BACKGROUND OF THE INVENTION
The present invention relates to a joint material used for left and right connecting portions when a roof is formed using a roofing roof material.
[0002]
[Prior art]
Conventionally, the connection structure when constructing exterior materials such as horizontal roofing materials and lateral wall materials is as follows: (1) A structure in which both side edges of the exterior material are bent in a spiral shape and joined together, 2) A structure in which the side edges of the exterior material are sandwiched between the top and bottom of the siding board and the cover material, and (3) a structure in which the exterior materials are simply overlapped.
[0003]
[Problems to be solved by the invention]
However, in these structures, {circle over (3)} is inferior in waterproofness, and {circle over (1)} and {circle over (3)} are disadvantageous in that the steps are uneven due to the overlap of the exterior materials, leading to a decrease in design. In (2), especially when it is applied to the roofing material, there was a risk that the joint part would be exposed to the outside by sliding the cover material in the longitudinal direction of the exterior material when removing snow in the snowy region. . Moreover, the protruding member function was not added to this type of connection structure.
