Description
Technical field
The present invention relates to bridge, the large span box girder with corrugated steel webs bridge for being specifically for use in left and right width while building.
Background technology
Corrugated steel web plate composite box girder structure is exactly that the web of concrete box girder, waveform are instead of by the higher steel of intensity
By shearing key connection between steel web and roof and floor, the combining structure that steel and concrete each play its speciality is formd.
The deadweight of bridge superstructure can be greatly lowered using Wavelike steel webplate, this is in the poor area of geological conditions, economy effect
Benefit is particularly evident.Meanwhile replace concrete web with the higher Wavelike steel webplate of shearing strength, can targetedly solve greatly across
Spend continuous rigid frame (continuous beam) bridge cracking in webs and due to beam body downwarp is excessive caused by cracking in webs the problem of, thus this knot
Structure has broad application prospects.
Current domestic highway is mostly two-way four-lane or two-way six-lane, and width of subgrade is 24.5~34.5m, bridge
Structure is set by double width, and the wide about 12~17m of single width bridge, box beam section is mostly single box single chamber structure.With the increasing of span and deck-molding
Add, the antitorque and anti-distortion performance of box girder with corrugated steel webs turns into the key factor of control design case, after span is more than 160m
These effects are particularly evident.This not only can increase the unbalance loading effect of mobile load, increase the load effect of box girder bridge, it is also possible to can draw
Play the overall collapse of box-beam structure.Thus provide it is a kind of it is new, be remarkably improved that box girder with corrugated steel webs is antitorque and anti-distortion
The structural form of performance has and its important meaning.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of more chamber box girder with corrugated steel webs constructions of combined type, with aobvious
Write the antitorque and anti-distortion performance for improving box girder with corrugated steel webs.
The technical solution adopted for the present invention to solve the technical problems is as follows：
The combined type more chamber box girder with corrugated steel webs construction of the present invention, including by concrete roof, concrete floor and
Single chamber box girder with corrugated steel webs that both sides Wavelike steel webplate is formed, it is characterized in that：Single chamber box girder with corrugated steel webs
Quantity is at least two, laterally parallel to set, and attachment structure is set between adjacent two single chamber box girder with corrugated steel webs, by each list
Chamber box girder with corrugated steel webs connects as one, and forms more chamber box girder with corrugated steel webs.
The invention has the advantages that structure innovation, reasonable stress, structure integral rigidity is big, can significantly improve waveform
Steel web box girder is antitorque and anti-distortion performance, for corrugated steel web plate composite box girder structure is applied into more large span (more than 160m)
Bridge provide technical support.
