Description

本発明は、建築物の屋根や壁に施工される縦葺き（縦張り）外装材及び外装構造にあって、主に施工性、雨仕舞性能、強度性能、構造及び作業者の安全性を高次元でバランス良く併せ持つ建築用縦葺き外装材、及び縦葺き外装構造に関する。   The present invention relates to a vertical (extended) exterior material and exterior structure to be constructed on a roof or wall of a building, and mainly improves workability, rain performance, strength performance, structure and worker safety. TECHNICAL FIELD The present invention relates to an architectural vertical facing exterior material having a well-balanced dimension and a vertical facing exterior structure.

雨仕舞性能を有し、且つ熱による幅方向の伸縮を吸収する建築用縦葺き外装材として、特許文献１に記載の屋根葺材が提案されている。この屋根葺材は、その左右側縁に略鉛直状の内側立上り部（係合防水壁）を有し、且つその外側に外側立上り部（防水壁）を有する構成であり、横方向に隣接して並設した前記屋根葺材の側部上に、接続材を跨がるように固定し、さらに接続材カバーで上方を覆って外装構造をなしている。前記接続材は、下地への固定部（水平部）の左右に略鉛直状の垂直壁及び防水脚片を有し、この垂直壁を屋根葺材の両立上り部間に、防水脚片を屋根葺材の内側立上り部の内側に位置させて上方から屋根葺材を押圧保持している。前記外装構造では、屋根葺材の係合防水壁と防水壁との間及び接続材の垂直壁と防水脚片との間にそれぞれ広幅の空間が形成されているので、屋根葺材の側縁は接続材に対して幅方向に摺動することができ、直射日光や気温変化によって屋根葺材が伸縮してもこの変化を吸収するので浮き上がりや固定部分の破断が生ずることがない。
しかし、この構造では、屋根葺材が押圧保持されているので、施工後における負圧作用時に、屋根葺材が浮き上がり押圧状態が外れ、屋根葺材が飛散する恐れがあった。また、接続材の固定は、屋根板を敷設した後にしかできないため、接続材を固定するまでの間、屋根板は下地上に単に載置されただけの状態となる。この屋根板は面積が大きいため風圧を受け易いので、突風により煽られたり、捲られて外部への落下事故を生じたり、或いは作業者の転落という人身事故につながる虞があった。また、前記事故は生じないまでも、屋根板の長さに対して作業者の数が少ないと、屋根板の局部的な変形を生じてその修正が必要となったり、取付けのための位置調整（墨出し線に合わせる作業）に時間を要する結果、作業工程に不測の遅延を生じさせることがあった。 The roof covering material described in Patent Document 1 has been proposed as a vertical roofing exterior material for building that has rain performance and absorbs expansion and contraction in the width direction due to heat. This roof covering has a substantially vertical inner rising portion (engagement waterproof wall) on the left and right side edges, and has an outer rising portion (waterproof wall) on the outer side thereof, and is adjacent to the lateral direction. On the side part of the roof covering material arranged side by side, it is fixed so as to straddle the connecting material, and further, the upper part is covered with a connecting material cover to form an exterior structure. The connecting member has a substantially vertical vertical wall and waterproof leg pieces on the left and right sides of the fixed portion (horizontal portion) to the base, and the waterproof leg pieces are attached to the roof covering material between the vertical walls and the compatible ascending portion of the roof covering material. The roof covering material is pressed and held from above by being positioned inside the inner rising portion. In the exterior structure, a wide space is formed between the engaging waterproof wall and the waterproof wall of the roofing material and between the vertical wall and the waterproofing leg piece of the connecting material, so the side edges of the roofing material are connected. It can slide in the width direction with respect to the material, and even if the roofing material expands or contracts due to direct sunlight or changes in temperature, this change is absorbed, so there is no lifting or breakage of the fixed part.
However, in this structure, since the roof covering material is pressed and held, the roof covering material is lifted and the pressed state is released during the negative pressure action after the construction, and the roof covering material may be scattered. Further, since the connection member can be fixed only after the roof plate is laid, the roof plate is simply placed on the ground until the connection member is fixed. Since this roof plate has a large area and is susceptible to wind pressure, there is a risk that it will be blown by a gust of wind, accidentally dropped to the outside, or a personal accident such as an operator falling. In addition, even if the accident does not occur, if the number of workers is small relative to the length of the roofing board, local deformation of the roofing board may be caused and correction thereof may be required, or position adjustment for installation may be performed. As a result of the time required for (matching the ink line), an unexpected delay may occur in the work process.

