屋根や壁は、建築物の主要な部位をしめており、複雑で厳しい機能が求められている。従来から、屋根用部材として、薄肉の金属板が平板のまま、あるいは複雑な形状に加工されて用いられている。とくに、工場、倉庫等の屋根には、波型に折り曲げた形状の金属製折板を用いた屋根材が用いられることが多い。
例えば、特許文献1には、梁に図8に示すような波型に折り曲げた形状の金属製折板20の上に、耐火材21、断熱材22および防水層23を順次積層してなる屋根構造1が提案されている。特許文献1に記載された技術では、金属製折板20の上に耐火材21と断熱材22を敷き詰めて、断熱材22の上から、頭部に円盤状のディスク盤を設けた固定金具24(ビス)を用いて金属製折板20に機械的に固定し、次に、断熱材22の上に防水シート(層)23を敷設してディスク盤表面と防水シート裏面を接着して屋根構造を形成している。
Roofs and walls are the main parts of buildings, and complex and demanding functions are required. Conventionally, as a roof member, a thin metal plate is used as a flat plate or processed into a complicated shape. In particular, roofs made of metal folded plates bent into corrugations are often used for roofs of factories and warehouses.
For example, Patent Document 1 discloses a roof in which a refractory material 21, a heat insulating material 22, and a waterproof layer 23 are sequentially laminated on a metal folded plate 20 bent into a corrugated shape as shown in FIG. Structure 1 has been proposed. In the technique described in Patent Document 1, a refractory material 21 and a heat insulating material 22 are laid on a metal folded plate 20, and a fixing bracket 24 having a disk-shaped disk disk on the head from above the heat insulating material 22.

しかしながら、特許文献3に記載された技術では、屋根用部材の幅方向端部同士を突き合わせて接続する接続端の位置が、屋根用部材の下側、すなわちフラット部と略同レベルにあるため、とくに工事中に降雨があると、フラット部の上に雨水が溜まり易く、しかも溜まった雨水が接続端間のわずかな隙間から漏れる場合があるという問題があった。さらに、特許文献3に記載された技術では、屋根の軽量化要求に対応して、屋根用部材の構成材料である金属板の板厚を薄くしすぎると、断熱材を固定する止め具と金属板との間の接合強度が低下するという問題があった。   However, in the technique described in Patent Document 3, the position of the connecting end that connects the end portions in the width direction of the roof member is connected to the lower side of the roof member, that is, substantially the same level as the flat portion. In particular, when there is rainfall during construction, there is a problem that rainwater tends to accumulate on the flat portion, and the accumulated rainwater may leak from a slight gap between the connection ends. Furthermore, in the technique described in Patent Document 3, if the plate thickness of the metal plate, which is a constituent material of the roof member, is made too thin in response to a request for reducing the weight of the roof, a metal plate and a metal fixture for fixing the heat insulating material. There was a problem that the bonding strength between the plates was lowered.

本発明は、上記した従来技術の問題を解決し、平坦な天井面を容易に形成でき、かつ天井内装面の美観性や、断熱効果、遮音効果にも優れ、さらに工事中の止水性に優れ、また、止め金具と屋根用部材との接合強度を高めることが可能な、屋根用部材および屋根構造を提案することを目的とする。   The present invention solves the above-mentioned problems of the prior art, can easily form a flat ceiling surface, is excellent in the aesthetics of the ceiling interior surface, heat insulation effect, sound insulation effect, and also excellent in water-stopping during construction Another object of the present invention is to propose a roof member and a roof structure capable of increasing the bonding strength between the stopper metal and the roof member.

