Abstract

La présente invention concerne une barre d'armature composite de type tissé et un procédé pour sa fabrication. La barre d'armature composite de type tissé comprend une paire de tubes d'alimentation côté gauche et de tubes d'alimentation côté droit disposés verticalement respectivement dans des parties supérieures des côtés gauche et droit d'un noyau en forme de barre ronde qui est posé en travers horizontalement, une première mèche de fibres passant à travers la paire de tubes d'alimentation côté gauche et formant une forme convexe vers le bas, et une seconde mèche de fibres passant à travers la paire de tubes d'alimentation côté droit et formant une forme convexe vers le bas. Plus particulièrement, la présente invention concerne une barre d'armature composite de type tissé et son procédé de fabrication, la barre d'armature étant caractérisée en ce qu'elle est fabriquée par un procédé de fabrication de barre d'armature composite de type tissé comprenant : une première étape consistant à abaisser les tubes d'alimentation côté gauche et les tubes d'alimentation côté droit de telle sorte que les parties d'extrémité de la première mèche de fibres et de la seconde mèche de fibres sont positionnées sous le noyau ; une seconde étape consistant à nouer les parties d'extrémité de la première mèche de fibres et de la seconde mèche de fibres, qui sont positionnées sous le noyau, pour former un nœud inférieur du noyau ; une troisième étape consistant à soulever les tubes d'alimentation côté gauche et les tubes d'alimentation côté droit ; et une quatrième étape consistant à faire tourner les tubes d'alimentation côté gauche et les tubes d'alimentation côté droit de 180° pour former un nœud en forme de X au-dessus du noyau. La barre d'armature composite de la présente invention présente une excellente durabilité ainsi qu'une résistance de liaison et une résistance à la traction améliorées, et ainsi un phénomène de dégradation dans lequel la barre d'armature composite se sépare d'une structure en béton peut être réduit. En outre, des nervures sont formées sur la circonférence extérieure du noyau d'une manière similaire au tissage d'une fibre, et il y a donc des effets significatifs, tels qu'une facilité de fabrication.