特公平２−５６４６４号公報Japanese Examined Patent Publication No. 2-56464

そこで、本発明では、前述の問題を生ずることがなく、施工作業を容易且つ安全に行えて工期の短縮及びコストの低減を図ることができ、風雨に対しても信頼性の高い外装構造を得ることができる外装材及び外装構造を提案することを目的とする。   Therefore, in the present invention, the above-described problem does not occur, construction work can be performed easily and safely, the construction period can be shortened and the cost can be reduced, and a highly reliable exterior structure against wind and rain is obtained. It aims at proposing the exterior material and exterior structure which can be performed.

本発明は、上記実状に鑑み提案されたもので、予め外装下地上に所定間隔で設置された保持部材間に配設する建築用縦葺き外装材であって、中央に面板部を、その左右側縁に保持部材に保持される内側立上り部を備えると共に、前記内側立上り部の外側には導水溝を介して外側立上り部を備え、前記外側立上り部には、保持部材に保持される係合部を備え、さらに一方の外側立上り部の外方には、敷設状態において隣り合う縦葺き外装材の他方の外側立上り部に被嵌状に重合する重合部を延設したことを特徴とする建築用縦葺き外装材に関するものである。   The present invention has been proposed in view of the above-described actual circumstances, and is a vertical casing exterior material for construction that is disposed between holding members that are previously installed on an exterior base at a predetermined interval, and has a face plate portion at the center, An inner rising portion held by a holding member is provided on a side edge, and an outer rising portion is provided outside the inner rising portion via a water guide groove, and the outer rising portion is engaged by a holding member. And an outer portion of one outer rising portion, and a superposed portion that overlaps with the other outer rising portion of the adjacent vertical wall covering material in the laid state is extended. The present invention relates to a vertical covering material.

また、本発明は、上記の縦葺き外装材を敷設してなることを特徴とする縦葺き外装構造をも提案する。   In addition, the present invention also proposes a vertical casing structure characterized by laying the above-described vertical casing material.

さらに、本発明は、敷設状態において重合部と裏面側に位置する外側立上り部との間に弾性シール材を設けたことを特徴とする前記縦葺き外装構造をも提案するものである。   Furthermore, the present invention also proposes the above-mentioned vertical casing structure characterized in that an elastic sealing material is provided between the overlapping portion and the outer rising portion located on the back surface side in the laid state.

