Air bag girder type truss for large offshore platform
The invention discloses an air bag girder type truss for a large offshore platform. An air bag girder is used for replacing a web rod layer of an n-truss longitudinal plane truss in the traditional space stereo truss. The air bag girder type truss consists of longitudinal chord rods, transverse chord rods, vertical web rods, transverse oblique web rods, longitudinal oblique web rods and the air bag girder, wherein the air bag girder consists of an elliptical air bag, an air bag upper arc girder, an air bag lower arc girder, air bag hoops, upper arc girder support rods and lower arc girder support rods; after certain air pressure is filled into the elliptical air bag, the whole air bag girder type truss can carry external load and provide buoyancy in water; a large number of air bag girder type trusses and the space stereo truss are mutually connected according to certain rule, so as to form a large offshore platform structure. The air bag girder type truss has the advantages that the weight of the air bag structure is light, the buoyancy property is good, the construction of the space truss is convenient and rapid, and the rigidity is high; a floating type structure system with light weight, high strength, convenient construction, rapid and convenient scale expansion, and partial balance of internal air pressure and external water pressure is formed.
