Abstract

The invention discloses a connecting structure used for a suspend-dome structure. The suspend-dome structure is a structure formed by connecting an upper chord single-layer spherical reticulated shell, an oblique cable and hoop cables through a vertical compression rod. In the connecting structure, the oblique cable, the hoop cables and the vertical compression rod are connected with each other through a welded hollow spherical joint. The welded hollow spherical joint forms three holes in the horizontal hoop cable direction, wherein two holes allow one hoop cable to penetrate the welded hollow spherical joint and be anchored through a cast anchor, the other hole allows a washer inside the welded hollow spherical joint to be anchored with a screw cap to form a connecting cable head, and the connecting cable head is connected with a threaded sleeve through the other hoop cable; the welded hollow spherical joint forms the other hole in the oblique cable direction, the washer used inside the welded hollow spherical joint is anchored with the screw cap to form the other connecting cable head, and the connecting cable head is connected with the hoop cables through the threaded sleeve. After the connecting structure is adopted, the construction of the suspend-dome structure is very convenient, the cable force can be adjusted times and again, and the disadvantage that the cable force in the prior suspend-dome structure engineering is difficult to be consistent with the theoretical value can be overcome.

Description

technical field

[0001] The invention relates to the field of architecture, in particular to a connection structure for a suspend dome structure. Background technique

[0002] Suspension dome structure is a new structural form proposed by Japanese scholar M Kawaguchi in 1993. It combines the advantages of single-layer reticulated shell and cable dome structure, and has good mechanical properties. The suspensive dome structure is a self-balancing structural system based on improving the stability of the single-layer spherical reticulated shell and reducing the dependence on external components. On the one hand, it improves the stability of the single-layer reticulated shell structure and enables the structure to span larger space; on the other hand, the new structural system is a self-balancing system, which does not need to be shaped by external components, reducing the dependence on external components.

[0003] But it also has the following problems:
