Description
Technical field
The present invention relates to a kind of bridge using Z bar plate connector to spell wide construction and its construction method.
Background technology
In recent years, with China's rapid development of economy, China's communication has significant progress.But due to
Personnel and goods and materials flowing are increasingly frequent, cause the surge of transport need.In order to meet the demand of the growing volume of traffic, when
It is preceding mainly to have two kinds of settling modes：First, build new line；Second, the original circuit of widening and rebuilding.Due to building new line expense
Height, long construction period, and traffic is blocked, therefore there is an urgent need to carry out reorganization and expansion to these highways, spelled by original Four-Lane Road
Width is six-lane or eight tracks, improves its traffic capacity.Bridge occupies larger specific gravity in highroad, spells width plus bridge and deposits
Technical sophistication, enforcement difficulty is high, big to existing traffic impact the characteristics of, therefore bridge spells wide design becomes highway reconstruction and expansion
The emphasis of engineering.By the proof of exploration for many years and many engineering practices, bridge widening transformation has been formd both at home and abroad
The primary structure of technology, currently used bridge widening joining method have three kinds：1. the superstructure and lower junction of new, old bridge
Structure is not connected to；2. the superstructure and substructure of new, old bridge are all connected with；3. new, old bridge superstructure connection, under
Portion's structure is not connected to.
1. connecting method requires to reserve a longitudinal construction joint between new bridge and old bridge, make new bridge and old bridge each by
Power, will not interact, construction is simple, and there is no the technical barrier of new, old bridge connection.But due to new bridge and old bridge phase
It is mutually independent, and active time differs, therefore can be led under outer load action there is a phenomenon where new, old bridge deformation
Cause bridge floor to produce vertical bridge to crack and direction across bridge faulting of slab ends, influence to widen the normal use of rear axle girder construction.
Connecting method is 2. mainly by being implanted into the modes such as reinforcing bar, casting concrete connector by new bridge superstructure and old
The corresponding position of bridge superstructure connects, while adopts new bridge substructure and old bridge substructure in a like fashion
Also it is attached, new bridge and old bridge is formed entirety, common stress.But the bridge structure after 2. being widened using connecting method
It is very sensitive to the foundation settlement difference of new, old bridge, when the foundation settlement difference of the relatively old bridge of new bridge is larger, new, old bridge
Substructure junction can produce larger additional internal force, if additional internal force is excessive, junction can be caused crack, shadow occur
It is beautiful to ring bridge, reduces performance；Make at the same time in new, old concrete shrinkage and creep difference or new and old Bridge Foundation differential settlement
Under, new and old bridge superstructure junction can also produce larger additional internal force, it is also possible to crack occur, influence bridge beauty
With road-ability.
Connecting method is 3. by being implanted into reinforcing bar, integral cast-in-situ concrete connector（It is wet to connect section or diaphragm plate）Will etc. mode
Newly, old bridge superstructure connection, for substructure then by the way of construction joint is stayed without connection.On the one hand can make it is new,
Old bridge superstructure connects integral, common stress, favourable to the stress of old bridge；On the other hand, new, old bridge substructure
It is not connected to, respective stress is independent of each other, and has both avoided the technical barrier of new, old bridge substructure connection, it is difficult to reduce construction
Degree, reduces engineering cost, turn avoid new and old Bridge Foundation settlement difference and adversely affected caused by widening bridge.It is domestic at present
Shanghai-Nanjing Expressway, Shanghai-Hangzhou-Ningbo highway, even multiple expansions such as highway Zhengzhou section, Beijing-Hongkong Australia highway stone peace section suddenly
This connecting method is employed in engineering of founding a capital.
But when 3. being spliced using connecting method to new, old bridge girder, old bridge has runed considerably long one
Section time, the concrete shrinkage of its girder, time deformation have been completed and tended towards stability, and under action of long-term load, especially
Be concrete shrinkage effect under, new bridge girder vertical bridge to generation contraction distortion；On the other hand, indulge bridge and spell wide connect to concrete
The presence of fitting make it that the vertical bridge of new bridge girder is constrained to contraction distortion be subject to old bridge girder, is shunk, slowly in new, old concrete
Become under difference effect, cause to widen rear overall structure and produce direction across bridge flexural deformation, and maximum appears in abutment or one
Transition pier position.Since the bearing that the bridge that early stage builds uses is usually common laminated rubber bearing, its deformability is small, this
Old bridge seat direction across bridge displacement after new, old bridge spelling can be caused wide is excessive, and failure by shear occurs, influences the normal of such bridge
Use.
