Description

本発明は、建造物の外壁、天井、化粧屋根等として用いられる有孔スクリーンを構築するための金属板製有孔パネルに関する。 The present invention relates to a metal perforated panel for constructing perforated screens to be used as exterior walls, ceilings, decorative roofs, etc. of buildings.

建造物の壁、天井、化粧屋根として用いられる有孔スクリーンを構築するための金属製有孔パネルが従来知られている（例えば特許文献１参照）。 Metal perforated panels for constructing perforated screens to be used as walls, ceilings, and decorative roofs of buildings are conventionally known (see, for example, Patent Document 1).

特開２０１９０－８２０１４号公報JP 20190-82014 A

従来の此種の有孔パネルの側部には、ビスでパネル本体を下地材に固定するための取付縁部が形成されている。取付縁部はパネル本体に対して外向きに形成されているものと内向きに形成されているものがある。
有孔パネルの本体の左右両側に外向き取付縁部が形成されている構成において、外向き取付縁部の切断端面が開放されていると、取付縁部の端部が鋭利な状態となり、そのため有孔パネルを用いた有孔スクリーンの施工中や施工後に有孔パネルの取付縁部の端面でケガをする事故が発生する恐れがある。
また、有孔パネルに用いる薄い金属板の加工時に、金属板の端部に変形が発生するという問題点がある。また、有孔パネルの本体を薄い金属板で構成すると、風圧に対して十分な強度が得られないという問題点がある。
本発明は、上記問題点を解決することを目的とするものである。 Conventional perforated panels of this type have mounting edges formed on the sides for fixing the panel body to the base material with screws. The mounting edges are either formed facing outward or inward with respect to the panel body.
In a configuration in which an outward mounting edge is formed on both the left and right sides of the main body of a perforated panel, if the cut end surface of the outward mounting edge is open, the end of the mounting edge will be sharp, which may result in injury from the end surface of the mounting edge of the perforated panel during or after the installation of a perforated screen using the perforated panel.
In addition, there is a problem that deformation occurs at the edge of the thin metal plate when processing the thin metal plate used for the perforated panel. Also, if the main body of the perforated panel is made of a thin metal plate, there is a problem that it does not have sufficient strength against wind pressure.
An object of the present invention is to solve the above problems.

上記目的を達成するため、本発明は、所定の長さの横幅と所定の長さの縦幅を有する金属板から成るパネル本体１０の左右両側に取付縁部１４，１６を形成し、パネル本体１０の前記取付縁部１４，１６間に凸起部１２を形成し、凸起部１２の平板部２０に複数の孔１８を形成し、取付縁部１４，１６を下地材６にビス止めできるようにし、パネル本体１０の左右両側の取付縁部１４，１６に折り返し屈曲部２４を形成し、該屈曲部２４によってパネル本体１０の左右両側の取付縁部１４，１６の端部に、パネル本体１０の縦方向の全長に亘って屈曲面２６を形成したことを特徴とする。
また、本発明は、前記凸起部１２を平板部２０と、該平板部２０の両側に垂直に形成された側板部２２とで構成し、凸起部１２にパネル本体４の縦方向の全長に亘って伸びるわん曲部から成る補強用リブ３０を形成したことを特徴とする。
また、本発明は、前記折り返し屈曲部２４を取付縁部１４，１６の裏側に屈曲したことを特徴とするものである。 In order to achieve the above-mentioned object, the present invention is characterized in that mounting edge portions 14, 16 are formed on both the left and right sides of a panel body 10 made of a metal plate having a horizontal width of a predetermined length and a vertical width of a predetermined length, a protruding portion 12 is formed between the mounting edge portions 14, 16 of the panel body 10, a plurality of holes 18 are formed in a flat portion 20 of the protruding portion 12 so that the mounting edge portions 14, 16 can be fixed to a base material 6 with screws, a folded-back bent portion 24 is formed on the mounting edge portions 14, 16 on both the left and right sides of the panel body 10, and a bent surface 26 is formed over the entire vertical length of the panel body 10 at the ends of the mounting edge portions 14, 16 on both the left and right sides of the panel body 10 by the bent portion 24.
The present invention is also characterized in that the protruding portion 12 is composed of a flat plate portion 20 and side plate portions 22 formed perpendicularly on both sides of the flat plate portion 20, and a reinforcing rib 30 consisting of a curved portion extending over the entire vertical length of the panel main body 4 is formed on the protruding portion 12.
The present invention is also characterized in that the folded-back portion 24 is bent toward the rear side of the mounting edges 14, 16.

本発明は、上述の如く構成したので、有孔パネルの側端部に鋭利な部分が形成されることがないので作業者が安全に有孔スクリーンの施工を行うことができるとともに、有孔スクリーンに安全に接触することができる。
また、有孔スクリーンの凸起部に補強リブを設けたので、風圧など外部からの圧力に対して強度の高い有孔スクリーンを提供することができる。 Since the present invention is configured as described above, no sharp parts are formed on the side ends of the perforated panel, so workers can safely install the perforated screen and can safely contact the perforated screen.
Furthermore, since reinforcing ribs are provided on the protruding portions of the perforated screen, it is possible to provide a perforated screen that is strong against external pressure such as wind pressure.

