Document Type and Number:
WIPO Patent Application WO/2022/242103
Kind Code:
A1
Abstract:
A descending type double-span movable scaffolding system and a construction method. The scaffolding system comprises main beams (1), main nose beams (2), corbels (3), propelling flatcars (4), cross beams (5), an outer formwork (6), a front hanging beam (7), and a rear hanging beam (8), the number of the main beams (1) is two, the main beams (1) are connected by means of a plurality of pairs of cross beams (5), every two cross beams (5) form a group, and the bottom ends of the cross beams are connected by means of bolts; the main nose beams (2) are fixedly connected to the two ends of each main beam (1), the three pairs of corbels (3) are respectively located at the bottom of each main beam (1) and the bottoms of the main nose beams (2) at the two ends of each main beam (1) and used for supporting the main beams (1) and the main nose beams (2), each pair of corbels (3) are connected by means of a connecting plate, and each propelling flatcar (4) is slidably connected to the tops of the corbels (3). According to the scaffolding system, through the arrangement of an attached connecting device (9), after a hydraulic device on each propelling flatcar (4) enables two parts of the outer formwork (6) to be closed, the two beams (5) in the same pair can be fixed at the same time, the top of the attached connecting device (9) is embedded into the connecting position of the outer formwork (6), and a gap at the connecting position cannot be vertically through, such that the situation of continuous leakage is prevented, and the safety is improved.
