Definitions

  • the invention is based on anchoring free-swinging steel tensile elements of a dynamically stressed component, which tensile elements are deflected twice in the anchoring area, with an anchor body with bores running parallel to one another, through which the tensile elements are guided and conical at their ends are anchored to the outward-opening spaces of the bores by means of clamping wedges, support means being provided to absorb deflection forces in the deflection area of the anchor body, against which the tension elements bear, and with an expansion ring for bundling the tension elements emerging from the anchor body holes and passing through the expansion ring.
  • CH-PS 541 693 tries to eliminate these disadvantages.
  • support means are inserted into the deflection area of the armature body, against which the wires rest.
  • these support means center the wires relative to the anchor body in a predetermined position.
  • the support means are inserted in the spaces between the wires and the respective bore wall and fill these spaces.
  • the support means consist of a material that is softer than the material of the wires and / or the anchor body. With this measure, the friction at the deflection points of the wires is reduced in order to largely avoid breakage of friction and corrosion. The friction and the
  • the most commonly used solution consists in filling the anchoring area in a force-fitting manner with rods, wires or strands of a suspension cable.
  • potting anchoring is discussed in DE-OS 26 14 821.
  • a casting compound made of fine zinc or zinc alloys is provided, which has properties that prevent fretting corrosion.
  • the function of such backfilling is to gradually remove the force of the rods, wires or strands so that they no longer reach the deflection point on the support plate, or are weakened in a harmless manner. This measure in no way increases the vibration resistance of the rods, the wires or the strands.
  • the anchorages described in the last two publications relate only to the deflecting forces which arise in the region of an anchor body or a support plate and in no way solve problems caused by those acting on the second deflecting point Deflection forces, where the individual tension elements are bundled into one link, are caused.
  • the object of the invention specified in patent claim 1 was to provide anchoring of freely oscillating tension elements made of steel of a dynamically stressed component, which makes it possible that the tension elements passing through the bores of the anchor body are not exposed to any friction, whereby the force is transmitted to the clamps by means of which the tension elements are anchored in the bores of the anchor body.
  • the deflection forces at the first deflection point are thus to be eliminated.
  • the deflection forces at the second deflection point, where the tension elements converge to form a bundle are also to be eliminated.
  • the object is achieved with an anchoring according to the preamble of claim 1 by the features of the characterizing part of claim 1.
  • the diameter of each hole is advantageously 2 to 5 mm larger than that of the tension elements.
  • 1 is a view, partly in longitudinal section, of an anchoring with twice deflected tension elements.
  • FIG. 2 shows a partial longitudinal section of another embodiment of the anchoring on a larger scale, in which only the anchor body is shown with a tension element
  • FIG. 3 shows a side view of a perforated, elastically flexible washer according to FIG. 1,
  • FIG. 4 shows a partial longitudinal section of a still further embodiment, in which the anchor body is partially shown only with a bore and a tension element carried through it, and
  • Fig. 5 shows a partial longitudinal section of yet another
  • B. is a free-swinging suspension cable of a cable-stayed bridge, is fanned out on its end to be anchored in individual traction elements 4 (rods, wires or licens).
  • the part of the tension member to be anchored is arranged in a tubular guide sleeve 8.
  • the guide sleeve 8 can consist of plastic or sheet steel and is intended for concreting.
  • the end parts of the tension elements 4 are carried out through mutually parallel bores 2 of an anchor body 1. With the anchor body 1, a clamping ring 7 is screwed, which in turn is welded to the guide sleeve 8.
  • the anchor body 1 is usually made of steel.
  • the bores 2 have conically opening spaces 2a, into which clamping wedges 3 are inserted, by means of which the end parts of the tension elements 4 are anchored to the anchor body 1.
  • the diameter D of each bore 2 in its section 2c, which extends from the conically opening space 2a to approximately to the outlet end 2b, is constant and larger than that d_ of the tension element 4.
  • the diameter D of each bore 2 is around 2 to 5 mm larger than that d of the tension elements 4.
  • oscillatable support means made of a material that is softer than the material of the anchor body 1 or the tension elements 4 lying against the support means 4 are provided.
  • the support means are only provided in the area of the outlet ends 2b.
  • the support means can, as can be seen from the figures, consist of one each, in a circular recess 11 in the wall of the
  • the elastically flexible ring 5, 13, 14 exist, which resonates with the tension element 4.
  • the rings 5, 13, 14 are advantageously glued to the wall of the circular recess 11.
  • the elastically flexible ring 5, 13, 14 can have the shape of a polygon, trapezoid or a circle.
  • the support means can consist of a perforated, resiliently flexible disk 6 which is held on the anchor body 1 by means of the clamping ring 7 on the exit side of the bores 2, abutting the end face of the anchor body.
  • the holes 12 of the disk 6 are aligned with the bores 2 of the anchor body 1, so that the tension elements 4 emerging from the anchor body bores 2 pass through the holes 12.
  • the perforated edges of the disk 6 lie closely against the tension elements 4. The disc 6 thus vibrates with the tension elements 4 passing through its holes 12.
  • Tension elements act as deflection forces.
  • the expansion ring has an insert 10 resting on the tension elements 4 on its surface facing the tension elements 4.
  • the material of the insert 10 is softer than that of the expansion ring 9 or the tension elements 4.

Abstract

Les éléments de traction (4) d'un tirant en acier sont ancrés à leurs extrémités au moyen de coins de serrage (3) dans des perçages (2) parallèles d'un corps d'ancrage (1). Le diamètre (D) de chaque perçage (2) dans sa section (2c) est constant et plus grand que le diamètre (d) de l'élément de traction (4). On a prévu dans le corps d'ancrage (1) à l'endroit où les éléments de traction changent de direction un anneau (5) souple élastique absorbant les forces de déviation. Cet anneau (5) est logé dans un évidement circulaire (11) de la paroi de sortie (2b) de chaque perçage (2). Dans la zone de changement de direction de l'anneau d'écartement (9), à l'endroit où les éléments de traction forment un faisceau, on a prévu une garniture (10) en matière plus tendre que celle de l'anneau d'écartement (9) ou des éléments de traction (4). De même la matière de l'anneau (5) est plus tendre que celle du corps d'ancrage (1) ou des éléments de traction (4). Par ces dispositions on éliminera les forces dues aux déviations des éléments de traction (4) agissant sur ces derniers aussi bien au premier qu'au second endroit de changement de direction.
