Definitions

  • the invention relates to a method for lifting, lowering and / or aligning a building or part of a building, in which the building or the building part is raised, lowered and / or aligned by means of a plurality of cylinder / piston units (1), the lowering being carried out in a first method step the foundation level of the building is determined as the actual travel value, the respective travel value is compared with the actual travel value, and subsequently the cylinder-piston units (1) are actuated depending on the result of the determined actual travel values and the travel-dependent activation of the cylinder Piston units (1) via a controlled system and central controller (11), which is a computer.
  • a controlled system and central controller 11
  • the invention also relates to an apparatus for performing this method.
  • Methods of the type mentioned are used in particular to correct the imbalance of buildings occurring in mining areas.
  • the surface of the site changes so much due to the collapse or collapse of tunnels and the subsequent sinking of the ground that the buildings are inclined, tilted or tilted in whole or in part.
  • the changes in the terrain surface do not take place in a uniform, level manner, but that certain areas of the terrain sink more than others.
  • this leads to considerable misalignments, which in extreme cases can lead to severe building damage.
  • This damage to the building is particularly caused by different pressures in the horizontal and vertical directions.
  • a device according to the preamble of claim 13 is also known from EP-B1-43078.
  • DE-A-3633473 discloses a method for hydraulically undertaking a building during its relocation.
  • a building located in the shift is controlled via lifting elements in such a way that its original vertical standing axis is essentially retained, ie, based on the position of the building, changes in position due to flexible embedded flexible displacement tracks are compensated.
  • This procedure is based on an actual position of the building and tries to maintain this actual position even with flexible displacement tracks.
  • the invention has for its object to provide a method of the type mentioned and a device for performing this method, which with a simple structure and easy handling of the device enable the alignment of a building so that this again in terms of static requirements an exact location can be brought, whereby damage caused by the movement of the building should be avoided.
  • each of the cylinder-piston units is actuated until a load, which is predefined from the statics of the building for the location of the cylinder-piston unit, is reached, the target force values for each cylinder-piston unit being stored in the central computer, the contact forces on each cylinder Piston unit, measured during the distance-controlled lifting, at intervals or continuously and entered into the central computer, the central computer compares the target force values with the actual force values and the control signals for the actuation of the individual cylinder-piston units taking into account the result of all determined target Forms actual force values in such a way that the same possible load is present on all cylinder-piston units.
  • the method according to the invention is distinguished by a number of considerable advantages. While in the previously known method there was only a path-dependent straightening or alignment of the building, it is now possible according to the invention to carry out the alignment, raising or lowering of the building in such a way that the load imposed by the structural analysis is present at the respective building locations. It is thus ensured that the parts of the building which are intended to introduce the forces into the ground can also absorb these forces in a corresponding manner. In contrast, there is a correspondingly lower burden the parts of the building that are, for example, not load-bearing or are only slightly loaded.
  • the method according to the invention also makes it possible to align buildings in which the respective foundation base of the structural system was no longer a flat level, but rather an uneven surface that is inclined in several dimensions.
  • the outer edges of the building may have different inclinations, so that when determining a new target level in which the building is to be aligned, the oblique surface of the foundation base must be averaged.
  • the original foundation level of the building is subdivided into individual contiguous sub-levels and that the individual sub-levels are aligned independently of one another with the associated cylinder / piston unit. It is thus possible to level and / or align the sub-levels completely independently of one another, so that even larger buildings in which only certain parts have been lowered or moved can be restored to their original state.
  • a theoretically first target level is determined for each sub-level by determining the average inclination and the position of the axis of rotation of the building.
  • the alignment can thus take place in such a way that the first target level is reached. If several or larger lifting, lowering or aligning processes are required for complete alignment of the building, then according to the invention when the first is reached A further target level to be reached step by step is to be determined. In the same way, a large number of target levels can be specified, so that even larger subsidence of the building can be compensated for.
  • the necessary travel paths of the building are calculated using a specially developed computer program after the originating misalignment and the respective axis of rotation have been determined.
  • the coordinates of the individual lifting points of the building were determined in the elevation analysis.
  • lifting chambers are provided in which the respective cylinder-piston units are used.
  • the location of the lifting points results from the design of the firm letters to be lifted from the building and from the compressive strength of the building structure above the lifting chambers.
  • the magnitude of the forces to be transferred or applied at the individual lifting points is determined in the lifting statics.
  • the individual lifting units or cylinder-piston units can be controlled differently and can exert different forces, single-way control and single-force control at the respective lifting points are possible.
  • the individual cylinder-piston units are activated via a central computer, in which the respective force and / or displacement values are stored and compared with the actual values. It is still possible to document the movement of the building.
  • the recording of the measured values, from which the respective position of the building can be determined, is preferably carried out via a hose balance system, which is defined either at the intersection areas of adjacent sub-levels or at the outer areas or outer edges of the sub-levels in its measurement points.
  • the first procedure is to use pressure control in the hydraulics to set the respective force which is to be applied by the lifting unit and which was determined in the survey statics for each lifting point.
  • the entire building stands on the cylinder-piston units without any relative shifts in the base area.
  • the previously low level of the building is checked by a surveyor. This makes it possible to take necessary corrections for the last stroke into account again and enter them in the central computer in order to calculate new stroke heights and to forward them automatically to the microprocessors of the individual stroke units or cylinder-piston units.
  • the force transfer in the building is checked. It is possible to redistribute peak loads and optimize load transfer in the individual panes of the building.
  • an alignment of the building is thus possible without affecting the static structure of the building are to be feared.
  • the lifting kinematics generated in this way can be checked and, if necessary, can be tested by a test statistician.
  • This attestation means that no interventions were carried out during the uplift into the structure of the house or building that caused the building structure to deteriorate. Rather, it is possible according to the invention to optimally deposit the building structure or the building onto the new foundations using the method.
  • the method according to the invention thus fulfills the requirements of the test statics for a method for such complex tasks.
  • the method according to the invention is further characterized by a high degree of safety during the lifting process, since peak loads, which can occur during lifting, can be recognized and derived in good time.
  • Another advantage with regard to the safety of the method is that a large number of individual cylinder piston elements are used, so that if one element fails, the safety of the lifting process is not impaired.
  • the respective load values can be monitored of the lifting units errors are recognized immediately and a hazard to the building can be avoided by interrupting the lifting process.
  • Ischebeck wedges mechanically trailing under the cheeks of the lifting chambers are arranged in parallel, which can immediately take over the load if the cylinder-piston unit fails.
  • a piston-cylinder unit 1 is connected to a displacement sensor 2.
  • the piston-cylinder unit 1 is supplied via a supply unit 3, consisting of a motor 4, which drives a pump (not shown) located in an oil pan 5.
  • a control unit 6 is arranged between the piston-cylinder unit 1 and the supply unit 3.
  • a pressure meter 7 is located between the control unit 6 and the piston-cylinder unit 1.
  • the analog measured values coming from the displacement sensor 2 or from the pressure meter 7 are converted into digital signals by analog-digital converters 8, 9, which in turn are sent to the individual controller 10 be fed.
  • the individual controller 10 in turn forwards the data to the central controller 11 and also receives its instructions from it, which it in turn forwards to the control unit 6.
  • a large number of individual controllers, comparable to the individual controller 10, can be connected to the central controller 11. In the schematic sketch, only three such connections are shown.
