상기한 구성에서, 본 발명의 커플링 하우징(10,30)은 원형단면 구조를 가지며, 내주면의 직경은 가운데에서 단부쪽 방향으로의 일정길이는 동일크기로 유지되어 일직선을 이루고, 나머지 단부쪽 방향으로의 길이는 단부쪽으로 갈수록 작아져 경사지게 형성된다. 즉 도 3c에 도시된 바와 같이, 커플링 하우징(10)의 내측면상에서 중앙부로부터 단부쪽으로 가는 길이 방향의 일정지점(P2)을 기준으로 중앙부쪽의 일정길이는 직선면으로, 단부쪽의 일정길이는 경사면으로 형성되며, 도면상에서의 경사각은 (a)로 도시하였다. 상기 경사각(a)은 철근 압착구(50)의 횡방향 이동에 따라 삽입된 철근이 철근 압착구(50)에 의해 충분히 고정될 수 있는 범위에서 설정되게 한다.In the above configuration, the coupling housing (10, 30) of the present invention has a circular cross-sectional structure, the diameter of the inner peripheral surface is a constant length from the center to the end direction is kept the same size to form a straight line, the remaining end direction The length of the furnace becomes smaller toward the end and is inclined. That is, as shown in Figure 3c, on the inner side of the coupling housing 10, a predetermined length of the central portion relative to the longitudinal point (P 2 ) in the longitudinal direction from the central portion to the end portion is a straight surface, constant on the end side The length is formed by the inclined surface, the inclination angle on the drawing is shown by (a). The inclination angle (a) is to be set in a range that can be sufficiently fixed by the reinforcing bar 50 is inserted in accordance with the transverse direction of the reinforcing bar 50.
또한, 철근 압착구(50)의 중심부에서 상기 지점 (P2)까지의 거리는 커플링 하우징(10)의 전체 길이의 대략 1/3 이 되도록 하는 것이 바람직하다.In addition, it is preferable that the distance from the center of the reinforcing crimp 50 to the point P 2 is approximately 1/3 of the total length of the coupling housing 10.
또한, 상기 커플링 하우징(10,30)은 두 개의 구조로 분할된 형태를 이루도록 하는 것이 바람직하데, 이는 커플링 하우징(10,30)의 내부에 철근 압착구(50)가 수용되기 때문이며, 두 개의 분할된 커플링 하우징(10,30)은 가운데 부위에서 상호 나사결합에 의해 결합되는 구조로 형성되게 한다. 즉, 도 3b에 도시된 바와 같이, 커플링 하우징(10,30)의 두 나사 결합부(15,35)에서 나사결합이 이루어지게 된다.In addition, the coupling housing (10,30) is preferably formed to be divided into two structures, because the reinforcing bar 50 is accommodated in the coupling housing (10,30), two The two divided coupling housings 10 and 30 are formed in a structure that is joined by mutual screwing at the center portion. That is, as shown in Figure 3b, the screw coupling is made in the two screw coupling portions (15,35) of the coupling housing (10,30).
한편, 상기 예시된 본 발명의 커플링 하우징(10,30)은 도 1에 도시된 일자형의 커플링 하우징(100) 이외에 도 5에 도시된 바와 같이, 십자형의 커플링 하우징(300), 기역자형 커플링 하우징(500), 티(T)자형 커플링 하우징(700)과 같은 형상으로 형성할 수 있으며, 상기 각 커플링 하우징의 형상에 따라 그 내부에 삽입되는 철근 압착구(50)의 수도 달라지게 된다.On the other hand, the illustrated coupling housings 10 and 30 of the present invention, in addition to the straight coupling housing 100 shown in Figure 1, as shown in Figure 5, the cross-shaped coupling housing 300, cross-type The coupling housing 500 and the T-shaped coupling housing 700 may be formed in the same shape, and the number of reinforcing crimp holes 50 inserted therein varies according to the shape of each coupling housing. You lose.
예컨대, 일자형의 커플링 하우징(100)과 기역자형 커플링 하우징(500)의 경우 내부에 삽입되는 철근 압착구(50)의 수는 두 개가 되고, 티자형의 경우 세 개, 십자형의 경우 네 개가 된다.For example, in the case of the straight coupling housing 100 and the non-reverse coupling housing 500, the number of the reinforcing crimp holes 50 inserted therein is two, three in the case of the T-shape, and four in the case of the cross. do.
