壁下地5は、複数の柱50、複数の下地板53及び複数の胴縁54を有している。複数の柱50は、隅柱である柱500を含んでいる。柱500は、直角に隣接した二つの外面(屋外側の面)501,502を有している。 The wall base 5 has a number of columns 50, a number of base boards 53, and a number of furring strips 54. The number of columns 50 includes a column 500 which is a corner column. The column 500 has two outer surfaces (surfaces facing the outside) 501, 502 adjacent to each other at a right angle.

複数の下地板53の各々は、例えば、単数又は複数の合板である。複数の下地板53は、例えば、釘又はねじ等の固着具によって複数の柱50に取り付けられる。複数の下地板53は、柱500に取り付けられた2枚の下地板531,532を含んでいる。2枚の下地板531,532は、それぞれ柱500の二つの外面501,502に沿って配置されている。 Each of the multiple base plates 53 is, for example, a single piece or pieces of plywood. The multiple base plates 53 are attached to the multiple columns 50 by fasteners such as nails or screws. The multiple base plates 53 include two base plates 531, 532 attached to the column 500. The two base plates 531, 532 are arranged along the two outer surfaces 501, 502 of the column 500, respectively.

複数の下地板53には、複数の胴縁54が取り付けられている。各胴縁54は、下地板53の外面に沿って上下方向に延びた縦胴縁である。各胴縁54は、例えば、釘又はねじ等の固着具によって下地板53に取り付けられる。なお、各下地板53の外面には、透湿防水シートが張り付けられてもよい。この場合、各胴縁54は、透湿防水シートを介して下地板53に取り付けられる。 A number of furring strips 54 are attached to the multiple base boards 53. Each furring strip 54 is a vertical furring strip that extends vertically along the outer surface of the base board 53. Each furring strip 54 is attached to the base board 53 by fasteners such as nails or screws. A moisture-permeable waterproof sheet may be attached to the outer surface of each base board 53. In this case, each furring strip 54 is attached to the base board 53 via the moisture-permeable waterproof sheet.

複数の胴縁54は、壁下地5の出隅部に設けられた二つの胴縁541,542を含んでいる。二つの胴縁541,542のうちの一方の胴縁541は、一方の下地板531の外面における出隅側(他方の下地板532側)の端部に取り付けられており、他方の胴縁542は、他方の下地板532の外面における出隅側(一方の下地板531側)の端部に取り付けられている。 The multiple furring strips 54 include two furring strips 541, 542 provided at the protruding corners of the wall base 5. Of the two furring strips 541, 542, one furring strip 541 is attached to the end of the protruding corner side (the other base board 532 side) on the outer surface of one base board 531, and the other furring strip 542 is attached to the end of the protruding corner side (the one base board 531 side) on the outer surface of the other base board 532.

壁下地5は、出隅部において隣り合う二つの外面51,52を有している。二つの外面51,52は、互いに垂直である。二つの外面51,52は、それぞれ二つの胴縁541,542の外面で構成されている。 The wall base 5 has two adjacent outer surfaces 51, 52 at the protruding corner. The two outer surfaces 51, 52 are perpendicular to each other. The two outer surfaces 51, 52 are each composed of the outer surfaces of two furring strips 541, 542.

なお、壁下地5の各外面51,52は、胴縁54の外面で構成されたものに限定されない。例えば、壁下地5の各外面51,52は、下地板53の外面であってもよい。また、壁下地5の二つの外面51,52がなす角度は、直角に限定されず、鈍角であってもよいし、鋭角であってもよい。すなわち、出隅構造1の二つの壁材61,62がなす角度は、直角に限定されず、鈍角であってもよいし、鋭角であってもよい。また、壁下地5は、既設の外壁であってもよい。この場合、各壁材6はリフォーム用の壁材として用いられ、各壁材6及び出隅部材2は、既設の外壁に取り付けられる。 The outer surfaces 51, 52 of the wall base 5 are not limited to being formed by the outer surfaces of the furring strips 54.

The angle between the two outer surfaces 51, 52 of the wall base 5 is not limited to a right angle, but may be an obtuse angle or an acute angle. In other words, the angle between the two wall materials 61, 62 of the corner structure 1 is not limited to a right angle, but may be an obtuse angle or an acute angle. The wall base 5 may be an existing exterior wall. In this case, each wall material 6 is used as a wall material for renovation, and each wall material 6 and the corner member 2 are attached to the existing exterior wall.

壁下地5には、外壁の出隅役物として、図2に示す出隅部材2が取り付けられている。出隅部材2は、壁下地5の二つの外面51,52に沿って上下方向に延びた長尺部材である。出隅部材2の上下長さは、例えば、3030mmである。なお、出隅部材2の上下長さは、限定されない。 The corner member 2 shown in FIG. 2 is attached to the wall base 5 as a corner accessory for the exterior wall. The corner member 2 is a long member that extends in the vertical direction along the two outer surfaces 51, 52 of the wall base 5. The vertical length of the corner member 2 is, for example, 3030 mm. However, the vertical length of the corner member 2 is not limited.