本発明者らは、上記した目的を達成するために、屋根用部材の接続端の形状について、鋭意研究した。その結果、接続端をフラット部より高い位置に配設し、断熱材の受け部と共用とすることがよいことに想到した。これにより、工事中の止水性は問題なくなる。そして、さらに、断熱材の止め金具と屋根用部材との接合強度を高めるために、屋根用部材の断熱材受け部相当位置で金属板が重なり合う構造とすることがよいことに思い至った。本発明は、上記した考えに基づき、さらに検討を加えて完成されたものである。   In order to achieve the above-described object, the present inventors diligently studied the shape of the connection end of the roof member. As a result, it was conceived that the connection end should be arranged at a position higher than the flat part and shared with the heat insulating material receiving part. This eliminates the problem of water-stopping during construction. Furthermore, in order to increase the bonding strength between the heat-insulating metal fastener and the roof member, it has been thought that it is preferable to have a structure in which the metal plates overlap at a position corresponding to the heat-insulating material receiving portion of the roof member. The present invention has been completed with further studies based on the above-described idea.

The plated steel sheet is preferably a galvanized steel sheet from the viewpoint of corrosion resistance.
An example of the roof member of the present invention is shown in FIG. 1A is a perspective view, and FIG. 1B is a cross-sectional view in the width direction. The roof member 1 of the present invention includes a flat portion 11 and a connection end 12. The connection end 12 includes a pair of a female connection end portion 12a and a male connection end portion 12b.

雌型の接続端部12aは、フラット部11の一方の端で上方に突設されて、フラット部11の長手方向に連続して延びる接続端支持部121aと、接続端支持部121aの上端に連続して形成される平坦部12a1とからなる。雌型の接続端部12aにおける平坦部12a1は、上面がフラット部11とほぼ平行でかつフラット部11の長手方向に延びる平坦面122aを有し、しかも接続端支持部121aの上端と反対側の端に雄型の接続端部12bの平坦部12b1の端を抑えるための張出し12a2を有することが好ましい。   The female connection end portion 12a protrudes upward at one end of the flat portion 11, and is connected to the connection end support portion 121a extending continuously in the longitudinal direction of the flat portion 11, and the upper end of the connection end support portion 121a. And a flat portion 12a1 formed continuously. The flat portion 12a1 in the female connection end portion 12a has a flat surface 122a whose upper surface is substantially parallel to the flat portion 11 and extends in the longitudinal direction of the flat portion 11, and is opposite to the upper end of the connection end support portion 121a. It is preferable to have an overhang 12a2 at the end for suppressing the end of the flat portion 12b1 of the male connection end 12b.

雄型の接続端部12bは、雌型と同様にフラット部11の一方の端で上方に突設されて、フラット部11の長手方向に連続して延びる接続端支持部121bと、接続端支持部121bの上端に連続して形成される平坦部12b1とからなる。雄型の接続端部12bにおける平坦部12b1は、上面がフラット部11とほぼ平行でかつフラット部11の長手方向に延びる平坦面122bを有する。   The male connection end portion 12b protrudes upward at one end of the flat portion 11 in the same manner as the female mold, and continuously extends in the longitudinal direction of the flat portion 11, and the connection end support portion 121b.

The female connection end 12a and the male connection end 12b both have flat portions 12a1 and 12b1, and when they are combined, at least the flat portion of the female connection end is the male connection end. It is preferable to be configured in a shape that overlaps the flat part of the part.

図3に、接続端形状の他の例を断面図で示す。図3に示す例は、平坦部12a1,12b1を有し、さらに接続端支持部121a,121bと平坦部12b1,12a1とがほぼL字状を呈するとともに、雌部の平坦部12a1の一方の端12a3が金属板を密着状態に折り曲げた断面形状に構成された例である。雄部の接続端部の形状は、図1の例と同様とした。このような構造にすることにより、金属板が2枚重なり合う構造となり、構造上、強度増加が図れる。   FIG. 3 is a sectional view showing another example of the connection end shape. The example shown in FIG. 3 has flat portions 12a1 and 12b1, and the connection end support portions 121a and 121b and the flat portions 12b1 and 12a1 are substantially L-shaped, and one end of the flat portion 12a1 of the female portion. 12a3 is an example in which the metal plate is configured to have a cross-sectional shape bent in a close contact state. The shape of the connection end of the male part was the same as in the example of FIG. By adopting such a structure, a structure in which two metal plates overlap each other, and the strength can be increased structurally.

