SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the prior art, and it is an object of the present invention to provide a reinforced- The present invention also provides a reinforcing bar connecting member capable of fixedly supporting each reinforcing bar more firmly and capable of reducing the manufacturing cost due to the simple construction in manufacturing the reinforcing bar connecting member, will be.

In order to achieve the above object,

A method of manufacturing a reinforcing connector,
A first step of rotating the insert connected to the threading machine in a receiving space inside the body to form the threaded portion at a constant pitch; A second step of inserting the first jig into the body lower receiving space and positioning the first jig to the middle portion of the receiving space; A third step of pressing and inserting a plate member having a shape bent upward or downward in a direction from the center to the outer periphery into the upper accommodation space of the body; And a fourth step of inserting the second jig into the upper housing space of the body and positioning the plate member up to the middle of the housing space.

FIGS. 9 and 10 are diagrams illustrating an operation process according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

A reinforcing bar (10) having a receiving space (21) for accommodating a plurality of reinforcing bars therein,

The reinforcement connector 10 includes a body 20 having a threaded portion 22 formed on an inner circumferential surface of a receiving space 21 and a plate member 22 secured to the threaded portion 22 at a center of the accommodating space 21 of the body 20 30).

Hereinafter, the constituent elements and actions of the present invention will be described in detail as follows.

As shown in Fig. 3,

The reinforcing bar 10 of the present invention mainly comprises a body 20 and a plate member 30.

The body 20 includes a threaded portion 22 formed with a hollow receiving space 21 therein and a threaded portion continuous with the inner peripheral surface of the receiving space 21 and threaded portions 22, Is a hexahedron, but the shape of the body 20 is not limited to any one.

The plate member 30 is formed in the receiving space 21 of the body 20 in the form of a disk having a larger diameter than the inner diameter and has a shape bent upward or downward from the center to the outer periphery, And is fixed to the threaded portion of the central portion.

Meanwhile, in the manufacturing process of the reinforcing bar 10 of the present invention,

As shown in Figs. 4 to 8,

A first step of forming a threaded portion 22 on an inner peripheral surface of the body 20 where the receiving space 21 is formed;

In the first step, the inserts connected to the threading machine are rotated in the receiving space 21 inside the body 20 to form the threads and the threads at a constant pitch.
