An exterior panel P made of ALC (lightweight cellular concrete) is attached to the outer peripheral wall of the building H as a finishing material. As the exterior panel P, the reference exterior panel 1 shown in FIG. 3 is used without being processed as it is or after being appropriately processed at a construction site.

基準外装パネル１は、工場生産された規格品であり、その幅Ｌは平面モジュールＭの整数（Ｎ、本実施例ではＮ＝４）倍となっている。基準外装パネル１には、平面モジュールＭを３等分(ｎ＝３)したピッチＰ(１５１．６７ｍｍ)で１１本の縦溝２が予め工場で刻まれている。この縦溝２は、断面矩形又は台形状に形成され、基準外装パネル１の両端には、縦溝２の幅の半分の幅寸法をもった半縦溝２ａが設けられている。そして、外装パネルＰ同士を幅方向に連接させると、半縦溝２ａ同士が接合されて合成縦溝３が形成され、この合成縦溝３は、底部に形成されたシールポケット３ｃに充填材６が注入された状態で、外観的に、縦溝２と同一となる(図２参照)。   The reference exterior panel 1 is a standard product produced in a factory, and its width L is an integer (N, N = 4 in this embodiment) times that of the planar module M. In the reference exterior panel 1, eleven vertical grooves 2 are preliminarily carved at the factory at a pitch P (151.67 mm) obtained by dividing the planar module M into three equal parts (n = 3). The vertical groove 2 is formed in a rectangular or trapezoidal cross section, and a semi-vertical groove 2 a having a width dimension that is half the width of the vertical groove 2 is provided at both ends of the reference exterior panel 1. When the exterior panels P are connected to each other in the width direction, the semi-longitudinal grooves 2a are joined together to form the composite longitudinal groove 3, and the composite longitudinal groove 3 is formed in the seal pocket 3c formed in the bottom portion with the filler 6. In the state in which is injected, it becomes the same as the longitudinal groove 2 in appearance (see FIG. 2).

図１に示すように、外周壁を構築する際の基準となる基準線Ｙ０，Ｙ１間の寸法（梁間寸法）Ｒは、平面モジュールＭの正数倍の値を有し、この建物Ｈの場合、寸法Ｒは、４５５ｍｍの２４倍の１０９２０ｍｍである。同様に基準線Ｙ０，Ｙ１に直交する基準線Ｘ０，Ｘ１（Ｘ１は不図示）間の寸法（桁行寸法）も平面モジュールＭの正数倍の値を有している。   As shown in FIG. 1, the dimension (inter-beam dimension) R between the reference lines Y0 and Y1, which is a reference when constructing the outer peripheral wall, has a value that is a multiple of the plane module M. The dimension R is 10920 mm, which is 24 times 455 mm. Similarly, the dimension (column dimension) between the reference lines X0 and X1 (X1 is not shown) orthogonal to the reference lines Y0 and Y1 has a value that is a multiple of the plane module M.

図２に示すように、建物Ｈの外周壁は、基準線Ｙ０（Ｙ１）に直交して水平に延在する基準線Ｘ０（Ｘ１）に基づいて構築された壁体１０と、壁体１０に所定の間隔で取り付けられた胴縁２０と、胴縁２０を下地としてビス固定により貼設された外装パネルＰと、によって構成されている。壁体１０は、その中心位置が基準線Ｙ０，Ｙ１，Ｘ０，Ｘ１に一致するように設定されており、平部用出隅パネルＰ１及び出隅用外装パネルＰ２，Ｐ３は、基準線Ｙ０，Ｙ１，Ｘ０，Ｘ１からの出寸法が一定の値Ｄ(例えば１３１ｍｍ)となるようにそれぞれ貼設されている。   As shown in FIG. 2, the outer peripheral wall of the building H includes a wall body 10 constructed based on a reference line X0 (X1) that extends perpendicularly to the reference line Y0 (Y1), and a wall body 10. It is comprised by the trunk | drum 20 attached by the predetermined | prescribed space | interval, and the exterior panel P stuck by screw fixing with the trunk | drum 20 used as a foundation | substrate. The wall body 10 is set so that the center position thereof coincides with the reference lines Y0, Y1, X0, and X1, and the flat portion protruding corner panel P1 and the protruding corner exterior panels P2 and P3 include the reference line Y0, They are pasted so that the projected dimensions from Y1, X0, and X1 are constant values D (eg, 131 mm).

