AI Technical Summary

Benefits of technology

The present invention provides a reinforcing bar connector using a binding end member that can be easily joined without the need for alignment of centers or screw threads. The connector allows for the efficient joining of reinforcing bars by integrating them with a simple element. The shape of the end portions of the binding end members allows for a natural fit between the bars, ensuring a tight connection. The invention also allows for the adjustment of the positions of the reinforcing bars to facilitate the joining process. Additionally, the use of threaded joint type reinforcing bars allows for a stable connection and the support of reinforcing bars that come in close contact with each other. The overall effect of the invention is to improve the construction efficiency and stability of reinforced structures.

Problems solved by technology

However, due to a difficulty of precisely aligning start points and end points of screw threads of end portions of the main reinforcing bars, the fastening work has to be performed strenuously and forcibly by repetitively lifting and placing the upper reinforcing bars, thus causing a problem.

That is, since separate fastening works with respect to each of the couplers are possible but a work of aligning screw threads is difficult in the work of fastening reinforcing bar cages which are a prefabricated reinforcing bar network, female screw threads of the couplers to be fastened are formed wider than male screw threads thereof to improve processability of screw coupling, thus causing a wide gap between the fastened screw threads of the couplers and making it impossible for the connection using the couplers to be sturdy.

However, in the reinforcing bar connector using a screw type sleeve, a method in which reinforcing bars are joined by couplers after male screw processing is necessarily performed at end portions of the reinforcing bars is used, but problems related to the method of performing the male screw processing at the end portions of the reinforcing bars are appearing, and some developed countries are already regulating and prohibiting the method of joining reinforcing bars by screwing end portions of the reinforcing bars.

However, in a process of performing swaging screw processing and inflation screw processing on end portions of highly stiff reinforcing bars, problems in which a texture of reinforcing bars changes and a texture strength of adjacent end portions being annealed declines due to heat occur when a reinforcing bar texture of the end portions is hot-processed, and ductility of the texture declines when the reinforcing bar texture is cold-cut-processed, and in accordance with a problem of cutting a fiber texture of reinforcing bars in accordance with the cutting in screw processing, a screw portion with a relatively declined texture strength with respect to the reinforcing bars is processed, thus causing poor joining.

In addition, when cold forging is performed, stiffness of a surface portion of a cross-sectional surface of a texture of a reinforcing bar is high while stiffness of a central portion thereof declines, thus causing an external stiff texture to be pushed into an inner portion when the cold-processing treatment is performed and causing a great concern of slight crystal breakage.

Also, when screw threads are rolled, wear of a rolling roller increases due to highly stiff reinforcing bars, thus causing loss of expenditure by shortening a life of a consumed tool.

Furthermore, with respect to joining reinforcing bars screw-processed in the same direction at both end portions, even in a method of joining the reinforcing bars at both of the end portions by forming screws in the same direction at sleeve-shaped couplers having screw threads formed at inner circumferential surfaces coupled to end portions of the reinforcing bars, there is an inconvenience of having to perform a construction work by rotating the reinforcing bars while the reinforcing bars at both of the end portions abut each other to be joined.
