Description
본 고안은 슬라브 궤도 시스템에 관한 것으로서, 특히 철도 레일을 부설하기 위해 선로에 시공되는 슬라브 궤도와 이 슬라브 궤도에 삽입되는 돌기체를 포함한 철로용 슬라브 궤도 시스템의 구조에 관한 것이다.The present invention relates to a slab track system, and more particularly, to a structure of a track slab track system including a slab track installed on a track for laying railroad rails and a protrusion inserted into the slab track.
철도선로중에 슬라브 궤도로 시공되는 부분에 있어서, 종래의 슬라브 궤도시스템은 도 6a 및 도 6b에 도시된 것과 같이 선로의 토목노반(B)에 설치되는 돌기체(100)와, 도 7a 및 도 7b에 도시된 것과 같이 레일(도 8의 부호 400 참조)을 설치하기 위한 침목(210)을 구비하며 종단부에는 각각 돌기체 삽입홈(210)이 형성되어 있는 슬라브 궤도(200)에 의해 구성된다.In the portion of the railway track to be constructed by the slab track, the conventional slab track system is a projection body 100 is installed in the civil engineering roadbed (B) of the track, as shown in Figs. 6a and 6b, and Figs. 7a and 7b. As shown in FIG. 8 is provided with a sleeper 210 for installing the rail (see reference numeral 400 of FIG. 8) and is formed by the slab raceway 200 is formed in each of the projection insertion groove 210 in the end portion.
특히, 상기 돌기체(100)의 형상은 원주형(圓柱形)으로 이루어져 있으며, 상기 돌기체 삽입홈(210)은 돌기체(100)의 원주면 절반부를 포용하는 반원주형 홈으로 이루어져 있다.In particular, the shape of the projection body 100 is formed in a columnar (圓柱形), the projection body insertion groove 210 is composed of a semi-circular groove that embraces half the circumferential surface of the projection body (100).
이와 같은 슬라브 궤도 시스템을 시공할 때는, 콘크리트로 돌기체(100)를 만들어 토목노반(B)에 설치한 뒤, 공장에서 제작한 콘크리트 슬라브 궤도(200)를 현장으로 운반하여 방진재로 방진처리를 한 다음, 슬라브 궤도(200)의 돌기체 삽입홈(200a)에 상기 돌기체(100)를 삽입시키는 방식에 따라 진행하게 된다.When constructing such a slab track system, the projecting body 100 is made of concrete and installed on a civil roadbed (B), and then the concrete slab tracks 200 manufactured at the factory are transported to the site for dustproof treatment with dustproof material. Next, the protrusion 100 is inserted into the protrusion insertion groove 200a of the slab raceway 200.
도 8에는 시공이 완료된 상태의 슬라브 궤도 시스템이 도시되어 있는데, 슬라브 궤도(200,200')의 돌기체 삽입홈(200a,200'a)과 돌기체(100) 사이에는 탄성체인 방진재(300)가 개재되며, 선로에 종방향 하중(선로방향 하중)이나 횡방향 하중이 작용할 때 상기 돌기체(100)와 방진재(300)의 대응하는 일부위만이 그 하중에 저항하게 된다.8 shows a slab track system in a completed construction state, between the protrusion insertion grooves 200a and 200'a of the slab tracks 200 and 200 'and the protrusion 100 interposed therebetween. When a longitudinal load (line load) or a lateral load is applied to the track, only a corresponding portion of the protrusion 100 and the dustproof member 300 resists the load.
