Description
Technical field
The utility model belongs to field of bridge construction, is applicable in the constructions such as arch bridge dismounting.
Background technique
20th century of China build bridge because operation the age it is longer, occur old unsafe bridge in various degree, some because traffic be saturated,
Navigation capacity is promoted, and bridge is unsatisfactory for requirement, and more and more bridges need to be removed in situ carries out reorganization and expansion construction.Bowstring arch bridge
Because combining arch bridge and beam bridge advantage, last century is widely adopted.Because bowstring arch bridge is statically indeterminate system, Normal practice, tied arch
Bridge first sets up bracket, support tie bar and arch rib when removing in river, and then segmentation carries out arch rib dismounting.
It being continued to develop and is promoted by Navigation in Navigable, most of navigable river, which does not allow to carry out iceound or navigation hole width, to be reduced,
Cause part bowstring arch bridge that can not carry out bracket support when removing.
Utility model content
The purpose of this utility model is that: it proposes that a kind of shellfish thunder removed for bowstring arch bridge is counter and hangs combination boom device, energy
Enough when bowstring arch bridge need to remove progress reorganization and expansion construction in situ, realize arch bridge without support removing.
The utility model aim is realized by following technical proposals:
A kind of shellfish thunder removed for bowstring arch bridge is counter to hang combination boom device, if including newly building bridge and dried scallop thunder is counter lifts
It sets, newly building bridge is arranged side by side by old bowstring arch bridge to be removed, if the anti-device for hoisting of dried scallop thunder is across newly building bridge and to be removed
Old bowstring arch bridge connects two bridges, and for each anti-device for hoisting of shellfish thunder along bridge is indulged to parallel interval setting, each anti-device for hoisting of shellfish thunder includes one
Bailey beam, and three groups of anti-device for hoisting in Bailey beam, three groups of anti-device for hoisting are respectively to connect Bailey beam and newly building bridge
Outside binder one group of anti-device for hoisting, connect Bailey beam and old two binder of bowstring arch bridge to be removed two groups of anti-device for hoisting, respectively
Anti- device for hoisting includes finish rolling screw thread sunpender, upper supporting beam and lower supporting beam, and upper supporting beam is set to Bailey beam top surface, lower supporting beam
Set on binder bottom surface, finish rolling screw thread sunpender connects upper supporting beam and lower supporting beam.
Alternatively, be additionally provided with midfoot support beam between Bailey beam and two binders of newly building bridge, Bailey beam with it is to be removed
There are gaps between old two binder of bowstring arch bridge.
The aforementioned main scheme of the utility model and its each further selection scheme can be freely combined to form multiple schemes,
It can be used for the utility model and claimed scheme；And the utility model, (each non conflicting selection) selection between and and
It can also be freely combined between other selections.Those skilled in the art after understanding the utility model according to the prior art and
Common knowledge can be illustrated there are many combination, be the claimed technical solution of the utility model, do not do exhaustion herein.
The course of work are as follows: the shellfish thunder removed for bowstring arch bridge of the utility model is counter to hang combination boom device, and the device is suitable
It should construct in reorganization and expansion, newly building bridge can be relied on to carry out removal of old bridge by the device.When arch bridge segmentation is removed, binder and arch rib
Can not be individually from the device surely, can be set up on newly building bridge, which supports arch bridge binder, and then first arch is removed in segmentation
Rib, then binder is removed, realize arch bridge without support removing.
When old bridge concrete arch arch rib is removed, the self weight of arch bridge binder part is transferred to beam end support by self structure, remaining
Upper support that weight transmitting is to utility model device, route are as follows: is self-possessed binder part → lower supporting beam → finish rolling screw thread sunpender →
Beam → Bailey beam → newly building bridge realizes old bridge without support removing.
The utility model has the beneficial effects that the Support Method dismounting technique that the device is more traditional, is carried out old using newly building bridge
Bridge supports when removing, and effectively prevents setting up bracket within the scope of navigable, and avoiding, which influences navigation channel, normally opens the navigation or air flight, save the cost,
It is convenient to improve construction efficiency, constructing operation.
