To obtain an air beam house which is hard to move by wind or the like and easily erected and removed, by housing a based end of each gate-like beam in a long box foundation which serves as a housing box for carrying, as well, when filled with air to erect a skeleton beam.

Gate-like beam portions 21 which are separately arranged in parallel with each other when filled with air, and a cross beam portion 22 which connects the gate-like beam portions 21 to each other when filled with air, constitute a skeleton beam 20. Further, a cover sheet which closes almost the entire body of the skeleton beam 20 is provided. When filled with an to erect the skeleton beam 20, a base end of each gate-like beam portion 21 is housed in or locked to a long box foundation 30. The long box foundations 30 can be combined with each other in one body by a connector, to thereby serve as a housing box for storing and carrying the skeleton beam 20. Thus, an air beam house which is hard to move by wind or the like, and easily erected and removed can be obtained.
