본 발명은 나사철근 연결장치에 관한 것으로, 더욱 상세하게는 기계적인 방식으로 나사철근과 나사철근을 연결하는 나사철근 연결장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw reinforcing bar connecting device, and more particularly, to a screw reinforcing bar connecting device for connecting a screw bar to a screw bar in a mechanical manner.

콘크리트 구조물에서 골조로 사용되는 철근은 운반이나 작업 편의를 위해 한정된 길이로 생산되기 때문에 대부분 연결하여 사용하게 되며, 철근을 연결하기 위한 방식은 기계적인 방식, 겹침 이음 방식 등 여러 가지가 있다. Reinforcing bars used in concrete structures are produced in limited lengths for transportation or work convenience, and most of them are used in connection. There are many methods for connecting reinforcing bars such as mechanical method and lap joint method.

본 발명과 관련된 선행기술은 국내공특허공보 제10-2006-0110610호(2006.10.25)_"철근 연결부 구조 및 철근 연결방법"이 있다. Prior art relating to the present invention is disclosed in Korean Patent Publication No. 10-2006-0110610 (October 25, 2006) _ "Reinforcing connection structure and reinforcing connection method ".

본 발명의 목적은 나사철근과 나사철근의 연결 작업이 용이하고, 연결 후 체결력이 증대되어 반복되는 하중에도 유격 발생이 방지되는 나사철근 연결장치를 제공하는 것이다.An object of the present invention is to provide a screw reinforcing bar connection device in which a connecting operation between a screw reinforcement and a screw reinforcement is easy and an engaging force is increased after connection to prevent a clearance from occurring even under repeated loads.

상기한 바와 같은 목적을 달성하기 위한 본 발명의 특징에 따르면, 본 발명은 나사철근과 나사철근을 상호 연결하도록, 길이방향으로 연결공이 형성되며 상기 연결공에 상기 나사철근의 나사에 대응되는 나사산이 형성되며 양단에 노치홈이 형성된 커플러부재와, 상기 커플러부재의 양단에 결합되고 상기 커플러부재의 양단을 밀어주면서 조이도록 선단에서 내측으로 갈수록 내경이 작아지게 테이퍼 가공된 결합공이 형성되는 너트부재를 포함한다.According to an aspect of the present invention for achieving the above object, the present invention is characterized in that a connecting hole is formed in the longitudinal direction so as to interconnect the screw reinforcement and the screw reinforcement, and a screw thread corresponding to the screw of the screw reinforcement And a nut member having a notch groove formed at both ends thereof, and a nut member coupled to both ends of the coupler member and having a tapered engagement hole formed inside the coupler member so as to push the opposite ends of the coupler member toward the inside thereof do.

상기 커플러부재는 다각형의 외면을 갖고 길이방향 중심 부분에 상기 내경과 수직으로 연통되는 핀공이 형성된 몸체부와, 상기 몸체부의 양단에서 단차져 형성되고 원형의 외면을 가지며 상기 노치홈이 형성된 결합부를 구비한다.The coupler member includes a body portion having an outer surface of a polygonal shape and having a pin hole formed at a longitudinal center portion thereof and communicating with the inner diameter in a direction perpendicular to the inner diameter of the body portion, do.

상기 노치홈은 상기 커플러부재의 양단에서 외측으로 개구되고 단부가 라운드진 U자형 노치홈이다.The notch groove is a U-shaped notch groove which is opened at both ends of the coupler member outwardly and has an end rounded.

상기 커플러부재의 양단은 선단에서 내측으로 갈수록 외경이 커지게 테이퍼 가공된다.Both ends of the coupler member are tapered so that their outer diameters become larger toward the inner side from the tip end.

상기 너트부재는 상기 결합공과 연통되게 상기 나사철근의 나사에 대응되는 나사공이 더 형성된다.The nut member is further provided with a screw hole corresponding to the screw of the screw thread so as to communicate with the engagement hole.

상기 너트부재는 외면이 상기 커플러부재의 외면과 동일한 형상의 다각형이다.The nut member has a polygonal shape whose outer surface has the same shape as the outer surface of the coupler member.

