PROBLEM TO BE SOLVED: To contrive a barrier-free structure by eliminating a step by retrofitting a frame material including a tread wall inclined downward toward a washing place floor face from the upper end of the washing place side of a door frame on an internal corner between the door frame of the lower face of an entrance and the floor face of a washing place. SOLUTION: On an internal corner between a door frame 7 and the floor face of a washing place 12, a frame material 16 comprising the extrusion shape of aluminum alloy and including a tread wall 17 inclined downward toward the floor face 12 of a washing place from the upper end of the side of the washing place 3 of a door frame is retrofitted. Then, after the base end 25a of a stainless steel-made attaching piece 25 is supported to the side of the washing place 3 in the form of slip-off stop, the frame material 16 is attached to a vertical wall 24 by screwing the tread wall 17 on the edge part 25b of the attaching piece 25. In addition, a slip stop 21 comprising a plurality of projections is integrally projected and formed, and the lower face of the bottom wall 19 of the frame material 16 is seated on the floor face 12 of the washing place through a rubber-made elastic member 23. Thereby it can deal with the slight difference of the size of the door frame 7 and a step (h) of various shapes, and safety can be secured. |
