Build bridge for Regional Road Network to optimize and improve and have laid a good foundation, the also development to city and social economy has important work
With for the concrete box girder cantilever of conventional overhead bridge when that need to increase boom width because load limits, structure cantilever root is thick
Degree need to increase bigger, cause space under bridge small, be unfavorable for vehicle pass-through, meanwhile, the degree of disturbing of cantilever end is also larger, loses smooth-going
The comfort level of driving;Box beam need to laterally increase transverse prestress, and difficulty of construction is very big.
Utility model content
In view of this, the purpose of this utility model is to provide that a kind of structure is novel, and good big of stability chooses arm elevated bridge
Structure.
The utility model is realized using following scheme:A kind of to choose arm overhead bridge structure greatly, the bridge is included in being located at
The bridge main body in portion and choose arm positioned at bridge main body both sides, choose arm bottom be spaced and chosen along bridge length direction arm and
The floor that bridge main body is connected as a single entity, multiple chambers are arranged at intervals with along bridge width direction inside bridge main body.
The hook portion chosen arm outer side edges and bent downwards along having, hook portion are internally provided with drainpipe, and floor bottom is set
There is the drip on the inside of hook portion, the floor is wedge structure, and floor small end is headed on the inside of hook portion, and the big end of floor heads on bridge
Beam body side.
Further, the arm width of choosing is 540cm, and the floor thickness is 50cm, the center between adjacent two floor
Away from for 300 ~ 400cm.
Further, the arm of choosing includes thickness by the small trapezoidal portion of interior gradual change outward and the flat part of consistency of thickness, trapezoidal
Portion's width is 200cm, and be connected with the bridge main body thickness at end of trapezoidal portion is 50cm, and the thickness at the end that is connected with flat part is
20cm, flat part thickness are 20cm, and the hook portion is located at flat part outer side edges edge.
Further, chamber sidepiece offers air vent, and chamber bottom is provided with spilled water hole, chamber bottom and adjacent two
It is provided with web between chamber and enters manhole for what people passed through.
Further, the bridge floor of the bridge is the low slope structure in middle high both sides, and the both sides gradient is 2%.
Compared with prior art, the utility model has the advantages that:The utility model chooses greatly arm elevated bridge knot
There is structure box beam to choose the features such as arm is big, and chamber is wide, and bearing spacing is small, is adjusted to two-way Slab element stress, is meeting structure stress
On the basis of, avoid broad flange beam from using transverse prestress, greatly simplify construction technology, meet U.S. while ensureing safe again
Sight demand, space under bridge is fully saved on the premise of bridge lateral stability and security is ensured, beneficial to vehicle pass-through, alleviated
The traffic pressure in city city, while the degree of disturbing of cantilever end is also smaller, ensures the comfort level of smooth-going driving.
For the purpose of this utility model, technical scheme and advantage is more clearly understood, specific embodiment will be passed through below
And relevant drawings, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the utility model embodiment transverse cross-sectional view;
Fig. 2 is the utility model embodiment top view;
Label declaration in figure:1- bridge main bodies, 2- choose arm, 3- floors, 4- chambers, 5- hook portions, 6- drainpipes, 7- and dripped
