Definitions

  • the present invention relates to a formwork system for concrete construction.
  • Concrete structures such as floor / ceiling slabs are often concreted in several sections. Reasons for this are, for example, mixing new concrete or taking a break between pouring the individual sections. This creates construction joints that have to be sealed against moisture.
  • the shuttering elements used for this purpose are usually made of steel and have larger dimensions, which leads to a high weight and corresponding difficulties when used on the construction site.

  • a lost formwork is known in which two formwork parts are firmly connected to one another with the aid of a connecting device, leaving a gap free.

If the surfaces mentioned are now all equipped with a sealing coating, in particular with a sealing coating applied over the entire surface, which always has a certain stickiness, then the fitting element is fixed to the standard element and fixed to the angle element, optionally the T-element, after the corresponding surfaces have been brought into contact or the cross element, connected, namely firmly glued together.

  • a further preferred type of application of the coating to the sheet metal strip can therefore be spraying the liquid coating material can be used on the sheet metal strips.

Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft ein Schalungssystem für den Betonbau.The present invention relates to a formwork system for concrete construction.

Stand der TechnikState of the art

Betonkonstruktionen wie beispielsweise Boden-/Deckenplatten werden häufig in mehreren Abschnitten betoniert. Gründe hierfür sind zum Beispiel das Mischen neuen Betons oder eine Arbeitspause zwischen dem Vergießen der einzelnen Abschnitte. Dadurch entstehen Arbeitsfugen, die gegen Feuchtigkeit abgedichtet werden müssen. Die dazu verwendeten Abschalelemente sind üblicherweise aus Stahl gefertigt und weisen größere Abmessungen auf, was zu einem hohen Gewicht und zu entsprechenden Schwierigkeiten beim Einsatz auf der Baustelle führt.Concrete structures such as floor / ceiling slabs are often concreted in several sections. Reasons for this are, for example, mixing new concrete or taking a break between pouring the individual sections. This creates construction joints that have to be sealed against moisture. The shuttering elements used for this purpose are usually made of steel and have larger dimensions, which leads to a high weight and corresponding difficulties when used on the construction site.

Die DE 10 2007 051490 A1 beschreibt ein Schalungssystem für den Betonbau mit zumindest einem Standardelement und zumindest einem Winkelelement.the DE 10 2007 051490 A1 describes a formwork system for concrete construction with at least one standard element and at least one angle element.

Aus der EP 0 513 740 B1 ist eine verlorene Schalung bestehend aus Schalungsteilen, die aus miteinander verbundenen Quer- und Längsstäben und einer dazwischen liegenden Metalltafel aufgebaut sind, und einer mit den Schalungsteilen fest verbundenen flächigen Wassersperre aus Blechmaterial bekannt.From the EP 0 513 740 B1 a permanent formwork consisting of formwork parts, which are made up of interconnected transverse and longitudinal bars and an intermediate metal panel, and a flat water stop made of sheet metal material firmly connected to the formwork parts is known.

Aus der DE 20 2008 003 246 U1 ist eine verlorene Schalung bekannt, bei der zwei Schalungsteile unter Freilassung eines Spaltes mit Hilfe einer Verbindungseinrichtung fest miteinander verbunden sind. Der Spalt zwischen den beiden Schalungsteilen ist für die Aufnahme einer flächigen Wassersperre vorgesehen.From the DE 20 2008 003 246 U1 a lost formwork is known in which two formwork parts are firmly connected to one another with the aid of a connecting device, leaving a gap free. The gap between the two formwork parts is intended to accommodate a flat water stop.

Die DE 20 2009 005 173 U1 beschreibt ebenfalls eine verlorene Schalung für den Betonbau mit zwei Schalungsteilen und einem als flächige Wassersperre ausgebildeten Blechmaterialstreifen. Die beiden Schalungsteile sind fluchtend in einer Ebene liegend zueinander ausgerichtet, wobei der Blechmaterialstreifen zwischen den beiden Schalungsteilen und senkrecht zur Ebene der Schalungsteile angeordnet ist. Der Blechmaterialstreifen ragt beidseitig über die Ebene der Schalungsteile hinaus. Der Blechmaterialstreifen weist an seinen beiden Oberflächen Befestigungselemente zur Befestigung der Schalungsteile auf, wobei die Schalungsteile in den Befestigungselementen kraftschlüssig klemmend mit dem Blechmaterialstreifen verbunden sind.the DE 20 2009 005 173 U1 also describes a permanent formwork for concrete construction with two formwork parts and a sheet metal strip designed as a flat water barrier. The two formwork parts are aligned with one another lying in one plane, the sheet metal strip being arranged between the two formwork parts and perpendicular to the plane of the formwork parts. The sheet metal strip protrudes on both sides over the level of the formwork parts. The sheet metal strip has fastening elements on both of its surfaces for fastening the formwork parts, the formwork parts in the Fastening elements are non-positively clamped connected to the sheet metal strip.

Häufig verlaufen Fugen nicht über ihre gesamte Ausdehnung hinweg linear, sondern weisen einen abknickenden und sich nachfolgend in abweichender Richtung erstreckenden Verlauf auf. Das Abschalen des Bereichs, in dem die Fuge in horizontaler Richtung einen nicht-linearen Verlauf aufweist und die Abdichtung dieses Bereichs gegen Wasser erfolgt derzeit entweder durch Schalungsteile, die als Sonderanfertigungen spezifisch an die Einbausitutation angepasst hergestellt werden, oder durch Schalungen, die unter hohem Arbeitsaufwand mit Hilfe von an der Baustelle improvisiert zusammengesetzten und aneinander befestigten Schalungsteilen aufgebaut werden. Beide Alternativen sind mit erhöhten Kosten verbunden, welche im ersten Fall durch den erhöhten Aufwand bei der Herstellung der Schalungsteile und im zweiten Fall durch den erhöhten Arbeitsaufwand beim Einbau auf der Baustelle bedingt sind.Joints often do not run linearly over their entire extent, but rather show a kinking course that subsequently extends in a different direction. The shuttering of the area in which the joint has a non-linear course in the horizontal direction and the sealing of this area against water is currently done either by formwork parts that are custom-made specifically for the installation situation, or by formwork that requires a lot of work be assembled with the help of improvised formwork parts that are assembled on the construction site and fastened to one another. Both alternatives are associated with increased costs, which are caused in the first case by the increased effort in the production of the formwork parts and in the second case by the increased workload during installation on the construction site.

Es besteht daher ein Bedarf an einem Schalungssystem, durch das gewinkelt verlaufende Fugen in Boden-/Deckenplatten in einfacher Weise und kostengünstig verschalt und mit einer Abdichtung gegen Wasser ausgestattet werden können.There is therefore a need for a shuttering system by means of which angled joints in floor / ceiling panels can be shuttered in a simple and inexpensive manner and equipped with a water seal.

Das zumindest eine Passelement weist ein Schalungsteil und einen als flächige Wassersperre ausgebildeten, horizontalen Blechmaterialstreifen auf, wobei der horizontale Blechmaterialstreifen im wesentlichen senkrecht zu der Ebene des Schalungsteils ausgerichtet ist und dabei eine erste Oberfläche des horizontalen Blechmaterialstreifens dem Schalungsteil zugewandt und eine zweite Oberfläche des horizontalen Blechmaterialstreifens dem Schalungsteil abgewandt ist und der horizontale Blechmaterialstreifen beidseitig über die Ebene des Schalungsteils hinausragt. Das Schalungsteil ist fest mit der ersten Oberfläche des horizontalen Blechmaterialstreifens verbunden, wobei der horizontale Blechmaterialstreifen und das Schalungsteil in horizontaler Richtung in der Ebene des Schalungsteils die gleiche Ausdehnung PA aufweisen, wobei die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung WA1 des frei zugänglichen Bereichs der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts des Winkelelements in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils entspricht.The at least one fitting element has a formwork part and a horizontal sheet-metal material strip designed as a flat water barrier, the horizontal sheet-metal material strip being oriented essentially perpendicular to the plane of the formwork part, with a first surface of the horizontal sheet-metal material strip facing the formwork part and a second surface of the horizontal sheet-metal material strip facing away from the formwork part and the horizontal sheet metal strip protrudes on both sides over the plane of the formwork part.