出隅部材2は、一続きの単一部材であり、一部材だけで構成されている。出隅部材2は、板金製であり、一枚の金属板を曲げ加工して形成されている。なお、出隅部材2は、複数の部材の組み合わせであってもよく、一部材で構成されなくてもよい。 The corner member 2 is a continuous single member and is composed of only one member. The corner member 2 is made of sheet metal and is formed by bending a single metal plate.

他方壁材側収容部42の底部420は、側壁部421において出隅とは反対側の端部(他方接続部44に接続された端部とは反対側の端部)から側壁部421の内面側(他方接続部44とは反対側)に向かって突出している。底部420は、一方壁材側収容部41の側壁部411と平行な平板状に形成されている。底部420は、一方壁材側収容部41の側壁部411と間隔をあけて位置しており、底部420と一方壁材側収容部41の側壁部411との間には、隙間が形成されている。底部420において側壁部411に接続された端部とは反対側の端部は、自由端である。ただし、底部420の側壁部411に接続された端部とは反対側の端部の側壁部411側には、底部420を構成する板状部分を折り返して形成された折返部422が形成されている。折返部422は、例えば、底部420を構成する板状部分をヘミング加工することにより形成される。 The bottom 420 of the other wall material side storage section 42 protrudes from the end of the side wall section 421 opposite the corner (the end opposite the end connected to the other connection section 44) toward the inner surface side of the side wall section 421 (the side opposite the other connection section 44). The bottom 420 is formed in a flat plate shape parallel to the side wall section 411 of the one wall material side storage section 41. The bottom 420 is located at a distance from the side wall section 411 of the one wall material side storage section 41, and a gap is formed between the bottom 420 and the side wall section 411 of the one wall material side storage section 41. The end of the bottom 420 opposite the end connected to the side wall section 411 is a free end. However, a folded portion 422 formed by folding back the plate-shaped portion constituting the bottom 420 is formed on the side wall section 411 side of the end opposite the end connected to the side wall section 411 of the bottom 420. The folded portion 422 is formed, for example, by hemming the plate-shaped portion that constitutes the bottom portion 420.

出隅構造1は、二つのバックアップ材81,82を備えている。各バックアップ材81,82は、例えば、樹脂又はゴム等から形成される。二つのバックアップ材81,82のうちの一方のバックアップ材81は、一方目地材71をバックアップし、他方のバックアップ材82は他方目地材72をバックアップする。以下、バックアップ材81を一方バックアップ材81といい、バックアップ材82を他方バックアップ材82という。 The corner structure 1 includes two backup materials 81, 82. Each backup material 81, 82 is formed, for example, from resin or rubber. Of the two backup materials 81, 82, one backup material 81 backs up one joint material 71, and the other backup material 82 backs up the other joint material 72. Hereinafter, the backup material 81 will be referred to as the one backup material 81, and the backup material 82 will be referred to as the other backup material 82.

一方バックアップ材81は、出隅部材2の一方壁材側収容部41の底部410の外面に沿って上下方向に延びており、出隅部材2に取り付けられている。他方バックアップ材82は、出隅部材2の他方壁材側収容部42の底部420の外面に沿って上下方向に延びており、出隅部材2に取り付けられている。一方バックアップ材81及び他方バックアップ材82の各々は、例えば、接着剤、粘着剤又は両面テープ等によって出隅部材2に取り付けられる。なお、本実施形態の各バックアップ材81,82は、出隅部材2の出荷前に取り付けられるが、出荷後の出隅部材2に取り付けられてもよい。 The one-side backup material 81 extends vertically along the outer surface of the bottom 410 of the one-wall material side storage portion 41 of the protruding corner member 2, and is attached to the protruding corner member 2. The other-side backup material 82 extends vertically along the outer surface of the bottom 420 of the other-wall material side storage portion 42 of the protruding corner member 2, and is attached to the protruding corner member 2. Each of the one-side backup material 81 and the other-side backup material 82 is attached to the protruding corner member 2, for example, by adhesive, pressure-sensitive adhesive, double-sided tape, or the like. Note that, although the respective backup materials 81, 82 in this embodiment are attached before the protruding corner member 2 is shipped, they may also be attached to the protruding corner member 2 after shipment.

