Description

【０００１】
【発明の属する技術分野】
本発明は，建物におけるベランダ等のオーバーハング部の前方下端部に配設されるオーバーハング部材に関する。
【０００２】
【従来の技術】
従来より，図１３に示すごとく，建物におけるベランダ等のオーバーハング部の前方壁面に，外壁板５を配設してなる垂れ壁仕様のオーバーハング部施工構造８がある。
上記外壁板５は，上記オーバーハング部の構造躯体４１に，縦胴縁等の下地材４２，通気用スペーサ４６を介して固定されている。また，上記オーバーハング部の底部には，軒天材４３が配設されている。
【０００３】
ところが，上記オーバーハング部施工構造８は，斜め前方下方から，即ち屋外から通常の視線角度で見上げたとき，上記外壁板５の下辺部５３が見えてしまう。また，上記オーバーハング部の前方壁面を構成する上記外壁板５の外壁意匠面５１が，下端部で突然途切れてしまう状態となり，外観意匠性が低下するおそれがある。
【０００４】
かかる観点から，図１４に示すごとく，上記オーバーハング部の前方下端部に，縦断面Ｌ字形状のオーバーハング部材９を配設したオーバーハング部施工構造８０がある。これにより，上記オーバーハング部の前方下端部においても，上記外壁板５の外壁意匠面５１と同様の意匠面９５を構成することができ，オーバーハング部施工構造８０の外観意匠性を向上させることができる。
【０００５】
該オーバーハング部材９は，例えば以下のごとく製造する。
まず，図１５に示すごとく，窯業系外壁板などの板材９１０を切断して，適当な大きさに板片９１を切り出す。次いで，図１６に示すごとく，該板片９１の一方の側端部９１１を斜めに切り落し，表側面９１２及び裏側面９１３に対して約４５°の角度をなす切断面９１４を形成する。また，表側面９１２の端部９１６についても，欠け防止のため，面取りしておく。
【０００６】
次いで，図１７，図１８に示すごとく，２枚の上記板片９１の上記切断面９１４同士を突き合せ，２枚の板片９１の表側面９１２が略直角となるように接合する。このとき，２枚の板片９１の上記切断面９１４の間には，接着剤９２を介在させる。これにより，上記２枚の板片９１を接着する。
また，上記２枚の板片９１の接合部９３には，タッカー９４を打ち込み，接合強度を確保する。
次いで，図１９に示すごとく，上記接合部９３の外側角部９３１を面取り切断し，該外側角部９３１の欠けを防止すると共に外観意匠性を向上させる。
【０００７】
【発明が解決しようとする課題】
しかしながら，上記従来のオーバーハング部材９は，上述のごとく，接着剤９２を用いて２枚の板片９１を接着する。そのため，接着養生の必要があり，製造に時間がかかる。また，２枚の板片９１の突合せ角度（例えば略９０°）を保持した状態で乾燥させるための保持治具が必要である。
【０００８】
また，上記接着剤９２が接合部９３からはみ出すこともあり，オーバーハング部材９の外観意匠性を低下させるおそれがある。それ故，この場合には，接着養生後に，はみ出した接着剤９２を削り取る必要がある。
また，上述のごとく，上記接合部９３にタッカー９４を打ったり，上記接合部９３の外側角部９３１を面取り切断する必要もある。そして，面取り面を後から補修塗装する必要もある。
【０００９】
更には，上記板片９１の表側面９１２に柄模様が形成されている場合に，その柄模様が上記接合部９３の両側においてずれると，違和感を生じ，オーバーハング部材９の外観意匠性が低下するおそれがある。
また，それ故，２枚の板片９１を接合するにあたっては，互いの柄模様がずれないよう位置合わせを慎重に行う必要がある。
【００１０】
また，上記オーバーハング部施工構造は，前方下端部が略直角状に形成されるため，緩やかな外観を表出することは困難であり，場合によっては外観意匠性を低下させる原因となる。
【００１１】
本発明は，かかる従来の問題点に鑑みてなされたもので，製造容易，安価かつ外観意匠性に優れたオーバーハング部材及びこれを用いたオーバーハング部施工構造を提供しようとするものである。
【００１２】

【００２５】
また，上記上方脚板部は，上記固定板部との間に，前方へ突出した横目地用突出部を設けてなる。
これにより，上記面取本体を，取付板における正確な位置に固定することができる。また，上記オーバーハング部材を施工するにあたり，該オーバーハング部材の上方に配設される外壁板を正確な位置に施工することが容易となる。
【００２６】
次に，上記第２の発明（請求項５）において，上記オーバーハング部材の面取本体は，上記外壁板と同質の材料からなることが好ましい。これにより，上記オーバーハング部において，外壁板とオーバーハング部材とが連続した外観を表出し，より外観意匠性に優れたオーバーハング部施工構造を得ることができる。

【００３７】
次に，上記オーバーハング部材１を用いた，本例のオーバーハング部施工構造４につき説明する。
該オーバーハング部施工構造４は，図１に示すごとく，上記オーバーハング部の構造躯体４１に下地材４２を介して上記オーバーハング部材１及び該オーバーハング部材１の上方に配された外壁板５とを留め付けてなると共に，上記構造躯体４１の底面に軒天材４３を配設してなる。
【００３８】
上記オーバーハング部材１は，上記取付板３の上記上方脚板部３２において上記構造躯体４１に固定されていると共に，上記後方脚板部３３によって，上記軒天材４３の前端部４３２を下方から被っている。