Das erfindungsgemäße Schalungssystem für den Betonbau umfasst also zumindest ein Standardelement, zumindest ein Winkelelement und zumindest ein Passelement. Alle drei Elemente weisen einen als Wassersperre ausgebildeten, im eingebauten Zustand in horizontaler Richtung verlaufenden Blechmaterialstreifen auf. Der Blechmaterialstreifen des Standardelements und des Winkelelements ist in einem endständigen Randbereich jeweils frei zugänglich, also nicht mit einem Schalungsteil verbunden. Wie nachfolgend noch im Detail beschrieben wird, werden Bildung einer Abschalung Standardelement und Winkelelement so aufgestellt, dass die beiden frei zugänglichen Abschnitte der Blechmaterialstreifen miteinander fluchtend benachbart zueinander angeordnet sind. Da die Ausdehnung des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils der Summe aus Ausdehnung des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung des frei zugänglichen Bereichs der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts des Winkelelements in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils entspricht, kann das Passelement zwischen Standardelement und Winkelelement eingeschoben werden. Die Schalungsteile der drei Elemente sind dann in einer gemeinsamen Ebene angeordnet und bilden eine durchgängige, geschlossene Schalung.The formwork system according to the invention for concrete construction thus comprises at least one standard element, at least one angle element and at least one fitting element. All three elements have a strip of sheet metal material which is designed as a water barrier and runs in the horizontal direction when installed. The sheet metal strip the standard element and the angle element are each freely accessible in a terminal edge area, that is, not connected to a formwork part. As will be described in more detail below, the standard element and the angle element are set up to form a shuttering such that the two freely accessible sections of the sheet metal material strips are arranged adjacent to one another in alignment with one another. Since the expansion of the horizontal sheet metal strip of the fitting element in the horizontal direction in the plane of the formwork part is the sum of the expansion of the freely accessible area of the first surface of the horizontal sheet metal strip of the standard element in the horizontal direction in the plane of the upper formwork part plus the expansion of the freely accessible area of the first surface of the first sheet metal strip section of the angle element corresponds in the horizontal direction in the plane of the first upper formwork part, the fitting element can be inserted between the standard element and the angle element. The formwork parts of the three elements are then arranged in a common plane and form a continuous, closed formwork.

Die drei Schalungselemente Standardelement, Winkelelement und Passelement stellen somit ein Baukastensystem zur Verfügung, mit dessen Hilfe eine große Vielfalt an nichtlinear verlaufenden Fugen abgeschalt werden können. Es ist keine an die jeweilige Einbausituation angepasste Konfektionierung erforderlich. Da die Elemente in großer Stückzahl vorgefertigt werden, ergeben sich deutliche Kosteneinsparungen im Vergleich zu individuell gefertigten Schalungen.The three formwork elements standard element, angle element and fitting element thus provide a modular system with the help of which a large variety of non-linear joints can be shut off. No assembly adapted to the respective installation situation is required. Since the elements are prefabricated in large numbers, there are significant cost savings compared to individually manufactured formwork.

Dem Fachmann ist bekannt, dass die auf den beiden Seiten einer Wassersperre angeordneten Schalungsteile eines Schalungselements üblicherweise in einer gemeinsamen Ebene angeordnet sind. Ein Versatz der auf verschiedenen Seiten beispielsweise eines Fugenblechs angeordneten Schalungsteile relativ zueinander bringt keinerlei technischen Vorteile, es müsste aber die Wassersperre entsprechend breiter dimensioniert werden, damit diese um das benötigte Maß beidseitige über die Schalungsteile hinausragt. Wenn also im Rahmen des vorliegenden Textes in der allgemeinen Beschreibung und bei den Ausführungsbeispielen darauf hingewiesen wird, dass ein beliebiges unteres Schalungsteil und ein beliebiges oberes Schalungsteil in einer gemeinsamen Ebene angeordnet sind, so ist dies den genannten technischen Notwendigkeiten geschuldet. Ein unwesentlicher Versatz der Schalungsteile eines Schalungselements relativ zueinander ist selbstverständlich von der vorliegenden Erfindung umfasst.It is known to the person skilled in the art that the shuttering parts of a shuttering element arranged on the two sides of a water barrier are usually arranged in a common plane. An offset of the shuttering parts arranged on different sides, for example of a metal seam, relative to one another does not bring any technical advantages, but the water stop would have to be dimensioned wider so that it protrudes over the shuttering parts on both sides by the required amount. If it is pointed out in the context of the present text in the general description and in the exemplary embodiments that any lower formwork part and any upper formwork part are arranged in a common plane, this is due to the technical requirements mentioned. An insignificant offset of the formwork parts of a formwork element relative to one another is of course covered by the present invention.

Die Flexibilität des erfindungsgemäßen Schalungssystems kann weiter erhöht werden, wenn gemäß einer bevorzugten Ausführungsform das Winkelelment als T-Element ausgebildet ist oder den drei Schalungselementen Standardelement, Winkelelement und Passelement ein T-Element hinzugefügt wird. Ein T-Element weist ein erstes unteres Schalungsteil, ein zweites unteres Schalungsteil, ein drittes unteres Schalungsteil, ein erstes oberes Schalungsteil, ein zweites oberes Schalungsteil, ein drittes oberes Schalungsteil und einen als flächige Wassersperre ausgebildeten, horizontalen Blechmaterialstreifen auf. Der horizontale Blechmaterialstreifen weist einen ersten Blechmaterialstreifenabschnitt, einen zweiten Blechmaterialstreifenabschnitt und einen dritten Blechmaterialstreifenabschnitt auf, wobei der erste Blechmaterialstreifenabschnitt und der zweite Blechmaterialstreifenabschnitt einen Winkel δT12 miteinander einschließen, wobei 165° > δT12 > 30° gilt. Der erste Blechmaterialstreifenabschnitt und der dritte Blechmaterialstreifenabschnitt schließen einen Winkel δT13 miteinander ein, wobei 300° > δT13 > 30° gilt, während der zweite Blechmaterialstreifenabschnitt und der dritte Blechmaterialstreifenabschnitt einen Winkel δT23 miteinander einschließen, wobei 165° > δT23 > 30° gilt. Da die drei Blechmaterialstreifenabschnitte sich in einer gemeinsamen Ebene zu dem als flächige Wassersperre ausgebildeten Blechmaterialstreifen des T-Elements ergänzen, gilt immer die Bedingung δT12 + δT13 + δT23 = 360°.The flexibility of the formwork system according to the invention can be further increased if, according to a preferred embodiment, the angle element is designed as a T element or the three form elements standard element, angle element and A T-element is added to the fitting element.

Since the three sheet metal strip sections complement each other in a common plane to form the sheet metal strip of the T-element designed as a flat water barrier, the condition δ T12 + δ T13 + δ T23 = 360 ° always applies.

