Technical field
The present invention relates to inhaul cable anchorage structure, and in particular to the inhaul cable anchorage structure in a kind of steel box-girder.
Background technology
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 that drag-line is anchored on beam.The above-mentioned type bridge is in construction, because across footpath is larger, girder generally use steel
Box-beam structure, therefore it is most commonly seen to be arranged at the inhaul cable anchorage structure on steel box-girder.Due to Large Span Bridges girder deck-molding compared with
Height, anchoring space of the drag-line on steel box-girder are also more spacious.Further, since the reason that the structure scale of construction is larger, Large Span Bridges
The space angle of cut of the drag-line relative to main beam section structure centre line on cross-bridges it is smaller, this also causes the drawing of the above-mentioned type bridge
Rope anchor structure is designed to relatively simple.
But when setting inhaul cable anchorage structure in the less Urban Landscape Bridge of the scale of construction, due to existing, girder is short, draws
Rigging has the factors such as the complex space angle of cut, and anchoring of the drag-line on girder becomes sufficiently complex, it is difficult to reference in Large Span Bridges
In inhaul cable anchorage structure be designed, it is necessary to according to actual conditions design drag-line anchor point on beam position, drag-line is in steel
Anchoring structure form, anchoring structure installation method and drag-line installation, method for stretching in box beam etc..
The content of the invention

On be fixed with drag-line anchor tube, is provided with drag-line in the drag-line anchor tube.
Preferably, first shear resisting board and the second shear resisting board are fixed together by full penetration.
Preferably, angulation is acute angle between first shear resisting board and the second shear resisting board.
Preferably, first shear resisting board, the second shear resisting board with corresponding drag-line centerline parallel.
Preferably, the bearing plate is vertically fixed on the first shear resisting board and the second shear resisting board.
Preferably, the bearing plate and corresponding drag-line central axis.
Preferably, the parallel-plate is vertically fixed on bearing plate.
Beneficial effects of the present invention：
Inhaul cable anchorage structure in a kind of steel box-girder provided by the present invention is in the anchor point position of main beam structure both sides drag-line
Put with different vertical elevations, it is ensured that drag-line will not constructively interfere, and drag-line can be installed, together simultaneously
Shi Zhangla is dismantled simultaneously so that Cable forces are more uniform, are advantageous to safeguard integrally-built stability；Adopted between shear resisting board
The rigidity in anchor-hold region can be increased substantially with connecting structure, reduces the local deformation in anchor-hold area；Using fine melt
Welding can ensure integrally-built stability thoroughly, the problems such as avoiding the occurrence of local fatigue.
Design, concrete structure and the caused technique effect of the present invention are described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
