【技術分野】
本発明は，住宅等の建築物に用いられる窯業系建築板及びその施工構造に関する。
【０００２】
【従来技術】
近年，住宅等の外壁板となる窯業系建築板においては，造形性に優れた意匠効果を持たせるために，厚みの大きい板が広く用いられるようになっている。
ところで，窯業系建築板の取付方法においては，釘打ちによる方法と金具による方法とが一般的に知られている。
【０００３】
図１０，図１１に示すごとく，釘打ちによる取付方法は，窯業系建築板９の外観意匠面となる表面から直接釘３を打ち込む方法である。この方法においては，施工作業が簡単であり，施工に特殊な金具等を使用しないため，施工費用を最小限にすることができる。
しかしながら，図１０に示すごとく，厚みの大きい窯業系建築板の場合，釘３を下地材２１に打ち込んだ板裏面部分の一部９１が，打ち込みの衝撃により破損するおそれがある。また，図１１に示すように，窯業系建築板９の取り付け後に釘３の頭部３１が表面に露出し，外観意匠性を損ねる。そのため，その釘３の頭部３１を目立たなくするために補修塗装等を行う必要がある。
【０００４】
一方，金具による取付方法は，窯業系建築板を専用の金具を介して下地材に取り付ける方法である。この方法においては，外部からは金具が一切見えないので，外観意匠性に優れている。また，施工も比較的簡単であることから，近年普及してきている。
しかしながら，上記金具が多数必要になり，釘打ちによる取付方法に比べると，施工費用を多く要する。また，使用する窯業系建築板に合う専用の金具が限定されるため，窯業系建築板の板厚等の違いに合わせて金具も各種そろえる必要がある。
【０００５】
【解決しようとする課題】
本発明は，かかる従来の問題点に鑑みてなされたもので，施工が容易で，施工費用を低減させることができ，かつ外観意匠性にも優れた窯業系建築板の施工構造を提供しようとするものである。
【０００６】
【課題の解決手段】
請求項１の発明は，上実部と下実部とを有すると共に，上記下実部には，上記窯業系建築板を下地材に固定するための複数個の釘打ち部を有し，該釘打ち部には釘の頭部が入る凹陥部を設けてあり，一方，上記上実部の基端部の内壁側には内実部が設けてあると共に，上記内実部と上記上実部との間に嵌合凹部が設けてあり，また，上記下実部には，上記釘打ち部よりも段部側にコーキング材が打設されている窯業系建築板を用いて，該窯業系建築板を互いに隣接させて下地材に固定してなる施工構造であって，
上記窯業系建築板は，上記釘打ち部に釘を打ち込むことにより，上記下地材に固定してなると共に，上記釘の頭部は上記凹陥部内に入っており，
当該窯業系建築板における上記下実部の先端部と，当該窯業系建築板に隣接する他の窯業系建築板における内実部との間には，上記下実部の先端部に上記内実部を支承するための補助金具を配設してなり，
該補助金具は，上側に上側凹部を形成し下側に下側凹部を形成した断面Ｈ型形状を呈しており，
また，上記補助金具は，その片側の側壁を上側の上記窯業系建築板の上記嵌合凹部に嵌合させると共に，上記上側凹部によって上側の上記窯業系建築板の上記内実部を嵌合，支承し，上記下側凹部によって下側の上記窯業系建築板の上記下実先端部を嵌合してなり，
かつ，当該窯業系建築板の下実部と隣接する他の窯業系建築板の上実部との間は，上記コーキング材によりシールされていることを特徴とする窯業系建築板の施工構造にある。
【０００７】
本発明において最も注目すべきことは，上記窯業系建築板における上記下実部には，上記窯業系建築板を下地材に固定するための複数個の釘打ち部を有し，該釘打ち部には釘の頭部が入る凹陥部を設けてあることである。
【０００８】
次に，本発明の作用効果につき説明する。
本発明においては，上記窯業系建築板の下実部の上記釘打ち部には，釘の頭部が入る凹陥部が設けてある。そのため，当該窯業系建築板を釘により固定したとき釘の頭部は上記凹陥部に入る。
そのため，隣接する他の窯業系建築板が取り付けられるとき，上記釘の頭部が，上記他の窯業系建築板の上実部の裏面に干渉しない。
また，当該窯業系建築板の下実部の表面は，隣接する他の窯業系建築板の上実部によって覆われる。そのため，従来のように釘の頭部を補修塗装する必要がない。それ故，外観意匠性に優れると共に施工が容易である。
【０００９】
また，上記下実部には，上記釘打ち部よりも段部側にコーキング材が打設されている（図１参照）。そのため，外部からの雨水の浸入を防止することができる。
ここで，段部とは，隣接する窯業系建築板の上実部の先端部が対面するために，当該窯業系建築板の下実部の基端部に形成された段状の部分を言う。
【００１０】
また，本発明においては，窯業系建築板の下実部に釘を打ち込む。即ち，窯業系建築板の意匠面から裏面までの全体の厚みが，例えば２０ｍｍ〜２６ｍｍという大きな場合でも，下実部の厚みはその全体の厚みの半分ぐらいの１０ｍｍ〜１３ｍｍであるので，釘打ちによる方法が使用できる。それ故，窯業系建築板の施工が容易である。
また，窯業系建築板の施工時に，専用の施工金具を使用しないため，種類の異なる窯業系建築板ごとに，それに合わせた施工金具を準備する必要がない。それ故，施工費用を低減させることができ，様々な窯業系建築板に応用することができる。
【００１１】
以上，本発明によれば，施工が容易で，施工費用を低減させることができ，かつ外観意匠性にも優れた窯業系建築板の施工構造を提供することができる。
【００１４】
次に，上記窯業系建築板の施工方法の一例について説明する。
まず，釘によって打ち込まれる部分の下地材の表面に，防水テープを貼る。
