Description

A kind of high pier structure of the hyperboloid of one sheet of urban viaduct
Technical field
The invention belongs to science of bridge building field, it is related to a kind of bridge pier structure form, specifically a kind of list of urban viaduct The high pier structure of hyperboloid of two sheets.
Background technology
With continuing to develop for urban construction, urban traffic blocking is serious, to alleviate traffic pressure, starts to build city height Frame express passway, the traffic that nowadays Urban Bridge has been played as urban road is acted on.The high pier of urban viaduct is located at 2 layers, 3 layer intercommunication grade separations are built in main traffic crossing, transport hub, and urban viaduct is towards higher, bigger, more complicated direction Development so that bridge pier column height is more than 20 meters.Bridge is the mankind according to the one kind built the need for life and production development Public building, people begin to focus on the aesthetics of bridge, urban viaduct high pier position on the basis of bridge is met using function In traffic main artery crossing, geographical position is special, it is necessary to meet safety and two attractive in appearance requirements.One kind is needed in urban viaduct construction badly Economical and beautiful high bridge pier structure, so as to beautifying city space and the open driver visual field.
The content of the invention
Goal of the invention:In order to overcome the deficiencies in the prior art, the present invention provides a kind of single leaf of urban viaduct The high pier structure of hyperboloid.
Technical scheme:In order to solve the above technical problems, a kind of high pier knot of the hyperboloid of one sheet of urban viaduct of the present invention Structure, including hyperboloid of one sheet pier shaft, hyperboloid of one sheet pier shaft profile are hyperboloid of one sheet ruled surface configuration, hyperboloid of one sheet pier shaft Including stress cage bar, oval stirrup, elliptic steel pipe and pier shaft concrete, stress cage bar is divided into two groups, space crossed arrangement, its sky Between be configured as the hyperboloid of one sheet space cylinder it is netted;Including following construction procedure:
Step one:Setting-out, squeezes into pile foundation, foundation platform of constructing;
Step 2:Stress cage bar blanking, according to hyperboloid of one sheet dimensional network shape configuration, space crossed arrangement is advocated Muscle, spiral wound ellipse stirrup, forms framework of steel reinforcement, and oval steel pipe is inserted in pier shaft center, and installation form is poured Pier shaft concrete, forms hyperboloid of one sheet pier shaft;
Step 3:Construction pier cap, bearing cushion block, erection support, box girder erection, railing of constructing, bridge floor of mating formation forms bridge Beam.
Beneficial effect:A kind of high pier structure of the hyperboloid of one sheet of urban viaduct of the present invention, has the advantages that:
With the communication continued to develop, the status of bridge seems more and more important, and people use work(meeting bridge The aesthetics of bridge is begun to focus on the basis of energy, bridge aesthetics turns into a raft of pontoons beam art of architecture.
The present invention follows the refreshing structure stress of overhead road of city bridge pier rationally and two principles of bridge aesthetics, utilizes the hyperboloid of one sheet Straight burr characteristic, arrangement steel bar stress is into dimensional network shape, and spiral wound ellipse stirrup sets oval in pier shaft center Steel pipe, forms framework of steel reinforcement, makes template, and casting concrete forms hyperboloid of one sheet bridge pier structure.
Existing bridge pier structure form species is more, more or less there is problem for urban viaduct.Single column pier has Structure is simple and direct, floor space is small, broad view and the advantages of good economy performance, but its stability against overturning is poor, there is potential safety hazard. Twin shaft pier has the advantages that structure is simple and direct, stability against overturning is good and good economy performance, but it has that floor space is big and influence department The shortcomings of machine sight.Thin-Wall Piers have the advantages that structure is simple and direct, stability against overturning is good and good economy performance, but aesthetic effect difference and Influence driver's sight.Y shape bridge pier has the advantages that stress performance is good and beautiful attractive in appearance, but complex-shaped and assembling reinforcement construction It is difficult.
Compared with existing bridge pier, the high pier of the hyperboloid of one sheet first receive put afterwards be small rough waist stature, it is beautiful attractive in appearance.Single leaf hyperbolic The tiny waist of the high pier in face, the open visual field of driver.
The Dun Qiao of the present invention has the profile of the hyperboloid of one sheet, and bridge pier waist is tiny, and bridge pier bottom is abundant, conforms to bridge pier curved Square diagram shape, the sturdy bottom of new curve bridge pier, it is ensured that bridge pier bending resistance shear-carrying capacity.
The hyperboloid of one sheet bridge pier of the present invention has wider top, it is ensured that enough distances between box beam double support, Be conducive to box girder bridge stability against overturning.
Using the straight burr characteristic of the hyperboloid of one sheet, steel bar stress is arranged to netted, the straight line steel bar stress of space cylinder, Assembling reinforcement convenient and quick construction, then the oval stirrup of spiral wound, can form firm framework of steel reinforcement.
Hyperboloid of one sheet bridge pier uses flattened oval pier shaft, and pier shaft waist is tiny, has saved concrete amount, reduces Bridge pier construction costs.
The pier bridge pier of the present invention sets elliptic steel pipe in bridge pier center, improves the resistance to compression carrying of pier shaft structure Power, with improving bridge pier anti-earthquake ductility and energy dissipation capacity, can meet big shake less than requirement.Pier shaft elliptic steel pipe can be used as construction The support column of temporary platform, convenient construction personnel, which enter inside pier shaft, pours vibrated concrete, advantageously ensures that primary concreting The quality of pier shaft clear-water concrete.
The hyperboloid of one sheet bridge pier structure of the present invention has reasonable structure stress, beautiful, driver's broad view attractive in appearance, resists and incline Cover the advantages of good stability, good anti-earthquake ductility and easy construction, the high bridge pier structure available for urban viaduct.
