Definitions
- the invention relates to a formwork element for formwork of an inner corner, for example the inner corner at a crossing point of two beams of a ceiling, the formwork element having two formwork skins that are at the same height and at the same height and have a common end, facing away from them, fastening points for attachable to them Formwork panels or the like are provided.
- Such a formwork element is known for example from DE-A-2 119 362.
- This known formwork element is designed as a formwork corner and has two hollow legs which have on their outside the formlining for the inside corner and on their end faces the fastening elements for formwork panels to be connected.
- Such a formwork corner is well suited for formworking two concrete surfaces at an angle to each other.
- these known formwork corners can be increased and have dowel pins or the like at their upper end.
- this formwork element is not suitable for spatial inner corners, such as those encountered at intersection points between two beams of a ceiling or in a room corner when they meet two walls and the ceiling occur without additional formwork.
- a custom-made formwork panel is usually required, which closes a corresponding gap or opening of the formwork panels that meet for the vertical concrete surfaces. Nevertheless, the vertical formwork panels, which form a corner, have to be pressure-tightly connected to each other in order to absorb the concrete pressure.
- the object of the invention is to improve a formwork element of the type mentioned at the outset in such a way that it can formwork a spatial internal corner without custom-made and fitting additional formwork parts while still being easily connectable Formwork elements arranged in a corner are permitted.
- All three formwork skins are preferably arranged approximately at right angles to one another.
- a preferred embodiment can consist in that a further formwork skin is provided at the remote common end of the formwork element transversely to the two formwork skins opposite the fastening points.
- the formwork element can then also be used turned through 180 °.
- walls with elongated holes can be provided as fastening points, preferably with elongated slots extending over the entire length of the formwork element, for connecting narrow sides or end faces of formwork panels and / or corner elements at any height.
- a formwork corner for example according to DE-PS 2 119 362, could be connected in alignment with the transverse third formlining in the upper ceiling area, so that it can then form the inside corner between the ceiling and the long side of a beam.
- formwork panels can then be connected with their edge webs and end faces to form a ceiling at the main surface of a beam or a wall and at right angles to it in connection with the other legs of the formwork ceiling.
- the transverse formwork skin is expediently designed as a rectangular, preferably square end plate and covers the two formwork skins and the walls of the formwork element, which have the fastening slots or the like, in particular flush at their edges. Between the transverse formwork skins and the walls of the formwork element, at least one space that preferably extends over its entire height and over its corner area opposite the inner corner can be open. It can then be reached through in order to be able to grip fastening elements in the interior of the formwork element if their fastening or loosening makes such an intervention necessary.
- formwork corners which only have keyhole-type perforations for push-through bolts with cross pins at their front ends, could be brought into overlap with the slot with such a perforation, after which the corresponding bolt was inserted from the inside of the formwork element through the elongated slot and the keyhole-type perforation of the formwork corner can be.
- Embodiments of the invention are the subject of further claims.
- a formwork element results, which allows the joint formwork of ceilings and joists without having to make complex additional parts and possibly have to be assembled with difficulty.
- the formwork element allows the connection of formwork panels and formwork corners, which in turn then enable the connection of formwork panels in the ceiling area, so that already existing parts can be connected without problems and the spatial inner corner is formed by the formwork element itself
- a formwork element 1 is used according to FIG. 2 to form a spatial inner corner, in this case an inner corner at a crossing point or corner point of two beams 2 of a ceiling, not shown.
- the formwork element 1 has two formwork skins 3 which are at an angle to the inner corner and have a common end at the same height.
- Averting points 4 are provided for connecting formwork panels 5 or the like and formwork corners 6 which continue the formwork skins 3.
- FIG. 1 At the front ends of the two formworks, further formworks 7 extending transversely to them are fastened according to FIG. 1 to form the spatial inner corner.
- a single such formlining 7 is sufficient, but the formwork element according to FIG. 1 can be used with two such additional formlining 7 either in the position shown or in a position turned through 180 °.
- All formwork skins 3 and 7 are each arranged approximately at right angles to one another.
- a flat formwork element 5 and a formwork corner 6 can also be connected to the second fastening point 4, which is left open in FIG. 2 for the better overview, in which case the end faces 6 a of allow two formwork corners 6 oriented at right angles to one another in turn to fit a rectangular formwork panel for a ceiling to be formwork.
- walls 8 are connected to the rear sides of the formwork skins 3 at right angles in cross section with elongated holes as fastening points 4, in the exemplary embodiment continuous slits are provided over the entire length or height of the formwork element 1 for connecting the formwork panels 5 and the corner elements 6.
