Description
Schachtausbau. Die Erfindung betrifft einen Schachtausbau aus Schalungssteinen mit rückwärtigen Fortsätzen. Das Neue besteht darin, daB Fortsätze bis an das Gebirge herangeführt sind. Hierdurch wird verhütet, daß in der. Zwischenzeit zwischen dem Entfernen der vorläufigen Zimmerung und der Fertigstellung der Betonauskleidung das Gebirge in den Hohlraum hinter der Schalung nachfällt, was bisher oft zu lästigen Störungen und Zeitverlusten Anlaß gegeben hat.Shaft extension. The invention relates to a shaft extension made of shuttering blocks with posterior appendages. What is new is that there are extensions as far as the mountains are introduced. This prevents the. Meanwhile between the Removal of the temporary carpentry and completion of the concrete lining the mountains fall into the cavity behind the formwork, which has often been a nuisance so far Has given rise to disturbances and loss of time.
In der Zeichnung ist die Erfindung beispielsweise dargestellt, und zwar in den Abb. z und 2 in zwei Ausführungsformen der zur Herstellung des Ausbaus dienenden Formsteine; Abb.3 zeigt einen mit solchen Formsteinen hergestellten Ausbau.In the drawing, the invention is shown, for example, and although in Figs. z and 2 in two embodiments of the for the production of the expansion serving shaped bricks; Fig.3 shows an extension made with such shaped stones.
Die Schalungssteine a sind mit rückwärtigen Fortsätzen z von einer der jeweiligen Stärke des Beton- oder Eisenbetonmantels der Schachtauskleidung entsprechenden Länge versehen, so daß die Fortsätze z, wenn die Steine, wie Abb. 3 veranschaulicht, zu einer Schalung im Verband aufeinandergesetzt sind, das nach dem Abbau der Zimmerung frei liegende Gebirge völlig sicher abstützen. Hierbei bleibt der zur Aufnahme des Betons bestimmte Hohlraum frei, und die Stampf-oder Gußarbeiten können ohne Behinderung vorgenommen werden. Zur Einbringung von Eiseneinlagen können die Steine a auch im vorliegenden Falle mit senkrechten und wagerechten Aussparungen, Abb. r und 2, versehen sein.The formwork blocks a are with rear extensions z of a corresponding to the thickness of the concrete or reinforced concrete casing of the manhole lining Provided length, so that the extensions z, when the stones, as Fig. 3 illustrates, are placed on top of one another to form a formwork after the carpentry has been dismantled Support exposed mountains completely safely. Here, the one to receive the Concrete clears certain cavity, and the ramming or casting work can be done without hindrance be made. To introduce iron inlays, the stones a can also be used in present case with vertical and horizontal recesses, Fig.r and 2, provided be.
