Description
Technical field
This utility model relates to bridge, is applied to large-span continuous rigid (beam) box girder bridge composite wave-shape steel particularly to one
Web box girder.
Background technology
Wavelike steel webplate-concrete combined box beam bridge has preferable economic advantages, duration than concrete web box girder bridge
Shorter advantage and the advantage of convenient construction.And span is the biggest, advantage is the most obvious, but due to by steel Buckling of Web stability
Controlling impact, the span of Wavelike steel webplate-concrete combined box beam bridge is extremely limited, current maximum span be only
164m, and the maximum span of concrete web box girder bridge is more than 300 meters.Wavelike steel webplate-concrete combined box beam bridge across
Degree range is extremely limited, and superiority can not be not fully exerted.
The overall mechanical characteristic of Wavelike steel webplate-concrete combined box beam bridge and the mechanical characteristic base of concrete web box beam
This is similar, after rational deck-molding, Wavelike steel webplate form and thickness, roof and floor thickness and longitudinal steel bundle are set, and waveform steel
The overall bending resistance of web box girder continuous rigid frame (beam) bridge and shearing strength all can meet requirement, the only local such as steel web structure
The force way of part is different, but the deadweight of box girder with corrugated steel webs bridge is lighter, so, if it is stable to solve Wavelike steel webplate flexing
Sex chromosome mosaicism, Long Span Continuous Rigid-Frame Structure (beam) box girder with corrugated steel webs bridge should can reach bigger by relatively concrete web box girder bridge
Span.
Owing to by manufacture, fracture toughness and fatigue problem, the thickness of steel web is usually no more than 30mm.China's industry mark
In accurate " composite bridge Wavelike steel webplate " (JT/T 784-2010), the maximum gauge of suggestion Wavelike steel webplate is also
30mm。
Utility model content
Technical problem to be solved in the utility model is to provide a kind of composite wave-shape steel web box girder, to greatly improve
The Limit Span of Wavelike steel webplate, enables steel-mixed combination box beam bridge more fully to make the most of the advantage.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Composite wave-shape steel web box girder of the present utility model, by top board, base plate and left side Wavelike steel webplate, right side waveform steel
Web is constituted, and it is characterized in that: described left side Wavelike steel webplate, right side Wavelike steel webplate include outside corrugated sheet steel, interior side waveform
Steel plate, outside corrugated sheet steel, inner side corrugated sheet steel are connected as one by connector, constitute composite wave-shape steel web.
The beneficial effects of the utility model are, structure innovation, reasonable stress, and power transmission is clear and definite, can give full play to the strength of materials,
Drastically increase the Limit Span of Wavelike steel webplate-concrete combined box beam bridge, make Wavelike steel webplate-concrete combined box beam
The Limit Span of bridge brings up to more than 300 meters from less than 200 meters, more fully plays Wavelike steel webplate-concrete combined box
The advantage of beam bridge.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is the section structure schematic diagram of this utility model composite wave-shape steel web box girder；
Fig. 2 is the profile of line A-A along Fig. 1；
Component shown in figure and corresponding labelling: top board 10, base plate 11, left side Wavelike steel webplate 12, right side waveform steel abdomen
Corrugated sheet steel 131, inner side corrugated sheet steel 132, flat segments L in plate 13, outside1, waveform segment L2, connector 14.
Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
With reference to Fig. 1, composite wave-shape steel web box girder of the present utility model, by top board 10, base plate 11 and left side waveform steel abdomen
Plate 12, right side Wavelike steel webplate 13 are constituted, with reference to Fig. 2, outside described left side Wavelike steel webplate 12, right side Wavelike steel webplate 13 include
Side waveform steel plate 131, inner side corrugated sheet steel 132, outside corrugated sheet steel 131, inner side corrugated sheet steel 132 are connected by connector 14
It is integrated, constitutes composite wave-shape steel web.
In the case of not increasing web gross thickness, composite wave-shape steel web can be greatly enhanced steel web both direction
Rigidity, be greatly enhanced the buckling stability energy of web, thus increase substantially Wavelike steel webplate-concrete combined box beam bridge
Limit Span, this greatly expands the span range of Wavelike steel webplate-concrete combined structure box girder bridge.
When using the Wavelike steel webplate-concrete combined box beam bridge of more large span, the warp of steel-mixed composite bridge
Advantage and the advantage of convenient construction that Ji advantage, duration are shorter can be obtained by more fully playing.
With reference to Fig. 2, described outside corrugated sheet steel 131, inner side corrugated sheet steel 132 have separately in its longitudinal direction
Waveform segment L2, adjacent two waveform segment L2Between be flat segments L1, connector 14 is arranged at flat segments L1On.Described outer side waveform steel
Plate 131, the waveform segment L of inner side corrugated sheet steel 1322, flat segments L1Corresponding, outside corrugated sheet steel 131, inner side corrugated sheet steel 132
Waveform segment L2On direction across bridge direction respectively outside box beam, box beam internal protrusion.Generally, described connector 14 is high-strength spiral shell
Bolt assembly, in flat segments L1On be spaced along short transverse and length direction and to arrange.
With reference to Fig. 1, outside corrugated sheet steel 131, inner side corrugated sheet steel 132 can carry out the bending machining of steel plate in factory, and
Rust prevention by applying liquid material layer, is then connected by high-strength bolt assembly, forms composite wave-shape steel web.At the construction field (site), lifting is installed multiple
Close Wavelike steel webplate, after colligation complete roof and floor reinforcing bar, pour roof and floor concrete, form steel-mixed combined box beam.
The above principle more of the present utility model that simply explain through diagrams, is not intended to be confined to this utility model
Shown in and described concrete structure and the scope of application in, therefore every corresponding amendment being likely utilized and equivalent, all
Belong to the apllied the scope of the claims of this utility model.