- these formwork elements 5 and 6 can be provided at any height and thus allow adaptation to different heights of the beams 2. It should be mentioned that formwork panels 5 can then be connected to the formwork panels 5 via angles 9 for the underside of the beams 2. All in all, it can be seen that with the help of the formwork element 1, beams that intersect or are at an angle to one another can be easily formed together with a ceiling using only the formwork parts to be kept in stock. It is also easy to remove the formwork afterwards.
- transverse formlining 7 is designed as a rectangular, in the embodiment square end plate and covers the two formlinings 3 and the walls 8 or the like. In this way, a box-shaped and therefore very stable formwork element 1 is created.
- an intermediate space 11 which extends over the entire height and over the corner region opposite the inner corner, through which the interior of the box-shaped formwork element is accessible.
- fastening bolts or the like can be inserted, for example, through this intermediate space 11 and inserted from the inside through the elongated slot 4 into the end face of a formwork ceiling 6. This space is of great importance for the simplicity of assembly.
- the cross section of the formwork element 1 and thus also the transverse formwork 7 is square.
- the result is a largely symmetrical formwork element which can be inserted into an inner corner in any orientation.
- the formwork 3 and 7 and the connecting walls 8 with the attachment points 4 can be made of sheet steel. It is conceivable in particular for formwork elements of greater height that 1 stiffening webs or plates, in particular at least one stiffening extending over the cross section, are provided in the interior of the box-shaped, partially open formwork element. This is not necessary in the embodiment shown for forming internal corners in joists, but such reinforcements could be advantageous for greater heights, for example for forming spatial internal corners between walls and a ceiling.

Abstract
Description
Die Erfindung betrifft ein Schalungselement zum Schalen einer Innenecke, beispielsweise der Innenecke an einem Kreuzungspunkt zweier Unterzüge einer Decke, wobei das Schalungselement zwei im Winkel der Innenecke zueinander stehende, auf gleicher Höhe ein gemeinsames Ende aufweisende Schalhäute hat, denen abgewandt Befestigungsstellen für daran anschließbare, die Schalhäute fortsetzende Schaltafeln od. dgl. vorgesehen sind.The invention relates to a formwork element for formwork of an inner corner, for example the inner corner at a crossing point of two beams of a ceiling, the formwork element having two formwork skins that are at the same height and at the same height and have a common end, facing away from them, fastening points for attachable to them Formwork panels or the like are provided.
Ein derartiges Schalungselement ist beispielsweise aus der DE-A- 2 119 362 bekannt. Dieses bekannte Schalungselement ist dabei als Schalungsecke ausgebildet und weist zwei hohle Schenkel auf, die an ihrer Außenseite die Schalhäute für die Innenecke und an ihren Stirnseiten die Befestigungselemente für anzuschließende Schaltafeln haben. Eine solche Schalungsecke ist zum Schalen zweier im Winkel zueinander stehender Betonflächen gut geeignet. Für unterschiedliche Höhen der Innenecke können dabei diese bekannten Schalungsecken aufgestockt werden und haben dazu an ihrem oberen Ende Paßstifte od. dgl. Dieses Schalungselement ist jedoch nicht geeignet, räumliche Innenecken, wie sie beispielsweise an Kreuzungspunkten zweier Unterzüge einer Decke oder auch in einer Raumecke beim Aufeinandertreffen zweier Wände und der Decke auftreten, ohne zusätzliche Maßnahmen zu schalen. Für die obere horizontale Schalhaut ist dann in der Regel eine Sonderanfertigung einer Schaltafel erforderlich, die eine entsprechende Lücke oder Öffnung der aufeinandertreffenden Schaltafeln für die vertikalen Betonflächen verschließt. Dennoch müssen die vertikalen, eine Ecke bildenden Schaltafeln ihrerseits miteinander druckfest verbunden werden, um den Betonierdruck aufzufangen.Such a formwork element is known for example from DE-A-2 119 362. This known formwork element is designed as a formwork corner and has two hollow legs which have on their outside the formlining for the inside corner and on their end faces the fastening elements for formwork panels to be connected. Such a formwork corner is well suited for formworking two concrete surfaces at an angle to each other. For different heights of the inner corner, these known formwork corners can be increased and have dowel pins or the like at their upper end. However, this formwork element is not suitable for spatial inner corners, such as those encountered at intersection points between two beams of a ceiling or in a room corner when they meet two walls and the ceiling occur without additional formwork. For the upper horizontal formlining, a custom-made formwork panel is usually required, which closes a corresponding gap or opening of the formwork panels that meet for the vertical concrete surfaces. Nevertheless, the vertical formwork panels, which form a corner, have to be pressure-tightly connected to each other in order to absorb the concrete pressure.
