Abstract

The shuttering is applied to a concrete connecting surface (8), which has reinforcing bars (12) which project over a supporting shuttering wall (9c). The bars are held in position against an edge (10) of the wall by an aid (1). The aid is made from shuttering material, and has openings along one side. The width of the openings corresponds to the width of the reinforcing bars, and the spacing between the openings corresponds to the required bar spacing. The aid may be placed over the bars in the manner of a comb, and may be used a sacrificial shuttering.

Description

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

Eine derartige Schalung ist beispielsweise aus dem DE-GM 92 03 275 bekannt. Die bekannte Schalung dient zur Abschalung einer Anschlußfläche zwischen einem ersten und einem zweiten Betonierabschnitt beim Betonieren einer Wand. Die Schalung enthält eine im Beton verbleibende Schalungswandung aus einer Streckmetalltafel, die zwischen die Quer- und Längsstäbe eines Gitterwerks eingeschweißt wurde. Die Schalungswandung erstreckt sich nicht über die gesamte Breite der Anschlußfläche sondern endet mit beidseitigem Abstand zur seitlichen Flächenschalung. Dieser Abstand entspricht etwa demjenigen Abstand, in dem eine Bewehrung aus einer Bewehrungsmatte zur seitlichen Flächenschalung angeordnet ist. Um die Bewehrung an Ort und Stelle festzuhalten, werden die Längsstäbe der Bewehrungsmatte in die Randbereiche der Schalungswandung eingedrückt, wo sie das Streckmetall verformen, so daß die Bewehrungsmatte in ihrer Lage zur späteren Anschlußfläche festgelegt wird. Der Abstand zwischen der Bewehrung und der seitlichen Flächenschalung wird dann durch eine herkömmliche Betondeckungsleiste überbrückt. Es hat sich jedoch herausgestellt, daß die bekannte Schalung noch verbesserungsbedürftig ist. So muß beispielsweise die Bewehrung beim Aufbau der Schalung solange festgehalten werden, bis die Betondeckungsleiste eingebaut ist.Such formwork is known for example from DE-GM 92 03 275. The known formwork is used to formwork a connection surface between a first and a second concreting section when concreting a wall. The formwork contains a formwork wall remaining in the concrete made of an expanded metal panel that was welded between the cross and longitudinal bars of a latticework. The formwork wall does not extend across the entire width of the connection surface but ends at a distance on both sides from the side surface formwork. This distance corresponds approximately to the distance in which a reinforcement from a reinforcement mat is arranged to the side surface formwork. In order to hold the reinforcement in place, the longitudinal bars of the reinforcement mat are pressed into the edge areas of the formwork wall, where they deform the expanded metal, so that the reinforcement mat is fixed in its position for the subsequent connection surface. The distance between the reinforcement and the side surface formwork is then bridged by a conventional concrete cover strip. However, it has been found that the known formwork is still in need of improvement. For example, the reinforcement when building the formwork must be held until the concrete cover strip is installed.

Aus dem DE-GM 93 01 565 ist es weiterhin bekannt, eine Schalung zum Abschalen einer Anschlußfläche zweiteilig auszubilden, um die Anordnung von Bewehrungen auch in einem größeren Abstand zu den Begrenzungskanten der Schalung, in der Mitte des Betonteils, anordnen zu können. Eine Teilung der Schalungswandung ist jedoch nicht immer möglich.From DE-GM 93 01 565 it is also known to form a formwork for shuttering a connecting surface in two parts in order to be able to arrange the arrangement of reinforcements at a greater distance from the boundary edges of the formwork, in the middle of the concrete part. A division of the formwork wall is not always possible.

Weiterhin ist aus der US-PS 3 454 255 eine kammartige Verstärkungsplatte als Bestandteil einer ansonsten aus Karton bestehenden Schalungswandung beschrieben, die nach dem Betonieren wieder entfernt werden muß. Die sich durch die Anschlußfläche erstreckenden Bewehrungsstäbe werden durch die Kartonwandung gestoßen und lediglich von der Kartonwandung in ihrer vorbestimmten Position gehalten. Die sich zwischen den kammartig vorstehenden Teilen der Verstärkungsplatte befindenden, einseitig offenen Durchbrechungen sind dagegen viel zu groß und im allseitigen Abstand zu den Bewehrungsstäben gehalten, so daß die Verstärkungsplatte nicht als Träger für die Bewehrung dienen kann.Furthermore, a comb-like reinforcing plate is described in US Pat. No. 3,454,255 as part of an otherwise made of cardboard formwork wall, which must be removed again after concreting. The reinforcing bars extending through the connection surface are pushed through the cardboard wall and are only held in their predetermined position by the cardboard wall. The openings on one side that are open between the comb-like projecting parts of the reinforcement plate are, however, much too large and are kept at all distances from the reinforcement bars, so that the reinforcement plate cannot serve as a support for the reinforcement.

