Definitions

  • the invention relates to a corrosion-protected tension member, in particular a tendon for prestressed concrete, according to the preamble of patent claim 1.
  • the prestressing is known and without composite.
  • the tendons are located longitudinally movable within the concrete cross-section and are after clamping against the hardened concrete by injecting cement paste in conjunction with it brought surrounding concrete.
  • the tendons are located usually outside the concrete section, but are opposite the building supported; They can be visited at any time, re-tensioned and possibly also be replaced.
  • tension members of this type so-called “monostrands” are often used as tension members.
  • used that is strands of seven steel wires, which protect against corrosion each of an applied by extrusion coat of plastic, for Example Polyethylene, enveloped and from one the gussets between the steel wires and filling the annulus between the strand and sheath Anticorrosion compound, for example, fat, are surrounded; they are also strands known to provide increased protection against corrosion of two such coats are surrounded.
  • the anchorages of the strands at the ends of the tendons are usually from steel anchor plates with conical, then cylindrical holes in the number of strands through which these are inserted and in which they anchored multi-part ring wedges.
  • To anchor the strands it is in each Case necessary to remove the coats of strands in the area of anchorages, so that the anchoring wedges can attack directly on the bare strands.
  • Tendons without composite, which so far essentially as external, that is outside the concrete cross section guided tendons were used experienced increasingly also use as internal tendons, that is within the Concrete section lying tendons.
  • internal tendons As within the concrete section arranged tendons have advantages in static terms, namely with regard to the exploitable lever arm of internal forces;
  • the Clamping force can be controlled by retightening, which in case of prestressing with composite not possible.
  • this type of tendons it is possible to be able to exchange individual tension elements or even the entire bundle.
  • a particular advantage over external tendons is that the Tensioning elements are embedded in the concrete, so that the resulting at deflection points Deflection forces can be absorbed without special measures. In this Often also strands with reinforced coat or double are connected extruded strands used.
  • the invention has the object, a simpler and more economical way of sealing the anchoring area of a generic tension member, in particular for use as a tendon without Composite, to create not only a simple assembly, but also a easier replacement of individual strands and the possibility of using double extruded strands opens up.
  • the main advantage of the invention is the activation of the Gland sealing of the anchoring area by additional Steps to be operated as from the air side of the anchorage ago To avoid bolts or the like.
  • the Rather, seal activated in a simple way that the armature disk in the Assembly of the tension member by pressure-transmitting means in a predetermined Distance is held by the anchor body and that during clamping of the Werglieds taking place longitudinal displacement of the armature disk in the direction of the Anchor body out through the pressure-transmitting means the required surface pressure is exerted on the turn against longitudinal displacement fixed sealing elements.
  • the sealing disc serves as a spacer for the individual tension elements provided perforated disc as an abutment for the sealing disc, for example may be made of soft rubber or foam.
  • this must be the Perforated disk through an abutment on the tubular part of the anchor body on a Longitudinal displacement are hindered; This can be done by appropriate types of Stops on the inner wall of the anchor body happen. If necessary, can also a steel plate for generating a three-dimensional clamping state in the perforated disc are interposed. Through this activated Transverse deformation of the gasket is the cavity against both the PE coats the Strands as well as against the inner wall of the anchor body as an outer cladding reliably sealed.
  • Fig. 1 the anchoring portion 1 of an inventively designed Buchglieds 2 shown in a longitudinal section.
  • the tension member 2 is in the illustrated case a tendon, which, as Fig. 2 reveals, from fifteen individual tension elements 3 exists.
  • the tension elements 3 in turn consist of so-called “monostrands", the means steel wire strands 4, which are used for the corrosion protection of enclosures 5 made of plastic, in particular PE, are surrounded.
  • the spaces between - not shown - individual wires of the strands 4 and the PE jacket 5 are provided with a Corrosion protection material, such as grease, filled.
  • the strands 4 are in an anchor plate 6 made of steel by means of multi-part annular wedges. 7 anchored.
  • the armature disk 6 is provided with bores having a inner cylindrical portion, the air side in a conical Range passes (Fig. 1a).
  • the armature disk 6 is supported in the outer surface 8 of a structure via a Intermediate ring 22 against a flange abutment ring 9 of a tubular Anchor body 10 from which is cast in the building.
  • the anchor body 10 forms in Anchoring area 1, the tubular envelope of the bundle of tension elements 3, then, optionally by means of a transition piece 11, in another Casing 18 can pass.
  • a transition piece 11 for the piping 18 may be smooth or profiled PE pipes, sheet metal pipes or the like can be used.
  • the transition piece 11 consists of plastic, mostly PE; at the same time it serves as a soft diversion for the tension elements 3.
