Description

【０００１】
【発明の属する技術分野】
本発明は、建物の出隅部の構造を主として意匠性向上の観点から改良した建物の出隅部構造に関するものである。
【０００２】
【従来の技術】
近年、住宅の外壁板として、表面柄模様の意匠性に優れ且つ施工性に優れたセメント系の外壁板の需要が著しく増大している。この外壁板を用いて施工された外壁の出隅部は、図１２に示すように、外壁板１１と同じ柄模様のＬ字形の出隅部材１２を使用し、この出隅部材１２を下地材１３を介して柱１４に釘１５等で固定するようにしている。
【０００３】
【発明が解決しようとする課題】
近年の消費者ニーズの多様化に伴って、建物の外観デザインも益々斬新性が求められる時代になってきている。また、１戸当たりの敷地面積が狭い日本特有の事情から建物の無駄な出っ張りを省いたコンパクトな構造の建物が求められている。しかし、上記従来の出隅部の構造では、出隅部のデザインに何ら新しさが無く、極めて単調なデザインである。しかも、狭い敷地では、出隅部の出っ張りが人の通行等の妨げになることがある。
【０００４】
本発明はこのような事情を考慮してなされたものであり、従ってその目的は、出隅部のデザインの斬新化とコンパクト化とを共に実現することができる建物の出隅部構造を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１の出隅部構造は、建物の出隅部に立設された柱の２つの側面にそれぞれ縦方向に延びる下地材を取り付けると共に、各側面の下地材に出隅部材を１つずつ宛がって取り付けることで、２つの出隅部材をＷ字形に連設して１つの出隅部を構成したところに１つの特徴がある。この構成では、出隅部がＷ字形構造となるため、出隅部がＶカット状に抉られた如き斬新なデザインになると共に、出隅部の出っ張りが従来より少なくなる。
【０００６】
この場合、請求項１のように、各出隅部材は、該出隅部材と同じ模様柄の小幅材を継ぎ足すことで、横幅を調整するようにすれば良い。このようにすれば、出隅部の下地材の厚み寸法が異なる建物に対しても同じ出隅部材を使用でき、出隅部材の共通化が可能となる。
【０００７】
更に、請求項１のように、前記２つの出隅部材の接合部分に形成される入隅部の裏側に、該入隅部の保持と防水を兼ねるバックアップ材を配設することが好ましい。このようにすれば、２つの出隅部材の接合部分（入隅部）の施工が容易になると共に、その入隅部から雨水が漏れても、その雨水の屋内側への浸入をバックアップ材で防ぐことができる。
【０００８】
また、請求項１のように、バックアップ材の入隅部に、２つの出隅部材の接合側の端面を受けるコーキング受台を設け、このコーキング受台と前記２つの出隅部材の接合側の端面とによって形成される隙間にコーキング材を充填するようにしても良い。このようにすれば、２つの出隅部材の接合部分（入隅部）の隙間へのコーキング材の充填状態が長期間安定して保たれ、コーキング材による防水効果が高まる。
【０００９】
また、請求項２のように、前記バックアップ材の入隅部に、前記２つの出隅部材の接合側の端面に挟み込まれる突片を設け、この突片の先端部に形成した係合片を左右に交互に折曲することで、各出隅部材の接合部分を係合保持するようにしても良い。このようにすれば、係合片の折曲という簡単な方法で各出隅部材の接合部分を保持することができる。
【００１０】
また、請求項３のように、前記２つの出隅部材の接合側の端面に、壁面と平行に延びる嵌合溝を形成し、前記バックアップ材の入隅部に突片が設けられており、この突片の先端部に形成した保持・防水兼用の二股リブを各出隅部材の端面の嵌合溝に嵌合するようにしても良い。このようにすれば、二股リブと嵌合溝とを嵌合するという極めて簡単な施工で、各出隅部材の接合部分の保持と防水とを行うことができ、コーキング材を充填しなくても、二股リブによって一次的な防水効果が得られる。
【００１１】
【発明の実施の形態】
［第１の実施形態］
以下、本発明を鉄骨構造建物に適用した第１の実施形態を図１乃至図４に基づいて説明する。図３に示すように、出隅部２０の内側には角パイプ柱２１が立設され、この角パイプ柱２１の屋外側の２つの側面には、下地材となるＣ型鋼２２が３本ずつ縦方向に沿って宛がわれ、溶接等により固着されている。これらのＣ型鋼２２には、外壁面を構成するセメント系の外壁板２３がビス２４によって取り付けられている。この外壁板２３の裏側には、予め防水シート２５がＣ型鋼２２に張り付けられている。
【００１２】
図１に示すように、角パイプ柱２１のコーナー部２１ａに固着された２つのＣ型鋼２２には、それぞれ小幅の出隅部材２６が１つずつ宛がわれ、ビス２７によって各Ｃ型鋼２２に取り付けられている。各出隅部材２６は、外壁板２３と同じ模様柄の２枚の短冊状板材の片端面をそれぞれ４５°程度の斜面にカットし、双方の斜面を接着剤により接着して製造したものである。各出隅部材２６と外壁板２３との接合部（目地）にはコーキング材２８が充填されている。
【００１３】
各出隅部材２６は、それぞれ出隅部材２６と同じ模様柄の小幅材２９を継ぎ足すことで、横幅がＣ型鋼２２の突出寸法に合わせて調整されている。各小幅材２９は、ビス３０によってＣ型鋼２２に取り付けられている。
【００１４】
図２に示すように、２枚の小幅材２９で形成される入隅部の裏側には、該入隅部の保持と防水を兼ねるバックアップ材３１が宛がわれ、ビス３２によってＣ型鋼２２に取り付けられている。このバックアップ材３１は、アルミ等の金属の押出し成形によりＬ字形に形成され（図４参照）、該バックアップ材３１の入隅部には、小幅材２９の端面を受けるコーキング受台３３が一体に形成され、このコーキング受台３３と小幅材２９の端面とによって形成される隙間にコーキング材３４が充填されている。
