Bevorzugte Ausführungsform der ErfindungPreferred embodiment of the invention

Die Einrichtung zur Zerstörung monolithischer Objekte enthält ein Gehäuse 1 (Fig.1), in dem ein Kraftzylinder 2 untergebracht ist, der in Form eines Kolbens 3 und einer Kolbenstange 4 ausgebildet ist, die hin- und herbeweglich im Gehäuse 1 angeordnet sind und einen Kolbenraum 5 sowie einen Kolbenstangenraum 6 bilden. Das Gehäuse 1 ist mit Stutzen 7,8 zur Ein- bzw. Ableitung eines Arbeitsmittels versehen. Die Einrichtung weist auch eine im unteren Teil 10 des Gehäuses 1 befestigte abnehmbare Büchse 9 auf, in deren Boden 11 eine Öffnung 12 ausgeführt ist, durch die ein Distanzkeil 13 und zugeordnete spreizbare Backen 14 hindurchgehen , die in einem Bohrloch 15 eines monolithi­schen Objekts 16 untergebracht sind. Das obere Ende 17 des Distanzkeiles 13 ist mit der Kolbenstange 4 kinematisch ver­bunden. Im oberen Stirnteil 18 der spreizbaren Backen 14 sind Stützelemente 19 in Form von Hülsen vorhanden, die sich auf der Innenfläche 20 des Bodens 11 der abnehmbaren Büchse 9 abstützen. Die Stützelemente 19 in Form der Hülsen sind auf zylindrischen Ansätzen 21 des oberen Stirnteiles 18 der spreizbaren Backen 14 mit der Möglichkeit einer Schwenkung der spreizbaren Backen 14 mit deren Seitenflä­che 22 (Fig. 2) mit Hilfe von im oberen Teil der spreiz­ baren Backen 14 befestigten Handkurbeln 23 (Fig. 1) angeord­net. Die Stützelemente 19 sind mit Feststellschrauben 24 versehen, die in die Nuten 25 der zylindrischen Ansätze 21 der spreizbaren Backen 14 hineinragen. Hierbei ermöglicht die Länge der Nuten 25 eine Schwenkung der spreizbaren Bak­ken 14 mit deren Seitenfläche 22 zum Distanzkeil 13. Die Breite der Seitenfläche 22 (Fig. 2) der spreizbaren Backen 14 ist größer als die Breite der Innenfläche 26 (Fig.1) der spreizbaren Backen 14. Die Seitenfläche 22 der spreizbaren Backen 14 und deren Innenfläche 26 sind geneigt in Richtung der Schneide des Distanzkeiles 13 mit einem maximalen Querschnitt an dessen Schneide ausgeführt.The device for destroying monolithic objects contains a housing 1 (FIG. 1), in which a power cylinder 2 is accommodated, which is designed in the form of a piston 3 and a piston rod 4, which are arranged to move back and forth in the housing 1, and a piston chamber 5 and form a piston rod chamber 6. The housing 1 is provided with connecting pieces 7, 8 for the introduction or discharge of a working medium. The device also has a removable sleeve 9 fastened in the lower part 10 of the housing 1, in the bottom 11 of which an opening 12 is made, through which a spacer wedge 13 and associated expandable jaws 14 pass, which are accommodated in a borehole 15 of a monolithic object 16 are. The upper end 17 of the spacer wedge 13 is kinematically connected to the piston rod 4. In the upper end part 18 of the expandable jaws 14 there are support elements 19 in the form of sleeves which are supported on the inner surface 20 of the base 11 of the removable sleeve 9. The support elements 19 in the form of the sleeves are on cylindrical shoulders 21 of the upper end part 18 of the expandable jaws 14 with the possibility of pivoting the expandable jaws 14 with their side surface 22 (FIG. 2) with the help of the spread in the upper part Bare jaws 14 attached hand cranks 23 (Fig. 1) arranged. The support elements 19 are provided with locking screws 24 which protrude into the grooves 25 of the cylindrical lugs 21 of the expandable jaws 14. Here, the length of the grooves 25 allows the expandable jaws 14 to pivot with their side surface 22 relative to the spacer wedge 13. The width of the side surface 22 (FIG. 2) of the expandable jaws 14 is greater than the width of the inner surface 26 (FIG. 1) of the expandable jaws Jaws 14. The side surface 22 of the expandable jaws 14 and their inner surface 26 are inclined in the direction of the cutting edge of the spacer wedge 13 with a maximum cross section on its cutting edge.

Die Einrichtung arbeitet wie folgt.The setup works as follows.