본 발명의 커플링 하우징의 형상은 다양하게 변형될 수 있으나, 이하에서는 설명의 편의상 일자형의 커플링 하우징(10,30)의 경우를 중심으로 설명하기로 한다.The shape of the coupling housing of the present invention may be variously modified. Hereinafter, for convenience of description, the case of the straight coupling housings 10 and 30 will be described.
고정나사(70)가 삽입되는 나사 삽입구(81)는 본 발명의 커플링 하우징(10,30)의 중앙부에 형성되며, 상기 나사 삽입구(81)와 내주면은 나사산으로 형성되어 고정나사(70)의 회전에 의해 고정나사(7)의 종방향 이동이 이루어지게 된다.The screw insertion hole 81 into which the fixing screw 70 is inserted is formed at the center of the coupling housings 10 and 30 of the present invention, and the screw insertion hole 81 and the inner circumferential surface are formed of threads to form the fixing screw 70. Longitudinal movement of the set screw 7 is achieved by rotation.
한편, 커플링 하우징(10,30)에 형성된 나사 삽입구(81)는 도 3b에 도시된 바와 같이, 고정된 크기를 가지나, 그 하측의 나사 삽입구(83)는 철근 압착구(50)의 횡방향 슬라이딩 이동에 의해 크기가 변하게 된다.Meanwhile, the screw insertion holes 81 formed in the coupling housings 10 and 30 have a fixed size, as shown in FIG. 3B, but the lower screw insertion holes 83 are in the transverse direction of the reinforced crimping hole 50. The size is changed by the sliding movement.
본 발명의 상기 철근 압착구(50)는, 도 2a 및 도 3a 내지 도 3c에 도시된 바와 같이, 나사 삽입구(81)를 중심으로 서로 대향 해 있는 위치로 상기 커플링 하우징(10,30)의 내부에 삽입된다.The reinforcing bar 50 of the present invention, as shown in Figures 2a and 3a to 3c, of the coupling housing (10, 30) in a position facing each other with respect to the screw insertion hole 81 It is inserted inside.
즉, 본 발명의 철근 압착구(50)는 커플링 하우징(10,30)의 내부에서 서로 대향 해 있는 위치에 설치되어 있지만 각 철근 압착구(50)는 동일한 구조를 이룬다.That is, although the reinforcing bar 50 of the present invention is installed at positions facing each other inside the coupling housings 10 and 30, each of the reinforcing bar 50 forms the same structure.
즉, 본 발명의 철근 압착구(50)는 고정나사(70)와 경사지게 접촉하는 중심부(51)와, 상기 중심부(51)로부터 바깥쪽 단부 부위로 연장되어 나오며 둘레를 따라 일정 간격으로 이격된 압착 날개부(53,55)와, 상기 각 압착 날개부(53,55)의 내측면상에 형성된 고정돌기(53a,55a)를 포함하는 구성으로 이루어진다.That is, the reinforcing bar 50 of the present invention is a central portion 51 inclined contact with the fixing screw 70, and the pressing portion is extended to the outer end portion from the central portion 51 and spaced apart at regular intervals along the circumference It comprises a wing portion (53, 55) and the fixing projections (53a, 55a) formed on the inner surface of each of the crimping wing portions (53, 55).
본 발명의 상기 철근 압착구(50)의 각 압착 날개부(53,55)에 있어서 외측면부는 길이방향의 일정지점(도 3c의 P1)을 기준으로 중심부측의 길이는 직선면으로, 단부측의 길이는 경사면으로 형성된다. 이는 커플링 하우징(10,30)의 내주면이 일정 지점(도 3c의 P2)을 기준으로 중심부측의 길이는 직선면으로, 단부측의 바깥측 길이는 경사면으로 형성되어 있으므로, 이에 대응하여 접촉하는 철근 압착구(50)의 해당부분도 동일한 구조로 형성되도록 한다. In the crimping wings 53 and 55 of the reinforced crimping tool 50 of the present invention, the outer surface portion has a length at the center side on the basis of a predetermined point in the longitudinal direction (P1 in FIG. The length of is formed into the inclined surface. Since the inner circumferential surfaces of the coupling housings 10 and 30 are formed at a central point on the basis of a predetermined point (P2 in FIG. 3C), the length on the center side is formed on the straight side, and the length on the outer side on the end side is formed on the inclined surface. The corresponding portion of the reinforcing bar 50 is formed to have the same structure.
