Pneumatic wall structure and a method of making and erecting same

A pneumatic wall structure comprising:

• an inner flexible tent sheet;
• a central flexible tent sheet;
• and
• an outer flexible tent sheet;
• wherein the inner, the central and the outer flexible tent sheets are arranged to form a two-layer wall structure comprising (i) an inner layer formed by the inner tent sheet and the central tent sheet and (ii) an outer layer formed by the central tent sheet and the outer tent sheet;
• and
• wherein the inner layer is inflatable and provides a main support structure for the wall structure, and the outer layer forms a convection space which is in communication with apertures in said outer sheet, and through which ambient air is capable of flowing;
• wherein inflatable support tubes are arranged between the central tent sheet and the outer tent sheet to provide redundancy to the main support structure and to provide a spacer between the central tent sheet and the outer tent sheet.

A method of making a pneumatic wall structure comprising:

• providing an inner, a central and an outer flexible tent sheet;
• arranging the inner, the central and the outer flexible tent sheets to form a two-layer wall structure comprising (i) an inner layer formed by the inner tent sheet and the central tent sheet and (ii) an outer layer formed by the central tent sheet and the outer tent sheet, wherein the inner layer is inflatable to provide a main support structure for the pneumatic wall structure and the outer layer forms a convection space is in communication with apertures in said outer sheet, and through which an ambient air is capable of flowing;
• and
• arranging inflatable support tubes between the central tent sheet and the outer tent sheet to provide redundancy to the main support structure and spacers between the central tent sheet and the outer tent sheet.

A method of erecting a pneumatic wall structure, the pneumatic wall structure comprising an inner, a central and an outer flexible tent sheet, the flexible tent sheets being arranged to form a two-layer wall structure comprising (i) an inner layer formed by the inner tent sheet and the central tent sheet and (ii) an outer layer formed by the central tent sheet and the outer tent sheet, the method comprising:

• inflating the inner layer to provide a main support structure for the pneumatic wall structure and the outer layer forms a convection space into which an ambient air is capable of flowing;
• inflating the support tubes to provide redundancy to the main support structure;
• and
• allowing ambient air to flow into the outer layer which forms a convection space coupled in communication with ambient atmosphere via apertures in said outer tent sheet.

A pneumatic enclosure having a wall structure comprising:

• an inflatable inner layer delimited by first and second flexible sheets;
• and
• an outer layer delimited by said second flexible sheet and a third flexible sheet;
• said outer flexible sheet having apertures therethrough which connect said outer layer with ambient atmosphere external to said enclosure, whereby, in a deployed state of said pneumatic structure, said outer layer between said second and third flexible sheets is maintained at ambient air pressure, and ambient air is permitted to circulate through said outer layer between said second and third flexible sheets;
• and
• said inflatable inner layer being inflated in said deployed state of said pneumatic structure.
