Definitions

  • the invention relates to a formwork for a prefabricated staircase with a lower formwork part and two lateral and essentially vertical formwork walls with an upper edge.
  • Prefabricated stairs made of hardening, mineral building material, especially concrete, are used in building construction and civil engineering.

  • a formwork suitable for the manufacture of such prefabricated stairs has vertical formwork walls running laterally over the entire length. Furthermore, the formwork has a lower part of the formwork, which has a central, sawtooth-shaped underbody, which forms a negative form of the steps to be produced. Flat sub-floors in the form of an inclined plane connect to this central sub-floor in the longitudinal direction of the formwork, which either extend upwards beyond the step area or downwards to below the step area, depending on whether an upper and/or a lower platform area is also produced shall be.
  • a counter-formwork wall In order to be able to produce a platform area with a constant thickness, a counter-formwork wall must be arranged parallel to the flat sub-floor in the formwork section for the platform area, which, as mentioned, lies at an angle in the formwork.
  • the level of the building material poured into the formwork rises in the downwardly sloping formwork section for the landing area up to the upper edge of the side formwork walls.
  • the formwork section for the platform area which points diagonally upwards, can then also be filled.
  • the invention is therefore based on the object of providing a formwork of the type mentioned at the outset, which can be easily adapted for the production of differently shaped, in particular differently steep and/or long, prefabricated stairs.

Since the counter formwork wall is arranged between the formwork walls, i.e. is inclined downwards between them and does not rest on them, there is the further advantage that an adjustment of lateral formwork walls is not necessary.
  • the opposing formwork wall extends at least to the upper edges of the formwork walls.
  • the lateral formwork walls can have a constant height along the entire formwork and the formwork can be filled with building material up to these upper edges, since the counter formwork wall extends to the upper edges of the lateral formwork walls.
  • the building material that has not yet hardened can simply be pulled off at the top edges to create a smooth surface that will later be the bottom view or underside of the stairs.
  • the step area can also be covered with a counter formwork wall. In such an embodiment, the building material that has not yet hardened does not have to be removed at the upper edges of the formwork in order to produce a smooth surface.

  • an upper edge of the opposing formwork wall is essentially exactly level with the upper edges of the lateral formwork walls, which on the one hand ensures that the formwork cavity can be filled with building material up to the upper edge of the formwork walls and, on the other hand, no area of the opposing formwork wall protrudes in a disruptive manner.
  • An advantageous embodiment of the invention is characterized in that at least one of the joints is a support part, which is arranged on the formwork wall in the area of the upper edge, in particular can be connected to it, and a pivoting part, which is arranged on the opposite formwork wall, in particular connected to it , Having, and that the pivot part is mounted pivotably about the pivot axis on the support part.

Description

Die Erfindung betrifft eine Schalung für eine Fertigtreppe mit einem Schalungsunterteil und zwei seitlichen und im Wesentlichen lotrechten Schalungswänden mit einer Oberkante.The invention relates to a formwork for a prefabricated staircase with a lower formwork part and two lateral and essentially vertical formwork walls with an upper edge.

Im Hoch- und Tiefbau werden Fertigtreppen aus aushärtendem, mineralischen Baustoff, insbesondere Beton, eingesetzt.Prefabricated stairs made of hardening, mineral building material, especially concrete, are used in building construction and civil engineering.

Üblicherweise werden solche Fertigtreppen mit einem Stufenbereich und einem oberen und/oder unteren, daran anschließenden Podestbereich liegend in dafür bereitgestellten Schalungen gegossen bzw. angefertigt. Derartige Schalungen sind beispielsweise aus der CN 1049244425 A und der WO 2008/033037 A1 bekannt.Usually, such prefabricated stairs with a step area and an upper and/or lower, adjoining platform area are cast or manufactured lying in molds provided for this purpose. Such formwork is, for example, from CN 1049244425A and the WO 2008/033037 A1 known.

Weitere Schalungen für Fertigtreppen sind aus CN 206598367 U , DE 197 34 616 A1 , DE 35 18 200 C1 , DE 198 08 770 A1 , CN204935856U , CN204640456U und CN104924424 bekannt.More formwork for prefabricated stairs are out CN 206598367 U , DE 197 34 616 A1 , DE 35 18 200 C1 , DE 198 08 770 A1 , CN204935856U , CN204640456U and CN104924424 known.

Der im eingebauten Zustand der Treppe schräg verlaufende Stufenbereich wird während der Herstellung der Fertigtreppe im Wesentlichen waagrecht liegend gefertigt, wogegen ein an den Stufenbereich anschließender Podestbereich, der im eingebauten Zustand der Treppe waagrecht verläuft, während der Fertigung der Fertigtreppe schräg liegt.The step area, which runs diagonally when the staircase is installed, is manufactured essentially horizontally during the manufacture of the finished staircase, whereas a landing area adjoining the step area, which runs horizontally when the staircase is installed, lies diagonally during the manufacture of the finished staircase.

Eine zur Fertigung solcher Fertigtreppen geeignete Schalung weist zur Seite hin über die gesamte Länge verlaufende, lotrechte Schalungswände auf. Weiters weist die Schalung einen Schalungsunterteil auf, der einen mittleren, sägezahnförmigen Unterboden besitzt, welcher eine Negativform der herzustellenden Stufen bildet. An diesen mittleren Unterboden schließen in Längsrichtung der Schalung flache Unterböden in Form einer schiefen Ebene an, die sich entweder nach oben über den Stufenbereich hinaus oder nach unten bis unterhalb des Stufenbereiches erstrecken, je nachdem, ob auch ein oberer und/oder ein unterer Podestbereich hergestellt werden soll.A formwork suitable for the manufacture of such prefabricated stairs has vertical formwork walls running laterally over the entire length. Furthermore, the formwork has a lower part of the formwork, which has a central, sawtooth-shaped underbody, which forms a negative form of the steps to be produced. Flat sub-floors in the form of an inclined plane connect to this central sub-floor in the longitudinal direction of the formwork, which either extend upwards beyond the step area or downwards to below the step area, depending on whether an upper and/or a lower platform area is also produced shall be.

