2. Description of the Related Art Conventionally, as shown in FIG. 4, a support metal fitting 2 attached to a roof substrate 1 such as a purlin 11 using a channel material has an end portion 4a of one roof plate 3a and the other roof plate 3b. In the connecting structure of the roof plates in which the end portions 4b of the other roof plates are connected and supported by the support fitting 2, the end portions 4b of the other roof plate 3b are overlapped on the end portions 4a of the one roof plate 3a, The bolt 7 is threaded into the support fitting 2 by penetrating both of them. In FIG. 4, 8 is a cap.

[0003]

However, in such a connection structure, the roof plates 3a and 3b are connected only by the connection by the bolts 7, and the roof plates 3a and 3b are connected.
