Description
본 발명은 일직선상에 배치되지 않은 2개의 철근을 상호 연결할 수 있도록 된 새로운 구조의 PC블럭 또는 콘크리트용 철근 편심연결구와 이를 이용한 철근연결방법에 관한 것이다.The present invention relates to a rebar eccentric connector for a PC block or concrete for a new structure that is capable of interconnecting two reinforcing bars not arranged in a straight line, and a method of connecting the reinforcing bars using the same.
일반적으로, 공사형장에서 철근 콘크리트 구조물을 만들 때는, 거푸집을 설치하고, 상기 거푸집의 내부에 철근을 배근한 후, 거푸집의 내부에 콘크리트를 타설 및 경화시켜 시공하였다.In general, when making a reinforced concrete structure in a construction site, install the formwork, reinforcing the reinforcement in the interior of the formwork, and then placed and hardened concrete in the formwork was constructed.
이때, 상기 철근은 일정한 길이로 제작됨으로, 길이가 긴 철근이 필요할 때는 등록특허 10-0411242호나, 공개특허 10-2002-0081966호를 비롯한 다수의 선행문건에 나타난 철근연결구를 이용하여 철근을 상호 연결하여 사용하고 있다.In this case, since the rebar is manufactured to a certain length, when a long rebar is required, the reinforcing bars are interconnected using reinforcing bars shown in a number of preceding documents, including Patent Publication No. 10-0411242 or Patent Publication No. 10-2002-0081966. I use it.
그런데, 이러한 방법으로 구조물을 제작할 경우, 시간이 많이 소요됨으로, 최근에는, 공장에서 형틀의 내부에 철근을 배근한 후 형틀의 콘크리트를 주입 및 경화시켜 제작한 PC블록을 이용하여 건축물의 벽체나 슬라브를 시공하는 방식이 널리 이용되고 있다.By the way, when manufacturing the structure in this way, it takes a lot of time, recently, in the factory reinforcing the reinforcing bar in the interior of the mold using a PC block produced by injecting and hardening the concrete of the mold wall or slab of the building Construction method is widely used.
이와 같이, PC블록을 이용할 경우, 철근의 배근이나 콘크리트의 타설 및 경화에 소요되는 시간을 줄일 수 있음으로, 콘크리트 구조물의 건축시간을 획기적으로 줄일 수 있는 장점이 있다.As such, when using the PC block, it is possible to reduce the time required for reinforcement of the reinforcement or concrete pouring and hardening, there is an advantage that can significantly reduce the construction time of the concrete structure.
한편, 이와 같이 제작된 PC블록은 양측에 철근이 측방향으로 연장되도록 구비되어, 상기 철근을 상호 용접결합함으로서, 여러개의 PC블록이 상호 견고하게 고정되도록 하고 있다.On the other hand, the produced PC block is provided on both sides so that the reinforcing bars extend laterally, by welding the reinforcing bars to each other, so that several PC blocks are firmly fixed to each other.
그러나, 이와 같이, 현장에서 PC블록의 측방향으로 돌출된 철근을 상호 용접결합할 경우, 시간이 많이 소요될 뿐 아니라, 용접기에 의한 안전사고가 발생될 수 있는 문제점이 발생되었다.However, as described above, when welding the reinforcing bars of the PC block in the lateral direction in the field, it takes not only a lot of time, but also a problem that may cause a safety accident by the welder.
따라서, 최근에는 전술한 바와 같이, 철근연결구를 이용하여 각각의 PC블록의 둘레면으로 돌출된 철근을 상호 연결하는 방법이 연구되고 있다.Therefore, recently, as described above, a method of interconnecting reinforcing bars protruding to the circumferential surface of each PC block using reinforcing bar connectors has been studied.
그런데, 이러한 철근연결구는 상기 철근이 상호 일직선상에 배치되었을 때만 연결할 수 있다.However, these reinforcing bar connectors can be connected only when the reinforcing bars are arranged in a line with each other.