Die GB-A-1 568 690 beschreibt eine Schalung aus einer Mehrzahl von Schalungsbrettern, in denen Nuten zur Aufnahme von Bewehrungen eingearbeitet sind. Nachdem Errichten der Schalung werden die Nuten durch Blätter aus flexiblem Material abgedeckt, wobei jedes Blatt ein Loch mit einem Durchmesser des entsprechenden Bewehrungsstabes und einen Schlitz enthält, der den Zugang zum Loch sichert. Die Blätter müssen dann rund um die Bewehrungsstäbe auf den Schalbrettern befestigt werden.GB-A-1 568 690 describes a formwork consisting of a plurality of formwork boards, in which grooves for incorporating reinforcements are incorporated. After the formwork has been erected, the grooves are covered by sheets of flexible material, each sheet containing a hole with a diameter of the corresponding reinforcing bar and a slot which ensures access to the hole. The sheets must then be attached to the formwork boards around the reinforcing bars.

Es sind weiterhin Schalungskästen bekannt, beispielsweise aus der DE-A-32 11 563 und der EP-A-55 321, die anstelle der Schalung verwendet werden. Die Schalungskästen haben Deckel mit seitlichen Aussparungen, durch die Bewehrungen durchgeführt werden können. Aufgrund der kastenförmigen Ausgestaltung können mit den Schalungskästen jedoch nur bügelförmige Bewehrungen festgehalten werden.Formwork boxes are also known, for example from DE-A-32 11 563 and EP-A-55 321, which are used instead of the formwork. The formwork boxes have lids with side cutouts through which reinforcements can be carried out. Due to the box-shaped design, only bow-shaped reinforcements can be held with the formwork boxes.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Schalung der genannten Art so weiterzubilden, daß auf einfache und kostengünstige Weise eine sichere Befestigung der Bewehrung auch während des Schalungsaufbaus erreicht wird.The invention is therefore based on the object of developing a formwork of the type mentioned in such a way that a secure fastening of the reinforcement is achieved even during the construction of the formwork in a simple and inexpensive manner.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved by the characterizing features of claim 1.

Die erfindungsgemäße Schalungshilfe kann in Verbindung mit jeder herkömmlichen Schalung verwendet werden, ohne daß irgendeine Änderung an der Schalung vorgenommen werden muß. Durch den zusätzlichen Einsatz der Schalungshilfe müssen keine Veränderungen mehr am Rand der Schalungswandung vorgenommen werden, um die Bewehrung befestigen zu können. Weiterhin können Schalungshilfen mit unterschiedlichen Abständen zwischen den Durchbrechungen vorrätig gehalten werden, so daß jeder Bewehrungsaufgabe, insbesondere unterschiedlichen Abständen zwischen den Bewehrungsstäben, auf einfache Weise Rechnung getragen werden kann, ohne daß Änderungen an der Schalungswandung selbst vorgenommen werden müssen. Die Bewehrung liegt vielmehr an (bei einer Betonwand) oder auf (bei einer Betonplatte) dem seitlichen bzw. oberen Rand der Schalungswandung und wird durch die Schalungswandung in nur einer Richtung unterstützt. Die Absicherung über den restlichen Umfang der Bewehrung wird durch die Schalungshilfe gewährleistet. Darüber hinaus wird durch die Schalungshilfe der Randbereich der Schalungswandung verstärkt, so daß auch bei einem höheren Druck auf die Bewehrungsstäbe sich der Abstand zwischen den Bewehrungsstäben nicht wesentlich ändert.The formwork aid according to the invention can be used in connection with any conventional formwork without having to make any changes to the formwork. The additional use of the formwork aid means that no changes need to be made at the edge of the formwork wall in order to be able to attach the reinforcement. Furthermore, formwork aids with different distances between the openings can be kept in stock, so that any reinforcement task, in particular different distances between the reinforcement bars, can be taken into account in a simple manner, without changes to the formwork wall itself having to be made. Rather, the reinforcement lies on (in the case of a concrete wall) or on (in the case of a concrete slab) the lateral or upper edge of the formwork wall and is supported in only one direction by the formwork wall. The formwork aid ensures that the rest of the reinforcement is secured. In addition, the formwork aid reinforces the edge area of the formwork wall, so that even with a higher pressure on the reinforcement bars, the distance between the reinforcement bars does not change significantly.

