[Problem that the idea aims to solve]

However, the above board had various problems. That is, (A) When rainwater is blown away by the wind, the board (clapboard) is simply a series of flat plates. Due to the closed structure, rainwater leaks to the back side, corroding the rim and pillars, and causing damp indoors and closets. It had some drawbacks that made me feel bad. Also, in the case of the board in (B), the slope of the lower edge rises. Due to its long length, it is weak in tensile force and can only form an exterior without joints. It was profitable. What's more, even though the exterior was originally without joints, there were no joints due to the skill of the builder. However, the exterior is made up of joints of varying widths, and it is difficult to stand up during construction. There was a risk of injury at the edge. Furthermore, the board in (C) has a complicated side shape. The drawback was that it was difficult to mold and expensive.

[Means to solve the problem]

In order to eliminate the above-mentioned drawbacks, the present invention has a female connecting part on one end edge of the decorative surface, and a female-type connecting part on the other end edge. At the same time, the back material is made to protrude outward, and the protruding piece of the male type connection part is formed. A raised piece is provided at the lower end, and the lower end of the raised piece is bent inward to form a core material holding piece. In addition to strengthening the integration of the surface material and core material, the lower edge of the engagement groove of the female type connection part is A step piece is provided so that the core material holding piece of the male connection part is placed, and the tip of the step piece is Bend the end outward parallel to the decorative surface to form an extension, and add reinforcement and bulk to the tip of the extension. By forming barbed pieces, the adhesive area between the wall base and surface material is reduced, and the bulk of the male connection part is reduced. A space is formed between the raised piece and the step of the female type connecting part to prevent capillary phenomenon and the connecting part In addition, when this board is used as a horizontal covering, it is easy to install. It is a drop-in type that can be done by one worker and does not require any skill. We are proposing a board that can also be used as a tension material.
