With the example that is cast for of the bridge Standard Beam section that is connected and bridge widening beam section, the course of work of the wide curved bridge mobile formwork of the utility model luffing is as follows:
At first pour into a mould bridge Standard Beam section, to be installed on the good bridge pier 19 of cast such as Fig. 1, Fig. 3 and the wide curved bridge mobile formwork of this luffing shown in Figure 4, two interim girders 1 are set, girder 9 and interim girder 1 common supporting traverse 2 and outer modular system between two girders 9.Start hydraulic power unit 14, transverse shifting hydraulic cylinder 13 drives and advances flatcar 10 transverse shiftings, advances flatcar 10 to drive carriage 18, interim girder 1 and girder 9 transverse shiftings, thereby the bed die 5 of crossbeam 2 and outer modular system is closed up.Crossbeam 2 after will closing up and close up after bed die 5 usefulness bolts be linked as integral body, thereby realize the matched moulds of outer modular system.Adjust vertical mobile hydraulic cylinder 12, raise carriage 18, interim girder 1, girder 9, crossbeam 2 and outer modular system, carriage 18, interim girder 1, girder 9, crossbeam 2 and outer modular system are raised to the bridge casting position after, assembly unit internal mold 3 and internal mold support 4.Internal mold 3 and internal mold support 4 assembly units finish after, at internal mold 3 and finish between the outer modular system of matched moulds and build an amount of concrete, thereby finish building of bridge standard bridge section.
In conjunction with Fig. 2, through concrete curing and after reaching the stretch-draw requirement of strength, remove internal mold support 4 and internal mold 3, adjust vertical mobile hydraulic cylinder 12, thereby carriage 18, interim girder 1 and girder 9 are moved down, and carriage 18, interim girder 1 drives crossbeam 2 when moving down with girder 9 and outer modular system separates with in type pontic.After removing part crossbeam 2 and bed die 5, adjust transverse shifting hydraulic cylinder 13 and make propelling flatcar 10 transverse shiftings, advance flatcar 10 to drive carriages 18, interim girder 1 and girder 9 transverse shifting certain distances, thereby avoid interim girder 1 and girder 9 when vertical shift and bridge pier bumps.Fig. 2 be the utility model build bridge Standard Beam section finish and die sinking after the structural entity schematic diagram.
In conjunction with Fig. 2 and Fig. 5, after the moulding of bridge Standard Beam section, can descend the cast of two bridge beam widening beam sections.At first be arranged between interim girder 1 and the carriage 18 and between girder 9 and the carriage 18 vertically move hydraulic cylinder 15 drive interim girder 1, girder 9 and split after outer modular system vertically move, finish mobile formwork two and stride vertical shift.According to the Specific construction situation, for every girder 9 or interim girder 1, also can adjust simultaneously the transverse shifting hydraulic cylinder 13 of 10 in each bridge pier 19 place's bracket beam 11 and propelling flatcar, realize that carriage 18 is around vertical mobile hydraulic cylinder 12 deflections, carriage 18 drives girder 9 or interim girder 1 deflection of supporting, and makes things convenient for the luffing via hole.Because Bridge Beam section to be cast is widened, its bridge pier 19 central post quantity increase, corresponding bracket beam 11 needs to increase corresponding length, crossbeam 2 and bed die 5 also need increase respective width, do not changing in the integrally-built situation of mobile formwork, below bracket beam 11, increasing bracket column 20 according to the pier column quantity that increases and support so that the bracket beam 11 that lengthens is formed reliably; Two interim girders 1 of other increase between two girders 9 make the number of interim girder 1 increase to four with crossbeam 2 and reliably support of bed die 5 formation to widening, thus the construction quality of the moulding of the wide bridge of realization luffing and assurance different in width Bridge Beam section.Above-mentioned basis bridge width to be built is adjusted flexibly the job practices of interim girder 1 and bracket column 20 quantity and has been avoided integral replacing mobile formwork when building the wide bridge of luffing, has greatly improved efficiency of construction, has reduced cost.Adjust transverse shifting hydraulic cylinder 13, it is driven advance flatcar 10 transverse shiftings, advance flatcar 10 to drive carriage 18, interim girder 1 and girder 9 and move, realize the matched moulds of outer modular system.Adjust vertical mobile hydraulic cylinder 12, raise carriage 18, interim girder 1, girder 9, crossbeam 2 and outer modular system, carriage 18, interim girder 1, crossbeam 2, girder 9 and outer modular system are raised to the bridge casting position after, assembly unit internal mold 3 and internal mold support 4.Internal mold 3 and internal mold support 4 assembly units finish after, at internal mold 3 and finish between the outer modular system of matched moulds and build an amount of concrete, obtain the matched moulds state overall structure schematic diagram of the utility model cast bridge widening beam section as shown in Figure 5.
In conjunction with Fig. 6, through concrete curing and after reaching the stretch-draw requirement of strength, remove internal mold support 4 and internal mold 3, adjust vertical mobile hydraulic cylinder 12, thereby carriage 18, interim girder 1 and girder 9 are moved down, and carriage 18, interim girder 1 drives crossbeam 2 when moving down with girder 9 and outer modular system separates with in type pontic.After removing part crossbeam 2 and bed die 5, adjust transverse shifting hydraulic cylinder 13 and make propelling flatcar 10 transverse shiftings, advance flatcar 10 to drive carriage 18, interim girder 1 and girder 9 transverse shifting certain distances, thereby avoid interim girder 1 and girder 9 when vertical shift and bridge pier bumps, Fig. 6 be that the utility model builds that bridge widening beam section is finished and die sinking after the structural entity schematic diagram.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solutions of the utility model.
