본 발명은 현장에 구축되는 지지대상에서 교량상판을 거푸집을 이용하여 제작한후 제작된 교량상판을 직접 밀어내기식으로 교각상부에 이동시켜 교량을 설치할 때 사용하게 되는 레일 승강조절수단이 구비된 교량상판의 지지장치에 관한 것이다.The present invention is a bridge provided with a rail lifting control means that is used to install the bridge by moving the top of the bridge by direct extrusion method after the bridge top plate is manufactured by using the formwork in the support object to be built on the site It relates to a support device for the top plate.

일반적으로 현장에 구축되는 지지대상에서 거푸집을 이용하여 제작된 교량상판을 직접 교각상에 밀어내기식으로 이동하여 교량을 설치하는 교량의 시공방법에 사용되는 교량상판의 지지대는 도 1의 예시와 같이 교량 끝단의 교각가까운 지반에 콘크리트좌대의 레일지주로 구성된 주조물을 구축하고, 그 레일지주 상부에 레일을 설치하고 있고, 그 사용방법은 지지대의 레일 상부에서 거푸집을 이용하여 단위체 교량상판을 제작한 다음 제작된 위치에서 압출장치를 이용하여 교각상부로 이동시키는 과정을 반복하여 교량을 설치하고 있다.In general, the support of the bridge deck used in the construction method of the bridge to install the bridge by moving the bridge deck manufactured by using the formwork directly on the bridge in the field to be built on the site as shown in Figure 1 A casting made of rail supports of a concrete seat is constructed on the ground near the pier at the end of the bridge, and a rail is installed on the upper rail support. The method of use is to form a unit bridge deck using formwork on the upper rail of the support. The bridge is installed by repeating the process of moving to the upper part of the pier by using an extrusion apparatus at the manufactured position.

이때 지지대는 레일과 교각상단이 적정레벨을 유지하도록 설계되어 구축되는데, 그 지지대가 지반이 견고한 곳에 설치된 경우는 교량상판을 교각상부로 이동시키는 작업을 공사기간 동안 지속적으로 작업할 수 있으나, 지지대가 연약지반에 설치된 경우는 지반침하로 인하여 버팀대가 기울어 교각상단과의 적정레벨이 유지되지 못하면 교량상판의 이동작업이 불가능하게 된다. At this time, the support is designed and constructed so that the rail and the top of the bridge maintain the proper level. If the support is installed in a solid ground, the work of moving the bridge deck to the top of the bridge can be continued during the construction period. In the case of installation on the soft ground, it is impossible to move the bridge deck if the props are tilted due to ground subsidence and the proper level with the top of the bridge is not maintained.

이러한 경우는 부득이 레일을 철거하고 교각상단과의 레벨에 맞게 레일을 재 설치하여야 하는 문제가 있었고, 특히, 지지대상에 교량상판이 제작되어 있는 상태에서 지지대의 레일과 교각상단과의 적정레벨에 차이가 발생하면 이를 보정할 수 없어 교량상판의 이동작업을 할 수 없는 중대한 문제점이 있었다.In this case, the rail had to be removed and the rail had to be re-installed according to the level of the top of the pier. In particular, in the state in which the bridge deck was made on the support object, there was a difference in the proper level between the rail of the support and the top of the pier. There was a serious problem that can not be corrected when the movement of the bridge deck can not be corrected.

본 발명에서는 이상과 같은 종래의 문제점을 해결하기위하여 지지대에 레일을 설치하되, 레일지주 상면과 레일과의 사이에 레일승강조절수단을 설치함으로서 교량상판 지지대가 지반침하로 인하여 교량상판 지지대가 기울었을 때 교각과의 기울기를 적정레벨로 보정할 수 있게되어 교량상판의 이동설치작업을 수행할 수 있는 교량상판의 지지장치를 제공하게된 것이다.
In the present invention, in order to solve the conventional problems as described above, the rail is installed on the support, by installing the rail lifting control means between the rail support upper surface and the rail, the bridge deck support is tilted due to the ground subsidence When the slope with the bridge can be corrected to the appropriate level is to provide a support device for the bridge deck to perform the mobile installation work of the bridge deck.

이상과 같은 본 발명을 첨부도면에 따라 그 구성 및 작용을 상세히 설명하면 다음과 같다.Referring to the configuration and operation of the present invention as described above in detail as follows.

