Description
Technical field
The utility model belongs to arch bridge suspender replacement apparatus field, and the prestressing force for being particularly used for arch bridge suspender replacement is spelled
Dress formula Hanging Basket.
Background technique
Since the nineties in last century, China has built a large amount of half through or through arch bridge, such bridge mainly passes through sunpender
The dead load of bridge deck and mobile load are transferred to arch rib, therefore sunpender is crucial supporting member.Old sunpender system used at that time
Substantially parallel steel wire+bulb-end anchorage mode.Due to by the factors shadow such as technical level at that time, quality of materials and construction quality
It rings, after bridge is completed more than 10 years, sunpender just starts disease occur, and the safety for being increasingly becoming bridge structure over time is hidden
Suffer from, or even Hangers failure occur to cause the event of bridge collapse.The service life of sunpender is generally 20 years, from the nineties in last century
Arch bridge is completed so far, will have a large amount of sunpender to reach its service life, needs replacing.
Currently, taking two ways, a kind of mode mostly for job platform below the bridge deck structure of arch bridge suspender replacement
To set up full framing mode from more than ground, disadvantage is long construction period, and costly, progress is slow, and it is big to set up work surface, work
Intensity is high.Another way is Hanging Basket mode under beam, and disadvantage is that monoblock type segment sizes are longer or wider, and inconvenience is carried, transported
And peace is torn open, need to frequently be cooperated using large-scale lifting appliance, is used in turn at high cost；It is elongated under beam in addition, the increase wide with bridge
The span of Hanging Basket increases therewith, middle span deflexion deformation it is larger, for increase construction its steel using amount of rigidity dramatically increase, cause manufacture,
Processing cost is high.How Hanging Basket lightness, peace are torn open and convenient transportation, manufacture processing and construction cost are reduced, convenient for standardization week
Turn to use, improves and use degree of safety, become letter problem to be solved.
