본 발명은 신축기능을 가지면서 시공이 간편하고 내구성이 우수하며 유지보수가 간단한 철도교량의 신축이음장치에 관한 것이다.The present invention relates to an expansion joint device of a railway bridge having a stretch function and easy construction, excellent durability and simple maintenance.

일반적으로 철도교량은 다수의 교각과 교각의 상부에 양단부가 안착 고정되는 다수의 상판들로 구성되며, 이들 상판과 상판의 연결부위는 온도변화에 따라 상판이 변형되는 신축량을 흡수하고, 기차의 이동에 따른 상판간의 간격의 변화량을 흡수할 수 있도록 상판이 서로 이격되어 있으며, 이 이격된 틈새에는 상판의 변위를 수용하면서 상판과 상판을 연결해 주는 신축이음장치가 설치된다.In general, a railway bridge is composed of a plurality of bridges and a plurality of tops on which both ends are seated and fixed at the top of the piers, and the connection between these tops and the tops absorbs the amount of expansion and contraction of the top plate as the temperature changes, and the movement of the train. The top plates are spaced apart from each other so as to absorb the amount of change in the gap between the top plates, and the spaced apart gap is provided with expansion joints for connecting the top plate and the top plate while receiving the displacement of the top plate.

이러한 신축이음장치는 양 상판에 대응되게 설치되는데 통상 그 형상은 이음부의 틈새를 최소화 하기 위해 통상 요철형상의 핑거를 지그재그형으로 돌출시켜 상판과 상판의 연결에 의한 틈새를 최소화 시켜 왔다.These expansion joints are installed to correspond to the upper plate, and its shape has generally minimized the gap by connecting the upper plate and the upper plate by zigzag protruding fingers in the shape of the irregularities in order to minimize the gap of the joint.

이러한 틈새이음장치의 조인트는 크게 개방형조인트와 폐쇄형조인트로 나뉠 수 있는데 개방형조인트는 조인트로 연결된 상판과 상판 사이가 비어 있는 구조로서 앵글보강형조인트 또는 핑거판조인트가 이에 속한다. 이러한 개방형조인트가 구성된 틈새이음장치는 시공이 편리하고 저렴한 장점이 있는 반면에 개방된조인트 내로 빗물등이 직접 흘러 들어가기 때문에 교량 구조물의 부식으로 내구성이 저하되는 단점이 있다.The joint of the gap joint device can be divided into an open joint and a closed joint. The open joint is an empty structure between the top plate and the top plate connected by the joint, and the angle reinforcement joint or the finger plate joint belongs to it. The gap joint device composed of such an open joint has a disadvantage in that the construction is convenient and inexpensive, while rainwater flows directly into the open joint, thereby deteriorating durability due to corrosion of the bridge structure.

폐쇄형조인트가 구성된 틈새이음장치는 상판과 상판사이에 빗물이 흘러들어가는것을 방지 하기 위하여 상판과 상판사이에 탄성체를 삽입하여 빗물의 유입을 차단하거나, 상판의 측단 일부를 절개하고 폐쇄형조인트를 설치한 후 다시 시멘트로 고착시킨 후에 하부에 빗물을 받아내는 홈통등을 설치하는 형식의 것이 있는데, 이러한 탄성체는 일정시간이 지나면 탄성력이 저하되어 빗물이 스며드는 단점이 있으며, 폐쇄형조인트 및 빗물받이 홈통의 설치 방법이 복잡하고 비용이 많이 들며 구조가 복잡한 단점이 있다.The gap joint device composed of closed joints prevents the inflow of rainwater by inserting an elastic body between the upper and upper plates to prevent rain water from flowing between the upper and upper plates, or cuts a part of the upper end of the upper plate and installs a closed joint. After fixing it with cement again, there is a type of gutter to receive rainwater at the bottom, and such an elastic body has a disadvantage in that rain water penetrates due to a decrease in elastic force after a predetermined time, and is a closed joint and rain gutter. The disadvantages are complex installation methods, high cost and complicated structure.

