Description

本発明は、外装材に関し、更に詳細には、断熱性、防水性、耐風性が高く、しかも、施工が容易な屋根材、壁材等として利用可能な外装材に関する。   The present invention relates to an exterior material, and more particularly, to an exterior material that has high heat insulating properties, waterproof properties, and wind resistance, and that can be used as a roof material, a wall material, and the like that are easy to construct.

従来より、家屋等の建築物に利用される薄板金属製の屋根材や、壁材等の外装材が種々市販されている。このような屋根材や壁材では、雨等を防ぎ、強風に対しても十分な強度を有するという基本的な機能の他、省エネ対策のために断熱機能の向上も求められている。   Conventionally, various types of exterior materials such as thin sheet metal roofing materials and wall materials used for buildings such as houses have been commercially available. In such roofing materials and wall materials, in addition to the basic function of preventing rain and the like and having sufficient strength against strong winds, improvement of the heat insulating function is also required for energy saving measures.

このような課題を解決するために、本発明者は、先に金属板と防水シートと断熱材とを一体化した瓦棒屋根葺材を考案し、特許出願した(特許文献1)。これにより、上記した問題の多くは解決できるが、特に夏場などは、太陽熱により高温になった金属板に断熱材が長時間接することにより、断熱材自体が蓄熱して熱の遮断効果が低下するという問題があった。   In order to solve such a problem, the present inventor previously devised and applied for a patent on a roof tile roof material in which a metal plate, a waterproof sheet, and a heat insulating material are integrated (Patent Document 1). As a result, many of the above-mentioned problems can be solved, but especially in summer, the heat insulating material contacts the metal plate heated to high temperature by solar heat for a long time, so that the heat insulating material itself stores heat and the heat blocking effect is reduced. There was a problem.

特開2002−61340JP 2002-61340 A

従って本発明は、十分な耐風強度を有しながら、断熱機能に優れ、しかも施工の容易な屋根材、壁材等の外装材の提供をその課題とするものである。   Accordingly, an object of the present invention is to provide an exterior material such as a roof material and a wall material that has a sufficient wind resistance strength, is excellent in a heat insulating function, and is easy to construct.

本発明者は、上記課題を解決すべく検討を行い、金属板に形成された防水層と断熱材層との間に通気溝を形成することにより、金属板が空冷され、断熱材の蓄熱も抑えられることを見出し、本発明を完成した。   The inventor has studied to solve the above problems, and by forming a ventilation groove between the waterproof layer and the heat insulating material layer formed on the metal plate, the metal plate is cooled by air, and the heat storage of the heat insulating material is also performed. As a result, the present invention was completed.

すなわち本発明は、矩形の金属板の裏面に防水層及び断熱材層を順次積層した板部材と、複数の該板部材を下地に対し連結固定する吊子とからなる縦葺用外装材であって、前記吊子は、吊子本体の上部を前後の少なくとも一方へ水平ないし水平以下に突出するよう折り曲げ形成した返し片と、本体中間端部を前後の少なくとも一方へ略水平に突出するよう折り曲げ形成した係止片と、本体下部を下地面と平行になるよう折り曲げ形成した固定部とを備え、前記板部材の辺部であって連結される板部材と隣接する少なくとも一の辺部には、前記吊子の返し片と係止片との間に嵌め込み可能な立ち上がり部が設けられ、更に、前記防水層と前記断熱材層との間には通気溝を備えていることを特徴とする縦葺用外装材である。   That is, the present invention is an upright covering material comprising a plate member in which a waterproof layer and a heat insulating material layer are sequentially laminated on the back surface of a rectangular metal plate, and a hanging member for connecting and fixing a plurality of the plate members to a base. The hanging part is bent so that the upper part of the hanging body is bent so as to protrude horizontally or below horizontally to at least one of the front and back, and the intermediate end of the body is bent substantially horizontally to at least one of the front and rear. And a fixing portion formed by bending the lower portion of the main body so as to be parallel to the base surface, and at least one side portion adjacent to the plate member to be connected which is a side portion of the plate member. In addition, a rising portion that can be fitted between the return piece and the locking piece of the hanging member is provided, and a ventilation groove is provided between the waterproof layer and the heat insulating material layer. It is an exterior material for downspout.

