Abstract

In casings whose casing wall consists of a lattice covered with plastic film, the necessary stability of the casing is currently obtained by an L-shaped bending of the edge of the casing wall pointing towards the concreting base. However, this bending requires an additional operation and also needs a relatively large amount of material. So that the casing (1) can be produced and erected in a simpler and more cost-effective manner, a U-shaped assembly supporting part (8, 9) is arranged on the concreting base (13) and is used for supporting the casing wall (2), which, with unbent bottom edges (4a, 5a, 6a, 7a) directed towards the concreting base (13), is arranged on the assembly supporting parts (8, 9). The casing is particularly suitable for producing foundations. <IMAGE>

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 aus der DE-OS 36 01 882 bekannt. Für die bekannte Schalung wird ein aus der DE-OS 31 42 148 bekanntes Material verwendet, das aus einem Gitterwerk und einer auf das Gitterwerk aufgeschrumpften Kunststoffolie besteht. Beim Aufstellen der Schalung werden plattenförmige Stücke des Materials zugeschnitten und zu einem Formhohlraum zum Formen der Betonteile zusammengestellt, durch Distanzhalter im vorgewählten Abstand gehalten und mit einer Stützkonstruktion, z.B. dem aus dem DE-GM 87 09 851 bekannten Gitterträger, zum Aufnehmen des Betondruckes versehen. Damit die Schalungswandung während des Anbringes der Distanzhalter und der Stützkonstruktion eine gewisse Standfestigkeit erhält, die ein manuelles Festhalten überflüssig macht, wird eine Kante der Schalungswandung L-förmig abgewinkelt und mit dieser Abwinklung auf die Betonierunterlage aufgestellt. Dabei kann der Schenkel entweder in das Innere des Formhohlraumes hinein oder nach außen weisen.Such formwork is known from DE-OS 36 01 882. For the known formwork, a material known from DE-OS 31 42 148 is used, which consists of a latticework and a plastic film shrunk onto the latticework. When setting up the formwork, slab-shaped pieces of material are cut to size and put together to form a mold cavity for molding the concrete parts, held at a pre-selected distance by spacers and with a supporting structure, e.g. the lattice girder known from DE-GM 87 09 851, for receiving the concrete pressure. In order for the formwork wall to have a certain stability during the attachment of the spacers and the support structure, which makes manual holding unnecessary, an edge of the formwork wall is angled in an L-shape and placed on the concrete base with this angle. The leg can either point into the interior of the mold cavity or outwards.

Das Abwinkeln der Schalungswände hat jedoch gewisse Nachteile. So stört ein Abwinkeln nach innen den Kontakt des Betons mit der Betonierunterlage, was sich insbesondere dann störend bemerkbar macht, wenn das Betonteil mit der Betonierunterlage, beispielsweise einem vorher vergossenen Betonteil, verbunden werden soll. Nach außen abgewinkelte Schalungswände liegen genau in dem Bereich, in dem die Person arbeiten muß, die die Stützkonstruktion und die Distanzhalter anbringt.Darüber hinaus erfordert das Abwinkeln einen relativ aufwendigen, zusätzlichen Arbeitsgang. Die für die Schalungswandung verwendete Platte muß darüber hinaus größer sein als eigentlich erforderlich, was sich bei dem relativ hohen Preis des Verbundmaterials verteuernd bemerkbar macht.However, bending the formwork walls has certain disadvantages. Angling inward interferes with the contact of the concrete with the concrete base, which is particularly noticeable when the concrete part is to be connected to the concrete base, for example a previously poured concrete part. Formwork walls angled outwards exactly in the area in which the person has to work, who attaches the support structure and the spacers. In addition, the angling requires a relatively complex, additional operation. The panel used for the formwork wall must also be larger than actually required, which is noticeably more expensive given the relatively high price of the composite material.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Schalung zu schaffen, die einfacher und kostengünstiger her- und aufstellbar ist.The invention is therefore based on the object of creating a formwork which is easier and less expensive to manufacture and set up.

