Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a siding board that forms a vertical or horizontal wall as an exterior material or interior material of a building or structure. (hereinafter simply referred to as a board). More specifically, the present invention relates to a board whose decorative surface forms a wall with an unprecedented design.

[Conventional technology]

This kind of board is known in Japanese Utility Model Publication No. 50-895, Japanese Utility Model Publication No. 50-1522, Japanese Utility Model Publication No. 51-1138, and Japanese Utility Model Application Publication No. 54-7270.

[Problem that the invention attempts to solve]

However, in this type of board, since the decorative surface is not reinforced, there is a disadvantage that the board cannot be formed wide. In addition, decorative joints are formed in the joints of walls formed using this type of board, but since these decorative joints have a part of the insertion edge of the male connection part as the bottom surface,
Due to the engagement force between the boards, it was only possible to form a decorative joint width up to about 20m1+.

[Means for solving problems]

The present invention forms a plurality of decorative pieces by forming a stepped piece on the decorative surface part, forms a board with a wide width, improves workability and economical efficiency, and reduces the width of adjacent decorative pieces divided by the stepped piece to l.
:9 to 0.1, and a board with an improved design is proposed, which forms decorative joints of an unprecedented width in the wall body formed by the board.

．． It is divided into decorative pieces 2a and 2b of 1:1.

Therefore, the wall formed by the board A has a shadow created by the step piece 3 and an unprecedented three-dimensional effect due to the unprecedentedly large ratio of the decorative pieces 2a and 2b. Reference numeral 4.5 denotes side walls, which are formed by bending both longitudinal edges of the decorative surface portion 1 inwardly perpendicularly or obliquely. The male connecting part has an insertion edge 7 that projects outward from the lower end of the side wall 4, and a tongue piece 8 that is bent into a seam shape at the tip of the insertion edge 7.
The insertion edge 7 engages with an engagement groove 10 of the female type connecting part, which will be described later, and the tongue piece 8 prevents the tip of the insertion edge 7 from waving and prevents insertion into the engagement groove 10. In addition to making it easier to use, it also serves as a rain cover within the joint. Also tongue piece 8
This also serves to prevent workers from being injured by the tip of the insertion edge 7 when installing the board A. The main female type connecting part has an engaging groove 10 formed by bending the lower end of the side wall 5 inwardly and then outwardly to form a U-shaped cross section, and a lower edge 10a of the engaging groove 10 outwardly. Extended nailing piece 11 and nailing piece 1

Note that this type of additive may be surface-treated with a surfactant. Furthermore, as an example of synthetic resin foam,
These include polyurethane foam, polyimide foam, phenol foam, polyisocyanurate foam, etc.

In particular, it is preferable that this synthetic resin foam forms a carbonized layer under high heat. Note that the core material 13 can be filled with raw materials by discharging, molding, curing, self-adhesion, or
The molded body is attached using an adhesive. Although not shown, the core material 13 may bulge out below the nailing piece 11 to further strengthen the heat insulation, fireproofing, and soundproofing properties. Reference numeral 14 denotes a backing material, which covers at least the back surface of the core material 13 in the longitudinal direction with the self-adhesive properties of the core material 13 or with an adhesive interposed therebetween, and is mainly used for fireproofing, waterproofing, weather resistance, and aesthetics. It has at least one function of improving properties and strength.

Examples of materials include kraft paper, asbestos paper,
Waterproofed kraft paper, waterproofed asbestos paper,
It consists of a metal foil (Al11Pbs Cus Fe1 stainless steel), a glass fiber nonwoven fabric, a synthetic resin sheet, and a sheet-like material obtained by laminating or vapor-depositing one or more of these.