また本発明は、断熱材層が不燃系断熱材およびウレタンフォーム系断熱材からなる少なくとも二層の断熱材層に形成された前記外装材である。   Moreover, this invention is the said exterior material in which the heat insulating material layer was formed in the at least 2 layer heat insulating material layer which consists of a nonflammable heat insulating material and a urethane foam type heat insulating material.

さらに本発明は、金属板の裏面に防水層及び断熱材層を介して断面凹凸状に折り曲げ形成された金属下地板を設けた前記外装材である。   Furthermore, the present invention is the above exterior material in which a metal base plate is formed on the back surface of the metal plate by bending it into a concavo-convex shape through a waterproof layer and a heat insulating material layer.

本発明の外装材によれば、防水層と断熱材層との間に形成された通気溝内を空気が通気することにより、金属板が空冷され断熱材の蓄熱も抑えられるため、熱の遮断効果が向上し、その結果、より効率的に断熱効果を得ることができる。   According to the exterior material of the present invention, the air is ventilated in the ventilation groove formed between the waterproof layer and the heat insulating material layer, so that the metal plate is air-cooled and the heat storage of the heat insulating material is also suppressed. As a result, the heat insulation effect can be obtained more efficiently.

また、本発明の外装材は、板部材の辺部に設けられた立ち上がり部を吊子の返し片と係止片との間に嵌合させることにより、板部材を上下より挟持して固定可能であるため、台風などの突風などに対しても十分な強度を有する。   Further, the exterior material of the present invention can be fixed by sandwiching the plate member from above and below by fitting the rising portion provided on the side portion of the plate member between the return piece of the hanging member and the locking piece. Therefore, it has sufficient strength against gusts such as typhoons.

また、本発明の外装材で断熱材が不燃系断熱材およびウレタンフォーム系断熱材の二層から形成されるものは、火災等で飛び火が発生した場合も、上記通気溝および不燃系断熱材によって、断熱材本体への損傷を防止することができる。   Also, in the case of the exterior material according to the present invention, the heat insulating material is formed from two layers of a non-combustible heat insulating material and a urethane foam heat insulating material. It is possible to prevent damage to the heat insulation body.

さらに、本発明の外装材で金属板の裏面に防水層及び断熱材層を介して断面凹凸状に折り曲げ形成された金属下地板を設けたものは、上述のような断熱効果・火災による損傷防止効果をより向上させることができるとともに、従来の野地板等の下地が不要となるため、コスト削減・工期短縮が可能となる。   Further, the exterior material of the present invention provided with a metal base plate bent to have a concavo-convex shape with a waterproof layer and a heat insulating material layer provided on the back surface of the metal plate has the above heat insulation effect and fire damage prevention. The effect can be further improved, and a base such as a conventional base plate is not required, so that cost reduction and construction period can be shortened.

以下、本発明外装材のいくつかの態様を示す図面と共に本発明を説明する。   Hereinafter, the present invention will be described together with drawings showing some embodiments of the exterior packaging material of the present invention.

図1は、本発明外装材の第1の態様の板部材を示す断面図、図2は吊子の斜視図、図3はキャップ部材の断面図、図4は板部材を連結した状態を表す断面図である。図中、1は板部材、2は吊子、3は金属板、4は防水層、5は断熱材層、6は通気溝、7はキャップ部材、21は返し片、22はハゼ部、23は係止片、24は固定部、31は立ち上がり部、32はハゼ部、51は不燃系断熱材、52はウレタンフォーム系断熱材、73は金属板、74は防水層をそれぞれ示す。   FIG. 1 is a cross-sectional view showing a plate member of the first aspect of the exterior packaging material of the present invention, FIG. 2 is a perspective view of a hanging member, FIG. 3 is a cross-sectional view of a cap member, and FIG. It is sectional drawing. In the figure, 1 is a plate member, 2 is a hanging member, 3 is a metal plate, 4 is a waterproof layer, 5 is a heat insulating material layer, 6 is a ventilation groove, 7 is a cap member, 21 is a return piece, 22 is a haze portion, 23 Is a locking piece, 24 is a fixing part, 31 is a rising part, 32 is a goby part, 51 is a non-combustible heat insulating material, 52 is a urethane foam heat insulating material, 73 is a metal plate, and 74 is a waterproof layer.

本発明外装材の板部材1は基本的に矩形に形成されており、図1では左右両側が長手辺となる。図に示すように、板部材1はその金属板3の裏面全域にわたって防水層4を、また立ち上がり部を除く裏面に断熱材層5を積層させた構造をなし、金属板3の両側の長手辺部には、立ち上がり部31が形成されている。立ち上がり部31は金属板3の長手辺部からやや外側に傾斜し、中間部からは、ほぼ垂直に立ち上がるように形成されており、その上端から内側へ向けてハゼ部32が折り曲げ形成されている。   The plate member 1 of the exterior packaging material of the present invention is basically formed in a rectangular shape, and the left and right sides are longitudinal sides in FIG. As shown in the figure, the plate member 1 has a structure in which a waterproof layer 4 is laminated over the entire back surface of the metal plate 3 and a heat insulating material layer 5 is laminated on the back surface excluding the rising portion. A rising portion 31 is formed in the part. The rising portion 31 is inclined slightly outward from the longitudinal side portion of the metal plate 3 and is formed so as to rise substantially vertically from the intermediate portion, and a goby portion 32 is bent from the upper end to the inside. .

断熱材層5は、不燃系断熱材51およびウレタンフォーム系断熱材52を積層した構造をなし、このうち、防水層4に接する不燃系断熱材51には、断面凹状に形成された通気溝6が、板部材1の長手方向に複数並行するように設けられている。このように、断熱材層5を不燃系断熱材51およびウレタンフォーム系断熱材52の二層としたことにより、火災等で飛び火が発生した場合も、通気溝6および不燃系断熱材51によって、断熱材本体への損傷を防止することができる。また、通気溝6により、太陽の熱により暖まった金属板3の熱を直接伝熱せず、空気を介して伝熱するため、断熱性能を向上させることができる。さらに、通気性を高め、内側から発生する結露水や水蒸気を蒸散し、外部に排気することで、内部結露による金属板3に対する腐食等を防止することができる。   The heat insulating material layer 5 has a structure in which a non-combustible heat insulating material 51 and a urethane foam heat insulating material 52 are laminated. Among these, the non-combustible heat insulating material 51 in contact with the waterproof layer 4 has a ventilation groove 6 formed in a concave cross section. Are provided in parallel with each other in the longitudinal direction of the plate member 1. Thus, by making the heat insulating material layer 5 into two layers of the non-flammable heat insulating material 51 and the urethane foam heat insulating material 52, even when a spark is generated due to a fire or the like, the ventilation groove 6 and the non-flammable heat insulating material 51 It is possible to prevent damage to the heat insulating material body. Moreover, since the heat | fever of the metal plate 3 warmed with the heat of the sun is not directly transmitted by the ventilation groove 6, but heat is transmitted via air, heat insulation performance can be improved. Furthermore, by increasing the air permeability, the condensed water or water vapor generated from the inside is evaporated and exhausted to the outside, thereby preventing corrosion or the like on the metal plate 3 due to internal condensation.

図2に示すように、吊子2は、矩形板状の本体の上部に、水平以下の角度に折り曲げ形成された返し片21が、前後方向へ互い違いに突出するように2箇所設けられている。返し片21の先端側には、一旦吊子本体側へ折り返された後、曲線を描きながら下方へ向けて延設するハゼ部22が設けられている。また、吊子本体の中間端部からは、ほぼ水平に折り曲げ形成した係止片23が、上部の返し片21と同一方向へ突出するように2箇所設けられている。さらに、吊子本体の下部には、下地面と平行になるよう一方向へと折り曲げ形成された固定部24が設けられている。   As shown in FIG. 2, the hanging piece 2 is provided at two places on the upper portion of the rectangular plate-like main body so that the return pieces 21 bent and formed at an angle below horizontal are alternately projected in the front-rear direction. . On the tip end side of the return piece 21, a goby portion 22 is provided that is once folded back to the hanging body side and then extends downward while drawing a curve. In addition, from the intermediate end portion of the hanging body, two locking pieces 23 formed so as to be bent substantially horizontally are provided so as to protrude in the same direction as the upper return piece 21. Further, a fixing portion 24 that is bent in one direction so as to be parallel to the base surface is provided at the lower portion of the hanging body.

