본 발명은 교량의 신축이음장치에 관한 것으로써, 특히 배수로를 형성하는 부재의 내구성을 향상시키고 충격/진동으로부터 구조체를 구조적으로 안정화시키며 균열/파손부위에도 안정된 시공을 가능하게 한 교량의 신축이음장치에 관한 것이다. The present invention relates to an expansion joint device for a bridge, in particular, an expansion joint device for a bridge which improves durability of a member forming a drainage path, structurally stabilizes a structure from impact / vibration, and enables stable construction even at a crack / damage site. It is about.

일반적으로 교량은 온도변화에 따른 수축 및 팽창, 강풍 또는 지진등의 자연환경변화에 의해서 안전하도록 복수의 상판슬래브들을 일정정간격으로 이격시키면서 연결하여 시공되는 구조를 가진다.In general, a bridge is constructed by connecting a plurality of top slabs spaced at regular intervals so as to be safe from natural environment such as contraction and expansion, strong wind or earthquake due to temperature change.

또한, 일정간격 이격된 틈새에 이물질의 진입방지 및 우천시 우수(雨水)의 낙하방지를 위하여 이격된 틈새에는 신축이음장치가 채용된다.In addition, expansion joints are employed in the gaps spaced apart to prevent the entry of foreign matter in the gaps spaced at regular intervals and to prevent the fall of rainwater during rain.

이러한 교량의 신축이음장치는 교량의 슬래브와 슬래브 사이 또는 슬래브와 교대 사이에 설치되어서, 슬래브 사이를 상호 연결하면서 외부 온도변화에 따른 슬래브의 신장 또는 수축변형을 흡수하여 교량의 구조를 안전하게 유지시켜 준다.The expansion joint of the bridge is installed between the slab and the slab of the bridge or between the slab and the alternating, it is connected between the slab while absorbing the elongation or contraction deformation of the slab according to the external temperature change to maintain the structure of the bridge safely .

특히, 철도가 통행하는 교량에는 소음과 하중에 의한 대응력을 가질 수 있도록 지면에 설치되는 선로와 같이 많은 양의 자갈이 깔리게 되고, 그에 따라 교량과 교량사이에 설치되는 슬래브 사이의 이음부분에는 자갈이 진입되어 슬래브의 신축작용을 방해하게 된다.In particular, a large amount of gravel is laid on the bridge that the railway passes, such as a track that is installed on the ground so that it can respond to noise and load, and accordingly, the joint between the bridge and the slab installed between the bridge is gravel. This enters and interferes with the stretching of the slab.

이를 위해서 철도 교량에 설치되는 신축이음장치는 차량의 통행시 충격과 진동에 의해 상호 마찰/충돌되면서 파쇄된 자갈들이 슬래브 사이의 이음부분에 투입되지 않도록 설계되어진다.To this end, expansion joints installed on railway bridges are designed so that crushed gravel does not enter the joints between the slabs as they are rubbed and collided with each other by shocks and vibrations when the vehicle passes.

상기와 같은 철도 교량용 종래 신축이음장치(100)가 도 1에 도시되어 있다. 이는 교량사이에 설치되는 슬래브(A)(B) 사이의 이음부분에 덮혀지도록 탄성변형이 가능한 고무재질의 차단시트(110)가 마련되어 있고, 슬래브(B)에는 차단시트(110)의 일단과 함께 스크류에 의해 지지플레이트(120)가 고정되어 있으며, 슬래브(A)에는 차단시트(110)의 타단과 함께 지지플레이트(120)의 상부가 덮혀지도록 덮개플레이트(130)가 고정되어서 슬래브(A)(B)사이의 이음부분으로 자갈등이 투입되는 것을 방지하도록 되어 있다.The conventional expansion joint device 100 for a railway bridge as described above is shown in FIG. It is provided with a rubber blocking sheet 110 that is elastically deformable so as to be covered in the joint between the slab (A) (B) is installed between the bridge, the slab (B) with one end of the blocking sheet (110). The support plate 120 is fixed by a screw, the cover plate 130 is fixed to the slab (A) so that the upper end of the support plate 120 with the other end of the blocking sheet 110 is fixed to the slab (A) ( B) The gravel part is prevented from entering into the joint part between.

또한, 지지플레이트(120)와 덮개플레이트(130) 사이에는 자갈로부터 파손된 파쇄물들이 유입되는 것을 방지할 수 있도록 고무판(140)이 지지플레이트(120)에 고정되어 있다.In addition, the rubber plate 140 is fixed to the support plate 120 between the support plate 120 and the cover plate 130 to prevent the broken pieces from being broken from being introduced.

