PROBLEM TO BE SOLVED: To provide a floor structure for an ice rink to construct the ice rink capable of stably keeping a freezing state with a comparatively small man-hour and a short construction time.SOLUTION: In a floor structure for an ice rink in which a plurality of unit floor materials 2 composed of extruded shapes 2, 2a of aluminum alloy, and including horizontal plates 6 and refrigerant pipe sections 7 disposed below the horizontal plates 6 on a cross-section orthogonal to an extruding direction, are connected to each other along two directions of the extruding direction and the direction orthogonal to the extruding direction, removed sections k1 formed by removing a part of the horizontal plates 6 excluding the pipe sections 7, are formed in adjacent to each other on end sections of the pair of unit floor materials 2, 2a adjacent to each other along the extruding direction, and end sections of the pair of adjacent pipe sections 7 extending in the pair of removed sections k1, k1, are connected by a pipe joint J1 composed of a male screw sleeve 23 and a female screw sleeve 25 threadably connected with each other along the axial direction, at an outer side of the end sections. |
