Description

Die Erfindung bezieht sich auf ein Schalungselement der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a formwork element explained in the preamble of claim 1 Art.

Ein derartiges Schalungselement ist aus der EP 532 908 bekannt. Das bekannte Schalungselement ist als Platten- oder Wandabschalung ausgebildet und enthält zwei Schalungswandungen und eine zwischen den Schalungswandungen befestigte Halterung für eine Fugensperre, insbesondere ein Fugenband. Die Halterung ist als korbartige Bügelkonstruktion ausgestaltet und dient gleichzeitig zum Verbinden der beiden Schalungswandungen miteinander, wobei die Schalungswandungen etwa mittig an den Stegen der Halterung befestigt sind, so dass die Halterung beidseitig über die Schalungswandungen vorsteht. In die Halterung wird das Fugenband eingelegt, und die beiden Schenkel der U-förmigen Halterung werden miteinander verbunden, bevorzugt verrödelt, um das Fugenband in der Halterung festzulegen. Die Halterung besteht aus einer gebogenen Baustahlmatte und ist demzufolge relativ schwer, was auch das Gewicht der Schalung erhöht und damit die Handhabung erschwert.Such a formwork element is from the EP 532 908 known. The known formwork element is designed as a plate or Wandabschalung and contains two formwork walls and a fixed between the formwork walls bracket for a joint barrier, in particular a joint tape. The holder is designed as a basket-like bracket construction and serves at the same time for connecting the two formwork walls with each other, wherein the formwork walls are attached approximately centrally to the webs of the holder, so that the holder protrudes on both sides of the formwork walls. In the holder, the joint tape is inserted, and the two legs of the U-shaped bracket are connected to each other, preferably verkrödelt to set the joint tape in the holder. The holder consists of a curved steel mesh and is therefore relatively heavy, which also increases the weight of the formwork and thus complicates handling.

Der Erfindung liegt somit die Aufgabe zugrunde, ein besser handhabbares Schalungselement zu schaffen.The invention is therefore an object of the invention to provide a better manageable formwork element.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die erfindungsgemäße Ausgestaltung kann das Gewicht des Schalungselementes entscheidend reduziert und somit die Handhabung erleichtert werden. Insbesondere kann das Fugenband oder das Fugenblech besonders einfach eingeführt werden.The inventive design, the weight of the formwork element can be significantly reduced and thus the handling can be facilitated. In particular, the joint tape or the joint plate can be introduced particularly easily.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Bevorzugt ist das Materialstück mit einer der Schalungswandungen fest verbunden, so dass es unverlierbar ist.Preferably, the piece of material is firmly connected to one of the formwork walls, so that it is captive.

Obwohl bei bestimmten Ausführungsformen ein einziges Materialstück reicht, um insbesondere ein Fugenband sicher zu befestigen, sind zwei flächige Materialstücke bevorzugt, die die Wassersperreinrichtung zwischen sich aufnehmen können.Although in certain embodiments a single piece of material is sufficient, in particular to secure a joint tape securely, two flat pieces of material are preferred, which can accommodate the Wasserperreinrichtung between them.

Für eine noch bessere Lagesicherung können die beiden Materialstücke, bevorzugt durch Verrödeln, miteinander verbunden werden.For an even better position assurance, the two pieces of material, preferably by Verrödeln, are interconnected.

Ein besonders bevorzugtes Ausführungsbeispiel besteht darin, zwei Materialstücke zu verwenden, wobei eines der Materialstücke mit der Schalungswandung fest verbunden ist und das andere Materialstück nur lose beigelegt wird, d.h. an der Schalungswandung nicht fest verbunden ist.A particularly preferred embodiment is to use two pieces of material, wherein one of the pieces of material is firmly connected to the formwork wall and the other piece of material is added only loosely, i. is not firmly connected to the formwork wall.

Ein bevorzugtes Material für das Materialstück ist ein Streckmetallblech, das sowohl relativ leicht im Gewicht als auch gut zu verarbeiten und gut zu handhaben ist.A preferred material for the piece of material is an expanded metal sheet that is relatively light in weight as well as easy to handle and handle.

