Definitions

  • the invention relates to a method for lifting, lowering and / or aligning a building, in which the building is raised, lowered and / or aligned by means of a plurality of cylinder-piston units, the inclination of the foundation level of the building being determined as the actual value in a first method step and the cylinder-piston units are actuated depending on the travel.
  • 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.
  • EP-B1-43078 discloses a method in which a multiplicity of cylinder-piston units are used, by means of which the building can be raised, lowered and / or aligned in such a way that the subsidence that has occurred is compensated for.
  • the distances covered by the individual cylinder-piston units are measured, so that the necessary lifting or lowering paths can be determined for the individual cylinder-piston units, taking into account the inclination of the foundation level of the building before the alignment of the building are necessary.
  • This method proves to be sufficient in many other cases, especially for smaller or lighter buildings.
  • there are a large number of applications in which a purely path-dependent alignment of the building in the area of the individual cylinder-piston units is not sufficient. In the case of larger buildings in particular, which have become twisted due to the lowering of the terrain, it is not sufficient to just straighten the building depending on the path, since the requirements given by the statics of the building cannot be adequately taken into account.
  • the invention has for its object to provide a method of the type mentioned which, with a simple structure and easy handling, enables the alignment of a building so that it also with regard to the static requirements changes can be brought back into an exact position.
  • each of the cylinder-piston units is actuated until a load predetermined for the location of the cylinder-piston unit is reached from the statics of the building.
  • 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 specified by the structural analysis is present at the respective building locations. It is thus ensured that the parts of the building which are provided for introducing the forces into the ground can also absorb these forces in a corresponding manner. In contrast, there is a correspondingly lower load on the parts of the building which, for example, are not load-bearing or are only loaded to a small extent.
  • a further target level to be achieved step by step is to be determined.
  • a large number of target levels can be specified so that even larger subsidence of the building can be compensated for.
  • the necessary lifting 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 uplift statics.
  • 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 control of the individual cylinder Piston units 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 that is to be applied by the lifting unit and that 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-lying position of the building is checked by a surveyor. This makes it possible to take necessary corrections for the last stroke again into account and enter them into 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 can be monitored values 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.
  • the foundation area of the building in relation to the lower edge of the basement ceiling is taken up from the outside with a fine alignment element. It is determined how changed the original foundation level during the subsidence.
  • the existing foundation area is divided into individual contiguous sub-levels. The position of the individual sub-levels relative to one another is an important parameter for controlling the load distribution in the foundations.
  • a theoretical first target level for lifting and lowering is specified from the position of the founding surface, by specifying the average inclinations and the position of the axis of rotation for the raising or lowering.
  • the axis of rotation can lie within the structural system or the building.
  • the first theoretical target level thus determined is determined anew after a first uplift step has taken place.
  • the geometry of the foundation surface and the load distribution in the foundations is gradually approximated to the original state, so that the damage is healed from the Mountain subsidence is made.
  • the position and arrangement of the lifting chambers are derived from the requirements of the statics as well as from the geometric lifting plan, after connected lifting units have to be formed, which allow separate control of the sub-levels.
  • the sub-levels are raised or lowered about their axis of rotation with the neighboring level in such a way that the path forced by lowering the mountain is reversed as much as possible. It is controlled until the correct force distribution is achieved.
  • the twisted foundation surface is not to be transferred into one plane, but rather a load distribution corresponding to the statics is achieved, the counter-movement being raised or lowered from the mountain depression.
  • the method according to the invention enables the lifting or lowering process to be stopped with the entire system, if necessary, and only to be continued with a partial level and only with new control parameters.
  • the new actual values are then automatically transferred to the central computer and the entire system is continued drive.
  • measuring points of a hose trolley system are attached at the intersections of neighboring sub-levels and at the outside corners.
  • the individual lifting units are approached uniformly for a load transfer of 10 tons per lifting unit on contact. Then it is lifted in parallel with a path of one millimeter. The power transfer is measured at the individual lifting points.
  • both the power transfer and the measuring points of the absolute distances on the hose scale are observed.
  • the two values determined correspond to each other, since when the foundations go off, there is also a reduction in the amount removed forces occur in the sub-plane.
  • the actual raising and lowering process begins at the end of the consultation period.
  • the maximum lifting height at the highest point results from the middle inclination and the distance of the axis of rotation of the levels from the building.
  • the maximum lifting height is divided into partial lifts, with the lifting height per partial lifting being a maximum of 15 cm.
  • the respective piston-cylinder unit is then implemented. The lifting is carried out in 1% steps so that the maximum single stroke at the highest point is 1.5 mm.
  • the force distribution is read for 5% intervals. Continuous reading is possible at critical points.
  • the read values are plotted in a diagram, with deviations from the target distribution leading to a corresponding increase or decrease in the sub-levels until the optimal force distribution is achieved.
  • the individual lifting devices are moved.
  • the mechanical lifting wedges attached to the side are tightened so that the pressure in the respective lifting unit drops.
  • This lifting unit is then lowered to zero and placed vertically on a horizontal abutment. After that, the printing will start again before moving started.
  • the new zero heights are adopted by the central computer.
  • 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 are 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.
