## Abstract

The invention provides a support structure (10) comprising at least one cylindrical pillar (16) of vertical main axis, having a bottom end (16i) that is connected to the ground (14) and a top end (16s) connected to a component to be supported; the support structure being characterized in that the pillar (16) includes at least one helical slot (20) coaxial about the main axis of the pillar (16).

## Claims

### Claim 1

A support structure (10) comprising at least one cylindrical pillar (16) of vertical main axis, having a bottom end (16i) that is connected to the ground (14) and a top end (16s) connected to a component to be supported,
wherein the pillar (16) includes at least one helical slot (20) coaxial about the main axis of the pillar (16), and
wherein the pitch (22) of said at least one helical slot (20) varies over the entire axial length of the slot (20).

### Claim 2 (depends on 1)

A support structure (10) according to claim 1, wherein the width (24) of said at least one helical slot (20) is constant over the entire axial length of the slot (20).

### Claim 3 (depends on 1)

A support structure (10) according to claim 1, wherein the width (24) of said at least one helical slot (20) varies over the entire axial length of the slot (20).

### Claim 4 (depends on 1)

A support structure (10) according to claim 1, wherein the pillar (16) includes a plurality of helical slots (20) that are axially offset.

### Claim 5 (depends on 1)

A support structure (10) according to claim 1, wherein at least one end of said at least one helical slot (20) opens out into a rounded hole.

### Claim 6 (depends on 1)

A support structure (10) according to claim 1, wherein at least one end of said at least one helical slot (20) opens out at a top (16s) or bottom end (16i) of the pillar (16).

### Claim 7 (depends on 1)

A support structure (10) according to claim 1, wherein it comprises a plurality of pillars (16) that are parallel.