Um einen Podestbereich mit konstanter Dicke herstellen zu können, muss im Schalungsabschnitt für den Podestbereich, der wie erwähnt schräg in der Schalung liegt, parallel zum flachen Unterboden eine Gegenschalungswand angeordnet werden. Während der Fertigung der Treppe steigt der Pegel des in die Schalung gegossenen Baustoffes in dem nach unten geneigten Schalungsabschnitt für den Podestbereich nach oben bis zur Oberkante der seitlichen Schalungswände. Anschließend kann auch der Schalungsabschnitt für den schräg nach oben weisenden Podestbereich gefüllt werden.In order to be able to produce a platform area with a constant thickness, a counter-formwork wall must be arranged parallel to the flat sub-floor in the formwork section for the platform area, which, as mentioned, lies at an angle in the formwork. During the manufacture of the stairs, the level of the building material poured into the formwork rises in the downwardly sloping formwork section for the landing area up to the upper edge of the side formwork walls. The formwork section for the platform area, which points diagonally upwards, can then also be filled.

Nachteilig an solchen bekannten Schalungen für Fertigtreppen ist, dass insbesondere die Position und die Ausrichtung des Schalungsabschnittes für den schräg nach unten weisenden, also in Einbauposition der Fertigtreppe unteren, Podestbereich in der Schalung nur mit viel Aufwand herstellbar ist, weil eine individuelle Anpassung an unterschiedlich geneigte Podeste mit unterschiedlicher Dicke viel Zeit in Anspruch nimmt und ein großes Fehlerpotential birgt.The disadvantage of such known formwork for prefabricated stairs is that in particular the position and alignment of the formwork section for the platform area in the formwork, which points diagonally downwards, i.e. the lower one in the installed position of the prefabricated staircase, can only be produced with great effort, because an individual adaptation to differently inclined platforms with different thicknesses takes a lot of time and harbors a large potential for errors.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Schalung der eingangs genannten Gattung zur Verfügung zu stellen, welche sich für die Herstellung unterschiedlich geformter, insbesondere unterschiedlich steiler und/oder langer, Fertigtreppen auf einfache Weise adaptieren lässt.The invention is therefore based on the object of providing a formwork of the type mentioned at the outset, which can be easily adapted for the production of differently shaped, in particular differently steep and/or long, prefabricated stairs.

Gelöst wird diese Aufgabe erfindungsgemäß mit einer Schalung, welche die Merkmale des Anspruches 1 aufweist.According to the invention, this object is achieved with a formwork having the features of claim 1 .

Bevorzugte und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the invention are the subject matter of the dependent claims.

Erfindungsgemäß ist vorgesehen, dass die Schalung wenigstens eine zu den Schalungswänden normale, obere Gegenschalungswand, die über Gelenke mit Schwenkachsen an den Schalungswänden verschwenkbar gelagert ist, und die wenigstens teilweise zwischen den Schalungswänden angeordnet ist, aufweist.According to the invention it is provided that the formwork has at least one upper counter-formwork wall which is normal to the formwork walls and which is connected to the formwork walls via joints with pivot axes is pivotably mounted, and which is at least partially arranged between the formwork walls.

Besonders vorteilhaft ist bei der erfindungsgemäßen Schalung, dass die Neigung der Gegenschalungswand für den Podestbereich einfach und schnell verändert bzw. festgelegt werden kann, sodass die Schalung zur Herstellung unterschiedlich steiler Fertigtreppen verwendet werden kann. Da die Gegenschalungswand zwischen den Schalungswänden angeordnet ist, d.h. zwischen diesen nach unten geneigt ist, und nicht auf diesen aufliegt, ergibt sich als weiterer Vorteil, dass eine Anpassung seitlicher Schalungswände nicht erforderlich ist.It is particularly advantageous with the formwork according to the invention that the inclination of the counter formwork wall for the landing area can be changed or fixed easily and quickly, so that the formwork can be used to produce prefabricated stairs of different steepness. Since the counter formwork wall is arranged between the formwork walls, i.e. is inclined downwards between them and does not rest on them, there is the further advantage that an adjustment of lateral formwork walls is not necessary.

Besonders bevorzugt ist bei der Erfindung, wenn die Gegenschalungswand wenigstens bis zu den Oberkanten der Schalungswände reicht. Die seitlichen Schalungswände können entlang der ganzen Schalung eine konstante Höhe aufweisen und die Schalung kann, da die Gegenschalungswand bis zu den Oberkanten der seitlichen Schalungswände reicht, bis zu diesen Oberkanten mit Baustoff gefüllt werden. Der noch nicht ausgehärtete Baustoff kann an den Oberkanten einfach abgezogen werden, um eine glatte Oberfläche herzustellen, die später die Untersicht bzw. Unterseite der Treppe ist. Alternativ kann natürlich auch der Stufenbereich mit einer Gegenschalungswand abgedeckt werden. Bei einer solchen Ausführungsform muss der noch nicht ausgehärtete Baustoff nicht extra an den Oberkanten der Schalung abgezogen werden, um eine glatte Oberfläche herzustellen.In the case of the invention, it is particularly preferred if the opposing formwork wall extends at least to the upper edges of the formwork walls. The lateral formwork walls can have a constant height along the entire formwork and the formwork can be filled with building material up to these upper edges, since the counter formwork wall extends to the upper edges of the lateral formwork walls. The building material that has not yet hardened can simply be pulled off at the top edges to create a smooth surface that will later be the bottom view or underside of the stairs. Alternatively, of course, the step area can also be covered with a counter formwork wall. In such an embodiment, the building material that has not yet hardened does not have to be removed at the upper edges of the formwork in order to produce a smooth surface.

