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 mutually parallel bores through which the tensile elements are guided and at their ends in conically outwardly opening spaces of the bores are anchored by means of clamping wedges, support means being provided in the deflection area of the anchor body to absorb deflection forces, against which the tension elements bear, and with an expansion ring for bundling the tension elements emerging from the anchor body bores and passing through the expansion ring (CH-A-4 30 135 ).
  • the most commonly used solution consists of filling the anchoring area in a force-fitting manner with rods, wires or strands of a suspension cable.
  • potting anchoring is discussed in DE-A-2614 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 weaken it 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 generated in the area of an anchor body or a support plate and in no way solve problems caused by deflecting forces acting on the second deflecting point, where the individual tension elements are bundled into one link.
  • the object of the invention is an anchoring of free-swinging steel tension elements of a dynamically stressed component, which enables the tension elements passing through the holes in the anchor body to be exposed to no friction, so that the tensile force is completely transmitted to the clamps with which the tension elements are anchored in the holes in the anchor body are.
  • 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.
  • the tension member shown made of steel of a dynamically stressed component which tension member z. B. is a free-hanging suspension cable of a cable-stayed bridge, is fanned out on its end to be anchored in individual tension elements 4 (rods, wires or strands).
  • the part of the tension member to be anchored is arranged in a tubular guide sleeve 8.
  • the guide sleeve 8 can be made 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, in 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 the outlet end 2b, is constant and larger than that d of the tension element 4.
  • the diameter D of each bore 2 is 2 to 5 mm larger than that 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 Consist of an elastically flexible ring 5, 13, 14, which is accommodated in a circular recess 11 in the wall of the outlet end 2b of each bore 2 and which oscillates with the tension element 4.
  • the rings 5, 13, 14 are advantageously glued to the wall of the circular recess 11.
  • the resilient ring 5, 13, 14 can have the shape of a polygon, a 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 outlet side of the bores 2, lying against 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 rings 5, 6, 13, 14, which are polygonal, trapezoidal or circular in cross-section the perforated edges of the disk 6 lie tightly against the tension elements 4.
  • the disc 6 vibrates with the tension elements 4 passing through its holes 12.
  • the expansion ring has an insert 10 lying 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.
  • the free space between the tension elements and the bore walls in the anchor body means that the tension elements are not subjected to any friction, the tensile force being transmitted 100% directly to the terminals.
  • the measures described above significantly increase the vibration resistance and thus the service life of the tension elements both in the first deflection point on the anchor body and in the second deflection point on the expansion ring.
