Foldable and unfoldable connecting rod-inflatable membrane structure
The invention discloses a foldable and unfoldable connecting rod-inflatable membrane structure. The structure is characterized by being composed of three parts, namely an inflatable membrane, a connecting rod mechanism and a cable sleeve; the cable sleeve comprises two end portion lantern rings and at least one middle lantern ring arranged between the two end portion lantern rings at an interval; the end portion lantern rings and the middle lantern ring are fixedly connected with the inner surface of the inflatable membrane, respectively; the connecting rod mechanism is composed of n four-connecting rod mechanisms connected with each other by use of n-1 pivoting joints; each four-connecting rod mechanism is composed of a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, all of which are mutually and rotatably connected together; the connecting rods are the same in length; the joint of the first connecting rod and the second connecting rod in the first four-connecting rod mechanism and the joint of the third connecting rod and the fourth connecting rod in the last four-connecting rod mechanism are mechanically connected with the two end portion lantern rings, respectively, while the other n-1 pivoting joints are mechanically connected with the middle lantern rings. The connecting rod-inflatable membrane structure has the advantages of a traditional inflatable beam structure, and the rigidity, the stability and the bearing capability of the structure are greatly improved; the structure can be folded and reused a plurality of times, is good in economic benefit, and has huge potential in temporary building application.
