It is linked to be one by the welding of gooseneck 12, temporary support bracing means 13 and steel anchor box 10 every longitudinal Wavelike steel webplate 16 of arrangement
Individual entirety, wherein, the top flange of each piece of Wavelike steel webplate 16 is disposed with two suspension centres 11 and lifts for loop wheel machine system, and corresponding
Weld at 11 position of suspension centre for lifting by crane the interim otic placode for connecting, it is horizontal with steel that one of suspension centre 11 is located at Wavelike steel webplate 16
The junction of beam 12, another suspension centre 11 are located at the junction of Wavelike steel webplate 16 and temporary support bracing means 13；And per block
11 position of suspension centre on Wavelike steel webplate 16 arranges identical；
（2）At the same time, on the N-1 Wavelike steel webplates sections 4 of Prestressed Concrete Box-Girder Bridges with Corrugated Steel Webs assembled Hanging Basket and before
Move, if Hanging Basket is made up of dry tablet main couple 1, horizontal-associate 3 and loop wheel machine system, spaced apart each longitudinal main couple along direction across bridge
1 connects and composes Hanging Basket entirety by horizontal-associate 3, and each correspondence of main couple 1 is arranged in each ripple in N-1 Wavelike steel webplates sections 4
Directly over shape steel web, and it is anchored on the box beam top board 9 on N-1 Wavelike steel webplates sections 4 by bearing pin 14；Wherein, respectively
Piece main couple 1 is spliced to form inclined parallelogram like by two triangular trusses, i.e. one of triangular truss anchor
It is fixed on top board 9, another triangular truss protrudes from the leading section of N-1 Wavelike steel webplates sections 4 to constitute loop wheel machine system
Mounting platform；
Aforesaid loop wheel machine system is installed on the top that Hanging Basket protrudes from 4 part of N-1 Wavelike steel webplates sections, including two
Symmetrically arranged crane 2, is placed with about 2 for lifting by crane the wirerope 15 for lifting, 15 lower end of the wirerope correspondence of every crane 2 in crane
The distribution beam 5 of one direction across bridge arrangement is hung with, if the lower flange Jing bolt connections of each road distribution beam 5 have arterial highway spaced apart
Vertical bridge is to shoulder pole girder 6；Wherein, distribution beam 5 is steel construction, is formed by the welding edge of a wing and ribbed stiffener on one block of steel plate；It is flat
Spreader beam 6 is then steel I-beam, and ribbed stiffener is welded on steel I-beam；
It should be noted that the center of gravity of each road distribution beam 5 is in the center of gravity of N Wavelike steel webplates sections 8 to be lifted
In same perpendicular, to guarantee that lifting is steady；Additionally, the position of each road shoulder pole girder 6 corresponds to be lifted No. N in lower section
16 position of each Wavelike steel webplate in Wavelike steel webplate sections 8, so that each road shoulder pole girder 6 can be with each Wavelike steel webplate when the time comes
16 correspondingly can connect, and the stress point of N Wavelike steel webplates sections 8 is respectively positioned on Wavelike steel webplate position, it is to avoid to be hung at
Malformation when at other positions；