즉, 도 9 및 도 10에 도시되어 있는 것처럼, 슬라브 궤도(200)에 종방향 하중(Wℓ) 또는 횡방향 하중(Wt)이 가해지는 경우, 하중(Wℓ,Wt)을 받는 측의 슬라브 궤도(200)가 탄성체인 방진재(300)를 변형시키면서 인근 슬라브 궤도(200')를 압박하여 도면에 점선으로 표시된 형태로 밀게 됨에 따라 노반에 고정되어 있는 돌기체(100)는 상기 방진재(300)측으로 반력(WR,WR')을 발생시키게 된다.That is, as shown in FIGS. 9 and 10, when the longitudinal load W ℓ or the transverse load W t is applied to the slab raceway 200, the side receiving the loads W ℓ and W t As the slab track 200 is deformed to the vibration-resistant material 300 is an elastic body of the slab track 200 'is pushed in the form indicated by the dotted line in the drawing as the projection body 100 is fixed to the roadbed is the dustproof material ( The reaction force (W R, W R ' ) is generated to the side 300.
이러한 작용 하중(Wℓ,Wt)과 반력(WR,WR')에 의해 상기 돌기체(100)와 방진재(300)는 극히 일부분에서만 접촉(극단적으로는 점접촉)을 하여 하중을 받게 되므로 이 접점에서 응력집중이 일어나 돌기체(100)와 방진재(300)를 취약하게 하고 결국 국부적인 손상을 일으키게 된다. Due to such an operating load (W ℓ, W t ) and reaction forces (W R, W R ' ), the protrusion body 100 and the dustproof material 300 are in contact with only a part (extreme point contact) to receive a load. Therefore, stress concentration occurs at this contact, which makes the protrusion 100 and the dustproof material 300 vulnerable, and eventually causes local damage.
이와 같이 종래의 슬라브 궤도 시스템은 작용 하중에 효과적으로 대응하지 못해 돌기체와 방진재의 국부적인 손상을 야기하여 잦은 유지보수를 필요로 하는 문제점을 갖고 있을 뿐만 아니라, 콘크리트로 원주형 돌기체를 시공하는 것이나 콘크리트 슬라브에 반원주형의 돌기체 삽입홈을 형성하는 것이 용이하지 않아 제작시 오차 발생률과 작업 난이도가 높다는 문제점도 있다.As such, the conventional slab track system does not respond effectively to the working load, causing local damage of the protrusion and the dustproof material, which requires frequent maintenance, and also requires the construction of cylindrical protrusions or concrete. It is not easy to form a semi-circular projection insertion groove in the slab, there is also a problem that the error occurrence rate and the difficulty of work during manufacturing.
본 고안은 전술한 바와 같은 문제점들을 해소하기 위해 안출된 것으로서, 그 목적은, 슬라브 궤도에 작용하는 하중으로 인한 돌기체와 방진재의 파손을 현저히 저감시킬 수 있는 철로용 슬라브 궤도 시스템의 구조를 제공하는 데에 있다.The present invention has been made to solve the problems described above, the object of which is to provide a structure of a slab track system for railway that can significantly reduce the damage of the projection body and the dustproof material due to the load acting on the slab track. There is.

And a rectangular parallelepiped shape formed at the center of the slab raceway.
이하, 본 고안의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
먼저, 도 1a 및 도 1b는 각각 본 고안에 따른 슬라브 궤도 시스템의 돌기체가 토목노반에 설치된 상태를 나타낸 정면도와 평면도로서, 본 고안의 돌기체(10)가 직사각형의 단면을 갖는 직육면체 형상으로 이루어져 있음을 보여주고 있다.First, Figures 1a and 1b is a front view and a plan view showing a state in which the protrusions of the slab track system according to the present invention is installed on a civil roadbed, respectively, the protrusions 10 of the present invention is formed in a rectangular parallelepiped shape having a rectangular cross section. Is showing.
즉, 실제 현장에서 토목노반(B)에 콘크리트로 성형되는 상기 돌기체(10)는 단면의 크기가 대략 가로 ×세로 = 500mm ×600mm인 직육면체로 이루어진다.That is, the protrusions 10 formed of concrete in the civil engineering subgrade B in an actual site are made of a rectangular parallelepiped having a cross-sectional size of approximately horizontal × vertical = 500 mm × 600 mm.