이와 같은 신축이음장치는 자갈 또는 파쇄된 자갈들이 슬래브 사이의 이음부로 유입되는 것을 방지하고, 차단시트(110)에 의해서 빗물등의 낙하를 방지하면서, 슬래브(A)(B) 사이의 이음부 간격변화를 흡수할 수 있도록 한다.Such expansion joint device prevents the gravel or crushed gravel from flowing into the joint between the slabs, and prevents falling of rainwater by the blocking sheet 110, while the gap between the joints between the slab (A) (B). Make it possible to absorb changes.

그러나 상기와 같은 신축이음장치는 다음과 같은 문제점을 가진다.However, the expansion joint as described above has the following problems.

첫째, 이음부와 접하는 각 슬래브(A)(B)의 가장자리부분들에 균열이 발생되어 신축이음장치의 보수시공이 이루어지는 경우, 균열진 슬래브(A)(B)에 차단시트(110)가 불규칙하게 접촉되므로 틈새가 발생되어 누수(漏水)가 발생되고 이로 인하여 슬래브(A)(B)의 수명이 단축되는 문제점이 있다.First, when the cracks are generated at the edges of each slab (A) (B) in contact with the joint portion, and the expansion and contraction of the expansion joint is performed, the blocking sheet 110 is irregular in the cracked slab (A) (B). Since there is a gap is generated so that the water (漏水) is generated, there is a problem that the life of the slab (A) (B) is shortened.

따라서 이러한 구조의 이음장치는 균열이 발생된 슬래브에 적용하기에는 부적합하다.Therefore, the joints of this structure are not suitable for application to cracked slabs.

둘째, 차단시트(110)가 고무재로 이루어짐으로써 장기간 적용시 온도변화에 따라 경화되는 등 내구성이 떨어지는 문제점이 있다.Second, since the blocking sheet 110 is made of a rubber material, there is a problem that the durability is poor, such as hardening according to the temperature change during long-term application.

Spaced apart to form the expansion space (30).

본 발명 실시예의 신축이음장치는 신축공간(30)에 이물질의 진입을 방지하고 배수를 가능하도록 신축공간(30) 부분에 설치된다.The expansion joint device of the embodiment of the present invention is installed in the expansion space 30 to prevent entry of foreign matter into the expansion space 30 and to enable drainage.

상기 신축이음장치는 신축공간(30)을 덮도록 마련되고 상기 신축공간(30)측으로 하향굴곡되어 배수로(41)를 형성하며 양단부가 각각 상기 제1,2구조체(10)(20)에 고정되며 금속으로 형성된 금속시트(40)와, 상기 금속시트(40)의 양측 가장자리 상하면을 감싸며 상기 제1,2구조체(10)(20)의 상면에 밀착되는 제1,2고무판(61)(62)과, 상기 제1구조체(10)에 상기 제1고무판(61)과 함께 상기 금속시트(40)의 일단을 고정시키는 제1고정부재(71)와, 상기 금속시트(40)의 상부에 마련되며 일단이 상기 제2고무판(62) 및 상기 금속시트(40)의 타단과 함께 상기 제2구조체(20)에 제2고정부재(72)에 의해서 고정되며 타단이 자유단으로 되는 이동덮개판(50)을 구비한다.The expansion joint device is provided to cover the expansion space 30 and is bent downward toward the expansion space 30 to form a drainage passage 41, and both ends are fixed to the first and second structures 10 and 20, respectively. First and second rubber plates 61 and 62 which surround a metal sheet 40 formed of metal and upper and lower surfaces of both edges of the metal sheet 40 and closely contact the upper surfaces of the first and second structures 10 and 20. And a first fixing member 71 fixing one end of the metal sheet 40 together with the first rubber plate 61 to the first structure 10, and provided on an upper portion of the metal sheet 40. A movable cover plate 50 having one end fixed to the second structure 20 by the second fixing member 72 together with the other ends of the second rubber plate 62 and the metal sheet 40 and the other end of which is the free end. ).

또한, 상기 금속시트(40)의 양단부와 상기 제1,2구조체(10)(20) 사이의 틈새에 방수재(81)(82)가 충진되어 있다.In addition, waterproof materials 81 and 82 are filled in the gaps between both ends of the metal sheet 40 and the first and second structures 10 and 20.

이와 같은 신축이음장치는 제1,2구조체(10)(20)가 온도변화에 따라 도 2b에 도시된 바와 같이 신축될때 금속시트(40)가 탄성변형되고 이동덮개판(50)이 제1,2 구조체(10)(20)의 신축변위만큼 이동되게 된다. 이때 이동덮개판(50)은 일단부가 자유단으로 구성됨으로써 제1,2구조체(10)(20)가 신축되더라도 변형되지 아니한다.This expansion joint device is the first and the second structure 10, 20 is stretched as shown in Figure 2b according to the temperature change when the metal sheet 40 is elastically deformed and the movable cover plate 50 is the first, 2 is moved by the expansion and contraction of the structure (10) (20).
