Abstract

The invention belongs to the technical field of building structures, and relates to a hoop cable node used for an irregular plane cable net. The cable connecting body is connected with the vertical bar connecting lug plate; the top and bottom of the pin connecting body are respectively provided with an upper pin end plate and a lower pin end plate, and the oblique cable lug plate is fixedly installed on the outer surface of the pin connecting body. The end plate of the pin shaft and the end plate of the lower pin shaft are connected with the ring cable connecting body through high-strength bolts. The ring cable connecting body is composed of a ring cable connecting plate and a cover plate connected by high-strength bolts. The cable passes through the cable hole and is connected to the ring cable connector; the vertical rod connecting ear plate is welded on the cover plate, and the external vertical support rod is connected to the node through the vertical rod connecting ear plate. By arbitrarily changing the angle between the radial cable and the ring cable, standardized manufacturing can be realized, and the manufacturing cost is low.

Description

Technical field: [0001] The invention belongs to the technical field of building structures, and relates to a hoop cable node of a prestressed steel structure of a cable rod, in particular to a hoop cable node for an irregular plane cable net. Background technique: [0002] The cable-strut prestressed structure is a kind of spatial structural system that is composed of cables and rods as the basic units, and the structural rigidity is provided by prestressing. The cable-strut prestressed structure can be traced back to the tensioned overall structure proposed by the famous American architect R.B.Fuller in the 1940s. Following Fuller, many scholars and engineers have analyzed and interpreted this type of structural system from different angles. In the 1980s, B.H.Geiger and M.Levy in the United States further evolved and developed Fuller's ideas, and proposed a cable dome structure and applied it to practical engineering. After the emergence of flexible prestressed structure...