Da die verschiedenen Schalungsteile an den oben beschriebenen Blechmaterialstreifenabschnitten angeordnet sind, ergänzen sich auch die Winkel zwischen den verschiedenen Schalungsteilen zu 360°. Es gilt also αT12 + αT13 + αT23 = 360° und βT12 + βT13 + βT23 = 360°.The first lower shuttering part and the first upper shuttering part of the T-element are arranged in a common plane, the second lower shuttering part and the second upper shuttering part are arranged in a common plane, and the third lower shuttering part and the third upper shuttering part are in a common plane arranged.

Mit einem T-Element kann die Flexibilität des Baukastensystems weiter erhöht werden. In einfacher Weise können auf diese Weise Fugen abgeschalt werden, bei denen aus mindestens zwei unterschiedlichen Richtungen Fugenabschnitte aneinander stoßen. Im einfachsten Fall kann durch ein T-Element, drei Passelemente und drei Standardelemente eine Fuge abgeschalt werden, bei der ein linear verlaufender Fugenabschnitt mit einem auf diesem Fugenabschnitt senkrecht stehenden Fugenabschnitt zusammentrifft.

Da die vier Blechmaterialstreifenabschnitte sich in einer gemeinsamen Ebene zu dem als flächige Wassersperre ausgebildeten Blechmaterialstreifen des Kreuzelements ergänzen, gilt immer die Bedingung δK12 + δK23 + δK34 + δK41 = 360°.The first sheet metal strip section and the second sheet metal strip section of the cross element enclose an angle δ K12 with one another, where 110 °> δ K12 > 30 ° applies; the second sheet metal strip section and the third sheet metal strip section enclose an angle δ K23 with one another, where 110 °> δ K23 > 30 ° applies; the third sheet metal strip section and the fourth sheet metal strip section enclose an angle δ K34 with one another, with 110 °> δ K34 > 30 °; the fourth sheet metal strip section and the first sheet metal strip section enclose an angle δ K41 with one another, where 270 °> δ K41 > 30 ° applies. Since the four sheet metal strip sections complement each other in a common plane to form the sheet metal strip of the cross element designed as a flat water barrier, the condition δ K12 + δ K23 + δ K34 + δ K41 = 360 ° always applies.

Das erste untere Schalungsteil und das erste obere Schalungsteil des Kreuzelements sind in einer gemeinsamen Ebene angeordnet, das zweite untere Schalungsteil und das zweite obere Schalungsteil sind in einer gemeinsamen Ebene angeordnet, das dritte untere Schalungsteil und das dritte obere Schalungsteil sind in einer gemeinsamen Ebene angeordnet, und schließlich sind das vierte untere Schalungsteil und das vierte obere Schalungsteil in einer gemeinsamen Ebene angeordnet.The first lower formwork part and the first upper formwork part of the cross element are arranged in a common plane, the second lower formwork part and the second upper formwork part are arranged in a common plane, the third lower formwork part and the third upper formwork part are arranged in a common plane, and finally the fourth lower formwork part and the fourth upper formwork part are arranged in a common plane.

Das erste untere Schalungsteil und das zweite untere Schalungsteil des Kreuzelements schließen einen Winkel αK12 miteinander ein, wobei 110° > αK12 > 30° gilt; das erste obere Schalungsteil und das zweite obere Schalungsteil schließen einen Winkel βK12 miteinander ein, wobei 110° > βK12 > 30° gilt; das zweite untere Schalungsteil und das dritte untere Schalungsteil schließen einen Winkel αK23 miteinander ein, wobei 110° > αK23 > 30° gilt; das zweite obere Schalungsteil und das dritte obere Schalungsteil schließen einen Winkel βK23 miteinander ein, wobei 110° > βK23 > 30° gilt; das dritte untere Schalungsteil und das vierte untere Schalungsteil schließen einen Winkel αK34 miteinander ein, wobei 110° > αK34 > 30° gilt; das dritte obere Schalungsteil und das vierte obere Schalungsteil schließen einen Winkel βK34 miteinander ein, wobei 110° > βK34 > 30° gilt; das vierte untere Schalungsteil und das erste untere Schalungsteil schließen einen Winkel αK41 miteinander ein, wobei 270° > αK41 > 30° gilt; das vierte obere Schalungsteil und das erste obere Schalungsteil schließen einen Winkel βK41 miteinander ein, wobei 270° > βK41 > 30° gilt. Da die verschiedenen Schalungsteile an den oben beschriebenen Blechmaterialstreifenabschnitten angeordnet sind, ergänzen sich auch die Winkel zwischen den verschiedenen Schalungsteilen zu 360°. Es gilt also αK12 + αK23 + αK34 + αK41 = 360° und βK12 + βK23 + βK34 + βK41 = 360°.The first lower formwork part and the second lower formwork part of the cross element enclose an angle α K12 with one another, with 110 °> α K12 > 30 °; the first upper formwork part and the second upper formwork part form an angle β K12 with one another, where 110 °> β K12 > 30 ° applies; the second lower formwork part and the third lower formwork part form an angle α K23 with one another, where 110 °> α K23 > 30 ° applies; the second upper formwork part and the third upper formwork part form an angle β K23 with one another, where 110 °> β K23 > 30 ° applies; the third lower formwork part and the fourth lower formwork part form an angle α K34 with one another a, where 110 °> α K34 > 30 ° applies; the third upper formwork part and the fourth upper formwork part form an angle β K34 with one another, with 110 °> β K34 > 30 °; the fourth lower formwork part and the first lower formwork part form an angle α K41 with one another, where 270 °> α K41 > 30 ° applies; the fourth upper formwork part and the first upper formwork part form an angle β K41 with one another, where 270 °> β K41 > 30 ° applies. Since the various formwork parts are arranged on the sheet metal strip sections described above, the angles between the various formwork parts also add up to 360 °. The following applies: α K12 + α K23 + α K34 + α K41 = 360 ° and β K12 + β K23 + β K34 + β K41 = 360 °.

Der frei zugängliche Bereich der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts weist in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils eine Ausdehnung KA1 auf.The first sheet metal strip section of the cross element protrudes over a vertically oriented edge of the first upper formwork part, only the first surface of the first sheet metal strip section being freely accessible in the protruding area.

Die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils entspricht der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung KA1 des frei zugänglichen Bereichs der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts des Kreuzelements in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils und/oder die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils entspricht der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung KA2 des frei zugänglichen Bereichs der zweiten Oberfläche des zweiten Blechmaterialstreifenabschnitts des Kreuzelements in horizontaler Richtung in der Ebene des zweiten oberen Schalungsteils und/oder die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils entspricht der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung KA3 des frei zugänglichen Bereichs der dritten Oberfläche des dritten Blechmaterialstreifenabschnitts des Kreuzelements in horizontaler Richtung in der Ebene des dritten oberen Schalungsteils und/oder die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils entspricht der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung KA4 des frei zugänglichen Bereichs der vierten Oberfläche des vierten Blechmaterialstreifenabschnitts des Kreuzelements in horizontaler Richtung in der Ebene des vierten oberen Schalungsteils.The extension PA of the horizontal sheet metal strip of the fitting element in the horizontal direction in the plane of the formwork part corresponds to the sum of the extension SA1 of the freely accessible area of the first surface of the horizontal sheet metal strip of the standard element in the horizontal direction in the plane of the upper formwork part plus the extension KA1 of the freely accessible area the first surface of the first sheet metal strip section of the cross element in the horizontal direction in the plane of the first upper formwork part and / or the extension PA of the horizontal sheet metal material strip of the fitting element in the horizontal direction in the plane of the formwork part corresponds to the sum of the extension SA1 of the freely accessible area of the first surface of the horizontal sheet metal strip of the standard element in the horizontal direction in the plane of the upper formwork part plus extension KA2 of the freely accessible area of the second surface of the second Sheet metal strip section of the cross element in the horizontal direction in the plane of the second upper formwork part and / or the extension PA of the horizontal sheet metal material strip of the fitting element in the horizontal direction in the plane of the formwork part corresponds to the sum of the extension SA1 of the freely accessible area of the first surface of the horizontal sheet metal material strip of the standard element in the horizontal direction in the plane of the upper formwork part plus extension KA3 of the freely accessible area of the third surface of the third sheet metal strip section of the cross element in the horizontal direction in the plane of the third upper formwork part and / or the extension PA of the horizontal sheet metal material strip of the fitting element in the horizontal direction The level of the formwork part corresponds to the sum of the extent SA1 of the freely accessible area of the first surface of the horizontal sheet metal strip of the standard element in the horizontal Direction in the plane of the upper formwork part plus extension KA4 of the freely accessible area of the fourth surface of the fourth sheet metal strip section of the cross element in the horizontal direction in the plane of the fourth upper formwork part.