본 발명은 전술한 문제점을 해결하기 위해 발명된 것으로 철도교량의 상판의 이음부분에서 상판의 변위를 수용하면서도 자갈 또는 빗물등의 유입을 차단할 수 있고 또한 제작비용이 저렴한 철도교량의 신축이음장치를 제공하는데 그 목적이 있다.
The present invention has been invented to solve the above-described problems, while receiving the displacement of the top plate at the joint portion of the top plate of the railroad bridge can block the inflow of gravel or rainwater, etc., and also provides a low-cost railway bridge expansion joint device Its purpose is to.

The wedge 11 protruding downward is comprised, and the drip fitting groove 14 is comprised in the side by which the drip fitting hole 26 is clamped and fixed.

상기 충진재(27)는 방수성과 접착성을 구비한 것으로 그 분야에서 통상의 지식을 가진 자라면 다양한 제품을 필요에 따라 선택적으로 사용할 수 있는 것으로 이에 대한 자세한 설명은 생략한다. The filler 27 is provided with waterproof and adhesive properties, and those skilled in the art may selectively use various products as necessary, and thus detailed description thereof will be omitted.

도 2d에 서와 같이 양쪽 상판(30)에 고착된 앵글(10)의 측면에 형성된 물받 이끼움홈(14)에 물받이끼움구(26)를 억지끼워 물받이(25)를 설치한다. As shown in FIG. 2d, the drip tray 25 is installed in the drip fitting groove 14 formed on the side of the angle 10 fixed to both top plates 30 to install the drip holder 25.

상기 물받이(25)는 "V형으로 성형되고, 양끝단이 물받이끼움홈(14)에 억지끼워져 걸리도록 물받이끼움구(26)가 구성된 것으로, 고무재와 같은 탄성재질로 구성되며, 양 상판(30)에 고착된 앵글(10)의 길이만큼 절단하여 사용한다.The drip 25 is formed in a "V-shape, and the drip fitting hole 26 is configured so that both ends are sandwiched by the drip fitting groove 14, is composed of an elastic material such as rubber material, both top plate ( It is used by cutting the length of the angle 10 fixed to 30).

또한 상판(30)이 수축함에 따라 물받이끼움홈(14)에서 물받이끼움구(26)가 혹시라도 빠지는 것을 방지하기 위하여 추가적으로 앵글(10)의 길이만큼 절단한 물받이고정판(15)을 물받이끼움홈(14) 상부에 위치시키고, 고정볼트(16)로 고정할 수 있는데 이는 필요에 따라 선택적으로 사용이 가능하다.In addition, as the top plate 30 shrinks, the drip tray 26 is additionally cut by the length of the angle 10 in order to prevent the drip fitting hole 26 from falling out from the drip fitting groove 14 and the drip plate fitting groove 15 ( 14) It can be positioned at the top, and can be fixed by the fixing bolt 16, which can be selectively used as needed.

이후 도 2e 및 도 4에서와 같이 양 상판(30)에 고착된 앵글(10)을 덮어 우수의 유입을 차단하는 덥개(20)는 앵글(10)의 길이만큼 절단하여, 양 상판(30)에 고착된 앵글(10)의 돌기(12)가 돌기끼움훔(21) 및 돌기유동홈(22)에 끼워지도록 덮고, 양 앵글의 어느 한쪽에 볼트(17)를 볼트관통구멍(18)을 관통한 후 볼트체결구멍(13)에 체결하여 양앵글(10)의 한쪽에 덮개(20)를 고정시킨다. Then, as shown in FIGS. 2E and 4, the cover 20 covering the angle 10 fixed to both top plates 30 to block the inflow of rainwater is cut by the length of the angle 10 to both top plates 30. The projections 12 of the fixed angles 10 are covered so as to be fitted into the projection humps 21 and the projection flow grooves 22, and the bolts 17 are penetrated through the bolt through holes 18 at either of the angles. After fastening to the bolt fastening hole 13 to fix the cover 20 to one side of both angles (10).

