Embodiment Construction

[0043] The present invention provides a new type of space structure system. This mooring space structure system uses an inflatable air bag filled with helium as the roof force and enclosure structure, and uses the buoyancy provided by the gas in the inflatable air bag to resist the self-weight of the roof material. According to the analysis, the internal air pressure of the inflatable airbag unit 1 is reasonably controlled, so that the inflatable airbag unit 1 has a certain rigidity, thereby resisting external wind and rain loads. The inflatable airbag unit 1 is composed of an inner membrane and an outer membrane, wherein the inner membrane is a gas barrier layer, and its function is to prevent gas leakage and penetration, and the outer membrane is a supporting layer, and its main function is to bear the internal pressure and pressure of the inflatable airbag unit 1. The internal tensile stress of the wall of the inflated airbag unit 1 generated by the external force.

Abstract

A design method for a mooring space structural system, wherein the mooring space structural system includes an inflatable air bag forming a roof, a support structure for supporting the inflatable air bag, and an anchor structure connected between the bottom of the supporting structure and the ground; The cavity of the inflatable airbag is filled with helium, and the whole is in the shape of a curved surface. Adjacent two inflatable airbag units are connected by an outer membrane; the outside of the inflatable airbag unit is provided with an annular stiffening belt and a sling for hoisting; The connecting beam is supported and connected between the adjacent vertical support tops; the inflatable airbag is connected to the top of the support structure; the anchor structure is a gravity anchor. The present invention has reasonable force and can meet the technical problems of the application of super-large span structures and super-large closed space structures.

Description

technical field [0001] The invention belongs to the technical field of prestressed space structures, and in particular relates to a design method for a moored space structure system. Background technique [0002] Traditional space structure systems usually use rigid materials to resist the self-weight and external loads of the structure. The structure is heavy and consumes steel, which is expensive. Therefore, in some long-span engineering fields, people try to find structural solutions with lower cost and faster construction, and the inflatable membrane structure is one of the solutions. In recent decades, the inflatable membrane structure has been widely used in the construction of large-span, light-weight sports buildings, storage buildings, temporary buildings, etc. This kind of inflatable membrane is to inject a certain pressure of air into the closed space to form a stable structure. It relies on air pressure to generate structural rigidity and resist various external...