이는 커플링 하우징(10,30)의 내부에 삽입된 철근 압착구(50)가 횡방향으로 슬라이딩 이동할 경우 철근 압착구(50)의 외측면에 가해지는 압력이 동일하게 작용하도록 하기 위함이다.This is to ensure that the pressure applied to the outer surface of the reinforcing bar 50 when the reinforcing bar 50 inserted in the coupling housing (10,30) sliding movement in the transverse direction to act the same.
이를 위해, 도 3c에 도시된 바와 같이, 철근 압착구(50)의 전체 길이에 있어서, 중심부(51)로부터 중간의 일정 지점(P1)까지의 길이(ℓ1)는 일직선으로 되고, 상기 지점(P1)에서 단부측의 바깥까지의 길이(ℓ2)는 철근 압착구(50)의 직경이 작아져 경사진 구조를 이룬다. 즉 커플링 하우징(50)의 내주면의 직경이 바깥쪽 단부측으로 갈수록 좁아지므로 이에 대응하여 그 내측에 위치한 철근 압착구(50)의 외측면의 직경도 상기 지점(P1)으로부터 점진적으로 작아지도록 하여 철근 압착구(50)의 횡방향 슬라이딩 이동에 따라 철근 압착구(50)에 인가되는 압력이 균일하게 작용되도록 한다.To this end, as shown in FIG. 3C, in the entire length of the reinforcing bar 50, the length L1 from the central part 51 to a certain point P1 in the middle becomes a straight line, and the point P1. The length (L2) from the end side to the outside of the end side is smaller than the diameter of the reinforcing bar 50 to form an inclined structure. That is, since the diameter of the inner circumferential surface of the coupling housing 50 becomes narrower toward the outer end side, the diameter of the outer surface of the rebar crimp 50 located therein also gradually decreases from the point P1 correspondingly. The pressure applied to the reinforcing bar 50 according to the lateral sliding movement of the crimp 50 is to be uniformly applied.
또한, 본 발명의 상기 철근 압착구(50)의 중심부(51)에 있어서, 상측의 일부는 경사면(51a)으로 형성되고, 그 하부는 일직선면(51b)으로 형성되게 한다. 이에 의해 고정나사(70)가 커플링 하우징(10,30)의 고정나사 삽입구(81)로 삽입되면 고정나사의 하부 경사부(도 2b의 73)가 철근 압착구 중심부(51)의 상부 경사면(51b)에 접촉하여 철근 압착구(50)를 횡방향으로 이동시키게 된다. 즉, 고정나사(70)의 하향 이동하는 거리에 따라 철근 압착구(50)는 횡방향(길이 방향)으로 이동이 이루어지게 된다.In addition, in the central portion 51 of the reinforcing bar crimp 50 of the present invention, a portion of the upper side is formed by the inclined surface 51a, and the lower portion thereof is formed by the straight surface 51b. As a result, when the fixing screw 70 is inserted into the fixing screw insertion hole 81 of the coupling housings 10 and 30, the lower inclined portion (73 in FIG. 2B) of the fixing screw is the upper inclined surface of the reinforcing crimp center 51. 51b) to move the reinforcing bar 50 in the lateral direction. That is, the reinforcing bar 50 is moved in the horizontal direction (length direction) according to the downward movement distance of the fixing screw 70.
한편, 종방향으로 이동하는 고정나사(70)의 하부는 서로 대향 해 있는 두 개의 철근 압착구(50)의 중심부에 동시에 접촉하도록 구성되어 있어 두 개의 철근 압착구(50)는 함께 이동하게 된다.On the other hand, the lower portion of the fixing screw 70 to move in the longitudinal direction is configured to contact the center of the two reinforcing crimp 50 facing each other at the same time so that the two reinforcing crimp 50 is moved together.

한편, 도 4는 본 발명의 철근 이음장치에 철근이 결합된 상태의 사시도이다.On the other hand, Figure 4 is a perspective view of the reinforcing bar is coupled to the rebar joint of the present invention.
