Definitions

  • the present invention relates to a method and a device for the demolition of tall, at least partially free-standing masonry.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the anchors 15 can be detached, so that the cabins are suspended only by the beams 9.
  • 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.
  • 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.
  • the claw 7 is not necessary if you prefer to work with breakers.
  • 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.
  • the displacement mechanism should be able to make a relative movement from top to bottom and from right to left and vice versa.
  • breakers can work with hydraulic oil or compressed air, for example.
  • 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.
