Definitions

  • ABSTRACT An apparatus for anchoring wires or stranded wires incorporating an anchor plate equipped with throughpassage bores for the wires or stranded wires, and clamping wedges associated with the anchor plate for anchoring the wires or stranded wires.
  • the throughpassage bores possess at one end a conical recess for receiving the clamping wedges and also have a subsequently merging cylindrical section.
  • Means are provided for applying the clamping wedges, during the mounting of the apparatus at the wires or stranded wires and during the tensioning thereof, against a pressin plate arranged in spaced relation from the anchor plate and which press-in plate is provided with holes or perforations for the throughpassage of the wires or stranded wires.
  • the applying means retains the clamping wedges out of the their effective clamping position.
  • the press-in plate after tensioning of the wires or stranded wires, is displaceable against the anchor plate for simultaneously and uniformly bringing the wedges into their clamping position.
  • the present invention relates to a new and improved construction of apparatus for anchoring wires or stranded wires, also referred to as strands, and which apparatus is of the type incorporating an anchor plate equipped with throughpassage bores or holes for the wires or strands and which plate has associated there with clamping wedges for anchoring the wires or strands, the throughpassage bores being provided at one end with a conical recess for the reception of the clamping wedges and with a subsequently merging cylindrical section.
  • an apparatus of the aforementioned type in a most simple and reliable manner in that there are provided means in order to apply the clamping wedges, during application of the apparatus at the wires or strands and during the stressing or tensioning thereof, against a press-in plate arranged at a spacing from the anchor plate and this press-in or pressing plate is provided with perforations or bores, for the throughpassage of the wires or strands, said applying means serving to retain the wedges out of their operable clamping position, and after tensioning of the wires or stranded wires the press-in plate is displaceable towards the anchor plate for simultaneously and uniformly bringing the wedges into their clamping position.
  • FIG. 1 schematically illustrates a finished prepared anchoring apparatus designed according to the teachings of the present invention incorporating an anchor plate, wedges, springs and press-in plate:
  • FIG. 4 illustrates a finished mounted anchoring apparatus after anchoring of the stranded wire or strands.
  • the thus prepared apparatus is now ready to be placed upon the bundle or bunch of stranded wires consisting of the individual strands or stranded wires 9.
  • the stranded wire bundle must protrude by an amount L out of the building component 11 which is to be pre-tensioned or pre-stressed, as best seen by referring to FIG. 2.
  • the anchoring apparatus is now fixed in suitable manner at the region of the end of the bundle of stranded wires and for instance one strand or stranded wire after the other is introduced through the bores 2a of the apparatus, such that the ends of the stranded wires depart by an amount I from the other side of the anchoring apparatus, as best seen by referring to FIG. 2. Since as above-described the clamping wedges 4 are retained out of their effectual or working position, the threading-in of the stranded wires 9 is very easy and can be undertaken quickly, particularly since there is only encountered a minimum of frictional resistance.
  • the anchoring apparatus can be easily and quickly displaced against the support plate 16 at the building component 11 until it rests at this location, and it is to be observed that at this time all of the wedges 4 are still not in their effectual wire clamping position.
  • a tensioning or stressing apparatus 17 is pushed over the tensioning head 13 and the anchoring apparatus and the tensioning nut 18 is screwed on to the tensioning head 13; the tensioning apparatus is suspended for instance at a suitable lifting tool and can be secured to the support plate 16 (FIG. 4.).
  • FIG. 4 demonstrates an apparatus 19 for the purpose of pressing the press-in plate 6 and thus the wedges 4 against the anchor plate 3.
  • This apparatus consists of a ring-shaped body 21 which possesses cams or dogs 22 which extend inwardly through openings 30 in the wall of part of the tensioning apparatus or press. These cams 22 can come to bear against the marginal edge of the press-in plate 6 in order to displace this plate 6 towards the anchor or anchoring plate 3.
  • the apparatus 19 can be actuated or moved, for instance through the agency of a hydraulic cylinder assembly 23.
  • An apparatus for anchoring wires or stranded wires equipped with an anchor plate having throughppassage bores for said wires or said stranded wires. and which plate has associated therewith clamping wedge means for anchoring the wires or stranded wires, each throughpassage bore possessing at one end a substantially conical recess for receiving the clamping wedge means and subsequently merging substantially cylindrical section, the improvement comprising means for applying the clamping wedge means.