複数の壁材6の各々は、例えば、窯業系パネル、木製パネル、ALC(Autoclaved Lightweight aerated Concrete)パネル又は金属系サイディング等である。各壁材6は、矩形板状に形成されている。複数の壁材6のうちの一つである一方壁材61は、裏面(内面)が出隅部材2の一方固定片31の外面に沿い、かつ、出隅側の端面が、出隅部材2の一方壁材側収容部41の底部410(詳しくは、底部410と一方接続部43との接続部分)に接した状態で、壁下地5に取り付けられている。一方壁材61は、例えば、釘又はビス等の固着具によって複数の胴縁54に固定されることで、壁下地5に取り付けられる。一方壁材61の表面(外面)は、一方壁材61の厚み方向において、出隅部材2の他方接続部44の外面(側壁部421とは反対側の面)と同位置に位置している。 Each of the multiple wall materials 6 is, for example, a ceramic panel, a wood panel, an ALC (Autoclaved Lightweight Aerated Concrete) panel, or a metal siding. Each wall material 6 is formed in a rectangular plate shape. One of the multiple wall materials 6, a first wall material 61, is attached to the wall base 5 with its back surface (inner surface) along the outer surface of the first fixing piece 31 of the corner member 2 and its end surface on the corner side in contact with the bottom 410 (more specifically, the connection portion between the bottom 410 and the first connection portion 43) of the first wall material side accommodation portion 41 of the corner member 2. The first wall material 61 is attached to the wall base 5 by being fixed to the multiple furring strips 54 with fasteners such as nails or screws. The surface (outer surface) of the first wall material 61 is located at the same position as the outer surface (the surface opposite to the side wall portion 421) of the second connection portion 44 of the corner member 2 in the thickness direction of the first wall material 61.

複数の壁材6のうちの一つである他方壁材62は、裏面(内面)が出隅部材2の他方固定片32の外面に沿い、かつ、出隅側の端面が、出隅部材2の他方壁材側収容部42の底部420(詳しくは、底部420における側壁部421が接続された端部とは反対側の端部)に接した状態で、壁下地5に取り付けられている。他方壁材62は、例えば、釘又はビス等の固着具によって複数の胴縁54に固定されることで、壁下地5に取り付けられる。他方壁材62の表面(外面)は、他方壁材62の厚み方向において、出隅部材2の曲部45の外面と略同位置に位置している。 The other wall material 62, which is one of the multiple wall materials 6, is attached to the wall base 5 with its back surface (inner surface) aligned along the outer surface of the other fixed piece 32 of the corner member 2 and with its end surface on the corner side in contact with the bottom 420 of the other wall material side accommodation section 42 of the corner member 2 (more specifically, the end of the bottom 420 opposite to the end to which the side wall section 421 is connected). The other wall material 62 is attached to the wall base 5 by being fixed to the multiple furring strips 54 with fasteners such as nails or screws. The surface (outer surface) of the other wall material 62 is located at approximately the same position as the outer surface of the curved section 45 of the corner member 2 in the thickness direction of the other wall material 62.

一方壁材61における出隅側の端面は、出隅部材2の一方壁材側収容部41の側壁部411と、幅方向に間隔をあけて位置している。一方壁材61における出隅側の端面と、出隅部材2の側壁部411との間には、上下方向に延びた目地91が形成されている。目地91には、一方目地材71が配置されている。 The end face of the wall material 61 on the protruding corner side is positioned with a gap in the width direction from the side wall portion 411 of the one-wall material side storage portion 41 of the protruding corner member 2. A joint 91 extending in the vertical direction is formed between the end face of the wall material 61 on the protruding corner side and the side wall portion 411 of the protruding corner member 2. A one-side joint material 71 is arranged in the joint 91.

一方目地材71は、湿式の目地材であり、詳しくはシーリング材である。一方目地材71は、出隅部材2の一方壁材側収容部41(底部410及び側壁部411)と、一方壁材61における出隅側の端面と、一方バックアップ材81とで囲まれた空間に充填されている。一方壁材側収容部41の底部410は、一方バックアップ材81の裏側(屋内側)、かつ、一方目地材71の裏側に位置している。一方目地材71は、目地91から、屋内側に水が浸入することを抑制する。なお、一方目地材71は、乾式の目地材であってもよい。 The one-sided joint material 71 is a wet joint material, specifically a sealing material. The one-sided joint material 71 is filled in the space surrounded by the one-sided wall material storage portion 41 (bottom portion 410 and side wall portion 411) of the corner member 2, the end face of the corner side of the one-sided wall material 61, and the one-sided back-up material 81. The bottom portion 410 of the one-sided wall material storage portion 41 is located on the back side (indoor side) of the one-sided back-up material 81 and on the back side of the one-sided joint material 71. The one-sided joint material 71 prevents water from entering the indoor side through the joint 91. The one-sided joint material 71 may be a dry joint material.

他方壁材62における出隅側の端面は、出隅部材2の他方壁材側収容部42の側壁部421と、幅方向に間隔をあけて位置している。他方壁材62における出隅側の端面と、出隅部材2の側壁部421との間には、上下方向に延びた目地92が形成されている。目地92には、他方目地材72が配置されている。 The end face of the other wall material 62 on the protruding corner side is positioned with a gap in the width direction from the side wall portion 421 of the other wall material side storage portion 42 of the protruding corner member 2. A joint 92 extending in the vertical direction is formed between the end face of the other wall material 62 on the protruding corner side and the side wall portion 421 of the protruding corner member 2. The other joint material 72 is arranged in the joint 92.