도시된 바와 같이, 본 발명의 철근 이음장치(100)에 연결된 철근(200a,220b)이 커플링 하우징(10,30)에 삽입되며, 고정나사(70)의 삽입에 의해 이루어진다. 도시된 도면에서는, 고정나사(70)가 상부로 돌출되어 있으나, 철근의 이음이 완료되는 상태에서는 고정나사(70)가 커플링 하우징(10,30)의 내부로 완전히 삽입되어 상부면이 평면을 이루게 된다.As shown, the reinforcing bars (200a, 220b) connected to the reinforcing bar coupling device 100 of the present invention is inserted into the coupling housing (10, 30), it is made by the insertion of the fixing screw (70). Although the fixing screw 70 protrudes upward in the drawing, the fixing screw 70 is completely inserted into the coupling housings 10 and 30 in the state where the reinforcing of the reinforcing bar is completed. Is achieved.
상기와 같이 구성된 본 발명의 철근 이음장치에 있어서의 작동에 대해 이하에서 설명하면 다음과 같다.The operation in the rebar joint device of the present invention configured as described above will be described below.
먼저, 상호 연결하고자 하는 철근(200a,200b)의 일측 단부를 커플링 하우징(10,30)의 단부측 철근 삽입구(12,32)에 삽입한다. 이때 철근(200a,200b)을 삽입할 시에는 커플링 하우징(10,30)의 내부에 함께 설치되어 있는 철근 압착구(50)의 중심부(51)에 이르기까지 충분히 삽입하도록 한다.First, one end of the reinforcing bars 200a and 200b to be interconnected is inserted into the end reinforcing bars 12 and 32 of the coupling housings 10 and 30. At this time, when inserting the reinforcing bars (200a, 200b) to be fully inserted up to the center 51 of the reinforcing bar 50 is installed in the coupling housing (10,30).
이 후 커플링 하우징(10,30)의 중심부에 형성된 고정나사 삽입구(81) 측으로 고정나사(70)를 회전시켜 삽입시킨다. 고정나사(70)의 종방향 삽입이 이루어지면 고정나사의 하부 경사부(73)가 철근 압착구 중심부(51)의 상부 경사면(51a)과 접촉하여 철근 압착구(50)를 횡방향으로 밀어내게 된다. 이때 철근 압착구(50)의 설치된 수만큼 동시에 접촉이 이루어지므로 다수의 철근 압착구(50)는 함께 이동이 이루어진다.After that, the fixing screw 70 is rotated and inserted into the fixing screw insertion hole 81 formed at the center of the coupling housing 10 or 30. When the fixing screw 70 is inserted in the longitudinal direction, the lower inclined portion 73 of the fixing screw contacts the upper inclined surface 51a of the reinforcing crimp center 51 to push the reinforcing crimp 50 laterally. do. At this time, since the contact is made at the same time as the installed number of the reinforcing bar 50, the plurality of reinforcing bar 50 is moved together.
철근 압착구(50)의 횡방향 슬라이딩 이동이 일정거리만큼 이루어지면 커플링 하우징(10,30)의 내주면이 경사져 있으므로, 횡방향으로 수평하게 이동하는 철근 압착구(50)의 작용에 의해 철근 압착구(50)의 압착 날개부(53,55)는 반경방향으로 힘을 받게 되고, 이 힘에 의해 철근 압착구(50)의 압착 날개부(53,55)는 내부 삽입된 연결하고자 하는 철근의 외측면을 압박하여 고정시키게 된다. 이때 상기 철근 압착구(50)의 압착 날개부(53,55)의 내측면에는 고정돌기(53a,55a)가 형성되어 있어 압착된 상태를 견고하게 유지하게 된다. 이때 상기 고정돌기(53a,55a)는 뾰족한 핀 형태로 할 수도 있으나 측방향으로 일정 길이를 갖도록 하여 충분한 강성을 유지할 수 있도록 하는 것이 바람직하다.Since the inner peripheral surfaces of the coupling housings 10 and 30 are inclined when the transverse sliding movement of the reinforcing bar 50 is made by a predetermined distance, the reinforcing crimp is operated by the action of the reinforcing bar 50 that moves horizontally in the horizontal direction. The crimping wings 53 and 55 of the sphere 50 are subjected to a radial force, and by this force, the crimping wings 53 and 55 of the rebar crimp 50 are inserted into the reinforcing bars to be inserted. The outer surface is pressed and fixed. At this time, the fixing projections 53a and 55a are formed on the inner surfaces of the crimping wings 53 and 55 of the reinforcing bar 50 to maintain the compressed state firmly. In this case, the fixing protrusions 53a and 55a may be in the form of pointed pins, but preferably have a predetermined length in the lateral direction so as to maintain sufficient rigidity.
