본 발명의 콘크리트 침목도 철도차량의 하중이 레일에 가해지면 이 하중을 콘크리트도상에 전달하여 하중이 넓게 분포되면서 노반에 전달되게 하는 맥락은 종래와 같다.Concrete sleeper of the present invention, when a load of a railroad car is applied to the rail, the load is transmitted to the concrete diagram, the load is widely distributed, and the context to be transmitted to the roadbed is the same as before.

다만 본 발명은 콘크리트 침목을 더욱 효과적으로 사용할 수 있도록 한 것으로 이는 도3과 도4에서와 같이 크게 가압판(300)과, 이 가압판(300)에 삽입되어 콘크리트 침목(100)에 강성과 내구성을 부여하는 PC강봉(400)과, PC강봉의 휘어짐을 방지하는 휘어짐방지링(200)이 기본적으로 동원된다.However, the present invention allows the use of concrete sleepers more effectively, which is inserted into the pressure plate 300 and the pressure plate 300 as shown in FIGS. 3 and 4 to give rigidity and durability to the concrete sleepers 100. PC steel bar 400, and the bending prevention ring 200 to prevent the bending of the PC steel bar is basically mobilized.

가압판(300)은 콘크리트 침목(100) 양단부 내측에 각기 독립적으로 위치하는데 상하단에는 각각의 PC강봉(400)이 삽입될 수 있는 삽입구멍(310)이 형성된다.The pressing plate 300 is positioned independently of both ends of the concrete sleeper 100, the upper and lower ends are formed with an insertion hole 310 into which the respective PC steel bar 400 can be inserted.

PC강봉(400)은 가압판(300)의 삽입구멍(310)을 통하여 수평으로 삽입되고 한쪽에는 머리부(420)가 형성되며 다른 한쪽에는 나사부(410)가 일체로 형성된 상태에서 나사부(410)가 체결부재(500)와 나사 결합되면 수축되면서 가압판(300)을 안쪽으로 가압하는 역활을 수행한다.PC steel bar 400 is inserted horizontally through the insertion hole 310 of the pressure plate 300, the head portion 420 is formed on one side and the screw portion 410 is formed in a state where the threaded portion 410 is integrally formed on the other side. When the screw is coupled to the fastening member 500 and performs a role of pressing the pressing plate 300 inward while contracting.

휘어짐방지링(200)은 PC강봉(400)이 각 가압판(300)에 삽입 고정되면 이 PC강봉(400)들의 외주면을 일체로 감싸 PC강봉이 바깥쪽으로 휘어지는 것을 방지하도록 구성된다.The bending prevention ring 200 is configured to prevent the PC steel bar from bending outward when the PC steel bars 400 are fixedly inserted into each pressing plate 300 to integrally surround the outer circumferential surfaces of the PC steel bars 400.

여기서 휘어짐방지링(200)은 PC강봉(400)들의 외주면에 일정한 간격을 가지고 다수 설치 사용되는데, 도면 도3과 도4에서와 같이 개수가 한정 되는 것은 아니고 PC강봉의 휘어짐을 방지할 수 있다면 상황에 따라 많게 형성하거나 적게 형성할 수 있음을 밝혀둔다.Here, the bending prevention ring 200 is used to install a plurality of predetermined intervals on the outer circumferential surface of the PC steel bar 400, the number is not limited as shown in Figures 3 and 4, if the situation can prevent the bending of the PC steel bar Note that it can be formed more or less depending on.

이와 같이 구성된 본 발명을 사용하기 위해서는 먼저 가압판(300)의 상하단에 형성된 삽입구멍(310)에 각 PC강봉(400)을 수평으로 삽입하면 가압판(300)은 PC강봉(400)의 머리부(420)와 나사부(410)측에 위치하게 된다.In order to use the present invention configured as described above, if each PC steel bar 400 is horizontally inserted into the insertion hole 310 formed in the upper and lower ends of the pressure plate 300, the pressure plate 300 is the head 420 of the PC steel bar 400. ) And the threaded portion 410 side.

상기와 같이 가압판(300)이 PC강봉(400)과 연결되면 이를 형틀에 적절하게배치한 후 이 PC강봉들의 외주면에 휘어짐방지링(200)을 일정한 간격으로 설치하고 콘크리트를 형틀에 타설 양생시킨다.As described above, when the pressure plate 300 is connected to the PC steel bar 400, it is appropriately placed in the mold, and then installs the bend prevention ring 200 on the outer circumferential surface of the PC steel bars at regular intervals and pours concrete into the mold.

이후 콘크리트가 양생되면 별도의 인장수단을 이용하여 PC강봉(400)의 나사부(410)측을 잡고 인장시키면 머리부(420)에 의해 PC강봉(400)이 외부로 이탈되지 않으면서 인장된다. 이때 PC강봉이 인장된 상태에서 체결부재(500)를 나사부(410)와 나사 결합하면 PC강봉(400)은 수축되면서 가압판(300)을 안쪽으로 가압하기 때문에 전체적인 콘크리트 침목(100)의 강성과 내구성이 증대된다.Then, when the concrete is cured, the tension is applied to the PC steel bar 400 by the head 420 by pulling the threaded portion 410 of the PC steel bar 400 by using a separate tensioning means. At this time, if the fastening member 500 is screwed with the screw 410 in the tensioned state of the PC steel bar, the PC steel bar 400 is contracted while pressing the pressure plate 300 inward, so the rigidity and durability of the overall concrete sleeper 100 Is increased.

상기와 같은 상태에서 장기간 콘크리트 침목(100)을 사용시 PC강봉(400)이 바깥쪽으로 휘어질려고 하더라도 휘어짐방지링(200)이 일정한 간격을 가지고 설치되어 있어 바깥쪽으로 휘어지지 않게 된다.When using the concrete sleeper 100 in the state as described above, even if the PC steel bar 400 is to be bent to the outside, the bending prevention ring 200 is installed at regular intervals so that it does not bend outward.

이상에서 살펴본 바와 같이 본 발명에 의하면, 콘크리트 침목 내부에 PC강봉이 가압판과 함께 매설되어 있고, 이 PC강봉측에는 별도의 휘어짐방지링이 설치되어 있기 때문에 종래 콘크리트 침목 보다 전체적인 콘크리트 침목의 강성 및 내구성이 증대되는 것임은 물론 이에 따라 반영구적으로 제품을 사용할 수 있고 생산원가는 크게 절감되는 효과가 있는 것이다.As described above, according to the present invention, since the PC steel bar is embedded with the pressure plate inside the concrete sleeper, and the PC steel bar side is provided with a separate anti-bending ring, the rigidity and durability of the overall concrete sleeper is better than the conventional concrete sleeper. As a result, the product can be used semi-permanently and the production cost is greatly reduced.

이상에서는 본 발명을 특정의 바람직한 실시예를 참고하여 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 요지를 벗어나지 않는 범위에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 이루어질 수 있는 것임을 밝혀둔다.The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above embodiments and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention.
