Description
Technical field
The utility model relates to technical field of civil engineering, particularly relates to a kind of cable stayed bridge four rope face three body steel girder.
Background technology
At present, cable stayed bridge is the trend of accelerated development, especially at home, cable stayed bridge be more and more applied to China over strait, across river main artery engineering and urban traffic construction project.But totally see, comparatively obvious across footpath development trend, support technology development relatively lags behind.In tower, beam, rope three macrostructure, directly realize using function, major effect structure stress main beam structure pattern comparatively dull, monolithic girder is complete with its function, technology maturation, structure is simple, lay traditional feature, always in occupation of technocracy status, have impact on the development in pluralism of cable stayed bridge to a certain extent.
Cable stayed bridge is large at traffic volume, number of track-lines is many, and during beam body ultra-wide, traditional integral formula girder exists the problem that compliance declines.1. track increases, and under beam body widens situation, lateral stressed outstanding problem, starts to control girder height, needs to use lot of materials.2. the hanging beam weight increase all corresponding to loop wheel machine weight in construction, difficulty strengthens.3. often cause out with the combination of two limb Sarasota that structure is short and stout, ratio is not normal, moulding is not good.
The girder pattern of cable stayed bridge is also in development.Spit of fland nine bridge built up in the recent period, AngChuan Zhou bridge, the good bridge that continues have employed split type girder, itself and the combination of open side type Sarasota, with succinctly bold feature, embody the new approaches of cable stayed bridge construction.But owing to lacking systematic research and application, the compliance of split type girder, technical, safety and economy problems, do not obtain clear and definite answer yet at present, technology application is in isolated state, and technical development is not reported especially.
Utility model content
For the support technology lagging in development that above-mentioned domestic and international cable stayed bridge exists, integrated main beam type formula is more dull, it is restricted to use, safety is risky, difficulty of construction large and view is not good, and the problems such as split type girder technical advantage is fuzzy, technical development stagnation, the invention provides a kind of cable stayed bridge four rope face three body steel girder.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of cable stayed bridge four rope face three body steel girder, it is characterized in that: be made up of two limit steel girders, middle steel girder, gooseneck and four rope face drag-lines, described two limit steel girders are arranged on both sides, a middle steel girder is between two limit steel girders, described two limit steel girders are connected with gooseneck with a middle steel girder, with four rope face drag-line supportings.
Described middle steel girder is bearing in the middle part of gooseneck continuously, forms multiple spot elastomeric bearing continuous system with this.
Described limit steel girder from being bearing on himself both sides drag-line, and laterally forms four point elastic support on the steel girder of limit.
Described limit steel girder, middle steel girder, gooseneck are modularization separate unit, and horizontal bolt composition beam section, longitudinal measure forms girder.
The separate unit of described cable stayed bridge four rope face three body steel girder manufactures in factory's coupling, be transported to scene, adopt erection crane independent and the bilateral steel girder of synchronous lifting (being namely positioned at two limit steel girders on both sides), adopt the purlin car lifting gooseneck across bilateral steel girder, steel girder in adopting bridge floor Bridge Erector to install, laterally form entirety, longitudinally assembled piecemeal.
The beneficial effects of the utility model are:
Cable stayed bridge four rope face three body steel girder creates a kind of brand-new main beam structure pattern, and the componentization showing " Area Decomposition, width are discrete, supporting subregion, module are assembled " builds concept, has filled up a blank of bridge construction technology;
Frame-type three body steel girder is by lateral stressed main decomposition to gooseneck, and girder height controls primarily of longitudinal stress, has broken away from the impact of transverse width;
It is stressed that four point elastic support that four rope faces are formed significantly reduce gooseneck, gooseneck height reduction, and spacing widens, and the longitudinal stress of limit steel girder is also optimized further simultaneously;
Middle steel girder is supported on gooseneck, make use of the affluence of the supporting capacity that gooseneck causes because of structure and the requirement of rigidity degree, and bridge track increases, function upgrading, technology, economic indicator optimization;
The girder size of cable stayed bridge four rope face three body steel and be arranged in vertical, horizontal and all controlled, structural advantage is played, and inferior position is limited, and significantly reduces with material;
Componentization builds concept and modularized design mode achieves limit, middle steel girder, the independence lifting of gooseneck and the substep formation of overall steel girder, and lift heavy decomposes, and constructs convenient.