また、本発明の屋根用部材は、フラット部11に一条あるいは複数条のリブを備えてもよい。リブ13は、フラット部11の上方に突設され、フラット部11の長手方向に連続して延びる条として配設される。リブ13は、二枚の金属板を重ね合わせてなる重ね合わせ部13aと、重ね合わせ部13aの上端に上面が平坦な箱状部13bを有する。重ね合わせ部13aはフラット部11に連続して形成される。リブ13を一条、備えた例を断面図で図4に示す。なお、本発明ではリブは一条に限定されないことはいうまでもない。また、図4に示す箱状部13bは、横断面形状が三角形を呈しているが、本発明ではこれに限定されるものではない。三角形以外の四角形、五角形等の、上面が平坦な多角形状としてもよい。なお、重ね合わせ部13aは、長さ方向に所定の間隔をおいて、スポット溶接あるいは打抜き等により点接合してもよい。これにより、荷重が負荷されたときに重ね合わせ部が開くという問題は少なくなる。   Further, the roof member of the present invention may be provided with one or more ribs on the flat portion 11. The rib 13 protrudes above the flat portion 11 and is disposed as a strip that continuously extends in the longitudinal direction of the flat portion 11. The rib 13 includes an overlapping portion 13a formed by overlapping two metal plates, and a box-shaped portion 13b having a flat upper surface at the upper end of the overlapping portion 13a. The overlapping portion 13a is formed continuously with the flat portion 11. FIG. 4 is a sectional view showing an example in which one rib 13 is provided. In the present invention, it goes without saying that the rib is not limited to a single line. Further, the box-shaped portion 13b shown in FIG. 4 has a triangular cross-sectional shape, but the present invention is not limited to this. It is good also as polygonal shapes with a flat upper surface, such as quadrangle | tetragon other than a triangle and pentagon. The overlapping portion 13a may be spot-joined by spot welding or punching at a predetermined interval in the length direction. This reduces the problem that the overlapping portion opens when a load is applied.

本発明の屋根用部材の高さ、すなわち、接続端部12a,12bおよびリブ13の高さは50〜150mmの範囲内の高さHを有することが好ましい。高さHが50mm未満では、空気層の形成が少なく、断熱効果が少ない。一方、150mmを超えて高くなると、外圧荷重により変形しやくすくなるとともに、特性向上効果が飽和して使用する材料量に見合う部材特性の向上が得られなくなり、経済的に不利となる。   It is preferable that the height of the roof member of the present invention, that is, the height of the connecting end portions 12a and 12b and the rib 13 has a height H in the range of 50 to 150 mm. When the height H is less than 50 mm, the formation of an air layer is small and the heat insulation effect is small. On the other hand, when the height exceeds 150 mm, deformation is easily caused by an external pressure load, and the characteristic improvement effect is saturated, so that improvement in member characteristics corresponding to the amount of material to be used cannot be obtained, which is economically disadvantageous.

また、本発明の屋根用部材の幅方向長さは、とくに限定されないが、リブ13が配設されない場合には、雌型の接続端部および雄型の接続端部の間の間隔W(接続端支持部間隔)は、100〜600mmの範囲内とすることが好ましい。間隔が100mm未満では、屋根構造とする際に接続部が多くなり施工能率が低下するとともに、部材使用量が多くなり部材コストの高騰を招く。一方、600mmを超えて大きくなると、外圧荷重に対し変形しやすくなり、部材強度の低下を招く。リブ13を、幅方向に配設す場合には、リブと接続端(重ね合わせ部と接続端支持部との間隔)、あるいはリブ間の間隔W(重ね合わせ部間の距離)は、同様に100〜600mmの範囲内とすることが好ましい。間隔が100mm未満では、部材構成に必要な材料量が増加しすぎて部材コストの高騰を招く。なお、図4に示す例は、リブが1条の場合の例であるが、本発明ではこれに限定されなるものではないことはいうまでもない。   In addition, the length in the width direction of the roof member of the present invention is not particularly limited, but when the rib 13 is not provided, the interval W (connection between the female connection end and the male connection end is connected. The end support portion interval) is preferably in the range of 100 to 600 mm. If the interval is less than 100 mm, the number of connecting portions increases when the roof structure is formed, and the construction efficiency is lowered, and the amount of members used is increased, resulting in an increase in member costs. On the other hand, when it exceeds 600 mm, it becomes easy to be deformed against an external pressure load, resulting in a decrease in member strength. When the rib 13 is disposed in the width direction, the rib and the connecting end (the distance between the overlapping portion and the connecting end support portion) or the interval W between the ribs (the distance between the overlapping portions) is the same. It is preferable to be in the range of 100 to 600 mm. If the distance is less than 100 mm, the amount of material necessary for the member configuration increases too much, leading to an increase in member cost. In addition, although the example shown in FIG. 4 is an example in case of 1 rib, it goes without saying that the present invention is not limited to this.