以下に本発明の構成を添付した図面を参照して詳細に説明する。
図２は、建造物の外壁やエントランスロビーの天井を構成するための光と風を透過することのできる有孔スクリーン２の正面図を示している。有孔スクリーン２は単体の一本の金属製有孔パネル４をルーバーのように用いて構成したり、あるいは複数の有孔パネル４を横方向に並列状に接合して外壁、天井などを構成するために用いられる。
図１は、有孔スクリーンを構成する有孔パネル４の横断面平面図を示している。有孔パネル４は、図３に示すように建造物の野縁（下地材）６にビス８によって固定される。有孔パネル４は、有孔金属板から成る縦長のパネル本体１０に凸起部１２と、凸起部１２の両側の縁部の全長に亘って形成された取付縁部１４，１６とから構成されている。凸起部１２と各取付縁部１４，１６の横幅は適宜設定されている。凸起部１２は、本体１０の左右両側の取付縁部１４，１６に対して段差が形成されるように深く表面方向に突出して屈折されデザイン性を高めている。本体１０に形成された孔１８の形状と個数配置は、独自性のあるデザインに基づいて適宜定められている。 The configuration of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 2 shows a front view of a light- and wind-transmitting perforated screen 2 for use in constructing the exterior wall of a building or the ceiling of an entrance lobby. The perforated screen 2 is constructed using a single metal perforated panel 4 like a louver, or multiple perforated panels 4 joined in parallel in the horizontal direction to form an exterior wall, ceiling, etc.
FIG. 1 shows a cross-sectional plan view of a perforated panel 4 constituting a perforated screen. The perforated panel 4 is fixed to a building frame (base material) 6 with screws 8 as shown in FIG. 3. The perforated panel 4 is composed of a vertically long panel body 10 made of a perforated metal plate, a protruding portion 12, and mounting edges 14, 16 formed over the entire length of the edges on both sides of the protruding portion 12. The widths of the protruding portion 12 and the mounting edges 14, 16 are appropriately set. The protruding portion 12 is deeply protruded and bent toward the surface so as to form a step with respect to the mounting edges 14, 16 on both the left and right sides of the body 10, thereby enhancing the design. The shape and number of holes 18 formed in the body 10 are appropriately determined based on a unique design.

凸起部１２は、横断面形状が図１中、左右水平方向に延びる平板部２０と、これに対して垂直な側板部２２，２２とから形成されている。取付縁部１４，１６の側端部には、内向きに、折り返し屈曲部２４，２４が形成され、該屈曲部２４，２４によって、取付縁部１４，１６の側端部に屈曲面２６，２６が形成されている。折り返し屈曲部２４，２４の横幅は、本実施形態では、取付縁部１４，１６の横幅の約1/３～1/２に設定されている。有孔パネル４の凸起部１２の側板部２２と平板部２０には、補強用のリブ３０が形成されている。リブ３０は、図１に示すように側板部２２と平板部２０の全長に亘って延びるわん曲部を屈曲形成して構成している。リブ３０の形状は、凸起部１２の内側に屈曲させた図１に示す形状以外に、図４に示すように四角形状に突起する形状としてもよい。取付縁部１４，１６は同一平面上に形成され、平板部２０に対して平行に形成されている。 The protruding portion 12 is formed of a flat plate portion 20 whose cross-sectional shape extends horizontally in FIG. 1, and side plate portions 22, 22 perpendicular to the flat plate portion 20. At the side end of the mounting edge portion 14, 16, a folded-back portion 24, 24 is formed facing inward, and the folded-back portion 24, 24 forms a bent surface 26, 26 at the side end of the mounting edge portion 14, 16. In this embodiment, the width of the folded-back portion 24, 24 is set to about 1/3 to 1/2 of the width of the mounting edge portion 14, 16. A reinforcing rib 30 is formed on the side plate portion 22 and flat plate portion 20 of the protruding portion 12 of the perforated panel 4. The rib 30 is formed by bending a curved portion that extends over the entire length of the side plate portion 22 and flat plate portion 20 as shown in FIG. 1. The shape of the rib 30 may be a rectangular protruding shape as shown in FIG. 4, other than the shape shown in FIG. 1 in which the rib 30 is bent inward from the protruding portion 12. The mounting edges 14 and 16 are formed on the same plane and parallel to the flat plate portion 20.

