The outer wall surface material has two orthogonal outer wall surfaces, and a plurality of the vertical furring strips are attached to each outer wall surface, and at least the vertical furring strip closest to the corner of each outer wall surface is the protruding corner. It is characterized in that it is provided so as to face the corner pillar of the (hereinafter referred to as the first configuration in this section).

上記の構成であれば、外壁面の少なくとも最もコーナー寄りの縦胴縁は隅柱に対向して位置するので、各外壁面の複数本の縦胴縁の配置間隔を適切に設定して、建物の出隅コーナー部において耐風に優れた外壁を構成することができる。また、一つの外壁パネルを建物の出隅コーナーに取り付ける作業によって、建物の出隅コーナーには、直交する二面の外壁面が一度に形成されることになり、外壁パネルの建物への設置の作業時間を短縮できる。 With the above configuration, at least the vertical furring strips closest to the corners of the outer wall surface are located facing the corner pillars. It is possible to form an outer wall having excellent wind resistance at the protruding corners of the building. In addition, by attaching one outer wall panel to the outer corner of the building, two orthogonal outer walls will be formed at the same time at the outer corner of the building, and the outer wall panel will be installed in the building. Working time can be shortened.

上記最もコーナー寄りの縦胴縁以外の縦胴縁のなかの一部の縦胴縁の丈が、上下のパネル連結に必要な丈よりも短くされていてもよい（以下、この項において第２構成という。）。これによれば、例えば、建物に設置する上下の外壁パネルにおける上記最もコーナー寄りの縦胴縁に隣接する縦胴縁同士の間を、上記の最もコーナー寄りの縦胴縁同士を接続するための作業用空間とすることができ、作業効率が向上する。また、作業者は、各階の床スラブ上で最もコーナー寄りの縦胴縁同士を接続する作業が行えるので、足場を不要にし得る。 The length of a part of the vertical furring strips other than the vertical furring strips closest to the corners may be shorter than the length required for connecting the upper and lower panels (hereinafter, the second in this section). It is called composition.). According to this, for example, in the upper and lower outer wall panels installed in a building, between the vertical furring strips adjacent to the vertical furring strips closest to the corners, and for connecting the vertical furring strips closest to the corners. It can be used as a work space, improving work efficiency. Further, since the worker can perform the work of connecting the vertical furring strips closest to the corners on the floor slab on each floor, the scaffolding can be unnecessary.

上記丈が短くされた縦胴縁は、上記隅柱における上記出隅コーナー側の角の隣の角の近傍に位置するのがよい（以下、この項において第３構成という。）。これによれば、上記の最もコーナー寄りの縦胴縁同士を接続するための作業用空間の位置の適切化が図れるとともに、各外壁面の複数本の縦胴縁の配置間隔の適切化が図れる。 The vertical furring strip having a shortened length is preferably located in the vicinity of the corner next to the corner on the protruding corner side of the corner pillar (hereinafter, referred to as the third configuration in this section). According to this, the position of the work space for connecting the vertical furring strips closest to the corners can be optimized, and the arrangement interval of the plurality of vertical furring strips on each outer wall surface can be optimized. ..

また、この発明の外壁構造は、上記第１構成の外壁パネルを建物の出隅コーナーに上下に配置して取り付ける外壁構造であって、上下の外壁パネルにおける対応する縦胴縁同士が接続板によって接続されていることを特徴とする。 Further, the outer wall structure of the present invention is an outer wall structure in which the outer wall panels of the first configuration are arranged and attached vertically to the outside corners of the building, and the corresponding vertical furring strips in the upper and lower outer wall panels are connected to each other by a connecting plate.

以下、この発明の実施の形態を添付図面に基づいて説明する。
図１に示すように、外壁パネル５は、複数の横長の外壁面材５１を上下に複数枚並べて下地材５２で相互に連結された構造を有する。図１に示す例では、上記下地材５２として縦胴縁５２ａを備えている。上記縦胴縁５２ａは、例えば、リップ溝型鋼からなる。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the outer wall panel 5 has a structure in which a plurality of horizontally long outer wall materials 51 are arranged one above the other and connected to each other by a base material 52. In the example shown in FIG. 1, the vertical furring strip 52a is provided as the base material 52. The vertical furring strip 52a is made of, for example, a lip channel steel.