図4に示すように、板部材1の立ち上がり部31は、板部材1を連結した状態で、吊子2の返し片21および係止片23との間に嵌め込み可能な形状に形成されている。具体的には、吊子2の係止片23に立ち上がり部31の下端部を係止させたときに、ハゼ部32の上面に返し片21の下面側が密接するように形成されている。これにより、金属板3は連結時に上下から支持されことになる。さらに、この状態で、キャップ部材7を返し片21に冠着することにより、板部材1と吊子2は一体的に固定される。図に示すように、キャップ部材7は、金属板73の裏面に防水層74が形成され、返し片21にほぼ密接して冠着可能な形状に形成されている。   As shown in FIG. 4, the rising portion 31 of the plate member 1 is formed in a shape that can be fitted between the return piece 21 and the locking piece 23 of the hanging member 2 in a state where the plate member 1 is connected. . Specifically, the lower surface side of the return piece 21 is formed in close contact with the upper surface of the goby portion 32 when the lower end portion of the rising portion 31 is engaged with the engaging piece 23 of the hanging element 2. As a result, the metal plate 3 is supported from above and below when connected. Further, in this state, the plate member 1 and the suspension 2 are integrally fixed by attaching the cap member 7 to the barb 21. As shown in the figure, the cap member 7 has a waterproof layer 74 formed on the back surface of the metal plate 73, and is formed in a shape that can be crowned in close contact with the return piece 21.

本発明において使用される金属板3、73としては、例えば、チタン亜鉛合金、亜鉛めっき鋼板、アルミニウム亜鉛合金めっき鋼板、ステンレス鋼板、塩化ビニル鋼板、銅板等の金属板が挙げられ、これらは予め塗装されていても良い。この金属板の大きさは特に制約はなく、扱いやすさやデザイン性を考慮し、現場合わせで適切な大きさとすればよい。   Examples of the metal plates 3 and 73 used in the present invention include metal plates such as a titanium zinc alloy, a galvanized steel plate, an aluminum zinc alloy plated steel plate, a stainless steel plate, a vinyl chloride steel plate, and a copper plate. May be. The size of the metal plate is not particularly limited, and may be set to an appropriate size on site according to ease of handling and design.

上記金属板の裏側に形成される防水層4、74は、雨水漏や、結露による金属板3に対する腐食等を防止する。使用される防水層としては、アスファルト系や改質アスファルト系、合成ゴム系、樹脂系等の防水層等が挙げられ、これらは、接着剤の塗布、自着粘着槽の積層、熱融着等により形成することができる。   The waterproof layers 4 and 74 formed on the back side of the metal plate prevent rainwater leakage and corrosion of the metal plate 3 due to condensation. Examples of waterproof layers used include asphalt-based, modified asphalt-based, synthetic rubber-based, and resin-based waterproof layers. These include adhesive application, self-adhesive adhesive tank lamination, thermal fusion, etc. Can be formed.

また、防水層4、74に積層させる断熱材としては、種々のプラスチック素材、例えばウレタンフォーム系のほか、ポリイソシアヌレートフォーム、フェノールフォームなどのプラスチック発泡素材や、不燃系発泡素材を好ましく利用することができる。   Moreover, as a heat insulating material laminated on the waterproof layers 4 and 74, various plastic materials, for example, urethane foams, plastic foam materials such as polyisocyanurate foams and phenol foams, and incombustible foam materials are preferably used. Can do.