Die vorstehend beschriebenen Ausführungsformen betreffen primär Schalungsabschnitte für nach unten geneigte Podeste. Zusätzlich kann bei der Erfindung auch ein Schalungsabschnitt für nach oben geneigte Podeste verwendet werden, der auch nach oben hin durch eine Gegenschalungswand abgeschlossen ist, womit auf einfache Weise auch ein in der Schalung schräg nach oben ragender Podestbereich hergestellt werden kann, ohne dass der noch nicht ausgehärtete Baustoff extra an den Oberkanten der Schalung abgezogen werden muss, um eine glatte Oberfläche herzustellen.The embodiments described above relate primarily to formwork sections for platforms that are inclined downwards. In addition, a formwork section for platforms that are inclined upwards can also be used with the invention, which is also closed at the top by a counter formwork wall hardened building material has to be removed at the upper edges of the formwork in order to create a smooth surface.

In einer besonders vorteilhaften Ausführungsform sind die Gelenke im Bereich der Oberkanten der Schalungswände angeordnet.In a particularly advantageous embodiment, the joints are arranged in the area of the upper edges of the formwork walls.

Besonders bevorzugt ist, wenn die Gelenke entlang der Oberkanten verstellbar und festlegbar sind. Somit bilden die Oberkanten eine Art horizontale Führung, um die Gegenschalungswand an unterschiedlichen Positionen in der Schalung zu positionieren. Die Schalung kann dadurch an die Herstellung von Fertigtreppen unterschiedlicher Länge und Dicke besonders einfach angepasst werden.It is particularly preferred if the joints can be adjusted and fixed along the upper edges. The upper edges thus form a kind of horizontal guide in order to position the counter formwork wall at different positions in the formwork. As a result, the formwork can be easily adapted to the production of prefabricated stairs of different lengths and thicknesses.

Insbesondere ist bei der Erfindung bevorzugt, wenn die Gelenke Schwenkachsen aufweisen, welche die Oberkanten der Schalungswände schneiden und wenn die Gegenschalungswand wenigstens, vorzugsweise im Wesentlichen genau, bis zur Schwenkachse reicht. Bei dieser Ausführungsform der Erfindung liegt eine Oberkante der Gegenschalungswand im Wesentlichen genau auf Höhe der Oberkanten der seitlichen Schalungswände, womit einerseits gewährleistet ist, dass der Schalungshohlraum bis zur Oberkante der Schalungswände mit Baustoff gefüllt werden kann, und andererseits kein Bereich der Gegenschalungswand störend übersteht.In particular, it is preferred in the invention if the joints have pivot axes which intersect the upper edges of the formwork walls and if the counter formwork wall reaches at least, preferably essentially exactly, up to the pivot axis. In this embodiment of the invention, an upper edge of the opposing formwork wall is essentially exactly level with the upper edges of the lateral formwork walls, which on the one hand ensures that the formwork cavity can be filled with building material up to the upper edge of the formwork walls and, on the other hand, no area of the opposing formwork wall protrudes in a disruptive manner.

Eine vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass wenigstens eines der Gelenke einen Auflageteil, der an der Schalungswand im Bereich der Oberkante angeordnet, insbesondere mit dieser verbindbar, ist, und einen Schwenkteil, der an der Gegenschalungswand angeordnet, insbesondere mit dieser verbunden, ist, aufweist, und dass der Schwenkteil am Auflageteil um die Schwenkachse verschwenkbar gelagert ist.An advantageous embodiment of the invention is characterized in that at least one of the joints is a support part, which is arranged on the formwork wall in the area of the upper edge, in particular can be connected to it, and a pivoting part, which is arranged on the opposite formwork wall, in particular connected to it , Having, and that the pivot part is mounted pivotably about the pivot axis on the support part.

In einer besonders bevorzugten Ausführungsform der Erfindung sind im Bereich der Oberkanten an den seitlichen Schalungswänden in festgelegten Abständen erste Mittel, insbesondere Vertiefungen oder Vorsprünge bzw. Bohrungen oder Zapfen, angeordnet, an denen die Gelenke festlegbar sind. Diese Mittel erleichtern das Positionieren der Gelenke an definierten Punkten der seitlichen Schalungswände.In a particularly preferred embodiment of the invention, first means, in particular depressions or projections or bores or pins, are arranged in the area of the upper edges on the lateral formwork walls at fixed intervals, to which means the joints can be fixed. These means make it easier to position the joints at defined points on the lateral formwork walls.

In Weiterbildung dieser Ausführungsform kann der Auflageteil des Gelenkes wenigstens ein zweites Mittel, insbesondere eine Ausnehmung, vorzugsweise Bohrung, oder einen Vorsprung, vorzugsweise Zapfen, aufweisen, mit dem das Gelenk an der seitlichen Schalungswand festlegbar ist.In a further development of this embodiment, the support part of the joint can have at least one second means, in particular a recess, preferably a bore, or a projection, preferably a pin, with which the joint can be fixed to the lateral formwork wall.

Das erste und zweite Mittel sind beispielsweise gegengleich geformt, z.B. als eine Bohrung an der Oberkante und als ein Zapfen am Auflageteil, und sind aneinander festlegbar bzw. miteinander verbindbar. Dies erlaubt eine sehr einfache und sichere Festlegung der Position des Gelenkes und somit der Gegenschalungswand in Längsrichtung der seitlichen Schalungswand.The first and second means are, for example, shaped in opposite ways, e.g. as a bore on the upper edge and as a peg on the support part, and can be fixed or connected to one another. This allows the position of the joint and thus of the opposing formwork wall to be fixed very easily and securely in the longitudinal direction of the lateral formwork wall.