本発明の建築用縦葺き外装材は、内側立上り部が保持部材の起立部に保持されることにより、風の吹き上げ等に抗する負圧強度が向上し、カバー材を用いないので部品点数が少なくなるため管理が容易となり、またコストの低減、施工性の向上が図られる。雨水等は、内側立上り部の内側の面板部にて軒側へ流下するが、強風雨等により内側立上り部を越える雨水が生じたとしても、内側立上り部の外側に設けられた導水溝により、浸入雨水を円滑に軒方向に流下させて軒先から排出することができるので、雨仕舞性能が高い。また、一方の外側立上り部に延設した重合部を他方の外側立上り部に被嵌状に重合させて外装構造を構築できるため、施工作業を容易に行えて工期の短縮及びコストの低減を図ることができ、さらに風雨によるまくれ上がりや、塵・埃等の堆積を防ぐことができ、総じて風雨に対して信頼性の高いものとなる。さらに、縦葺き外装材は、予め外装下地上に割り付け固定した保持部材に敷設するものであって、しかも内側立上り部及び外側立上り部をそれぞれに保持部材に保持させるので、敷設後の位置調整が不要であり、保持部材に強固且つ安定に保持されるものとなり、施工性が高く、施工時の突風等に対する安全性も高いものとなる。
このように本発明の縦葺き外装材、及びそれを用いて施工した外装構造は、施工性、雨仕舞性能、及び作業者の安全性といった諸性能を高次元でバランスさせたものとなり、安全に対する社会全般的な認識の高まりにも配慮したものとなる。 Since the vertical rising exterior material for building of the present invention has the inner rising portion held by the rising portion of the holding member, the negative pressure strength against wind blowing and the like is improved and the cover material is not used, so the number of parts is reduced. Since the number is reduced, management becomes easy, cost is reduced, and workability is improved. Rainwater, etc. flows down to the eaves side at the face plate part inside the inner rising part, but even if rainwater that exceeds the inner rising part occurs due to strong wind rain, etc., due to the water guide groove provided outside the inner rising part, Infiltration rainwater can flow smoothly in the direction of the eaves and be discharged from the eaves, resulting in high rain performance. In addition, since the exterior structure can be constructed by superimposing the overlapped part extended on one outer rising part on the other outer rising part, the construction work can be easily performed, and the construction period can be shortened and the cost can be reduced. Further, it is possible to prevent the wind and rain from turning up and the accumulation of dust, dust, etc., and it is generally highly reliable against wind and rain. Furthermore, the vertical facing exterior material is laid on a holding member that is previously allocated and fixed on the exterior base, and the inner rising portion and the outer rising portion are respectively held by the holding member, so that the position adjustment after laying can be performed. It is unnecessary and is firmly and stably held by the holding member, has high workability and high safety against gusts during construction.
As described above, the vertical covering material of the present invention, and the exterior structure constructed using the same, balances various performances such as workability, rain performance, and worker safety at a high level. It will also take into account the growing awareness of society as a whole.

また、本発明の外装構造は、縦葺き外装材の内側立上り部を保持部材の起立部に嵌合保持させることにより、吹上風圧力による負荷重や豪雪時の正荷重作用時の縦葺き外装材の働き幅中央方向への変位及び変形を抑制できるので、強度性能に優れた外装構造を提供することができる。さらに、上記嵌合保持によって、縦葺き外装材の内側立上り部より外側の構成の塑性変形を防止でき、並びに保持部材への保持、弾性取付けに影響を及ぼすことがなく、雨仕舞や保持関係の機能が安定に維持できる。   In addition, the exterior structure of the present invention is such that the inner rising part of the vertical casing is fitted and held to the rising part of the holding member, so that the vertical casing is applied when a load is applied due to blowing wind pressure or when a positive load is applied during heavy snowfall. Since the displacement and deformation | transformation to the working width center direction can be suppressed, the exterior structure excellent in the strength performance can be provided. Furthermore, the above-mentioned fitting and holding can prevent plastic deformation of the configuration outside the inner rising portion of the vertical covering material, and does not affect the holding and elastic attachment to the holding member. The function can be maintained stably.

さらに、特に重合部の裏面側に弾性シール材を設けた本発明の縦葺き外装構造は、万一塵や埃、雨水等が重合部の下端から重力に反して入ってくることがあったとしても、それ以上の内部への侵入を確実に防ぐことができる。   Furthermore, in particular, the vertical casing structure of the present invention in which an elastic sealing material is provided on the back side of the overlapped part is assumed that dust, dust, rainwater, etc. may enter from the lower end of the overlapped part against the gravity. However, it is possible to reliably prevent further intrusion into the interior.

