Description

[0001]
[Industrial application fields]
The present invention relates to a building board used as an outer wall material, for example.
[0002]
[Prior art]
In many cases, the surface of this type of building board is provided with a block-like pattern in which a plurality of convex blocks are arranged vertically and horizontally via a concave groove. Further, an upper solid part is formed at one joining edge of the building board, a lower solid part is formed at the other joining edge, and the pair of building boards is a lower solid part of one building board. They are joined by superimposing the solid part of the other building board on the part (for example, Japanese Utility Model Laid-Open No. 5-87122).
[0003]
[Problems to be solved by the invention]
In the above-mentioned building board, since the upper part is formed thin, the mechanical strength is small, and there is a possibility that breakage or chipping may occur. Further, there is a problem that the joints of the boards become conspicuous if the outer edges of the convex blocks of both building boards are aligned at the joint edge.
[0004]
[Means for Solving the Problems]
The present invention solves the above-mentioned conventional problems, and is a building board (1) having a block-like pattern (2) in which a plurality of convex blocks (5) are arranged vertically and horizontally on the surface via concave groove portions (3,4). The upper solid part (6) is formed at one joint end edge, and the lower solid part (7) is formed at the opposite other joint end edge, and the upper solid part (6) side is formed. By forming the all convex blocks (5) constituting the outermost convex block row (5C) across the plate body (1A) and the upper solid part (6), the upper real part (6) is reinforced. The building board (1) is provided.
All or part of the convex blocks (5) constituting the outermost convex block row (5C, 5D) at the edge of the upper solid portion (6) side and / or the lower solid portion (7) side is the convex block row (5C, 5D) is preferably arranged slightly shifted from the upper solid part (6) side outermost convex block row (5C) upper convex part (5) upper solid part (6) edge The deviation from (6A) is smaller than the deviation from the lower solid part (7) edge (7A) of the convex block (5) in the lower real part (7) side outermost convex block row (5D) or 0 It is desirable to be set to.
[0005]
[Action]
Convex blocks constituting the outermost convex block row (5C) on the joint edge side where the solid part (6) is formed in the block-like pattern (2) formed on the surface of the building board (1) If the whole of (5) is formed across the plate body (1A) and the upper solid part (6), the upper solid part (6) becomes the thickness of the convex block (5) and the mechanical strength is increased. improves.
At the edge of the upper solid part side and / or the lower solid part side, all or part of the convex blocks (5) constituting the outermost convex block row (5C, 5D) are transferred to the convex block row (5C, 5D). ), The width of the groove (4) located at the joint S between the plates changes, and the joint S becomes inconspicuous.
In this case, if the deviation from the upper solid part (6) edge (6A) of the convex block (5) in the outermost convex block row (5C) on the upper solid part (6) side is increased, that is, the convex block (5) If it is pulled deeply into the back (on the main body side), the exposed portion of the upper solid part (6) increases and the reinforcing effect decreases. However, in order to make the joint S between the plates inconspicuous, it is necessary that the width of the concave groove portion (4) in the joint S is greatly changed. Therefore, for the convex block (5) in the upper solid part side outermost convex block row (5C), the deviation from the upper solid part (6) edge (6A) is reduced or made zero, and instead the lower real part side outermost block The degree of change in the width of the concave groove portion (4) is increased by increasing the deviation of the convex block (5) of the outer convex block row (5D) from the lower solid portion (7) edge (7A).

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to one embodiment shown in FIGS. 1 to 4. The building board (1) is composed of a wood cement board which is a cement board in which, for example, wood pieces, wood pulp, wood fibers and the like are mixed as a wood reinforcing material, By embossing, a block-like pattern (2) in which a plurality of convex blocks (5) are arranged vertically and horizontally is formed on the surface through vertical and horizontal concave grooves (3,4). A real part (6) is formed, and a lower solid part (7) is formed at the other opposite joint edge. The upper surface (5A) of the convex block (5) is embossed with a fine uneven pattern (8) to form a natural stone-like or brick-like design. Further, the four-side peripheral surface of the convex block (5) ( 5B) is a slope. When the inclination of the peripheral surface (5B) is made gentle, the design is diversified and the fun is increased.
[0007]
The convex blocks (5) have various widths, heights and shapes arranged randomly, giving the design an irregular fun.
[0008]
In the upper solid part (6) side outermost convex block row (5C), as shown in FIGS. 2 and 3, the full convex block (5A) straddles the plate body (1A) and the upper solid part (6). ) Is formed and is reinforced by increasing the thickness of the upper solid part (6) by the thickness of the convex block (5). In the upper solid part (6) side outermost convex block row (5C), the convex part (5) (see FIG. 2) and the upper solid part (6 ) edge (convex block (5 slightly retract to the back from 6A)) (but see FIG. 3) are disposed in a substantially alternating, the drawing amount (displacement amount) d ₁ is convex block (5) It is set very slightly so as not to lower the reinforcing effect on the upper solid part (6).
[0009]
On the other hand, in the lower solid part (7) side outermost convex block row (5D), it does not affect the actual strength, so the convex block (5) with the outer edge aligned with the lower solid part (7) edge (7A) And the convex blocks (5) that are drawn in to the back to a certain extent are arranged almost alternately. If the amount of deviation from the lower real part of the convex block (5) (7) the edge (7A) and d _2, is d _2> d _1.
[0010]
In this embodiment, as shown in FIG. 4, the degree of change in the width of the groove (4) located at the joint S between the plates increases, and the width of the groove (4) changes. Since the continuity is broken, the joint S becomes inconspicuous.
[0011]
Other than the above embodiment, as shown in FIG. 5, the outer edges of some of the convex blocks (5) of the upper solid part (6) side outermost convex block row (5C) are connected to the upper solid part (6) edge (6A ). In this case, in the plate joint, there is a portion where the outer edge of the convex block (5) on the outermost side of the joining side of one plate and the outer edge of the convex block (5) on the outermost side of the joining side of the other plate, As described above, the peripheral edge surface (5B) of the four sides of the convex block (5) is an inclined surface. It is secured and does not become 0.
[0012]
【The invention's effect】
In the present invention, since the upper solid part of the building board is reinforced by the block-shaped convex portions, the strength of the upper solid part is improved, and breakage, chipping, and the like of the upper real part are reliably prevented.
