It is possible to suppress the gap between the wood material 22 from being opened. That is, it is possible to prevent a gap from being formed between the first vertical winding material 21 and the second vertical winding material 22. As a result, it is possible to prevent rainwater from entering between the first vertical struts 21 and the second vertical struts 22 due to wind and rain blowing up along the roof surface.

  Further, in this connection structure, since the fixing plate 3 is provided not on the concave portion 23 but on the convex portion 24, the flow of rainwater flowing down the concave portion 23 is not hindered and a decrease in drainage can be suppressed.

  As described above, according to this connection structure, it is possible to connect the first vertical roofing material 21 and the second vertical winding material 22 in the roof gradient direction while ensuring high water-stopping properties. Therefore, according to this connection structure, the 1st vertical winding material 21 and the 2nd vertical winding material 22 can be made into the magnitude | size which can be conveyed with a truck etc., and can improve conveyance property and workability. .
