Abstract

''DISPOSITIVO DE FLUTUAçãO'', para ser fixado ao redor de pelo menos um elemento longitudinal (8). O dispositivo de flutuação (1) compreende um dispositivo de sujeição montado (2, 3, 4, 5, 6, 7) que é para ser fixado ao redor do elemento (8) e pelo menos um membro flutuador (9, 10) conectado ao dispositivo de sujeição (2, 3, 4, 5, 6, 7). O membro flutuador (9, 10) está dividido longitudinalmente em, pelo menos, duas seções e esta disposto ao redor do elemento (8), juntamente com o dispositivo de sujeição (2, 3, 4, 5, 6, 7). O membro flutuador (9, 10) está dividido em, pelo menos, dois segmentos flutuadores (9, 10) pivotados em conjunto ou separadamente, os quais podem ser colocados ao redor do(s) elemento(s) 8 e folgadamente envolvem uma parte do(s) mesmo(s). O dispositivo de sujeição (2, 3, 4, 5, 6, 7) está dividido em, pelo menos dois segmentos de sujeição (11, 12) separados ou articulados em conjunto, adaptados para serem colocados ao redor do elemento(s) 8, preferência de uma maneira firme de pré-tensionada. Os segmentos flutuadores (9, 10) estão mecanicamente inter-conectados por, pelo menos, um dos segmentos de sujeição (11, 12) por meio de partes complementares e que se estendem radialmente (16, 4) do segmento flutuador (9, 10) e do segmento de sujeição (11, 12), respectivamente, de forma que os segmentos de sujeição (11, 12) e os segmentos (9, 10) são conectados a um dispositivo de flutuação (1) por meio de, pelo menos, um elemento de tensão periféricos (5) que é deslizantemente fixado a pontos de sujeição (3), o mais distante das partes que se estendem radialmente dos segmentos de sujieção (11, 12), sem desgastar os membros flutuadores (9, 10).
