Description

Reinforced Connection Device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing bar connecting apparatus, and more particularly, to a reinforcing bar connecting apparatus capable of connecting two reinforcing bars in a straight line.

BACKGROUND ART [0002] Generally, a reinforcing bar connecting device is a device for extending a length of a reinforcing bar by connecting two or more ends of two different reinforcing bars. Various types of reinforcing bar connecting devices capable of performing the above functions have been devised.

Hereinafter, a conventional reinforcing bar coupling device (Application No. 10-2004-0007779) will be described with reference to the accompanying drawings.

1 is an exploded view of a conventional reinforcing bar connection device.

As shown in FIG. 1, the conventional reinforcing bar coupling device has three engaging pieces 15 tightly coupled to the outer surface of a reinforcing bar, and a supporting portion 11 for fixing the position of each piece 15 A fixing part 20 for fixing the position of the engaging part 10 and a fastening part 21 for fastening the fastening part 21 to the fastening part 20, And a tightening nut 30 which is formed with a male thread 32 and which is engaged with the fixing part 20 after the piece 15 is pulled into the inside and the piece 15 is brought into close contact with the reinforcing bar.

The reinforcing bar coupled to the reinforcing linking device is inserted into the reinforcing bar insertion port 31 of the tightening nut 30 and passes through the engaging portion 10 and then reaches the support receiving plate 22 formed on the inner side of the fixing portion 20 Are inserted and joined.

The coupling portion 10 and the tightening nut 30 are coupled to both sides of the fixing portion 20 so that the two reinforcing bars can be coupled in a line.

The piece 15 is composed of an insertion end 16 inserted and fixedly coupled to the support 11 and a protruding end 17 fixed to the outside of the support 11 in engagement with the support 11 And on the inner side thereof, a release preventing protrusion 18 for preventing the detachment of the reinforcing bar by engaging the reinforcing protrusion formed on the surface of the reinforcing bar is formed.

The supporting body 11 is formed of an elastic material and has a circular band shape with an empty central portion and has a piece engaging hole 12 having a size and shape such that the insertion end 16 can be inserted in a fitting manner.

The fixing portion 20 contacts the end of the supporting body 11 when the engaging portion 10 is inserted into a part of the inner side surface so as to limit the insertion distance of the engaging portion 10 and to protrude toward the center axis The support plate 22 is formed.

In the conventional reinforcing bar coupling device having such a structure, one fixing part 20 and a pair of tightening nuts 30 are required as the essential components for fixing the engaging part 10 and fastening the piece 15 So that it is difficult to reduce the number of components.

Further, since the conventional reinforcing bar connecting device is structured such that the fastening nut 30 is detached by rotating the fastening nut 30 after the fastening portion 20 is fixed, the user can use a pair of fastening nuts 30 at the same time to the fixing part 20 or to separate the pair of tightening nuts 30 from the fixing part 20 at the same time.

Accordingly, when connecting and disassembling different reinforcing bars using conventional reinforcing bars, it is not only inconvenient to use, but also has a drawback in that it takes much time to connect and disassemble bars.

2 shows a process of manufacturing a piece to be applied to a conventional reinforcing bar.

The conventional piece 15 is manufactured by forming a pipe 1 having a predetermined length as shown in FIG. 2 (a) and forming a female screw 2 on the inner surface of the pipe 1 as shown in FIG. 2 (b) A step of machining the outer surface shape of the pipe 1 as shown in Fig. 2 (c), and a step of radially cutting the pipe 1 with reference to the central axis as shown in Fig. 2 (d).

At this time, in the step of forming the female thread 2 and the step of machining the outer surface shape of the pipe 1, if the rotation axis of the cutting tool for forming the female thread 2 does not perfectly coincide with the central axis of the pipe 1, The female thread 2 is not formed evenly on the entire inner surface of the cutting tool 1, and a lot of raw material loss occurs during various cutting operations, and there is a risk that the tool is damaged when an external force is applied due to a minute crack formed during cutting .

In addition, in the case of manufacturing the pieces by the conventional process of manufacturing a piece, the process of cutting the pipe 1 as shown in FIG. 2 (d) so that mutual interference does not occur when the pieces 15 are closely attached to the reinforcing bars The excess part 1a having a size larger than a predetermined size is cut between the pieces 15, and at this time, since the excess part 1a is a part to be discarded, there is a problem that raw material loss is largely generated.

In addition, the conventional process of manufacturing a piece is not only large in number of steps, but also requires a certain amount of time to be consumed in each process, and thus has a drawback in that it is difficult to improve the productivity.

Meanwhile, in order to strengthen KS quality standard of reinforcing bars, regulations for special high-strength seismic reinforcing bars and screw bars (KSD 3504, bars for reinforced concrete) are being revised.

The standard use of reinforcing bars is to expand the use of high-strength reinforcing bars, special vibration-proof reinforcing bars, and screw reinforcing bars to enhance the safety of buildings and to facilitate construction, reduce rebar consumption and construction costs, and reduce carbon footprint due to climate change .

Therefore, in order to improve the safety quality of ordinary reinforcing bars, the upper limits of phosphorus (P) and sulfur (S) are strengthened, the upper limit of yield strength is newly established, and the general reinforcement steel (SKSD 3504) The national standard for high-performance rebar (KSD 3688) has been incorporated into KSD 3504 to use special seismic reinforcing bars.

These ordinary reinforcing bars must be welded at the construction site or screwed into the ends of the reinforcing bars and connected by a coupler. Screw reinforcing bars should be able to be connected to the reinforcing bars by a coupler.

Accordingly, a coupler has to be used in order to connect reinforcing bars. The conventional coupler is composed of a plurality of parts, which increases the manufacturing cost and requires a long operation time since several parts are combined.
