohrung 7 an.The screw 2, which has a hexagonal screw head 8 and a threaded bolt 9, projects with a clear play through the screw through hole 7 through with its threaded bolt 9 upwards. The relative to the threaded bolt 9 widened hexagonal screw head 8, located in the area covered by the survey below the part spherical surface 6 cavity and is located from below at the edges of the screw through hole 7 at.

Der Mittelteil 3 ist im Wesentlichen ein senkrecht stehender Gewindebolzen, dessen unteren Stirnfläche als nach unten offene Teilkugelfläche 10 ausgebildet ist, die auf der zum Bodenteil 1 gehörenden Teilkugelflächen 6 oben aufliegt und die zumindest etwa den gleichen Kugelmittelpunkt hat wie die Teilkugelflächen 6.
Von der unteren Stirnseite des Mittelteils 3 her führt eine Gewindebohrung 11 nach oben. In montiertem Zustand ist in diese Gewindebohrung 11 der Gewindebolzen 9 der Schraube 2 so tief eingeschraubt dass die als Teilkugelfläche 10 ausgebildete untere Stirnfläche des Mittelteils 3 von oben her an die Teilkugelfläche 6 des Bodenteils 1 gedrückt wird und der Schraubenkopf 8 von unten her an den Bodenteil 1, womit der Mittelteil 3 am Bodenteil 1 starr fixiert ist.The middle part 3 is essentially a vertical threaded bolt whose lower end face is designed as a downwardly open part spherical surface 10 which rests on the part 1 belonging to the bottom part spherical surfaces 6 above and at least about the same ball center as the part spherical surfaces. 6
From the lower end side of the middle part 3 ago leads a threaded bore 11 upwards. In the assembled state, the threaded bolt 9 of the screw 2 is screwed into this threaded hole 11 so deep that the partial spherical surface 10 formed lower end face of the central part 3 is pressed from above to the part spherical surface 6 of the bottom part 1 and the screw head 8 from below to the bottom part 1, whereby the middle part 3 is rigidly fixed to the bottom part 1.

Der Oberteil 4 ist an seinem nicht dargestellten oberen Bereich mit der zu tragenden Säule verbunden. Diese weitere Verbindung, für die es viele Realisierungsmöglichkeiten gibt (zentrale Schraubverbindung, Steckverbindung, Flanschverbindung mit einem Kranz von Schrauben, Klemmen.....), ist nicht Teil der Erfindung.
In seinem überwiegenden unterhalb des Verbindungsbereiches mit der Säule liegenden Längsbereich ist der Oberteil 4 eine Gewindehülse 12, deren Mutterngewinde 13 von oben her auf das Außengewinde 14 des Mittelteils 3 aufgeschraubt ist und somit mit diesem in Gewindeeingriff ist. Je nachdem wie weit das Mutterngewinde 13 des Oberteils 4 aufgeschraubt ist, ist die Gesamtlänge aus Mittelteil 3 und Oberteil 4 kürzer oder länger und damit der Stützfuß niedriger oder höher.The upper part 4 is connected at its upper portion, not shown, with the column to be supported. This further connection, for which there are many possibilities of realization (central screw connection, plug connection, flange connection with a wreath of screws, clamps .....), is not part of the invention.
In its predominant below the connection region with the column longitudinal region of the upper part 4 is a threaded sleeve 12, the nut thread 13 is screwed from above onto the external thread 14 of the central part 3 and thus is in threaded engagement with this. Depending on how far the nut thread 13 of the upper part 4 is screwed, the total length of middle part 3 and top 4 shorter or longer, and thus the support foot lower or higher.

