Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of drag-line bridge tower anchoring structure, and structure is simple, power transmission is clear and definite, and integral rigidity is high.
Drag-line bridge tower anchoring structure of the present utility model, comprise two layback plates and the anchoring unit between two layback plates, described layback plate is anchored at the relative inner of two anchorage zones on Sarasota respectively by shear connector, described anchoring unit comprises two bearing plates and an anchor plate, described two bearing plate Parallel Symmetrics are in drag-line both sides, and two ends be connected with two layback plates respectively, described anchor plate is perpendicular to bearing plate and be connected with two bearing plate tops, and described anchor plate is provided with the through hole passed for drag-line.
Further, described anchoring unit also comprises multiple stiffener, and described stiffener passes perpendicularly through two bearing plates and is connected with anchor plate.
Further, described anchoring unit also comprises cable spiral, and described cable spiral is between two bearing plates and be coaxially connected on anchor plate with through hole.
Further, respectively there is a prestress steel twist spool the upper and lower both sides of described anchoring unit, described prestress steel twist spool, two ends be each passed through both sides layback plate and extend in Sarasota and near Sarasota outer face.
The beneficial effects of the utility model: drag-line bridge tower anchoring structure of the present utility model, comprise two layback plates and the anchoring unit between two layback plates, described layback plate is anchored at the relative inner of two anchorage zones on Sarasota respectively by shear connector, described anchoring unit comprises two bearing plates and an anchor plate, described two bearing plate Parallel Symmetrics are in drag-line both sides, and two ends be connected with two layback plates respectively, described anchor plate is perpendicular to bearing plate and be connected with two bearing plate tops, and described anchor plate is provided with the through hole passed for drag-line.The pulling force of drag-line passes to Sarasota by anchor plate, bearing plate, layback plate, and power transmission is clear and definite, and structure is simple, and integral rigidity is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is schematic side view of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail: the drag-line bridge tower anchoring structure of the present embodiment, comprise two layback plates 1,2 and the anchoring unit 3 between two layback plates 1,2, described layback plate 1,2 is anchored at the relative inner of two anchorage zones 101,201 on Sarasota respectively by shear connector 4, wherein shear connector can be rivet, crab-bolt etc., and the concrete quantity of shear connector is determined according to load.Anchoring unit 3 from top to bottom totally two arranges, and two row anchoring unit are symmetrical arranged, for the drag-line 7 of anchoring Sarasota both sides.Each anchoring unit 3 comprises two bearing plates, 301,302 and anchor plate 303, described two bearing plate 301,302 Parallel Symmetrics are in drag-line 7 both sides, and two ends be connected with two layback plates respectively, described anchor plate 303 is perpendicular to bearing plate and be connected with two bearing plate tops, and described anchor plate 303 is provided with the through hole 304 passed for drag-line.Drag-line top is passed through and passes to be anchored at anchor plate 303 after 304 between two bearing plates 301,302, and this anchor structure is steel construction piece, welds between adjacent steel structural member, and make anchor arrangement in aggregates, structure is simple.The vertical force component of drag-line passes to layback plate 1,2 by anchor plate 303 and two bearing plates 301,302, concrete pylon is passed to again by the shear connector on layback plate, finally born by Sarasota, the horizontal component of Sarasota both sides drag-line realizes balance by corresponding anchoring unit.As can be seen here, this anchoring mechanism, power transmission is clear and definite, drag-line and Sarasota anchoring rigidity high.
As the further improvement of technique scheme, described anchoring unit 3 also comprises multiple stiffener 305, described stiffener 305 passes perpendicularly through two bearing plates 301,302 and is connected with anchor plate 303, stiffener 305 improves the intensity of bearing plate 301,302 and anchor plate 303, improves the ability of the opposing drag-line pulling force of anchoring unit 3 on the whole.
As the further improvement of technique scheme, described anchoring unit 3 also comprises cable spiral 306, described cable spiral 306 is between two bearing plates 301,302 and be coaxially connected on anchor plate 303 with through hole 304, and guide effect is played, constructability in cable spiral 306 pairs of drag-line tops.
As the further improvement of technique scheme, respectively there is a prestress steel twist spool 5,6 described anchoring unit about 3 both sides, and the two ends of described prestress steel twist spool 5,6 are each passed through the layback plate 1,2 of both sides and extend in Sarasota and close Sarasota outer face.Prestress steel twist spool 5,6 improves between Sarasota two anchorage zone on the whole
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
