Support structure, process for producing this support structure, means for practicing the process

Claim 2

Support structure adapted to be erected on a relatively horizontal ground surface, comprising: a stack of layers (15) of loose material, said layers being disposed on top of one another, a flexible envelope (16) at least partially surrounding each said layer (15), each said envelope defining a border (18) situated substantially in a first substantially vertical plane (17), and a support wall (10) disposed on the said ground surface (5, 9) and extending substantially parallel to said first vertical plane (17), said wall having a portion extending vertically upwardly beyond said stack, wherein said wall is disposed at a predetermined distance from said stack so as to define a free space (20) between said vertical plane and said support wall (10).

Claim 3

Structure according to claim 1, said support wall (10) comprises a base (11) bearing on the said ground surface, said stack resting on a part (14) of said base (11).

Claim 4

Structure according to claim 1, wherein said support wall (10) comprises substantially at said portion extending vertically upwardly beyond said stack a table (22) and at least one support plate (24) having two extremities (25, 26) resting respectively on said table (22) and said stack, said support plate (24) being situated above said free space (20).

Claim 5

Structure according to claim 3, wherein said two extremities (25, 26) of said support plate (24) comprise substantially rounded edges.

Claim 6

Structure according to claim 3 further comprising an upper layer (31) covering said stack and said support plate (24), said upper layer extending to said support wall (32, 10).

Claim 7

Structure according to claim 5, and connection means (29) interconnecting said support wall and said stock.

Claim 8

Structure according to claim 6, wherein said connecting means comprises a link (29) having a first extremity fixed to said portion of said support wall (10) extending vertically upwardly beyond said stack, and a second extremity grippingly confined between said stack and said upper layer (31).

Claim 9

Structure according to claim 1, comprising webs (13) disposed in said free space (20) and in a second plane substantially perpendicular to said first plane, said webs (13) being fixed at least to said support wall.

Claim 10

Process for production of a support structure according to claim 1, comprising: preparing a said ground surface (5, 9) substantially horizontal, positioning a said support wall (10) on said ground surface, successively disposing said layers (15) to form a said stack and define a said free space (20) with respect to said support wall (10).

Claim 11

Process according to claim 9, wherein said successive disposition of said layers (15) comprises: positioning a casing plate (43), for the production of a single said layer (15), with respect to the said wall (10), said casing plate having at least one wedge assembly (45), said plate (43) having a surface (44) situated substantially coplanar with said first vertical plane (17) in which are disposed said borders (18) of the said layers when they are produced, unrolling, on each said layer, material forming said envelope (40, 51), and mounting said material along said plate (43), disposing said loose material to a level passing substantially through the upper level of said plate (43), unrolling surplus (46, 146) said material onto an underlying said layer when a desired height of said underlying layer is attained. unwedging said casing plate (43), then subjecting it to a translation along said support wall (10) so as to bring it in a position above said layer (15) under production, so as to effect a subsequent said layer (15).

Claim 12

(amended) Process according to claim 10, wherein said positioning of said support wall comprises: erecting a said support wall (10) comprising webs (13) and a base (11) resting on said ground surface, said webs (13) being fixed to said base and to said wall, and thereafter disengaging said webs from said base when said disposing of said layers is complete.

Claim 13

Process for production of a support structure, comprising: preparing a substantially horizontal foundation (5, 9), positioning a reference plate (12) on said foundation, said reference plate forming with respect to said foundation a right angle, successively disposing layers (15) by stacking with respect to said reference plate (12), wherein each said layer (15) is produced by steps comprising: positioning a casing plate (43) with respect to the said reference plate (12) by means of a wedge assembly (45), said plate (43) having a surface (44) turned toward said layers and situated facing said layers, unrolling, on said foundation or a said layer, a flexible envelope material (40, 51, . . . ) and mounting said material along said plate (43), disposing loose material on said flexible envelope material and coextensive with said surface (44) of plate (43), unrolling surplus (46, 146) said flexible material on an underlying said layer when a desired height of said underlying layer is attained, and undweding said casing plate (43), and subjecting same to a vertical translation along said stack for bringing it into a position above said underlying layer (15), so as to produce a subsequent said layer (15).

Claim 14

Process for production of a support structure, comprising: preparing a substantially horizontal foundation (5, 9), positioning a reference plate (12) on said foundation, said reference plate forming with respect to said foundation a right angle, successively disposing layers (15) by stacking with respect to said reference plate (12), wherein each said layer (15) is produced by steps comprising: positioning a casing plate (43) with respect to the said reference plate (12) by means of a wedge assembly (45), said plate (43) having a surface (44) turned toward said layers and situated facing said layers, unrolling, on said foundation or a said layer, a flexible envelope material (40, 51, . . . ) and mounting said material along said plate (43), disposing loose material on said flexible envelope material and coextensive with said surface (44) of plate (43), unrolling surplus (46, 146) said flexible material on an underlying said layer when a desired height of said underlying layer is attained, and undweding said casing plate (43), and subjecting same to a vertical translation along said stack for bringing it into a position above said underlying layer (15), so as to produce a subsequent said layer (15).
