또, 결합돌기는 철도차량용 제2구조물이 압출되는 길이방향으로 연장되어 있어 결합돌기가 결합홈에 삽입되는 방향이나 그 반대방향으로 이동되어야 결합홈에서 결합돌기가 이탈될 수 있도록 된 형태이다.
In addition, the coupling protrusion extends in the lengthwise direction in which the second structure for the railway vehicle is extruded so that the coupling protrusion may be removed from the coupling groove only when the coupling protrusion is moved in the direction in which the coupling protrusion is inserted into the coupling groove or in the opposite direction thereof.

본 발명의 철도차량용 구조물 슬롯결합 구조는, 홈에 돌기가 삽입되어 결합되는 슬롯결합 방식을 통해 금속재질의 철도차량용 구조물 간에 결합이 이루어지도록 되어 있고, 결합돌기가 결합홈에 삽입되는 방향이나 그 반대방향으로 이동되어야 결합홈에서 결합돌기가 이탈될 수 있도록 된 형태이기 때문에 견고한 결합이 가능할 뿐만 아니라 철도차량용 구조물의 결합 작업이 용이하고, 결합부에서의 강도저하 현상이 발생되지 않으며, 철도차량 개조와 유지, 보수성이 우수한 특징이 있다.The railway vehicle structure slot coupling structure of the present invention is to be coupled between the structure of the railway vehicle structure of the metal material through the slot coupling method in which the projection is inserted into the groove, the direction in which the coupling projection is inserted into the coupling groove or vice versa Because it is a form that the coupling protrusion can be separated from the coupling groove only when moving in the direction, it is not only possible to secure the coupling but also to facilitate the coupling work of the railway vehicle structure, and the strength reduction phenomenon at the coupling portion does not occur.

이하, 본 발명의 기술적 사상을 첨부된 도면을 사용하여 더욱 구체적으로 설명한다. Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

그러나 첨부된 도면은 본 발명의 기술적 사상을 더욱 구체적으로 설명하기 위하여 도시한 일 예에 불과하므로 본 발명의 기술적 사상이 첨부된 도면의 형태에 한정되는 것은 아니다.It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

본 발명은 철도차량의 구현을 위한 금속재질의 철도차량 구조물 간의 결합구조 관한 것이다. The present invention relates to a coupling structure between the railroad car structure of the metal material for the implementation of the railroad car.

즉, 금속재질의 철도차량용 제1구조물(10)과 금속재질의 철도차량용 제2구조물(20)을 결합하는 구조에 관한 것이다.That is, the present invention relates to a structure in which the first structure 10 for a railroad car of metal material and the second structure 20 for a railroad car of metal material are combined.

그런데 본 발명은 철도차량용 구조물의 결합 작업이 용이하고, 결합부에서의 강도저하 현상이 발생되지 않으며, 차량 개조와 유지, 보수성이 우수한 철도차량을 제공하려는 목적을 갖는다.However, the present invention has an object of providing a railway vehicle easy to combine the structure for the railway vehicle structure, the strength reduction phenomenon in the coupling portion does not occur, and excellent vehicle remodeling, maintenance, repairability.

용접을 통한 결합방식으로는 상기와 같은 목적을 달성할 수 없어 본 출원의 발명자는 홈과 돌기를 사용한 슬롯결합 방식을 안출하였다.The welding method can not achieve the above object by the welding method, the inventor of the present application devised a slot coupling method using a groove and a projection.

즉, 금속 재질의 철도차량용 제1구조물(10)에 형성된 결합홈(11)에 금속재질의 철도차량용 제2구조물(20)에 형성된 결합돌기(21)가 삽입되어 철도차량용 제1구조물(10)과 철도차량용 제2구조물(20) 간의 결합이 이루어지도록 하는 것이다.That is, the coupling protrusion 21 formed in the second structure 20 of the metal railway vehicle is inserted into the coupling groove 11 formed in the first structure 10 of the metallic railway vehicle, thereby inserting the first structure 10 for the railway vehicle. And the coupling between the second structure 20 for a railway vehicle.

그런데 철도차량의 특성상 결합부에서의 견고한 결합이 요구될 뿐만 아니라 철도차량용 구조물은 압출에 의해 제작되는 특징이 있다.By the way, due to the characteristics of the railway vehicle, not only a rigid coupling is required at the coupling portion, but also a railway vehicle structure is characterized by being manufactured by extrusion.

이로 인하여, 상기 결합홈(11)은 3면이 막힌 형상을 가지면서 철도차량용 제1구조물(10)이 압출되는 길이 방향으로 연장된 형상을 갖는다.For this reason, the coupling groove 11 has a shape in which three surfaces are blocked and extends in the lengthwise direction in which the first structure 10 for a railway vehicle is extruded.

