Large-span self-anchored suspension bridge hoisting construction method and temporary tower-girder anchoring device
The invention provides a temporary tower-girder anchoring device. One end surface of a first grid is arranged opposite to one end surface of a second grid, so that acting surfaces of force transfer supports are formed; the two oppositely arranged end surfaces of the first grid and the second grid are supported by the force transfer supports to transfer force, so that horizontal force applied on a side span girder can be transferred to a bridge tower in the process of construction; a jack is mounted in a telescopic sleeve composed of an inner barrel and an outer barrel, one end of the jack is fixedly connected with a steel frame arranged on the end of the outer barrel far from the inner barrel, and an oil tube of the jack enters the outer barrel through an oil tube port arranged on the sidewall of the outer barrel. A large-span self-anchored suspension bridge hoisting construction method adopting the temporary tower-girder anchoring device transfers the horizontal force applied on the side span girder to the bridge tower by means of the temporary tower-girder anchoring device in the process of construction.