本発明の建築用縦葺き外装材は、前記のように予め外装下地上に所定間隔で設置された保持部材間に配設するものであり、中央に面板部を、その左右側縁に保持部材に保持される内側立上り部を備えると共に、内側立上り部の外側には導水溝を介して外側立上り部を備え、外側立上り部には、保持部材に保持される係合部を備える構成である。ここまでの構成は、左右略対称であるが、一方の外側立上り部の外方には、敷設状態において隣り合う縦葺き外装材の他方の外側立上り部に被嵌状に重合する重合部を延設した構成である。他方の外側立上り部は、先端（上端を）内側に折り返した形状である。
そして、この縦葺き外装材を用いて外装構造を構築する場合には、基本的にカバー材を用いることなく、一方の外側立上り部に形成した重合部を、隣接する縦葺き外装材の他方の外側立上り部に被嵌状に重合させて外装構造を得る。 As described above, the vertical facing exterior material for building according to the present invention is disposed between the holding members that are previously installed on the exterior base at predetermined intervals, and the face plate portion is provided at the center, and the holding members are provided on the left and right side edges thereof. The inner rising portion is held on the outer rising portion, the outer rising portion is provided on the outside of the inner rising portion via a water guide groove, and the engaging portion held by the holding member is provided on the outer rising portion. The configuration so far is substantially symmetrical, but on the outside of one outer rising portion, a superposed portion that overlaps with the other outer rising portion of the adjacent vertical casing is extended in the laid state. It is the structure which was set. The other outer rising portion has a shape that is folded back inward at the tip (upper end).
And when constructing an exterior structure using this vertical facing exterior material, basically without using a cover material, the overlapped part formed on one outer rising portion is the other of the adjacent vertical facing exterior materials. The outer structure is obtained by superposing the outer rising portion in a fitting manner.

It is molded from a known metal material such as a lead plate, a carbon fiber laminated plate, a hard resin plate or the like. When the material is a metal plate, it is molded (molded) by roll molding, press molding, or a combination of both. When the material is a non-metallic material, it is mainly molded by mold molding. The material thickness is not particularly limited, but is about 0.4 to 1.6 mm.

図示した実施形態では面板部１１は、中立軸の近傍に形成されている。このように面板部１１を中立軸上又は中立軸の近傍に形成すると、図示しないが外装下地４が曲面の建築物に追従させるための曲面加工を容易且つ美麗に行うことができる。
尚、面板部１１には、必要に応じて図１（ｃ），（ｄ）に示すような長さ調整、変形防止等の目的で段状に***する調整部１６を設けてもよい。この調整部１６を一箇所或いは複数箇所に設けることにより、例えば必要に応じて段部を上方から叩いて平坦状に変形させることにより、幅を広くして敷設してもよい。 In the illustrated embodiment, the face plate portion 11 is formed in the vicinity of the neutral shaft. When the face plate portion 11 is formed on the neutral axis or in the vicinity of the neutral axis in this manner, the curved surface processing for allowing the exterior base 4 to follow the curved building can be performed easily and beautifully (not shown).
Note that the face plate portion 11 may be provided with an adjustment portion 16 that protrudes in a step shape for the purpose of length adjustment, deformation prevention, and the like as shown in FIGS. By providing this adjusting part 16 at one place or a plurality of places, for example, if necessary, the step part may be struck from above to be deformed into a flat shape, so that the width may be increased.

また、面板部１１の左右側縁に設けられた内側立上り部１２は、略鉛直状であり、面板部１１の側縁を上方に立ち上げた内側部分とその上端を下方へ折り返した外側部分とからなり、その裏面側には上方が閉塞する空間が形成されている。尚、面板部１１の裏面及び内側立上り部１２の裏面空間には、図２（ｂ）に示すように結露防止及び防音対策上、ポリエチレンフォーム等の裏貼り材１７が添装されている。
この内側立上り部１２の外側には導水溝１３が設けられ、この導水溝１３の底部は、中立軸より低く、即ち面板部１１よりも低い位置に形成されている。 Further, the inner rising portions 12 provided on the left and right side edges of the face plate portion 11 are substantially vertical, and an inner portion in which the side edges of the face plate portion 11 are raised upward and an outer portion in which the upper end is folded downward. A space whose upper side is closed is formed on the back side. In addition, as shown in FIG.2 (b), the back surface material 17 of polyethylene foam etc. is attached to the back surface space of the back surface of the faceplate part 11, and the inner side rising part 12, as shown in FIG.2 (b).
A water guide groove 13 is provided outside the inner rising portion 12, and a bottom portion of the water guide groove 13 is formed at a position lower than the neutral shaft, that is, lower than the face plate portion 11.

