Description
본 발명은 교량의 선단에 설치되어, 교량들을 상호 신축가능하게 연결하면서 교량간의 이격공간으로의 하중을 지지하는 교량연결용 핑거블록에 관한 것으로, 이의 제조가 편리하고 다양한 형태로의 구조변경이 용이한 교량연결용 핑거블록에 관한 것이다.The present invention relates to a finger block for bridge connection, which is installed at the tip of a bridge and supports the loads to the spaced space between the bridges while connecting the bridges in a flexible manner, and is easy to manufacture and easily change the structure in various forms. It relates to a bridge block finger block.
교각의 상부에 얹혀지는 교량은, 계절변화에 따른 온도차에 의해서 자연스럽게 교축방향으로의 길이가 신장되거나 축소되고, 또한 교량에 가해지는 하중 및 바람 등의 외력에 의해서 강제적으로 교축방향으로의 길이가 신장되거나 축소되므로, 상호 맞대어지는 교량의 선단 간에는 교축방향으로의 길이변화를 위한 이격거리를 두어야 한다.Bridges placed on the upper part of the bridge naturally extend or shorten in the axial direction due to the temperature difference according to the seasonal change, and the length in the axial direction is forcibly extended by external forces such as load and wind applied to the bridge. As it is either reduced or reduced, a distance between the ends of the bridges which are opposed to each other should be provided for the change of length in the direction of the bridge.
교량이 교축방향으로 신장되어서 상호 맞대어진 교량의 선단이 서로 근접된경우에는 차량이 교량연결부분을 원활하게 주행할 수 있지만, 교량이 교축방향으로 축소되어서 상호 맞대어진 교량의 선단 간의 이격거리가 확장된 경우에는 차량의 바퀴가 교량연결부분에 간섭되어 차량 승차감이 크게 저하되며, 더욱이 교축방향으로의 신축길이변화가 이보다 더욱 크다면(교량의 교축방향으로의 길이가 길수록 신축길이변화는 커진다) 교량간의 이격거리가 더욱 커지게 되므로, 차량의 바퀴가 교량연결부분에 완전히 빠지게 되는 심각한 문제가 발생된다.If the bridges extend in the direction of the bridge and the ends of the bridges are in close proximity to each other, the vehicle can smoothly run the bridge joints, but the bridge is reduced in the direction of the bridges so that the separation distance between the bridges of the bridges is extended In this case, the wheel of the vehicle interferes with the bridge connection part, and the ride comfort is greatly reduced. Furthermore, if the extension length in the bridge direction is greater than this (the longer the bridge length is in the bridge direction, the larger the extension length is). As the separation distance between them becomes larger, a serious problem arises that the wheels of the vehicle fall completely into the bridge connecting portion.
따라서, 교량의 선단에 별도의 교량연결기구를 설치하여 상호 맞대어지는 교량간의 이격공간으로의 하중이 교량연결기구에 의해서 지지되도록 해야 한다.Therefore, a separate bridge connecting mechanism should be provided at the tip of the bridge so that the load to the spaced space between the mutually opposing bridges is supported by the bridge connecting mechanism.
교량들을 상호 신축가능하게 연결하면서 교량간의 이격공간으로의 하중을 지지하는 교량연결구조는, 이미 다양하게 제안되어 널리 사용되고 있으며, 레일을 교량연결기구로 이용하는 레일식 교량연결구조와, 핑거블록을 교량연결기구로 이용하는 핑거블록식 교량연결구조가 대표적이라 할 수 있다.The bridge connecting structure for supporting the loads to the spaces between the bridges while flexibly connecting the bridges has already been proposed and widely used, and the rail type bridge connecting structure using the rail as the bridge connecting mechanism, and the finger block bridge The finger block type bridge connecting structure used as a connecting mechanism is representative.
상기 레일식 교량연결구조는 이에 사용되는 부재수가 다소 많다고 할 수 있고, 또한 부재들간의 상호 조립작업이 번거롭다고 할 수 있지만, 부재들의 제조가 용이하여 아직도 널리 사용되고 있다.The rail-type bridge connecting structure can be said to have a somewhat larger number of members, and it can be said that the mutual assembly work between the members is cumbersome, but the manufacture of the members is still widely used.
하지만, 이러한 레일식 교량연결구조는 교량연결기구로 레일을 이용하고 있고, 이들 레일이 교축방향의 직각방향으로, 다시말해서 교량의 폭방향으로 배치되는 구조를 이루고 있어서, 차량이 이를 통과할 때 레일과 차량 바퀴와의 간섭이 심하게 발생되므로, 차량의 승차감 저하가 초래되고, 간섭으로 인한 이음이 크게 발생되는 문제가 초래되는 단점이 있다.However, such a rail-type bridge connecting structure uses a rail as a bridge connecting mechanism, and these rails form a structure arranged in a direction perpendicular to the bridge direction, that is, in the width direction of the bridge, so that the rail when the vehicle passes therethrough Since the interference with the vehicle wheels is severely generated, the ride comfort of the vehicle is lowered, and the problem that the joint is greatly generated due to the interference is caused.
상기 레일식 교량연결구조의 단점을 해소하기 위해 핑거블록식 교량연결구조가 제안되었는데, 이에 대한 설명은 도 1a 내지 도 1c를 참조하여 보다 상세히 설명한다.In order to solve the shortcomings of the rail type bridge connection structure, a finger block type bridge connection structure has been proposed, which will be described in more detail with reference to FIGS. 1A to 1C.
도 1a 및 도 1b에 의하면, 종래 핑거블록식 교량연결구조는, 상호 맞대어지는 교량(BG ; BG')의 선단 보강부(C2) 상면에 베이스패널(5)이 각각 안착되고, 한 쌍의 핑거블록(20 ; 20')이 서로 대향되게 배치되어 상호 맞물리도록 베이스패널(5)에 각각 얹혀지며, 앵커 등의 고정부재(F1)를 매개로 베이스패널(5)과 핑거블록(20 ; 20')이 교량(BG ; BG')의 선단 보강부(C2)에 고정되는 한편, 물받이용 패널(400)의 양쪽 선단이 앵커 등의 고정부재(F2)를 매개로 상호 맞대어지는 교량(BG ; BG')의 보강부(C2) 선단면에 각각 체결되어진 구조를 이룬다.1A and 1B, in the conventional finger block type bridge connection structure, the base panel 5 is respectively seated on the upper surface of the tip reinforcement portion C2 of the bridge BG; Blocks 20 and 20 'are placed on the base panel 5 so as to be opposed to each other and interlock with each other, and the base panel 5 and the finger blocks 20 and 20' are provided through fixing members F1 such as anchors. ) Is fixed to the tip reinforcement portion C2 of the bridge (BG; BG '), while both ends of the drip panel 400 are butted to each other via a fixing member F2 such as an anchor (BG; BG). It forms a structure that is respectively fastened to the end surface of the reinforcement portion (C2) of the ').
상기 핑거블록(20 ; 20')은, 도 1c에 도시된 바와 같이, 체결구멍(21a)이 형성되어진 본체부(21)로부터 핑거부(22)가 등간격을 이루면서 돌출되어, 핑거부(22)들 사이에 핑거삽입홈(H1)이 형성되어진 구조를 이룬다.As illustrated in FIG. 1C, the finger blocks 20 and 20 ′ protrude from the main body portion 21 in which the fastening holes 21 a are formed, with the finger portions 22 at equal intervals, and the finger portions 22. Finger insertion groove (H1) is formed between the) forms a structure.
