Abstract
The utility model relates to a large-span V-shaped continuous rigid framework bridge. A V-shaped rigid framework is arranged at the lower edge of a support point for main beam. A pier column is arranged at the lower edge of the V-shaped framework. The pier column is connected with a bearing platform and a pile. Approaches arranged at both sides are respectively designed in the way that the lower branch of pre-stressed concrete simple span T-beam is connected with a pier; the main beam is concreted with the pier. As forces are applied to the top and bottom structures cooperatively, the negative moment of the section of a box girder arranged on the top of the pier is reduced, thus being beneficial to decreasing the beam depth. The high and slender pier and low anti-thrust rigidity in axial direction of bridge effectively reduce the influences that the temperature and concrete shrinkage have. The structure has good integrity, excellent earthquake resistant capability, and large bending rigidity and transverse torisonal rigidity in axial direction of bridge, thus meeting the stressing requirement for stress by the bridge with extra long span and furthest extending the service life of the bridge. The bridge is characterized by a novel and beautiful shape, the V-shaped rigid framework reduces the main span and the dimension of the section decreases, so the bridge is lighter and smaller, has good structural integrity, is characterized by convenient construction, and has low cost..
Description
Technical field
The utility model relates to architecture bridge construction field, is specifically related to a kind of continuous rigid frame bridge that adopts the two dimension prestressing building.
Background technology
The continuous rigid frame system is a kind of new structure that grows up from continuous beam, obtains the sixties in 20th century to develop faster and be widely used.The girder and the bridge pier of continuous rigid frame bridge are fixed, and upper and lower part structure cooperative bearing makes the hogging moment of Dun Ding place case beam section reduce, and helps reducing deck-molding.Bridge pier Gao Errou, to push away rigidity little to anti-along bridge, the influence of can reduce temperature and concrete shrinkage effectively, creeping; Structural integrity is good, and anti-seismic performance is excellent, and is big to bending rigidity and horizontal torsional rigidity along bridge, can satisfy the force request of large span bridge.Therefore say that the continuous rigid frame bridge can prolong the application life of bridge to greatest extent.But appropriate design scheme in actual applications still belongs to vacancy.
Summary of the invention
The purpose of this utility model is to remedy defective of the prior art, provide a kind of stressed rationally, the large span V-type continuous rigid frame bridge of good integrity.
The purpose of this utility model is achieved through the following technical solutions.
A kind of large span V-type continuous rigid frame bridge, it comprises girder, the firm structure of V-type, pier stud, cushion cap, pile foundation and connection pier; Lower edge is provided with the firm structure of V-type at the fulcrum place of girder, and the firm structure lower edge of V-type is equipped with pier stud, and pier stud connects cushion cap, and cushion cap connects pile foundation; The access bridge at two ends adopts prestressed concrete freely-supported T beam respectively, props up the connection pier down.
Described girder adopts variable cross-section list case double-chamber structure, and the curvilinear equation that its depth of section changes is the second-degree parabola of rotation, and the joining place of firm structure of V-type and girder is by suitable concrete beam or the prestressed girder of connecing of curve.
The firm structure of described V-type can adopt concrete-filled steel tubular hollow, steel reinforced concrete, round steel concrete or square steel concrete.
Large span V-type continuous rigid frame bridge of the present utility model is the continuous girder bridge of pier beam consolidation.Because this system utilizes the flexibility of main pier to adapt to the longitudinal strain of bridge, so more suitable in striding high pier greatly.Integrality performance of the structure is good, and antitorque potentiality are big, and the pontic brevity and lucidity is easy to maintenance.Both kept continuous beam not have shrinkage joint, the smooth-going advantage of driving, had bigger suitable bridge again, and can satisfy the force request of bridge with super-large span to bending rigidity and horizontal torsional rigidity.The V-type continuous rigid frame is compared with continuous beam, and aspect stressed, superstructure still has the characteristics of continuous beam.Because continuous rigid frame is the pier beam consolidation, has removed the bearing on the Dun Ding from, can save the expensive expense of large-scale bearing, reduces the engineering quantity on pier and basis, and improved the mechanical property of structure under horizontal loads.The V-type continuous rigid frame is the structural shape that new development is in recent years got up, the bridge type novel and beautiful, and the V support reduces main span and strides the footpath, and cross dimensions reduces, and seems lighter and handier, and structural integrity is good, easy construction, cost is lower.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of the utility model large span V-type continuous rigid frame bridge.
Among the figure: 1, girder, 2, the firm structure of V-type, 3, pier stud, 4, cushion cap, 5, pile foundation, 6, connect pier.
The specific embodiment
Referring to accompanying drawing, large span V-type continuous rigid frame bridge comprises girder 1, the firm structure 2 of V-type, pier stud 3, cushion cap 4, pile foundation 5 and connects pier 6, girder 1 fulcrum place lower edge is the firm structure 2 of V-type, firm structure 2 lower edges of V-type have pier stud 3, be cushion cap 4 below the pier stud 3, and cushion cap 4 is following to be pile foundation 5.The access bridge at two ends adopts following connection pier 6 of prestressed concrete freely-supported T beam respectively.Girder 1 employing variable cross-section list case double-chamber structure, the curvilinear equation that its depth of section changes is the second-degree parabola of rotation, firm structure 2 of V-type and girder 1 joining place are by suitable concrete beam or the prestressed girder of connecing of curve.The firm structure 2 of V-type can adopt concrete-filled steel tubular hollow, steel reinforced concrete, round steel concrete or square steel concrete.
The firm structure 2 of V-type also can be called for short V support 2, and V support 2 connects with curve is suitable with girder 1 joining place.Main pier pier stud 3 is the concrete rectangular pier shaft, on connect V support 2, add vertical prestressing in the V support 2.Under connect cushion cap 4, cushion cap is for 4 times a bored pile foundation 5.
Main bridge superstructure is a prestressed concrete V-type continuous rigid frame, and the two ends access bridge is used prestressed concrete freely-supported T beam respectively.
Girder 1 employing variable cross-section list case double-chamber structure, depth of section change curve equation is the second-degree parabola of rotation, V support 2 connects with curve is suitable with the joining place of girder 1.The base plate gradual change that girder beam-ends and close V support 2 places is thick.
Connect pier 6 and adopt two firmly bridge piers, bent cap is a T section, connects cushion cap 4 under the post, and cushion cap 4 is I-shaped, and it is bored pile foundation 5 down.
When building, can adopt following steps:
1) banket the compression river course lay multi-column pier foundation in the river bed;
