Cable net structure for super-large-span pneumatic membrane structure and arrangement method

Abstract

The invention discloses a cable net structure for a super-large-span pneumatic membrane structure and an arrangement method. According to a cable net system for the super-large-span pneumatic membranestructure, through the reasonable arrangement and combined action of a stay single cable, a stay double cable and a longitudinal reinforcing cable, a cable membrane of the super-large-span pneumaticmembrane structure is uniform in stress, the deformation of the cable membrane is further reduced, and the safety and stability of the pneumatic membrane structure with the span of 150 m or above under the extreme weather condition can be guaranteed.

Description

technical field [0001] The invention belongs to the field of membrane structures, and in particular relates to a cable net structure and a laying method for super-large-span inflatable membrane structures. Background technique [0002] The inflatable membrane structure has been widely used in the construction of closed storage yards such as electric power, coal, steel, cement, and ports in recent years because of its good airtightness, low cost, energy saving and environmental protection. Due to the limitation of equipment layout and operating conditions, the span of this kind of closed storage yard can reach more than 150m ~ 200m. [0003] In actual engineering, most large-span inflatable membrane structures use a single cable-stayed cable network system. Under the loads of wind and snow, as the span of the inflatable membrane structure further increases, the stress and deformation of the cable-membrane continue to increase, resulting in the inability to meet Equipment ope...

Problems solved by technology

[0003] In actual engineering, most large-span inflatable membrane structures use a single cable-stayed cable network system. Under the loads of wind and snow, as the span of the inflatable membrane structure further increases, the stress and deformation of the cable-membrane continue to increase, resulting in the inability to meet Equipment operation and structural safety requirements, the current single cable-stayed cable network system inflatable membrane structure span is controlled below 150m
