Description

Die Erfindung bezieht sich auf eine Halterung für Stellbretter für die Schüttung von Beton für Decken an Bauten.The invention relates to a holder for adjusting boards for the pouring of concrete for ceilings in buildings.

Bei der Herstellung von Böden oder Decken aus Beton wird nach Erstellung der senkrechten z. B. aus einem Mauerwerk bestehenden Wand eine waagerechte Schalung aus Holzbrettern verwendet, auf welche nach Einbringen von Bewehrungen der Beton geschüttet wird. Vor dem Aufschütten werden an den senkrechten Wänden sog. Stellbretter aufgesetzt, um als seitliche Begrenzung für die Betondecke zu dienen. Das Stellbrett muß in seiner Lage und in seiner senkrechten Stellung genau angeordnet sein. Zum Befestigen wurden bisher Drahtstücke verwendet, welche oben und unten an dem Stellbrett durch ein Loch hindurchgeführt und dann z. B. an der Bewehrung der herzustellenden Decke oder des Bodens befestigt werden. Für das Festlegen des Stellbrettes in der gewünschten Lage ist es erforderlich, eine Mehrzahl solcher Drahtstücke längs der Länge des Stellbrettes vorzusehen ; der Abstand der einzelnen Drahtstücke hängt von der Höhe der aufzuschüttenden Betonmasse und von der Länge der Decke, des Bodens od. dgl. ab. Dann wird der Beton bis zu einer gewünschten Höhe aufgegossen und aufgeschüttet, anschließend wird der Haltedraht durchgetrennt und das Stellbrett entfernt. Das Stellbrett dient zum einen als Begrenzung für den geschütteten Beton, es kann jedoch auch als ein späteres Bauelement im Bauwerk verbleiben, nämlich wenn es aus einem wärme- oder schalldämmenden Material hergestellt worden ist. Hierzu bietet sich ein Stellbrett aus Holzfasern oder Holzspänen in Zement an ; derartiges Material ist in Plattenform auf dem Markt erhältlich. Die bisher verwendeten Befestigungsmittel für Stellbretter haben jedoch den späteren Verbleib eines schalldämmenden Stellbrettes im Bauwerk ausgeschlossen.In the manufacture of floors or ceilings made of concrete, after creating the vertical z. B. from a masonry wall used a horizontal formwork of wooden boards, on which the concrete is poured after reinforcement. Before filling, so-called adjusting boards are placed on the vertical walls to serve as a lateral boundary for the concrete ceiling. The positioning board must be positioned precisely in its position and in its vertical position. To fasten wire pieces were previously used, which passed through a hole at the top and bottom of the control board and then z. B. attached to the reinforcement of the ceiling or floor to be manufactured. To set the positioning board in the desired position, it is necessary to provide a plurality of such pieces of wire along the length of the positioning board; the distance between the individual pieces of wire depends on the height of the concrete mass to be poured on and on the length of the ceiling, floor or the like. Then the concrete is poured and poured up to a desired height, then the holding wire is cut through and the setting board is removed. The setting board serves on the one hand as a boundary for the poured concrete, but it can also remain as a later component in the building, namely if it has been produced from a heat or sound-insulating material. A positioning board made of wood fibers or wood chips in cement is ideal for this; such material is available on the market in sheet form. The previously used fasteners for adjusting boards have ruled out the later remaining of a sound-absorbing adjusting board in the building.

In der Praxis hat es sich als nachteilig und zeitraubend erwiesen, für Stellbretter an Ort und Stelle die Drahtstücke anzubringen und festzulegen. Außerdem ist es nachteilig, daß für das Hindurchführen der Drahtstücke im oberen und unteren Teil eines solchen Stellbrettes Löcher hergestellt werden müssen.In practice, it has proven to be disadvantageous and time-consuming to attach and fix the wire pieces in place for adjusting boards. In addition, it is disadvantageous that holes must be made in the upper and lower part of such an adjusting board for the passage of the wire pieces.

