Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to siding boards (for forming vertical or horizontal wall bodies) as exterior materials or interior materials of buildings and structures.
(hereinafter simply referred to as a board). More specifically, the present invention relates to a board that can be used as an outer wall with an air cycle structure by simply fixing it on a building frame.

[Conventional technology]

Conventionally, a thin metal plate was used as the surface material, and male,
A female connecting part is formed, and a synthetic resin foam is placed on the back side of the surface material.
Many boards with laminated backing materials are covered. In order to form a ventilation path for air circulation between the outer wall and the body of this type of board, a rim is required when it is laid horizontally, and a concave recess is formed in the core of the board when it is laid vertically. It was formed in a similar manner. However, even if formed in this way, air circulation between the furring edges would be lost during horizontal tensioning. For this reason, there are parts of the entire outer wall where air circulation is obstructed, which has the disadvantage of corrosion due to dew condensation. In addition, in order to circulate air throughout the wall in both vertical and horizontal installations, it was necessary at least to form a rim and a concave groove in the board. Furthermore, it has not been easy to form concave grooves in the core material of the board due to the physical properties of the core material.

(Object of the Invention) In order to eliminate such drawbacks, the present invention forms a stepped piece that protrudes inward from the core material at the connecting part on the side where the board is fixed, and a plurality of ventilation holes are formed in this stepped piece. This paper proposes a board that can create a space that communicates the entire inside of the outer wall without providing a rim.
