Title:
HYDRAULIC SELF-ELEVATING INTEGRATED CABLE-STAYED BRIDGE LIFTING FORMWORK
Document Type and Number:
WIPO Patent Application WO/2022/048320
Kind Code:
A1
Abstract:
A hydraulic self-elevating integrated cable-stayed bridge lifting formwork, comprising a self-climbing system, a crane system and a hydraulic lifting system. The self-climbing system comprises an anchoring seat pre-buried on the surface of a structure, a track attached to the anchoring seat, and a climbing assembly reversely hooked on the track; the climbing assembly is provided with a reverse hook part in clearance fit with the track; the climbing assembly and the track are fixed by means of pin joint; the crane system is connected to the climbing assembly; the crane system climbs and moves along the track by means of the climbing assembly; the hydraulic lifting system is provided on the crane system and moves longitudinally or transversely relative to the crane system so as to be used for lifting a structure to be spliced to the top of the installed structure to install the structure. By providing the hydraulic self-elevating integrated cable-stayed bridge lifting formwork attached to the side wall of the surface of the structure, after construction of a single-section structure is completed, the single-section structure is lifted to the next-section lifting position by means of a crane system of the formwork, and this operation is repeated in order; the technological operation is easy, the construction time is saved, and the construction efficiency is improved.