  • the invention extends mainly to the connection of the already applied in the manufacture corrosion protection of the tension elements 3 the anchorage, since in the actual anchoring area, the PE sheaths 5 of Tension elements 3 must be removed so that the wedges 7 directly to the bare Strands 4 can attack.
  • tension member 2 While in the normal range of tension member 2 between the Anchoring areas 1 tightly packed tension elements 3 in the area of Transition piece 11 are spread outwards to them in the area of Anchor plate 6 for anchoring by the ring wedges 7 required distance to bring when entering the actual mooring area they will be replaced by a Spacer acting perforated disc 12 back to the longitudinal axis of the tension member diverted.
  • the perforated disc 12, which consists of plastic and with corresponding Holes is provided is dimensioned so that the tension elements 3 parallel to the Axes of the wedges 7 are guided and that they are the resulting, radially to Longitudinal axis directed towards deflecting forces can absorb.
  • the perforated disc 12 in turn serves as an abutment for a sealing washer 13 soft rubber or foam, with the help of a pressure plate 14a Steel can be brought under surface pressure.
  • a pressure plate 14a Steel can be brought under surface pressure.
  • the perforated disc 12 must be secured against longitudinal displacement. This happens in the example shown by a stop tube 15, which on the inner wall the anchor body 10 is applied and secured thereto, for example by screws is.
  • the protection against longitudinal displacement can also be done by that in the anchor cast body 10 made of cast steel on its inner wall corresponding stop is formed.
  • a further steel plate 14b may be arranged. These Steel plate 14b also supports the perforated disc 12 when receiving the Deflection forces.
  • a pressure tube 16 For applying an axial pressure on the sealing disc 13 by means of Pressure plate 14a is a pressure tube 16, which is the entire bundle Tension elements 3 within the anchor body 10 surrounds and with respect to this is longitudinally displaceable.
  • the length of this pressure tube 16 is dimensioned so that it at the mounting of the anchorage to the degree of compression of the Gasket 13 protrudes beyond the outer surface of the abutment ring 9.
  • the positioning of the armature disk 6 during clamping takes place against the Sealing disk 13 is pressed, whereby this by the appropriate degree is compressed.
  • the cavity within the anchor body 10 against both the PE sheaths 5 of the strands 4 and against the inner wall of the anchor body 10th sealed As a result of the thereby activated transverse deformation of Sealing disk 13, the cavity within the anchor body 10 against both the PE sheaths 5 of the strands 4 and against the inner wall of the anchor body 10th sealed.
  • pressure plate 14a - sealing disc 13 - perforated disc 12 and optionally steel plate 14 b and by the dimensioning of Perforated disk 12 is also the often occurring in known anchorages Disadvantage avoided that the tension elements 3, especially in non-ordered Installation can be displaced in the transverse direction during clamping in the seal and thereby leaks arise.
  • a retaining plate 17 from Steel arranged on the inside of the armature disk 6 .
  • This retaining plate 17 has holes that just the Allow passage of the bare strands 4, while surrounding the strands PE sheaths 5 on the retaining plate 17 find a stop (Fig. 1a).
  • the retaining plate 17 is provided with additional holes, so that the corrosion protection compound in the holes of the armature disk 6 and in the Slots can penetrate between the parts of the ring wedges and there for a perfect corrosion protection of the strands 4 ensures.
  • the assembly of the anchoring training according to the invention can be with reference to FIG. 3 be explained.
  • the anchor body 10 connected to the tubing 18 produced in the required length and in the Formwork of the concrete structure concerned installed.
  • the tension elements 3, that is surrounded by PE sheaths 5 strands 4, are before or after the introduction of the Concretes fed or pushed in a conventional manner.
  • the two PE sheaths When using double-extruded strands, ie strands, the two PE sheaths have previously been the outer PE jacket at a certain distance from to disconnect and remove tensioned strand end. Then the inner PE jacket so far away that he after tightening in the with anticorrosion compound to be filled area 19 of the anchorage ends. The previously peeled outer PE jacket is then postponed again, with the remaining outer jacket connected and cut so far that he is already in the assembly in the Corrosion protection compound to be filled area 19 binds.
  • This distance corresponds to the Compressibility of the sealing washer 12, which then activated in this way is when the armature disk 6 during the tensioning of the strands 4 to the corresponding Route in the anchor body 10 penetrates until it - with the interposition of the Intermediate ring 22 - supported on the abutment ring 9.
  • the clamping channel that is, the cavity between the tension elements 3 and the Piping 18, usually remains free to a possible replacement of Single strands or the entire bundle to simplify.
  • a backfilling for example, to prevent the ingress of water can a non-hardening material such as bentonite or one with less Strength-hardening material such as cement mortar with plastic additive, For example, Styrofoam, to be pressed, which may easily be removed again can be.