【００１５】
以上のように構成した出隅部２０によれば、角パイプ柱２１のコーナー部２１ａに固着された２つのＣ型鋼２２の間に形成されるＶカット状の隙間を利用し、２つの小幅の出隅部材２６をＷ字形に連設して１つの出隅部２０を構成するようにしたので、出隅部２０がＶカット状に抉られた如き斬新なデザインになり、意匠性が向上する。しかも、出隅部２０の出っ張りが従来より少なくなり、狭い敷地が多い日本の風土に合ったコンパクトな出隅部構造となる。
【００１６】
更に、各出隅部材２６は、該出隅部材２６と同じ模様柄の小幅材２９を継ぎ足すことで、横幅を調整するようにしたので、出隅部２０のＣ型鋼２２（下地材）の寸法が異なる建物に対しても同じ幅寸法の出隅部材２６を使用でき、出隅部材２６を共通化できて、その分、出隅部材２６の製造コストを低減できる利点がある。
【００１７】
但し、本発明は、小幅材２９を使用せず、下地材の寸法に合わせて形成した出隅部材２６のみを使用する構成としても良く、この場合には、施工性を向上できる利点がある。
【００１８】
また、上記実施形態では、２つの小幅材２９で形成される入隅部の裏側にバックアップ材３１を配設し、このバックアップ材３１のコーキング受台３３と小幅材２９の端面とによって形成される隙間にコーキング材３４を充填するようにしたので、２つの小幅材２９で形成される入隅部の防水構造は、コーキング材３４による一次的な防水と、バックアップ材３１による二次的な防水とからなる二重の防水構造となり、防水性能を向上することができる。しかも、バックアップ材３１を設けることで、２つの小幅材２９で作る入隅部の施工も容易になる。
【００１９】
［第２の実施形態］
以下、本発明を木造建物に適用した第２の実施形態を図５乃至図７に基づいて説明する。図５に示すように、出隅部５０の内側には、木材製の柱４１が立設され、この柱４１の屋外側の２つの側面には、下地材となる木材製の胴縁材４２が２本ずつ縦方向に沿って宛がわれ、釘（図示せず）等により取り付けられている。これらの胴縁材４２には、外壁面を構成するセメント系の外壁板４３が釘４４によって取り付けられている。この外壁板４３の裏側には、予め防水シート４５が胴縁材４２に張り付けられている。
【００２０】
柱４１のコーナー部４１ａに固定された２つの胴縁材４２には、それぞれ小幅の出隅部材４６が１つずつ宛がわれ、釘４７によって各胴縁材４２に取り付けられている。各出隅部材４６は、外壁板４３と同じ模様柄の２枚の短冊状の板材の片端面をそれぞれ４５°の斜面にカットし、双方の斜面を接着剤により接着して製造したものである。各出隅部材４６と外壁板４３との接合部（目地）にはコーキング材４８が充填されている。
【００２１】
この第２の実施形態では、第１の実施形態とは異なり、２つの出隅部材４６を小幅材を使用せずに直接継ぎ合わせてＷ字形の出隅部４０を構成し、２つの出隅部材４６の相対する端面をそれぞれ４５°程度の斜面にカットしている。２つの出隅部材４６で形成される入隅部の裏側には、該入隅部の保持と防水を兼ねるバックアップ材４９が宛がわれ、釘５０によって胴縁材４２に取り付けられている。このバックアップ材４９は、アルミ等の金属の押出し成形によりＬ字形に形成され（図７参照）、該バックアップ材４９の入隅部には突片５１が一体に形成され、この突片５１の先端部に複数の係合片５２が一体に形成されている。
【００２２】
バックアップ材４９の製造時には、各係合片５２は折曲されずに突片５１に真っ直ぐに形成され、施工時に２つの出隅部材４６をバックアップ材４９に宛がって両出隅部材４６の端面で突片５１を挟み込んだ状態で各係合片５２を左右に交互に折曲することで、両出隅部材４６の接合部分を係合保持する。この後、両出隅部材４６の接合部分にコーキング材５３を充填し、このコーキング材５３によって係合片５２を埋め込む。
【００２３】
以上説明した第２の実施形態でも、出隅部４０がＷ字形構造となるため、出隅部４０のデザインの斬新化とコンパクト化とを共に実現することができると共に、バックアップ材４９によって防水性・施工性を向上することができる。
【００２４】
［第３の実施形態］
以下、本発明を鉄骨構造建物に適用した第３の実施形態を図８乃至図１１に基づいて説明する。前述した第１の実施形態と同一部分には同一符号を付して説明を簡略化する。角パイプ柱２１の側面には、スペーサ６１を介してパネル固定板６２がボルト６３で固定されている。パネル固定板６２にはＣ型鋼６４が溶接等により固定され、このＣ型鋼６４の屋外側と屋内側に外壁板２３と内壁板６５が取り付けられている。角パイプ柱２１の屋外側の２つの側面には、下地材となるＣ型鋼２２が２本ずつ縦方向に沿って宛がわれ、溶接等により固着されている。
【００２５】
一方、バックアップ材６６は、出隅部６０全体をカバーするようにＷ字形に形成され、Ｃ型鋼２２に取り付けられている。そして、図１０に示すように、２つの出隅部材２６と各出隅部材２６の両側に継ぎ足した小幅材２９，６７をバックアップ材６６に宛がってビス３０，６８又は接着等の手段で取り付けることで、Ｗ字形構造の出隅部６０を構成している。
【００２６】
この第３の実施形態では、図１０に示すように、バックアップ材６６の入隅部に突片８０が設けられており、この突片８０の先端部には、保持・防水兼用の二股リブ６９が壁面と平行に延びるように一体に形成され、これに対応して、小幅材２９の接合側の端面には、嵌合溝７０が壁面と平行に延びるように形成されている。施工時に、二股リブ６９を小幅材２９の嵌合溝７０に嵌合することで、小幅材２９の接合部分の保持と防水とを同時に行う。この構造では、小幅材２９の接合部分にコーキング材を充填しなくても、二股リブ６９によって防水効果が得られ、その分、施工性を向上できる。