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

Durch die erfindungsgemäße Ausgestaltung kann das für die Schalungswandung verwendete Material in ebenem, plattenförmigem Zustand verwendet werden, wobei die Schalung trotzdem eine genügend hohe Standfestigkeit beim darauffolgenden Anbringen der Distanzhalter und der Stützkonstruktion erhält. Das Material für die Schalungswandung muß nunmehr nur noch diejenige Breite aufweisen, die direkt der Höhe des Formhohlraumes entspricht. Das Montage-Unterstützungsteil ist einfach und schnell aufstellbar, gegebenenfalls wiederverwendbar und erfordert keinerlei zusätzliche Biegearbeiten an der Schalungswandung.As a result of the configuration according to the invention, the material used for the formwork wall can be used in a flat, plate-like state, the formwork nevertheless receiving a sufficiently high level of stability when the spacers and the supporting structure are subsequently attached. The material for the formwork wall now only has to have the width that corresponds directly to the height of the mold cavity. The assembly support part can be set up quickly and easily, can be reused if necessary and does not require any additional bending work on the formwork wall.

Zweckmäßigerweise wird für das Montage-Unterstützungsteil gemäß Anspruch 2 ein Streifen der auf jeder Baustelle verfügbaren Baustahlmatten verwendet.A strip of the structural steel mats available at each construction site is expediently used for the assembly support part.

Zur Erhöhung der Standfestigkeit kann die Schalungswandung gemäß Anspruch 3 mit dem Montage-Unterstützungsteil verbunden werden.To increase the stability, the Formwork wall are connected according to claim 3 with the assembly support part.

Nach Bedarf kann das Montage-Unterstützungsteil gemäß den in den Ansprüchen 4 und 5 angegebenen Alternativen entweder mit einem Steg auf der Betonierunterlage aufliegen oder die Schalungswandung von oben übergreifen.If necessary, the assembly support part according to the alternatives specified in claims 4 and 5 can either rest with a web on the concrete base or overlap the formwork wall from above.

In den Ansprüchen 6 bis 8 sind verschiedene Alternativen einer Anordnung des Montage-Unterstützungsteiles angegeben.In the claims 6 to 8 different alternatives of an arrangement of the assembly support part are given.

Durch die Ausgestaltung nach Anspruch 9 wird auf einfache Weise eine stabile Lagefixierung der Stützkonstruktion und/oder der Distanzhalter erreicht.Due to the configuration according to claim 9, a stable position fixing of the support structure and / or the spacers is achieved in a simple manner.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnungen näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Aus Fig. 1 sind die Bestandteile einer erfindungsgemäßen Schalung 1 ersichtlich. Die Schalung 1 enthält eine Schalungswandung 2, die in der Lage ist, einen Formhohlraum 3 zur Herstellung eines Betonteiles, insbesondere für ein Fundament, an zwei gegenüberliegenden Längsseiten und zwei gegenüberliegenden Stirnseiten zu umschließen. Die Schalungswandung 2 besteht aus vier Einzelteilen 4, 5, 6 und 7. Jedes der Einzelteile ist aus einem Verbundwerkstoff aus mit Kunststoffolie beschrumpftem Gitterwerk gefertigt. Als Gitterwerk wird die übliche, biegbare Baustahlmatte verwendet, die bevorzugt beidseitig mit der schrumpfbaren Kunststoffolie bedeckt ist.The components of a formwork 1 according to the invention can be seen from FIG. The formwork 1 contains one Formwork wall 2, which is able to enclose a mold cavity 3 for the production of a concrete part, in particular for a foundation, on two opposite longitudinal sides and two opposite end faces. The formwork wall 2 consists of four individual parts 4, 5, 6 and 7. Each of the individual parts is made of a composite material made of latticework shrink-wrapped with plastic film. The usual, bendable structural steel mat is used as the lattice work, which is preferably covered on both sides with the shrinkable plastic film.