次に，窯業系建築板を，防水テープの上から下地材に配置し，窯業系建築板の例えば上端の下実部に設けた凹陥部に釘の頭部が入るように釘を打ち込んで，窯業系建築板を下地材に取り付ける。
このとき，釘が防水テープ及び下地材及び防水紙を貫いて，建築物の躯体である柱に到達し，釘によって刺された部分の防水テープはその粘着性により釘にまとわりつく。
【００１５】
次に，既に取り付けた窯業系建築板の下実部の釘打ち部よりも段部側に設けられた帯状シール部に，コーキング材を供給する。
そして，隣接する他の窯業系建築板を，該窯業系建築板の上実部が既に取り付けた当該窯業系建築板の下実部を覆うようにして，下地材に取り付ける。
このとき，コーキング材が，当該窯業系建築板の下実部の表面と，後から取り付けた窯業系建築板の上実部の裏面との隙間に広がる。
【００１６】
また，上記釘打ち部に釘を打ち込むことにより，直接釘で窯業系建築板を下地材に固定しているので，窯業系建築板の横ずれの不具合発生を完全に抑制することができる。
また，上記窯業系建築板の構造に関しても説明したように，上記釘の頭部は下実部に設けられた上記凹陥部内に入っているので，上実部の裏面に特別な形状を有することなく，上実部を下実部に重ねるようにして施工ができる。
また，上記凹陥部は，上記段部から一定の距離に設けられているため，釘の打ち込みは，打ち込み位置を容易に決定できる専用の治具を取り付けて，ハンド式の釘打ち機等によっても行うことができる。なお，そのとき，上記段部を上記治具の位置決め用の端面として使用できる。
【００１７】
次に，請求項２に記載の発明のように，上記下実部と上記下地材との間には，防水テープを配置してなり，該防水テープを貫通して上記釘が下地材に固定されている施工構造であることが好ましい。
これにより，窯業系建築板と隣接する他の窯業系建築板との裏面接合部に形成される隙間からの雨水の漏水を防止することができる。
【００１８】
また，当該窯業系建築板における上記下実部の先端部と，当該窯業系建築板に隣接する他の窯業系建築板における内実部との間には，上記下実部の先端部に上記内実部を支承するための補助金具を配設する。
これにより，厚みの異なる窯業系建築板を隣接して施工することができる。
【００１９】
また，上記補助金具は，少なくとも上記下実部の先端部に嵌め込む嵌合部と，上記内実部を支承する支承部とを有する。
これにより，厚みの異なる窯業系建築板を隣接して施工することができると共に，安定して隣接する窯業系建築板を支承することができる。
【００２０】
次に，請求項３に記載の発明のように，上記窯業系建築板は，四方合決り構造であることが好ましい。
これにより，縦横目地溝部からの雨水の浸入等を防止することができ，四方に隣接させて窯業系建築板を容易に施工することができる。
【００２１】

【００３２】
次に，本発明の作用効果につき説明する。
本例においては，上記窯業系建築板１の下実部１２の上記釘打ち部１２１には，釘３の頭部３１が入る凹陥部１２２が設けてある。そのため，当該窯業系建築板１を釘３により固定したとき釘３の頭部３１は上記凹陥部１２２に入る。
そのため，隣接する他の窯業系建築板１が取り付けられるとき，上記釘３の頭部３１が，上記他の窯業系建築板１の上実部１１の裏面に干渉しない。
【００３３】
また，当該窯業系建築板１の下実部１２の表面は，隣接する他の窯業系建築板１の上実部１１によって覆われる。そのため，従来のように釘３の頭部３１を補修塗装する必要がない。それ故，外観意匠性に優れると共に施工が容易である。
また，上記下実部１２には，予めコーキング材４が帯状に打設されているので，外部からの雨水の浸入を防止することができる。
【００３４】
また，上記窯業系建築板１の意匠面から裏面までの全体の厚みが，例えば２０ｍｍ〜２６ｍｍという大きな場合でも，下実部１２の厚みはその全体の厚みの半分ぐらいの１０ｍｍ〜１３ｍｍであるので，釘打ちによる固定方法が可能である。

【００３７】
なお，本例においては，四方合決り構造の窯業系建築板１を用いているが，この他にも例えば，窯業系建築板１はその上側の辺にのみ下実部１２を設け，その下側の辺にのみ上実部１１を設けて，左右突き付け構造とすることもできる。
【００３８】
実施形態例２
本例は，図７〜図９に示すごとく，窯業系建築板１０における上記下実部１４の下実先端部１４１と，当該窯業系建築板１０の上側に隣接する窯業系建築板１００における内実部１３１との間に，上記下実先端部１４１と上記内実部１３１とを支承する断面Ｈ型形状の補助金具７を配設してなる例である。

【００３９】
次に，本例の窯業系建築板の施工構造について詳説する。
図８に示すごとく，当該窯業系建築板１０における下実部１４の下実先端部１４１には補助金具７の下側凹部７２が嵌合しており，補助金具７の上側凹部７１は上方に隣接する他の窯業系建築板１００における内実部１３１を嵌合，支承している。
また，補助金具７の片側の側壁７３は，上側の窯業系建築板１００における上実部１３と内実部１３１との間に形成された嵌合凹部１３５に嵌合している。
その他は，実施形態例１と同様である。
【００４０】
本例においては，厚みの異なる窯業系建築板１０，１００を上下に隣接して施工することができる。
即ち，補助金具７の片側の側壁７３は，上側に隣接する窯業系建築板１００の上記嵌合凹部１３５に嵌合し，窯業系建築板１００を意匠面の前後方向にガタツキのないように拘束する。そのため，窯業系建築板１００の内実部１３１の厚みを，補助金具７の上側凹部７１における両側壁７３の間に形成された幅よりも小さくすることができる。つまり，内実部１３１の厚みが小さいものを取り付けることが可能となる。