Alternativ kann auch vorgesehen sein, dass der Auflageteil an der Schalungswand über ein das erste und das zweite Mittel verbindendes, insbesondere durch jeweils eine Ausnehmung im Auflageteil und in der Schalungswand im Bereich der Oberkante geführtes, Verbindungselement, insbesondere einen Bolzen, einen Stift oder eine Schraube, festgelegt ist.Alternatively, it can also be provided that the support part on the formwork wall is connected via a connecting element, in particular a bolt, a pin or a screw, which connects the first and second means and is guided in particular through a recess in the support part and in the formwork wall in the area of the upper edge , is fixed.

Bei der Erfindung kann auch vorgesehen sein, dass zwischen der Schalungswand und dem Auflageteil ein Zwischenteil, insbesondere eine Zwischenleiste, angeordnet ist, das wenigstens ein drittes Mittel, das dem ersten Mittel im Bereich der Oberkante der Schalungswand zugeordnet ist, und wenigstens ein viertes Mittel aufweist, das dem zweiten Mittel am Auflageteil des Gelenkes zugeordnet ist. Das dritte und das vierte Mittel können beispielsweise eine Ausnehmung, insbesondere Bohrung, bzw. einen Vorsprung, vorzugsweise Zapfen, aufweisen. Das dritte und das vierte Mittel können die gleiche oder eine voneinander unterschiedliche Form und Größe aufweisen, beispielsweise Bohrungen mit unterschiedlich großen Durchmessern sein.The invention can also provide for an intermediate part, in particular an intermediate strip, to be arranged between the formwork wall and the support part, which has at least one third means, which is assigned to the first means in the area of the upper edge of the formwork wall, and at least one fourth means , which is associated with the second means on the bearing part of the joint. The third and fourth means can for example a recess, in particular a bore, or a projection, preferably a pin. The third and the fourth means can have the same or a different shape and size, for example bores with different diameters.

Die Form und Zuordnung der ersten und dritten sowie zweiten und vierten Mittel können beispielsweise, aber natürlich nicht zwingend, wie vorstehend zum ersten und zweiten Mittel beschrieben ausgeführt sein. Insbesondere kann der Auflageteil nicht eine Ausnehmung, sondern einen an die Ausnehmung des Zwischenteiles angepassten, beispielsweise zapfen- oder rillenförmigen, Vorsprung aufweisen, mit dem er in einer der Ausnehmungen der Schalungswand angeordnet, insbesondere in diese eingesteckt, ist.The form and allocation of the first and third as well as second and fourth means can, for example, but of course not necessarily, be implemented as described above for the first and second means. In particular, the support part may not have a recess, but rather a projection, for example pin-shaped or groove-shaped, adapted to the recess of the intermediate part, with which it is arranged in one of the recesses of the formwork wall, in particular inserted into it.

Durch Variieren des Abstandes zwischen drittem und viertem Mittel an der Zwischenleiste kann die Position der Gegenschalungswand an den Schalungswänden in Längsrichtung der Schalung exakt festgelegt werden.The position of the opposing formwork wall on the formwork walls in the longitudinal direction of the formwork can be precisely determined by varying the distance between the third and fourth means on the intermediate bar.

In einer alternativen Ausführungsform der Erfindung kann die Schalungswand im Bereich der Oberkante mit dem Zwischenteil über ein das erste und das dritte Mittel verbindendes, insbesondere durch jeweils eine Ausnehmung der Schalungswand und des Zwischenteiles geführtes, erstes Verbindungselement, insbesondere einen Bolzen, einen Stift oder eine Schraube, verbunden werden. Weiters kann der Auflageteil mit dem Zwischenteil über ein durch jeweils eine Ausnehmung des Auflageteiles und des Zwischenteiles geführtes zweites Verbindungselement, insbesondere einen Bolzen, einen Stift oder eine Schraube, verbunden werden.In an alternative embodiment of the invention, the formwork wall can be connected to the intermediate part in the area of the upper edge via a first connecting element, in particular a bolt, a pin or a screw, which connects the first and third means and is guided in particular through a recess in the formwork wall and the intermediate part , get connected. Furthermore, the support part can be connected to the intermediate part via a second connecting element, in particular a bolt, a pin or a screw, which is guided through a respective recess in the support part and the intermediate part.

Besonders vorteilhaft an der Verwendung des Zwischenteiles, insbesondere der Zwischenleiste, ist, dass das Gelenk vor Ort sehr einfach an der richtigen Stelle entlang der Schalungswand positioniert werden kann, indem die bereits mit den passenden Ausnehmungen versehene Zwischenleiste lediglich zwischen der Schalungswand und dem Gelenk angeordnet und mit diesen verbunden wird. Somit wird die Gefahr, dass das Gelenk durch Ungenauigkeit seitens des Bedienpersonales vor Ort an einer falschen Position festgelegt wird, verringert. Die Ausnehmungen an der Schalungswand können dabei für eine Grobeinstellung so weit voneinander beabstandet sein, dass sofort auffällt, wenn das Gelenk falsch positioniert wird.What is particularly advantageous about the use of the intermediate part, in particular the intermediate strip, is that the joint can be very easily installed on site at the right point along the formwork wall can be positioned by merely arranging and connecting the spacer strip, which is already provided with the appropriate recesses, between the formwork wall and the joint. This reduces the risk of the joint being fixed in an incorrect position on site due to inaccuracy on the part of the operating personnel. The recesses on the formwork wall can be spaced so far apart for a rough adjustment that it is immediately apparent when the joint is incorrectly positioned.

