Description
Technical field
The utility model relates to a kind of cable stayed bridge anchor case anchor structure, refers to specifically that a kind of cable stayed bridge is slided first to consolidate afterwards type combination steel anchor box anchor device.
Background technology
The inhaul cable anchorage structure of Sarasota is with the concentration of local power safety of a suspension cable, the Transmit evenly important stress structure to king-post.For striding greatly cable stayed bridge, mainly contain three kinds of anchorage styles: the tooth piece adds tower wall prestress anchoraging, steel anchor box anchoring and the anchoring of steel anchor beam (generally not applying prestressing force in the tower wall when steel anchor box and the anchoring of steel anchor beam)." U " shape prestressing tendon or " well " font prestressing tendon to drawing generally adopted in the anchoring of tooth piece Prestressing, guarantee that by applying prestressing force the concrete towers wall does not ftracture, this mode anchoring cost is low, the later maintenance workload is little, and the jack tension space is large in the tower, but the anchoring tooth plate is many in the tower, it is loaded down with trivial details to construct, the difficult control of suspension cable anchor tube positioning accuracy and quality, reinforcing bar is intensive in drag-line and the prestressing force tooth plate, and the closely knit difficulty of concrete vibrating is larger; The bend radius of ring prestressed steel bundle is less, and loss of prestress is large, and its bundle number is more, and ground tackle notch place cuts off that reinforcing bar is more in length and breadth, and resistance is unfavorable; And all operation needs on-the-spot work high above the ground, and the integral construction quality is difficult for guaranteeing.And steel anchor box is made in factory, and the position of anchor point and the angle of anchor tube are controlled easily; Shortcoming is that the drag-line horizontal force must be by tower wall and steel anchor box shared, steel anchor box has stoped again the contraction of tower wall, the horizontal force that causes the tower wall to be shared is enough to make concrete cracking, if adopt prestressing force to prevent tower wall cracking, then steel anchor box has stoped again prestressed applying, and steel anchor box is only born the fraction horizontal component force of stayed cable, does not bring into play the tensile property of steel anchor box.The major advantage of steel anchor beam anchoring structure is: operation stage, the drag-line horizontal force was only born by the steel anchor beam basically, and concrete towers wall tensile stress is very little, and is stressed clear and definite; Shortcoming is: each steel anchor beam is separate, and horizontal force is only born by the corresponding one-sided tower wall of single steel anchor beam when disconnected rope occurs, and tower wall concrete will ftracture this moment, and simultaneously, the steel anchor beam adopts the bracket force transfer structure, and the stress concentration phenomenon is serious; Each steel anchor beam is separate, and drag-line anchor point and anchor tube positioning accuracy be difficult control also, and it is loaded down with trivial details to construct, and the space difficulty of construction is large.