Die beiden die Längsseiten des Formhohlraumes 3 bildenden Seitenwandteile 4 und 5 sind als flächige, ebene Platten ausgebildet. Die die Stirnseiten bildenden Seitenwandteile 6 und 7 bestehen aus U-förmig gebogenen Platten des obengenannten Materials, wobei die Schenkel die ebenen Seitenwandteile 4 und 5 bevorzugt auf der dem Beton zugewandten Seite überlappen.The two side wall parts 4 and 5 forming the long sides of the mold cavity 3 are designed as flat, flat plates. The side wall parts 6 and 7 forming the end faces consist of U-shaped plates of the above-mentioned material, the legs preferably overlapping the flat side wall parts 4 and 5 on the side facing the concrete.

Es sind zwei Montage-Unterstützungsteile 8 und 9 vorgesehen, die aus einem U-förmig gebogenen Streifen aus einer der üblichen Baustahlmatten bestehen. Die Stege 8a bzw. 9a weisen etwa die Breite des Formhohlraumes 3 zwischen den Seitenwandteilen 4 und 5 plus einen Zuschlag für die Wandstärkendicken der Seitenwandung auf. Die Schenkel 8b,c bzw. 9b,c sind bevorzugt ebenso lang wie die Seitenwandteile 4 und 5 breit sind.There are two assembly support parts 8 and 9 are provided, which consist of a U-shaped strip from one of the usual structural steel mats. The webs 8a and 9a have approximately the width of the mold cavity 3 between the side wall parts 4 and 5 plus an addition for the wall thickness thicknesses of the side wall. The legs 8b, c and 9b, c are preferably as long as the side wall parts 4 and 5 are wide.

Zur Aussteifung der Seitenwandung und zur Aufnahme des Betondruckes sind weiterhin Stützelemente 10 und 11 sowie Distanzhalter 12 vorgesehen. Die Stützelemente 10 und 11 sind als Gitterträger ausgebildet und weisen drei im Dreieck angeordnete, gerade Längsstäbe 10a,b,c bzw. 11a,b,c auf, wobei jeweils einer der Basisstäbe 10a,b bzw. 11a,b mit jeweils einem zickzackförmig gebogenen Stab 10d,e bzw. 11d,e mit dem Längsstab 10c, 11c am First des dreieckigen Querschnittes verbunden ist.Support elements 10 and 11 and spacers 12 are also provided for stiffening the side wall and for absorbing the concrete pressure. The support elements 10 and 11 are designed as lattice girders and have three straight longitudinal rods 10a, b, c or 11a, b, c arranged in a triangle, one of the base rods 10a, b or 11a, b each having a zigzag bent rod 10d, e or 11d, e with the longitudinal rod 10c, 11c is connected to the ridge of the triangular cross section.

Die Distanzhalter 12 bestehen üblicherweise aus einem die Breite des Formhohlraumes 3 überbrückenden Zugstab 12a und zwei Befestigungselementen 12b, 12c, die durch die Kunststoffolie an zwei sich gegenüberliegenden Stellen der Seitenwandung 2, beispielsweise die Seitenwandteile 4 und 5, gestoßen und an der Außenseite der Seitenwandung 2 befestigt werden.The spacers 12 usually consist of a tension rod 12a bridging the width of the mold cavity 3 and two fastening elements 12b, 12c, which are pushed through the plastic film at two opposite points of the side wall 2, for example the side wall parts 4 and 5, and on the outside of the side wall 2 be attached.

