Abstract
The utility model relates to a railway continuous steel box girder. In the form construction process of a steel truss girder, the varieties of rod pieces are great, the installation period is long, and the construction progress is low. The construction of a bridge girder which spans an expressway or a high-speed railway is bound to influence the normal running of the underneath railway or the underneath expressway. A closed rectangular cavity is formed by a top plate, a bottom plate and two side webs, the two sides of the top plate extend to form flanges, and the continuous steel box girder is a continuous steel box girder which is in the same height throughout the bridge; plate stiffened ribs are arranged on the inner sides of the webs, and T-shaped stiffened ribs are arranged on the inner side of the bottom plate; T-shaped stiffened ribs are arranged on the inner side of the top plate, and big longitudinal ribs are arranged in the positions corresponding to rails, of the top plate; a plurality of horizontal partition plates are arranged on the inner circumference of a hollow cavity of the continuous steel box girder; horizontal longitudinal ribs and vertical longitudinal ribs are arranged on the horizontal partition plates, which are positioned at support points, in the continuous steel box girder. The railway continuous steel box girder adopting a box type cross section has the advantages of simple structural form, great integrality, high construction speed, high safety coefficient and low construction difficulty.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to a kind of railway Steel Continuous Box beam.
Background technology
Traditional girder steel adopts steel truss girder form mostly, in work progress, by installation member Cheng Qiao.In girder steel work progress, rod member is of a great variety, and rod member installation period is long, and construction speed is slow.For the bridge of acrossing highway, high-speed railway, certainly will affect the normal operation of descending railway or highway.Even change construction method, also the rod member kind due to steel truss girder is many, bolt quantity is large, can not effectively prevent that falling object from falling to affecting the safe operation of descending on-highway motor vehicle or train.Under this background, adopt a kind of safer type of bridge of succinct, easy construction, construction of constructing particularly necessary.
Summary of the invention
The purpose of this utility model is to provide the railway Steel Continuous Box beam that a kind of bridge member form is simple, type is few, in the situation that crossing over existing railway or highway, also can complete safely, fast construction.
The technical scheme that the utility model adopts is:
A railway Steel Continuous Box beam, comprises the web of top board, base plate and both sides, and top board both sides are extended with the edge of a wing, it is characterized in that:
Described Steel Continuous Box beam is the contour Steel Continuous Box beam of full-bridge, and the web of its top board, base plate and both sides forms closed rectangular enclosure.
Described web inner side is provided with web longitudinal stiffener, is plate shape stiffening rib;
Described base plate inner side is provided with base plate longitudinal stiffener, is T-shaped stiffening rib;
Described top board inner side is provided with top board longitudinal stiffener, is T-shaped stiffening rib; The top board inner side of the position corresponding with track is provided with large vertical rib, is T-shaped stiffening rib.
In the hollow cavity of described Steel Continuous Box beam, ring arranges multiple tracks diaphragm week.
The Steel Continuous Box beam at fulcrum place, is provided with the longitudinal stiffener on level and vertical direction on its inner diaphragm.
The utlity model has following advantage:
1) section form is simple:
Adopt closed box-type section, the steel truss girder that structure is more traditional, profile is smooth simple.
2) adopt box-type section, the good integrity of structure:
Box-type section is compared with other type cross section, and laterally torsional rigidity is large.And transverse stiffener is set at a certain distance, has effectively strengthened the rigidity of structure, the more traditional girder steel of globality is good.
3) speed of application is fast:
Because full-bridge adopts unified profile structure, the surfacing of case beam, can accelerate the pushing tow speed of girder steel, completes fast construction.
4) construction safety coefficient is high:
Because profile is smooth, full-bridge adopts welding manner to connect, and bolt and other scattered member are seldom, during construction, less to descending railway or highway interference, can be applicable to different circuit grade separation situations, are particularly useful for across bridges such as speedway and high-speed railways.
5) difficulty of construction is little:
Traditional steel truss girder, element type is many, and work progress is loaded down with trivial details, need carry out in building site rod member assembled in advance, and assembled in advance without rod member of steel box girder, has reduced difficulty of construction, has accelerated the progress of structure construction.
