It is provided with the structure anchoring drag-line on beam.The above-mentioned type bridge is in construction, and due to relatively big across footpath, girder generally uses steel
Box-beam structure, the inhaul cable anchorage structure being therefore arranged on steel box-girder is most commonly seen.Due to Large Span Bridges girder deck-molding relatively
Height, drag-line anchoring space on steel box-girder is the most spacious.Additionally, due to the reason that the structure scale of construction is bigger, Large Span Bridges
Drag-line less relative to the space angle of cut of main beam section structure centre line on cross-bridges, this also makes drawing of the above-mentioned type bridge
Rope anchor structure is designed to relatively simple.
But when the Urban Landscape Bridge less in the scale of construction arranges inhaul cable anchorage structure, owing to having that girder is short, drawing
Rigging has the factors such as the complex space angle of cut, and drag-line anchoring on girder becomes sufficiently complex, it is difficult to reference at Large Span Bridges
In inhaul cable anchorage structure be designed, need according to practical situation design drag-line position of anchor point on beam, drag-line is at steel
Anchoring structure form, anchoring structure installation method and drag-line installation, method for stretching etc. in box beam.
Utility model content
Because the drawbacks described above of prior art, this utility model provides the inhaul cable anchorage structure in a kind of steel box-girder, energy
The drag-line existing for prior art is enough effectively overcome constructively to be susceptible to interference, Cable forces inequality, drag-line installation inconvenience
And local, the anchor-hold district defect such as the most yielding.
For achieving the above object, this utility model provides the inhaul cable anchorage structure in a kind of steel box-girder, resists including first
Shear and the second shear resisting board, described first shear resisting board and the second shear resisting board be fixed together by welding, described first shear resisting board
Be respectively and fixedly provided with bearing plate on the second shear resisting board, described bearing plate is provided with installing hole, and described bearing plate homonymy two ends are the most fixing
Having parallel-plate, be fixed with box beam base plate bottom described first shear resisting board and the second shear resisting board, described first shear resisting board and second resists
Shear top is fixed with box beam top board, is respectively and fixedly provided with box girder web, described peace outside described first shear resisting board and the second shear resisting board
Dress is fixed with drag-line anchor tube on hole, is provided with drag-line in described drag-line anchor tube.
Preferably, described first shear resisting board and the second shear resisting board are fixed together by full penetration.
Preferably, between described first shear resisting board and the second shear resisting board, angulation is acute angle.
Preferably, described first shear resisting board, the second shear resisting board all with corresponding drag-line centerline parallel.
Preferably, described bearing plate is vertically fixed on the first shear resisting board and the second shear resisting board.
Preferably, described bearing plate and corresponding drag-line central axis.
Preferably, described parallel-plate is vertically fixed on bearing plate.
The beneficial effects of the utility model:
Inhaul cable anchorage structure in a kind of steel box-girder provided by the utility model is in the anchoring of main beam structure both sides drag-line
Point position has different vertical elevations, it is ensured that drag-line constructively will not interfere, and drag-line can be pacified simultaneously
Dress, simultaneous tension, dismantle so that Cable forces is more uniform, is conducive to safeguarding integrally-built stability simultaneously；Shear resisting board it
Between use connecting structure can increase substantially the rigidity in anchor-hold region, reduce the local deformation in anchor-hold district；Use
Full penetration ensure that integrally-built stability, it is to avoid the problems such as local fatigue occurs.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is made furtherly
Bright, to be fully understood from the purpose of this utility model, feature and effect.