Durch die DE-A-2 912 122 ist eine Halterung für Stellbretter für die Schüttung von Beton für Decken an Bauten, die aus zwei das Stellbrett oben und unten teilweise umgreifenden Klammern besteht, die ihrerseits an zwei an der unteren Deckenschalung zu befestigenden Schenkeln ausgebildet sind, bekannt. Es handelt sich hierbei um eine verhältnismäßig kompliziert herzustellende Konstruktion.DE-A-2 912 122 is a holder for adjusting boards for the pouring of concrete for ceilings in buildings, which consists of two brackets partially encompassing the adjusting board above and below, which in turn are formed on two legs to be fastened to the lower ceiling formwork , known. It is a relatively complicated construction to manufacture.

Zweck der Erfindung ist daher, einfacher zu erstellende Halterungen für die Stellbretter bei der Herstellung von Decken, Böden od. dgl. aus Beton zu schaffen, die vorgefertigt werden können, einfach eingesetzt werden können und dennoch an unterschiedlich dicke Stellbretter angepaßt werden können.The purpose of the invention is therefore to provide easier-to-create brackets for the adjusting boards in the manufacture of ceilings, floors or the like from concrete, which can be prefabricated, can be used easily and can nevertheless be adapted to adjusting boards of different thicknesses.

Gemäß der Erfindung werden diese Probleme gelöst durch Halterungen nach den beigefügten Ansprüchen. Wesentlich für die Halterung gemäß der Erfindung ist, daß sie aus zwei Teilen aus Blattmetall hergestellt wird und daß diese Teile für sich oder zusammen an einem Schalbrett befestigt werden können. Durch die Befestigung der Einzelelemente aneinander kann eine Anpassung an verschieden hohe und verschieden dicke Stellbretter ermöglicht werden.According to the invention, these problems are solved by brackets according to the appended claims. It is essential for the holder according to the invention that it is made of two parts made of sheet metal and that these parts can be attached to a formwork board alone or together. By attaching the individual elements to one another, adaptation to different height and thickness boards can be made possible.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is shown for example.

  • Figur 1 zeigt eine Querschnittsansicht der Halterung gemäß der Erfindung.Figure 1 shows a cross-sectional view of the holder according to the invention.
  • Figur 2 zeigt einen senkrechten Schnitt durch einen Teil eines Mauerwerks, einer Betondecke mit Schalung und mit der Halterung gemäß der Erfindung an Ort und Stelle.Figure 2 shows a vertical section through part of a brickwork, a concrete ceiling with formwork and with the bracket according to the invention in place.

Gemäß Fig. 1 weist die Halterung einen mit 3 bezeichneten Unterschenkel auf, der an seinem einen Ende einen unteren Klammerteil 4 trägt. Im Abstand von dem unteren Klammerteil 4 ist an dem Unterschenkel 3 ein mit 5 bezeichneter Vorsprung durch einen Biegevorgang ausgebildet, so daß zwischen Klammerteil 4 und Vorsprung 5 sich ein Zwischenraum von ca. 5 cm befindet. Am hinteren Ende des Unterschenkels 3 befinden sich mehrere Löcher 3a.1, the holder has a lower leg denoted by 3, which carries a lower bracket part 4 at one end. At a distance from the lower clamp part 4, a projection 5 is formed on the lower leg 3 by a bending process, so that there is an interspace of approximately 5 cm between the clamp part 4 and the projection 5. At the rear end of the lower leg 3 there are several holes 3a.

