Construction of houses or similar buildings by means of an inflatable structure

Claim 2

An inflatable support structure for constructing houses or similar buildings comprising an upper membrane and a lower membrane connected hermetically to each other along a peripheral zone thereof wherein the dimensions of the upper membrane are larger than the corresponding dimensions of the lower membrane and the upper and lower membranes form a first pressure chamber constituting an inflatable envelope, a second inflatable pressure chamber fixed to the basis of said first pressure chamber, said pressure chambers being formed of a suitable material for their utilization as support and framing in the construction of houses or similar buildings of concrete or similar or analogous materials, and wherein said first pressure chamber is inflated to a pressure lower than that of said second pressure chamber.

Claim 3

The structure according to claim 1, wherein said pressure chambers are connected to each other by welding.

Claim 4

The structure according to claim 2, wherein said upper membrane is hermetically fixed to said second pressure chamber and said lower membrane is hermetically fixed to said second pressure chamber to form said first pressure chamber.

Claim 5

The structure according to claim 3, wherein said upper membrane is fixed to said second pressure chamber along a first fixing line or zone, said lower membrane is fixed to said second pressure chamber along a second fixing line or zone located at a predetermined distance from said first fixing line or zone, and wherein the dimension of said upper membrane between its fixing lines or zones is larger than the dimension of said lower membrane between its fixing lines or zones.

Claim 6

The structure according to claim 3, wherein said second pressure chamber is fixed to the periphery of said first pressure chamber and defines an open space.

Claim 7

The structure according to claim 5, wherein said first pressure chamber is substantially circular and that said second pressure chamber is formed of a hose having a circular cross-section and arranged as an annulus.

Claim 8

The structure according to claim 5, wherein said first pressure chamber is oblong and said second pressure chamber is an oblong pressure chamber having the same length as said first pressure chamber.

Claim 9

An inflatable support structure for bearing a hardenable substance which forms a shell when cured, wherein the shell defines an enclosed space from which the support structure may be removed, said support structure comprising: an upper membrane having an outside surface upon which the hardenable substance is deposited; a lower membrane having an area less than that of the upper membrane; means for connecting the upper and lower membranes along the peripheries thereof to define a first pressure chamber therebetween which when pressurized causes the upper membrane substantially to define the shape of the shell, and second hermetic chamber means attached to the first pressure chamber adjacent to the peripheries of the upper and lower membranes, said second pressure chamber means being inflatable to a pressure greater than that of the first pressure chamber to stablize the inflated structure on the surface upon which the structure rests.

Claim 10

An inflatable support structure for bearing a hardenable substance which forms a shell when cured, wherein the shell defines an enclosed space from which the support structure may be removed, said support structure comprising: an upper membrane having an outside surface upon which the hardenable substance is deposited; a lower membrane having an area less than that of the upper membrane; means for connecting the upper and lower membranes along the peripheries thereof to define a first pressure chamber therebetween which when pressurized causes the upper membrane substantially to define the shape of the shell, and second hermetic chamber means attached to the first pressure chamber adjacent to the peripheries of the upper and lower membranes, said second pressure chamber means being inflatable to a pressure greater than that of the first pressure chamber to stablize the inflated structure on the surface upon which the structure rests.

Claim 11

The inflatable support structure of claim 8 wherein the means for connecting the upper and lower membranes forms a base of the upper chamber from which the second pressure chamber means is depended.

Claim 12

The inflatable support structure of claim 9 wherein the peripheries of the upper and lower membranes are welded to the base in spaced relation to one another.

Claim 13

The inflatable support structure of claim 9 wherein the second hermetic chamber is arranged to define an open space between portions thereof.
