I was thinking about the slopes too, but they just don't fit the dimensions especially if the slope rail have legs as they appear to float above the ground.
These are 12 レールおさえ, they are rail connectors that have to be placed on rails that are on top of the piers or below the piers if they want to slope up. If rails are placed on the piers without the connectors, the rails will wobble and slip off the piers.