また，上記面取本体２と上記外壁板５の外壁側端面５３との間には，目地処理材４７が配設してある。即ち，上記横目地用突出部３５の前面にボンドブレーカを貼着して，その上（面取本体２と外壁板５との間の隙間部）に適正な量の目地処理材４７を充填してある。該目地処理材４７としては，シーリング材を用いている。
【００３９】

【００４０】
また，上記取付板３２の上方脚板部３２の前方には，上記外壁板５が釘４５によって上記横胴縁３２に固定されている。
上記通気用スペーサ４６は，図８に示すごとく，上下方向に貫通した通気セル４６１を複数有している。
【００４１】
また，上記後方脚板部３３に立設された軒天当接板部３４には，上記軒天材４３の前端面４３１を当接させている。なお，該前端面４３１は，必ずしも上記軒天当接板部３４に当接させる必要はない。
上記上方脚板部３３における横目地用突出部３５は，上記面取本体２の上端面２２１と上記外壁板５の下辺部５３との間に配置されている。即ち，上記横目地用突出部３５の上面３５３は，上記外壁板５の下辺部５３に当接し，上記横目地用突出部３５の下面３５２は，上記面取本体２の上端面２２１に当接している。
【００４２】
また，上記オーバーハング部材１の面取本体２は，上記外壁板５と同質の材料からなる。また，本例において，上記面取本体２は窯業系材料からなるが，樹脂等の他の材料を用いることもできる。
【００４３】
また，上記オーバーハング部の上下左右に関するコーナー部に，上記オーバーハング部材１を配設するに当っては，該オーバーハング部材１を，図６に示すごとく，下面視略Ｌ字状に配設する。即ち，該オーバーハング部材１の一端を略４５°に切断したものを，その切断面１２同士を突き合わせるようにして配設する。
【００４４】
なお，図７に示すごとく，上記取付板３を予めＬ字状に形成しておいて，その固定板部３１に上記面取本体２を固定してもよい。この場合，通常の取付板３（図５）の横目地用突出部３５の部分を残して切断して切込みを入れ，残った上記横目地用突出部３５において，折り曲げることにより，上記略Ｌ字状の取付板３を得ることもできる。
【００４５】
次に，本例の作用効果につき説明する。
上記面取本体２は，上述のごとく一体的に形成されている。そのため，上記面取本体２の製造にあたっては，接合，接着の工程を必要としない。それ故，上記面取本体２は製造が容易であり，その結果，オーバーハング部材１の製造が容易となる。
【００４６】
また，上記面取本体２は一体的に形成され，接合部を有しないため，外観意匠性に優れている。
また，上記オーバーハング部材１は上記取付板３を有するため，該取付板３を介して上記オーバーハング部材１を上記オーバーハング部に容易に施工することができる。これにより，上記オーバーハング部施工構造４を安価に得ることが可能となる。
【００４７】
また，上記面取本体２は，上記面取意匠面２１を有しているため，該面取意匠面２１によって，上記オーバーハング部の前方下端部を面取りしたような外観に形成することができる（図２）。それ故，緩やかな印象を与える外観意匠性の高いオーバーハング部施工構造４を構築することができる。
【００４８】
また，図１に示すごとく，上記取付板３の後方脚板部３３は，上記軒天材４３の前端部４３２を下方から被っている。そのため，上記軒天材４３の前端部４３２が外部から見えず，外観意匠性に優れたオーバーハング部施工構造４を得ることができる。
【００４９】
また，上記後方脚板部３３は上記軒天当接板部３４を立設してなり，該軒天当接板部３４に上記軒天材４３の前端面４３１を当接させてなる。そのため，上記軒天材４３を上記オーバーハング部材１の取付け後に，容易に固定することができる。また，軒天材４３が少々短くても，取付板３によって前端部４３２を被覆することができる。
【００５０】
また，上記後方脚板部３３は，上記開口穴３３１を形成してなるため，図１に示すごとく，該開口穴３３１から上記外壁板５の後方へ空気６を導入することができる。この空気６は，上記通気用スペーサ４６の通気セル４６１（図８）を通って外壁板５の後方に導入される。これにより，オーバーハング部施工構造４の通気性を確保することができる。また，万一上記外壁板５の後方に雨水が浸入した場合にも，この雨水を上記開口穴３３１から排出することができる。
これにより，上記外壁板５，構造躯体４１等の腐食，劣化を防ぐことができ，耐久性に優れたオーバーハング部施工構造４を得ることができる。
【００５１】
また，上記上方脚板部３３は，上記横目地用突出部３５を設けてなり，該横目地用突出部３５は，図１に示すごとく，上記面取本体２の上端面２２１と上記外壁板５の下辺部５３との間に配置されている。そのため，上記オーバーハング部材１と，その上方に配設される外壁板５との間隔を一定にすることができる。また，上記横目地用突出部３５の前面にボンドブレーカを介して，適正な量の目地処理材４７を充填することができる。
【００５２】
また，上記面取意匠面２１は，上記前端面２１１を有しているため，図１に示すごとく，面取本体２の面取意匠面２１と，これに隣接して配される外壁板５の外壁意匠面５１との面合わせをすることができる。それ故，一層外観意匠性に優れたオーバーハング部施工構造４を得ることができる。
【００５３】
また，上記オーバーハング部材１の面取本体２は，上記外壁板５と同質の材料からなる。そのため，上記オーバーハング部において，外壁板５とオーバーハング部材１とが連続した外観を表出し，より外観意匠性に優れたオーバーハング部施工構造４を得ることができる。