본 발명은 나사철근과 나사철근을 연결하는 커플러부재와 너트부재가 테이퍼면과 테이퍼면의 결합에 의해 서로 밀어주면서 조여지는 구조로 형성되므로 나사철근의 체결력이 증가된다.In the present invention, the fastening force of the screw reinforcement is increased because the coupler member connecting the screw reinforcement and the screw reinforcement and the nut member are formed by tightening while being pushed together by the engagement of the tapered surface and the tapered surface.

또한, 본 발명은 커플러부재의 결합부에 형성된 노치홈에 의해 너트부재의 결합공이 내측으로 갈수록 내경이 감소하게 테이퍼진 형상임에도 불구하고 커플러부재와 너트부재의 결합이 용이하고 결합된 후의 체결력은 더 증가된다. Further, although the coupling hole of the nut member is tapered to have a reduced inner diameter as the coupling hole of the nut member is inwardly tapered by the notch groove formed in the coupling portion of the coupler member, the coupler member and the nut member are easily coupled, .

따라서, 본 발명은 나사철근의 체결력을 증가시키면서도 공사 현장에서 간편하게 나사철근을 연결할 수 있으며, 체결력 증가에 의해 반복되는 하중에도 나사철근과 커플러부재, 커플러부재와 너트부재 및 나사철근과 나사철근의 유격 발생이 방지되는 효과가 있다.Accordingly, the present invention can easily connect the screw reinforcement at the construction site while increasing the fastening force of the screw reinforcement, and the screw reinforcement and the coupler member, the nut member, the screw reinforcement and the screw reinforcement There is an effect that occurrence is prevented.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 나사철근 연결장치는, 나사철근과 나사철근을 길이방향으로 상호 연결하는 나사철근 연결장치이다.The screw reinforcing bar connection device of the present invention is a screw reinforcing bar connection device for interconnecting screw reinforcement bars and screw reinforcing bars in the longitudinal direction.

설명의 편의를 위해 도 3 및 도 4를 참조하여 나사철근에 대해 간단하게 설명한다. For ease of explanation, the screw reinforcement will be briefly described with reference to Figs. 3 and 4. Fig.

도 3 및 도 4에 도시된 바와 같이, 나사철근(1,3)은 가공을 거치치 않고 철근 생산부터 전 마디가 전조나사 형태로 만들어진 철근이다. 나사이음철근은 건설현장에서 길이가 안 맞을 경우 재가공해야하는 불편함이 있는 반면, 나사철근은 절단 후 바로 사용 가능하다. As shown in Figs. 3 and 4, the screw reinforcement bars 1 and 3 are reinforcing bars made from the production of reinforcing bars without machining, and the front joints are formed in the form of rolling screws. Threaded rebars are inconvenient to rework when the length of the rebar is not correct at the construction site, whereas screw rebars are available immediately after cutting.

또한, 나사철근(1,3)은 나사이음철근이 가공과정을 거치면서 발생되는 운반비, 가공비 등을 절감할 수 있다. In addition, the screw reinforcement (1, 3) can reduce the transportation cost and the processing cost incurred when the threaded reinforcement is subjected to the machining process.

도 1 및 도 2에 도시된 바와 같이, 나사철근 연결장치는 커플러부재(10)와, 커플러부재(10)의 양단에 결합되어 커플러부재(10)와 나사철근(1,3)의 유동을 방지하는 너트부재(20)를 포함한다. As shown in Figs. 1 and 2, the screw-and-bar coupling device comprises a coupler member 10 and a coupling member 10 which is coupled to both ends of the coupler member 10 to prevent the flow of the coupler member 10 and the screw rods 1, And a nut member (20).

커플러부재(10)는 일정한 길이를 갖고 외면은 다각형 형상이다. 커플러부재(10)는 길이방향으로 관통되게 연결공(11)이 형성되며, 연결공(11)에 나사철근(1,3)의 나사(1a,3a)에 대응되는 나사산이 형성된다. The coupler member 10 has a predetermined length and its outer surface is polygonal. The coupler member 10 is formed with a connecting hole 11 so as to penetrate in the longitudinal direction and a thread corresponding to the screws 1a and 3a of the screw rods 1 and 3 is formed in the connecting hole 11. [

본 실시예의 커플러부재(10)는 외면이 육각형 형상이다. 육각형 형상은 파지가 용이하고 원형에 비해 조이는 힘이 적게 들어 공사 현장에서 간편하게 나사철근(1)과 나사철근(3)을 연결하는데 유용하다.The outer surface of the coupler member 10 of this embodiment is hexagonal. The hexagonal shape is easy to grasp and has less tightening force than the round shape, which is useful for connecting the screw reinforcement (1) and the screw reinforcement (3) easily at the construction site.

