[실시예]EXAMPLE

이하, 본 발명의 접속용 정착구 및 긴장재의 실시형태를 도면을 참조하여 상세히 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the connection anchorage and tension member of this invention is described in detail with reference to drawings.

먼저, 접속용 정착구에 대하여 설명하고, 그 다음에 긴장재에 대하여 설명한다.First, the connection fixing apparatus will be described, and then the tension member will be described.

도 1은 접속용 정착구의 단면도, 도 2는 다른 접속용 정착구의 단면도이다.1 is a cross-sectional view of a connecting fixing unit, and FIG. 2 is a cross-sectional view of another connecting fixing unit.

접속용 정착구(1)은 PC강재의 단부에 설치하여 그 접속을 용이하게 하는 것이며, 커플러(2)와 접속부재(3)으로 구성되어 있다.The connection fixing device 1 is provided at the end of the PC steel to facilitate the connection thereof, and is composed of a coupler 2 and a connection member 3.

커플러(2)는 PC강재의 앵커헤드나 접속부재(3)을 끼워 결합하는 결합구멍(4)를 구비하고, 이 결합구멍(4)의 내면에 암나사(5)가 만들어져 있다. 그리고, 결합구멍(4)의 한쪽으로 접속부재(3)이 비틀려 박혀 있다.The coupler 2 is provided with the engaging hole 4 which engages the anchor head and connection member 3 of PC steel, and the female screw 5 is made in the inner surface of this engaging hole 4. The connecting member 3 is twisted into one of the coupling holes 4.

접속부재(3)은 평행하는 두장의 판(6)이 자형으로 돌출형성되며, 선단부에 접속핀(7)이 설치되어 있다.The connecting member 3 has two parallel plates 6 Protrudingly shaped, the connecting pin 7 is provided at the tip.

그리고 두장의 판(6)사이에 접속하는 상대측의 접속부재가 삽입되어 접속핀(7)로 고정된다.Then, the connecting member on the opposite side to be connected between the two plates 6 is inserted and fixed with the connecting pin 7.

이 접속핀(7)은 한쪽의 저지판(8)이 나사(9)로 떼어내기를 할 수 있도록 되어 있으며, 이 나사(9)로 저지판(8)을 탈착할 수 있게 하므로서 접속핀(7)이 접속부재(3)으로부터 설치와 해제가 가능하도록 되어 있다.This connecting pin 7 allows one stop plate 8 to be detached with a screw 9, and the connecting pin 7 can be detached from the stop plate 8 with this screw 9. Is installed and released from the connecting member 3.

또, 접속핀(7)은 록너트(10)으로 커플러에 고정되어 있다.In addition, the connecting pin 7 is fixed to the coupler by the lock nut 10.

또, 접속용 정착구(1)을 PC강재의 단부에 설치한 경우에, PC강재의 단부를 누르는 록플레이트(11)이 결합구멍(4)에 비틀려 박혀 있다.In addition, in the case where the connection fixing tool 1 is provided at the end of the PC steel, the lock plate 11 for pressing the end of the PC steel is twisted in the engaging hole 4.

도 2는 다른 접속용 정착구(12)를 나타낸 것으로서, 접속부재(13)이 한장의 판(14)로 형성되어 있는 것 이외는 상기 접속용 정착구(1)과 동일한 구성이다.FIG. 2 shows another connection fixing tool 12, which has the same configuration as the connecting fixing device 1 except that the connecting member 13 is formed of a single plate 14. As shown in FIG.

이 경우는 접속하는 상대측의 접속부재가 두장의 판으로 자 형태로 형성되어 있다.In this case, the connecting member on the other side to be connected is made of two plates. It is formed in the shape of a ruler.

다음에, 상기의 접속용 정착구를 설치한 긴장재에 대하여 설명한다.Next, a tension member provided with the above-mentioned fixing anchor is described.

또한, 접속용 정착구에 대해서는 동일한 부호를 사용하여 설명한다.In addition, the connection fixing apparatus is demonstrated using the same code | symbol.

이 긴장재(15)는 도 6에 나타내는 바와 같은 서스펜션구조물(16)에 사용하는 것이며, 간단한 핀 접합이 될수 있도록 PC강재(17)의 양쪽단부에 접속용 정착구(1)이 설치되어 있다.This tension member 15 is used for the suspension structure 16 as shown in FIG. 6, and a connection fixing device 1 is provided at both ends of the PC steel 17 so that simple pin bonding can be achieved.

커플러(2)의 결합구멍(4)의 한쪽, 즉 후단측에는 앵커헤드(18)이 비틀려 박혀서 접속용 정착구(1)이 PC강재(17)의 단부에 설치되어 있다.The anchor head 18 is twisted into one of the coupling holes 4 of the coupler 2, i.e., the rear end side thereof, so that the connection fixing device 1 is provided at the end of the PC steel 17.

