Abstract: front page image
(EN)The present invention relates to a high strength one-touch type reinforcing bar coupler in which elastically deformable variable guides are installed between a plurality of locking segments, thereby being capable of accommodating and grasping reinforcing bars having various rib shapes, and stably grasping reinforcing bars without causing necking or rupture of the reinforcing bars even when a strong tensile strength is applied to the reinforcing bars. The high strength one-touch type reinforcing bar coupler according to the present invention comprises: a sleeve which is formed so that both ends thereof are opened, and which has formed therein a hollow part in an inlet part for inserting reinforcing bars therethrough, the hollow part having a tapered part of which the inner diameter gradually increases axially inwardly; a base member which is installed on the inner side of the hollow part of the sleeve; a plurality of locking segments which are installed on the inner side of the hollow part of the sleeve, and which are formed such that the outer surface thereof is inclined at an angle corresponding to the tapered part of the sleeve and connected to the tapered part, and the inner surface thereof has formed thereon a plurality of locking protrusions by which joints of the reinforcing bars are caught and supported; an elastic member which is installed between the locking segments and the base member to apply an elastic force to the locking segments axially outwardly relative to the base member; and a plurality of variable guides which are formed to be fixed to the base member and which are arranged between the locking segments and elastically deformed in response to changes in the spaces between the locking segments.
(FR)La présente invention concerne un dispositif d'accouplement de barre de renfort de type à un seul mouvement à haute résistance dans lequel des guides variables élastiquement déformables sont installés entre une pluralité de segments de verrouillage, étant ainsi capables de recevoir et de saisir des barres de renfort possédant diverses formes de nervure, et de saisir de façon stable les barres de renfort sans provoquer de resserrement ou de rupture des barres de renfort même lorsqu'une charge importante de traction est appliquée aux barres de renfort. Le dispositif d'accouplement de barre de renfort de type à un seul mouvement à haute résistance selon la présente invention comprend : un manchon qui est formé de sorte que l'une et l'autre de ses extrémités sont ouvertes, et dans lequel est formée une partie creuse dans une partie d'entrée, destinée à l'insertion de barres de renfort à travers celle-ci, la partie creuse possédant une partie effilée dont le diamètre interne augmente progressivement en sens axial vers l'intérieur ; un élément de base qui est installé sur la face intérieure de la partie creuse du manchon ; une pluralité de segments de verrouillage qui sont installés sur la face intérieure de la partie creuse du manchon, et qui sont formés de telle sorte que leur surface externe est inclinée selon un angle correspondant à la partie effilée du manchon et reliée à la partie effilée et, sur la surface interne de ceux-ci est formée une pluralité de saillies de verrouillage permettant de saisir et de soutenir les joints des barres de renfort ; un élément élastique qui est installé entre les segments de verrouillage et l'élément de base pour appliquer une force élastique aux segments de verrouillage en sens axial vers l'extérieur par rapport à l'élément de base ; et une pluralité de guides variables qui sont formés pour être fixés à l'élément de base et qui sont disposés entre les segments de verrouillage et déformés élastiquement en réponse à des changements dans les espaces entre les segments de verrouillage.
(KO)본 발명은 복수개의 록킹편체의 사이에 탄성 변형이 가능한 가변형 가이드를 설치하여 다양한 형태의 리브를 가진 철근을 수용하여 파지할 수 있으며, 철근에 강한 인장력이 가해지더라도 철근의 네킹 현상이나 파단이 발생하지 않고 철근을 안정적으로 파지할 수 있는 고강도 원터치식 철근 커플러에 관한 것으로, 본 발명에 따른 고강도 원터치식 철근 커플러는, 양단부가 개방되게 형성되되, 철근이 삽입되는 입구 부분에 축방향 내측으로 갈수록 점진적으로 내경이 커지는 테이퍼부를 갖는 중공부가 형성된 슬리브와; 상기 슬리브의 중공부 내측에 설치되는 베이스부재와; 상기 슬리브의 중공부 내측에 설치되며, 외면이 상기 슬리브의 테이퍼부와 대응하는 각도로 경사지게 형성되어 테이퍼부와 연접하고, 내면에 철근의 마디가 걸리면서 지지되는 복수개의 록킹돌기가 형성되어 있는 복수개의 록킹편체와; 상기 록킹편체와 베이스부재 사이에 설치되어 베이스부재에 대해 록킹편체에 축방향 외측으로 탄성력을 부여하는 탄성부재와; 상기 베이스부재에 고정되게 설치되며, 상기 록킹편체의 사이사이에 배치되어 록킹편체 간의 간격 변화에 대응하여 탄성 변형되는 복수개의 가변형 가이드를 포함하는 것을 특징으로 한다.