図5は、本実施態様の外装材の取り付け方法について示したものである。図に示すように、あらかじめ耐火野地板等の下地8に固定ビス25により取り付けられた吊子2に対し、立ち上がり部31のハゼ部32部分を吊子2の返し片21とハゼ部22の内側へと挿入し、そのまま立ち上がり部31が返し片21および係止片23との間に嵌め込まれるよう板部材1の取り付け位置を調整する。次に、板部材1が連結されていない辺部側に、新たに吊子2を取り付ける。このときは、立ち上がり部31のハゼ部32部分に対し吊子2の返し片21とハゼ部22を被せるようにし、次に係止片23を立ち上がり部31の下端に係止させ、固定部24を固定ビス25によって下地8に固定すればよい。次に、上記と同じ手順で吊子2の反対側に板部材1を取り付け、最後に、キャップ部材7を返し片21に被せることにより、2枚の板部材1と吊子2を固定する。以下、この作業の繰り返しにより、本発明の外装材で屋根を葺くことができる。   FIG. 5 shows a method of attaching the exterior material according to this embodiment. As shown in the figure, with respect to the hanger 2 attached in advance to the base 8 such as a fireproof ground plate by a fixing screw 25, the goby portion 32 of the rising portion 31 is placed inside the return piece 21 and the goby portion 22 of the hanger 2. The mounting position of the plate member 1 is adjusted so that the rising portion 31 is fitted between the return piece 21 and the locking piece 23 as it is. Next, the hanging element 2 is newly attached to the side part to which the plate member 1 is not connected. At this time, the return piece 21 and the goby portion 22 of the suspension 2 are covered with the goby portion 32 of the rising portion 31, and then the locking piece 23 is locked to the lower end of the rising portion 31 to fix the fixing portion 24. May be fixed to the base 8 with a fixing screw 25. Next, the plate member 1 is attached to the opposite side of the hanging member 2 in the same procedure as described above, and finally, the two plate members 1 and the hanging member 2 are fixed by covering the cap member 7 on the return piece 21. Hereinafter, the roof can be spread with the exterior material of the present invention by repeating this operation.

なお、上記の施工例は、あらかじめ工場で断熱材層5が金属板3に一体的に形成されている短尺ものの施工の場合に適切である。しかしながら、板部材1が長尺に形成されている場合には、あらかじめ工場で断熱材層5を金属板3に形成すると運搬などに支障をきたす場合がある。その場合には、金属板3への断熱材層5の取り付けを現場で行うことも可能である。具体的には、まず、耐火野地板等の下地8に吊子2を固定し、次に断熱材層5を下地8に接着して固定する。そして、金属板3を現場合わせで加工し、吊子2に対して取り付け、最後にキャップ部材7によって固定すればよい。   In addition, said construction example is suitable in the case of the construction of the short thing in which the heat insulating material layer 5 was integrally formed in the metal plate 3 beforehand in the factory. However, when the plate member 1 is formed long, if the heat insulating material layer 5 is formed on the metal plate 3 in advance at the factory, it may hinder transportation. In that case, the heat insulating material layer 5 can be attached to the metal plate 3 on site. Specifically, first, the hanger 2 is fixed to the base 8 such as a fireproof ground plate, and then the heat insulating material layer 5 is bonded and fixed to the base 8. Then, the metal plate 3 may be processed on-site, attached to the hanger 2, and finally fixed by the cap member 7.

次に、本発明外装材の第3の態様について説明する。このタイプのものは壁材としての利用に適している。図9は本実施態様の板部材の断面図、図10は吊子の斜視図、図11は板部材を連結した状態を表す断面図である。図に示すように、この態様の板部材1は、立ち上がり部31が金属板3の一方の長手辺部にのみ形成され、他方の長手辺部には、通気溝61から一旦、斜め下方向へ傾斜し、その先より水平方向へ突出する差込部33が形成されている。そして、立ち上がり部直近の通気溝62の壁面下部には、かかる差込部33を挿入可能な受け部34が凹状に形成されている。また、板部材を複数連結したときに、差込部33が設けられた通気溝61は連結される板部材の立ち上がり部31および吊子2に被さるように形成されている。   Next, the 3rd aspect of this invention exterior material is demonstrated. This type is suitable for use as a wall material. FIG. 9 is a cross-sectional view of the plate member of this embodiment, FIG. 10 is a perspective view of a hanging member, and FIG. 11 is a cross-sectional view showing a state in which the plate members are connected. As shown in the figure, in the plate member 1 of this aspect, the rising portion 31 is formed only on one longitudinal side portion of the metal plate 3, and the other longitudinal side portion is once inclined obliquely downward from the ventilation groove 61. The insertion part 33 which inclines and protrudes in the horizontal direction from the tip is formed. A receiving portion 34 into which the insertion portion 33 can be inserted is formed in a concave shape at the lower portion of the wall surface of the ventilation groove 62 immediately adjacent to the rising portion. Further, when a plurality of plate members are connected, the ventilation groove 61 provided with the insertion portion 33 is formed so as to cover the rising portion 31 and the suspension 2 of the connected plate member.

