철도 교량 방음벽 전도방지장치{APPARATUS FOR PREVENTING FALLDOWN OF SOUNDPROOFED WALL}Railway bridge soundproof wall fall prevention device {APPARATUS FOR PREVENTING FALLDOWN OF SOUNDPROOFED WALL}

본 발명은 철도 교량 방음벽 전도방지장치에 관한 것으로, 더욱 상세하게는 철도 레일을 따라 시공되는 방음벽을 자체 강도가 큰 방음틀 및 흡음재로 분리 구성하고 횡풍이 방음틀의 곡면을 타고 흘러 나가도록 함과 아울러 일렬로 배열되는 다수의 방음틀을 서로 결속 및 철도 교량에 견고하게 고정하여 방음벽이 전도되지 않도록 한 철도 교량 방음벽 전도방지장치에 관한 것이다.The present invention relates to a railway bridge soundproof wall fall prevention device, and more specifically, to separate the soundproof wall constructed along the railroad rail with a high-strength soundproof frame and sound-absorbing material and to let the transverse wind flow out of the curved surface of the soundproof frame. In addition, the present invention relates to a railway bridge soundproof wall fall prevention apparatus, in which a plurality of soundproofed frames arranged in a row are firmly fixed to each other and the railway bridge so that the soundproof walls are not conducted.

일반적으로 교량은 다리를 말하는 것으로, 용도에 따라 철도가 놓여지는 철로교와 차량의 통행을 위한 차도 그리고 사람의 보행을 위한 육교 등 기능과 목적에 따라 다수 제안되고 있다.In general, a bridge refers to a bridge, and a number of proposals are made according to functions and purposes, such as a railway bridge on which a railroad is placed, a roadway for traffic, and an overpass for human walking.

이와 같은 여러 종류의 교량 중 기차가 통과되는 철도가 목적인 철로교는 일반적인 지반 위에 건설하는 도로와는 달리 교각과 기초로 이루어지는 다수의 하부 구조와, 그 하부 구조의 상측에 놓여지는 바닥 틀 그리고 주 트러스로 구분되는 상 부구조로 대별된다.Among these bridges, the railway bridge, which is intended for railways through which trains pass, has a number of substructures consisting of piers and foundations, floor frames placed on top of the substructures, and main trusses, unlike roads built on general ground. It is roughly divided into upper structures divided by.

한편, 철로 교를 시공할 때에는 먼저 가교지점의 지형ㅇ지질ㅇ기상ㅇ지진 등의 자연 조건과 교통상황ㅇ경제효과ㅇ용지확보ㅇ환경 등의 사회적 조건에 대한 자료수집이나 각종 조사를 실시한 후 다리의 형식ㅇ사용재료ㅇ하부구조ㅇ기초공법ㅇ가설방법 등의 기술검토와 공사비 산출, 환경 사정을 고려하여 세부 설계와 가설법을 검토한 후 공사를 개시한다.On the other hand, when constructing a railway bridge, first collect data or conduct various surveys on the natural conditions such as topography, geological and earthquake of the bridge site, and social conditions such as traffic conditions, economic effects, land security, and environment. After reviewing the detailed design and construction method in consideration of technical review, calculation of construction cost, and environmental conditions such as form materials, substructure, foundation method and construction method, construction starts.

한편, 철로 교에서는 구조상 매우 큰 주행 소음이 발생되며, 철로 교가 근접되어 있는 주택가에는 철로 교를 통과하는 열차 소음이 그대로 전달되어 많은 민원이 제기되고 있다.On the other hand, in railway bridges, a very large running noise is generated due to its structure, and a lot of complaints have been raised because the noise of trains passing through the railway bridges is transmitted as it is to a residential area near the railway bridge.

이러한 민원을 해소하기 위하여 철로교에 방음시설을 구축하고 있다.In order to resolve these complaints, soundproof facilities are being built in railway bridges.