그러나, 상기 PC블록의 양측으로 연장된 철근은 PC블록의 제조공정상 정확하게 위치되지 못하게 되는 경우가 발생된다.However, rebars extending to both sides of the PC block may not be accurately positioned in the manufacturing process of the PC block.
따라서, 2개의 PC블록의 측면으로 연장된 철근을 상호 연결할 때, 각 PC블록의 측면으로 연장된 철근이 일직선상에 위치되지 못하고, 이에 따라, 종래의 철근연결구를 이용하여 PC블록의 철근을 상호 연결하는 것이 매우 제한적이게 되는 문제점이 발생되었다.Therefore, when connecting the reinforcing bars extending to the sides of the two PC blocks, the reinforcing bars extending to the sides of each PC block are not positioned in a straight line. The problem arises that the connection becomes very limited.
이러한 문제점은 전술한 PC블록의 철근을 연결할 때 뿐 아니라, 외부에서 미리 조립된 상태로 거푸집의 내부에 설치되는 철근구조물을, 상기 철근연결구를 이용하여 상호 연결할 때도 동일하게 발생되었다.This problem has occurred not only when connecting the reinforcing bars of the PC block described above, but also when connecting the reinforcing structures installed inside the formwork in a pre-assembled state from the outside using the reinforcing connector.
따라서, 이러한 문제점을 해결할 수 있는 새로운 방법이 필요하게 되었다.Therefore, there is a need for a new method to solve this problem.
본 발명은 상기의 문제점을 해결하기 위한 것으로서, 일직선상에 배치되지 않은 2개의 철근을 상호 연결할 수 있도록 된 새로운 구조의 PC블럭 또는 콘크리트용 철근 편심연결구와 이를 이용한 철근연결방법을 제공함에 그 목적이 있다.The present invention is to solve the above problems, to provide a new structure of the PC block or concrete reinforced eccentric connector and the method of connecting the reinforcement using the same structure that can be connected to the two reinforcing bar not arranged in a straight line have.

이와 같이 구성된 PC블럭 또는 콘크리트용 철근 편심연결구는 제1 철근(1)의 선단부에 고정결합되는 고정블록(10)과, 상기 제1 고정블록(10)에 고정결합되는 지지통체(20)와, 상기 지지통체(20)의 내부에 회전가능하게 결합되며 제2 철근(2)의 선단부가 고정결합되는 회전블록(30)으로 구성되며, 상기 제1 철근(1)과 제2 철근(2)은 상기 고정블록(10)과 회전블록(30)에 편심을 이루도록 결합된다.PC block or concrete reinforced eccentric connector configured as described above is a fixed block 10 is fixedly coupled to the front end of the first reinforcing bar (1), the support cylinder 20 fixedly coupled to the first fixed block (10), Rotatingly coupled to the inside of the support cylinder 20 and composed of a rotating block 30 is fixed to the front end of the second reinforcement (2), the first reinforcement (1) and the second reinforcement (2) The fixed block 10 and the rotary block 30 are coupled to form an eccentricity.
특히, 상기 제1 및 제2 철근(1,2)의 선단부에는 수나사(1a,2a)가 형성되며, 상기 고정블록(10)에는 둘레면에 수나사(11a)가 형성된 원형의 결합부(11)가 형성되고, 상기 고정블록(10)에는 상기 제1 철근(1)의 선단부가 나사결합되는 결합공(12)이 상기 결합부(11)와 편심을 이루도록 형성되며, 상기 지지통체(20)는 전후방향으로 연장되어 내부에 상기 회전블록(30)이 삽입되는 관체형상으로 구성되고, 상기 지지통체(20)의 기단부와 선단부의 내주면에는 상기 회전블록(30)이 걸리는 걸림턱(22)과 상기 결합부(11)의 외측에 나사결합되는 암나사(21)가 각각 형성되며, 상기 회전블록(30)은 전후방향으로 연장되며 외경이 상기 지지통체(20)의 내경에 대응되는 원형단관 형태로 구성되며 상기 제2 철근(2)의 선단부가 나사결합되는 결합공(31)이 편심을 이루면서 전후면을 관통하도록 형성되어, 상기 고정블록(10)과 회전블록(30)을 회전시켜 상기 결합공(12,31)의 간격을 조절할 수 있다.In particular, male threads (1a, 2a) are formed on the front end portions of the first and second reinforcing bars (1, 2), the fixing block 10 has a circular coupling portion 11 formed with a male screw (11a) on the circumferential surface Is formed, the fixing block 10 is formed so that the coupling hole 12, the leading end of the first reinforcing bar 1 is screwed to form an eccentric with the coupling portion 11, the support cylinder 20 is It is formed in a tubular shape extending in the front and rear direction and the rotary block 30 is inserted therein, and the locking step 22 and the engaging block 22 is caught on the inner circumferential surface of the support cylinder 20 and the distal end of the support cylinder 20. Female threads 21 are screwed to the outside of the coupling portion 11 is formed, respectively, the rotary block 30 extends in the front and rear direction and the outer diameter is configured in the form of a circular end pipe corresponding to the inner diameter of the support cylinder 20 The penetrating hole 31 through which the distal end of the second rebar 2 is screwed is eccentric and penetrates the front and rear surfaces. It is formed so as to, by rotating the fixing block 10 and the rotation block 30 may adjust the interval of the engaging hole (12,31).