吊子2は、矩形板状の本体の上部にほぼ水平に折り曲げ形成された返し片21が、板状の一方側へ突出するように設けられている。返し片21の先端側は下方へ折り返された後、更に、本体側、そして上方へと折り返されたハゼ部22が設けられている。また、板状の本体の中間端部からは、ほぼ水平方向に折り曲げ形成した係止片23が、返し片21と同じ側へ突出するように設けられている。さらに、板状の本体の下部には、返し片21と反対側へ折り曲げ形成された固定部24が設けられている。   The hanging piece 2 is provided so that a return piece 21 bent substantially horizontally at the upper part of a rectangular plate-shaped main body protrudes to one side of the plate shape. After the front end side of the return piece 21 is folded downward, a goby portion 22 is further provided that is folded back to the main body side and upward. Further, a locking piece 23 bent in a substantially horizontal direction is provided from the middle end of the plate-like main body so as to protrude to the same side as the return piece 21. Further, a fixing portion 24 is provided at the lower portion of the plate-like main body and is bent to the opposite side of the return piece 21.

次に、この板部材1の取り付け方法について説明する。まず、下地に対して板部材1を所定の位置にセットした後に、吊子2を取り付ける。取り付け方法は、吊子2の返し片21およびハゼ部22から立ち上がり部31のハゼ部32に嵌めこみ、係止片23を防水層4と不燃系断熱材51との間に挿入する。この状態で、吊子2を固定ビス25により、下地8に固定すればよい。次に、図12に示すように、連結させる部板材1の差込部33を予め取り付けられている壁材の受け部34に挿入しながら、通気溝61を、立ち上がり部31および吊子2に被せて、所定の位置に納める。そして、吊子2により他方の端部を固定すればよい。以下、この作業の繰り返しにより、本発明の外装材で壁面を葺くことができる。   Next, a method for attaching the plate member 1 will be described. First, after the plate member 1 is set at a predetermined position with respect to the base, the hanger 2 is attached. The attachment method is such that the return piece 21 and the gouge part 22 of the hanging element 2 are fitted into the gouge part 32 of the rising part 31, and the locking piece 23 is inserted between the waterproof layer 4 and the non-combustible heat insulating material 51. In this state, the hanger 2 may be fixed to the base 8 with the fixing screw 25. Next, as shown in FIG. 12, while inserting the insertion part 33 of the part plate 1 to be connected into the receiving part 34 of the wall material attached in advance, the ventilation groove 61 is formed in the rising part 31 and the suspension 2. Put it over and put it in place. And what is necessary is just to fix the other edge part with the hanger 2. FIG. Hereinafter, by repeating this operation, the wall surface can be spread with the exterior material of the present invention.

