본 발명은 봉 연결장치에 관한 것으로, 보다 상세하게는 2개 또는 그 이상의 철근 또는 파이프와 같은 봉들을 쉽고 확고하게 연결할 수 있는 봉 연결장치에 관한 것이다.The present invention relates to a rod connecting device, and more particularly, to a rod connecting device capable of easily and firmly connecting rods such as two or more reinforcing bars or pipes.

철근 또는 파이프와 같은 봉들을 연결하는 연결장치의 일례로 본 출원인의 등록실용신안 제20-0347218호의 「파이프용 조인트」를 들 수 있다.An example of the connecting device for connecting rods such as reinforcing bars or pipes is the "pipe joint" of the applicant's registered utility model No. 20-0347218.

도 5에 도시된 바와 같이, 종래의 파이프용 조인트는 한 쌍의 몸체(20)를 갖고 있다.As shown in FIG. 5, a conventional pipe joint has a pair of bodies 20.

한 쌍의 몸체(20)는 파이프(10)가 각각 입구(26)쪽에서 끼워지게 배치되고, 입구(26)에는 내부로 먼지나 오수 등이 침투하는 것을 막기 위한 마개(28)가 설치되어 있다.The pair of bodies 20 are arranged so that the pipes 10 are fitted at the inlet 26, respectively, and a stopper 28 is provided at the inlet 26 to prevent dust or sewage from penetrating into the inside.

몸체(20)는 내벽에 입구(26)쪽에 안쪽으로 내경이 커지도록 테이퍼(23)가 형성되어 있고, 보다 안쪽에는 요홈부(22)가 형성되어 있다. 테이퍼(23)와 요홈부(22)가 연결되는 부위는 걸림턱(21)이 형성되어 있다.The body 20 is formed on the inner wall with a taper 23 so as to have an inner diameter larger toward the inlet 26, and a recess 22 is formed on the inner wall. A locking jaw 21 is formed at a portion where the taper 23 and the recess 22 are connected to each other.

요홈부(22)에는 조인트의 기밀을 유지하기 위한 패킹(27)이 설치되어 있고, 걸림턱(21)에는 스냅링(29)이 설치되어 있다.The recess 22 is provided with a packing 27 for maintaining the airtightness of the joint, and a snap ring 29 is provided at the locking jaw 21.

파이프(10)를 고정하기 위한 스토퍼(25)는 몸체(20) 안에 테이퍼(23)를 따라 운동하게 설치되어 있고, 스냅링(29)과 스토퍼(25) 사이에는 스프링(24)이 설치되어 스토퍼(25)에 길이방향으로 탄성력을 부여하고 있다. 또한 스프링(24)의 마지막 권(24a)은 스토퍼(25)에 형성된 홈에 끼워져 있다.The stopper 25 for fixing the pipe 10 is installed to move along the taper 23 in the body 20, and a spring 24 is installed between the snap ring 29 and the stopper 25 so that the stopper ( 25, an elastic force is applied in the longitudinal direction. In addition, the last winding 24a of the spring 24 is fitted in the groove formed in the stopper 25.

상술한 구성을 갖는 종래의 파이프용 조인트는 스토퍼(25)가 1단으로 이루어져 있어 파이프(10)간의 충분한 결합력을 유지하기 위한 스토퍼(25)와 파이프(10)간의 접촉면적과 스토퍼(25)와 몸체(20)간의 접촉면적을 크게 하기 위해서는 스토퍼(25)를 포함한 조인트 전체가 커져야 하는 문제가 있었다. 따라서 조인트를 소형화하는 데 한계가 있었고 이는 제조가의 상승과 함께 작업의 효율성을 크게 저해하는 요인이 되었다.In the conventional pipe joint having the above-described configuration, the stopper 25 has a single stage, and the contact area between the stopper 25 and the pipe 10 and the stopper 25 and the stopper 25 for maintaining a sufficient coupling force between the pipes 10 and In order to increase the contact area between the bodies 20, there was a problem that the entire joint including the stopper 25 had to be large. Therefore, there was a limit to miniaturization of the joint, which was a factor that greatly hindered the work efficiency with the increase of the manufacturing price.

특히 철근연결을 위한 커플러나 와이어로프 연결장치는 연결 대상물 원래의 인장강도와 항복강도를 확보하면서도 체적이 작고 안정된 결합력을 구현하는 것이 중요하다. In particular, it is important for the coupler or the wire rope connecting device for reinforcing bar connections to achieve a small and stable coupling force while securing the original tensile strength and yield strength.

To provide a rod connection.