따라서, 상기 제1 및 제2 철근(1,2)이 일직선상에 위치되지 않을 경우, 상기 고정블록(10)과 회전블록(30)을 회전시켜 상기 결합공(12,31)의 간격을 제1 및 제2 철근(1,2)의 간격에 맞도록 조절함으로써, 일직선상에 위치되지 않은 2개의 철근(1,2)을 간편하면서 견고하게 상호 연결할 수 있는 장점이 있다.Therefore, when the first and second reinforcing bars (1, 2) are not located in a straight line, the fixing block 10 and the rotating block 30 by rotating the gap between the coupling holes (12, 31) By adjusting to fit the interval between the first and second reinforcing bars (1, 2), there is an advantage that can be easily and firmly interconnected two reinforcing bars (1,2) not located in a straight line.
본 실시예의 경우, 상기 PC블럭 또는 콘크리트용 철근 편심연결구는 PC블록의 측면에서 서로 마주보도록 연장된 제1 및 제2 철근(1,2)을 상호 연결하는데 적용되는 것을 예시하였으나, 본 발명에 따른 PC블럭 또는 콘크리트용 철근 편심연결구는 모든 종류의 철근을 상호 연결하는데 적용될 수 있다.In the present embodiment, the PC block or reinforced reinforcing eccentric connector for concrete is applied to interconnect the first and second reinforcing bars (1, 2) extended to face each other at the side of the PC block, according to the present invention Rebar eccentric connectors for PC blocks or concrete can be applied to interconnect all types of rebars.
도 6 내지 도 12는 본 발명에 따른 다른 실시예를 도시한 것으로, 상기 제2 철근(2)의 선단부에 형성된 수나사(2a) 및 회전블록(30)의 결합공(31)에 형성된 암나사(31a)와, 상기 결합부(11)에 형성된 수나사(11a) 및 지지통체(20)의 암나사(21)는 나사선의 방향이 서로 반대로 구성된다.6 to 12 show another embodiment according to the present invention, a male screw 2a formed at the distal end of the second reinforcing bar 2 and a female screw 31a formed at the coupling hole 31 of the rotary block 30. ) And the female screw 21 of the support member 20 and the male screw 11a formed in the coupling portion 11 are configured in opposite directions to each other.
바람직하게는, 상기 제2 철근(2)의 선단부에 형성된 수나사(2a) 및 회전블록(30)의 결합공(31)에 형성된 암나사(31a)는 우나사로 구성된다.Preferably, the male screw 2a formed at the distal end of the second reinforcing bar 2 and the female screw 31a formed at the coupling hole 31 of the rotary block 30 are constituted by a right screw.
따라서, 상기 회전블록(30)을 우측, 즉 시계방향으로 회전시키면 상기 회전블록(30)이 상기 제2 철근(2)의 선단부로 전진된다.Accordingly, when the rotary block 30 is rotated to the right, that is, clockwise, the rotary block 30 is advanced to the tip of the second reinforcing bar 2.
