Abstract

The invention relates to the technical field of building structures, in particular to a cable dome structure. The cable dome structure comprises a central pressing rod, an inner ring supporting component and an outer pressing ring beam, and the central pressing rod, the inner ring supporting component and the outer pressing ring beam are coaxially arranged from inside to outside in sequence. The inner ring supporting component comprises a ring cable assembly and supporting rod assemblies. The supporting rod assemblies are formed along the ring cable assembly in a continuous connecting mode. Each supporting rod assembly comprises two side supporting rods and a middle supporting rod, wherein every two of the two side supporting rods and the middle supporting rod form a plane, the upper endsof the three supporting rods are connected to form an upper fulcrum of the supporting rod assembly, the lower ends of the two side supporting rods serve as two side fulcrums of the supporting rod assembly, the lower end of the middle supporting rod serves as a lower fulcrum of the supporting rod assembly, the side fulcrums and the lower fulcrum are connected with the ring cable assembly, the upperfulcrum is connected with the lower end of the central pressing rod through an inner ring upper oblique cable and connected with the upper end of the central pressing rod through an inner ring ridgecable, the lower fulcrum is connected with the upper end of the central pressing rod through an inner ring lower oblique cable, and the upper fulcrum and the side fulcrums are connected with the outerpressing ring beam.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a cable dome structure. Background technique [0002] The cable dome structure originated from the idea of ​​a tensegrity structure, and on this basis, a topology form of a tensegrity structure was proposed, and a prestressed space composed of continuous tension cables and discontinuous compression struts was constructed. Structural system - cable dome structure. The cable dome structure has the advantages of novel shape, ingenious conception, light weight, fast construction, and economical cost. It has strong vitality and broad application prospects. [0003] At present, the cable dome structures in practical engineering can be roughly divided into two types: Geiger type (ribbed ring type) cable dome and Levy type (joint square type) cable dome. Ribbed ring cable domes have a relatively simple structure, relatively easy construction, and are less sensitive to const...