Ein Oberschenkel 6 erstreckt sich nach oben und schräg nach vorn vom Unterschenkel 3, der an seinem vorderen Ende zu einem oberen Klammerteil 7 gebogen ist. Im Abstand von ca. 5 cm zum Klammerteil 7 befindet sich ein Knickteil 7a. Der Unterschenkel 3 ist nach hinten verlängert und weist nahe seinem hinteren Ende zwei mit 8 bezeichnete Löcher auf, durch welche z. B. ein Nagel zum Festlegen der beiden Schenkel 3 und 6 an einer Schal-ungswand 11 hindurchgeschlagen werden kann. Zwischen dem Unterschenkel 3, nämlich zwischen den Teilen 4 und 5 und dem Oberschenkel 6, nämlich den Teilen 7 und 7a, befindet sich ein Stellbrett 9a. Das Stellbrett hat eine Dicke, die dem Abstand zwischen den einzelnen Klemmteilen 4, 5 und 7, 7a entspricht. Damit das auf diese Art und Weise eingeklemmte Stellbrett 9a in seiner Lage festgelegt werden kann, befindet sich im oberen Klemmbereich des Oberschenkels 6 ein Durchgangsloch 6a, und mit Hilfe eines Nagels, der von oben her durch dieses Loch 6a hindurchgeschlagen wird, kann das Stellbrett 9a in seiner Stellung und Lage festgelegt werden.A thigh 6 extends upward and obliquely forward from the lower leg 3, which is bent at its front end to an upper bracket part 7. There is a bent part 7a at a distance of about 5 cm from the clamp part 7. The lower leg 3 is extended to the rear and has near its rear end two holes labeled 8 through which z. B. a nail for fixing the two legs 3 and 6 can be knocked through on a formwork wall 11. Between the lower leg 3, namely between the parts 4 and 5 and the thigh 6, namely the parts 7 and 7a, there is an adjusting board 9a. The setting board has a thickness that corresponds to the distance between the individual clamping parts 4, 5 and 7, 7a. So that the positioning board 9a clamped in this way can be fixed in its position, there is a through hole 6a in the upper clamping area of the thigh 6, and with the help of a nail which is pushed through this hole 6a from above, the setting board 9a be determined in its position and location.

Zur Veranschaulichung der Größenordnung sei erwähnt, daß das Stellbrett 9a eine Breite von ungefähr 5 cm hat.To illustrate the order of magnitude, it should be mentioned that the setting board 9a has a width of approximately 5 cm.

In Fig. 1 sind der Ober- und der Unterschenkel der Halterung nicht in ihrer vollen Länge wiedergegeben, zwischen dem vorderen (linken) und dem hinteren (rechten) Ende dieser Teile befinden sich durch Wellenlinien angedeutet Schnittstellen.In Fig. 1, the upper and lower legs of the bracket are not shown in their full length, between the front (left) and the rear (right) end of these parts there are interfaces indicated by wavy lines.

Wesentlich ist für die Verbindung der Schenkel 3 und 6, daß diese in einer unterschiedlichen Lage zueinander befestigt werden können, indem eines der Löcher 8 mit irgendeinem anderen der Löcher 3a in Übereinstimmung gebracht wird und die beiden Schenkel mit Hilfe eines Nagels 12 (Fig. 2) an einer Schalung 11 befestigt werden. Beide Schenkel bestehen aus einem verbiegbaren Material, und insbesondere durch Verbiegen des Oberschenkels 6 kann eine Anpassung auf unterschiedlich hohe Stellbretter 9a erreicht werden.It is essential for the connection of the legs 3 and 6 that these can be fastened in a different position to one another by bringing one of the holes 8 into line with any other of the holes 3a and the two legs being fastened to a formwork 11 with the aid of a nail 12 (FIG. 2) . Both legs are made of a bendable material, and in particular by bending the thigh 6, an adjustment to adjusting boards 9a of different heights can be achieved.