In den Figuren 2 und 3 ist die Schalung 1 in zusammengesetztem Zustand dargestellt. Beim Zusammensetzen werden zunächst die Montage-Unterstützungsteile 8 bzw. 9 mit ihren Stegen 8a bzw. 9a parallel und fluchtend zueinander auf eine Betonierunterlage 13 aufgesetzt, so daß die Schenkel 8b,c, 9b,c nach oben weisen. Der Abstand der beiden Montage-Unterstützungsteile 8 und 9 richtet sich nach der Größe des herzustellenden Formraumes. Die Seitenwandteile 4 bis 7 werden in der gewünschten Größe bereitgestellt bzw. gebogen und derart in den Montage-Unterstützungsteilen 8 bzw. 9 angeordnet, daß ihre freien Kanten 4a, 5a, 6a und 7a direkt, d.h. ohne Abknickung, gegen die Betonierunterlage 13 gerichtet sind. Zweckmäßigerweise werden die Überlappungen der Seitenwandteile 6 bzw. 7 mit den Seitenwandteilen 4 und 5 im Bereich der Montage-Unterstützungsteile 8 und 9 angeordnet und mit den Montage-Unterstützungsteilen verbunden. Danach können üblicherweise die Distanzhalter 12 in den einander gegenüberliegenden Seitenwandteilen 4 und 5 verankert und die Stützkonstruktion in Form der Stützelemente 10 und 11 an der Außenseite der Schalungswandung 2 angebracht werden. Aus Gründen der Übersichtlichkeit sind in den Figuren nur jeweils ein Stützelement pro Längsseite und nur eine geringe Anzahl Distanzhalter gezeichnet. Bevorzugt werden jedoch pro Längsseite zwei Stützelemente (eins oben und eins unten) und so viele Distanzhalter 12 verwendet wie erforderlich. Die Distanzhalter 12 werden in üblicher Weise durch die Kunststoffolie hindurchgestoßen und an der dem Formhohlraum 3 abgewandten Seite der Seitenwandung 2 gegen ein Zurückrutschen gesichert, wobei gleichzeitig entweder ein Gitterstab des Gitterwerkes vom Verbundmaterial und/oder ein Gitterstab des Montage-Unterstützungsteiles 8 bzw. 9 und/oder ein Gitterstab des Stützelementes 10 bzw. 11 mitumgriffen wird. Die Stützelemente 10 und 11 werden entweder an den Montage-Unterstützungsteilen und/oder am Gitterwerk des Verbundwerkstoffes befestigt. Ist die Schalung wie in den Figuren 2 und 3 gezeigt fertiggestellt, wird der Beton von oben her in den Formhohlraum 3 eingefüllt.In the figures 2 and 3, the formwork 1 is shown in the assembled state. When assembling, the assembly support parts 8 and 9 with their webs 8a and 9a are placed in parallel and in alignment with one another on a concrete base 13, so that the legs 8b, c, 9b, c point upwards. The distance between the two assembly support parts 8 and 9 depends on the size of the molding space to be produced. The side wall parts 4 to 7 are provided or bent in the desired size and arranged in the mounting support parts 8 and 9, respectively, that their free edges 4a, 5a, 6a and 7a are directed directly, ie without kinking, against the concrete base 13 . The overlaps of the side wall parts 6 and 7 with the side wall parts 4 and 5 are expediently arranged in the region of the mounting support parts 8 and 9 and connected to the mounting support parts. Thereafter, the spacers 12 can usually be anchored in the opposite side wall parts 4 and 5 and the support structure in the form of Support elements 10 and 11 are attached to the outside of the formwork wall 2. For reasons of clarity, only one support element per long side and only a small number of spacers are shown in the figures. However, two supporting elements (one at the top and one at the bottom) and as many spacers 12 as required are preferably used on each longitudinal side. The spacers 12 are pushed in the usual way through the plastic film and secured on the side of the side wall 2 facing away from the mold cavity 3 against slipping back, with either a lattice of the lattice work from the composite material and / or a lattice of the assembly support part 8 or 9 and / or a lattice bar of the support element 10 or 11 is gripped. The support elements 10 and 11 are attached either to the assembly support parts and / or to the latticework of the composite material. When the formwork has been completed as shown in FIGS. 2 and 3, the concrete is filled into the mold cavity 3 from above.

