Definitions

  • the invention is therefore based on the object to provide a method and a device for lifting and aligning buildings, which, while avoiding the aforementioned disadvantages, enables the removal of skewed positions of buildings or parts of buildings even if the masonry, based on a unit area, a has only a low load-bearing capacity.
  • the wall to be renovated is provided with core bores in a lifting plane, the spacing of which is determined according to the statics of the object to be renovated.
  • core bores essentially horizontally separated steel pipes are introduced, which have a load-bearing floor and a load-bearing ceiling, between which the cylinder-piston units are arranged.
  • These steel tubes take over the function of the known lifting chambers.
  • the outer walls of the steel pipes have bores and / or slots.
  • the bottom or the ceiling of a corresponding steel tube forms, together with the surrounding jacket surface, a pressure channel in each case, into which pressing material can be introduced.
  • This grouting material emerges from the steel pipe through the bores and / or slots and leads to a positive connection of the steel pipes in the surrounding masonry, in particular to the filling of existing gaps and cracks or the like in the masonry.
  • the grouting material is firmly integrated laterally and vertically in the pressure channel and between the ceiling shell and the floor shell, it is sufficient usually a material in the compressive strength and the composition of the found mortar.
  • the pressure applied by the cylinder-piston units is transferred over a large area to the surrounding masonry, so that the building can move.
  • This masonry 1 shows a schematic longitudinal section through a masonry 1.
  • This masonry 1 consists of a layer of stone blocks 2 and a layer of packing layers 3.
  • the layer of stone quarries 2 can (not shown) be bricked up without or with grouting, the layer of packing layer 3 is usually mortared.
  • a steel pipe 4 which is horizontally separated in two halves.
  • the steel pipe 4 has a ceiling 5 and a floor 6 parallel to one another.
  • a large number of cylinder-piston units 7 are arranged between the ceiling 5 and the floor 6 . When hydraulic pressure is applied, the footprint of the cylinder-piston units 7 presses against the floor 6 and the piston against the ceiling 5.
  • the ceiling 5 and the bottom 6 each form a pressure channel 8, 9 in the upper and lower half of the steel tube 4.
  • 4 slots or bores 10 are made in the outer skin of the steel tube.
  • an abutment 11 (shown schematically) is provided to absorb the shear forces in the masonry 1 and to set a prestress. Between the abutment 11 and the respective flanges of the steel tube 4 is a (only schematically shown biasing device 12).
  • the prestressing device 12 fixes the steel pipe 4 in the masonry 1.
  • connections 15 are connected to the respective pressure channels 8, 9.
  • a hardening material preferably mortar, concrete and / or epoxy resin, can be pressed into the pressure channels 8, 9 via the connections 15.
  • the compression material emerges from the pressure channels 8, 9 through the bores or slots 10 and can thus fill any cavities, non-compacted sand inclusions, sooty masonry or the like over the length of the steel tube 4 and thus a form-fitting, load-bearing connection between the steel tube 4 and manufacture the masonry 1.
  • the cylinder-piston units 7 are pressurized in a known manner and the lifting process is thus carried out.
  • the lifting gap 13, 14 can be clearly seen.
  • the lifting gap 13 is thin on one side of the masonry 1, while a pronounced lifting gap 14 can be seen on the opposite side.
  • a masonry 1 which is up for lifting or has already been lifted can also be exposed to considerable wind loads in individual cases.
  • the lifting gap 13, 14 cannot transmit these wind loads.
  • the cylinder-piston units 7 are usually removed from the inside of the steel tube 4 and the remaining cavity is cast with a resilient mass, for example concrete or a material mass similar to the building substance found. It is advantageous if a plurality of such steel pipes 4 are arranged within the masonry 1 of a building. As a result, the cylinder-piston units 7 located therein can be removed from a steel tube 4 and the concrete steel tube filled out, without fear of lowering again.
  • the steel tube 4 consists of a non-rusting material, preferably stainless steel.
