Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a joint material that is used for a left and right connecting portion when an exterior material such as a side roofing material is used to form a roof or the like and to which a snow stop function is added.
[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 applied to roofing materials, there was a risk that the cover part would be slid in the longitudinal direction of the exterior material when the snow was removed in the snowy area, and the joint part would be exposed to the outside. . Moreover, the snow stop function was not added to this kind of connection structure.
[0004]
[Means for Solving the Problems]
In order to eliminate such drawbacks, the present invention is a narrow and narrow plate-like shape that protrudes outward in the middle to form a protruding portion, and the widthwise side end of the covering portion protrudes outward. The tip is extended inward, a locking part having a locking tongue formed in a substantially concave shape along the longitudinal direction is formed in the substantially central part, and the rising part that protrudes upward from the substantially central part of the mating part. The joint material formed from the part is provided.