종래 방음시설은 흡읍공을 갖는 흡음재 또는 소리가 밖으로 나가지 않도록 차단하는 차단벽을 들 수 있다. 종래 방음시설은 열차의 주행 소음을 줄이기 위하여 대개 지면으로부터 열차 높이 이상으로 시공되고 있는데 열차의 주행 소음을 줄이는 것만을 목적으로 하기 때문에 교량과의 결속력이 미약하여 횡풍이 불어올 경우 횡풍에 의해 전도되는 문제점이 있다.Conventional soundproofing facilities may include a sound absorbing material having a suction hole or a blocking wall to prevent the sound from going out. Conventionally, soundproofing facilities are usually constructed above the height of the train from the ground to reduce the running noise of the train.The purpose of this is to reduce the running noise of the train. There is a problem.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 열차의 주행 소음이 방음벽에 의해 외부로 전달되지 않도록 함은 물론 횡풍이 방음벽을 타고 외부로 흘 러나가도록 하고 일렬로 연결되는 방음벽간의 결속력을 강화하고 방음벽이 철도 교량을 지지기반으로 하여 세워진 상태를 유지할 수 있도록 함으로써 횡풍이 불어오더라도 전도되지 않도록 한 철도 교량 방음벽 전도 방지 장치를 제공하는데 그 목적이 있다.The present invention is to solve the above problems, to prevent the running noise of the train to be transmitted to the outside by the soundproof wall, as well as cross wind flows to the outside riding the soundproof wall and strengthen the binding force between the soundproof wall connected in line The purpose of the present invention is to provide a railroad bridge soundproof wall fall prevention apparatus that is prevented from falling even when a wind blows by allowing the soundproof wall to be built on the railroad bridge as a support base.

전술한 바와 같은 목적을 달성하기 위한 본 발명에 의한 철도 교량 방음벽 전도 방지 장치는, 교각 상부에 구축되는 철도 슬래브층과; 상기 철도 슬래브층의 폭방향 양측에 각각 세워지는 방음벽과; 경사형 지지부, 상기 지지부의 상하단부에 각각 형성되어 상기 방음벽과 상기 철도 슬래브층에 각각 체결구로 고정되는 고정부로 이루어져 상기 고정부를 통해 상기 철도 슬래브층를 지지기반으로 하여 상기 방음벽을 지지하는 지지수단을 포함하여 구성된 것을 특징으로 한다.Railroad bridge soundproof wall fall prevention apparatus according to the present invention for achieving the object as described above, the railroad slab layer is formed on the top of the bridge; Soundproof walls erected on both sides in the width direction of the railway slab layer; Support means for supporting the sound barrier by the inclined support portion, the upper and lower end portions of the support portion are respectively fixed to the soundproof wall and the railroad slab layer fixed by fasteners on the railroad slab layer as a support base. Characterized in that configured to include.

본 발명에 의한 철도 교량 방음벽 전도 방지 장치에 의하면, 방음벽의 외면이 곡선형으로 형성되어 바람이 방음벽에 부딪치지 않고 방음벽을 타고 외부로 흘러 나가고, 또한, 일렬로 배열되는 방음틀이 서로 결속되어 방음벽이 전체적으로 인장력을 발휘함과 아울러 철도 교량에 대한 버팀력이 강화되어 방음벽이 전도되지 않으므로 방음벽의 전도에 따른 안전사고를 미연에 방지할 수 있고 유지보수를 위한 비용을 절감할 수 있다.According to the railway bridge soundproof wall fall prevention apparatus according to the present invention, the outer surface of the soundproof wall is formed in a curved shape so that the wind does not hit the soundproof wall and flows through the soundproof wall to the outside, and the soundproof frames arranged in a row are bound to each other to form a soundproof wall. As a result of showing the tensile force as a whole, the strengthening force on the railway bridge is reinforced so that the soundproof walls are not inverted, thereby preventing safety accidents caused by the fall of the soundproof walls and reducing the cost for maintenance.

도 1 내지 도 3에서 보이는 것처럼, 본 발명에 의한 철도 교량 방음벽 전도 방지 장치는, 교각(1) 상단에 형성되는 기초슬래브층(2)과; 기초슬래브층(2) 위에 형성되며 철도 레일(3)이 깔리는 철도 슬래브층(10)과; 철도 슬래브층(10)의 폭방향 양측에 각각 세워지는 방음벽(20)과; 방음벽(20)을 지지하는 지지수단(30)을 포함하여 구성된다.1 to 3, the railway bridge soundproof wall fall prevention apparatus according to the present invention, the base slab layer (2) formed on the upper end of the bridge (1); A railway slab layer 10 formed on the foundation slab layer 2 and on which the railway rails 3 are laid; Soundproof walls 20 which are respectively erected on both sides in the width direction of the railway slab layer 10; It comprises a support means 30 for supporting the soundproof wall (20).

철도 슬래브층(10)은 바닥부(11) 및 바닥부(11)의 폭방향 좌우 양측에 각각 상부로 돌출되는 제1,2난간부(12)로 이루어진다. 여기에 방음벽(20)이 끼워질 수 있도록 제1,2난간부(12)에는 상부를 향해 개방된 체결홈(13)이 형성된다.The railroad slab layer 10 includes a bottom portion 11 and first and second handrail portions 12 protruding upward on both left and right sides of the bottom portion 11 in the width direction. The fastening groove 13 opened toward the upper portion is formed in the first and second handrails 12 so that the soundproof wall 20 can be fitted thereto.

