PROBLEM TO BE SOLVED: To provide a structure of a roof-tile unit body which is economical and can enhance the effect of preventing rainwater from flowing into a building through a gap in a joint of roof-tile unit bodies.SOLUTION: A structure of a roof-tile unit body has four edges. A continuous arc surface which is recessed inward in the direction from an edge to the opposite edge is formed on the upper side of the roof-tile unit body, and a blade extends upward at the opposite edge. A joint member is arranged at each edge. Therefore, each roof-tile unit body can be connected with other roof-tile unit bodies having the same structure. When each roof-tile unit body is connected, the edges of the roof-tile unit body are arranged to overlap the blades of the other roof-tile unit bodies. A roof can be constructed by connecting two roof-tile unit bodies having the same structure with each other by each joint member, and further connecting multiple roof-tile unit bodies.SELECTED DRAWING: Figure 1 |
