Definitions

  • the invention relates to a method for undertaking of buildings, according to the preamble of claim 1, and a method for forming reinforced concrete support elements, according to the preamble of claim 16.
  • GB-A-2 254 631 teaches parts of the masonry in the immediate vicinity To be removed near the ground or in the foundation area and stiffened with a reinforced concrete skeleton. With dilapidated or dilapidated structures or buildings this represents one considerable interference with the existing building fabric significant risks.
  • US-A-3,345,824 teaches the sealing of under-rinsed Buildings to be filled with concrete, if necessary iron armored sacks.
  • a cloth tube inside a cylinder made of wire mesh or the like arranged, being inside the fabric hose another wire mesh cylinder can be arranged.
  • the Fabric hose is together with the outer wire mesh cylinder squeezed under a foundation washed in by water and then pressed out through a pipe with a concrete mixture, until it goes through the outer wire mesh cylinder dimensionally stabilized, concrete filled hose between the Underside of the washed-out foundation and the opposite Bottom pressed, the inner wire mesh cylinder forms a kind of reinforcement.
  • WO-A-86/03532 teaches approximately according to the figures there 1 to 5 on the side next to the building to be underpinned to drill a horizontal shaft or tunnel. That tunnel runs between a start and a target shaft and must have a diameter that the insertion of the high-pressure injector, as shown in FIG. 3. Furthermore, this tunnel needs the considerable Must have a diameter so that a human being can at least get involved in it bent over or crawling, in regular motion Distances lateral breakthroughs through which an injection lance from inside the tunnel to the neighboring one Soil can be pushed. It is therefore about a "work tunnel" to the side of the building from which partially penetrated from under the building becomes.
  • FR-A-2 686 356 suggests going out from a starting shaft under the building a horizontal one To advance the shaft or tunnel towards a target shaft. The shaft is then filled with concrete, with one or more tie rods embedded become. The tunnel is driven in such a way that the or the foundations of the building pierced or be pierced. Given that to be underpinned Buildings in the vast majority already one have more or less damaged building structure appears drilling or puncturing the foundations is extremely questionable because risky. For example, when renovating Jordan would apply the procedure under FR-A-2 686 356 mean that the individual column foundations are pierced or need to be pierced. This poses a risk represents which probably no renovation company undertake would like to.
  • a first aspect of the present invention accordingly becomes a process for undertaking buildings created in which at least one support element under the structure is formed, and characterized in that is that the at least one support element is elongated / rod-shaped is trained; and that at least a support element substantially parallel to and below from a foundation of the structure in one previously trained there Hole is arranged.

  • the invention makes it particularly advantageous Way that an entire foundation section of a Structure can be supported.
  • the support element becomes the subsurface not so badly affected under the foundation that there are settlements.
  • Another major advantage is that the Risk of accident for the people working there is essential can be reduced as this is not immediately below the wall to be underpinned, but laterally spaced from the building.
  • Another advantage of the method is that common means in construction engineering and sewer construction can be applied.
  • the one required for implementation Technology is therefore available and relatively inexpensive.
  • support elements in the form of a grid or Grid can be arranged, in particular at larger buildings, such as churches or the like. an effective undertaking of the entire structure become. Buildings of this type are usually constructed in such a way that the load of the structure on a grid of load-bearing Supports columns. These pillars are partly in the side walls and partly inside the building. By the grid-shaped The arrangement of the support elements becomes a targeted support of the respective load-bearing element possible. On gentle undertaking of the entire static support points of the building is therefore possible.

  • the upright holes are made with concrete and preferably steel reinforced concrete filled, the particular is introduced by high pressure injection. So that becomes a certain displacement of the unstable subsurface under the Foundation reached and the room filled with concrete. Provided if the subsurface cannot be ousted, it will be so far condenses that it is now stable.

Even with that stable undertaking of the supporting element can be achieved.
  • reinforced concrete support elements can be therefore significantly simplify by after the manufacturing process of the hole, steel strands are individually inserted into the hole and during the installation with additional reinforcement elements to be connected to a reinforcement.
  • the reinforcement is connected to the tension element and pulled through this into the hole.
  • the advantage here is that the reinforcement is inserted in the bore is guided, and further that an insertion means Traction is much easier to manage than insertion by means of pressure forces. The danger of getting caught the reinforcement with the hole wall and thus one Blockage is significantly less.
  • the reinforcement is on the end connected to the traction element is not yet full is trained and e.g. forms a cone shape that is relative simply slides through the hole.
  • the steel cable with the attached Reinforcement using a preferably arranged in the target area Winch is pulled through the hole, can apply the forces required to insert the reinforcement be reliably applied. Furthermore, the progression of the introduction are controlled continuously, whereby a jerky slip or the like, e.g. when pulling in by hand due to a hooking of the Reinforcement with the bore wall can be prevented can be.
  • the reinforcement during withdrawing the drilling device or the drive to the drilling device in the start area in the hole is drawn in. It can be used to introduce a Tension element are dispensed with, since the retraction movement of the Drilling device as a drive for inserting the reinforcement Application. Arranging the reinforcement in the This further simplifies drilling.
