Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is used for the left and right connecting parts when forming roofs and wall bodies using exterior materials such as horizontal roofing materials or laterally extending outer wall materials, and also used as a snow stop with a snow stop function added. The present invention relates to a waterproof joint 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 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. A waterproof joint material having a locking portion having a locking tongue piece extending in the inner direction and having a locking tongue piece formed in a substantially concave shape along the longitudinal direction at a substantially central portion; a horizontal planar engaging piece; The snow piece formed from a rising piece projecting upward from the center part of the joint piece and a snow stopper part projecting outward from one end of the rising piece. The present invention provides a snow joint-use waterproof joint material in which a piece is engaged and integrated.
