Abstract

The device is mounted on the top of a chimney (1). It consists of two parts, of which one part (3, 2) is arranged at least approximately above the other part (4, 5, 6), which can be connected to the chimney (1). A lifting mechanism (41) produces a relative movement between the two parts and at the same time results in one part being held by the other. A cabin (12, 13) held by the upper part (3) is anchored laterally on the wall of the walling (1) to be demolished at a predetermined distance L from the upper margin of the wall so that, from the cabin (12, 13), a piece of walling of length X smaller than L from the top end of the wall downwards can be demolished. The lifting mechanism (41) is then actuated in order to produce a separating movement of the lower part (4) relative to the upper part (3) and thus move the lower part (4) to a point of the walling not yet demolished, where it is fastened. Finally, the anchoring (15) of the cabin (12, 13) is released from the walling and then the lifting mechanism (41) is actuated in order to move the two parts of the device into proximity. <IMAGE>

Die an der Spitze eines Schornsteins 1 angeordnete Vorrichtung nach Fig. 1 weist an ihrer oberen Seite einen an einer Spinne 3 montierten König 2 auf. Die Spinne 3 umfasst einen Ring 8, der über ein hydraulisches Hubwerk mit einem sich unterhalb der Spinne 2 befindenden Käfig 4 verbunden ist. Am Käfig 4 sind eine Dreheinheit 5 und eine Stützeinheit 6 befestigt, die sich über mindestens drei in Fig. 1 nicht dargestellten Klemm­schuhe auf den Rand an der Spitze des Schornsteins 1 stützen kann. An der Dreheinheit 5 hängt eine Klaue 7, deren Klauen­öffnung grösser als die Wanddicke des Schornsteins 1 ist. Solche Klauen werden oft auch Zangen genannt.The device according to FIG. 1 arranged at the top of a chimney 1 has a king 2 mounted on a spider 3 on its upper side. The spider 3 comprises a ring 8, which is connected via a hydraulic lifting mechanism to a cage 4 located below the spider 2. A rotating unit 5 and a supporting unit 6 are fastened to the cage 4 and can be supported on the edge at the top of the chimney 1 via at least three clamping shoes (not shown in FIG. 1). A claw 7 hangs on the rotating unit 5, the claw opening of which is greater than the wall thickness of the chimney 1. Such claws are often called pliers.

Die Spinne 3 weist beispielsweise acht mit Schienen versehene Balken 9 auf, die seitlich, das heisst senkrecht zur Achse des Schornsteins 1 am Ring 8 aufhängbar sind. Die Balken 9 können durch Tragbalken 10 verstärkt sein. An jedem Balken 9 hängt jeweils über eine längs des Balkens horizontal verschiebbare Aufhängevorrichtung 11 eine etwa 4-förmig umgebogene ein Korb­element 13 tragende Korbstange 12, wobei acht solche Korb­elemente zwei Arten Kabinen bilden, nämlich eine obere und eine untere Kabine, die den Monteuren und anderen Spezialisten einen relativ geräumigen Arbeitsplatz bieten.The spider 3 has, for example, eight bars 9 provided with rails, which can be suspended on the ring 8 laterally, that is to say perpendicular to the axis of the chimney 1. The beams 9 can be reinforced by support beams 10. On each beam 9, a basket rod 13 carrying a basket element 13 is suspended about a 4-shaped bent basket rod 12 via a suspension device 11 which can be horizontally displaced along the beam, eight such basket elements forming two types of cabins, namely an upper and a lower cabin, which are used by the fitters and others Provide specialists with a relatively spacious workplace.

Die Stützeinheit 6, die eine durch mehrere radial angeordnete Balken verstärkte Plattform sein kann, ist mit mehren Stützen 14 versehen, auf denen die Dreheinheit 5 liegt.The support unit 6, which can be a platform reinforced by a plurality of radially arranged beams, is provided with a plurality of supports 14 on which the rotating unit 5 lies.

Die Vorrichtung nach Fig. 1 wird mit Hilfe eines Krans oder eines Helikopters in der nachstehenden Reihenfolge montiert.

