Abstract
The utility model relates to an external prestressed reinforcement structure of an ordinary steel-bar reinforced concrete hollow plate girder. The utility model is achieved in that a baffle plate and a lining plate are symmetrically welded on main reinforcements which are arranged on two ends of a bottom board of the hollow plate girder, the lining plate arranged on the inside of the baffle plate is connected with the baffle plate with the outside of the baffle plate which is connected with a anchorage of which two ends are connected through a prestressed steel strand passing through the baffle plate, and the reinforced concrete is poured around the baffle plate, the lining plate, and the anchorage. The utility model has the beneficial effects that the intensity and stiffness of the hollow plate girder are enhanced, the fracture indexes are improved, and the bridge bearing capacity is increased.
Description
Technical field
The utility model relates to a kind of reinforcing technique of plain bars concrete hollow board beam, specifically, relates to a kind of external prestressing strengthening structure of plain bars concrete hollow board beam.
Background technology
For the plain bars concrete hollow board beam in the present bridge construction, there is the hypodynamic phenomenon of carrying, make the strength and stiffness of bridge beam body not reach designing requirement.
Summary of the invention
The purpose of this utility model provides a kind of bearing capacity that can improve plain bars concrete hollow board beam, can improve the external prestressing strengthening structure of the plain bars concrete hollow board beam of plain bars concrete hollow board beam strength and rigidity.
The utility model is achieved in that a kind of external prestressing strengthening structure of plain bars concrete hollow board beam, is symmetrically welded with baffle plate and liner plate on the master's muscle of hollow slab beam base plate two ends; Liner plate is connected at the inboard of baffle plate and with baffle plate, is connected with ground tackle in the outside of baffle plate, passes baffle plate by prestress wire between the ground tackle of two ends and connects, and is cast with concrete around baffle plate, liner plate and ground tackle.
Liner plate at the bridge main beam two ends is two and plural right-angled triangle steel plate, and wherein, a right-angle side is connected with plate washer, and another right-angle side is connected with the base plate master muscle of bridge main beam.
The beneficial effects of the utility model are: improved the strength and stiffness of hollow slab beam, improved the crack index, improved the bearing capacity 30%-40% of bridge.