導水溝１３，１３の外側には外側立上り部１４，１４'が設けられ、これら外側立上り部１４，１４'は、外方に向かって傾斜状に形成され、中間には、内方に屈曲し、再び外方へ屈曲した形状の係合部１４１，１４１'が設けられている。尚、これらの外側立上り部１４，１４'は、その上半の構成が非対称であるため、異なる符号を付して区別した。このうち、一方の外側立上り部１４’の外方には、敷設状態において隣り合う外装材１の他方の外側立上り部１４に被嵌状に重合する重合部１５が延設され、他方の外側立上り部１４は、その上端を内方側から折り返した構成である。前記重合部１５は、外側立上り部１４'の上端を外側へ折り返し状に折曲し、係合部１４１より下方の位置に、略く字状の重合係合部１５１を設け、その下端を外側へ延在させた構成であって、敷設状態においては内側方向へ弾性抗力が作用するように形成されている。   Outer rising portions 14 and 14 'are provided outside the water guide grooves 13 and 13, and the outer rising portions 14 and 14' are formed to be inclined outward and bent inward in the middle. , Engaging portions 141 and 141 ′ which are bent outward again are provided. These outer rising portions 14 and 14 'are distinguished by attaching different reference numerals because the upper half of the configuration is asymmetric. Among these, outside the one outer rising portion 14 ′, an overlapping portion 15 that overlaps with the other outer rising portion 14 of the adjacent exterior material 1 in the laid state is extended, and the other outer rising portion 14 is extended. The part 14 has a configuration in which the upper end is folded back from the inner side. The overlapping portion 15 bends the upper end of the outer rising portion 14 ′ outward, and is provided with a substantially square overlapping engaging portion 151 at a position below the engaging portion 141. In the laid state, the elastic drag acts in the inner direction.

図２の外装構造に用いられる保持部材２は、左右に上向きの起立部２１，２１を有し、該起立部２１，２１の内側に平坦部分２２，２２を、さらに中央に上端が上向き矢印状の中央起立片２３を有する。この中央起立片２３の左右には楔状の被係合部２４，２４が形成されている。この保持部材２は、アルミや硬質樹脂による押出成形品、メッキ鋼板、ステンレス鋼板等のプレス加工品及びセラミック等よりなり、短尺なピース材であっても長尺であっても良い。この保持部材２を外装下地４上に固定する場合には、平坦部分２２，２２を固定部としてもよいし、起立部２１，２１の外側に位置する平坦状の部分を固定部としてもよく、接着剤やビス等を用いて固定すればよい。   The holding member 2 used in the exterior structure of FIG. 2 has upright standing portions 21 and 21 on the left and right sides, flat portions 22 and 22 inside the standing portions 21 and 21, and an upper end in an upward arrow shape at the center. The central upright piece 23 is provided. Wedge-like engaged portions 24, 24 are formed on the left and right of the central upright piece 23, respectively. The holding member 2 is made of an extruded product made of aluminum or hard resin, a pressed product such as a plated steel plate or a stainless steel plate, ceramic, or the like, and may be a short piece material or a long piece material. When fixing the holding member 2 on the exterior base 4, the flat portions 22 and 22 may be fixed portions, or the flat portions located outside the standing portions 21 and 21 may be fixed portions. What is necessary is just to fix using an adhesive agent or a screw.

前記保持部材２を固定する外装下地４は、木造、鉄骨造、コンクリート造等、釘、ビス、アンカー等の固定具が取付可能な全ての建築躯体を用いることができ、前記躯体上に断熱その他の必要に応じて敷設する木毛セメント板等のボード類を含む。   As the exterior base 4 for fixing the holding member 2, it is possible to use all building frames to which fixing tools such as nails, screws, anchors, etc. can be attached, such as wooden structures, steel structures, concrete structures, etc. Includes boards such as wood wool cement boards to be installed as needed.

