Definitions
- the invention relates to a method for installing and tensioning a freely tensioned tension member, for example a stay cable for a Cable-stayed bridge, an external tendon or the like from a bundle of plastic-coated individual elements made of steel, such as wires, Strands or the like and suitable for performing this method Anchoring devices.
- a freely tensioned tension member for example a stay cable for a Cable-stayed bridge, an external tendon or the like from a bundle of plastic-coated individual elements made of steel, such as wires, Strands or the like and suitable for performing this method Anchoring devices.
- Tension members such as those used in construction to anchor components, for example as Cable-stayed cables for cable-stayed bridges, as external tendons or similar Tension elements are used, often consist of a bundle of Individual elements, such as steel wires or strands, in the free area the tension member arranged together in a tubular envelope through which passed components and at their entry point opposite side are anchored by means of anchoring devices.
- These anchoring devices usually consist of one armature disk each with holes through which the individual elements are inserted.
- the Holes initially have a cylindrical, then a conical one Area in which the individual elements are anchored by means of multi-part ring wedges.
- the tubular casing of the tension member can be made in its free area a plastic pipe, for example made of polyethylene (PE), or from a Steel tube exist; in the anchoring area it usually consists of one Steel anchor tube.
- PE polyethylene
- Steel wire strands are often used as individual elements for such tension members used for corrosion protection with a grease coating and a coating made of plastic, usually made of PE.
- This casing can be extruded be tight, i.e. in the form of an envelope tube, a so-called PE jacket of the strand and move with it when the strand is tensioned, or it can surround the strand as a tube with a certain distance; in this In this case, the strand is pulled out of the sheath during tensioning.
- PE-coated strands can be used in the same way as bare strands without sheathing, it is in any case necessary to pass the strands through Remove the PE jacket in the area of the anchorages to expose the ring wedges used for anchoring directly on the metallic Can attack the surface of the strands.
- the ends of the strands intended for anchoring are often already in front of them Installation in the relevant structure exposed by removing the PE jacket. It is often difficult to exactly increase the length before installing the strands determine the PE sheath over which the strands must be removed to anchor properly. The exposed length turns out to be too in short, the reliability of the anchorage can be questioned; is the exposed length too long, then the reliability of the Corrosion protection may be at risk.
- the invention has for its object a simpler and less expensive way to find the PE jacket in the area of To remove the exciting part of a strand or the strand in this area to expose that the remaining PE jacket in the final state as close as possible to the Anchoring area of the strand ends.
- the basic idea of the invention is one of the individual elements Tension member closely fitting surrounding plastic jacket at the end where the individual elements are tensioned and anchored, not over their entire length to remove the stretching that occurs when tensioning, but rather when Tensioning the individual elements, which is a longitudinal movement in the anchoring area caused to prevent just this longitudinal movement, whereby he, as far as he the Longitudinal movement of the strand follows during tensioning, in the pre-anchoring lying area is compressed.
- the plastic jacket suffers from this compression a deformation initially in the elastic range, but then at least partly changes into plastic deformation.
- a first way is to get into the Bores of the armature disk, namely in its cylindrical part, a pressure pipe insert that closely surrounds a single element and that on its one End forms a stop for the face of the plastic jacket while it is on the opposite side to the anchoring wedge, namely on its slim end.
- the extent of the possible compression of the plastic jacket is from the Properties of the material, temperature and other influencing factors dependent. Therefore it can be useful, especially for larger ones Tension paths, the end of the strand at which this is tensioned and anchored, to reveal a certain area beforehand, be it by removing the Plastic jacket before installation, either by peeling off the jacket during the clamping process, and by the invention Upsetting just fine-tune to the end of the Plastic jacket and thus the corrosion protection as close as possible to the Bring or connect anchoring device.
- the 1 and 2 is an anchoring area of a bundle tendon 1, for Example of a stay cable of a stay cable bridge, from a number of single ones Tension elements 2 shown.
- the individual elements 2 consist of steel wire strands 3, each for corrosion protection with a tight-fitting covering Plastic, for example PE, a so-called PE jacket 4, are provided; the The cavity between each strand 3 and the PE jacket 4 is plastic deformable anti-corrosive compound, for example grease.
- the strands 3 are each by means of multi-part ring wedges 5 in the conical part of Bores 6 anchored in an armature disk 7.
- the armature disk 7 has a External thread and is surrounded by a ring nut 8, which has a corresponding Has internal thread and is supported against an anchoring body 9, the abuts on a building component, for example a concrete component 10, or in this is embedded.
- the bundle tendon 1 following the Tubular casing surrounding the anchoring area is indicated at 11.
- An anchor tube 12 is attached to the armature disk 7 toward the concrete component 10, for example welded on. Within this anchor tube 12 is located on the Armature disk 7 then a seal from one or more Sealing plates 13. A spacer 14 is excluded from the plates 13 Plastic, on which in turn abuts a pressure plate 15 made of steel. Both the Sealing plates 13 as well as the spacer 14 and the pressure plate 15 have aligned holes with the holes 6 of the armature plate, the the individual elements 2 are interspersed.
- the anchor head formed in this way is penetrated by threaded bolts 16, by tensing them from the air side forth pressure can be exerted on the sealing plates 13, so that these in get into a three-dimensional state of tension and a reliable one Represent seal against the individual elements 2 penetrating them.
- the entire anchor head is closed to the air side by a cap 17 in which are injected through an injection opening 18 corrosion protection material 19 can.
- FIG. 3 shows the anchoring area on a larger scale as a detail from FIG. 1 of a single element 2 in a bore 6.
- the single element 2 is shown as steel wire for simplicity; in practice it usually does a strand 3 made of steel wires, which is why this expression below will be needed.
- the bore 6 is divided into an upper conical, the ring wedge 5 receiving area 6a and a lower cylindrical area 6b.
- a pressure tube 20 is located in the lower cylindrical region 6b of the bore 6 used, the inner diameter of the outer diameter of the strand 3 and whose outer diameter is the inner diameter of the cylindrical part 6b Correspond to hole 6.
- the lower end 20a of the pressure tube 20 forms a shoulder as a stop for the front end of the PE jacket 4; the top end 20b lies on the lower, slender end 20a of the ring wedge 5 and finds an abutment on this.
- Fig. 4 shows a second embodiment of such a device for Prevent axial movement of the PE jacket 4.
- a blind hole-like extension 6c which is an annular shoulder at the transition to the cylindrical region 6b 6d forms. If the diameter of the cylindrical portion 6b is only so large, that the strand 3 can just pass through, the strand 3 finds in its rest Area closely fitting surrounding PE jacket 4 on this shoulder 6d Stop, which also prevents him from longitudinal displacement when the wire 3 stretching during tensioning and consequent longitudinal movement through the Armature disc 7 experiences.
- Figs. 5 and 6 in similar representations as shown in FIGS. 2 and 3.
- Fig. 5 shows the state during tensioning
- Fig. 6 the tense and anchored condition.
- the attachment head 21 a - not shown - Clamping press, which is supported on the top 7b of the armature disk 7 Stamp 22 arranged with a lower flange 23 opposite air-side thicker end 5b of the wedge 5 is supported.
- the has in the side wall Attachment head 21 has a recess 24 in which a clamping screw 25 can be moved is that can be screwed into a transverse bore in the punch 22.
- the longitudinal movement of the ring wedge 5 when tensioning the strand 3 in Direction of arrow 26 is limited by the fact that the thicker end 5b of the air side Ring wedge 5 finds a stop on the flange 23 of the punch 22, which in turn rests on a shoulder 27 inside the attachment head 21. Thereby the wedge 5 is prevented from opening too wide.
