After forming the shredding part 42 to expose the reinforcing bar, remove the welded bridge device and A first method for replacing a left device.

한편, 국내 특허등록 제0378382호에 따르면, 강계용 유압잭 하부 받침장치의 경우에는 교각의 일측 상면을 덮으면서 교각의 양쪽 둘레면에 커버링되는 채널형 브래킷 양측에 안착부가 형성된 것이 특징이며, 상부받침장치는 교량의 종류에 따라 달라지는데, 특히 교량이 콘크리트 교일 경우에는 거더가 피시빔으로 구성되는데, 피시빔에 구성된 통상의 가설공을 이용한 것으로, 피시빔 저면에 밀착되는 베이스플레이트의 양측 상면에 사이드 브래킷을 체결부재로 고정하되, 피시빔의 가설 공 대응 위치의 사이드 브래킷 상부에는 상기 가설공에 관통되는 강봉 양단에 캡이 삽입지지되는 결합공을 구비하는 제2방식이 있으며, 상기 제2방식에서 강봉의 양단은 나사부를 형성해 너트를 체결할 수도 있음이 시사된바 있다.Meanwhile, according to Korean Patent Registration No. 0378382, in the case of the hydraulic jack lower support device for steel type, seating parts are formed on both sides of the channel bracket covered on both circumferential surfaces of the piers while covering the upper surface of one side of the piers. Depends on the type of bridge. Especially, if the bridge is a concrete bridge, the girder is composed of fish beams, and it uses the usual construction holes for the fish beams, and the side brackets are attached to the upper surfaces of both sides of the base plate that are in close contact with the bottom of the fish beams. It is fixed by the fastening member, the second side of the upper side bracket at the position corresponding to the temporary ball of the fish beam has a coupling hole for inserting the cap is supported on both ends of the steel rod penetrating the temporary hole, the second method of the steel bar It has been suggested that both ends may form a threaded portion to tighten the nut.

한편,국내 특허등록 제0338490호에 따르면 교각의 상부에 상부구조의 길이방향으로 다수개의 종방향 사각관을 설치하고, 상기 교각의 상부면에 지지됨과 더불어 상기 지지부재에 의해 지지되도록 클립을 이용하여 교각의 폭에 맞춰 잭을 설치할수 있도록 된 잭 받침부재를 설치하여, 상기 잭받침부재에 의해 잭을 설치하여 상부구조를 인상하는 것을 특징으로 하는 것으로 한다.Meanwhile, according to Korean Patent Registration No. 0338490, a plurality of longitudinal square tubes are installed in the longitudinal direction of the superstructure on the upper part of the pier, and are supported on the upper surface of the pier and are supported by the support member. It is characterized in that to install a jack support member to be able to install the jack in accordance with the width of the piers, to install the jack by the jack support member to raise the upper structure.

상기와 같이, 교량 교좌장치 교체보수용 각 인상장치에 있어서 예상되는 문제점은 다음과 같다.As described above, the expected problem in each of the lifting device for the bridge bridge replacement device replacement is as follows.

즉, 상기 제1방식에서 잭받침부재(50)를 제거한 다음, 상기 파쇄부(42)와 교각 상부 측방에 각 천공시킨 앵커볼트공은 콘트리트 몰탈로 메꾸는 것으로, 교좌 교체공사가 끝난 후에 콘크리트타설부(43)와 앵커볼트공메꿈부(44)의 흔적이 남을 뿐만 아니라, 폭 2m의 교각(30) 양측에 각 깊이 20㎝의 앵커볼트구멍이 천공되기 때문에 교각(30)에 균열이 발생되어 내구성이 저하되는 문제점을 안고 있는 실정이다.That is, after removing the jack support member 50 in the first method, each of the anchor bolt ball perforated in the crushing portion 42 and the upper side of the pier to fill with concrete mortar, concrete placement after completion of the bridge replacement work Not only the traces of the part 43 and the anchor bolt hole 44 are left, but the anchor bolt holes having a depth of 20 cm are drilled on both sides of the pier 30 having a width of 2 m, so that cracks are generated in the pier 30. The situation has a problem that the durability is reduced.

