Definitions

  • This invention relates to improvements in the piecemeal demolition of chimneys made of concrete, brick, steel, etc. ,
  • An object of the present invention is to obviate or mitigate the above disadvantages.
  • a rig for use in the piecemeal demolition of chimneys comprising a spider having a plurality of radiating arms, a jack mounted on each arm and adjustable therealong and having a supporting foot under the arm, and a substantially annular platform underslung from the spider.
  • a method of piecemeal demolition of chimneys comprising the steps of either erecting or placing on the top of a chimney the above rig with the spider supported, via the jacks, on the rim of the chimney and with the substantially annular platform adjacent either the outside or the inside of the wall of the chimney, removing the fabric of the chimney from under the feet of alternate ones of the jacks so as to form a castellated upper edge of the chimney, lowering the feet of the alternate jacks into supporting contact with the newly presented surfaces thereunder, removing the fabric of the chimney from under the feet of the intermediate ones of the jacks, lowering the feet of the intermediate jacks into supporting contact with the newly presented surface thereunder, and repeating the steps of removing the fabric of the chimney and lowering the feet of the jacks.
  • a chimney 1 is surmounted by a rig comprising a spider having twelve radiating arms 2 interconnected at their outer ends, and each in the form of an zaluminium lattice-work box beam.
  • the arms 2 support at their outer ends twelve modular arch members 3, each module being also in the form an aluminium lattice-work box beam, the arch members 3 forming a framework of a dome or igloo-type of structure.
  • Each arm 2 has a hydraulic jack 4 adjustable therealong with a supporting foot 5 in contact with the rim of the chimney.
  • Underslung from the arms 2 via substructures 6 at the outer ends of the arms is a substantially annular sectional platform 7, the sections of which are designed to surround and be contiguous with the outside of the chimney wall.
  • the sections of the platform 7 are slidable within the substructures 6 to accomodate the taper in the outside of the chimney wall.
  • an adjustable barrier or membrane 8 is underslung from the arms 2 via substructures 9.
  • Flexible edge seals may be provided for the sections of the platform 7 and the barrier or membrane 8 to contact the outside and inside of the chimney wall.
  • Communication between the platform 7 and the ground is by means of a cage 10 which can run up and down a modular lattice-work mast 11 secured to the outside of the chimney wall by outriggers 12.
  • the cage 10 may be driven up and down the mast 1 I by a rack-and-pinion system.
  • the rig is covered by a tough flexible plastics cover (not shown) which extends down to the platform 7, handraild being provided within the cover for the safety of personnel.
  • the rig may be either erected or placed substantially as a whole on the rim of a chimney by using a helicopter or a hoist mounted on top of the chimney to lift either parts or the whole of the rig as appropriate.
  • the operatives work from the platform 7 and remove the fabric of the chimney from under the feet 5 of alternate ones of the jacks 4 so as to form a castellated upper edge of the chimney. Then the feet 5 of the alternate jacks 4 are lowered into supporting contact with the newly presented surfaces thereunder and the fabric of the chimney is removed from under the feet 5 of the intermediate jacks 4 and these feet 5 are lowered into supporting contact with the newly presented surface thereunder.
  • the taper of the chimney is accomodated by adjustment of the jacks 4 along the arms 2, adjustment of the sections of the platform 7 and adjustment of the barrier or membrane 8.
  • the removed fabric of the chimney is prevented from falling into the chimney by the barrier or membrane 8 and is disposed of via the cage 10.
  • Some chimneys have stainless steel liners spaced inwardly from the inside of the chimney proper.
  • an annular platform is underslung from the arms of the spider via substructures inboard from the outer-ends of the arms to enter such space, steps being provided leading to the underslung platform from an upper and outer annular' platform on the outer ends of the arms of the spider and extending beyond the edge of the chimney so that a hoist arrangement can be fitted in a similar manner to that shown in the drawing.
  • a source of power supply and facilities are provided within the covered rig to maintain controlled working conditions and afford service and messing facilities for the operatives.
  • Service tappings are available at suitable voltage from the power supply for tools, general illumination and aircraft warning lights mounted atop the rig, thus allowing the main chimney lights to be removed from the chimney prior to commencement of demolition.
  • the rig thus enables demolition work to be continued irrespective of weather conditions.
  • wire ropes may be provided from the rig to the ground and be adjustably tensioned from the rig.
