Because at least one level difference is formed on the decorative surface, the strength is sufficiently reinforced to prevent warping, twisting, and
Pekotsuki can be prevented, and the decorative surface area will not become mountain-like. Since the male and female joints have the above-mentioned drop-in structure, it can be easily carried out by one person, and the joint width can be kept constant.
Moreover, it is highly waterproof. The board has a sanderch structure, which improves its strength. Since the shape of the step piece in the decorative surface part and the shape of the step piece in the joint part are made to be very similar, it is possible to create a unified horizontal line on the wall, give the wall a three-dimensional feel, and improve its aesthetic appearance. Since grooves and protrusions are formed on the upper surface of the insertion edge, rain is returned at the connection part of the board, and capillary phenomenon is prevented, thereby improving waterproofness. Since the boards are connected in a double structure, the engagement force is greatly improved. Since the core material holding piece is provided, the integration of the core material and the surface material is strengthened.
Since the core material clamping piece is provided, there is no leakage from the female connecting part side even if a material that discharges raw material, reacts, and foams as the core material is used. Since the board can be made wider, it is easier to construct, and the width of the material can be used more effectively, making it more economical. Since it has a recessed portion, there is no difference in height between each step piece. There are other effects.
