Definitions

  • the present invention concerns improvements for an elevation jig for buildings or other heavy objects or constructions.
  • an elevation jig to be used for restoring buildings.
  • Such an elevation jig comprises square hollow profiles which telescopically may be placed outside each other and which may be locked in a selected position by the use of locking bolts fitting into the reciprocally cooperating holes in the hollow profiles.
  • To the hollow profiles it is assigned one or more platforms which may be locked in a wanted elevation and on said platforms there may be placed jacks for elevating parts or the relevant building after the relevant building part has been secured to the jack(s).
  • Said elevation jig system has, however, certain weaknesses and drawbacks which it is suitable to improve.
  • the elevation jig that may be moved.
  • a transporting and rotating system to be used with said elevation jig wherein the rotation system itself may be placed either on any location inside the scaffold structure inside the elevation jig or as a substructure for the scaffold structure in such a way that on this substructure there may be mounted wheels for transporting the elevation jig and optionally the object or construction to which the elevation jig is secured.
  • the present invention encompasses a scaffold for an elevation jig 1 comprising pipes 2 with a number of holes 3 for bolts.
  • the pipes 2 may have any cross sectional shape, but it is preferred that the cross section is square since this prevents the pipes to twist inside the scaffolding.
  • the pipes 2 are telescoping i.e. they have different cross sectional areas so that the pipes fit outside each other. The reciprocating locking between the pipes may be accomplished with bolts fitting inside the holes 3 (not shown). If the pipes 2 have a round cross section a reciprocating twisting action between these may be prevented by there being placed bolts through the holes 3.
  • the scaffolding pipes 2 are located in a metal foot 4 carrying the weight of the scaffolding 1.
  • the locking of the scaffolding pipe 2 inside the foot 4 may be carried out either by the cross section of the pipes being edged (e.g. square) or by there being used bolts being locked through the holes 3. In such an occasion the foot 4 will also have to include corresponding locking holes.
  • the foot 4 rests at its bottom on a pivoting plate 5.
  • This pivoting plate 5 may be operated/pivoted in any way, e.g. by the aid of pivoting arms 6 or through an electric motor 7 that acts on the pivoting plate 5 (see fig. 3 ). By using an electric motor 7 the pivoting action may be accomplished through a worm gear 8 which optionally may function via the motor 7 on the pivoting plate 5.
  • the movement of the pivoting arms 6 may be guided by a hydraulic or pneumatic piston 9 being secured to the base 4 and to an arm 10 running between the other end of the piston 9 and the pivoting arm 6.
  • the piston 9 By operating the piston 9 the arm 10 may be act to adjust the rotation angle between the arm 6 and the base 4.
  • the pivoting plate is secured to a chassis 11 which again is coupled to one or more wheels 12.
  • hydraulic, pneumatic or mechanical lifting devices e.g. jacks or hydraulic pistons
  • the pipes 2 of the elevation jig may be lifted without any tilting. This is especially important if it is relevant to elevate/jack up high constructions such as high buildings where it is important to avoid any tilting in the system.
  • FIG. 2 An internal lifting system running from the pivotable bottom frame according to the invention, is shown I fig. 2 .
  • an internal lifting pole 13 is secured to an internal hydraulic pump 14 in the base 11 of the chassis according to the invention.
  • This internal lifting pole 13 is secured to the base 11, and the pipe 2 in the elevation jig is placed outside of this lifting pole 13.
  • FIG. 4 An alternative to the internal elevation system disclosed supra is shown in figs. 4 and 5 .
  • the elevation device (the hydraulic piston) 14 is located between two telescoping pillars 17 bracing the elevation system.
  • the elevation pipes 2 in the elevation jig will with such an elevation system preferably be located in the centre of the lifting system so that the action point of the forces will lie along a straight line through the symmetrical axis of the system.
  • Such an elevation system may be placed at any suitable location in the elevation jig, and may also be located on the pivotable chassis according to the invention.
  • FIG. 5 An alternative elevation system also comprising an open lifting device (hydraulic/pneumatic/mechanical pump/jack) is shown in fig. 5 .
  • the elevation device 14 is shown located between two pipe poles 2,2' and being coupled to these pipe poles via two intermediate sections 18,18'.
  • the intermediate sections 18,18' and the pipe poles 2,2' may be secured to each other through the aid of reciprocally acting securing holes 3 and securing bolts.
  • Such an elevation system being shown in fig. 5 may be used on any site in the elevation jig, but may also be coupled to the pivotable chassis according to the invention.
  • Such a securing bolt 19 will include a pipe 20 with internal threads.
  • the pipe 20 has in each of its outer ends a recessed flange 21 being deep enough to harbour the head of an umbraco screw 22.
  • the thread part of the umbraco screws 22 will fit inside the internal threads in the pipes 20.
  • Such a pipe 20 with an umbraco screw will be securely mounted inside the telescoping pipe in the elevation pipes 2.
  • the top surface of the umbraco screw's head will, when the screw 22 has been screwed all the way inside the threads in the pipe 20, lie parallel with or inside the outer surface of the inner telescoping pipe 23.
  • the umbraco screw 22 may be rotated outwards for locking the outer telescoping pipe 24 relatively to the inner pipe 23.
  • the umbraco screw 22 is made with a collar 25 being larger than the holes 3 in the outer telescoping pipe 24 so that it will not be possible to screw the screw 22 out from its socket in the pipe 20.
  • a corresponding double-action securing screw as the one disclosed in relation to fig. 6 is shown in fig. 7 .
  • FIG. 8 there is shown an elevation jig system suitable for being used together with the pivotable chassis according to the present invention.
  • the elevation jig comprises here three jacking points I,II,III each being separately adjustable relatively to the elevation pipes 2,2'.
  • Such an elevation jig system may be elongated arbitrarily in its height by the aid of reciprocally telescoping pipe parts.
  • the jacking points I,II,III are secured to a lumber wall 25 where the lumber wall 25 is elevated from its foundation at the lowest I jacking point.
  • the elevation control comprises a pipe 27 running outside the scaffold pipes 2,2'. In the externally running pipe 27 that are placed holes 28 which may correspond to the holes 3 in the scaffold pipes 2,2' and through which there may be driven locking bolts.
  • a plate 29 protruding somewhat outside the edges of the pipe 27.
  • This plate 29 comprises securing devices 30 such as tracks for a beam/stay 26.
  • a friction wheel 31 breaking against the scaffolding 2,2' via a slot being arranged in the pipe part 27.
  • a second friction roller 32 Diagonally opposite the friction roller 31 there is preferably mounted a second friction roller 32 which also breaks against the internal pipe 2,2' via a second slot in the external pipe part 27.
  • pivotable substructure for an elevation jig is explained infra in relation to a special embodiment of pipes and elevation devices.
  • parts of the system according to the invention may be replaced with other and equivalently acting parts without straying from the object of the invention.
  • An example of such an equivalent embodiment is wherein the pivoting arms 6 are solidly connected to the base 4, and wherein the substructure/chassis 11 for the wheel/wheels 12 may be rotated relatively to this solid construction.
  • the piston 9 must of course be provided for a relative rotation between the chassis 11 and the base 4 and the pivoting arms 6.
  • a corresponding and equivalent embodiment is relevant concerning the pivoting plate 5 and the worm drive 8.
