Stiffness-supported dome structure

Abstract

The invention relates to a stiffness-supported dome structure, which is a cable dome with a flexile upper part and a rigid lower part and has two parts, wherein the upper layer is a spatial cable net structure and comprises a radial inhaul cable (6) and a slant inhaul cable (5); the lower layer is a support structure system formed by a toroidal tie bar (4), a vertical stay bar (2) and a slant tie bar (3); the peripheries of the two parts are connected with an outmost ring compression rigid ring beam (1) to form a stress loop; each bar component on the upper layer structure is a flexible inhaul cable, and each bar component on the lower layer support structure system is a rigid tie bar; and the upper end of the vertical stay bar (2) is connected with nodes of the upper layer cable net structure, and the lower end thereof is connected with nodes of the toroidal tie bar (4) and the slant tie bar (3) of the lower layer support structure system. The stiffness-supported dome structure in the invention has strong bearing capability, high stability, large span, simple and rapid stretching process, unified bar component specification, concise nodes and wide application range, and greatly lowers the construction difficulty.

AI Technical Summary

Benefits of technology

This patented device uses cables that are stretchable on top of an elastic supporting body called a domicile. These cords help distribute load more evenly over different parts of the system. They also have special features like soft plates covering their surface, allowing water vapor pass through while still providing strong protection against damage from external factors like weather conditions. Overall this design allows for efficient use of space without sacrificing its effectiveness due to lack of gridiness.

Problems solved by technology

This patents discusses different types of architectures used in building constructions such as prestressed refrigerated enclosable shelf (PRES), suspended domes, cables that use struts made of lightweight metals like aluminum instead of traditional metal bars). These technical problem addressed in them include requiring high supporting capacity due to their size, weightiness, flexibility, stability during installation, difficulty in maintain balance when pulling out wires, complexity in constructing the cable damper joint, and potential issues related to seismicity caused by earthquakes.