Mit einem Kreuzelement kann die Flexibilität des Baukastensystems weiter erhöht werden. In einfacher Weise können auf diese Weise Fugen abgeschalt werden, bei denen aus mindestens zwei unterschiedlichen Richtungen Fugenabschnitte aneinander stoßen. Im einfachsten Fall kann durch ein Kreuzelement, vier Passelemente und vier Standardelemente eine Fuge abgeschalt werden, bei der sich zwei linear verlaufende Fugenabschnitte kreuzen. Selbstverständlich können aber jede Art von Fugen abgeschalt werden, bei denen vier Fugenabschnitte in beliebigen Winkeln aufeinandertreffen.The flexibility of the modular system can be further increased with a cross element. In this way, joints can be switched off in a simple manner, in which joint sections abut one another from at least two different directions. In the simplest case, a cross element, four fitting elements and four standard elements can be used to shut off a joint in which two linear joint sections intersect. Of course, any type of joint can be shut off in which four joint sections meet at any angle.

Bevorzugt sind die verschiedenen Schalungsteile an dem jeweiligen Blechmaterialstreifen angeschweißt. Da die aus dem Schalungssystem gebildeten Abschalungen genügend Stabilität aufweisen müssen, um zum Einen problemlos auf der Baustelle aufgestellt werden zu können und um zum Anderen dem Betondruck nach Einfüllen des Ortbetons in die Schalung standhalten zu können, müssen Schalungsteile und Blechmaterialstreifen fest und dauerhaft miteinander verbunden sein. Besonders geeignet zur Sicherstellung einer stabilen Verbindung ist ein Verschweißen der einzelnen Teile.The various formwork parts are preferably welded to the respective strip of sheet metal. Since the shuttering formed from the shuttering system must have sufficient stability to be able to be set up on the construction site without any problems and to be able to withstand the concrete pressure after the in-situ concrete has been poured into the shuttering, shuttering parts and strips of sheet metal must be firmly and permanently connected to one another . Welding the individual parts is particularly suitable for ensuring a stable connection.

Besonders zweckmäßig ist es, wenn die beiden Schalungsteile des Standardelements, die vier Schalungsteile des Winkelelements, das Schalungsteil des Passelements, die sechs Schalungsteile des T-Elements und/oder die acht Schalungsteile des Kreuzelements jeweils eine Quer- und Längsstäbe umfassende Gittermatte und jeweils ein zwischen den Quer- und Längsstäben der Gittermatte eingeschweißtes durchbrochenes Metallblech umfassen. Besonders bevorzugt handelt es sich bei dem durchbrochenen Metallblech um ein Streckmetall- oder ein Lochblech.It is particularly expedient if the two formwork parts of the standard element, the four formwork parts of the angle element, the formwork part of the fitting element, the six formwork parts of the T-element and / or the eight formwork parts of the cross element each have a crossbar and a longitudinal bar and one between the transverse and longitudinal bars of the mesh mat include welded perforated metal sheet. The perforated metal sheet is particularly preferably an expanded metal sheet or a perforated sheet.

Bevorzugt sind die Querstäbe des Metallgitters mit den Längsstäben des Metallgitters an ihren Kreuzungspunkten verschweißt. Ebenso sind die Quer- und Längsstäbe des Metallgitters mit dem durchbrochenen Metallblech verschweißt. Die Durchbrechungen sind vorteilhafterweise einerseits groß genug gewählt, dass durch hindurchtretende Betonschlempe eine haltbare und beständige Verbindung des Betons der zwei aneinander grenzenden Betonierabschnitte gewährleistet wird, andererseits aber nicht so groß, dass der Beton des ersten Betonierabschnitts durch die Öffnungen hindurchfließen kann.The cross bars of the metal grid are preferably welded to the longitudinal bars of the metal grid at their crossing points. The transverse and longitudinal bars of the metal grid are also welded to the perforated metal sheet. The openings are advantageously chosen large enough on the one hand to ensure a durable and permanent connection of the concrete of the two adjacent concreting sections through the concrete slurry passing through, but on the other hand not so large that the concrete of the first concreting section can flow through the openings.

In Abhängigkeit von der Art des Einsatzes der Schalungselemente kann eine Optimierung der Dicke der Quer- und der Längsstäbe des Metallgitters und des Abstandes der Quer- und Längsstäbe zueinander vorgenommen werden. Je höher der zu erwartende Betondruck auf das Schalungselement ist umso dicker müssen die einzelnen Stäbe dimensioniert werden bzw. in umso geringerem Abstand zueinander müssen die Quer- und die Längsstäbe des Metallgitters verwendet werden.Depending on the type of use of the formwork elements, the thickness of the transverse and longitudinal bars of the metal grid and the distance between the transverse and longitudinal bars can be optimized. The higher the concrete pressure to be expected on the formwork element, the thicker the individual rods have to be dimensioned or the smaller the spacing between the transverse and longitudinal bars of the metal grid.

Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist der Blechmaterialstreifen des Standardelements, der Blechmaterialstreifen des Winkelelements, der Blechmaterialstreifens des Passelements, der Blechmaterialstreifen des T-Elements und/oder der Blechmaterialstreifen des Kreuzelements jeweils auf seiner ersten und/oder seiner zweiten Oberfläche zumindest teilweise, bevorzugt vollflächig, mit einer Dichtungsbeschichtung versehen. Durch eine Beschichtung und insbesondere durch eine vollflächige Beschichtung wird eine besonders gute Abdichtung gegen Wasser erreicht. Ein weiterer Vorteil ist insbesondere mit der Beschichtung der frei zugänglichen Abschnitte der Blechmaterialstreifen verbunden. Wie bereits beschrieben werden zur Bildung einer Abschalung ein Standardelement und ein Winkelelement, wahlweise aber auch ein T-Element oder ein Kreuzelement, so aufgestellt, dass die beiden frei zugänglichen Abschnitte der Blechmaterialstreifen miteinander fluchtend benachbart zueinander angeordnet sind. Da die Ausdehnung PA des horizontalen Blechmaterialstreifens des Passelements in horizontaler Richtung in der Ebene des Schalungsteils der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in horizontaler Richtung in der Ebene des oberen Schalungsteils plus Ausdehnung WA1 des frei zugänglichen Bereichs der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts des Winkelelements, oder auch des T-Elements oder des Kreuzelements, in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils entspricht, kann das Passelement zwischen Standardelement und Winkelelement eingeschoben werden. Die dem Schalungsteil des Passelements abgewandte Oberfläche des Blechmaterialstreifens des Passelements kommt dabei mit der ersten Oberfläche des horizontalen Blechmaterialstreifens des Standardelements in deren frei zugänglichen Bereich und mit der ersten Oberfläche des ersten Blechmaterialstreifenabschnitts des Winkelelements in deren frei zugänglichen Bereich in Kontakt. Sind nun die genannten Oberflächen alle mit einer Dichtungsbeschichtung, insbesondere mit einer vollflächig aufgetragenen Dichtungsbeschichtung ausgestattet, welche immer eine gewisse Klebrigkeit aufweist, so ist das Passelement nach dem Inkontaktbringen der entsprechenden Oberflächen fest mit dem Standardelement und fest mit dem Winkelelement, wahlweise dem T-Element oder dem Kreuzelement, verbunden, nämlich fest miteinander verklebt. Dadurch wird dem gesamten Schalungssystem schon beim Aufbau eine zusätzliche Stabilität verliehen. Die Schalungsteile der drei Elemente sind dann in einer gemeinsamen Ebene angeordnet und bilden eine durchgängige, geschlossene Schalung.According to a particularly preferred embodiment of the present invention, the sheet material strip of the standard element, the sheet material strip of the angle element, the sheet material strip of the fitting element, the sheet material strip of the T-element and / or the sheet material strip of the cross element is at least partially on its first and / or second surface, preferably over the entire surface, provided with a sealing coating. A particularly good seal against water is achieved by a coating and in particular by a full-surface coating. Another advantage is associated in particular with the coating of the freely accessible sections of the sheet metal material strips. As already described, the Forming a shuttering a standard element and an angle element, but optionally also a T-element or a cross element, set up in such a way that the two freely accessible sections of the sheet-metal material strips are aligned adjacent to one another. Since the extension PA of the horizontal sheet metal strip of the fitting element in the horizontal direction in the plane of the formwork part is the sum of the extension SA1 of the freely accessible area of the first surface of the horizontal sheet metal strip of the standard element in the horizontal direction in the plane of the upper formwork part plus the extension WA1 of the freely accessible area corresponds to the first surface of the first sheet metal strip section of the angle element, or also of the T-element or the cross element, in the horizontal direction in the plane of the first upper formwork part, the fitting element can be inserted between the standard element and the angle element. The surface of the sheet metal strip of the fitting element facing away from the formwork part of the fitting element comes into contact with the first surface of the horizontal sheet metal material strip of the standard element in its freely accessible area and with the first surface of the first sheet metal strip section of the angle element in its freely accessible area. If the surfaces mentioned are now all equipped with a sealing coating, in particular with a sealing coating applied over the entire surface, which always has a certain stickiness, then the fitting element is fixed to the standard element and fixed to the angle element, optionally the T-element, after the corresponding surfaces have been brought into contact or the cross element, connected, namely firmly glued together. This gives the entire formwork system additional stability when it is being set up. The formwork parts of the three elements are then arranged in a common plane and form a continuous, closed formwork.

Die Dichtungsbeschichtung kann grundsätzlich auf jede dem Fachmann bekannte Art auf den Blechmaterialstreifen aufgebracht werden. Bevorzugt weist die Dichtungsbeschichtung eine Klebstoffschicht zur Befestigung an dem jeweiligen Blechmaterialstreifen auf. Vor dem Aufbringen auf den Blechmaterialstreifen ist die Klebstoffschicht der Beschichtung üblicherweise mit einem Papierstreifen abgedeckt. Zur Befestigung kann der Papierstreifen dann einfach von der Beschichtung abgezogen und die Klebstoffschicht auf den Blechmaterialstreifen gedrückt werden. Es entsteht auf einfache Weise eine haltbare Verbindung zwischen der Beschichtung und dem Blechmaterialstreifen.The sealing coating can in principle be applied to the sheet metal strip in any manner known to the person skilled in the art. The sealing coating preferably has an adhesive layer for attachment to the respective strip of sheet metal. Before it is applied to the sheet metal strip, the adhesive layer of the coating is usually covered with a paper strip. For attachment, the paper strip can then simply be peeled off the coating and the adhesive layer can be pressed onto the sheet metal strip. A durable connection between the coating and the sheet metal strip is created in a simple manner.

Bei den nachfolgend noch näher beschriebenen Beschichtungen handelt es sich in der Regel um Materialien, die bei höheren Temperaturen ohne Zersetzung geschmolzen werden können. Als weitere bevorzugte Art der Aufbringung der Beschichtung auf den Blechmaterialstreifen kann daher das Aufspritzen des flüssigen Beschichtungsmaterials auf den Blechmaterialstreifen eingesetzt werden. Das Beschichtungsmaterial wird mit Hilfe einer Spritzdüse auf den Blechmaterialstreifen aufgespritzt, erkaltet dort und ergibt eine feste Dichtungsbeschichtung.The coatings described in more detail below are usually materials that can be melted at higher temperatures without decomposition. A further preferred type of application of the coating to the sheet metal strip can therefore be spraying the liquid coating material can be used on the sheet metal strips. The coating material is sprayed onto the sheet metal strip with the aid of a spray nozzle, where it cools down and results in a solid sealing coating.

Unabhängig von der Art des Aufbringens der Beschichtung auf den Blechmaterialstreifen ist die Beschichtung bis zu ihrem Einsatz als Teil einer Wassersperre mit einem Schutzüberzug ausgestattet. Die als Dichtungsbeschichtung eingesetzten Materialien verleihen der Beschichtung nämlich in jedem Fall eine klebrige Oberfläche, die sich in bekannter Weise mit dem vergossenen Beton gut verbindet. Zum Schutz dieser klebrigen Oberflächen wird in der Regel eine Papierschicht oder eine Kunststofffolie verwendet, die dann vor dem Vergießen des Betons von der Beschichtung abgezogen wird.Regardless of the type of application of the coating to the sheet metal strip, the coating is provided with a protective coating until it is used as part of a water barrier. The materials used as the sealing coating give the coating in any case a sticky surface that bonds well with the poured concrete in a known manner. To protect these sticky surfaces, a layer of paper or a plastic film is usually used, which is then peeled off the coating before the concrete is poured.

Wie üblich und dem Fachmann bekannt sorgt die Dichtungsbeschichtung beim Einsatz des erfindungsgemäßen Schalungssystems in wasserbeaufschlagten Betonteilen für eine Abdichtung der Fuge gegen Wasser. Dazu ist es besonders vorteilhaft, wenn sich die Oberflächen der Beschichtungen gut mit dem Beton auf beiden Seiten der Fuge verbinden. Gemäß einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung weist die Beschichtung daher eine klebrige Oberfläche auf, die sich dauerhaft mit dem angrenzenden Beton verbindet. Tritt der erwartete Schwund des Betons beim Aushärten auf, so wird die Dichtungsbeschichtung auf beiden Seiten der Schalung von dem Beton mitgezogen, wobei sich die Dicke der Beschichtung vergrößert. Auf diese Weise sorgt die Dichtungsbeschichtung für eine sichere Abdichtung der Fuge gegen Wasser.As is customary and known to those skilled in the art, when the formwork system according to the invention is used in concrete parts exposed to water, the sealing coating ensures that the joint is sealed against water. For this purpose, it is particularly advantageous if the surfaces of the coatings bond well with the concrete on both sides of the joint. According to a particularly preferred embodiment of the present invention, the coating therefore has a sticky surface that bonds permanently to the adjacent concrete. If the expected shrinkage of the concrete occurs during hardening, the sealing coating is pulled along by the concrete on both sides of the formwork, with the thickness of the coating increasing. In this way, the sealing coating ensures that the joint is reliably sealed against water.

