  • the reinforcing steel used as a framework in the construction of reinforced concrete structures is mainly composed of two rows of ribs that are symmetrically over the entire length in the longitudinal direction and the longitudinal direction in order to improve the adhesion stress with the concrete. Since the reinforcing bars are produced in a limited length for transport or work convenience, most of them are connected and used. There are various methods for connecting the deformed reinforcing bars.
  • the most widely used method is the double joint method, which overlaps the ends of two reinforcing bars and binds them with a binding line. This method is inferior in safety because the joint depends only on the reinforcing force of the reinforcing bars.
  • the gas pressure welding method which is pressurized with air, heat deformation occurs at the joints, causing secondary stresses, which makes the joints more vulnerable than the rebar base material.

  • the reinforcing bars are produced by maintaining the material properties similar to those of concrete and thermal expansion. Since the name of the reinforcing bar does not allow the overlapping method for rebar joints of D29 or more (29 mm in diameter), as described above, the reinforcing bar is connected by gas pressure welding or mechanical method. It is a joint method that changes the original material properties of reinforcing bars by secondary processing, and inevitably permits this connection method, and many rebar connectors that can be connected without changing the original material properties have been developed. .

Since it is formed larger than the node 11, when the two reinforcing bars (1, 1a) are fastened with the sleeve (4z), there is a lot of play between the sleeve (4z) and the reinforcing bars (1, 1a), the fastening is easy to loosen and slip occurs have.
  • the lock nut 5z is fastened to both ends of the sleeve 4z and the grout material is filled in the sleeve 4z to remove the play. Since the strength is only about 10% of the reinforcing bar, it cannot be secured. The pitch of the rebars (1, 1a) is long, so the angle of inclination of the thread is large. There is a problem of safety that 5z can be easily solved.
  • lock nuts 5z are not integrally coupled to the sleeve 4z and are provided as separate parts, it is difficult to manage the parts, and the lock nuts 5z are relatively small in size, so they are safe from falling during connection work.
