These include No. 11882 and Utsuko No. 54-26649. However, the biggest drawback of this type of board is that the decorative surface becomes mountain-like, and walls formed using it have the appearance of a continuous mountain. In other words, when the decorative surface of the board becomes mountain-like, it not only has poor aesthetics, but also is difficult to install, and there are disadvantages such as a lack of waterproofness at the connecting portion and the possibility of the board coming off. In addition, many of these types of boards have a hanging structure, which has the disadvantage of uneven joint width due to construction. Furthermore, the decorative surface of this type of board is flat (including embossed) by design, and
It was just a step or unevenness, lacking a three-dimensional effect, and the working width was small, so it had the disadvantage of lack of workability. In addition, boards of this kind that have a drop-in type connection structure are also known, but these have the drawbacks of lacking three-dimensionality, waterproofness, heat insulation, workability, and economic efficiency.

The width of the board is made wider, and the corners of the step are formed at acute or obtuse angles to make the step part more clear.In addition, in the female type connection part, the step at the connection part of the board is emphasized, and the corner of the step is formed at an acute angle or an obtuse angle. A decorative rib is provided to improve the waterproofness of the board, making it easier for one worker to install the board.
Moreover, it can be easily performed without requiring any skill.
Furthermore, it creates a rhythmic change in the wall surface, and in addition, a heat insulating material is also formed on the back of the extension part to strengthen the heat insulation of the board connection part, prevent deformation of the decorative surface, and improve waterproofness, three-dimensionality, and The present invention proposes a board with significantly improved engagement force.

る。 As mentioned above, according to the board according to the present invention,
Since at least one step is formed on the decorative surface, the strength is sufficiently reinforced, and even if the board is made wide, it looks like it is made up of multiple boards, so it does not look like a mountain. There is nothing to do. By creating a gap between the lower end of the stepped piece and the decorative piece in the decorative surface area, the difference in level becomes clear and the three-dimensional effect is strengthened. Moreover, when the board is installed, the appearance of the horizontal joint and the stepped part are very similar, making it possible to create a uniform pattern. A wall consisting of joints can be formed. Decorative ribs are formed on the female joints of the boards, improving waterproofness at the joints. Since the male and female connecting portions are formed in the above-mentioned drop-in structure, even one person can perform the work, and the joint width (horizontal) can be formed to be constant. No skill is required to connect the boards, and construction can be performed with extremely high efficiency. The board has a sanderch structure, which improves its strength. When a wall is formed from boards, there are changes in the step portions and side joints, and by creating periodic changes in the wall, it is possible to form a wall with a beautiful appearance and a rich three-dimensional effect. Since the board is wide, it is easy to install, and the width of the material can be used effectively, making it highly economical. The board is filled with a heat insulating material as a core material, and the side joints are double layers of heat insulating material, making it possible to form a wall with excellent heat insulation properties.
When synthetic resin foam is used as insulation material, it is lightweight,
It has excellent heat insulating properties and can be extremely easily formed into a single component by utilizing the self-adhesive properties of foaming without the need for adhesives. When the board is installed, a continuous triangular space is created between the board and the wall base, creating an air cycle effect.