Da vor allem bei Decken mit Unterzügen zahlreiche derartige räumliche Innenecken entstehen, liegt der Erfindung die Aufgabe zugrunde, ein Schalungselement der eingangs erwähnten Art dahingehend zu verbessern, daß es die Schalung einer räumlichen Innenecke ohne Sonderanfertigung und Einpassung von zusätzlichen Schalungsteilen bei dennoch guter Verbindbarkeit der über Eck angeordneten Schalungselemente erlaubt.Since numerous such spatial internal corners arise, especially in ceilings with joists, the object of the invention is to improve a formwork element of the type mentioned at the outset in such a way that it can formwork a spatial internal corner without custom-made and fitting additional formwork parts while still being easily connectable Formwork elements arranged in a corner are permitted.
Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß am gemeinsamen Ende der beiden Schalhäute zur Bildung einer räumlichen Innenecke eine quer zu ihnen verlaufende weitere Schalhaut befestigt ist. Somit ist auch im Deckenbereich von vorneherein ein Übergang zu Nachbarschalelementen gegeben, die bei ihrem Aneinanderstoßen in diesem Bereich eine Lücke freilassen würden, weil sie an denjenigen Schaltafeln angeschlossen werden, die ihrerseits an den Befestigungsstellen des Schalungselementes angreifen.The solution to this problem consists essentially in the fact that at the common end of the two formwork skins to form a spatial inner corner, a further formwork skin extending transversely to them is attached. Thus, even in the ceiling area, there is a transition from the outset to neighboring formwork elements that would leave a gap in this area if they collided because they are connected to those formwork panels that in turn attack the fastening points of the formwork element.
Bevorzugt sind alle drei Schalhäute etwa im rechten Winkel zueinander angeordnet. Eine bevorzugte Ausführungsform kann dabei darin bestehen, daß am entgesetzten gemeinsamen Ende des Schalungselementes quer zu den beiden den Befestigungsstellen gegenüberliegenden Schalhäuten eine weitere Schalhaut vorgesehen ist. Das Schalungselement kann dann auch um 180° gewendet benutzt werden.All three formwork skins are preferably arranged approximately at right angles to one another. A preferred embodiment can consist in that a further formwork skin is provided at the remote common end of the formwork element transversely to the two formwork skins opposite the fastening points. The formwork element can then also be used turned through 180 °.
An den Rückseiten der Schalhäute, vorzugsweise im Querschnitt rechtwinklig dazu, können Wände mit Langlöchern als Befestigungsstellen, vorzugsweise mit über die gesamte Länge des Schalungselementes durchgehender Langschlitzen, zum Anschließen von Schmalseiten oder Stirnseiten von Schaltafeln und/oder Eckelementen in beliebiger Höhe vorgesehen sein. Beispielsweise könnte im oberen Deckenbereich fluchtend mit der quer verlaufenden dritten Schalhaut eine Schalungsecke etwa gemäß der DE-PS 2 119 362 angeschlossen werden, so daß diese dann die Innenecke zwischen der Decke und der Längsseite eines Unterzuges bilden kann. An deren Stirnseiten sowie unterhalb des Anschlusses an dem Schalungselement können dann Schaltafeln mit ihren Randstegen und Stirnseiten angeschlossen werden, um die Hauptfläche eines Unterzuges oder einer Wand und rechtwinklig dazu im Anschluß an den anderen Schenkel der Schalungsdecke eine Decke zu schalen.On the rear sides of the formlining, preferably at right angles in cross section, walls with elongated holes can be provided as fastening points, preferably with elongated slots extending over the entire length of the formwork element, for connecting narrow sides or end faces of formwork panels and / or corner elements at any height. For example, a formwork corner, for example according to DE-PS 2 119 362, could be connected in alignment with the transverse third formlining in the upper ceiling area, so that it can then form the inside corner between the ceiling and the long side of a beam. At their end faces and below the connection to the formwork element, formwork panels can then be connected with their edge webs and end faces to form a ceiling at the main surface of a beam or a wall and at right angles to it in connection with the other legs of the formwork ceiling.
