At present, the mode arranging Zhongting in building is more and more general, the roof beam plated constructions such as such as, escalator in market.This structure carries out formwork as adopted traditional full hall console mode scaffold, not only sets up process comparatively complicated, particularly when beam and slab structure span is larger, time-consumingly especially takes material, and there is great potential safety hazard in work progress.At this moment be badly in need of a kind of safe and reliable formwork system and solve this problem, and Bailey bracket is as a kind of bottom support extensive use of support for shuttering, but for large span building construction, Bailey bracket is but subject to the lifting power of tower crane and many restrictions such as complete deck of having constructed when removing, and causes to remove Bailey bracket safely and effectively.
Utility model content
The purpose of this utility model is to provide a kind of dismounting system of large span building construction Bailey bracket, solve for large span building construction, Bailey bracket is subject to the lifting power of tower crane and the restriction of complete deck of having constructed when removing, and makes Bailey bracket cannot the technical problem of safe and effective dismounting.
For achieving the above object, the utility model adopts following technical scheme:
A kind of dismounting system of large span building construction Bailey bracket, comprise deck, draw-gear and slip steel pipe, the two ends, left and right of Bailey bracket to be removed are propped up respectively and are located on the deck of both sides, described dismounting system also comprises being arranged on shelves beam between structure on two sides layer, Bailey bracket to be removed is the first beret truss group and second beret truss group two parts shelving beam punishment, slip steel pipe is provided with between described first beret truss group and the deck in left side, described draw-gear be positioned at left side deck on and fix with the left part of the first beret truss group, make the first beret truss group under the effect of draw-gear on the deck in left side relative sliding, the right part of described second beret truss group has additional some splicing beret truss identical with Bailey bracket model, the number that splicing beret truss increases is to ensure that the beret truss number be shelved on the deck on right side is as the criterion than the many a slice of the unsettled number outside the deck on right side of the second beret truss group.
Described deck comprise structural column composition post net, set up at the online structure girder of post and structure secondary beam, the two ends of shelving beam to be set up on structural column and parallel with structure girder.
Described beam of shelving at least arranges one at interval of 9000mm along post net.
Described shelving between beam and Bailey bracket is provided with chock.
Described draw-gear is fixedly connected with structural column.
Compared with prior art the utility model has following characteristics and beneficial effect:
The bracing frame that the utility model adopts Bailey bracket and steel pipe frame to combine, structure shelves beam for newly-increased one, the calculating arrangement of reinforcement of this beam must through design accounting, beam disconnects Bailey truss and form beret truss group shelving, beret truss is spliced respectively in the end of beret truss group again, to ensure the many a slices compared with the beret truss of overhanging portion of the beret truss on structural plane, use in Chain block traction beret truss group to floor and remove, practical and convenient.Shelve the structure that completes when beam is construction in early stage, the overall reduction of erection time, save manpower, the very big hazards reducing dismounting, operative is safe and reliable and reduce construction cost.
The utility model can be widely used in the dismounting of large span Bailey bracket in Zhongting top structure form work engineering.