Grundsätzlich kann als Dichtungsbeschichtung im Rahmen der vorliegenden Erfindung jede Art von Beschichtung verwendet werden, die die genannten Eigenschaften aufweist. Besonders gut geeignet sind Beschichtungen, die im Wesentlichen aus Butyl-Kautschuk, aus Bentonit, aus Bitumen-Kautschuk, aus einem Schmelzkleber oder aus einem quellbaren Kunststoff bestehen. Unter "quellbarem Kunststoff" werden alle üblichen, mit einem quellbaren Material ausgestatteten, thermoplastischen Elastomere verstanden. Quellbare Kunststoffe können in Folienform oder in Form von Bändern am Markt bezogen werden.In principle, any type of coating which has the properties mentioned can be used as a sealing coating in the context of the present invention. Coatings that essentially consist of butyl rubber, bentonite, bitumen rubber, a hot melt adhesive or a swellable plastic are particularly suitable. "Swellable plastic" is understood to mean all conventional thermoplastic elastomers equipped with a swellable material. Swellable plastics can be obtained on the market in film form or in the form of tapes.

Bei Butyl-Kautschuk handelt es sich um Polyisobutylen, das mit Harzen und Füllstoffen (z.B. Kalziumcarbonat) modifiziert ist. Bitumen-Kautschuk ist ein aus Erdöl gewonnenes Produkt, dessen genaue Zusammensetzung variiert. Bei Bentonit handelt es sich um eine quellfähige Mischung aus verschiedenen Tonmineralien. Als Hauptbestandteil ist Montmorillonit (60 - 80%) enthalten, Begleitmineralien sind Quarz, Glimmer, Feldspat, Pyrit oder auch Calcit.Butyl rubber is polyisobutylene that has been modified with resins and fillers (e.g. calcium carbonate). Bitumen rubber is a product made from petroleum, the exact composition of which varies. Bentonite is a swellable mixture of different clay minerals. The main component is montmorillonite (60 - 80%), accompanying minerals are quartz, mica, feldspar, pyrite or calcite.

Die Dicke der Beschichtung wird so gewählt, dass die Beschichtung einerseits auch bei Betonschwund an dem aushärtenden Beton haften bleibt, andererseits aber kein überflüssiges Beschichtungsmaterial auf die verlorene Schalung aufgetragen wird. Bevorzugt weist die Dichtungsbeschichtung eine Dicke zwischen 0,1 mm und 5 mm, besonders bevorzugt zwischen 0,15 mm und 3 mm, insbesondere eine Dicke zwischen 0,2 mm und 2 mm und insbesondere bevorzugt eine Dicke zwischen 0,5 mm und 1,5 mm auf. Als besonders vorteilhaft erweist sich eine Dicke der Dichtungsbeschichtung von rund 1 mm.The thickness of the coating is chosen so that, on the one hand, the coating adheres to the hardening concrete even if the concrete shrinks, but on the other hand, no superfluous coating material is applied to the lost formwork. The sealing coating preferably has a thickness between 0.1 mm and 5 mm, particularly preferably between 0.15 mm and 3 mm, in particular a thickness between 0.2 mm and 2 mm and particularly preferably a thickness between 0.5 mm and 1, 5 mm. A thickness of the sealing coating of around 1 mm has proven to be particularly advantageous.

Die genannten Beschichtungsmaterialen in den genannten Beschichtungsdicken können ihr Volumen bei Zugbelastung um wenigstens 50% und bis zu 100% vergrößern. Dadurch wird auch bei einem stärkeren Betonschwund eine gute Abdichtung der Fuge gewährleistet.The coating materials mentioned in the coating thicknesses mentioned can increase their volume by at least 50% and up to 100% under tensile loading. This ensures a good seal of the joint even if the concrete shrinks.

Entsprechen die Ausdehnungen aller vier frei zugänglichen Bereiche des Kreuzelements der Ausdehnung des Passelements, so kann das identische Passelement zur Verlängerung der Schalung in alle vier, durch das Kreuzelement vorgegebenen Richtungen verwendet werden.If the dimensions of all four freely accessible areas of the cross element correspond to the dimensions of the fitting element, the identical fitting element can be used to extend the formwork in all four directions given by the cross element.

Vorteilhafterweise umfasst das Schalungssystem mehrere Passelemente und mehrere Standardelemente. Dabei kann es sich um Passelemente und Standartelemente mit gleicher Ausdehnung handeln, aber auch um Passelemente und Standartelemente mit unterschiedlicher Ausdehnung. Die Vorteile der vorliegenden Erfindung kommen aber insbesondere dann zum Tragen, wenn eine möglichst geringe Zahl an unterschiedlichen Elementen zum Einsatz kommt.The formwork system advantageously comprises several fitting elements and several standard elements. This can be fitting elements and standard elements with the same expansion, but also fitting elements and standard elements with different expansion. However, the advantages of the present invention come into play in particular when the smallest possible number of different elements is used.

Bevorzugt springt der horizontale Blechmaterialstreifen des Standardelements über einen vertikal orientierten Rand des unteren Schalungsteils vor. In diesem vorspringenden Bereich ist nur die zweite Oberfläche des horizontalen Blechmaterialstreifens frei zugänglich ausgebildet, nicht aber die erste Oberfläche des horizontalen Blechmaterialstreifens. Der frei zugängliche Bereich der zweiten Oberfläche des horizontalen Blechmaterialstreifens weist in horizontaler Richtung in der Ebene des unteren Schalungsteils eine Ausdehnung SA2 auf. Diese Ausführungsform ist insbesondere dann mit Vorteilen verbunden, wenn die Ausdehnung SA2 des frei zugängliche Bereich der zweiten Oberfläche des horizontalen Blechmaterialstreifens der Ausdehnung SA1 des frei zugängliche Bereich der ersten Oberfläche des horizontalen Blechmaterialstreifens entspricht. In diesem Fall kann dasselbe Standardelement beliebig oft zur Verlängerung der Schalung in eine Richtung verwendet werden. Es braucht dazu lediglich die bevorzugt mit einer Dichtungsbeschichtung versehene frei zugängliche erste Oberfläche des einen Standardelements mit der ebenfalls bevorzugt mit einer Dichtungsbeschichtung versehenen frei zugänglichen zweiten Oberfläche des anderen Standardelements in Kontakt gebracht zu werden.The horizontal sheet metal strip of the standard element preferably projects over a vertically oriented edge of the lower formwork part. In this protruding area, only the second surface of the horizontal sheet metal strip is freely accessible, but not the first surface of the horizontal sheet metal strip. The freely accessible area of the second surface of the horizontal sheet metal strip has an extension SA2 in the horizontal direction in the plane of the lower formwork part. This embodiment is particularly advantageous when the expansion SA2 of the free accessible area of the second surface of the horizontal sheet metal strip corresponds to the extent SA1 of the freely accessible area of the first surface of the horizontal sheet metal strip. In this case, the same standard element can be used as often as required to extend the formwork in one direction. For this purpose, the freely accessible first surface of the one standard element, which is preferably provided with a sealing coating, needs to be brought into contact with the freely accessible second surface of the other standard element, which is likewise preferably provided with a sealing coating.

The fitting element is arranged between the standard element and the angle element in such a way that the upper formwork part of the standard element, the formwork part of the fitting element and the first upper formwork part of the angle part lie in one plane, the surface of the sheet metal strip of the fitting element facing away from the formwork part of the fitting element with the first Surface of the horizontal sheet metal strip of the standard element and is in contact with the first surface of the first sheet metal strip section of the angle element.