Die quer verlaufende Schalhaut ist zweckmäßigerweise als rechteckige, vorzugsweise quadratische Abschlußplatte ausgebildet und überdeckt die beiden Schalhäute sowie die die Befestigungsschlitze od. dgl. aufweidenden Wände des Schalungselementes an deren Rändern insbesondere bündig. Zwischen den quer verlaufenden Schalhäuten und den Wänden des Schalungselementes kann dabei wenigstens ein vorzugsweise über seine gesamte Höhe und über seinen der Innenecke gegenüberliegenden Eckbereich reichender Zwischenraum offen sein. Durch diesen kann dann hindurchgegriffen werden, um auch im Inneren des Schalungselementes Befestigungselemente fassen zu können falls deren Befestigen oder Lösen einen solchen Eingriff erforderlich macht. Beispielsweise könnten Schalungsecken, die an ihren stirnseitigen Enden lediglich schlüssellochartige Lochungen für Durchsteckbolzen mit Querstiften haben, mit einer solchen Lochung in Überdeckung mit dem Schlitz gebracht werden, wonach der entsprechende Bolzen von der Innenseite des Schalungselementes her durch den Langschlitz und die schlüssellochartige Lochung der Schalungsecke gesteckt werden kann.The transverse formwork skin is expediently designed as a rectangular, preferably square end plate and covers the two formwork skins and the walls of the formwork element, which have the fastening slots or the like, in particular flush at their edges. Between the transverse formwork skins and the walls of the formwork element, at least one space that preferably extends over its entire height and over its corner area opposite the inner corner can be open. It can then be reached through in order to be able to grip fastening elements in the interior of the formwork element if their fastening or loosening makes such an intervention necessary. For example, formwork corners, which only have keyhole-type perforations for push-through bolts with cross pins at their front ends, could be brought into overlap with the slot with such a perforation, after which the corresponding bolt was inserted from the inside of the formwork element through the elongated slot and the keyhole-type perforation of the formwork corner can be.
Ausgestaltungen der Erfindung sind Gegenstand weiterer Ansprüche. Insbesondere bei Kombination einzelner oder mehrerer der vorbeschriebenen sowie der in den weiteren Ansprüchen angegebenen Merkmale und Maßnahmen ergibt sich ein Schalungselement, welches das gemeinsame Schalen von Decken und Unterzügen erlaubt, ohne daß aufwendige Zusatzteile angefertigt und unter Umständen mit Schwierigkeiten montiert werden müssen. Das Schalungselement erlaubt vielmehr das Anschließen von Schaltafeln und Schalungsecken, die ihrerseits dann das Anschließen von Schaltafeln im Deckenbereich ermöglichen, so daß schon vorhandene Teile problemlos verbunden werden können und die räumliche Innenecke durch das Schalungselement selbst gebildet istEmbodiments of the invention are the subject of further claims. In particular when combining one or more of the features and measures described above and in the further claims, a formwork element results, which allows the joint formwork of ceilings and joists without having to make complex additional parts and possibly have to be assembled with difficulty. Rather, the formwork element allows the connection of formwork panels and formwork corners, which in turn then enable the connection of formwork panels in the ceiling area, so that already existing parts can be connected without problems and the spatial inner corner is formed by the formwork element itself
Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben. Es zeigt:
- Fig. 1 in schaubildlicher Darstellung ein erfindungsgemäßes Schalungselement und
- Fig. 2 ein Anwendungsbeispiel des erfindungsgemäßen Schalungselementes beim Schalen eines Unterzuges mit einem Teil der dann an ihm angeschlossenen weiteren Schalungselemente.
- Fig. 1 in a schematic representation of a formwork element according to the invention and
- Fig. 2 shows an application example of the formwork element according to the invention when forming a beam with part of the other formwork elements then connected to it.