In ein im monolithischen Objekt 16 (Fig. 1) vorher aus­gebohrtes Bohrloch 15 werden der Distanzkeil 13 und die spreizbaren Backen 14 mit der abnehmbaren Büchse 9 einge­setzt, wobei die schmäleren Innenflächen 26 der spreizbaren Backen 14 (Fig. 2) an den Schrägflächen des Distanzkeiles 13 anliegen. Mit Hilfe der abnehmbaren Büchse 9 wird an die spreizbaren Backen 14 das Gehäuse 1 (Fig.1) mit dem Kraft­zylinder 2 angeschlossen. Das obere Ende 17 des Keiles 13 wird in die Kolbenstange 4 gesteckt. Durch den Stutzen 7 wird in den Kolbenraum 5 des Gehäuses 1 des Kraftzylinders 2 ein Arbeitsmittel (beispielsweise Öl unter einem Druck von 100 mPa) von einer (nicht eingezeichneten) Arbeitsstation eingepreßt. Indem sich der Kolben 3 nach unten bewegt, setzt er über die Kolbenstange 4 den Distanzkeil 13 (Fig. 3) in Bewegung, der auf die Seitenflächen 22 (Fig. 4) der spreizbaren Backen 14 einwirkt und eine Spaltwirkung auf das monolithische Objekt 16 ausübt. Im monolithischen Objekt 16, beispielsweise im Stahlbeton, bildet sich ein Spalt. Das Arbeitsmittel wird durch den Stutzen 8 (Fig.1) in den Kolbenstangenraum 6 des Gehäuses 1 des Arbeitszylinders 2 geleitet. Der Kolben 3 geht in die obere Endstellung. Das Arbeitsmittel fließt aus dem Kolbenraum 5 durch den Stutzen 7 aus. Mit Hilfe der Hand­kurbeln 23 (Fig. 5, 6) werden die spreizbaren Backen 14 mit der Seitenfläche 22 zum Distanzkeil 13 verschwenkt. Hierbei drehen sich die zylindrischen Ansätze 21 der spreizbaren Backen 14 in den Stützelementen 19 (Fig. 1) um, und an die Schrägflächen des Distanzkeiles 13 kommen die Seitenflä­chen 22 der spreizbaren Backen 14 mit einer größeren Brei­te des Profil-Längschnitts zur Anlage. Der Zyklus wieder­holt sich, wozu in den Kolbenraum 5 (Fig.1) das Arbeits­mittel geleitet wird. Indem der Kolben 3 nach unten geht, setzt er über die Kolbenstange 4 den Distanzkeil 13 in Bewegung, der auf die Seitenflächen 22 (Fig. 5, 6) der spreizbaren Backen 14 einwirkt und eine Spaltwirkung auf das monolithische Objekt 16 ausübt, wodurch eine maximale Spaltbreite des monolithischen Objekts 16 erreicht und des­sen Bewehrung zu Bruch gebracht wird. Das Arbeitsmittel fließt hierbei aus dem Kolbenstangenraum 6 (Fig. 1) durch den Stutzen 8 aus.The spacer wedge 13 and the expandable jaws 14 with the removable bushing 9 are inserted into a borehole 15 previously drilled in the monolithic object 16 (FIG. 1), the narrower inner surfaces 26 of the expandable jaws 14 (FIG. 2) on the inclined surfaces of the spacer wedge 13 concerns. With the help of the removable sleeve 9, the housing 1 (FIG. 1) with the power cylinder 2 is connected to the expandable jaws 14. The upper end 17 of the wedge 13 is inserted into the piston rod 4. A working medium (for example oil under a pressure of 100 mPa) is pressed through the nozzle 7 into the piston chamber 5 of the housing 1 of the power cylinder 2 by a work station (not shown). By moving the piston 3 downward, it sets the spacer wedge 13 (FIG. 3) in motion via the piston rod 4, which acts on the side surfaces 22 (FIG. 4) of the expandable jaws 14 and exerts a splitting effect on the monolithic object 16 . A gap is formed in the monolithic object 16, for example in reinforced concrete. The working fluid is passed through the nozzle 8 (Fig.1) into the piston rod chamber 6 of the housing 1 of the working cylinder 2. The piston 3 goes into the upper end position. The working fluid flows out of the piston chamber 5 through the nozzle 7. With the help of the hand crank 23 (Fig. 5, 6), the expandable jaws 14 are pivoted with the side surface 22 to the spacer wedge 13. Here, the cylindrical lugs 21 of the expandable rotate Jaws 14 in the support elements 19 (FIG. 1), and on the inclined surfaces of the spacer wedge 13 the side faces 22 of the expandable jaws 14 come into contact with a larger width of the profile longitudinal section. The cycle repeats, for which purpose the working fluid is directed into the piston chamber 5 (FIG. 1). By moving the piston 3 downward, it sets the spacer wedge 13 in motion via the piston rod 4, which acts on the side surfaces 22 (FIGS. 5, 6) of the expandable jaws 14 and exerts a splitting action on the monolithic object 16, as a result of which a maximum Gap width of the monolithic object 16 is reached and the reinforcement is broken. The working fluid flows out of the piston rod chamber 6 (FIG. 1) through the nozzle 8.

Die Einrichtung zur Zerstörung monolithischer Objekte ermöglicht ein gefahrloses Spalten von großen Beton- und insbesondere Stahlbetonkörpern, indem die Spaltbreite zwischen dem abzuspaltenden Stück und dem Massiv vergrößert wird, wodurch sich die abzuspaltenden Stücke sicherer an­hängen lassen.The device for the destruction of monolithic objects enables safe splitting of large concrete and in particular reinforced concrete bodies by increasing the gap width between the piece to be split off and the solid, as a result of which the pieces to be split off can be attached more securely.
