Description

Technical Field

[0001] The present invention relates to the field of air membrane buildings, and in particular to an inflatable emergency storage bin. Background Art

[0002] Architectural membrane materials are composite materials composed of a high-strength fabric substrate and a polymer coating. Inflatable membrane structures utilize flexible architectural membranes as the primary building material, forming a relatively enclosed space with the membranes. Air blowers continuously pump air into the structure, maintaining a relatively stable pressure within the membrane structure and creating a certain pressure differential with the outside world. This ensures the rigidity of the membrane system, thereby resisting external forces and maintaining a stable architectural form.

The prefabricated foundation 2 is annular and comprises a plurality of foundation segments 3 assembled end to end. A strip 4 is fixed to the top of each foundation segment 3. Multiple studs 5 are secured to the top surface of the strip 4 along its length. The bottom perimeter of the membrane 1 is secured to the studs 5 via a clamping assembly 6.

[0031] The foundation section 3 is prefabricated and includes a steel jacket 301 on the outside and filling concrete 302 filled in the steel jacket 301. The cross-section of the foundation section 3 is convex, and its lower half is buried under the ground as a whole.
