SOCKET FASTENING-TYPE REINFORCING BAR CONNECTOR USING BINDING END MEMBER

摘要

The present invention relates to a socket fastening-type reinforcing bar connector using a binding end member and, more particularly, a reinforcing bar connector is disclosed wherein binding end members are bound to reinforcing bars, in order to facilitate processes for joining reinforcing bars, which are the foundation of reinforced concrete, and processes for joining between reinforcing bar cages, such that reinforcing bars having adjacent ends can be precisely connected mechanically through simple socket fastening.

1. A socket-fastening-type reinforcing bar connector using a binding end member comprising:
a first reinforcing bar and a second reinforcing bar abutting each other while having end portions facing each other; a first binding end member bound to the end portion of the first reinforcing bar and having a male screw portion for coupling a fastening socket formed in the longitudinal direction at an outer surface thereof; a second binding end member having one end portion formed of a shape corresponding to a shape of an end portion of the first binding end member and the other end portion bound to the end portion of the second reinforcing bar and spaced apart from the one end portion, and having one or a plurality of steps with one end portion in the axial direction forming any one angle selected from an acute angle, a right angle, and an obtuse angle with respect to the longitudinal direction; and a hollow fastening socket opened in the longitudinal direction to extend in the longitudinal direction to surround and accommodate an outer surface of the second binding end member and an outer surface of the first binding end member, having a female screw portion for coupling a fastening socket that is helically coupled to the male screw portion for coupling a fastening socket of the first binding end member formed in the longitudinal direction at an inner surface thereof, locked to the one or the plurality of steps of the second binding end member, and having one or a plurality of locking steps forming any one angle selected from an acute angle, a right angle, and an obtuse angle with respect to the longitudinal direction, wherein the fastening socket is moved forward toward the first binding end member and rotated in a fastening tightening screw direction such that locking steps of the fastening socket are tightly supported by the second binding end member to allow the first binding end member and the second binding end member to be integrally fastened by the fastening socket in order to mechanically join the first reinforcing bar and the second reinforcing bar, a shape of the first binding end member bound to the end portion of the first reinforcing bar is a shape in which one end portion is a bar material shape having a width equal or similar to that of the first reinforcing bar and a transverse cross-sectional surface formed in a circular shape in order to have a structure joined to the first reinforcing bar and the other end portion is a bar material shape having a more extended width than the bar material shape of the one end portion and having the male screw portion for coupling a fastening socket formed at the extended outer surface to have a width that is a sum of an extended bar material shape of the second binding end member and a height of a screw thread in order to be a bar material shape extended by the width being stepped near the end portion in the longitudinal direction, a shape of the second binding end member bound to the end portion of the second reinforcing bar is a shape in which one end portion is a bar material shape having a width equal or similar to that of the second reinforcing bar and a transverse cross-sectional surface formed in a circular shape in order to have a structure joined to the second reinforcing bar and the other end portion is a bar material shape having a more extended width than the bar material shape of the one end portion but being formed in a smaller width than an inner surface of the fastening socket to allow the fastening socket to move at an outer surface and having a step in a form of a protruding band that surrounds the outer surface to be extended by the width being stepped near the step, the step in the form of a protruding band is in the shape of a protruding band surrounding from a portion near the bar material shape in which the width of the second binding end member is extended up to an end surface of the second binding end member or forms a shape of a protruding band that surrounds the portion near the bar material shape in which the width of the second binding end member is extended while having a shortened width, the inner surface of the fastening socket is a cylindrical shape having a circumference to be rotatable in the fastening tightening screw direction while having the longitudinal direction as an axis in order to surround the bar material shape in which the width of the second binding end member is extended and be movably coupled to the outer surface of the second binding end member, and a locking step protruding in a central direction in the shape of a protruding band is included at an opposite end portion of the female screw portion for coupling the fastening socket of the inner surface of the fastening socket to be locked to the one or the plurality of steps of the second binding end member, and the female screw portion for coupling the fastening socket is formed at a portion near the end portion in the first binding end member direction at the inner surface of the fastening socket such that the fastening socket formed to surround the bar material shape in which the width of the second binding end member is extended and the bar material shape in which the width of the first binding end member is extended is helically fastened to the male screw portion for coupling the fastening socket of the bar material shape in which the width of the first binding end member is extended and the locking step and the step in the shape of the protruding band tightly support each other at the same time to allow the end portion of the extended bar material shape of the first binding end member at which the male screw portion for coupling the fastening socket is formed and the end portion of the extended bar material shape of the second binding end member to be integrally coupled while supporting and facing each other.