Zum Entschalen werden die Befestigungen der Distanzhalter 12 an den Gitterstäben entfernt und die vorstehenden Enden gegebenenfalls abgeschnitten. Die Stützelemente 10 und 11 werden nach dem Lösen ihrer Befestigungen entfernt und zur Wiederverwendung beiseitegelegt. Dann werden die Einzelteile 4, 5, 6 und 7 der Seitenwandung 2, eventuell nach einem leichten Aufbiegen der Schenkel 8a,c, 9b,c der Montage-Unterstützungsteile 8 und 9, vom fertigen Betonteil abgezogen und ebenfalls zur Wiederverwendung beiseitegelegt. Die Montage-Unterstützungsteile 8 und 9 können am Übergang zwischen den Schenkeln 8b,c bzw. 9b, c zum Steg 8a bzw. 9a abgeschnitten und entfernt werden.To remove formwork, the fastenings of the spacers 12 on the lattice bars are removed and the projecting ends are cut off if necessary. The support members 10 and 11 are removed after loosening their attachments and set aside for reuse. Then the individual parts 4, 5, 6 and 7 of the side wall 2, possibly after a slight bending of the legs 8a, c, 9b, c of the assembly support parts 8 and 9, are removed from the finished concrete part and also set aside for reuse. The assembly support parts 8 and 9 can be cut off and removed at the transition between the legs 8b, c or 9b, c to the web 8a or 9a.

Um das Abschneiden der Montage-Unterstützungsteile zu vermeiden, können die Montage-Unterstützungsteile gemäß Fig. 4 auch mit einem nach oben weisenden Steg 8a, 9a angeordnet sein, wobei die freien Kanten der Schenkel 8b,c, 9b,c auf der Betonierunterlage 13 aufstehen.Der weitere Aufbau der Schalung gleicht dem Ausführungsbeispiel nach den Fig. 1 bis 3, so daß auf die dortige Beschreibung verwiesen werden kann. Auch mit der Anordnung nach Fig. 4 wird die Seitenwandung der Schalung zumindest bis zum vollständigen Zusammenbau wirksam unterstützt, so daß keinerlei Abwinklungen der unteren Kanten der Seitenwandung zur Erhöhung der Standfestigkeit notwendig sind. Wie beispielsweise anhand des Schenkels 8c in Fig. 4 gezeigt, ist es in beiden Ausführungsbeispielen möglich, die Montage-Unterstützungsteile mit ihren Schenkeln an der dem Formhohlraum zugewandten, inneren Oberfläche der Seitenwandung anliegen zu lassen. Darüber hinaus ist es auch möglich, einen der Schenkel des Montage-Unterstützungsteiles an der inneren und den anderen Schenkel an der äußeren Oberfläche der Seitenwandung anliegen zu lassen. Für andere Formen der herzustellenden Betonteile können die Montage-Unterstützungsteile auch über Kreuz angeordnet werden, so daß die Seitenwandung an allen vier Seiten unterstützt wird.In order to avoid cutting off the assembly support parts, the assembly support parts according to FIG. 4 can also be arranged with a web 8a, 9a pointing upwards, the free edges of the legs 8b, c, 9b, c standing on the concrete base 13 .The further structure of the formwork is similar to the embodiment of FIGS. 1 to 3, so that reference can be made to the description there. The arrangement according to FIG. 4 also effectively supports the side wall of the formwork, at least until it is completely assembled, so that no angling of the lower edges of the side wall is necessary to increase the stability. As shown for example on the basis of the leg 8c in FIG. 4, it is possible in both exemplary embodiments to let the assembly support parts rest with their legs on the inner surface of the side wall facing the mold cavity. In addition, it is also possible to let one of the legs of the assembly support part rest on the inner and the other leg on the outer surface of the side wall. For other forms of the concrete parts to be produced, the assembly support parts can also be arranged crosswise, so that the side wall is supported on all four sides.
