Description
Es ist ein Grubenausbau aus Beton bekannt, bei welchem zwischen, die einzelnen eine größereLänge besitzenden, aus Stampfbeton hergestellten Segmente starke Einlagen aus nachgiebigem Werkstoff, insbesondere Holz eingeschaltet sind, deren Druckübertragung von der Mitte zu den Seiten, zumindest der Innenseite, abnimmt, und bei welchen die einander zugekehrten Enden der Betonsegmente oder eines derselben, zumindest auf der Innenseite, eine d en Spalt nach außen erweiternde Abschrägung oder Wölbung, großer Tiefe, z. B. je ein Fünftel der Gesamtquerschnittsbreite des Segments., besitzen ,und .der sich -dadurch kennzeichnet, daß die durch die Abschrägüng oder Wö bung der Enden der Betonsegmente gebildeten keilartigen Erweiterungen als im wesentlichen offene .Ausweichräume ausgebildet sind, in, welche im Abstand angeordnete schmale Keilkörper eingesetzt sind, welche als Träger von Versch.alungsgliederndienen. Gemäß einer besonderen Ausfüh.rungtsform dieses bekannten LAusbaus sollen in Längsrichtung der Strecke Einlagen von etwa ,der Länge der Stärke der Betonsegmente mit etwa in der Mitte liegenden Einlagen geringerer Länge, und zwar vorzugsweise in gleichmäßiger Folge abwechseln und -die Keilkörper auf den längeren Einlagen abgestützt sein. Erfindungsgemäß wird eine andere Lösung vorgeschlagen, die sich dadurch kennzeichnet, daß die keilförmigen auf der einen Seite der Fuge, vorzugsweise der Oberseite, durch Abschrägen ,des. Quetschholzes, und auf der anderen Seite, vorzugsweiGe der Unterseite, durch Abschrägen des Betonsegments gebildet werden.It is a concrete pit lining known, in which between, the individual segments that are longer and made of stamped concrete strong inserts made of flexible material, especially wood, are turned on, whose pressure transmission decreases from the center to the sides, at least on the inside, and in which the facing ends of the concrete segments or one of the same, at least on the inside, a bevel widening the gap to the outside or bulge, great depth, e.g. B. each a fifth of the total cross-sectional width of the Segments., Possess, and .der-characterized by the fact that the bevel or Wö advertising of the ends of the concrete segments formed as wedge-like extensions Essentially open .Auxiliary spaces are formed, in which spaced apart narrow wedge bodies are used, which serve as carriers of formwork members. According to a special embodiment of this known construction, in the longitudinal direction the distance deposits of about, the length of the thickness of the concrete segments with about in the middle lying deposits of shorter length, preferably in a more uniform Alternate sequence and -the wedge bodies be supported on the longer inserts. According to the invention, another solution is proposed, which is characterized by that the wedge-shaped on one side of the joint, preferably the top, through Bevelling, des. Pinch wood, and on the other side, preferably the underside, be formed by chamfering the concrete segment.
Der Erfindungsgedanke ist auch dann durchführbar, wenn .die Enden der (im übrigen nach dem Stampf-, Gieß- oder Spritzverfahren (hergestellten) Betonsegmente durch besondere, gegebenenfalls mit Eisen armierte Betonformsteine gebildet sind.The idea of the invention can also be carried out if .the ends the concrete segments (otherwise (produced) by the ramming, casting or spraying process are formed by special molded concrete blocks, possibly reinforced with iron.
In der Zeichnung ist der Gegenstand der Erfindung an einem Ausführungsbeispiel dargestellt. Fig. r ist ein Querschnitt, Fig. a zeigt im größeren Maßstab die Aus'bild u,ng der Quetschfuge.In the drawing, the subject matter of the invention is based on an exemplary embodiment shown. Fig. R is a cross-section, Fig. A shows on a larger scale the Aus'bild u, ng the pinch joint.
Hierbei bedeuten r die Betonsegmente, 2 das Quetschholz, 3a keilförmige Ausweichräume, .die durch Abschrägen des Quetschholzes erzeugt sind, 3b ke.ilförmige L,#,us-uveichräume, die durch tAbschrägen des Betonsegments entstanden sind. Selbstverständlich braucht die Abschrägung nicht geradlinig, sondern kann auch gewölbt erfolgen. Bei dem dargestellten Ausführungsbeispiel sind in die keilförmigen Ausweichräume 3a in Abständen schmale Holzkeile 4 eingesetzt, die die Verschalungsbretter 5 tragen. Für das untere Segment sind Verschalungen nicht erforderlich, so daß auch diese schmalen Holzkeile von vornherein entfallen.Here r denotes the concrete segments, 2 the squeezed wood, 3a wedge-shaped Evasive spaces, which are created by chamfering the pinch wood, 3b ke.il-shaped L, #, us-uveich rooms that were created by tapering the concrete segment. Of course the bevel does not need to be straight, but can also be curved. at the illustrated embodiment are in the wedge-shaped escape spaces 3a Narrow wooden wedges 4 are used at intervals to carry the cladding boards 5. For the lower segment cladding is not required, so that too There is no need for narrow wooden wedges from the start.
Man kann die Enden der Segmente durch besondere, gegebenenfalls mit Eisen armierte Betonformsteine ausbilden. In diesem Falle kommen auch .im oberen Teil der Fuge die schmalen Holzkeile 4 und die Verschalungsbretter 5 in Fortfall.You can use special, if necessary, the ends of the segments Form iron-reinforced concrete blocks. In this case also come in the upper Part of the joint, the narrow wooden wedges 4 and the cladding boards 5 no longer exist.
