E, installation i iron distribution beam
After sand cylinder installs, horizontal i iron distribution beam is installed at its top;
F, installation wedge
The stability of installing for strengthening Bailey beam, installs wedge at i iron distribution beam top, by shellfish thunder pin, it is connected on tapered plane with Bailey beam, is fixed;
G, segmented assembly standard Bailey beam
On smooth location, in advance standard Bailey beam is carried out to segmented assembly;
H, segmental hoisting Bailey beam
Intersegmental at longitudinal two adjacent supporting sections, lifting standard Bailey beam;
I, Bailey beam connect arching
After the installation of each sections standard Bailey beam, start to install being connected of Bailey beam one and bridge pier, and will between sections standard Bailey beam, connect into entirety by Bailey beam two, and make Bailey beam be assembled into multiple interconnective tapered planes, on each tapered plane, be provided with again arc support; On arc support, set up again casting template and become into arch structure.
Beneficial effect:
The utility model, mainly in high Loads of Long-span Bridges construction, while adopting Bailey beam support cast-in-place to execute, is set up in the situation that certain angle need to be set and is used when support;
Difficulty of construction is little, and construction technology is simple; Can first ground on the scene Bailey beam be carried out assembled, then install by hanging device; Between wedge and Bailey beam, only need to be connected, to fix by shellfish thunder pin; Easy to operate, safety factor is high; Construct at the scene in normal situation, lift one group of Bailey beam more 20 minutes, can save a large amount of durations; Because Bailey beam has good rigidity, laterally connect into the rear structural stability of entirety good, fitting operation safety factor is high.
The installation of stamping die sand cylinder is carried out trickle adjustment, is reached better bridge molding effect support post absolute altitude simultaneously.
Stamping die sand cylinder top is installed horizontal i iron distribution beam and has not only been solved installation and fine setting, and the use of distribution beam simultaneously makes its structure more firmly solid.
The use of voussoir one and voussoir two, convenient fine setting and dismounting.
In sum, the utility model, in high Loads of Long-span Bridges construction, has quite significantly advantage compared with prior art.
