Abstract

Patente de Invenção: <B>"TERMINAçãO DE UM ELEMENTO DE TENSãO PARA USO COMO UM TENDãO PARA UMA PLATAFORMA DE PERNA DE TENSãO"<D>. Uma terminação de um elemento de tensão (1), para uso como um tendão ou corda para uma plataforma de perna de tensão. O elemento de tensão (1) consiste em uma pluralidade de filamentos de fibra de carbono acumuladas em um ou mais fios (2), nos quais os filamentos deslocam-se um contra o outro. Um revestimento (3) é fornecido em torno dos fios. Cada fio (2) é terminado em um elemento de recepção (6) e o elemento de recepção (6) é suspenso em um recesso (12) em um elemento de suspensão (7). Os fios (1) são, sobre uma área, espalhados de um fio em feixe para uma disposição dos filamentos individuais estendendo-se afastados um do outro. Esta área de dispersão é mantida junta por um cone protetor (10) que impede a dispersão a partir do deslocamento para baixo do fio. Os filamentos individuais de fibra de carbono (2) são inseridos em cavidades respectivas (4) em um elemento de recepção (3) e preso no mesmo com uma substância solidificante (5). As cavidades no corpo de recepção (3) podem ser de passagem direta, ou elas podem ser sem saída. Além disso, as cavidades (4) podem ser de configurações diferentes, a partir de um furo de diâmetro uniforme, uma cavidade cónica voltada para cima e para baixo, ou uma cavidade gradualmente escalonada. Prendendo os filamentos de fibra de carbono nesta maneira, uma boa ancoragem de cada filamento individual é assegurado, bem como um ajuste longitudinal dos filamentos, que dá uma carga uniformemente distribuída sobre o fio (1), e que somente forças axiais principais são aplicadas nos filamentos de fibra de carbono individuais (2).Invention Patent: <B> "TERMINATION OF A VOLTAGE ELEMENT FOR USE AS A TENDON FOR A VOLTAGE LEG PLATFORM" <D>. A termination of a tension element (1), for use as a tendon or rope for a tension leg platform. The tension element (1) consists of a plurality of carbon fiber filaments accumulated in one or more strands (2), in which the filaments move against each other. A coating (3) is provided around the wires. Each wire (2) is terminated in a receiving element (6) and the receiving element (6) is suspended in a recess (12) in a suspension element (7). The strands (1) are spread over an area of a bundle strand for an arrangement of the individual filaments extending apart from each other. This dispersion area is held together by a protective cone (10) that prevents dispersion from moving down the wire. The individual carbon fiber filaments (2) are inserted into respective cavities (4) in a receiving element (3) and attached to it with a solidifying substance (5). The cavities in the receiving body (3) can be of direct passage, or they can be without exit. In addition, the cavities (4) can be of different configurations, from a hole of uniform diameter, a conical cavity facing up and down, or a cavity gradually staggered. By securing the carbon fiber filaments in this manner, good anchoring of each individual filament is ensured, as well as a longitudinal adjustment of the filaments, which gives a uniformly distributed load on the wire (1), and that only major axial forces are applied to the individual carbon fiber filaments (2).