Durch die Verwendung des Zwischenteiles bzw. durch den Abstand der am Zwischenteil angeordneten Mittel, beispielsweise Bohrungen, zum Verbinden des Zwischenteils mit der Schalungswand einerseits und dem Gelenk andererseits, kann die Position des Gelenkes an der Schalungswand in weiterer Folge genau eingestellt werden.By using the intermediate part or by the spacing of the means arranged on the intermediate part, for example bores, for connecting the intermediate part to the formwork wall on the one hand and the joint on the other hand, the position of the joint on the formwork wall can subsequently be precisely adjusted.

Besonders vorteilhaft ist es, wenn der Schwenkteil am Auflageteil seitlich außerhalb der Schalungswände angeordnet ist, und die Oberkante von oben umgreift, weil der Schwenkteil dadurch die Anordnung und insbesondere die flexible Einstellbarkeit der Gegenschalungswand zwischen den Seitenwänden nicht behindert.It is particularly advantageous if the pivoting part on the support part is arranged laterally outside the formwork walls and encompasses the top edge from above, because the pivoting part does not impede the arrangement and in particular the flexible adjustability of the counter formwork wall between the side walls.

Fig. 1 zeigt eine erfindungsgemäße Schalung 1 in isometrischer Ansicht, wobei die Schalung 1 lotrechte, seitlich Schalungswände 2 mit Oberkanten 8 aufweist, und wobei die Schalungswände 2 oberhalb und entlang eines Schalungsunterteiles 3 angeordnet sind. Am Schalungsunterteil 3 und zwischen den Schalungswänden 2 ist zumindest abschnittsweise ein mittlerer, sägezahnförmiger Unterboden 4 angeordnet, der einen Innenraum bzw. 1 shows a formwork 1 according to the invention in an isometric view, the formwork 1 having vertical formwork walls 2 with upper edges 8 on the sides, and the formwork walls 2 being arranged above and along a lower formwork part 3 . A central, sawtooth-shaped underbody 4 is arranged at least in sections on the formwork lower part 3 and between the formwork walls 2, which forms an interior space or

Schalungshohlraum der Schalung 1 nach unten begrenzt. Durch die Höhe, in der diese mittlere Unterboden 4 in der Schalung 1 eingebaut wird, bzw. den Abstand des mittleren Unterbodens 4 von der Oberkante 8, kann die Dicke des Stufenabschnittes der Fertigtreppe eingestellt werden.Formwork cavity of the formwork 1 limited downwards. The thickness of the step section of the finished staircase can be adjusted by the height at which this middle sub-floor 4 is installed in the formwork 1, or the distance of the middle sub-floor 4 from the upper edge 8.

Weiters weist die Schalung 1 Schalungsabschnitte 5 zum Abschalen von Podestbereichen auf, die jeweils einen flachen Unterboden 6 und eine dazu parallel angeordnete Gegenschalungswand 7 aufweisen. Ist ein Schalungsabschnitt 5 zum Abschalen eines oberen Podestbereiches der Fertigtreppe vorgesehen, so erstreckt sich der flache Unterboden 6 vom mittleren Unterboden 4 nach oben. Bei dem in Fig. 1 im Mittelbereich der Schalung 1 dargestellten Schalungsabschnitt 5 ragt der flache Unterboden 6 über die Schalungswände 2 hinaus, wobei die Gegenschalungswand 7 an die Oberkanten 8 der Schalungswände 2 anschließt und von diesen weg schräg nach oben verläuft. Ist der Schalungsabschnitt 5 zum Abschalen eines unteren Podestbereiches der Fertigtreppe vorgesehen, so erstreckt sich der flache Unterboden 6 vom mittleren Unterbodens 4 weg nach unten, wobei die Gegenschalungswand 7 schräg nach unten verläuft und zumindest teilweise, vorzugsweise jedoch gänzlich, zwischen den Schalungswänden 2 angeordnet ist.Furthermore, the formwork 1 has formwork sections 5 for shuttering of platform areas, each of which has a flat sub-floor 6 and a counter-formwork wall 7 arranged parallel thereto. If a shuttering section 5 is provided for shuttering an upper landing area of the finished staircase, the flat sub-floor 6 extends upwards from the middle sub-floor 4 . At the in 1 In the central area of the formwork 1, the formwork section 5 shown protrudes beyond the formwork walls 2, with the counter formwork wall 7 adjoining the upper edges 8 of the formwork walls 2 and extending obliquely upwards away from them. If the shuttering section 5 is provided for shuttering a lower landing area of the finished staircase, the flat sub-floor 6 extends downwards away from the middle sub-floor 4, with the counter-housing wall 7 running diagonally downwards and being arranged at least partially, but preferably entirely, between the shuttering walls 2 .

In der dargestellten Ausführungsform weist die Schalung 1 an ihren beiden Enden jeweils zusätzliche Schalungswandabschnitte 9 und 10 für in Längsrichtung nicht verschiebbare Schalungsabschnitte 5 auf. Die zusätzlichen Schalungswandabschnitte 9 sind mit den Schalungswänden 2 fest verbunden und ragen über die Oberkanten 8 hinaus. Die zusätzlichen Schalungswandabschnitte 10 sind ebenfalls mit den Schalungswänden 2 fest verbunden und ragen unterhalb der Oberkanten 8 nach unten. Zwischen diesen zusätzlichen Schalungswandabschnitten 9 und 10 der nicht verschiebbaren Schalungsabschnitten 5 sind zwei in Längsrichtung der Schalung 1 verschiebbare Schalungsabschnitte 5 angeordnet, sodass mit der dargestellten Schalung 1 bei Bedarf auch zwei Fertigtreppen unterschiedlicher Länge und Form hergestellt werden können.In the illustrated embodiment, the formwork 1 has additional formwork wall sections 9 and 10 for formwork sections 5 that cannot be displaced in the longitudinal direction at both of its ends. The additional formwork wall sections 9 are firmly connected to the formwork walls 2 and protrude beyond the upper edges 8 . The additional formwork wall sections 10 are also firmly connected to the formwork walls 2 and protrude below the upper edges 8 downwards. Arranged between these additional formwork wall sections 9 and 10 of the non-displaceable formwork sections 5 are two formwork sections 5 that can be displaced in the longitudinal direction of the formwork 1, so that with the formwork 1 shown, two prefabricated stairs of different lengths and shapes can also be produced if required.