Ein Schalungselement 1 dient gemäß Fig. 2 zum Schalen einer räumlichen Innenecke, in diesem Falle einer Innenecke an einem Kreuzungspunkt oder Eckpunkt zweier Unterzüge 2 einer nicht näher dargestellten Decke. Das Schalungselement 1 hat dabei zwei im Winkel der Innenecke zueinander stehende, auf gleicher Höhe ein gemeinsames Ende aufweisende Schalhäute 3. Diesen abgewandt sind jeweils Befestigungsstellen 4 für daran anschließbare, die Schalhäute 3 fortsetzende Schaltafeln 5 od. dgl. und Schalungsecken 6 vorgesehen.A
An den stirnseitigen Enden der beiden Schalhäute sind gemäß Fig. 1 zur Bildung der räumlichen Innenecke quer zu ihnen verlaufende weitere Schalhäute 7 befestigt. Für eine räumliche Innenecke genügt an sich eine einzige derartige Schalhaut 7, jedoch läßt sich das Schalungselement gemäß Fig. 1 mit zwei solchen weiteren Schalhäuten 7 wahlweise in der dargestellten oder in einer um 180° gewendeten Position verwenden. Dabei sind alle Schalhäute 3 und 7 jeweils etwa im rechten Winkel zueinander angeordnet. Man erkennt in Fig. 2 deutlich, daß auch an der zweiten Befestigungsstelle 4, die der besseren Übersicht wegen in Fig. 2 freigelassen ist, in gleicher Weise ein ebenes Schalungselement 5 und eine Schalungsecke 6 angeschlossen werden können, wobei dann die Stirnseiten 6 a der beiden rechtwinklig zueinander orientierten Schalungsecken 6 wiederum das Einpassen einer rechtwinkligen Schaltafel für eine zu schalende Decke erlauben.At the front ends of the two formworks,
Im Ausführungsbeispiel sind jeweils an den Rückseiten der Schalhäute 3 im Querschnitt rechtwinklig dazu Wände 8 angeschlossen mit Langlöchern als Befestigungsstellen 4, im Ausführungsbeispiel über die gesamte Länge oder Höhe des Schalungselementes 1 durchgehende Langschlitze zum Anschließen der Schaltafeln 5 und der Eckelemente 6 vorgesehen. Somit können diese Schalungselemente 5 und 6 in beliebiger Höhe vorgesehen sein und erlauben so eine Anpassung an unterschiedliche Höhen der Unterzüge 2. Es sei erwähnt, daß an dem Schalungselement 5 dann wiederum über Winkel 9 Schaltafeln 10 für die Unterseite der Unterzüge 2 angeschlossen werden können. Insgesamt zeigt sich, daß mit Hilfe des Schalungselementes 1 sich kreuzende oder im Winkel zueinander stehende Unterzüge problemlos gemeinsam mit einer Decke lediglich unter Verwendung von auf Lager zu haltenden Schalungsteilen geschalt werden können. Ebenfalls einfach ist anschließend auch wieder das Ausschalen.In the exemplary embodiment,
Vor allem in Fig. 1 erkennt man, daß die quer verlaufende Schalhaut 7 als rechteckige, im Ausführungsbeispiel quadratische Abschlußplatte ausgebildet ist und die beiden Schalhäute 3 sowie die die Befestigungsschlitze 4 od. dgl. aufweisenden Wände 8 an deren Rändern bündig überdeckt. Auf diese Weise entsteht also ein kastenförmiges und somit sehr stabiles Schalungselement 1.Especially in Fig. 1 it can be seen that the
Zwischen den quer verlaufenden Schalhäuten 7 und den Wänden 8 des Schalungselementes 1 erkennt man einen über die gesamte Höhe und über den der Innenecke gegenüberliegenden Eckbereich reichenden Zwischenraum 11, durch welchen das Innere des kastenförmigen Schalungselementes zugänglich wird. Somit können Befestigungsbolzen od. dgl. beispielsweise durch diesen Zwischenraum 11 eingeführt und von der Innenseite durch den Langschlitz 4 in die Stirnseite einer Schalungsdecke 6 eingeführt werden. Für die Einfachheit der Montage kommt deshalb diesem Zwischenraum eine große Bedeutung zu.Between the
Im Ausführungsbeispiel ist der Querschnitt des Schalungselementes 1 und somit auch die quer verlaufende Schalhäute 7 quadratisch. Es ergibt sich so ein weitgehend symmetrisches Schalungselement, welches in beliebiger Orientierung in eine Innenecke eingefügt sein kann.In the exemplary embodiment, the cross section of the
Die Schalhäute 3 und 7 und die Verbindungswände 8 mit den Befestigungsstellen 4 können aus Stahlblech bestehen. Dabei ist es insbesondere für Schalungselemente größerer Höhe denkbar, daß im Inneren des kastenförmigen, teilweise offenen Schalungselementes 1 Aussteifungsstege oder -platten, insbesondere wenigstens eine über den Querschnitt reichende Aussteifung vorgesehen ist. Bei der dargestellten Ausführungsform zum Schalen von Innenecken bei Unterzügen ist dies nicht erforderlich, jedoch könnte für größere Höhen beispielsweise zum Schalen von räumlichen Innenecken zwischen Wänden und einer Decke solche Aussteifungen vorteilhaft sein.The
Alle in der Beschreibung, den Ansprüchen, der Zusammenfassung und der Zeichnung dargestellten Merkmale und Konstruktionsdetails können sowohl einzeln als auch in beliebiger Kombination miteinander wesentliche Bedeutung haben.All features and construction details shown in the description, the claims, the summary and the drawing can have significant meaning both individually and in any combination with one another.
