Abstract

목적purpose

교량의 거어더 가설에 있어서, 지리적 조건등의 이유에 의하여 하천부지 및 유수부에 가설라인에 따른 거어더의 이동용 통로를 설치할 수 없는 경우에, 가설필 기설 거어더에 따라 이동하는 운반대차에 의하여 신설 거어더를 가설 필 선두 기설 거어더의 바로 아래까지 이송한 후, 이 신설거어더를 가설 필 선두 기설 거어더의 선단에 접속할 수 있는 가설공급을 제공한다.In the girder construction of the bridge, if the passage for moving the girder along the construction line cannot be installed in the river site and the flowing water due to the geographic conditions, etc., the transport cart moves along the temporary girder. After the new girder is transferred to the bottom of the temporary girder, the new girder is provided with a temporary supply for connecting the new girder to the leading end of the temporary girder.

구성Configuration

가설중의 선두 기설 거어더(3a)상에 선단(16)이 해당 선두 기설 거어더(3a)보다도 전방으로 돌출하는 가설용 데릭(7)을 배치하고, 신설거어더(6)를, 가설필기설 거어더(3)에 따라 이동하는 운반대차(5)의 운반와이어(9)에 의하여 선두 기설 거어더(3a)의 바로위까지 매달아 내려 이동한 후, 가설용데릭(7)의 선단에서 매달아 내린 이설와이어(17)의 하단을 신설 거어더(6)의 상면에 접속하고 상기 운반와이어(9) 그렇지 않으면 이설와이어(17)의 어느 한쪽의 와이어의 길이를 조절하여, 해당 전후 위치의 양와이어에 의한 거어더의 매달아 내림하중을 옮겨 바꾸는 것으로, 신설거어더(6)를 상기 선두 기설거어더(3a)보다도 전방의 가설지점 바로 아래로 이동한다.On the leading existing girder 3a under construction, the tip 16 projects a temporary derrick 7 that projects forward than the leading existing girder 3a, and puts the new girder 6 on a temporary basis. It hangs down to the top of the leading existing girder 3a by the transport wire 9 of the transport trolley 5 moving along the girder 3, and then hung from the tip of the temporary derrick 7 The lower end of the relocated wire 17 is connected to the upper surface of the newly formed girder 6, and the length of one of the wires of the carrying wire 9 or the relocated wire 17 is adjusted, so that both wires in the corresponding front and rear positions are adjusted. The new girder 6 is moved directly below the construction point ahead of the first existing girder 3a by changing the hanging load of the girder.

Claims

In the existing girder under construction, the leading end girder is fixedly placed on the leading girder, and the new girder to be installed is moved according to the existing girder. It is hung by the transport wire of the transport trolley, moved to just under the leading existing girder at the construction point, and the lower end of the relocation wire hung from the tip of the construction derrick is connected to the upper surface of the new girder, If the carrying wire is otherwise, the length of one of the moving wires is adjusted to change the hanging load of the girder by the two wires in the front and rear positions, and the new girder is placed at the front of the leading girder. Go right below, and in this state, erect the new girder upwards Girders of the bridge hypothesis method comprising connecting more.

The new girder, which is hung on the transport wire of the transport trolley and moved to just below the leading existing girder, is connected to the lower end of the predetermined length of the relocation wire hung from the tip of the temporary derrick, By winding up the length of the carrying wire, by changing the load of the new girder to the relocation wire, the new girder is shifted just below the construction point of the front, and the new girder is suspended upwards Girder construction method of bridge.

3. The lower end of the predetermined length of relocation wire hung from the end of the temporary derrick to the new girder, which is hung on the transport wire of the transport cart and moved to just below the leading girder. At the same time as connecting the new girder by pulling the new girder to the rear with a saving wire at the rear of the construction point, and winding the length of the carrying wire, changing the load of the new girder to the new reed wire and hanging the new girder A girder construction method for bridges, characterized in that the new girder is suspended upwards by moving it just below the temporary construction point in front of it.

The new girder, which is suspended from the transport wire of the transport cart and moves to just below the leading existing girder, continues the lower end of the relocation wire hung from the tip of the temporary derrick. Girder hypothesis of bridge, characterized in that the new girder is lifted up and down by changing the new girder just below the construction point of the front while changing the load of the new girder to the relocation wire. Method.

5. The transfer wire according to any one of claims 1 to 4, wherein the carrying wire is otherwise changed by changing the hanging load of the girder by both wires in the front and rear positions by adjusting the length of one of the wires of the moving wire. After moving the girder just below the construction point than the first girder, the new girder is hung upwards by the hanging cable of the tip of the construction derrick and connected to the existing girder. Girder construction method.
