A parking deck structure for a non-dodging three-dimensional (3D) parking garage is disclosed. The parking deck structure comprises a parking deck (18), a parking deck column (22), and a front roller (27), a rear roller (28) and side rollers (29) for supporting upward and downward movement of the parking deck (18) along a rotary column (17). The front roller (27) is mounted on the parking deck column (22), and the rear roller (28) is mounted on a rear elevating support (26). At both a left side and a right side of the parking deck column (22) is connected a wing plate (24, 25) respectively, and the side rollers (29) are mounted on the wing plates (24, 25) respectively. A side of each of the L-shaped wing plates (24, 25) that is away from the rotary column (17) is connected with the rear elevating support (26). With this arrangement, the parking deck structure of the present disclosure is simple in structure, has high bending resistance and a high capability to support the rollers, and is low in cost. Further, an end surface connecting plate (23) extending outwards is disposed at a lower end of the parking deck column (22), and the parking deck column (22) is joined to the parking deck (18) by means of the end surface connecting plate (23). Accordingly, the parking deck structure is easy to assemble and transport.