본 발명의 봉 연결장치는 한 쌍의 몸체의 전체 길이가 스토퍼가 2단일 때는 외경의 1.8~2.0배, 스토퍼가 3단일 때는 외경의 2.4~2.6배인 것을 특징으로 하고, 또한 몸체의 외경과 봉의 외경의 비가 9:5인 것을 특징으로 한다.The rod connecting device of the present invention is characterized in that the total length of the pair of the body is 1.8 to 2.0 times the outer diameter when the stopper is in two stages, and 2.4 to 2.6 times the outer diameter when the stopper is in three stages, and also the outer diameter of the body and the outer diameter of the rod. Is characterized by a ratio of 9: 5.

또한 본 발명의 봉 연결장치는 한 쌍의 몸체가 다수의 스토퍼들이 수용되는 길이방향으로 2단 또는 다단으로 형성된 경사면을 갖는 것을 특징으로 하고, 몸체의 최소두께는 상기 몸체반경과 봉의 반경의 차이의 40% 이상인 것을 특징으로 하고, 경사면은 경사각이 10°~20°인 것과, 구체적으로 경사각이 12°~15°인 것을 특징으로 한다.In addition, the rod connecting device of the present invention is characterized in that the pair of the body has a slope formed in two or multi-stage in the longitudinal direction in which a plurality of stoppers are accommodated, the minimum thickness of the body of the difference between the radius of the body and the radius of the rod It is characterized by more than 40%, the inclined surface is characterized in that the inclination angle is 10 ° ~ 20 °, specifically the inclination angle is 12 ° ~ 15 °.

또한 본 발명의 봉 연결장치는 다수의 스토퍼들이 끝이 짤린 원추형상을 하고 원주방향으로 3개 내지 6개로 분할되게 형성되는 것을 특징으로 하고, 다수의 스토퍼들은 안쪽면에 직삼각형 모양의 다수의 톱니모양의 돌기들이 형성되는 것을 다른 특징으로 한다.In addition, the rod connecting device of the present invention is characterized in that the plurality of stoppers are formed in a conical shape cut off the end is divided into three to six in the circumferential direction, the plurality of stoppers are in the form of a plurality of sawtooth in the form of a right triangle on the inner surface Is characterized in that the protrusions are formed.

In addition, since the contact area between the stopper and the body is increased, the tensile strength and yield strength are increased while the outer diameter of the apparatus is small.

이렇게 몸체와 스토퍼, 봉과 스토퍼 간의 접촉면적을 크게 하면서도 장치 전체의 크기를 줄일 수 있어 철근연결이나 와이어로프 연결장치에 적합한 설계를 할 수 있으며 제조가를 낮추고 작업의 효율성을 높일 수 있다. In this way, the contact area between the body and the stopper, the rod and the stopper can be increased while the overall size of the device can be reduced, so that a design suitable for the rebar connection or the wire rope connection device can be designed, and the manufacturing cost can be reduced and the work efficiency can be increased.

이하 첨부한 도면을 참조로 본 발명의 바람직한 실시예에 따른 봉 연결장치에 대하여 상세하게 설명한다.Hereinafter, a rod connecting apparatus according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

도 1 및 도 2, 도 3을 참조로 본 발명의 바람직한 실시예에 따른 봉 연결장치에 대하여 설명한다. 도 1은 본 실시예에 따른 봉 연결장치의 개략적인 분해 사시도이고, 도 2는 2단의 스토퍼가 장착된 도 1의 봉 연결장치의 개략적인 단면도이며 도 3은 스토퍼가 3단으로 장착된 봉 연결장치의 개락적인 단면도이다.1 and 2, 3 will be described with respect to the rod connecting device according to a preferred embodiment of the present invention. 1 is a schematic exploded perspective view of a rod connecting device according to the present embodiment, Figure 2 is a schematic cross-sectional view of the rod connecting device of Figure 1 is equipped with a two-stage stopper and Figure 3 is a rod equipped with a stopper in three stages It is a general cross section of a connection device.

도 1 및 도 2, 도 3에 도시한 바와 같이, 본 실시예에 따른 봉 연결장치(100)는 한 쌍의 몸체(110), 다수의 스토퍼(120), 스프링(130) 및 탄성링(140)을 포함한다.1, 2, and 3, the rod connecting device 100 according to the present embodiment is a pair of body 110, a plurality of stoppers 120, spring 130 and elastic ring 140 ).

