Structure for constructing an improved guide pillar system of a pneumatic vacuum elevator

A pneumatic vacuum elevator (300) comprising:

• an external cylinder (30) comprising an elevator cabin (210) inserted therein, wherein the external cylinder (30) comprises a plurality of cylinders coupled using a base ring (310) and a band ring (320);
• a column (20) positioned in the external cylinder (30), wherein the column (20) comprises at least four sides comprising a first side (40), a second side (50), a third side (60), and a fourth side (70);
• at least one angled section (80) positioned at a first predefined portion of each of the first side (40) and the second side (50), wherein the at least one angled section (80) is adapted to provide one or more radius edges to the third side (60) of the column (20);
• at least one channel section (90) positioned at a second predefined portion of each of the first side (40) and the second side (50), wherein each of the at least one channel section (90) comprises:
• a first wall (100) adapted to support a covering sheet (110) of the external cylinder (30) of the pneumatic vacuum elevator, wherein the first wall (100) comprises a first projection (120) comprising a gasket lining (130) adapted to provide a vacuum tight sealing between the covering sheet (110) and the first wall (100);
• a second wall (140) adapted to support a beading (150) adapted to force the covering sheet (110) against the first wall (100) to prevent one or more relative movements of the covering sheet (110) with respect to the first wall (100),
• wherein the second wall (140) comprises a second projection (170) adapted to interlock with a slot (180) provided on the beading (150) to restrict the one or more relative movements of the beading (150) with respect to the second wall (140);
• a guide rail (200) positioned adjacent to the second wall (140) and mechanically coupled to the elevator cabin (210), wherein the guide rail (200) is disposed at the fourth side (70), wherein the guide rail (200) is configured to guide an actuation of the elevator cabin (210);
• and
• a seal assembly (330) adapted to fit over a top portion of the elevator cabin (210), wherein the seal assembly (330) is configured to seal the elevator cabin (210) to reduce vibrations during upward and downward movement of the elevator cabin (210),
• wherein the seal assembly (330) comprises a depressurizing system configured to prevent the elevator cabin (210) from coming into force contact with the external cylinder (30) during upward movement and contribute to safety of an elevator operation.
