（３）（２）において、前記複数条のリブの間隔が100〜600mmの範囲内であることを特徴とする屋根・壁用部材。 The gist of the present invention is as follows.
(1) A roof / wall member comprising a metal plate, comprising a flat portion, and a plurality of ribs protruding above the flat portion and continuously extending in the longitudinal direction of the flat portion. , roof the ribs, to the overlapping portion continuous to the flat portion, is formed on the upper end of the overlapping portions, characterized in that it has a box-shaped portion to affix the insulation is laminated to the outer- Wall member.

(3) The roof / wall member according to (2), wherein an interval between the plurality of ribs is within a range of 100 to 600 mm.

本発明によれば、天井面、内壁面などの内装面の美観性に優れるとともに、断熱効果に優れ、しかも遮音性にも優れた、軽量の屋根または壁を安価に構成することができ、産業上格段の効果を奏する。また、本発明によれば、省エネルギーに寄与するいう効果もある。 According to the present invention, a lightweight roof or wall that is excellent in aesthetics of interior surfaces such as a ceiling surface and an inner wall surface, is excellent in heat insulation effect, and is also excellent in sound insulation, can be configured at low cost. Has an exceptional effect. In addition, according to the present invention, there is an effect of contributing to energy saving.

本発明の屋根用または壁用部材は、金属板で構成される。金属板としては、とくに限定されるものではないが、めっき鋼板、あるいはステンレス鋼板、塩化ビニル樹脂被覆鋼板などの鋼板、あるいはアルミニウム板等の非鉄金属板がいずれも好適に使用できる。また、めっき鋼板としては、耐食性の観点から亜鉛めっき鋼板とすることが好ましい。 The member for roof or wall of the present invention is composed of a metal plate. Although it does not specifically limit as a metal plate, Steel plates, such as a plated steel plate, a stainless steel plate, a vinyl chloride resin coating steel plate, or nonferrous metal plates, such as an aluminum plate, can be used conveniently. The plated steel sheet is preferably a galvanized steel sheet from the viewpoint of corrosion resistance.

本発明の屋根・壁用部材の一例を、図１に示す。図１（ａ）は斜視図、図１（ｂ）は幅方向断面図である。 An example of the roof and wall 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.

本発明の屋根・壁用部材１は、フラット部11と複数条のリブ12,12とを備える。リブ12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12は、二枚の金属板を重ね合わせてなる重ね合わせ部12aと、重ね合わせ部12aの上端に箱状部12bを有する。重ね合わせ部12aはフラット部11に連続して形成される。なお、図１に示す箱状部12b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12a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。 The roof / wall member 1 of the present invention includes a flat portion 11 and a plurality of ribs 12 and 12. The rib 12 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 12 has an overlapping portion 12a formed by overlapping two metal plates, and a box-shaped portion 12b at the upper end of the overlapping portion 12a. The overlapping portion 12a is formed continuously with the flat portion 11. In addition, although the box-shaped part 12b shown in FIG. 1 has a triangular cross-sectional shape, it is not limited to this in this invention. It is good also as polygonal shapes with a flat upper surface, such as quadrangle | tetragon other than a triangle and a pentagon. The overlapping portion 12a may be point-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.

また、リブ12a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。 The rib 12a preferably 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 insulating 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、リブ12aは、幅方向に複数条配設されるが、その間隔Ｗ(重ね合わせ部間の距離)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、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。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。なお、図１に示す例は、リブが２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。 A plurality of ribs 12a are arranged in the width direction, and the interval W (distance between overlapping portions) is preferably 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. On the other hand, becomes greater beyond 600 mm, it tends to deform to the outside pressure load, lowering the member strength. In addition, although the example shown in FIG. 1 is an example in case of 2 ribs, it cannot be overemphasized that it is not limited to this in this invention.

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２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、部材強度の向上要求の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。 When the rib interval is increased and the strength of the member may be reduced, one or more sub-ribs 14 may be provided between the ribs as shown in FIG. 2 for reinforcement. The height, number, and interval of the sub-ribs 14 can be appropriately selected according to the degree of request for improvement in member strength, and are not particularly limited.

また、本発明の屋根・壁用部材では、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・壁用部材では、強度補強の観点から、フラット部11および／またはリブ12にエンボス加工を施すこともできる。 In the roof / wall 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 addition, in the roof / wall member of the present invention, the flat portion 11 and / or the rib 12 can be embossed from the viewpoint of reinforcing the strength.

