Definitions

  • Gelak ABSTRACT A wire cable anchoring arrangement for high dynamic loads in which the individual wires of the cable are guided through bores of a common anchoring body and anchored at their ends thereat. For the purpose of taking-up deflection forces there are provided support means against which bear the wires and which retain the wires in a predetermined position relative to the anchoring body.
  • the present invention relates to a new and improved wire cable or stranded cable anchoring arrangement for high dynamic loads wherein the individual wires of the cable are guided through bores of a common anchoring body and anchored thereat at their ends.
  • end anchoring for the individual wires there can be employed a wire end which has been upset into a conical head and which additionally enables attaching the individual wires of a bundle at a common steel anchoring body with the smallest intermediate spacing.
  • the wires extend into parallel bores provided at the anchoring body.
  • the anchoring body is only as long as required by the static conditions; it can possess for instance an external threading and be supported by means of a nut member against the carrier or support construction, or it can have a widened external diameter and bear upon the thus provided annular or ring-shaped surface.
  • Anchoring arrangements for anchoring wire bundles in the previously described manner are well known to the art and have been successfully employed in particular in stressed concrete. Yet, if it is desired to employ such anchoring arrangements for freely exposed supporting or 'carrier cables which are subjected to the aforementioned extremely high dynamic oscillation loads, for instance at diagonal suspension cable bridges, then it is necessary to carry out a number of extemely important measures, and particularly as concerns the arising deflection forces, the corrosion problems and similar problems.
  • the bundle of wires of a freely exposed wire cable should be grouped as tighly and closely together as possible at the departure location from the anchoring body, and in a manner wherein the individual wires can contact one another.
  • the wires in the bores of the anchoring body and through which the wires extend contact the walls of such bores in the direction of the axis of the bundle of wires and can form a kink or bend during depature out of the anchoring body.
  • the wire bundle must be slightly twisted or rotated (for instance if it should be rolled-up for reasons of transport); also as a result thereof the wires upon leaving the anchoring body can be deflected such that they come to bear against the walls of the bores. It has been found that such contacting and bending or kinking of the wires results in a considerable reduction in the oscillation strength of such anchoring.
  • Another and more specific object of the present invention relates to an improved construction of wire cable anchoring arrangement which reliably and effectively fulfills the requirements imposed thereon and avoids the heretofore known drawbacks.
  • the inventive wire cable anchoring arrangement for high dynamic loads and wherein the individual wires of the cable are guided through bores of a common anchoring body and anchored at their ends thereat is manifested by the features that for the purpose of taking-up the deflection forces there are provided support means against which bear the wires and which retain the wires in a predetermined position relative to the anchoring body.
  • the introduction of the support means can advantageously occur by insertion or embedding same or, in a particularly advantageous manner, by casting or molding thereof.
  • FIG. 1 is a longitudinal sectional view through a particularly simple constructional embodiment of inventive anchoring arrangement
  • FIG. 2 is a longitudinal sectional view through a finished anchoring arrangement wherein for the. purpose of improving the clarity in illustration there have only been shown a few of the wires in the anchoring body;
  • FIG. 3 is a front view of the conical end anchor, that is to say, the end or terminal heads of the spread apart or fanned wires which are anchored at the anchoring body;
  • FIG. 4 is a sectional view through the bundle of wires which has been tightly grouped together at a close spacing by the anchoring arrangement.
  • FIG. 1 illustrates an anchoring arrangement possessing a particularly simple construction.
  • the ends of the individual wires 1, 1", 1", etc. ofa cable that is to say, a bundle or bunch I of such wires forming a cable, extends in a slightly fanned apart or spread condition through essentially parallel bores 2, 2", 2" etc. of a common anchoring body 2 formed of steel.
  • the individual wires 1, l", 1" etc. possess at their ends upset heads 3, 3", 3" etc. respectively, by means of which these wires are anchored at the anchoring body 2.
  • sup porting cushions 2a, 2b, etc. which absorb or takeup the deflection forces and retain the wires in a'predetermined position with respect to the anchoring body 2, for instance guide the wires in a centered or parallel position with respect to the axis of the wire bunch or bundle 1.
  • the support cushions 2a, 2b, 20, etc. consist of support or supporting bodies formed of a material which is softer than that of the wires 1', 1", 1' etc. or anchoring body 2.
  • the support bodies are introduced into the spaces between the wires 1', l", 1" etc. and the walls of the associated bores 2a, 2b, 20, etc. and fill out such spaces. In this way there is not only attained the desired supporting function but simultaneously also protection against corrosion effects.
  • the supporting bodies 2a, 2b, 20, etc. preferably consist of plastic, for instance, epoxy-, polyamideor polyacetal resins and are advantageously formed in situ by casting appropriately hardening masses.