他方目地材72は、湿式の目地材であり、詳しくはシーリング材である。他方目地材72は、出隅部材2の他方壁材側収容部42(底部420及び側壁部421)と、他方壁材62における出隅側の端面と、他方バックアップ材82とで囲まれた空間に充填されている。他方目地材72は、目地92から屋内側に水が浸入することを抑制する。なお、一方目地材71及び他方目地材72の各々は、乾式の目地材であってもよい。他方壁材側収容部42の底部420は、他方バックアップ材82の裏側(屋内側)、かつ、他方目地材72の裏側に位置している。 The other joint material 72 is a wet joint material, specifically a sealing material. The other joint material 72 is filled in the space surrounded by the other wall material side storage portion 42 (bottom portion 420 and side wall portion 421) of the corner member 2, the end face of the corner side of the other wall material 62, and the other back-up material 82. The other joint material 72 prevents water from entering the interior side through the joint 92. Note that each of the one joint material 71 and the other joint material 72 may be a dry joint material. The bottom portion 420 of the other wall material side storage portion 42 is located on the back side (indoor side) of the other back-up material 82 and on the back side of the other joint material 72.

出隅部材2の突出部4は、一方壁材61の表面側に露出した幅広部46と、他方壁材62の表面側に露出した幅狭部47とを有している。本実施形態において、幅広部46は他方接続部44であり、幅狭部47は曲部45である。 The protruding portion 4 of the corner member 2 has a wide portion 46 exposed on the surface side of the one wall material 61 and a narrow portion 47 exposed on the surface side of the other wall material 62. In this embodiment, the wide portion 46 is the other connection portion 44, and the narrow portion 47 is the curved portion 45.

幅広部46は突出部4において一方目地材71の出隅側に位置し、出隅部材2において幅広部46よりも一方壁材61側に位置する部分は、一方壁材61及び一方目地材71によって屋外側が覆われている。出隅部材2及び突出部4の各々は、幅広部46だけが一方壁材61の表面側に露出している。 The wide portion 46 is located on the protruding portion 4's protruding corner side of the one joint material 71, and the portion of the protruding corner member 2 that is located on the one wall material 61 side of the wide portion 46 is covered on the outdoor side by the one wall material 61 and the one joint material 71. For each of the protruding corner member 2 and the protruding portion 4, only the wide portion 46 is exposed on the surface side of the one wall material 61.

幅狭部47は突出部4において他方目地材72の出隅側に位置し、出隅部材2において幅狭部47よりも他方壁材62側に位置する部分は、他方壁材62及び他方目地材72によって屋外側が覆われる。出隅部材2及び突出部4の各々は、幅狭部47だけが他方壁材62の表面側に露出している。 The narrow portion 47 is located on the protruding portion 4's protruding corner side of the other joint material 72, and the portion of the protruding corner member 2 that is located on the other wall material 62 side of the narrow portion 47 is covered on the outdoor side by the other wall material 62 and the other joint material 72. For each of the protruding corner member 2 and the protruding portion 4, only the narrow portion 47 is exposed on the surface side of the other wall material 62.

幅広部46(他方接続部44)は、一方壁材61の表面側から見て、上下方向に延びた矩形の面状をなしている。幅広部46の幅は、幅広部46の上下方向の全長に亘って一定である。幅狭部47(曲部45)は、他方壁材62の表面側から見て上下方向に延びた線状をなしている。幅狭部47の幅は、幅狭部47の上下方向の全長に亘って一定である。幅狭部47の幅は、幅広部46(一方接続部43)の幅よりも小さい。このため、出隅構造1を他方壁材62の表面側から見たときには、出隅部材2の露出する部分(幅狭部47)の面積が小さく、出隅部材2は目立ち難い。殊に、一方壁材61の表面が、隣接する建物に臨む場合又は建物に隣接する駐車場側に臨む場合等、他方壁材62の表面と比べて外観上見られる機会が少ない場合、出隅構造1の外観は、非常にシンプルで優れた外観となる。 The wide portion 46 (the other connection portion 44) has a rectangular surface extending in the vertical direction when viewed from the surface side of the one wall material 61. The width of the wide portion 46 is constant over the entire vertical length of the wide portion 46. The narrow portion 47 (curved portion 45) has a linear shape extending in the vertical direction when viewed from the surface side of the other wall material 62. The width of the narrow portion 47 is constant over the entire vertical length of the narrow portion 47. The width of the narrow portion 47 is smaller than the width of the wide portion 46 (the one connection portion 43). Therefore, when the corner structure 1 is viewed from the surface side of the other wall material 62, the area of the exposed portion (narrow portion 47) of the corner member 2 is small, and the corner member 2 is not easily noticeable. In particular, when the surface of one wall material 61 faces an adjacent building or faces a parking lot adjacent to a building, and is less likely to be seen than the surface of the other wall material 62, the exterior appearance of the corner structure 1 is very simple and excellent.

出隅構造1の施工は、例えば、以下に示すように行われる。まず、出隅部材2が壁下地5に取り付けられる。次に、一方壁材61及び他方壁材62が壁下地5に取り付けられる。この後、一方壁材61と出隅部材2との間と、他方壁材62と出隅部材2との間とに、一方目地材71及び他方目地材72がそれぞれ充填される。これにより、出隅構造1の施工が完了する。本実施形態の出隅部材2は、一部材で構成されているため、施工が容易である。 The construction of the protruding corner structure 1 is performed, for example, as shown below. First, the protruding corner member 2 is attached to the wall base 5. Next, the first wall material 61 and the second wall material 62 are attached to the wall base 5. After this, the first joint material 71 and the second joint material 72 are filled between the first wall material 61 and the protruding corner member 2, and between the second wall material 62 and the protruding corner member 2, respectively. This completes the construction of the protruding corner structure 1. The protruding corner member 2 of this embodiment is constructed from a single member, making it easy to construct.