교량(BG ; BG')간의 이격거리(L)가 근접되어지면, 한쪽 교량(BG)에 설치되어진 핑거블록(20)의 핑거부(22)가 다른 한쪽 교량(BG')에 설치되어진 핑거블록(20')의 핑거삽입홈(H1)으로 삽입되면서, 한쪽 교량(BG)에 설치되어진 핑거블록(20)의 핑거삽입홈(H1)에 다른 한쪽 교량(BG')에 설치되어진 핑거블록(20')의 핑거부(22)가 삽입되어, 두 손으로 깍지를 끼듯이 한 쌍의 핑거블록(20 ; 20')이 상호 맞물리게 된다. 한편, 교량(BG ; BG')간의 이격거리(L)가 멀어지게 되면, 이에 설치되어진 한 쌍의 핑거블록(20 ; 20')이 서로 벌어지게 되는데, 한 쌍의 핑거블록(20 ; 20')이 서로 벌어지더라도, 이들 핑거블록(20 ; 20')의 핑거부(22)들이 교축방향의 직각방향으로 서로 대향되게 나란히 배치되면서 교량(BG ; BG')간의 이격공간으로의 하중을 지지하게 된다.When the separation distance L between the bridges BG and BG 'approaches, the finger block 22 of the finger block 20 installed on one bridge BG is provided on the other bridge BG'. Finger block 20 installed in the other bridge BG 'in the finger insertion groove H1 of the finger block 20 installed in one bridge BG while being inserted into the finger insertion groove H1 of 20'. ') Is inserted into the finger 22, a pair of finger blocks (20; 20') are engaged with each other like a pod with two hands. On the other hand, when the separation distance (L) between the bridge (BG; BG ') is far apart, a pair of finger blocks (20; 20') installed therein are separated from each other, a pair of finger blocks (20; 20 ') ), The fingers 22 of these finger blocks 20; 20 'are arranged side by side to face each other in the direction perpendicular to the axial direction, and support the load to the space between the bridges BG; BG'. Done.
따라서, 차량이 교량(BG ; BG')의 연결부분을 주행하게 되면, 차량바퀴가 한 쌍의 핑거블록(20 ; 20')을 통과하게 되는데, 이의 핑거부(22)들이 교량의 교축방향으로 돌출되어 있고, 이의 핑거삽입홈(H1) 역시 교량의 교축방향으로 돌출되어 있으므로, 차량바퀴가 이들 핑거블록(20 ; 20') 위를 자연스럽게 통과하게 되어, 승차감의 저하가 방지되고, 간섭으로 인한 이음발생이 크게 감소된다.Therefore, when the vehicle travels through the connecting portion of the bridge BG (BG '), the vehicle wheel passes through the pair of finger blocks 20 and 20', the finger portions 22 of which are directed in the bridge direction of the bridge. Since the protruding and the finger insertion groove (H1) also protrudes in the bridge axial direction, the vehicle wheel naturally passes over these finger blocks (20; 20 '), to prevent the deterioration of ride comfort, due to interference The occurrence of joints is greatly reduced.
그러나, 상기 종래 기술에 따른 핑거블록(20 ; 20')은, 본체부(21)와 핑거부(22)가 일체로 형성되어 있어서, 제조상의 어려움으로 인해 제품비용이 상당히 비싸고, 다양한 형태로의 구조변경이 사실상 불가능하여, 핑거블록의 사용이 제한되는 문제가 발생된다.However, the finger blocks 20 and 20 'according to the prior art have a main body portion 21 and a finger portion 22 formed integrally, so that the product cost is considerably high due to manufacturing difficulties, Since the structural change is virtually impossible, a problem arises in that the use of the finger block is restricted.
이에 대해 보다 상세히 설명해 보면, 종래 핑거블록(20 ; 20')은 앞서 언급한 바와 같이 본체부(21)와 핑거부(22)가 일체로 형성되어 있어서, 육면체 블록형태의 금속재료를 공작기계로 절삭하거나, 산소용접으로 절개하여 핑거블록(20 ; 20')을 제조하고 있는데, 이 작업이 사실상 매우 어려워서 제품비용 상승의 주요 원인이 되고 있다.In detail, the conventional finger blocks 20 and 20 'are formed integrally with the main body portion 21 and the finger portion 22 as mentioned above, so that a metal material in the form of a hexahedral block is used as a machine tool. Cutting or cutting with oxygen welding to produce a finger block (20; 20 '), which is very difficult in practice, which is a major cause of the increase in product cost.