Besonders zweckmäßig im Hinblick auf die Stabilität der Standardelemente, Passelemente, Winkelelemente, T-Elemente und Kreuzelemente ist es, wenn die einzelnen Schalungselemente im Bereich ihrer Begrenzungskanten einen Quer- oder Längsstab der bevorzugt als Bestandteil der Schalungselemente verwendeten Gittermatte aufweisen.It is particularly useful with regard to the stability of the standard elements, fitting elements, angle elements, T-elements and cross elements if the individual formwork elements have a transverse or longitudinal bar of the lattice mat preferably used as part of the formwork elements in the area of their boundary edges.

Die Figur 4 zeigt eine perspektivische Ansicht eines Passelements P zur Verwendung in einem erfindungsgemäßen Schalungssystem.

Der horizontale Blechmaterialstreifen P2 ist im wesentlichen senkrecht zu der Ebene des Schalungsteils P1 ausgerichtet. Die erste Oberfläche P2a des horizontalen Blechmaterialstreifens ist dem Schalungsteil P1 zugewandt, während eine zweite Oberfläche P2b des horizontalen Blechmaterialstreifens dem Schalungsteil P1 abgewandt ist.

Anhand der Figuren 5A und 5B kann das Zusammenspiel der in den Figuren 1 bis 4 gezeigten Elemente Standardelement S, Winkelelement W und Passelement P erläutert werden. Die Figur 5A zeigt eine seitliche Ansicht einer aus einem Schalungssystem gemäß der vorliegenden Erfindung zusammengesetzten Schalung vor dem Einfügen des Passelements P, während die Figur 5B dieselbe Schalung nach dem Einfügen des Passelements P zeigt.Based on Figures 5A and 5B can the interaction of the Figures 1 to 4 elements shown standard element S, angle element W and fitting element P are explained. the Figure 5A shows a side view of a formwork assembled from a formwork system according to the present invention before the insertion of the fitting element P, while the Figure 5B shows the same formwork after the fitting element P has been inserted.

In der Figur 5A sind die Elemente einer Schalung für den Betonbau gemäß der vorliegenden Erfindung, nämlich Standardelement S, Winkelelement W ein Passelement P dargestellt. Alle drei Elemente weisen einen als Wassersperre ausgebildeten, im eingebauten Zustand in horizontaler Richtung verlaufenden Blechmaterialstreifen auf. Die dem oberen Schalungsteil S2 zugewandte Oberfläche S3a des Blechmaterialstreifens S3 des Standardelements S und auch die dem ersten oberen Schalungsteil WO1 zugewandte Oberfläche W31a des ersten Blechmaterialstreifenabschnitss des Blechmaterialstreifens W3 des Winkelelements W ist frei zugänglich ausgebildet, also nicht mit einem Schalungsteil verbunden.In the Figure 5A the elements of a formwork for concrete construction according to the present invention, namely standard element S, angle element W and a fitting element P are shown. All three elements have a strip of sheet metal material which is designed as a water barrier and runs in the horizontal direction when installed. The surface S3a of the sheet metal strip S3 of the standard element S facing the upper formwork part S2 and also the surface W31a of the first sheet metal strip section of the sheet metal material strip W3 of the angle element W facing the first upper formwork part WO1 is freely accessible, i.e. not connected to a formwork part.

Zur Bildung einer Abschalung werden das Standardelement S und das Winkelelement W so aufgestellt, dass die beiden frei zugänglichen Oberflächen S3a, W31a der Blechmaterialstreifen S3, W3 miteinander fluchtend benachbart zueinander angeordnet sind. Die Ausdehnung des horizontalen Blechmaterialstreifens P2 des Passelements P in horizontaler Richtung in der Ebene des Schalungsteils P1 ist mit PA bezeichnet. Die Ausdehnung des frei zugänglichen Bereichs der ersten Oberfläche S3a des horizontalen Blechmaterialstreifens S3 des Standardelements S in horizontaler Richtung in der Ebene des oberen Schalungsteils S2 beträgt SA1. Schließlich ist die Ausdehnung des frei zugänglichen Bereichs der ersten Oberfläche W31a des ersten Blechmaterialstreifenabschnitts des Winkelelements W in horizontaler Richtung in der Ebene des ersten oberen Schalungsteils WO1 mit WA1 in der Figur 5A dargestellt.To form a shuttering, the standard element S and the angle element W are set up in such a way that the two freely accessible surfaces S3a, W31a of the sheet-metal material strips S3, W3 are arranged adjacent to one another in alignment with one another. The extension of the horizontal sheet metal strip P2 of the fitting element P in the horizontal direction in the plane of the formwork part P1 is denoted by PA. The extent of the freely accessible area of the first surface S3a of the horizontal sheet metal strip S3 of the standard element S in the horizontal direction in the plane of the upper formwork part S2 is SA1. Finally, the extent of the freely accessible area of the first surface W31a of the first sheet metal strip section of the angle element W is in the horizontal direction in the plane of the first upper formwork part WO1 with WA1 in FIG Figure 5A shown.

Da die Ausdehnung PA des horizontalen Blechmaterialstreifens P2 des Passelements P der Summe aus Ausdehnung SA1 des frei zugänglichen Bereichs der ersten Oberfläche S3a des horizontalen Blechmaterialstreifens des Standardelements S plus Ausdehnung WA1 des frei zugänglichen Bereichs der ersten Oberfläche W31a des ersten Blechmaterialstreifenabschnitts des Winkelelements W entspricht, kann das Passelement P zwischen das Standardelement S und das Winkelelement W eingeschoben werden. Diese Situation ist in der Figur 5B dargestellt. Die oberen Schalungsteile S2, P1 und WO1 der drei Elemente wie auch die unteren Schalungsteile S1 und WU1 von Standardelement bzw. Winkelelement sind dann in einer gemeinsamen Ebene angeordnet und bilden eine durchgängige, geschlossene Schalung.Since the extent PA of the horizontal sheet metal strip P2 of the fitting element P corresponds to the sum of the extent SA1 of the freely accessible area of the first surface S3a of the horizontal sheet metal strip of the standard element S plus the extent WA1 of the freely accessible area of the first surface W31a of the first sheet metal strip section of the angle element W, can the fitting element P can be inserted between the standard element S and the angle element W. This situation is in the Figure 5B shown. The upper formwork parts S2, P1 and WO1 of the three elements as well as the lower formwork parts S1 and WU1 of the standard element or angle element are then arranged in a common plane and form a continuous, closed formwork.

Durch das Winkelelement W ist nun die Möglichkeit geschaffen, die Schalung durch Anschluss eines weiteren Standardelements und Einfügen eines weiteren Passelements in einer Richtung senkrecht zu der oben beschriebenen Schalungsebene fortzuführen. Die drei Schalungselemente Standardelement S, Winkelelement W und Passelement P stellen somit ein Baukastensystem zur Verfügung, mit dessen Hilfe eine große Vielfalt an nichtlinear verlaufenden Fugen abgeschalt werden können. Es ist keine an die jeweilige Einbausituation angepasste Konfektionierung erforderlich. Da die Elemente in großer Stückzahl vorgefertigt werden, ergeben sich deutliche Kosteneinsparungen im Vergleich zu individuell gefertigten Schalungen.The angle element W now makes it possible to continue the formwork by connecting a further standard element and inserting a further fitting element in a direction perpendicular to the formwork plane described above. The three formwork elements standard element S, angle element W and fitting element P thus provide a modular system with the help of which a large variety of non-linear joints can be closed. No assembly adapted to the respective installation situation is required. Since the elements are prefabricated in large numbers, there are significant cost savings compared to individually manufactured formwork.