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

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher beschrieben. Es zeigen:

An embodiment of the invention is described below with reference to the drawings. Show it:
Fig. 1
a perspective view of an inventive formwork aid, and
Fig. 2
a section through an abge switched pad of a base plate.

Aus Fig. 1 ist in perspektivischer Darstellung eine Schalungshilfe 1 ersichtlich, die aus einer Griffleiste 2 aus Metall und einer Mehrzahl kammartig von der Griffleiste 2 abstehender Schalungsmaterialstücken 3 besteht. Die Griffleiste 2 erstreckt sich über eine Länge, die zweckmäßigerweise der Länge herkömmlicher Schalungswandungen entspricht, kann jedoch auch kürzer sein, um die Handhabung zu verbessern. Die Schalungsmaterialstücke 3 sind im wesentlichen rechteckig und mit einem eine Durchbrechung 4 bildenden Abstand zueinander angeordnet, wobei sich die Durchbrechung in gleicher Breite von den freien Kanten 3a der Schalungsmaterialstücke 3 bis zur Griffleiste 2 erstreckt.From Fig. 1, a formwork aid 1 can be seen in perspective, which consists of a handle bar 2 made of metal and a plurality of pieces of formwork material 3 protruding from the handle bar 2. The handle bar 2 extends over a length which expediently corresponds to the length of conventional formwork walls, but can also be shorter in order to improve handling. The formwork material pieces 3 are essentially rectangular and are spaced apart from one another by an opening 4, the opening extending in the same width from the free edges 3a of the formwork material pieces 3 to the grip strip 2.

Das Schalungsmaterial der Schalungsmaterialstücke 3 besteht aus einer Streckmetalltafel 5, die zwischen gitterartig angeordneten Querstäben 6 und Längsstäben 7 eingeschweißt wurde. Das Schalungsmaterial ist in der EP-PS 507 054 beschrieben, die hiermit durch Bezugnahme eingeschlossen wird. Die Quer- und Längsstäbe 6, 7 sind derart angeordnet, daß sich jeweils ein Längsstab 7 an der freien Kante 3a und jeweils einer der Querstäbe 6 an einer seitlichen Kante 3b befindet, die die Durchbrechung 4 begrenzt. Auf diese Weise wird eine allseits abgesteifte Konstruktion erreicht.The formwork material of the formwork material pieces 3 consists of an expanded metal plate 5, which was welded between cross bars 6 and longitudinal bars 7 arranged in a grid-like manner. The formwork material is described in EP-PS 507 054, which is hereby incorporated by reference. The transverse and longitudinal rods 6, 7 are arranged such that there is a longitudinal rod 7 on the free edge 3a and one of the transverse rods 6 on a lateral edge 3b, which delimits the opening 4. In this way, a stiffened construction is achieved.

Die Schalungsmaterialstücke entsprechen in ihrer Länge entlang der freien Kante 3a dem gewünschten Abstand zwischen Bewehrungsstäben. Die Breite jeder der Durchbrechungen 4 in Verlängerung der freien Kanten 3a entspricht etwa dem Durchmesser der Bwehrungsstäbe. Die Tiefe der Durchbrechungen 4, d.h. die Breite der Schalungsmaterialstücke 3 in Richtung der zweiten freien Kante 3b entspricht dem erwünschten bzw. konstruktiv möglichen Maß der Überlappung der Schalungshilfe 1 mit den Rändern einer herkömmlichen Schalung, wie dies nachfolgend beschrieben wird.The length of the formwork material pieces along the free edge 3a corresponds to the desired distance between reinforcing bars. The width of each of the openings 4 in the extension of the free edges 3a corresponds approximately to the diameter of the reinforcing bars. The depth of the openings 4, ie the width of the formwork material pieces 3 in the direction of the second free edge 3b corresponds to the desired or constructively possible degree of overlap of the formwork aid 1 with the edges of a conventional formwork, as will be described below.

Die Verwendung der erfindungsgemäßen Schalungshilfe 1 wird in Fig. 2 anhand ihrer Verwendung zum Abschalen einer Anschlußfläche 8 einer Bodenplatte beschrieben. Zu diesem Zweck wird eine herkömmliche Schalung 9 aufgebaut, die aus den beidseitigen Flächenschalungen 9a und einer Bodenschalung 9b aus herkömmlichen Schalbrettern sowie einer Schalungswandung 9c besteht, die in der Form der Anschlußfläche 8 ausgebildet ist. Die Schalungswandung 9c besteht aus dem auch für die Schalungsmaterialstücke 3 verwendeten Material, d.h. aus einer Streckmetalltafel, die zwischen die Quer- und Längsstäbe eines Gitterwerks eingeschweißt ist.The use of the formwork aid 1 according to the invention is described in FIG. 2 on the basis of its use for shuttering a connecting surface 8 of a base plate. For this purpose, a conventional formwork 9 is constructed, which consists of the two-sided surface formwork 9a and a bottom formwork 9b of conventional formwork boards and a formwork wall 9c, which is designed in the form of the connecting surface 8. The formwork wall 9c consists of the material also used for the formwork material pieces 3, i.e. from an expanded metal sheet that is welded between the cross and longitudinal bars of a latticework.