なお、リブ間隔が大きくなり、部材強度が低下する恐れのある場合には、補強用として、図5に示すようなリブ間に1つ以上のサブリブ14を設けてもよい。サブリブ14の高さ、個数、間隔は、部材強度の向上程度に応じ適宜選択でき、とくに限定されるものではない。
また、本発明の屋根用部材では、フラット部11は、必ずしもその面が平面である必要はなく、曲面としてもよく、また表面に凹凸模様を付与してもよい。また、本発明の屋根用部材では、強度補強の観点から、フラット部11、接続端部12およびリブ13のいずれかあるいは全てにエンボス加工を施すこともできる。
In the case where there is a possibility that the rib interval becomes large and the member strength is lowered, one or more sub-ribs 14 may be provided between the ribs as shown in FIG. 5 for reinforcement. The height, number, and interval of the sub-ribs 14 can be appropriately selected according to the degree of improvement in member strength, and are not particularly limited.
In the roof member of the present invention, the flat portion 11 does not necessarily have to be a flat surface, and may be a curved surface or may be provided with an uneven pattern on the surface. In the roof member of the present invention, embossing can be applied to any or all of the flat portion 11, the connecting end portion 12, and the rib 13 from the viewpoint of reinforcing the strength.

上記した構成の屋根用部材の製造方法は、とくに限定されるものではないが、つぎのような方法で製造されることが好ましい。
金属板に、ロール成形加工により、幅方向にフラット部と、必要に応じ一条または所定間隔に設定した複数条のリブと、さらに両幅端における接続端部とを形成する工程と、剪断加工により所定長さの部材とする工程とにより、製品(屋根用部材)とされる。
Although the manufacturing method of the roof member having the above-described configuration is not particularly limited, it is preferably manufactured by the following method.
By forming a flat part in the width direction, a plurality of ribs set at one or a predetermined interval as necessary, and connecting end parts at both width ends by roll forming on the metal plate, and by shearing A product (roof member) is obtained through the process of forming a member having a predetermined length.

このようにして得られた上記した構造の本発明の屋根用部材1を1個または必要に応じて幅方向に複数個接続し、あるいはさらに屋根用部材を長さ方向に突き合わせて、所望の大きさ(幅×長さ)の屋根構造を形成することができる。そして、屋根用部材1の上側で、接続端部12a,12bの平坦部、あるいはリブ13の箱状部の上面を受け部として、所望厚さの断熱材2を積層し、さらに断熱材2を覆うように防水シート3を重ね、屋根面を形成する。なお、断熱材の下側に所定厚さの断熱材や下地ボード材を積層しても何ら問題はない。この状況を、図1〜図3に示した屋根用部材に対応して図6(a)〜(c)に模式的に示す。   One roof member 1 of the present invention having the above-described structure thus obtained is connected in the width direction as necessary, or the roof member is further abutted in the length direction to obtain a desired size. A roof structure (width × length) can be formed. Then, on the upper side of the roof member 1, the heat insulating material 2 having a desired thickness is laminated using the flat portions of the connection end portions 12 a and 12 b or the upper surface of the box-shaped portion of the rib 13, and further the heat insulating material 2 The waterproof sheets 3 are stacked so as to cover the roof surface. Note that there is no problem even if a heat insulating material or a base board material having a predetermined thickness is laminated on the lower side of the heat insulating material. This situation is schematically shown in FIGS. 6A to 6C in correspondence with the roof member shown in FIGS.