出隅部材2の一方壁材側収容部41及び他方壁材側収容部42の各々は、壁材61,62の位置決めに利用し得る壁材位置決部413,423を有している。一方壁材側収容部41の壁材位置決部413は、一方壁材61の移動を規制する一方壁材用位置決部であり、他方壁材側収容部42の壁材位置決部423は、他方壁材62の移動を規制する他方壁材用位置決部である。本実施形態において、一方壁材用位置決部413は一方壁材側収容部41の底部410であり、他方壁材用位置決部423は他方壁材側収容部42の底部420である。 The one-wall-material-side accommodation section 41 and the other-wall-material-side accommodation section 42 of the corner member 2 each have a wall material positioning section 413, 423 that can be used to position the wall materials 61, 62. The wall material positioning section 413 of the one-wall-material-side accommodation section 41 is a one-wall-material positioning section that restricts the movement of the one-wall material 61, and the wall material positioning section 423 of the other-wall-material-side accommodation section 42 is a other-wall-material positioning section that restricts the movement of the other-wall material 62. In this embodiment, the one-wall-material positioning section 413 is the bottom 410 of the one-wall-material-side accommodation section 41, and the other-wall-material positioning section 423 is the bottom 420 of the other-wall-material-side accommodation section 42.

一方壁材61を壁下地5に取り付ける際には、一方壁材61の裏面が出隅部材2の一方固定片31の外面に沿った状態で、一方壁材61の出隅側の端面を出隅部材2の一方壁材用位置決部413(詳しくは、底部410において側壁部411が接続された端部とは反対側の端部)に接触させる。これにより、一方壁材61の幅広部46(他方接続部44)側への移動を規制することができ、この状態で一方壁材61を壁下地5に取り付けることで、一方壁材61を所定位置に配置できる。 When attaching the one-side wall material 61 to the wall base 5, the back surface of the one-side wall material 61 is aligned with the outer surface of the one-side fixing piece 31 of the projecting corner member 2, and the end surface of the projecting corner side of the one-side wall material 61 is brought into contact with the one-side wall material positioning portion 413 of the projecting corner member 2 (more specifically, the end portion opposite the end portion to which the side wall portion 411 is connected at the bottom portion 410). This makes it possible to restrict movement of the one-side wall material 61 toward the wide portion 46 (the other-side connection portion 44), and by attaching the one-side wall material 61 to the wall base 5 in this state, the one-side wall material 61 can be positioned in a predetermined position.

他方壁材62を壁下地5に取り付ける際には、他方壁材62の裏面が出隅部材2の他方固定片32の外面に沿った状態で、他方壁材62の出隅側の端面を出隅部材2の他方壁材用位置決部423(詳しくは、底部420において側壁部421が接続された端部とは反対側の端部)に接触させる。これにより、他方壁材62の幅狭部47(曲部45)側への移動を規制することができ、この状態で他方壁材62を壁下地5に取り付けることで、他方壁材62を所定位置に配置できる。したがって、各壁材61,62を水平方向における所定位置に容易に施工することが可能になる。また、一方壁材61と幅広部46との間に形成される目地91の幅及び他方壁材62と幅狭部47との間に形成される目地92の幅の各々を一定にすることができ、出隅構造1の外観を一層向上できる。 When attaching the other wall material 62 to the wall base 5, the end surface of the other wall material 62 on the protruding corner side is brought into contact with the other wall material positioning portion 423 of the protruding corner member 2 (more specifically, the end portion opposite to the end portion to which the side wall portion 421 is connected at the bottom portion 420) with the back surface of the other wall material 62 aligned with the outer surface of the other fixed piece 32 of the protruding corner member 2. This makes it possible to restrict the movement of the other wall material 62 toward the narrow portion 47 (curved portion 45), and by attaching the other wall material 62 to the wall base 5 in this state, the other wall material 62 can be positioned in a predetermined position. Therefore, it is possible to easily install each wall material 61, 62 in a predetermined position in the horizontal direction. In addition, the width of the joint 91 formed between the one wall material 61 and the wide portion 46 and the width of the joint 92 formed between the other wall material 62 and the narrow portion 47 can each be made constant, further improving the appearance of the protruding corner structure 1.

(2)変形例
次に上記実施形態の変形例について説明する。なお、以下の変形例の説明では、上記実施形態と共通する事項については説明を省略する。
(2) Modifications Next, modifications of the above embodiment will be described. In the following description of the modifications, the description of matters common to the above embodiment will be omitted.