  • FIG. 2 of the drawing depicts a sectional view through a different inventive embodiment of wire cable anchoring arrangement, that is to say, an anchoring for the ends of the spread apart or fanned individual wires 1', 1", l etc. of a wire bundle or bunch I.
  • the individual wires 1', 1", l etc. of the cable or rope likewise extend through parallel bores 2, 2", 2" etc. respectively of a common anchoring body 2 formed of steel.
  • the individual wires are provided at their ends with upset heads 3', 3", 3 etc. respectively, by means of which the wires can be anchored at the anchoring body 2.
  • the depicted anchoring body 2 possesses external threading 4 upon which there is threaded a nut member 5.
  • This nut member 5 bears against a carrier or support construction 6.
  • the nut member 5 there could be employed a part of the anchoring body itself, as same has been depicted for instance-in the arrangement in FIG. 1, and the anchoring body 2 therefore would bear directly against the support construction 6.
  • a guide disk unit 7 is non-displaceably connected with the anchoring body 2.
  • This guide disk or guide disk unit 7 is constructed as a double disk arrangement consisting of the two disks 7 and 7".
  • the guide disk unit 7 consists of plastic or a metal which is soft in contrast to the wire material, for instance formed of aluminum or cast iron.
  • the guide disk 7 is arranged at a slight spacing from the actual anchoring part or component, that is, the central portion 8 of the anchoring body 2 and serves as a boundary or stop, in other words as a type of cover during the fabrication of the hereinafter to be described support body for the individual wires 1', l", I" etc. of the bundle 1.
  • such guide disk unit 7 is provided with perforations or holes 7a corresponding to the bores 2, 2", 2" etc.
  • a support body 9 at the deflectionor kinking region of the wires. that is to say, at and in the region of their departure from the bores 2', 2", 2" etc. of the anchoring body 2.
  • this support body 9 is located in the space between the guide disk unit 7 and the central portion 8 of the anchoring body 2.
  • the support body 9 consists of a hardened plastic mass, for instance epoxy resin which is injected through the lateral bore 10.
  • the individual wires 1', 1", 1" etc. bear against the support body 9 and are thus retained in a predetermined position relative to the anchoring body; the wires are not pressed against the walls of the bores.
  • the hardened mass of the support or supporting body 9 also extends into thespaces between the wires l', l, l" etc. and the walls of the bores 2, 2", 2" etc. and even passes such and therefore forms an ideal corrosion protection for these wires and the heads thereof.
  • the space which is closed 'by the cover member 11 is provided with at least one vent or aeration opening 12.
  • this new and improved construction of anchoring arrangement fulfills all of the requirements placed thereon and attains a strength which could never be realized or in fact was even inconceivable with the heretofore known anchoring constructions.
  • the support body also could be formed of a different material. Instead of being cast or molded it also could be embedded or inserted. Suitable as the materials for forming the support body are those which are softer in comparison with the material of the wires. Particularly suitable are hardened casting masses since casting or molding of the support body has been found to be particularly advantageous and economical. In the case of support bodies which are fabricated in situ, that is to say, in the case of cast support bodies there is not only solved the problem of taking-up the deflection forces but also at the same time that of protecting against corrosion effects.
  • the guideand closure disk unit 7 is particularly advantageous (with a cast supporting body) this disk 7 of course also could be dispensed with.
  • Wire cable anchoring arrangement for high dynamic loads, comprising a common anchoring body having bores therethrough, individual wires of a cable guided through said bores and anchored at their ends at said anchoring body, a supporting body of material softer than the wires provided at least at a wire outlet section of the bores of the anchoring body at a respective space between the wires and the walls of said bores, said supporting body bearing at the anchoring body and at the wires for taking-up the deflection forces to which the wires are exposed and for retaining the wires in a predetermined position relative to the anchoring body, and guide disk means disposed behind said anchoring body provided with perforations corresponding to the bores of the anchoring body wherein the guide disk means consists of a double disk arrangement and a sealing material arranged between both of the disks of the double disk arrangement.
  • Wire cable anchoring arrangement for high dynamic loads, comprising a common anchoring body having bores therethrough, individual wires of a cable guided through said bores and anchored at their ends at said anchoring body, two spaced disks disposed at a distance behind said anchoring body provided with perforations corresponding to the bores of the anchoring body, a sealing material in the space between said disks, and a supporting body comprising material softer than'the wires located in the space between said disks and the anchoring body and extending into said bores between the wires and the walls of said bores, said supporting body bearing at the anchoring body and at the wires and adapted to take-up the deflection forces to which the wires are exposed and to retain the wires in a predetermined position relative to the anchoring body.