또, 결합돌기(21)는 철도차량용 제2구조물(20)이 압출되는 길이방향으로 연장되어 있다. In addition, the engaging projection 21 extends in the longitudinal direction from which the second structural body 20 for rolling stock is extruded.

따라서 결합돌기(21)가 결합홈(11)에 삽입되는 방향이나 그 반대방향으로 이동되어야 결합홈(11)에서 결합돌기(21)가 이탈될 수 있다. Therefore, the coupling protrusion 21 may be separated from the coupling groove 11 only when the coupling protrusion 21 is moved in the direction in which the coupling protrusion 21 is inserted or the opposite direction thereof.

상기와 같은 결합홈(11)이나 결합돌기(21)는 철도차량용 제1구조물(10)이나 철도차량용 제2구조물(20)의 압출성형시 형성할 수 있는 특징이 있다.
The coupling groove 11 or the coupling protrusion 21 as described above may be formed during extrusion of the first structure 10 for a railway vehicle or the second structure 20 for a railway vehicle.

철도차량용 구조물 간의 더욱 견고한 결합을 위해서, 첨부된 도면에서와 같이 철도차량용 제2구조물(20)에는 결합홈(22)(전술한 철도차량용 제1구조물(10)에 형성된 것과 같은 형태의 결합홈)이 형성되어 있고 상기 철도차량용 제1구조물(10)에는 철도차량용 제2구조물(20)에 형성된 결합홈(211)에 삽입되어 결합되는 결합돌기(12)(전술한 철도차량용 제2구조물(20)에 형성된 것과 같은 형태의 결합돌기가 형성되어 있도록 할 수 있다.
For a more robust coupling between the railway vehicle structures, as shown in the accompanying drawings, the second structure 20 for railway vehicles has a coupling groove 22 (coupling grooves of the same type as that formed in the first structure 10 for railway vehicles described above). Is formed and the first structure 10 for the railway vehicle is inserted into the coupling grooves (211) formed in the coupling groove 211 formed in the second structure 20 for railway vehicles (second structure 20 for the railway vehicle described above). The coupling protrusion of the same type as that formed in the can be formed.

본 발명에 있어서, 철도차량용 제1구조물(10)과 철도차량용 제2구조물(20)에 핀구멍(13, 23)이 형성되어 있도록 하고, 이 핀구멍(13, 32)에 핀(30)을 박아 결합상태의 변형이 발생되는 것을 방지할 수도 있다.In the present invention, the pin holes 13 and 23 are formed in the first structure 10 for railroad cars and the second structure 20 for railroad cars, and the pins 30 are formed in the pinholes 13 and 32. It is also possible to prevent deformation of the driving state.

즉, 결합 상태의 철도차량용 제1구조물(10)과 철도차량용 제2구조물(20)에 상호 일치되는 핀구멍(13 과 23)이 형성되어 있고, 이 핀구멍(13, 23)에 핀(30)을 박아 결합 상태에 변형이 발생되는 것을 방지하는 것이다. That is, the pinholes 13 and 23 which are mutually matched are formed in the 1st structure 10 for railroad cars and the 2nd structure 20 for railroad cars, and the pin 30 is formed in these pinholes 13 and 23. ) To prevent deformation in the bonded state.

이러한 핀구멍(13, 23)은 소정의 간격을 두고 복수 개 형성되어 있도록 하는 것이 좋다.
It is preferable that a plurality of such pinholes 13 and 23 be formed at predetermined intervals.

본 발명은 결합홈(11, 22)과 결합돌기(12, 21)를 사용한 슬롯결합 방식인데 결합의 용이성을 위해서는 결합돌기(21)의 크기가 결합홈(11)보다 작아야 한다.The present invention is a slot coupling method using the coupling grooves (11, 22) and coupling protrusions (12, 21) for the ease of coupling, the size of the coupling protrusion 21 should be smaller than the coupling groove (11).

그런데 이러한 방식에서는 결합홈(11)과 결합돌기(21) 사이에 틈새가 발생될 수 밖에 없다.In this manner, however, a gap is generated between the coupling groove 11 and the coupling protrusion 21.

상호 결합되는 결합홈(11)과 결합돌기(21) 사이에 틈새가 크게 발생 될수록 진동과 소음이 크다.The greater the gap between the coupling groove 11 and the coupling protrusion 21 which are coupled to each other, the greater the vibration and noise.