Es kann weiterhin eine Positioniereinrichtung für die Wassersperreinrichtung vorgesehen sein, wodurch unter Umständen ein zweites Materialstück entbehrlich ist. Diese Positioniereinrichtung kann eine trogartig umgebogene Randkante des Materialstücks im Inneren des Freiraums enthalten, die kaum zusätzliches Gewicht bringt und einfach herstellbar ist.It may further be provided a positioning device for the water barrier device, whereby under certain circumstances, a second piece of material is unnecessary. This positioning device may include a trough-like bent over edge of the piece of material in the interior of the free space, which brings little additional weight and is easy to produce.

Besonders gewichtssparend ist eine Brücke, die eine Mehrzahl in Längsrichtung beabstandeter, mit beiden Schalungswandungen verbundener Bügel enthält.Particularly weight-saving is a bridge, which contains a plurality of longitudinally spaced, connected to two formwork walls bracket.

Die Schalungswandungen sind bevorzugt aus Streckmetallen.The formwork walls are preferably made of expanded metals.

Durch eine Abwinklung des Materialstücks können Hohlräume unter der Fugensperre besser vermieden werden.By angling of the piece of material cavities under the joint barrier can be better avoided.

Fig. 1 zeigt in schematischer, perspektivischer Darstellung ein erstes Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 1. Das Schalungselement 1 ist im dargestellten Ausführungsbeispiel als Fugenschalungselement für eine Wand- oder Plattenabschalung ausgebildet. Das Schalungselement 1 enthält eine erste Schalungswandung 2 und eine zweite Schalungswandung 3, die aus einem flächigen Schalungsmaterial bestehen, in der gleichen Ebene liegen und zwischen sich eine Halterung 4 für eine Fugensperre bzw. Wassersperreinrichtung 4a (Fig. 2) in Form eines Fugenbleches oder eines elastomeren Fugenbandes oder dgl. einschließen. Fig. 1 shows a schematic, perspective view of a first embodiment of a formwork element according to the invention 1. The formwork element 1 is formed in the illustrated embodiment as a joint formwork element for a wall or Plattenabschalung. The formwork element 1 includes a first formwork wall 2 and a second formwork wall 3, which consist of a sheet-like formwork material, lie in the same plane and between them a holder 4 for a joint barrier or water barrier device 4a (Fig. Fig. 2 ) in the form of a joint plate or an elastomeric joint tape or the like. Include.

Die Schalungswandungen 2, 3 sind betondurchlässig und enthalten Streckmetall. Im bevorzugten Ausführungsbeispiel ist jede der Schalungswandungen 2, 3 aus einer ersten und einer zweiten Tafel 5a und 5b (Fig. 1A) eines Streckmetallbleches gefertigt. Die Tafeln 5a, 5b liegen flächig aufeinander und sind aneinander befestigt, bevorzugt miteinander verschweißt. Als Streckmetallblech kann jedes herkömmliche und handelsübliche Streckmetallblech geeigneter Maschenweite eingesetzt werden. Im dargestellten Ausführungsbeispiel besteht die erste Tafel 5a aus einem Streckmetallblech mit großer Maschenweite, d.h. große Öffnungen und demzufolge auch relativ gesehen breiten Stegen und Knoten. Dagegen weist das zweite Streckmetallblech 5b eine kleinere Maschenweite auf, die so gewählt wurde, dass Beton zurückgehalten wird, aber leicht durch die Öffnungen quellen kann, um eine raue Oberfläche zu erzeugen, die sich gut mit einem weiteren Betonierabschnitt verbindet. Bevorzugt weist das grobe Streckmetallblech 5a eine Maschenweite von 50 x 37, d.h. einer Länge einer größeren Diagonale der Öffnung von 50 mm und einer Länge der kleinere Diagonale der Öffnung von 37 mm auf. Das feinere Streckmetallblech 5b weist dagegen eine Maschenweite von bevorzugt 16 x 6 auf.The formwork walls 2, 3 are permeable to concrete and contain expanded metal. In the preferred embodiment, each of the shuttering walls 2, 3 is composed of a first and a second panel 5a and 5b (FIG. Fig. 1A ) made of expanded metal sheet. The panels 5a, 5b lie flat against one another and are fastened to one another, preferably welded together. As expanded metal sheet, any conventional and commercially available expanded metal sheet of suitable mesh size can be used. In the illustrated embodiment, the first panel 5a consists of an expanded metal sheet with a large mesh size, ie large openings and consequently also relatively seen wide webs and knots. In contrast, the second expanded metal sheet 5b has a smaller mesh size, which has been chosen so that concrete is retained but can easily swell through the openings to create a rough surface that bonds well with another concreting section. Preferably, the coarse expanded metal sheet 5a has a mesh size of 50 × 37, ie a length of a larger diagonal of the opening of 50 mm and a length of the smaller diagonal of the opening of 37 mm. By contrast, the finer expanded metal sheet 5b has a mesh size of preferably 16 × 6.