상기 덮개(20)는 판형으로 성형된 것으로, 볼트(17)가 관통되어 고정되도록 앵글(10)의 볼트체결구멍(13)과 대응되게 볼트관통구멍(18)이 일정간격으로 다수 형성되고, 그 하부 일측에는 앵글(10)의 돌기(12)가 끼워지도록 돌기끼움구(21)가 구성되며, 타측에는 상판(30)의 변위에 의하여 끼워진 돌기(12)가 유동적으로 움직이도록 일정한 폭을 가진 돌기유동홈(22)이 구성된다. The cover 20 is formed in a plate shape, a plurality of bolt through holes 18 are formed at a predetermined interval to correspond to the bolt fastening hole 13 of the angle 10 so that the bolt 17 is penetrated and fixed, The projection fitting hole 21 is configured to fit the projection 12 of the angle 10 on one side of the lower side, and the projection having a constant width so that the projection 12 inserted by the displacement of the upper plate 30 is fluidly moved. Flow groove 22 is configured.

이후 도 2f에서와 같이 상판(30) 상부에 자갈(31)을 깔아 철도교량을 완성하는 것으로, 철도교량의 상판(30)에 충진재(27)로 앵글(10)이 고착되고, 상판(30)과 상판(30)사이는 덮개(20)가 덮여지므로 양 상판(30)사이의 이격된 틈으로 자갈(31) 또는 빗물등의 유입이 차단되며, 덮개(20)와 앵글(10)사이로 일부 유입 가능한 빗물등은 물받이(25)에서 받아져 교량구조물 양측 외부로 배출되게 된다. Then, as shown in FIG. 2F to finish the railway bridge by laying the gravel 31 on the upper plate 30, the angle 10 is fixed to the upper plate 30 of the railway bridge by the filler material 27, the upper plate 30 Since the cover 20 is covered between the and the upper plate 30, the inflow of the gravel 31 or rainwater is blocked by the spaced gap between both the upper plate 30, and partially introduced between the cover 20 and the angle 10. Possible rainwater is received from the drip tray 25 and is discharged to both sides of the bridge structure.

이러한 본 발명 신축이음장치(1)는 도 3a 내지 도 3b에서와 같이 상판(30)이 신축되더라도, 양 앵글(10)중 어느 한쪽에 고정된 덮개(20)와 양 앵글(10)에 끼워진 물받이는(25)는 덮개(20)의 돌기유동홈(22)에 끼워진 상판(30)에 고착된 앵글(10)의 돌기(12)가 돌기유동홈(22) 내에서 유동적으로 움직이고, 탄성재질의 물받이(25)가 펼쳐지거나 접히면서 상판(30)의 변위를 수용하게 되어 상판(30)이 변위 되더라도 자갈(31) 또는 빗물등의 유입을 차단하게 된다. In the present invention, the expansion joint 1 includes a cover 20 fixed to either one of both angles 10 and a drip tray fitted to both angles 10, even when the upper plate 30 is stretched as shown in FIGS. 3A to 3B. Silver 25 is a projection 12 of the angle 10 is fixed to the upper plate 30 fitted in the projection flow groove 22 of the cover 20, the fluid flow in the projection flow groove 22, the elastic material As the drip tray 25 is expanded or folded to accommodate the displacement of the upper plate 30, even if the upper plate 30 is displaced, it blocks the inflow of gravel 31 or rainwater.

이상에서와 같이 본 발명 신축이음장치(1)의 주요구성인 앵글(10), 덮개(20) 및 물받이(25)는 성형하여 제작이 가능하므로 제작비용이 크게 절감되고, 제작이 용이한 장점이 있으며,As described above, the angle 10, the cover 20, and the drip 25, which are the main components of the expansion joint device 1 of the present invention, may be manufactured by molding, thereby greatly reducing the manufacturing cost and making the manufacturing easy. And

시공시 상판(30)의 폭만큼 앵글(10), 덮개(20) 및 물받이(25)를 절단하여 시공하므로서 시공이 매우 간단하고, 시공비용이 절약되며, 상판(30)의 신축에 관계없이 자갈(31) 또는 빗물등의 유입을 차단하여 교량구조물의 내구성을 향상시켜 철도교량의 수명을 연장시키는 등의 효과가 있다.