그리고, 도 2a와 도 2b에 도시된 바와 같이, 레일(도 3의 부호 40)이 설치될 침목(21)들을 구비한 본 고안의 슬라브 궤도(20)에는 상기 돌기체(10)가 삽입되는 돌기체 삽입홈(20a)이 형성되어 있다.And, as shown in Figures 2a and 2b, the stone (20) is inserted into the slab track 20 of the present invention having the sleepers 21 to be installed (reference numeral 40 of FIG. The gas insertion groove 20a is formed.
특히, 상기 돌기체 삽입홈(20a)은 상기 돌기체(10)의 크기 및 형상과 부합되는 직육면체 형상으로 이루어지며, 슬라브 궤도(20)의 중앙부에 위치하게 된다.In particular, the protrusion insertion groove 20a has a rectangular parallelepiped shape that matches the size and shape of the protrusion 10 and is positioned at the center of the slab track 20.
이와 같은 구조를 갖는 본 고안의 철로용 슬라브 궤도 시스템을 시공할 때는 다음과 시행하게 된다.When constructing a rail slab track system of the present invention having such a structure will be carried out as follows.
먼저, 선로의 노반에 콘크리트로 돌기체(10)를 직육면체 형상이 되도록 성형하여 설치한다.First, the protrusions 10 are formed in concrete on the roadbed of the track so as to have a rectangular parallelepiped shape.
아울러, 슬라브 궤도(20)의 중앙부에 상기 돌기체(10)의 형상과 부합하는 직육면체 형상의 돌기체 삽입홈(20a)을 공장에서 성형한 뒤, 상기 돌기체(10)가 설치된 현장의 선로로 운반한다.In addition, after forming a rectangular parallelepiped protrusion insertion groove 20a corresponding to the shape of the protrusion body 10 at the center of the slab raceway 20 at the factory, the track line of the site where the protrusion body 10 is installed To carry.
이때, 상기 돌기체(10)와 돌기체 삽입홈(20a)은 직사각형의 단면을 가지므로, 종래에 원형의 단면으로 형성할 때 보다 치수 정밀도를 높일 수 있고, 제작도 용이해진다는 것은 쉽게 예측할 수 있을 것이다.At this time, since the projection body 10 and the projection insertion groove 20a have a rectangular cross section, it can be easily predicted that the dimensional accuracy can be increased and the manufacturing becomes easier than when the circular body has a circular cross section. There will be.
이어서, 상기 슬라브 궤도(20)에 방진재를 포설하여 방진처리를 행하는데, 상기 방진재는 탄성계수가 0.1N/㎣정도로서 23mm두께로 포설하는 것이 적당하다.Subsequently, a dustproof material is installed on the slab raceway 20 to perform a dustproof process. The dustproof material is suitably laid at a thickness of 23 mm with an elastic modulus of about 0.1 N / ㎣.
이어서, 슬라브 궤도(20)의 돌기체 삽입홈(20a)에 상기 돌기체(10)가 삽입되도록 하여 슬라브 궤도(20)를 선로에 설치한다.Subsequently, the slab raceway 20 is installed in the track so that the protrusion body 10 is inserted into the protrusion insertion groove 20a of the slab raceway 20.
이와 같이 시공이 완료된 상태의 슬라브 궤도가 도 3에 도시되어 있는데, 도 8에 도시된 기존의 슬라브 궤도 및 돌기체의 구조와 차이가 있음을 알 수 있다.As described above, the slab track of the completed construction is shown in FIG. 3, but it can be seen that there is a difference from the structure of the existing slab track and the protrusion shown in FIG. 8.
즉, 본 고안의 돌기체(10)는 평면도상에서 직사각형으로 나타나며, 이 돌기체(10)를 수용하고 있는 슬라브 궤도(20)의 돌기체 삽입홈(20a) 역시 직사각형태를 띄게 된다.That is, the protrusion 10 of the present invention is shown as a rectangular in plan view, and the protrusion insertion groove 20a of the slab raceway 20 receiving the protrusion 10 also has a rectangular shape.