【００２７】
［その他の実施形態］
上記各実施形態では、施工時に２つの出隅部材２６，４６を別々に取り付けるようにしたが、予め２つの出隅部材をＷ字形に接着して一体化したものを工場生産するようにしても良い。また、凹凸模様のない壁面に本発明を適用する場合には、２つの出隅部材を押出し成形により一体に形成しても良い。
また、バックアップ材は、金属の押出し成形品に限定されず、金属板を折曲加工したもの、或はプラスチックの成形品を使用しても良い。
【００２８】
【発明の効果】
以上の説明から明らかなように、本発明の請求項１の出隅部構造によれば、出隅部内側の無駄な空間を少なくするようにＷ字形構造としたので、出隅部のデザインを斬新なものとすることができると共に、出隅部の出っ張りを少なくすることができて、狭い敷地が多い日本の風土に合ったコンパクトな出隅部構造とすることができる。
【００２９】
更に、請求項１では、出隅部材に同じ模様柄の小幅材を継ぎ足すことで、横幅を調整するようにしたので、種々の建物に同じ出隅部材を使用でき、出隅部材の共通化による低コスト化を期待できる。
【００３０】
また、請求項１では、２つの出隅部材の接合部分に形成される入隅部の裏側にバックアップ材を配設したので、施工性と防水性とを共に向上できる。
【００３１】
更に、請求項１では、バックアップ材の入隅部にコーキング受台を設けたので、コーキング材による防水効果を長期間にわたって安定的に維持できる。
【００３２】
また、請求項２では、バックアップ材の入隅部に設けた係合片を左右に交互に折曲することで、各出隅部材の接合部分を係合保持するようにしたので、各出隅部材の接合部分の保持を簡単且つ確実に行うことができる。
【００３３】
また、請求項３では、バックアップ材の入隅部に設けた二股リブと出隅部材の端面の嵌合溝とを嵌合するという極めて簡単な施工で、各出隅部材の接合部分の保持と防水とを行うことができ、コーキング材の充填が不要となり、施工性を向上できる。

Along with the diversification of consumer needs in recent years, the exterior design of buildings is becoming an era in which more innovativeness is required. In addition, there is a need for a building with a compact structure that eliminates wasteful protrusion of the building due to the unique circumstances of Japan where the site area per unit is small. However, in the conventional projecting corner structure, the design of the projecting corner has nothing new, and is a very monotonous design. Moreover, in a small site, the protrusion at the protruding corner may interfere with human traffic.
[0004]
The present invention has been made in view of such circumstances, and the object of the present invention is to provide a protruding corner structure of a building that can realize both a novel and compact design of the protruding corner. There is.

In this way, it is possible to hold and waterproof the joint portion of each protruding corner member with an extremely simple construction of fitting the bifurcated rib and the fitting groove, without having to fill the caulking material. The primary waterproof effect is obtained by the bifurcated rib.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
A first embodiment in which the present invention is applied to a steel structure building will be described below with reference to FIGS. As shown in FIG. 3, a square pipe column 21 is erected on the inner side of the protruding corner portion 20, and three C-shaped steels 22 serving as a base material are provided on two sides of the square pipe column 21 on the outdoor side. It is addressed along the vertical direction and fixed by welding or the like. A cement-type outer wall plate 23 constituting an outer wall surface is attached to these C-shaped steels 22 with screws 24. A waterproof sheet 25 is attached to the C-shaped steel 22 in advance on the back side of the outer wall plate 23.
