Diamond shaped cable dome structure

Abstract

The invention discloses a diamond-type cable dome structure which comprises an inner ring cable, an outer ring cable, a middle ring cross cable, an outer ring beam, inner ring support rods, outer ring support rods and middle ring support rods. An anchor point of the outer ring cable is arranged between every two outer ring support rods; a cross node of the middle ring cross cable is arranged between every two middle ring support rods; the positions of the inner ring support rods and the middle ring support rods correspond to those of the anchor points, and the positions of the cross nodes correspond to those of the outer ring support rods; outer dorsal cables are arranged between the top ends of the outer ring support rods and the cross nodes, and outer valley cables are arranged between the anchor points and the cross nodes; inner valley cables are arranged between the top ends of the inner ring support rods and the cross nodes, outer radial cables are arranged between the two ends of the middle ring support rods and the anchor points, and inner radial cables are arranged between the top ends of the middle ring support rods and the top ends of the inner ring support rods and between the bottom ends of the middle ring support rods and the bottom ends of the inner ring support rods. The diamond-type cable dome structure is reasonable in structure, exact in force transmission, easy and convenient to construct, stable in structure and high in bearing capacity and is an efficient large-span building structure form.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a diamond-shaped cable dome structure. Background technique [0002] The development of long-span buildings and corresponding large-span space structures is one of the important symbols representing a country's architectural science level. Due to people's demand for long-span space, high-strength steel cables are increasingly used in building structures. my country's suspension cable structure began to develop in the middle of the last century, and engineering practice has gradually increased. However, compared with other spatial forms such as grids and reticulated shells, the development of cable suspension structures is still relatively slow. [0003] The suspension cable structure resists the external load through the axial tension of the cable, which can make full use of the strength of the steel. When high-strength materials are used, the self-weight of the structure can ...
