Description
Technical Field
The application relates to the technical field of guy cables, in particular to a synchronous lifting control guy cable system.
Background
39 to 42 layers of 14 projects in the fourth period of a building, which are built by the company, are air galleries, the span of the gallery of the steel concrete arch structure is 45.6m, the two layers are totally two, the layer height is 4.5m, and the installation elevation is 127.85m. The corridor concrete main structure adopts an arc-shaped steel concrete arch structure with a pull rod, the corridor width (the south-north dimension) is 32.25m in total, three arc arches are arranged in total, arch legs are supported on frame-type steel concrete columns of two towers, and the columns adopt rectangular steel pipe concrete columns. The compression bar is a square steel tube concrete member. The arch pull rod has larger tension, a hollow rectangular steel pipe is adopted, and the steel pipe extends into the tower for one span; the hanging columns and the floor primary and secondary beams are steel columns and steel beams; the floor slab is a profiled steel sheet-reinforced concrete composite floor slab, and structural columns of the supporting arch bodies of the two towers are rectangular steel tube concrete columns.
Because the whole dead weight of this vestibule steel concrete arch structure reaches 1310 tons, and the mounting height exceeds 100m, through many schemes comparison, adopt whole synchronous lifting hoisting technique to install. Because promote highly big, there is the wind-tunnel effect at the tower top, and wind-force is great, promotes the in-process at the steel vestibule, because the reason of wind load and dynamic load, probably makes vestibule hoisting unit produce too big swing to influence the security that the vestibule promoted. In order to avoid the overlarge swing during the lifting process, a guy rope is needed to be arranged for control. However, the lifting height reaches 127m, the rope wind rope needs to form a certain included angle with a lifting object on the horizontal plane to play a role, so that a large field and a large space are needed, the field is narrow, and the condition of arranging a conventional cable wind rope is not met.