더욱이, 핑거블록(20 ; 20')의 세로높이(T3)가 클수록 절삭이나 절개작업이더욱 어려워지므로, 핑거블록(20 ; 20')의 세로높이(T3)가 크게 제약될 수 밖에 없고, 절삭이나 절개작업의 공수를 줄이기 위해서는 핑거부(22)의 폭(W3)을 넓게 할 수 밖에 없다. 따라서, 핑거블록(20 ; 20')의 다양한 형태로의 구조변경이 사실상 불가능하다고 할 수 있다.Moreover, the larger the vertical height T3 of the finger blocks 20 and 20 ', the more difficult the cutting or cutting operations are. Therefore, the vertical height T3 of the finger blocks 20 and 20' is inevitably constrained. In order to reduce the man-hours of cutting or cutting operation, the width W3 of the finger portion 22 must be widened. Therefore, it can be said that the structural changes to various forms of the finger blocks 20 and 20 'are virtually impossible.
이에 본 발명은 상기와 같은 문제를 해소하기 위해 발명된 것으로, 쉽게 제조할 수 있고, 다양한 형태로의 구조변경이 용이한 교량연결용 핑거블록을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, and an object thereof is to provide a bridge block finger block that can be easily manufactured and easily changed in various forms.

본 발명에 따른 핑거블록(200,200')은, 비록 각 구성요소들(210,220,231,232)을 상호 조립해야하는 번거로움이 있지만, 이들 구성요소(210,220,231,232)를 손쉽게 제작할 수 있어서, 적은 비용으로 많은 핑거블록(200,200')을 제조할 수 있게 된다. 또한, 각 지지편(210,220)들의 성형이 자유로워서 핑거블록(200,200')을 보다 다양한 형태로 손쉽게 구조변경할 수 있게 된다. 한편, 제1지지편(210)과 제2지지편(220)이 모두 교축방향으로 배치되므로, 제1지지편(210)의 핑거부(212)와 핑거삽입홈(H1)도 교축방향으로 배치되어, 차량바퀴가 이들 핑거블록(200 ; 200') 위를 자연스럽게 통과하게 된다. 따라서, 승차감의 저하나, 간섭으로 인한 이음발생등의 문제는 초래되지 않는다.Finger blocks 200, 200 'according to the present invention, although it is cumbersome to assemble each of the components (210, 220, 231, 232), it is easy to manufacture these components (210, 220, 231, 232), so that many finger blocks (200, 200') at a low cost ) Can be manufactured. In addition, the molding of the support pieces 210 and 220 is free, so that the finger blocks 200 and 200 'can be easily changed in various forms. On the other hand, since both the first support piece 210 and the second support piece 220 are disposed in the axial direction, the finger portion 212 and the finger insertion groove H1 of the first support piece 210 are also disposed in the axial direction. As a result, the vehicle wheel naturally passes over these finger blocks 200 (200 '). Therefore, problems such as deterioration of ride comfort and noise generation due to interference are not caused.
도 2a 내지 도 2c에 도시되어진 실시예의 경우에는, 제1지지편(210)의 세로높이(T1)를 제2지지편(220)의 세로높이(T2)보다 낮게 형성하여, 제2지지편(220)의 저면부가 제1지지편(210)의 접합부(211)로부터 하방향으로 돌출되도록 하였다.2A to 2C, the vertical height T1 of the first support piece 210 is lower than the vertical height T2 of the second support piece 220, so that the second support piece ( The bottom portion of the 220 is projected downward from the junction portion 211 of the first support piece 210.
이러한 경우, 제조가 상당히 편리하다는 장점이 있지만, 하중을 안정적으로 지지하기에는 다소 불리한 구조를 이루게 되는 단점이 있다.In this case, there is an advantage that the manufacturing is quite convenient, but there is a disadvantage that a somewhat disadvantageous structure to support the load stably.
