Description
Technical field
The utility model is related to bridge construction technical field of structures, in particular to a kind of cast-in-place simple supported box beam wheel-track type side form
Structure.
Background technology
In the construction of cast-in-place simple supported box beam, side form generally uses full framing or steel truss.Full framing is by three-dimensional foot
The compositions such as hand pipe, fastener, jacking, it is simple in structure, convenient to assemble and disassemble.Steel truss is by small-sized channel steel or I-steel combination junction steel plate
It is welded, intensity is higher, and globality is strong.But, quantities larger cast-in-place simple supported box beam construction more in face of quantity, the two are total
Same disadvantage is, without convenient mobile system, template turnover is inconvenient, and full framing needs dismounting completely, is transported to next Pin
It is set up again at box beam, steel truss needs to use large lifting equipment handling, and flat car is transported at next Pin box beams pacifies again
Dress, both needed large scale equipment to coordinate, and operating expenses is higher, and can not ensure cast-in-place simple supported box beam template construction work efficiency, and lifted by crane
Security risk is higher.
At present it has been suggested that setting can be along the formwork structure of bridge longitudinal movement, such as Patent No. " CN102140779A "
The Chinese invention patent of entitled " a kind of movable type cast-in-place support ", the patent describe a kind of cast-in-place support of Integral movable,
For pouring box-beam structure, entire formwork structure is slidably connected on crossbeam, and crossbeam is supported by pier stud, when a Pin box girder webs
After the completion, template is driven to longitudinally move to next Pin casting positions along bridge by the sliding system on crossbeam.This formwork structure
Although the difficulty of template movement can be reduced effectively, there are following inconvenience for it：(1) structure movement position be side form, bed die,
Distribution beam and longeron, moving structure is extremely huge, and construction is excessively complicated, and moving structure is excessively high, and construction safety risk is big；(2)
The structure slide device is plastic alloy plate, and since frictional resistance is larger, slide device need to use jack to coordinate steel strand wires, sliding
Shifting difficulty is big, and work efficiency is low；(3) the structure jacking system is jack, and descending operation difficulty is big, and since structure is higher, very heavy
It topples if top operates the slightly asynchronous whole system that would potentially result in；(4) side form itself is fixed with bed die on bridge longitudinal direction
, side form does not have the ability that fining is adjusted after entire formwork structure moves in place, cannot be carried out to side form position subtle
It adjusts, influences the effect that side form pours.
