In general, the structure of an air tent is a combination of a plurality of struts made of a flexible airtight cylinder and a plurality of beams to form a framework, and when used, pressurizes compressed air into the cylinder to inflate it, A column and a beam are formed, and a sheet material is covered on the outside to form a tent. (For example, see Patent Document 1)
In addition, there are some which define an indoor space in cooperation with a large number of air tubes forming a framework of the side surface and the upper surface of the room and a film body stretched between the air tubes. (For example, see Patent Document 2)

FIG. 10 is a perspective view of a polygonal air house described in Patent Document 1 below, where 1 is a vertical air column having a dogleg-shaped bent portion in the middle, 2 is a horizontal column member (horizontal air column), and 4 is An air concentration bag is a rough structure of an air tent, and air is injected from seven charge (exhaust) air valves.
By arranging the air concentration bag 4 at the top, it can be distributed to each other vertical air column and can be inflated uniformly, troubles such as breakage of tent cloth and inner cloth due to irregular bending of the air column, or Auxiliary work for correcting the bending can be eliminated. Further, as compared with a conventional hemispherical dome-shaped air house, the weight can be reduced and the size can be reduced, the number of processing steps can be reduced, and the frequency of repair can be greatly reduced.

11 and 12 are film structures described in Patent Document 2 below, FIG. 11 is a plan view of the film structure, and FIG. 12 is a cross-sectional side view of the film structure.
The membrane structure 1 is composed of a large number of air tubes 3 forming a framework and a membrane body 5 stretched between the air tubes 3, and a semicircular indoor space 7 is formed inside the membrane structure 1. A decoration 9 is attached to the upper part of the membrane structure 1.