이에 대해서 보다 상세히 설명해 보면, 제1지지편(210)의 세로높이(T1)와 제2지지편(220)의 세로높이(T2)가 각각 길이 전체에 걸쳐서 동일하므로, 이들의 제조시 금속판재를 길이방향으로 절단하는 단일작업으로 제1지지편(210)과제2지지편(220)의 밑면을 손쉽게 처리할 수 있게 된다. 반면, 제1지지편(210)에 전해지는 하중은 조립용 바아(231,232)를 통해서 제2지지편(220)으로 전달되므로, 조립용 바아(231,232)의 변형·파손이 초래되고, 핑거블록(200,200')에 가해지는 전체하중을 제2지지편(220)이 모두 지지해야 한다. 따라서, 제2지지편(220)과 이를 받치고 있는 베이스패널(100)의 경계면에 집중응력이 가해지게 되고, 이로 인해서 베이스패널(100)이 변형·파손되거나, 핑거블록(200,200')의 수명이 단축되는 문제가 야기된다.In detail, the vertical height T1 of the first support piece 210 and the vertical height T2 of the second support piece 220 are the same over the entire length, so that the metal sheet material is It is possible to easily process the bottom surface of the first support piece 210 and the second support piece 220 in a single operation to cut in the longitudinal direction. On the other hand, since the load transmitted to the first support piece 210 is transmitted to the second support piece 220 through the assembly bars 231 and 232, deformation and breakage of the assembly bars 231 and 232 are caused, and the finger block ( The second support piece 220 must support all the loads applied to the 200, 200 '). Therefore, concentrated stress is applied to the interface between the second support piece 220 and the base panel 100 supporting the base plate 100, and thus, the base panel 100 is deformed or damaged, or the life of the finger blocks 200 and 200 'is extended. The problem of shortening is caused.
한편, 도 3a 및 도 3b는 본 발명에 따른 핑거블록의 다른 일예를 도시하고 있는 바, 이에 의하면, 상기 제1지지편 접합부(211)의 세로높이(T1')가 제2지지편(220)의 세로높이(T2)와 동일하고, 제1지지편 핑거부(212)의 세로높이(T1)가 접합부(211)의 세로높이(T1')보다 낮게 형성되어, 제1지지편 핑거부(212)와 제2지지편(220)이 서로 상응하게 맞대어진 구조를 이룬다.Meanwhile, FIGS. 3A and 3B show another example of the finger block according to the present invention, whereby the vertical height T1 ′ of the first support piece joining portion 211 is the second support piece 220. It is equal to the vertical height (T2) of, the vertical height (T1) of the first supporting piece finger portion 212 is formed lower than the vertical height (T1 ') of the bonding portion 211, the first supporting piece finger portion 212 ) And the second support piece 220 are formed to correspond to each other correspondingly.
본 실시예에 따르면, 제1지지편(210)의 밑면처리가 다소 복잡하게 되어 제조가 상대적으로 복잡해진다는 단점이 있지만, 제1지지편(210)에 가해진 하중은 제1지지편(210)의 접합부(211)를 통해서 베이스패널(100)로 전달되고, 제2지지편(220)에 가해진 하중은 제2지지편(220)을 통해서 베이스패널(100)로 전달되므로, 조립용 바아(231,232)로의 하중전달이 방지되면서, 하중에 의한 응력집중이 가능한 한 억제되는 잇점이 있다.According to the present embodiment, the bottom surface treatment of the first support piece 210 is somewhat complicated, so that manufacturing is relatively complicated. However, the load applied to the first support piece 210 is the first support piece 210. It is transmitted to the base panel 100 through the junction portion 211 of the, the load applied to the second support piece 220 is transmitted to the base panel 100 through the second support piece 220, the assembly bars (231,232) While the load transfer to () is prevented, the stress concentration by the load is suppressed as much as possible.