また、本発明の屋根・壁用部材の端部には、幅方向に所望の個数の屋根部材が接続可能なように、それぞれ雄型接続端13aおよび雌型接続端13bを有することが好ましい。図１に示す、接続端13a,13bは、鋼板を長さ方向にわたる折り曲げ加工により形成されたものであるが、本発明はこれに限定されるものではない。 Further, it is preferable that the end of the roof / wall member of the present invention has a male connection end 13a and a female connection end 13b, respectively, so that a desired number of roof members can be connected in the width direction. The connection ends 13a and 13b shown in FIG. 1 are formed by bending a steel plate in the length direction, but the present invention is not limited to this.

上記した構成の屋根・壁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。 Although the manufacturing method of the member for roofs / walls having the above-described configuration is not particularly limited, it is preferably manufactured by the following method.

金属板に、ロール成形加工により、幅方向にフラット部と所定間隔に設定した複数条のリブと、あるいはさらに両幅端における接続端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、あるいは壁用部材）とされる。 Forming a plurality of ribs set in a width direction and a plurality of ribs set at a predetermined interval in a width direction by a roll forming process, or a connecting end at both width ends, and a member having a predetermined length by a shearing process; By the process to do, it is set as a product (a member for roofs or a member for walls).

このようにして得られた上記した構造の本発明部材を１個または必要に応じて幅方向に複数個接続し、所望の大きさの屋根構造あるいは壁構造を形成することができる。また、これら部材に断熱材等の必要な材料を積層し、止め具で固定して、所望の構造の屋根構造、あるいは壁構造とすることができる。 One or more of the members of the present invention having the above-described structure thus obtained can be connected in the width direction to form a roof structure or wall structure having a desired size. In addition, a necessary material such as a heat insulating material can be laminated on these members and fixed with a stopper to form a roof structure or a wall structure having a desired structure.

上記した構造の本発明の屋根用部材、壁用部材を用いて、屋根構造、壁構造とすることにより、断熱材等の下層（内側）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、止め手段が箱状部内に隠れるとともに、フラット部により天井面を平坦に形成でき、内装面の美観を向上できるという効果もある。 By using the roof member and wall member of the present invention having the above-described structure, a predetermined amount of air layer in which convection is unlikely to occur can be secured in the lower layer (inside) of the heat insulating material, etc. The heat insulation effect is remarkably improved and can contribute to energy saving. In addition, the stopping means is hidden in the box-shaped portion, and the ceiling surface can be formed flat by the flat portion, so that the appearance of the interior surface can be improved.

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１に示す形状の壁用部材(本発明例)を作製した。壁用部材は、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２条の高さＨのリブ12と、さらに両幅端に雄、雌型の接続端13を形成し、さらに、剪断加工により最大長さ（12ｍ）に切断して、製品（壁用部材）とした。この製品を幅端の接続端により幅方向に接続した。これらを、柱に取り付けて壁を構成した。なお、壁用部材の外側にはボード状の断熱材（厚み：30mm）を積層し、止め具（ビス）でリブ12の箱状部12bに固定した。ついで、断熱材の上側を合成高分子系ハイブリッド防水材（厚み：1.5mm）で覆い、壁面を形成した。なお、止め具は、頭部に円盤状のディスク盤を設けたビスとし、ディスク盤の表面と防水材の裏面とを接着材で固定した。なお、リブの幅方向の間隔Ｗ、高さＨは、表１に示すように変化した。
なお、従来例は、壁部材として、図３に示すような、波型形状の金属製折板を用いた以外は、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。なお、金属製折板は、頂部と底部の間隔Ｗを100mm、頂部の高さＨを75 mmとする形状のめっき鋼板（板厚：1.2mm）製とした。 Using a galvanized steel sheet SGC 490 (plate thickness: 0.8 mm) defined in JIS G 3302, a wall member (invention example) having the shape shown in FIG. 1 was produced. The wall member is made of a plated steel plate by a roll forming process, a flat portion 11 in the width direction, ribs 12 having two heights H with a predetermined interval W, and male and female connections at both width ends. The end 13 was formed and further cut to the maximum length (12 m) by shearing to obtain a product (wall member). This product was connected in the width direction by the connecting end of the width end. These were attached to pillars to form walls. A board-like heat insulating material (thickness: 30 mm) was laminated on the outside of the wall member, and was fixed to the box-shaped portion 12b of the rib 12 with a stopper (screw). Next, the upper surface of the heat insulating material was covered with a synthetic polymer hybrid waterproof material (thickness: 1.5 mm) to form a wall surface. The stopper was a screw having a disk-shaped disk on the head, and the surface of the disk and the back of the waterproof material were fixed with an adhesive. The interval W and the height H in the width direction of the ribs changed as shown in Table 1.
The conventional example uses the corrugated metal folded plate as shown in FIG. 3 as the wall member, except for the type of insulation, the thickness, the size of the stopper, etc. Same. The metal folded plate was made of a plated steel sheet (plate thickness: 1.2 mm) having a shape in which the distance W between the top and bottom was 100 mm and the height H of the top was 75 mm.