본 발명은 도 2의 예시와 같이 지반에 구축되는 콘크리트좌대(110)와 레일지주(120)로 구성된 지지대(100)를 구성함에 있어서, 상기 레일지주(120)에 레일(200)을 설치하되, 상기 레일지주(120)과 레일(200)과의 사이에는 잭(jack)과 같이 길이가 신축되는 레일승강조절수단(300)을 개입시켜 설치하여 레일의 높이를 조절할수 있게함을 특징으로 한 것이다.In the present invention to configure the support 100 consisting of a concrete seat 110 and the rail support 120 to be built on the ground as shown in Figure 2, the rail 200 is installed on the rail support 120, Between the rail support 120 and the rail 200 is installed through the rail lifting adjustment means 300, the length is stretched like a jack (jack) characterized in that to adjust the height of the rail .

본 발명실시에 있어서, 레일승강조절수단(300)은 고정좌대(310)와 가동좌대 (320) 및 승강용축(330)으로 구성되는 각종 잭(jack)을 사용할 수 있다. In the practice of the present invention, the rail lifting adjustment means 300 may use a variety of jacks consisting of a fixed seat 310, a movable seat 320 and a lifting shaft 330.

예를들면, 도 3의 예시와 같이 고정좌대(310)와 가동좌대(320)를 레일지주 (120) 상면과 레일(200) 저면에 각각 고정시켜 승강용축(330)의 회동손잡이(331)를 회동시 가동좌대(320) 쪽이 승강하여 레일(200)의 높이를 조절할 수 있게 한 스크류잭을 사용하거나, 도시하지 아니한 유압잭등을 사용할 수 있다.For example, as shown in FIG. 3, the fixed seat 310 and the movable seat 320 are fixed to the upper surface of the rail support 120 and the bottom of the rail 200, respectively, to rotate the pivoting knob 331 of the lifting shaft 330. At the time of rotation, the movable seat 320 may be elevated to use a screw jack to adjust the height of the rail 200, or a hydraulic jack not shown.

본 발명의 사용은 종래와 같이 레일(200) 상부에 거푸집을 이용하여 교량상판(400)을 제작한 다음 압출장치(500)로 상기 제작된 교량상판(400)을 도 4와 같이 교각(600) 상부로 이동설치하되, 이동작업을 실시하기 전에 레일(200)과 교각상단과의 적정레벨을 점검한다.The use of the present invention is to manufacture the bridge top plate 400 using the formwork on the rail 200 as in the prior art, and then the bridge top plate 400 produced by the extrusion device 500 as shown in Figure 4 bridge 600 Move to the upper installation, but check the appropriate level between the rail 200 and the top of the bridge before moving.

이때 오차가 있을 경우는 승강용축(330)을 승강시켜 레일(200)과 교각상단과의 오차를 보정한 다음 교량상판(400)의 이동작업을 실시하게 된다.In this case, if there is an error, the lifting shaft 330 is elevated to correct an error between the rail 200 and the upper end of the bridge, and then the bridge work plate 400 is moved.

이상과 같이 사용되는 본 발명 교량상판의 버팀장치는 버팀대(100)의 레일지주(120) 상면과 레일(200)과의 사이에는 길이가 신축되는 레일승강조절수단(300)을 설치하여 레일의 높이를 조절할수 있게한 것이어서 교량상판의 제작시에는 그 제작전에 레일의 수평을 조절하고, 그 위에 종래의 거푸집제조방법으로 교량상판을 제작하기 때문에 제작된 교량상판은 양생도중 레일상에서 하중이 편중되지 않아 비틀림현상이 일어나거나 편중에 의한 파손이 일어나지 않게 제작할 수 있는 효과가 있고, 양생도중 지반침하 또는 지각변동 등으로 지지대가 기울어 레일(200)과 교각상 단과의 적정레벨에 오차가 발생하면 레일하부의 레일승강조절수단(300)을 선택적으로 동작시켜 오차를 보정하여 교량상판의 이동설치작업을 수행 할 수 있는 효과가 있다.The support device of the bridge top plate of the present invention used as described above is installed between the upper surface of the rail support 120 of the brace 100 and the rail 200, the rail lifting adjustment means 300 is stretched to the height of the rail In the manufacture of bridge decks, the level of the rail is adjusted prior to its manufacture, and the bridge decks are manufactured by the conventional formwork manufacturing method.The bridge decks produced are not biased on the rails during curing. There is an effect that can be produced so that no torsional phenomenon or breakage due to bias occurs, and if the support is inclined due to ground subsidence or tectonic change during curing, an error occurs at the proper level between the rail 200 and the piers. By selectively operating the rail lifting control means 300 to correct the error there is an effect that can be carried out moving installation work of the bridge deck.