커플러부재(10)는 몸체부(13)와, 몸체부(13)의 양단에서 단차져 형성된 결합부(17)로 구성된다. 몸체부(13)의 외면이 육각형 형상이며 결합부(17)의 외면은 원형이다.The coupler member 10 is constituted by a body portion 13 and a coupling portion 17 formed integrally at both ends of the body portion 13. The outer surface of the body portion 13 is hexagonal and the outer surface of the coupling portion 17 is circular.

몸체부(13)의 길이방향 중심 부분에는 핀공(15)이 형성된다. A pin hole 15 is formed in the longitudinal center portion of the body portion 13.

핀공(15)은 길이방향 중심 부분에 상하 2개가 형성되며 몸체부(13)의 내경과 수직으로 연통된다. 핀공(15)에는 나사철근(1)과 나사철근(3)의 연결시 각 나사철근(1,3)의 단부가 삽입되는 기준점을 정하기 위한 기준핀(미도시)이 삽입된다.Two upper and lower holes 15 are formed in the center portion in the longitudinal direction and communicate with the inner diameter of the body portion 13 in a vertical direction. A reference pin (not shown) is inserted into the pin hole 15 to define a reference point at which the ends of the respective screw reinforcement bars 1 and 3 are inserted when the screw reinforcement 1 and the screw reinforcement 3 are connected.

결합부(17)에 너트부재(20)가 결합된다. And the nut member 20 is engaged with the engaging portion 17.

결합부(17)는 원형의 외면을 가지며 외측으로 개방된 노치홈(19)이 형성된다. 원형의 외면을 갖는 결합부(17)는 너트부재(20)와의 조임 결합을 용이하게 한다. 그리고, 노치홈(19)은 너트부재(20)와의 결합시 결합부(17)가 일정부분 탄성 변형되게 하여 조임력을 증대시킨다.The engaging portion 17 has a notched groove 19 having a circular outer surface and being open to the outside. The engaging portion 17 having a circular outer surface facilitates fastening engagement with the nut member 20. The notch groove 19 elastically deforms the engaging portion 17 when the nut member 20 is engaged with the nut member 20, thereby increasing the tightening force.

노치홈(19)은 단부가 라운드진 U자형 노치홈(19)인 것이 바람직하다. V자형 노치홈은 인장 테스트나 현장에서 직접 하중을 받을 경우 크랙 발생이 우려되므로 U자형 노치홈인 것이 바람직하다.The notch groove 19 is preferably a rounded U-shaped notch groove 19 at the end. It is preferable that the V-shaped notch groove is a U-shaped notch groove since there is a risk of cracking when subjected to a tensile test or a direct load at the site.

U자형 노치홈(19)은 결합부(17)에 너트부재(20)의 결합시 결합부(17)의 외경을 탄성 변형시켜 결합을 용이하게 한다. The U-shaped notch groove 19 elastically deforms the outer diameter of the engaging portion 17 when the nut member 20 is engaged with the engaging portion 17, thereby facilitating the engagement.

도 2에 도시된 바와 같이, 결합부(17)의 외경은 선단에서 내측으로 갈수록 외경이 커지게 테이퍼 가공된다. 테이퍼 가공된 결합부(17)의 외경을 테이퍼면(17a)이라 칭한다. 결합부(17)의 테이퍼면(17a)은 아래에서 설명될 너트부재(20)의 테이퍼면(21a)과 결합시 밀어주면서 서로 조이는 역할을 한다.As shown in Fig. 2, the outer diameter of the engaging portion 17 is tapered so that the outer diameter becomes larger toward the inner side from the tip end. The outer diameter of the tapered engaging portion 17 is referred to as a tapered surface 17a. The tapered surface 17a of the engaging portion 17 pushes the tapered surface 21a of the nut member 20, which will be described later, and serves to tighten them together.

너트부재(20)는 커플러부재(10)의 양단에 형성된 결합부(17)에 결합된다. The nut member 20 is coupled to the coupling portion 17 formed at both ends of the coupler member 10.