그리고, 상기 결합부(11)에 형성된 수나사(11a) 및 지지통체(20)의 암나사(21)는 좌나사로 구성된다.In addition, the male screw 11a of the coupling portion 11 and the female screw 21 of the support cylinder 20 are composed of a left screw.
따라서, 상기 지지통체(20)를 좌측, 즉 반시계방향으로 회전시키면 상기 지지통체(20)가 상기 고정블록(10)의 결합부(11)에 나사결합된다.Therefore, when the support cylinder 20 is rotated to the left, that is, counterclockwise, the support cylinder 20 is screwed to the engaging portion 11 of the fixed block 10.
그리고, 상기 회전블록(30)의 외주면에는 상기 지지통체(20)의 내주면에 밀착되는 마찰부재(32)가 구비된다.And, the outer peripheral surface of the rotary block 30 is provided with a friction member 32 in close contact with the inner peripheral surface of the support cylinder 20.
상기 마찰부재(32)는 마찰력이 높은 고무재질로 구성된다.The friction member 32 is made of a rubber material of high friction.
이와 같이 구성된 PC블럭 또는 콘크리트용 철근 편심연결구는 도 8에 도시한 바와 같이, 상기 지지통체(20)의 내부에 구비된 회전블록(30)에 상기 제2 철근(2)을 나사결합한 상태에서, 상기 지지통체(20)를 회전시키면 상기 마찰부재(32)에 의해 발생되는 마찰에 의해 상기 회전블록(30)이 회전되면서 상기 제2 철근(2)의 수나사(2a)를 따라 전후진된다.As shown in FIG. 8, the PC block or the concrete reinforced eccentric connector configured as described above, in the state in which the second reinforcing bar 2 is screwed to the rotary block 30 provided in the support cylinder 20, When the support cylinder 20 is rotated, the rotary block 30 is rotated by the friction generated by the friction member 32, and is moved back and forth along the male screw 2a of the second reinforcing bar 2.
따라서, PC블럭 또는 콘크리트용 철근 편심연결구를 이용하여 제1 및 제2 철근(1,2)을 상호 연결할 때, 작업자가 실수로 상기 회전블록(30)을 과도하게 조이더라도 손쉽게 상기 제1 및 제2 철근(1,2)을 연결할 수 있다.Therefore, when the first and second reinforcing bars (1, 2) are interconnected by using a PC block or rebar eccentric connector for concrete, even if the worker accidentally excessively tightens the rotary block 30, the first and second 2 Reinforcing bars (1, 2) can be connected.
즉, 상기 PC블럭 또는 콘크리트용 철근 편심연결구를 이용하여 제1 및 제2 철근(1,2)을 상호 연결하기 위해서는 도 1에 도시한 바와 같이, 상기 회전블록(30)이 제2 철근(2)의 수나사(2a)의 중간부에 위치되도록 조여져야 한다.That is, in order to interconnect the first and second reinforcing bars (1, 2) by using the PC block or reinforcing bar eccentric connector for concrete, as shown in Figure 1, the rotary block 30 is a second reinforcing bar (2) ) To be located in the middle of the male screw (2a).
이때, 작업자의 실수로 도 9에 도시한 바와 같이, 상기 회전블록(30)이 제2 철근(2)의 수나사(2a)의 내측으로 과도하게 조여질 경우, 도 10에 도시한 바와 같이, 상기 회전블록(30)에 걸려 지지통체(20)가 상기 고정블록(10)의 결합부(11)에 결합되지 못한다.At this time, as shown in FIG. 9 by mistake of the operator, when the rotary block 30 is excessively tightened to the inside of the male screw (2a) of the second reinforcing bar 2, as shown in FIG. The support cylinder 20 is caught by the rotary block 30 and cannot be coupled to the coupling part 11 of the fixed block 10.
