Abstract

The invention provides a multi-directional node connection device for a CFRP cable suspen-dome structure. The multi-directional node connection device comprises a fixed end main body, a radial anchoring component, a vertical supported rod connection component and a diagonal support connecting component; the vertical supported rod connection component is fixedly mounted on the upper face of the fixed end main body and used for connecting rod parts in the vertical direction; an arc groove is formed in the bottom of the fixed end main body, a cover plate is arranged on the body of the fixed end main body, and the arc groove and the cover plate are used for fixing a circumferential CFRP cable; the radial anchoring component and the diagonal supported connection component are arranged between the vertical supported rod connection component and the fixed end main body and used for connecting rod parts in the radial and diagonal directions. The multi-directional node connection device effectively connects a CFRP radial cable, the CFRP circumferential cable and the multi-directional rod parts such as the vertical supported rod parts and the diagonal supported rod parts together to work, and also overcomes the defects of poor shear resistance and large prestressing loss of CFRP cables.

Description

technical field [0001] The invention relates to the field of civil engineering or the technical field of steel structure nodes, in particular to a multidirectional node connection device for a CFRP cable suspension dome structure. Background technique [0002] Suspension dome is a form of prestressed long-span steel structure, which is widely used in practical engineering due to its advantages of high structural efficiency and easy self-balancing load. The cable is the key component of the suspension dome structure, but as the suspension dome structure has higher and higher requirements on the span and life cycle design, the traditional steel cable is gradually difficult to adapt to this development requirement. [0003] CFRP (Carbon Fiber Reinforced Polymer, carbon fiber reinforced composite material) cables have the advantages of light weight, high strength, and good corrosion resistance. Using CFRP cables instead of steel cables to form a new CFRP cable-supported dome str...