図２の外装構造は、外装下地２上に、所定の間隔で前記構成の保持部材２を設置（割り付け）、固定し、横方向に隣接する保持部材２，２間に、前記構成の縦葺き外装材１を敷設、固定し、横方向に隣接する縦葺き外装材１の外側立上り部１４に被嵌状に重合部１５を重合した構造である。   In the exterior structure of FIG. 2, the holding member 2 having the above configuration is installed (allocated) and fixed on the exterior base 2 at a predetermined interval, and the vertical structure having the above configuration is disposed between the holding members 2 and 2 adjacent in the lateral direction. The outer packaging material 1 is laid and fixed, and the overlapping portion 15 is superposed on the outer rising portion 14 of the longitudinally facing outer packaging material 1 adjacent in the lateral direction.

縦葺き外装材１の敷設に際し、内側立上り部１２の裏面側空間内に前記保持部材２の起立部２１を位置させると共に、外側立上り部１４（１４'）の係合部１４１（１４１'）と前記保持部材２の被係合部２４とを弾性的に係合させ、外側立上り部１４，１４'の上方部分を前記保持部材２の中央起立片２３の頭部に沿わせる。この時、縦葺き外装材１の内側立上り部１２は、保持部材２の起立部２１により嵌合状に保持されているので、働き幅方向の伸縮応力を遮断し、その外側の導水溝１３や外側立上り部１４（１４'）及び重合部１５に働き幅方向の動きが生ずることがない。そして、面板部１１は、中央部分が下方に凹む凹面状になるように敷設されている。このような面板部１１の凹面状化により通常時に最も顕在化するポケットウェーブ現象を非顕在化し、意匠性を高めることができる。   When laying the vertical casing 1, the rising portion 21 of the holding member 2 is positioned in the space on the back surface of the inner rising portion 12, and the engaging portion 141 (141 ′) of the outer rising portion 14 (14 ′) The engaged portion 24 of the holding member 2 is elastically engaged with the upper portion of the outer rising portions 14 and 14 ′ along the head of the central standing piece 23 of the holding member 2. At this time, since the inner rising portion 12 of the vertical casing 1 is held in a fitted state by the rising portion 21 of the holding member 2, the stretching stress in the working width direction is blocked, and the outer water guide groove 13 and The outer rising portion 14 (14 ') and the overlapping portion 15 work and no movement in the width direction occurs. And the faceplate part 11 is laid so that the center part may become the concave shape dented below. By making the face plate portion 11 concave as described above, the pocket wave phenomenon that is most apparent in normal times can be made invisible and the design can be improved.

さらに、一方の外側立上り部１４'に延設された重合部１５を、横方向に隣接する縦葺き外装材１の外側立上り部１４に被嵌状に重合させるが、より具体的には係合部１４１の下方に至るように成形した重合係合部１５１を、係合部１４１の下方で弾性的に取付け固定する。尚、前述のように内側立上り部１２が起立部２１に保持されるため、働き幅方向の伸縮応力を遮断されるため、外側立上り部１４（１４'）の保持、及び重合部１５の弾性取付けに影響を及ぼすことがなく、安定に固定することができる。   Further, the overlapping portion 15 extended to one outer rising portion 14 'is overlapped with the outer rising portion 14 of the longitudinally facing outer packaging material 1 adjacent in the lateral direction. The overlapping engaging portion 151 formed to reach the lower portion of the portion 141 is elastically attached and fixed below the engaging portion 141. Since the inner rising portion 12 is held by the rising portion 21 as described above, the stretching stress in the working width direction is blocked, so that the outer rising portion 14 (14 ′) is held and the overlapping portion 15 is elastically attached. Can be stably fixed.

