Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a siding board (hereinafter simply referred to as a board) useful for forming horizontal walls for the interior and exterior of buildings and structures.

Examples of this type of board that have been used in the past include ■Special Publication No. 51-29339, and ■Jet Publication No. 51-1188.
No. 2, @Jitko No. 54-26649, etc. 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 has disadvantages such as difficulty in construction, lack of waterproofness at the connecting portion, and the possibility of separation. In addition, this type of board has many hook structures, and has the disadvantage that the width of the joints is uneven due to construction. Furthermore, this type of board has a flat decorative surface (
(including embossing), and it is merely a step or unevenness, lacking a three-dimensional effect, and the width of the gap is small, resulting in a disadvantage of poor workability. In addition, boards of this type that have a drop-in type connection structure are also known, but these have the disadvantages of lacking three-dimensionality, waterproofness, heat insulation, workability, and economic efficiency.

Furthermore, there is a drawback that manufacturing is not easy unless either the heat insulating material or the surface material is horizontal.

In order to eliminate such drawbacks, the present invention forms the decorative surface part in a step-like manner, and the corners of the steps are formed at acute angles or obtuse angles to make the step portion more clear, and when the boards are connected. The appearance of the joints in the male and female connecting parts that are formed is structured to closely resemble the step appearance of the decorative surface part, and the construction of the board is easy and can be done by one worker without the need for skill. Moreover, the present invention proposes a board that has a uniform horizontal joint width, is easy to manufacture, does not cause deformation of the decorative surface, and is waterproof and has a three-dimensional effect.

The board according to the present invention will be described below with reference to the drawings. In other words, as shown in Figure 1, board A is made of, for example, surface-treated steel sheets, steel sheets plated with zinc/Ninkel alloy, aluminum/zinc alloy plated steel sheets (product names: Galfan, Galvalume steel sheet, Super Zinc), Roll metal plates (including flat plates and embossed plates) made of one type of aluminum plate, aluminum alloy plate, copper plate, etc.
Alternatively, a sandwich structure is obtained by integrally filling a heat insulating material 23 between the surface material 22 and the surface material 22 formed by press molding or extrusion molding or the like as shown in FIG. It is. To explain further, the surface material is composed of a long decorative surface part 1, a male connecting part side, a female connecting part side, and a gutter-like part 21 filled with a heat insulating material 23. In other words, the decorative surface section has at least one step formed at an arbitrary position (in the center in the figure) on the surface of the long plate material, parallel to the longitudinal direction of the surface, as shown in the figure, and its lower end is turned outward. It is composed of a plurality of long oblique decorative pieces 4.5 (hereinafter simply referred to as decorative pieces) which are folded back and sectioned. The above-mentioned decorative surface mainly forms the surface of the surface material in a slanted step shape to promote a three-dimensional effect.
