Description
Technical field
The invention mainly relates to technical field of bridge engineering, more particularly to a kind of continuous beam closure box hat constructing device in place
And construction method.
Background technology
Current across railway line Construction of continuous beam is to avoid mostly becoming to both wired interference to using flat turn rotator construction
Gesture develops, but in the midspan closing stage, construction working face still exposed to both wired tops, is still had using the closure of conventional Hanging Basket
All multipair existing lines produce the unfavorable factor of harm.Therefore arisen at the historic moment using the form of construction work of overall box hat closure, its is main
Solution is prior across the curb girder each pre-buried one section of box hat in end in closure T structures, after the completion of T structures are turned, between two sections of pre-buried box hats
A part of gap is left, the portion gap is integrally transferred and closed by the later stage box hat that will join the two sections of a bridge, etc.The box hat that joins the two sections of a bridge, etc is advance system
The overall steel member of work, its size can fit by pre-buried box hat envelope and therewith just.But overall steel shell volume is huge, deadweight is normal
More than 3 tons are reached, high is required to the transhipment rigidity of structure, and can only the installation within the limited skylight period.Most of T structures
Do not possess the condition that bridge crane is filled on middle heavy-duty hoisting equipment after swivel still；And the outer large radius lifting operation of line equally exists many safety
Hidden danger；Conventional semi-artificial cooperation small machine transporting mode often shows to obtain inefficiency again, and past in the stage in place of joining the two sections of a bridge, etc
It is past to there is non-controllable risk source.
The content of the invention