Eine kreiszylinderförmige Hülse 15 umringt die Gewindehülse 12 des Oberteils 4 zumindest in deren unteren Bereich in einer lockeren Spielpassung. Die Hülse 15 bewirkt einen Schutz vor Bewitterung und damit Korrosion von empfindlichen Bereichen des Stützfußes, und sie hat optische Funktion. Indem sie den Übergangsbereich zwischen dem Bodenteil 1 und den daran oben anschließenden statisch tragenden Teilen 3, 4 abdeckt, bewirkt sie eine ebenmäßige Optik des Stützfußes.A circular cylindrical sleeve 15 surrounds the threaded sleeve 12 of the upper part 4 at least in the lower region in a loose clearance fit. The sleeve 15 provides protection against weathering and thus corrosion of sensitive areas of the support leg, and it has an optical function. By covering the transition region between the bottom part 1 and the static supporting parts 3, 4 adjoining above, it effects a uniform appearance of the support foot.

Ein Montagevorgang des gezeigten erfindungsgemäßen Stützfußes kann die folgenden zeitlich hintereinander gereihten Arbeitsschritte umfassen:

  • Bei nur lose angezogener Schraube 2 und tief auf den Mittelteil 3 aufgeschraubten Oberteil 4 wird der Stützfuß an Einsatzort aufgestellt und mittels Schrauben die durch die Schraubendurchgangsbohrungen 5 hindurch verlaufen, fixiert.
An assembly process of the illustrated support leg according to the invention can comprise the following work steps, arranged one behind the other:
  • When only loosely tightened screw 2 and deeply screwed onto the middle part 3 upper part 4 of the support foot is placed at the place of use and by means of screws which pass through the screw through holes 5, fixed.

Dann wird die gemeinsame Achse von Mittelteil 3 und Oberteil 4 vertikal ausjustiert, indem am Oberteil 4 in die passende Richtung seitlich ausreichend stark gedrückt wird, um den Schraubenkopf 8 der Schraube 2 an der Unterseite der Erhebung am Bodenteils 1 etwas zu verschieben. Nach dem Ausrichten der Achse wird der Mittelteil 3 am Bodenteil 1 stärker fixiert, indem der Mittelteil 3 bei angehobener Hülse 15 an seinem unteren Endbereich, welcher eine Eingriffsgeometrie für einen Schraubenschlüssel aufweisen kann, gefasst und etwas so gedreht wird, dass die Schraube 2, die durch Reibung des Schraubenkopfes 8 am Bodenteil 1 unbeweglich ist, tiefer in die Gewindebohrung 11 eingeschraubt wird. Als nächstes wird die Höhe des Stützfußes einjustiert indem der Oberteil 4 um die gemeinsame Achse gegenüber dem Mittelteil 3 gedreht wird und somit nach oben geschraubt wird bis der Stützfuß die passende Höhe hat. Für den Eingriff eines Schraubwerkzeuges kann beispielsweise die Gewindehülse 12 an ihrem oberen oder unteren Endbereich mit einer zum Werkzeug passenden Eingriffsgeometrie versehen sein.
Damit sich beim Drehen des Oberteils 4 zum Zwecke des Schraubens nach oben nicht der Mittelteil 3 mit dreht, womit die Schraubverbindung durch die Schraube 2 gelockert werden würde, sind die beiden Gewindeverbindungen des Mittelteils 3 in entgegengesetzte Richtungen drehend ausgebildet. D.h. wenn die Schraube 2 und die zugehörige Gewindebohrung 11 ein Linksgewinde aufweisen, müssen das Mutterngewinde 13 der Gewindehülse 12 des Oberteils 4 und das zugehörige Außengewinde 14 des Mittelteils 3 Rechtsgewinde sein.Then, the common axis of the middle part 3 and upper part 4 is vertically adjusted by the upper part 4 in the appropriate direction is pressed laterally strong enough to move the screw head 8 of the screw 2 at the bottom of the survey on the bottom part 1 something. After aligning the axis of the central part 3 is fixed to the bottom part 1 stronger by the middle part 3 with raised sleeve 15 at its lower end portion, which may have a meshing geometry for a wrench, taken and slightly rotated so that the screw 2, the is immovable by friction of the screw head 8 on the bottom part 1, is screwed deeper into the threaded hole 11. Next, the height of the support leg is adjusted by the upper part 4 is rotated about the common axis relative to the central part 3 and thus screwed up until the support leg has the appropriate height. For the intervention of a screwing tool For example, the threaded sleeve 12 may be provided at its upper or lower end portion with a matching engagement geometry to the tool.
So that when turning the upper part 4 for the purpose of screwing up not the central part 3 rotates, whereby the screw connection would be loosened by the screw 2, the two threaded connections of the central part 3 are designed to rotate in opposite directions. That is, when the screw 2 and the associated threaded bore 11 have a left-hand thread, the nut thread 13 of the threaded sleeve 12 of the upper part 4 and the associated external thread 14 of the middle part 3 must be right-hand thread.

