Description
Einrichtung zum Einpumpen von Beton in unzugängliche Räume Zur Ermöglichung des Ausbetonierens schwer zugänglicher Hohlräume, z. B. solcher, die über oder neben eine Schalung bildenden Abschlußwänden liegen, hat man den Weg des Einstampfens des Betons verlassen und hat die Betonmasse durch Rohrleitungen in diese Hohlräume eingepreßt oder eingepumpt. Das Einpressen oder Einpumpen des Betons erforderte einen unverhältnismäßig hohen Kraftaufwand, wenn der schon eingebrachte Beton infolge seiner Steifigkeit und Zähflüssigkeit dem nachdrängenden Beton Fließwiderstände bereitete. Fernerzeigte -sich, nämlich bei" Betonbauten, die nachträglich wieder beseitigt oder freigestemmt werden mußten, daß die eisernen Bewehrungen durch die eingepreßte, von unten nach oben steigende dickflüssige Betonmasse hochgehoben und aus ihrer richtigen Lage gebracht waren.Device for pumping concrete into inaccessible rooms To enable concreting hard-to-reach cavities, e.g. B. those that are above or next to A formwork-forming end walls are, one has the way of tamping of the concrete and has the concrete mass through pipelines into these cavities pressed in or pumped in. The pressing in or pumping in of the concrete required a disproportionately high expenditure of force if the concrete already poured as a result Its stiffness and viscosity make the following concrete flow resistance prepared. It also showed itself, namely in the case of "concrete structures, which were subsequently re-established that the iron reinforcements had to be removed or chiselled free pressed in, thick concrete mass rising from bottom to top and lifted were brought out of their proper position.
Die Erfindung soll diese Schwierigkeiten überwinden, indem sie Mittel schafft, die das Einpumpen von Beton in unzugängliche Räume durch Durchbrechungen einer im wesentlichen waagerechten Schalung in schneller und zuverlässiger Weise ermöglichen.The invention is intended to overcome these difficulties by providing means creates the pumping of concrete into inaccessible spaces through openings an essentially horizontal formwork in a quick and reliable manner enable.
Die Erfindung besteht darin, daß an das Betonförderrohr ein über die Schalung senkrecht hervorstehendes Einfüllüberlaufrohr angeschlossen ist, dessen Mündung in der Nähe der oberen Begrenzung des auszufüllenden Hohlraumes liegt. In der Zeichnung stellen dar: die Abb. i Längsschnitt nach Linie A-A der Abb. 2 durch-einen von unten her verschalten Hohlraum und die Abb. 2 Querschnitt nach Linie B-B der Abb. i.The invention consists in that on the concrete delivery pipe on the Formwork vertically protruding filler overflow pipe is connected, its The mouth is located near the upper limit of the cavity to be filled. In of the drawing show: Fig. i longitudinal section along line A-A of Fig. 2 through-a from below connected cavity and Fig. 2 cross-section along line B-B of the Fig.i.
Der mit Schieber 2 versehene Rohrstutzen i ist an die Betonzuleitung F angeschlossen und mündet in das eine Öffnung der Schalung S etwa in der Mitte des auszufüllenden Hohlraumes durchsetzende Einfüllüberlaufrohr 3, das bis dicht unter die obere Begrenzung dieses Hohlraumes ragt.The pipe socket i provided with slide 2 is connected to the concrete feed line F connected and opens into one opening of the formwork S approximately in the middle the filling overflow pipe 3 penetrating the cavity to be filled, which is up tight protrudes under the upper limit of this cavity.
Die durch die Leitung F eingepreßte Betonmasse quillt über den oberen Rand des Einfüllüberlaufrohres 3 über und verteilt sich infolge des vorhandenen Gefälles sicher und schnell bis zu den äußersten Punkten des Hohlraumes.The concrete mass pressed in through the line F oozes over the upper one Edge of the filler overflow pipe 3 and distributed as a result of the existing Slope safely and quickly to the outermost points of the cavity.
In den Hohlraum ist eine Anzahl Prüf-und Anzeigerohre 4, 4' eingebaut, die durch die Schalung S hindurch nach unten führen und mit ihrem oberen Ende vorzugsweise in die vom Einfüllüberlaufrohr 3 am weitesten entfernten und höchsten Stellen ragen.A number of test and indicator tubes 4, 4 'are built into the cavity, which lead down through the formwork S and preferably with their upper end protrude into the furthest and highest points from the filler overflow pipe 3.
Fließt das Wasser aus den Standrohren 4, 4' aus, so ist daran zu ersehen, daß der Betonspiegel schon nahe an die obere Begrenzung heranreicht; es wird alsdann noch so lange Betonmasse weiter eingepreßt, bis aus allen Standrohren nicht mehr Wasser, sondern Betonmasse herausquillt. Man preßt alsdann noch weiter Betonmasse nach, bis die Förderleitung F durch Erschütterungen, die sich auch auf die Schalung übertragen, anzeigt, daß der Hohlraum ganz ,ausgefüllt ist. Der Schieber 2 wird dann geschlossen, und die Förderleitung F wird an das Einfüllüberlaufrohr des nächsten Hohlraumes angeschlossen.If the water flows out of the standpipes 4, 4 ', it can be seen that the concrete level is already close to the upper limit; it will then no more concrete mass pressed in until no more from all standpipes Water, but concrete mass oozes out. One presses then still further concrete mass after until the delivery line F caused by vibrations that are also transferred to the formwork, indicates that the cavity is completely filled. The slide 2 is then closed and the delivery line F is connected to the filling overflow pipe of the next cavity connected.
Sind über Deckenschalungen liegende Hohlräume von großen Abmessungen auszubetonieren, so werden sie zweckmäßig durch Absperrbleche 5, 5' o. dgl. in kleine Abschnitte geteilt. Nach dem Abbinden des Betons bleiben diese Absperrbleche in diesen zurück, ebenso die Einfüllüberlaufrohre 3.Are cavities of large dimensions lying above ceiling formwork to be concreted out, they are expediently broken down into small ones by means of shut-off plates 5, 5 'or the like Sections divided. After the concrete has set, these shut-off plates remain in this back, as well as the filling overflow pipes 3.
Bei dem in Abb. 2 als Ausführungsbeispiel im Querschnitt gezeigten Stollen werden zunächst zweckmäßig die schräg punktiert angedeuteten seitlichen Betonmauern auf übliche .Weise hergestellt. Erst dann wird die Betonmasse durch Einfüllüberlaufrohr 3 in den Hohlraum über der Deckenschalung S eingepreßt. Bei Versuchen wurden hierbei Drucke von etwa 3o Atmosphären, an der Förderleitung gemessen, erreicht.In the one shown in Fig. 2 as an exemplary embodiment in cross section Studs are first expediently indicated by the oblique dotted lines on the side Concrete walls made in the usual way. Only then will the concrete mass get through Filling overflow pipe 3 pressed into the cavity above the ceiling formwork S. at Tests were carried out to pressures of about 3o atmospheres, measured on the delivery line, achieved.