  • a) Die Stützeinheit 6 wird flach auf die Spitze des Schorn­steins 1 gestellt, zentriert und gegebenenfalls mit Hilfe von bereits vorher aufgelegten Klemmschuhen fixiert.
  • b) Der Käfig 4 wird vertikal und zentriert auf die Stützein­heit 6 montiert.
  • c) Die Dreheinheit 5 wird über den Käfig 4 derart herunterge­bracht, dass eine innere Oeffnung der Dreheinheit 5 vom Käfig durchdrungen wird, bis sie die Stützen 14 der Stützein­heit 6 berührt.
  • d) Der Ring 8 der Spinne 3, der den König 2 trägt, wird auf­hängend auf den Käfig 4 montiert.
  • e) Die Balken 9 der Spinne 3 werden von oben nach unten seitlich an den Ring 8 aufgehängt.
  • f) Die Korbstangen 12 mit den Korbelementen 13 werden eine nach der anderen, vorzugsweise diagonalartig, von aussen her in die Schienen der Balken 9 eingefügt.
  • g) Die Korbelemente 13 werden untereinander rings um den Schorn­stein 1 befestigt.
1 is assembled using a crane or a helicopter in the following order.
  • a) The support unit 6 is placed flat on the top of the chimney 1, centered and, if necessary, fixed with the aid of clamping shoes which have already been placed on top.
  • b) The cage 4 is mounted vertically and centered on the support unit 6.
  • c) The rotating unit 5 is brought down over the cage 4 such that an inner opening of the rotating unit 5 from the cage is penetrated until it touches the supports 14 of the support unit 6.
  • d) The ring 8 of the spider 3, which carries the king 2, is suspended on the cage 4.
  • e) The bars 9 of the spider 3 are suspended from the side of the ring 8 from top to bottom.
  • f) The basket rods 12 with the basket elements 13 are inserted one by one, preferably diagonally, from the outside into the rails of the beams 9.
  • g) The basket elements 13 are attached to each other around the chimney 1.

Bei all diesen Operationen können die an der Aussen- oder Innen­leiter bis auf die Spitze des Schornsteins 1 hinaufgestiegenen Monteure behilflich sein.In all these operations, the fitters who have climbed the outer or inner ladder to the top of the chimney 1 can be helpful.

Die Kupplungsglieder, die zur Verbindung der Bauteile 6, 4, 5, 3 und 9 unter sich dienen, sind mit einem grosszügigen Spiel, beispielsweise konisch ausgebildet, um die Montage durch das Nacheinanderaufhängen der Bauteile mittels Kran oder Helikopter zu erleichtern.The coupling members, which serve to connect the components 6, 4, 5, 3 and 9 among themselves, are designed with a generous play, for example conical, to facilitate assembly by hanging the components one after the other by means of a crane or helicopter.

Der in Fig. 2 dargestellte Klemmschuh besteht aus einem im Querschnitt U-förmig ausgestalteten Block 21, dessen ein Schenkel ein Gewindeloch aufweist, an das ein beispielsweise mit einer Handkurbel 23 verbundener Gewindebolzen 22 anschraub­bar ist. An dem Quersteg des Blocks 21 ist eine Lagerplatte 24 beispielsweise mit Schrauben befestigt. Die Stützeinheit 6 (Fig. 2) weist eine Gewindebohrung auf, an die ein weiterer starker Gewindebolzen 25 anschraubbar ist, der ebenfalls mittels eines Kurbelrades 26 gedreht werden kann. Diese Gewindebohrung kann zweckmässigerweise in einem horizontal verschiebbaren in die Stützeinheit 6 einfügbaren Einsatzstück vorhanden sein.The clamping shoe shown in FIG. 2 consists of a block 21 with a U-shaped cross section, one leg of which has a threaded hole to which a threaded bolt 22 connected, for example, to a hand crank 23 can be screwed. On the crossbar of block 21, a bearing plate 24 is fastened, for example, with screws. The support unit 6 (FIG. 2) has a threaded hole to which a further strong threaded bolt 25 can be screwed, which can also be rotated by means of a crank wheel 26. This threaded hole can expediently be present in a horizontally displaceable insert piece which can be inserted into the support unit 6.

Der Klemmschuh nach Fig. 2 funktioniert in der Weise, dass er über die Kanten auf der Spitze des Schornsteins 1 mit der Mauer zwischen den Schenkeln des Blockes 21 gehängt und mittels der Handkurbel 23 fest angezogen wird. Dabei ist zu bemerken, dass diese vorzugsweise vier Klemmschuhe sich in anderen Radial­ebenen als die Klaue 7 befinden.2 works in such a way that it is hung over the edges on the top of the chimney 1 with the wall between the legs of the block 21 and tightened by means of the hand crank 23. It should be noted that these preferably four clamping shoes are located in different radial planes than the claw 7.