너트부재(20)는 결합공(21) 및 나사공(23)이 연통되게 형성된다. 너트부재(20)는 너트부재(20)의 결합공(21)에 결합부(17)가 삽입되는 방식으로 결합부(17)에 결합된다. The nut member 20 is formed so that the engagement hole 21 and the screw hole 23 are communicated with each other. The nut member 20 is engaged with the engaging portion 17 in such a manner that the engaging portion 17 is inserted into the engaging hole 21 of the nut member 20. [

너트부재(20)의 결합공(21)은 커플러부재(10)의 결합부(17)를 밀어주면서 조이도록 선단에서 내측으로 갈수록 내경이 작아지게 테이프 가공된다. 테이프 가공된 결합공의 내주면도 테이퍼면(21a)으로 칭한다. The coupling hole 21 of the nut member 20 is tape-processed such that the inner diameter becomes smaller toward the inner side from the front end so as to push the coupling portion 17 of the coupler member 10 while pushing it. The inner peripheral surface of the tape-processed engagement hole is also referred to as a tapered surface 21a.

결합공(21)의 테이퍼면(21a)은 커플러부재(10)의 결합부(17)의 테이퍼면(17a)과의 결합을 견고하게 한다. The tapered surface 21a of the coupling hole 21 makes the coupling with the tapered surface 17a of the coupling portion 17 of the coupler member 10 firm.

본 실시예에서 결합공(21)의 내주면이 테이프진 각도는 6°로 하였다. 그러나 반드시 이에 한정되는 것은 아니고 설계 조건에 따라 테이프진 각도가 ±5°범위에서 변경 가능하다.In this embodiment, the inner peripheral surface of the engaging hole 21 has a taper angle of 6 degrees. However, the present invention is not limited to this, and the taper angle of the tape can be changed within the range of ± 5 ° according to the design conditions.

너트부재(20)의 결합공(21)의 선단은 커플러부재(10)의 결합부(17)의 선단 외경에 대응되어 결합부(17)에 너트부재(20)의 결합이 용이하도록 한다.The tip end of the coupling hole 21 of the nut member 20 corresponds to the outer diameter of the tip end of the coupling portion 17 of the coupler member 10 so that the coupling of the nut member 20 to the coupling portion 17 is facilitated.

너트부재(20)의 나사공(23)에 나사철근(1,3)의 나사(1a,3a)에 대응되는 나사산이 형성된다. 나사공(23)의 나사산은 커플러부재(10)의 연결공(11)에 형성된 나사산과 연속하는 나사산을 형성한다. Threads corresponding to the screws 1a and 3a of the screw rods 1 and 3 are formed in the screw holes 23 of the nut member 20. The thread of the screw hole 23 forms a continuous thread with the thread formed in the connecting hole 11 of the coupler member 10. [

너트부재(20)에도 결합력 증대를 위한 U자형의 노치홈(25)이 형성될 수 있다.The nut member 20 may also have a U-shaped notch groove 25 for increasing the bonding force.

너트부재(20)는 조임력 증대를 위한 회전시 작업이 용이하도록 외면이 다각형인 것이 바람직하며, 더욱 바람직하게는 외면이 커플러부재(10)와 동일하게 육각형인 것이 바람직하다. 너트부재(20)의 외면을 커플러부재(10)와 동일한 형상으로 하는 것은 나사철근(1,3)을 연결한 철근 연결장치의 외관을 미려하게 한다.The nut member 20 preferably has a polygonal outer surface to facilitate the operation during rotation for increasing the clamping force. More preferably, the outer surface of the nut member 20 is hexagonal like the coupler member 10. The outer surface of the nut member 20 having the same shape as that of the coupler member 10 makes the appearance of the reinforcing bar connecting device connected with the threaded reinforcing bars 1 and 3 smooth.

커플러부재(10)와 너트부재(20)는 체결력 증대를 위해 금속재질로 이루어진다.The coupler member 10 and the nut member 20 are made of metal to increase the fastening force.

커플러부재(10)와 너트부재(20)를 이용한 나사철근(1)과 나사철근(3)의 연결은 결합부(17)의 테이퍼면(17a)과 결합공(21)의 테이퍼면(21a)이 서로 밀어주면서 조여지는 결합이므로 체결력이 증대되고, 결합되는 과정에서 결합부(17)에 형성된 노치홈(19)에 의해 결합부(17)가 일정부분 탄성 변형되어 결합도 용이하다. The connection between the threaded reinforcing bar 1 and the threaded reinforcing bar 3 using the coupler member 10 and the nut member 20 is performed by the tapered surface 17a of the engaging portion 17 and the tapered surface 21a of the engaging hole 21, The fastening force is increased and the engaging portion 17 is elastically deformed by the notch groove 19 formed in the engaging portion 17 during the process of the engaging.

