Non-self-balanced beam string structure for reinforcing large-span continuous beam bridge
The invention discloses a non-self-balanced beam string structure for reinforcing a large-span continuous beam bridge, relates to the technical field of bridge reinforcement of bridge structure engineering of the civil engineering specialty, and aims to combine and improve a conventional beam string structure technique and a bridge reinforcing technique of a large-span spatial structure of the house construction engineering. The non-self-balanced beam string structure mainly consists of a truss, vertical support rods and a prestressed cable. The non-self-balanced beam string structure has the non-self-balance characteristic that the prestressed cable is not connected with self-anchorages at two ends of the truss at the upper part, but is fixed on bridge piers on two sides of a bridge span through drawing cable anchoring devices, and moreover vertical counter force generated through prestress tension of the prestressed cable acts on a main bridge beam through the truss, so that the effects of reinforcing the bridge beam and improving the bearing property of the bridge beam are achieved.