(2-1)変形例1
図3に示す変形例1の出隅構造1は、出隅部材2の他方壁材側収容部42の形状が、実施形態と異なる。本変形例の出隅部材2は、他方壁材側収容部42の底部420が、一方壁材側収容部41の側壁部411に接している。底部420において側壁部421に接続された端部とは反対側の端部には、折返部422(図1参照)が形成されておらず、底部420は重なり部分の無い一枚板状に形成されている。他方壁材側収容部42の底部420が、一方壁材側収容部41の側壁部411に支持されることで、一方壁材側収容部41の変形が抑制される。
(2-1) Modification 1
In the projected corner structure 1 of the modified example 1 shown in Fig. 3, the shape of the other-wall material side accommodation portion 42 of the projected corner member 2 is different from that of the embodiment. In the projected corner member 2 of this modified example, the bottom 420 of the other-wall material side accommodation portion 42 is in contact with the side wall portion 411 of the one-wall material side accommodation portion 41. At the end of the bottom 420 opposite to the end connected to the side wall portion 421, the folded portion 422 (see Fig. 1) is not formed, and the bottom 420 is formed in a single plate shape without overlapping portions. The bottom 420 of the other-wall material side accommodation portion 42 is supported by the side wall portion 411 of the one-wall material side accommodation portion 41, thereby suppressing deformation of the one-wall material side accommodation portion 41.

(2-2)変形例2
図4に示す変形例2の出隅構造1は、出隅部材2の突出部4の形状が、実施形態と異なる。本変形例の突出部4は、他方壁材側収容部42の底部420が一方壁材側収容部41の側壁部411を兼ねている。突出部4は、他方接続部44(図1参照)を有していない。
(2-2) Modification 2
The corner structure 1 of the second modified example shown in Fig. 4 differs from the embodiment in the shape of the protruding portion 4 of the corner member 2. In the protruding portion 4 of this modified example, the bottom portion 420 of the other-wall material side accommodation portion 42 also serves as the side wall portion 411 of the one-wall material side accommodation portion 41. The protruding portion 4 does not have the other connection portion 44 (see Fig. 1).

固定部3から一方固定片31の外面側に突出した一方接続部43は、一方固定片31に対して垂直で他方固定片32と平行な平板状に形成されている。他方壁材側収容部42の側壁部421は、一方壁材側収容部41の側壁部411を兼ねる底部420に連続している。側壁部421は、底部420において一方側壁材側収容部41の底部410が接続された端部とは反対側の端部から出隅側に向かって突出している。他方壁材側収容部42の側壁部421は、一方固定片31と平行な平板状に形成されている。 The one-side connection portion 43 protruding from the fixing portion 3 to the outer surface side of the one-side fixing piece 31 is formed in a flat plate shape perpendicular to the one-side fixing piece 31 and parallel to the other-side fixing piece 32. The side wall portion 421 of the other-side wall material side storage portion 42 is continuous with the bottom portion 420 which also serves as the side wall portion 411 of the one-side wall material side storage portion 41. The side wall portion 421 protrudes toward the corner side from the end of the bottom portion 420 opposite the end to which the bottom portion 410 of the one-side wall material side storage portion 41 is connected. The side wall portion 421 of the other-side wall material side storage portion 42 is formed in a flat plate shape parallel to the one-side fixing piece 31.

側壁部421における出隅側の端部は、自由端である。ただし、側壁部421における出隅側の端部の内面側には、側壁部421を構成する板状部分を折り返して形成された折返部422が形成されている。折返部422は、例えば、側壁部421を構成する板状部分をヘミング加工することにより形成される。 The end of the side wall 421 on the protruding corner side is a free end. However, a folded portion 422 is formed by folding back the plate-shaped portion that constitutes the side wall 421 on the inner surface of the end of the side wall 421 on the protruding corner side. The folded portion 422 is formed, for example, by hemming the plate-shaped portion that constitutes the side wall 421.

本変形例の出隅構造1は、バックアップ材81,82(図1参照)を備えていない。なお、出隅構造1は、上記実施形態と同様に、各目地材71,72をバックアップするバックアップ材81,82を備えてもよい。 The corner structure 1 of this modified example does not include backup materials 81, 82 (see FIG. 1). Note that the corner structure 1 may include backup materials 81, 82 that back up the joint materials 71, 72, as in the above embodiment.

一方壁材61は、出隅側の端面が、出隅部材2の一方接続部43に接した状態で、壁下地5に取り付けられている。本変形例の一方壁材用位置決部413は、一方接続部43である。一方壁材61の表面は、一方壁材61の厚み方向において、出隅部材2の他方壁材側収容部42の側壁部421の外面と同位置に位置している。 The one-wall material 61 is attached to the wall base 5 with the end face on the protruding corner side in contact with the one-side connection portion 43 of the protruding corner member 2. The one-wall material positioning portion 413 of this modified example is the one-side connection portion 43. The surface of the one-wall material 61 is located at the same position in the thickness direction of the one-wall material 61 as the outer surface of the side wall portion 421 of the other-wall material side accommodation portion 42 of the protruding corner member 2.