Die Breite der Schalungwandung 9c ist so bemessen, daß ihre Oberkante 10 im Abstand zur Oberkante 11 der seitlichen Flächenschalungen 9a endet. Auf die Oberkante 10 der Schalungswandung 9c wird eine Bewehrung 12 aufgelegt, die sich im wesentlichen parallel zur Bodenschalung 9b erstreckt. Die Bewehrung 12 besteht aus Längsstäben, die sich durch die Anschlußfläche 8 erstrecken und durch die obere Randkante 10 der Schalungswandung 9c im vorbestimmten Abstand zur Bodenschalung 9b gehalten. Die Bewehrung 12 wird durch jeweils eine Schalungshilfe 1 an die Randkante 10 gedrückt. Zu diesem Zweck wird die kammartige Schalungshilfe 1 von außen her über die Längsstäbe der Bewehrung 12 gesteckt und im Überlappungsbereich mit der Randkante 10 der Schalungswandung 9c verbunden, beispielsweise verrödelt. Dadurch wird die Bewehrung 12 sicher an der Randkante 10 gehalten.The width of the formwork wall 9c is such that its upper edge 10 ends at a distance from the upper edge 11 of the lateral surface formwork 9a. A reinforcement 12 is placed on the upper edge 10 of the formwork wall 9c and extends essentially parallel to the bottom formwork 9b. The reinforcement 12 consists of longitudinal bars which extend through the connecting surface 8 and are held at a predetermined distance from the floor formwork 9b by the upper edge 10 of the formwork wall 9c. The reinforcement 12 is pressed against the edge 10 by a formwork aid 1. For this purpose, the comb-like formwork aid 1 is inserted from the outside over the longitudinal bars of the reinforcement 12 and connected, for example bridged, to the edge 10 of the formwork wall 9c in the overlap area. As a result, the reinforcement 12 is held securely at the edge 10.

Der noch verbleibende Abstand zwischen der Bewehrung 12 und der Oberkante 10 der Flächenschalung 9a wird mit einer Betondeckungsleiste 13 aus Holz in üblicher Weise überbrückt. Anschließend wird der erste Betonierabschnitt 14 vergossen, wobei Schalungswandung und Schalungshilfe in die Anschlußfläche 8 eingebettet werden.The remaining distance between the reinforcement 12 and the upper edge 10 of the surface formwork 9a is bridged in the usual way with a concrete cover strip 13 made of wood. The first concreting section 14 is then poured, the formwork wall and formwork aid being embedded in the connecting surface 8.

In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann die erfindungsgemäße Schalungshilfe 1 auch zum Abschalen einer Anschlußfläche einer Wand od. dgl. verwendet werden, wobei die Schalungshilfe dabei entweder einfach über die an der Randkante der Schalungswandung anliegende Bewehrung aufgesteckt und gegebenenfalls befestigt werden muß, oder zunächst in die Durchbrechungen 4 der kammartigen Schalungshilfe eingelegt und diese dann zusammen mit der Bewehrung auf den Randbereich der Schalungswandung geschoben und dort gefestigt wird.In a modification of the described and drawn exemplary embodiment, the formwork aid 1 according to the invention can also be used to form a connection surface of a wall or the like inserted into the openings 4 of the comb-like formwork aid and this is then pushed together with the reinforcement onto the edge region of the formwork wall and is fixed there.

Die erfindungsgemäße Schalungshilfe kann auch verwendet werden, wenn anstelle von Längsstäben eine Gittermatte zur Bewehrung eingesetzt wird. Sowohl die Schalungsmaterialstücke der Schalungshilfe als auch das Schalungsmaterial der Schalungswandung kann jedes andere, herkömmliche Schalungsmaterial sein. Schließlich kann anstelle der Griffleiste ein Griffstab oder dgl. vorgesehen werden.The formwork aid according to the invention can also be used if a mesh mat is used for reinforcement instead of longitudinal bars. Both the formwork material pieces of the formwork aid and the formwork material of the formwork wall can be any other conventional formwork material.
