본 발명은 교량용 신축이음장치에 관한 것으로, 보다 상세하게는 온도변화 등에 의한 전,후 방향 및 좌,우 방향 신축과, 지점침하 등에 의한 상,하 방향 단차와, 지진이나 토압변화에 의해 발생한 불규칙한 변위를 수용하면서도, 교량상판(1)의 연속성을 유지시켜주며, 보수교체도 용이한 교량용 신축이음 장치에 관한 것이다.More particularly, the present invention relates to an expansion joint device for a bridge, and more particularly to an expansion joint device for a bridge, To an expansion joint device for a bridge which maintains continuity of the bridge upper plate (1) while accommodating irregular displacements and is easy to change maintenance.

일반적으로 신축이음장치를 선정함에 있어서 가장 중요한 설계조건으로는 교축방향으로의 온도변화, 콘크리트의 크리프 및 건조수축에 의한 신축량과 교량의 회전변위 및 처짐량, 그리고 구조적으로 필요한 여유량 등이 있으며, 이러한 조건들은 대부분 교축방향을 대상으로 정의된 것이며, 현재 신축이음장치에 대한 설계방법도 계산된 교축방향 신축량을 수용할 수 있는 신축이음 장치를 선정하는 정도에 머물러 있으며, 교축직각방향의 신축에 대해서는 전혀 고려하지 않는 것이 일반 적이다. 그리고 지진시에 교축직각방향으로 변위가 발생할 경우 신축이음장치가 파손되는 것을 허용하고 있는 실정이다.In general, the most important design conditions for selecting the expansion joint are the temperature change in the throttling direction, the expansion and contraction due to the creep and shrinkage of the concrete, the rotational displacement and deflection of the bridge, The design method for the expansion joint remains at the level of selecting the expansion joint device capable of accommodating the calculated expansion direction of the expansion direction and there is no consideration for the expansion and contraction in the direction perpendicular to the expansion direction It is common not to. In case of displacement in the direction perpendicular to the throttle at the time of earthquake, the expansion joint is allowed to break.

또한, 사교나 곡선교에서처럼 고정교량받침으로부터 맞은편 교량상판(1) 단부 양측까지의 신축장이 서로 다른 경우, 동일교량 내에서 서로 다른 값의 신축량이 발생하게 되어 교량상판(1) 단부는 신축에 따른 평행이동을 하지 않고, 일정한 각도를 가진 부채꼴 모양으로 벌어지게 되는데, 이러한 경우 기존의 신축이음장치를 설치하기 위해서는 현황에 대한 상세한 분석이 필요하며, 기존 신축이음장치 단면형상 변경 등의 추가적인 조치 및 정밀시공 등이 요구되기도 한다.In addition, when the expansion joints from the fixed bridge support to the opposite ends of the bridge top plate (1) opposite to each other as in the case of sasho bridge or curved bridge bridge are different from each other, different values of expansion and contraction are generated in the same bridge, In this case, detailed analysis of the present situation is required to install the existing expansion joint device, and additional measures such as changing the shape of the existing expansion joint device and the like are required. Precision construction is also required.

기존 신축이음장치는 국부적이거나 전체적인 손상이 발생하면, 일정한 크기의 블록 전체를 교체해야하고, 보수교체를 위한 교통 통제 구간이 넓어지며, 보수교체를 위한 작업시간도 상당히 많이 소요되며 된다. 신축이음장치 보수교체시 교체블록의 무게도 인력으로 취급하기에 어렵고 보조장비의 추가투입이 필요하다.In the case of a conventional expansion joint, if a local or global damage occurs, the whole block of a certain size must be replaced, the traffic control section for repair replacement is widened, and the work time for repair replacement is considerably high. When replacing the maintenance of the expansion joint, the weight of the replacement block is difficult to handle as a manpower, and additional auxiliary equipment is required.

현재 사용되고 있는 대부분의 교량용 신축이음장치는 교축방향 신축만 수용하고 지진시 불규칙한 변위를 흡수할 수 있는 지진시 변위 흡수능력을 구비하지 못하고 있으며, 지진시 변위 흡수능력을 구비한 신축이음 장치의 경우도 구성 자체가 매우 복잡하고 설치도 어려운 문제점을 갖고 있다.Most of the currently used stretch joints for bridges do not have the capability of absorbing displacement during earthquakes that can only accommodate stretching in the thrashing direction and absorb irregular displacements during earthquakes. In the case of expansion joints equipped with displacement absorbing capability during earthquakes There is a problem that the configuration itself is very complicated and difficult to install.