他方壁材62は、出隅側の端面が、出隅部材2の一方壁材側収容部41の底部410に接した状態で壁下地5に取り付けられている。本変形例の他方壁材用位置決部423は、一方壁材側収容部41の底部410である。他方壁材62の表面は、他方壁材62の厚み方向において、出隅部材2の一方壁材側収容部41の側壁部411における出隅側の端部と同位置に位置している。 The other wall material 62 is attached to the wall base 5 with the end face on the protruding corner side in contact with the bottom 410 of the one-wall material side storage section 41 of the protruding corner member 2. The other wall material positioning section 423 of this modified example is the bottom 410 of the one-wall material side storage section 41. The surface of the other wall material 62 is located in the same position in the thickness direction of the other wall material 62 as the end of the protruding corner side of the side wall section 411 of the one-wall material side storage section 41 of the protruding corner member 2.

一方目地材71は、一方壁材61の出隅側の端面と出隅部材2の側壁部411との間に形成された目地91の全体に充填されている。他方目地材72は、他方壁材62の出隅側の端面と出隅部材2の側壁部421との間に形成された目地92の全体に充填されている。 The first joint material 71 fills the entire joint 91 formed between the end face of the protruding corner of the first wall material 61 and the side wall portion 411 of the protruding corner member 2. The second joint material 72 fills the entire joint 92 formed between the end face of the protruding corner of the second wall material 62 and the side wall portion 421 of the protruding corner member 2.

本変形例では、出隅部材2の幅広部46が、他方壁材側収容部42の側壁部421であり、幅狭部47が側壁部421において側壁部411が接続された端部とは反対側の端部である。幅狭部47は、ヘミング加工により形成された側壁部421の端部であって幅が非常に小さいため、一層目立ち難い。 In this modified example, the wide portion 46 of the corner member 2 is the side wall portion 421 of the other wall material side storage portion 42, and the narrow portion 47 is the end of the side wall portion 421 opposite the end to which the side wall portion 411 is connected. The narrow portion 47 is the end of the side wall portion 421 formed by hemming, and has a very small width, so it is even less noticeable.

(2-3)変形例3
図5に示す変形例3の出隅構造1は、出隅部材2の形状が、実施形態と異なる。突出部4は、目地材収容部として、他方壁材側収容部42のみを有しており、一方壁材側収容部41(図1参照)を有していない。突出部4は、二つの接続部43,44に代えて、固定部3と他方壁材側収容部42とを接続する接続部48を有している。一方固定片31の外側の板状部分は、他方固定片32よりも他方固定片32の外面側に延び出ており、この延び出た部分が接続部48を構成している。接続部48は、一方固定片31と平行な平板状に形成されている。
(2-3) Modification 3
In the corner structure 1 of the modified example 3 shown in Fig. 5, the shape of the corner member 2 is different from that of the embodiment. The protruding portion 4 has only the other-wall material side storage portion 42 as a joint material storage portion, and does not have the one-wall material side storage portion 41 (see Fig. 1). The protruding portion 4 has a connection portion 48 that connects the fixed portion 3 and the other-wall material side storage portion 42 instead of the two connection portions 43, 44. The outer plate-shaped portion of the one-wall material side fixing piece 31 extends toward the outer surface side of the other-wall material side fixing piece 32 beyond the other-wall material side fixing piece 32, and this extended portion constitutes the connection portion 48. The connection portion 48 is formed in a flat plate shape parallel to the one-wall material side fixing piece 31.

他方壁材側収容部42の底部420は、接続部48において固定部3に接続された端部とは反対側の端部から接続部48の外面側に向かって突出している。底部420は、他方固定片32と平行な平板状に形成されている。 The bottom 420 of the other wall material side storage section 42 protrudes from the end of the connection section 48 opposite the end connected to the fixing section 3 toward the outer surface side of the connection section 48. The bottom 420 is formed in a flat plate shape parallel to the other fixing piece 32.

他方壁材側収容部42の側壁部421は、底部420において接続部48に接続された端部とは反対側の端部から底部420の外面側に向かって突出している。側壁部421は、一方固定片31と平行な平板状に形成されている。 The side wall portion 421 of the other wall material side storage portion 42 protrudes from the end of the bottom portion 420 opposite the end connected to the connection portion 48 toward the outer surface side of the bottom portion 420. The side wall portion 421 is formed in a flat plate shape parallel to the one fixing piece 31.

突出部4は、覆部49を更に有している。覆部49は、水平断面L字状に形成されており、幅狭片490と、幅広片491とを有している。幅狭片490は、側壁部421における底部420に接続された端部とは反対側の端部から側壁部421の外面側に向かって突出している。幅狭片490は、他方壁材側収容部42の底部420と平行な平板状に形成されている。 The protrusion 4 further has a covering portion 49. The covering portion 49 is formed in an L-shape in horizontal cross section, and has a narrow piece 490 and a wide piece 491. The narrow piece 490 protrudes toward the outer surface side of the side wall portion 421 from the end opposite the end connected to the bottom portion 420 of the side wall portion 421. The narrow piece 490 is formed in a flat plate shape parallel to the bottom portion 420 of the other wall material side storage portion 42.

