Abstract
The utility model belongs to technical field of bridge engineering, is specifically related to the only tower of a kind of railway and mixes girder stayed-cable bridge structure.It comprises bridge main beam, described bridge main beam is provided with a bridge tower, multiple skew cables is provided with between described bridge tower top and bridge main beam top, the end bay of described bridge main beam is concrete box girder construction, and the main span of bridge main beam and end bay one section of joining is concrete structure, be steel box girder away from another section of end bay.Cable stayed bridge of the present utility model, when rigidity meets the requirement of railways train operation ride comfort, only arranges a bridge tower, and structure is simple, greatly reduces suspension cable consumption, reduces construction costs; Bridge main beam adopts the hybrid beam that is combined with girder steel of concrete beam, meet structural bearing capacity, rigidity, requirement, economy is better.
Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to the only tower of a kind of railway and mixes girder stayed-cable bridge structure.
Background technology
The various bridge types of railroad bridge all have the different scope of application for span, and cable stayed bridge is as line structure, and span ability is strong, applies more in large-span structure.At present, what the Railway Cable-stayed Bridge of large span all adopted is Double-Tower Structure, but the cable stayed bridge of Double-Tower Structure be mainly applicable to span more than 400 meters (left and right) bridge main across, and for the Cable-Stayed Bridge Structure of main span span at 230m-350m, if still adopt Double-Tower Structure, because span is less, the performance of material can not get fully playing, and causes waste economically.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed to solve above-mentioned background technology, provides the only tower of railway that a kind of structure is simple, cost is low to mix girder stayed-cable bridge structure.
The technical solution adopted in the utility model is: the only tower of a kind of railway mixes girder stayed-cable bridge structure, comprise bridge main beam, described bridge main beam is provided with a bridge tower, multiple skew cables is provided with between bridge tower top and bridge main beam top, the end bay of described bridge main beam is concrete box girder construction, and the main span of bridge main beam and end bay one section of joining is concrete structure, be steel box girder away from another section of end bay.
Further, bottom described bridge tower with between bridge main beam, bottom bridge tower with between bridge pier by being all connected by seat structure.
Further, described main span span is 230m-350m.
Cable stayed bridge of the present utility model, when rigidity meets the requirement of railways train operation ride comfort, only arranges a bridge tower, and structure is simple, greatly reduces suspension cable consumption, reduces construction costs; Bridge main beam adopts the hybrid beam that is combined with girder steel of concrete beam, meet structural bearing capacity, rigidity, requirement, economy is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-bridge main beam; 2-bridge tower; 3-suspension cable; 4-end bay; 5-main span; 6-bridge pier.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Figure 1, main span 5 span of Cable-Stayed Bridge Structure of the present utility model is between 230m-350m, and it comprises bridge main beam 1, and described bridge main beam 1 is provided with a bridge tower 2, is provided with multiple skew cables 3 between described bridge tower 2 top and bridge main beam 1 top.The end bay 4 of described bridge main beam 1 is concrete box girder construction, and the main span of bridge main beam 15 and end bay one section of join is concrete structure, be steel box girder away from another section of end bay.For hybrid beam cable stayed bridge, choose rational girder steel and rod coagulates native beam link position, i.e. position, steel reinforced concrete joint portion, need the key issue that first solves in the design of such bridge type and construction, position, joint portion determines on the one hand the length ratio of weight and the very large girder steel of stiffness differences and concrete beam, on full bridge structure, particularly girder is overall stressedly has impact, span setting need be considered, auxiliary pier is arranged, tower beam constraints, the impact of the many factors such as suspension cable fatigue behaviour, the overall structure performance of hybrid beam cable stayed bridge significantly can be improved in position, rational joint portion, from joint portion, self local is considered on the other hand, for preventing concrete cracking, position, rational joint portion also should be selected in the less place of girder moment of flexure, therefore, after considering comprehensively have factor, the length ratio between the concrete box girder construction of the utility model main span 5 and steel box girder is preferably 0.88.
The utility model Sarasota adopts brilliant Sarasota, and the above Sarasota of bridge floor adopts Y shape, and bridge floor inside contracts as diamond with lower king-post strut, and main pier foundation adopts Bored Pile Foundation, and bridge tower adopts concrete towers, and abutment pier, auxiliary pier basis all adopt drilled pile.Suspension cable adopts the zinc-plated parallel wire stay of tension normal intensity 1670MPa.This bridge general construction system is the form that tower beam is separated, i.e. plate floating system, bearing and longitudinal damper are set between tower beam, are connected with longitudinal damper by bearing bottom bridge tower 2 with between bridge main beam 1, be connected by equal seat structure with between bridge pier 6 bottom bridge tower 2.
The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
