Description
Technical field
The present invention relates to inhaul cable anchorage structure, be specifically related to the inhaul cable anchorage structure in a kind of steel box-girder.
Background technology
The bridge using drag-line is usually Large Span Bridges, such as: cable-stayed bridge, suspension bridge, bowstring arch bridge etc., in these bridges
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.
Summary of the invention
Because the drawbacks described above of prior art, the present invention provides the inhaul cable anchorage structure in a kind of steel box-girder, it is possible to have
Effect overcomes the drag-line existing for prior art to be constructively susceptible to interfere, Cable forces is uneven, drag-line installs inconvenience and
The defects such as local, anchor-hold district is yielding.
For achieving the above object, the invention provides the inhaul cable anchorage structure in a kind of steel box-girder, including the first shear resisting board
