Technical Field
The utility model belongs to the technical field of building structures, and particularly relates to a pretensioned steel strand inflatable membrane structure.
Background
Although the application of the inflatable membrane structure is not as common as the steel structure and the reinforced concrete structure of the modern building, the inflatable membrane structure can be applied to the yurt and the tent of the nomadic nationality. The inflatable membrane structure is mainly characterized in that the membrane surface is pretensioned by inflating the membrane, and the inflatable membrane structure has rigidity, so that a stable structural system is formed. The light and high-strength characteristics of the device can lead the application scene to be wide, and the device can be applied to temporary structures and large-scale space structures.
The common traditional membrane structure is divided into an air bearing type membrane structure, an air rib type membrane structure and an air bag type membrane structure, and the traditional membrane structure is weak in integral rigidity, low in bearing capacity and easy to be influenced by weather factors. Thus, a new structure of an inflatable membrane hybrid structure is presented at present, namely, the inflatable membrane structure is combined with a rigid member to jointly serve as a main body structure to bear external load. As in patent CN104763053, it is proposed to use a collapsible rod for the rigid rod, which can achieve the effect of collapsing and expanding, thereby improving the portability of the rigid rod-inflatable membrane structure. However, the rigidity and stability of its collapsible structure depend to some extent on the connection between the structures, with the problem of uncontrollable rigidity, with a greater risk of runaway.