또, 커플러(2)의 결합구멍(4)의 다른 쪽에는 접속부재(3)이 비틀려 박히고, 록너트(10)으로 고정되어 있다.In addition, the connecting member 3 is twisted in the other side of the coupling hole 4 of the coupler 2, and is fixed by the lock nut 10. As shown in FIG.

상기 PC강재(17)은 피복(sheath)(19)로 복수의 꼬인 PC강선(20)이 다발로 묶여서 형성되며, 상기 꼬인 PC강선(20)이 앵커헤드(18)에 압착그립(21)로 고정되어 있다.The PC steel 17 is formed by sheathing a plurality of twisted PC steel wires 20 in bundles, and the twisted PC steel wires 20 are crimped grips 21 to the anchor head 18. It is fixed.

상기 피복(19)의 단부는 커플러(2)의 결합구멍(4)에 삽입되며, 그 외면에 감겨진 방수재(22)가 물의 침입을 방지하고 있다.The end of the sheath 19 is inserted into the coupling hole 4 of the coupler 2, and the waterproofing material 22 wound around its outer surface prevents water from entering.

또 앵커헤드 하면과 상기 피복선단부의 사이에는 실리콘고무등의 스페이서(23)이 끼워져 있으며, 압착그립(21)의 앞쪽으로 비틀어 박은 록플레이트(11)과 함께 꼬인 PC강선(20)의 이동으로 인한 파송을 방지하고 있다.In addition, a spacer 23, such as silicone rubber, is inserted between the lower surface of the anchor head and the covering tip portion, and the twisted grip 21 moves forward with the movement of the twisted PC steel wire 20 together with the lock plate 11 twisted forward. To prevent sending.

즉, PC강선(17)을 메다는구조물(16)등에 설치하였을 경우, 그 서스펜션구조물(16)이 바람등으로 흔들리게 되면 꼬인 PC강선에 인장력이나 압축력이 작용하여 단부가 다소 이동하기 때문에 상기 록플레이트(11)로 압착그립(21)의 선단을 누름과 동시에 피복(19)의 선단부가 앵커헤드(18)에 부딪히는 것을 방지하고 있다.That is, when the PC steel wire 17 is installed in the hanging structure 16 or the like, when the suspension structure 16 is shaken by the wind or the like, the tension or compression force acts on the twisted PC steel wire so that the end portion moves slightly. While pressing the tip of the crimping grip 21 with the plate 11, the tip of the sheath 19 is prevented from hitting the anchor head 18.

또한, PC강선(17)은 꼬인 PC강선에 한정되지 않으며, PC강봉이라도 좋다.The PC steel wire 17 is not limited to twisted PC steel wire, and may be a PC steel bar.

도 4는 다른 긴장재(25)를 나타낸 것이며, 접속부재(13)이 한장의 판(14)로 형성된 것 이외에는 상기 긴장재(15)와 동일한 구성이다.4 shows another tension member 25, which is the same configuration as the tension member 15 except that the connecting member 13 is formed of a single plate 14. As shown in FIG.

또한, 도 5의 긴장재(26)은 한끝에 두장의 판(6)으로 되는 접속부재(3)을 구비한 접속용 정착구(1)을 설치하고, 다른 끝에 한장의 판(14)로 되는 접속부재(13)을 구비한 접속용 정착구(12)를 설치한 것이다.In addition, the tension member 26 of FIG. 5 is provided with a connection fixing device 1 having a connecting member 3 having two plates 6 at one end thereof, and a connecting member having one plate 14 at the other end thereof. The connection fixing device 12 provided with (13) is provided.

이와 같이 사용하는 개소에 따라서 접속부재(3),(13)의 형태는 자유롭게 변경시킬 수가 있다.The shape of the connection member 3, 13 can be changed freely according to the location used in this way.

앵커헤드를 커플러의 결합구멍에 비틀려 박음으로서, 접속용 정착구를 긴장재의 단부에 용이하게 설치할 수 있게 된다.By twisting the anchor head into the coupling hole of the coupler, the connecting anchorage can be easily installed at the end of the tension member.

접속부재를 두장의 판으로 대략 자형으로 형성하므로서 핀 접합을 용이하게할 수가 있게 된다.The connecting member is roughly divided into two plates By forming in a shape of a child, pin joining can be facilitated.

또, 록플레이트가 긴장재의 단부를 누르는 작용을 한다.The lock plate also acts to press the end of the tension member.

그리고, 긴장재를 메다는 구조물에 사용할 때에 접합단부가 핀 접합할 수 있으므로 긴장재의 설치가 용이하다.In addition, when the tension member is used for the structure to be loaded, the joint ends can be pinned, so that the tension member can be easily installed.

또한, 록너트에 의하여 접속부재가 커플러에서 이동하지 않는다.In addition, the lock member does not move the connecting member from the coupler.

그리고, 긴장재의 이동으로 인한 파손을 방지한다.And it prevents the damage by the movement of a tension material.