또한, 상기의 제2방식에서는 콘크리트 교에 설치되는 인상장치중 특히 상부받침장치로 피시빔 양측방에 천공된 가설공에 끼운 강봉을 베이스플레이트 양측 상면에 구성한 사이드브래킷에 끼운 베이스플레이트 하방에 마련된 안착부와 교각상부에 설치한 하부받침장치의 안착부 사이에 유압잭을 설치한다고 하였으나, 수평으로 설치된 교각과 교각간에 설치된 피시빔을 인상하는 경우에 적용하는 실정이다.In addition, in the second method described above, the steel bar inserted in the temporary hole drilled on both sides of the fish beam by the upper support device among the lifting devices installed in the concrete bridge is provided below the base plate inserted in the side bracket formed on the upper surface of both sides of the base plate. It is said that the hydraulic jack is installed between the seat and the seating portion of the lower support device installed on the upper part of the pier, but the situation is applied when the fish beam is installed between the pier and the pier horizontally installed.

그러나, 사면으로 이루어진 교량의 교각 상부와 피시빔 저면부에 설치된 교좌장치가 안착된 사이는 매우 협소하여 상부받침장치와 하부받침장치로 이루어진 상기와 같은 인상장치는 사용할 수 없게 되는 문제점을 안고 있다.However, there is a problem that the above-mentioned lifting device composed of an upper supporter and a lower supporter cannot be used between the upper part of the pier of the bridge consisting of the slope and the seating device installed on the bottom portion of the fish beam.

그리고, 상기의 제3방식에서의 잭받침부재는 교각상부에 설치된 교좌장치 양옆으로 설치된 다수개의 지지부재에 클립을 이용하여 교각의 폭에 맞춰 잭을 설치 하도록 된 잭받침부재는 교좌장치에 안치된 피시빔 마다 1개씩의 유압잭을 설치함에 따라, 인상작업중 교량의 상부에 동 하중이 가해지는 경우 이를 수용하지 못해 비틀림 응력을 받아 좌굴, 변형 등이 발생하여 유압잭과 피시빔의 중심점이 어긋나 유압잭이 튕겨나가는 안전사고가 발생할 소지를 갖고 있다.And, the jack support member in the third method is a jack support member to install the jack in accordance with the width of the piers by using a clip on a plurality of support members installed on both sides of the bridge device installed on the pier is placed in the bridge device As one hydraulic jack is installed for each fish beam, if a dynamic load is applied to the upper part of the bridge during the lifting operation, it cannot be accommodated, and under the torsional stress, buckling and deformation occur, causing the center of the hydraulic jack and the fish beam to deviate and the hydraulic jack bounces. There is a risk of outgoing safety accidents.

또한, 사면을 이루어진 교량의 교각 상부에 양쪽으로 분할되어 거치된 2개의 피시빔 저면부 상기 교각상부의 사이는 매우 협소하다.Further, two fish beam bottom portions which are divided and mounted on both sides of the pier upper part of the bridge having a slope are very narrow between the upper part of the pier.

때문에,상기 제3방식에 의하여 제안된 바와 같이, 길이방향으로 설치되는 종방향 사각관을 끼울 수 없는 경우에는 상기 지지부재에 클립으로 조립하는 잭받침부재를 설치하지 못하는 예가 많을 것으로 예견된다.Therefore, as suggested by the third method, when it is not possible to insert the longitudinal square tube installed in the longitudinal direction, it is expected that many examples that the jack support member to be assembled by the clip to the support member can not be installed.

이에 본 발명에서는 종래 교각 상부면과 피시빔 저면부의 공간이 협소하여 유압잭을 설치하지 못하는 사면을 이루는 교량의 경우에는 교각상부에 안착된 피시빔을 인상시키는 위한 장치로는 교각의 상부면 폭방향 양편에 안착된 교좌장치(40)에 안착된 피시빔의 저부면중 교좌장치 외측편을 커버링하는 피시빔 폭 규격의 하판(110)과;Accordingly, in the present invention, in the case of a bridge that forms a slope where the space of the upper portion of the pier and the bottom portion of the fish beam is narrow, and the hydraulic jack cannot be installed, the device for raising the fish beam seated on the upper portion of the pier is wide in both directions in the upper surface of the pier.
