Description

TECHNICAL FIELD The present invention relates to a siding board (hereinafter simply referred to as a board) that forms a vertical or horizontal wall as an exterior material or an interior material of a building or a structure. It is a thing. More specifically, in addition to having unprecedented design,
The present invention relates to a board having excellent heat insulating property, fireproof property, waterproof property, airtightness, engaging force and strength.

[Conventional technology]

Conventionally, many boards have been marketed in which a thin metal plate is used as a surface material, male and female connecting portions are formed on both side edges in the longitudinal direction, and a synthetic resin foam and a back surface material are laminated on the back surface of the surface material.
Further, in this type of board, a core material is formed by bulging on the lower surface of the nail driving portion in order to enhance waterproofness and heat insulation of the joint portion. Also, by forming a makeup groove on the makeup surface,
Some have improved design and workability.

[Problems to be solved by the invention]

However, when the outer wall is formed by this kind of board, since the lower surface of the nail driving piece has a core material such as synthetic resin foam, an elastic core material such as synthetic resin foam is used. In this case, the nailing piece was peeled off due to the elasticity of the core material during nailing, making nailing difficult. Also, the nail driving piece and the core material bulging on the lower surface of the nail driving piece are destroyed by nailing, resulting in deterioration of waterproofness, heat insulation, and airtightness due to a difference in joint size and a decrease in engagement force. It was something that was done.
Furthermore, this type of board lacks the strength of the insertion edge, and the connecting portion between the insertion edge and the engaging groove is not provided with a shape that prevents the capillary phenomenon, and the decorative surface has the disadvantage of lacking designability. there were. In addition, using the same board vertically and horizontally has the drawback of poor workability and waterproofness. Also, the makeup groove and joints have the same color as the makeup surface, and dust accumulates in the groove,
There was a disadvantage that the dirt was noticeable.

[Means for solving problems]

In order to eliminate such defects, the present invention provides one or more special decorative grooves on the decorative surface, and has a shape in which the insertion edge is provided with waterproofing reinforcement and reinforcement.
This is a board which has a coating layer having a concealing power formed on the surface of the insertion edge and can be used for both design and engaging force and vertical and horizontal tension, and is easy to construct.
