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】

【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。

【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。

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）

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an overhang member disposed at a lower front end 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 type 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 frame 41 of the overhang portion via a base material 42 such as a vertical trunk and a ventilation spacer 46. Further, an eave heaven material 43 is disposed at the bottom of the overhang portion.
[0003]
However, the lower side 53 of the outer wall plate 5 is visible when the overhang portion construction structure 8 is looked up from a diagonally lower front, that is, from the outside at a normal line-of-sight angle. Further, the outer wall design surface 51 of the outer wall plate 5 constituting the front wall surface of the overhang portion may be suddenly interrupted at the lower end, and the external design may be deteriorated.
[0004]
From this viewpoint, as shown in FIG. 14, there is an overhang portion construction structure 80 in which an overhang member 9 having an L-shaped vertical section is disposed at the lower front end of the overhang portion. Thus, a design surface 95 similar to the outer wall design surface 51 of the outer wall plate 5 can be formed at the lower front end of the overhang portion, and the external design of the overhang portion construction structure 80 can be improved. Can be.
[0005]
The overhang member 9 is manufactured, for example, as follows.
First, as shown in FIG. 15, a plate material 910 such as a ceramic outer wall plate is cut, and a plate piece 91 is cut out to an appropriate size. Next, as shown in FIG. 16, one side end 911 of the plate piece 91 is cut off obliquely to form a cut surface 914 that forms an angle of about 45 ° with the front side surface 912 and the back side surface 913. Also, the end 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 abutted to each other, and are joined so that the front side surfaces 912 of the two plate pieces 91 are substantially at right angles. At this time, the 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 tucker 94 is driven into the joint portion 93 of the two plate pieces 91 to secure the joint strength.
Next, as shown in FIG. 19, the outer corners 931 of the joints 93 are chamfered and cut to prevent chipping of the outer corners 931 and improve the appearance and design.
[0007]
[Problems to be solved by the invention]
However, the conventional overhang member 9 adheres the two pieces 91 using the adhesive 92 as described above. Therefore, adhesive curing is necessary, and it takes time to manufacture. In addition, a holding jig for drying the two plate pieces 91 while maintaining the butting angle (for example, approximately 90 °) is required.
[0008]
In addition, the adhesive 92 may protrude from the joint 93, which may degrade the appearance design of the overhang member 9. Therefore, in this case, it is necessary to scrape off the protruding adhesive 92 after the adhesive curing.
Further, as described above, it is necessary to strike the joining portion 93 with the tucker 94 or to chamfer the outer corner 931 of the joining portion 93. It is also necessary to repair the chamfered surface later.
[0009]
Further, when a pattern is formed on the front side surface 912 of the plate piece 91 and the pattern is shifted on both sides of the joint portion 93, a sense of incongruity is generated, and the appearance design of the overhang member 9 is deteriorated. There is a possibility that.
Therefore, when joining the two plate pieces 91, it is necessary to carefully perform alignment so that the pattern patterns do not shift from each other.
[0010]
Further, in the overhang portion construction structure, the front lower end is formed in a substantially right-angled shape, so that it is difficult to exhibit a gradual appearance, and in some cases, this may cause a reduction in the appearance design.
[0011]
The present invention has been made in view of such conventional problems, and has as its object to provide an overhang member which is easy to manufacture, is inexpensive, and has excellent appearance and design, and an overhang portion construction structure using the same.