次に、本発明外装材の第4の態様について説明する。図13は本実施態様の板部材を連結した状態を表す断面図である。図に示すように、断熱材層5は、不燃系断熱材51がウレタンフォーム系断熱材52を上下より挟み込んで積層した三層構造となっている。このため、断熱材層5の防火機能がより向上している。さらに、従来の野地板等の下地の代わりに、下地として断面凹凸形状に形成されて通気溝6を備えた金属下地板9が設けられている。かかる金属下地板9は、規格により寸法が決まっているベニヤ板等の下地とは異なりその寸法を任意に決めることができ、また、断面凹凸形状により耐荷重性能が高い。したがって、ベニヤ板等を下地に使用したときよりも母屋のC鋼10のスパンを広くとることができ、結果的に資材コストの削減と、工期短縮を図ることができる。   Next, the 4th aspect of this invention exterior material is demonstrated. FIG. 13 is a cross-sectional view illustrating a state in which the plate members of this embodiment are connected. As shown in the figure, the heat insulating material layer 5 has a three-layer structure in which a non-combustible heat insulating material 51 is laminated by sandwiching a urethane foam heat insulating material 52 from above and below. For this reason, the fireproof function of the heat insulating material layer 5 is further improved. Further, instead of a base such as a conventional base plate, a metal base plate 9 having a vent groove 6 formed in a concavo-convex shape as a base is provided. Unlike the base material such as a veneer plate whose dimensions are determined according to the standard, the metal base plate 9 can arbitrarily determine the dimensions, and has a high load bearing performance due to the concavo-convex shape. Therefore, the span of the C-steel 10 of the purlin can be made wider than when the veneer board or the like is used as the base, and as a result, the material cost can be reduced and the construction period can be shortened.

更に、上述の金属下地板9において、その上面に不燃系断熱材層を一体的に設けた第5の態様について、説明する。図14は、断面凹凸形状に形成されて通気溝6を備えた金属下地板9の上面に不燃系断熱材層91を一体的に設けたものの断面図である。図15は、このタイプの金属下地板9を連結し、更に板部材1を取り付けた状態を表す断面図である。図に示すように、この金属下地板9は、不燃系断熱材層91の上から通気溝6を通して固定ビス101によって下地のC鋼10に取り付けられている。取り付けられる板部材1は、断熱材層5が不燃系断熱材51とウレタンフォーム系断熱材52からなる二層タイプのものであり、板部材1を固定する吊子2は、連結する金属下地板9の端同士が重なり合った部分に固定ビス25にて固定されている。   Furthermore, the 5th aspect which provided the nonflammable heat insulating material layer integrally in the upper surface in the above-mentioned metal base plate 9 is demonstrated. FIG. 14 is a cross-sectional view of a non-combustible heat insulating material layer 91 that is integrally provided on the upper surface of a metal base plate 9 that has a cross-sectional concavo-convex shape and has ventilation grooves 6. FIG. 15 is a cross-sectional view showing a state in which this type of metal base plate 9 is connected and the plate member 1 is further attached. As shown in the figure, the metal base plate 9 is attached to the base C steel 10 by a fixing screw 101 through the ventilation groove 6 from above the non-combustible heat insulating material layer 91. The plate member 1 to be attached is of a two-layer type in which the heat insulating material layer 5 is composed of a non-combustible heat insulating material 51 and a urethane foam heat insulating material 52, and the suspension 2 for fixing the plate member 1 is a metal base plate to be connected. 9 is fixed to a portion where the ends of 9 are overlapped with a fixing screw 25.

この態様の金属下地板9を使用して施工した場合、C鋼10に対して、金属下地板9を不燃系断熱材層91の上からビス止めが可能となるため施工が容易となり、また、かかるビスが屋内側に露出することがないため、仕上がり的にもより好ましい。   When construction is performed using the metal base plate 9 of this embodiment, the C base 10 can be screwed from above the non-combustible heat insulating material layer 91 with respect to the C steel 10, and the construction becomes easy. Since such a screw is not exposed to the indoor side, it is more preferable in terms of finish.

本発明の外装材は、雨を防ぎ、流し落とすという基本的な機能の他、防寒・保温機能、防火機能など屋根板としての十分な機能および突風等に対する十分な強度を有するものであり、しかも施工の容易なものである。   The exterior material of the present invention has a sufficient function as a roof plate such as a cold protection / heat insulation function, a fire prevention function and a sufficient strength against a gust of wind in addition to a basic function of preventing and draining rain, Easy to install.

従って、本発明の外装材は、一般住宅用を始め多くの施設において、防水性、断熱性、防火性、耐風強度の優れた屋根材や壁材として広く利用可能なものである。   Therefore, the exterior material of the present invention can be widely used as a roof material or a wall material excellent in waterproofness, heat insulating property, fireproof property, and wind resistance strength in many facilities including general housing.