Die beiden Schalungswandungen 2, 3 sind über eine Brücke 6 miteinander verbunden und in ihrer fluchtenden Anordnung in einer gemeinsamen Ebene gehalten. Die Brücke 6 enthält eine Mehrzahl von Bügeln 6a, die im Wesentlichen omegaförmig ausgebildet sind, d.h. eine im Wesentlichen U-förmige, mittlere Auswölbung 7, die einen Freiraum 8 umgibt, und zwei seitliche Schenkel 9a, 9b umfassen. Die seitlichen Schenkel 9a, 9b sind bevorzugt gerade und zur Befestigung, bevorzugt Verschweißung, an den Schalungswandungen 2, 3 ausgebildet. Beide Schalungswandungen 2, 3 werden so mit der Brücke 6 verbunden, dass die Brücke 6, d.h. der Freiraum 8, an nur einer Seite beider Schalungswandungen 2, 3 vorsteht und zwischen den Schalungswandungen 2, 3 ein Abstand verbleibt, der einen Eingang 10 in den Freiraum 8 bildet. Dabei können sich die Bügel 6a mit ihren Schenkeln 9a, 9b über die gesamte Breite der Schalungswandungen 2, 3 oder nur einen Teil davon, entweder an der einen oder der anderen Seite erstrecken.The two formwork walls 2, 3 are connected to each other via a bridge 6 and held in their aligned arrangement in a common plane. The bridge 6 includes a plurality of brackets 6a, which are substantially omega-shaped, i. a substantially U-shaped central bulge 7, which surrounds a free space 8, and two lateral legs 9a, 9b. The lateral legs 9a, 9b are preferably straight and designed for attachment, preferably welding, to the shuttering walls 2, 3. Both formwork walls 2, 3 are connected to the bridge 6 so that the bridge 6, i. the free space 8 protrudes on only one side of both formwork walls 2, 3 and a distance remains between the formwork walls 2, 3, which forms an entrance 10 into the free space 8. In this case, the bracket 6a may extend with their legs 9a, 9b over the entire width of the formwork walls 2, 3 or only a part thereof, either on one side or the other.

Der Abstand der Bügel 6a in Längsrichtung der Schalungswandungen 2, 3, d. h. in Richtung senkrecht zur Fig. 2, kann nach Festigkeitsgesichtspunkten gewählt werden und muss nicht sehr eng sein. Dadurch kann Beton ungehindert durch die Brücke 6 hindurchtreten und diese gut im Beton verankern.The distance of the bracket 6a in the longitudinal direction of the shuttering walls 2, 3, ie in the direction perpendicular to Fig. 2 , can be chosen according to strength considerations and does not have to be very tight. This allows concrete to pass unhindered through the bridge 6 and anchor it well in the concrete.