이러한 문제점 해소를 위하여 상호 결합되는 결합홈(11)과 결합돌기(21) 사이에 접착제(40)가 채워져 결합홈(11)과 결합돌기(21) 사이의 틈새가 메워지는 구조를 안출하였다.In order to solve this problem, the adhesive 40 is filled between the coupling grooves 11 and the coupling protrusions 21 that are coupled to each other, thereby creating a structure in which a gap between the coupling grooves 11 and the coupling protrusions 21 is filled.

이러한 접착제(40)는 결합홈(11)과 결합돌기(21)를 결합하기 전에 결합홈(11)이나 결합돌기(21)에 두껍게 도포해 놓고 결합하는 방식으로 위치시킬 수 있다.The adhesive 40 may be disposed in such a manner that the adhesive grooves are thickly applied to the coupling grooves 11 or the coupling protrusions 21 before the coupling grooves 11 and the coupling protrusions 21 are coupled.

그러나 이러한 방식은 결합홈(11)과 결합돌기(21) 사이의 틈새를 견고하게 메워주지 못하는 문제가 있다. However, this method has a problem in that the gap between the coupling groove 11 and the coupling protrusion 21 is not firmly filled.

따라서 결합홈(11, 22)과 결합돌기(21, 12)를 결합시켜 놓은 후 결합홈(11)과 결합돌기(21)의 측면(결합 상태의 철도차량용 제1구조물(10)과 철도차량용 제2구조물(20)의 측면)에서 접착제를 밀어넣는 방식을 사용하는 것이 더 좋다. Therefore, the coupling grooves 11 and 22 and the coupling protrusions 21 and 12 are coupled, and then the side surfaces of the coupling groove 11 and the coupling protrusion 21 (the first structure 10 for the railway vehicle in the coupled state and the agent for the railway vehicle). It is better to use a method of pushing the adhesive on the side of the structure (20).

그런데 철도차량용 구조물은 그 길이가 평균 20m 이상으로 매우 길다.However, the structure of railway vehicles is very long, the average length of more than 20m.

따라서 결합 상태의 철도차량용 제1구조물(10)과 철도차량용 제2구조물(20)의 측면에서 접착제를 밀어 넣는 방식은 접착제를 매우 강한 압력으로 밀어넣기 위한 수단이 요구된다.Therefore, the method of pushing the adhesive on the side of the first structure 10 for railroad car and the second structure 20 for railroad car in a coupled state requires a means for pushing the adhesive to a very strong pressure.

이러한 문제점 해소를 위해 철도차량용 제1구조물(10)이나 철도차량용 제2구조물(20)에 형성된 구멍에 접착제를 밀어 넣는 방식을 사용할 수 있다.In order to solve such a problem, a method of pushing an adhesive into a hole formed in the first structure 10 for a railway vehicle or the second structure 20 for a railway vehicle may be used.

이러한 구멍은 전술한 설명에서 핀(30)을 박기 위한 핀구멍(13, 23)일 수 있다. Such a hole may be pin holes 13 and 23 for driving the pin 30 in the above description.

접착제를 밀어 넣기 위한 홀은 소정의 간격으로 복수 개 형성되어 있는 것이 좋다. It is preferable that a plurality of holes for pushing the adhesive be formed at predetermined intervals.

핀구멍(13, 23)으로 접착제를 밀어 넣었을 때 접착제가 결합홈(11)과 결홀돌기 사이의 틈새로 퍼져나가도록 하기 위해서 핀구멍(13, 23)의 입구 맞은편(핀구멍(13, 23)이 상부로에서 하부로 형성된 경우 핀구멍(13, 23)의 하부, 반대로 핀구멍(13, 23)이 하부에서 상부로 형성된 경우 핀구멍(13, 23)의 상부)이 막혀있도록 한다.
Opposite the inlet of the pinholes 13, 23 (pinholes 13, 23) so that when the adhesive is pushed into the pinholes 13, 23, the adhesive spreads into the gap between the coupling groove 11 and the indentation protrusion. ) Is formed from the upper to the lower portion of the pin hole (13, 23), on the contrary, if the pin hole (13, 23) is formed from the bottom to the upper portion of the pin hole (13, 23) to be blocked.

본 발명에 있어서, 결합홈(11, 22)과 결홀돌기(12, 21)에 의한 결합부는 마주하는 방향에 각각 형성되는 것이 좋다.In the present invention, it is preferable that the coupling portions formed by the coupling grooves 11 and 22 and the concavity protrusions 12 and 21 are respectively formed in opposite directions.

즉, 상부와 하부에 모두에 형성되거나 좌측과 우측 모두에 각각 형성되도록 하는 것이다.
That is, to be formed on both the top and bottom or to be formed on both the left and right.