이러한 경우, 도 10 및 도 11에 도시한 바와 같이, 작업자가 상기 지지통체(20)를 우측, 즉, 시계방향으로 회전시키면 상기 마찰부재(32)의 마찰력에 의해 상기 회전블록(30)이 함께 시계방향으로 회전되면서 상기 제2 철근(2)의 수나사(2a)를 따라 전진된다.In this case, as shown in FIGS. 10 and 11, when the operator rotates the support cylinder 20 to the right, that is, clockwise, the rotary block 30 is brought together by the frictional force of the friction member 32. It is advanced along the male screw 2a of the second reinforcing bar 2 while being rotated clockwise.
이때, 상기 지지통체(20)에 형성된 암나사(21)는 좌나사임으로, 지지통체(20)를 시계방향으로 회전시키더라도 지지통체(20)가 상기 고정블록(10)의 결합부(11)에 결합되지 않는다.At this time, the female screw 21 formed on the support cylinder 20 is a left-hand screw, even if the support cylinder 20 is rotated in the clockwise direction, the support cylinder 20 is coupled to the coupling portion 11 of the fixed block 10. Not combined.
그리고, 상기 회전블록(30)이 충분히 전진된 상태에서, 도 12에 도시한 바와 같이, 작업자가 상기 지지통체(20)를 좌측, 즉 반시계방향으로 회전시키면, 상기 지지통체(20)가 상기 고정부에 나사결합되어 제1 및 제2 철근(1,2)이 상호 연결된다.And, in the state that the rotary block 30 is sufficiently advanced, as shown in Figure 12, when the operator rotates the support cylinder 20 to the left, that is, counterclockwise, the support cylinder 20 is The first and second reinforcing bars 1 and 2 are interconnected by being screwed to the fixing part.
이때, 상기 지지통체(20)를 반시계방향으로 회전시킴에 따라, 상기 회전블록(30) 역시 반시계방향으로 회전되어 제2 철근(2)쪽으로 후퇴될 수 있으나, 상기 지지통체(20)를 반시계방향으로 회전시킬 경우 상기 지지통체(20)가 제1 철근(1)쪽으로 전진되면서 고정블록(10)에 나사결합됨으로, 상기 마찰부재(32)의 마찰력에 의해 상기 회전블록(30)을 제1 철근(1)쪽으로 밀어내는 힘이 발생되어, 상기 회전블록30)이 제2 철근(2)쪽으로 후퇴되지 못하도록 한다.In this case, as the support cylinder 20 is rotated counterclockwise, the rotary block 30 may also be rotated counterclockwise and retracted toward the second reinforcing bar 2, but the support cylinder 20 may be retracted. In the case of rotating in the counterclockwise direction, the support cylinder 20 is screwed to the fixed block 10 while being advanced toward the first reinforcing bar 1, thereby rotating the rotation block 30 by the frictional force of the friction member 32. A force pushing toward the first reinforcing bar 1 is generated to prevent the rotary block 30 from being retracted toward the second reinforcing bar 2.
따라서, 상기 지지통체(20)를 반시계방향으로 회전시킬 때는 회전블록(30)은 회전되지 않고 상기 지지통체(20)만 회전되면서 상기 결합부(11)에 결합된다.Therefore, when rotating the support cylinder 20 in the counterclockwise direction, the rotary block 30 is not rotated and is coupled to the coupling part 11 while only the support cylinder 20 is rotated.
따라서, 작업자가 상기 회전블록(30)을 과도하게 많이 조이더라도, 상기 지지통체(20)를 회전시켜 손쉽게 회전블록(30)의 위치를 조절할 수 있음으로, 사용이 더욱 편리한 장점이 있다.Therefore, even if the worker tightens the rotary block 30 excessively much, by rotating the support cylinder 20 can easily adjust the position of the rotary block 30, there is an advantage that it is more convenient to use.
본 발명은 일직선상에 배치되지 않은 2개의 철근을 상호 연결할 수 있도록 된 새로운 구조의 PC블럭 또는 콘크리트용 철근 편심연결구와 이를 이용한 철근연결방법 분야에 적용할 수 있다.The present invention can be applied to the field of rebar eccentric connector and a rebar connection method for the PC block or concrete of a new structure that can be connected to the two reinforcing bar not arranged in a straight line.