Die Blechmaterialstreifen S3, W3, P2 des Standardelements S, des Winkelelements W und des Passelements P sind an ihren Oberflächen vollflächig mit einer Dichtungsbeschichtung (nicht dargestellt) aus Butyl-Kautschuk ausgestattet. Da eine solche Dichtungsbeschichtung eine gewisse Klebrigkeit aufweist, sind die Blechmaterialstreifen S3 und W3 über ihre Oberflächen S3a bzw. W31a nach dem Einfügen des Passelements P zwischen das Standardelement S und das Winkelelement W mit der Oberfläche P2b des Blechmaterialstreifens P2 des Passelements P verklebt. Dadurch wird dem gesamten Schalungssystem zusätzliche Stabilität verliehen.The sheet metal strips S3, W3, P2 of the standard element S, the angle element W and the fitting element P are provided with a sealing coating (not shown) made of butyl rubber over their entire surface. Since such a sealing coating has a certain stickiness, the sheet-metal material strips S3 and W3 are glued to the surface P2b of the sheet-metal material strip P2 of the fitting element P via their surfaces S3a and W31a, respectively, after the fitting element P has been inserted between the standard element S and the angle element W. This gives the entire formwork system additional stability.

Die Figur 6 zeigt eine perspektivische Ansicht eines T-Elements T zur Verwendung in einem Schalungssystem gemäß der vorliegenden Erfindung. Ein solches T-Element kann zusätzlich zu dem in Figur 3 dargestellten Winkelelement W eingesetzt werden oder es kann als spezifische Variante das Winkelelements W verwendet werden.the Figure 6 shows a perspective view of a T-element T for use in a formwork system according to the present invention. Such a T-element can be used in addition to the in Figure 3 angle element W shown can be used or the angle element W can be used as a specific variant.

Das T-Element T weist ein erstes unteres Schalungsteil TU1, ein zweites unteres Schalungsteil TU2, ein drittes unteres Schalungsteil TU3, ein erstes oberes Schalungsteil TO1, ein zweites oberes Schalungsteil TO2, ein drittes oberes Schalungsteil TO3 und einen als flächige Wassersperre ausgebildeten, horizontalen Blechmaterialstreifen T3 auf, wobei der horizontale Blechmaterialstreifen T3 einen ersten Blechmaterialstreifenabschnitt T31, einen zweiten Blechmaterialstreifenabschnitt T32 und einen dritten Blechmaterialstreifenabschnitt T33 aufweist. Die Schalungsteile TU1, TU2, TU3, TO1, TO2, TO3 bestehen jeweils aus einer Quer- und Längsstäbe umfassenden Gittermatte und jeweils einem zwischen den Quer- und Längsstäben der Gittermatte eingeschweißten Streckmetallblech.The T-element T has a first lower shuttering part TU1, a second lower shuttering part TU2, a third lower shuttering part TU3, a first upper shuttering part TO1, a second upper shuttering part TO2, a third upper shuttering part TO3 and a horizontal sheet metal strip designed as a flat water barrier T3, the horizontal sheet metal strip T3 having a first sheet metal strip section T31, a second sheet metal strip section T32 and a third Has sheet metal strip portion T33.

Die Figur 6 zeigt also eine Ausführungsform des T-Elements, deren Form exakt einem "T" entspricht. Es soll aber nochmals erwähnt werden, dass die vorliegende Erfindung eine Vielzahl weiterer Ausführungsformen umfasst, bei denen die Winkel δT12, δT13 und δT23 von den Werten 90° bzw. 180° abweichen gilt. Beispielsweise kann der Winkel δT13 zwar 180° betragen, die Winkel δT12 und δT23 können aber von 90° abweichen. In diesem Fall besteht das T-Element zwar weiterhin aus einem Flansch und einem Steg, diese stehen aber nicht senkrecht aufeinander.The first sheet metal strip section T31 and the second sheet metal strip section T32 enclose an angle δ T12 = 90 ° with one another, while the first sheet metal material strip section T31 and the third sheet metal strip section T33 form an angle δ T13 = 180 ° with one another and the second sheet metal material strip section T32 and the third sheet metal strip section T33 form a Include angle δ T23 = 90 ° with one another. the Figure 6 shows an embodiment of the T-element, the shape of which corresponds exactly to a "T". However, it should be mentioned again that the present invention comprises a large number of further embodiments in which the angles δ T12 , δ T13 and δ T23 differ from the values 90 ° and 180 °. For example, the angle δ T13 can be 180 °, but the angles δ T12 and δ T23 can deviate from 90 °. In this case, the T-element still consists of a flange and a web, but these are not perpendicular to one another.

Das erste untere Schalungsteil TU1 und das erste obere Schalungsteil TO1 sind in einer gemeinsamen Ebene angeordnet, das zweite untere Schalungsteil TU2 und das zweite obere Schalungsteil TO2 sind in einer gemeinsamen Ebene angeordnet und schließlich sind auch das dritte untere Schalungsteil TU3 und das dritte obere Schalungsteil TO3 in einer gemeinsamen Ebene angeordnet. Das erste untere Schalungsteil TU1 und das zweite untere Schalungsteil TU2 schließen einen Winkel αT12 = 90° miteinander ein, das erste obere Schalungsteil TO1 und das zweite obere Schalungsteil TO2 schließen einen Winkel βT12 von ebenfalls 90° miteinander ein, das erste untere Schalungsteil TU1 und das dritte untere Schalungsteil TU3 schließen einen Winkel αT13 = 180° miteinander ein, das erste obere Schalungsteil TO1 und das dritte obere Schalungsteil TO3 schließen einen Winkel βT13 von ebenfalls 180° miteinander ein, das zweite untere Schalungsteil TU2 und das dritte untere Schalungsteil TU3 schließen einen Winkel αT23 = 90° miteinander ein, das zweite obere Schalungsteil TO2 und das dritte obere Schalungsteil TO3 schließen einen Winkel βT23 von ebenfalls 90° miteinander ein.The first lower shuttering part TU1 and the first upper shuttering part TO1 are arranged in a common plane, the second lower shuttering part TU2 and the second upper shuttering part TO2 are arranged in a common plane and finally the third lower shuttering part TU3 and the third upper shuttering part TO3 are also arranged arranged in a common plane. The first lower formwork part TU1 and the second lower formwork part TU2 form an angle α T12 = 90 ° with one another, the first upper formwork part TO1 and the second upper formwork part TO2 form an angle β T12 of 90 ° with one another, the first lower formwork part TU1 and the third lower shuttering part TU3 form an angle α T13 = 180 ° with one another, the first upper shuttering part TO1 and the third upper shuttering part TO3 also form an angle β T13 of 180 ° with one another, the second lower shuttering part TU2 and the third lower shuttering part TU3 enclose an angle α T23 = 90 ° with one another, the second upper formwork part TO2 and the third upper formwork part TO3 form an angle β T23 of also 90 ° with one another.

Die Winkel zwischen den einzelnen Schalungsteilen entsprechen also den Winkeln zwischen den entsprechenden Blechmaterialstreifen. Wie bereits im Zusammenhang mit der Anordnung der Blechmaterialstreifen relativ zueinander erläutert, handelt es sich dabei um eine spezifische Ausführungsform. Die Winkel können auch abweichende Werte annehmen.The angles between the individual formwork parts therefore correspond to the angles between the corresponding sheet metal strips. As already explained in connection with the arrangement of the sheet metal strips relative to one another, this is a specific embodiment. The angles can also have different values.
