The invention discloses an inflatable spreading support framework for a multi-layer sandwich air inflation cabin. Middle air inflation pipes are connected between two adjacent annular air inflation pipes, arc-shaped air inflation pipes are connected between each outer-end annular air inflation pipe and the corresponding annular air inflation pipe, and accordingly, the inflatable spreading support framework is formed; the annular air inflation pipes and the middle air inflation pipes are communicated, the outer-end annular air inflation pipes and the arc-shaped air inflation pipes are communicated, and the arc-shaped air inflation pipes and the annular air inflation pipes are communicated. Before launch, the spreading support framework can be flexibly folded with the air inflation cabin; after the framework is launched and enters an orbit, the inflatable spreading support framework takes air inflation pressure as driving force and can be axially and radially spread respectively, so that assistance is provided for spreading of the air inflation cabin, and smooth completion of on-orbit inflatable spreading of the air inflation cabin is guaranteed; after inflatable spreading, the inflatable spreading support framework is solidified and formed, so that the framework can still keep a structure shape under the gas leakage condition, the support framework structure meeting the structure rigidity requirements is formed, and each layer of connected bags are constrained and supported to a certain extent.