【００４１】
また，上記全体の厚みが小さい窯業系建築板１００の上側の辺の下実部には，窯業系建築板１００の下実部に合わせて下側凹部７２を２つに分割する中央壁７４を形成した補助金具７０を使用することができる（図７（ｂ）参照）。それ故，上記厚みの異なる窯業系建築板１０，１００を混合して使用することもできる。
その他，上記実施形態例１と同様の作用，効果を得ることができる。
【００４２】

【Technical field】
The present invention relates to a ceramic building plate used for a building such as a house and a construction structure thereof.
[0002]
[Prior art]
2. Description of the Related Art In recent years, in ceramic building boards serving as exterior wall boards for houses and the like, boards having a large thickness have been widely used in order to have a design effect excellent in formability.
By the way, as a method of attaching a ceramic building board, a method using nailing and a method using metal fittings are generally known.
[0003]
As shown in FIGS. 10 and 11, the nailing method is a method in which the nail 3 is driven directly from the surface of the ceramic building board 9 which is to be an external design surface. In this method, the construction work is simple, and special fittings and the like are not used for the construction, so that the construction cost can be minimized.
However, as shown in FIG. 10, in the case of a ceramic building plate having a large thickness, a part 91 of the back surface of the plate where the nail 3 is driven into the base material 21 may be damaged by the impact of the driving. In addition, as shown in FIG. 11, the head 31 of the nail 3 is exposed on the surface after the ceramic building board 9 is attached, thereby impairing the appearance design. Therefore, it is necessary to perform repair painting or the like to make the head 31 of the nail 3 inconspicuous.
[0004]
On the other hand, the mounting method using metal fittings is a method of mounting ceramic building boards to the base material through dedicated metal fittings. In this method, the metal fittings are not visible at all from the outside, so that the appearance is excellent. In addition, construction is relatively easy, and it has become popular in recent years.
However, a large number of the above-mentioned metal fittings are required, and the construction cost is higher than the mounting method by nailing. In addition, since the dedicated metal fittings that match the ceramic building boards to be used are limited, it is necessary to prepare various metal fittings according to differences in the thickness of the ceramic building boards.
[0005]
