Method for mounting spherical rib-ring-shaped rope vault structure by geometric method

Abstract

The invention discloses a method for mounting a spherical rib-ring-shaped rope vault structure by a geometric method. The method comprises the following steps: firstly, connecting and suspending a dorsal rope to a pressed ring beam; secondly, connecting the dorsal rope and one end of a central vertical pressure lever of which the lower part is provided with a temporary mounting scaffold, jacking the central vertical pressure lever to a designed elevation of which the elevation point is the vertex elevation of the rope vault; thirdly, connecting one end of a central oblique rope to the dorsal rope, and connecting the other end of the central oblique rope to the other end of the central vertical pressure lever; fourthly, connecting one end of the vertical pressure lever and the dorsal rope, connecting a ring rope and the other end of the vertical pressure lever and connecting one end of the oblique rope and the dorsal rope ring by ring from inside to outside, connecting the other end of the oblique rope, the other end of the vertical pressure lever and the ring rope, and jacking the vertical pressure lever; and finally, tensioning an edge oblique rope, and anchoring the edge oblique rope to the pressed ring beam. The construction method for the rope vault structure only needs to tension the oblique ropes, and can perform mounting according to the numerical values in a table given by the invention so that the structure of the primary extremely-high construction technology can be popularized universally.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for installing a spherical rib ring type cable dome structure using a geometric method. Background technique [0002] The Cable Dome structure is a new type of pre-tensioned long-span structure realized after the American engineer Geiger developed and promoted Fuller’s tensioned overall thought. It embodies Fuller’s idea that "the island of pressure exists in the ocean of tension". It is a full tension system with extremely high structural efficiency. Among them, the Costa del Sol Dome in St. Petersburg, Russia (210m in diameter), the Olympic Stadium in Seoul, South Korea (119.8m in diameter), and the Georgia Dome (elliptical area: 240.79m×193.02m), the main stadium of the Atlanta Olympic Games in the United States, are the most eye-catching. However, the existing construction methods require relatively high calculation techniques and are difficult for ordinary technicians t...