한 쌍의 몸체(110)는 봉(1)과 같은 물체를 수용하기 위한 것으로, 원통형상으로 서로 마주하는 형태를 갖는다. 몸체(110)에는 내주를 따라 2단의 경사면(111)이 길이방향으로 나란히 형성되고, 그 중간에 봉(1)이 걸리게 되는 걸림턱(112)이 형성된다. 한 쌍의 몸체(110)는 제조시 일체로 만들어지거나, 분리되게 만들어진 후 용접 또는 볼트/너트와 같은 분리 가능한 체결수단에 의해 일체로 만들어질 수 있다.The pair of bodies 110 are for accommodating an object such as a rod 1, and have a cylindrical shape facing each other. The body 110 has two inclined surfaces 111 along the inner circumference, formed side by side in the longitudinal direction, and a locking jaw 112 through which the rod 1 is caught in the middle thereof. The pair of bodies 110 may be made integrally at the time of manufacture, or may be made integrally by means of detachable fastening means such as welding or bolts / nuts after being made separate.

장착되는 스토퍼(120)의 단수가 많을수록 쐐기의 봉에 대한 물림의 건전 성(integrity)이 향상된다. 또한 스토퍼(120)의 경사각(α)을 바꾸지 않고도 스토퍼(120)가 몸체(110)에 미치는 힘을 분산시킬 수 있으므로 최소외경을 갖는 몸체를 설계할 수 있다. 예를 들어 동일 경사각의 1단의 스토퍼를 장착하여 다단의 스토퍼와 같은 효과를 내려면 경사면의 밑면 길이(l)를 크게 해야 하므로 몸체(110)의 두께가 다단 스토퍼 장착 때보다 커져야 하며, 상기 경사면 밑면의 길이(l)는 같으나 경사각(α)이 다른 스토퍼를 사용한다면 1단 스토퍼(120)일 때는 다단 스토퍼일 때보다 경사각(α)이 줄어드는 만큼 빗면(inclined plane)의 원리에 의해 스토퍼(120)가 몸체(110)에 미치는 힘이 커지므로 이에 대응하려면 몸체(110)의 두께는 증가해야 한다. 즉, 스토퍼가 다단으로 장착될 때 봉을 안정적으로 연결하는 최소체적의 연결장치를 제작할 수 있는 것이다.As the number of steps of the stopper 120 to be mounted increases, the integrity of the bite on the wedge rod is improved. In addition, since the force applied to the body 110 by the stopper 120 can be distributed without changing the inclination angle α of the stopper 120, a body having a minimum outer diameter can be designed. For example, in order to achieve the same effect as a multi-stage stopper by mounting a stopper of the same inclination angle, the thickness of the bottom surface of the inclined surface must be increased (l), so that the thickness of the body 110 must be larger than that of the multi-stage stopper. If a bottom stopper 120 having the same length l but different inclination angle α is used, the stopper 120 is reduced by the inclination plane as the inclination angle α is reduced when the first stopper 120 is smaller than the multistage stopper. ) Increases the force on the body 110, the thickness of the body 110 should be increased to correspond to this. In other words, when the stopper is mounted in multiple stages, it is possible to manufacture the minimum volume connection device for stably connecting the rods.

본 발명의 장치를 항복강도와 인장강도는 연결대상물인 봉에 못지 않으면서 최소체적을 갖도록 스토퍼(120)의 크기를 감안하여 설계해 본 결과, 바람직한 몸체(110)외경(D)과 봉(1)의 외경(d)의 비는 9:5인 것으로 도출되었다. Yield strength and tensile strength of the device of the present invention is designed in consideration of the size of the stopper 120 to have a minimum volume as well as the rod that is the connection object, the preferred body 110, the outer diameter (D) and rod (1) ), The ratio of the outer diameter d is derived to be 9: 5.

또한 몸체(110)의 최소두께가 몸체 반경과 봉 반경 차이｛(D-d)/2｝의 40% 이상이면 몸체의 최소 단면적은 봉(1)의 단면적을 초과하는 최소의 외경을 갖는 몸체(110)를 설계할 수 있다. 이를 식으로 정리하면 0.4｛(D-d)/2｝×(D-0.8)

This can be summarized as 0.4 ｛(Dd) / 2｝ × (D-0.8)

한 쌍의 몸체(110)의 전체 길이(L)는 스토퍼가 2단으로 장착될 때 외경(D)의 약 1.8~2.0배가 바람직하며 스토퍼가 3단으로 장착될 때 외경의 2.4~2.6배가 바람직하다. The total length L of the pair of bodies 110 is preferably about 1.8 to 2.0 times the outer diameter D when the stopper is mounted in two stages, and preferably 2.4 to 2.6 times the outer diameter when the stopper is mounted in three stages. .
