PROBLEM TO BE SOLVED: To provide a simply-structured platform door structure that can be installed in an existing earth-fill platform, can achieve improvement in load-bearing performance by a simple structure, and can reduce restrictions associated with installation work.SOLUTION: A platform door structure is provided with: doors 26; partition walls 27; and a support structure 23 having an upper support 28 and a lower support 29 and supporting the doors 26 and the partition walls 27. The upper support 28 extends in the vertical direction along a surface direction where the doors move when the doors 26 are opened and closed and receives loads from the doors 26 and the partition walls 27. The lower support 29 is installed while being embedded into the ground at a platform foundation below a platform floor 102. The lower support 29 has a horizontal embedded part 30 fixed to the upper support 28 and extending in parallel with the platform floor 102, and a vertical embedded part 31 orthogonal to the horizontal embedded part 30 and extending vertically downward. |
