Method for reinforcing hollow slab beam
A method for reinforcing a hollow slab beam comprises the following steps: force conversion devices with round sections are respectively arranged on outer walls of side boards on the two sides of a hollow slab beam bridge; a horizontal prestressed rib is arranged at the plate bottom of the hollow slab beam bridge, the two ends of the horizontal prestressed rib respectively surround the force conversion devices on the two sides of the hollow slab beam bridge and then are fixed on anti-collision guardrails on the two sides of the hollow slab beam bridge; the included angle between a horizontal prestressed rib located between cutting points of the force conversion devices and fixed points of the anti-collision guardrails and the horizontal prestressed rib located at the plate bottom of the hollow slab beam bridge is smaller than 90 degrees, so that the prestress of the horizontal prestressed rib generates horizontal component force; and a steel beam is arranged at the plate bottom of the hollow slab beam bridge. In the method, the horizontal prestressed rib is tentioned for the bridge through the force conversion devices on the two sides of the hollow slab beam bridge, an anchor steel beam adheres to the plate bottom of the bridge, so that hollow slabs interact, the phenomenon that a single plate is stressed is greatly eliminated, the reinforcing efficiency is improved, and the reinforcing effect is better.