また、重合部１５と裏面側に位置する外側立上り部１４との間に弾性シール材３を設けるようにした。この弾性シール材３は、塵や埃の侵入を防止する目的としてはどのような弾性材料でもよいが、雨水等の浸入を防止する場合には、シリコーンゴムなどの非透水性の弾性シール材料を用いることが好ましい。図示実施例では、再上端における重合部１５の裏面側に弾性シール材３を設けているが、万一塵や埃、雨水等が重合部１５の下端から重力に反して入ってくることがあったとしても、それ以上の内部への侵入を確実に防ぐことができる。   Further, the elastic sealing material 3 is provided between the overlapping portion 15 and the outer rising portion 14 located on the back surface side. The elastic sealing material 3 may be any elastic material for the purpose of preventing dust or dust from entering, but in order to prevent the intrusion of rainwater or the like, a non-permeable elastic sealing material such as silicone rubber is used. It is preferable to use it. In the illustrated embodiment, the elastic sealing material 3 is provided on the back side of the overlapping portion 15 at the upper end. However, in the unlikely event that dust, dust, rainwater, or the like enters from the lower end of the overlapping portion 15 against gravity. Even if this occurs, it is possible to reliably prevent further intrusion.

このように施工された本発明の外装構造において、外装材１は、内側立上り部１２，１２より内側の面板部１１にて雨水等を軒側へ流下させることができ、強風雨等により内側立上り部１２を越える雨水が生じても、導水溝１３により浸入雨水を円滑に軒方向に流下させて軒先から排出することができ、雨仕舞性能が高い。さらに、一方の外側立上り部１４'に延設した重合部１５を他方の外側立上り部１４に被嵌状に重合させて外装構造を構築できるため、カバー材等を用いる必要がなく、施工作業を容易に行えて工期の短縮及びコストの低減を図ることができ、さらに風雨によるまくれ上がりや、塵・埃等の堆積を防ぐことができ、総じて風雨に対して信頼性の高いものとなる。
また、外装材１は、予め外装下地４上に割り付け、固定した保持部材２に敷設するものであり、しかも内側立上り部１２及び外側立上り部１４（１４'）をそれぞれに保持部材２に保持させるので、敷設後の位置調整が不要であり、保持部材２に強固且つ安定に保持されるものとなり、施工性が高く、施工時の突風等に対する安全性も高いものとなる。 In the exterior structure of the present invention thus constructed, the exterior material 1 can cause rainwater or the like to flow down to the eaves side at the face plate portion 11 inside the inner rising portions 12 and 12, and the inner rising due to strong wind and rain. Even if rainwater exceeding the portion 12 is generated, the intrusion rainwater can be smoothly flowed in the direction of the eaves through the water guide grooves 13 and discharged from the eaves, and the rain performance is high. Furthermore, since the exterior structure can be constructed by superimposing the overlapping portion 15 extending on one outer rising portion 14 'on the other outer rising portion 14 in a fitting manner, it is not necessary to use a cover material or the like, and the construction work can be performed. The construction period can be easily shortened and the cost can be reduced. Further, it is possible to prevent the wind-up and the accumulation of dust, dust, etc., and it is generally highly reliable against the wind and rain.
Moreover, the exterior material 1 is laid on the holding member 2 that is allocated and fixed in advance on the exterior base 4, and the inner rising portion 12 and the outer rising portion 14 (14 ') are held by the holding member 2, respectively. Therefore, position adjustment after laying is unnecessary, and the holding member 2 is firmly and stably held, so that the workability is high and the safety against gusts and the like during construction is also high.

さらに、図示実施例の外装構造では、重合部１５の裏面側に弾性シール材３を設けたので、万一塵や埃、雨水等が重合部の下端から重力に反して入ってくることがあったとしても、それ以上の内部への侵入を確実に防ぐことができる。   Furthermore, in the exterior structure of the illustrated embodiment, since the elastic sealing material 3 is provided on the back side of the overlapping portion 15, in the unlikely event that dust, dust, rainwater, or the like enters from the lower end of the overlapping portion against the gravity. Even if this occurs, it is possible to reliably prevent further intrusion.
