Definitions

  • the invention relates to a method for erecting a concrete wall using tensioned formwork according to the preamble of claim 1.
  • the invention also relates to a device for performing the method.
  • the generic method is used to erect concrete walls.
  • the formwork panels are arranged parallel to each other with a distance corresponding to the thickness of the concrete wall to be erected.
  • Tension anchors are used for fixing and bracing the formwork panels, whereby pipes, so-called pipe spreaders, are used as formwork spacers and counter anchor elements, which are penetrated by the tension anchors and are supported by so-called conical dents on the inside of the formwork panels.
  • the formwork panels are braced against each other using screw elements that can be screwed onto the ends of the tension anchors outside the formwork, such as large-sized wing screws.
  • the formwork arrangement prepared in this way is then poured on site with concrete.
  • the formwork panels are removed by first unscrewing the screw elements on the ends of the tie anchors and then pulling the tie anchors out of the pipes or pipe braces.
  • the conical dents are still removed from the pipe ends, while the pipe spreads remain as lost parts within the concrete wall, which is thus perforated several times throughout due to the pipe spreads left behind.
  • These wall passages are filled with grouting material, for example with special swelling grout. Filling is conventionally carried out by closing the pipe spreader at one end with a cover, while the potting material is introduced from the other pipe side using a filling syringe. The end cover has a perforation so that displaced air can escape through the filling.
  • the present invention has for its object to provide a method for erecting concrete walls by means of formwork of the type mentioned, with which the pipe brackets or sealing devices to be pressed with potting material can be easily pressed.
  • a preferred device for carrying out the method according to the invention comprises an injection device, which can be inserted into the pipe spreader, in the manner of a so-called packer, which has an injection pipe, the jacket of which is provided with injection openings or injection nozzles.
  • the injection tube is sealed on both sides. The radial sealing and bracing of the packer on both sides to create a sealed injection area in the pipe spreader takes place, for. B. with rubber sleeves on the injection tube.
  • Swelling grout is usually a mixture of Potland cement, finely graded quartz sand and reactive chemical additives that provide the desired swelling effect.
  • a sealing device is described for example in EP-A1 0 418 699. It is a passage as an injection path for a body forming a sealing medium in the joint area on the concrete surface of the one concreting section, from which, after the second concreting section has been built, the sealing medium emerges when the concrete is injected into the joint area between the two concreting work in the joint area .
  • the bodies are channel-shaped structures, as described in EP-A1-0 418 699, or porous hoses according to CH-PS 600 077, which according to DE-GM 83 35 231 can have support bodies in the form of a helical spring, or according to DE -GM 86 08 396 can be a sealing device in the form of an injection hose, which on the one hand eliminates the disadvantage of positioning the hose by means of tabs provided on the hose body and on the other hand have a predetermined breaking point in the longitudinal direction of the hose-like body, through which the sealing medium is to escape into the concrete.
  • the sealing medium is usually pressed directly into the beginning or end of the hose.
  • EP-A1-0 418 699 proposes drilling the channel described in this document after the second concrete section has hardened and stripped through a hole in the hardened concrete and pressing the sealing medium through the hole into the interior of the sealing device .
  • the channel should be equipped with a larger target hollow body at the locations where the bore is to be drilled, so that the drilling of the bore can be carried out more easily and the channel can be hit more safely.
  • the process for loading sealing devices of this type with sealing material is simplified in that the pipe spreads already located in the concrete wall are used for this purpose. It is therefore no longer necessary to drill the concrete from the outside or to create special facilities so that the end or the beginning of an injection hose or injection channel is led outside.
  • Fig. 1 shows the detail of a formwork for erecting a concrete wall before filling in liquid concrete.
  • the formwork has two formwork panels 1 and 2, which are equipped with anchors and are kept at the same distance from each other.
  • the anchors each have a tension anchor 3, z. B. in the form of a threaded steel rod at the end.
  • a tensioning point tube or a pipe spreader 40 Arranged between the formwork panels 1 and 2 is a tensioning point tube or a pipe spreader 40 which is equipped with conical dimples 5 and 5a adjacent to the inner surfaces of the formwork panels 1 and 2 and seated in the openings of the tube spreaders 40.
  • the dents 5, 5a which are supported with an end face over their entire surface on the inner surfaces of the formwork panels 1 and 2, extend with the other ends into the pipe struts 40 and have through bores which are penetrated by the tension anchor 3, which also the pipe struts 40 and one hole each in the formwork panels 1, 2 interspersed.
  • the anchoring is braced using wing screws 6 and 7, which are screwed onto the threads provided on the end of the tension anchor 3 and act on the formwork panels 1 and 2 via large washers 8 and 9.
  • the formwork so tensioned is conventionally poured with liquid concrete. After the concrete has hardened, the formwork panels 1 and 2 are knocked off, with the tensioning anchor 3 together with the tensioning screws 6, 7 and the washers 8, 9 being removed beforehand. The dents 5 and 5a are then pulled out of the concrete wall 20; the pipes 4 remain as lost parts within the concrete wall 20.
  • the finished concrete wall 20 is shown in the area of a lost pipe spreader 40 in FIG. 3.

  • other identical injection routes known per se can also be connected to the pipe socket 41 in the same way.
  • Fig. 3 the concrete wall 20 is shown, which was created after pouring concrete into the formwork shown in Fig. 1, after hardening of the concrete and after knocking off the formwork panels 1 and 2, after previously the tension anchor 3 together with the tensioning screws 6, 7 and the washers 8 and 9 and the dents 5 and 5a have been removed.
  • An upper pipe 4, the lower pipe 40, the connecting hose 42 and the injection channel 43 remain as lost parts in the concrete wall 20.
  • sealing medium is injected, for example, by means of an injection packer via slots or openings 11 in the pipes 4 and 40 into cavities and cracks outside the pipes 4 and 40 introduced.
  • sealing medium or potting material is introduced into the pipe 40, via the pipe socket 41 and the connecting hose 42 into the injection channel 43, which is completely filled with the pressurized potting material or sealing medium, which over the free longitudinal edges of the channel 43 into the joint area 45 and possibly in Cracks or cavities can emerge, which are present between the concrete wall 20 and the outer region of the injection channel 43.

  • the packer 10 is inserted with its tube 13 into the sleeve area of the tube spreader 40.
  • the end of the packer tube 13 is through circular disks 13b completed, the diameter of which corresponds to the inner diameter of the lost tube 40. Outside on the disks 13b z. B.
  • sealing plug 16 made of an elastic material.
  • One sealing plug 16 has a central passage which is aligned with a passage in the adjacent disk 13b, a hose 14 being connected to the passage of the sealing plug 16.
  • the two sealing plugs 16 are expandable in the radial direction for bracing against the inner wall of the tube 40.

  • the two sealing plugs 16 can be cylindrical sealing disks which are acted upon by an axially acting compression device, the sealing disk material compressed in the axial direction evading in the radial direction and thus being braced against the inner wall of the tube 40.
  • an end-side sealing of the pipe struts 40 is achieved by the compressed sealing plugs 16.
  • Potting material is fed into the pipe 13 under pressure via the hose line 14. Potting material reaches the pipe socket 41 of the pipe spreader 40 via the holes 15.
  • the packer 10 is pulled out of the pipe 40 after the sealing plugs 16 have been released, and the pipe interior is conventionally, e.g. with an injection packer known per se, filled with potting material, so that the concrete wall in the area of the pipe struts 40 is completely sealed.