布基礎の上面に立設される壁体１０は、壁式構造の建物において荷重の支持や地震力等の外力に対抗する要素として有効な構造壁として機能するものである。壁体１０の構成は、布基礎の上に配置される枠体１１と、２枚の石膏ボード１２ａ，１２ｂからなり枠体１１の建物内部側に固定される内装材１２と、枠体１１の建物外部側でビスに固定される構造用面材１３と、この構造用面材１３に貼設される板状断熱材１４と、この断熱材１４に貼設される透湿防水シート(不図示)とからなる。   The wall body 10 erected on the upper surface of the fabric foundation functions as a structural wall that is effective as an element that resists external forces such as load support and seismic force in a wall-type structure building. The structure of the wall body 10 includes a frame body 11 arranged on a cloth foundation, an interior material 12 made of two gypsum boards 12a and 12b and fixed to the inside of the frame body 11, and the frame body 11. A structural face member 13 fixed to a screw on the outside of the building, a plate-like heat insulating material 14 attached to the structural face member 13, and a moisture-permeable waterproof sheet (not shown) attached to the heat insulating material 14. ).

建物Ｈの平部（出隅部以外の中間部）に配置される平部用外装パネルＰ１（後述する出隅部用パネルに挟まれるように配置される外装パネル）の両端は、縦溝２の幅の半分の幅寸法をもった半縦溝２ａを有する。建物Ｈの平部に割り付けられる平部用外装パネルＰ１については、基準外装パネル１が基本的には切断されることなく使用され、端数が生ずる場合に限って縦溝２の位置で半縦溝２ａになるように切断されて使用される。   Both ends of the flat exterior panel P1 (exterior panel disposed so as to be sandwiched between the projected corner panels described later) disposed in the flat section (intermediate section other than the projected corner section) of the building H are the longitudinal grooves 2. The half longitudinal groove 2a has a width dimension that is half of the width. For the flat exterior panel P1 allocated to the flat part of the building H, the reference exterior panel 1 is basically used without being cut, and the half longitudinal groove is provided at the position of the longitudinal groove 2 only when a fraction occurs. It is cut into 2a and used.

建物Ｈの出隅部に配置される出隅用外装パネルＰ２，Ｐ３の一端は、基準外装パネルの縦溝の幅の半分の幅寸法をもった半縦溝２ａを有すると共に、平部用外装パネルＰ１の端部に突き合わされる。出隅用外装パネルＰ２，Ｐ３の他端は、平断面で４５度の角度となる小口８を有する。この出隅用外装パネルＰ２は、基準線Ｙ０と出隅用外装パネルＰ２の縦溝２の中心とが一致するように貼設されている。また、建物Ｈの出隅部に配置される他の出隅用外装パネルＰ３も、基準線Ｘ０と出隅用外装パネルＰ３の縦溝２の中心とが一致するように貼設されている。   One end of the exterior corner exterior panels P2 and P3 arranged at the exterior corner of the building H has a half longitudinal groove 2a having a width of half the longitudinal groove width of the reference exterior panel, and a flat exterior. It abuts against the end of the panel P1. The other ends of the exterior corner exterior panels P2, P3 have a fore edge 8 having a 45-degree angle in a plane cross section. The exterior corner exterior panel P2 is attached so that the reference line Y0 and the center of the longitudinal groove 2 of the exterior corner exterior panel P2 coincide. Further, the other exterior corner exterior panel P3 arranged at the exterior corner of the building H is also pasted so that the reference line X0 and the center of the vertical groove 2 of the exterior corner exterior panel P3 coincide.

出隅用外装パネルＰ２，Ｐ３は、基準外装パネル１を現場にて切り出したものであり、出隅用外装パネルＰ２，Ｐ３の表面側の幅寸法Ｌ１がＭ＋Ｄとされ、寸法Ｄは、出隅用外装パネルＰ２，Ｐ３が基準外装パネル１から（Ｎ−１）枚切り出されるように設定されている。すなわち、Ｄ＝Ｍ／(Ｎ−１)以下である。なおここでＬ１は、対向する小口８間に形成された湿式（不定形）シール材１５を充填する為の隙間や、尖端の面取りを考慮しない寸法である。   The exterior corner exterior panels P2 and P3 are obtained by cutting the reference exterior panel 1 on site, the width L1 on the surface side of the exterior corner exterior panels P2 and P3 is M + D, and the dimension D is the exit corner. The exterior exterior panels P2 and P3 are set to be cut out from the reference exterior panel 1. That is, D = M / (N-1) or less. In addition, L1 is a dimension which does not consider the clearance gap for filling the wet (indefinite shape) sealing material 15 formed between the opposite foreheads 8, and the chamfering of a point here.