Die Halterung 4 enthält ein erstes Materialstück 11, das im dargestellten Ausführungsbeispiel als rechteckiger Streifen mit einer Breite b vorliegt. Das Materialstück 11 ist bevorzugt ebenfalls betondurchlässig und besteht in einem besonders bevorzugten Ausführungsbeispiel ebenfalls aus einem Streckmetallblech. Das Streckmetallblech kann jede Maschenweite aufweisen, weist jedoch bevorzugt eine etwas gröbere Maschenweite auf, damit Beton ungehindert und vollständig hindurchtreten kann, um die Wassersperreinrichtung einzuschließen.The holder 4 includes a first piece of material 11, which is present in the illustrated embodiment as a rectangular strip with a width b. The piece of material 11 is preferably also permeable to the concrete and, in a particularly preferred embodiment, likewise consists of an expanded metal sheet. The expanded metal sheet can have any mesh size, but preferably has a slightly coarser mesh size so that concrete can pass unhindered and completely to enclose the water barrier device.

Das Materialstück 11 ist mit einer der beiden Schalungswandungen 2, 3, im vorliegenden Ausführungsbeispiel der Schalungswandung 3, fest verbunden. Besteht das Materialstück 11 und die Schalungswandung 3 aus schweißbarem Material, so ist eine Verschweißung bevorzugt. Das Materialstück 11 liegt auf der die Eingangsöffnung 10 begrenzenden Kante der Schalungswandung 3 derart auf, dass das Materialstück 11 an beiden Seiten über die Schalungswandung 3 (und natürlich auch über die Schalungswandung 2) aus der gemeinsamen Ebene der Schalungswandungen 2, 3 vorsteht. Bevorzugt erfolgt die Verbindung zwischen dem Materialstück 11 und der Schalungswandung 3 in der Längsmittellinie des Materialstücks 11. Dabei ist die Breite b so auf die Tiefe des Freiraums 8 abgestimmt, dass das Materialstück 11 in den Freiraum hineinragt und in diesem Freiraum aufgenommen ist. Das Materialstück 11 ist nicht fest mit der Brücke 6 verbunden, d.h. nicht mit ihr verschweißt.The piece of material 11 is fixedly connected to one of the two shuttering walls 2, 3, in the present embodiment of the shuttering wall 3. If the piece of material 11 and the formwork wall 3 of weldable material, so a welding is preferred. The piece of material 11 rests on the edge of the shuttering wall 3 delimiting the inlet opening 10 in such a way that the piece of material 11 protrudes from the common plane of the shuttering walls 2, 3 on both sides via the shuttering wall 3 (and of course also via the shuttering wall 2). Preferably, the connection between the piece of material 11 and the formwork wall 3 in the longitudinal center line of the piece of material 11. The width b is matched to the depth of the free space 8, that the piece of material 11 protrudes into the space and is accommodated in this space. The piece of material 11 is not fixedly connected to the bridge 6, i. not welded with it.

Die Halterung 4 enthält weiterhin ein zweites Materialstück 12, das in Fig. 1 nur gestrichelt dargestellt ist, um die Darstellung übersichtlich zu halten. Das zweite Materialstück 12 ist bevorzugt identisch mit dem ersten Materialstück 11 ausgebildet, ist jedoch weder mit der Schalungswandung 3 noch mit der Schalungswandung 2 noch mit der Brücke 6 direkt und fest verbunden. Das Materialstück 12 wird nur lose beigelegt und gegebenenfalls mit dem ersten Materialstück 11 locker, z.B. durch Verröfeln, verbunden.The holder 4 further includes a second piece of material 12, which in Fig. 1 only dashed lines to keep the presentation clearly. The second piece of material 12 is preferably formed identically to the first piece of material 11, but is not directly and firmly connected to either the shuttering wall 3, the shuttering wall 2 or the bridge 6. The piece of material 12 is enclosed only loosely and optionally loosely connected to the first piece of material 11, for example by Verröfeln.

