Stay cable anchoring structure eliminating midspan pulling force of concrete girder
The invention belongs to the bridge construction technical field, and specifically relates to a stay cable anchoring structure eliminating a midspan pulling force of a concrete girder; the stay cable anchoring structure comprises a midspan girder and midspan a first pair of stay ropes supporting the midspan girder; the stay cable anchoring structure also comprises a steel anchor beam vertically connected with the midspan girder in a slide manner; the steel anchor beam is fixedly connected with the midspan girder in an up-down direction vertical to the bridge direction, thus providing upward support force for the midspan girder; the first pair of midspan stay ropes are stressed and tensioned, and the bottoms of the stay ropes are fixed on the steel anchor beam. The stay cable anchoring structure is simple in structure, convenient in mounting, can reconstruct an existing cable-stayed bridge, thus greatly improving bearing structure of the midspan girder, prolonging service life of the bridge floor, reducing maintenance period of the bridge floor cracks, and providing massive promotion value.