Nachstehend wird die Art und Weise der Anbringung der Schenkel 3 und 6 in Verbindung mit einem Teil eines Bauwerks gemäß Fig. 2 erläutert. Mit 10 ist ein Mauerwerk bezeichnet, in dessen oberem Ende die Schalung 11 angeordnet ist, es kann sich hierbei um einzelne Holzbretter handeln. An das Mauerwerk 10 schließt sich das mit 9b bezeichnete Stellbrett an, das oben und unten von den Klammerteilen 7, 7a und 4, 5 umgriffen wird. Da das Stellbrett 9b dünner ist als der Abstand zwischen jenen Klemmteilen, können die vorderen Teile, nämlich die Klammerteile 7 und 4 etwas eingeschlagen werden, so daß durch Verbiegen dieser Teile ein fester Halt für das Stellbrett 9b erreicht wird. An dieser Stelle sei erwähnt, daß ein Stellbrett etwa im Abstand von 1 m eine Halterung gemäß der Erfindung benötigt, die Schenkel selbst haben eine Breite von einigen Zentimetern, vorzugsweise 2,5 cm.The manner in which the legs 3 and 6 are attached in connection with part of a building according to FIG. 2 is explained below. With 10 is a masonry designated, in the upper end of which the formwork 11 is arranged, it can be individual wooden boards. Adjoining the masonry 10 is the adjusting board designated 9b, which is gripped at the top and bottom by the clamp parts 7, 7a and 4, 5. Since the setting board 9b is thinner than the distance between those clamping parts, the front parts, namely the clip parts 7 and 4 can be turned in a little so that a firm hold for the setting board 9b is achieved by bending these parts. At this point it should be mentioned that a positioning board needs a holder according to the invention at a distance of approximately 1 m, the legs themselves have a width of a few centimeters, preferably 2.5 cm.

Zunächst wird der Unterschenkel 3 in die gewünschte Lage gebracht, sodann wird der Oberschenkel 6 auf das Stellbrett 9b aufgelegt, wobei die Vorsprünge 4 und 7 entweder jetzt eingebogen werden oder bereits vorher eingebogen worden sind. Sodann wird von oben her der Nagel 12 durch zwei übereinstimmende Löcher 8 und 3a in den Schenkeln in die Verschalung 11 eingeschlagen. In der Fig. 2 ist mit 12a der Kopf eines Nagels oder eines anderen Befestigungsmittels gezeigt. Nachdem das Stellbrett in der beschriebenen Art und Weise festgelegt worden ist, kann der Beton geschüttet werden, er nimmt nach Aushärtung die mit 14 bezeichnete Form einer Decke an.First, the lower leg 3 is brought into the desired position, then the upper leg 6 is placed on the setting board 9b, the projections 4 and 7 either being bent in now or having been bent in before. Then the nail 12 is hammered into the casing 11 from above through two matching holes 8 and 3a in the legs. 2, the head of a nail or other fastening means is shown at 12a. After the setting board has been fixed in the manner described, the concrete can be poured, after hardening it takes on the shape of a ceiling, designated 14.

Es besteht nun die Möglichkeit, das Stellbrett 9b zu entfernen, indem der Oberschenkel 6 nach oben gebogen wird. Der Oberschenkel 6 kann auch durch Hin- und Herbiegen so abgebrochen werden, daß er aus der Decke 14 nicht nach oben vorsteht. Es besteht jedoch auch die Möglichkeit, das Stellbrett 9b im Bauwerk zu belassen, beispielsweise wenn vor das Mauerwerk 10 und vor das Stellbrett 9b eine Verklinkerung gesetzt wird. Der vorstehende Teil des Oberschenkels 6 ist dabei deshalb nicht störend, da er sich an einer Stelle befindet, wo späterhin das Mauerwerk für das nächste Geschoß erstellt werden soll.It is now possible to remove the setting board 9b by bending the thigh 6 upwards. The thigh 6 can also be broken off by bending back and forth in such a way that it does not protrude from the ceiling 14 upwards. However, there is also the possibility of leaving the adjusting board 9b in the building, for example if a brick is placed in front of the masonry 10 and in front of the adjusting board 9b. The protruding part of the thigh 6 is therefore not disturbing, since it is located at a point where the masonry for the next floor will be created later.