도 2c는 도 1의 커플링 하우징의 중심부에 삽입되는 고정나사의 다른 예를 보인 사시도이며, 도 3d는 도 2c에 도시된 다른 실시 예에 따른 고정나사의 체결 전 상태를 도시하는 철근 이음장치의 내부 결합 구조를 단면도이며, 도 3e는 도 2c에 도시된 다른 실시 예에 따른 고정나사의 체결 후 상태를 도시하는 철근 이음장치의 내부 결합 구조를 단면도이다. FIG. 2C is a perspective view illustrating another example of a fixing screw inserted into the center of the coupling housing of FIG. 1, and FIG. 3D is a view illustrating a state before the fixing screw is fastened according to another embodiment illustrated in FIG. 2C. Figure 3e is a cross-sectional view of the internal coupling structure, Figure 3c is a cross-sectional view of the internal coupling structure of the reinforcing bar connecting device showing a state after the fastening of the fixing screw according to another embodiment shown in FIG.
도 2c를 참조하면, 본 발명의 바람직한 실시 예에 따른 철근 이음장치의 커플링 하우징의 중심부에 삽입되는 고정나사(70a)는, 외주면에 나사선이 형성되며, 내부에 형성된 중공부에 소정 형상의 렌치홈이 형성된 몸체(71a)와, 렌티홈이 형성된 몸체(71a)의 상단부에 몸체(71a)의 직경 보다 상대적으로 두껍게 형성된 헤드부(72a)와, 몸체(71a)의 하단부에 하단방향으로 갈수록 그 직경이 작게 형성되는 경사 마감부(74a)와, 몸체(71a)의 하단부에 착탈가능하게 체결되어 몸체(71a)의 외주면에 형성된 나사선을 따라 종으로 이동하는 너트(73a)로 이루어진다. Referring to Figure 2c, the fixing screw (70a) is inserted into the center of the coupling housing of the reinforcing bar according to the preferred embodiment of the present invention, the screw thread is formed on the outer peripheral surface, a wrench of a predetermined shape in the hollow formed therein The grooved body 71a, the head portion 72a formed relatively thicker than the diameter of the body 71a at the upper end of the body 71a having the lent groove, and the lower portion of the body 71a toward the lower direction. It consists of an inclined finish portion 74a having a small diameter, and a nut 73a which is detachably fastened to the lower end of the body 71a and moves longitudinally along a screw line formed on the outer circumferential surface of the body 71a.
이와 같은 다른 형상의 고정나사(70a)가 적용되는 철근 이음 장치에 적용되는 경우, 커플링 하우징(10,30)과 철근 압착구(50)의 형상이 도 3d에 도시된 바와 같이, 부분적으로 변경될 수 있으며, 이에 따라 철근을 잇는 동작도 다소 달라질 것이다. When the fixing screw 70a of such another shape is applied to the rebar joint apparatus to which the fixing screw 70a is applied, the shapes of the coupling housings 10 and 30 and the rebar crimp 50 are partially changed, as shown in FIG. 3D. As a result, the operation of connecting the rebar will be somewhat different.
이하에서 도 1 내지 도 2b 및 도 3a 내지 도 3c를 참조하여 설명한 본 발명의 철근 이음 장치의 구성 및 동작과 동일하거나 중복되는 부분은 생략하고 도 2c, 도 3d 및 도 3e를 중심으로 상이한 부분을 중점으로 설명한다. Hereinafter, the same or duplicate parts as those of the structure and operation of the rebar joint apparatus of the present invention described with reference to FIGS. 1 to 2B and 3A to 3C will be omitted, and different portions will be described with reference to FIGS. 2C, 3D, and 3E. Explain with emphasis.