Die in Fig. 3 dargestellte Klaue besteht aus einem grossen U-förmig ausgestalteten Block 30, zwischen dessen Schenkeln die Mauer des Schornsteins stückweise zerstückelt wird, was durch zwei an den Innenseiten der Schenkel angeordnete spitzige Bolzen 31, 32 geschieht, von denen mindestens einer hydraulisch betätigt wird, um die Mauer bespielsweise durch Druck zu zer­malmen.The claw shown in Fig. 3 consists of a large U-shaped block 30, between the legs of which the wall of the chimney is broken up piece by piece, which is done by two pointed bolts 31, 32 arranged on the inside of the legs, at least one of which is hydraulic is pressed to crush the wall, for example, by pressure.

Vorzugsweise greift die Spitze des aktiven Bolzens 32 die Innenseite des Schornsteins 1 an, damit die Bruchteile durch das Kaminloch herunterfallen. Der aktive Bolzen 32 wird durch einen Mechanismus 33 hydraulisch oder gegebenenfalls mit Hilfe von Pressluft betätigt.The tip of the active bolt 32 preferably engages the inside of the chimney 1 so that the fragments fall through the chimney hole. The active bolt 32 is actuated hydraulically by a mechanism 33 or optionally with the aid of compressed air.

Die Vorrichtung nach Fig. 1 funktioniert folgendermassen.1 works as follows.

Nach dem beschriebenen Zusammenbau der Vorrichtung auf der Spitze des Schornsteins 1 werden die Korbstangen 12 mit Hilfe von Ankerbolzen 15 und dgl. an der Peripherie des Schornsteins 1 derart befestigt, dass die resultierende Verankerung das ganze Gewicht der Vorrichtung tragen kann. Erst dann kann die Klaue 7 ihre Arbeit beginnen, die darin besteht, die Wand des Schorn­steins 1 ringsum und von oben nach unten zu zersetzen. Zu diesem Zweck hängt die Klaue 7 (Fig. 1) an der Dreheinheit 5, die nach Bedarf um die Symmetrieachse des Schornsteins 1 gedreht werden kann. Zudem kann die Klaue 7 mehr oder weniger tief von der Dreheinheit 5 hängen. Da die Länge des Käfigs 4 nach Ermessen dimensioniert werden kann, ist es ohne weiteres möglich, den Schornstein 1 jeweils um 1,5 m oder eventuell mehr pro Ver­fahrensschritt zu verkürzen. Selbstverständlich können die Klemmschuhe losgelöst werden, sobald die Verankerungsoperation gelungen ist, weil dann die ganze Vorrichtung von der Ver­ankerung getragen wird.After the described assembly of the device on the top of the chimney 1, the basket rods 12 are fastened to the periphery of the chimney 1 with the aid of anchor bolts 15 and the like in such a way that the resulting anchoring can bear the entire weight of the device. Only then can the claw 7 begin its work, which consists in decomposing the wall of the chimney 1 all around and from top to bottom. For this purpose, the claw 7 (FIG. 1) hangs on the rotating unit 5, which can be rotated around the axis of symmetry of the chimney 1 as required. In addition, the claw 7 can hang more or less deeply from the rotating unit 5. Since the length of the cage 4 can be dimensioned at its discretion, it is easily possible to shorten the chimney 1 by 1.5 m or possibly more per process step. Of course, the clamping shoes can be released as soon as the anchoring operation is successful, because then the entire device is carried by the anchoring.

