Abstract
The utility model discloses a saddle weight steel box structure of a railway steel truss cable-stayed bridge. The structure is simple, and the problem of placing saddle weights is solved. A plurality of steel boxes (10) are arranged in a direction of a transverse bridge between two cross beams or transverse ribs (12) below a steel bridge deck slab, saddle weights (11) are arranged in the steel boxes (10), two longitudinal side plates (N1), two transverse side plates (N2) and a base plate (N3) are welded to form each steel box (10), and a longitudinal stiffening diaphragm (N4) and a transverse stiffening diaphragm (N5), which are welded with the steel box into a whole, are arranged inside the steel box.
Description
Technical field
The utility model relates to steel purlin cable stayed bridge, particularly the ballast steel box structure of a kind of steel purlin cable stayed bridge.
Background technology
Modern cable stayed bridge from the seventies in last century since China begins to build, obtained to develop rapidly over 30 years, so far seats built up to a hundred.And the development of Railway Cable-stayed Bridge is very slow.In recent years, paces have been accelerated in railway construction, have proposed Cable-stayed Bridge Scheme in the bridge project study of some ew lines, and particularly carrying out of Beijing-Shanghai High-Speed Railway previous work deeply carried out the design studies work of Railway Cable-stayed Bridge.The Railway Cable-stayed Bridge research span of carrying out has at present covered the scope from more than 200 meters to more than 600 meters, and the carrying out of these research work is for construction and the development of Railway Cable-stayed Bridge provides good theoretical foundation and the technological reserve of necessity.Up to now, the Railway Cable-stayed Bridge of building up in the world is few in number.The Federal Republic of Yugoslavia Belgrade city savart river bridge that built up in 1980 is heavily loaded Railway Cable-stayed Bridge, span 250m; Japan the 2,000 bent Chuan Qiao is the railway low-pylon cable-stayed bridge, 134 meters of main spans.The maximum span of the domestic highway and railway bi-purpose cable-stayed bridge that has built up is 504 meters (System for Wuhan Tianxingzhou Yangtze River Bridges, four-track line adds the six-lane highway double bridge), the Tongling Yangtze Bridge main span of building reaches 630 meters (four-track line adds the six-lane highway double bridge), the maximum span of the external highway and railway bi-purpose cable-stayed bridge that has built up is Denmark's Oresund bridge, and main span is 490 meters.
Larger negative reaction of support appears in cable stayed bridge under the operation state at the auxiliary pier place.The conventional method that solves the auxiliary pier negative reaction of support has two kinds: the one, and guy system is set connects main truss and pier shaft; The 2nd, add ballast.Conventional cable stayed bridge employing applies saddle weight or end bay and adopts concrete beam to come ballast in steel case beam inner space.As adopt the former steel box girder of cable stayed bridge inner space, steel purlin limited, as adopting the latter's beam section concrete and steel bi-material, complex structural designs are arranged.The applicant discloses a kind of steel purlin cable stayed bridge ballast structure in the utility application that proposes on the same day, ballast is by upper ballast concrete and press down high density concrete and consist of, upper ballast concrete is arranged at steel bridge deck direction across bridge both sides, and forms a fixed connection by WELDING STUDS and steel bridge deck; Press down high density concrete and be positioned under the steel bridge deck, in the steel case of packing into, the steel case is fixedly connected with the formed steel construction that is arranged between crossbeam or cross rib.This structural texture is simple, can provide than large space, and is applied widely, and design and construction are simple, because the space is larger, the ballast material can adopt the little ordinary concrete of specific pressure high density concrete unit weight, is conducive to reduce construction costs.
The utility model content
Technical problem to be solved in the utility model provides a kind of steel purlin cable stayed bridge ballast steel box structure, and is simple in structure, effectively solves the saddle weight Placement Problems.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Railway Steel Truss cable stayed bridge ballast steel box structure of the present utility model, it is characterized in that: it is included in a plurality of steel casees that direction across bridge arranges between two crossbeams under the steel bridge deck or the cross rib, place saddle weight in the steel case, the steel case is welded by two longitudinal side plates, two blocks of horizontal side plates and base plate, is laid with the vertical stiffening diaphragm, the lateral stiffening dividing plate that are welded as a whole with it in it.
The beneficial effects of the utility model are, and are simple in structure, solve well Railway Steel Truss cable stayed bridge saddle weight Placement Problems.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the structural representation of the utility model Railway Steel Truss cable stayed bridge ballast steel box structure form;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Component shown in the figure, toponym and corresponding mark: ballast steel case 10, saddle weight 11, crossbeam or cross rib 12, i shaped steel member 13, high-strength bolt 14, high-strength bolt 15, longitudinal side plate N1, horizontal side plate N2, base plate N3, vertical stiffening diaphragm N4, lateral stiffening dividing plate N5.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, Railway Steel Truss cable stayed bridge ballast steel box structure of the present utility model, it is included in a plurality of steel casees 10 that direction across bridge arranges between two crossbeams under the steel bridge deck or the cross rib 12, steel case 10 interior placement saddle weights 11.Steel case 10 is welded by two longitudinal side plate N1, two horizontal side plate N2 and base plate N3, is laid with the vertical stiffening diaphragm N4, the lateral stiffening dividing plate N5 that are welded as a whole with it in it.Lay i shaped steel member 13 along the direction across bridge interval between described two crossbeams or the cross rib 12, the two ends of i shaped steel member 13 are connected with crossbeam or cross rib 12 by high-strength bolt 15, and steel case 10 is fixed on the i shaped steel member 13 by high-strength bolt 14.
Some principles of the above the utility model Railway Steel Truss cable stayed bridge ballast steel box structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