방음벽(20)은 내부에 중공부가 형성되며 마주하는 면에 다수의 흡음공(21a)이 구비된 박스형 방음틀(21), 방음틀(21)의 저부에 형성되어 철도 슬래브층(10)의 제1,2난간부(12)의 체결홈(13)에 끼워지는 체결돌기(22), 방음틀(21)의 저부에 연장 형성되어 철도 슬래브층(10)에 매설된 앵커(14)에 고정되는 플랜지(23) 및 다수의 흡음공(24a)을 갖으며 방음틀(21) 내부에 삽입되는 흡음재(24)를 포함하여 구성된다.The soundproof wall 20 is formed in the bottom of the box-type soundproof frame 21 and the soundproof frame 21 provided with a plurality of sound absorbing holes 21a on opposite sides thereof, and a hollow portion is formed therein, thereby forming the rail slab layer 10. The fastening protrusion 22 fitted into the fastening groove 13 of the first and second handrails 12 and the bottom of the sound insulation frame 21 are extended to be fixed to the anchor 14 embedded in the railway slab layer 10. It comprises a sound absorbing material 24 having a flange 23 and a plurality of sound absorbing holes 24a and inserted into the sound insulation frame 21.

이와 같은 구성의 방음벽(20)은 철도 슬래브층(10)의 제1,2난간부(12)에 각각 세워져 열차 주행시 발생되는 소음을 흡음하여 감쇄한다.The soundproof wall 20 having such a configuration stands on the first and second handrails 12 of the railway slab layer 10, respectively, and absorbs and attenuates the noise generated when the train runs.

방음벽(20)은 다수개가 제1,2난간부(12)를 따라 일렬로 배열되면서 시공될 수 있으며, 이때, 연속되는 방음벽(20)은 횡풍에 대한 전도방지를 위하여 체결돌기(22)와 앵커(14)를 통해 철도 슬래브층(10)에 설치되긴 하지만, 상호 간의 결속 을 통한 지지기반을 확보하기 위하여 방음틀(21)의 길이방향 일측에 결속돌기(25)가 형성된다.The soundproof wall 20 may be constructed while a plurality of the first and second railings 12 are arranged in a line, and in this case, the continuous soundproof wall 20 is a fastening protrusion 22 and an anchor to prevent conduction against transverse wind. Although installed on the rail slab layer (10) through (14), in order to secure a support base through the binding between each other, the binding projection 25 is formed on one side of the soundproof frame (21) in the longitudinal direction.

즉, 방음틀(21)은 내부에 공간이 형성된 구조이기 때문에 결속돌기(25)를 방음틀(21) 내부 공간에 맞는 크기로 제작하여 연속되는 다른 방음틀(21) 내부에 결속돌기(25)를 끼우고 이 부분에 체결구(26)를 체결함으로써 연속되는 방음벽(20)을 서로 결속할 수 있다. That is, since the sound insulation frame 21 has a space formed therein, the binding projection 25 is manufactured to have a size suitable for the internal space of the sound insulation frame 21, and the binding protrusion 25 is formed inside another sound insulation frame 21 which is continuous. By inserting and fastening the fastener 26 in this portion it is possible to bind the continuous soundproof wall 20 to each other.

방음틀(21)은 횡풍이 방음틀(21)의 표면을 따라 방음틀(21)의 바깥쪽으로 흘러 나가도록 반달형으로 형성된다.The sound insulation frame 21 is formed in a half moon shape so that the horizontal wind flows outward of the sound insulation frame 21 along the surface of the sound insulation frame 21.

지지수단(30)은 경사형 지지부(31), 지지부(31)의 상하단부에 각각 형성되어 방음벽(20)과 철도 슬래브층(10)에 각각 체결구(33)로 고정되는 고정부(32)로 이루어진다. 지지수단(30)은 고정부(32)를 통해 철도 슬래브층(10)를 지지기반으로 하여 방음벽(20)을 지지한다.The support means 30 is formed on the inclined support part 31 and the upper and lower ends of the support part 31, respectively, and is fixed to the soundproof wall 20 and the railroad slab layer 10 fixed with fasteners 33, respectively. Is made of. The support means 30 supports the soundproof wall 20 on the basis of the rail slab layer 10 through the fixing part 32.

이와 같이 구성된 본 발명에 의한 철도 교량 방음벽 전도방지장치의 작용은 다음과 같다.The operation of the railway bridge soundproof wall fall prevention apparatus according to the present invention configured as described above is as follows.