[0012]
As shown in FIG. 1, each of the two C-shaped steels 22 fixed to the corner portion 21 a of the square pipe column 21 is assigned one small protruding corner member 26. It is attached. Each protruding corner member 26 is manufactured by cutting one end surface of two strip-shaped plate members having the same pattern as the outer wall plate 23 into a slope of about 45 °, and bonding both slopes with an adhesive. . A joint (joint) between each protruding corner member 26 and the outer wall plate 23 is filled with a caulking material 28.
[0013]
Each protruding corner member 26 is adjusted in accordance with the projecting dimension of the C-shaped steel 22 by adding a small width material 29 having the same pattern as the protruding corner member 26. Each narrow material 29 is attached to the C-shaped steel 22 with screws 30.
[0014]
As shown in FIG. 2, a back-up material 31 that serves as both retaining and waterproofing of the corner is assigned to the back side of the corner formed by the two narrow members 29, and the C-shaped steel 22 is attached to the C-shaped steel 22 by screws 32. It is attached. The backup material 31 is formed into an L shape by extrusion molding of a metal such as aluminum (see FIG. 4), and a coking cradle 33 for receiving the end face of the narrow material 29 is integrally formed at the corner of the backup material 31. The caulking material 34 is filled in a gap formed by the caulking cradle 33 and the end face of the narrow material 29.
[0015]
According to the projecting corner portion 20 configured as described above, two V-shaped gaps formed between the two C-shaped steels 22 fixed to the corner portion 21a of the square pipe column 21 are used. Since the protruding corner member 26 is connected in a W shape so as to form one protruding corner portion 20, the protruding corner portion 20 has a novel design such that it is bent in a V-cut shape, and the design is improved. . In addition, the protrusion of the protruding corner 20 is smaller than before, and a compact protruding corner structure suitable for the Japanese climate with many narrow sites is obtained.