上記した構成において、１本の有孔パネル４によって有孔スクリーン２を構築する場合には、図３に示すように下地材６に有孔パネル４の取付縁部１４，１６をビス８により固定する。折り返し屈曲部２４を取付縁部１４，１６の裏側に屈曲したことで、折り返し屈曲部２４を有孔スクリーン２の表面から隠すことができ、有孔スクリーン２の表面の外観が折り返し屈曲部２４によって損なわれるのを防止することができる。
図５は、凸起部１２の両側の取付縁部１４，１６の一方を、外向き取付縁部１４，他方を凸起部１２の内側方向に屈折した内向き取付縁部１６ａとした実施形態を示している。このように、有孔パネル４に内向き取付縁部１６aと外向き取付縁部１４を構成することで、図６に示すように隣接する複数の有孔パネル４を隙間なく隣接配置でき、重ね合わせた外向き取付縁部１４と内向き取付縁部１６aを下地材６にビス止めすることで複数本の有孔パネル４から成る有孔スクリーン２を構築することができる。尚、図６中、リブは、図示省略されている。 In the above-mentioned configuration, when constructing the perforated screen 2 using one perforated panel 4, the mounting edges 14, 16 of the perforated panel 4 are fixed to the base material 6 with screws 8 as shown in Figure 3. By bending the folded-back bent portion 24 to the back side of the mounting edges 14, 16, the folded-back bent portion 24 can be hidden from the surface of the perforated screen 2, and the appearance of the surface of the perforated screen 2 can be prevented from being marred by the folded-back bent portion 24.
Fig. 5 shows an embodiment in which one of the mounting edges 14, 16 on both sides of the protruding portion 12 is an outward mounting edge 14, and the other is an inward mounting edge 16a bent inwardly of the protruding portion 12. By configuring the inward mounting edge 16a and the outward mounting edge 14 in this way on the perforated panel 4, it is possible to arrange adjacent multiple perforated panels 4 without gaps as shown in Fig. 6, and a perforated screen 2 made up of multiple perforated panels 4 can be constructed by fastening the overlapping outward mounting edge 14 and the inward mounting edge 16a to the base material 6 with screws. Note that ribs are omitted from Fig. 6.

この実施形態では、有孔パネル４に形成された多数の孔１８の中の一部はドリルビス操作作業用の空間部として内向き取付縁部１６aと対向する所定の部分に配置されている。図５に示す実施形態では、内向き取付縁部１６aには、下向きに折り返された折り返し屈曲部２４によって屈曲面２６が形成されている。図７は、複数本の有孔パネル４を並列に並べ、隣接する有孔パネル４の取付縁部１４，１６を突きつけた状態で取付縁部１４，１６を下地材６にビス８止めした有孔スクリーン２を示している。また、図８は、複数本の有孔パネル４を並列に並べ、隣接する有孔パネル４の取付縁部１４，１６を重ねた状態で、下地材にビス（図示省略）止めした有孔スクリーン２を示している。 In this embodiment, some of the many holes 18 formed in the perforated panel 4 are arranged in a predetermined portion facing the inward mounting edge 16a as a space for drill screw operation. In the embodiment shown in FIG. 5, the inward mounting edge 16a has a bent surface 26 formed by a folded bent portion 24 folded downward. FIG. 7 shows a perforated screen 2 in which multiple perforated panels 4 are arranged in parallel, and the mounting edges 14, 16 of adjacent perforated panels 4 are butted against each other, and the mounting edges 14, 16 are secured to the base material 6 with screws 8. FIG. 8 shows a perforated screen 2 in which multiple perforated panels 4 are arranged in parallel, and the mounting edges 14, 16 of adjacent perforated panels 4 are secured to the base material with screws (not shown) in a state where they are overlapped.

図９は、複数の有孔パネル４の表と裏を組み合わせて有孔スクリーン２を構築した実施形態を示している。尚、図８中、リブは、図示省略されている。
図９中、複数本の有孔パネル４，４は、表側が有孔スクリーン２の表面を向くように並列配置され、複数本の有孔パネル４，４は、裏側が有孔スクリーン２の表面を向くように並列配置され、表側が、有孔スクリーン２の表面を向く有孔パネル４，４は、取付縁部１４，１６が、下地材６にビス８止めされ、裏側が有孔スクリーン２の表面を向く有孔パネル４，４は、平板部２０が下地材６にビス８止めされている。
このように複数有孔パネル４の表裏を組み合わせて有孔パネル４を下地材６にビス止めすることで強度の高い有孔スクリーン２を構築することができる。 9 shows an embodiment in which a perforated screen 2 is constructed by combining the front and back of a plurality of perforated panels 4. Note that ribs are omitted from FIG.
In Figure 9, multiple perforated panels 4, 4 are arranged in parallel with their front sides facing the surface of the perforated screen 2, and multiple perforated panels 4, 4 are arranged in parallel with their back sides facing the surface of the perforated screen 2, and the perforated panels 4, 4 with their front sides facing the surface of the perforated screen 2 have their mounting edges 14, 16 fixed to the base material 6 with screws 8, and the perforated panels 4, 4 with their back sides facing the surface of the perforated screen 2 have their flat portions 20 fixed to the base material 6 with screws 8.
In this way, by combining the front and back of multiple perforated panels 4 and screwing the perforated panels 4 to the base material 6, a highly strong perforated screen 2 can be constructed.