방음벽(20)은 외주면이 반달형이기 때문에 횡풍이 불어올 경우 방음틀(21)의 곡률을 타고 방음틀(21) 외부로 흘러 나가게 되어 약한 바람에 대해서는 흔들림없이 세워진 상태를 유지한다.Since the outer circumferential surface is a half moon type, the soundproof wall 20 flows out to the outside of the soundproof frame 21 by the curvature of the soundproof frame 21 to maintain a standing state against the weak wind.

한편, 방음벽(20)은 방음틀(21)의 바닥면이 제1,2난간(12)의 상면에 면접촉된 상태에서 앵커(14)에 고정되며, 아울러 체결돌기(22)가 제1,2난간(12) 내부에 삽입되어 있고, 아울러 지지수단(40)이 철도 슬래브층(10)을 지지기반으로 하여 방 음벽(20)을 밀어 지지함으로써 바람의 세기가 큰 횡풍이 불어오더라도 방음벽(20)이 철도 슬래브층(10)을 지지기반으로 하여 버팀력을 발휘함에 따라 전도되지 않는다.Meanwhile, the soundproof wall 20 is fixed to the anchor 14 while the bottom surface of the soundproof frame 21 is in surface contact with the top surfaces of the first and second handrails 12, and the fastening protrusions 22 are formed of the first, second and second handrails. 2 is inserted into the handrail 12, and the support means 40 supports the soundproof wall 20 by pushing the soundproof wall 20 on the basis of the railroad slab layer 10, even if a wind blows with a high wind strength. 20) the railway slab layer (10) as a support base to exert a force as it does not fall.

이와 함께 일렬로 연속되는 방음벽(20)들이 결속돌기(25)를 통해 서로 결속되어 일부 구간의 방음벽(20)이 흔들리려 하더라도 근접되는 방음벽(20)끼리 서로 인장함으로써 방음벽(20)의 전도가 일어나지 않는다.In addition, even if the soundproof walls 20 continuous in a row are bound to each other through the binding protrusions 25 and the soundproof walls 20 in some sections are to be shaken, the soundproof walls 20 are adjacent to each other so that the conduction of the soundproof walls 20 occurs. Do not.

한편, 바람이 방음벽(20)의 외벽을 타고 흘러 나가도록 함으로써 방음벽(200의 전도를 막을 수 있지만, 바람이 강하게 되면 바람의 방향을 유도하는 것만으로는 방음벽(20)에 가해지는 큰 충격을 막을 수 없으며, 이를 해결하기 위하여 일부 바람이 방음벽(20)을 통과하도록 구성될 수 있다. 즉, 도 4에서와 같이, 방음벽(20)의 내부에는 도 4 기준 좌우로 연통 가능하게 통공(27)이 형성된다. 바람은 통공(27)을 통해 빠져나가게 되어 방음벽(20)은 바람에 의한 충격이 전가되지 않는다. 통공(27)은 바람이 상부를 향하도록 상향 경사지게 형성된다. 여기서, 통공(27)을 통해 열차의 주행 소음이 외부로 나갈 수 있으므로 통공(27)을 개폐하는 베인(28)이 적용된다. 베인(28)은 방음벽(20)의 내측면에 배치되어 상단부가 힌지(28a) 결합되고, 탄성부재(미도시)를 통해 상시 통공(27)을 폐쇄하는 방향으로 탄력 지지된다. 따라서, 바람이 약하면 상기 탄성부재에 의해 통공(27)이 폐쇄 상태를 유지하며, 바람이 강하면 베인(28)이 바람에 의해 밀려 통공(27)이 개방되는 것이다.On the other hand, it is possible to prevent the conduction of the soundproof wall 200 by allowing the wind to flow out of the outer wall of the soundproof wall 20. However, when the wind is strong, the large shock applied to the soundproof wall 20 is prevented only by inducing the direction of the wind. In order to solve this problem, some wind may be configured to pass through the soundproof wall 20. That is, as shown in Fig. 4, the inside of the soundproof wall 20 allows the communication hole 27 to communicate left and right with reference to Fig. 4. The wind is drawn out through the through hole 27 so that the sound-proof wall 20 is not imparted by the wind, and the through hole 27 is formed to be inclined upward so that the wind is directed upward. Since the running noise of the train can go out through the vane 28 is applied to open and close the through hole 27. The vane 28 is disposed on the inner side of the soundproof wall 20, the upper end is coupled to the hinge (28a) Through the elastic member (not shown) The elastic member is elastically supported in the direction of closing 27. Therefore, when the wind is weak, the through hole 27 is kept closed by the elastic member, and when the wind is strong, the vane 28 is pushed by the wind and the through hole 27 is closed. To be open.