이에, 본 발명은 상기와 같은 종래의 제반 문제점을 해소하기 위하여 안출된 것으로, 그 목적은 교량의 교축방향 변위 뿐만아니라 교축직각 방향 변위와 상,하 단차 변위도 흡수하고, 신축이음장치의 파손없이 교량상판(1)의 비틀림 거동까지도 수용하며, 지진시나 수평하중이 작용하는 경우에도 절개부에서 교량상판(1)의 연속성을 유지시켜 차량통행이 가능토록하는 지진시 변위 흡수능력을 갖춘 교량용 신축이음장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the related art as described above, and its object is to absorb not only displacement in the throttle direction of the bridge but also displacement in the direction perpendicular to the throttling axis and upper and lower step displacement, It is possible to extend the bridge top plate 1 in the incision to accommodate the torsional behavior of the bridge top plate 1 and to maintain the continuity of the bridge top plate 1 even in the event of an earthquake or a horizontal load, To provide a coupling device.

또한, 본 발명의 목적은 소규모 세트(SET)로 제작되면서도 구성이 단순하여 보수교체시 취급도 쉽고, 교체방법도 간단하여 교통통제 구간 및 시간을 최소화 해 줄 수 있는 교량용 신축이음 장치를 제공함에 있다.Also, the object of the present invention is to provide a flexible joint for a bridge that can be manufactured in a small set (SET), simple in construction, easy to handle in repair and replacement, and minimized in a traffic control section and time, have.

이상에서와 같이 본 발명은 종래의 장치에 비하여 다음과 같은 여러 가지 장점을 갖는다.As described above, the present invention has the following advantages over the conventional apparatus.

첫째, 교량상판(1)에 발생하는 교축방향 신축변위 뿐만아니라, 교축직각방향 수평변위와 지점침하 등에 의한 상,하 단차 변위도 수용할 수 있다.First, not only the expansion and contraction displacement in the thrashing direction generated in the bridge upper plate (1), but also the upper and lower step displacement due to lateral displacement and point settlement in the direction perpendicular to the throat axis can be accommodated.

둘째, 사교나 곡선교 단부에서 발생하는 온도신축이나 지진 등에 의한 불균등 변위도 수용할 수 있다.Second, unequal displacements due to temperature expansion and contraction caused by sagging or curved bridge ends can be accommodated.

세째, 일반적인 신축이음장치의 경우 직교에 적용하는 형식을 사교나 곡선교에 적용하기 위해서는 단면형상의 변경이나 특별한 고려가 필요하지만, 본 발명의 경우 기본단면형상의 변경없이 직교, 사교, 곡선교에 동일한 형상을 그대로 적용할 수 있다.Third, in the case of a general expansion joint device, it is necessary to change the cross-sectional shape or consider special consideration in order to apply the orthogonal type to the sagittal or curved bridge. However, in the present invention, the orthogonal, The same shape can be applied as it is.

네째, 일반적인 신축이음장치가 큰 블록 단위로 제작되어 설치시나 유지관리시 인력작업 및 취급이 어렵고, 추가적인 장비를 투입해야하는 등의 문제점이 있었으나, 본 발명의경우 작은 세트(SET)로 제작되고, 구성도 단순해서 인력작업이 간단하고 취급도 쉽다. Fourth, since a general expansion joint device is manufactured in a large block unit, it is difficult to work and handle manpower during installation or maintenance, and additional equipment must be input. In the case of the present invention, however, It is simple and easy to work with.

다섯째, 보수교체시 일반적인 신축이음의 경우, 교체시간이나 차량통제 등 간접비용의 손실이 크지만, 본 발명의 경우 교체시간도 짧고, 국부적으로 교체가 가능하여 경제적이다.
여섯째, 신축이음 각 연결부에는 수직력 및 수평력만 작용하고, 모멘트 및 인발력 등 다른 단면력은 작용하지 않으므로 구조계산이 간단하다.Fifth, in the case of a general expansion joint at the time of maintenance replacement, there is a large loss of indirect costs such as replacement time or vehicle control, but the replacement time is short in the present invention and it is economical because it can be locally replaced.
Sixth, the calculation of the structure is simple because only vertical force and horizontal force are applied to each joint of expansion joint and other force such as moment and pull force does not act.