幅広片491は、幅狭片490における出隅側の端部(側壁部421に接続された端部とは反対側の端部)から幅狭片490の内面側に向かって突出している。幅広片491は、他方壁材側収容部42の側壁部421と平行な平板状に形成されている。幅広片491の幅は、幅狭片490の幅よりも大きい。幅広片491における出隅とは反対側の端部(幅狭片490に接続された端部とは反対側の端部)は、自由端である。ただし、幅広片491において幅狭片490に接続された端部とは反対側の端部の内面側には、幅広片491を構成する板状部分を折り返して形成された折返部492が形成されている。折返部492は、例えば、幅広片491を構成する板状部分をヘミング加工することにより形成される。幅広片491において幅狭片490が接続された端部とは反対側の端部は、他方壁材側収容部42の底部420よりも、出隅とは反対側に向かって突出している。本変形例では、幅広片491が幅広部46であり、幅狭片490が幅狭部47である。 The wide piece 491 protrudes from the end of the narrow piece 490 on the protruding corner side (the end opposite to the end connected to the side wall portion 421) toward the inner side of the narrow piece 490. The wide piece 491 is formed in a flat plate shape parallel to the side wall portion 421 of the other wall material side storage portion 42. The width of the wide piece 491 is greater than the width of the narrow piece 490. The end of the wide piece 491 opposite to the protruding corner (the end opposite to the end connected to the narrow piece 490) is a free end. However, a folded portion 492 formed by folding back the plate-shaped portion constituting the wide piece 491 is formed on the inner side of the end of the wide piece 491 opposite to the end connected to the narrow piece 490. The folded portion 492 is formed, for example, by hemming the plate-shaped portion constituting the wide piece 491. The end of the wide piece 491 opposite the end to which the narrow piece 490 is connected protrudes toward the opposite side of the corner beyond the bottom 420 of the other wall material side storage section 42. In this modification, the wide piece 491 is the wide portion 46, and the narrow piece 490 is the narrow portion 47.

本変形例の出隅構造1は、バックアップ材81,82(図1参照)を備えていない。なお、出隅構造1は、上記実施形態と同様に、目地材72をバックアップするバックアップ材82を備えてもよい。 The corner structure 1 of this modified example does not include backup materials 81, 82 (see FIG. 1). Note that the corner structure 1 may include a backup material 82 that backs up the joint material 72, as in the above embodiment.

一方壁材61における出隅側の端部は、一方固定片31、接続部48、底部420及び幅広片491で構成され出隅とは反対側に向かって開口した凹部に嵌め込まれている。一方壁材61は、出隅側の端面が出隅部材2の他方壁材側収容部42の底部420に接した状態で、壁下地5に取り付けられている。本変形例の一方壁材用位置決部413は、他方壁材側収容部42の底部420である。幅広片491において幅狭片490に接続された端部とは反対側の端部は、一方壁材61における出隅側の端部の表面を覆っている。このため、一方壁材61と出隅部材2との間には、水が入り込み難い。 The end of the one wall material 61 on the protruding corner side is fitted into a recess formed by the one fixing piece 31, the connection part 48, the bottom part 420, and the wide piece 491, and opening toward the opposite side of the protruding corner. The one wall material 61 is attached to the wall base 5 with the end face on the protruding corner side in contact with the bottom part 420 of the other wall material side accommodation part 42 of the protruding corner member 2. The one wall material positioning part 413 of this modified example is the bottom part 420 of the other wall material side accommodation part 42. The end of the wide piece 491 opposite to the end connected to the narrow piece 490 covers the surface of the end of the one wall material 61 on the protruding corner side. For this reason, water is less likely to get in between the one wall material 61 and the protruding corner member 2.

他方壁材62は、出隅側の端面が、出隅部材2の接続部48に接した状態で壁下地5に取り付けられている。本変形例の他方壁材用位置決部423は、出隅部材2の接続部48である。他方壁材62の表面は、他方壁材62の厚み方向において、出隅部材2の幅狭片490の表面と同位置に位置している。 The other wall material 62 is attached to the wall base 5 with the end face on the protruding corner side in contact with the connection part 48 of the protruding corner member 2. The positioning part 423 for the other wall material in this modified example is the connection part 48 of the protruding corner member 2. The surface of the other wall material 62 is located at the same position as the surface of the narrow piece 490 of the protruding corner member 2 in the thickness direction of the other wall material 62.

本変形例の出隅構造1は、一方目地材71(図1参照)及び他方目地材72のうち、他方目地材72のみを備えている。他方目地材72は、他方壁材62の出隅側の端面と出隅部材2の側壁部421との間に形成された目地92の全体に充填されている。本変形例では、一方目地材71を省略でき、出隅構造1の施工が容易である。 The corner structure 1 of this modified example includes only the second joint material 72 out of the first joint material 71 (see FIG. 1) and the second joint material 72. The second joint material 72 fills the entire joint 92 formed between the end face on the corner side of the second wall material 62 and the side wall portion 421 of the corner member 2. In this modified example, the first joint material 71 can be omitted, making it easier to construct the corner structure 1.
