Definitions

  • the invention relates to a method for erecting concrete walls using braced formwork according to the preamble of claim 1.
  • the invention also relates to a pipe spreader and 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 inventor has recognized that when the space between the formwork panels is filled with liquid concrete and when the concrete subsequently hardens, cavities and / or cracks form in the adjacent area of the casing of the pipe struts, which can extend to the outer surfaces of the concrete wall erected or extend in the Expand over time into the outer surfaces so that the watertightness of the erected concrete wall cannot be guaranteed.
  • 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 clamping points are made watertight.
  • a pipe spreader and a simple, functionally reliable device for performing the method are to be created.
  • the process according to the invention creates voids or cracks between the pipe jacket and the concrete wall material during the filling of the pipe struts, so that the clamping area of the concrete wall is reliably sealed watertight.
  • the conventional method only the pipe itself was sealed. The leak in the outer area of the jacket of the pipe was not recognized at all. By filling the interior of the pipe, however, the seal to the lost pipes of adjacent cracks and cavities in the concrete walls could not be sealed. The waterproofness of concrete walls in this disturbed area is achieved by the invention.
  • a pipe spreader or a clamping point pipe is used, which is provided with passages in the jacket, which with a z. B. outside on the tube cuff from a z. B. are covered by resilient material.
  • the pipe according to the invention can be used like a conventional pipe spreader together with the tension anchor, since liquid concrete filled between the formwork panels cannot penetrate into the holes or openings formed in the pipe jacket due to the sleeve.
  • the openings are preferably formed at least in the longitudinal center region of the tubular jacket.
  • the tubes are uniformly continuous or have inner walls.
  • the sleeve sealing or covering the pipe breakthroughs can consist of a material that resists the liquid concrete until it has hardened.
  • the following is therefore suitable as a sleeve material: Paper or cardboard, these preferably being impregnated to resist moisture or provided with a water-permeable outer layer.
  • a preferred device for performing the invention Method using the z. B. perforated tube as a tube spreader with an applied sleeve comprises an insertable into the tube spreader injection device in the manner of a so-called.
  • Packer which has an injection tube, 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.
  • the method according to the invention and the pipe spreader according to the invention are used for the injection of a sealing medium into a sealing device for sealing a joint formed between two concreting sections.
  • 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 clamping point tube or a pipe spreader 4 is arranged, which is equipped with conical dents 5 and 5a adjoining the inner surfaces of the formwork panels 1 and 2 and seated in the openings of the tube spreaders 4.
  • the dents 5, 5a which are supported over their entire surface on the inner surfaces of the formwork panels 1 and 2, extend with the other ends into the pipe struts 4 and have through holes which are penetrated by the tension anchor 3, which also the pipe struts 4 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 tube wall of the clamping point tube or the tube spreader 4 is in particular in its longitudinal center region with a plurality of passages z. B. perforated in the form of holes 11.
  • the holes 11 are covered with a sleeve 12 which is drawn onto the longitudinal center region of the tensioning tube 4 and has a length which ensures that all the passages 11 are closed. Due to the use of the sleeve 12, the pipe struts 4 can be installed and used in a conventional manner, because the sleeve reliably prevents liquid concrete from penetrating into the passages 11.
  • an injection device in the manner of a packer 10 is introduced into the pipe 4.
  • the injection device has a tube 13, in the tube jacket openings in the form of z.
  • holes 15 are introduced and the outer diameter is smaller than the inner diameter of the lost tube 4, so that an annular cylindrical space 13a is formed between the packer tube 13 and the lost tube 4.
  • the packer 10 is inserted with its tube 13 into the sleeve area of the tube spreader 4.
  • the end of the packer tube 13 is through circular disks 13b completed, the diameter of which corresponds to the inside diameter of the lost tube 4. Outside on the disks 13b z.

  • 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 4.
  • the sealing plugs 16 are configured, for example, like a balloon, and compressed air can be fed to them, not shown, so that the sealing balloon is clamped in the radial direction against the inner wall of the tube.
  • 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 escaping in the radial direction and thus being braced against the inner wall of the tube 4. In any case, an end seal of the pipe struts 4 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 passes through the holes 15 to the holes 11 of the pipe spreader 4 and through the holes 11, as shown by arrows in FIG. 3, under and out of the sleeve 12 into cracks and cavities in the concrete wall 20 which occur during filling and hardening of the liquid concrete are left in the area between this and the jacket of the tube 4, so that this critical area is reliably sealed.
  • the packer 10 is pulled out of the pipe 4 after the sealing plugs 16 have been relaxed, and the pipe interior is z. B. filled with a known injection packer with potting material, so that the concrete wall in the area of the pipe spreader 4 is completely sealed.
  • the sleeve 12 expediently has at least one valve slot 12a, preferably a plurality of valve slots 12a, which are preferably not arranged over a hole 11 (FIG. 2).