断熱材2は、長手方向に所定間隔を隔てて止め手段4である複数の止め具4bで、屋根用部材の接続端部12a,12bの組み合わせ部、あるいはさらにリブ13に固定される。断熱材2は、固定金具4aを介して止め具4bで固定されることが好ましい。なお、止め具4bは、ヒートバランスの観点から、突き出し長さが10〜20mmとなるように止めることが好ましい。止め具の突き出し長さが10mm未満では、結露発生の危険性が高くなるとともに、固定の安定性に不安が残る。一方、20mmを超えると、止め具コストが高くなる。なお、断熱材は、フラット部11上に所定の厚さ積層してもよい。   The heat insulating material 2 is fixed to the combined portion of the connecting end portions 12a and 12b of the roof member or further to the ribs 13 by a plurality of stoppers 4b which are the stopping means 4 at predetermined intervals in the longitudinal direction. It is preferable that the heat insulating material 2 is fixed by the stopper 4b via the fixing metal 4a. The stopper 4b is preferably stopped so that the protruding length is 10 to 20 mm from the viewpoint of heat balance. If the protruding length of the stopper is less than 10 mm, the risk of dew condensation increases and there is concern about the stability of fixing. On the other hand, if it exceeds 20 mm, the cost of the fastener increases. The heat insulating material may be laminated on the flat portion 11 with a predetermined thickness.

なお、本発明の屋根用部材を用いた屋根構造では、断熱材2を固定する止め具4bは金属板が2枚重なり合う構造となっている位置で使用される。これにより、接合強度は1枚の場合の約2倍に増加するという効果がある。
なお、断熱材2や下地ボード材としては、硬質ウレタンボード、発砲スチレンボード、ガラス繊維ボード、ロックウールボード、木片セメント板、木毛セメント板、フェノール樹脂系ボード等が例示できる。また、屋根面を形成する防水シート3は、塩化ビニル系シート、アスファルト系シート、ゴム系シート、エチレンプロパレン系シート、金属板等の材料とすることが好ましい。なお、防水シート3の重ね合わせ部や、防水シート3と下層の材料(例えば、デスク4a)との接合は、熱、溶剤、はぜ締め、接着剤等により行うことが好ましい。
In the roof structure using the roof member of the present invention, the stopper 4b for fixing the heat insulating material 2 is used at a position where two metal plates are overlapped. As a result, there is an effect that the bonding strength is increased to about twice that of a single sheet.
Examples of the heat insulating material 2 and the base board material include hard urethane board, foamed styrene board, glass fiber board, rock wool board, wood piece cement board, wood wool cement board, phenol resin board and the like. The waterproof sheet 3 forming the roof surface is preferably made of a material such as a vinyl chloride sheet, an asphalt sheet, a rubber sheet, an ethylene propylene sheet, or a metal plate. In addition, it is preferable to perform joining of the overlapping part of the waterproof sheet 3 and the waterproof sheet 3 and the lower layer material (for example, the desk 4a) by heat, a solvent, screwing, an adhesive, or the like.

上記した屋根構造とすることにより、施工後はもちろんとくに工事中の止水性が顕著に向上するとともに、断熱材2の下層に、対流が生じにくい所定量の空気層を確保でき、断熱効果が顕著に向上し、省エネルギーに貢献できる。また、フラット部により天井面を平坦に形成できるという効果がある。また、断熱材をフラット部11上に積層することにより、断熱性、遮音性がさらに向上する。   By using the above-described roof structure, the water-stopping property during construction is remarkably improved after construction, and a predetermined amount of air layer in which convection is unlikely to occur can be secured in the lower layer of the heat insulating material 2, and the heat insulation effect is remarkable. Can contribute to energy saving. Moreover, there exists an effect that a ceiling surface can be formed flat by a flat part. Further, by laminating the heat insulating material on the flat part 11, the heat insulating property and the sound insulating property are further improved.