【００５４】
以上のごとく，本例によれば，製造容易かつ外観意匠性に優れたオーバーハング部材及びオーバーハング部施工構造を提供することができる。
【００５５】
（実施例２）
本例は，図９，図１０に示すごとく，取付板３の後方脚板部３３の上方にソケット部３６を形成してなるオーバーハング部材１の例である。そして，これを用いたオーバーハング部施工構造４は，図９に示すごとく，上記ソケット部３６に軒天材４３の前端部４３２を収容してなる。
【００５６】
即ち，図１０に示すごとく，上記ソケット部３６は，上記後方脚板部３３の後端から前方へ折り返された底板部３６１と，該底板部３６１の前端から上方へ立設した前板部３６２と，該前板部３６２の上端から後方へ屈曲した上板部３６３とによって形成されている。
その他は，実施例１と同様である。
【００５７】
この場合には，上記軒天材４３が，上記ソケット部３６を介して上記オーバーハング部材１の後方脚板部３３を支持することとなるため，上記オーバーハング部材１の固定力が向上する。また，上記軒天材４３の前端面４３１の位置が多少前後にずれても，外観等に影響を与えることがないという利点もある。
その他，実施例１と同様の作用効果を有する。
【００５８】
（実施例３）
本例は，図１１に示すごとく，面取本体２の背面２２を，互いに直交する上端面２２１と後端面２２２とによって形成したオーバーハング部材１の例である。該オーバーハング部材１における取付板３の固定板部３１は，上記面取本体２の背面２２の形状に合わせた形状となっている。即ち，上記固定板部３１は，上記面取本体２の上端面２２１に固定する水平板部３１２と，後端面２２２に固定する鉛直板部３１３とからなる。
【００５９】
また，上記オーバーハング部材１を用いたオーバーハング部施工構造４においては，図１１に示すごとく，上記取付板３の水平板部３１２の上面に，下地材４２としての縦胴縁４２１の下端部４２３を当接させている。また，上記取付板３の上方脚板部３２は，上記縦胴縁４２１を介して構造躯体４１に固定してある。
なお，本例においては，横胴縁は配設していない。
その他は，実施例１と同様である。
この場合にも，実施例１と同様の作用効果を有する。
【００６０】
（実施例４）
本例は，図１２に示すごとく，面取本体２の前端面２１１の上下方向の幅を大きくしたオーバーハング部材１の例である。
上記前端面２１１の反対側には，該前端面２１１に略平行に形成した上部背面２２３が形成されている。この面取本体２の形状に合わせて，上記オーバーハング部材１における取付板３の固定板部３１が形成されている。
その他は，実施例１と同様である。
【００６１】
この場合には，上記オーバーハング部材１における面取本体２の上端面２２１の位置が，比較的高い位置に配される。従って，上記面取本体２とその上方に配される外壁板５との間に配設する目地処理材４７が，比較的高い位置に配される。
それ故，上記オーバーハング部を斜め下方から，即ち屋外から通常の視線角度で見上げたとき，上記目地処理材４７が目立ち難い。これにより，一層外観意匠性に優れたオーバーハング部施工構造４を得ることができる。
その他は，実施例１と同様の作用効果を有する。
【００６２】

BACKGROUND OF THE INVENTION
The present invention relates to an overhang member disposed at a front lower end portion of an overhang portion such as a veranda in a building.
[0002]
[Prior art]
Conventionally, as shown in FIG. 13, there is an overhang portion construction structure 8 of a hanging wall specification in which an outer wall plate 5 is disposed on a front wall surface of an overhang portion such as a veranda in a building.
The outer wall plate 5 is fixed to the structural housing 41 of the overhang portion through a base material 42 such as a longitudinal body edge and a ventilation spacer 46. In addition, an eaves top material 43 is disposed at the bottom of the overhang portion.
[0003]
However, when the overhanging portion construction structure 8 is viewed obliquely from the lower front, that is, from the outside at a normal viewing angle, the lower side portion 53 of the outer wall plate 5 is visible. Further, the outer wall design surface 51 of the outer wall plate 5 constituting the front wall surface of the overhang portion is suddenly interrupted at the lower end portion, which may deteriorate the appearance design.