具体的には、ｎ＝３の基準外装パネル１では、寸法Ｄの最大値は１５１．６７ｍｍとなるが、切断の際のロス（切断に使用する工具の厚みや切断面の仕上げ作業による欠損等）を考慮して寸法Dを１３０乃至１４０ｍｍ程度に設定している。また、ｎ＝４すなわち縦溝２のピッチＰが２２７．５ｍｍの場合は、寸法Ｄの最大値は１１３．７５ｍｍと求められ、実際の寸法Ｄとしては９０乃至１００程度に設定することができる。   Specifically, in the reference exterior panel 1 with n = 3, the maximum value of the dimension D is 151.67 mm, but loss during cutting (such as a thickness of a tool used for cutting or a defect due to a finishing operation of the cut surface) ), The dimension D is set to about 130 to 140 mm. When n = 4, that is, when the pitch P of the longitudinal grooves 2 is 227.5 mm, the maximum value of the dimension D is obtained as 113.75 mm, and the actual dimension D can be set to about 90 to 100.

図３に示した基準外装パネル１からの出隅用外装パネルの切り出し手順について図４を用いて具体的に説明すると、まず、基準外装パネル１をその両端からＭ＋Ｄの位置Ｃ１，Ｃ２で切断して２枚の出隅用外装パネルを得る。次に、残った基準外装パネル１をその一端から最初の縦溝２ａの中心位置Ｃ３で切断して半縦溝を形成し、更にＣ３からＭ＋Ｄの位置（Ｃ４）で切断することによって３枚目の出隅用外装パネルを得る。そして、ハッチで示した部分のみが廃棄あるいは他の用途にリサイクルされる。   The procedure of cutting out the exterior corner exterior panel from the reference exterior panel 1 shown in FIG. 3 will be described in detail with reference to FIG. 4. First, the reference exterior panel 1 is cut from both ends thereof at positions C1 and C2 of M + D. To obtain two exterior corner panels. Next, the remaining reference exterior panel 1 is cut from one end thereof at the center position C3 of the first vertical groove 2a to form a semi-longitudinal groove, and further cut at a position C3 to M + D (C4). Obtain the exterior corner panel. Only the hatched parts are discarded or recycled for other uses.

このようにすることで、基準外装パネル１から出隅用外装パネルＰ２，Ｐ３を無駄なく切り出すことができ、各出隅部に使用される部材やその納まりの共通化も達成することができる。   By doing in this way, the exterior corner exterior panels P2 and P3 can be cut out from the reference exterior panel 1 without waste, and it is possible to achieve common use of the members used in the exterior corners and their storage.

また、この外周壁構造においては、建物Ｈの全ての出隅部において、出隅部から最初の縦溝での寸法が、向かって右側の出隅用外装パネルＰ２と、向かって左側の出隅用外装パネルＰ３とで一致し、縦溝２の配列を左右対称の関係とすることができ、建物外観の意匠性を維持することができる。   Further, in this outer peripheral wall structure, in all the projecting corners of the building H, the dimensions of the first vertical groove from the projecting corners are the right projecting exterior panel P2 and the projecting left projecting corner. It matches with the exterior panel P3 for use, and the arrangement of the longitudinal grooves 2 can be a symmetrical relationship, and the design of the exterior of the building can be maintained.

また、留め納まり部Ｓにおいて、対向する一対の出隅用外装パネルＰ２，Ｐ３の切断面（小口８）に形成された隙間の離間寸法（Ａ）は、想定される地震力が作用した際の層間変形角の最大値に基づく離隔寸法（Ａ）を有しており、このように構成することにより、地震の際に、留め納まり部Ｓで隣接している出隅用外装パネルＰ２，Ｐ３同士の接触によるヒビや欠けなどの破損を防止することができる。   In addition, in the retaining portion S, the separation dimension (A) of the gap formed on the cut surface (small edge 8) of the pair of facing corner exterior panels P2, P3 is the same as that when the assumed seismic force is applied. It has a separation dimension (A) based on the maximum value of the interlayer deformation angle, and by configuring in this manner, the exterior corner exterior panels P2 and P3 that are adjacent to each other in the retaining portion S in the event of an earthquake It is possible to prevent breakage such as cracks and chippings caused by contact.

本発明は、前述した実施形態に限定されないことは言うまでもない。例えば、上記実施形態では、基準外装パネル１の横貼りを例示したが、基準外装パネル１を縦貼りする場合にも本発明は適用可能である。また、縦溝２は上記実施形態のような連続的なのものに限定はされず、馬目地（破れ目地）を模した不連続なものであってもよい。   It goes without saying that the present invention is not limited to the embodiment described above. For example, in the above embodiment, the horizontal attachment of the reference exterior panel 1 is illustrated, but the present invention is also applicable to the case where the reference exterior panel 1 is vertically attached. Moreover, the vertical groove 2 is not limited to a continuous thing like the said embodiment, The discontinuous thing which imitated horse joint (break joint) may be sufficient.