먼저, 고정 나사(70a)가 삽입되는 나사 삽입구(81)와 접하는 한 쌍의 커플링 하우징(10,30)이 서로 접하는 중앙부에는 고정 나사(70a)의 헤드부(72a)가 걸림 및 지지되면서 헤드부(72)의 회전이 가능한 공간이 형성되도록 단턱부(52)가 각각 형성된다. 또한, 나사 삽입구(81)의 내주면은 고정 나사(70a)의 외주면에 형성된 나사와 나사 결합되도록 나사선으로 형성되어, 고정나사(70a)가 좌우방향으로 회전되는 경우, 고정 나사(70a)가 철근 압착구(50)를 압착하거나 압착을 풀어주기 위하여 종방향 이동될 수 있다. First, the head portion 72a of the fixing screw 70a is caught and supported in the center portion where the pair of coupling housings 10 and 30 contacting the screw insertion hole 81 into which the fixing screw 70a is inserted are held and supported. The stepped portions 52 are formed to form spaces in which the portions 72 can be rotated. In addition, the inner circumferential surface of the screw insertion port 81 is formed with a screw line so as to be screwed with the screw formed on the outer circumferential surface of the fixing screw 70a, and when the fixing screw 70a is rotated in the left and right direction, the fixing screw 70a is crimped to the rebar. The sphere 50 can be squeezed or moved longitudinally to release the squeeze.
또한, 고정 나사(70a)가 삽입되는 커플링 하우징(10)의 하단부분에는 고정 나사(70a)의 경사 마감부(74a)의 회전운동이 가능하도록 역삼각형의 홈(54)이 형성되는 것이 바람직하다. In addition, it is preferable that an inverted triangular groove 54 is formed at the lower end of the coupling housing 10 into which the fixing screw 70a is inserted to enable the rotational movement of the inclined finish portion 74a of the fixing screw 70a. Do.
한편, 각각의 철근 압착구(50)의 중심부(51)는 고정나사(70a)의 외부에 형성된 나사선과 나사 결합되며, 하단부에 고정 나사(70a)에 체결된 너트(73a)의 종방향 이동이 가능하도록 마름모 형상의 내측 공간이 형성되는 것이 바람직하다. On the other hand, the center 51 of each of the reinforced crimping port 50 is screwed with a screw line formed on the outside of the fixing screw 70a, the longitudinal movement of the nut 73a fastened to the fixing screw 70a at the lower end is It is preferable that a rhombic inner space is formed so as to be possible.
이에 따라, 작업자가 고정 나사(70a)의 내부에 형성된 렌치홈에 렌치를 끼운 상태에서 철근 압착구(50)를 압착하는 방향으로 회전시킬 경우, 도 3e에 도시된 바와 같이, 고정 나사(70a)에 체결된 너트(73a)의 직경이 고정 나사(70a)의 몸체(71a)의 직경 보다 상대적으로 크기 때문에, 고정 나사(70a)에 체결된 너트(73a)가 마름모 형상의 내측 공간에서 상부 방향으로 이동된다. 따라서, 고정 나사(70a)의 헤드부(72a)와 너트(73a) 사이에 위치한 철근 압착구(50)는 고정 나사(70a)의 조임의 세기에 비례하게 압착될 수 있다.Accordingly, when the operator rotates in the direction of pressing the reinforcing bar 50 when the wrench is inserted into the wrench groove formed in the fixing screw 70a, as shown in Figure 3e, the fixing screw 70a Since the diameter of the nut 73a fastened to the screw 73a is relatively larger than the diameter of the body 71a of the fixing screw 70a, the nut 73a fastened to the fixing screw 70a is directed upward in the rhombic inner space. Is moved. Therefore, the reinforcing crimp 50 located between the head portion 72a of the fixing screw 70a and the nut 73a may be compressed in proportion to the strength of tightening of the fixing screw 70a.
이상에서 설명한 본 발명의 다른 실시 예에 따른 고정 나사(70a)는 도 1 내지 도 2b 및 도 3a 내지 도 3c에 도시된 고정 나사(70)의 동작과는 반대 개념으로 동작되는 것임을 알 수 있다.It can be seen that the fixing screw 70a according to another embodiment of the present invention described above is operated in a concept opposite to that of the fixing screw 70 illustrated in FIGS. 1 to 2b and 3a to 3c.
