Description
Verstellbare zweiteilige Schalungsstütze Bei Bauausführungen jeder Art sind zum Abstützen von Schalungen Schalungsstützen verschiedener Länge erforderlich. Auch müssen die Stützen, um nach Gebrauch gelöst werden zu können, auf Keile gestellt werden; dies alles erfordert viel Arbeit und Baustoff.Adjustable two-part formwork prop For construction work, everyone Art, formwork props of various lengths are required to support formwork. The supports must also be placed on wedges so that they can be loosened after use will; all of this requires a lot of work and building material.
Zwar sind verstellbare Schalungsstützen aus Eisen bekannt, bei welchen die Verstellbarkeit durch eine Schraubenspindel bewirkt wird, welche in einer Schraubenmutter, die das obere Ende einer Stützhülse darstellt, ihren Halt hat. Diese Ausführungsart erfordert viel Eisen, daher werden solche Stützen schwer und in der Ausführung teuer. Das Verstellen benötigt wegen der kleinen Ganghöhe viel Zeit, und die aufeinander reibenden Teile sind schwer zugänglich.Adjustable iron formwork props are known in which the adjustability is effected by a screw spindle, which is inserted in a screw nut, which represents the upper end of a support sleeve, has its hold. This type of execution requires a lot of iron, so such supports become heavy and expensive to make. The adjustment takes a lot of time because of the small pitch, and one on top of the other rubbing parts are difficult to access.
Nach der Erfindung wird eine billige, leicht verstellbare Schalungsstütze dadurch hergestellt, daß die Innenseiten der Stützfüße eines dreifüßigen hölzernen Gestelles mit nach einer Schraubenlinie verlaufenden Einschnitten versehen werden. In diesem Gestell ist ein Holzstempel in senkrechter Richtung beweglich. Auf dem Umfange des Stempels ist am unteren Ende ein eisernes Gewinde aufgesetzt, das etwa die Länge von zwei Gewindegängen hat. Wegen der großen Reibung von Eisen auf Holz kann die Ganghöhe verhältnismäßig groß gewählt werden, so daß Längenänderungen der Stütze schnell vorgenommen werden können. Ein weiterer Vorteil ist, daß alle reibenden Teile leicht zugänglich sind, was im Baubetrieb von besonderer Bedeutung ist. Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in Ansicht und Grundriß dargestellt.According to the invention, a cheap, easily adjustable formwork prop made by the insides of the support legs of a tripod wooden The frame can be provided with incisions running after a helical line. A wooden stamp can be moved vertically in this frame. On the The circumference of the stamp has an iron thread on the lower end, which is about the length of two threads. Because of the great friction between iron and wood the pitch can be selected to be relatively large, so that changes in length of the Prop can be made quickly. Another benefit is that it is all abrasive Parts are easily accessible, which is of particular importance in construction. on the drawing is an embodiment of the subject invention in view and floor plan shown.
Die verstellbare Schalungsstütze besteht aus zwei Teilen, dem Holzstempel a und dem Holzgerüst c. Der Stempel a trägt an einem Ende ein auf seinem Umfang aufgesetztes eisernes Gewinde b von etwa der Länge zweier Windungen. Das Gerüst c besteht aus den drei Stützfüßen cl, c2, c3; die durch Querhölzer f, g zusammengehalten werden. An der Innenseite der Stützfüße cl, c2, c3 befinden sich auf der ganzen Länge Einschnitte d, welche dem Gewinde b des Stempels a entsprechen. Wird der Stempel a in dem Gerüst c gedreht, so hebt oder senkt er sich je nach der Drehrichtung, wobei die Stütze länger oder kürzer wird. Bei richtiger Bemessung der Gewindesteigung steht die Stütze in jeder Stellung ohne besondere Feststellvorrichtung fest; dazu ist erforderlich, daß die Steigung kleiner gewählt wird als der Reibungswinkel zwischen Holz und Eisen.The adjustable formwork prop consists of two parts, the wooden stamp a and the wooden frame c. The punch a has at one end an iron thread b placed on its circumference and about the length of two turns. The frame c consists of the three support legs cl, c2, c3; which are held together by crossbars f, g. On the inside of the support feet cl, c2, c3 there are incisions d over the entire length, which correspond to the thread b of the punch a . If the punch a is rotated in the frame c, it rises or falls depending on the direction of rotation, the support becoming longer or shorter. If the thread pitch is correctly dimensioned, the support is fixed in every position without a special locking device; for this it is necessary that the slope is chosen smaller than the angle of friction between wood and iron.
