Description
Technical field
It the utility model is related to a kind of cradle structure, the Hanging Basket in particularly a kind of reinforced concrete arch bridge building course
Structure.
Background technology
Since cast-in-place cantilever method is used in Arch Bridge Construction, successively there is positive triangle rod member in suspended casting suspended basket structure type
Formula Hanging Basket, inverted triangle rod member formula Hanging Basket, both Hanging Baskets achieve success on type of service, but with cantilever pouring length
And corresponding drawback also occur in the increasing of weight, both the above Hanging Basket, such as rod member stress is bigger than normal, the excessive feelings of cantilever end downwarp
Condition so that existing Types of Cradles can not meet the requirement of cantilever pouring.
Hanging Basket, which pours, to be completed because arch ring Hanging Basket is inclined, conducting oneself with dignity, it is necessary to Hanging Basket is moved forward behind a section
Under power effect, there is the trend slid backward, to move after avoiding Hanging Basket, generally open up aperture in the arch box bottom poured, insertion
Shaped steel, form stopping mechanism.But this mode has a problem that that is, port size is larger, reserve when cage bar avoid aperture,
Situations such as rear benefit concrete of orifice position can not completely be combined with original structure, cause arch ring force structure can not be kissed with original design
Close, bridge performance is impacted.
Furthermore due to not effective anti-offset structure in existing cradle structure movement forward, before causing Hanging Basket
Hanging Basket axis and arch ring axis not parallel situation occur during shifting so that horizontal drift condition occurs in Hanging Basket, and bridge needs
To be constructed according to design drawing, it is time-consuming and take so that need to carry out its horizontal skew error correction after hanging basket advancing
Power.
