Method for mounting and positioning steel anchor beams for constructing cable-stayed bridge main tower
The invention relates to a method for mounting and positioning steel anchor beams for constructing a cable-stayed bridge main tower. The steel anchor beams are mounted and positioned by using a detachable and reusable steel anchor beam support rack system. The detachable and reusable steel anchor beam support rack comprises a rigid support rack I and chain hoists II, wherein the rigid support rack I is arranged on a mounted No. n steel anchor beam and is used for jacking a No. n+1 steel anchor beam; after a No. n+2 steel anchor beam is mounted, four chain hoists II are mounted on the No. n+2 steel anchor beam; the No. n+1 steel anchor beam is hoisted; the rigid support rack I of the steel anchor beams is demounted; then the chain hoists II are used for putting the No. n+1 steel anchor beam in place. According to the detachable and reusable support rack system comprising the rigid support rack and the chain hoists, the steel anchor beams are mounted and positioned; the problem that the construction operation surface is insufficient is solved; the construction period is shortened; the cost is reduced; the device is simple and convenient to operate and convenient to control.
