1. A structure (10) for a guide pillar system of a pneumatic vacuum elevator (280), wherein the structure (10) comprises:
a central hollow pillar section (20) positioned in an external cylinder (135) of the pneumatic vacuum elevator (280), wherein the central hollow pillar section (20) comprises:
at least four sides comprising a first side (30), a second side (40), a third side (50), and a fourth side (60); and
at least three grooved rib profiles (70) adapted to mechanically couple the central hollow pillar section (20) to one or more elevator components using a screwing mechanism,
wherein each of the at least three grooved rib profiles (70) are attached to an inner surface of the first side (30), the second side (40), and the third side (50);
at least two curved sections (80) positioned at a first predefined portion of an outer surface of the first side (30) and the third side (50), wherein each of the at least two curved sections (80) are adapted to provide structural integrity and one or more radius edges to the fourth side (60) of the central hollow pillar section (20);
at least two single lip channeled sections (100) positioned at a second predefined portion of the outer surface of the first side (30) and the third side (50), wherein each of the at least two single lip channeled sections (100) comprises a first wall (110) and a second wall (120), wherein each of the at least two single lip channeled sections (100) are adapted to:
receive and support a covering sheet (190) of the external cylinder (135) of the pneumatic vacuum elevator (280) at the first wall (110); and
receive and support a rubber beading (180) at the second wall (120).