[0016]
Furthermore, each protruding corner member 26 is adjusted by adding a small width material 29 having the same pattern as the protruding corner member 26, so that the width of the protruding corner member 26 of the C-shaped steel 22 (base material) of the protruding corner portion 20 is adjusted. The protruding corner member 26 having the same width can be used for buildings having different dimensions, and the protruding corner member 26 can be used in common, and the manufacturing cost of the protruding corner member 26 can be reduced accordingly.
[0017]
However, the present invention may be configured to use only the protruding corner member 26 formed in accordance with the dimensions of the base material without using the narrow material 29. In this case, there is an advantage that the workability can be improved.
[0018]
Further, in the above embodiment, the backup material 31 is disposed on the back side of the corner formed by the two narrow materials 29, and is formed by the caulking cradle 33 of the backup material 31 and the end surface of the narrow material 29. Since the caulking material 34 is filled in the gap, the waterproof structure of the corner portion formed by the two narrow materials 29 is the primary waterproofing by the caulking material 34 and the secondary waterproofing by the backup material 31. The waterproof structure can be improved because of the double waterproof structure. In addition, by providing the backup material 31, the construction of the corner portion made of the two narrow materials 29 is facilitated.
[0019]
[Second Embodiment]
Hereinafter, a second embodiment in which the present invention is applied to a wooden building will be described with reference to FIGS. As shown in FIG. 5, a wooden column 41 is erected on the inner side of the protruding corner portion 50, and a wooden trunk edge material 42 serving as a base material is provided on two outdoor side surfaces of the column 41. Are addressed along the vertical direction two by two and attached by nails (not shown) or the like. A cement-type outer wall plate 43 that constitutes the outer wall surface is attached to these trunk edge members 42 by nails 44. On the back side of the outer wall plate 43, a waterproof sheet 45 is pasted to the body edge material 42 in advance.
[0020]
A small projecting corner member 46 is addressed to each of the two body edge members 42 fixed to the corner portion 41 a of the column 41, and is attached to each body edge member 42 by a nail 47. Each protruding corner member 46 is manufactured by cutting one end surface of two strip-shaped plate members having the same pattern as the outer wall plate 43 into 45 ° inclined surfaces and bonding both inclined surfaces with an adhesive. . The joint (joint) between each protruding corner member 46 and the outer wall plate 43 is filled with a caulking material 48.
[0021]
In the second embodiment, unlike the first embodiment, two protruding corner members 46 are directly joined together without using a narrow material to form a W-shaped protruding corner portion 40, thereby forming two protruding corners. The opposing end surfaces of the member 46 are cut into inclined surfaces of about 45 °. A back-up material 49 that serves as both retaining and waterproofing of the corner is assigned to the back side of the corner formed by the two projecting corner members 46, and is attached to the trunk edge member 42 by a nail 50. The backup material 49 is formed in an L shape by extrusion molding of a metal such as aluminum (see FIG. 7), and a protruding piece 51 is integrally formed at the corner of the backup material 49. The tip of the protruding piece 51 A plurality of engaging pieces 52 are integrally formed in the portion.
[0022]
At the time of manufacturing the backup material 49, each engagement piece 52 is not bent but is formed straight on the protruding piece 51, and at the time of construction, the two protruding corner members 46 are directed to the backup material 49, and the two protruding corner members 46 are formed. By bending the engaging pieces 52 alternately left and right with the projecting pieces 51 sandwiched between the end faces, the joint portions of the protruding corner members 46 are engaged and held. Thereafter, the caulking material 53 is filled in the joint portion of both protruding corner members 46, and the engagement piece 52 is embedded by the caulking material 53.
[0023]
Also in the second embodiment described above, since the protruding corner portion 40 has a W-shaped structure, it is possible to realize both a novel design and a compact size of the protruding corner portion 40, and a waterproof property by the backup material 49. -The workability can be improved.
[0024]
[Third Embodiment]
A third embodiment in which the present invention is applied to a steel structure building will be described below with reference to FIGS. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description will be simplified. A panel fixing plate 62 is fixed to the side surface of the square pipe column 21 with a bolt 63 via a spacer 61. A C-shaped steel 64 is fixed to the panel fixing plate 62 by welding or the like, and an outer wall plate 23 and an inner wall plate 65 are attached to the outdoor side and the indoor side of the C-shaped steel 64. Two C-shaped steels 22 serving as base materials are addressed to the two side surfaces of the square pipe column 21 on the outdoor side along the vertical direction, and are fixed by welding or the like.
