Description
Technical field:
The present invention relates to a kind of suspension cable anchor device, especially a kind of cable stayed bridge that is used for adopts parallel rope face, the less stayed-cable anchor plate type anchoring structure of stayed-cable bridge cable tower in king-post cross section.
Background technology:
The hollow variable cross-section king-post of the general employing of the king-post of large span stayed-cable bridge at present, anchoring has anchoring systems such as ring orientation prestress, steel anchor box and steel anchor beam on the oblique tensile tower of technology comparative maturity.The ring orientation prestress anchoring structure is the annular prestressed bundle of plane of arrangement in the tower wall, the internal force that the external force that produces with prestressing tendon comes the balance suspension cable to produce in the tower wall.Steel anchor box and steel anchor beam anchoring structure mainly are to resist the horizontal component that suspension cable produces by steel anchor box or steel anchor beam are set in tower, and king-post mainly bears vertical force component, and the steel anchor box anchor structure that has also needs to resist horizontal force by horizontal prestressing force is set.But these anchor types all require the Tower Column of A Cable Stayed Bridge column section bigger, can't realize in less king-post cross section.And, on the reliable basis of structural safety, consider convenient construction, the reduction cost and handsome in appearance of cable stayed bridge some medium and small striding in the cable stayed bridge design of footpath, the king-post design tends to select less sectional dimension.At present, still there is not a kind of anchoring that can satisfy above-mentioned Sarasota instructions for use.
Summary of the invention:
The invention provides a kind of stayed-cable anchor plate type anchoring structure of stayed-cable bridge cable tower, it is simple in structure, and power transmission is clear and definite, and volume is little, be suitable for the less Cable-stayed Bridge Pylon in king-post cross section and use, easy construction, cost is low, structural safety is reliable, and profile is succinctly attractive in appearance, has solved problems of the prior art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: it comprises the steel anchor slab that is embedded in concrete king-post inside, and lateral symmetry is provided with diaphragm in the two sides of steel anchor slab, vertically is arranged with a vertical clapboard in the centre position, two sides; Be provided with a base plate in the bottom of steel anchor slab, on the upper surface of the two sides of steel anchor slab, base plate, vertically be arranged with stiffening rib, on the steel anchor slab of vertical clapboard both sides, be arranged with some with the vertically disposed PBL shear connector of steel anchor slab; Be fixed with one respectively at the two ends of steel anchor slab and stretch out the anchoring otic placode in the king-post outside, the anchoring otic placode is provided with pin-and-hole, be respectively equipped with a side plate parallel at steel anchor slab two ends with anchoring otic placode junction, on the anchoring otic placode, be fixed with an end horizontal stiffener relative with the diaphragm position with vertical clapboard.
Anchoring otic placode both sides at the pin-and-hole place are respectively equipped with stiffening plate.
Be provided with two-layer diaphragm up and down in the two sides of steel anchor slab lateral symmetry.
Vertical symmetrically arranged stiffening rib is two groups on the upper surface of the two sides of steel anchor slab, base plate, and two groups of stiffening ribs are symmetricly set on the vertical clapboard both sides.
The present invention is simple in structure, power transmission is clear and definite, volume is little, anchoring otic placode and steel anchor slab connect as one, pass through PBL shear connector and diaphragm with king-post, vertical clapboard, base plate, stiffening rib connects, the anchoring otic placode passes to the anchorage zone with stay cable force, the steel anchor slab mainly bears the horizontal component of suspension cable, the PBL shear connector, diaphragm, vertical clapboard, base plate and stiffening rib link together steel anchor slab and concrete king-post, bear the vertical force component and the part of horizontal component of suspension cable jointly, whole anchor structure is except the anchoring otic placode is exposed at the concrete king-post, and remainder all is embedded in concrete king-post inside, and structural safety is reliable, profile is succinctly attractive in appearance, easy construction, cost is low, is suitable for the less Cable-stayed Bridge Pylon in king-post cross section and uses.