上記外壁面材５１は、例えば、図２（Ａ）および図２（Ｂ）に示すように、不燃断熱材５１ａを鋼板５１ｂ、５１ｃで挟み込んだ金属サンドイッチパネルである。２枚の外壁面材５１を上下に並べた場合、下段に位置する外壁面材５１の上端面に形成された横幅方向に長い２か所の凹部５１ｄに、上段に位置する外壁面材５１の下端面に形成された横幅方向に長い２か所の凸部５１ｅが嵌まり込むことにより、上下の外壁面材５１が互いに面外方向に位置ずれしないように組み合わされる。なお、上記外壁パネル５を組み立てるための地組架台については、図示を省略する。 The outer wall surface material 51 is, for example, as shown in FIGS. 2A and 2B, a metal sandwich panel in which a noncombustible heat insulating material 51a is sandwiched between steel plates 51b and 51c. When two outer wall materials 51 are arranged one above the other, the outer wall material 51 located in the upper stage has two recesses 51d formed in the upper end surface of the outer wall material 51 located in the lower stage, which are long in the horizontal direction. By fitting the two convex portions 51e formed on the lower end surface in the lateral width direction, the upper and lower outer wall surface members 51 are combined so as not to be displaced from each other in the out-of-plane direction. The groundwork frame for assembling the outer wall panel 5 is not shown.

上記外壁パネル５は、建設中の建物１００（図３等参照）の出隅コーナーに取り付けられる。そして、上記外壁パネル５は平面視で略Ｌ字状を有し、上記外壁面材５１は直交する二面の外壁面を備えており、それぞれの外壁面には上記縦胴縁５２ａが複数本、この実施形態では３本取り付けられている。 The outer wall panel 5 is attached to the outside corner of the building 100 under construction (see FIG. 3 and the like). The outer wall panel 5 has a substantially L-shape in a plan view, the outer wall material 51 has two orthogonal outer wall surfaces, and each outer wall surface has a plurality of vertical furring strips 52a. , In this embodiment, three are attached.

また、上記外壁パネル５において、各外壁面の３本の縦胴縁５２ａのうち、最もコーナー寄りの縦胴縁５２ａ1は後述の隅柱１０１の側面に対向して位置する。また、上記最もコーナー寄りの縦胴縁５２ａ1に隣接する縦胴縁５２ａ2(中央側の縦胴縁)の丈は、上下のパネル連結に必要な丈よりも短くされている。一方、上記縦胴縁５２ａのうち、最もコーナー寄りの縦胴縁５２ａ1および最もコーナーから遠い縦胴縁５２ａ3の丈は、上下のパネル連結に必要な丈になっている。 Further, in the outer wall panel 5, of the three vertical furring strips 52a on each outer wall surface, the vertical furring strip 52a 1 closest to the corner is located facing the side surface of the corner pillar 101 described later. Further, the length of the vertical furring strip 52a 2 (vertical furring strip on the center side) adjacent to the vertical furring strip 52a 1 closest to the corner is shorter than the length required for connecting the upper and lower panels. On the other hand, among the vertical furring strips 52a, the lengths of the vertical furring strip 52a 1 closest to the corner and the vertical furring strip 52a 3 farthest from the corner are the lengths required for connecting the upper and lower panels.

次に、この実施形態の外壁構造および外壁施工方法について説明していく。図３および図４に示すように、建物１００の出隅コーナーには、隅柱１０１が設けられている。この隅柱１０１の下側には下階の床スラブ１０２が設けられており、上側には上階の床スラブ１０３が設けられている。上記外壁パネル５は、上記隅柱１０１を囲うように配置され、上側の一部分が上記下階の床スラブ１０２のフロア面から突き出して設けられる。また、上記外壁パネル５は、上記下階の床スラブ１０２に、図示しないファスナーによって固定される。また、上記外壁パネル５において、上記縦胴縁５２ａ2の水平方向位置は、後述の補助胴縁６２の取り付け等を考慮し、上記隅柱１０１における上記出隅コーナー側の角の隣の角の近傍にくるように配置されている。上記隅柱１０１の上記角部の近傍の範囲は、当該角部から幾分ブラインド側に近づいて上記隅柱１０１の側面と対面する範囲でもよいし、上記角部から幾分部屋側に出て上記隅柱１０１の側面から外れる範囲でもよい。 Next, the outer wall structure and the outer wall construction method of this embodiment will be described. As shown in FIGS. 3 and 4, corner pillars 101 are provided at the protruding corners of the building 100. A floor slab 102 on the lower floor is provided on the lower side of the corner pillar 101, and a floor slab 103 on the upper floor is provided on the upper side. The outer wall panel 5 is arranged so as to surround the corner pillar 101, and a part of the upper side thereof is provided so as to protrude from the floor surface of the floor slab 102 on the lower floor. Further, the outer wall panel 5 is fixed to the floor slab 102 on the lower floor by a fastener (not shown). Further, in the outer wall panel 5, the horizontal position of the vertical furring strip 52a 2 is the corner next to the corner on the protruding corner side of the corner pillar 101 in consideration of the attachment of the auxiliary furring strip 62 described later. It is arranged so that it comes close to it. The range in the vicinity of the corner portion of the corner pillar 101 may be a range that is slightly closer to the blind side from the corner portion and faces the side surface of the corner pillar 101, or is slightly out of the corner portion toward the room side. It may be a range that deviates from the side surface of the corner pillar 101.

