Disc-shaped performance stage capable of changing into spherical surface from plane

Abstract

The invention discloses a disc-shaped performance stage capable of changing into spherical surface from plane, comprising a central stage (32) and a plurality of stage unit structures (31) arranged around the central stage, wherein each stage unit structure comprises a group of sector units (31a, 31b and 31c) and a lifting device; the sector units are arranged along a straight line, and adjacent sector units are mutually connected; the lifting device is arranged on the lower part of the sector unit to support the sector unit and cause the sector unit to rise and lower; the lifting device is abridging device (34a, 34b and 34c); the lower part of the bridging device is supported on the ground, and the upper part is connected with the end of the sector unit. The performance stage of the invention can be quickly spliced into a large round stage before performing, can change the stage between the spherical surface state and the plane state in the performing process so as to satisfy the requirements of stage performances and can be quickly installed, positioned, removed and transported after performances end.

Description

technical field [0001] The invention relates to a stage structure, in particular to a large disk-shaped performance stage structure capable of transforming from a plane to a spherical surface. Background technique [0002] In large-scale sports games or large-scale performances, in order to meet the needs of programs and performance creativity, large-scale stages are often required. This kind of stage requires quick assembly before the performance, and can present different shapes during the performance. For example, the entire stage convex It rises to form the shape of the earth's surface or is concave to form a bowl shape, on which actors can perform performances, which will give the audience a strong shock during the performance; Quickly disassemble in a short period of time so that the venue can be vacated for athletes to compete, which requires the stage to meet the technical requirements and also meet the creative requirements of the stage. At present, no such stage ha...

[0002] In large-scale sports games or large-scale performances, in order to meet the needs of programs and performance creativity, large-scale stages are often required. This kind of stage requires quick assembly before the performance, and can present different shapes during the performance. For example, the entire stage convex It rises to form the shape of the earth's surface or is concave to form a bowl shape, on which actors can perform performances, which will give the audience a strong shock during the performance; Quickly disassemble in a short period of time so as to free up the venue for athletes to compete, which requires the stage to meet the technical requirements as well as the creative requirements of the stage. At present, no such stage has been developed.