Ausführungsformen der erfindungsgemäßen Schalung 1 mit mehr als zwei mobilen Schalungsabschnitten 5, mit denen mehr als zwei Fertigtreppen gleichzeitig hergestellt werden können und/oder mit keinem oder nur einem nicht verschiebbaren Schalungsabschnitt 5 sind im Rahmen der Erfindung möglich, ebenso wie Ausführungsformen, bei denen keine zusätzlichen Schalungswandabschnitte 9, 10 vorgesehen sind.Embodiments of the formwork 1 according to the invention with more than two mobile formwork sections 5, with which more than two prefabricated stairs can be produced simultaneously and/or with no or only one non-movable formwork section 5 are possible within the scope of the invention, as are embodiments in which no additional Formwork wall sections 9, 10 are provided.

Im Rahmen der Erfindung sind auch Ausführungsformen der erfindungsgemäßen Schalung 1 möglich, bei denen über dem mittleren Unterboden 4, d.h. zwischen den angrenzenden Schalungsabschnitten 5, eine weitere, in den Figuren nicht dargestellte, im Wesentlichen waagerechte Gegenschalungswand angeordnet ist. Diese weitere Gegenschalungswand kann beispielsweise auf den Oberkanten 8 der Seitenwände 2 aufliegen und gegen Abheben fixiert sein.Within the scope of the invention, embodiments of the formwork 1 according to the invention are also possible in which a further, essentially horizontal counter formwork wall (not shown in the figures) is arranged above the middle sub-floor 4, i.e. between the adjacent formwork sections 5. This additional counter formwork wall can rest, for example, on the upper edges 8 of the side walls 2 and be fixed against lifting.

Zwischen zwei Schalungsabschnitten 5 und zwischen den Seitenwänden 2 kann eine im Wesentlichen zu den Seitenwänden 2 parallele, seitliche Abschalung 17 angeordnet sein. Durch Positionieren und Fixieren der Abschalung 17 zwischen den Seitenwänden 2, kann die Breite eines durch die Abschalung 17 zur Seite hin begrenzten Schalungsbereiches variiert werden, sodass unterschiedlich breite Fertigtreppen durch Befüllen des begrenzten Schalungsbereiches fertigbar sind. Die seitliche Abschalung 17 weist eine nach oben gerichtete obere Kante 20 und eine nach unten gerichtete untere Kante 21 auf. Die obere Kante 20 der seitlichen Abschalung 17 verläuft im Bereich des mittleren Unterbodens 4 im Wesentlichen waagerecht und in Bereichen von flachen Unterböden 6 im Wesentlichen parallel zu diesen, sodass vorzugsweise eine oder beide der Gegenschalungswände 7 der Schalungsabschnitte 5 und gegebenenfalls eine weitere, zwischen den Schalungsabschnitten 5 angeordnete Gegenschalungswand auf der oberen Kante 20 der Abschalung 17 aufliegt/en. Die untere Kante 21 der Abschalung 17 ist analog zum mittleren Unterboden 4 und zu den gegebenenfalls daran anschließenden flachen Unterböden 6 geformt, sodass die Abschalung 17 mit der unteren Kante 21 dicht an den Unterböden 4, 6 anliegt.Between two formwork sections 5 and between the side walls 2 , a side formwork 17 that is essentially parallel to the side walls 2 can be arranged. By positioning and fixing the formwork 17 between the Side walls 2, the width of a formwork area limited to the side by the formwork 17 can be varied, so that finished stairs of different widths can be produced by filling the limited formwork area. The side shuttering 17 has an upper edge 20 directed upwards and a lower edge 21 directed downwards. The upper edge 20 of the side shuttering 17 runs essentially horizontally in the area of the central sub-floor 4 and essentially parallel to it in areas of flat sub-floors 6, so that preferably one or both of the opposing formwork walls 7 of the formwork sections 5 and possibly another one between the formwork sections 5 arranged opposite shuttering wall rests on the upper edge 20 of the formwork 17 / s. The lower edge 21 of the shuttering 17 is shaped analogously to the middle sub-floor 4 and to the flat sub-floors 6 that may be adjoining it, so that the lower edge 21 of the shuttering 17 rests tightly against the sub-floors 4 , 6 .

Fig. 2 zeigt ein in einem Detail A von Fig. 1 dargestelltes Gelenk 11 der erfindungsgemäßen Schalung 1 in einer Schnittansicht, die lotrecht entlang einer Schwenkachse 12 des Gelenkes 11 verläuft. Das Gelenk 11 ist in dieser Figur im nicht verschwenkten Zustand dargestellt, wobei der die Gegenschalung 7 mit dem Gelenk 11 verbindende Schwenkarm 48 horizontal ausgerichtet ist. 2 shows a in a detail A of 1 illustrated joint 11 of the formwork 1 according to the invention in a sectional view, which runs perpendicularly along a pivot axis 12 of the joint 11. The joint 11 is shown in this figure in the non-pivoted state, with the swivel arm 48 connecting the counter formwork 7 to the joint 11 being aligned horizontally.