이에 따라, 슬라브 궤도(20)의 돌기체 삽입홈(20a)에 포설된 방진재(30)와 돌기체(10)는 넓은 면적에 걸쳐 면접촉을 하게 됨으로써, 슬라브 궤도(20)에 하중이 가해지는 경우, 이 하중에 대응하는 돌기체(10)와 방진재(30)의 범위가 커지게 된다.Accordingly, the dustproof material 30 and the protrusion 10 installed in the protrusion insertion groove 20a of the slab raceway 20 are brought into surface contact over a large area, whereby a load is applied to the slab raceway 20. In this case, the range of the projection body 10 and the dustproof material 30 corresponding to this load becomes large.
이에 대해서는 첨부도면 도 4와 도 5를 참조하며 설명한다.This will be described with reference to FIGS. 4 and 5.
도면에서와 같이, 슬라브 궤도(20)에 종방향 하중(Wℓ) 또는 횡방향 하중(Wt)이 가해지면, 하중(Wℓ,Wt)을 받은 슬라브 궤도(20)는 탄성체인 방진재(30)를 변형시키면서 도면에 점선으로 표시된 형태로 밀리게 된다.As shown in the drawing, when a longitudinal load (W L ) or a transverse load (W t ) is applied to the slab track (20), the slab track (20) under the load (W L, W t ) is made of an elastic dustproof material ( 30), it is pushed in the form indicated by the dotted line in the figure.
이에 따라 노반에 고정되어 있는 돌기체(10)는 상기 방진재(30)측으로 반력(WR,WR')을 발생시키며 하중(Wℓ,Wt)에 저항하게 된다.Accordingly, the protrusion 10 fixed to the roadbed generates reaction forces W R and W R ' toward the dustproof material 30 and resists the loads W 1 and W t .
이때, 상기 돌기체(10)에 의해 발생하는 반력(WR,WR')은 돌기체(10)와 방진재(30)의 서로 마주보는 면에 작용하는 하중을 균일하게 분산시키며 많은 면적이 작용하중에 저항함으로써 돌기체(10)와 방진재(30)의 특정 지점에만 응력이 집중되는 현상이 현저히 완화된다.At this time, the reaction forces (W R, W R ' ) generated by the projection body 10 uniformly distributes the load acting on the surfaces facing each other of the projection body 10 and the dustproof material 30, and a large area acts By resisting the load, the phenomenon in which stress is concentrated only at specific points of the protrusion 10 and the dustproof material 30 is remarkably alleviated.
따라서, 종래에 돌기체와 방진재가 극히 일부분에서만 접촉을 하여 하중을 받게 됨으로 인해 일어나는 응력집중현상이 본 고안에서는 배제됨으로써, 돌기체(10)와 방진재(30)의 취화나 손상이 방지된다.Therefore, in the present invention, the stress concentration phenomenon caused by the projection body and the dustproof material being in contact with only a part of the load and being subjected to a load is excluded in the present invention, so that embrittlement or damage of the projection body 10 and the dustproof material 30 is prevented.
이상에서 설명한 바와 같이, 본 고안은 다음과 같은 효과를 갖게 된다.As described above, the present invention has the following effects.
첫째, 슬라브 궤도에 작용하는 하중에 의한 응력집중현상이 배제됨으로써 돌기체와 방진재의 파손이 현저히 저감되고, 유지보수비를 절감할 수 있게 된다.First, the stress concentration phenomenon due to the load acting on the slab track is excluded, the breakage of the projection body and the dustproof material is significantly reduced, it is possible to reduce the maintenance cost.
둘째, 돌기체와 돌기체 삽입홈의 정밀도를 높일 수 있어 제작과 시공이 용이하게 이루어지며, 공사비가 절감된다.Second, it is possible to increase the precision of the projection body and the projection insertion groove made easy to manufacture and construction, and the construction cost is reduced.
