Description
【0001】
【産業上の利用分野】
本発明は例えば外壁材として使用される建築板に関するものである。
【0002】
【従来の技術】
この種の建築板の表面には凹溝部を介して凸ブロックの複数個を縦横に配したブロック調模様が付されている場合が多い。また該建築板の一方の接合端縁部には上実部が形成されており、他方の接合端縁部には下実部が形成されおり、一対の建築板は一方の建築板の下実部上に他方の建築板の上実部を重ねることによって接合される(例えば実開平5−87122号)。
【0003】
【発明が解決しようとする課題】
上記建築板において、上実部は肉薄に形成されているので機械的強度が小さく、折損や欠けが発生するおそれがある。更に接合端縁部において、両方の建築板の凸ブロックの外側端縁が一直線に揃うと、板の継目が目立ってしまうと云う問題点もある。
【0004】
【課題を解決するための手段】
本発明は上記従来の課題を解決し、表面に凹溝部(3,4) を介して凸ブロック(5) の複数個を縦横に配したブロック調模様(2) を有する建築板(1) であって、一方の接合端縁部には上実部(6) が形成され、相対する他方の接合端縁部には下実部(7) が形成されおり、該上実部(6) 側の最外凸ブロック列(5C)を構成する全凸ブロック(5) を、板本体(1A)と該上実部(6) とにまたがって形成することによって該上実部(6) が補強されている建築板(1) を提供するものである。
上実部(6) 側および/または下実部(7) 側端縁部において、最外凸ブロック列(5C,5D) を構成する凸ブロック(5) の全部または一部は該凸ブロック列(5C,5D) に対して若干ずらして配列されていることが望ましく、更に上実部(6) 側最外凸ブロック列(5C)における凸ブロック(5) の上実部(6) 端縁(6A)からのずれは、下実部(7) 側最外凸ブロック列(5D)における凸ブロック(5) の下実部(7) 端縁(7A)からのずれよりも小さいかまたは0に設定されていることが望ましい。
【0005】
【作用】
建築板(1) の表面に形成されているブロック調模様(2) において、上実部(6) が形成されている接合端縁部側の最外凸ブロック列(5C)を構成する凸ブロック(5) の全部を板本体(1A)と該上実部(6) とにまたがって形成すれば、上実部(6) は該凸ブロック(5) 分肉厚になって機械的強度が向上する。
上実部側および/または下実部側の端縁部において、最外凸ブロック列(5C,5D)を構成する凸ブロック(5) の全部または一部を、該凸ブロック列(5C,5D) に対して若干ずらして配列すれば、板と板との継目Sに位置する凹溝部(4) の巾が変化することになり、継目Sが目立たなくなる。
この場合、上実部(6) 側最外凸ブロック列(5C)における凸ブロック(5) の上実部(6) 端縁(6A)からのずれを大きくすると、即ち凸ブロック(5) を大きく奥(本体側)に引込ませると、上実部(6) の露出部分が増大して補強効果が低下する。しかし板と板との継目Sを目立たなくさせるには、該継目Sにある凹溝部(4) の巾が大きく変化することが必要である。そこで上実部側最外凸ブロック列(5C)の凸ブロック(5) については上実部(6) 端縁(6A)からのずれを小さくするか0にし、その代りに下実部側最外凸ブロック列(5D)の凸ブロック(5) の下実部(7) 端縁(7A)からのずれを大きくして該凹溝部(4) の巾の変化の度合を大きくする。
【0006】
【発明の実施の形態】
本発明を図1〜図4に示す一実施例によって説明すれば、建築板(1) は例えば木片、木質パルプ、木質繊維等を木質補強材として混合したセメント板である木質セメント板からなり、エンボス加工によって表面には縦横凹溝部(3,4) を介して凸ブロック(5) の複数個を縦横に配したブロック調模様(2) が形成され、また一方の接合端縁部には上実部(6) が形成され、相対する他方の接合端縁部には下実部(7) が形成されている。該凸ブロック(5) の上面(5A)にはエンボス加工によって微細凹凸模様(8) が付されて天然石調あるいはれんが調の意匠となっており、更に凸ブロック(5) の4辺周縁面(5B)は斜面とされている。該周縁面(5B)の傾斜に緩急を持たせると意匠が多様化して面白味が増す。
【0007】
該凸ブロック(5) は各種横巾、縦巾、形状のものがランダム状に配置され、意匠に不規則な面白味を与えている。
【0008】
上実部(6) 側最外凸ブロック列(5C)にあっては、図2および図3に示すように板本体(1A)と上実部(6) とにまたがって全凸ブロック(5) が形成され、該上実部(6) 厚みを該凸ブロック(5) の厚みによって増大させることにより補強している。該上実部(6) 側最外凸ブロック列(5C)においては、上実部(6) 端縁(6A)に外縁を接する凸ブロック(5) (図2参照)と上実部(6) 端縁(6A)から若干奥に引込ませた凸ブロック(5) (図3参照)が略交互に配されているが、この引込み量(ずれ量)d1 は該凸ブロック(5) の上実部(6) に対する補強効果を低下させないよう、極く僅かに設定されている。
【0009】
一方下実部(7) 側最外凸ブロック列(5D)にあっては、実の強度に影響しないので、外縁を下実部(7) 端縁(7A)に揃えた凸ブロック(5) と、奥にある程度大きく引込ませた凸ブロック(5) とを略交互に配する。この凸ブロック(5) の下実部(7) 端縁(7A)からのずれ量をd2 とすれば、d2 >d1 である。
【0010】
この実施例では、図4に示すように板と板との継目Sに位置する該凹溝(4) の巾の変化の度合が大きくなり、該凹溝(4) の巾が変化する部分で連続性が絶たれるため、継目Sが目立たなくなる。
【0011】
上記実施例以外、図5に示すように上実部(6) 側最外凸ブロック列(5C)の凸ブロック(5) のいくつかのものゝ外縁を上実部(6) 端縁(6A)に接するようにしてもよい。この場合板接合部において、一方の板の接合側最外列の凸ブロック(5) 外縁と他方の板の接合側最外列の凸ブロック(5) の外縁とが直接接する部分があるが、前記したように該凸ブロック(5) の4辺周縁面(5B)は斜面になっているので、凸ブロック(5) 相互が直接接しても、この部分の横凹溝(4) の巾は確保され0にならない。
【0012】
【発明の効果】
本発明にあっては、建築板の上実部がブロック調模様の凸部によって補強されるので、上実部の強度が向上し、上実部の折損、欠け等が確実に防止される。

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).
[0006]
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.
