Abstract
The present invention relates to a kind of railway multi pylon cable stayed bridge structural systems, including girder and more floor lamp cage type bridge towers；Bird-caging bridge tower includes four king-posts, and every king-post is followed successively by upper king-post strut, middle king-post and lower king-post strut from top to bottom；All middle king-posts are gradually drawn close upwards, and overall structure is formed in upper king-post strut position；All lower king-post struts are gradually drawn close downwards, and overall structure is formed in lower king-post strut bottom；Four horizontal crossbeams are arranged between the middle king-post bottom of four king-posts to connect four king-posts, girder sequentially passes through more floor lamp cage type bridge towers and is placed in above crossbeam.The present invention can provide larger rigidity, the railway transportation requirement high to rigidity of structure demand can be met, longitudinal double-row beam bottom bearing, lateral wind-resistant support or damper are set for girder at Sarasota and provide enough installation spaces, keeps the force-mechanism of multitower multispan formula cable-stayed bridge more reasonable.
Description
Technical field
The invention belongs to bridge structure technical field of buildings, and in particular to a kind of railway multi pylon cable stayed bridge structural system.
Background technology
Cable-stayed bridge can be divided into only tower double-span formula, three straddle type of double tower and multitower multispan according to the difference of span arrangement mode
Formula.Three straddle type cable-stayed bridge of double tower is most common structural style, and multitower multispan formula seldom uses, and main cause is：
1, when a certain middle span of the load action in multi pylon cable stayed bridge, due to intermediate Sarasota side anchor rope do not have auxiliary pier to fix,
Adjacent across girder rigidity is smaller simultaneously, and intermediate Sarasota horizontal displacement is caused to increase, and causes total deformation excessive, structure is whole
Rigidity is weaker, cannot be satisfied requirement of the railroad bridge to the rigidity of structure.
2, main bridge continuous length is longer, and mobile load influences line length and range increases, and each component mobile load effect becomes larger, wherein most
Outside king-tower bottom of tower moment of flexure is larger, and member stress cannot be satisfied the requirement of normal operating condition.
But when across the unfavorable terrains such as marine environment or Grand Canyon, by navigation requirement, terrain, beauty and other
The restrictive condition of aspect generally requires to use multitower multispan formula Cable-stayed Bridge Scheme.
Invention content
The object of the present invention is to provide a kind of railway multi pylon cable stayed bridge structural systems, make the stress of multitower multispan formula cable-stayed bridge
Mechanism is more reasonable.
The technical solution adopted in the present invention is：
Railway multi pylon cable stayed bridge structural system, it is characterised in that：
Including girder and more floor lamp cage type bridge towers；
Bird-caging bridge tower includes four king-posts, and every king-post is followed successively by upper king-post strut, middle king-post and lower king-post strut from top to bottom；In all
King-post is gradually drawn close upwards, and overall structure is formed in upper king-post strut position；All lower king-post struts are gradually drawn close downwards, in lower king-post strut bottom
Form overall structure；
Four horizontal crossbeams are arranged between the middle king-post bottom of four king-posts to connect four king-posts, girder sequentially passes through more
Bird-caging bridge tower is placed in above crossbeam.
Four beam bottom bearings are arranged in bottom plane of main girder at each bird-caging bridge tower, and girder is placed in crossbeam by four beam bottom bearings
Top.
Gap is set between girder side and king-post, and lateral wind-resistant support or damper are installed.
Suspension cable is set between bird-caging bridge tower upper king-post strut and lateral girder.
Girder end bay is provided with auxiliary pier.
The present invention has the following advantages：
1, the multi pylon cable stayed bridge structural system can provide larger rigidity, and it is high to rigidity of structure demand can to meet railway transportation
Requirement.
2, longitudinal double-row beam bottom bearing, lateral wind-resistant support or damper are set for girder at Sarasota and provide enough peaces
Fill space.

Specific implementation mode
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of railway multi pylon cable stayed bridge structural systems, including girder and more floor lamp cage type bridge towers 1.Bird-caging
Bridge tower 1 includes four king-posts, forms space structure so that 1 rigidity of bird-caging bridge tower increases considerably.Every king-post is from upper
Upper king-post strut 3, middle king-post 4 and lower king-post strut 5 are followed successively by under and；All middle king-posts 4 are gradually drawn close upwards, are formed in 3 position of upper king-post strut
Overall structure is conducive to the arrangement of suspension cable；All lower king-post struts 5 are gradually drawn close downwards, and whole knot is formed in 5 bottom of lower king-post strut
Structure is conducive to reduce dimension of platform.Four horizontal crossbeams 6 are set between 4 bottom of middle king-post of four king-posts by four king-posts
Connection, enhances the globality between king-post.Girder sequentially passes through more floor lamp cage type bridge towers 1 and is placed in 6 top of crossbeam.Bird-caging bridge tower
Suspension cable is set between 1 upper king-post strut 3 and lateral girder.Girder end bay is provided with auxiliary pier 2, improves the rigidity of end bay.
Double four beam bottom bearings 7 are arranged in each 1 bottom plane of main girder of bird-caging bridge tower, and girder is set by four beam bottom bearings 7
Above crossbeam 6, after girder uses longitudinal double-row beam bottom bearing 7, girder span, and the rotation displacement at king-tower are reduced
Restrained, span centre displacement is reduced, and improves girder rigidity；Girder load is directly delivered to lower king-post strut by double beam bottom bearing 7
5, the stress of upper king-post strut 3 is reduced, girder rigidity is improved.Gap is set between girder side and king-post, and transverse direction is installed
Wind-resistant support 8 or damper.Bird-caging bridge tower 1 need to be that longitudinal double-row beam bottom bearing 7, lateral wind-resistant support 8 or resistance is arranged in girder
Buddhist nun's device provides enough installation spaces.
Present disclosure is not limited to cited by embodiment, and those of ordinary skill in the art are by reading description of the invention
And to any equivalent transformation that technical solution of the present invention is taken, it is that claim of the invention is covered.