そして、図５に示すように、上記外壁パネル５上に、地上の地組架台で作製しておいた別の外壁パネル５を、クレーン等で吊り上げ、既にファスナーで固定されている下側の外壁パネル５上に位置させる。このとき、下側の外壁パネル５の上記縦胴縁５２ａ2と上側の外壁パネル５の上記縦胴縁５２ａ2との間に、治具や腕が入るための、高さが略３５０ｍｍ程度の離間空間（作業用空間）が形成される。なお、上下の上記縦胴縁５２ａ1間および上記縦胴縁５２ａ3間には、例えば、３０ｍｍ程度の隙間（クリアランス）が生じる。 Then, as shown in FIG. 5, on the outer wall panel 5, another outer wall panel 5 made of the ground gantry on the ground is lifted by a crane or the like, and the lower outer wall already fixed with a fastener. Positioned on the panel 5. At this time, the height for inserting a jig or an arm between the vertical furring strip 52a 2 of the lower outer wall panel 5 and the vertical furring strip 52a 2 of the upper outer wall panel 5 is about 350 mm. A separated space (working space) is formed. A gap (clearance) of, for example, about 30 mm is formed between the upper and lower vertical furring strips 52a 1 and the vertical furring strips 52a 3 .

次に、図６および図７に示すように、上下の上記縦胴縁５２ａ1間および上記縦胴縁５２ａ3間には、平板状の接続板６１を配置し、これらに形成されている挿通孔にボルト等の締結部材を設けて相互に固定する。なお、上記縦胴縁５２ａ1、５２ａ3の端部には孔を形成しナットを溶接しておく。もちろん、ボルトを溶接しておいて、このボルトを接続板６１の挿通孔に通してナットを装着するようにしてもよい。上記接続板６１の配置や締結部材による固定操作は、上記縦胴縁５２ａ1間の作業用空間を利用して行うことができる。 Next, as shown in FIGS. 6 and 7, a flat plate-shaped connecting plate 61 is arranged between the upper and lower vertical furring strips 52a 1 and the vertical furring strips 52a 3 , and the insertion plates formed therein are inserted. A fastening member such as a bolt is provided in the hole to fix each other. Holes are formed at the ends of the vertical furring strips 52a 1 and 52a 3 , and nuts are welded to them. Of course, the bolt may be welded and the bolt may be passed through the insertion hole of the connection plate 61 to mount the nut. The arrangement of the connection plate 61 and the fixing operation by the fastening member can be performed by utilizing the work space between the vertical furring strips 52a 1 .

上下の縦胴縁５２ａ1間での上記接続板６１の配置や締結部材による固定を行った後、上記縦胴縁５２ａ2間の上記操作空間に、上記縦胴縁５２ａ2における丈が短くされた分を補う、リップ溝形鋼等からなる補助胴縁６２を配置する。さらに２枚の接続板６１を用い、これらに形成されている挿通孔にボルト等の締結部材を設けて相互に固定する。 After the connection plate 61 is arranged between the upper and lower vertical furring strips 52a 1 and fixed by the fastening member, the length of the vertical furring strip 52a 2 is shortened in the operating space between the vertical furring strips 52a 2 . An auxiliary furring strip 62 made of lip channel steel or the like is arranged to supplement the amount. Further, two connecting plates 61 are used, and fastening members such as bolts are provided in the insertion holes formed therein to fix them to each other.

そして、上下の上記縦胴縁５２ａ3間での上記接続板６１の配置や締結部材による固定を行い、さらに、図８に示すように、別の外壁パネル５を上側に取り付けていく。 Then, the connection plate 61 is arranged between the upper and lower vertical furring strips 52a 3 and fixed by the fastening member, and another outer wall panel 5 is attached to the upper side as shown in FIG.

上記の構成であれば、各外壁面の最もコーナー寄りの縦胴縁５２ａ1が隅柱１０１に対向して位置するので、各外壁面の複数本の縦胴縁５２ａの配置間隔を適切に設定して、建物１００の出隅コーナー部において耐風に優れた外壁を構成することができる。また、一つの上記外壁パネル５を建物の出隅コーナーに取り付ける作業によって、建物の出隅コーナーには、直交する二面の外壁面が一度に形成されることになり、外壁パネルの建物への設置の作業時間を短縮できる。 In the above configuration, the vertical furring strip 52a 1 closest to the corner of each outer wall surface is located facing the corner pillar 101, so that the arrangement interval of the plurality of vertical furring strips 52a on each outer wall surface is appropriately set. Therefore, it is possible to form an outer wall having excellent wind resistance at the protruding corners of the building 100. Further, by the work of attaching one outer wall panel 5 to the outer corner of the building, two orthogonal outer wall surfaces are formed at once in the outer corner of the building, and the outer wall panel can be attached to the building. Installation work time can be shortened.