また、より広い屋根空間を構成するために、屋根部材1同士を、長さ方向端部で突き合せる場合に、本発明の屋根構造では、図7(a)に示すように、屋根用部材1の端部同士の突合せ部101の下側近傍が、屋根用部材1の下側と梁50との間にシーリング材5を配設した構成を有することが好ましい。これにより、水密性・気密性が向上し突合せ部からの水漏れを防止することができ、施工後の防水はもちろん工事中の止水を効果的に行うことができる。シーリング材としては、水密性・気密性を有する不定形の材料、あるいは水密性・気密性を有するテープ状材料とすることが好ましい。シーリング材の材質としてはブチルゴム系、アスファルト瀝青材系、あるいはウレタン系、変性シリコン系とすることが好ましい。なお、シーリング材の厚さは、0.5〜1.5 mm程度とすることが好ましい。   Moreover, in order to comprise wider roof space, when roof members 1 are faced | matched by the edge part of a length direction, in the roof structure of this invention, as shown to Fig.7 (a), the member 1 for roofs is shown. It is preferable that the lower vicinity of the butted portion 101 between the end portions of the two has a configuration in which the sealing material 5 is disposed between the lower side of the roof member 1 and the beam 50. Thereby, watertightness and airtightness can be improved and water leakage from the butt portion can be prevented, and waterproofing during construction can be effectively performed as well as waterproofing after construction. The sealing material is preferably an amorphous material having water tightness and air tightness, or a tape-like material having water tightness and air tightness. The material of the sealing material is preferably butyl rubber, asphalt bituminous, urethane, or modified silicon. The thickness of the sealing material is preferably about 0.5 to 1.5 mm.

また、図7(b)に示すように、屋根用部材の端部同士の突合せ部101の下側近傍が、屋根用部材の下側から梁50との間にシーリング材5と高さ調整材6とをこの順に配設した構成を有することが好ましい。梁50がハイテンボルト等による継手部を有する場合には梁上面の高さが一定とならないため、梁50と屋根用部材1との間に、C型チャンネル等の高さ調整材6を介してシーリング材5を配置することが好ましい。   Further, as shown in FIG. 7B, the sealing material 5 and the height adjusting material are located near the lower side of the butted portion 101 of the ends of the roof member between the lower side of the roof member and the beam 50. 6 is preferably arranged in this order. When the beam 50 has a joint portion such as a high ten bolt, the height of the beam upper surface is not constant, and therefore, a height adjusting member 6 such as a C-shaped channel is interposed between the beam 50 and the roof member 1. It is preferable to arrange the sealing material 5.