Nachdem die Spitze des Schornsteins um eine bestimmte Länge, beispielsweise 1,5 m verkürzt wurde, wird ein hydraulisches Hubwerk 41 im Käfig 4 betätigt, um den Käfig mit der Drehein­heit 5 und der Stützeinheit 6 relativ zur Spinne nach unten zu bewegen. Somit wird wiederum die Stützeinheit 6 mit Hilfe der Klemmschuhe (Fig. 2) auf den Stumpf des Schornsteins fixiert, wobei die Klemmschuhe die Unebenheiten des Stumpf­randes ausgleichen können. Da nun die Vorrichtung wieder über die Stützeinheit 6 mit dem Schornstein 1 verbunden ist, können die Verankerungen 15 losgelöst werden, so dass die Kabinen frei hängend nur von den Balken 9 getragen werden. In diesem Moment wird das Hubwerk wieder betätigt, um die Spinne 3 relativ zum Käfig 4 nach unten zu bewegen, bis der Ring 3 wieder in seiner Position in der Nähe des Käfigs 4 ist. Damit sind die Kabinen auch ein Stück weiter heruntergekommen, wo sie nochmals an der Schornsteinmauer verankert werden. Das Verfahren kann so oft wiederholt werden, bis der Schornstein in seiner ganzen Höhe demoliert ist.After the top of the chimney has been shortened by a certain length, for example 1.5 m, a hydraulic lifting mechanism 41 in the cage 4 is actuated in order to move the cage with the rotating unit 5 and the supporting unit 6 downwards relative to the spider. Thus, the support unit 6 is in turn fixed on the stump of the chimney with the aid of the clamping shoes (FIG. 2), the clamping shoes being able to compensate for the unevenness of the stump edge. Since the device is now connected to the chimney 1 again via the support unit 6, the anchors 15 can be detached, so that the cabins are suspended only by the beams 9. At this moment the hoist is operated again to move the spider 3 downwards relative to the cage 4 until the ring 3 is again in its position near the cage 4. The cabins have now come down a little further, where they are anchored to the chimney wall. The process can be repeated until the chimney is completely destroyed.

Für die Montage der Kabinen ist der Einsatz eines Krans oder eines Helikopters nicht notwendig, wenn sie ganz unten zusammen­gebaut und mit Hilfe beispielsweise eines auf der Spinne 3 montierten Flaschenzugs hinaufgezogen werden.It is not necessary to use a crane or a helicopter to assemble the cabins if they are assembled at the bottom and pulled up using, for example, a pulley mounted on the spider 3.

Anstelle des hydraulischen Hubwerks kann ebenfalls ein Ver­schiebungsmechanismus eingesetzt werden, der eine relative Be­wegung zwischen der Spinne 3 und dem Käfig 4 um einen Betrag L erlaubt, derart, dass die starke Verbindung zwischen den beiden Teilen 3 und 4 beibehalten wird.Instead of the hydraulic lifting mechanism, a displacement mechanism can also be used, which allows a relative movement between the spider 3 and the cage 4 by an amount L. allowed such that the strong connection between the two parts 3 and 4 is maintained.

Die Klaue 7 ist nicht notwendig, falls man es vorzieht mit Abbauhämmern zu arbeiten. Insbesondere wäre die Verwendung von Abbauhämmern oder dgl. zwingend, wenn es sich um die Demolierung eines hohen Mauerwerkes handelt, was auch nach dem Verfahren gemäss der beiliegenden Erfindung möglich ist, wobei dann nicht ringförmig, sondern länglich ausgestaltete Kabinen vorgesehen werden müssten. In einem solchen Fall müsste der Verschiebungsmechanismus eine relative Bewegung von oben nach unten und von rechts nach links und umgekehrt machen können.The claw 7 is not necessary if you prefer to work with breakers. In particular, the use of demolition hammers or the like would be mandatory if it is a question of demolishing high masonry, which is also possible according to the method according to the enclosed invention, in which case it would be necessary to provide elongated cabins rather than rings. In such a case, the displacement mechanism should be able to make a relative movement from top to bottom and from right to left and vice versa.

Solche Abbauhämmer können beispielsweise mit hydraulischem Oel oder Pressluft arbeiten. Anstelle der Klaue oder Zange 7 kann auch eine Fräsvorrichtung oder gegebenenfalls ein Brenner verwendet werden, weil der Schornstein nicht nur aus Backstein sondern auch aus Beton oder Metall bestehen kann. Die Kabine 12, 13 kann mehr oder weniger an eine runde, hexa­gonale oder polygonale Form des Kamins angepasst sein.Such breakers can work with hydraulic oil or compressed air, for example. Instead of the claw or pliers 7, a milling device or possibly a burner can also be used because the chimney can consist not only of brick but also of concrete or metal. The cabin 12, 13 can be more or less adapted to a round, hexagonal or polygonal shape of the fireplace.
