Abstract
A kind of bionical special-shaped continuous arch structural bridge of bird type, with meet Bridges it is slim and graceful while sufficiently achieve the requirement of arch bridge reasonable mechanical.Including main arch, girder and sunpender, the upper and lower ends of sunpender distinguish anchor connection main arch, girder.The main arch along bridge to the first arch rib, the second arch rib being extended continuously from constituting, ellipse or multiple parabola that the arch use of the first arch rib, the second arch rib deforms.First arch rib, the second arch rib are made of in direction across bridge left side main arch, right side main arch, and left side main arch, right side main arch are from bottom to top gradually drawn close, and are integrated in dome portions, are in herringbone.
Description
Technical field
The utility model relates to bridge, in particular to the bionical special-shaped continuous arch structural bridge of a kind of bird type.
Background technique
In recent years, the economic level in China is greatly improved and improves, people's lives idea and sense of living
Variation also constantly occurs for thought, and the idea for the environmental protection and saving that especially China was advocated in recent years even more builds for China and goes
The development of industry brings new opportunity, still to specific engineering construction, nothing either on the foundation structure of building enterprise
One biggish variation does not occur.In order to effectively push the long-range of China's building trade and develop in a healthy way, bridge optimization and
Bionic Idea is just largely used in design work, the main purpose using bionical idea is exactly to use bridge
Some problems present in journey are subject to effective solution, preferably provide for the development of Bridges in Our Country and scientific instruct work.
The design work of bridge is a branch particularly important in China's engineering construction, the long term growth one of construction business
Determine the new intention and inspiration that designer is depended in degree, therefore, application of the bionics in Bridge Design will certainly be more preferable
Promotion bridge function and moulding constantly bring forth new ideas, this is for preferably ensureing that the development of Bridges in Our Country construction business has very
Important meaning and effect.
Utility model content
The technical problem to be solved by the utility model is to provide the special-shaped continuous arch structural bridge that a kind of bird type is bionical, with
Meet Bridges it is slim and graceful while sufficiently achieve the requirement of arch bridge reasonable mechanical.
It is as follows that the utility model solves technical solution used by its technical problem:
A kind of bionical special-shaped continuous arch structural bridge of bird type of the utility model, including main arch, girder and sunpender, sunpender
Upper and lower ends distinguish anchor connection main arch, girder, it is characterized in that: the main arch from along bridge to the first arch rib being extended continuously, the
Two arch ribs are constituted, the ellipse or multiple parabola that the arch use of the first arch rib, the second arch rib deforms；First arch
Rib, the second arch rib are made of in direction across bridge left side main arch, right side main arch, and left side main arch, right side main arch are from bottom to top gradually drawn close,
And be integrated in dome portions, it is in herringbone.
The girder uses fish-bellied type section box beam, on direction across bridge gradually by longitudinal centre line to both sides of the edge its thickness
It is thinned.
The utility model has the beneficial effects that direction across bridge gradually becomes single main arch by double main arch, in the feelings of reasonable stress
Keep moulding slimmer and more graceful under condition, saves construction material；Along bridge to the first arch rib, the bionical flying bird moulding of spreading the wings of the second arch rib, both changed
Landscape effect that is kind and improving bridge, and provide more choices for the line style and appearance of arch bridge；Bridge type transverse and longitudinal curved shape
In conjunction with structurally reasonable, stress is clear, reduces construction material dosage, and the moulded grace of bridge, highlights light succinct
Aesthetic feeling；Girder uses fish-bellied type section box beam, and while keeping moulding more beautiful, more traditional Bridge Sections, which are more saved, builds material
Material, can effectively reduce bridge construction cost.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is a kind of elevation of the bionical special-shaped continuous arch structural bridge of bird type of the utility model；
Fig. 2 is a kind of cross-section diagram of the bionical special-shaped continuous arch structural bridge of bird type of the utility model；
Fig. 3 is a kind of top view of the bionical special-shaped continuous arch structural bridge of bird type of the utility model.
Component and corresponding label: the first arch rib 11, the second arch rib 12, left side main arch 13, right side main arch are shown in figure
14, girder 20, sunpender 21.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Figure 1 and Figure 3, the bionical special-shaped continuous arch structural bridge of a kind of bird type of the utility model, including main arch, girder
20 and sunpender 21, the upper and lower ends of sunpender 21 distinguish anchor connection main arch, girder 20.The main arch from along bridge to being extended continuously
First arch rib 11, the second arch rib 12 are constituted, the ellipse or multiple that the arch use of the first arch rib 11, the second arch rib 12 deforms
Parabola.With the first arch rib 11, the bionical flying bird moulding of spreading the wings of the second arch rib 12, the landscape effect of bridge had both been improved,
It provides more choices again for the line style of arch bridge and appearance.Referring to Fig. 2, first arch rib 11, the second arch rib 12 are in cross-bridges
It is constituted to by left side main arch 13, right side main arch 14, left side main arch 13, right side main arch 14 are from bottom to top gradually drawn close, and in vault
Portion is integrated, and is in herringbone.Direction across bridge gradually becomes single main arch by double main arch, and moulding is made in the case where reasonable stress more
Merrily and lightheartedly, construction material is saved.Referring to Figure 1 and Figure 3, the utility model bridge type transverse and longitudinal curved shape combines, and structurally reasonable, stress is bright
Really, reduce construction material dosage, and the moulded grace of bridge, highlight light succinct aesthetic feeling.
Construction material is saved referring to Fig. 2, while to make handsome in appearance and bridge construction cost, the girder is effectively reduced
20 use fish-bellied type section box beam, and by longitudinal centre line to both sides of the edge, its thickness is gradually thinned on direction across bridge.Under sunpender 21
End is connected to the pull rod area at 20 center of girder.
It referring to Fig.1, is the landscape effect for further increasing bridge, the sunpender 21 is by the first arch rib 11, the second arch rib 12
Vault to bridge floor center in divergent shape lay.The height and span of first arch rib 11 be greater than the second arch rib 12 height and
Span.
It should be pointed out that the utility model a kind of special-shaped continuous arch that bird type is bionical described above that only explains through diagrams
Some principles of structure, due to be for the those of ordinary skill to same technique field be easy to carry out on this basis it is several
It modifies and changes.Therefore, this specification is not intended to for the utility model to be confined to shown and described specific structure and fit
With in range, therefore all corresponding modifications that may be utilized and equivalent, it is applied specially to belong to the utility model
Sharp range.
