Description
Technical field
The utility model belongs to technical field of bridge construction, especially relates to the dismounting of a kind of downward mobile formwork bridge fabrication machine and uses overall lowering system.
Background technology
How safe mobile formwork bridge fabrication machine (abbreviation mobile formwork) is the sophisticated equipment of the large-scale beam of cast-in-situ, but its physical dimension, member dead weight are large, after beam processed completes, unload that to fall be a critical process.When the large-span continuous box beam up to tens of meters being constructed as adopted large bridge equipment MZ32 mobile formwork bridge fabrication machine, this mobile formwork bridge fabrication machine is primarily of part compositions such as front and back door frame, template system, girder, chassis, pier-side bracket, column and electric hydraulic systems and its gross weight is about 542t, wherein external mold and strut heavily about 90t, nose girder is 24t heavily about, girder is 148t heavily about, comb shape beam and dodge gate heavily about 77.2t, pier-side bracket is 60.4t heavily about, supporting station car weight is about 18.6t, front door frame assembly heavily about 11t, rear door frame assembly heavily about 16t, column is 70t heavily about.After having built concrete box girder, downward mobile formwork bridge fabrication machine is in the below of concrete box girder, and bridge pier is up to tens of rice, is unfavorable for the dismounting of single-piece.And the heavy difficult point that mobile formwork bridge fabrication machine is removed is the dismounting of girder, girder list vice president weight reaches 74t, and can girder unload safely that to fall to landing be the key of Dismantling of Movable Shuttering Form.Because beam body frange plate blocks, large-scale crane is utilized to remove difficulty.
Nowadays, when downward mobile formwork bridge fabrication machine is dismantled, mainly contain following two kinds of methods: the first adopts mobile formwork to retreat high-altitude disintegration dismounting method: the method can be used for having front and back nose girder and can carry out the mobile formwork that moves forward and backward, the mobile formwork cost of this type will exceed more than 200 ten thousand yuan, and the security risk that the existence of large-scale structure is dismembered in high-altitude is large, operation is loaded down with trivial details, and relevant supporting facility equipment is many; Second method removes nose girder and template system in advance, and the method is broken from case top surface of the beam, but built because of case beam, and mobile formwork bridge fabrication machine removes difficulty from case top surface of the beam; In addition, during blocked breaking removing template, template framework is transferred from bottom surface one by one, this needs reserved comparatively porous on case beam, and working space after the demoulding between mobile formwork bridge fabrication machine and case beam is little, and the resource of implementing to consume is many, cycle is long, security risk and cost higher, operate also very difficult.
Due in mobile formwork bridge fabrication machine demolishing process, the dismounting of nose girder is comparatively simple, thus after mobile formwork has built concrete box girder, if first remove nose girder, the mobile formwork after dismounting nose girder is dropped to ground and disintegrates by recycling lowering system, then significantly can reduce the dismounting difficulty of downward mobile formwork bridge fabrication machine, it is convenient to realize, the dismounting cycle is short, and security risk is little, and input cost is lower.
