The utility model discloses adopt straight bridge form because the ribbon encircles main bridge, the curved bridge is made on the plane, and the atress is reasonable, and the construction technology degree of difficulty reduces, and overall structure is succinct, firm, and bridge plane curve form and half -through ribbon arch rib are aesthetic in appearance.
Description
Technical field
This utility model is related to bridge road technology field, and in particular to boundless across half-through tie-rod ribbon arch bridge.
Background technology
Modern city bridge construction except meeting traffic in terms of demand in addition to, more and more start focus on landscape above
Design, particularly with the bridge that upper zone is required positioned at landscape.Having distinctive bridge main in moulding will have cable-stayed bridge, suspension cable
Bridge, arch bridge, it is now domestic to cable-stayed bridge and suspension bridge in terms of research it is relatively more, arch bridge especially boundless across half-through tied arch
It is fewer.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of boundless across half-through tie-rod ribbon arch bridge, ribbon arch master
Bridge adopts straight bridge form, plane to make curved bridge, and reasonable stress, construction difficulty is reduced, and external form is succinctly attractive in appearance.
This utility model is achieved through the following technical solutions：
Boundless across half-through tie-rod ribbon arch bridge, including the access bridge at two ends and middle main bridge, main bridge both sides arrange " m " shape
Ribbon arch rib, ribbon arch rib includes side arch rib and major arch rib, the relative ribbon arch rib footing portion connection arch rib in main bridge both sides
Crossbeam, the main bridge superstructure of cast-in-place three sections of continuous beam-arch combined systems on arch rib crossbeam, main bridge girder is straight bridge, and bridge floor adds
Width, bridge floor edge footpath is arranged to curve according to road surface direction.
The further improvement project of this utility model is that ribbon arch rib slopes inwardly 26 °.
This utility model further improvement project is, in main bridge girder and ribbon arch rib intersection, the outer abdomen of main bridge girder
Plate disconnects, and does not help with ribbon arch and is connected, and gap location is filled using rubber cushion blocks.
This utility model further improvement project is that main bridge girder is rotated at end floor beam and middle cross beam using five bearings
On the arch rib crossbeam of relevant position.
This utility model further improvement project is that ribbon arch rib is made up of three parts, i.e. the concrete arch feet of bottom
Point, the steel construction at middle toughened internal stress and top.
This utility model further improvement project is that concrete arch springing part is using finish rolling deformed bar prestressed stretch-draw and concrete
Outer surface external application carbon fiber.Because moment of flexure is larger at concrete arch springing, crack is easily produced, the structure reduces crack as far as possible.
This utility model further improvement project is that pier of main beam is multi-column pier foundation, and access bridge bridge pier is pile-column basis,
Basis is bored pile foundation.Access bridge is adopted and main bridge separate structure, the pile-column of access bridge bridge pier bottom independence, is not shelved
On cross beam of main bridge, so that structure of main bridge stress is clear and definite.
This utility model further improvement project is that access bridge superstructure is freely-supported cast-in-situ box girder.
This utility model further improvement project is that side arch rib is highly less than major arch rib height, both sides main arch arch
Rib top is connected by crossbeam.It is simple for structure, attractive in appearance, firm.
This utility model further improvement project is that host bridge is provided with D80 and stretches with the superstructure junction of access bridge
Contracting seam, at the superstructure of access bridge bridge pier top position GQF-C-40 expansion joints are provided with.
This utility model compared with prior art, with following obvious advantage：
This utility model adopts straight bridge form, plane to make curved bridge, reasonable stress, construction technology because ribbon encircles main bridge
Difficulty is reduced；Access bridge is adopted and main bridge separate structure, so that structure of main bridge stress is clearly, terminal with compact integral structure, firm, U.S.
See.
Description of the drawings
Fig. 1 is this utility model side structure schematic view.
Fig. 2 is the A-A sectional views of Fig. 1.
Fig. 3 is this utility model top view.
Specific embodiment
As shown in Figure 1 to Figure 3, this utility model be boundless across half-through tie-rod ribbon arch bridge, including the access bridge 1 at two ends with
Middle main bridge 2, substructure pier of main beam 21 is multi-column pier foundation, and access bridge bridge pier 11 is pile-column basis, and basis fills for drilling
Note pile foundation, abutment connects barrier wall structure using wall side, and access bridge is adopted and main bridge separate structure, so that structure of main bridge stress
Clearly, the both sides of main bridge 2 arrange " m " shape ribbon arch rib 3, and ribbon arch rib 3 slopes inwardly 26 °, and ribbon arch rib 3 includes side arch rib 31
With major arch rib 32, the relative ribbon arch rib footing portion in main bridge both sides connects arch rib crossbeam 33, cast-in-place three sections on arch rib crossbeam 33
The main bridge superstructure of continuous beam-arch combined system, the girder of main bridge 2 is straight bridge, in the headroom for ensureing bridge floor functional bands and pedestrian
Under requirement, deck widening, bridge floor edge footpath is arranged to curve according to road surface direction, and access bridge superstructure adopts the cast-in-place case of freely-supported
Beam, bridge plane is located on the curved section of circle bilge radius.
In the girder of main bridge 2 and the intersection of ribbon arch rib 3, the outer web of main bridge girder disconnects, and does not help with ribbon arch and is connected, gap
Place is filled using rubber cushion blocks, and the arch rib that main bridge girder rotates on relevant position at end floor beam and middle cross beam using five bearings is horizontal
Liang Shang.
Ribbon arch rib 3 is made up of three parts, i.e. the concrete arch springing part 311 of bottom, middle toughened internal stress 322 and top