Das Gelenk 11 weist einen Auflageteil 13 und einen Schwenkteil 14 auf, wobei der Schwenkteil 14 um die Schwenkachse 12 gegenüber dem Auflageteil 13 verschwenkbar ist.The joint 11 has a bearing part 13 and a pivoting part 14 , the pivoting part 14 being pivotable about the pivot axis 12 with respect to the bearing part 13 .

Der Auflageteil 13 weist eine Stützplatte 15 auf, an der eine Auflageplatte 16 angeordnet, insbesondere angeschweißt, ist. Die Auflageplatte 16 ist zur Stützplatte 15 im rechten Winkel angeordnet.The support part 13 has a support plate 15 on which a support plate 16 is arranged, in particular welded. The support plate 16 is arranged to the support plate 15 at right angles.

Die Schalungswand 2 der erfindungsgemäßen Schalung 1 weist ein Rahmenprofil 18 auf, das an einer im Wesentlichen lotrechten Schalungswandplatte 19 angeordnet, insbesondere an diese angeschweißt, ist. Die Oberkante 8 der Schalungswand 2 bzw. der Schalungswandplatte 19 ist, vorzugsweise nur geringfügig, höher als das Rahmenprofil 18.The formwork wall 2 of the formwork 1 according to the invention has a frame profile 18 which is arranged on a substantially vertical formwork wall panel 19, in particular welded to it. The upper edge 8 of the formwork wall 2 or the formwork wall panel 19 is, preferably only slightly, higher than the frame profile 18.

Das Rahmenprofil 18 ist als Hohlprofil mit einem im wesentlichen rechteckigen Querschnitt ausgeführt, kann jedoch auch massiv ausgeführt sein und/oder einen anderen Querschnitt aufweisen, beispielsweise plattenförmig sein.The frame profile 18 is designed as a hollow profile with an essentially rectangular cross section, but it can also be made solid and/or have a different cross section, for example it can be plate-shaped.

Auf einer Oberseite 23 des Rahmenprofils 18 ist ein Zwischenteil angeordnet, der in der dargestellten Ausführungsform als Zwischenleiste 24 ausgeführt ist. Die Zwischenleiste 24 ist vorzugsweise schmäler als das Rahmenprofil 18, sodass das Rahmenprofil 18 zur Seite hin, von der Schalungswandplatte 19 weg, über die Zwischenleiste 24 vorragt.An intermediate part is arranged on an upper side 23 of the frame profile 18 and is designed as an intermediate strip 24 in the illustrated embodiment. The intermediate strip 24 is preferably narrower than the frame profile 18 so that the frame profile 18 projects to the side, away from the formwork panel 19, over the intermediate strip 24.

Das Gelenk 11 ist mit der Auflageplatte 16 des Auflageteiles 13 über der Zwischenleiste 24 angeordnet. Die Auflageplatte 16 kann direkt auf der Zwischenleiste 24 aufliegen, es kann zwischen der Auflageplatte 16 und der Zwischenleiste 24 aber auch ein schmaler Spalt bestehen, wie in Fig. 2 dargestellt ist.The joint 11 is arranged with the support plate 16 of the support part 13 above the intermediate strip 24 . The support plate 16 can rest directly on the intermediate strip 24, but there can also be a narrow gap between the support plate 16 and the intermediate strip 24, as in 2 is shown.

Innerhalb des durch die Platten 15, 16 gebildeten, zum Rahmenprofil 18 hin gerichteten rechten Winkels sind mehrere, vorzugsweise zwei, Auflagerippen 25 orthogonal zur Auflageplatte 16 und zur Stützplatte 15 angeordnet. Die Auflagerippen 25 verlaufen von der Stützplatte 15 etwa bis zur Zwischenleiste 24 und liegen mit einer unteren Kante auf der Oberseite 23 des Rahmenprofils 18 auf.Within the right angle formed by the plates 15, 16 and directed towards the frame profile 18, several, preferably two, bearing ribs 25 are arranged orthogonally to the bearing plate 16 and to the support plate 15. The support ribs 25 run from the support plate 15 approximately to the intermediate strip 24 and rest with a lower edge on the upper side 23 of the frame profile 18 .

An einer den Auflagerippen 25 gegenüberliegenden Seite der Auflageplatte 16 sind in dem durch die Platten 15, 16 gebildeten Winkel mehrere, vorzugsweise zwei, Stützrippen 26 orthogonal zur Auflageplatte 16 und zur Stützplatte 15, angeordnet.On a side of the support plate 16 opposite the support ribs 25 are formed by the plates 15,16 Angle several, preferably two, support ribs 26 orthogonal to the support plate 16 and the support plate 15, respectively.

Das Rahmenprofil 18 weist in Längserstreckung entlang der Oberkante 8 mehrere erste Mittel zum Festlegen des Gelenkes 11 auf, die in der dargestellten Ausführungsform erste Ausnehmungen 27, insbesondere Bohrungen, sind.In the longitudinal extension along the upper edge 8, the frame profile 18 has a plurality of first means for fixing the joint 11, which in the illustrated embodiment are first recesses 27, in particular bores.

Die Zwischenleiste 24 weist dritte und vierte Mittel zum Festlegen auf, die in der dargestellten Ausführungsform weitere Ausnehmungen 28, 29, vorzugsweise Bohrungen, sind.The intermediate strip 24 has third and fourth means for fixing, which in the illustrated embodiment are further recesses 28, 29, preferably bores.

Die Auflageplatte 16 weist ein zweites Mittel zum Festlegen auf, welches in der dargestellten Ausführungsform eine zweite Ausnehmung 31, vorzugsweise eine Bohrung, ist und durch die Auflageplatte 16 hindurch führt.The support plate 16 has a second means for fixing, which in the illustrated embodiment is a second recess 31, preferably a bore, and extends through the support plate 16.