また、上記最もコーナー寄りの縦胴縁５２ａ1に隣接する縦胴縁５２ａ2の丈が、上下のパネル連結に必要な丈よりも短くされていると、建物１００に設置する上下の外壁パネル５における上記最もコーナー寄りの縦胴縁５２ａ1に隣接する縦胴縁５２ａ2同士の間を、上記の最もコーナー寄りの縦胴縁５２ａ1同士を接続するための作業用空間とすることができ、作業効率が向上する。また、作業者は、各階の床スラブ上で最もコーナー寄りの縦胴縁同士を接続する作業が行えるので、足場を不要にし得る。 Further, if the length of the vertical furring strip 52a 2 adjacent to the vertical furring strip 52a 1 closest to the corner is shorter than the length required for connecting the upper and lower panels, the upper and lower outer wall panels 5 to be installed in the building 100 The space between the vertical furring strips 52a 2 adjacent to the vertical furring strips 52a 1 closest to the corners in the above can be used as a working space for connecting the vertical furring strips 52a 1 closest to the corners. Work efficiency is improved. Further, since the worker can perform the work of connecting the vertical furring strips closest to the corners on the floor slab on each floor, the scaffolding can be unnecessary.

さらに、上記丈が短くされた縦胴縁５２ａ2が、上記隅柱１０１における上記出隅コーナー側の角の隣の角の近傍に位置すると、上記の最もコーナー寄りの縦胴縁５２ａ1同士を接続するための作業用空間の位置の適切化が図れるとともに、各外壁面の複数本の縦胴縁５２ａの配置間隔の適切化が図れる。 Further, when the vertical furring strip 52a 2 having the shortened length is located in the vicinity of the corner next to the corner on the protruding corner side of the corner pillar 101, the vertical furring strips 52a 1 closest to the corner are separated from each other. The position of the work space for connection can be optimized, and the arrangement interval of the plurality of vertical furring strips 52a on each outer wall surface can be optimized.

なお、上記外壁パネル５において、上記縦胴縁５２ａ2の丈を他の縦胴縁と同じ長さとすることも可能である、この場合、上記縦胴縁５２ａ2の水平方向位置を、上記隅柱１０１における上記出隅コーナー側の角の隣の角から腕や治具が入る程度の距離だけ室内寄りに離間させるのがよい。これにより、上記最もコーナー寄りの縦胴縁５２ａ1における上記接続板６１の取り付けのための作業用空間を確保することができる。なお、この場合には、上記縦胴縁５２ａ2は上記縦胴縁５２ａ1から多少離れて位置することになる。また、上記の例では、最もコーナー寄りの縦胴縁５２ａ1に隣接する１本の縦胴縁５２ａ2の丈が短くされたが、これに限らず、上記縦胴縁５２ａ1と縦胴縁５２ａ2の間に他の縦胴縁が存在するような場合には、この他の縦胴縁においても丈が短くされる。すなわち、最もコーナー寄りの縦胴縁以外の縦胴縁のなかの一部（１本または複数本）の縦胴縁の丈が、上下のパネル連結に必要な丈よりも短くされていてもよい。 In the outer wall panel 5, the length of the vertical furring strip 52a 2 can be set to the same length as the other vertical furring strips. In this case, the horizontal position of the vertical furring strip 52a 2 is set to the corner. It is preferable to keep the pillar 101 closer to the room by a distance from the corner next to the corner on the protruding corner side so that an arm or a jig can be inserted. As a result, it is possible to secure a working space for attaching the connection plate 61 at the vertical furring strip 52a 1 closest to the corner. In this case, the vertical furring strip 52a 2 is located slightly away from the vertical furring strip 52a 1 . Further, in the above example, the length of one vertical furring strip 52a 2 adjacent to the vertical furring strip 52a 1 closest to the corner is shortened, but the length is not limited to this, and the vertical furring strip 52a 1 and the vertical furring strip 52a 1 are not limited to this. If there is another vertical furring strip between 52a 2 , the length of the other vertical furring strip is also shortened. That is, the length of a part (one or more) of the vertical furring strips other than the vertical furring strip closest to the corner may be shorter than the length required for connecting the upper and lower panels. ..
