Description
Technical field
The present invention relates to a kind of partial cable-stayed bridge sub-wire tube type rope saddle.Belong to bridge construction part technical field.
Background technology
In partial cable-stayed bridge, steel strand stay cable, through after cable saddle pre-buried in bridge tower, is anchored on the case beam of bridge tower both sides.Suspension cable is in construction and operation process, not etc., therefore the Suo Li of the suspension cable of cable saddle both sides is not by force unbalance, therefore needs to take measures for Sarasota both sides load, prevent the slippage in cable saddle under the effect of uneven Suo Li of the steel strand in suspension cable, to ensure the safety of bridge.Secondly, for ensureing to change suspension cable under the prerequisite of uninterrupted traffic, need to make each steel strand in suspension cable can realize single substituting.
The Authorization Notice No. of applicant is CN20095512Y, name is called " partial cable-stayed bridge binding type steel pipe assembly welding formula divides fiber tube cable saddle " patent of invention, the single of each steel strand in suspension cable can be realized substitute, but the resistant slide requirement of steel strand in cable saddle can not be met.The Authorization Notice No. of applicant is CN203065966U, name is called that " partial cable-stayed bridge resisting the slippage of Cable Stayed Steel twisted wire divides fiber tube cable saddle " can meet the resistant slide of steel strand in cable saddle and to require and the single of steel strand is substituted, but manufacturing cost is higher.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of can suspension cable build and out-of-balance force, the again steel strand that can realize in suspension cable that resist Sarasota both sides during operation can singlely change and manufacturing cost lower the partial cable-stayed bridge of single replacing steel strand can divide fiber tube cable saddle.
The object of the present invention is achieved like this: a kind ofly the partial cable-stayed bridge of single replacing steel strand can divide fiber tube cable saddle, comprises anchor plate, reinforcing rib, steel pipe bundle and stirrup, it is characterized in that:
Described steel pipe bundle is made up of N root polygonal steel pipe and M root calking rod iron, and calking rod iron is filled in the gap between outermost layer polygonal steel pipe, and wherein, N is identical with steel strand radical in suspension cable, is the natural number of >=1; M is the natural number of >=0,
The cross section cavity shape of described polygonal steel pipe is equilateral or unequal-sided polygon, number >=3, polygonal limit,
The angle of two adjacent edges in polygonal below of the cross section inner chamber of described polygonal steel pipe is acute angle,
Fixed by spot welding between each polygonal steel pipe within the outermost layer of described steel pipe bundle,
Utilize gas shielded arc welding integrally welded in gap between outermost adjacent two polygonal steel pipes of described steel pipe bundle and in the gap of outermost layer polygonal steel pipe and calking rod iron,
The steel pipe bundle after assembly welding wrapped by described stirrup, and integrally welded with it.
The present invention the partial cable-stayed bridge of single replacing steel strand can divide fiber tube cable saddle, the angle arc transition of two adjacent edges in polygonal below of the cross section inner chamber of described polygonal steel pipe.
The invention has the beneficial effects as follows:
The sub-wire tube type rope saddle of said structure is adopted to be embedded in Sarasota, after the N root polygonal steel pipe of the N root steel strand in suspension cable separately independently through the correspondence of point fiber tube cable saddle, stretch-draw anchor on the case beam of bridge tower both sides.Because the angle of two adjacent edges in polygonal below of the cross section inner chamber of polygonal steel pipe is acute angle, steel strand contact (Fig. 5) with two scarves of polygon steel inside pipe wall, therefore compared with round steel pipe, friction factor between steel strand and polygonal steel pipe improves greatly, makes the frictional force of steel strand in cable saddle be enough to resist the out-of-balance force of cable saddle both sides; Therefore, the steel strand of cable saddle both sides prevent its slippage without the need to taking other consolidation measure, thus realize the single of each steel strand in suspension cable and substitute.
Within the outermost layer of steel pipe bundle each polygonal steel pipe only spot welding fix, steel pipe inner wall can not burn through; Use gas shielded arc welding firm welding in the gap of outermost layer polygonal steel pipe and calking rod iron, after weld seam cooling, each for internal layer polygonal steel pipe is held with a firm grip by its shrinkage stress; Steel pipe bundle external welding stirrup, guarantees that the structural entity after assembly welding is firm.When cable saddle installs location in Sarasota simultaneously, spacer bars can be welded with stirrup, avoid spacer bars and cable saddle steel pipe directly to weld and make steel pipe burn through and cause steel strand to penetrate the problem of steel pipe difficulty.
Whole cable saddle is welded construction, and processing, manufacture and installation are very convenient.Therefore manufacturing cost is lower.