Ein erstes Verbindungselement 32, das vorzugsweise als Bolzen oder Stift ausgeführt ist, verbindet das erste und das dritte Mittel, indem es durch die erste Ausnehmung 28 in der Zwischenleiste 24 und durch die weitere Ausnehmung 27 im Rahmenprofil 18 geführt bzw. gesteckt ist, sodass die Zwischenleiste 24 entlang des Rahmenprofils 18 an einer bestimmten Position fixiert bzw. festgelegt ist.A first connecting element 32, which is preferably designed as a bolt or pin, connects the first and third means by being guided or inserted through the first recess 28 in the intermediate strip 24 and through the further recess 27 in the frame profile 18, so that the Is intermediate bar 24 fixed or fixed along the frame profile 18 at a certain position.

Ein zweites Verbindungselement 33, das wie das erste Verbindungselement 32 als Bolzen oder Stift, vorzugsweise mit einem anderen Durchmesser, ausgeführt ist, verbindet das zweite und das vierte Mittel, indem es durch die weitere Ausnehmung 29 in der Zwischenleiste 24 und durch die zweite Ausnehmung 31 in der Auflageplatte 16 des Auflageteiles 13 geführt bzw. gesteckt ist, sodass der Auflageteil 13 und somit das Gelenk 11 an einer bestimmten Position der Zwischenleiste 24 fixiert bzw. festgelegt ist.A second connecting element 33, which like the first connecting element 32 is designed as a bolt or pin, preferably with a different diameter, connects the second and the fourth means by passing through the further recess 29 in the intermediate strip 24 and through the second recess 31 is guided or inserted in the support plate 16 of the support part 13, so that the support part 13 and thus the joint 11 is fixed or fixed at a specific position of the intermediate strip 24.

Möglich sind auch Ausführungsformen, bei denen die Verbindungselemente 32, 33 nicht eingesteckt, sondern eingeschraubt sind, oder bei denen die Verbindungselemente 32, 33 und die Ausnehmungen 27, 28, 29, 31 keine kreisrunde, sondern eine davon abweichende, beispielsweise eine rechteckige, Form aufweisen.Embodiments are also possible in which the connecting elements 32, 33 are not inserted but screwed in, or in which the connecting elements 32, 33 and the recesses 27, 28, 29, 31 are not circular but have a different shape, for example a rectangular shape exhibit.

Insbesondere sind aber auch Ausführungsformen möglich, bei denen auf ein oder beide Verbindungselemente 32, 33 verzichtet wird, indem beispielsweise anstelle der Ausnehmung 28 in der Zwischenleiste 24 und der Ausnehmung 31 in der Auflageplatte 16 Zapfen oder dergleichen angebracht sind, welche in die jeweils zugehörige Ausnehmung 27 im Rahmenprofil 18 und die Ausnehmung 29 in der Zwischenleiste 24 eingesteckt werden. Genauso ist dies auch umgekehrt möglich. Der Vorteil dieser Ausführungsform mit Zapfen oder dergleichen ist, dass keine Verbindungselemente 32, 33 benötigt werden, die verloren gehen oder verklemmen können. Natürlich kann auch nur eine der beiden Ausnehmungen 28, 29 durch einen Zapfen oder dergleichen ersetzt werden.In particular, however, embodiments are also possible in which one or both connecting elements 32, 33 are omitted, for example, instead of the recess 28 in the intermediate strip 24 and the recess 31 in the support plate 16, pins or the like are attached, which fit into the respective associated recess 27 are inserted in the frame profile 18 and the recess 29 in the intermediate strip 24. The reverse is also possible. The advantage of this embodiment with pins or the like is that no connecting elements 32, 33 are required, which can get lost or jammed. Of course, only one of the two recesses 28, 29 can be replaced by a pin or the like.

Weiters sind Ausführungsformen möglich, bei denen zusätzliche weitere Ausnehmungen 28, 29, in der Zwischenleiste 24 und/oder zusätzliche Ausnehmungen 31 in der Auflageplatte 16 vorgesehen sind, sodass die Zwischenleiste 24 an dem Rahmenprofil 18 und/oder der Auflageteil 13 an der Zwischenleiste 24 durch weitere Verbindungselemente 32, 33 stärker fixierbar ist.Furthermore, embodiments are possible in which additional further recesses 28, 29 are provided in the intermediate strip 24 and/or additional recesses 31 in the support plate 16, so that the intermediate strip 24 on the frame profile 18 and/or the support part 13 on the intermediate strip 24 further connecting elements 32, 33 can be fixed more strongly.

Möglich sind auch in den Zeichnungen nicht dargestellte Ausführungsformen der erfindungsgemäßen Schalung ohne Zwischenleiste 24, wie beispielsweise eine Ausführungsform, bei der keine Auflagerippen 25 vorhanden sind und das Gelenk 11 mit der Auflageplatte 16 direkt auf dem Rahmenprofil 18 aufliegt.Also possible are embodiments of the formwork according to the invention, not shown in the drawings, without an intermediate strip 24, such as an embodiment in which there are no support ribs 25 and the joint 11 with the support plate 16 rests directly on the frame profile 18.

Die Stützplatte 15 des Auflageteiles 13 liegt seitlich an einer von der Schalungswand 2 abgewandten Seitenfläche 34 des Rahmenprofiles 18 an. Ein zylinderförmiger Zapfen 35 ist fest an der Stützplatte 15 angeordnet, insbesondere an dieser angeschweißt, und ragt orthogonal von einer von der Schalungswand 2 abgewandten Seitenfläche 36 der Stützplatte 15 ab.The support plate 15 of the support part 13 lies laterally against a side face 34 of the frame profile 18 facing away from the formwork wall 2 . A cylindrical pin 35 is fixed arranged on the support plate 15, in particular welded to it, and protrudes orthogonally from a side surface 36 of the support plate 15 facing away from the formwork wall 2.