(実施例1)
JIS G 3302に規定される溶融亜鉛めっき鋼板SGC 490(板厚:0.8mm)を用いて図6(b)に示す形状の屋根用部材(本発明例)を作製した。屋根用部材1は、めっき鋼板に、ロール成形加工により、幅方向にフラット部11と、所定間隔Wを隔てて1条の高さHのリブ13と、さらに両幅端に図2に示すような雄型の接続端部12b、雌型の接続端部12aを形成し、さらに、剪断加工により最大長さ(8m)に切断して使用した。この屋根用部材1同士を、雄型の接続端部12bと雌型の接続端部12aを組み合わせることにより、幅方向に接続した。これらを、梁50に載置して図6(b)に示すような屋根構造10を構成した。なお、屋根用部材1の上に、ボード状の断熱材2(厚み:30mm)を積層し、ディスク4aを介して止め具(ビス)4bで、接続端部12a,12bの組み合わせ部、およびリブ13の箱状部13bに固定した。ついで、断熱材2を塩化ビニル系防水材(シート:厚さ1.5mm)3で覆い、屋根を形成し本発明例とした。なお、ディスク4aの表面と防水シート3の裏面とを接着材で固定した。なお、リブと接続端部の幅方向の間隔Wを200mm、高さHを100mm、止め具突き出量Iを20mmとした。
Example 1
Using a hot-dip galvanized steel sheet SGC 490 (plate thickness: 0.8 mm) defined in JIS G 3302, a roof member (invention example) having the shape shown in FIG. 6B was produced. As shown in FIG. 2, the roof member 1 is formed on a plated steel plate by a roll forming process, with a flat portion 11 in the width direction, a rib 13 having a height H at a predetermined interval W, and further at both width ends. A male connecting end 12b and a female connecting end 12a were formed, and further cut into a maximum length (8 m) by shearing. The roof members 1 are connected in the width direction by combining the male connection end 12b and the female connection end 12a. These were placed on the beam 50 to form a roof structure 10 as shown in FIG. In addition, a board-like heat insulating material 2 (thickness: 30 mm) is laminated on the roofing member 1, and a combination part of connecting end portions 12a and 12b and a rib with a stopper 4b through a disk 4a. It was fixed to 13 box-like parts 13b. Next, the heat insulating material 2 was covered with a vinyl chloride waterproofing material (sheet: thickness 1.5 mm) 3 to form a roof, thereby obtaining an example of the present invention. The front surface of the disk 4a and the back surface of the waterproof sheet 3 were fixed with an adhesive. The interval W between the rib and the connecting end in the width direction was 200 mm, the height H was 100 mm, and the stopper protruding amount I was 20 mm.

なお、図10に示す屋根構造を従来例とした。使用した金属板、断熱材の種類、厚さ、止め具の大きさ等は本発明例と同様した。
上記した構造の屋根構造について、工事中の止水性、止め具(ビス)の引抜強度、断熱性、雨音減音効果、耐結露性を評価した。止め具の引抜強度は、引抜試験により求め、従来例を基準(1.0)として相対評価した。断熱性は、熱量流量を計算により求め、従来例を基準(○)にしてそれより優れている場合を◎、それより劣る場合を△とした。また、雨音減音効果は、人工的に降雨を実行し、その際の室内での平均音圧を測定し、従来例を基準(○)にして、それより優れる場合を◎、それより劣る場合を△とした。また、耐結露性は、外気温を−3℃、室内温度を15℃、室内湿度を50%の条件で、従来例を基準(○)としてそれより優れる場合を◎、それより劣る場合を△として評価した。また、断熱材を積層する前に、人工的に降雨を実行し、その際の雨量(フラット部に溜まる雨水のフラット面からの深さが10mm、20mm、50mm、100mmとなる雨量及び100mm超に相当する雨量に調整)と室内への漏れ状況の関係を調査し、漏れ発生時の雨量を求め、工事中の止水性を評価した。
Note that the roof structure shown in FIG. The metal plate used, the type of heat insulating material, the thickness, the size of the stopper, and the like were the same as in the present invention example.
The roof structure having the above-described structure was evaluated for water-stopping during construction, pull-out strength of stoppers (screws), heat insulation, rain noise reduction effect, and condensation resistance. The pull-out strength of the stopper was obtained by a pull-out test, and was evaluated relative to the conventional example as a standard (1.0). For the heat insulation, the heat flow rate was obtained by calculation, and the case where it was superior to that of the conventional example as the standard (◯) was marked ◎, and the case where it was inferior was marked △. In addition, the sound reduction effect of rain sound is artificially executed by rain, and the average sound pressure in the room at that time is measured. The case was marked △. Condensation resistance is ◎, when the outside temperature is -3 ° C, the room temperature is 15 ° C, and the room humidity is 50%. As evaluated. In addition, before laminating the insulation, artificial rain is performed, and the rainfall during that time (rain depth that accumulates on the flat part is 10 mm, 20 mm, 50 mm, 100 mm, and more than 100 mm). The relationship between the amount of rain and the leakage into the room was investigated, the amount of rainfall at the time of the occurrence of the leak was determined, and the waterstop during construction was evaluated.
