摘要:
A termination for an end of a braid formed as a flat closed loop of braided strands expandable to an annular cylinder having a selected wall thickness includes a sleeve having a selected internal diameter. Spacers are configured to be applied on the braid such that when in contact with each other form an annular cylinder having an external diameter selected to fit inside the sleeve. The spacers have a bevel at one longitudinal end. A substantially cylindrical insert has a bevel at one longitudinal end at substantially a same bevel angle as on the spacers. A diameter of the insert combined with twice the wall thickness of the braid is larger than an internal diameter the spacers. When axial tension is applied to the braid, the bevel on the insert with braid thereon laterally urges the spacers outward. The sleeve limits lateral outward movement of the spacers.

Shaped terminations for composite tension members, as well as methods for creating such shaped terminations. A shaped termination is consolidated into a solid mass that is substantially uniform in structure. Heat and pressure are used to shape and fuse the carbon fiber composite into geometries having favorable loading characteristics. This durably fixes the components of the tension member into an optimized arrangement for the intended loading configuration such that unequal stresses are minimized. Terminal geometry can be formed by re-forming existing material, or by adding additional material, which can comprise a thermoplastic composite material or other epoxy/resin composite, metal, tow, tape, mat, or other fibers, to the inside or outside of the tension member. The terminal may be machined and/or thermoformed before and/or after the addition of material.

An arrangement (1) for connecting an elongate element (2) used in particular for absorbing and/or transmitting tensile and/or torsional forces to a further component (3) comprises a force introduction element (4) with a side facing the further component (3) and a side facing away from the further component (3) and an encasing element (5) having a closed cross-section, said encasing element encasing the force introduction element (4) at least in some sections and projecting over the force introduction element (4) on its side which faces away from the further component (3). Projections (6) are provided on at least one section of the force introduction element (4) on its outer surface facing the encasing element (5), said projections penetrating the encasing element (5) at least partially. The encasing element (5) consists essentially of a fibre composite material the fibre structure of which is produced in a braiding or winding process, wherein the fibres contained in the fibre composite material lie in continuous form at least partially in the regions formed between the projections (6). The projections (6) are present in a dense, regular arrangement at least in one region of the force introduction element (4) and the ratio of the height of the projections (6) to the diameter of the projections (6) is greater than 1, preferably greater than 2, in particular 3 and more.

A connecting system which allows a standard rigging fixture to be connected to a synthetic cable termination by swaging. The cable termination is provided with a swaging sleeve. When the standard rigging fixture is placed next to the termination, this swaging sleeve is swaged over a portion of the standard rigging fixture in order to lock the standard rigging fixture to the termination. The provision of the swaging sleeve on the termination is accomplished using a variety of approaches, including forming the swaging sleeve as part of an anchor, providing a separate swaging sleeve attached by threads, and forming the anchor and swaging sleeve with two separate swaging operations.

A termination of a tension member (1) for use as a tension leg for a tension leg platform. The tension member (1) consists of a plurality of carbon fiber filaments gathered into one or more strands (2) in which the filaments run close together. Around the strands is provided a sheath. The bundles/strands (2) are spread apart in a transitional zone, and each bundle/strand is inserted into its respective hole (6) in a socket (4, 5), and is fixed in relation to the hole (6) by means of a hardenable mass.

A wire stop for use with a multi-strand steel cable for securing trees and poles includes an outer body with a tapered opening extending therethrough. The wire stop also includes a tapered inner body with a central bore extending therethrough for receiving a single strand of the multi-strand steel cable therein and is sized and configured to be received in and cooperate with the tapered opening in outer body. With this construction, the multi-strand steel cable can be partially unwound and a single strand threaded through the central bore in the tapered inner body and the remaining strands can be threaded between the inner body and the outer body.

A method of terminating a fiber rope utilizing a device of the type which has a housing member having a frusto-conical bore in which an end portion of the rope can be wedgedly retained. The end portion of the rope has a reinforcing device incorporated therein in order to increase the tensile load capacity of the rope end portion. The reinforcing device may include a fiber type material, a length of fiber rope or a resinous compound applied to the fibers of the rope end portion.

An improved termination for rope (2) in which ends of rope elements (4) are encapsulated in resinous material (6) to form a fiber-and-resinous-material composite-mixture plug (8) within a tapered cavity (16) that is divided by radial plates (36) into smaller segments (46) and is partially filled with a tapered body (32) to provide a constant cross-sectional area.
摘要:
A method of terminating wire ropes by swaging in the field with hand tools. At the factory, one end of termination (9) has been prepared with threads (13) and the opposing end has been drilled forming a hole the diameter of which is too small to fit a wire rope end (11) with a tapered locking plug (10) installed. At the factory the remaining metal is then swaged outward, forming the swaged out sleeve portion (12), to an inside diameter sufficient to allow insertion of wire rope end (11) with plug (10) installed. Out in the field, plug (10) is first inserted into wire rope end (11) over the center strand and under the outer strands. Assembled wire rope end (11) and plug (10) are now inserted into swaged out sleeve portion (12). Swaged out sleeve portion (12), with wire rope end (11) and plug (10) installed, is then swaged inward, with a hand tool, forming the inside walls into a taper that is coextensive with the plug's tapered portion (18). Wire rope end (11) is under compression between the inner wall of swaged in sleeve portion (21) and plug (10). Under tension loads, the wire rope strands grip plug (10) sufficiently to shift plug (10) axially inside swaged in sleeve portion (21) so that plug (10) compresses wire rope end (11) ever more tightly against swaged in sleeve portion (21) effectively locking wire rope end (11) and termination (9) together.

A cable termination arrangement includes a tapered socket body and a mating plug covered with a sleeve of malleable material. Cable strands are inserted and spread out inside of the socket. The plug and sleeve are pushed into the socket for forcing the strands into the sleeve. When a tensile force is applied to the cable, slippage between the cable and the socket is zero.
