Rotary intersection cable system supporting dome structure

Abstract

The invention discloses a rotary intersection cable system supporting dome structure, and belongs to the field of large-span spatial structures. The rotary intersection cable system supporting dome structure is composed of an upper reticulated shell, lower rotary intersection cable systems and vertical supporting rods. The lower rotary intersection cable systems are of an annular structure defined by a plurality of cable intersected dispersing points. The vertical upper ends of the vertical supporting rods are connected with the upper reticulated shell, and the lower ends of the vertical supporting rods are connected with the lower rotary intersection cable systems. The upper end of each vertical supporting rod is connected with a corresponding reticulated intersection in the upper reticulated shell, and the lower end of each vertical supporting rod is connected with the cable cross portion of the corresponding lower rotary intersection cable system. According to the rotary intersection cable system supporting dome structure, the rotary intersection cable systems and the vertical supporting rods have good space stress performance, the upper reticulated shell is supported, the stress mechanisms of the reticulated shell structure is changed, and horizontal thrust generated by the reticulated shell structure is reduced. The rotary intersection cable system supporting dome structure has the advantages of being novel in structural style, reasonable in structure stress, high in progressive collapse resisting capacity, attractive in building appearance and the like, is convenient to manufacture and mount, and has high practical significance.

Description

technical field [0001] The patent of the present invention relates to the field of large-span dome structures, in particular to a dome structure supported by cable systems arranged in circular crossings. Background technique [0002] With the continuous development of society, people's demand for public event spaces such as large exhibition halls and sports venues is increasing day by day. This phenomenon has also prompted continuous innovation in the form of long-span spatial structures. Not only innovations in terms of safety and economy, but more importantly, innovations in styling to meet people's constantly updated aesthetic needs. In recent years, large-span suspension dome structures, cable dome structures and cable truss structures have been widely used in the construction of sports venues at home and abroad. [0003] Suspension dome structure has reasonable stress, high structural efficiency, clear force transmission path, fully utilizes the mechanical performance...

Problems solved by technology

Once the central ring cable breaks, the structural rigidity will drop significantly, and even lead to the overall collapse of the structure; at the same time, the upper and lower layers are all flexible cables, and the spatial node coordinate positioning is complicated, making construction difficult

[0007] 3. There are also obvious key components in the cable dome structure, that is, the hoop cables. Once the hoop cables fail, it will cause the failure of the oblique stay cables and vertical struts, and even directly cause the continuous collapse of the structure; at the same time, the upper and lower floors The rods are all flexible cables, the spatial node coordinate positioning is complicated, and the construction is difficult