Indem für das Höhenverstellen des Stützfußes nur der Oberteil 4 und nicht wie bei Bauweisen beim Stand der Technik der Mittelteil 3 gedreht wird, wird nur an einer Gewindeverbindung gedreht und damit verändert sich pro Umdrehung die Höhe nur um eine Ganghöhe eines Gewindes und nicht die addierten Ganghöhen zweier Gewinde. Das wirkt sich auf Leichtigkeit und Feinheit der Einstellbarkeit vorteilhaft aus.
Indem die Verschraubung zwischen Mittelteil 3 und Bodenteil 1 immer ganz angezogen ist, ist sie eine einfache und höhensparende Möglichkeit für das notwendige Fixieren der Klemmung zwischen den der Neigungsverstellung dienenden Teilkugelflächen an Mittelteil 3 und Bodenteil 1. Indem sich die beiden Gewinde am Mittelteil 3 nämlich das Mutterngewinde in der Gewindebohrung 11 und Außengewinde 14 am Mittelteil 3, in ihrer Länge überlappen, geht gegenüber Bauweisen bei denen am Mittelteil gedreht wird und sich die beiden Gewinde des Mittelteils im Längsbereich nicht überlappen, bezogen auf die Höhe des Mittelteils kein Einstellbereich verloren.By only the upper part 4 is rotated for height adjustment of the support leg and not as in the prior art construction of the center part 3, is rotated only at a threaded connection and thus changes per turn, the height only by a pitch of a thread and not the added pitches two threads. This has an advantageous effect on ease and fineness of adjustability.
By the screw connection between the middle part 3 and the bottom part 1 is always fully tightened, it is a simple and height-saving way for the necessary fixing the clamping between the pitch adjustment serving part ball surfaces at middle part 3 and bottom part 1. By the two threads on the central part 3 namely the Nut thread in the threaded bore 11 and external thread 14 on the central part 3, overlap in length, is opposite to construction in which the middle part is rotated and the two threads of the middle part in the longitudinal region do not overlap, based on the height of the middle part no adjustment lost.

Insbesondere bei der Anwendung an Carports ist die Neigungsverstellbarkeit der aufrechten Teile des Stützfußes gegenüber dem Bodenteil sehr wichtig, da das Fundament von Carports üblicherweise zumindest leicht geneigt angelegt wird, damit Wasser abfließen kann. Wenn der Stützfuß nicht neigungsverstellbar wäre, würden damit die emporragenden Teile etwas schräg stehen und wären dadurch insbesondere bei Schneelast auf dem Dach des Carports gefährdet weg zu knicken.
Sehr nützlich ist die Neigungsverstellbarkeit auch dann, wenn der Stützfuß auf ein sehr grob betoniertes Fundament gestellt werden muss, welches oberflächliche grobe Unebenheiten aufweist.In particular, when used on carports, the inclination adjustability of the upright parts of the support leg relative to the bottom part is very important because the foundation of carports usually at least slightly inclined, so that water can flow away. If the support leg would not be adjustable in inclination, so that the protruding parts would be slightly sloping and would be endangered especially at snow load on the roof of the carport to bend away.
The inclination adjustability is also very useful if the support foot has to be placed on a very coarse concrete foundation, which has superficial coarse unevenness.