Im Gebrauch wird zunächst eine Wassersperreinrichtung 4a, wie ein Fugenband oder ein Fugenblech oder dgl., durch die Öffnung 10 in den Freiraum 8 so weit eingeschoben, dass seine Längsmittellinie etwa mit den Schalungswandungen 2, 3 fluchtend ausgerichtet ist, und auf das erste Materialstück 11 abgelegt. Dann wird das zweite Materialstück 12 so eingeschoben, dass die Wassersperreinrichtung 4a zwischen den beiden Materialstücken 11 und 12 aufgenommen ist. Die Materialstücke 11 und 12 können dann in geeigneter Weise miteinander verbunden werden, entweder durch gesondert vorgesehene Verbindungsmittel oder, wie dargestellt, durch einen einfachen Rödeldraht 13. Damit ist die Fugensperre 4a sicher in der Halterung 4 aufgenommen.In use, first a water barrier device 4a, such as a joint tape or joint plate or the like, is pushed through the opening 10 into the free space 8 so far that its longitudinal center line is aligned approximately with the shuttering walls 2, 3, and on the first piece of material 11th stored. Then, the second piece of material 12 is inserted so that the water barrier means 4a is received between the two pieces of material 11 and 12. The pieces of material 11 and 12 can then be suitably connected to each other, either by separately provided connecting means or, as shown, by a simple Roeble wire 13. Thus, the joint barrier 4a is securely received in the holder 4.

Fig. 3 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 100, das sich vom Ausführungsbeispiel nach den Fig. 1 und 2 nur durch eine abgewandelte Halterung 104 unterscheidet. Die Halterung 104 weist wiederum ein erstes Materialstück 111 auf, das fest mit einer der Schalungswandungen 3 verbunden, bevorzugt verschweißt ist. Das Materialstück 111 besteht aus dem gleichen Material wie im vorangegangenen Ausführungsbeispiel, enthält jedoch eine Positioniereinrichtung 114 für die Fugensperre 4a. Die Positioniereinrichtung 114 besteht im dargestellten Ausführungsbeispiel aus einer J- oder trogförmig umgebogenen Randkante des Materialstücks 111, und zwar derjenigen Randkante, die sich im Freiraum 8 befindet. Ein zweites Materialstück ist nicht vorgesehen, kann jedoch vorgesehen sein, wenn dies die Art der Fugensperre oder des zu erstellenden Bauteils erfordert. Fig. 3 shows a further embodiment of a formwork element 100 according to the invention, which differs from the embodiment according to the Fig. 1 and 2 only differs by a modified bracket 104.

The piece of material 111 consists of the same material as in the previous embodiment, but includes a positioning device 114 for the joint barrier 4a. The positioning device 114 consists in the illustrated embodiment of a J- or trough-shaped bent edge edge of the piece of material 111, namely the marginal edge, which is located in the free space 8. A second piece of material is not provided, but may be provided if this requires the type of joint seal or the component to be created.

Die Fugensperre 4a wird beim Schalungselement 100 einfach auf das Materialstück 111 gelegt und in die Positioniereinrichtung 114 eingesetzt, d.h. in die trogartige Biegung eingeschoben. Die Positioniereinrichtung 114 stellt sicher, dass die Längsmittellinie der Fugensperre 4a etwa in der Ebene zu liegen kommt, in der sich die Schalungswandungen 2, 3 befinden. Falls gewünscht oder erforderlich, kann das Fugenband 4a in geeigneter Weise am Materialstück 111 befestigt werden, beispielsweise mit Klammem oder dgl., bzw. mit Hilfe eines lose beigelegten Materialstückes 12.The joint barrier 4a is simply placed on the material piece 111 in the formwork element 100 and inserted into the positioning device 114, i. pushed into the trough-like bend. The positioning device 114 ensures that the longitudinal center line of the joint barrier 4a comes to lie approximately in the plane in which the formwork walls 2, 3 are located. If desired or necessary, the joint tape 4 a can be fastened in a suitable manner to the material piece 111, for example with clamps or the like, or with the aid of a loosely attached piece of material 12.