[0004]
From this point of view, as shown in FIG. 14, there is an overhang portion construction structure 80 in which an overhang member 9 having an L-shaped longitudinal section is disposed at the front lower end portion of the overhang portion. Thereby, also in the front lower end part of the said overhang part, the design surface 95 similar to the outer wall design surface 51 of the said outer wall board 5 can be comprised, and the external appearance design property of the overhang part construction structure 80 is improved. Can do.
[0005]
The overhang member 9 is manufactured as follows, for example.
First, as shown in FIG. 15, a plate material 910 such as a ceramic-type outer wall plate is cut, and a plate piece 91 is cut into an appropriate size. Next, as shown in FIG. 16, one side end portion 911 of the plate piece 91 is cut obliquely to form a cut surface 914 that forms an angle of about 45 ° with respect to the front side surface 912 and the back side surface 913. Also, the end portion 916 of the front side surface 912 is chamfered to prevent chipping.
[0006]
Next, as shown in FIGS. 17 and 18, the cut surfaces 914 of the two plate pieces 91 are butted together and joined so that the front side surfaces 912 of the two plate pieces 91 are substantially perpendicular. At this time, an adhesive 92 is interposed between the cut surfaces 914 of the two plate pieces 91. Thereby, the two plate pieces 91 are bonded.
Further, a tacker 94 is driven into the joint portion 93 of the two plate pieces 91 to ensure the joint strength.
Next, as shown in FIG. 19, the outer corner portion 931 of the joint portion 93 is chamfered to prevent chipping of the outer corner portion 931 and improve the appearance design.
[0007]
[Problems to be solved by the invention]
However, as described above, the conventional overhang member 9 adheres the two plate pieces 91 using the adhesive 92. Therefore, it is necessary to cure the adhesive and it takes time to manufacture. In addition, a holding jig is required for drying in a state where the butting angle (for example, approximately 90 °) of the two plate pieces 91 is held.
