Continuous the problem of retreating, and then provide a kind of auxiliary mobile formwork girder suspention retrogressing construction party suitable for variable cross-section beam section
Method.
The present invention adopts the following technical scheme that：
A kind of auxiliary mobile formwork girder suspention suitable for variable cross-section beam section retreats construction method, utilizes simple crossbeam and movement
The rear cross beam of mould bases is attached, and by the girder of simple crossbeam and mobile formwork connect, then by operate mobile formwork after
Longitudinal thrustor of crossbeam retreats to drive mobile formwork girder to realize continuously.
The simple crossbeam has poured the top of box beam across the rear cross beam setting for having poured box beam, being parallel to mobile formwork
Face is equipped with several dragging tracks along longitudinal direction, and simple crossbeam bottom is connected and can freely be slid along dragging track with dragging track
Walking, the both ends of simple crossbeam are symmetrically installed with two groups of hoist engines, two groups of hoist engines respectively by fixed pulley group, steel wire rope with it is right
The mobile formwork girder of side is answered to connect.
The simple crossbeam includes shellfish thunder crossbeam and Bei Leizhu, shellfish thunder crossbeam be parallel to mobile formwork rear cross beam setting,
Shellfish thunder crossbeam both ends are cantilevered out have been poured outside box beam both sides, two groups of shellfish thunder columns be symmetrically connected to by U-bolt shellfish thunder below the crossbeam,
Whole is in " π " type structure, and the bottom of Bei Leizhu is correspondingly provided with several traveling wheels along dragging track sliding walking, shellfish thunder crossbeam
Both ends top surface is equipped with hoist engine mounting platform, and hoist engine is installed on hoist engine mounting platform.
The dragging track being arranged below every group of shellfish thunder column is no less than four, and four dragging tracks are mutually parallel, set at equal intervals
It sets, the traveling wheel corresponding matching of the column bottoms Bei Lei walks in each dragging track.Because the overall width of dragging track is shellfish thunder
The support width of column then needs the bearing capacity and operation stability that consider Bei Leizhu, for the width of general Continuous Bridge, work
The quantity of word steel dragging track should not be less than 4.
The dragging track has several I-steel, and longitudinally spelling is taken, and the lumps of wood is equipped in the bottom plate rabbet of I-steel.
The hoist engine mounting platform is installed on Bei Lei by several connection I-steel and the laterally adjustable formula of fining twisted steel
On crossbeam, by structure adjusting both sides dragging track, the mounting distance of both sides shellfish thunder column and two groups of hoist engines in moving process,
It can adaptively realize the continuous retrogressing of mobile formwork girder.
The present invention be by assembled simple crossbeam, installation electrical hoist, fixed pulley group construction method, movement can be made
Mould bases is fallen back safely, efficiently solves the problems, such as that mobile formwork cannot transfer in situ, and safe efficient rate is completed under mobile formwork
Put construction；Meanwhile the width distance by adjusting two groups of hoist engines, dragging track and the positions shellfish Lei Zhu, it can self-adapting variable cross-section
The continuous retrogressing of beam section, and then shorten mobile formwork and retreat construction period, mechanical equipment input is reduced, operating expenses, drop are saved
Low construction safety risk.