Fig. 4 zeigt ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 200, das sich wiederum lediglich durch die Halterung 204 für eine Fugensperre von den vorangegangenen Ausführungsbeispielen unterscheidet. Die Halterung 204 des Schalungselementes 200 enthält zwei Materialstücke 211 und 212, die wie die Materialstücke 11 und 12 ausgebildet sind, wobei jedoch sowohl das Materialstück 211 als auch das Materialstück 212 an der jeweils anliegenden Schalungswandung 2 bzw. 3 fest angeordnet, bevorzugt angeschweißt sind. Auch die Befestigung des zweiten Materialstückes 212 erfolgt wie anhand des Materialstücks 11 der Fig. 1 beschrieben. Die beiden Materialstücke 211, 212 sind so beabstandet, dass sie zwischen sich die gewünschte Fugensperre aufnehmen können. Anschließend kann die Fugensperre 4a in der Halterung 204 gehalten werden, in dem die beiden Materialstücke 211, 212 auf geeignete Weise, beispielsweise wiederum mit dem Rödeldraht 13, miteinander verbunden sind. Fig. 4 shows a further embodiment of a formwork element 200 according to the invention, which in turn differs only by the holder 204 for a joint barrier of the previous embodiments. The holder 204 of the formwork element 200 includes two pieces of material 211 and 212, which are formed as the pieces of material 11 and 12, but both the piece of material 211 and the piece of material 212 are fixedly disposed on the respectively adjacent formwork wall 2 and 3, preferably welded. The attachment of the second piece of material 212 is carried out as the basis of the material piece 11 of Fig. 1 described. The two pieces of material 211, 212 are spaced so that they can accommodate the desired joint between them. Subsequently, the Fueguard 4a are held in the holder 204, in which the two pieces of material 211, 212 are connected to each other in a suitable manner, for example, again with the tie wire 13.

Fig. 5 zeigt eine weiteres Ausführungsbeispiel eines erfindungsgemäßen Schalungselementes 300, das ähnlich dem Schalungselement gemäß Fig. 2 ausgebildet ist und sich wiederum lediglich durch eine Halterung 304 für eine Fugensperre von den vorangegangenen Ausführungsbeispielen unterscheidet. Die Halterung 304, enthält wie die Halterung 4 zwei Materialstücke 311 und 312, wobei das Materialstück 311 an der anliegenden Schalungswandung 3 fest angeordnet, bevorzugt angeschweißt ist.

Abweichend vom Ausführungsbeispiel gemäß Fig. 2 sind jedoch die Materialstücke 311, 312 gebogen bzw. gewinkelt, wobei das Materialstück 311 mit der Schalungswandung 3 einen stumpfen Winkel einschließt. Der Winkel beträgt bevorzugt zwischen 100 bis 120°, insbesondere 105 bis 115°. Das zweite Materialstück 312 ist bevorzugt in gleicher Weise gebogen oder gewinkelt, so dass die Materialstücke 311, 312 im Wesentlichen parallel zueinander verlaufen und die Fugensperre 4a zwischen sich einschließen und diese ebenfalls abwinkeln. Auf diese Weise werden Hohlräume vermieden, die sich unter der Fugensperre ausbilden könnten. Die Materialstücke 311, 312 werden bevorzugt symmetrisch gebogen oder abgewinkelt, wobei das Materialstück 311 mit dem Scheitelpunkt seiner Biegung oder Winkelung mit der Schalungswandung 3 fest verbunden ist.Notwithstanding the embodiment according to Fig. 2 However, the pieces of material 311, 312 are bent or angled, wherein the piece of material 311 forms an obtuse angle with the shuttering wall 3. The angle is preferably between 100 to 120 °, in particular 105 to 115 °. The second piece of material 312 is preferably bent or angled in the same way, so that the pieces of material 311, 312 are substantially parallel to one another and enclose the joint barrier 4a between them and likewise bend them. In this way cavities are avoided, which could form under the joint barrier. The pieces of material 311, 312 are preferably bent or angled symmetrically, wherein the piece of material 311 is firmly connected to the apex of its bending or angulation with the shuttering wall 3.
