Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in figures 1 to 6, a kind of dislocation of concrete box girder high-altitude is cast-in-place with traversing supporting structure in place, in fig. 1 I,
II, III, IV box beam support position supporting structure, high-altitude dislocation cast-in-place support system, traversing strutting system in place is respectively represented and is showed
Stage span centre holder is poured, supporting structure includes high-altitude dislocation cast-in-place support system 1 and traversing strutting system in place 2, the high-altitude
Dislocation cast-in-place support system 1 is made of lower part beam-column type bracket and top high position full framing, the traversing strutting system 2 in place
For beam-column type bracket, top is provided with electronic trolley 13 and track 16, and by lateral Bailey beam 11 and its upper track 16 with
High-altitude dislocation cast-in-place support system 1 connect it is integral, it is described it is traversing refer to direction across bridge direction movement.
Beam-column type bracket in high-altitude dislocation cast-in-place support system 1 is by ground upwards successively including basis 4, steel pipe post
5a, lateral I-steel 6, longitudinal Bailey beam 7, using concrete continuous footing under column, 3 end bearing position steel pipe of box beam is vertical on basis 4
Column 5a is double, and lattice column is formed using the connection of vertically and horizontally bridging 8, and 7 both ends of longitudinal Bailey beam exceed box beam 2-4m, on
Portion is laid with the construction operation platform 9 of beam processed, and lower section steel pipe post 5b is single, is connected using lateral bridging 8.
10 pedestal of high-order full framing is longitudinal Bailey beam 7, and 3 end bearing position of box beam is supported using lateral Bailey beam 11,
11 top of lateral Bailey beam to 3 bed die of box beam is followed successively by sleeper 17, track 16, electronic trolley 13.
Traversing strutting system in place 2 includes basis 4, steel pipe post 5c, longitudinal I-steel 12, transverse direction successively upwards by ground
Bailey beam 11, sleeper 17, track 16, the basis of target position is preferentially using concrete continuous footing under column, when being overlapped with cushion cap 14