상술한 커플러부재(10)와 너트부재(20)의 결합은 인장시험이나 현장에서 직접 하중을 받을 때 나사철근(1,3)의 연신에 의해 체결력이 저하되지 않고, 너트부재(20)와 커플러부재(10)의 유격 발생도 방지된다.
The coupling between the coupler member 10 and the nut member 20 described above can be achieved by a combination of the nut member 20 and the coupler 20 without the deterioration of the fastening force due to the elongation of the threaded bars 1, Occurrence of clearance of the member 10 is also prevented.

이하 본 발명의 작용을 설명한다. The operation of the present invention will be described below.

나사철근 연결장치를 이용하여 나사철근과 나사철근을 연결하는 과정을 설명하기로 한다. The procedure of connecting the screw reinforcement to the screw reinforcement using the screw reinforcement connecting device will be described.

우선, 도 3에 도시된 바와 같이, 연결할 두 개의 나사철근을 준비하고, 각 나사철근에 너트부재를 결합한다. First, as shown in Fig. 3, two screw reinforcements to be connected are prepared, and the nut member is connected to each screw reinforcement.

너트부재(20)는 나사공(23)을 나사철근(1)의 길이방향 일단부와 대응되게 배치하고, 너트부재(20)의 나사공(23) 및 결합공(21)이 나사철근(1)의 일단부를 순차적으로 통과하게 하여 나사철근(1)의 일단부가 커플러부재(10)를 향해 돌출되게 한다.The nut member 20 has the screw hole 23 corresponding to one longitudinal end portion of the screw bar 1 and the screw hole 23 and the engaging hole 21 of the nut member 20 are screwed into the screw reinforcement 1 So that one end of the threaded reinforcing bar 1 is projected toward the coupler member 10.

이때, 너트부재(20)는 나사공(23)의 나사산이 나사철근(1)의 나사(1a)에 나사결합되는 방식으로 결합된다. 그리고, 너트부재(20)는 나사공(23)에 비해 결합공(21)의 내경이 더 크므로 결합과정에서 결합공(21)과 나사철근(1)의 외경과의 간섭은 발생되지 않는다.At this time, the nut member 20 is engaged in such a manner that the thread of the screw hole 23 is threadedly engaged with the screw 1a of the threaded reinforcing bar 1. Since the inner diameter of the coupling hole 21 is larger than that of the screw hole 23 in the nut member 20, interference between the coupling hole 21 and the outer diameter of the threaded reinforcing bar 1 does not occur during the coupling process.

나사철근(1)에 너트부재(20)의 결합이 완료되면 다른 나사철근(3)에도 상술한 방법과 동일한 방법으로 너트부재(20)를 결합한다. When the coupling of the nut member 20 to the screw reinforcement 1 is completed, the nut member 20 is coupled to the other screw reinforcement 3 in the same manner as described above.

다음으로, 각각 너트부재(20)가 결합된 나사철근(1)과 나사철근(3)을 커플러부재(10)로 연결한다. Next, the screw reinforcement 1 and the screw reinforcement 3, to which the nut member 20 is engaged, are connected to each other by the coupler member 10.

이를 위해, 커플러부재(10)의 핀공(15)에 기준핀을 삽입한다. 그리고, 커플러부재(10)의 일단 연결공(11)에 나사철근(1)을 나사 결합시킨다. 나사철근(1)의 결합은 나사철근(1)에 대해 커플러부재(10)를 상대 회전시켜 결합할 수 있다. To this end, the reference pin is inserted into the pin hole 15 of the coupler member 10. Then, the threaded reinforcing bar 1 is screwed to the connecting hole 11 at one end of the coupler member 10. The coupling of the screw reinforcement 1 can be engaged by relative rotation of the coupler member 10 with respect to the screw bar 1. [

