A structure for frame pieces of a pneumatic vacuum elevator is disclosed. The structure includes at least two horizontal arc pieces (30) and at least two vertical pieces (40) including a first arc end and a second arc end. Each of the first arc end and the second arc end include an angled cut profile. Each of the first arc end and the second arc end are adapted to receive a first coupling piece (100) at the angled cut profile. The first coupling piece (100) includes at least two holes (110). The at least two holes (110) are adapted to mechanically couple the at least two horizontal arc pieces (30) with the respective at least two vertical pieces (40) using a screw-fixing mechanism, upon receiving the respective at least two vertical pieces (40) at the angled cut profile. The at least two holes (110) are positioned at a first predefined position on the first coupling piece (100).