커플러부재(10)를 회전하는 과정에서 커플러부재(10)가 나사철근(1)에 대해 더 이상 회전하지 않으면 나사철근(1)의 단부가 기준핀 위치에 위치한 것으로 보고 커플러부재(10)의 회전을 중지한다.If the coupler member 10 is no longer rotated with respect to the screw bar 1 in the process of rotating the coupler member 10, the end of the screw bar 1 is positioned at the reference pin position and the rotation of the coupler member 10 Lt; / RTI >

다음으로, 커플러부재(10)의 타단 연결공(11)에도 나사철근(3)을 결합한다. 이때, 나사철근(3)을 커플러부재(10)에 대해 상대 회전시켜 결합할 수 있다. Next, the threaded reinforcing bar 3 is engaged with the other end connecting hole 11 of the coupler member 10 as well. At this time, the screw reinforcement 3 can be engaged with the coupler member 10 by rotating relative thereto.

나사철근(3)이 회전하는 과정에서 나사철근(3)이 더 이상 회전하지 않으면 나사철근(3)의 단부가 기준핀 위치에 위치한 것으로 보고 나사철근(3)의 회전을 중지한다. If the screw reinforcement 3 is no longer rotated during the rotation of the screw reinforcement 3, the end of the screw reinforcement 3 is positioned at the reference pin position, and the rotation of the screw reinforcement 3 is stopped.

다음으로 커플러부재(10)의 핀공(15)에 삽입된 기준핀을 제거한다. 커플러부재(10)에 나사결합된 각 나사철근(1,3)의 단부는 기준핀에 의해 커플러부재(10)의 중간 부분에 위치된다. Next, the reference pin inserted into the pin hole 15 of the coupler member 10 is removed. The end portions of the respective screw rods 1 and 3 screwed to the coupler member 10 are positioned at the middle portion of the coupler member 10 by the reference pins.

각 나사철근(1,3)의 단부가 커플러부재(10)의 중간 부분에 위치되게 커플러부재(10)에 나사철근(1,3)이 결합되면, 각 나사철근(1,3)에 결합된 너트부재(20)를 회전시켜 커플러부재(10)의 결합부(17)에 결합시킨다. When the screw reinforcement members 1 and 3 are coupled to the coupler member 10 such that the end portions of the respective screw reinforcement members 1 and 3 are positioned at the intermediate portion of the coupler member 10, The nut member 20 is rotated and engaged with the coupling portion 17 of the coupler member 10. [

이 과정에서 결합부(17)의 테이프면(17a)을 너트부재(20) 결합공(21)의 테이프면(21a)이 밀어주면서 조여지고, 결합부(17)의 노치홈(19)에 의해 결합부(17)의 외경이 일정부분 탄성 변형되므로 결합부(17)에 너트부재(20)의 결합이 용이하다. The tape surface 17a of the engaging portion 17 is tightened while the tape surface 21a of the engaging hole 21 of the nut member 20 is pushed by the notch groove 19 of the engaging portion 17 The outer diameter of the engaging portion 17 is elastically deformed to a certain extent, so that the nut member 20 can be easily engaged with the engaging portion 17.

또한, 커플러부재(10)의 결합부(17)에 너트부재(20)가 결합된 후에는 결합부(17)가 복원되는 힘에 의해 너트부재(20)의 결합공(21)에 밀착되므로 커플러부재(10)와 너트부재(20)의 체결력이 높아진다. After the nut member 20 is coupled to the coupling portion 17 of the coupler member 10, the coupling portion 17 is brought into close contact with the coupling hole 21 of the nut member 20 by the restoring force, The fastening force between the member 10 and the nut member 20 is increased.

따라서, 높은 체결력으로 결합된 커플러부재(10)와 너트부재(20)에 의해 나사철근(1,3)은 인장시험이나 현장에서 직접 하중을 받을 때 나사철근(1,3) 연신에 의한 체결력 저하가 방지되고, 나사철근(1,3)과 커플러부재(10), 커플러부재(10)와 너트부재(20) 및 나사철근(1,3) 상호 간의 유격 발생도 방지된다.
Therefore, the screw rods (1, 3) can be prevented from being deteriorated in the fastening force due to the threaded reinforcing bar (1, 3) stretch when subjected to a tensile test or a direct site load by the coupler member (10) and the nut member And the gap between the screw reinforcement members 1 and 3 and the coupler member 10, the coupler member 10 and the nut member 20 and the screw reinforcement members 1 and 3 is also prevented.
